Detailed Description
The following are specific examples of the present invention and further describe the technical solutions of the present invention, but the present invention is not limited to these examples.
Example 1
A portable respirator comprises a main machine, a breathing pipeline 7, a pressure release valve 8, a breathing valve 9, a wet heat exchanger 10, a pressure measuring pipe 14, an air source connecting pipe 15 and an air source 17. One side of the main machine is provided with a main machine driving gas input port 1, a main machine pressure measuring port 2 and a main machine gas outlet 3, and the other side of the main machine is provided with an air inlet 18, a power socket 19 and a power switch 20.
The main machine is communicated with an air source 17 through an air source connecting pipe 15, a main machine driving air input port 1 is connected with an air source connecting pipe plug end 4, and an air source connecting pipe plug end 16 is communicated with the air source 17.
The main machine pressure measuring port 2 is connected with the pressure measuring tube device end 5, and the bare end 13 of the pressure measuring tube is connected with the patient end pressure measuring port 12 of the breather valve 9.
The air outlet 3 of the main machine is connected with a breathing pipeline connecting port 6, the patient end of the breathing pipeline 7 is provided with a pressure release valve 8, the patient end of the pressure release valve 8 is provided with a breathing valve 9, the patient end of the breathing valve 9 is connected with a wet heat exchanger 10, and the patient end of the wet heat exchanger 10 is connected with a breathing mask 11 or a tracheal cannula.
Example 2
The present embodiment is different from embodiment 1 in that: the breather valve 9 includes a first valve cover 91, a first one-way diaphragm 92, a first umbrella-shaped diaphragm 93, and a valve body 94. The first valve cover 91 is a movable valve cover, a first one-way diaphragm 92 and a first umbrella-shaped diaphragm 93 are arranged at the device end in the valve body 94, and the first umbrella-shaped diaphragm 93 is arranged at the inner side of the first one-way diaphragm 92. When a patient inhales, the first valve cover 91 drives the first one-way diaphragm 92 and the first umbrella-shaped diaphragm 93 to press the valve body 94 tightly, and when the patient exhales, the first valve cover 91 drives the first one-way diaphragm 92 and the first umbrella-shaped diaphragm 93 to leave the valve body 94. When the patient inhales gas, the first umbrella-shaped diaphragm 93 is opened, and the gas flow passes through; when breathing out, the first umbrella-shaped diaphragm 93 and the first one-way diaphragm 92 block the airflow.
Example 3
The present embodiment is different from embodiment 2 in that: valve body 94 includes an air outlet 941, an air outlet 942, a patient end pressure measurement port 12, an emergency vent port 944, a second umbrella diaphragm 945, a second one-way diaphragm 946, and a second valve cover 947. The gas outlet 941 is connected to the heat and moisture exchanger 10 for delivering gas to the patient. The emergency vent 944 is provided with a second umbrella-shaped diaphragm 945, a second one-way diaphragm 946 and a second valve cover 947 in this order from inside to outside.
The gas exhaled by the patient is exhausted to the atmosphere through exhaust port 942. One end of the pressure measuring tube 14 is inserted into the patient end pressure measuring port 12, and the other end is connected with the air duct pressure sensor in the host machine, so that the real-time pressure of the respiratory air duct patient end is monitored.
By unscrewing the second valve cover 947, the patient can breathe spontaneously through the emergency vent 944 and inhale ambient air, which is suitable for situations where the patient can breathe spontaneously and the device fails or stops breathing due to a mid-section of the air supply.
Example 4
The present embodiment is different from embodiment 1 in that: the air source 17 is a medical oxygen supply device with the volume below 10L, a 40L oxygen bottle or a centralized oxygen supply system.
Finally, the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting, and other modifications or equivalent substitutions made by the technical solutions of the present invention by those of ordinary skill in the art should be covered within the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solutions of the present invention.
