Description

Technical Field

[0001] The present invention relates to a urinary catheter, specifically a portable urinary catheter. Background Art

[0002] A urinary catheter is a tube inserted into the bladder through the urethra for urine drainage. It is a tube made of natural rubber, silicone rubber or polyvinyl chloride (PVC). It can be inserted into the bladder through the urethra to drain urine. After the urinary catheter is inserted into the bladder, there is an airbag near the head end of the urinary catheter to fix the urinary catheter in the bladder and prevent it from slipping out easily. The drainage tube is connected to a urine bag to collect urine. For patients with involuntary urination or urinary incontinence, in order to prevent urine from flowing out of the body and wetting clothes and other items, a urinary catheter is usually used to drain urine out of the body. However, large urinary catheterization devices are not convenient to carry, and it is inconvenient for patients to go out for examinations or receive home care. Moreover, most of the urine drainage ports on the existing urinary catheters are located above the airbag. When the airbag is filled, its volume increases, and the urinary catheter can only drain the urine above the airbag. If the patient needs to completely drain the urine in the bladder, the operation is difficult. Summary of the Invention

[0003] The purpose of the present invention is to provide a portable urinary catheter. Insert a disinfected guide core into the outer tube, so that the guide core body blocks the communication between the through hole and the mating hole. Insert the outer tube into the urethra, and judge the insertion depth through the scale line. After the airbag enters the bladder, open the switch of the regulating valve on the second control member, add distilled water into the control tube of the second control member, and the distilled water enters the airbag to make the airbag filled and positioned to prevent the urinary catheter from slipping out. Close the second control member and open the first control member. The urine in the bladder and above the airbag enters the liquid guide hole and flows out of the body through the liquid guide channel. When the patient needs to completely drain the urine in the bladder, pull the guide core outwards to make the through hole communicate with the mating hole, and the urine enters the through hole from the liquid guide groove and then flows out of the body. The urinary catheter can drain urine according to different conditions of patients, has a wide range of applications, is simple in structure, convenient for patients to carry, the control member regulates urine drainage, is convenient for patients to replace the urine bag, the scale line helps to judge the insertion depth, prevents the airbag from causing harm to the urethra, and the operation is simple and convenient.

[0012] Advantages of the present invention:

[0013] 1. The urinary catheter of the present invention can control the communication between the through hole and the mating hole through the guide core according to different conditions of patients, gradually drain urine, has a wide range of applications, and the control member regulates urine drainage, which is convenient for patients to replace the urine bag. The urinary catheter has a simple structure, is convenient for patients to carry, and is suitable for practical use;

[0014] 2. The operation of the urinary catheter of the present invention is simple. Insert the disinfected guide core into the outer tube to block the communication between the through hole and the mating hole by the guide core body. Insert the outer tube into the urethra, and judge the insertion depth through the scale line. After the airbag enters the bladder, open the switch of the regulating valve on the second control member, add distilled water into the control tube of the second control member, and the distilled water enters the airbag to make the airbag full and positioned to prevent the urinary catheter from slipping out. Close the second control member and open the first control member. The urine in the bladder and above the airbag enters the liquid guiding hole and flows out of the body through the liquid guiding channel. When the patient needs to drain all the urine in the bladder, pull the guide core outwards to make the through hole communicate with the mating hole, and the urine enters the through hole from the liquid guiding groove and then flows out of the body. The scale line helps to judge the insertion depth and prevent the airbag from damaging the urethra. BRIEF DESCRIPTION OF THE DRAWINGS
