Embodiment 1

[0023] Example 1: The appearance of the large animal respiratory anesthesia mask is as follows figure 1 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 and 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 a distance from each other. 1 is provided with a support in the back area of ​​the conical pressing piece, and a pin shaft 11 is installed in the support 15. Each pin shaft 11 is hinged with a lever 5, and the inner end of each lever 5 is hinged on the corresponding cone. Sheet 6 back. A ring spring 14 is connected between the levers 5. When any lever 5 or the ring spring 14 is toggled, all the levers 5 can be driven to move together, thereby driving the conical pressing pieces 6 to move together.

[0025] The combined cone-shaped stru...

Embodiment 2

[0029] Example 2: On the basis of Example 1, a plurality of uniformly distributed conical pressing sheets and levers were provided. In order to make the levers swing synchronously and facilitate the operation, radial sliding sleeves are respectively sleeved on each lever, and each radial sliding sleeve is fixed on a connecting ring. The toggle connecting ring can simultaneously drive a plurality of toggle 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 respiratory 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 objects, which need to be treated such as blood sampling in a quiet condition, which requires anesthesia of the large animals before the treatment. Ether inhalation anesthesia is a commonly used anesthesia method. Due to the large size of large animals, it will bring a lot of trouble if the animals do not cooperate. The common operation is to cover the mouth and nose of the large animal with a cotton ball containing ether to perform re-anesthesia. However, when the cotton ball containing ether is exposed to the air during anesthesia with this method, the ether is volatile, which greatly affects the health and safety of the experimenters. Therefore, it ...
