Intelligent medical negative pressure drainage device convenient to use

Abstract

A disclosed intelligent medical negative pressure drainage device convenient to use comprises a first liquid storage tank, a plurality of connecting air pipes and a communicating pipe, a second liquid storage tank is arranged on one side of the first liquid storage tank, and threaded connectors are fixedly connected to the top of the first liquid storage tank and the top of the second liquid storage tank; and the tops of the threaded connectors are movably connected with anti-backflow connectors, a negative pressure generating device is arranged on one side of the first liquid storage tank, the first liquid storage tank communicates with the interior of the second liquid storage tank through an arranged communicating pipe, and a multi-way electromagnetic valve is arranged on the outer side of the first liquid storage tank. The negative pressure generating device works to generate negative pressure, liquid is sucked into the first liquid storage tank through a liquid suction pipe, after the first liquid storage tank is full of the liquid, the liquid enters the anti-backflow connector along the threaded connector, the structure in the anti-backflow connector is triggered after being filled with water, and through signal transmission, a passage between the first liquid storage tank and the negative pressure generating device is controlled to be closed so as to prevent liquid from entering.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, and in particular relates to an intelligent and easy-to-use medical negative pressure drainage device. Background technique [0002] Under normal conditions, there is a small amount of fluid in the thoracic cavity and abdominal cavity of the human body, which can lubricate the organs in the cavity. If the amount of fluid in the cavity increases beyond the normal physiological range under pathological conditions, it will become a disease, such as pleural pleural effusion. fluid and ascites, surgical drainage is aimed at fluids accumulated in body cavities, joints or tissues, including infectious fluids and non-infectious fluids, through drainage can reduce pressure, relieve pain, reduce the possibility of infection, and is conducive to wound healing heal. The negative pressure drainage device is a device that can fully drain the effusion. Through its own negative pressure system, it can...

Problems solved by technology

[0004] The purpose of the present invention is to provide an intelligent and easy-to-use medical negative pressure drainage device, so as to solve the problem that during the use of the existing medical negative pressure drainage device proposed in the above-mentioned background technology, after the liquid inside the bottle is filled, It will directly enter the interior of the negative pressure generating device along the pipeline, causing damage to the device. This requires medical personnel to always pay attention to the situation in the bottle, and it is easy to be distracted during the operation. There are many inconveniences in the operation of changing the bottle manually
