Description

  The present invention relates to a stationary fixture for small animals such as mice, rats, and rabbits that are generally used for experiments.

  Small animals to be used for experiments need to be fixed in order to maintain a stationary state during various experimental work including blood collection. Thus, conventionally, for such fixation, after putting a small animal in a box-type container containing a sponge, pressing and fixing with a lid from above, or after putting a small animal in a pipe-type container opened only on one side, A method of inserting and sliding the pressing portion from the opening and fixing it has been adopted (see Non-Patent Document 1, for example).

However, fixing by such a conventional method is merely pressing and fixing from the top and bottom of the small animal in the case of a box-type container and from the front and back of the small animal in the case of a pipe-type container, and fixing so as to wrap the entire body. Because it was not intended, the stress caused by partial excessive pressure often induces rampage during blood sampling and other tasks, sometimes biting workers or hurting small animals There was a problem.

  The present invention has been made in view of the conventional problems as described above, and provides a stationary fixture for small animals that can be fixed so as to wrap the entire body of a small animal very easily and safely. It is an issue.

  As a result of various studies to solve such problems, the present inventor can obtain extremely good results by using the habit of a small animal that escapes and hides in a narrow and dark place to protect himself. The present invention has been completed.

  That is, the present invention provides a small animal stationary fixture characterized by comprising a cylindrical body having an inner diameter that gradually decreases from one large-diameter opening toward the other small-diameter opening. Is a solution.

  The cylindrical body according to the present invention has an inner diameter that gradually decreases from one opening toward the other, so that the head of the large-diameter opening is held with the tail of a small animal. If it is positioned, the animal will enter the direction of the small-diameter opening and cannot move naturally without forcing it.

  Therefore, by using the stationary fixture for small animals of the present invention, the small animal can be stationary and fixed in a state where the whole body is softly wrapped in a very safe and secure manner, so that an animal feel can be obtained. Various tasks associated with experiments such as blood sampling, measurement of body weight and height, movement, etc. can be performed smoothly, and unlike forcing and fixing, there is less stress on small animals and there is also the risk of crushing Absent.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 is a schematic perspective view of a stationary fixture for small animals of the present invention, FIG. 2 is a schematic plan view of the stationary fixture for small animals of the present invention in a state where a small animal tail outlet is formed, and FIG. 3 is a book in use. It is a schematic perspective view of the stationary fixture for small animals of the invention.

  1 to 3, reference numeral 10 denotes a cylindrical body, one of which has a large-diameter opening 11 and the other of which is a small-diameter opening 12, both of which has an inner diameter and an outer diameter of the large-diameter opening 11. The diameter gradually decreases from the diameter opening 11 toward the small diameter opening 12.

  The specific inner diameter dimension of the tubular body 10 and the degree of gradually decreasing the diameter can be appropriately selected according to the type and size of the small animal to be fixed stationary.

  Incidentally, as will be described later, the large-diameter opening 11 is used as an entrance / exit for a small animal, and the small-diameter opening 12 is used as a breathing opening for the small animal when stationary.

Although the material of the cylindrical body 10 is not particularly limited, for example, it is desirable to use a synthetic resin sheet or film having a foldable flexibility because it can be efficiently joined and formed into a cylindrical shape by means such as heat sealing. In addition, since the obtained cylindrical body 10 itself can be bent, it can be efficiently transported and stored in a flat state, and as described later, after fixing a small animal stationary, the large-diameter opening 11 side can be easily folded. It is desirable in that it can be bent and sealed. Incidentally, 10a has shown the heat seal junction part at the time of shape | molding the cylindrical body 10 with the above synthetic resin sheets and films.
Moreover, it is more desirable to use the cylindrical body 10 as a transparent body because it can be operated while observing the appearance of a small animal from the outside.

  Reference numeral 10b denotes a protruding bottom, which is coupled to the large-diameter opening 11 side of the cylindrical body 10. As will be described later, the protruding bottom portion 10b is used as a receiving portion for a small animal, and the small animal smoothly enters the inside of the tubular body 10 by setting and guiding the small animal on the protruding bottom portion 10b.

  The specific method of forming the projecting bottom portion 10b is not particularly limited. For example, after forming a cylindrical body, a method of cutting the end portion obliquely, or a pre-shaped development that is in a state of being cut obliquely. A simple method is a method of forming a cylinder using a sheet or a film.

  Reference numeral 13 denotes an easily excision processing portion, which is provided at the upper edge portion of the cylindrical body 10 on the side of the large-diameter opening portion 11 for forming the outlet 14 of the tail P of the small animal.

  As a specific processing method of the easily cut portion 13, there is no particular limitation on perforations, cuts, cuts, combinations thereof, or the like as long as the extraction opening 14 is easily cut and formed. For example, the large diameter of the cylindrical body 10 A perforation line 13a having an appropriate length is provided in the longitudinal direction (lateral direction in FIG. 1) from the opening 11, and the saw blade is formed in the short direction (vertical direction in FIG. 1) from the heat seal joint 10a of the cylindrical body 10. It is possible to form a suitable number of cut-out portions 13b corresponding to the length of the perforation line 13a, and to draw out the outlet 14 having a size corresponding to the size of the small animal by tearing in the vertical direction and tearing in the horizontal direction. It is desirable because it can be easily formed.

Reference numeral 15 denotes a locking hole, which is provided on the projecting piece 16 connected to the heat seal joint 10a located at the upper edge of the small diameter opening 12 side.
If the locking hole 15 is inserted and locked to a hook (not shown) attached to a suitable part, the cylindrical body 10 is fixed and held, so that blood collection or the like can be performed more smoothly.

  Next, the usage method of the stationary fixture for small animals of this invention based on embodiment shown in FIG. 1 is demonstrated.

  First, holding the tail of a small animal, it is guided and set to the protruding bottom 10b on the large diameter opening 11 side of the cylindrical body 10 shown in FIG. Then, according to the habit, the small animal enters and moves in the depth direction of the cylindrical body 10 that is narrower than the small animal, that is, toward the small-diameter opening 12, and naturally stops where it cannot move. Therefore, as shown in FIG. 3, an extra cylindrical body portion on the large-diameter opening portion 11 side is bent as a folded portion 10c, and is appropriately sealed with a stopper 17 such as an adhesive tape, stapler, clip, etc. If it is fixed to the body 10 body, the small animal inside cannot be moved backward, and the whole body is fixed and fixed in a state of being softly wrapped by the cylindrical body 10, so that it is possible to smoothly measure the body weight and move work. Can be done. In this state, the small-diameter opening 12 serves as a small animal's breathing port. In addition, after completion | finish of work, the sealing fixation of the folding | returning part 10c is cancelled | released, a small animal is taken out from the large diameter opening part 11, and is released.

  Further, when it is necessary to draw out the tail P of a small animal for blood collection or the like, it is torn to the perforation line 13a in the vertical direction from an appropriate portion of the cut portion 13b according to the size of the small animal, and then the perforation line. If the upper edge portion of the cylindrical body 10 is excised along the large-diameter opening portion 11 along the line 13a, the extraction port 14 is formed at the excision site as shown in FIG. The tail P can be pulled out.
