Description
Technical field
The present invention relates to tail vein injection medicine or the arterial blood extracting of laboratory animal nude mice that a kind of zoopery that is applied to researchs such as medicine, food uses, white mice, rat, black Mus etc. and take necessary control to make its certain position keep a resting state and be convenient to a kind of experimental mouse holder of experimenter's operation experimental mouse.
Background technology
Current, the experimenter uses is drum type brake Mus box fixing device mostly or pushes down the Mus tail with the edge of box, then to the caudal vein injectable drug.But the fixed Mus of drum type brake Mus box often struggles afterbody is produced counteracting force and move and be not easy to tail vein injection, and afterbody also not have the operation planar placed, operation is inconvenience very, usually makes the intravenous injection termination and repetitive operation; The Mus tail is pushed down at the edge of box, damages the Mus tail easily, owing to push down the arteries of Mus tail, influences blood circulation, often produces red and swollen congestion, causes the caudal vein injection in later stage normally not carry out.Especially the vein blood vessel of Mus tail two sides with below, must reverse afterbody during tail vein injection, with facing up of a vein blood vessel, causing vein blood vessel so is not the linear of level, makes intravenous injection increase difficulty.
The experimenter adopts the fixedly method of animal of holding in hand sometimes, but just very inconvenient for white mice, nude mice, because its build is too little, is not easy to two people and operates simultaneously, and waste of manpower.
The Chinese utility model patent of number of patent application 201020116953.1 discloses a kind of white mouse holder: comprise pedestal and U-shaped cylindrical shell, pedestal one side is fixed with backboard, and the pedestal opposite side is provided with two limiting plates; Respectively be connected with a screw between backboard both sides and cylindrical shell, be provided with slide plate between two limiting plates, slide plate one end is fixed with pressing plate; The other end is provided with sliding tray; Pedestal is connected with housing screw, is fixed with the cervical fixation ring through hold-down screw on the pressing plate, and the cervical fixation ring is connected with hasp.This patent is well suited for the head experiment of Mus, but is not suitable for the caudal vein injection, and it does not have Mus tail clamping device and caudal vein injection operation platform.
The tail vein injection difficulty of black rat and transgenic black rat is very big; The speed of injectable drug and dosage all will be controlled accurately; Especially the transgenic black rat is very expensive; In case the tail vein injection failure just possibly cause than the large economy loss, the special-purpose experimental mouse holder of development is the urgent problem that but need solve of laboratory.
Summary of the invention
The objective of the invention is to overcome existing experimental mouse holder and exist the caudal vein injection operation inconvenient, and usually make the intravenous injection termination and repetitive operation, also often damage the problem of caudal vein; The present invention provides a kind of experimental mouse holder; Can make the caudal vein blood vessel maintenance level shape that is in line, the intravenous injection difficulty is reduced, have easy for operation, reduce damage to the caudal vein blood vessel; Zoopery is carried out smoothly, made experimental result have more science.
