Problems solved by technology

[0003] Today's large hospitals are equipped with special indoor air purification equipment, but these machines basically deal with the overall indoor environment by suction air. This treatment method only purifies the indoor environment and does not fundamentally Prevent anesthesia waste gas from being absorbed by medical staff and patients, which threatens the life, health and safety of patients and medical staff; and generally adopts general-purpose breathing aids in terms of patient breathing, and patients have a great lack of comfort in medical treatment In addition, the existing filter equipment, the gas delivery process is continuous, easy to form a channel with less resistance in the filter material, most of the gas passes through the filter material through the channel with less resistance, and the utilization rate of most filter materials is low. After using for a while, the filtering effect will become worse, and the content of anesthetic gas in the filtered air will gradually increase

Embodiment 2

[0084] In the actual use process, it was found that the filtration of exhaled gas requires very high continuous processing capacity of the filter material. During the use process, it is very difficult to achieve complete filtration, and there is still the problem of leakage. Therefore, the handling of anesthetic gases is designed for storage of exhaled gases such as Figure 2-8 .

[0085] The gas exhaled by the patient is stored in a unit first, and after being stored by the unit airbag 500, the exhaled gas can be stored first, and then extracted for filtering operation, and the final elimination of anesthetic gas is carried out. In this way, the harmful gas with anesthetic components exhaled by the patient can not be filtered in the operating room to avoid the leakage of exhaled gas. Meanwhile, the form of the unit airbag 500 is convenient for storage and subsequent operation. If it is a large storage bag, the volume of exhaled gas is relatively large, and it is very inconv...

Embodiment 3

[0089] During the preparation of anesthetic gas, the actual active ingredient should be mixed with air and inhaled by the patient. If only one air bag, that is, the first air storage soft bag 12 is used for buffering, the actual inhalation uniformity of the anesthetic gas will be affected by the first storage soft bag. The size of the air soft bag, the intake velocity of anesthetic gas and air, the inhalation volume of the patient and the breathing rate will change. Therefore, the anesthetic gas that the patient needs to inhale is also unitized. The encapsulation operation of the gas can be the same as in the second embodiment, injecting the same amount of anesthetic gas and air into the unit airbag at the same time. Then the air in the unit airbag 500 is input into the first soft bag 12 at a certain rate.

[0090] In actual use, air can be filled into the unit airbag 500 in advance, so that the inflation of the unit airbag 500 can only be filled with a fixed amount of anesth...

Embodiment 4

[0114] The delivery of the unit airbag 500 requires a relatively precise position and time interval. Therefore, the winding assembly 400 is added, such as figure 2 and 8 shown.

[0115] The winding assembly 400 is used for storing and delivering the unit airbag 500 group;

[0116] The winding assembly 400 includes a first roller 410, a second roller 420, and a third roller 430; the first roller 410, the second roller 420, and the third roller 430 are driven by a chain, a gear or a belt, and are driven by a stepping motor The transmission rotates synchronously;

[0117] The first roller 410 winds the group of unit airbags 500;

[0118] The second roller 420 undertakes the unit airbag 500 group on the first roller 410, and the third roller 430 undertakes the unit airbag 500 group on the second roller 420;

[0119] The unit airbags 500 on the first roller 410, the second roller 420, and the third roller 430 are continuous;

[0120] Driven by a stepping motor, the rotation ...

Abstract

The present application discloses an anesthetic gas purification device, including purification equipment, and also includes a breathing mask assembly, a disposable mask, a first gas storage soft bag, and a second gas storage soft bag; the disposable mask is connected to the first gas storage soft bag through a pipeline The air bag and the second gas storage soft bag are connected; the first gas storage soft bag is used to buffer and store the anesthetic gas that the patient needs to inhale; the purification equipment includes a suction cylinder, a filter tank, and a suction one-way valve; the suction cylinder is Piston-type structure, one end has a suction check valve, and the end with the suction check valve sucks the gas in the second air storage soft bag; the filter tank communicates with the suction cylinder to make the suction As the piston in the barrel compresses the gas, the gas is able to flow out through the canister. The purification device has better filtering effect.

Description

technical field [0001] The invention relates to an air purification device for an anesthesia department, in particular to a filter and purification device for anesthesia gas. Background technique [0002] The anesthetic gas purification device uses purification substances to effectively physically and chemically filter the exhaled air of patients who have been treated with anesthetics to protect the personal safety of medical staff and patients. [0003] Today's large hospitals are equipped with special indoor air purification equipment, but these machines basically deal with the overall indoor environment by suction air. This treatment method only purifies the indoor environment and does not fundamentally Prevent anesthesia waste gas from being absorbed by medical staff and patients, which threatens the life, health and safety of patients and medical staff; and generally adopts general-purpose breathing aids in terms of patient breathing, and patients have a great lack of c...
