Description

Technical Field

[0001] This utility model relates to the field of medical accessories, specifically a ureteral stent replacement dressing. Background Technology

[0002] Ureteral stents are medical devices widely used in urology and gynecology. Surgeons typically implant a ureteral stent under cystoscopy, placing one end in the kidney and the other in the bladder to drain urine and prevent ureteral obstruction, adhesions, and blockages. Clinically used ureteral stents have a limited lifespan, so healthcare professionals need to replace them periodically.

[0003] Removing old ureteral stents poses safety risks.

[0004] First, because the end of the ureteral stent is curled up and has a certain degree of elasticity, and the opening at the end of the ureteral stent contains urine, and the old ureteral stent will pass through the straight abdominal stoma channel during the removal process, the ureteral stent will return to its curled up shape the moment it is removed from the abdominal wound, causing urine to splash onto the medical staff and bed sheets, causing contamination.

[0005] In addition, urine may be spilled during the disposal of old ureteral stents. Utility Model Content

[0006] In view of the problems existing in the prior art, this utility model provides a ureteral stent replacement dressing to solve at least one of the above technical problems.

[0007] To achieve the above objectives, this utility model provides a ureteral stent replacement dressing, comprising a dressing base, characterized in that the dressing base includes a tube-through portion disposed at the top and bottom and an attachment portion for attaching the attachment portion to the body surface;

[0008] Both the upper and lower ends of the tube section are provided with openings, and the upper opening of the tube section is not larger than the lower opening of the tube section.

[0009] The center of the attachment part has a through hole for connecting with the lower end opening of the tube part, and the through hole of the attachment part is connected to the lower end opening of the tube part.

[0010] The attachment part includes an adhesive tape layer and a release paper layer disposed on the upper and lower sides.

[0011] This invention achieves complete coverage of the curled end of the ureteral stent during removal via the perforation section. The adhesive part adheres to the skin. When the curled end of the ureteral stent is within the perforation section, the perforation of the adhesive part is pinched to wrap around the end of the ureteral stent. The ureteral stent, along with the dressing, is then placed in the medical waste bin. This prevents potential urine dissemination during stent transfer. Specifically, when the ureteral stent is almost completely removed from the wound, to prevent urine dissemination, the ureteral stent is not completely removed from the dressing. The adhesive tape is peeled off the skin, the perforation of the adhesive part is pinched to wrap around the end of the ureteral stent, and the ureteral stent, along with the dressing, is then placed in the medical waste bin. This prevents potential urine dissemination during stent transfer.

[0012] The upper opening of the perforation section is no larger than the lower opening of the perforation section. This allows medical personnel to easily pinch and apply the upper opening when removing the ureteral stent, while also saving materials.

[0013] The adhesive layer of the adhesive tape layer is located on the underside of the adhesive tape layer.

[0014] More preferably, the release paper layer is an annular release paper with a notch, the notch penetrating the annular release paper radially.

[0015] More preferably, the tube section is a tapered structure that is narrow at the top and wide at the bottom.

[0016] More preferably, the inner diameter of the upper opening of the tube section is not less than 5 cm;

[0017] The inner diameter of the lower opening of the tube section is not less than 10cm.

[0018] This allows the entire wound to be seen through the opening at the bottom of the adhesive tape when it is applied to the wound.

[0019] More preferably, the axial length of the perforation section is not less than 10 cm, so that when the perforation section is vertical, it can completely cover the curled section at the end of the ureteral stent.

[0020] More preferably, the tube portion includes an inner and outer absorbent layer and a waterproof membrane layer, with the absorbent layer fixed to the inner wall of the waterproof membrane layer. The absorbent layer absorbs urine when it splashes, while the waterproof membrane layer prevents urine penetration.

[0021] More preferably, the absorbent layer is made of absorbent cotton or absorbent resin.

[0022] More preferably, the waterproof membrane layer is made of polyethylene film.

[0023] Alternatively, the material of the tube-penetrating part is adhesive tape, the adhesive layer of the adhesive tape is located on the inner side of the tube-penetrating part, and the adhesive layer of the adhesive tape is bonded to the absorbent layer.

[0024] This facilitates the absorption of urine from the old ureteral stent on the inside.

[0025] Beneficial effects: This utility model has a simple structure and is easy to use. It can effectively reduce the safety hazards caused by urine splashing and scattering during the removal and disposal of old ureteral stents by medical personnel. Attached Figure Description

[0030] The present invention will be further described below with reference to the accompanying drawings.

