Blocking device for ostomy

Technical Field

The utility model relates to the field of medical equipment, concretely relates to block formula external member for fistulization.

Background

Colorectal cancer is one of the most common malignant tumors of the digestive tract, and has the characteristics of high morbidity, high mortality and the like. Surgical resection is currently the most effective treatment for colorectal cancer. However, anastomotic leakage is one of the most serious and common postoperative complications after lower rectal cancer (with the lower margin of the tumor < 7cm from the anus) has passed through the anterior resection of abdominal rectal cancer. The traditional prevention and treatment method is colon or ileum terminal ostomy, and the operation method reduces the pressure and infection risk of the intestinal tract at the near end of the anastomotic stoma by diverting excrement, thereby playing a role in protecting the anastomotic stoma. However, the operation has disadvantages that the patient needs to make a stoma for 3-6 months, and the patient needs to perform a secondary stoma receiving operation in the later period, which brings great pressure to the psychology and physiology of the patient and increases the economic burden of the patient; in addition, the secondary stoma surgery is suspected of overtreatment for the vast majority of patients who do not have anastomotic leakage.

In ostomy, a stoma is usually used, a balloon is arranged outside the input end of the stoma, the balloon is communicated with an inflation and drainage connector arranged outside the stoma, and liquid/gas can be filled into the inner cavity of the balloon through the inflation and drainage connector, so that the balloon can prop up to block the intestinal canal. However, when the intestinal content is blocked in the intestinal canal by the existing balloon, because a section of tube section which cannot be expanded is arranged between the expanded balloon and the inlet end part of the fistulization tube, a groove area is formed by enclosing the outer surface of the tube section, the outer surface of the upper edge of the balloon and the tube wall of the intestinal canal, the intestinal content is easily collected in the groove area, so that part of the intestinal content is embedded in the groove area and cannot be smoothly discharged, and bad influence can be brought to the postoperative recovery of a patient.

Detailed Description

In order to make the objects and advantages of the present application more apparent, the present application will be described in detail with reference to the following examples. It is understood that the following text is intended only to describe one or several particular embodiments of the application and does not strictly limit the scope of the claims which are specifically claimed herein, and that the examples and features of the examples in this application may be combined with one another without conflict.

In order to solve the above problems, referring to fig. 1 to 23, the present embodiment provides a blocking-type tube placement ostomy kit, comprising a fistulation tube 100, a balloon 200 and a charging and discharging connector 310, wherein the lumen of the fistulation tube 100 is used for flowing intestinal contents, two ends of the fistulation tube 100 along the length direction of the tube are respectively marked as an end a and an end B, the end a of the fistulation tube 100 is provided with an inlet 110 for the inflow of the intestinal contents, and the end B of the fistulation tube 100 is provided with an outlet 120 for the discharge of the intestinal contents; wherein the intestinal content comprises at least one of feces and body fluid, and the fistulization tube 100 is arranged in the patient at the A end and outside the patient at the B end when in use. The saccule 200 is wrapped on the outer tube wall close to the end A of the fistulization tube 100, the saccule 200 is made of deformable materials, the saccule 200 has at least two states, one state is that the saccule 200 is in a supporting state, and a closed structure for blocking intestinal contents is formed between the saccule 200 and the intestinal tube so as to limit the intestinal contents from flowing to an anastomotic stoma; secondly, the balloon 200 is in a retracted state to facilitate insertion/extraction of the a-end of the ostomy tube 100 into/from the patient; the inflation and drainage joint 310 is arranged outside the fistulization tube 100, the inflation and drainage joint 310 is communicated with the inner cavity of the balloon 200, the balloon 200 is switched to a support state by inflating gas/liquid into the inner cavity of the balloon 200 through the inflation and drainage joint 310, and the balloon 200 is switched to a retraction state by exhausting the gas/liquid in the balloon 200 through the inflation and drainage joint 310, wherein the retraction state refers to a state that the inner cavity of the balloon 200 is retracted to the minimum, and the inflation and drainage joint 310 is arranged outside a patient body when in use.

