Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of nursing devices, and particularly relates to a catheter interface protection device. Background Art
[0002] Peritoneal dialysis is a treatment technology that uses the human peritoneum as a semipermeable membrane, takes the abdominal cavity as an exchange space, and removes excessive water, metabolites and toxins in the body through diffusion and convection to achieve blood purification and replace the kidney function. It is one of the effective kidney replacement treatment methods for treating acute kidney injury and chronic renal failure. During peritoneal dialysis treatment, a doctor needs to insert one end of the peritoneal dialysis catheter into the abdominal cavity, and the other end remains outside the abdominal cavity as a passage for dialysis fluid to enter and exit the abdominal cavity. The connecting short tube with a knob switch is connected thereto. During the treatment period, the peritoneal dialysis outlet catheter and the dialysis equipment connecting catheter need to be continuously connected. During the process of connecting the outlet catheter to the connecting catheter and removing the connecting catheter at the end of the treatment, it is easy to cause contamination at the interface. Moreover, during the long treatment period, due to the patient's random movement or turning over, it is also very easy for the interface between the outlet catheter and the connecting catheter to contact the outside world or even disconnect, increasing the risk of infection.

[0022] In order to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the solution of the present utility model will be further described below. It should be noted that, without conflict, the embodiments of the present utility model and the features in the embodiments can be combined with each other.
[0023] In the following description, many specific details are set forth in order to fully understand the present utility model, but the present utility model can also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only a part of the embodiments of the present utility model, rather than all the embodiments.
[0024] The catheter interface protection device will be described in detail through specific embodiments as follows:
[0025] As Figures 1 to 3 shown, a catheter interface protection device provided by the present utility model is used to protect the interface between the peritoneal exit catheter 5 and the dialysis equipment connection catheter 6 during peritoneal dialysis, and includes: a first adhesive surface 1, a protective surface 2 and a second adhesive surface 3; a first adhesive surface 1 is formed on the first side of the protective surface 2, the first adhesive surface 1 and the protective surface 2 are on the same horizontal plane, and the first adhesive surface 1 extends in the direction away from the first side of the protective surface 2; a second adhesive surface 3 is provided at one end of the protective surface 2 away from the first adhesive surface 1, the second adhesive surface 3 and the protective surface 2 are on the same horizontal plane, and the second adhesive surface 3 extends along the direction of the side line adjacent to the first side of the protective surface 2.
[0026] The first side of the above-mentioned protective surface 2 refers to one of the edges along the protective surface 2. One edge of the first adhesive surface 1 can coincide with the first side of the protective surface 2. It can be understood that the area of the first adhesive surface 1 is smaller than that of the protective surface 2, and the first adhesive surface 1 can also be integrally cut and formed with the protective surface 2. A medical adhesive layer can be provided on the first adhesive surface 1 as long as it can have adhesiveness. The first adhesive surface 1 extends in a direction away from the first side of the protective surface 2, that is to say, the first adhesive surface 1 protrudes from the protective surface 2 and is coplanar with the protective surface 2. The above-mentioned second adhesive surface 3 can be provided at one end of the protective surface 2 away from the first adhesive surface 1, or the second adhesive surface 3 can be formed along the other edge of the protective surface 2. The above-mentioned edge adjacent to the first side of the protective surface 2 refers to the second side adjacent to the first side on the protective surface 2, and the second adhesive surface 3 extends along the direction of the second side. If the protective surface 2 is rectangular and the first side is the length of the rectangle, then the second adhesive surface 3 extends along the width direction of the rectangle and fits with the wide side of the rectangle. At the same time, the first adhesive surface 1 is provided at one end of the rectangle's length, and the second adhesive surface 3 is provided at the other end of the rectangle's length and fits with the width of the rectangle. That is to say, the first adhesive surface 1 and the second adhesive surface 3 are respectively provided at both ends in the length direction of the rectangle, and the first adhesive surface 1 protrudes from the rectangle.
[0027] Therefore, when the operator needs to perform peritoneal dialysis, one end of the first adhesive surface 1 is brought close to the peritoneal exit catheter 5 of the patient, and one end of the second adhesive surface 3 is brought close to one end of the dialysis device connection catheter 6. The protective surface 2 is laid at the interface so that the interface between the peritoneal exit catheter 5 and the dialysis device connection catheter 6 is located at the center of the protective surface 2. Then, the edge of the first adhesive surface 1 is pulled by hand to fold the protective surface 2, thereby wrapping the interface between the peritoneal exit catheter 5 and the dialysis device connection catheter 6. At this time, the second adhesive surface 3 can bond and fix the dialysis device connection catheter 6 to prevent the device from moving and causing the catheter to fall off. Further, the first adhesive surface 1 is bonded to the back of the folded protective surface 2 to prevent the peritoneal exit catheter 5 from being adhered, resulting in infection and injury at the patient's abdominal wound, and further avoiding the occurrence of catheter-related infections and peritonitis. During the entire operation process, the interface between the peritoneal exit catheter 5 and the dialysis device connection catheter 6 will not be touched by the operator, and the wrapped interface can avoid being polluted by the external environment. At the same time, the patient can avoid catheter-related infections caused by the patient's random twisting and pressing the interface during dialysis. At the end of the treatment, the first adhesive surface 1 exposed on the outer layer can be directly torn off to disconnect the peritoneal exit catheter 5 from the dialysis device connection catheter 6, and the device together with the dialysis device connection catheter 6 can be thrown into the designated trash can. It can be understood that after the peritoneal exit catheter 5 and the dialysis device connection catheter 6 are disconnected, they can be protected with sterile devices such as caps. Further, the material of the protective surface 2 can be set as a disposable item. For example, it can be non-woven fabric.
