Description

Technical Field

[0001] The present application relates to the technical field of peritoneal dialysis tube fixing equipment, and in particular to a peritoneal dialysis catheter fixing wing. Background Art

[0002] Peritoneal dialysis is an effective renal replacement therapy for end-stage renal disease, and the peritoneal dialysis catheter is the "lifeline" of peritoneal dialysis patients. During long-term dialysis, if the peritoneal dialysis catheter exposed to the abdominal wall is not fixed, the peritoneal dialysis catheter will rub back and forth with the patient's skin at the tunnel outlet, causing granulation hyperplasia at the patient's skin at the tunnel outlet, and then inducing related complications such as tunnel outlet infection. This not only increases the patient's pain, but may also cause abdominal cavity infection due to exit infection, and terminate peritoneal dialysis treatment. Therefore, it is usually necessary to fix the peritoneal dialysis catheter exposed to the abdominal wall to avoid affecting peritoneal dialysis treatment.

[0003] Currently, peritoneal dialysis catheters are often fixed in clinical practice by wrapping a peritoneal dialysis catheter belt around the patient's waist and abdomen, and then placing the peritoneal dialysis catheter into several buckles on the catheter belt, thereby achieving simple positioning of the peritoneal dialysis catheter.

[0004] However, in actual use, it is found that the above method has the following disadvantages when fixing the peritoneal dialysis catheter:

[0005] 1. The catheter belt is loosely tied during use. When the catheter belt moves, the peritoneal dialysis catheter will move with it. When the position of the catheter belt is far away from the patient's tunnel outlet, it is easy to pull the peritoneal dialysis catheter;

[0006] 2. During peritoneal dialysis fluid exchange, the catheter and peritoneal dialysis fluid are connected for injection and drainage of peritoneal dialysis fluid. When the amount of peritoneal dialysis fluid flowing into the drainage bag increases, the peritoneal dialysis catheter is easily pulled due to the influence of gravity and the distance between the patient and the drainage tube.

[0007] In summary, limiting the peritoneal dialysis catheter by a catheter belt is prone to traction and is inconvenient to use. Utility Model Content

[0008] In order to achieve the purpose of fixing the peritoneal dialysis catheter during peritoneal dialysis and avoiding the patient's wound infection caused by traction of the peritoneal dialysis catheter, the present application provides a peritoneal dialysis catheter fixing wing.

[0009] The present application provides a peritoneal dialysis catheter fixing wing, which adopts the following technical solution:

[0010] A peritoneal dialysis catheter fixing wing, comprising a fixing seat, a bottom surface of the fixing seat being provided with an adhesive sticker for sticking on the patient's skin, the fixing seat being provided with an embedding groove for embedding the catheter, the fixing seat being provided with a pressing block for pressing a portion of the catheter into the embedding groove, the fixing seat being provided with a fixing structure for preventing the catheter from sliding along its own axial direction, and the fixing seat being provided with a clamping structure for fixing the pressing block.

[0011] By adopting the above technical solution, the fixing seat is placed on the patient's skin 5 to 8 centimeters away from the catheter outlet during use, and the fixing seat is bonded and fixed by adhesive tape. Then, the catheter part is pressed into the embedding groove by the pressing block, so that the catheter part is deformed, thereby preventing the catheter from sliding along its own axis under the action of traction. The clamping structure prevents the pressing block from detaching from the fixing seat, thereby increasing the pressure of the pressing block on the catheter. The fixing structure prevents the two ends of the catheter from swinging. The overall use is simple and convenient, and at the same time ensures the fixation stability of the catheter.

[0012] Preferably, the pressing block comprises a first block body arranged on the fixing seat, a second block body fixedly connected to the first block body, and the second block body is embedded in the embedding groove.

[0013] By adopting the above technical solution, the second block is embedded in the embedding groove during use to achieve squeezing of the catheter, thereby ensuring that the catheter is partially deformed and embedded in the embedding groove.

[0014] Preferably, the first block is provided with an escape groove for escaping the conduit.

[0015] By adopting the above technical solution, an avoidance groove is provided during use so that the catheter can be embedded in the avoidance groove, thereby preventing the catheter from being squeezed when the first block is attached to the fixed seat, thereby affecting the flow rate of the liquid in the catheter. At the same time, the catheter located on the fixed seat is initially limited by the inner wall of the avoidance groove.

[0016] Preferably, the edge of the notch of the avoidance groove is formed with a chamfer.

