Problems solved by technology

Since the inner cavity of the anesthesia mask is also in a positive pressure state during the patient's exhalation process, the anesthesia gas will inevitably escape under the cooperation of the positive pressure of the anesthetic gas.
On the one hand, the escape of anesthetic gas will have an impact on the surgeon, which may lead to a decline ...

Embodiment Construction

[0020] Such as figure 1 and figure 2 As shown, a closed anesthesia mask of the present invention which can prevent anesthesia gas from escaping mainly includes a closed mask body 1 . An elastic fixing belt is provided on the mask body 1. After the mask body 1 is placed on the mouth and nose of the patient's face, the elastic fixing belt can be fastened by a buckle, and the silicone pad arranged around the mask body 1 can be used together. The close contact between the mask body 1 and the patient's face isolates the inner cavity of the mask body 1 from the outside world. Since both the elastic fixing band and the silicone pad are common technologies in this field, figure 1 and figure 2 are not shown.

[0021] In addition to the above-mentioned mask body 1, the present invention also includes a ventilation tube 3 and an air extraction tube 2 connected to the mask body 1 through a breathing valve. The ventilation tube 3 is connected to the output end of the anesthetic gas ...

Abstract

The invention relates to the field of anaesthesia auxiliary equipment, in particular to a closed anaesthesia mask capable of preventing anaesthesia gas from escaping. The closed anaesthesia mask comprises a mask body, a vent pipe and an air suction pipe, both the vent pipe and the air suction pipe are connected to the mask body through a breathing valve, and the breathing valve can automatically control the on-off of the vent pipe and the air suction pipe and the inner cavity of the mask body along with respiration of a patient; the breathing valve comprises a rigid pipe with one closed end and one opened end and a light foam ball arranged in the rigid pipe in a sliding mode; and the inner cavity of the rigid pipe is divided into a first cavity part and a second cavity part by the light foam ball, the first cavity part and the second cavity part are connected through a bypass pipe, and both a connecting port of the vent pipe and the second cavity part and a connecting port of the air suction pipe and the second cavity part can be blocked by the light foam ball sliding to the corresponding position. The closed anaesthesia mask can avoid various problems caused by the escape of anesthesia gas in the anesthesia process, and is simple in structure, easy to realize and convenient to control.

Description

technical field [0001] The invention relates to the field of anesthesia auxiliary equipment, in particular to a closed anesthesia mask which can prevent anesthesia gas from escaping. Background technique [0002] Inhalational anesthesia refers to an anesthesia method in which anesthetics are inhaled through the respiratory tract to inhibit the central nervous system, causing the patient to temporarily lose consciousness without feeling pain all over the body. It is the main method of general anesthesia. The depth of anesthesia is related to the partial pressure of the drug in the brain tissue. When the anesthetic drug is excreted from the body or metabolized in the body, the patient gradually regains consciousness without any sequelae. Because inhalation anesthesia has less metabolism and decomposition in the body. Most of them are excreted from the lungs in their original form, so inhalation anesthesia is easy to control, relatively safe and effective, and is a commonly us...
