Description

Novel head-mounted infusion device

Technical Field

The invention relates to the technical field of medical treatment, in particular to a novel head-mounted infusion device.

Background

When intravenous infusion, the liquid medicine which is required to be infused by a patient in the day is usually prepared and packaged in a plurality of infusion bags/bottles at one time and hung on the hooks of the infusion support, and in the infusion process of the next bottle/bag of liquid medicine after the infusion of the liquid medicine is finished, the patient is usually informed of the replacement of medical staff, so that the burden of the medical staff is increased. In addition, the infusion bottle or the infusion bag needs to be supported by the infusion support, so that the patient is inconvenient to walk, go to the toilet and other activities. Meanwhile, when the existing intravenous transfusion is carried out, the patients in the same transfusion chamber are closely contacted, and cross infection is easy to occur among the patients, so that the spreading risk of diseases is increased. In addition, a plurality of patients receive infusion treatment in a fixed space place at the same time, the problems of noise, crowding of personnel and the like are easy to occur, uncomfortable feeling and psychological pressure are brought to the patients, and recovery time of the patients can be increased.

Some prior art infusion devices are known that are wearable or removable so that the patient can move relatively freely without having to hold an infusion bottle or bag. For example, the infusion device can be worn on the head, but the infusion device which can be worn on the head in the prior art can only carry one bottle/bag of liquid medicine, does not fundamentally solve the technical problems of free movement, liberation of hands, reduction of liquid replacement in the infusion process and the like, and is not friendly to patients and medical staff.

In addition, the infusion container of the head-mounted infusion device is usually worn on the head of a patient, and compared with the supporting height of the infusion bag by the traditional infusion support, the supporting height of the head-mounted infusion container is low, and the obtained gravitational potential energy is smaller than that of the infusion bag supported by the traditional infusion support. Therefore, in the latter half of infusion, particularly when the infusion liquid medicine is rapidly ended, the interior is easy to generate folds or uneven caused by the collapse of the infusion container, so that the residual liquid medicine is likely to be deposited at the bottom of the infusion container, the flowing kinetic energy is insufficient, the infusion flow rate is reduced, even the situation of no flowing occurs, and the liquid medicine is also wasted due to the stagnation of the liquid medicine in the collapsed infusion container, which is unfavorable for disease treatment.

The four container monomers 7 are all annular closed, the inside of the container monomers is hollow, the four container monomers 7 are provided with a liquid medicine inlet 8 and a liquid medicine outlet 9, the liquid medicine inlet 8 is used for adding liquid medicine into the annular closed container monomers 7, and the liquid medicine inlet 8 is provided with a first sealing element capable of self sealing, namely a sealing plug or a sealing valve. The liquid medicine outlet 9 includes a depressed portion gradually sloping smoothly from the lowermost inner wall of the ring-shaped closed container unit 7 so as to form a low point like a funnel, so that the liquid medicine in the ring-shaped closed container unit 6 can be gathered centering on the depressed portion.

Clinically, the total amount of continuous normal infusion that an adult infusion patient experiences from insertion to withdrawal within a day or 12 hours is generally 2500ml or less, usually 800ml to 2000ml, and most usually 1000ml to 1500 ml. Therefore, the specific number of the head-mounted infusion containers 1 is preferably composed of 2 to 8 annular closed container monomers 7, more preferably 2 to 6 annular closed container monomers 7. The volume of the single annular closed container unit 7 is set to be 100ml to 600ml, for example, 100ml, 150ml, 200ml, 225ml, 250ml, 300ml, 325ml, 350ml, 400ml, 425ml, 450ml, 500ml, 550ml, 600ml, etc. The volume of each annular closed container unit 7 may be the same or different or only partially the same for a complete head mounted infusion container 1. The total volume of the head-mounted infusion container of the present application is preferably 600ml to 2600ml, more preferably 800ml to 2200ml.

