Problems solved by technology

The high cost of existing medical anesthesia machines and commercial animal anesthesia machines brings unnecessary waste
Some laboratories have designed their own anesthesia machines, but the effect is poor, and the leakage of residual gas is serious, which is not good for the health of experimenters

Embodiment 1

[0023] Such as Figure 1~2 as shown,

[0024] 1. Air supply:

[0025] The gas flow supply of the present invention all comes from the aeration pump 2 . The aeration pump 2 has two outlets, one of which is introduced into the first gas flow meter 3 (250mL / min) through a conduit, and the flow rate can be adjusted to generate an air flow with a certain flow rate, which is introduced into the centrifuge tube through the inlet conduit of the centrifuge tube 6, the anesthetic gas can be generated; the other outlet is connected to the second gas flow meter 4 (1L / min) through the catheter, and the flow rate can be adjusted to generate an air flow with a certain flow rate, which is the same as the final gas flow through the centrifuge tube outlet 8 The anesthetic gas is mixed so that the anesthetic gas concentration can be diluted. Gas flow meters with two flow rates are used here, wherein the first gas flow meter 3 can easily fine-tune the gas flow rate, so as to facilitate the eff...

Abstract

The invention discloses a simple and new experimental anesthesia machine, which includes an oxygenation pump and a centrifuge tube provided with a liquid anesthetic. The oxygenation pump is respectively communicated with a first gas flowmeter and a second gas flowmeter. The meter communicates with the centrifuge tube through the centrifuge tube inlet conduit, the second gas flow meter communicates with the tee, the tee communicates with the centrifuge tube through the centrifuge tube outlet conduit, and the tee also communicates with the anesthesia induction box or the breathing anesthesia box through the anesthesia catheter. The invention has many advantages such as high structural strength, stable structure, safety and reliability, easy concentration control, high quality and low price.

Description

technical field [0001] The invention relates to the field of animal experiment devices, and more specifically relates to a simple and novel experimental anesthesia machine, which is suitable for anesthesia of small animals. Background technique [0002] The working principle of the respiratory anesthesia machine for animal experiments is to introduce the airflow into the anesthesia bottle through a mechanical circuit, and then promote the volatilization of the anesthetic agent, and the airflow carrying the anesthetic gas is introduced into the nasal cavity of the animal, and finally reaches all parts of the body through the animal's respiratory system and circulatory system. Thus, the central nervous system is directly inhibited, resulting in the effect of general anesthesia. The respiratory anesthesia machine is a semi-open device, which can be divided into several parts according to its working principle: air supply system, anesthetic agent volatilization system, anesthesi...
