Abstract
The utility model discloses a mouse temporary constraint net used in an experiment. The mouse temporary constraint net comprises a net body, and is characterized in that the net body is a cone-shaped net bag, and the rear end of the cone-shaped net bag is provided with an opening. The mouse temporary constraint net used in the experiment is in the cone-shaped net bag structure, so an animal can be firmly fixed in the net bag and cannot turn the head or open the mouth, safety of an experiment person is guaranteed, and suffering of the experimented animal is reduced. When the mouse temporary constraint net is used, the opening is opened, the animal actively climbs into the point end of the net bag, then the opening and the tail of the animal are bundled together with wires, operation procedures for the experimented animal are simplified, and the mouse temporary constraint net is suitable for being used by students who do not have experience and can be popularized and used in universities and research and development institutions where experimented animals are used.
Description
Technical field
This utility model relates to a kind of restraint device, is specifically related to a kind of experimental rat class and fetters net temporarily.
Background technology
Along with the fast development of life sciences, the usage quantity of laboratory animal and frequency constantly increase in the teaching and scientific research activity.How in the laboratory animal use procedure, to reduce the misery of laboratory animal, ensure operator's the always extremely concern of researcher of safety.
In experimentation, find; when using rat, mice; experimenter, particularly unfamiliar student when grasping animal and carry out various experimental implementation, usually can occur owing to grasp the inadequate standard of laboratory animal cause laboratory animal stress, grabbed the situation of stinging by laboratory animal.Therefore, need a kind of device, to simplify the laboratory animal operation sequence, guarantee experimenter's safety, reduce simultaneously the misery of laboratory animal, and be convenient to unfamiliar student's use.
Summary of the invention
Goal of the invention of the present utility model provides a kind of experimental rat class and fetters net temporarily, can simplify the laboratory animal operation sequence, guarantees experimenter's safety, can also reduce the misery of laboratory animal simultaneously, and is convenient to unfamiliar student's use.
To achieve the above object of the invention, the technical solution adopted in the utility model is: described dictyosome is the taper mesh bag, and described taper mesh bag rear end is provided with opening.
In the technique scheme, described dictyosome length is 15～22 centimetres, and opening diameter is 10～16 centimetres, and the dictyosome conical apex angle is 36 °～46 °.
Preferred technical scheme, the dictyosome conical apex angle is 39 °～44 °.
In the technique scheme, described dictyosome is made of nylon mesh grid.
Muroid natural disposition is timid, can strive to find comparatively safe place and hide in open environment.We have invented the experimental rat class and have fettered net temporarily according to this behavioristics's characteristic of animal.The muroid animal is positioned on the spacious experiment table top, places a taper mesh bag at the animal dead ahead, animal can initiatively constantly climb into to the mesh bag front end as possible, and final animal is fixed in the front end small space.After animal tail and mesh bag rear end is fixing together, animal just was firmly fixed in mesh bag, both can't reverse end for end also can't open face.The mesh bag material therefor can be guaranteed the animal eupnea for ventilative nylon material.
Because technique scheme is used, this utility model compared with prior art has following advantages:
1. to fetter net be taper mesh bag structure to experimental rat class of the present utility model temporarily, can firmly be fixed on animal in the mesh bag, make it can't turn around also can't open face, thereby guaranteed experimenter's safety, reduced the misery of laboratory animal, and only need open bag mouth when using and initiatively crawl into the mesh bag tip by animal and then bag mouth is reinstated line together with animal tail one and tie up, simplify the laboratory animal operation sequence, be fit to unfamiliar student and use.
2. this utility model adopts ventilative nylon material to make, and has guaranteed breathability, and the situation of avoiding animal to suffocate occurs.
3. this utility model dictyosome adopts nylon material to make, and firm and durable can be repeatedly used, and saves experiment material and cost.
Description of drawings
Fig. 1 is this utility model structural representation among the embodiment
Wherein: 1, dictyosome; 2, opening.
The specific embodiment
Below in conjunction with drawings and Examples this utility model is further described:
Embodiment one: referring to shown in Figure 1, a kind of experimental rat class fetters net temporarily, comprises dictyosome 1, and described dictyosome 1 is the taper mesh bag, is provided with opening 2 at the bottom of the described taper mesh bag bag.
Described dictyosome length is 15 centimetres, and opening diameter is 10 centimetres.At 5-10 centimetre, body weight restrains at 15-40 laboratory mice body length generally, selects the constraint net of present embodiment size, is suitable for laboratory mice is fettered temporarily.It is smooth that the size of mesh bag and angle have guaranteed that animal enters mesh bag, but tune is relatively more difficult after entering mesh bag.Owing to be the taper mesh bag, the mesh bag front space is enough narrow and small, guarantees that the upper lower jaw of animal is fixed and can't opens.Mesh bag material selection 400 order nylon materials are not scratched by animal guaranteeing, and guarantee breathability, in order to avoid animal is suffocated.
Concrete operation method of the present utility model is as follows: at first the experimental rat class is fettered net temporarily and open in laboratory table, catch the bag mouth edge of taper mesh bag with left hand, and bag mouth aimed at the animal head, the right hand is caught the animal tail end, animal has the behavioral trait that crawls forward, therefore animal can initiatively climb into mesh bag, and head is extend into the tip of mesh bag always.After animal enters mesh bag, fast bag mouth is reinstated line together with animal tail one and tighten, then just can carry out corresponding experimental implementation.For example carry out lumbar injection, can directly injection needle directly be seen through mesh bag and thrust the animal abdominal cavity.Experiment after finishing is untied bag mouth, and gently animal is hauled out.
Embodiment two: a kind of experimental rat class fetters net temporarily, comprises dictyosome, and described dictyosome is the taper mesh bag, is provided with opening at the bottom of the described taper mesh bag bag.
In the present embodiment, described dictyosome length is 20 centimetres, and the network interface diameter is 15 centimetres.Generally at 10-18 centimetre, body weight restrains at 150-400 with rat body length in experiment, selects the constraint net of present embodiment size, is suitable for experiment is fettered with rat temporarily.
Claims (4)
1. an experimental rat class fetters net temporarily, comprises dictyosome, it is characterized in that: described dictyosome is the taper mesh bag, and described taper mesh bag rear end is provided with opening.