In the application, each liquid medicine outlet 9 is connected with a transfusion tube, the transfusion tube stretches into the control box 6, the transfusion tube stretches out of the control box 6 after being regulated and controlled by the control box 6, and the transfusion tube is communicated with the upper transfusion hard tube 2 from the stretching end in the control box 6. The infusion tube comprises an infusion branch tube 101 and an infusion main tube 102, one end of each infusion branch tube 101 is respectively connected with each liquid medicine outlet 9 on each container unit 7, the other end of each infusion branch tube is connected with the infusion main tube 102 in parallel, namely, the infusion branch tubes 101 are arranged in parallel along the vertical direction, liquid medicine in each container unit 7 flows into the infusion main tube 102 from each infusion branch tube 101, and the liquid medicine output end of the infusion main tube 102 is connected with the upper infusion hard tube 2 in series. The upper end of the upper infusion hard tube 2 is connected with an infusion main pipe 102 extending out of the control box 6 of the head-mounted infusion container 1, or is directly connected with a liquid medicine outlet 8 of a container monomer 7 of the head-mounted infusion container 1, and the lower end of the upper infusion hard tube 2 is connected with the drip cup 3.

With respect to the drip cup 3, in order to find a proper balance between the flow of the liquid medicine and the prevention of the back blood, the drip cup 3 should have a proper reasonable height, and in the present application, the height of the drip cup 3 ("height of the drip cup" may be defined as the height of the uppermost end (or lowermost end) of the drip cup 3 with respect to the ground, or the height of the center of the drip cup 3 with respect to the ground) is not lower than the height of the heart of the human body, or not lower than the height of the needle insertion position of the arm when the patient stands, and the upper limit of the height of the drip cup 3 is not higher than the height of the shoulder of the human body, or not higher than the center height of the neck of the human body. In the present application, the height of the drip cup 3 is preferably set between the height of the heart of the human body and the height of the shoulders of the human body.

The upper hard infusion tube 2 of the present application is entirely made of a hard material such as hard plastic, metal, or the like. As shown in fig. 1, the upper infusion tube 2 comprises a curved section which is inclined downwards when worn and a vertical section which is connected with the drip cup 3. The upper infusion hard tube 2 with the structural design can vertically hang the drip cup 3 so that infusion liquid medicine can drip from the drip cup 3, meanwhile, the upper infusion hard tube 2 with the hard structure is convenient to shape, for example, the upper infusion hard tube 2 with the hard structure can be arranged to extend approximately parallel to the shoulder direction of a human body, and thus the drip cup 3 and the lower infusion hose 4 connected with the upper infusion hard tube 2 with the hard structure can not obstruct the line of sight of an infusion patient and can not obstruct the two-hand operation of the infusion patient. Therefore, in the present application, as shown in fig. 1, the rigid upper rigid infusion tube 2 is inclined downward with respect to the head-mounted infusion container 1 and extends parallel to the shoulder direction of the human body when worn, and the projection distance of the upper rigid infusion tube 2 in the shoulder direction of the human body is set so as not to exceed the width of the single-sided shoulder of the human body.

Since the liquid medicine outlet 9 of each container unit 7 is connected with the transfusion main pipe 102 through the transfusion branch pipe 101, the end of the transfusion main pipe 102 can be provided with a transfusion main outlet valve 103, and the transfusion main outlet valve 103 is provided with a second sealing element which can self seal, namely a sealing plug or a sealing valve. The transfusion main pipe 102 is connected with the upper transfusion hard tube 2 through the transfusion main outlet valve 103, namely the head-wearing transfusion container 1 can be manufactured separately from a transfusion device pipeline comprising the upper transfusion hard tube 2, the drip cup 3, the transfusion needle 5 and the like, and the two parts are connected during transfusion. The infusion main 103 can also be directly and integrally connected with the upper infusion hard tube 2 during manufacturing, namely, the head-wearing infusion container 1 and the infusion device pipelines comprising the upper infusion hard tube 2, the drip cup 3, the infusion needle 5 and the like are integrally manufactured and packaged in an aseptic manner, and when in use, the infusion main is directly opened and added with liquid medicine after being infused.

The control box 6 is arranged at the bottom of the container monomer 7 at the bottommost layer, part of the pipe body of each infusion branch pipe 101 and the infusion main pipe 102 are arranged in the control box 6, an air inlet pipe 104 is arranged at the position, close to the liquid medicine outlet 7, of each infusion branch pipe 101, and a first speed regulating device 105 for flow interception and/or flow speed control is arranged on each infusion branch pipe 101. The infusion branch pipe 101, the first speed regulating device 105 and the infusion main pipe 102 are integrally arranged on the control box 6 so as to control the infusion condition of each container unit 7. The transfusion main pipe 102 is connected with a lower transfusion hose 4, the end of the lower transfusion hose 4 is connected with a transfusion needle 5, and the lower transfusion hose 4 is also provided with a second speed regulating device 41, a filter 42 and other parts. The control box 6 may include a box body and a cover body (not shown in the figure) hinged to the box body, and a medical staff or an infusion patient may open the cover body to control the first speed regulating device 105, so as to regulate the infusion flow rate of the corresponding infusion branch pipe 101 or shut down the corresponding infusion branch pipe 101, and after the setting, the cover body may be closed, so that the cover body plays a role in protecting and preventing dust on each component in the box body.

