Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and particularly relates to an intermittent catheter with scales. Background Art

[0002] An intermittent catheter, also known as a self-catheter, is a method in which a patient or their family member inserts a catheter into the bladder through the urethra at regular intervals under clean conditions, enabling the bladder to empty urine regularly. This catheterization method is mainly applicable to patients with neurogenic bladder, that is, patients whose bladders have lost their contractile ability. Intermittent catheterization can effectively avoid problems such as bladder atrophy and recurrent urinary tract infections caused by long-term indwelling catheters, and at the same time improve the patient's quality of life and social activity ability.

[0003] Patent Application No.: 202322129834.X proposes an intermittent catheter that is convenient for controlling the insertion depth. The catheter includes a catheter body, an excretion member, and a marking member. The catheter body is formed as a hollow tubular structure, and the catheter body includes a head and a tail that communicate with each other; the excretion member is connected to the tail, and the excretion member is used to discharge human urine flowing out through the catheter body; the marking member is disposed on the outer wall of the catheter body and between the head and the tail, and the marking member is configured to move relative to the catheter body under the action of an external force. Thus, the patient can reasonably adjust the position of the marking member on the catheter body according to their own situation, and can fix the marking member on the catheter body after the position is confirmed, so that the patient can reasonably control the insertion depth of the catheter according to the memory position when using it next time, improving the convenience of using the catheter.

[0004] When this catheter is in use, there are still some deficiencies. For example, the surface of the catheter is provided with a limiting protrusion for limiting, resulting in an uneven surface of the catheter, which is likely to cause pain to the patient during insertion and affect the comfort of the patient during use. Content of the Utility Model

[0005] The purpose of the utility model is to provide an intermittent catheter with scales to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] An intermittent catheter with scales includes a catheter and an elastic belt. The top of the catheter is provided with urine drainage holes on both sides, the bottom of the catheter is fixedly installed with a discharge end, the outer surface of the catheter is provided with scales, and the outer surface of the catheter is provided with a limiting component. The limiting component includes a limiting sleeve, the limiting sleeve is slidably sleeved on the outer surface of the catheter, one end of the limiting sleeve facing the urine drainage hole is fixedly installed with a limiting plate, and a fixing bolt is screwed and assembled on the limiting sleeve, and one end of the fixing bolt abuts against the outer surface of the catheter.

[0008] Preferably, a section of the catheter connecting to the discharge end is made of PEBA material, and a section of the catheter with urine drainage holes is made of natural latex material.

[0009] Preferably, a switch valve is installed inside the discharge end.

[0010] Preferably, two connecting blocks are fixedly installed on the front surface of the elastic belt. One end of each connecting block is fixedly installed with a fixing ring, and bolts II are screwed and assembled on the fixing rings.

[0011] Preferably, connecting plates are fixedly installed on both sides of the limiting sleeve. Connecting guide rods are fixedly installed on the surfaces of the connecting plates, and one end of each connecting guide rod extends into the inside of the fixing ring.

[0012] Compared with the prior art, the present utility model provides an intermittent catheter with scales, having the following beneficial effects:

[0013] 1. When using the intermittent catheter with scales, after the patient wears the elastic belt, the catheter is inserted into the bladder through the urethra. During the insertion process, the insertion depth can be mastered according to the indication of the scales, avoiding being too deep or too shallow. The surface of the catheter is smooth, which can effectively reduce the harm to the patient's urethra during insertion.

[0014] 2. When the catheter is inserted to an appropriate position (i.e., the urine drainage holes are inside the bladder), the limiting sleeve is pushed to the patient's lower body by sliding, and then the fixing bolt is rotated to fix the limiting sleeve on the catheter. The limiting plate will play a blocking role to prevent the catheter from continuing to penetrate into the urethra and causing injury. Then, by inserting the connecting guide rod into the fixing ring and fixing it with bolt II, the catheter can be completely fixed on the patient to prevent the catheter from moving during the patient's activity and affecting the urine drainage work.