After the colorectal anastomosis operation of a patient, the end A of the fistulation tube 100 and the balloon 200 are placed into an abdominal cavity through a puncture hole on the lower right abdomen, then a purse is made on the intestinal tube which is 10-15 cm away from the ileocecal part, an incision is made in the center of the purse, the end part of the end A of the fistulation tube 100 and the balloon 200 are placed into the intestinal tube through the incision, and the inlet 110 of the end A faces towards the input loop. Liquid or gas is injected into the balloon 200 through the inflation and drainage joint 310 to ensure that the balloon 200 is switched to a support state so as to block intestinal contents from flowing through an anastomotic stoma, the A end of the fistulization tube 100 is fixed in the intestinal tube without displacement, and the appropriate inflation amount of the balloon 200 is ensured by observing the state of the intestinal wall so as to prevent the intestinal wall from being subjected to ischemic necrosis due to over-pressure. Next, the purse string is tightened to prevent the balloon 200 from being pulled out, and finally, the intestinal tube portion with the balloon 200 is pulled to the puncture, and the intestinal wall and the abdominal wall are sutured to fix the intestinal tube. During post-operative use, intestinal contents such as intestinal stool and intestinal fluid flow into the lumen of the fistula 100 through the inlet 110 of the fistula 100 and are then discharged through the outlet 120 of the fistula 100. In addition, a negative pressure drainage device can be connected to the outlet 120 of the fistulization tube 100 to improve the discharge efficiency and effect of intestinal contents.

After the anastomotic stoma of the patient is healed, the stoma can heal automatically only by evacuating liquid or gas in the balloon 200 and then pulling out the stoma gently, so that a secondary operation is not needed.

Wherein the anastomotic stoma is the anastomotic stoma generated by the intestinal canal ascending colorectal anastomosis operation; the input loop refers to an intestinal section above the intestinal canal incision; the inlet 110 and the outlet 120 of the fistulation tube 100 are respectively the orifices at both ends of the fistulation tube 100.

In the present embodiment, the blocking-type tube-setting ostomy kit is applied by placing the a end of the ostomy tube 100 into the upstream intestine of the anastomotic stoma in the intestinal tract of the patient, placing the B end of the ostomy tube 100 outside the body of the patient, placing the inlet 110 at the a end of the ostomy tube 100 for inflow of intestinal contents, and placing the outlet 120 at the B end of the ostomy tube 100 for outflow of intestinal contents; by adjusting the balloon 200 placed in the intestinal canal to a support state to block the intestinal contents from flowing to the anastomotic orifice located downstream, by adjusting the balloon 200 placed in the intestinal canal to a retraction state, the ostomy tube 100 can be conveniently pulled out of the body of the patient after the anastomotic orifice is healed; the balloon 200 may be inflated with a liquid/gas via inflation and deflation fitting 310 to effect switching of the adjustment balloon 200 between the inflated and deflated states. Through adopting above-mentioned scheme, owing to can block intestinal content flow direction anastomosis stoma through abundant sacculus 200 before the healing of anastomosis stoma to greatly reduced is to the interference of anastomosis stoma healing process, and through the state of adjusting sacculus 200 to the state of retracting after the healing of anastomosis stoma, can conveniently extract out fistulization pipe 100, the fistulization mouth can heal up by oneself, thereby avoids carrying out the secondary and still receives the art to the patient.

The inflation and deflation fitting 310 also typically has a one-way valve for preventing self-deflation of the liquid/gas filled into the balloon 200, and the fitting with such a one-way valve can be implemented using existing medical fittings.

Referring to fig. 6 to 8 and 21 to 23, the balloon 200 is made of a soft elastic tubular body, the tubular body is sleeved on the outer wall of the ostomy tube 100 near the end a, the outer wall of the end of the tubular body near the end a of the ostomy tube 100 is fixedly connected with the outer wall of the ostomy tube 100, the inner wall of the end of the tubular body far away from the end a of the ostomy tube 100 is fixedly connected with the outer wall of the ostomy tube 100, and after the balloon 200 is propped up, the part of the balloon 200 near the end a of the ostomy tube 100 extends towards the inlet 110 of the ostomy tube 100 along the tube length direction of the ostomy tube 100. By this scheme, one end of the balloon 200 close to the inlet 110 of the ostomy tube 100 can gradually extend towards the end part A of the ostomy tube 100 during the process of supporting the balloon 200, so that the inlet 110 of the ostomy tube 100 can gradually retract into the range covered by the balloon 200. The implementation has the advantages that after the saccule 200 is completely supported in the intestinal canal, the containing spaces among the saccule 200, the outer tube wall between the end part A of the ostomy tube 100 and the saccule 200 and the intestinal canal are greatly reduced or even eliminated, so that the retention of intestinal contents at the end part A of the ostomy tube 100 can be greatly reduced, and the intestinal contents can be fully drained out of the ostomy tube 100; in addition, since the balloon 200 can wrap part/all of the inlet 110 after being fully expanded, the intestinal wall is prevented from blocking the inlet 110, and the patency at the inlet 110 of the fistula tract 100 can be ensured.