[0028] The catheter interface protection device provided by the utility model has a first adhesive surface 1 formed on the first side of the protection surface 2. One end of the protection surface 2 away from the first adhesive surface 1 is provided with a second adhesive surface 3. The second adhesive surface 3 is on the same horizontal plane as the protection surface 2, and the second adhesive surface 3 extends along the direction of the side adjacent to the first side of the protection surface 2. Therefore, the interface between the peritoneal outlet catheter 5 and the dialysis equipment connection catheter 6 can be placed on the protection surface 2. By lifting the first adhesive surface 1, the protection surface 2 is wound around the catheter to wrap the interface, avoiding contamination caused by the operator touching the interface during operation and also avoiding the catheter interface being polluted by the external environment when the patient moves.
[0029] Further, the protection surface 2 is rectangular.
[0030] The above protection surface 2 is set to be rectangular. Therefore, the first adhesive surface 1 can be set at one end of the rectangle's length, and the second adhesive surface 3 is set at the other end of the rectangle's length and fits with the width of the rectangle. The protection surface 2 is folded along the length direction of the rectangle, and the interface between the peritoneal outlet catheter 5 and the dialysis equipment connection catheter 6 is placed at the center of the rectangle. Of course, the protection surface 2 can also be other shapes, which are specifically set according to the actual usage situation.
[0031] In some embodiments, a tear strip 4 is provided on the protection surface 2, and the tear strip 4 is parallel to the first side of the protection surface 2.
[0032] The above setting of the tear strip 4 facilitates the operator to directly tear the protection surface 2 through the tear strip 4 at the end of the treatment, and then disconnect the peritoneal outlet catheter 5 from the dialysis equipment connection catheter 6, which is convenient for operation.
[0033] In some other embodiments, both the first adhesive surface 1 and the second adhesive surface 3 are self-adhesive breathable adhesive tapes. This is convenient for maintaining breathable cleanliness during treatment and reducing the risk of infection.
[0034] Further, a sterile layer is provided on the protection surface 2, and the area of the sterile layer is equal to the area of the protection surface 2. The sterile layer is sterile non-woven fabric.
[0035] Setting the protection surface 2 as sterile non-woven fabric, on the one hand, it reduces resource waste and is convenient for single use. On the other hand, when the sterile non-woven fabric wraps the interface between the peritoneal outlet catheter 5 and the dialysis equipment connection catheter 6, it further ensures a sterile environment and thus prevents infection.
[0036] As Figure 2 shown, the second adhesive surface 3 includes a second upper adhesive surface 31 and a second lower adhesive surface 32, and there is a non-adhesive area between the second upper adhesive surface 31 and the second lower adhesive surface 32.
[0037] The above arrangement divides the second adhesive surface 3 into a second upper adhesive surface 31 and a second lower adhesive surface 32, and the middle is a non-stick area, so as to prevent the dialysis equipment connecting catheter 6 from directly bonding to the second adhesive surface 3 when the protective surface 2 is placed at the bottom of the interface at the beginning, resulting in the inability to adjust the catheter position. To set the non-stick area, the dialysis equipment connecting catheter 6 can be placed in the non-stick area first, and after adjusting the position, the protective surface 2 is rolled up so that the second upper adhesive surface 31 and the second lower adhesive surface 32 are bonded and fixed to the dialysis equipment connecting catheter 6.
[0038] Furthermore, a waterproof layer is provided on a side of the protective surface 2 facing away from the catheter interface.
[0039] The waterproof layer may be a medical waterproof material to prevent water vapor or water droplets from the external environment from penetrating into the protective layer during treatment, thereby causing infection of the catheter interface.
[0040] In some embodiments, release paper is provided on the first adhesive surface 1 and the second adhesive surface 3 .
[0041] In the initial state, the release paper can protect the first adhesive surface 1 and the second adhesive surface 3 to prevent dust or other impurities from falling in and affecting the bonding effect. When in use, the release paper can be peeled off and then used.
[0042] In some other embodiments, a fold is provided on the protective surface 2 , and the fold is parallel to the first side of the protective surface 2 .
[0043] When in use, the catheter can be directly placed in the fold, which is convenient for positioning the catheter on the one hand, and can temporarily fix the catheter for easy rolling and wrapping on the other hand. It can be understood that the material of the protective surface 2 can be processed into a fold, and the length of the fold is the same as the length of the first side of the protective surface 2.
