Description

Technical Field

[0001] The invention belongs to the technical field of peritoneal dialysis, and particularly relates to a skin fitting device for peritoneal dialysis in nephrology. Background Art

[0002] When performing peritoneal dialysis, an external pipeline needs to be penetrated and fixed on the patient's abdomen. In order to prevent the patient from pulling the external pipeline during daily life, resulting in wound dehiscence or displacement of the external pipeline, currently, a nursing sticker is mostly used to paste the external pipeline on the patient's abdomen for fixation. When in use, the external pipeline can be directly connected to the infusion tube after being removed from the nursing sticker. The whole operation is convenient, so it is widely used.

[0003] However, since most elderly patients usually recuperate in bed and have loose and wrinkled skin, there are great limitations in the pasting position and tearing and replacement of the nursing sticker. Compared with young patients, the waist of elderly patients is more likely to develop pressure sores after wearing a belt for a long time. When performing peritoneal dialysis after removing the external catheter, the external catheter needs to be connected to the infusion tube, and inevitably, the rotation switch will be pulled. At this time, since the external catheter is not fixed to the skin, it is extremely easy to cause stretching displacement of the external pipeline. Elderly patients usually have a thinner abdominal wall and a smaller abdominal cavity space. The displacement of the external pipeline is extremely likely to interfere with the normal movement of the abdomen, leading to problems such as a decrease in the sealing effect, liquid leakage, or wound inflammation and infection. In addition, when performing peritoneal dialysis, medical staff need to constantly pay attention to whether there is leakage at the wound, which causes the patient's abdomen to be exposed to the outside for a long time. Elderly patients have a poor constitution and are easily affected by temperature changes in the abdomen, which is extremely likely to increase abdominal discomfort. Summary of the Invention

[0004] The purpose of the invention is to provide a skin fitting device for peritoneal dialysis in nephrology to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the invention provides the following technical solution: A skin fitting device for peritoneal dialysis in nephrology includes a bellyband. Second magic tapes are symmetrically installed on the lower parts of the outer surfaces of the bellyband near its two sides. Through holes are equidistantly arranged on the bellyband between the second magic tapes. An external catheter is penetrated through the inside of the through holes. A titanium joint and a rotary switch are fixedly installed on the external catheter. A rotating layer is also sewn on the outer surface of the bellyband. The rotating layer is located above the second magic tapes. First magic tapes are symmetrically installed on the inner surfaces of the rotating layer near its two sides. The first magic tapes are adhered to the second magic tapes. An elastic cloth is sewn on the inner surface of the rotating layer. The elastic cloth is located between the first magic tapes. The titanium joint and the rotary switch are clamped and fixed inside the elastic cloth.

[0006] Preferably, third magic tapes are symmetrically installed on the surfaces of the bellyband near its two sides. The third magic tapes are located above the rotating layer. One side of the bellyband is fixedly connected with elastic flannelette in the middle. A fifth magic tape is fixedly installed on the side of the elastic flannelette away from the bellyband. The fifth magic tape can be adhered to the third magic tape.

[0007] Preferably, stretching holes are equidistantly formed on the surface of the elastic flannelette. The stretching holes are located between the fifth magic tape and the bellyband. Fourth magic tapes are symmetrically arranged on the outer surfaces near the two sides of the rotating layer. The fourth magic tapes can be adhered to the third magic tapes.

[0008] Preferably, a connecting cloth is sewn on the inner surface of the rotating layer close to the bellyband. Limiting holes are equidistantly formed in the connecting cloth. The external catheter is arranged inside the external catheter.

[0009] Preferably, a perforation is formed in the center of the rotating layer. The perforation is located between the elastic cloths. Rubber strips are equidistantly sewn inside the perforation. The external catheter between the titanium joint and the rotary switch alternately passes through the inside of the perforation and contacts the surface of the rubber strip. The distance between the rubber strips is smaller than the diameter of the titanium joint.

[0010] Preferably, filling grooves are symmetrically arranged inside the rotating layer near its two sides. The filling grooves are located between the fourth magic tape and the first magic tape. Filling strips are filled inside the filling grooves. The thickness of the filling strips is the same as the diameters of the titanium joint and the rotary switch.

[0011] Preferably, a cashmere fabric is sewn on the bellyband. The cashmere fabric is located between the second magic tapes. Through holes are equidistantly formed in the cashmere fabric. The inner surface of the cashmere fabric contacts the skin of the patient.

