Embodiment Construction

[0021] Below, the present invention will be further described in detail in conjunction with the accompanying drawings and embodiments.

[0022] A disposable medical negative pressure gas connector anti-backflow device of the present invention, such as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Figure 6 As shown, it has a structure, an anti-backflow device that can close the suction nozzle in time to prevent the liquid in the liquid collection bottle 9 from entering and the negative pressure gas backflow is added between the negative pressure gas joint 4 and the liquid collection bottle 9 6. The cooperation relationship between the anti-backflow device 6 and the negative pressure gas connector 4 and the liquid collection bottle 9 is realized through the connection and combination of the quick plug 5 and the connecting pipe 7 .

[0023] Its structure is: it includes a negative pressure gas connector 4, a liquid collection bottle 9, and also includes a backfl...

Abstract

The invention discloses a disposal medical negative pressure gas joint backflow prevention device which comprises a negative pressure gas joint (4), a liquid collecting bottle (9) and a backflow prevention device (6), wherein the outlet end and the inlet end of the backflow prevention device are respectively connected and conducted with the negative pressure gas joint and the liquid collecting bottle; the backflow prevention device further comprises a hollow integrated outer casing (1) with an inlet joint integrated structure, an outlet joint (3) with an opened inlet end part inner cavity concave platform structure and a sealing filter element (2) for embedding and connecting the inlet end part notch of the outlet joint and sealing pores; and the sealing filter element is a honeycomb pinhole structure with a built-in center concave hole structure, and the shape of the center concave hole is matched with that of the filter element body. The disposal medical negative pressure gas joint backflow prevention device disclosed by the invention has the characteristics of simple structure, convenience for assembly, capability of quickly sealing and blocking and the like, and can satisfy the requirements of backflow prevention control of the negative pressure gas joint.

Description

technical field [0001] The invention relates to an auxiliary device for clinical medical care, in particular to a disposable medical negative pressure gas joint anti-backflow device capable of preventing gas backflow and waste liquid from entering. Background technique [0002] In the prior art, the suction terminals used in hospital operating rooms and wards can easily enter the terminals and pipelines during the monitoring and suction process, and the waste liquid in the collection bottles (bags) will easily enter the terminals and pipelines, resulting in blockage of the suction terminals and pipelines, affecting the Bleeding, dirt and debris are attracted during patient monitoring or surgery, and bacterial cross-infection is prone to occur. The internal parts of the suction terminal are rusted, resulting in a decrease in negative pressure suction pressure and short service life. Frequent maintenance and cleaning or replacement of parts are required. Increased maintenance ...
