Problems solved by technology

The above-mentioned prior art uses drainage negative pressure balls to form negative pressure unstable, and the large amount of urine requires repeated operations to create negative pressure, which increases the workload of medical staff, and is unable to perceive changes in the amount of urine in the bladder, and cannot promptly drain the urine. drain

Embodiment 1

[0056] refer to Figure 10 , a urinary catheterization method in urology, comprising the following steps:

[0057] S1, connect one end of the catheter to the non-return device of the negative pressure tank, and guide or leave the other end of the catheter in the bladder;

[0058] S2, if there is a central negative pressure system, close the valve of the ventilation box, connect the central negative pressure system through a universal joint to form a negative pressure on the negative pressure tank, the urine enters the negative pressure tank through the catheter and the non-return mechanism, and passes through drain outlet;

[0059] S3, if there is no central negative pressure system, close the valve of the universal joint, connect the negative pressure mechanism through the Y-shaped tube, and monitor the pressure value inside the bladder through the set pressure sensing probe. When the pressure value inside the bladder is greater than the set value, The controller sends an i...

Embodiment 2

[0064] Please refer to Figure 1-3 , a catheterization system for urology, comprising a negative pressure tank 1; a catheter 2 is connected above the negative pressure tank 1, and a non-return mechanism is provided at one end of the catheter 2 connected to the negative pressure tank 1 6. The bottom of the negative pressure tank 1 is provided with a liquid discharge port 8, and the inside of the negative pressure tank 1 is a negative pressure chamber 7. There is a box body 3 on one side of the negative pressure tank 1, and the inside of the box body 3 is close to the top position A negative pressure tube 9 is provided, one side of the negative pressure tube 9 communicates with the negative pressure tank 1, the other end of the negative pressure tube 9 extends to the outside of the box body 3, and the negative pressure tube 9 is connected with a universal joint 12 , connected to the central negative pressure system through a universal joint 12, the universal joint 12 is provided...

Embodiment 3

[0074] Please refer to Figure 4-6 , on the basis of Embodiment 1, the check valve includes a tube body 61, one end of the tube body 61 communicates with the urinary catheter 2, a sealing body 62 is provided inside the tube body 61, and a communication channel is formed by the sealing body 62. hole 63, one side of the through hole 63 is matched with a stopper 64, and the stopper 64 is sealingly connected with the sealing body 62; one side of the stopper 64 is connected with a second spring 65, and the second spring The other end of 65 is connected with a baffle 66, and the baffle 66 is connected with the inner wall of the pipe body 61; the inner wall of the pipe body 61 is provided with a channel 67 near the baffle 66, through which the two sides of the baffle 66 are communicated.

[0075] The end of the tube body 61 away from the sealing body 62 is provided with a liquid guide port 68, the liquid guide port 68 is formed by bonding a first sheet 681 and a second sheet 682, and...

Abstract

The urinary catheterization method comprises the following steps that S1, one end of a catheter is connected with a non-return device of a negative pressure tank, and the other end of the catheter is guided into or left in the bladder; s2, if the central negative pressure system exists, the universal joint is connected with the central negative pressure system to form negative pressure on the negative pressure tank; s3, if no central negative pressure system exists, a negative pressure mechanism is connected through a Y-shaped pipe, the pressure value in the bladder is monitored through an arranged pressure sensing probe, and when the pressure value in the bladder is larger than a set value, a controller sends out an instruction for opening a valve connected with a ventilation box, and meanwhile the controller starts a double-shaft motor to drive the negative pressure mechanism to work; the urine volume monitoring system is arranged to be matched with the negative pressure mechanism, urine catheterization is automatically carried out, the urine monitoring accuracy is improved, and operation is easy and convenient.

Description

technical field [0001] The invention belongs to the technical field of urinary catheterization, in particular to a urinary catheterization method in urology. Background technique [0002] Catheterization is the insertion of a catheter through the urethra into the bladder to drain urine. The purpose is to relieve urinary retention, take uncontaminated urine samples for examination, measure residual urine, measure bladder cold and heat sensation, volume, pressure, inject contrast medium or drugs to help diagnosis or treatment, etc. [0003] The current catheterization device generally uses a common drainage bottle, which is passed into the bladder through a catheter or an indwelling tube, and the urine automatically flows into the catheter bag through a natural drainage method. Since the urine is diverted at all times, it is not convenient for the patient's movement and perception and control of urine volume. It is necessary to always pay attention to the fluid storage volume...
