Apparatus for discharging solution from catheter with pressure difference

Abstract

The invention relates to a device leading out liquid from a liquid delivery tube through pressure difference, which belongs to the technical field of daily life. The device comprises a cylinder body (1), a pressure spray head (2) arranged on the top end of the cylinder body (1), wherein a liquid inlet (5) of the pressure spray head (2) is connected with the liquid delivery tube (3) extending into the tube body (1). The device is characterized in that the liquid delivery tube (3) extends into the bottom of the tube body (1); a Y-shaped hollow liquid inlet mechanism (4) is arranged between the pressure spray head (2) and the liquid delivery tube (3); the upper part of the liquid inlet mechanism (4) is provided with two pipelines, the lower part of the liquid inlet mechanism (4) is provided with a pipeline and the middle of the liquid inlet mechanism (4) is provided with three pipelines which are communicated; the pipelines on the upper part are upper liquid inlet pipeline (41) and a liquid outlet pipeline (42); the pipeline on the lower part is a lower liquid inlet pipe (43); the liquid outlet pipeline (42) is connected with the liquid inlet hole (5) of the pressure spray head (2) through a hose; and the lower liquid inlet pipeline (43) is connected with the liquid delivery pipeline (3). The device which leads out the liquid from the liquid delivery tube through the pressure difference can be normally used in all directions.

Description

technical field [0001] The invention relates to a liquid outlet device, in particular to a liquid outlet device for discharging liquid from a catheter through a pressure difference. Background technique [0002] In daily life, people often need to directly spray the liquid enclosed in the bottle or cylinder to the desired place through a liquid outlet device. For example, a sprayer, the advantage of a sprayer is that it can refine or atomize the liquid when it is sprayed, so that it can be sprayed evenly; for example, a fire extinguisher, the substance in the bottle of the fire extinguisher usually exists in the form of a liquid, and it needs to be sprayed evenly when used to achieve a large and comprehensive coverage. Overrides the function of rapid fire suppression. These devices all make the air pressure in the bottle greater than the pressure in the nozzle by the pressure nozzle on the device, because of the pressure difference, the liquid flows out along the catheter t...
