Description

Technical Field

[0001] This utility model relates to the field of medical and nursing technology, specifically to a stoma base plate that can be adapted to various catheters. Background Technology

[0002] In the field of medical care, especially for patients with stomas, it is often necessary to insert drainage tubes, feeding tubes and other catheters into the body through the stoma. In particular, when patients have stoma stenosis, stoma edema or poor bowel contents drainage, it is often necessary to temporarily insert a catheter into the intestinal lumen through the stoma to decompress or drain, thereby relieving symptoms such as stoma obstruction and bloating.

[0003] The stable fixation of the catheter is crucial, as it not only affects the treatment or drainage effect, but also directly impacts the patient's comfort, the health of the skin around the stoma, and the control of infection risk.

[0004] However, existing stoma baseplates are generally limited to fixing stoma bags of a fixed diameter, and do not provide specialized structural support for the temporary placement and fixation of catheters with mismatched diameters (smaller than the stoma baseplate diameter). Currently, traditional fixation methods mostly use medical tape or dressings in conjunction with the baseplate for simple fixation. These methods have several drawbacks. First, they are not secure and are prone to falling off. They are also not adjustable, and the catheters are prone to displacement or slippage due to patient movement or changes in body position, affecting the safety of medical procedures. Second, frequent application and removal of tape or dressings can damage the delicate skin around the stoma, causing contact dermatitis, increasing patient suffering, and leaving adhesive residue. It is difficult to quickly and accurately restore the original tightness of fixation after care, and they cannot be reused.

[0005] Therefore, there is an urgent need for a device that can securely, flexibly, and conveniently fix the catheter while protecting the surrounding skin. Utility Model Content

[0006] To achieve the above objectives, the present invention provides the following technical solution: a stoma base plate that can be adapted to various catheters, including a base plate, the base plate including a plastic plate, a backing board fixed on the back of the plastic plate, a connecting groove being provided at the center of both the plastic plate and the backing board, and a connecting ring being fixed in the connecting groove.

[0007] The chassis has a fixing component mounted on the front, which includes a covering mechanism mounted on the front of the connecting ring for opening and closing the connecting groove and fixing the conduit.

[0008] The fixing components also include two sets of rope winding mechanisms mounted on the front of the plastic disc for controlling the opening and closing of the covering mechanism.

[0009] Preferably, the covering mechanism includes two sets of elastic films symmetrically fixed on the front side of the connecting ring. The front ends of the two sets of elastic films are rolled, and two binding ropes are movably sleeved inside, namely: soft rope one and soft rope two.

[0010] Preferably, each winding mechanism includes a base fixed to the front of the plastic disc and located on one side of the connecting ring, with a winding button movably connected to the base, and the two ends of soft rope one and soft rope two fixed to the side of the corresponding winding button.

[0011] Preferably, a connecting rod is fixed to the shaft core of the base, and a sleeve is fixed to the front end of the connecting rod. The shaft core at the tail end of the rewind button has a sleeve hole, the front end of the connecting rod passes through the sleeve hole, and the sleeve is movably sleeved in the sleeve hole.

[0012] Preferably, a reset mechanism is installed inside the sleeve hole. The reset mechanism includes a first washer and a second washer movably connected inside the sleeve hole. A tension spring is fixed to the opposite surface of the first washer and the second washer. The back of the first washer is attached to the inside of the sleeve hole and close to the wall at one end of the base. The back of the second washer is attached to the front of the sleeve button.

[0013] Preferably, the base has multiple positioning holes distributed circumferentially around the side of the connecting rod on the front side, and a positioning protrusion is provided at the tail end of the rewind button and at the off-axis core position, with the front end of the positioning protrusion inserted into the corresponding positioning hole.

[0014] Compared with the prior art, this utility model provides a stoma base plate that can be adapted to various catheters, and has the following beneficial effects:

[0015] 1. This stoma baseplate, which is compatible with various catheters, features a wrapping mechanism and a cord retraction mechanism. It utilizes a soft, elastic membrane to actively wrap and tighten the catheter under the traction of a restraint cord. The rotatable design of the retraction knob allows medical staff to effectively and flexibly adjust the tightness of the cord, thereby adapting to catheters of different diameters and providing just the right clamping force. At the same time, the locking mechanism reliably maintains this fixed state, ensuring the stability of the catheter position during various daily activities and greatly reducing the risk of unplanned catheter removal.