[0017] By adopting the above technical solution, chamfering is performed during use, so that when the pressing block is pressed down, the catheter is easier to be embedded in the avoidance groove, thereby increasing the convenience of use.

[0018] Preferably, the fixing structure comprises a buckle mounted on the fixing seat, and the buckle is arranged at the end of the fixing seat.

[0019] By adopting the above technical solution, the end of the catheter is fixed and limited by the buckle during use, which is simple and convenient to use and reduces the shaking of the end of the catheter.

[0020] Preferably, the clamping structure includes a strap arranged on the fixed seat, one end of the strap is a fixed end, and the other end is a movable end, the fixed end of the strap is fixedly connected to the fixed seat, the movable end of the strap is provided with a Velcro mother sticker, and the fixed seat is provided with a Velcro sub-strip, and the fixed end and the Velcro sub-strip of the strap are respectively located on both sides of the embedding groove.

[0021] By adopting the above technical solution, the pressing block is bound and compressed by the strap during use, and the movable end of the strap is bonded to the fixing seat by the Velcro, which is simple and convenient to use.

[0022] Preferably, a clamping block is fixedly connected to the fixing seat, and a clamping groove for embedding the clamping block is formed on the first block.

[0023] By adopting the above technical solution, the clamping block is embedded in the clamping groove during use, thereby increasing the stability of the pressing block when squeezing the catheter and avoiding the shaking of the pressing block.

[0024] Preferably, guide bevels are formed on both side edges of the notch of the embedding groove.

[0025] By adopting the above technical solution, the guide slope is provided during use to reduce the deformation of the catheter cup pressing block when it is compressed, thereby avoiding the influence of the liquid flow in the catheter when the deformation angle of the catheter is large.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 1. When in use, the fixing seat is attached to the patient's skin with an adhesive sticker, and then the catheter is placed on the fixing seat. The end of the catheter is fixed by a buckle to prevent the end of the catheter from shaking. The catheter is squeezed by a pressing block so that part of the catheter is deformed and embedded in the groove to prevent the catheter from sliding along its own axis, thereby fixing the catheter on the fixing seat to prevent infection of the patient's wound caused by the traction of the catheter;

[0028] 2. When in use, a guide slope is formed at the notch of the embedding groove, and an avoidance groove is provided on the first block, so as to avoid the influence of the liquid flow in the catheter when the catheter is deformed too much under the pressure of the pressing block;

[0029] 3. When in use, the clamping block is embedded in the clamping groove to achieve initial clamping and limiting of the first block to prevent the pressing block from shaking. The pressing block is bound and squeezed by the strap to perform secondary limiting on the pressing block, thereby preventing the pressing block from detaching from the fixing seat and increasing the downward pressure of the pressing block to ensure that the pressing block presses the catheter into the embedded groove.

[0037] The following is combined with Figure 1 -Attached Figure 6 This application is described in further detail.

[0038] The embodiment of the present application discloses a peritoneal dialysis catheter fixing wing.

[0039] Reference Figure 1 and Figure 2 A peritoneal dialysis catheter fixing wing comprises a fixing seat 1 placed horizontally, a sticker 2 is arranged on the bottom surface of the fixing seat 1, in this embodiment, the sticker 2 preferably uses an anti-allergic medical adhesive layer, a pressing block 4 is arranged on the fixing seat 1, a embedding groove 3 is opened on the top surface of the fixing seat 1, and a clamping structure 6 for preventing the pressing block 4 from detaching from the fixing seat 1 is arranged on the fixing seat 1; when in use, the fixing seat 1 is placed on the patient's skin, the fixing seat 1 is glued and fixed by the sticker 2, a catheter 7 is placed on the fixing seat 1, and the catheter 7 is partially pressed into the embedding groove 3 by the pressing block 4, so that the catheter 7 is partially deformed, thereby preventing the catheter 7 from sliding along its own axis direction under the pulling action.

[0040] Reference Figure 1In this embodiment, the fixing seat 1 and the pressing block 4 are preferably block-shaped objects made of foam material. When in use, by using the fixing seat 1 and the pressing block 4 made of foam material, on the one hand, the overall weight is made lighter and convenient to fix, thereby reducing the situation where the fixing seat 1 or the pressing block 4 falls due to the influence of gravity; on the other hand, when in use, the foam material itself has a certain deformation force, thereby avoiding damage to the catheter 7 when the pressing block 4 presses down the catheter 7, thereby affecting the normal use of the catheter 7.

