The material of the housing body 1 and the rear cover 11 includes ABS plastic.

The utility model discloses the product theory of operation as follows:

when the key 5 is pressed, the current generated by the three battery boxes flows through the key 5 and flows to the inductor and the relay, and respectively reaches the 52 single-chip microcomputer through the inductor and the relay, the current passing through the inductor is used for the 52 single-chip microcomputer to count in a timing mode, and the current passing through the relay is used for the 52 single-chip microcomputer to supply power integrally; however, because the inductor has phase lag, namely a time delay function, the current passing through the relay reaches the 52 single-chip microcomputer earlier than the current passing through the inductor, the design ensures that the whole system is powered on and then can normally perform a timing and counting function, and meanwhile, the relay can also ensure that the current of the three-section battery box can still continue to supply power to the 52 single-chip microcomputer through the relay after the key 5 is disconnected;

then the 52 single chip microcomputer and a timing counter in the 52 single chip microcomputer start working, the time when the 52 single chip microcomputer receives the current from the inductor for the first time is taken as an initial time value, the timing counter starts timing from 0, and a time value is displayed on a liquid crystal display screen I10 of an LCD 0808;

if the key 5 is pressed again within 10 seconds, the value of the timing counter is cleared and counted again until the key 5 is pressed next time, and the process is repeated; after the keys 5 are pressed twice or more than twice, the 52 singlechip records the time interval between the keys 5 which are pressed twice, divides the time interval value by 60 to obtain the pressing frequency per minute, and displays the pressing frequency value on the LCD0802 liquid crystal display screen II in real time;

if the key 5 cannot be pressed again within 10 seconds, the 52 single chip microcomputer sends an instruction to control the relay to stop working, the relay can cut off the current sent to the 52 single chip microcomputer by the three battery boxes, and the whole breathing air bag timing counter is completely powered off and stops working;

the design ensures that the timing counter of the breathing air bag can be directly used when in use without adding extra switching equipment, removes the switching process and wins time for rescuing patients; after the breathing air bag timing counter is used, the whole system is only required to be automatically powered off, so that the energy of medical personnel can be saved, and the electric quantity of batteries in the three battery boxes can be saved;

the breathing air bag 14 is pressed for 1 time in 6 seconds generally, so when a timing counter in a 52-chip microcomputer works, in the timing process, under the condition that the timing counter of the whole breathing air bag is not powered off, the interval between two adjacent pressing of the key 5 is not within 6 +/-0.5 seconds, and the LED lamp 7 can emit red light as a warning; otherwise, the LED lamp 7 emits green light to indicate normal operation.

When the product of the utility model is used, firstly, 3 sections of No. 5 batteries are installed on the timing counter of the breathing air bag, so as to ensure the timing counter of the breathing air bag to work normally; then, the first fastening belt 4, the second fastening belt 6 and the slide fastener 3 are used for fixing the key 5 on the thumb, the breathing air bag 14 is held by hands, and the key 5 is kept between the pressing part of the breathing air bag 14 and the thumb; then the breathing air bag 14 is pressed or pinched, the key 5 is also touched at the moment, so that the timing counter of the breathing air bag starts to work, the condition of the LED lamp 7 and the numerical values on the LCD0802 and LCD0802 liquid crystal display screens I and II are observed at any time, and the breathing air bag 14 is pressed within 6 +/-0.5 as much as possible; and finally, after the treatment is finished, unfastening the first lacing tape 4 and the second lacing tape 6, taking down the button 5 on the thumb, and wiping the breathing air bag timing counter with alcohol for disinfection.

The above are all embodiments of the present invention, and any changes and substitutions without inventive labor in the claims of the present invention are within the protection scope of the present invention.
