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 novel anesthesia machine for an experiment. The simple novel anesthesia machine comprises an oxygenation pump, and further comprises a centrifugal tube with a liquid anesthetic, wherein the oxygenation pump is respectively communicated with a first gas flowmeter and a second gas flowmeter; the first gas flowmeter is communicated with the centrifugal tube through a centrifugal tube gas-intake duct; the second gas flowmeter is communicated with a tee joint; the tee joint is communicated with the centrifugal tube through a centrifugal tube discharge duct; the tee joint is further communicated with an anesthesia induction box or a respiration anesthesia box through an anesthesia duct. The simple novel anesthesia machine for the experiment disclosed by the invention has the advantages of being high in structural strength, stable in structure, safe, reliable, easy to control of concentration, cheap, fine and the like.

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...
