(2) Negative pressure suction system: the suction device must be placed within the range of 2.54-5.08cm from the smoke source to effectively suck the smoke. If it exceeds this range, the effect will be halved
(4) Surgical smoke purification device: The current surgical smoke purification device mainly processes surgical smoke through filtration and adsorption. One use one cleaning and disinfection, there is a risk of cross infection

Embodiment 1

[0017] Such as figure 1 The shown disposable surgical smoke purifier comprises a closed box body 1 provided with an air inlet 2, an air outlet 9 and an air outlet 10, and the air inlet and the air outlet are respectively arranged on two mutually parallel opposite sides of the box body 1. On the surface; from the air inlet to the air outlet in the box 1, there are filter chamber 5, VOCs absorption chamber 6, oxidation chamber 7 and carbon dioxide absorption chamber 8; the oxidation chamber 7 is filled with iodine pentoxide, and the The carbon dioxide absorbing chamber 8 is filled with soda lime. Iodine pentoxide can fully oxidize carbon monoxide gas into carbon dioxide gas, and the carbon dioxide gas is then absorbed by soda lime.

[0018] The filter cavity 5 is equipped with several HEPA filters parallel to the plane where the air inlet is located, which can intercept large particles, bacteria and viruses with a diameter greater than 0.3 microns in the surgical smoke.

Abstract

The invention discloses a disposable surgical smoke purifier. The disposable surgical smoke purifier comprises a closed box body which is provided with an air inlet and an air outlet, and the air inlet and the air outlet are formed in two surfaces, parallel and opposite to each other, of the box body; the box body is internally provided with a filter cavity, a VOCs absorption cavity, an oxidation cavity and a carbon dioxide absorption cavity from the air inlet to the air outlet in sequence; the oxidation cavity is filled with iodine pentoxide, and the carbon dioxide absorption cavity is filled with soda lime. The disposable surgical smoke purifier can efficiently remove organic polluted gas, carbon monoxide, carbon dioxide, viruses and cell debris and the like from surgical smoke, a safe surgical environment is thus provided for patients and medical staffs, and at the same time, the disposable surgical smoke purifier can be only used for one time for one patient so as to avoid cross infection. The purifier is small in size, simple in structure and convenient to use.

Description

technical field [0001] The invention relates to the technical field of gas purification, in particular to a disposable surgical smoke purifier. Background technique [0002] At present, there are four kinds of protective methods for surgical fumes, each of which has certain deficiencies. (1) Choose a suitable mask: Standard surgical masks cannot provide effective protection for the wearer in surgical smoke. It usually only filters out particles above 5 μm, while 77% of the particles in surgical smoke are smaller than 1.1 μm in diameter. (2) Negative pressure suction system: The suction device must be placed within the range of 2.54-5.08cm from the smoke source to effectively suck the smoke. If it exceeds this range, the effect will be halved. The standard suction device is not equipped with a high-performance filter in order to prevent clogging, and the sucked smoke only enters the suction bottle. When the negative pressure stops, the smoke may disperse. (3) Smoke exhaust ...
