Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention can be easily fixed in animal experiments using experimental animals, particularly rabbits and guinea pigs, and by exposing the back, the back is shaved and the skin is stimulated thereafter. The present invention relates to an animal immobilizer capable of easily conducting a sex test.

[0002]

2. Description of the Related Art When evaluating the safety of newly developed foods, cosmetics or drugs, tests using experimental animals are usually carried out. A skin irritation test is performed especially when evaluating the safety of cosmetics and ointments. Skin irritation tests are usually performed on the back of the animal with the highest percentage of body surface. At that time, the hair covering the body surface of the experimental animal interferes with the test, and thus the hair must be shaved as a preparatory step.

Conventionally, the hair-cutting work of experimental animals has been carried out mainly by a plurality of people. That is, one or several people pressed down the animal, and the other one cut the hair on the back of the animal with a clipper or the like. However, when an animal violently violently, this method requires a great deal of physical strength and skill to hold down the animal, and stress and a wound given to the animal are also serious problems.

As a countermeasure, use of a fixing device for animal experiments can be considered. For example, the fixing device disclosed in Japanese Patent Laid-Open No. 2000-197649 is a device for fixing an animal very firmly so that the restraint does not come off even if the animal violently undergoes manual treatment or the like. However, in that case, not only the work of fixing the rabbit becomes complicated and the work of fixing the rabbit becomes complicated, but also the rabbit's body surface, mainly a considerable part of the back side, is covered with the fixing portion.

On the contrary, when using a fixing device which is commercially available for animal transportation, veterinary care, shampooing and hairdressing at a pet beauty salon, there are few fixing parts, and the body surface is relatively small. Although relatively exposed, it is inconvenient because the restraint on the animal's body is weakened, and additional human or instrumental assistance is required.

[0006] In the skin irritation test of experimental animals, there has been no animal immobilizer that meets the requirement of immobilizing the animal reliably and simply by exposing the body surface to a large extent.

[0007]

DISCLOSURE OF THE INVENTION The present invention, when performing a skin irritation test using an experimental animal, allows easy and reliable fixation of the animal, and further exposes the back to remove hair from the back. An object is to provide an animal immobilizer that can be easily performed.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below. The animal fixing device of the present invention

FIG. 1 shows. The animal immobilizer of the present invention is composed of a lower base 1 and an upper base 2. The lower base 1 has the upper base 2 mounted thereon, and the neck fixture 3 existing at the front end thereof.
Has the function of fixing the neck of the animal. Neck fixture 3
Is mainly composed of two parts having a structure in which the central part is curved in a semicircular shape, and the upper and lower parts are combined to form a ring-shaped structure. The animal's neck is clamped from above and below via the upper hinge 4 and fixed.

On the other hand, the upper pedestal 2 has a function of mounting the body of a rabbit and stabilizing the abdomen and then fixing the waist. The upper base 2 is characterized in that the central surface 5 of the upper base is inclined upward toward the front. This has the effect of allowing the animal to assume a natural or comfortable posture, reducing the burden on the body, and having the effect of exposing the back greatly. The inclination angle is preferably in the range of 25 degrees to 35 degrees.

The upper table 2 can be slid back and forth so as to slide on the lower table 1 in parallel with the body axis of the animal. This allows adjustment according to the length of the animal. In that case, it is desirable to carry it while holding the handle 12.

The upper base 2 has a left guard plate 6 and a right guard plate 7 on a central surface 5 of the upper base, and a waist fixing tool 9 on a rear surface 8 of the upper base. The left and right guard plates 6 and 7 are located parallel to the head-to-tail direction of the animal, and have a function of suppressing the movement of the abdomen to the left and right while covering the abdomen and the side of the body of the animal. These guard plates are not particularly limited to a flat shape or a curved shape as long as they do not hinder the hair cutting of the back of the animal. The intersection angle between these guard plates and the central surface of the upper stand is 4
It is desirable to have an inverted C-shaped positional relationship when viewed from the front or the rear in the range of 5 to 50 degrees.

The waist fixing device 9 is fixed so as to cover the waist of the animal, particularly the part from the vicinity of the hip joint to the toes. The waist fixing device 9 is connected to the upper base by a lower hinge 10 and is characterized by being openable / closable vertically with respect to the head-tail direction of the animal. After closing the waist fixing device 9 so that the part from the waist to the toes of the animal is covered, the stopper 11 is tightened and fixed.
The stopper 11 is not particularly limited as long as it has a function of preventing the waist fixing tool 9 from reopening due to the movement of the body of the animal.

The material of the animal immobilizer of the present invention is not particularly limited as long as it can be easily processed and can withstand the work of mounting an animal. For example, stainless steel, aluminum, plastic, wood, or a plurality of combinations including these may be used. In addition, a cushion may be incorporated in a portion which comes into direct contact with the body of the animal upon fixation so as to reduce friction of the portion.

The animal to be fixed by the animal immobilizer of the present invention is not particularly limited, but rabbits and guinea pigs which are usually used for skin irritation test are preferable.

EXAMPLES Examples of the present invention will be described below, but the present invention is not limited to the following examples. In this example, Japanese white rabbit (Kbl: J
W, manufactured by Kitayama Labes Co., Ltd.) was fixed by the animal fixing device of the present invention, and then the hair was cut. (1) The neck fixing tool 3 of the lower table 1 was opened up and down, and the waist fixing tool 9 of the upper table 2 was opened left and right in advance. (2) A rabbit was placed on the upper table 2 in a crawling state, and then placed so that the abdomen of the rabbit was positioned between the left and right guard plates 6 and 7. (3) The rabbit neck was put in a ring-shaped portion located in the center of the neck fixture 3, and then the neck fixture 3 was closed by sandwiching the upper hinge 4 from above and below to fix the rabbit neck. . At that time, it is desirable to fix the front legs so that they are brought forward. (4) Lightly pull both hind legs of the rabbit backward, keep the whole body in a stretched state, close the waist fixing device 9 opened to the left and right, and further tighten the stoppers 11 to prevent the waist fixing device 9 from opening. did. (5) Hold the handle 12 and slide the upper base 2 appropriately,
The position of the waist fixing device 9 was adjusted so that it was covered from around the hip joint of the rabbit to the toes. By the above work, the rabbit could be easily fixed with the back exposed greatly. When the rabbit is fixed

FIG. 2 schematically shows. After that, hair cutting was performed using a hair clipper. Rabbits did not run wild during the hair-cutting work, and there was no damage to the back of the rabbits, and the hair could be cut smoothly.

[0017]

INDUSTRIAL APPLICABILITY As described above, according to the animal immobilizer of the present invention, experimental animals such as rabbits and guinea pigs can be easily immobilized. Mowing can be performed, and animal experiments such as skin irritation test can be efficiently performed.
