Description

Technical Field

[0001] This utility model relates to the field of urinary care technology, and in particular to a urinary care drainage anti-bend device. Background Technology

[0002] Urology is a branch of medicine that specializes in the study of the male and female urinary and reproductive systems. It is a subspecialty derived from surgery. The male urinary and reproductive systems are inseparable, while the female urinary tract opens into the vulva. Regardless of gender, the urinary and reproductive tracts are closely related, and diseases of both often affect each other.

[0003] In clinical practice, indwelling catheterization is a common method for resolving urinary obstruction in patients. Catheterization involves inserting a catheter through the urethra into the bladder to drain urine. The purpose is to relieve urinary retention, obtain uncontaminated urine samples for examination, measure residual urine, assess bladder temperature, capacity, and pressure, and inject contrast agents or medications to aid in diagnosis or treatment. Drainage tubes are primarily inserted after surgery to drain urine.

[0004] Patent document CN221600980U discloses an anti-bending drainage tube. By setting a lower sheath and an upper sheath, and through the cooperation of connecting posts, a cavity, and a first spring, the gap between the lower and upper sheaths can be widened and clamped at the front end of the drainage tube body. This detachable structure effectively supports and protects the end of the drainage tube body at the wound site, preventing bending and deformation due to patient movement and greatly ensuring the drainage effect of the drainage tube body. By setting arc-shaped support plates on both sides of the lower sheath, the lower sheath can be further supported and fixed, allowing it to be stably connected to the patient's skin, thus preventing rotation of the protective mechanism and greatly improving stability. The support posts and elastic components on the support plates allow the support plates to better adhere to the patient's skin and reduce rigid compression between the support plates and the skin, greatly improving the effectiveness of the device.

[0005] Although the aforementioned anti-bending drainage tube can solve the corresponding technical problems, the upper and lower protective sleeves of its protective mechanism use a combination of connecting columns, grooves, and a first spring to clamp the drainage tube body. However, after prolonged use, the spring will experience mechanical fatigue, making it difficult to return to the initial state during reset. This reduces the clamping force on the drainage tube body, thereby reducing the support and protection effect on the end of the drainage tube body at the wound.

[0006] Therefore, a urinary care drainage anti-breakage device is proposed. Utility Model Content

[0007] The purpose of this invention is to provide a urinary care drainage anti-bend device to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, the main technical solutions adopted by this utility model include:

[0009] A urinary care drainage anti-bend device, comprising:

[0010] A limiting sleeve fitted onto the surface of a urinary catheter has several annularly distributed fixing components inside its cavity to restrict the catheter. The outer surface of the limiting sleeve is threaded with an adjusting component for synchronously contracting or expanding the fixing components.

[0011] The fastener includes a clamping plate located inside the cavity of the limiting sleeve, and a rubber pad is fixedly connected to the inner wall surface of the clamping plate;

[0012] The adjusting component includes a threaded sleeve that is threaded onto the outer surface of the limiting sleeve. A linkage component is provided between the inner wall of the threaded sleeve and each clamping plate. A through groove is provided on the surface of the limiting sleeve for the linkage component to pass through.

[0013] As a preferred technical solution, both ends of the clamp plate away from the rubber pad are integrally formed with lugs. One side of the lugs extends through to the outside of the limiting sleeve. The limiting sleeve has a through hole for the lugs to pass through, and the inner wall of the through hole is slidably connected to the surface of the corresponding lug.

[0014] As a preferred technical solution, the linkage includes a connecting rod rotatably connected to the side of the clamping plate away from the rubber pad, the other end of the connecting rod passing through the inner cavity of the through groove and rotatably connected to a protrusion, and an annular groove being formed on the inner wall of the threaded sleeve, with the protrusion being movably embedded in the inner wall of the annular groove and slidably connected.

[0015] As a preferred technical solution, the opening width of the annular groove cross-section is smaller than the width of the protrusion cross-section.

[0016] As a preferred technical solution, the outer surface of the threaded sleeve is fixedly connected with a number of equidistant convex strips.

[0017] As a preferred technical solution, the threaded sleeve is located between two lugs on the clamping plate, and the length of the threaded sleeve is less than the distance between the two lugs on the clamping plate.

[0018] As a preferred technical solution, a rubber ring is fixedly connected to both ends of the inner wall surface of the limiting sleeve, and one end of the rubber ring is in contact with the end of the clamping plate.

[0019] As a preferred technical solution, a support plate is fixedly connected to both sides of the bottom of the limiting sleeve, and the support plate has an arc-shaped structure.

[0020] This utility model has at least the following beneficial effects:

[0021] This application utilizes a rotating adjusting component to move several fixing components synchronously. This not only secures the drainage tube, providing support and protection for the proximal end of the tube at the wound site, preventing bending or detachment due to traction, but also accommodates drainage tubes of different diameters. This expands the applicability of the urinary care drainage anti-bend device. Eliminating the need for a spring structure improves the clamping effect on the drainage tube, preventing structural failure, and reduces the number of steps required to fix the tube, eliminating the need for subsequent tape wrapping and securing.

Detailed Implementation

[0028] 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.

