Description

Technical Field

[0001] The invention belongs to the technical field of bladder flushing, and specifically refers to a bladder flushing device for urology nursing. Background Art

[0002] After urinary system diseases or surgery, blood, pus, mucus, necrotic tissue and other substances may accumulate in the bladder, which may block the catheter and affect the normal drainage of urine. Through bladder irrigation, the flow of the flushing fluid can flush these blockages out of the body, ensure the patency of the catheter, enable urine to be discharged smoothly from the bladder, prevent excessive pressure in the bladder, and avoid damage to kidney function.

[0003] In the process of bladder irrigation, the existing technology adopts a method of inserting the insertion end of the catheter into the bladder in the patient's body, and the rear end of the catheter is bifurcated into two catheters, namely an injection tube and a drainage tube. When in use, the drainage tube is first closed, and the irrigation liquid is transported to the insertion end through the injection tube to irrigate the bladder, and then the injection tube is closed and the drainage tube is opened, and the liquid in the bladder is introduced from the insertion end into the drainage tube for discharge, that is, the injection and drainage are interconnected, which is prone to catheter contamination.

[0004] During cleaning and drainage, the catheter is inserted into the patient's body. Currently, the catheter is fixed only by adhesive tape, which is not strong enough and is prone to deviation and tilt, causing discomfort to the patient or affecting the normal cleaning and drainage process.

[0005] During the drainage process, some blood clots, component lumps and other solid objects may be discharged. Since the catheter is thin, it is easy to cause blockage, which in turn affects normal drainage. Summary of the invention

[0006] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a bladder flushing device for urological surgery care, which solves the problems of inconvenient use of catheters in the prior art and easy contamination and interference between catheters, improves the stability of drainage, and maintains smooth drainage.

[0007] The technical solution adopted by the present invention is as follows: The present invention provides a bladder flushing device for urology nursing, comprising:

[0008] Flushing and drainage equipment, with flushing and drainage functions;

[0009] A catheter is connected to the flushing and drainage device, and one end of which is inserted into the patient's body to inject flushing fluid into the patient's bladder and drain the flushing fluid;

[0010] A positioning mechanism is disposed on the patient's body and connected to the catheter to control the fixation of the catheter;

[0011] The filtering and anti-clogging mechanism is connected to the catheter and is used to filter the drainage fluid to prevent the obstruction from clogging the catheter and affecting the drainage;

[0012] One end of the catheter is a collection end, and the other end is a bifurcated end. A flushing pipeline and a drainage pipeline are arranged in the collection end, and the flushing pipeline and the drainage pipeline are not connected. The bifurcated end is provided with a bifurcated flushing tube and a bifurcated drainage tube, and the bifurcated flushing tube is connected to the flushing pipeline, and the bifurcated drainage tube is connected to the drainage pipeline;

[0013] The above structure integrates the front ends of two independent and unconnected catheters into one, thereby facilitating the insertion of the structural catheter into the patient's body. During the flushing process, the flushing fluid enters the bladder through the bifurcated flushing tube, and after flushing, it enters the bifurcated drainage tube from the bladder and is discharged. During the whole process, the body fluids in the two tubes are not connected to each other, so no contamination will be caused.

[0020] Furthermore, the filter inlet is close to the high end of the filter screen.

[0021] When the drainage liquid enters the filter box, it is filtered through the filter net. When deposits are generated on the filter net, the filter dragon is controlled to rotate to transport the blockages to the storage box, thereby maintaining the filtering effect of the filter net.

[0022] Furthermore, a flow rate sensor is provided on the bifurcated drainage tube connected to the filter outlet. When a decrease in flow is detected, a blockage occurs on the surface.