In practice, the tubular body may be adhesively secured to the outer wall of the ostomy tube 100. The bonding position of the balloon 200 at the upper edge is positioned at the inner side of the balloon 200; the bonding part of the balloon 200 at the lower edge is positioned outside the balloon 200. When sacculus 200 is not full, the pipe wall is hugged closely to sacculus 200 wall, makes things convenient for the body to stretch into the intestinal, and when sacculus 200 was full back, sacculus 200 can wrap up sharp-end body completely, avoids the intestines content to inlay between sharp-end pipe wall and intestinal wall. Wherein, the bonding position of the balloon 200 at the upper edge is the bonding position of the tubular body close to the inlet 110 end of the fistulation tube 100; the lower edge of the balloon 200 is the area of the tubular body distal to the inlet 110 of the fistula 100.

Further, referring to fig. 6, and fig. 21 to 23, the junction between the outer wall of the end of the tubular body close to the end of the fistula 100A and the outer wall of the fistula 100 is located at the end of the fistula 100A, the inlet 110 of the fistula 100 is exposed outside the balloon 200 before the balloon 200 is fully inflated, and the whole/part of the inlet 110 of the fistula 100 is wrapped inside the balloon 200 after the balloon 200 is fully inflated. This embodiment may further improve the patency of the inlet 110 of the fistula tract 100 by securing the outer wall of the tubular body at the end of the body proximal to the end of the fistula tract 100A, which may increase the coverage of the inlet 110 within the balloon 200 after the balloon 200 is inflated. The conventional balloon 200 is mounted in such a manner that inner walls of both ends of a tubular body are fixedly connected to an outer wall of the ostomy tube 100, and even if the mounting position of the balloon 200 is close to the edge of the inlet, it is difficult to wrap the inlet after the balloon 200 is completely supported.

Referring to fig. 6 to 11, the external profile of the inlet 110 end of the ostomy tube 100 is beveled/flat/fishmouth shaped. Wherein, the inlet 110 end of the fistulization tube 100 is also the end of the A end of the fistulization tube 100; the shape of the bevel opening is that the end surface of the inlet 110 end of the fistulation tube 100 forms an included angle with the length direction of the fistulation tube 100; the flat mouth shape means that the end face of the inlet 110 end of the ostomy tube 100 is arranged perpendicular to the tube length direction of the ostomy tube 100; the fishmouth shape is that a V-shaped or V-shaped similar notch is arranged in the middle of the end face of the flat inlet 110, and the fishmouth shape is like the shape of the open fishmouth when viewed from the side. When the outer contour of the inlet 110 end of the fistulization tube 100 is in a bevel cut shape, after the balloon 200 is completely supported, the part of the inlet 110 of the fistulization tube 100 is retracted into the inner side of the balloon 200; when the outer contour of the inlet 110 end of the fistulization tube 100 is flat, the inlet 110 of the fistulization tube 100 can be completely retracted into the balloon 200 after the balloon 200 is completely supported; when the outer contour of the inlet 110 end of the ostomy tube 100 is fish-mouth-shaped, the inlet 110 of the ostomy tube 100 is partially retracted into the balloon 200 after the balloon 200 is fully supported.

In order to effectively reduce the amount of the intestinal contents retained outside the ostomy tube 100 between the balloon 200 and the inlet 110, the outer contour of the inlet 110 end of the ostomy tube 100 may be preferably configured to be flat in implementation, so that when the balloon 200 is installed, the end of the balloon 200 close to the inlet 110 may be arranged at the tail end part of the ostomy tube 100 as much as possible; however, a part of the tube body of each of the inlet 110 end of the bevel opening and the inlet 110 end of the fish mouth shape is incomplete, and in order to ensure the sealing performance of the balloon 200, it is generally not suitable to fix the end of the balloon 200 close to the inlet 110 at a position close to the edge of the end of the fistula 100, so that after the two types of inlet 110 ends are installed on the balloon 200, the inlet 110 of the fistula 100 cannot be completely retracted into the inner side of the balloon 200 in the supporting state of the balloon 200, and therefore, a large amount of intestinal contents can be left at the end of the balloon 200, which is inconvenient to clean.

