Description

Technical Field

[0001] The utility model relates to the technical field of breathing masks, in particular to an anesthesia breathing mask. Background Art

[0002] Anesthesia breathing mask is a medical device used during anesthesia. Its main function is to provide oxygen and anesthetic drugs to patients during surgery or other medical procedures requiring anesthesia. This mask covers the patient's nose and mouth to ensure the effective delivery of anesthetic gas or oxygen while preventing pollutants in the air from entering the respiratory system. When using common anesthesia breathing masks, due to the diversity of patient conditions, anesthetized patients usually need to be intubated. However, the anesthesia breathing mask covers the patient's mouth and nose, making the intubation operation less convenient and interfering with the intubation process, thereby reducing the efficiency of the anesthesia operation and the safety of the patient.

[0003] For example, Chinese patent CN220090187U discloses an anesthesia breathing mask, which includes a connecting mask, a slot, a threaded groove, an attachment component, an air bag tube, an air supply pipe, a limit seat, a control valve, a fixing component and other components. By inflating the inside of the air bag tube, the air bag tube is expanded to adapt to patients with larger or fatter faces, thereby increasing the patient's comfort. However, during use, the anesthesia breathing mask usually needs to be connected to the mouth or nose of the anesthetized patient. Since the anesthesia breathing mask covers the patient's mouth and nose and is fixed, the intubation operation becomes inconvenient, which may affect the smooth progress of the intubation, making it inconvenient when intubation and anesthesia breathing are performed simultaneously, thereby reducing the efficiency of the anesthesia operation.

[0028] According to an embodiment of the utility model, an anesthesia breathing mask is provided.

[0029] The present invention is now further described in conjunction with the accompanying drawings and specific implementation methods. Figure 1-Figure 8 As shown, the anesthesia breathing mask according to the embodiment of the utility model includes an anesthesia breathing mask body 1, a connecting box 2 is arranged in the middle of the front of the anesthesia breathing mask body 1, a sealing mechanism 3 is arranged at one end of the connecting box 2 away from the anesthesia breathing mask body 1, the sealing mechanism 3 cooperates with the anesthesia breathing mask body 1 through a pressing mechanism 4, fixed tubes 5 are arranged at both ends of the connecting box 2, an oxygen and anesthetic gas mixing connecting tube 6 is arranged at one end of the fixing tube 5 away from the connecting box 2, a sealing cover 7 is arranged at one end of the oxygen and anesthetic gas mixing connecting tube 6 away from the fixing tube 5, and one side of the sealing cover 7 cooperates with the oxygen and anesthetic gas mixing connecting tube 6 through an adjusting mechanism 8; mounting seats 9 are arranged on all sides of the front of the anesthesia breathing mask body 1.

[0030] With the aid of the above-mentioned technical solution of the utility model, through the sealing mechanism 3 and the pressing mechanism 4, an effective intubation site can be provided when the patient needs intubation, and a stable seal can be maintained when intubation is not required, which not only meets the needs of anesthesia operation, but also improves the comfort and safety of the patient, and improves the working efficiency of the anesthesia breathing mask. By setting the sealing mechanism 3 and the air bag 10, the space between the anesthesia breathing mask body 1 and the patient's face can be effectively sealed to prevent the leakage of oxygen and anesthetic drugs, thereby ensuring that the patient obtains sufficient oxygen and anesthetic drug delivery, which helps to improve the anesthesia effect and make the anesthesia process more stable and controllable. By setting the adjustment mechanism 8, the sealing cover 7 can be conveniently fixed on the oxygen and anesthetic gas mixing connecting pipe 6, ensuring the sealing of the anesthesia breathing mask body 1 when the air supply pipe does not need to be connected, increasing the adaptability and flexibility of the anesthesia breathing mask, providing convenience for anesthesia operation, and also ensuring the safety and comfort of the patient.

[0031] In one embodiment, for the above-mentioned anesthesia breathing mask body 1, an airbag 10 is arranged on the back of the anesthesia breathing mask body 1; a fixing hole 11 is opened at one end of the mounting seat 9, and a fixing strap 12 is arranged inside the fixing hole 11, thereby realizing the fixation of the anesthesia breathing mask body 1 and facilitating the subsequent anesthesia breathing.

[0032] In one embodiment, for the above-mentioned sealing mechanism 3, the sealing mechanism 3 includes a sealing groove 301 opened at the end of the connecting box 2 away from the anesthesia breathing mask body 1, a fixed shaft 302 is arranged at the top of the sealing groove 301, a baffle 303 is arranged on the outer side of the circumference of the fixed shaft 302, and a sealing block 304 is arranged on the baffle 303 near the end of the connecting box 2; a sealing hole 305 matched with the sealing block 304 is opened inside the sealing groove 301, and a compression spring 306 is symmetrically arranged at the bottom end of the sealing groove 301, thereby realizing the sealing effect of the anesthesia breathing mask body 1 and improving the comfort and safety of the patient.

