Wherein, the parts name of labelling correspondence is called in the accompanying drawing: 1-head fixture, and 2-afterbody fixture, 3-anaesthetizes part, 4-fixed bar, 5-connecting rod, 6-screw rod, 7-through hole, 8-oxygen catheter, 9-anesthetis conduit.
The specific embodiment
The invention will be further described below in conjunction with drawings and Examples, and embodiments of the present invention include but not limited to the following example.
Embodiment 1
As shown in Figure 1, big rat holder comprises head fixture 1, the afterbody fixture 2 that links to each other with head fixture 1 bottom, and the anesthesia part 3 that links to each other with head fixture 1 top; Described afterbody fixture 2 top ends are provided with plural crack, and the cross section of described head fixture 1 enlarges from the top to the bottom gradually, and the cross section of described afterbody fixture 2 reduces from the top to the bottom gradually; Described head fixture 1 and afterbody fixture 2 are cavity structure, and the top of head fixture 1 and afterbody fixture 2 and bottom all are hatch frame.Described head fixture and afterbody fixture are complete bodily form designs according to rat, and its head and afterbody are narrower, and the middle part broad, so fixture becomes said structure with the afterbody anchor designs.Certainly head fixture and afterbody fixture also can be designed to the semiellipsoid structure, just two ends are opening form, when combining with the afterbody fixture, the head fixture just become the ellipsoid of a cavity structure, its two ends are cylindrical structure, one end is ventilated for the ease of head, and the other end is convenient to tail and is stretched out outside of the present invention.
Further, for head fixture 1 and afterbody fixture 2 can finely be fixed, when preventing that rat from twisting within it, the head fixture separates with the afterbody fixture; Also be provided with the fixed bar 4 of fixedlying connected on the described afterbody fixture 2 with it, described fixed bar 4 also is fixedly connected with connecting rod 5 away from an end of afterbody fixture, described connecting rod 5 also is provided with plural first screwed hole away from an end of fixed bar, head fixture 1 be provided with connecting rod 5 on equal-sized second screwed hole, described head fixture 1 fixes by the screw rod 6 that passes first screwed hole and second screwed hole with connecting rod 5.When rat being put into head fixture and afterbody fixture, according to its bodily form and length head fixture and afterbody fixture are drawn close to the centre, the vertical crack of afterbody fixture this moment will narrow down, thereby being convenient to the afterbody fixture can be encased by the head fixture smoothly, when head fixture and afterbody fixture reach the appropriate location, only need screw rod passed from first screwed hole and pass second screwed hole again and fix, thereby head fixture and afterbody fixture are fixed.Because of the rat bodily form and being uneven in length, so connecting rod is provided with a plurality of first screwed holes, so that when different rats are experimentized, can make things convenient for the experimenter to operate well with head fixture and the fixation of afterbody fixture.
In order better to realize air permeable effect, and can carry out subcutaneous and the abdominal part injection, be equipped with plural through hole 7 on described head fixture 1 and the afterbody fixture 2 rat.
Simultaneously, in order better to realize the present invention, described anesthesia part 3 tops are provided with oxygen catheter 8 and anesthetis conduit 9, and between anesthesia part 3 and head fixture 1 top by being threaded.Being provided with like this is for when not needing to anaesthetize and reviving, and only needs the anesthesia part is separated with the head fixture, for rat provides ventilative; When needs are anaesthetized and revive, only need the anesthesia part is connected with the head fixture, thereby rat aerating oxygen and anesthetis are reached the effect of reviving and anaesthetizing by oxygen catheter and anesthetis conduit.
In addition, described head fixture 1, afterbody fixture 2, anesthesia part 3 and connecting rod 5 constitute by plastic material.Simultaneously in order better to recognize rat in situation of the present invention, can just above-mentioned parts all make transparent, thereby can observe the state of rat accurately, make things convenient for the experimenter to operate.
As shown in Figure 2, big rat holder comprises head fixture 1, the afterbody fixture 2 that links to each other with head fixture 1 bottom, and the anesthesia part 3 that links to each other with head fixture 1 top; Described afterbody fixture 2 top ends are provided with plural crack, and the cross section of described head fixture 1 enlarges from the top to the bottom gradually, and the cross section of described afterbody fixture 2 reduces from the top to the bottom gradually; Described head fixture 1 and afterbody fixture 2 are cavity structure, and the top of head fixture 1 and afterbody fixture 2 and bottom all are hatch frame.Described head fixture and afterbody fixture are complete bodily form designs according to rat, and its head and afterbody are narrower, and the middle part broad, so fixture becomes said structure with the afterbody anchor designs.Certainly head fixture and afterbody fixture also can be designed to the semiellipsoid structure, just two ends are opening form, when combining with the afterbody fixture, the head fixture just become the ellipsoid of a cavity structure, its two ends are cylindrical structure, one end is ventilated for the ease of head, and the other end is convenient to tail and is stretched out outside of the present invention.
Further, for head fixture 1 and afterbody fixture 2 be can be good at fixing, when preventing that rat from twisting within it, the head fixture separates with the afterbody fixture, inside, described head fixture 1 bottom is provided with female thread, also is provided with the external screw thread that is positioned at the below, crack and matches with female thread on the afterbody fixture 2.When rat is positioned at head fixture and afterbody fixture, only need rotation head fixture or afterbody fixture, fix by female thread and external screw thread; Because the rat bodily form is different with length, so in rotary course, rat hour, the part that the afterbody fixture enters the head fixture is just more, and cross between the crack apart from shortening at rotary course, to guarantee that the afterbody fixture can enter in the head fixture smoothly, is fixed on rat in head fixture and the afterbody fixture thereby reach.
In order better to realize air permeable effect, and can carry out subcutaneous and the abdominal part injection, be equipped with plural through hole 7 on described head fixture 1 and the afterbody fixture 2 rat.
Simultaneously, in order better to realize the present invention, described anesthesia part 3 tops are provided with oxygen catheter 8 and anesthetis conduit 9, and between anesthesia part 3 and head fixture 1 top by being threaded.Being provided with like this is for when not needing to anaesthetize and reviving, and only needs the anesthesia part is separated with the head fixture, for rat provides ventilative; When needs are anaesthetized and revive, only need the anesthesia part is connected with the head fixture, thereby rat aerating oxygen and anesthetis are reached the effect of reviving and anaesthetizing by oxygen catheter and anesthetis conduit.
In addition, described head fixture 1, afterbody fixture 2, anesthesia part 3 and connecting rod 5 constitute by plastic material.Simultaneously in order better to recognize rat in situation of the present invention, can just above-mentioned parts all make transparent, thereby can observe the state of rat accurately, make things convenient for the experimenter to operate.
According to the foregoing description, just can realize the present invention well.What deserves to be explained is; under the prerequisite based on the said structure design, for solving same technical problem, even some that make in the present invention do not have substantial change or polishing; the essence of the technical scheme that is adopted is still the same with the present invention, so it also should be in protection scope of the present invention.