[0012] Preferably, color-changing water-sensitive stickers are fixedly pasted on the outer surface of the cashmere fabric at equal intervals. The color-changing water-sensitive stickers are located between the through holes. The detection surface of the color-changing water-sensitive stickers contacts the cashmere fabric.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] (1) The present invention is provided with elastic cloth, rubber strips, perforations, etc. When in use, medical staff only need to remove the rotary switch from the elastic cloth. Since the external catheter is alternately threaded between multiple rubber strips, even if the rotary switch is stretched, the titanium joint will be blocked because of its relatively large diameter and inability to quickly pass through the small holes between the rubber strips. Coupled with the frictional force formed by the alternating threading of multiple rubber strips and the external catheter, the stretching effect of the rotary switch is further restricted, thereby achieving the purpose of fixing the external catheter.

[0015] (2) The present invention is provided with cashmere fabric, color-changing water-sensitive stickers, external catheter, etc. When performing peritoneal dialysis, it is necessary to first peel off the adhesion of the first magic tape and the second magic tape and then reverse the rotating layer to expose the cashmere fabric. Since the external catheter is threaded through the cashmere fabric, when there is a leakage at the wound, the cashmere fabric will quickly absorb the leaked liquid, causing the color-changing water-sensitive sticker pasted above the cashmere fabric to come into contact with the absorbed liquid, and thus causing a color change.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1-3As shown in the figure, the present invention provides the following technical solution: A skin fitting device for peritoneal dialysis in nephrology department includes a bellyband 17. Symmetrically installed on the lower part of the outer surface of the bellyband 17 near its two sides are second magic tapes 12. Through holes 14 are evenly arranged on the bellyband 17 between the second magic tapes 12. An external catheter 11 is passed through the inside of the through hole 14. A titanium joint 7 and a rotary switch 4 are fixedly installed on the external catheter 11. A rotating layer 3 is also sewn on the outer surface of the bellyband 17. The rotating layer 3 is located above the second magic tape 12. Symmetrically installed on the inner surface of the rotating layer 3 near its two sides are first magic tapes 8. The first magic tapes 8 are adhered to the second magic tapes 12. An elastic cloth 9 is sewn on the inner surface of the rotating layer 3. The elastic cloth 9 is located between the first magic tapes 8. The titanium joint 7 and the rotary switch 4 are clamped and fixed inside the elastic cloth 9. Symmetrically installed on the surface of the bellyband 17 near its two sides are third magic tapes 18. The third magic tapes 18 are located above the rotating layer 3. Fixedly connected to the middle of one side of the bellyband 17 is an elastic fleece 2. Fixedly installed on the side of the elastic fleece 2 away from the bellyband 17 is a fifth magic tape 20. The fifth magic tape 20 can be adhered to the third magic tape 18. Uniformly arranged on the surface of the elastic fleece 2 are stretching holes 1. The stretching holes 1 are located between the fifth magic tape 20 and the bellyband 17. Symmetrically arranged on the outer surface of the rotating layer 3 near its two sides are fourth magic tapes 19. The fourth magic tapes 19 can be adhered to the third magic tape 18. A perforation 6 is opened in the center of the rotating layer 3. The perforation 6 is located between the elastic cloth 9. And evenly sewn inside the perforation 6 are rubber strips 5. The external catheter 11 between the titanium joint 7 and the rotary switch 4 alternately passes through the inside of the perforation 6 and contacts the surface of the rubber strip 5. The distance between the rubber strips 5 is smaller than the diameter of the titanium joint 7.

[0023] Through the above technical solution, during installation, gently pull one end of the rotary switch 4, and after it passes through the through hole 14 and is arranged on the bellyband 17, cover the bellyband 17 on the patient's abdomen. Then pull the elastic fleece 2 on one side to wrap around the patient's waist and fix it through the adhesion of the third magic tape 18 and the fourth magic tape 19. By using the relatively thin thickness of the elastic fleece 2, the problem that pressure sores are likely to appear on the waist after the patient wears a traditional waistband for a long time is reduced. At the same time, with the cooperation of the opened stretching holes 1, the elasticity of the elastic fleece 2 is further increased, and the pressure of the elastic fleece 2 and the bellyband 17 on the patient's abdomen is reduced, ensuring the smooth flow of blood and respiration in the abdomen of elderly patients, improving the wearing comfort, and reducing the problems of dyspnea or poor blood flow.

[0024] Subsequently, the rotary switch 4 and the titanium joint 7 are inserted inside the elastic cloth 9, and the external catheter 11 between the titanium joint 7 and the rotary switch 4 is inserted through the perforation 6, allowing this section of the external catheter 11 to alternately pass through the upper and lower sides of a plurality of rubber strips 5. Subsequently, the rotating layer 3 is adhesively fixed to the bellyband 17 through the first magic tape 8 and the second magic tape 12. When in use, by tearing the rotating layer 3 to separate the first magic tape 8 and the second magic tape 12 from adhesion, after the titanium joint 7 and the rotary switch 4 are exposed, the rotary switch 4 can be removed from the elastic cloth 9 to connect the infusion tube. Even if the rotary switch 4 is stretched during this period, due to the relatively large diameter of the titanium joint 7 itself, it cannot quickly pass through the small holes between the rubber strips 5 and thus generates a blockage. Coupled with the frictional force formed by the alternating arrangement of the plurality of rubber strips 5 and the external catheter 11, the stretching effect of the rotary switch 4 is further restricted, thereby achieving the purpose of fixing the external catheter 11.

