Abstract
The utility model discloses a first-aid breathing mask, which comprises a manual air pump, a check valve, an air bag, a pressure switch, an ejector and a mask; the inlet of the check valve is connected with the manual air pump, and the outlet of the check valve is connected with the inlet of the air bag; the outlet of the air bag is connected with the working fluid inlet of the ejector through a pressure switch; the ejector fluid inlet of the ejector is connected with the mask, and the outlet of the ejector is communicated with the atmosphere; pumping air into the air bag by a manual air pump, so that the pressure in the air bag is increased to 1.2-1.3 times of the air suction pressure of the lung; the pressure switch is set to be opened when the pressure reaches 1.2 times of the lung suction pressure, so that the oxygen is ensured to be continuously uninterrupted. The utility model utilizes the manual air pump to control the air flowing direction in the ejector to assist the inspiration-expiration process of the patient, thereby replacing the artificial respiration. The utility model discloses can constantly carry oxygen for patient in succession, can continuously carry out artificial respiration, can avoid the production of awkward mood, can reduce the risk that the disease propagated again.
Description
Technical Field
The utility model belongs to the medical emergency field, in particular to first aid respirator.
Background
When people cannot breathe spontaneously or breathe weakly due to accidents or diseases in non-medical places, artificial respiration is required to be carried out immediately so as to ensure that oxygen is supplied to patients uninterruptedly and prevent ischemia and hypoxia injuries of important organs. Artificial respiration often requires mouth-to-mouth or mouth-to-nose insufflation. However, this may create a certain embarrassment and may increase the risk of disease transmission.
Disclosure of Invention
For solving the existing problems, the utility model discloses a first-aid respirator that can avoid the awkward mood to produce, can reduce the risk of disease propagation again is designed.
In order to achieve the above purpose, the technical solution of the present invention is as follows: a first aid breathing mask comprises a manual air pump, a check valve, an air bag, a pressure switch, an ejector and a mask; the inlet of the check valve is connected with the manual air pump, and the outlet of the check valve is connected with the inlet of the air bag; the outlet of the air bag is connected with the working fluid inlet of the ejector through a pressure switch; the ejector fluid inlet of the ejector is connected with the mask, and the outlet of the ejector is communicated with the atmosphere;
the manual air pump pumps air into the air bag, so that the pressure in the air bag is increased to 1.2-1.3 times of the air suction pressure of the lung;
the check valve is used for preventing the gas in the air bag from generating backflow;
the air bag is used for storing air for emergency treatment and ensuring air supply in the rescue process;
the pressure switch is set to be opened when the pressure reaches 1.2 times of the lung suction pressure, so that the air bag is communicated with the working fluid inlet of the ejector, and the oxygen is ensured to be continuously uninterrupted.
Furthermore, the ejector is arranged on the face mask, and the air inlet of the face mask is communicated with the ejection fluid inlet of the ejector to form a whole.
Compared with the prior art, the utility model discloses following beneficial effect has:
the utility model utilizes the manual air pump to control the air flowing direction in the ejector to assist the inspiration-expiration process of the patient, thereby replacing the artificial respiration. The utility model discloses can constantly carry oxygen for patient in succession, solve artificial respiration and can not last and effectively carry out this shortcoming. Meanwhile, the embarrassing emotion can be avoided, and the risk of disease transmission can be reduced.
Drawings
Fig. 1 is a schematic diagram of the present invention.
In the figure: 1. the manual air pump 2, the check valve 3, the gasbag 4, the pressure switch 5, the ejector 6, the face guard.
Detailed Description
In order to facilitate understanding of the technical means and objectives of the present invention, the following description is further provided with reference to the accompanying drawings.
As shown in fig. 1, the emergency breathing mask comprises a manual air pump 1, a check valve 2, an air bag 3, a pressure switch 4, an ejector 5 and a mask 6; the inlet of the check valve 2 is connected with the manual air pump 1, and the outlet of the check valve 2 is connected with the inlet of the air bag 3; the outlet of the air bag 3 is connected with the working fluid inlet of the ejector 5 through a pressure switch 4; an injection fluid inlet of the ejector 5 is connected with the face mask 6, and an outlet of the ejector 5 is communicated with the atmosphere;
the manual air pump 1 pumps air into the air bag 3, so that the pressure in the air bag 3 is increased to be 1.2-1.3 times of the air suction pressure of the lung;
the check valve 2 is used for preventing the gas in the air bag 3 from generating backflow;
the air bag 3 is used for storing air for emergency treatment and ensuring air supply in the rescue process;
the pressure switch 4 is set to be opened when the pressure reaches 1.2 times of the lung suction pressure, so that the air bag 3 is communicated with the working fluid inlet of the ejector 5, and the oxygen is ensured to be continuously uninterrupted.
Furthermore, the ejector 5 is arranged on the face mask 6, and the air inlet of the face mask 6 is communicated with the ejection fluid inlet of the ejector 5 to form a whole.
The working principle of the utility model is as follows:
when in use, the mask 6 is tightly buckled at the mouth and nose of a patient by hands, and the outlet of the ejector 5 is blocked by fingers. The other hand operates the manual air pump 1 to increase the air pressure in the air bag 3 to reach the pressure of the opening of the pressure switch 4. Air in the air bag 3 enters the face mask 6 through the pressure switch 4 and the working fluid inlet of the ejector 5, so that the aim of assisting the patient in inhaling is fulfilled. When the fingers blocking the ejector 5 are loosened, the air from the air bag 3 drives the ejector 5 to work to form an ejection effect, so that the gas in the mask 6 is discharged, and the aim of assisting the patient to exhale is fulfilled. The frequency of exhalation and inhalation is regulated by a finger blocking the outlet of the eductor 5.
Although specific embodiments of the present invention have been described above, it will be appreciated by those skilled in the art that these are merely examples, and that various changes and modifications can be made in the embodiments of the invention without departing from the spirit and scope of the invention.
