Description

Technical Field

[0001] The present invention relates to the technical field of urology medical equipment, in particular to a urology catheterization device and a use method thereof. Background Art

[0002] A urological catheterization device is a medical tool used to guide the discharge of urine. It is usually made of soft material and can be safely inserted into the urethra to drain urine from the bladder to the outside of the body. After the catheter is inserted into the bladder, it is inflated and fixed by an air bag to achieve the purpose of indwelling the catheter. At the same time, it is connected to a urine bag to collect urine.

[0003] The patent with application number CN201810869407.6 discloses a urinary catheter, including a catheter and an expansion guide. A urinary catheter hole is provided at one end of the catheter, and the catheter is sleeved on the outside of the expansion guide. The expansion guide includes an introducer body, an expansion body, an introducer seat and a sliding sleeve. The introducer body includes a guide part, an expansion body and a main body in sequence. The sliding sleeve is slidably sleeved on the main body. The main body is connected to the introducer seat at one end away from the expansion body. The expansion body includes no less than 4 elastic frames, and elastic frame connectors are respectively provided at both ends of the elastic frame. The elastic frame is arranged at the expansion body through the elastic frame connector. The length of the main body is not less than the length of the catheter. The above technical scheme provides a new way for the insertion of the urinary catheter, with small insertion resistance and less pain for the patient.

[0004] However, existing catheters may lack effective antibacterial design, resulting in external bacteria easily attaching to the outside of the catheter during insertion into the urethra, and then entering the patient's urethra along with the catheter, increasing the risk of infection. In addition, existing catheters may lack a stable fixing device at the connection between the outer sleeve and the liquid inlet tube of the urine bag, resulting in the connection easily loosening or falling off during catheterization, increasing the risk of urine leakage.

8. The urological catheterization device according to claim 7, characterized in that: The clamping device (300) further comprises a connecting plate (330) bonded and fixed to the inner side wall of the outer casing frame (310), an outer convex rod (340) clamped and fixed to the outer side wall of the connecting plate (330), and a second pressure spring (350) sleeved on the outer side wall of the outer convex rod (340).

9. The urological catheterization device according to claim 8, characterized in that: The upper and lower square plates of the movable frame (361) are slidably connected to the inside of the frame surface slot (311); the outer side walls of the upper and lower square plates of the movable frame (361) are provided with guide slots (3610) that pass through from top to bottom; an extension rod (362) is clamped between the movable frame (361) and the limit clamp (363); the elastic force provided by the second pressure spring (350) pushes the movable frame (361) to move in the direction of the limit clamp (363); and the limit clamp (363) is slidably connected to the outer side wall of the hard rubber tube (130).

10. A method for using a urological catheterization device, using the urological catheterization device according to any one of claims 1 to 9, characterized in that: The following steps are involved: S1. First, the end of the male patient's genitals is disinfected and then placed above the lower shell (211) in the antibacterial device (200); S2. Next, an external air pump is used to inflate the air inlet valve (2240) of the annular air bag (224), and the male patient's genitals are fixed inside the antibacterial device (200) through the annular air bag (224); S3. Subsequently, the medical staff observes the interior of the antibacterial device (200) through the observation glass (223), inserts the insertion tube body (110) into the patient's urethra, and then continues to extend the insertion tube body (110) inward until the expansion balloon (160) is inserted into the patient's bladder and stops, and then uses the external air pump to send airflow from the air inlet pipe (150) into the expansion balloon (160) again, so that the balloon expands in the patient's bladder; S4. During this process, the sealing film (120) moves along with the insertion tube (110), and the movable sleeve (171) cooperates with the film cutting sheet (172) to separate the sealing film (120) from the insertion tube (110); S6. After that, the medical staff inserts the liquid inlet tube of the urine bag into the interior of the outer sleeve (140), and then twists the film removal portion (170) as a whole, so that the tube wall protrusion (173) can be separated from the antibacterial device (200) as a whole through the limiting ring groove (2210); S7, then, the film removal part (170) is integrally inserted into the outer side of the hard rubber tube (130), and while the sealing film (120) is completely cut, the limiting clamping block (363) in the moving part (360) of the clamping device (300) is driven to move outside the hard rubber tube (130); S8, after the limiting clamping block (363) is displaced, the limiting clamping block (363) is driven by the extension rod (362) to move inside the frame surface slot (311), so that the contact position between the outer circular protrusion of the clamping block (320) and the guide slot (3610) is changed, thereby driving the clamping block (320) to move toward the outer sleeve (140), thereby fixing the outer sleeve (140) and the end of the liquid inlet tube of the urine bag; S9. Afterwards, the rotating lever (212) is moved to move the blocking rod (213) out of the air outlet pipe (2241). After the annular airbag (224) is reduced in size, the lower shell (211) is separated from the upper shell (221), thereby ensuring the subsequent comfort of the patient's reproductive organs.
