Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a fixing device for an indwelling urinary catheter. Background Art

[0002] Indwelling urinary catheterization is a method of draining urine by inserting a sterile catheter through the urethra into the bladder under strict aseptic operation. It is a commonly used nursing operation technique in clinical practice. It is used to accurately record urine volume, measure urine specific gravity, etc. when rescuing critically ill patients or patients in shock. The end that extends outside the body is connected to a disposable urine bag.

[0003] In the prior art, indwelling urinary catheters are fixed by adhesive tape, especially the end extending outside the body generally needs to be attached to the leg by adhesive tape to prevent the indwelling urinary catheter from being pulled out of the body due to accidental contact.

[0004] However, when fixing an indwelling urinary catheter with tape, the tape is often not firmly attached to the catheter, and the indwelling urinary catheter is easily detached from the body due to strong pulling caused by accidental contact. In addition, the extension direction of the indwelling urinary catheter attached with tape is fixed, and when the extension direction of the catheter needs to be changed, the catheter is easily bent, affecting the passage. In order to improve the above situation, it is necessary to design an indwelling urinary catheter fixing device. Utility Model Content

[0005] The utility model aims to solve the technical problems in the prior art and provides a fixing device for an indwelling urinary catheter.

[0006] In order to solve the above technical problems, the technical solution of the utility model is as follows:

[0013] Furthermore, the thickness of the two ends of the coating body is smaller than the thickness in the middle.

[0020] The utility model has the following beneficial effects:

[0021] The utility model discloses a device for fixing an indwelling urinary catheter. The device fixes the indwelling urinary catheter by a columnar body. At the same time, the columnar body can adjust the routing direction of the indwelling urinary catheter by rotating, so that when the urine bag is moved externally or the urinary catheter is extended, the columnar body rotates accordingly, thereby avoiding the indwelling urinary catheter from bending and affecting the passage.

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] See also Figure 1-5 , an indwelling urinary catheter fixing device, comprising:

[0032] The covering body 1 is an arc-shaped plate-like structure, and its own curvature can better match the curvature of the leg, and thus can better fit the leg for use;

[0033] A cylindrical groove 2 is provided at the center of the lower surface of the encapsulation body 1;

[0034] The cylindrical body 3 is coaxially arranged in the cylindrical groove 2 and can rotate coaxially relative to the cylindrical groove 2. The lower end of the cylindrical body 3 is provided with a through groove 4 for accommodating the placement of the indwelling urinary catheter. Here, the cylindrical body 3 is set to an elastic rubber material. The through groove 4 has elasticity and can achieve the effect of elastically clamping the indwelling urinary catheter. At the same time, an adhesive material such as double-sided tape can be set in the through groove 4 to play an additional role of sticking and fixing the indwelling urinary catheter;

[0035] A through hole 5, which is opened at the center of the upper surface of the encapsulation body 1 and communicates with the cylindrical groove 2; and

[0036] The rotating column 6 is inserted into the through hole 5 , the lower end of the rotating column 6 is coaxially connected to the upper end surface of the cylindrical body 3 , and the upper end is connected to a circular plate 7 , and a strip-shaped rotating block 8 is provided on the upper surface of the circular plate 7 .

[0037] Specifically, after the indwelling urinary catheter is placed into the through groove 4, the circular plate 7 is rotated by the bar rotating block 8, and then the columnar body 3 is driven to rotate by the rotating column 6, so that the fixed angle of the indwelling urinary catheter can be adjusted when the extension direction of the indwelling urinary catheter is adjusted, thereby avoiding bending of the indwelling urinary catheter.

[0038] Furthermore, the thickness of the two ends of the covering body 1 is smaller than the thickness in the middle. The thicker thickness in the middle is to have enough space to accommodate the indwelling urinary catheter, and the smaller thickness at the two ends reduces the overall volume and is easier to fit on the leg for use.

[0039] Furthermore, the covering body 1 is a soft rubber plate, and can better fit the leg through its elastic deformation.

[0040] Furthermore, fan-shaped notches 9 are provided on both the front and rear sides of the covering body 1, and the fan-shaped notches 9 are connected to the cylindrical groove 2. When the indwelling urinary catheter rotates with the cylindrical body 3, in order to avoid the indwelling urinary catheter, fan-shaped notches 9 are provided on the front and rear sides of the covering body 1 to play an avoidance role.

[0041] Furthermore, a plurality of rubber spike protrusions 10 are evenly arranged on the lower surface of the circular plate 7. The friction between the rubber spike protrusions 10 and the covering body 1 prevents the circular plate 7 from rotating on its own, thereby stabilizing the position and angle of the columnar body 3, preventing the indwelling urinary catheter from rotating with the columnar body 3 without applying force, thereby stabilizing and fixing the indwelling urinary catheter.

[0042] Furthermore, connecting rings 11 are provided at both ends of the covering body 1, and elastic bands 12 are provided on the connecting rings 11;

[0043] The elastic bands 12 on the two groups of connecting rings 11 at both ends of the covering body 1 are connected by Velcro.

[0044] Specifically, after the covering body 1 is wrapped around the leg, the elastic bands 12 at both ends are tightened on the leg and connected through Velcro, which is convenient and quick, so that the covering body 1 is fixed to the leg through the elastic bands 12.

[0045] Furthermore, one end of the elastic band 12 connected to the connection ring 11 is connected by Velcro after passing through the connection ring 11. That is, one end of the elastic band 12 can be connected by Velcro after passing around the connection ring 11, so that the elastic band 12 can be disassembled and assembled on the connection ring 11, making the fixing method of the covering body 1 more flexible, thereby making the covering body 1 tightened and fixed on the leg by the elastic band 12, and the covering body 1 can be fixed on the leg directly by the adhesive tape without using the elastic band 12, and this adhesive tape fixing method is different from the adhesive tape directly fixing the indwelling urinary catheter, but after the indwelling urinary catheter is firmly fixed by the covering body 1, it is fixed by the adhesive tape, and the adhesive surface between the adhesive tape and the covering body 1 is obviously larger than the adhesive surface with the indwelling urinary catheter, so the fixation is also more secure.

[0046] In summary, the device fixes the indwelling urinary catheter through the columnar body, and the columnar body can adjust the routing direction of the indwelling urinary catheter by rotating, so that when the urine bag is moved externally or the direction of the catheter is extended, the columnar body rotates accordingly, avoiding the indwelling urinary catheter from bending and affecting the passage. The device is easy to use and quick to operate, and can better fix the indwelling urinary catheter.

[0047] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
