Description

Technical Field

[0001] The present invention relates to the field of medical supplies, in particular to a portable first aid device for aspiration and suffocation. Background Art

[0002] Aspiration refers to the accidental entry of liquids, solid food, secretions, blood, or other substances into the airway during swallowing, whether eating or not. Aspiration is a common accidental condition in young children, the elderly, and some individuals with swallowing disorders, and it also occurs in everyday life for the general population. Aspiration is a leading cause of accidental death in children under five years old, particularly those between toddlers and two years old, with a high incidence and mortality rate. Aspiration is also a common complication in patients with swallowing disorders due to brain disease and stroke. Studies have shown that 34.3% of stroke patients are at risk of aspiration, with an aspiration rate as high as 30.5%. Aspiration pneumonia caused by aspiration can have a mortality rate of 40% to 50%. In severe cases, it can lead to sudden suffocation and even death. This not only reduces patient comfort, prolongs hospitalization, and increases financial burden, but also compromises recovery outcomes, causing unnecessary pain and financial burden for patients and their families.

[0003] The most mature first aid method at present is the Heimlich maneuver invented by Professor Heimlich, a senior American surgeon. Although the Heimlich maneuver has certain effects, it may also bring certain hazards, especially to the elderly. Because the elasticity and compliance of their chest and abdominal tissues are poor, it is easy to cause injuries, such as rupture, tearing and bleeding of abdominal or chest organs, rib fractures, etc. Therefore, when the airway is blocked, other methods should be used first to remove foreign objects. This method can only be used when other methods are ineffective and the patient's condition is urgent. However, there is currently no corresponding first aid equipment on the market, which also increases the difficulty of rescue. Summary of the Invention

[0004] In order to solve the above technical problems, the technical solution provided by the present invention is: a portable first aid device for accidental aspiration and suffocation, comprising a suction cup that can penetrate deep into the throat, a straw, and a negative pressure device arranged at the bottom of the straw, wherein the suction cup, the straw, and the negative pressure device are arranged in a through-connected manner; the suction cup is a hollow structure, and a foreign matter suction channel is provided through the middle thereof; the end of the suction cup away from the straw is provided with a mounting ring, and the surface of the end of the mounting ring away from the straw is provided with a light source assembly and a camera assembly; the straw is made of a bendable material, and the end thereof connected to the negative pressure device is provided with an anti-reflux assembly; the negative pressure device includes a negative pressure tube connected to the straw, a piston assembly that is pulled out to the other end is provided in the negative pressure tube, and a detachable tongue depressor assembly is provided outside the negative pressure tube.

[0005] Furthermore, the light source assembly is a plurality of lighting lamps embedded in the end surface of the mounting ring, and the lighting lamps are spaced apart to form a camera assembly mounting area.
