Description

Technical Field

[0001] The utility model relates to the technical field of anesthesia equipment, in particular to an anesthesia device for animal experiments. Background Art

[0002] In modern biomedical research, animal experiments are an essential and indispensable part. When conducting animal experiments, in order to ensure the smooth progress of the experiments and reduce the pain of animals, effective anesthesia of animals is crucial.

[0003] Traditional animal anesthesia methods often have many deficiencies. Some simple anesthesia means may not be able to accurately control the dosage and concentration of anesthetic agents, resulting in unstable anesthesia effects. Animals may wake up prematurely or be over-anesthetized during the experiment, affecting the accuracy and reliability of experimental data. In addition, traditional anesthesia devices also have defects in gas delivery and recovery. The uneven distribution of gas may lead to insufficient anesthesia in some areas, while the lack of an effective recovery mechanism may cause waste of anesthetic agents and environmental pollution. Based on this, we designed a device with a simple structure and capable of controlling the dosage and concentration of anesthetic agents, thereby improving the stability of anesthesia. Summary of the Utility Model

[0004] Aiming at the technical problems existing in the background art, the utility model provides an anesthesia device for animal experiments, which not only has a simple structure, but also can control the dosage and concentration of anesthetic agents, and is convenient for operators to use.

[0005] The technical implementation scheme of the utility model is: an anesthesia device for animal experiments, including a gas guiding mechanism, an anesthesia mechanism and a recovery group. The gas guiding mechanism is connected to the anesthesia mechanism through a first gas guiding pipeline, and the anesthesia mechanism is connected to the recovery group through a second gas guiding pipeline to form a connected state; the gas guiding mechanism includes a fourth connection groove, an air pump, a first flowmeter, a second flowmeter, an anesthetic agent bottle and a first control valve.

Specific embodiments

[0026] To make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings. It is hereby declared that the terms of orientation such as up, down, left, right, front, back, inside and outside that appear or will appear in the text of the present utility model are only based on the accompanying drawings of the present utility model, and they do not specifically limit the present utility model.

[0027] As Figures 1-7As shown in the figure, an animal experiment anesthesia device includes an air guiding mechanism 4, an anesthesia mechanism 6 and a recovery group 5. The air guiding mechanism 4 is connected to the anesthesia mechanism 6 through a first air guiding pipeline 17, and the anesthesia mechanism 6 is connected to the recovery group 5 through a second air guiding pipeline 11 to form a connected state. The air guiding mechanism 4 includes a fourth connection groove 401, an air pump 402, a first flowmeter 405, a second flowmeter 409, an anesthetic bottle 407 and a first control valve 411. The air pump 402 is arranged inside the fourth connection groove 401. The air pump 402 is connected to the anesthetic bottle 407 through a third air guiding pipe 403 and a first flowmeter 405, thereby forming a first air guiding channel. The air pump 402 is connected to the first control valve 411 on a fourth air guiding pipeline 412 through a fifth air guiding pipeline 408 and a second flowmeter 409, thereby constituting a second air guiding channel. The anesthetic bottle 407 is connected to the anesthesia mechanism 6 through the fourth air guiding pipeline 412. The anesthesia mechanism 6 includes an anesthesia box 601, a sealing cover 602 and an opening and closing plate 605. The sealing cover 602 is arranged at the opening of the anesthesia box 601.

[0028] It should be noted that during animal experiments, animals need to be anesthetized first. Existing anesthesia equipment generally mixes oxygen and anesthetic and then introduces it into the anesthesia box. However, the whole structure is relatively complex, the mixing concentration of oxygen and anesthetic cannot be controlled, and it cannot be recycled and purified, which affects the use. Based on this, we designed an anesthesia device that is convenient for gas mixing and can be recycled.

[0029] It should be further noted that in order to realize the mixed introduction of anesthetic, we designed the air guiding mechanism 4, the anesthesia mechanism 6 and the recovery group 5. Moreover, the air guiding mechanism 4 is connected to the anesthesia mechanism 6. In order to mix air and anesthetic, we designed an air pump 402 inside the fourth connection groove 401. Under its operation, air is introduced into the anesthetic bottle 407, bringing out the internal anesthetic, and is connected to the anesthesia mechanism 6 through the fourth air guiding pipeline 412 to realize the first air guiding.

