Improved negative-pressure aspirator

Abstract

An improved negative-pressure aspirator comprises a liquid storage bottle, a catheter and a negative-pressure machine. The liquid storage bottle is provided with a bottle plug and is connected with the negative-pressure machine through the catheter on the bottle plug, the lower end of the liquid storage bottle is provided with a liquid discharging pipe, the end, close to the liquid storage bottle, of the liquid discharging pipe is provided with a left-right push-type switch, the bottle plug is further provided with a cleaning pipe and a sucking pipe, the sealed end of the cleaning pipe penetrates through the bottle plug and is arranged in the liquid storage bottle, cleaning holes are distributed in the pipe wall of the sealed end of the cleaning pipe, a cleaning valve is arranged at the other end of the cleaning pipe, a suction port of the sucking pipe is formed at the end, connected with a stomach pipe, of the sucking pipe, and the sucking pipe is provided with a sucking valve. The bottom of the liquid storage bottle of the negative-pressure aspirator is provided with the liquid discharging pipe, the stomach pipe does not need to be frequently pulled open, gastric juice can be poured in a daily drainage mode, the pollution possibility is reduced, work is facilitated, the bottle plug of the liquid storage bottle is provided with the cleaning pipe, cleaning work can be carried out without the need of taking down the liquid storage bottle from the negative-pressure machine, and the work load of nurses is greatly reduced.

Description

technical field [0001] The invention belongs to the field of medical equipment, and mainly relates to an improved negative pressure suction device. Background technique [0002] The pouring port of the negative pressure suction device used in clinical practice is on the top. When draining liquid, it is necessary to pull out the gastric tube, clamp the gastric tube, remove the negative pressure suction device from the gastric tube, pour it out from the pouring port, and open the gastric tube interface frequently , easy to pollute, and cause inconvenient work; and the opening is on the top, and the gastric juice is not fully poured. At the same time, the liquid storage bottle of the used suction device needs to be cleaned in time, and it is very inconvenient to get in and out of the cleaning liquid during cleaning, and the workload is very heavy. Contents of the invention [0003] In order to overcome the above disadvantages, the present invention provides an improved negat...