[0025] Furthermore, a connecting cloth 10 is sewn on the inner surface of the rotating layer 3 close to the bellyband 17. A plurality of limiting holes 15 are equidistantly arranged on the connecting cloth 10, and the external catheter 11 is inserted inside the external catheter 11.

[0026] Please refer to Figure 1 , after the rotary switch 4 is inserted through the through hole 14 on the bellyband 17, the rotary switch 4 still needs to be pulled continuously so that it passes through the limiting hole 15 and is inserted into the connecting cloth 10 and then into the elastic cloth 9. By using the connecting cloth 10 and the limiting holes 15, the movement of the external catheter 11 is restricted. When the rotating layer 3 is closed, the external catheter 11 is pulled by the connecting cloth 10 so that the external catheter 11 between the titanium joint 7 and the patient's abdomen is in a folded state, preventing the external catheter 11 from penetrating deep into the patient's abdomen under the action of its own elasticity after the rotating layer 3 is closed, thereby avoiding the problem of irritating the patient's abdomen.

[0027] Furthermore, filling grooves 22 are symmetrically arranged inside the rotating layer 3 near its two sides. The filling grooves 22 are located between the fourth magic tape 19 and the first magic tape 8, and the inside of the filling grooves 22 is filled with filling strips 21. The thickness of the filling strips 21 is the same as the diameters of the titanium joint 7 and the rotary switch 4.

[0028] Please refer to Figure 4 , by using the filling strips 21 to increase the thickness of the two sides of the rotating layer 3 so that it is flush with the rotary switch 4 and the titanium joint 7. After the rotating layer 3 is adhesively fixed to the bellyband 17 through the first magic tape 8 and the second magic tape 12, the rotary switch 4 and the titanium joint 7 will not squeeze the patient's abdomen, eliminating the problem that the rotary switch 4 and the titanium joint 7 squeeze the patient's abdomen due to adhesive fixation, resulting in discomfort in the patient's abdomen, thereby improving the overall comfort of wearing.

[0029] Furthermore, cashmere fabric 16 is sewn on the bellyband 17, and the cashmere fabric 16 is located between the second Velcro 12. Through holes 14 are evenly spaced on the cashmere fabric 16, and the inner surface of the cashmere fabric 16 is in contact with the patient's skin. Color-changing water-sensing stickers 13 are evenly spaced and fixed on the outer surface of the cashmere fabric 16. The color-changing water-sensing stickers 13 are located between the through holes 14, and the detection surface of the color-changing water-sensing stickers 13 is in contact with the cashmere fabric 16.

[0030] Please refer to Figure 1 and Figure 3 When performing peritoneal dialysis, medical staff need to first peel off the adhesion of the first Velcro 8 and the second Velcro 12 and then reverse the rotating layer 3, so that the external catheter 11, the titanium joint 7 and the rotary switch 4 clamped and fixed between the rotating layer 3 and the bellyband 17 are exposed, and the cashmere fabric 16 is also exposed synchronously while facilitating the connection of the infusion tube. Since the cashmere fabric 16 itself has high elasticity, at this time, the other through holes 14 without the external catheter 11 are mostly in a closed state under the action of the elasticity of the cashmere fabric 16 itself, preventing the external cold air from directly contacting the patient's abdomen, and then cooperating with the cashmere fabric 16 and the bellyband 17 to improve the covering and heat preservation effect of the patient's abdomen. At the same time, since the external catheter 11 is inserted on the cashmere fabric 16, and the cashmere fabric 16 is directly The cashmere fabric 16 directly covers the wound, so when the wound leaks, the cashmere fabric 16 will quickly absorb the leaked liquid, so that the color-changing water-sensing sticker 13 pasted and covering the cashmere fabric 16 comes into contact with the absorbed liquid, and the color-changing water-sensing sticker 13 will change color immediately after absorbing the liquid. Medical staff do not need to lift the bellyband 17 during peritoneal dialysis, so that the bellyband 17 can cover the patient's abdomen throughout the process, preventing the abdomen from being easily affected by temperature changes and causing adverse effects, thereby further improving the overall comfort of wearing. At the same time, medical staff only need to observe the color change of the color-changing water-sensing sticker 13 to determine whether there is a leakage problem, and the cashmere fabric 16 increases the thermal insulation effect near the wound, further increasing the wearing comfort of elderly patients.
