Abstract
本发明公开了一种大鼠固定器，为一主板上设有模拟大鼠躯干部的区域，在该区域大鼠胸腹腔的两侧设有槽口，槽口中插入固定板，两固定板的两端相对位置设有用于插入固定插销的圆孔。本发明的优点是固定过程及固定后均不伤害大鼠，不会造成瘀伤，同时能保护操作人员安全；可同时进行腹腔注射，灌胃及针灸；实现了灵活地固定，大鼠即不能动弹，又处于一个相对较为松驰的状态。
The invention discloses a rat fixer. A main board is provided with an area for simulating the torso of a rat. Notches are arranged on both sides of the thorax and abdomen of the rat in the area, and a fixing plate is inserted into the notch. The opposite positions of the two ends are provided with round holes for inserting the fixing pins. The invention has the advantages of not harming the rats during the fixation process and after fixation, without causing bruises, and at the same time can protect the safety of the operator; can perform intraperitoneal injection, gavage and acupuncture at the same time; realize flexible fixation, and the rats cannot Moving, it is in a relatively relaxed state.
Description
Technical field
The present invention relates to a kind of animal holder tool, particularly a kind of rat fixator.
Background technology
Rat fixator is one of utensil of zoopery indispensability, and traditional rat fixator all exists following problem:
(1) owing to being that the pressure of the most of health of whole body is fixed, easily in experimentation, cause injury with blood-stasis, affect experimental result;
(2) body surface exposes insufficiently, and this point especially seems particularly serious in the relevant experiment of Chinese medicine acupuncture, and causing cannot acupoint selection;
(3) because incidence is fixed, so general conventional rat fixator can not meet the needs of conventional gavage.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of fixing flexibly, and rat can not be moved, and in relaxed state comparatively, the rat fixator of being convenient to carry out lumbar injection, gavage and acupuncture.
In order to solve above technical problem, the invention provides a kind of rat fixator, is the region that a mainboard is provided with simulation rat trunk, is provided with notch in the both sides of this region rat splanchnocoel, in notch, insert fixing head, four bights of mainboard reverse side are provided with passive pillar.
On described mainboard, corresponding rat splanchnocoel region is engraved structure, is convenient to carry out lumbar injection, and head and extremity are all fixing without forcing, and are convenient to carry out gavage and acupuncture.
The two ends relative position of described two fixing heads is provided with the circular hole for inserting Fixed latches, makes rat between two fixing heads, interregional under Fixed latches.
Advantage of the present invention is:
(1) avoid injuring experimenter in rat fixation procedure especially abecedarian;
(2) fixation procedure and fixing after all do not injure rat, can not cause injury with blood-stasis, can protect operator safety simultaneously;
(3) can carry out lumbar injection, gavage and acupuncture simultaneously;
(4) realized flexibly and having fixed, rat is unable to stir any more, again in a comparatively loose state;
(5) the simplest structure for the present invention, has realized the fixing of non-invasi;
(6) after rat is fixed, the health overwhelming majority, in exposed state, is conducive to carry out various experimental implementation.

The specific embodiment
Refer to shown in accompanying drawing, the invention will be further described.
As depicted in figs. 1 and 2, the invention provides a kind of rat fixator, is the region that a mainboard 1 is provided with simulation rat trunk, is provided with notch 2 in the both sides of this region rat splanchnocoel, inserts fixing head 7 in notch 2.Four bights of mainboard reverse side are provided with passive pillar 4, and its highly a little higher than fixing head 7 exposes the length of mainboard 1.
On described mainboard 1, corresponding rat splanchnocoel region is engraved structure 3, is convenient to carry out lumbar injection, and head and extremity are all fixing without forcing, and are convenient to carry out gavage and acupuncture.
The two ends relative position of described two fixing heads 7 is provided with the circular hole 5 for inserting Fixed latches 6, makes rat between two fixing heads 7, interregional under Fixed latches 6.
Described pillar 4 also plays a supportive role, and its height will exceed fixing head 7 and insert the length of mainboard 1.
When the present invention uses, fixing head 7 is inserted in the notch 2 of mainboard 1, rat is positioned over to the region between two fixing heads 7, after rat extremity all expose, fixing head 7 is continued to insert, after two pairs of circular holes 5 that expose on fixing head 7, immediately Fixed latches 6 is inserted, rat is completely fixed.
The present invention makes full use of the architectural feature of rat health, employing meets the fixing means of rat body structure, make full use of the transverse diameter (being greater than breast, abdominal cavity) of the upper and lower basipodium of bilateral bottom, take breast, abdominal cavity as fixed object, use the trapezoidal square frame of class of a simulated torso portion to be fixed, because extremity are in de-power state, rat cannot roll and wait struggle to move, can reach loose fixing object: can fix, not affect again the function in breathing and abdominal cavity.
The present invention is also provided with strip gab on the mainboard 1 at position, rat back center, can be for acupoint selection; Mainboard in abdominal part center and flank portion also respectively has strip gab, can be for acupoint selection and lumbar injection.
Operation principle of the present invention: make full use of the architectural feature in rat chest, abdominal part and extremity hip (shoulder) joint, realize a kind of fixing object flexibly.Concrete is presented as: the thoracic cavity of rat and the structure in abdominal cavity, girth are different, the class barrel shaped structure that thoracic cavity is made up of breastbone, rib and spinal column, there is greatly fixing shape in thoracic cavity, little and the shape in abdominal cavity is fixing, comparatively soft, on this basis, the joint of extremity root and trunk, muscle is many and loose, puts a trapezoidal framework in the bottom, joint (the quite structure place of axillary fossa) of forelimb and the top (quite suprailium ridge place) in hind leg joint, can realize not strap-on fixing.
Secondly, because this structure does not have the structure that can contact at the extremity place of rat, rat is after fixing, and extremity are without origin of force, fixing after, rat, in losing the state of power, there will not be struggle, is beneficial to fixingly, there will not be again the injury because of appearance after fixing struggle.
Claims (3)
1. a rat fixator, it is characterized in that: be the region that a mainboard is provided with simulation rat trunk, both sides at this region rat splanchnocoel are provided with notch, insert fixing head in notch, and the two ends relative position of two fixing heads is provided with the circular hole for inserting Fixed latches.
2. rat fixator according to claim 1, is characterized in that: on described mainboard, corresponding rat splanchnocoel region is engraved structure.
