Description

Lock Type Catheter Fixation Device {Lock Type Catheter Fixation Device}

The present invention relates to a lock-type catheter fixing device, and more particularly, is convenient to use, primarily fixes a catheter inserted into the fixing part through the structure of the fixing part, pressurizes the fixing part with a predetermined pressure, It relates to a lock-type catheter fixing device capable of rapidly and stably maximizing the fixing force of a catheter by fixing it secondarily through a first band portion and a second band portion that surround it.

In general, a catheter is inserted into a part of a patient's body to measure the discharge of internal fluids from body cavities (pleural cavity, peritoneal cavity), digestive tract, bladder, etc., or a drainage device such as a medical tube used for hemodialysis and drug infusion. am. These catheters are variously classified into A-V Fistula (Ateriovenous Fistula) arteriovenous fistulas, venous tubes, peritoneal dialysis catheters, etc. for the purpose of dialysis of blood.

Conventionally, in order to fix the catheter inserted into a patient's body part, bandages are attached to various parts of the catheter to fix the catheter to the patient's body.

However, even if the catheter having a circular cross-section is fixed using a bandage, problems such as shaking in the fixed position according to the movement of the patient and the bandage falling off the skin occur.

Accordingly, there is a problem that the catheter inserted into the body of the patient is separated from the body or a wound is generated in the corresponding part due to movement. In order to prevent this, when a bandage is periodically replaced, or in the case of a patient whose skin is sensitive, problems such as scarring occur on the skin due to frequent replacement of the bandage.

In addition, remnants of the sticky tape remain on the outer wall of the catheter, which is a potential source of infection.

In order to solve this problem, various catheter fixation devices have been developed. In one embodiment, a Velcro-type catheter fixation device or lock-type fixation device has been developed.

However, in the case of the Velcro type, while it is convenient to fix the tube, there is a problem in that foreign substances such as dust are attached to the Velcro and the adhesive force is reduced when the Velcro is repeatedly separated and fastened, such as exchanging the tube due to the nature of the Velcro.

In addition, in the case of the lock-type fixation device, the fixation force is improved by using a fixation table made of plastic for stronger fixation, but there is a difficulty in fixing the tube, and the plastic material reduces the patient's wearing comfort, complaining of inconvenience, There is a problem that compatibility of catheters of various diameters is not easy.

As shown in FIGS. 1 to 4 , the lock-type catheter fixing device 10 may be composed of a fixing part 100, a first band part 200, a second band part 300, and an adhesive pad 400. there is.

The fixing part 100 is a device for fixing the placement position by fixing a drainage tube such as a medical tube or catheter 1000 to be inserted to suppress shaking. To this end, the fixing part 100 may be formed in a rod shape having a hollow interior so that the catheter 1000 can be inserted therein. At this time, the fixing part 100 is formed with an incision 130 having one side cut so that the catheter 1000 can be inserted. In the present invention, the front and rear are open, and the cutout 130 is formed on the upper surface, but it is shown as the center, but the cutout 130 may be formed on the side other than the upper surface. At this time, the material of the fixing part 100 is preferably made of an elastic material such as silicon.

In addition, in order to more strongly and stably fix the catheter 1000 of various diameters inserted through the incision 130, a first pressure protrusion 110 may protrude from one side of the inner circumferential surface of the fixing part 100. The first pressing protrusion 110 is formed to protrude inward from one side of the inner circumferential surface of the hollow fixing part 100 to press the outer circumferential surface of the catheter 1000 to more strongly suppress the movement of the catheter 1000. It is free even if it consists of

It may be formed in a columnar shape, preferably a cylindrical shape. At this time, in order to prevent the shape of the catheter 1000 from being deformed due to the first pressure protrusion 110, the catheter 1000 is stably fixed and at the same time made of a hollow structure to be flexibly changeable according to the diameter of the catheter 1000. It is good. That is, as shown in the drawing, the first pressing protrusion 110 protrudes to have an arc-shaped cross section along the longitudinal direction on one side of the inner circumferential surface of the fixing part, and the movable range of the protruding first pressing protrusion 110 is extended. To do this, a groove of a predetermined depth may be formed on one side of the inner circumferential surface of the fixing part 100 corresponding to the first pressing protrusion 110 . Accordingly, the first pressing protrusion 110 may be seen as a hollow pillar shape in which the groove is coupled. In the present invention, it is shown that the two first pressing protrusions 110 protrude at both inner sides of the fixing part 100, preferably at a position slightly higher than the center of the side, but this is only one embodiment, A first pressing protrusion 110 may be additionally provided on a bottom surface of the fixing part 100 facing the cutout 130 . In addition, it is obvious that a greater number of first pressing protrusions 110 may protrude depending on the usage mode.

