Abstract
The invention relates to a perfusion apparatus for small animals, aiming to realize perfusion of brain tissues of small animals in experiments of small animals such as rats and rabbits. The perfusion apparatus for small animals is provided with a perfusion case which is of a sealed structure and connected with a pressuring catheter and a perfusion catheter. The other end of the pressurizing catheter is connected with an air pressurizing bag or air pressurizer. The whole perfusion case is mounted on a support and is adjustable in height, and is provided with an observation window for observation of liquid level. Perfusate returns to the brain tissues of the small animals after intraperitoneal injection, so that purposes of the experiments are achieved. The perfusion apparatus is small, light and portable, is convenient to carry without limitation of experiment sites, can be applied to perfusion of brain tissues of small animals widely, and is an essential instrument for tissue slicing and staining of small animals in the future. By the perfusion apparatus, inconvenience in manual perfusion during conventional animal experiments is overcome, perfusion quantity and time of animal brain tissues are more accurate, and operations can be more systematized and convenient.
Description
Technical field
The present invention belongs to the laboratory animal equipment, and is quick and easy when zoopery, practical.Belong to medical instruments field.
Background technology
Cerebral tissue perfusion is the modal experimental technique of zoopery, in traditional zoopery, adopts manual perfusion, and not only inconvenience, and animal brain's groundwater increment, time are not accurate enough.
Summary of the invention
Goal of the invention the invention provides zoopery perfusion apparatus, and is easy to carry, is packaged type.
Technical scheme toy filling apparatus, it has the perfusion case, and this perfusion case is on closed structure and its, to be connected with pressurization conduit and perfusion cannula; The other end of pressurization conduit is connected with air pressurized air bag or air pressurized instrument; Perfusion case integral installation is adjustable at the support height, on the perfusion case, also has the observation window of observing liquid level simultaneously.
The perfusion case is rack-mount by movable nut, pours into simultaneously box top spiral perfusion cap is housed.
Switch is housed on perfusion cannula, is convenient to control at any time flow.
The present invention mainly comprises filling apparatus, can regulate and control support and attachable air pressurized air bag, pours into input pipe.Be mainly in animal perfusion experiment, after by device for casting, making infusion liquid pass through lumbar injection, through gyrus infusate flow animal brain, and control the perfusion animal time by pressue device, reach experiment purpose.
The present invention design has fully demonstrated, and convenient, integrated, simple and easy, theory efficiently, can be applied to school, hospital, the various laboratorys of R&D institution.Popularizing application prospect is good, and wide because of this Instrumentation Operating Areas, purposiveness is strong, and processing technology is simple and with low cost.
The accompanying drawing explanation
Figure is structural representation of the present invention.
The specific embodiment
As shown be specific embodiment of the invention structure.The toy filling apparatus, it has perfusion case 1, and this perfusion case 1 is connected with on closed structure and its pressurize conduit 3 and perfusion cannula 2; The other end of pressurization conduit 3 is connected with air pressurized air bag or air pressurized instrument; Perfusion case 1 integral installation is adjustable at support 4 height, on perfusion case 1, also has the observation window 7 of observing liquid level simultaneously.Perfusion case 1 is arranged on support 4 by movable nut 8, pours into simultaneously case 1 top spiral perfusion cap 6 is housed.Switch 5 is housed on perfusion cannula 2.
In animal perfusion experiment, after by device for casting, making infusion liquid pass through lumbar injection, through gyrus infusate flow animal brain, and control the perfusion animal time by pressue device, reach experiment purpose.
The present invention is a kind of toy simple animal filling apparatus, to meet in toy (white mice, rabbit) experimentation, animal brain's perfusion is used.It through gyrus infusate flow animal brain, has reached experiment purpose after by perfusion easy device, making infusion liquid pass through lumbar injection.This animal filling apparatus volume is little, and profile is light and handy, is packaged type, not limited by experimental site, is convenient for carrying.Can be widely used in the perfusion experiment of experimental animal cerebral tissue, be after animal brain cut into slices, variegated indispensable instrument.Overcome in traditional zoopery the inconvenience of manual perfusion, made animal brain's groundwater increment, time more accurate, operated more adding system, convenient.
