1.     The Anesthesia Machine Introduce:

The anaesthetic machine is a mechanical circuit to the patient's alveoli, the formation of anesthetic gas subpressurization, dispersal to the blood, the central nervous system directly inhibited, resulting in the effect of general anesthesia. The anaesthetic machine is a semi-open anaesthetic device. It is mainly composed of liquid tank, ether adjustment switch, folding air box and suction, exhalation one-way flaps and bellows.

2.     About Anesthesia Machine Battery Pack Requirements:

The anaesthetic machine spare battery requires the municipal power failure situation can work continuously for more than 8 hours, the cycle life requirements reached 1000 times, I Division uses imported Sanyo electric core to achieve the work requirements of the anaesthetic machine.

3.     About CTECHI Make Battery Pack Solution of Anesthesia Machine

Anesthesia machine lithium battery protection

Lithium battery: 18650 lithium ion battery;

Battery overcharge function: Add charger between P+ and P- to charge the battery. When the voltage is charged to 16.8±0.05V (can be designed according to requirements), the protection circuit operates, the charging path is turned off, and overcharge protection is realized.

Battery over-discharge protection function: Connect the load between P+ and P- to discharge the battery. When the battery voltage drops to 12V±0.1V (can be designed according to requirements), the protection circuit operates, shuts off the discharge path, and realizes over-discharge protection;

Short-circuit protection function: When P+ and P- are short-circuited, the protection circuit will act quickly within 5-50uS, cut off the path and realize short-circuit protection;

Overcurrent protection function: When the voltage of the B- terminal and the P- terminal reaches (0.15±0.02V), the protection circuit will act quickly within 5-26ms to cut off the path and realize overcurrent protection.

Temperature performance

Discharge temperature range: -10 ° C - 60 ° C

Charging temperature range: 0°C—40°C

Storage temperature: 3 months: -20 ° C - 45 ° C 1 month: -20 ° C - 60 ° C
