Abstract

Disclosed is a small animal intraventricular injection compensator for injecting a drug into a desired location through a syringe, the compensator including: a guide part provided with a guide hole into which a needle of a syringe is inserted; a body comprising an upper cavity provided inside thereof and a cradle provided to seat the guide part on an upper side thereof; and a fixation part integrally provided with the body or separately provided, and comprising a lower cavity provided to allow a head accommodation space, which a head of a small animal may enter into or exit from, to be provided inside thereof by corresponding to the upper cavity.

First claim

1 . A small animal intraventricular injection compensator, the compensator comprising:
a guide part provided with a guide hole into which a needle of a syringe is inserted; a body comprising an upper cavity provided inside thereof and a cradle provided to seat the guide part on an upper side thereof; a fixation part integrally provided with the body or separately provided, and comprising a lower cavity provided to allow a head accommodation space, which a head of a small animal can enter into or exit from, to be provided inside thereof by corresponding to the upper cavity; and an indicator provided at the guide part or the body and provided to allow an experimenter to see with naked eyes a predetermined portion of the head of the small animal inserted into the head accommodation space at an upper side of the guide part or the body.

2 . The compensator of claim 1 , wherein the indicator is a gap having a predetermined length and width provided between a side surface of the guide part and a side surface of the cradle, on which the guide part is seated, wherein, using the gap, it can be determined whether the head inserted into the head accommodation space is disposed at a right position.

3 . The compensator of claim 1 , wherein the guide part further comprises a guide groove for inserting and fixing a syringe, wherein sectional shapes of both the guide groove and a tip end side of the syringe inserted into the guide groove coincide with each other.

4 . The compensator of claim 1 , wherein whether or not the head of the small animal is in place is determined by determining whether or not a tip of an eye tail of the small animal coincides with a fore-end or tip end portion of the gap.

5 . The compensator of claim 3 , wherein the guide hole is eccentric by a predetermined distance to one side with respect to a centerline of the guide part, or a pair of guide holes is each provided to be spaced by a predetermined distance to opposite sides with respect to the centerline of the guide part.

6 . The compensator of claim 1 , further comprising: an anesthesia gas inlet provided on an opposite side of the head accommodation space.

7 . The compensator of claim 1 , wherein the guide part further comprises an incision portion provided inward to allow the experimenter to check with the naked eye a degree of protrusion of the needle of the syringe from the lower side where the guide hole is provided.

8 . The compensator of claim 1 , wherein the guide part, the body, and the fixation part are provided integrally, or are coupled to each other by magnetic force.

9 . The compensator of claim 1 , wherein the guide part comprises:
a second guide part seated on the cradle; and a first guide part coupled to a top side of the second guide part.
