  1. About Anesthesia Machine:

The anesthesia machine sends the anesthetic into the patient's alveoli through a mechanical circuit, forming a partial pressure of the anesthetic gas, and diffusing it into the blood, directly inhibiting the central nervous system, thereby producing a general anesthetic effect. The anesthesia machine is a semi-open anesthesia device. It is mainly composed of a liquid medicine tank, an ether regulating switch, a folding bellows, and a suction and exhalation one-way valve and a bellows.

  1. About Anesthesia Machine Battery Pack Requirements:

The backup battery of the anesthesia machine requires continuous power supply for more than 8 hours, and the cycle life requirement is 1000 times. Our company uses imported CTECHI or other brand batteries to meet the requirements of anesthesia machine work.

  1. 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