As shown in FIGS. 4 to 7 , the first pressing protrusion 110 according to the second embodiment, unlike the first embodiment, along the longitudinal direction of the catheter 1000 inserted into the fixing part 100 It may be made of a thin rod-shaped structure with a predetermined thickness that protrudes long. At this time, the number of first pressing protrusions 110 can be set in various ways, but preferably a plurality of them are provided, and when a plurality of first pressing protrusions 110 are provided, they are radially spaced at equal intervals based on the center of the hollow part of the cutout 130. It is good to be provided. The first pressing protrusion 110 is preferably made of a material with relatively low strength compared to the catheter 1000 in order to prevent damage or deformation of the outer circumferential surface of the catheter 1000 to be pressed, preferably silicone. It is good that it is made of material.

In addition, depending on the usage mode, the first pressing protrusion 110, like the first or second embodiment, is not protruded from the inner circumferential surface of the fixing part 100, but covers the inner circumferential surface of the fixing part 100 as a whole. A pressing member such as a sponge may be provided.

A first adhesive surface 120 to which an adhesive is applied may be formed on one surface of the fixing part 100, preferably on the other outer surface opposite to the one surface on which the cutout 130 is formed. Although the first adhesive surface 120 is named in the present invention, it may mean an adhesive layer formed by applying an adhesive to one surface of the fixing part 100 . Accordingly, the fixing part 100 may be adhered to the user's skin or one side of the adhesive pad 400 . A release paper is additionally provided on the first adhesive surface 120 to prevent arbitrary adhesion. The first adhesive surface 120 is not formed according to the usage mode, and in this case, the fixing part 100 may be integrally formed with the adhesive pad 400 on one side of the adhesive pad 400 to be described later.

The first band unit 200 and the second band unit 300 protrude to one side of the outer circumferential surface of the fixing unit 100 with a predetermined length, and are provided with the protruding portion surrounding the outer circumferential surface of the fixing unit 100 to enable mutual fastening. It is a device that presses and fixes the government 100 with a predetermined force. At this time, it is preferable that the first band part 200 and the second band part 300 are made of an elastic material having a predetermined elasticity, preferably a silicone material, so as to smoothly cover the fixing part 100 . In addition, the first band unit 200 and the second band unit 300 are preferably formed integrally with the fixing unit 100 on one side of the fixing unit 100, and preferably made of the same material as the fixing unit 100. As long as this object can be achieved, the first band unit 200 and the second band unit 300 may be configured in any configuration. The configuration of each of the first band unit 200 and the second band unit 300 according to an embodiment will be described in more detail with reference to the drawings.

The first band part 200 is one side of the fixing part 100, preferably one side of the side adjacent to one side on which the incision 130 is formed, more preferably one side adjacent to the one side on which the incision 130 is formed and the incision A predetermined length protrudes from the corner portion where the other surface opposite to one surface on which 130 is formed is in contact. At this time, the length of the first band portion 200 is not limited, but is a length that can sufficiently cover at least one surface on which the incision 130 is formed, preferably the outer circumferential surface of the fixing portion 100 in order to flexibly cope with various situations. It is good to have a length corresponding to the diameter. In addition, the width of the first band portion 200 is preferably made of a band shape that is relatively thinner than the width of the side portion of the fixing portion 100, and in order to easily penetrate the coupling hole formed in the second band portion 300, It is preferable that the terminating part of the 1-band part 200 is formed in the form of a wedge whose width gradually decreases toward the terminating end. And at least one side, preferably both sides, of the first band unit 200 has a plurality of fixings along the longitudinal direction so as to act as a holding member so as not to be arbitrarily separated after passing through the coupling hole of the second band unit 300. A protrusion 210 is formed to protrude. The fixing protrusion 210 is formed with an inclined surface so that the width gradually widens from the outside to the inside, and the other surface of the inclined surface is formed perpendicular to the side surface of the first band unit 200 . That is, it is formed in a sawtooth shape to facilitate insertion into the through hole of the second band part 300, and after penetrating the fixing hole 310, the end of the vertical surface on both sides is longer than the width of the through hole so that the vertical surface can be caught in the through hole. The length of the difference is formed relatively long.

