Problems solved by technology

However, in the process of the catheter entering the body, such as in the male urethra, there is a bend position, and when the catheter head or catheter passes through this bend, it cannot pass smoothly, causing pain and discomfort, which is harmful to catheterization. Device placement presents a hassle that conventional catheterization devices do not address

Embodiment 1

[0026] Embodiment 1, when the present invention is in use, the water pump 9 pressurizes and fills the control airbag 7 for the initial expansion, and realizes positioning and fitting in the catheter head 1, and the medical staff inserts the catheter head 1 and the catheter 2 into the urethra, And the initial position makes the bending direction after expansion adapt to the direction of the curve in the urethra. The medical staff can judge whether the catheter head 1 can reach the curve according to experience and resistance. Continue to pressurize and fill the water, and the uneven axial expansion length of the control airbag 7 leads to bending, so that the attached urinary catheter head 1 follows the bending, and then can pass through the curve smoothly. After passing, the liquid is discharged to make the control airbag 7 contract and recover. After the catheter head 1 reaches the designated position in the body, the syringe 5 is used to inflate the positioning air bag 3 to re...

Embodiment 2

[0027] Embodiment 2, by controlling the communication of the syringe 5 through the control tube 14, when the syringe 5 communicates with the inflation tube 6 through a docking hole 15, the positioning airbag 3 can be inflated to make it inflated and positioned; turn the control tube 14 to disconnect The syringe 5 communicates with the inflatable tube 6, and the control tube 14 and the connecting tube 4 are rotated and sealed, and the inflatable tube 6 communicates with the docking hole 15 in a sealed state, and then the other docking hole 15 is connected to the output port of the syringe 5 , then the inside of the urinary catheter 2 is connected with the syringe 5. At this time, it is convenient to carry out work such as pumping / exhausting, liquid, etc., and when the port of the control tube 14 is sealed with a sealing cap 16, the syringe 5 can be used to extract the urinary catheter 2 The liquid inside forms a negative pressure suction.

Abstract

The invention discloses a catheterization device for urological surgery, which relates to the technical field of urological surgery. It includes a catheter head and a catheter; the catheter head is sealed and connected to the upper end of the catheter; the outer upper part of the catheter is sleeved with a positioning air bag; the lower end of the catheter is connected to a connecting tube; the side of the connecting tube The side is connected with a syringe; the positioning airbag is connected with an inflatable tube; the end of the inflatable tube is sealed and connected with the output port of the syringe; the control airbag is arranged in the catheter head; the lower end of the control airbag is connected with a water guide; The output end of a water pump is connected; the water pump is installed in the water tank; the lower part of the water guide pipe is equipped with a drain valve; the side of the catheter head is uniformly opened with catheter holes; , the catheter head is wrapped outside the control airbag. The beneficial effect of the present invention is that the bending can be actively controlled at the bend of the urethra, the bend can be passed smoothly, and the pain is relieved.

Description

technical field [0001] The invention relates to the technical field of urology. Background technique [0002] When performing catheterization work on urological patients, the catheterization device is used to connect with the patient's body to achieve catheterization. However, in the process of the catheter entering the body, such as in the male urethra, there is a bend position, and when the catheter head or catheter passes through this bend, it cannot pass smoothly, causing pain and discomfort, which is harmful to catheterization. The placement of the device presents a hassle that is not addressed by conventional catheterization devices. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a urinary catheterization device for urological surgery aiming at the above technical deficiencies. Actively controlled bending can be performed at the urethral bend, passing through the bend smoothly and reducing pain. [0004...