[0020] Please refer to Figures 1-4 , an intermittent urinary catheter with a scale, including a urinary catheter 1 and an elastic belt 3. The surface of the urinary catheter 1 is smooth, which can effectively reduce the harm to the patient's urethra during insertion. On both sides of the top end of the urinary catheter 1, urinary catheterization holes 12 are provided. At the bottom end of the urinary catheter 1, a discharge end 13 is fixedly installed. On the outer surface of the urinary catheter 1, a scale 11 is provided for observing the insertion depth of the urinary catheter 1. A limiting component is arranged on the outer surface of the urinary catheter 1, which can play a certain blocking role to prevent the urinary catheter 1 from continuing to penetrate deep into the urethra and causing damage. The limiting component includes a limit sleeve 2. The limit sleeve 2 is slidably sleeved on the outer surface of the urinary catheter 1. A limiting plate 23 is fixedly installed at one end of the limit sleeve 2 facing the urinary catheterization hole 12. A fixing bolt 21 is screwed and assembled on the limit sleeve 2. One end of the fixing bolt 21 abuts against the outer surface of the urinary catheter 1, and the fixing bolt 21 can fix the limit sleeve 2 on the urinary catheter 1.

[0021] Among them, a section of the urinary catheter 1 connecting the discharge end 13 is made of PEBA material. The PEBA material is relatively hard, which is convenient for the limit sleeve 2 to be fixed on it. A section of the urinary catheter 1 with urinary catheterization holes 12 is made of natural latex material. The natural latex material is soft, easy to be surface silicon-treated, has very little irritation, and has good biocompatibility, which can improve the comfort of the patient.

[0022] Among them, a switch valve is installed inside the discharge end 13 for controlling the opening and closing of the discharge end 13. When the urinary catheter 1 is inserted, it is closed to prevent urine leakage and affect the hygiene and tidiness of the patient. After the urinary catheter 1 is installed, the discharge end 13 is opened through the switch valve for urination.

[0023] Refer to Figure 3 , two connecting blocks are fixedly installed on the front surface of the elastic belt 3. At one end of each connecting block, a fixing ring 31 is fixedly installed. Second bolts 32 are screwed and assembled on the fixing rings 31. Connecting plates 22 are fixedly installed on both sides of the limit sleeve 2. Connecting guide rods 24 are fixedly installed on the surfaces of the connecting plates 22. One end of each connecting guide rod 24 extends into the inside of the fixing ring 31. By inserting the connecting guide rod 24 into the fixing ring 31 and fixing it with the second bolt 32, and cooperating with the limiting plate 23, the urinary catheter 1 can be completely fixed on the patient's body to prevent the urinary catheter 1 from moving when the patient moves and affecting the urinary catheterization work.

[0024] Working principle: For this graduated intermittent urinary catheter, when in use, after the patient wears the elastic belt 3, the urinary catheter 1 is inserted into the bladder through the urethra. During the insertion process, the insertion depth can be controlled according to the indication of the scale 11 to avoid being too deep or too shallow. When the urinary catheter 1 is inserted into the appropriate position (i.e., the urine drainage hole 12 is inside the bladder), it is pushed to the patient's lower body by sliding the limit sleeve 2, and then the fixing bolt 21 is rotated to fix the limit sleeve 2 on the urinary catheter 1. The limit plate 23 will play a blocking role to prevent the urinary catheter 1 from continuing to penetrate into the urethra and causing damage. Then, by inserting the connecting rod 24 into the fixing ring 31 and fixing it with bolt two 32, the urinary catheter 1 can be completely fixed on the patient to prevent the urinary catheter 1 from moving during the patient's activities and affecting the urine drainage work;

[0025] After the urinary catheter 1 is installed, the switch valve inside the discharge end 13 is opened, and the urine in the bladder will enter the urinary catheter 1 through the urine drainage hole 12 and flow out of the body along the pipeline. After the urine drainage is completed, the switch valve of the discharge end 13 is closed, and the urinary catheter 1 is gently pulled out;

[0026] Note that during the pulling out process, the movement should be kept gentle to avoid irritating or damaging the urethra. The used urinary catheter 1 and elastic belt 3 should be cleaned and disinfected in time for the next use. At the same time, pay attention to checking whether the urinary catheter 1 has any damage or aging phenomenon, and if necessary, replace it with a new urinary catheter in time.