Referring to fig. 2, a flexible membrane 11 is disposed in at least one annular closed container unit 7 of the head-mounted infusion container 1, the flexible membrane 11 divides an internal cavity of the container unit 7 into a gas chamber 111 and a liquid medicine chamber 112, while the container unit 7 of the embodiment is divided into an upper independent chamber and a lower independent chamber by the flexible membrane 1, namely, the lower chamber is the liquid medicine chamber 112 for containing liquid medicine, and the upper chamber is the gas chamber 111 for filling inflatable gas. The flexible film 11 may have a certain elasticity or may not have elasticity at all. When not filled with the liquid medicine, the flexible film 11 has a certain redundancy in the interior of the container monomer 7, and when filled with the liquid medicine, the flexible film 11 has a certain redundancy under the extrusion of the liquid medicine in the liquid medicine chamber 112, and the redundancy enables the flexible film 11 to be fully unfolded to be attached to the upper cavity wall of the gas chamber 111 under the extrusion of the liquid medicine, namely, the existence of the flexible film 11 hardly affects the volume of the container monomer 7 or has a small or negligible effect.

The gas chambers 111 in the respective container units 7 are connected to each other by pipes (not shown). The head-mounted infusion container 1 is provided with an inflation valve 113 for inflating each of the gas chambers 111, and since each of the gas chambers 111 is communicated with each other, only one inflation valve 113 is required to inflate all of the communicated gas chambers 111. The inflation valve 113 is detachably connected to a manually-depressible inflation bladder 114. In the middle and later period of transfusion, if the dropping speed is slower, or the transfusion is near to the end, because the transfusion container monomer 7 collapses after the liquid medicine is reduced, part of the liquid medicine is deposited in the folds of the collapsed container monomer 7 and cannot normally flow, at the moment, a patient or a attendant can manually press the inflating air bag 114 to inflate the gas chamber 111 of the container monomer, on one hand, the collapsed container monomer 7 can be inflated, and the inner wall of the container monomer 7 becomes smooth, so that the liquid medicine can flow. On the other hand, by manually inflating, the internal pressure of the container unit 7 can be increased, and the flow of the chemical liquid to the outlet can be promoted. Although the gas chambers 111 of the container units 7 communicate with each other, when the gas is inflated by the inflation valve 113, only the collapsed container unit 7 is squeezed and inflated, and the container unit 7 for which the chemical solution is not yet infused is not inflated, and the chemical solution outlet 9 of the container unit 7 is not opened, so that the inflation gas is not affected. The inflation valve 113 is also provided with a pressure release valve. The head-mounted infusion container 1 of the application is placed on the head of an infusion patient or an infusion attendant during infusion, and the overall height of the head-mounted infusion container 1 is lower than that of an infusion bottle/bag supported by a conventional infusion support. By arranging the inflation valve 113 and the inflation air bag 114, on one hand, the pressure of the collapsed container is increased, so that the kinetic energy of the liquid medicine is increased, and on the other hand, the inner wall of the collapsed container becomes smooth after inflation and expansion, so that the flow of the liquid medicine is facilitated. The defects that the power potential energy of the head-mounted infusion container 1 is smaller than that of an infusion bag supported by a traditional infusion support, residual liquid medicine is easy to pool, the infusion flow rate is low and the like can be overcome. Meanwhile, compared with the traditional transfusion in which transfusion liquid is contained through a transfusion bottle/bag, the improved head-mounted transfusion device has the advantages that the total continuous normal transfusion amount of a transfusion patient from needle insertion to needle withdrawal in one day or 12 hours is respectively contained in each container monomer 7 in the head-mounted transfusion container 1 according to transfusion requirements, so that the transfusion patient can freely move during transfusion. Not only solves the defects of crowded personnel, no ventilation in the infusion room and easy cross infection among infusion patients in the traditional infusion room, but also liberates the limbs of the patients, so that the patients can freely and conveniently go to the toilet, walk and the like, for example, can move to the outdoor or the places where the personnel are not crowded for infusion, can do some easy things which are beneficial to rehabilitation or boring time while doing infusion, for example, play mobile phones, playing cards, peeling melon seeds and the like.

