Description

Technical Field

[0001] This utility model relates to the field of respiratory mask technology, and in particular to a respiratory mask for an anesthesia machine. Background Technology

[0002] An anesthesia machine is one of the tools for administering anesthesia. During general anesthesia, the amount of anesthetic gas inhaled can be controlled. The anesthesia machine delivers oxygen and anesthetic gas with controlled flow and concentration into a closed mask. During inhalation, the anesthetic gas mixture enters the breathing mask and then enters the patient's body. During exhalation, the mask is ventilated through a valve. This allows the anesthesia procedure to be completed for the patient.

[0003] For example, the Chinese patent with authorization announcement number CN215135382U discloses an anesthesia machine breathing mask, the working principle of which is "including a mask body, a breathing valve installed on the surface of the mask body, a mouth plug connected to the end of the breathing valve, fixing devices on both sides of the mask body, and a sealing ring installed on the surface of the mask body. This utility model, by setting a breathing valve on the surface of the mask body, facilitates the patient's mouth covering the mouth plug and exhaling through the breathing valve, thus making the patient more comfortable and relaxed when wearing the mask. The fixing devices on both sides of the mask body, using Velcro a and Velcro b to fix and limit the mask to the patient's head, make the mask fit the patient's face more stably and prevent anesthetic gas leakage; the disassembly mechanism allows for easy cleaning." "When using the mask, simply rotate the mask body to separate the ventilation tube from the connector to complete the disassembly, facilitating cleaning and disinfection of the mask for easy reuse." However, although the device has a quick-release structure that allows for the removal of the ventilation tube and facilitates initial cleaning and disinfection of the mask body, the sealing rings and Velcro are highly susceptible to contamination with bacteria, viruses, and other microorganisms during the thorough cleaning process after use. Since the existing quick-release structure cannot completely remove the sealing rings and Velcro, if only the removable parts are cleaned, these microorganisms attached to the sealing rings and Velcro will remain. When the mask is used again, these residual microorganisms are very likely to cause infection in subsequent users, seriously threatening the health and safety of patients and posing a potential threat to medical safety.

The T-shaped groove 20 has retaining grooves on both sides at one end that cooperate with the retaining ball 212.

[0019] When T-block 25 is inserted into T-groove 20, the retaining ball 212 will be engaged in the retaining groove inside T-groove 20 under the action of spring 29, achieving a stable connection and effectively preventing T-block 25 from sliding out of T-groove 20, ensuring the reliability of the connection of each component of mask 10. The cooperation of spring 29 and slider 210 allows retaining ball 212 to smoothly enter and exit the limiting groove 27 and retaining groove. While ensuring stable connection, it is also easy to disassemble. When disassembly is required, only a certain external force needs to be applied, and retaining ball 212 can compress spring 29 and disengage from retaining groove, achieving quick disassembly.

[0020] The restraint strap 14 is made of a flexible and elastic material.

[0021] The flexible material allows the restraint strap 14 to better conform to the contour of the patient's head, reducing pressure on the patient's head and improving patient comfort. Its elasticity allows the restraint strap 14 to stretch and contract to a certain extent according to the slight changes in the patient's head movements and breathing, always maintaining an appropriate tightness. It will not be too tight, causing discomfort to the patient, nor too loose, causing the mask 10 to be unstable. This ensures that the mask 10 can always fit closely to the patient's face during use, guaranteeing the normal functioning of anesthesia and breathing.

[0022] Both the breathing port 11 and the anesthesia tube port 12 are fixed to the mask 10 by threads.

[0023] Both the breathing port 11 and the anesthesia tube port 12 are fixed to the mask 10 by threads.
