Suction gas injection device of anaesthetic mask

Abstract

The invention relates to a medical instrument, and provides a suction gas injection device of an anaesthetic mask. The suction gas injection device of the anaesthetic mask comprises a bottle body anda balloon, wherein drug inlet and outlet openings are formed in two ends of the bottle body, and are sealed through covers; the balloon is connected with the drug inlet and outlet opening of one end of the bottle body; and the drug outlet of the other end of the bottle body is connected with a drug injection opening of the anaesthetic mask. The suction gas injection device of the anaesthetic maskis reasonable in design and simple in structure; the bottle body made of a glass material stores the drugs, the shortcoming that a plastic empty needle serves as a drug injection device in a traditional way, and is easily corroded is overcome effectively, the two ends of the suction gas injection device of the anaesthetic mask are sealed by the metal covers, thus, the corrosion resistance of the device is further enhanced, and secondarily, compared with plastic, the glass product is more environmentally friendly, and has less harm such as pollution of the glass product.

Description

Technical field [0001] The invention relates to the technical field of medical equipment, in particular to an anesthesia mask inhalation gas bolus. Background technique [0002] Inhalation anesthesia is a method of anesthesia often used in clinical practice. Most of this method is to supply volatile anesthetics with an anesthesia mask to the patient. The anesthetic is inhaled during the patient's breathing, and the anesthesia mask ( For example, the patent number of the present invention is 201620334515. The patent name is an anesthesia mask involved in a pediatric voluntary inhalation anesthesia mask.) The injection of anesthetics generally uses a disposable syringe as a bolus device to inject anesthesia into the anesthesia mask. Most of the drugs are ethers. These drugs are somewhat corrosive to plastic products, and long-term storage will more or less contaminate the drugs. At present, there are few special packaging devices for such drugs. Summary of the invention [0003] Th...

AI Technical Summary

Problems solved by technology

[0002] The inhalational anesthesia method is a kind of anesthesia method often used clinically. This method is mostly volatile anesthetic drugs combined with an anesthesia mask to supply the patient with drugs, and the anesthetic drugs are inhaled at the same time during the patient's breathing, while the clinical anesthesia mask ( For example, in the present invention, the patent number is 201620334515.X, and the patent name is an anesthesia mask involved in an anesthesia mask for children's self-inhalation). Generally, a disposable syringe is used as a push injection device to inject anesthesia drugs into the anesthesia mask, and anesthesia Drugs are mostly ethers. Such drugs are more or less corrosive to plastic products. Long-term storage will more or less pollute the drugs. At present, there are few dispensing devices for such drugs.