[0033] In one embodiment, for the above-mentioned pressing mechanism 4, the pressing mechanism 4 includes a fixed seat 401 arranged at one end of the connecting box 2 close to the baffle 303, and a limiting groove 402 is symmetrically opened inside the fixed seat 401, and a rotating shaft 403 matching with the fixed seat 401 is inserted in the limiting groove 402, and a rotating block 404 matching with the limiting groove 402 is sleeved on the outer side of the circumference of the rotating shaft 403; a pressing block 405 is arranged at the end of the fixed seat 401 away from the connecting box 2, a pressing spring 406 is arranged at the bottom of the pressing block 405, and a protrusion 407 is arranged on one side of the top of the pressing block 405, and the pressing mechanism 4 also includes a fixed block 408 arranged at the end of the baffle 303 away from the connecting box 2, and a groove 409 matching with the protrusion 407 is arranged at one end of the fixed block 408, so that the intubation operation can be implemented quickly and the work efficiency is improved.

[0034] The working principle of the pressing mechanism 4 is as follows: by rotating the rotating shaft 403, with the cooperation between the limiting groove 402 and the rotating block 404, the obstruction to the pressing block 405 is lost, and by pressing the pressing block 405, the pressing spring 406 at the bottom end of the pressing block 405 is compressed, and the protrusion 407 at the top end of the pressing block 405 loses the cooperation with the groove 409, thereby losing the resistance to the baffle 303.

[0035] In one embodiment, for the above-mentioned oxygen and anesthetic gas mixing connecting tube 6, a fixing groove 601 cooperating with the adjusting mechanism 8 is provided at the top of the oxygen and anesthetic gas mixing connecting tube 6 away from the fixing tube 5, and a slot 602 is provided at one end of the oxygen and anesthetic gas mixing connecting tube 6 close to the fixing groove 601, and an insert block 701 cooperating with the slot 602 is provided at one end of the sealing cover 7, and a limiting hole 702 cooperating with the adjusting mechanism 8 is provided on one side of the sealing cover 7, thereby increasing the functionality of the anesthesia breathing mask.

[0037] Working principle of the regulating mechanism 8: When the oxygen and anesthetic gas mixed connecting tube 6 contacts the sealing cover 7, the fixed column 802 will be compressed, and the slider 801 and the compression spring 803 will be compressed in turn, so that the spring 803 is in a tensioned state. When the fixed column 802 contacts the limiting hole 702, the compressed spring 803 will push the slider 801 and the fixed column 802 under the action of its own elastic force, and then the fixed column 802 is firmly clamped in the inside of the limiting hole 702.

[0038] In order to facilitate understanding of the above technical solution of the present invention, the working principle or operation method of the present invention in the actual process is described in detail below.

[0039] In actual application, the anesthesia breathing mask body 1 is worn on the patient's mouth and nose, and the fixing strap 12 is used for fixing. The sealing cover 7 is removed by adjusting the adjustment mechanism 8 (the working principle of the adjustment mechanism 8 is as shown above), so that the slot 602 and the plug block 701 lose coordination, and the oxygen and anesthetic gas gas pipelines on the anesthesia machine are connected to the oxygen and anesthetic gas mixing connecting pipe 6 and matched with the slot 602, and the anesthesia machine is started. After adjusting the flow and concentration of oxygen and anesthetic gas, the oxygen and anesthetic gas will be absorbed by the patient through the oxygen and anesthetic gas mixing connecting pipe 6 and the fixing pipe 5. When it is necessary to insert the gas pipeline into the patient's nose or mouth, the pressing mechanism 4 is pressed (the working principle of the pressing mechanism 4 is as shown above), and the baffle 303 loses the resistance of the pressing mechanism 4 and bounces outward under the action of the compression spring 306, thereby inserting the gas pipeline into the sealing hole 305, realizing the insertion of the patient's nose or mouth, and improving the anesthesia breathing efficiency.

[0040] In summary, with the aid of the above technical solution of the utility model, through the sealing mechanism 3 and the pressing mechanism 4, an effective intubation site can be provided when the patient needs intubation, and a stable seal can be maintained when intubation is not required, which not only meets the needs of anesthesia operation, but also improves the comfort and safety of the patient, and improves the working efficiency of the anesthesia breathing mask. By setting the sealing mechanism 3 and the air bag 10, the space between the anesthesia breathing mask body 1 and the patient's face can be effectively sealed to prevent the leakage of oxygen and anesthetic drugs, thereby ensuring that the patient obtains sufficient oxygen and anesthetic drug delivery, which helps to improve the anesthesia effect and make the anesthesia process more stable and controllable. By setting the adjustment mechanism 8, the sealing cover 7 can be conveniently fixed on the oxygen and anesthetic gas mixing connecting pipe 6, ensuring the sealing of the anesthesia breathing mask body 1 when the air supply pipe does not need to be connected, increasing the adaptability and flexibility of the anesthesia breathing mask, providing convenience for anesthesia operation, and also ensuring the safety and comfort of the patient.
