The invention provides a medical negative pressure drainage device which comprises a main body, a first channel, a second channel, a supporting plate, a pressing head and a floating negative pressure indicator, wherein a vertical scale mark and an oblique scale mark are respectively formed in the outer part of the main body and are used for observing the amount of liquid in the main body; the oblique scale mark is positioned at the bottom position of the main body; the main body comprises an upper part and a lower part; the upper part and the lower part are welded in a sealed mode; the first channel is formed inside the supporting plate and the pressing head; the second channel is formed inside the pressing head and is communicated with the first channel; the lower end of the second channel is strip-shaped and is positioned above the tip of the pressing head; the tip is triangular; the floating negative pressure indicator is fixedly matched with the supporting plate, is arranged on one side of the main body and is used for displaying the pressure condition inside the main body. The negative pressure drainage device disclosed by the invention is simple in structure, convenient to operate and high in sealing property and can control the flow; the floating negative pressure indicator is used for displaying the pressure condition inside the main body; and medicines can be added through a dosing opening.
Description
technical field [0001] The invention relates to the technical field of medical instruments, in particular to a negative pressure drainage device. Background technique [0002] Negative pressure bottles are widely used in medical treatment for negative pressure drainage. However, most of the existing negative pressure bottles are inconvenient to operate, the flow rate cannot be adjusted manually, and the structure is poorly sealed and the warranty period is short. Contents of the invention [0003] (1) Technical problems to be solved [0004] The problem to be solved by the present invention is to provide a negative pressure drainage device to overcome the defects in the prior art that the negative pressure bottle is inconvenient to operate, the flow cannot be manually adjusted, the structure is poor in sealing, and the warranty period is short. [0005] (2) Technical solution [0006] In order to solve the above technical problem, the present invention provides a negativ...
