Anesthetic mask suitable for various oxygen supply systems

Abstract

The invention relates to an anesthetic mask suitable for various oxygen supply systems. The anesthetic mask comprises a mask body used for covering the mouth and nose of a user, at least one base is in sealed connection with the mask body through a fixed end, the external end of the base is in sealed connection with the downstream end of an inner pipe connector, the inner pipe connector extends in the space outside the mask body, an air inlet channel used for communicating the space inside the mask body with an inner hole of the inner pipe connector is arranged in the base, the inner pipe connector is sleeved with an outer pipe connector, the downstream end of the outer pipe connector is in sealed connection with the external end of the base, and an annular groove allowing an air supply pipe to be inserted therein is formed between the peripheral wall of the inner pipe connector and the peripheral wall of the outer pipe connector.

Description

technical field [0001] The invention relates to a medical device, in particular to an anesthesia mask suitable for various oxygen supply systems. Background technique [0002] Disposable anesthesia masks and oxygen inhalation masks are one of the commonly used medical devices in clinical practice. Disposable anesthesia masks are mainly connected with the breathing circuit to deliver anesthesia gas for patients to inhale anesthesia gas and provide auxiliary treatment for patients with respiratory failure. . Conventional anesthesia masks or oxygen inhalation masks can usually only be docked with a single-standard oxygen supply interface. This type of mask can only be applied to a single clinical application scenario. The air supply pipe of the anesthesia ventilator is usually connected to the air supply pipe of the anesthesia ventilator. When the operation is completed and the patient needs to recover in the ward, it is necessary to replace the oxygen inhalation mask or the a...

Problems solved by technology

Conventional anesthesia masks or oxygen inhalation masks can usually only be docked with a single-standard oxygen supply interface. This type of mask can only be applied to a single clinical application scenario. The air supply pipe of the anesthesia ventilator is usually connected to the air supply pipe of the anesthesia ventilator. When the operation is completed and the patient needs to recover in the ward, it is necessary to replace the oxygen inhalation mask or the anesthesia breathing mask with a smaller air inlet, and reinstall the mask. Fixed on the patient's mouth and nose, the replaced mask can be applied to the nasal oxygen supply system of the centralized supply pipeline in the existing hospital. This method requires the patient to remove the mask worn during the operation and wear a new one. Standard masks not only require heavy work for medical staff, but also interrupt oxygen inhalation during the operation, resulting in short-term hypoxia. In addition, changing masks also increases the financial burden on patients
