Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to an integrated urethral stent catheter. Background Technology

[0002] Bladder cancer, such as rectal cancer invading the bladder, neurological dysfunction leading to bladder paralysis, urethral sphincter dysfunction, congenital malformations, urethral tumors, trauma, etc., can render the original urinary tract unusable. In such cases, urinary tract diversion is required. This involves making an incision in the skin in the abdomen and connecting the original urinary tract to the ileum. One end of this ileum is then sutured closed, and the other end is pulled to the abdomen, opened, and sutured to the surface of the abdomen, thus completing the surgical stoma.

[0003] To prevent the urethrostomy from closing during postoperative recovery and to avoid skin adhesion at the stoma site, medical staff usually place a catheter at the urethrostomy site. However, in actual use, because the catheter wall is smooth, the catheter may dislodge outward or inward due to the patient's daily activities such as running, bending over, turning over while sleeping, and curling up the lower abdomen while sitting. This not only fails to effectively prevent adhesion, but also makes it difficult to remove the catheter if it falls into the body.

[0004] Therefore, how to design an integrated urethral stent catheter that can solve the above-mentioned technical problems is a problem that needs to be solved. Utility Model Content

[0005] To address the aforementioned problems, the purpose of this invention is to provide an integrated urethral stent catheter that solves the problem of existing catheters easily falling out.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: It includes a support fixing ring movably connected to the stoma base; a pair of connecting components are symmetrically fixed inside the support fixing ring, and a short tube is fixedly connected between the two sets of connecting components, with the short tube located in the middle of the support fixing ring; the connecting components include a front elastic connecting strip fixedly connected to the support fixing ring, a rear elastic connecting strip fixedly connected to the short tube, and a spring connecting the front and rear elastic connecting strips; the free ends of the front and rear elastic connecting strips are respectively fixedly fitted with a first connecting tube and a second connecting tube, and both ends of the spring are respectively fixedly connected to the first and second connecting tubes; a plurality of connecting buckles are equidistantly arranged on the outer peripheral wall of the first connecting tube along its length direction, and a connecting plate is rotatably arranged on the outer peripheral wall of the second connecting tube; the connecting strip has a plurality of connecting openings corresponding to the positions of the plurality of connecting buckles; a ring of fastening flange is vertically fixed on one side end face of the stoma base, and the upper end face of the fastening flange has an installation groove matching the shape and size of the support fixing ring, and the inner side of the fastening flange has an opening for the front elastic connecting strip to pass through.

[0007] Furthermore, the ostomy bag opening is provided with a connecting ring, the inner side wall of the connecting ring is provided with an internal thread, the outer side wall of the fastening flange is fixed with an external thread, and the ostomy bag is threadedly connected to the ostomy base plate.

[0008] Furthermore, the inner top of the fastening flange, corresponding to the mounting groove, is hinged to an arc-shaped pressure cap via an arc-shaped hinge.

[0009] Furthermore, an adhesive layer matching the size of the stoma base is fixed on the end face of the stoma base away from the fastening flange, and a protective paper matching the size of the adhesive layer is pasted to the bottom end of the adhesive layer.

[0010] This utility model has the following beneficial effects:

[0011] 1. This utility model is equipped with a bracket fixing ring. By stretching and pressing the rear elastic connecting strips of the connecting components on both sides, the position of the short tube can be adjusted. The connecting holes on the connecting plate are connected to the connecting buckles one by one to fix the position of the short tube. On the one hand, it can effectively fix the short tube and prevent it from slipping off. On the other hand, it allows the patient to flexibly adjust the position of the short tube according to the stoma position (when the stoma base plate is pasted, the stoma is not necessarily in the exact center of the stoma base plate), so as to avoid the short tube pulling on the skin around the stoma and causing discomfort to the patient.
