Description

Technical Field

[0001] The utility model belongs to the technical field of medical instruments, and in particular relates to a urinary catheter fixing device. Background Art

[0002] A urinary catheter is a tube that is inserted into the bladder through the urethra to drain urine. It is a tube made of natural rubber, silicone rubber or polyvinyl chloride (PVC) and can be inserted into the bladder through the urethra to drain urine. After the catheter is inserted into the bladder, there is an air bag near the tip of the catheter to fix the catheter in the bladder and prevent it from falling out. The drainage tube is connected to a urine bag to collect urine.

[0003] At present, there is not much difference in the clinical prevention measures of CAUTI in China in terms of urethral disinfection and indwelling urinary catheter care, but there is a big difference in catheter fixation. The role of the catheter fixation device is to ensure the stability of the catheter position during the operation to avoid surgical failure caused by catheter sliding. There are two main ways to fix the catheter, namely the traditional fixation method and the 3M fixation patch. The traditional fixation method is to fix the catheter to the bed sheet with a rubber band and a safety pin, and the 3M fixation patch is to fix the catheter to the patient's skin. The former may cause accidental needle sticks, and the latter will damage the patient's skin. In addition, the fixing strength of both is poor, which can easily cause catheter traction. Utility Model Content

[0004] The utility model provides a urinary catheter fixing device, aiming to solve the problem to be solved by the above-mentioned background technology.

[0005] The utility model is implemented as follows: a catheter fixing device comprises a sleeve cap, a threaded tube, a clamping claw and a locking cap, wherein the sleeve cap is provided with a through hole for the catheter to pass through, the sleeve cap is connected to the threaded tube, the clamping claw is connected to one end of the threaded tube away from the sleeve cap, the threaded tube is provided with an external thread, the inner wall of the locking cap is provided with an internal thread matching the external thread, and a guiding inclined surface is provided inside the locking cap.

[0006] Optionally, the sleeve cap is hemispherical.

[0007] Optionally, a locking ring is also provided on the sleeve cap.

[0008] Optionally, a hand-held portion is further included, and the hand-held portion is arranged at the connection between the sleeve cap and the threaded tube.

[0009] Optionally, at least two first protrusions are provided on the handheld portion.

[0010] Optionally, the clamping claw is composed of a plurality of strip-shaped clamping pieces.

[0011] Optionally, the clamping claw and the threaded tube are an integrated structure.

[0012] Optionally, a protective sleeve is also included, and the protective sleeve is arranged in the clamping claw.

[0013] Optionally, at least two second protrusions are provided on the locking cap.

[0014] Optionally, one end of the locking cap away from the sleeve cap is hemispherical.

[0015] The beneficial effect achieved by the utility model is that a catheter fixing device realizes stable fixation of the catheter through the combined design of a cap, a threaded tube, a clamping claw and a locking cap. Compared with traditional safety pins or 3M fixing stickers, the catheter fixing device can more reliably fix the catheter and reduce the risk of catheter sliding during surgery. Furthermore, the catheter fixing device effectively prevents the catheter from moving in the urethra through the clamping effect of the clamping claw on the outer wall of the catheter. In addition, the catheter fixing device is directly fixed to the glans penis through the cap, rather than on the skin or bed sheets, so it can reduce the risk of skin damage and accidental needle stick injuries caused by skin adhesion or acupuncture.

[0022] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps, operations, components or modules is not limited to the listed steps, operations, components or modules, but may optionally include steps, operations, components or modules that are not listed, or may optionally include other steps, operations, components or modules that are inherent to these processes, methods, products or devices.

[0024] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0025] like Figures 1 to 2 As shown, an exemplary embodiment of a catheter fixing device includes a cap 1, a threaded tube 2, a clamping claw 3 and a locking cap 4, the cap 1 is provided with a through hole 12 for the catheter to pass through, the cap 1 is connected to the threaded tube 2, the clamping claw 3 is connected to one end of the threaded tube 2 away from the cap 1, the threaded tube 2 is provided with an external thread, the inner wall of the locking cap 4 is provided with an internal thread matching the external thread, and a guiding inclined surface 42 is provided inside the locking cap 4.

[0026] The cap 1 can be made of, but not limited to, silicone, polyurethane, polytetrafluoroethylene, polymethyl methacrylate, polycaprolactone, or polylactic acid. In this embodiment, the cap 1 is made of silicone, and the silicone has good flexibility and suitable elasticity, can fit closely to human tissue, and is skin-friendly. The temperature resistance and chemical stability of silicone are also very good, and it is suitable for long-term contact with the human body. The opening of the cap away from the threaded tube 2 is circular, and the diameter of the circle is 3 cm.

