Embodiment 1

[0023] Embodiment 1: The appearance of the breathing anesthesia mask for large animals is as follows: figure 1 As shown, its internal structure is as follows image 3 As shown, a manual radial compression device is provided inside the housing 1 .

[0024] see image 3 , Figure 4 with Figure 5 , the manual radial compression device includes six conical pressing pieces 6 that are evenly distributed on the inner side wall of the outer cover 1 and keep intervals with each other. 1 is located in the back area of ​​the conical pressure sheet to be provided with a support and a pin shaft 11 is installed in the support 15, each pin shaft 11 is hinged with a driving rod 5, and the inner end of each driving rod 5 is respectively hinged on the corresponding conical Press the back of the tablet 6. Ring spring 14 is connected between each driving lever 5, when stirring any driving lever 5 or stirring ring spring 14, can drive all driving levers 5 to move together, thereby drives eac...

Embodiment 2

[0029] Embodiment 2: On the basis of Embodiment 1, a plurality of uniformly distributed conical pressing pieces and driving rods are arranged. In order to make the driving rods swing synchronously for easy operation, radial sliding sleeves are respectively set on each driving rod, and each radial sliding sleeve is fixed on a connecting ring. Toggling the connecting ring can simultaneously drive a plurality of levers to swing synchronously.

Abstract

The invention discloses a large animal inhalational anaesthetic mask. A manual radial compression device is arranged at the inner side of a housing, and the large animal inhalational anaesthetic mask comprises at least two tapered pressers which are uniformly distributed on the inner side wall of the housing, a gap is formed between at least two tapered pressers, the tapered pressers are combined to form a combined conical structure with a small inner diameter and a large outer diameter, the areas, located at the back surface of the tapered pressers, on the housing is provided with supporting seats, a pin shaft is installed in each supporting seat, each pin shaft is hinged to a shifting rod, and the near inner end of each shifting rod is respectively hinged to the back surface of the corresponding tapered presser. A plurality of tapered pressers are combined to form a conical structure with small inner diameter and large outer diameter, so that the head part of a large animal can be easily inserted into the combined cone under the off-guard situation and is difficult to withdraw. All tapered pressers can be controlled to move inwards along the radial direction and along the axial direction by virtue of the shifting rods, so that a purpose for uniformly extruding and inwards pushing the head part of the animal can be achieved, and the effect is high and good. The operation is convenient.

Description

technical field [0001] The invention relates to the field of anesthesia devices for animal experiments, in particular to a breathing anesthesia mask for large animals. Background technique [0002] At present, in the process of pharmaceutical experiments, large animals such as ferrets or chinchillas are used as experimental subjects, and blood collection and other treatments need to be performed in a quiet situation, which requires anesthesia of the large animals before treatment. Ether inhalation anesthesia is a commonly used anesthesia method. Due to the large size of large animals, it will cause a lot of trouble if the animals do not cooperate. The common operation is to cover the mouth and nose of large animals with cotton balls containing ether, and perform re-anesthesia. However, when this method is anesthetized, the cotton ball containing ether is exposed to the air, and the ether is easy to volatilize, which greatly affects the health and safety of the experimenters....