In addition, as shown in FIGS. 4 to 7, the upper surface of the first band part 200, that is, one surface facing the fixing part 100 when the first band part 200 surrounds the fixing part 100 is When covering the top part 100, it is inserted into the incision 130 of the fixing part 100 to fix the position of the catheter 1000 together with the first pressing protrusion 110 of the fixing part 100, or the catheter 1000 The second pressing protrusion 220, which serves to prevent separation through the cutout 130, is formed protrudingly. At this time, the protruding length of the second pressing protrusion 220 corresponds to the height of the cutout 130, that is, the distance between the outer diameter and the inner diameter of the fixing part 100 where the cutout 130 is formed, or is relatively long. It is good to be formed. The second pressing protrusions 220 are provided in plurality along the longitudinal direction of the first band part 200 so that they can be selectively used according to the diameter of the catheter 1000 . In the present invention, it is shown that the second pressing protrusion 2200 protrudes only in FIGS. 4 to 7 for the second embodiment, but this is only for displaying various embodiments, and the first band part according to the first embodiment It is obvious that the second pressing protrusion 220 may also be formed protruding from 200 .

The second band part 300 is provided on the other side of the fixing part 100 opposite to the first band part 200, surrounds the fixing part 100 together with the first band part 200, and is coupled with the first band part 200. It is a device that maintains the state of wrapping the fixing part 100. As long as this object can be achieved, the first band unit 200 may be configured in any structure. At this time, the width of the second band portion 300 is preferably made of a band shape formed relatively wider than the width of the first band portion 200 because the first band portion 200 must pass through.

At this time, a fixing hole 310 through which the first band part 200 is fixed is formed at one side of the center of the second band part 300 . The fixing hole 310 may be formed to correspond to the longitudinal cross-sectional shape of the first band part 200 . That is, since the longitudinal section of the first band part 200 according to the first embodiment is formed in a thin strip shape, the fixing hole 310 may also be formed in a corresponding strip shape. On the other hand, since the second pressing protrusion 220 protrudes from the longitudinal section of the first band part 200 according to the second embodiment, the fixing hole 310 also corresponds to the cross section from which the second pressing protrusion 220 protrudes. It is formed to have a T' shape. However, the width of the fixing hole 310 is larger than the longest part of the fixing protrusion 210 protruding from both sides of the first band portion 200 so that the fixing protrusion 210 of the penetrating first band portion 200 can be caught. Have a relatively short length. Even if the width of the fixing hole 310 is formed relatively shorter than the width of the first band part 200, the first band part 200 and the second band part 300 are made of a material having a certain elasticity, so that a certain pressure or more When the first band part 200 is inserted by force, the first band part 200 can smoothly pass through the through-hole of the second band part 300, and after the penetration, the vertical surface of the fixing protrusion 210 is the through-hole. Since it is exposed to the outside by a predetermined length, the first band part 200 does not arbitrarily separate from the second band part 300 and maintains a fastened state unless a force equal to or greater than the reference pressure is applied. In addition, only one fixing hole 310 may be formed, but since the optimum fastening position for fixing the catheter 1000 may change according to the diameter of the catheter 1000, the longitudinal direction of the second band part 300 may be changed. It may be provided with a plurality according to.

The adhesive pad 400 is disposed between the fixing part 100 and the user's skin to play a role of securing the position of the fixing part 100 more stably. To this end, the adhesive pad 400 is made of a flat plate-shaped member having a relatively large area compared to the fixing part 100, and a second adhesive surface 410 to which an adhesive is applied is formed on one surface of the user's skin. To enable the adhesive pad 400 to be attached to. Although the second adhesive surface 4100 is named in the present invention, it may mean an adhesive layer formed by applying an adhesive to one surface of the adhesive pad 400 . In this case, the second adhesive surface 410 may be additionally provided with a release paper to prevent the adhesive pad 400 from being arbitrarily attached. In the present invention, although the adhesive pad 400 is shown as a quadrangular pad, this is only one embodiment and the shape of the adhesive pad 400 may be formed in various shapes. As described above, since the adhesive pad 400 has a relatively large area compared to the fixing part 100, it maintains a relatively stable attachment state compared to when the fixing part 100 is directly attached to the user's skin. Any material may be used as long as the material of the adhesive pad 400 can maintain the adhesive state when the first adhesive surface 120 of the fixing part 100 is bonded, but preferably the user's skin. It is recommended to use a material with a smooth surface that does not cause skin disease even if it is in contact for a long time.

In the lock-type catheter failure device 10 having the above-described configuration, in one embodiment, one first band part 200 and one second band part 300 are provided on both sides of one fixing part 100, respectively. Although described, two or more first band parts 200 and two or more second band parts 300 may be provided on both sides of one fixing part 100 to correspond to each other, depending on the usage mode.

