Embodiment

[0025] Example: The appearance of the small animal breathing anesthesia mask is as follows: figure 1 As shown, its internal structure is as image 3 As shown, a manual radial compression device is provided inside the housing 1 .

[0026] see image 3 , Figure 4 and Figure 5 The manual radial compression device includes two radial pressure plates 11 that are evenly distributed on the inner side wall of the outer cover 1 and keep a distance from each other. The back of each radial pressure plate 11 is provided with a guide rod 12 that passes through the through hole on the side wall of the outer cover 1, and A spring 13 supported on the outer surface of the outer cover 1 is sleeved at the end of the guide rod 12, and a block is provided at the end of the guide rod 12 to prevent the spring 13 from falling off.

[0027] Simultaneously, on the cover 1, a support 17 is arranged on the back area of ​​the radial pressure plate 11 and a pin shaft 15 is installed in the support 17...

Embodiment 2

[0032] Example 2: see Figure 6 , On the basis of Embodiment 1, a plurality of evenly distributed radial pressure plates 11 and swing rods are set. In order to make the swing rods swing synchronously for easy operation, radial sliding sleeves 18 are respectively sleeved on each swing rod, and each radial sliding sleeve 18 is fixed on a connecting ring 19 . Toggling the connecting ring 19 can simultaneously drive a plurality of swing bars to swing synchronously.

Embodiment 3

[0033] Embodiment 3: An improvement is made on the basis of Embodiment 2, that is, ring springs 13 are connected between each swing rod. Toggling the ring spring 13 can simultaneously drive a plurality of swing bars to swing synchronously. At this time, the connecting ring 19 and the radial sliding sleeve 18 are not provided.

Abstract

The invention discloses a small animal respiratory anaesthetic mask which comprises an outer cover, a gas inlet pipe, a gas return pipe and an anaesthetic gas source. A manual radial compression device is arranged on the inner side of the outer cover and comprises at least two radial pressing plates which are evenly distributed on the inner side wall of the outer cover and are spaced, a guide rod penetrating through a through hole in the side wall of the outer cover is arranged on the back face of each radial press plate, and a spring supported on the outer surface of the outer cover is arranged at the tail end of each guide rod in a sleeving mode. The multiple radial pressing plates are adopted in the small animal respiratory anaesthetic mask, the pressing plates can be controlled to move inwards in the radial direction through swing rods, and traumas caused by the anaesthetic work cannot be brought to small hamsters. By means of the mask and an inlet in the mask, the size of the inlet can be automatically adjusted according to the body type of small animals to ensure that anaesthetic gas is not leaked at all, and the risk that clinical workers inhale the anaesthetic gas is avoided. The small animal respiratory anaesthetic mask is reasonable in structural design, good in use effect and suitable for application and popularization in the small animal anaesthetic field.

Description

technical field [0001] The invention relates to the field of anesthesia devices for animal experiments, in particular to a breathing anesthesia mask for small animals. Background technique [0002] The anesthesia of experimental mice is a link in the in vivo experiment and effectiveness evaluation of medicines in the process of medicine research and development. However, due to the small size of small hamsters, there is no dedicated anesthesia device for volatile anesthetics such as ether / isofluorane. Usually, simple anesthesia devices are made by filling cotton in beakers and specimen jars, but a large amount of volatile anesthetics volatilizes, which is harmful to the health of the operator It will cause an impact and waste anesthetics; moreover, the anesthesia dose and depth of anesthesia are not easy to control; volatile anesthetics also have the characteristics of rapid anesthesia and rapid recovery, and the operation is time-consuming when the mice are taken out, which...