[0030] It should be further noted that in order to control and improve the mixing efficiency, we designed a second air guiding channel. The air pump 402 is connected to the first control valve 411 on the fourth air guiding pipeline 412 through a fifth air guiding pipeline 408 and a second flowmeter 409 to realize the second air guiding and introduce air into the first control valve 411, which can be opened and closed according to needs, improving the convenience of the equipment.

[0031] Such as Figures 1-5As shown, a three-way valve 415 is provided on the fourth air guide pipe 412. The three-way valve 415 is connected to the air inlet of the anesthesia mask 10 and the anesthesia box 601 through a sixth air guide pipe 416 and a seventh air guide pipe 417 respectively. The first flowmeter 405 is connected to the anesthetic bottle 407 through an eighth air guide pipe 406. The second flowmeter 409 and the first control valve 411 are connected through a ninth air guide pipe 410.

[0032] It should be noted that in order to control the imported dosage, we designed the first flowmeter 405 and the second flowmeter 409 to control the air imported into the anesthetic bottle 407 and the air inside the fourth air guide pipe 412 respectively, which is convenient for control.

[0033] As Figures 1-6 shown, the anesthesia box 601 is a rectangular cavity structure with an open upper part. An air inlet and an air outlet are provided on the anesthesia box 601. The air outlet of the anesthesia box 601 is connected to the recovery group 5 through a second air guide pipe 11. An observation window 603 and an opening and closing plate 605 are provided on the sealing cover 602. The opening and closing plate 605 is movably arranged on the rectangular opening 604 of the sealing cover 602. An air vent 606 and a sealing plug 607 are provided on the opening and closing plate 605.

[0034] It should be noted that for the convenience of animal anesthesia operation, our anesthesia box 601 is a rectangular cavity structure with an open upper part, and a sealing cover 602 is provided on the anesthesia box 601. An opening and closing plate 605 is provided on the rectangular opening 604 of the sealing cover 602, which is convenient for the staff to take and increases air permeability.

[0035] As Figure 1 and Figure 7 shown, the recovery group 5 includes a gas recovery tank 501 and a purification box 503. The air outlet of the gas recovery tank 501 is connected to the purification box 503 through a tenth air guide pipe 502. The purification box 503 is connected to the fourth connection groove 401 through a limiting block.

[0036] It should be noted that in order to recover the gas containing anesthetic, we designed a recovery group 5, which includes a recovery tank 501 and a purification box 503. Among them, the recovery tank 501 is connected to the air outlet of the anesthesia box 601 through a second air guide pipe 11. The activated carbon inside the recovery tank 501 can adsorb the anesthetic to prevent pollution to the outside.

[0037] It should be further noted that for the convenience of purification, we also designed a purification box 503. The purification box 503 is connected to the air outlet of the gas recovery tank 501 through a tenth air guide pipe 502, which can purify the used anesthetic gas again. A purification liquid is provided inside the gas recovery tank 501 to facilitate full contact with the anesthetic gas.

[0038] As Figures 1-7 shown, the air guiding mechanism 4 is arranged in the first connecting groove 9 of the fixed bracket 1, the anesthetic mechanism 6 is arranged in the second connecting groove 3 of the fixed bracket 1; the recovery group 5 is arranged in the third connecting groove 2 of the fixed bracket 1; connecting brackets 12 are arranged on both sides of the fixed bracket 1, and a push rod 13 is arranged in the middle of the two connecting brackets 12, and a flexible rubber sleeve 14 is arranged on the push rod 13; a plurality of runners 8 are arranged at the bottom of the fixed bracket 1.

[0039] It should be noted that, for the convenience of handling the whole mechanism, we centrally designed the air guiding mechanism 4, the anesthetic mechanism 6 and the recovery group 5 on the fixed bracket 1, and a push rod 13 is designed on the fixed bracket 1 to facilitate the operator to push.

[0040] The embodiments of the present utility model have been described in detail above in conjunction with the accompanying drawings. However, the present utility model is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present utility model within the scope of knowledge possessed by those skilled in the art.
