Description

[Detailed description of the invention] "Industrial Application Field" The present invention relates to an anesthesia device for small animals such as pigs and sheep.

``Prior Art'' Conventionally, this type of anesthesia device is the one shown in Figure 6 of Japanese Patent Application Laid-open No. 194652/1983, which was previously proposed by the applicant of the present application, or the one shown in Figure 6 of the Buteyna, Denmark.
No. 1 of JP-A-63-263039 proposed by E/S
The item shown in the figure was found.

However, in the former anesthesia device, one movable safety side plate has a pair of movable safety side plates so that the small animal fixedly supported on the left and right retention side plates falls onto the receiving table installed at the outlet of the gas tank. An animal restrainer is used which is permanently locked by an engaging piece pivotally supported on the end plate. On the other hand, the latter anesthesia device has a pair of front and rear end plates 1 as shown in FIG.
, a box-shaped support 2 rotatably supported in these end plates, and a first side wall 3 supported between a pair of end plates, and the support 2 is connected to a bottom body. 2a and a second side wall 2b facing the first side wall 3, and the first side wall 3 has rail portions 3a at both ends thereof for guiding a protruding pulley 4 provided above the open end of the support body 2. I am using 5.

However, in the applicant's above-mentioned animal restraint device, the movable retention side plate rotates outward from the lower edge, so that the small animal falls onto the receiving table from the feet, the back, or the flank. As a result, the position of the feet was not fixed in a specific place, and the next process of shuckling was troublesome.

On the other hand, in the gondola 5 of Buteina, when the gondola 5 moves to the outlet of the gas tank, the engaging pulley of the support 2 provided inside the protruding pulley 4 engages with the guide means 6 provided in the gas tank. At the same time, the support body 2 rotates, and the small animal slides down to the receiving table through the resulting impulse gap 7. However, when there is only one small animal, if the balance is lost during transportation, the support body 2 will rotate. Since there is a possibility of the gondola tilting, two gondolas must be carried at all times, and since the support body 2 and the first side wall 3 are separate, assembly of the gondola is troublesome and, as a result, expensive.
Furthermore, the gondolas 5 cannot reliably support small and medium-sized animals being transported, and in addition, this type of anesthesia device uses multiple gondolas 5 in one unit, so the gondolas are expensive and the anesthesia device itself is very expensive. It had drawbacks such as being expensive.

``Purpose of the present invention'' In view of the above-mentioned shortcomings of conventional anesthesia equipment, the present invention has been developed to facilitate the shuckling operation in the next process, and to ensure that even one small animal to be transported can be securely held at the exit of the gas tank. It is easy to assemble and can be manufactured at low cost.Furthermore, the retaining side plate of the animal restrainer can be rotated reliably at the outlet of the gas tank.
To obtain a small animal anesthesia device which can prevent the retention side plate from rotating more than necessary and can also automatically return the holder of the animal restraint device.

"Means for Achieving the Object of the Present Invention" The small animal anesthesia device of the present invention comprises a holder having a U-shaped end face and a rotating body on the outer wall side of the retention side plate, and a connection between the holder and the holder. A plurality of animal restrainers each consisting of front and rear end plates that pivotally support one end of the plate are provided in a gas tank, and an outlet of the gas tank engages with the rotating body of the animal restraint moving upward. The present invention is characterized in that a guide member is fixedly provided, and a locking member is fixedly provided to stop the holder rotating toward the receiving table at a desired position by engagement and guidance of the guide member.

Figures 7 and 9 illustrate the operating mode of the invention. First, when a small animal M to be anesthetized enters the gas tank 13 from the inlet 12, the small animal M is once supported by the support plate 17a of the support device 17 within the animal restrainer Y. Next, when the working rod of the support device 17 contracts, the support plate 17a rotates downward. As a result, the small animal M descends a little, and both legs of the small animal M slightly protrude from the opening 36 of the holding body 26 that does not have a bottom plate, and the small animal M moves down the left and right holding side plates 28, 28.
Fixedly supported by A. The animal restrainer Y intermittently circulates within the gas tank 13 while supporting the small animal M with the left and right retaining side plates 28, 28A.

However, as shown in FIG.
Each rotating body 27, 2 of the holding body 26 as it rises
7A is slidably engaged with the guide member 18 of the mounting plate 20, and the holder 26 supports the end plates 21, 2 with its axis as a fulcrum.
Rotate to the outside of 1A. The rotation of the animal restrainer Y is stopped when the upper end of the retaining side plate 28A engages with the locking arm 19a of the locking member 19, as shown in FIG. At this time, the small animal M in the holding body 26 is
As shown in the figure, receive the table T from the back.
is sliding down. Then, when the animal restrainer Y starts to descend, the retainer 26 moves its pulleys 34, 34
rolls on the guide plate 37 for returning the holding body and rotates in the direction within the end face plates 21, 21A as shown in FIG. It gradually separates from the stop arm 19a and finally returns to its original state.

"Effects of the Invention" As is clear from the above explanation, the present invention has the following effects.

(1) The holder of the animal restraint device rotates from its upper end toward the outside of the end plate, so that the small animal held in the holder falls backward onto the receiving table.

Therefore, the position of the small animal's feet on the receiving table is always fixed, and the shuckling operation in the next step is facilitated.

(2) Animal restraint devices are capable of transporting small animals while securely holding them.

(3) Since the structure of the animal restraint device is simple, it is easy to assemble, and therefore each animal restraint device can be manufactured at low cost.

Therefore, anesthesia equipment can be installed at low cost.

(4) The holder of the animal restraint device can be reliably automatically rotated by the guide member 18 at the outlet of the gas tank.

(5) The rotation angle of the holder of the animal restraint device can be regulated by the locking member 19 so that the holder of the animal restraint device does not rotate more than necessary at the outlet of the gas tank.

(6) The holder can be automatically returned to the end plate as the animal restrainer moves up and down.

(7) The holder of the animal restraint device is safe because it does not rotate unexpectedly during transportation of small animals.
