Dose-adjustable inhalation continuous anesthesia device for small and medium-sized animals

Abstract

The invention discloses a dose-adjustable inhalation continuous anesthesia device for small and medium-sized animals, and belongs to the technical field of animal anesthesia. The anesthesia device comprises a double-ball air supply device, an anesthetic gasification device, an anesthetic supplement device, an anesthesia tube, a fixing device, and an anesthetic exhaust gas absorption device. The double-ball air supply device, the anesthetic supplement device and the anesthesia tube are all connected with the anesthetic gasification device. The anesthesia tube has a transparent valve. The transparent valve allows a front leg of a small and medium-sized animal to enter the anesthesia tube without being easily withdrawn. The anesthetic gasification device is provided with an anesthetic and a non-volatile liquid which is miscible with the anesthetic. By controlling the concentration of anesthetic gas entering the anesthesia tube, the animal is kept under anesthesia by continuously inhalingthe anesthetic gas within a certain concentration range, so that the animal can be kept anesthetized during an experiment, and is not over- or too lightly anesthetized, so that the experiment can be carried out better. The anesthesia device is simple to manufacture, convenient to operate, economical and practical, and convenient for popularization and application.

Description

technical field [0001] The invention relates to an inhalation-type continuous anesthesia device for small and medium-sized animals with adjustable dosage, and belongs to the technical field of animal anesthesia. Background technique [0002] Inhalation anesthesia is a common way of anesthesizing small and medium-sized animals in the laboratory. Anesthesia is not only to reduce the pain and discomfort of animals, but also to ensure the smooth progress of operations and experimental research. The maintenance of anesthesia and the control of anesthesia depth are of great importance to the experiment. Success is crucial. Too light anesthesia can cause animal restlessness to affect the operation, and too deep anesthesia can cause respiratory depression or even death. Conventional simple methods are difficult to control the depth of anesthesia. In addition, most anesthesia devices cannot directly induce anesthesia, and surgery is performed while anesthesia is performed; and during...

Problems solved by technology

[0002] Inhalation anesthesia is a common way of anesthesizing small and medium-sized animals in the laboratory. Anesthesia is not only to reduce the pain and discomfort of animals, but also to ensure the smooth progress of operations and experimental research. The maintenance of anesthesia and the control of anesthesia depth are of great importance to the experiment. Success is very important. Too light anesthesia will cause animal restlessness to affect operation, and too deep anesthesia will cause respiratory depression or even death of animals. Conventional simple methods are difficult to control the depth of anesthesia

In addition, most anesthesia devices cannot directly induce anesthesia, and the operation is performed while anesthesia; and during the experiment, due to the insufficient airtightness of the anesthesia device, the anesthesia waste gas leaks, endangering the health of the experimental operators and polluting the environment

However, the price of commercially available special anesthesia machines for small animals is about 10,000 to 20,000 yuan, plus supporting equipment and consumables, etc., resulting in high cost requirements. Therefore, an economical, safe and effective animal anesthesia laboratory device is needed to solve this problem. question

[0003] Application number: CN201621395174.3 (mice anesthesia device for experiments) anesthetizes mice by spraying ether reagent in a spray bottle. Although it is airtight to prevent gas leakage, it cannot achieve continuous anesthesia, so it cannot guarantee a long time-consuming process. Complicated experimental operations are carried out smoothly

[0004] Application number: CN201420184897.3 (an ether anesthesia hood for rats) During the experimental operation on rats, when the rats begin to appear awake symptoms, the device must be buckled on the head of the rats to repeat anesthesia, and the dose can not be adjusted continuous anesthesia

[0005] Application number: CN201020615224.0 (continuous inhalation anesthesia device for rat surgery), the anesthesia cylinder is a 50ml medical syringe, the airtightness is not good enough, the anesthesia waste gas will leak, pollute the environment, and endanger the health of operators
