Description

A portable simple respirator for outdoor first aid

technical field

The utility model relates to the field of medical care and medical equipment, in particular to a portable simple respirator for outdoor first aid.

Background technique

If there is no spontaneous breathing, artificial respiration should be given immediately to ensure the uninterrupted supply of oxygen to the patient and prevent the irreversibility of vital organs due to hypoxia. Injury, as long as we give the patient a slightly larger air volume than normal during artificial respiration, so that the absolute value of the oxygen content is not less than that of spontaneous breathing, so that the oxygen supply to the vital organs of the body can be fully guaranteed, and it will not be caused by hypoxia. damage to vital organs. However, in outdoor situations, ordinary people are rarely able to accept artificial respiration, or artificial respiration may cause cross-infection, so it is more suitable and acceptable to use simple respirator.

Simple respirators, also known as resuscitation balls, are suitable for cardiopulmonary resuscitation and emergency situations requiring artificial respiration. This is especially useful in cases of choking, breathing difficulties or the need for increased oxygen delivery. However, the structure of the current simple respirator is complex, and the balloon is directly connected to various air valves. During the use process, the ordinary simple respirator is difficult to sterilize, and each part needs to be disinfected with disinfectant. At this time, the damage and corrosion consumption of the balloon is the largest. , and when using a simple respirator outdoors, the outdoor air condition is unknown, and severe weather may be encountered, such as smog, dense fog, etc., which is not conducive to the patient's use of the respirator. However, there is currently no simple respirator on the market that can be used in poor outdoor air conditions.

Pressure valve 7, a universal telescopic tube 9 is installed on the first air pipe 8, a second air pipe 14 is installed on the universal telescopic pipe 9, a breathing air valve 12 is installed on the second air pipe 14, and a first air valve is installed on the breathing air valve 12. Three trachea 17, a breathing mask 5 is installed on the third trachea 17, the breathing mask 5 includes an installation sealing head 10, and the third trachea 17 is inserted in the installation sealing head 10, and the stainless steel pipe 11 is installed at one end away from the first connector 6 There is a second connecting head 18, and the sealing rubber ring 3 is located between the second connecting head 18 and the balloon 1. The second connecting head 18 is installed with an intake valve 4, a first connecting head 6, a first air pipe 8, a million The telescopic tube 9 , the pressure limiting valve 7 , the second trachea 14 , the breathing air valve 12 and the third trachea 17 are integrally formed, and the second connector 18 and the intake valve 4 are integrally formed.

The intake valve 4 includes two limit bars 43 and an activated carbon air inlet 41. The activated carbon air inlet 41 is covered with a one-way sealing plate 44, and two clamping slots 42 are symmetrically installed on the one-way sealing plate 44, and The two clamping slots 42 are respectively clamped on the limiting blocking bars 43 .

The pressure limiting valve 7 includes a valve inner wall and a spring 73, a pressure relief hole 72 is formed on the side of the inner wall of the valve, and a circular hole is formed above the inner wall of the valve.

The breathing air valve 12 includes an air valve cavity, and two exhaust holes 15 are symmetrically opened on the upper side of the air valve cavity, and an exhaust plug 13 is inserted into each exhaust hole 15, and the two exhaust plugs 13 are installed together. There is a sealing circular plate 16 .

When the utility model is in use, all the structures except the balloon 1 are firstly sterilized, then the packaging of the disposable air bag 2 is unpacked, the first sealing ring 21 is opened, and the stainless steel tube 11 is inserted into the disposable air bag from the opening. In the bag 2, then squeeze the balloon 1, and then insert the stainless steel tube 11 and the disposable air bag 2 into the balloon 1. When inserting, the second sealing ring 22 is inserted into the balloon 1 first. After passing through the balloon 1, remove the second sealing ring 22, put the two sealing rubber rings 3 on the stainless steel tube 11 respectively and press the two ends of the disposable air bag 2, and then release the balloon 1. The air pressure of the bag 1 and the disposable air bag 2 are synchronized, then the first connector 6 and the second connector 18 are respectively sleeved on both ends of the stainless steel tube 11 and pressed tightly, and then the installation sealing head 10 of the breathing mask 5 is sleeved on the first connector. Press the three trachea 17 tightly, then stick the breathing mask 5 against the patient's mouth and nose, adjust the holding posture, and slowly squeeze and release the balloon 1 rhythmically.

When the balloon 1 is squeezed, the pressure inside the balloon 1 increases to squeeze the disposable air bag 2, and the disposable air bag 2 is positive air pressure, the air pushes the one-way sealing plate 44 to block the activated carbon air inlet 41, and the air pushes The sealing disc 16 is far away from the second trachea 14, and the sealing disc 16 drives the exhaust plug downward, blocking the exhaust hole 15, and the air flows into the breathing air valve 12 from the surrounding of the sealing disc 16, and flows from the breathing air valve 12 to the third air valve 12.

Finally, it flows into the disposable air bag 2 through the stainless steel tube 11. At the breathing place, the carbon dioxide in the patient's airway flows to the disposable air bag 2 with low air pressure, and the carbon dioxide enters the breathing air valve 12 through the third trachea 17, and the air pressure in the breathing air valve 12 When the air pressure rises, the second trachea 14 is blocked by the air pressure against the sealing disc 16, the sealing disc 16 pushes the exhaust plug 13 upward, the exhaust hole 15 is opened, and the carbon dioxide in the breathing air valve 12 is discharged out of the device.

Repeatedly squeezing and loosening the balloon 1, the air is continuously inhaled and fed into the patient's mouth, and the carbon dioxide is sucked out and discharged to the outside of the device to achieve the emergency function.

It is worth noting that when the squeezing force is too large and the squeezing speed is too fast, the air pressure in the device will rapidly increase beyond the critical value. At this time, the air pressure pushes the pressure limiting cap 71 to move upward, the spring 73 stretches, and the pressure limiting cap 71 When it rises to a certain height, the pressure relief hole 72 is exposed, which means that the air pressure exceeds the critical value, and the gas is discharged from the pressure relief hole 72 to keep the air pressure in the respirator within the critical value to avoid accidents during the emergency.

The above description is only a preferred embodiment of the present invention, but the protection scope of the present invention is not limited to this. Equivalent replacement or modification of the new technical solution and its utility model concept shall be included within the protection scope of the present utility model.
