Abstract

Local irradiation device of animal mount and animal belongs to medical field. The utility model discloses the technique limitation that the local treatment of accepting irradiation or other forms to present animal exists provides that a structure is simple and easy, low cost, can realize many animals and accept to be equal the device of dosage local irradiation simultaneously. The technical scheme who takes lies in: the device by shielding case, animal mount, cross bear, a plurality of shield ring constitutes. The theory of operation is withdrawn the shield ring or misplaces to put through the selectivity to realize that the animal part exposes other position conductively -closeds. The utility model discloses a predominant use does: local radiation treatment is accepted to the animal. The utility model discloses an advantage does: the simple structure, resources are saved, it is little to the animal injury, can firmly fix the animal under the not anesthetic condition moreover, can realize many animals to accept to equate dosage simultaneously and shine that can show very much lands improves work efficiency.

Description

Animal fixed mount and animal local irradiation device

Technical field

This utility model relates to the animal irradiation devices required for a kind of teaching, scientific research, veterinary.

Background technology

Had multiple to the device of animal enforcement radiation irradiation (or other forms of topical therapeutic) at present, some complex structures, use more time-consuming; The animal being only defined in specific build had; Some animals are fixing loosely, have animal to struggle unavoidably, cause radioactive dose deviation in irradiation process; And the device of the dose operation such as do not have many animals simultaneously, but scientific research or teaching need every treated animal sample size to be greater than 5 usually, like this, work animal being implemented to local irradiation just must consume a lot of time.Limit to by prior art, the local irradiation under the non-narcotic situation of animal, especially the while of many animals, the task of local irradiation is usual loaded down with trivial details consuming time.

Utility model content

This utility model provide a kind of construct simple and easy, with low cost, use many animals flexibly to accept the device of equivalent dose local irradiation simultaneously, the technical scheme taked is:

A kind of animal fixed mount, is characterized in that: surface, for netted or cellular, can realize fixing in the optional position of fixed mount and direction many animals, under the situation of anaesthetizing or do not anaesthetize, can both implement to irradiate.

A kind of animal local irradiation device, is characterized in that: be made up of the shading ring of shielding box, above-mentioned animal fixed mount and multiple flexible; Shielding box bottom surface and side are one, and end face is empty, and box inwall has two annular projections from down to up, and be respectively used to carrying animal fixed mount and cross carrier, multiple ring is fitted together to mutually, is carried on the end face of shielding box by cross carrier.

Preferably, the shielding box of animal local irradiation device is cylindrical or truncated cone-shaped.

Preferably, this animal local irradiation device is double-deck or multilamellar.

This device is made up of shielding box, animal fixed mount, cross carrier, shading ring (multiple).

Shielding box is cylindrical, and material of main part is plumbous, has shielding action to lonizing radiation.

Shielding box bottom surface and side are one, and end face is empty, and box inwall has two annular projections from down to up, are respectively used to carrying animal fixed mount and cross carrier.

Animal fixed mount is circular, metal material, and surface is in netted or cellular, and the rope of surface void convenient constraint animal passes.

Shading ring material is plumbous, and have shielding action to ray, multiple ring is fitted together to mutually, is carried on the end face of shielding box by cross carrier, and whole shading rings can block ray completely, by selecting flexibly to remove one or more shading ring, realizes ray local irradiation.

Auxiliary consumptive material be with low cost, that market is common self-locking type plastic nylon cable tie (such as specification be 3*100mm can be used for fetter mice), for constraint and fixing animal foot and head.

This utility model compared with prior art has following beneficial effect:

This utility model simple structure, economizes on resources, little to animal injury, and can firmly fix animal when not anaesthetizing, and can realize many animals and accept equivalent dose irradiation simultaneously, can increase work efficiency very significantly.

Shielding box of the present utility model according to use needs, can also make truncated cone-shaped, taper shape or other spatial forms.

This utility model applicable animal build is in extensive range, and the product of same model both can realize the local irradiation of mice, also can realize rat, the local irradiation of other laboratory animal such as rabbit.

The selectable exposed area of this utility model is extensive, by removing one or more shading ring, being put by the dislocation between shading ring, realizing the difference of irradiated area.

According to radiation intensity and the distribution of irradiation apparatus, this screening arrangement also can make bilayer or multilamellar, with ¹³⁷csgamma beam exposure apparatus is example, radioactive source is irradiated by top and bottom simultaneously, so it is all empty that this screening arrangement also can make bottom surface, upper bottom surface putting thus regulating the region irradiated all by shading ring, animal fixing device can put monolayer or bilayer.

Detailed description of the invention

Embodiment one: many mices accept equivalent dose abdominal irradiation simultaneously

The first step, animal is fixed on animal fixed mount, as Fig. 2, by the tail end of self-locking type plastic nylon cable tie 6 through self head, form a collar, strain after entangling the extremity of animal, until the extremity of animal can not be escaped and the degree that can not damage to animal, now, band is automatic locking, then by the tail end of band 6 through after the hole on animal fixed mount 5 surface, by band tail end clip or use bullhead self-locking clip, four band tail ends are fixed between two.After extremity are fixing, with a new self-locking nylon cable tie 6, the head of animal is entangled, and automatic locking after band being passed through animal fixed mount surface void, realize animal head to fix.Whole process is convenient rapidly, the basic no pain of animal, and due to band longer, so, very little by the probability of animal attacks.Many animals are centrosymmetric on the animal fixed mount of circle.

Second step, is placed on the shielding box shown in Fig. 1 inner, is carried by the annular projection 2 of inwall by the animal fixed mount fixing animal, experiment or operation object, are depended on upward in animal abdominal part or back.

3rd step, is placed on the shielding box shown in Fig. 1 inner, is carried, be placed on successively by shading ring 4 on cross carrier, removed by shading ring corresponding for animal abdominal region by the annular projection 3 of inwall by cross carrier, position signal is as Fig. 3.

Whole process is consuming time few, and efficiency is high, and the dosage of animal local irradiation is identical with position, ensure that the experiment concordance of exposure dose and the repeatability of scientific data.

Embodiment two: rabbit head irradiates

Because rabbit build is comparatively large, when irradiation apparatus size allows, rabbit is fixed on animal fixed mount according to the method for embodiment one, is misplaced by shading ring and put, as Fig. 4, dash area 7 by rabbit head exposure in roentgenization.

This device is applicable to multiple animal, the local irradiation of multiple position, also can realize animal fix after total irradiation.