Referring to fig. 1, 2 and 11, for a stoma 100 in which the external contour of the inlet 110 end of the stoma 100 is a beveled shape, a murphy hole 111 may be provided in the wall of the stoma 100 at the inlet 110, and the murphy hole 111 may be used to drain intestinal contents into the cavity of the stoma 100 from the inlet 110 in case the inlet is blocked by the intestinal wall. The murphy pores 111 are exposed outside the balloon 200 in the fully-expanded state of the balloon 200.

For the fistulization tube 100 with the fish mouth-shaped outer contour at the inlet 110 end of the fistulization tube 100, as the tube walls at two sides of the fish mouth-shaped opening can play a certain supporting role for the intestinal wall, and then the fistulization tube is used in combination with the balloon 200, when the balloon 200 is completely supported, the inlet 110 can be prevented from being completely blocked. Therefore, when the fistula 100 having the fish-mouth shaped entrance 110 end is used, the Murphy's eye 111 may not be provided.

The above-mentioned charging and discharging joint 310 is placed outside the patient after the operation, and if not fixed or reasonably stored, it will not only affect the comfort of the patient in daily life, but also may reduce the service life of the related structures such as the charging and discharging joint 310. In this regard, referring to fig. 1, 2, 5, 7 and 8, the present embodiment further provides a receiving member 500, the receiving member 500 is mounted on the fistula 100 and located outside the fistula 100, and the receiving member 500 is disposed corresponding to the inflation/deflation joint 310 for receiving the inflation/deflation joint 310.

Further, referring to fig. 5 and 8, the receiving member 500 is provided with an a-shaped hollow portion 510, and the a-shaped hollow portion 510 is adapted to the shape and structure of the charging and discharging connector 310 and is used for accommodating the charging and discharging connector 310.

The fistula 100 is intended to drain intestinal contents that are blocked upstream of the stoma, and therefore the fistula 100 needs to be cleaned regularly to ensure that the fistula 100 is hygienic and meets the requirements of normal use. To this end, the present embodiment further provides a flushing connector 410, and referring to fig. 1 to 8, the flushing connector 410 is disposed outside the ostomy tube 100, a flushing tubule 420 is disposed in/in the wall of the ostomy tube 100, one end of the flushing tubule 420 is connected to the flushing connector 410, and the other end is communicated with the lumen of the ostomy tube 100. Wherein, the flushing connector 410 is arranged outside the patient body when in use, the flushing tubule 420 is filled with flushing liquid through the flushing connector 410, and the flushing liquid flows out from the other end of the flushing tubule 420 and flushes the lumen of the fistulization tube 100. The flushed liquid is discharged through the outlet 120 of the ostomy tube 100; under the condition that negative pressure drainage device is connected at export 120, can utilize the flush fluid of negative pressure suction in the fistulization pipe 100 to the flush fluid of rapid flow to export 120 also can be washed out the lumen of fistulization pipe 100, improves and washes the effect.

In order to facilitate the reasonable storage of the flushing connector 410 and prevent the flushing connector 410 from being placed at will and affecting the comfort of the daily life of the patient and the service life of the flushing connector 410 and other related structures, referring to fig. 1 to 8, the storage piece 500 further comprises a B-shaped hollow part 520 for accommodating the flushing connector 410, and the B-shaped hollow part 520 is matched with the shape and structure of the flushing connector 410.

The storage piece 500 is made of hard materials, the charging and discharging connector 310 and the flushing connector 410 are fixedly mounted on the storage piece 500, the orientation of the interface of the charging and discharging connector 310 and the length direction of the fistulation tube 100 form an included angle A, the orientation of the interface of the flushing connector 410 and the length direction of the fistulation tube 100 form an included angle B, and the included angles A, B point to the end B of the fistulation tube 100. Wherein the interface of the inflation and deflation joint 310 is disposed near the B-end of the ostomy tube 100 for connecting an external device to perform inflation/deflation of the balloon 200; the interface of the irrigation fitting 410 is also disposed near the B-end of the ostomy tube 100 for connection to an external device for irrigating the interior of the ostomy tube 100.