Embodiment two:

The head-mounted infusion device can also be an automatic head-mounted infusion device capable of being controlled remotely and intelligently, and the main difference between the embodiment and the first embodiment is that the whole infusion process is controlled automatically and intelligently. Referring to fig. 3, the head-mounted infusion container 1 of the automatic head-mounted infusion device is also composed of four container units 7 which are annularly closed and hollow in the interior and are stacked up and down. Each container monomer 7 is provided with a liquid medicine inlet 8 and a liquid medicine outlet 9, the liquid medicine inlet 8 is used for adding liquid medicine into the container monomer 7, the liquid medicine outlets 9 of each container monomer 7 are connected with a transfusion main pipe 102 through a transfusion branch pipe 101, the tail end of the transfusion main pipe 102 can be provided with a transfusion main outlet valve 103, and the transfusion main outlet valve 103 is provided with a sealing plug or a sealing valve capable of self sealing. The transfusion main pipe 102 is connected with the upper transfusion hard tube 2 through the transfusion main outlet valve 103, namely the head-wearing transfusion container 1 can be manufactured separately from a transfusion device pipeline comprising the upper transfusion hard tube 2, the drip cup 3, the transfusion needle 5 and the like, and the two parts are connected during transfusion. The infusion main pipe 102 can also be directly and integrally connected with the upper infusion hard tube 2 during manufacturing, namely, the head-wearing infusion container 1 and the infusion device pipelines comprising the upper infusion hard tube 2, the drip cup 3, the infusion needle 5 and the like are integrally manufactured and packaged in an aseptic manner, and when in use, the infusion can be performed after the packaging is directly opened and the liquid medicine is added.

The control box 6 is also installed at the bottom of the container monomer 7 at the bottommost layer, a plurality of infusion branch pipes 101 which are respectively connected with the liquid medicine outlets of the corresponding container monomers 7 are arranged in the control box 6, and an air inlet pipe 104, an infusion pipe monitoring piece 106 and an electromagnetic valve 107 are sequentially arranged on each infusion branch pipe 101 downwards from a position close to the liquid medicine outlet 7. The infusion tube monitoring piece 106 is used for monitoring whether the liquid in the infusion branch pipe 101 exists in real time, and the infusion tube monitoring piece 106 can be an infrared photoelectric sensor, a capacitance sensor and the like. The infusion tube monitoring piece 106 and the electromagnetic valve 107 are respectively and electrically connected with the controller 12 in a wired or wireless mode. The infusion tube monitoring piece 106 transmits real-time monitoring information of the liquid in the infusion branch tube 101 to the controller 12, and the controller 12 controls the opening and closing of the electromagnetic valve 107 according to the uploaded monitoring information. The control box 6 is also provided with a control keyboard or a touch screen for medical staff or patients to input corresponding parameters.

Before starting infusion, medical staff fills the corresponding annular container monomers 7 with liquid medicine through the liquid medicine inlets 8, for example, 900ml of liquid medicine is needed to be infused into a patient once in the same day, namely, liquid medicine A (100 ml), liquid medicine B (400 ml), liquid medicine C (200 ml) and liquid medicine D (200 ml), and the infusion sequence is A- > B- > C- > D. Then, the medical staff fills the liquid medicine in such a case that the liquid medicine B is filled in the lowermost annular container cell 7 (which corresponds to the first infusion branch pipe 101), the liquid medicine C is filled in the second annular container cell 7 (which corresponds to the second infusion branch pipe 101) from the bottom up, the liquid medicine D is filled in the third annular container cell 7 (which corresponds to the third infusion branch pipe 101) from the bottom up, and the liquid medicine A is filled in the uppermost fourth annular container cell 7 (which corresponds to the fourth infusion branch pipe 101) (which is the lower and lower weight of the liquid medicine is filled in the lower and lower position). After the filling of the liquid medicine is completed, medical staff inputs corresponding parameters through a control keyboard or a touch screen to control all electromagnetic valves 107 to be opened, and the liquid medicine of the corresponding annular container monomers 7 flows from each infusion branch pipe 101 to the infusion main pipe 102 until all bubbles in the pipe are removed. After the bubbles are removed, each of the infusion branch pipes 101 and the infusion manifold 102 is filled with liquid, and the solenoid valve 107 on each of the infusion branch pipes 101 is closed under the control of the controller 12. When the infusion is started, the infusion tube monitoring piece 106 transmits real-time monitoring information of the liquid in the infusion branch tube 101 to the controller 12, and when the existence of the liquid in the infusion branch tube 101 is monitored and the preset time period is continued, the controller 12 automatically controls the electromagnetic valve 107 of the corresponding infusion branch tube 101 to be closed and simultaneously opens the electromagnetic valve 107 of the next infusion branch tube 101. For example, if the infusion tube monitoring member 106 monitors the presence or absence of the liquid in the first infusion branch tube 101 and still does not monitor the liquid for 5 seconds or 10 seconds, then the controller 12 automatically controls the electromagnetic valve 106 on the first infusion branch tube 101 to be closed, which indicates that the liquid medicine B of the first infusion branch tube 101 may have been emptied from the corresponding annular container unit 7. At the same time, the controller 12 controls the solenoid valve 106 on the second infusion branch pipe 101 to open, and starts infusion of the drug solution C.