[0027] When in use, firstly, the catheter is passed through the cap 1, the threaded tube 2, the clamping claw 3 and the locking cap 4, and the catheter is inserted into the bladder through the urethra. After the catheter is placed in a suitable position, the cap 1 is put on the glans penis, and the cap 1 made of silicone material will be fastened to the glans penis, and the threaded tube 2 and the clamping claw 3 are also fixed to the glans penis along with the cap 1.

[0028] The locking cap 4 is threadedly connected to the threaded tube 2, and the locking cap 4 is continuously rotated, and then the guide bevel 42 contacts the clamping claw 3. As the locking cap 4 continues to rotate, the guide bevel 42 fastens the clamping claw 3 to the outer wall of the catheter, thereby fixing the catheter.

[0029] The combined design of the cap 1, the threaded tube 2, the clamping claw 3 and the locking cap 4 achieves stable fixation of the catheter. Compared with traditional safety pins or 3M fixing stickers, the catheter fixing device can fix the catheter more reliably and reduce the risk of catheter sliding during surgery. Furthermore, the catheter fixing device effectively prevents the catheter from moving in the urethra through the clamping effect of the clamping claw 3 on the outer wall of the catheter. In addition, the catheter fixing device is directly fixed to the glans penis through the cap 1, rather than on the skin or bed sheets, so it can reduce the risk of skin damage and accidental needle stick injuries caused by skin adhesion or acupuncture.

[0030] As an example, the cap 1 is hemispherical. The hemispherical design is more consistent with the natural shape of the glans penis, and thus can provide better fit and comfort. Since the shape of the cap 1 fits the glans penis, the hemispherical cap can be more effectively kept in place, reducing sliding and displacement during activities or long-term use, thereby improving the stability of the overall fixation.

[0031] As an example, the cap 1 is also provided with a locking ring 11. The locking ring 11 can fit tightly between the glans penis and the concave position of the penis itself, providing additional fixing force to ensure that the cap 1 does not slide or fall off during use. When in use, the cap 1 is fixed more tightly to the glans penis.

[0032] As an example, a urinary catheter fixing device further includes a hand-held portion 5, and the hand-held portion 5 is arranged at the connection between the cap 1 and the threaded tube 2. When in use, it is convenient for medical staff to hold it.

[0033] As an example, at least two first protrusions 51 are provided on the hand-held portion 5. During use, the medical staff holds the hand-held portion 5 with one hand and rotates the locking cap 4 with the other hand. The setting of the first protrusions 51 can effectively increase the friction between the human hand and the hand-held portion 5, and avoid the problem of slipping between the human hand and the hand-held portion 5.

[0034] As an example, the clamping claw 3 is composed of a plurality of strip-shaped clamping pieces 31. When in use, as the locking cap 4 is tightened, the strip-shaped clamping piece 31 is pressed by the guide inclined surface 42, so that the strip-shaped clamping piece 31 is closely attached to the urinary catheter.

[0035] As an example, the clamping jaw 3 is an integral structure with the threaded tube 2. The integral design of the clamping jaw 3 and the threaded tube 2 means that there is no seam or connection point between the clamping jaw 3 and the threaded tube 2, which can reduce potential breaking points and improve the strength and durability of the overall structure.

[0036] As an example, a catheter fixing device further includes a protective sleeve 6, which is disposed in the clamping claw 3. The protective sleeve 6 may be made of, but is not limited to, polyetheretherketone, polytetrafluoroethylene, rubber, and resin. In the process of clamping the catheter by the clamping claw 3, the protective sleeve 6 is located between the outer wall of the catheter and the strip clamping piece 31, which can effectively prevent the strip clamping piece 31 from clamping the outer wall of the catheter or causing damage to the outer wall of the catheter during the clamping process.

[0037] As an example, at least two second protrusions 41 are provided on the locking cap 4. In the process of rotating the locking cap 4, the locking cap 4 needs to be pinched to rotate. The setting of the second protrusions 41 is convenient for the human hand to drive the locking cap 4. In the process of rotation, the second protrusions 41 can be directly moved, which effectively avoids slipping during rotation.

[0038] As an example, the end of the locking cap 4 away from the cover cap 1 is hemispherical. The hemispherical shape makes the shape formed between the locking cap 4 and the catheter smoother. The hemispherical design has no sharp edges, so that the friction between the locking cap 4 and the bedding or clothing can be reduced during use.

[0039] The exemplary embodiments of the present application may be combined with each other, and the exemplary embodiments obtained by the combination also fall within the scope of the present application.

[0040] This application uses specific examples to illustrate the principles and implementation methods of this application. The description of the above embodiments is only used to help understand the method and core idea of ​​this application. At the same time, for technical personnel in this field, according to the idea of ​​this application, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on this application.