[0041] Reference Figure 1 and Figure 3 The pressing block 4 includes a first block 41 and a second block 42. The first block 41 is arranged on the top surface of the fixing seat 1, and the second block 42 is integrally formed on the bottom surface of the first block 41. The size of the second block 42 is smaller than that of the first block 41. An avoidance groove 43 is provided on the first block 41. Chamfers 44 are formed on both sides of the notch of the avoidance groove 43. Two avoidance grooves 43 are provided, and the two avoidance grooves 43 are respectively located on both sides of the second block 42. When in use, the catheter 7 is partially pressed into the embedded groove 3 through the second block 42, and the part of the catheter 7 located outside the embedded groove 3 is limited by the side wall of the avoidance groove 43, so as to prevent the catheter 7 from sliding along its own axial direction.

[0042] Reference Figure 2 and Figure 3 A plurality of clamping blocks 11 are integrally formed on the fixing seat 1, and correspondingly, a plurality of clamping grooves 45 are opened on the first block 41. In the present embodiment, four clamping blocks 11 are preferably arranged, and the four clamping blocks 11 are respectively located around the outside of the embedding groove 3; when in use, the clamping blocks 11 are embedded in the clamping grooves 45 to limit the first block 41, thereby preventing the pressing block 4 from sliding on the top surface of the fixing seat 1 as a whole, thereby increasing the stability of the pressing block 4 installed on the fixing seat 1.

[0043] Reference Figure 2 and Figure 4 The edges of both sides of the groove 3 are formed with guide slopes 31. When in use, the pressure block 4 presses down part of the conduit 7, so that the conduit 7 is partially deformed and embedded in the groove 3. The conduit 7 is guided and supported by the guide slopes 31, which is helpful to avoid excessive deformation angle of the conduit 7, thereby reducing the flow rate of the liquid in the conduit 7.

[0044] Reference Figure 1 and Figure 5The clamping structure 6 includes two groups of straps 61 arranged on the top surface of the fixing seat 1, and the two groups of straps 61 are respectively located at both ends of the pressing block 4, one end of the strap 61 is a fixed end, and the other end is a movable end. The fixed end of the strap 61 is fixedly connected to the fixing seat 1, and the movable end of the strap 61 is provided with a Velcro mother sticker 62, and the fixing seat 1 is fixedly connected with a Velcro sub-strip 63; when in use, the pressing block 4 is pressed down so that the clamping block 11 is embedded in the clamping groove 45 to achieve preliminary positioning, and then the movable end of the strap 61 is passed around the pressing block 4, and fixed by the bonding of the Velcro mother sticker 62 and the Velcro sub-strip 63, so that the strap 61 presses the pressing block 4 to prevent the pressing block 4 from detaching from the fixing seat 1, and at the same time increases the downward pressure of the pressing block 4.

[0045] Reference Figure 1 and Figure 6 In order to avoid shaking of the two ends of the catheter 7, a fixing structure 5 for fixing the two ends of the catheter 7 is also provided on the fixing seat 1. The fixing structure 5 includes two groups of buckles 51 arranged on the fixing seat 1. The two groups of buckles 51 are respectively located at the two ends of the fixing seat 1. When in use, the two ends of the catheter 7 are fixed by the buckles 51, so as to avoid shaking of the end of the catheter 7 along the width direction of the fixing seat 1, thereby increasing the stability of the catheter 7 fixed on the fixing seat 1.

[0046] The implementation principle of the embodiment of the present application is as follows: when in use, the fixing seat 1 is adhered and fixed to the patient's abdominal skin through the anti-allergic medical adhesive tape 2, and the specific position is preferably 5 to 8 cm away from the outlet of the catheter 7. Then, a foam pressing block 4 is placed on the fixing seat 1, and a part of the catheter 7 is squeezed through the bottom end of the second block 42, so that the catheter 7 is partially deformed and embedded in the embedding groove 3. At this time, the clamping block 11 is embedded in the clamping groove 45 to perform preliminary fixing and limiting of the pressing block 4, and then the pressing block 4 is tied tightly by the strap 61 to achieve secondary fixation of the pressing block 4, thereby ensuring that the pressing block 4 is not easy to shake or detach from the fixing seat 1, and then the end of the catheter 7 is fixed by two buckles 51, so as to prevent the end of the catheter 7 from swinging and affecting the fixing stability of the catheter 7. The overall use is simple and convenient, and it avoids the sliding of the catheter 7 due to pulling, thereby preventing the patient's wound from being infected.

[0047] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
