A liquid discharging device

Abstract

A liquid discharging device comprises a body provided with a liquid inlet and a liquid outlet. A liquid flow channel connected between that liquid inlet port and the liquid outlet port is arranged inthe body. The body is provided with a first control device that opens the liquid inlet port after the liquid pressure exceeds the preset pressure on the liquid inlet, or the body is provided with thefirst control device that opens the liquid outlet automatically when the liquid pressure in the liquid flow channel exceeding the preset pressure and/or the liquid volume exceeds the preset volume and/or the liquid level exceeds the preset height. Or the liquid flow channel is divided into an upper liquid flow chamber and a lower liquid flow chamber by a interceptor provided with a intercepting port in the middle of the liquid flow channel, and the liquid inlet port communicates with the liquid outlet through the intercepting port. The body is provided with a first control device that opens the intercepting port by itself after the liquid pressure in the upper liquid flow chamber exceeds the preset pressure and/or the liquid volume exceeds the preset volume and/or the liquid level exceedsthe preset height. The device prevents liquid from being unreasonably discharged by means of a first control device that switches the liquid flow path and a second control device that assists in switching the liquid outlet and shut-off ports. The invention is used in medical devices, articles and the industrial field.

Description

technical field [0001] The invention relates to medical equipment, supplies and industrial fields, in particular to a liquid discharge device. Background technique [0002] In clinical care, patients with drainage and indwelling catheterization often need to regularly open the fluid flow channel between the bladder and the drainage device to avoid excessive fluid pressure in the bladder, which may affect bladder function or even cause bladder rupture. Drainage devices that store patients’ drainage fluid usually require nurses to check and record the amount of drainage fluid frequently and pour out the drainage fluid in time, so as to avoid overflowing or backflowing back to the human body after the drainage fluid is full, causing iatrogenic pollution. [0003] In patients with urinary retention with a large amount of urine retention, during catheterization treatment, if the urination speed is too fast and the urination volume is too much, especially when the urination volume...
