Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and particularly relates to a depth-controllable catheter with scale marks. Background Art

[0002] The indwelling catheterization technique is a method of inserting a sterile catheter through the urethra into the bladder to drain urine under strict aseptic operation, and it is a commonly used nursing operation technique in clinical practice at present.

[0003] Due to the different urethral lengths of different patient populations, when using traditional catheters with fixed lengths, problems such as inaccurate catheter insertion lengths are likely to occur, and medical staff need to repeatedly probe and operate.

[0004] Therefore, in the prior art, scales are set on the catheter, and the medical staff are assisted by the prompts of the scale marks to accurately implant the catheter length.

[0005] However, when using such a catheter with scale marks, on the one hand, due to the thinness of the catheter, the scale marks are often not easy to view; on the other hand, due to the lack of a component that can actively adjust the insertion depth, when the medical staff judge the urethral length based on experience and implant the catheter at the same depth, there is an error in judging the urethral length, resulting in the catheter being implanted too deep and touching the bladder wall, causing discomfort to the patient. Especially for child patients in the development process, the short and different urethral lengths make it easy for young doctors to have the above problems. Summary of the Utility Model

[0006] The purpose of the utility model is to provide a depth-controllable catheter with scale marks to solve the technical problems in the prior art that due to the thinness of the catheter and the lack of a backstop, the scale marks are not clear and there is an error in the implantation accuracy.

[0007] To solve the above technical problems, the utility model specifically provides the following technical solutions:

[0008] A depth-controllable catheter with scale marks includes a sleeve, the sleeve is slidably sleeved outside the catheter with scale marks, the sleeve includes a front section, a middle section and a rear section. Among them, a lens body for magnifying the scale marks is fixedly arranged on the front section, an elastic ring is sleeved outside the middle section, the elastic ring can move along the axial direction of the sleeve on the sleeve, the rear section includes a plurality of valves, the plurality of valves are circumferentially arranged at one end of the middle section, an activity gap is arranged between adjacent valves, and the ends of the plurality of valves can deflect towards the center;

[0009] The elastic ring moves to the rear section to make the ends of the valves deflect towards the center to fix the sleeve on the catheter.

[0010] As a preferred embodiment of the present utility model, each scale on the scale mark is circumferentially arranged in a ring shape on the outer wall of the urinary catheter.

[0011] As a preferred embodiment of the present utility model, the thickness of the valve gradually decreases from the end connected to the middle section to the other end.

[0012] As a preferred embodiment of the present utility model, two finger rings are symmetrically arranged on the elastic ring, the middle of the finger rings is hollowed out, and the two finger rings moving away from each other can pull the hollowed-out part in the middle of the elastic ring to expand in this direction.

[0013] As a preferred embodiment of the present utility model, one end of the urinary catheter close to the sleeve is set as an opening, and the urinary catheter introduces a guide wire into the bladder through the opening.

[0014] The present utility model has the following beneficial effects compared with the prior art:

[0015] The present utility model is provided with a sleeve on the urinary catheter. The scale mark is magnified by the lens body on the sleeve, so that the specific implantation depth of the urinary catheter can be more clearly understood during the implantation of the urinary catheter, making the implantation work more convenient and fast. And through the cooperative connection of the elastic ring and the valve, the sleeve can be fixed on the urinary catheter with self-adjustable position. On the one hand, the single implantation depth of the urinary catheter can be objectively controlled, and on the other hand, the sleeve with adjustable position also makes it more convenient and effective to adjust the implantation depth of the urinary catheter multiple times.

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] As Figure 1 shown, the present invention provides a depth-controllable catheter with scale markings, including a sleeve 1, the sleeve 1 is slidably sleeved outside the catheter 3 with scale markings 2, the sleeve 1 includes a front section 31, a middle section 32 and a rear section 33. Among them, a lens body 4 for magnifying the scale markings 2 is fixedly arranged on the front section 31, an elastic ring 5 is sleeved outside the middle section 32, and the elastic ring 5 can move along the axial direction of the sleeve 1 on the sleeve 1. The rear section 33 includes a plurality of valves 6, the plurality of valves 6 are circumferentially arranged at one end of the middle section 32, an activity gap is arranged between adjacent valves 6, and the ends of the plurality of valves 6 can deflect towards the center.

