Blood collection vein pressing device

Abstract

The invention discloses a blood collection vein pressing device. The blood collection vein pressing device comprises a bondage body, an air pressure switch, an inflating pump, an air vent valve, a power supply and an elliptical grip body. The inflating pump is provided with an air storage tank, a strip-shaped airbag is arranged in the middle of the back of the bondage body, the airbag is communicated with the air storage tank through an air inlet tube, the air storage tank is provided with the air pressure switch, the air inlet tube is provided with an air inlet one-way valve, the airbag is communicated with the air vent valve, and nylon buckles are arranged at the two ends of the bondage body. A button switch is arranged on the outer surface of the grip body. When the air vent valve is shut off and the button switch is continuously pressed, the inflating pump works and inflates the airbag. When the air pressure switch detects that pressure of air in the air storage tank reaches a set value P, the air pressure switch acts, and the inflating pump stops working and does not inflate the airbag any longer. When the button switch is loosened, the inflating pump is powered off, the air vent valve is opened, and the airbag exhausts air to the outside. The blood collection vein pressing device is convenient to operate mechanically, low in labor intensity, capable of saving time and labor and high in work efficiency.

Description

technical field [0001] The invention relates to a venous blood pressure collection device, which belongs to the technical field of medical instruments. Background technique [0002] At present, blood pressure collection devices mainly use rubber tubes or flat rubber belts. Although the rubber tubes or flat rubber belts have a simple structure, they need to be manually tied by medical personnel, which is labor-intensive, time-consuming, and labor-intensive, and the work efficiency is low. Contents of the invention [0003] The invention provides a venous blood collection device with low labor intensity and high work efficiency. [0004] The technical solution of the present invention is: the first blood pressure collection device, including a binding belt main body, an air pressure switch, an air pump, an air release valve, a power supply, and an oval hand-held main body, and the air pump is provided with an air storage tank. There is a strip-shaped air bag in the middle o...