[0031] See Figures 1 to 3Specific Embodiment 1: A ureteral stent replacement dressing includes a dressing base 1, which includes an upper and lower perforation portion 102 and an attachment portion 104 for attaching to the body surface. Both the upper and lower ends of the perforation portion 102 have openings, with the upper opening 101 not larger than the lower opening 103. The attachment portion 104 has a central perforation for connecting with the lower opening 103 of the perforation portion 102. The perforation of the attachment portion 104 is connected to the lower opening of the perforation portion 102. The attachment portion 104 includes an upper and lower adhesive tape layer 105 and a release paper layer 106. This invention achieves complete coverage of the curled end section of the ureteral stent 2 during removal via the perforation portion 102. The dressing can be adhered to the skin via the attachment portion 104. After the ureteral stent 2 is removed, to prevent urine dissemination, the ureteral stent 2 is not completely removed from the dressing. The dressing is then peeled off the skin, and the perforation of the attachment portion 104 is pinched tightly to cover the end of the ureteral stent 2. The ureteral stent 2, along with the dressing, is then placed in the medical waste bin. This prevents urine dissemination that may occur during the transfer of the ureteral stent 2. The upper opening 101 of the perforation portion 102 is no larger than the lower opening 103 of the perforation portion 102. This allows medical personnel to easily pinch the upper opening 101 of the dressing when removing the ureteral stent 2, while also saving materials.

[0032] Release paper layer 106 is a ring-shaped release paper with a notch, the notch penetrating the ring-shaped release paper radially upwards.

[0033] The tube section 102 is a tapered structure that is narrow at the top and wide at the bottom.

[0034] The inner diameter of the upper opening 101 of the tube 102 is not less than 5 cm; the inner diameter of the lower opening 103 of the tube 102 is not less than 10 cm. This ensures that when the adhesive tape is applied to the wound 3, the complete wound 3 can be seen through the lower opening 103.

[0035] The axial length of the perforation section 102 is not less than 10cm. This ensures that when the perforation section 102 is vertical, it can completely cover the curled section at the end of the ureteral stent 2.

[0036] The perforated section can be transparent for easy observation.

[0037] The perforation section 102 includes an inner and outer absorbent layer and a waterproof membrane layer, with the absorbent layer fixed to the inner wall of the waterproof membrane layer. The absorbent layer absorbs urine when it splashes. The waterproof membrane layer prevents urine penetration. The absorbent layer is made of absorbent cotton or absorbent resin. The waterproof membrane layer can be made of polyethylene film. Alternatively, the perforation section 102 can be made of adhesive tape, with the adhesive layer of the tape located on the inner side of the perforation section 102 and bonded to the absorbent layer. This facilitates the absorption of urine from the old ureteral stent 2 on the inner side.

[0038] The working principle of this utility model is as follows:

[0039] Before removing the ureteral stent 2, peel off the release paper layer at the bottom of the attachment 104 so that the adhesive side of the bottom of the adhesive tape layer 105 can adhere to the skin around the wound 3. During this process, it is necessary to ensure that the wound 3 is completely exposed within the range of the lower opening 103 of the tube 102 to facilitate the operation of medical personnel.

[0040] Before removing the old ureteral stent 2, pinch the upper opening 101 of the perforation portion 102 with moderate force, so that the upper opening 101 of the perforation portion 102 can fit tightly with the ureteral stent 2 while allowing the ureteral stent 2 to be slowly pulled out. When the end of the ureteral stent 2 is pulled out of the incision 3, its end returns to its curled shape, and splashed urine will be absorbed by the absorbent layer on the inner wall of the perforation portion 102. After removing the ureteral stent 2, to prevent urine dissemination, the ureteral stent 2 is not completely pulled out of the perforation portion 102. The adhesive side of the bottom of the adhesive tape layer 105 is peeled off the skin, and the lower opening 103 of the perforation portion 102 (that is, the perforation of the attachment portion) is pinched tightly to wrap around the end of the ureteral stent 2. The adhesive tape layer 105 is used to adhere, wrap, and fix the end of the ureteral stent 2. The ureteral stent 2 together with the adhesive base 1 is placed in the medical waste bin. This can prevent urine dissemination that may occur during the transfer of the ureteral stent 2.

[0041] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
