Embodiment Construction

[0017] As shown in the figure, Pascal’s disposable external urinary catheter includes a urine chamber 6, which is fixed on a base plate 8, and a vertical cylinder 4 is fixed in the middle of the urine chamber 6, and the inner diameter of the cylinder 4 is larger and lower. Small, the inner diameter of the upper section of the cylinder 4 matches the diameter of the piston 2, the inner diameter of the lower section of the cylinder 4 matches the diameter of the built-in ultra-fine diversion microneedle nozzle 3, and the piston 2 and the built-in type are arranged in the cylinder 4 The ultra-fine diversion microneedle nozzle 3 is provided with a high-pressure gas inlet nozzle 1 on the upper end of the cylinder 4, and a negative pressure nozzle 12 connected with the urine chamber 6 is provided on the side wall of the urine chamber 6. There is a urination hole 4 communicated with the urine storehouse 6 on the upper cavity wall.

Abstract

The utility model discloses a Pascal disposable in-vitro urethral catheterization device. The device comprises a urine bin; the urine bin is fixed on a base plate; a vertical cylinder barrel is fixedin the middle of the urine bin; the inner diameter of the cylinder barrel is smaller from top to bottom; the inner diameter of the upper section of the cylinder barrel fits the diameter of a piston; the inner diameter of the lower section of the cylinder barrel fits the diameter of a built-in superfine flow guide micro-needle nozzle; the piston and the built-in superfine flow guide micro-needle nozzle are arranged in the cylinder barrel; a high-pressure air inlet nozzle is arranged at the upper end of the cylinder barrel; a negative-pressure air nozzle communicating with the urine bin is arranged on the side wall of the urine bin; and a urination hole communicating with the urine bin is formed in the upper-section cavity wall of the cylinder barrel. Compared with the prior art, the in-vitro urethral catheterization bin is separated from a human body, causes no pain to a patient, and is convenient to operate.

Description

technical field [0001] The invention relates to a urinary catheter, in particular to a Pascal disposable external urinary catheter. Background technique [0002] As we all know, in medicine, a catheter is inserted through the urethra to the bladder to drain urine. Catheterization is divided into two types: indwelling catheterization and intermittent catheterization. The former urinary catheter remains in the patient's body all the time, and it is pulled out or replaced with a new tube regularly when the condition permits. The latter catheterizes every 4-6 hours, and the catheter is pulled out after the bladder is emptied. Whether it is indwelling catheterization or intermittent catheterization, the patient not only has to bear the pain of catheterization from the urethra to the bladder, but also has the risk of infection. Therefore, designing a Pascal disposable external urinary catheter is a technical problem to be solved at present. Contents of the invention [0003]...