In addition, although one fixing part 100 is mainly described and shown attached to one adhesive pad 400, one adhesive pad 400 may be used depending on the usage mode and the size and shape of the adhesive pad 400. It is obvious that a plurality of fixing parts 100 may be attached to.

In addition, the lock-type catheter fixing device 10 having the above configuration may perform a polishing treatment on at least one surface facing the catheter 1000 in order to improve the fixing force by increasing the frictional force with the catheter 1000.

Usage mode of lock-type catheter fixation device

When the usage mode of the lock-type catheter fixing device 10 having the above configuration is described in more detail with reference to the drawings as follows.

First, the adhesive pad 400 is attached to the user's skin corresponding to the position where the catheter 1000 is to be fixed. To this end, the release paper attached to the second adhesive surface 410 of the adhesive pad 400 is removed, and the adhesive pad 400 is attached so that the second adhesive surface 410 faces the user's skin. At this time, since the attachment pad has a relatively large area compared to the fixing part 100, it can be stably attached to the user's skin by minimizing the influence of human body curves and wrinkles.

8 is a perspective view showing a state in which a catheter is inserted into the lock-type catheter fixing device according to the first embodiment of the present invention, and FIG. 9 is a lock-type catheter fixing device according to the first embodiment of the present invention pressurizing and fixing the catheter. 10 is a perspective view showing a state in which a catheter is inserted into a lock-type catheter fixing device according to a second embodiment of the present invention. Next, the fixing part 100 is attached to one side of the upper surface of the adhesive pad 400 . To this end, the release paper attached to the first adhesive surface 120 of the fixing unit 100 is removed, and the first adhesive surface 120 faces the upper surface of the adhesive pad 400 and is attached. At this time, as shown in FIG. 8 or 10, the attachment of the fixing part 100 is attached so that the placement position of the catheter 1000 and the incision 130 of the fixing part 100 correspond to each other. Since the upper surface of the adhesive pad 400 is made of a material having a smooth surface without wrinkles like the user's skin, more stable attachment is possible compared to direct attachment to the user's skin.

Of course, depending on the usage mode, the fixing part 100 may be attached to the user's skin without attaching the adhesive pad 400 . The adhesive applied to the first adhesive surface 120 according to the present invention can be stably attached to the skin through sufficient experiments, but for more stable attachment in consideration of the patient's condition and the strength of movement, the adhesive pad 400 It is just to utilize, the adhesive pad 400 is not essential. In addition, depending on the usage mode, one surface of the fixing part 100 may be integrally formed with the adhesive pad 400, and the arrangement of the fixing part 100 may be completed only by attaching the adhesive pad 400.

Next, as shown in FIG. 8 or 10 , the catheter 1000 is inserted through the incision 130 of the fixing part 100 . In this way, only the process of inserting the catheter 1000 into the fixing part 100 does not cause a large movement of the catheter 1000 or the patient, and the catheter 1000 remains inserted into the fixing part 100. maintain. Furthermore, since the first pressing protrusion 110 inside the fixing part 100 presses the outer circumferential surface of the catheter 1000, the catheter 1000 can be fixed more stably.

11 is a perspective view showing a state in which the lock-type catheter fixing device pressurizes and fixes the catheter according to the second embodiment of the present invention. Next, when the first band part 200 and the second band part 300 are fastened so as to surround the fixing part 100, the first band part 200 and the second band part 300 are fixed from the outside of the fixing part 100. Since the pressure is applied, the catheter 1000 can be stably fixed without opening the incision 130 of the fixing part 100 . The fastening process of the first band unit 200 and the second band unit 300 will be described in more detail as follows.

First, the outer circumferential surface of the fixing part 100 is wrapped by pulling the first band part 200 with a predetermined force.

At this time, in the case of the lock-type catheter fixing device 10 according to the first embodiment, the first pressing protrusion 110 protruding in an arc shape contacts the outer circumferential surface of the catheter 1000 and corresponds to the outer circumferential surface of the catheter 1000. It is bent as much as possible and pressurizes the catheter 1000. At this time, since a semicircular groove is formed in the fixing part 100 corresponding to one side on which the first pressing protrusion 110 is formed, the groove part is bent together, and even if the catheter 1000 is pressed, the catheter 1000 is not deformed. It is possible to stably pressurize the catheter 1000 without causing any pressure. In addition, since the first pressing protrusion 110 is formed on both side walls at a position relatively higher than the inner center of the fixing part 100, since the catheter 1000 is pressurized downward, a pair of first pressing protrusions ( 110) and the fixing part 100, the catheter 1000 can be stably fixed because the catheter 1000 is pressurized at three parts of the inner bottom surface. And, although not shown in detail in the drawing, since the fixing part 100 is made of an elastic material, both ends of the fixing part 100 at which the incision 130 is formed are also formed in the first band part 200 and the second band part 300, which will be described later. ) is bent inward by the wrapping pressure and may press the upper surface of the catheter 1000.

