Description
Technical Field
The utility model relates to a urinary catheter, in particular to a disposable external urinary catheter.
Background
It is well known in medicine to insert a catheter into the bladder via the urethra and drain the urine. Catheterization is divided into catheter indwelling catheterization and intermittent catheterization. The former catheter is always left in the patient and is pulled out or replaced by a new one regularly when the patient is allowed. The latter is used for catheterization every 4-6 hours, and the catheter is pulled out after the bladder is emptied. Whether indwelling or intermittent, the patient is not only exposed to insertion of the catheter from the urethra into the bladder, but is also at risk of infection. Therefore, designing a disposable external urinary catheter is a technical problem to be solved at present.
Disclosure of Invention
The utility model aims to solve the technical problem of providing a Pascal disposable external urinary catheter.
The utility model provides a technical scheme of its technical problem:
the disposable external urethral catheterization device comprises a urine bin, wherein the urine bin is fixed on a base plate, a vertical cylinder barrel is fixed in the middle of the urine bin, the inner diameter of the cylinder barrel is large at the top and small at the bottom, the inner diameter of the upper section of the cylinder barrel is matched with the diameter of a piston, the inner diameter of the lower section of the cylinder barrel is matched with the diameter of an embedded superfine diversion micro-needle nozzle, the piston and the embedded superfine diversion 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 communicated with the urine bin is arranged on the side wall of the urine bin, and a urine discharge hole communicated with the urine.
As a preferred scheme of the utility model, an outer chamber surrounding belly paste sticky skin is arranged on the base plate.
As a preferred scheme of the utility model, an electromagnetic air valve I communicated with a high-pressure air source is arranged on the high-pressure air inlet nozzle; and an electromagnetic air valve II connected with the vacuum pump is arranged on the negative pressure air tap.
As an optimized proposal of the utility model, the bottom in the urine bin is provided with a urine guiding indicator lamp and a urine detecting contact.
As an optimized proposal of the utility model, a contact starting switch I, a contact starting switch II and a urine detection contact are arranged on the base plate.
As an optimized proposal of the utility model, the urine bin is a transparent material urine bin, and a negative pressure display bottle with display scales is arranged on the urine bin.
The utility model discloses a use method and principle:
firstly, the utility model is placed on the body of a patient, and the embedded superfine diversion micro-needle nozzle is positioned right above the bladder of the patient; then the negative pressure air nozzle is communicated with the vacuum equipment and the vacuum equipment is started to vacuumize the urine bin, the high pressure air inlet nozzle is communicated with a high pressure air source for a short time, at the moment, the piston moves downwards under the action of high pressure air and drives the embedded superfine diversion micro-needle nozzle to move downwards until the embedded superfine diversion micro-needle nozzle is introduced into the bladder of a patient, at the fourth moment, the high pressure air is cut off, because the patient is in a urine holding state, namely the urine in the bladder is in a positive pressure state, the urine enters the urine bin along the embedded superfine diversion micro-needle nozzle and through a urine discharge hole on the cylinder barrel, at the moment, the piston floats upwards to the urine discharge hole under the impact of the urine, and the positive pressure liquid can rapidly flow to the negative pressure cavity (space) along the channel in the closed space according to the principle of the fluid mechanics flow law (the Archimedes's law principle), the path is that the bladder rapidly guides the pressure of the urine to the negative pressure cavity outside through the superfine diversion micro-needle (the pressure In the urine bin body.
Compared with the prior art, the external urethral catheterization bin of the utility model is separated from the human body, which not only causes no pain to the patient, but also has convenient operation.