[0023] The elastic ring 5 moves to the rear section 33 to deflect the ends of the valves 6 towards the center to fix the sleeve 1 on the catheter 3.

[0024] In this device, continuous scale markings 2 are arranged on the outer wall of the catheter 3. The clear scale facilitates medical staff to accurately control the insertion depth during use. Further, a sleeve 1 is arranged on the catheter 3, and a lens body 4 for magnifying the scale markings 2 is arranged on the sleeve 1, so that the scale markings 2 on the narrow catheter 3 can be observed more clearly. In addition, each scale on the scale markings 2 is arranged circumferentially in a ring on the outer wall of the catheter 3, so that the lens body 4 at any position angle can effectively observe the scale markings 2 on the catheter 3, and the problem that the scale markings 2 are not under the lens body 4 after the sleeve 1 rotates by an angle will not occur. Make the observation more comprehensive.

[0025] During specific use, after the medical staff preliminarily determines the penetration length of the catheter 3 based on experience, the sleeve 1 is slid to this position to form a reserved part of the catheter 3 to be penetrated, which is implanted by the medical staff. Due to the limitation of the sleeve 1, it is possible to avoid discomfort caused to the patient by the catheter 3 being implanted too long due to misoperation. On the other hand, when there is an error in the urethral length evaluated by the medical staff, the actual urethral length is longer, and the reserved catheter part is shorter, at this time, the sleeve 1 is moved backward to extend the reserved implantation part.

[0026] After the above operations are completed, the position of the sleeve 1 is determined, and the urinary catheter 3 is implanted. Then, the elastic ring 5 is slid from the middle section 32 of the sleeve 1 to the rear section 33 of the sleeve 1 and sleeved outside the valve 6 to close the valve 6. The position of the sleeve 1 is fixed at the urethral orifice to prevent the urinary catheter 3 from being misinserted after implantation.

[0027] Specifically, as shown in Figure 1, the thickness of the valve 6 gradually decreases from the end connected to the middle section 32 to the other end. The head end of the valve 6 is thinner. When this device is applied to female patients, the head of the sleeve 1 formed by the thinner end of the valve 6 can be embedded into the urethral orifice of female patients to a certain extent. On the one hand, it can avoid the discomfort caused by the contact and friction between the end of the sleeve 1 and the entrance of the urethral orifice. On the other hand, after being embedded into the urethral orifice of female patients, the thicker middle section 32 at the rear can block the urethral orifice to a certain extent and act as a double barrier to prevent urine leakage when the balloon of the urinary catheter 3 is not tightly attached.

[0028] Furthermore, as Figure 1 shown, two finger rings 7 are symmetrically arranged on the elastic ring 5 in this device. The middle of the finger rings 7 is hollowed out. When the two finger rings 7 move away from each other, they can pull the hollowed-out part in the middle of the elastic ring 5 to expand in this direction.

[0029] During actual use, to facilitate the expansion of the elastic ring 5 and thus move its position (the elastic ring 5 can be made of a rubber elastic member), finger rings 7 are arranged on both sides of the elastic ring 5. By inserting fingers into the finger rings 7 and pulling outwards, the elastic ring 5 is expanded to move its position. When it is moved to the rear section 33, due to its own elastic characteristics, it forms a constraint on the valve 6 on the rear section 33, so that the valve 6 is surrounded and fixed.

[0030] In addition, one end of the urinary catheter 3 close to the sleeve 1 is set as an opening, and the urinary catheter 3 introduces a guide wire into the bladder through the opening.

[0031] The above embodiments are only exemplary embodiments of the present application and are not used to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art can make various modifications or equivalent replacements within the essence and protection scope of the present application, and such modifications or equivalent replacements should also be regarded as falling within the protection scope of the present application.
