Description

Technical Field

[0001] The invention belongs to the technical field of myocardial infarction emergency rescue, and specifically refers to a breathing device for myocardial infarction emergency rescue. Background Art

[0002] Patients with myocardial infarction will develop coronary atherosclerosis, which will cause blood vessel stenosis and blood circulation obstruction. If the plaques in the blood vessels fall off and block the blood vessels, it will lead to poor blood circulation, ischemia and hypoxia, which will cause the patient to experience symptoms such as clenching teeth and clenching jaws.

[0003] When a patient has a heart attack, an emergency breathing mask is needed. The breathing mask transfers the oxygen needed for breathing from the storage tank to the human lungs to relieve the symptoms of a heart attack. If the patient has spontaneous breathing, nasal oxygen is the first choice, which can effectively improve myocardial oxygen supply. If the patient's breathing stops or is extremely weak, cardiopulmonary resuscitation is required to maintain oxygen supply through the mouth. Existing oxygen masks are difficult to keep the mouth airway open when the patient's teeth are clenched, and medical staff need to manually open the patient's mouth and keep the airway open, which is very inconvenient.

[0004] In addition, existing oxygen masks cannot detect the patient's spontaneous breathing status. When oxygen is given through the nose, if the patient does not have the ability to breathe independently, continuous oxygen supply can easily lead to excessive pressure and cause damage to the patient's lungs.

[0044] When in use, the cavity door 51 is opened to take the mask body 1 out of the storage cavity 50, and then the patient's oral cavity is manually opened, and two bite plates 24 that fit together are inserted into the patient's mouth, and the upper and lower teeth of the patient are quickly engaged in the engagement grooves 27 of the two medicine plates through the triangular guide portion 26, and then the mask body 1 is fixed to the patient's face through the elastic band 13. If the patient has spontaneous breathing, the first control valve 34 is opened, the second control valve 35 is closed, and then the oxygen supply device 2 is started to deliver oxygen into the nasal oxygen supply cavity 5 through the three-way pipe 11 and the first air inlet 9. Oxygen is supplied through the nose, and the zeolite molecular sieve in the adsorption cavity 32 can adsorb the carbon dioxide exhaled by the patient. If the patient stops breathing or is extremely When the patient's air is weak, at this time, open the second control valve 35, rotate the screw part 21 to drive the adjusting screw 18 to rotate, and the adjusting screw 18 drives the threaded slide 20 to slide along the adjusting screw 18 and the strip through hole 17, and the bite plate 24 on the bottom wall of the threaded slide 20 moves away from the bite plate 24 on the bottom wall of the fixed seat 19, thereby stretching the patient's mouth and keeping the airway open, and then start the oxygen supply device 2, and send oxygen into the oral oxygen supply chamber 6 through the three-way pipe 11 and the second air inlet 10, and maintain the oxygen supply by sending air through the mouth. When supplying oxygen through the mouth, the first control valve 34 can be adjusted down, and there is no need to completely close the first control valve 34. Since the patient's mouth remains open, if the patient cannot breathe independently, the oxygen sent into the nose will overflow from the patient's mouth.When supplying oxygen, the speed regulating motor 54 is started through the control panel 46, and the speed of the speed regulating motor 54 is adjusted. The speed regulating motor 54 drives the sprocket 53 to rotate, the sprocket 53 drives the chain 52 to rotate, and the chain 52 drives the trigger block 55 to move accordingly. When the trigger block 55 is transmitted to the side of the sprocket 53 away from the one-way push member 56, the one-way push member is not subject to external force at this time. Under the pulling force of the reset spring 44, it is maintained at the upper part of the pressing cavity 40. At this time, the elastic airbag 38 is not compressed. When the trigger block 55 rotates from the upper end to the one-way push member 56 along with the chain 52 When the push member is pushed toward the push member, the inclined surface of the active push plate 62 is close to the inclined surface of the driven push plate 61, and the active push plate 62 pushes the one-way push member 56 downward through the driven push plate 61, thereby driving the vertical slide plate 57 to move downward along the vertical slide hole 58. The vertical slide plate 57 drives the pressure plate 43 to move downward by pressing the connecting plate 59 to squeeze the elastic airbag 38, so that the oxygen in the elastic airbag 38 is sent to the three-way pipe 11 through the air supply hose 3 to supply oxygen. When the trigger block 55 pushes the one-way push member 56 downward, the one-way push member 56 drives the trigger rod 64 The trigger rod 64 moves downward synchronously to approach the trigger column 65. When the trigger rod 64 contacts the trigger column 65, as the trigger rod 64 continues to move downward, the fixed trigger column 65 pushes the trigger rod 64 to rotate in the direction of the chain 52. The trigger rod 64 drives the one-way pusher 56 to rotate away from the trigger block 55 and the chain 52 through the rotating shaft 60, thereby avoiding the trigger block 55. At this time, there is no obstruction under the trigger block 55. The chain 52 drives the trigger block 55 to move downward and separate from the one-way pusher 56. At this time, the reset spring 44 pulls the pressure plate 43 to move upward quickly After resetting, the elastic airbag 38 automatically recovers under the action of elastic force, and the oxygen in the oxygen storage component 39 is sucked into the elastic airbag 38 again through the oxygen absorption tube 45 for the next oxygen supply. The adjusting slide 68 can be driven to move up and down by screwing the second screw 67. The adjusting slide 68 drives the trigger column 65 to move up and down by adjusting the connecting rod 69 to adjust the height of the trigger column 65, thereby adjusting the stroke length of the downward movement of the pressure plate 43, and then adjusting the pressing degree of the elastic pressing airbag. The oxygen supply frequency can be adjusted by adjusting the speed of the speed regulating motor 54.