12 is a side view showing a state in which the lock-type catheter fixing device according to the second embodiment of the present invention pressurizes and fixes the catheter, and FIG. 13 is a lock-type catheter fixation device according to the second embodiment of the present invention presses the catheter. It is a side view showing another state of being fixed by

If, in the case of using the lock-type catheter fixing device 10 according to the second embodiment, a plurality of thin rod-shaped first pressing protrusions 110 protruding toward the inside of the fixing part 100 are provided for the catheter 1000. While bending along the outer circumferential surface, the catheter 1000 is pressurized and fixed. At this time, as the first pressing protrusions 110 are radially formed to be spaced apart at equal intervals on the inner side of the fixing part 100, the catheter 1000 can be stably fixed to the center of the fixing part 100.

In addition, as in the second embodiment, when the second pressing protrusion 220 protrudes from the first band part 200, the cross-sectional area of the hollow part of the fixing part 100, the protruding length of the first pressing protrusion 110, As shown in FIG. 12, the second pressure protrusion 220 provided on the first band part 200 according to the diameter of the catheter 1000 is disposed at a position corresponding to the incision 130 of the fixing part 100. When it is inserted into the incision 130 and supports the catheter 1000 from the top, suppression of the up and down movement of the catheter 1000 can be minimized. In another usage mode, if the second pressing protrusion 220 provided on the first band part 200 is not disposed at a position corresponding to the cutout 130 of the fixing part 100, as shown in FIG. 13, The second pressure protrusion 220 is bent to close the incision 130 of the fixing part 100, and the bent second pressure protrusion 220 presses the end of the incision 130 downward, thereby opening the catheter 1000. Up and down movement of the clothes can be suppressed.

As described above, in a state in which the first band unit 200 is pulled to surround the fixing unit 100, the second band unit 300 is pulled in the direction of the first band unit 200 with a predetermined force, and the second band unit 300 The first band part 200 and the second band part 300 are fastened by selecting an optimal position among the plurality of fixing holes 310 provided along the length direction of the . At this time, since the end of the first band part 200 is gradually thinner toward the end, even if the end of the first band part 200 and the center of the fixing hole 310 of the second band part 300 do not coincide, the first The band part 200 can be easily inserted into the fixing hole 310, and is naturally centered along the longitudinal slope and fastened. In addition, since the fixing hole 310 is formed in a 'T' shape, the first band part 200 can pass through the fixing hole 310 without being caught by the second pressing protrusion 220 of the first band part 200. can In addition, although the maximum width of the fixing protrusion 210 of the first band part 200 is formed wider than the width of the fixing hole 310, the first band part 200 and the second band part 300 are made of an elastic material and fastened. An inclined surface is formed along the direction so that the fixing protrusion 210 can be inserted into the fixing hole 310 of the second band part 300 without much difficulty. However, since the maximum width of the fixing protrusion 210 of the first band part 200 is wider than the width of the fixing hole 310, the vertical surface of the fixing protrusion 210 is caught by the fixing hole 310 and is not arbitrarily separated. That is, if the user does not pull the first band part 200 with a force equal to or greater than a certain pressure for separation, the first band part 200 is not separated by a simple movement of the patient or the catheter 1000, so stable fastening is possible.

In the above process, for convenience of explanation, the fixing part 100 is wrapped around the first band part 200 and then wrapped around the fixing part 100 through the second band part 300. It is only for convenience and does not limit the fastening order of the first band part 200 and the second band part 300 . That is, it is obvious that the second band unit 300 may be wrapped first, or the first band unit 200 and the second band unit 300 may be tightened by pulling at the same time, depending on the usage mode.

In addition, the fastening of the first band part 200 and the second band part 300 will be described based on an embodiment in which the first band part 200 is coupled through the fixing hole 310 of the second band part 300. However, it is obvious that it can be coupled through various fastening methods.

As described above, those skilled in the art to which the present invention pertains will understand that the present invention can be embodied in other specific forms without changing the technical spirit or essential characteristics thereof. Therefore, the above-described embodiments should be understood as illustrative in all respects and not limiting. The scope of the present invention is indicated by the following claims rather than the detailed description, and all changes or modifications derived from the meaning and scope of the claims and equivalent concepts should be construed as being included in the scope of the present invention.