[0016] 2. This stoma baseplate, which is compatible with various catheters, fits tightly against the outer wall of the catheter through an elastic film, forming a flexible, sealed covering area above the connection groove. This effectively prevents stoma excretions or secretions from seeping out along the outer wall of the catheter and avoids the risk of infection from contact between the stoma and the outside world. This method is more reliable than static adhesive tape and can be repeatedly used, significantly reducing the leakage rate, protecting the skin around the stoma, reducing skin complications and the chance of infection, and improving the patient's quality of life.

[0017] 3. This stoma baseplate, which is compatible with various catheters, uses an elastic membrane and soft rope made of soft, biocompatible materials to cover the catheter. This avoids hard scratching or pressure on the catheter surface, reducing the risk of physical damage to the catheter. At the same time, this fixation method avoids repeated sticking and tearing of adhesive tape on the skin, fundamentally reducing the occurrence of adhesive-related skin damage and bringing greater comfort to patients.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1 - Figure 4 As shown, the stoma base plate that can be adapted to various catheters proposed in this embodiment includes a base plate 1. The base plate 1 is composed of a plastic plate 11 and an adhesive backing plate 12. The plastic plate 11 is made of a medical polymer material with support and protection (its shape and size can be designed to fit the contour of the human stoma site, which is circular in this case), which provides protection for the stoma. The adhesive backing plate 12 is fixedly attached to the back of the plastic plate 11 (i.e., the direction close to the skin). The back of the adhesive backing plate 12 is coated with a medical pressure-sensitive adhesive layer and covered with release paper so that it can be pasted and fixed to the skin at the edge of the patient's stoma during use.

[0027] Both the plastic disc 11 and the adhesive backing plate 12 have connecting grooves 13 of the same size at their center for the passage of ostomy or catheters. A connecting ring 14 is integrally formed and fixed to the inner edge of the connecting groove 13 of the plastic disc 11. The other end of the connecting ring 14 is rolled and wrapped around the inner edge of the connecting groove 13 of the adhesive backing plate 12 to ensure the alignment of the two connecting grooves 13. The connecting ring 14 is made of the same medical plastic as the plastic disc 11 to provide a stable installation base for the subsequent fixation component 2.

[0028] A fixing component 2 is mounted on the front of the chassis 1. This component includes a single covering mechanism 21 and two rope winding mechanisms 22.

[0029] The covering mechanism 21 includes two sets of symmetrically arranged elastic films 211. The tail ends of the two sets of elastic films 211 (near the connecting ring 14) are respectively fixedly connected to the two sides of the front of the connecting ring 14 (the film is fixed along the path of the ring and is in an arc shape). The elastic film 211 is preferably made of soft medical silicone or polyurethane film, which has good elasticity and biocompatibility.

[0030] Both sets of elastic membranes 211 have their free ends processed into rolled edges to form hollow cavities. Inside the cavities, two flexible restraint ropes, namely rope one 212 and rope two 213, are movably threaded. Rope one 212 and rope two 213 are made of medical silk thread, and the ends of the two restraint ropes face opposite directions. By pulling or loosening the two restraint ropes, the expansion and contraction of the two sets of elastic membranes 211 can be controlled. When expanded, the stoma can be exposed for intubation and installation of the ostomy bag. When contracted, the connecting groove 13 is closed and the catheter passing through it is clamped and fixed.

[0031] The two sets of rope winding mechanisms 22 are respectively installed on the front of the plastic disc 11 and located on both sides of the connecting ring 14. Each set of rope winding mechanisms 22 includes a base 221 fixed on the plastic disc 11 and a winding button 222 rotatably connected to the base 221.

[0032] A connecting rod 2211 extending forward is fixed at the center of the front of the base 221. A sleeve 2212 with a diameter larger than the rod body is fixed at the front end of the connecting rod 2211. At the same time, multiple positioning holes 2213 are equally spaced around the connecting rod 2211 on the front of the base 221.

