Description

Inhalation type anaesthetic mask for animals

Technical Field

The utility model relates to the technical field of anesthesia equipment, in particular to an inhalation type anesthesia mask for animals.

Background

In the medical animal experiment, veterinary medicine and pet medical industry, animals are often subjected to anesthesia treatment. The current methods of anesthesia for animals are mainly injection anesthesia and inhalation anesthesia. Injection anesthesia is a method of administering anesthesia by injecting an anesthetic intravenously, intramuscularly, or intraperitoneally to bring an animal into an anesthetic state. Injection type anesthesia is relatively strict in control of the dosage of anesthesia, the operation difficulty is relatively high, the condition that animals die due to poor anesthesia effect or excessive anesthesia often occurs, the anesthesia medicine can be cleared in vivo after being metabolized by the liver and the kidney, certain side effects are caused to the liver and the kidney, the result of an animal experiment is influenced, and the awakening time of the anesthetized animals is relatively long. When the inhalation anesthesia is used, the anesthesia medicine enters the alveolus through breathing and then enters the blood, the concentration of the anesthesia medicine in the blood and the inhalation concentration reach the balance to maintain the anesthesia state, after the inhalation of the anesthesia medicine is stopped, the anesthesia medicine in the blood is exhaled out of the body through the alveolus, the anesthesia medicine is basically not needed to be metabolized in the body, the anesthesia medicine is cleared quickly, the damage to the internal organs is small, the influence on the experimental result is small, the awakening time of the respiration anesthesia is short, as long as the inhalation of the anesthesia gas is stopped, the animal can awaken in a short time, the dosage of the medicine is easy to control, and the anesthesia effect is good. From the effect of practical application, although inhalation anesthesia is relatively safe, a certain amount of anesthetic gas must be continuously kept to be inhaled, and at present, no portable animal anesthesia device which is convenient to wear and suitable for being used under the conditions of CT and nuclear magnetic resonance exists, so that the requirement of carrying out inhalation anesthesia on animals in places such as laboratories, pet hospitals, fields, medical imaging rooms and the like cannot be met.

As shown in fig. 1-3, an inhalation type anaesthetic mask for animals comprises a mask body 1, an air outlet nozzle 2, an air inlet nozzle 3 and a fixing piece. The cover body 1 is used for covering the mouth and nose parts of animals, generally, the edge of the cover body 1 is consistent with the outline of the face of the animals as much as possible, a leather sheath and the like can be arranged at the edge, and the external air is prevented from entering the cover body 1 from the edge of the cover body 1 as much as possible. The air outlet nozzle 2 is communicated with the cover body 1 and is communicated with a waste gas filtering device (not shown in the figure) through an air guide hose (not shown in the figure), and the air exhaled by the animal and the redundant anesthetic gas which is not inhaled by the animal are guided into the waste gas filtering device through the air outlet nozzle 2 and the air guide hose to be processed and then discharged. The air inlet nozzle 3 is communicated with the cover body 1 and is connected with an air delivery hose (not shown in the figure) for delivering anesthetic gas of an anesthesia machine (not shown in the figure), and the anesthetic gas with certain concentration generated by the anesthesia machine enters a closed space between the cover body 1 and the mouth and nose parts of the animals through the air delivery hose and the air inlet nozzle 3. The fixing piece is a device or a rope belt for fixing the cover body 1 on the mouth and nose of an animal, so that the edge of the cover body 1 is sealed (not absolutely sealed) with the periphery of the mouth and nose of the animal.

The cover body 1 can be covered on the mouth and nose parts of the animals through the fixing piece, a relatively closed space is formed in the mouth and nose parts of the animals, anesthetic gas is introduced through the air inlet nozzle 3 to carry out inhalation anesthesia on the animals, and gas exhaled by the animals and non-inhaled anesthetic gas are led out through the air outlet nozzle 2, so that the wearable animal inhalation anesthesia device is provided. When the anesthesia mask is actually used, in order to eliminate the influence on the operation process caused by the biting and scratching of the animal when the animal is awake, induction anesthesia is firstly carried out, the induction anesthesia is completed when the animal is in an anesthesia state, and the animal is taken out from the induction anesthesia device, so that the anesthesia mask can be worn.

In this embodiment, a one-way valve (not shown) is also provided, for example: a one-way valve is arranged between the air outlet nozzle 2 and the cover body 1, and the air flowing direction of the one-way valve is from the cover body 1 to the air outlet nozzle 2; or a one-way valve is arranged between the air outlet nozzle 2 and the air guide hose, and the air flowing direction of the one-way valve is from the air outlet nozzle 2 to the air guide hose. Through setting up the check valve, guarantee that the gas that the animal inhales is the anesthetic gas of anesthesia machine supply, avoid the animal to reduce the anesthesia effect because of inhaling the gas that flows backwards from gas outlet nozzle 2.

Optionally, referring to fig. 2, the air intake nozzle 3 is movably and hermetically disposed at one side of the cover body 1, the fixing member includes a trip 4, a pre-compressed spring 5 and an annular latch device 6 for hooking on the animal teeth, the trip 4 is fixedly sleeved at one side of the air intake nozzle 3 located outside the cover body 1, the spring 5 is sleeved on the air intake nozzle 3, the spring 5 is pre-compressed between the trip 4 and the cover body 1, the latch device 6 is located in the cover body 1, and the latch device 6 is connected with one end of the air intake nozzle 3 located in the cover body 1. Taking an anaesthetic mask suitable for rodents as an example, the rodents are characterized in that the upper jaw and the lower jaw are respectively provided with two upper incisors 8 and lower incisors 9 which can continuously grow, and the upper incisors and the lower incisors are bent towards opposite directions in a sickle shape. By utilizing the characteristic of the rodent incisors, the respirator can be fixed on the incisors. The gear hanging device 6 is arranged inside the cover body 1 and connected with the air inlet nozzle 3 extending into the cover body 1 through a hole, the air inlet nozzle 3 is sleeved with a spring 5 with prepressing force outside the cover body 1, the spring 5 is clamped by the clamping tenon 4, the spring 5 enables the gear hanging device 6 to generate a pulling force to press the air inlet nozzle 3 towards the cover body 1, the gear hanging device 6 extends out of the cover body 1, the upper incisor 8 of a mouse extends into the biting hole 7 of the gear hanging device 6 to release the pressing force of the air inlet nozzle 3, the spring 5 provides a pushing force for the cover body 1, and the pushing force tightly buckles the cover body 1 on the mouth and nose of the mouse, so that the cover body 1 is fixed.

Alternatively, referring to fig. 3, the securing member is an elastic band, lace, or tape. For example: the elastic band is divided into two parts, one part is a neck elastic band 10 which is wound around the neck of the mouse, the other part is a connecting elastic band 11, one end of the connecting elastic band is arranged on the cover body 1, the other end of the connecting elastic band is connected with the neck elastic band 10, a plurality of connecting elastic bands 11 are connected with the neck elastic band 10, and the cover body 1 is fixed on the mouth and nose part of the mouse by using the neck elastic band 10 as a fixing point and using elasticity.

The anesthetic gas enters the cover body 1 from the air inlet nozzle 3 along the direction, the exhaled gas and the non-inhaled anesthetic gas are discharged from the air outlet nozzle 2, and the exhausted gas passes through the one-way valve. In a preferred embodiment, the mouthpiece 3 is directed towards the mouth and nose of the rat, so as to inhale directly the anesthetic gas entering from the mouthpiece 3.