In order to understand the filling state of the balloon 200 in the daily use process and intuitively understand whether the gas or liquid in the balloon 200 is emptied when the gas/liquid in the balloon 200 is discharged after the intestinal anastomosis is healed, referring to fig. 1 to 3, 5 and 7, the embodiment further provides a filling and discharging tubule 320 and an indicating balloon body connected in series in the pipeline of the filling and discharging tubule 320, the filling and discharging tubule 320 is arranged in the wall/lumen of the fistula 100, one end of the filling and discharging tubule 320 is connected with the filling and discharging joint 310, and the other end is communicated with the lumen of the balloon 200; the indicating capsule body is arranged between the filling and discharging thin tube 320 and the filling and discharging connector 310 and is positioned outside the ostomy tube 100, the inner cavity of the indicating capsule body is respectively communicated with the tube cavities of the filling and discharging connector 310 and the filling and discharging thin tube 320, the outer contour dimension of the indicating capsule body is larger than the outer diameter of the filling and discharging thin tube 320, and the indicating capsule body is in a bulging shape when the saccule 200 is in a propping state and in a sunken shape when the saccule 200 is in a retracting state. The indication capsule plays an important role particularly when the fistulation tube 100 needs to be pulled out after the healing of an anastomotic stoma of a patient, a medical worker connects the charging and discharging connector 310 through an external device to pump out gas/liquid in the balloon 200, when the indication capsule is in a completely sunken shape, the balloon 200 can be judged to be restored to a retraction state, at the moment, the fistulation tube 100 can be pulled out, in the process, the indication capsule can provide visual reference for the medical worker so as to master the retraction state of the balloon 200, the working efficiency of the medical worker can be improved, more importantly, the fistulation tube 100 can be effectively prevented from being pulled out due to the fact that the balloon 200 is not completely restored to the retraction state, and damage to the patient is caused. In the daily use of the ostomy tube 100, the patient or medical staff can judge the filling state of the balloon 200 by touching and/or observing the filling state of the indicating balloon, and if the filling state of the indicating balloon is found to change, the filling state of the balloon 200 can be adjusted by filling/discharging liquid/gas into/from the balloon 200.

Of course, if the balloon 200 is retracted during use, the determination by observing/touching the filling state of the indication balloon is not necessarily accurate, but can provide a certain reference value for medical staff and patients. In order to further improve the accuracy of monitoring the filling state of the balloon 200, a pressure monitoring device may be installed on the inner/outer surface of the balloon 200, and a device connected with the pressure monitoring device and allowing a monitoring result to be read is arranged outside the patient body, so that a medical worker or the patient can know the state of the balloon 200 more accurately, and then intervene in time when the state of the balloon 200 changes, so as to ensure that the balloon 200 works in a better state during use.

The indicating bladders are arranged in correspondence with the receptacles 500; referring to fig. 1, 3 and 5, the container 500 is provided with a C-shaped hollow portion 530, the C-shaped hollow portion 530 is disposed corresponding to the indicating capsule, the indicating capsule is completely/partially exposed in the C-shaped hollow portion 530 in the swelling state, and the shape and the structure of the C-shaped hollow portion 530 are adapted to the space range required by the human finger to press and touch the indicating capsule. By arranging the indicating balloon correspondingly to the C-shaped vacant part 530 on the receptacle 500 so as to arrange the indicating balloon, the indicating balloon can be prevented from being pressed by an external structure by mistake and affecting the normal use of the balloon 200; in addition, the shape and the structure of the C-shaped hollow part 530 are set to be adapted to the space range required by the human finger to press and touch the indicating balloon, so that the medical staff can conveniently touch and/or press the indicating balloon, know the state of the indicating balloon and further judge the working state of the balloon 200.

Referring to fig. 1, 3 and 5, a physician typically holds the shaft of the fistula 100 by hand and performs the palpation and/or pressing operation with the thumb while touching and/or pressing the indicating balloon, so that the shape and configuration of the C-shaped opening 530 is adapted to the operation space required for the thumb of the hand to perform the palpation and/or pressing operation.

Preferably, the C-shaped void 530 is a V-shaped or circular arc-shaped gap, as shown in fig. 1, 3 and 5.

