Description
Technical field
The present invention relates to zooperal anesthesia outfit field, particularly relate to a kind of big animal breath anaesthetic mask.
Background technology
At present, during pharmaceutical test, with big animal such as ferret or dragon cat as experimental subjects, need its quietly in the case of carry out taking blood etc. and process, this is accomplished by anaesthetizing big animal before treatment.Ether inhalation anesthesia is a kind of conventional anesthesia, and owing to big animal volume is relatively big, animal is mismatched and can bring a lot of trouble, and common operation is to cover big animal mouth and nose with the cotton balls containing ether, carries out and again anaesthetizes.But during this kind of method anesthesia, the cotton balls containing ether exposes in atmosphere, and ether is volatile, and extreme influence experimenter's is healthy and safe.Therefore, find a kind of can realize in big zoopery safety continuous anesthesia experimental apparatus the most necessary.
When being anaesthetized by anesthesia aid, usual animal mismatches this anesthesia, if aid design is unreasonable, animal can be caused to fix insecure, extends anesthesia duration, causes animal resistance even to hurt sb.'s feelings.
It addition, existing big Animal Anesthesia instrument arranges outer cover and is installed into tracheae and muffler, but the gas majority of air inlet pipe is directly entered muffler, causes anesthesia gas concentration inside outer cover the highest, and anesthesia efficiency is low.Existing anesthesia aid cannot ensure effective anesthesia duration, it is difficult to controls anesthesia level.The short big animal of anesthesia duration easily revives during taking blood, affects experimental implementation and even injures experimenter.But, ether dosage is crossed conference and is caused big animal physiological index to change even death, affects experimental result, wastes anesthetic simultaneously.
Summary of the invention
For lacking suitable and safe big Animal Anesthesia instrument problem in prior art, the present invention provides a kind of easy to operate, safety, the big animal breath anaesthetic mask that using effect is good.
The present invention solves the scheme that its technical problem used: a kind of big animal breath anaesthetic mask, including outer cover, air inlet pipe and muffler, and anesthesia source of the gas, manual radial compression device it is provided with inside outer cover, manual radial compression device includes that at least two is distributed on outer cover madial wall and retains the taper compressing tablet at interval each other, each taper compressing tablet is combined into the combination cone shape structure that internal diameter is little and external diameter is big, it is provided with bearing in taper compressing tablet rear surface regions and bearing pin is installed in bearing outer cover is upper, it is hinged with driving lever on each bearing pin, the inner end of each driving lever is respectively hinged at the corresponding taper compressing tablet back side.
Each taper compressing tablet inner surface is provided with anti-slip veins or point-like is protruding.
Between described each taper compressing tablet, and it is sealed with between each taper compressing tablet and outer cover inwall and is connected cloth.
Connect between each driving lever and have ring spring.Or, each driving lever is respectively installed with radially sliding sleeve, each radially sliding sleeve is fixed on one and connects on ring.
Described outer cover inner ring is provided with return-air chamber, and return-air cavity wall is uniformly distributed along the circumference and is provided with air cleft, and air cleft is communicated in air inlet pipe and return-air chamber；Return-air chamber lateral wall is provided with gas outlet and connects with described muffler.
The medial surface of described each taper compressing tablet is each provided with one layer of elastic layer, elastic layer surface configuration skid resistant course.
The invention has the beneficial effects as follows:
1. the present invention uses multiple taper compressing tablet, it is combined into the combination cone shape structure that internal diameter is little and external diameter is big, big animal is facilitated to make its head can be readily intercalated in combination cone in the case of unguarded, taper compressing tablet can be promoted to contract due to head and each taper compressing tablet friction after insertion, this structure is that Yi Jinnan goes out structure.Again by driving lever can control to make each taper compressing tablet radially inward+move axially inward, thus reach uniformly to extrude and inwardly promote the purpose of fixture head, high efficiency fruit is the best.Uniformly extruding is possible to prevent animal head by additional injury.Elastic layer can also be set at each taper compressing tablet madial wall, so that it is guaranteed that wound will not be brought because of anesthesia work to animal head.
2. utilize return-air chamber and uniform multiple air clefts, it can be ensured that anesthetic gases is evenly distributed on the inner region of outer cover, reach the fastest optimal anaesthetic effect.
3. ring spring or connection ring may insure that each driving lever can synchronous hunting, conveniently operation.Its reasonable in design, using effect is good, is suitable in big Animal Anesthesia field popularization and application.

Detailed description of the invention
The present invention is further described with embodiment below in conjunction with the accompanying drawings.
Embodiment 1: the outward appearance of big animal breath anaesthetic mask is as it is shown in figure 1, its internal structure is as it is shown on figure 3, be provided with manual radial compression device inside outer cover 1.
See Fig. 3, Fig. 4 and Fig. 5, manual radial compression device includes that six are distributed on outer cover 1 madial wall and retain the taper compressing tablet 6 at interval each other, each taper compressing tablet 6 is combined into the combination cone shape structure that internal diameter is little and external diameter is big, outer cover 1 is positioned at taper compressing tablet rear surface regions be provided with bearing and at bearing 15, bearing pin 11 be installed, being hinged with driving lever 5 on each bearing pin 11, each inner end of driving lever 5 is respectively hinged at corresponding taper compressing tablet 6 back side.Connect between each driving lever 5 and have ring spring 14, when stirring arbitrary driving lever 5 or stirring ring spring 14, all driving levers 5 can be driven to move together, thus drive each taper compressing tablet 6 to move together.
Described internal diameter is little and combination cone shape structure that external diameter is big, facilitate big animal to make its head can be readily intercalated in combination cone in the case of unguarded, but more difficult exit voluntarily.Quickly stir driving lever 5 simultaneously, make each taper compressing tablet 6 move radially inward, axially simultaneously inward, thus reach uniformly to extrude and inwardly push away the purpose of animal head, high efficiency fruit is good.
See Fig. 4, in order to prevent the hole of outer cover 1 side or the gas leakage of bearing 15 position, between each taper compressing tablet 6, and be sealed with between each taper compressing tablet 6 with outer cover 1 inwall and be connected cloth 13.
In Fig. 3, in order to reach gas distribution effect the most evenly, prevent being directly entered muffler 3 from the gas of air inlet pipe 2 and be discharged, also outer cover 1 inner ring is provided with return-air chamber 9, return-air chamber 9 inwall is uniformly distributed along the circumference and is provided with air cleft 10, and air cleft 10 is communicated in air inlet pipe 2 and return-air chamber 9；Return-air chamber 9 lateral wall is provided with gas outlet and connects with described muffler 3.
Prevent from, because anesthesia causes big animal head to injure, one layer of elastic layer, elastic layer surface configuration skid resistant course to be each provided with at the medial surface of each taper compressing tablet 6.Directly each taper compressing tablet 6 inner surface can also be provided with anti-slip veins 8 or point-like projection.
Embodiment 2: on the basis of embodiment 1, arranges multiple uniform taper compressing tablet and driving lever.In order to make each driving lever synchronous hunting, it is simple to operation, each driving lever being respectively installed with radially sliding sleeve, each radially sliding sleeve is fixed on one and connects on ring.Stir connection ring and can drive multiple driving lever synchronous hunting simultaneously.
