Experimental animal suffocation system

The experimental animal suffocation system combines isoflurane anesthesia and carbon dioxide anesthesia methods, which can perform both animal anesthesia and euthanasia, as well as animal anesthesia surgery. It is very suitable for experiments that require simultaneous organ retrieval. Introduction to Carbon Dioxide Anesthesia Carbon dioxide anesthesia is also called "Acidosis". When the carbon dioxide in the air inhaled by animals increases, the carbon dioxide partial pressure of alveolar air increases, and the carbon dioxide partial pressure of arterial blood also increases, so the respiration deepens and accelerates, and the pulmonary ventilation volume increases. Increased lung ventilation can increase carbon dioxide excretion, bringing the partial pressure of carbon dioxide in lung cell gas and arterial blood close to normal levels. But when the partial pressure of inhaled carbon dioxide increases beyond a certain level, lung ventilation cannot increase correspondingly, causing a significant increase in alveolar gas and arterial blood partial pressure of carbon dioxide, leading to inhibition of central nervous system activity, including respiratory center activity, causing breathing difficulties, headaches, dizziness, and even coma, leading to carbon dioxide anesthesia.

Introduction to carbon dioxide anesthesia

Carbon dioxide anesthesia is also called "Acidosis". When the carbon dioxide in the air inhaled by animals increases, the partial pressure of carbon dioxide in alveolar air increases, and the partial pressure of carbon dioxide in arterial blood also increases, so the respiration deepens and accelerates, and the pulmonary ventilation volume increases. Increased lung ventilation can increase carbon dioxide excretion, bringing the partial pressure of carbon dioxide in lung cell gas and arterial blood close to normal levels. But when the partial pressure of inhaled carbon dioxide increases beyond a certain level, lung ventilation cannot increase correspondingly, causing a significant increase in alveolar gas and arterial blood partial pressure of carbon dioxide, leading to inhibition of central nervous system activity, including respiratory center activity, causing breathing difficulties, headaches, dizziness, and even coma, leading to carbon dioxide anesthesia.

Composition of a complete animal anesthesia and euthanasia workstation

1. The equipment can meet the euthanasia and shallow anesthesia needs of small animals such as rodents, experimental rabbits, and cats

2. Working gas: carbon dioxide

3. The equipment is equipped with dual air supply, which can control the intake volume separately in separate channels

4. Multiple working hours and modes can be set and stored according to different animal species

5. Carbon dioxide controller: Range: 0-100% LEL, accuracy: 1% FS, response time ≤ 30S, can directly control the oxygen and carbon dioxide concentrations in the experimental box, automatically proportioning gas according to the set gas concentration, and maintaining a constant oxygen concentration environment. No need to mix proportional gases outside the box to ensure accurate experimental oxygen/CO2 concentration and save gas sources

6. Temperature display function monitoring parameters: temperature, humidity, oxygen O2 concentration, carbon dioxide concentration, low-temperature cycling function

7. The device has a built-in flow sensing module, which digitally displays the carbon dioxide inflation value

8. It has a reminder function when the work is completed

9. Equipped with danger alarm prompt function and carbon dioxide concentration exceeding limit reminder function

10. The device has one click operation function, personalized setting operation function, and internal cavity ultraviolet sterilization function

11. The equipment has exhaust gas recovery function

12. The operation screen is intelligent touch control