If the fistula tract 100 is provided with the inflation/deflation joint 310 and the irrigation joint 410 at the same time, when the irrigation operation is performed, an external irrigation device may be mistakenly connected to the inflation/deflation joint 310, so that the irrigation liquid is mistakenly inflated into the balloon 200, which may cause the state of the balloon 200 to change. In order to prevent this problem, referring to fig. 1 to 3 and fig. 5, the present embodiment further provides a protective cover 540, the protective cover 540 is movably mounted on the ostomy tube 100, and the protective cover 540 and the charging and discharging connector 310 form a detachable assembly connection for covering/blocking the interface of the charging and discharging connector 310. By providing the protective cover 540, the medical staff and the patient can also be helped to identify the position of the charging and discharging connector 310 so as to avoid misuse. The protective cover 540 can protect the filling interface and also avoid mis-filling the balloon 200 after surgery to prevent ischemic necrosis of the intestinal wall caused by mis-filling the balloon 200.

Under the condition that the accommodating part 500 is made of hard materials, in an operation, the end A of the fistulization tube 100 needs to be inserted into the intestinal canal after penetrating through the abdominal wall of a patient, once a medical worker makes a mistake in the operation, the end A of the fistulization tube 100 is inserted into the intestinal canal of the patient, an incision matched with the outer contour of the accommodating part 500 needs to be formed in the abdominal wall of the patient, so that the end B of the fistulization tube 100 penetrates out from the inner side of the abdominal wall of the patient to the outer side until the accommodating part 500 is moved to the outer side of the abdominal wall, and therefore the abdominal wall of the patient needs to be provided with a large incision, the postoperative recovery period is prolonged, and the risk of postoperative infection is increased. In order to solve the problem, the embodiment of the present application provides the following preferred solutions: referring to fig. 8, the receiving member 500 is made of a soft deformable material. Because the containing part 500 is made of soft deformable materials, after the above errors occur in the operation, the containing part 500 can also conveniently penetrate out from a smaller incision on the abdominal wall, so that a larger incision is avoided being arranged on the abdominal wall of a patient, the postoperative recovery is facilitated, and the postoperative infection risk is reduced.

Specifically, the receiving member 500 may be made of a silicone material meeting medical standards.

In the case that the storage member 500 is made of hard material, the charging and discharging connector 310 and the flushing connector 410 are sometimes fixedly assembled with the storage member 500, that is, once the assembly is completed, the two connectors cannot be detached or moved, so that the use of the charging and discharging connector 310 and the flushing connector 410 restricts the external equipment, and the range of the equipment which can be adapted to the external equipment is reduced. For example, the external device is usually a syringe commonly used in the medical field, and the filling and discharging connector 310 can be connected to the syringe to fill/discharge liquid/gas into/from the balloon 200 through the syringe, but once the posture of the filling and discharging connector 310 is fixed, a syringe with a specific size and a specific structure is required to be plugged with the interface of the filling and discharging connector 310, otherwise, the plugging may be weak or even impossible. In this regard, in this embodiment, referring to fig. 8, the a cavity 510 and the B cavity 520 are detachably assembled and connected to the charging and discharging connector 310 and the flushing connector 410, respectively. During use, the fill and drain connector 310 and the flush connector 410 can be removed from the receptacle 500 to change the position of the connectors so that the connectors can be securely connected to the connection ends of the external device. In addition, when medical personnel inserted the intestines tube earlier with the end A of fistulization pipe 100 in the operation by mistake, when needing to wear out patient's stomach wall with the end B of fistulization pipe 100 from inside to outside, can pull down two joints from receiving member 500 earlier to receiving member 500 can produce great deformation volume and adapt to the less incision of seting up on the stomach wall, make receiving member 500 pass through smoothly, and two joint itself volumes are less, pass the incision comparatively easily.

Of course, in the case that the receptacle 500 is made of a hard material, the charging and discharging connector 310 and the flushing connector 410 may be detachably assembled with the receptacle 500.

Specifically, referring to fig. 8, the a-hollow 510 and the B-hollow 520 are formed by a groove a and a groove B disposed on the receiving member 500, and the groove a and the groove B are respectively snap-fitted with the charging and discharging connector 310 and the flushing connector 410. When the connector is used, the connector is taken out, and the connector is pressed and clamped into the corresponding groove after use, so that the connector can be stored.

Referring to fig. 1-8, the a-void 510 and the B-void 520 are preferably disposed on opposite sides of the ostomy tube 100, so as to prevent the two connectors from interfering with each other during use and facilitate differentiation.