[0033] The rewind knob 222 is cylindrical with a concave shape towards the center on its side. A sleeve hole 2221 is provided at the center of its tail end (the end closest to the base). During installation, the front end of the connecting rod 2211 passes through this sleeve hole 2221, and the sleeve 2212 is accommodated in the sleeve hole 2221 (the diameter of the knob body matches the inner diameter of the hole). This allows the rewind knob 222 to rotate stably relative to the base 221 and the connecting rod 2211, without restricting its axial displacement. At the same time, a positioning protrusion 2222 is provided on the off-axis core of the tail end face of the rewind knob 222. When the rewind knob 222 moves forward axially, the positioning protrusion 2222 disengages from the current positioning hole 2213. After rotating the rewind knob 222 to the appropriate number of winding turns, the rewind knob 222 moves backward axially, so that the positioning protrusion 2222 is inserted into the corresponding positioning hole 2213 to fix the current position.

[0034] To achieve the automatic reset effect of the rewind button 222, a reset mechanism 23 is installed inside the sleeve hole 2221. This mechanism includes a first washer 231 and a second washer 232 movably connected inside the sleeve hole. A tension spring 233 is fixed to the opposite surfaces of the first washer 231 and the second washer 232. Under the elastic release force of the spring, the two washers are pushed to move in opposite directions, so that the back of the first washer 231 is in contact with the inside of the sleeve hole 2221 and close to the wall of one end of the base 221, while the back of the second washer 232 remains in contact with the wall. On the front of the sleeve 2212, while maintaining a certain resistance, when the rewind button 222 moves axially forward, the sleeve 2212 drives the second washer 232 to move closer to the first washer 231, pressing the tension spring 233. When the rewind button 222 is released (hand is removed), the spring is fully released, pushing the second washer 232 and the sleeve 2212 to move away from the first washer 231, so that the rewind button 222 is reset, thereby driving the positioning protrusion 2222 at the tail end to be inserted into the corresponding positioning hole 2213.

[0035] The working principle of the stoma base plate that can be adapted to various catheters proposed in this embodiment is as follows: When the device is in use, the base plate 1 is firmly attached to the skin around the patient's stoma by the adhesive backing plate 12. The stoma or catheter passes through the connecting groove 13 in the center of the base plate 1. At this time, the two sets of elastic films 211 of the covering mechanism 21 are in a naturally closed state. Under the pull generated by the winding of the binding rope (soft rope one 212 and soft rope two 213), the elastic film 211 closes from the edge of the connecting groove 13 to the center, thereby gently and firmly covering and tightening the catheter passing through it, realizing the fixation and sealing of the catheter, and preventing displacement, leakage and stoma infection.

[0036] When it is necessary to change the ostomy bag or perform ostomy care, the operator needs to release the catheter fixation. At this time, pinch the rewind knobs 222 of the two rope rewinding mechanisms 22 respectively, and pull them slightly forward along the axis to make the positioning protrusion 2222 at the end of the rewind knob 222 disengage from the current positioning hole 2213 of the base 221. At the same time, the tension spring 233 of the reset mechanism 23 is compressed and stored. While maintaining the pulled-out state, rotate the rewind knob 222 in the opposite direction to release the restraint rope (soft rope one 212 or soft rope two 213) wrapped around it. Since the ends of the two restraint ropes face opposite directions, they each control an elastic film 211. The simultaneous release of the restraint ropes will cause the two elastic films 211 to unfold outwards on their own elasticity, thereby fully opening the space above the connecting groove 13, fully exposing the ostomy and catheter, which is convenient for nursing operations.

[0037] After the nursing care is completed, the catheter needs to be re-secured. At this time, rotate the rewind knob 222 in the forward direction to rewind the restraint rope. When the restraint rope is tightened, it will pull the free ends of the two elastic films 211 toward the center and gradually close and cover the catheter. The number of winding turns can be adjusted to a suitable tightness according to the catheter diameter and the required clamping force. After adjustment, release the rewind knob 222. Under the release force of the tension spring 233 that has been compressed in the reset mechanism 23, the rewind knob 222 will automatically return to its axial direction and reset, so that the positioning protrusion 2222 at its tail end is inserted into the corresponding positioning hole 2213, thereby achieving mechanical locking and completing the effective fixation of the catheter.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
