Problems solved by technology

[0002] As a medical method, anesthesia has been more and more recognized and used by the medical community. Since each patient's state is different, the required anesthesia effect is different, and different concentrations of anesthetic gas are required each time. The existing anesthesia machine does not It is convenient to adjust the concentration; in addition, when the exhaust gas spit out by the patient returns, a waste gas bag is needed. After anesthesia, it is quite inconvenient to process the waste gas in the waste gas bag. Sometimes too much waste gas will easily overflow and cause pollution.

Embodiment 1

[0023] Such as Figure 1 to Figure 3 As shown, the gas anesthesia device of the present invention includes a support plate 1 on which an anesthetic gas tank 2, an oxygen tank 3, a mixing mechanism, a waste gas recovery device and an anesthesia cover 6 are arranged; 2 is provided with a first air pipe 12, and is equipped with a first valve 13 and a first flow meter 14; the oxygen tank 3 is provided with a second air pipe 15, and is equipped with a second valve 16 and a second flow meter 17; also includes a third air pipe 18, the first air pipe 12 and the second air pipe 15 are both communicated with the third air pipe 18, and the third air pipe 18 is communicated with the mixing mechanism; the anesthesia cover 6 They are respectively communicated with the mixing mechanism and the waste gas recovery device. The gas anesthesia device of the present invention, through the cooperation of the support plate 1, the anesthetic gas tank 2, the oxygen tank 3, the mixing mechanism, the w...

Embodiment 2

[0025] On the basis of the above embodiments, in order to further better implement the present invention, the mixing mechanism includes a mixing tank 4 arranged on the support plate 1, one side of the mixing tank 4 communicates with the third air pipe 18, and the other Side is provided with output pipe 5, and this output pipe 5 communicates with described anesthesia cover 6 through the first flexible pipe; The top of described mixing tank 4 is provided with stirring motor 19, and the rotating shaft 20 of this stirring motor 19 stretches into mixing The tank 4 is equipped with corresponding bearings and sealing rings, and the rotating shaft 20 is provided with a disturbance vane 21 . After this design, the stirring motor 19 starts to drive the rotating shaft 20 to rotate, thereby driving the disturbance blade 21 to disturb. When the anesthetic gas and oxygen enter the mixing tank 4, they are evenly mixed under the disturbance of the disturbance blade 21, and the mixing is quite ...

Embodiment 3

[0028] On the basis of the above-described embodiments, in order to further better implement the present invention, the anesthesia cover 6 includes a cover body 23, and a silicone pad 28 that improves the sealing performance is provided at the part where the cover body 23 cooperates with the human face; The cover body 23 is provided with an anesthetic gas inlet 24 and a waste gas discharge port 25, the anesthetic gas inlet 24 is connected to the first hose, and the waste gas discharge port 25 is connected to a waste recycling device. When in use, cover the mouth and nose of the human face with the mask body 23, make the silicone pad 28 fit the face, the anesthetic gas mixed with the mixing tank 4 enters from the anesthetic gas inlet 24, and the exhaust gas produced by the patient's inhalation of the anesthetic gas is exhaled When the exhaust gas is transported to the exhaust gas recovery device through the exhaust gas discharge port 25, the pollution is greatly reduced.

Abstract

The invention relates to the field of medical apparatus and instruments, and especially relates to a gas anesthesia device that can adjust anesthetic concentrations according to needs and reduce the pollution of anesthetic waste gas. An anesthetic gas tank is provided with a first trachea which matches a first valve and a first flowmeter; an oxygen tank is provided with a second trachea which matches a second valve and a second flowmeter; the first trachea and the second trachea communicate with a third trachea that communicates with a mixing mechanism; and an anaesthetic mask respectively communicate with the mixing mechanism and a waste gas recycling device. Through the gas anesthesia device, the anesthetic gas tank and the oxygen tank respectively input anesthetic gas and oxygen to themixing mechanism so as to mix into the anesthetic gas with an appropriate concentration, and then the anesthetic gas can be conveyed to the anaesthetic mask for patients to use; the waste gas breathing out from the patients can be exhausted after treated by the waste gas recycling device; through the control of the first valve and the second valve, the proportion of the anesthetic gas and the oxygen can be conveniently adjusted, so that concentrations can be conveniently adjusted; and as the waste gas recycling device can recycle the waste gas breathing out from the patients, so that pollutioncan be greatly reduced.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a gas anesthesia device capable of adjusting anesthesia concentration according to requirements and reducing pollution of anesthesia waste gas. Background technique [0002] As a medical method, anesthesia has been more and more recognized and used by the medical community. Because each patient's state is different, the required anesthesia effect is different, and different concentrations of anesthetic gas are required each time. The existing anesthesia machine does not It is convenient to adjust the concentration; in addition, when the exhaust gas spit out by the patient returns, a waste gas bag is needed. After anesthesia, it is quite inconvenient to process the waste gas in the waste gas bag. Sometimes too much waste gas will easily overflow and cause pollution. Contents of the invention [0003] Aiming at the defects in the prior art, the present invention provides a gas anes...
