Abstract
Description
Technical Field
[0001] This utility model relates to the field of breathing masks, and more specifically, to a breathing mask. Background Technology
[0002] A breathing mask is a device used to assist breathing or protect the respiratory system, widely used in medical, emergency, industrial, and aerospace fields. It typically consists of a mask body, a sealing gasket, a breathing valve, and connecting tubing. In the medical field, breathing masks can be used to treat respiratory diseases, such as providing oxygen therapy for patients with chronic obstructive pulmonary disease (COPD) and assisting patients with sleep apnea-hypopnea syndrome with non-invasive ventilation; in surgical anesthesia, they can deliver anesthetic gases and oxygen to patients; and in emergency situations, they can rapidly provide patients with high concentrations of oxygen.
[0003] Displacement of the anesthesia mask leading to a poor seal is a serious problem during patient anesthesia. The main function of the anesthesia mask is to deliver anesthetic gas and oxygen to the patient to maintain their anesthetic state and normal breathing during surgery. If the mask shifts and fails to seal properly, anesthetic gas leakage will occur, resulting in insufficient anesthetic gas dosage inhaled by the patient. This will affect the anesthetic effect, and the patient may experience loss of consciousness or pain perception during surgery. This not only causes suffering for the patient but also interferes with the normal progress of the surgery. Furthermore, leakage of anesthetic gas into the surgical environment can also pose health risks to medical staff.
[0004] How to design a breathing mask to improve these problems has become an urgent issue for those skilled in the art. Utility Model Content

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0024] Example, refer to Figures 1-6A breathing mask includes a mask body 1, with multiple strap frames 2 fixedly connected to the mask body 1. The strap frames 2 are evenly distributed on both sides of the mask body 1. An air supply valve 3 and an air outlet valve 4 are provided on both sides of the mask body 1, located between the strap frames 2 on the same side. An air inlet bellows 5 and an air outlet bellows 6 are provided on the mask body 1. A filter frame and a filter element 8 are provided inside the air supply valve 3, with the filter element 8 fitted to the filter frame. An air inlet hole 7 is provided at the end of the air inlet bellows 5, and the air inlet bellows 5 connects to the inner surface of the mask body 1 through the air inlet hole 7. The cover 1 is equipped with a sealing component and two symmetrically positioned strap frames 2, each with a first strap 10 and a second strap 11. Each of the first strap 10 and the second strap 11 is equipped with a fixing clip 12. The first strap 10 and the second strap 11 are movably connected to the strap frame 2 through the fixing clip 12. The ends of the first strap 10 and the second strap 11 are equipped with adjusting clips 13. Adjusting wheels 14 are rotatably connected to the outer side wall of the adjusting clip 13. The first strap 10 and the second strap 11 are both located inside the adjusting clip 13.
[0025] The sealing assembly includes an outer sealing strip 15 fixedly connected to the cover 1. Multiple sealing outer connecting pieces 17 are fixedly connected to the side wall of the outer sealing strip 15. The multiple outer connecting pieces 17 are evenly distributed on the outer sealing strip 15. A connecting rod 19 is fixedly connected to each end of the outer connecting piece 17. The connecting rod 19 is perpendicular to the outer connecting piece 17. The sealing assembly also includes a sponge layer 20 fixedly connected to the side wall of the outer sealing strip 15. A sealing coating is provided on the outer side wall of the sponge layer 20. The outer connecting pieces 17 are located between the outer sealing strip 15 and the sponge layer 20. Multiple inner connecting pieces 18 and inner sealing strips 16 are fixedly connected to the side wall of the sponge layer 20. The multiple inner connecting pieces 18 are equidistantly arranged on the sponge layer 20. The inner connecting pieces 18 are located between the sponge layer 20 and the inner sealing strip 16. The connecting rod 19 is located inside the sponge layer 20. The connecting rod 19 is non-contact with the inner connecting piece 18. A connection point 21 is provided between two outer connecting pieces 17. The connection point 21 is electrically connected to the external alarm assembly.
[0026] The working principle of this breathing mask is as follows: If the user needs anesthesia, the breathing mask is worn on the user's face. By pressing the outer sealing strip 15, the inner sealing strip 16 is made to fit tightly against the user's face. The adjustment wheel 14 is rotated to adjust to a comfortable position to complete the wearing of the breathing mask. At this time, due to the pressure between the mask body 1 and the user's face, the pressure is applied to the sponge layer 20, and the sponge layer 20 is compressed, so that the connecting rod 19 contacts its corresponding inner connecting piece 18, so that multiple outer connecting pieces 17 form a connected circuit, and the connected signal is transmitted to the external alarm component through the connection point 21, so that the alarm component is in a non-alarm state.
[0027] If the breathing mask is accidentally touched during anesthesia, resulting in a non-complete fit between the mask and the user's face, the non-fitted area loses pressure from the user's face, causing the inner connecting piece 18 and the connecting rod 19 to be in a non-contact state. This prevents the multiple outer connecting pieces 17 from forming a connected circuit. The external alarm component detects the circuit disconnection and issues an alarm to alert those around the user that the breathing mask has shifted. The mask can only continue to operate after it has been adjusted to a suitable position, preventing the user from regaining consciousness during anesthesia due to an incomplete seal of the breathing mask.
[0028] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
