Abstract
The utility model provides a first-aid breathing mask, which comprises a mask, wherein a sealing ring is fixed on the surface of the lower end of the mask; an air inlet nozzle is arranged on the upper side of the mask; the side surface of the mask is provided with an air outlet; the inner side of the face mask is connected with a bidirectional resistance sheet through a spring and a shaft, and the two resistance sheets of the bidirectional resistance sheet are respectively positioned at the air inlet nozzle and the air outlet hole. When the air-permeable plastic bag is used, a rescuer blows air from the air inlet nozzle, blows the blocking piece on one side of the air inlet nozzle of the M-shaped bidirectional blocking piece open, and the spring stretches to enable the blocking piece on the other side to be blocked at the air outlet, so that the unidirectional circulation of the air is realized. The rescuer stops blowing, and when preparing to take a breath and blow next time, "M" type two-way resistance piece spring kick-backs, blocks and fills in the air cock, opens the venthole, prevents that the gas of patient's exhalation from getting into the rescuer health, has solved the problem that the disease probably spread among the rescue process. Furthermore, when the rescuer is not blowing out air, the air outlet is in an open state, and when the patient can breathe by himself, the breathing process of the patient is not obstructed.
Description
Technical Field
The utility model belongs to the technical field of medical instrument, specifically belong to an emergency respirator.
Background
At present, doctors still adopt a mode of making patients breathe passively when emergently rescuing patients with sudden spontaneous dyspnea or respiratory arrest, and the mode mainly comprises 'mouth to mouth' or using a breathing mask. Although there are many technical solutions in the patent literature regarding emergency breathing masks, most of them fail to be converted into practical products for medical technology applications; during medical first aid, artificial respiration or a simple disposable breathing mask is adopted; the simple breathing mask in the prior art cannot effectively protect the rescue workers and the patients from the invasion of cross-spread diseases.
SUMMERY OF THE UTILITY MODEL
The utility model provides a first aid respirator to reach the personnel of carrying out rescue work of protecting in carrying out rescue work, prevent the purpose of disease cross propagation.
In the technical scheme of the utility model, the first-aid breathing mask is characterized in that the first-aid breathing mask comprises a mask body, and a sealing ring is fixed on the surface of the lower end of the mask body; an air inlet nozzle is arranged on the upper side of the mask; the side surface of the mask is provided with an air outlet; the inner side of the face mask is connected with a bidirectional resistance sheet through a spring and a shaft, and the two resistance sheets of the bidirectional resistance sheet are respectively positioned at the air inlet nozzle and the air outlet hole.
Furthermore, the mask is integrally formed, and the structure is that the vertical wall at one side is connected with an arc-shaped top surface; the air inlet nozzle is positioned on one side of the arc-shaped top surface close to the vertical wall, and the air outlet hole is positioned on the vertical wall.
Furthermore, the two-way resistance sheet is of an M shape, two outer side faces respectively correspond to the air inlet nozzle and the air outlet hole, a spring is horizontally connected to the inner wall of the mask at one side of the middle of the M shape, a shaft is installed at the middle of the M shape, and the end part of the shaft is connected into the mask.
Furthermore, the air inlet nozzle extends upwards, a circle of bulges are arranged on the outer wall of the air inlet nozzle, and the bulge direction faces one side of the mask.
The utility model has the advantages that:
when the emergency breathing mask is used, a rescuer blows air from an air inlet nozzle, blows off a blocking sheet at one side of the air inlet nozzle of an M-shaped bidirectional blocking sheet, stretches a spring, and blocks a blocking sheet at an air outlet, so that unidirectional circulation of the air is realized, and the air is effectively sent into the lung of a patient.
