Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a bladder irrigation device. Background Technology

[0002] Bladder tamponade is a common emergency in urology, which refers to a large amount of bleeding from the urinary system in a short period of time caused by various etiologies. The blood coagulates and accumulates in the bladder, leading to a series of symptoms such as hemorrhagic shock, urinary retention, and bladder spasm.

[0003] Currently, the clinical treatment for bladder tamponade usually involves manual bladder irrigation via a urinary catheter. In emergencies, hemostatic drugs can be instilled into the bladder.

[0004] However, manual bladder irrigation has drawbacks such as the irrigation process being invisible, pressure being uncontrollable, lack of standardized operating techniques, and difficulty in assessing the irrigation effect, which affect the clinical treatment outcome. Utility Model Content

Next, the probe of the endoscope mechanism is withdrawn, and the negative pressure suction catheter is inserted into the bladder irrigation catheter, forming an irrigation water channel between the outer wall of the negative pressure suction catheter and the inner wall of the bladder irrigation catheter. Irrigation water is then introduced into the irrigation water channel through the irrigation water inlet on the rear side wall of the bladder irrigation catheter, allowing the irrigation water to be sprayed into the bladder to be treated from the front end of the irrigation water channel for irrigation. Simultaneously, the inlet of the negative pressure suction mechanism is connected to the rear end of the negative pressure suction catheter, allowing drainage of the bladder to be treated through the negative pressure suction mechanism. When bladder irrigation is complete, the negative pressure suction catheter is withdrawn, and the endoscope mechanism is reinserted to observe the bladder irrigation effect and changes in the blood clot.

In this embodiment, the negative pressure suction mechanism is preferably a negative pressure suction device. The probe of the endoscope mechanism can be inserted into the bladder irrigation catheter 1 to take pictures inside the bladder to be treated. In this embodiment, the endoscope mechanism is preferably a cystoscope.

[0031] In this embodiment, both the bladder irrigation catheter 1 and the negative pressure suction catheter 2 are flexible tubes; specifically, the bladder irrigation catheter 1 in this embodiment has a diameter of 18Fr-24Fr and is flexible and bendable, providing support for the urethra to establish a channel. Figure 1 The dotted line indicates the bent state of the bladder irrigation catheter 1 (with the tip bent to both sides), which facilitates bladder irrigation and other functions.
