Pressure switching device and bladder irrigation device adopting same

Abstract

The invention discloses a pressure switching device and a bladder irrigation device adopting the pressure switching device. The pressure switching device comprises a reversing mechanism, a first connecting pipe, a pumping pressure mechanism, a second connecting pipe, a direct flow pipe and a tee joint, the water inlet end of the first connecting pipe and the water inlet end of the direct flow pipe are both communicated with the reversing mechanism, and the water outlet end of the first connecting pipe is communicated with the pumping pressure mechanism; the water outlet end of the first connecting pipe is communicated with the water inlet end of the pumping mechanism, and the water outlet end of the pumping mechanism is communicated with the water inlet end of the second connecting pipe; according to the pressure switching device, by arranging the reversing mechanism, the pump pressure mechanism, the first connecting pipe, the second connecting pipe, the tee joint and the like and adjusting the relative position of the movable rod and the sleeve shell, the water outlet end of the water inlet connector is aligned with different water inlets of the Y-shaped flow channel, and therefore flushing fluid can enter an infusion pipe through the pump pressure mechanism or a direct flow pipe, and flushing pressure switching is achieved; the flushing speed and pressure can be adjusted and controlled according to different requirements of patients.

Description

technical field [0001] The invention belongs to the technical field of bladder irrigation, and in particular relates to a pressure switching device and a bladder irrigation device using the pressure switching device. Background technique [0002] The bladder is an important organ of the human body. When it develops pathological changes or its function declines, it is generally treated with drugs by flushing. The commonly used method is: use a bladder flusher or a large syringe. The joints of the ostomy tube are separated, the distal drainage tube joint is wrapped with sterile gauze and put aside, the end of the urinary catheter or cystostomy catheter is sterilized and held with sterile gauze, and the irrigator with the flushing fluid is connected to the catheter At the end, slowly inject the irrigating fluid, then flow out naturally or slowly suck it out, and repeat this until the effluent is clear. After the rinsing is completed, rinse the distal drainage tube once, and the...

Problems solved by technology

This method is complicated to operate, and the injection port of the large syringe is in frequent contact with the discharge port of the flushing liquid, which is likely to pollute the flushing liquid and cause damage to the bladder. Therefore, in the later stage, the infusion bottle plug, air intake pipe, catheter, etc. are used to cooperate.

[0003] However, the above scheme still flushes the bladder by the self-gravity of the flushing solution during use. When the urethra is blocked by congestion, it is necessary to manually squeeze the guide tube repeatedly, which is time-consuming and laborious, and cannot be adjusted according to the different needs of patients. There are corresponding limitations in adjusting and controlling the speed, so we propose a pressure switching device and a bladder irrigation device using the pressure switching device