[0029] Please see Figures 1-3This utility model provides a urinary care drainage anti-bend device, including a limiting sleeve 100 fitted onto the surface of a urinary drainage tube. The inner cavity of the limiting sleeve 100 has several ring-shaped, equidistantly distributed fixing members 200 for restricting the drainage tube. The outer surface of the limiting sleeve 100 is threadedly provided with an adjusting member 300 for synchronously contracting or expanding the fixing members 200. The adjusting member 300 includes a threaded sleeve 310 threaded onto the outer surface of the limiting sleeve 100. A linkage member is provided between the inner wall of the threaded sleeve 310 and each fixing member 200. A through groove 110 is provided on the surface of the limiting sleeve 100 for the linkage member to pass through. The size of the limiting sleeve 100 matches the size of the urinary drainage tube.

[0030] The fixing member 200 includes a clamping plate 210 located in the inner cavity of the limiting sleeve 100. A rubber pad 220 is fixedly connected to the inner wall of the clamping plate 210. A linkage member is located between the clamping plate 210 and the threaded sleeve 310. By rotating the threaded sleeve 310, the threaded sleeve 310 moves on the surface of the limiting sleeve 100. The linkage member can drive the fixing member 200 to move toward or away from the central axis of the limiting sleeve 100, thus enabling the clamping or loosening of drainage tubes of different sizes.

[0031] The clamping plate 210 has lugs 211 integrally formed at both ends on the side away from the rubber pad 220. One side of the lugs 211 extends through to the outside of the limiting sleeve 100. The limiting sleeve 100 has a through hole for the lugs 211 to pass through. The inner wall of the through hole is slidably connected to the surface of the corresponding lugs 211. Through the cooperation of the lugs 211 and the through hole, the clamping plate 210 can be guided, so that the clamping plate 210 can move stably and avoid shaking or displacement.

[0032] The linkage includes a connecting rod 320 rotatably connected to the side of the clamping plate 210 away from the rubber pad 220 via a rotating shaft. The other end of the connecting rod 320 passes through the inner cavity of the through groove 110 and is rotatably connected to a protrusion 330 via a rotating shaft. The cross-section of the protrusion 330 is any one of circular, T-shaped or dovetail shape. The inner wall of the threaded sleeve 310 is provided with an annular groove 340. The protrusion 330 is movably embedded in the inner wall of the annular groove 340 and slidably connected. The linkage enables the linkage operation between the fixing member 200 and the threaded sleeve 310 and can change the direction of force so as to achieve the effect of moving several fixing members 200 in one step.

[0033] The opening width of the annular groove 340 is smaller than the width of the protrusion 330, so that the protrusion 330 is always movable and embedded in the inner cavity of the annular groove 340, preventing excessive movement and detachment, and ensuring that the fastener 200 is always linked.

[0034] The outer surface of the threaded sleeve 310 is fixedly connected with several equidistant convex strips 311. The convex strips 311 can increase the friction between the threaded sleeve 310 and the hand, play an anti-slip role, and facilitate the rotation of the threaded sleeve 310.

[0035] The threaded sleeve 310 is located between the two lugs 211 on the clamping plate 210, and the length of the threaded sleeve 310 is less than the distance between the two lugs 211 on the clamping plate 210, so as to ensure that the threaded sleeve 310 has enough room to move and avoid the lugs 211 from blocking the threaded sleeve 310.

[0036] A rubber ring 400 is fixedly connected to both ends of the inner wall of the limiting sleeve 100. One end of the rubber ring 400 contacts the end of the clamp 210. The rubber ring 400 can shield and protect the two ends of the limiting sleeve 100, preventing the drainage tube from directly contacting the ends of the limiting sleeve 100, making it less likely for the drainage tube to be blocked or bent.

[0037] The limiting sleeve 100 has a support plate 500 fixedly connected to both sides of its bottom. The support plate 500 has an arc-shaped structure. The support plate 500 can stably fit the limiting sleeve 100 to the patient's body to prevent the urinary care drainage anti-fold device from rotating.

[0038] The working principle of this utility model is as follows: The end of the drainage tube passes through the limiting sleeve 100. One hand holds the limiting sleeve 100, while the other hand rotates the threaded sleeve 310, causing the threaded sleeve 310 to drive the annular groove 340 to rotate synchronously. Under the action of the thread, the threaded sleeve 310 moves on the surface of the limiting sleeve 100, causing the inner wall of the annular groove 340 to push the protrusion 330 to move synchronously. The protrusion 330 drives one end of the connecting rod 320 to move via a rotating shaft. Since the length of the connecting rod 320 remains constant, the angle of inclination of the connecting rod 320 changes. The other end of the connecting rod 320 drives the clamping plate 210 to move towards the center of the limiting sleeve 100 via the rotating shaft (e.g., ...). Figure 3 As shown, the clamp 210 drives the rubber pad 220 and the lug 211 to move synchronously. The lug 211 slides in the through hole until the rubber pad 220 contacts the surface of the drainage tube to fix the drainage tube. Therefore, the proximal end of the drainage tube at the wound can be supported and protected by the limiting sleeve 100 and the fixing member 200 to prevent bending and deformation due to patient movement, thus ensuring the drainage effect of the drainage tube.

[0039] All parts not described in this utility model are the same as or can be implemented using existing technology. Although embodiments of this utility model 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 this utility model, the scope of which is defined by the appended claims and their equivalents.