The control box 6 is also provided with a battery (not shown) for supplying power to the infusion tube monitoring member 106, the electromagnetic valve 107 and the controller 12, and the battery is a rechargeable battery which can be charged in a wired or wireless manner. In order to reduce the weight of the head-mounted infusion container 1 as much as possible, the battery and the controller 12 are not generally disposed in the control box 6, but are separately disposed in another auxiliary control box (not shown in the figure), and the auxiliary control box is electrically connected with the control box 6, and is designed as an independent structure and can be worn on the shoulder, waist and other parts of the human body through a lacing, an elastic belt, a magic tape, a sticking buckle belt and the like.

Similarly, the inside of at least one annular closed container unit 7 of the head-mounted infusion container 1 may be provided with a flexible membrane 11, the flexible membrane 11 may have various arrangements inside the container unit 7, for example, the container unit 7 is divided into two independent chambers up and down or left and right by the flexible membrane 11, while the container unit 7 of the present embodiment is divided into two independent chambers left and right by the flexible membrane 1, that is, the left chamber is a liquid medicine chamber 112 for containing liquid medicine, the right chamber is a gas chamber 111 for filling inflatable gas, and the gas chambers 111 for filling inflatable gas in each container unit 7 are all communicated with each other by pipes (not shown in the figure). The flexible film 11 may have a certain elasticity or may not have elasticity at all. When the chemical solution is not filled, the flexible film 11 has a certain redundancy in the inside of the container unit 7. When filling with the medical fluid, the flexible membrane 11 has a certain redundancy under the extrusion of the medical fluid in the medical fluid chamber 112, which enables the flexible membrane 11 to be fully unfolded under the extrusion of the medical fluid to be attached to the upper cavity wall of the gas chamber 111, i.e. the presence of the flexible membrane 11 has little or negligible influence on the volume of the annular closed container unit 7.

The head-mounted infusion container 1 is provided with an inflation valve 113 for inflating the gas chamber 111, the inflation valve 113 is detachably connected with the automatic inflation device 13, and the inflation valve 113 is also provided with a pressure release valve. The automatic inflating device 13 is also provided in the above-described auxiliary control box (not shown in the drawings) together with the above-described battery, controller 12, etc., in order not to additionally increase the weight of the head-mounted infusion container 1. And the auxiliary control box is worn on the shoulder, waist and other parts of the human body, so that the user can easily operate and control the auxiliary control box. The automatic inflator 13 includes an inflation line 131 for detachably connecting with the inflation valve 113, a micro-pump 132, and an inflation controller 133. The micro-inflator 132 is connected with the inflation controller 133 by wire or wirelessly, and the micro-inflator 132 and the inflation controller 133 are electrically connected with the batteries. The inflation controller 133 is wired or wirelessly connected to the controller 12. The medical professional or user may set the corresponding conditions that trigger the micro-pump 132 to operate, for example, when no fluid is first detected in the manifold 101, or when no fluid is detected in the manifold 101 for a continuous period of 3 seconds (this period), the controller 12 controls the micro-pump 132 to operate, and then the micro-pump 132 may be stopped after a predetermined period of time, e.g., 1, 2, 3 minutes, at a predetermined rate, or after the micro-pump 132 is inflated to a predetermined pressure (a pressure sensor may be provided at the end of the inflation valve 113 near the reservoir cell 7).