In order to further improve the recognition of the charging and discharging joint 310 and the flushing joint 410, the present embodiment provides the following preferable solutions: the containing piece 500 is further provided with an A mark and a B mark, the A mark and the B mark are respectively arranged corresponding to the A vacancy part 510 and the B vacancy part 520, the A mark is used for indicating the assembling position of the charging and discharging joint 310 on the containing piece 500, and the B mark is used for indicating the assembling position of the flushing joint 410 on the containing piece 500.

The storage part 500 is a housing structure, the mark a and the mark B may be characters, patterns, labels, nameplates, etc. engraved on the housing, and the characters, patterns, etc. may be etched concave structures or embossed convex structures.

Referring to fig. 1 to 3, 5, 7, 8, and 12 to 16, the end B of the fistula 100 is further provided with an a-joint 610, which is a straight-through joint, the input end of the a-joint 610 is connected to the end B of the fistula 100, and the inner diameter of the output end of the a-joint 610 is equal to or larger than the inner diameter of the fistula 100. The output end of the a-joint 610 can be connected with the existing negative pressure drainage device, and can also be connected with the negative pressure drainage device through accessories such as a pagoda joint, an extension tube 700 and the like, so as to assist in enhancing the drainage efficiency of the fistulation tube 100 to intestinal contents. The reason why the inner diameter of the output end of the a-joint 610 is set to be greater than or equal to the inner diameter of the ostomy tube 100 is to ensure that intestinal contents drained in the ostomy tube 100 can pass through the output end of the a-joint 610 smoothly with a large flow rate, i.e., the a-joint 610 can maintain the passing property in conformity with the ostomy tube 100.

The input end of the a-joint 610 is preferably sleeved outside the ostomy tube 100 so as to ensure that the flux of the input end and the flux of the output end of the a-joint 610 are consistent with the ostomy tube 100, thereby preventing intestinal contents from being blocked at the ostomy tube 100 and the a-joint 610.

The length of the fistulation tube 100 is usually not very long, while the negative pressure drainage device usually needs to be connected to the fistulation tube 100 all the time, and if the length of the pipe on the negative pressure drainage device is not proper, the storage of the negative pressure drainage device is inconvenient, and the use of the fistulation tube 100 is more convenient and extensive. In this embodiment, referring to fig. 1 to 3, fig. 5, fig. 7, fig. 8, and fig. 12 to fig. 16, the ostomy appliance further comprises a B-joint 620 adapted to the a-joint 610, the B-joint 620 is also a through-type joint, an input end of the B-joint 620 is detachably assembled to an output end of the a-joint 610, an output end of the B-joint 620 is adapted to be connected to the external extension tube 700, and an inner diameter of the input end of the B-joint 620 is consistent with an inner diameter of the ostomy tube 100. By adopting the scheme, the A connector 610 and the B connector 620 can keep the trafficability characteristic consistent with the lumen of the fistulization tube 100, and are connected with the extension tube 700 through the B connector 620, so that the situation that the distance between the negative pressure drainage device and a patient is different can be adapted, and of course, the external extension tube 700 can be cut according to the actual requirement, so that the length of the extension tube 700 is proper. The extension tube 700 may be connected to the negative pressure drainage device through an existing fitting.

Wherein, the input end of the A joint 610 is fixedly connected with the fistulization tube 100, the output end of the B joint 620 is fixedly connected with the extension tube 700, and the specific fixing mode can adopt an adhesive mode.

Due to the detachable connection mode of the a connector 610 and the B connector 620, the connection can be disassembled according to the need, for example, sometimes the extension tube 700 is not needed, and when the negative pressure drainage device is directly connected with the a connector 610, the B connector 620 and the extension tube 700 are not assembled, or the assembled B connector 620 and the extension tube 700 are disassembled.

Specifically, referring to fig. 12 to 16, the inner bore of the a-joint 610 includes a hole section 611 and a hole section 612 of a1 and a hole section 612 of a2, which are arranged along the same direction, the hole sections 611 and a2 of a1 and a hole section 612 of a1 are respectively arranged corresponding to the input end and the output end of the a-joint 610, the hole section 611 of a1 is sleeved on the outer wall of the B-end of the fistulization tube 100, the hole section 612 of a2 is detachably sleeved outside the input end of the B-joint 620, the hole diameter of the hole section 611 of a1 is larger than that of the hole section 612 of a2, and a step formed at the junction of the hole section 611 of a1 and the hole section 612 of a2 on the inner wall of the a-joint 610 is used for limiting the insertion depth of the fistulization tube 100.

