Description

Technical Field

[0001] The utility model belongs to the technical field of nasal mask devices, and particularly relates to a nasal mask for anesthesia. Background Technique

[0002] For the nasal mask for anesthesia, the anesthetic generated by the anesthesia ventilator is inhaled into the body by the patient after passing through the nasal mask, reducing the loss of the anesthetic and making the anesthetic connecting pipe more convenient to connect with the patient.

[0003] At present, during the use of the existing nasal mask for anesthesia, the connection between the catheter joint of the nasal mask and the external pipe is relatively cumbersome. During the connection process, it is necessary to forcefully insert the pipe joint into the internal part of the external pipe. Such a connection method causes inconvenience for medical staff to apply force due to the small volume of the nasal mask during connection, and it is also prone to looseness, resulting in air leakage. Therefore, we propose a nasal mask for anesthesia. Content of the Utility Model

[0004] The purpose of the utility model is to provide a nasal mask for anesthesia to solve the existing problems mentioned in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A nasal mask for anesthesia, including a nasal mask body, a connection head, and a movable ventilation pipe.

[0006] Preferably, one end of the ventilation pipe close to the movable ventilation pipe is fixedly and hermetically connected by gluing with a corrugated rubber sleeve. A top spring is arranged inside the corrugated rubber sleeve. The end of the corrugated rubber sleeve is fixedly and hermetically connected by gluing with a first sealing ring. A second sealing ring is arranged at one end of the external pipe inserted into the connection head.

[0007] Preferably, limiting sliding grooves are provided on the inner walls of both sides inside the connection head. Limiting sliding blocks are fixedly arranged on the outer sides of both ends of the movable ventilation pipe extending into the connection head. The limiting sliding blocks extend into the limiting sliding grooves and are slidably connected with their inner walls. A return spring is arranged inside the limiting sliding grooves. Both ends of the return spring are fixedly connected with one end inner wall of the limiting sliding groove and one side of the limiting sliding block respectively.

[0008] Preferably, a fixing plate is fixedly installed on one outer side of the connector head, and a dial plate is fixedly installed on the outer periphery of one end of the movable through pipe extending outside the connector head, and the dial plate corresponds to the position of the fixing plate.
