Problems solved by technology

[0003] However, since the existing gas anesthesia mask is only a mask body connected to the airway, the size of the mask body is not adjustable and cannot fit patients with different face sizes, so there is a risk of anesthesia gas leakage. Although the existing technology There are technologies to improve the structure of the mask, but they all add a negative pressure device to prevent leakage and a gas anesthesia mask to absorb anesthesia gas outside the ordinary mask. The absorbed anesthesia gas is not used by the patient, and it still needs to go through professional procedures. The processing system carries out processing, resulting in resource fees, which is not conducive to environmental protection

Embodiment 1

[0031] A mask for gas anesthesia, see Figure 1-4 , including the inner cover 1, the inner cover 1 is used to wrap the nose of the patient, preferably, the inner cover 1 is fitted with a disposable face mask 3, and the face mask 3 and the inner cover 1 can be glued or magnetic connection, the face mask 3 is in direct contact with the patient's nose, and the face mask 3 is made of a soft material that does not chemically react with anesthetic gas. probability. The inner cover body 1 is a cover body structure made of hard material, which is used to wrap the nose. The edge of the cover body that is used for contacting the skin can be covered with a sealing sleeve or not. When the sealing sleeve is covered, Most of the anesthetic gas is absorbed by the nose. If the sealing sleeve is not set, the anesthetic gas leaked from the inner cover body 1 is absorbed by the patient's mouth, and the anesthetic effect of double absorption is realized.

[0032] The outer cover body 2 is provi...

Embodiment 2

[0040] A mask for gas anesthesia is basically the same in structure and working principle as in Example 1, except that the mask 3 is used to wrap the mouth, and the anesthetic gas is inhaled into the body of the patient from the mouth. The size of the mask 3 in this embodiment is It is larger than the face mask 3 of Example 1, and the anesthetic gas leaked from the inner cover body 1 into the outer cover body 2 is inhaled into the patient's body through the patient's nose.

Embodiment 3

[0042] An anesthesia device used in conjunction with the gas anesthesia mask of embodiment 1 or embodiment 2, see Figure 5 , including anesthesia gas supply machine 7 and oxygen tank 8, anesthesia gas supply machine 7 adopts anesthesia tank equipped with anesthesia gas, etc., oxygen tank 8 is filled with oxygen, as a backup for surgery, anesthetic gas supply machine 7 is connected with the first three-way pipe At one end, the second end of the tee is connected to the oxygen tank 8, the third end of the tee is connected to the air conduit 5, and the first and second ends of the tee are provided with a pressure gauge and a flow regulator.

Abstract

The invention belongs to the technical field of gaseous anesthesia equipment, and particularly relates to a mask for gaseous anesthesia and an anesthesia device.The mask for gaseous anesthesia comprises an inner mask body, an outer mask body is arranged outside the inner mask body, the outer mask body comprises an elastic framework rod and a telescopic curved mask body installed on the framework rod, and the outer mask body is provided with a large opening and a small opening; the size of the large opening is larger than that of the small opening, the small opening is sleeved with a size adjusting pipe, the inner mask body, the outer mask body and the face attaching mask are connected through a gas guide pipe, and the part, located outside the size adjusting pipe, of the gas guide pipe is used for being connected with an anesthetic gas providing machine. The inner mask body and the outer mask body have double anesthetic gas blocking effects, and nose inhalation and mouth inhalation are double anesthetic gas absorbing effects, so that waste and leakage of anesthetic gas are not caused, environmental pollution is avoided, and energy conservation and environmental protection are achieved.

Description

technical field [0001] The invention belongs to the technical field of gas anesthesia equipment, in particular to a gas anesthesia mask and an anesthesia device, and more particularly to a gas anesthesia mask and an anesthesia device that can reduce gas loss. Background technique [0002] Anesthesia is the use of drugs or other methods to reduce the pain of the patient to relieve the pain of the patient and achieve the purpose of painless treatment. Common clinical anesthesia methods are drug anesthesia or gas anesthesia. Common gas anesthesia drugs include isoflurane, desflurane, sevoflurane, etc. Gas anesthesia has the characteristics of short induction period and quick recovery. At present, the anesthesia devices used in conjunction with gas anesthesia include gas anesthesia masks, air tubes, anesthetic gas supply machines containing anesthetic gas, and auxiliary facilities such as oxygen tanks. Gas anesthesia masks, air tubes, and anesthetic gas supply machines are conne...