The inner diameter of the ostomy tube 100 is smaller than the diameter of the a2 hole section 612, and after the ostomy tube 100 is assembled with the a-joint 610, a stepped structure is formed between the ostomy tube 100 and the inner wall of the a2 hole section 612 for limiting the insertion depth of the B-joint 620, see fig. 12-16.

The A1 hole section 611 and the fistulization tube 100 are fixed by gluing, and a glue distribution groove for uniformly distributing glue is arranged on the inner wall of the A1 hole section 611. The glue solution is uniformly distributed in the glue distribution groove, so that the joint of the A connector 610 and the fistulation tube is firmer after the glue solution is solidified, and the sealing and anti-seepage effects can be improved.

In order to enable the glue solution to be uniformly distributed at the joint of the fistulization tube 100 and the A joint 610, after the glue solution is solidified, the A joint 610 and the fistulization tube 100 can be higher in connection strength and better in sealing performance. In this regard, the preferred embodiments provided in this example are: as shown in fig. 13 and 14, the glue dispensing groove comprises an annular groove 611a and a vertical groove 611b, which are arranged along the length direction of the a-joint 610, wherein the annular groove 611a is arranged close to the a2 hole section 612, the annular grooves 611a are arranged at intervals along the length direction of the a-joint 610, the length direction of the vertical groove 611b is consistent with the length direction of the a-joint 610, and the vertical grooves 611b are arranged at intervals along the circumference direction of the a1 hole section 611; the annular groove 611a is used for uniformly distributing and storing glue solution along the circumferential direction, and the vertical groove 611b is used for uniformly distributing and storing glue solution along the length direction of the a-joint 610.

Of course, it will be understood by those skilled in the art that the annular groove 611a and the vertical groove 611B can be disposed on the outer wall of the end B of the fistula 100 as long as the above purpose is achieved.

In practical implementation, if the glue solution in the annular groove 611a is too much, the glue solution may overflow to the aperture section a2 during the assembly process, and after the glue solution is solidified, the inner wall of the aperture section a2 of the a-junction 610 is uneven. In contrast, as shown in fig. 13 and 14, one end of the vertical groove 611b extends into the grooves of part/all of the annular groove 611a along the groove length direction, so that excessive glue in the annular groove 611a can overflow out of the a-joint 610 along the vertical groove 611b in the direction away from the a2 hole segment 612 during the process of assembling the fistula 100 and the a-joint 610, and the overflow amount of the glue in the a2 hole segment 612 can be reduced, thereby ensuring the structural integrity of the inner wall of the a2 hole segment 612.

In order to ensure the sealing performance between the a-joint 610 and the ostomy 100, it is preferable that one end of the vertical groove 611b extends into the groove of the partial annular groove 611a along the groove length direction thereof, where the partial annular groove 611a is a part of the annular grooves 611a of all the annular grooves 611a facing away from the a2 hole section 612, and the rest of the annular grooves 611a close to the a2 hole section 612 and the vertical groove 611b are arranged in a separated manner, as shown in fig. 13 and 14.

The material from which the air-bag is made may be flexible only, but not necessarily elastic, and in order to achieve deployment of the air-bag into the inflated condition, the outer bag wall 210 preferably has a fold when the air-bag is in the retracted, avoidable condition, the fold being progressively deployed as the air-bag switches from the retracted, avoidable condition to the inflated condition.

The bladder is also preferably made of a soft elastomeric material. In this way, the filling degree of the air bag can be adjusted according to different use requirements, so that the air bag can be used on different patients, and the expected effect of blocking downstream movement of intestinal contents is achieved.

Of course, the amount of deformation may not be uniform at all locations on the balloon, as long as it is ensured that the intestinal contents are blocked after the balloon is inflated as a whole, and the transitional coupling portion 240 of the balloon is allowed to bulge out of the end surface of the tube of the fistula to prevent a dead space between the end surface of the tube of the fistula and the balloon from being created for storing the intestinal contents. In this regard, in the embodiment of the present application, the deformation amount of the transitional connecting portion 240 of the balloon is preferably greater than the deformation amount of the remaining portions of the balloon under the same pressure in the balloon lumen.
