Wherein, after the pressure measuring valve was opened, in the normal saline in the patient's bladder got into the closed container through the feed liquor pipe under the effect of bladder pressure, pressed the gas in the closed container and in the pipeline to the manometer to detect gaseous pressure by the manometer and obtain patient's bladder pressure. Because the manometer only with the airtight container in the gas contact, consequently the utility model discloses can directly adopt mechanical or electronic type pressure gauge to measure and need not rinse the pressure gauge, avoid measuring liquid to spill and ensure measuring result's accuracy then.
In order to prevent the liquid in the closed container from flowing back to the catheter, a one-way valve is connected between the pressure measuring valve and the liquid inlet pipe.
In order to further prevent the pressure gauge from being polluted, the closed container is filled with sterilization liquid, and the liquid level of the sterilization liquid is higher than that of the liquid outlet of the liquid inlet pipe.
In order to facilitate the discharge of liquid in the closed container, the closed container is a cone-bottom container, and the bottom of the closed container is connected with a liquid discharge valve.
Preferably, the pressure gauge is detachably connected with the pressure measuring interface so as to conveniently release pressure of the sealed container.
Particularly, the pressure measuring interface is inserted with a pagoda-shaped joint so as to be convenient for realizing the connection and the disassembly of the pressure measuring meter and the pressure measuring interface.
In order to facilitate reading of the pressure gauge, the pressure gauge is a digital hand-held pressure gauge.
The utility model has the advantages that:
use the utility model discloses when measuring patient's bladder pressure, the manometer only with the airtight container in the gas contact, can directly adopt mechanical or electronic type's pressure gauge to measure and need not wash the pressure gauge, avoid measuring liquid to spill then and ensure measuring result's accuracy.
