Abstract
The utility model belongs to the technical field of medical animal experiments, and particularly relates to a rat fumigating device comprising a glass chest and a stainless steel cage. Two skew symmetric breathing holes and two smoke holes are formed on the left side and the right side of the glass chest in the positions near to the bottom respectively, an extractable chest cover is arranged on the glass chest, a smoke venting hole is formed above the glass chest cover, and the position and size of the smoke venting hole conform to the requirements of concentration and oxygen content of the smog in the chest body; and a spacing mesh arranged in the stainless steel cage divides the stainless steel cage into two parts. The rat fumigating device has the advantages of simple structure, simplicity and convenience in operation, low cost, higher experimental efficiency, and suitability for animal model manufacturing in a laboratory.
Description
Technical field
This utility model belongs to the medical animal experiment technical field, is specifically related to a kind of novel mouse sootiness device.
Background technology
Use the sootiness stimulus method at present and can make several animal models, as chronic bronchitis animal model, emphysema animal model, chronic obstructive pulmonary disease (COPD) animal model, bringing out property pulmonary carcinoma animal model, traditional Chinese medical science syndrome of deficiency of lung qi animal model etc.The self-control sootiness device that is used for the animal model making in the bibliographical information is mainly based on rat at present, and these sootiness devices mainly contain following two kinds of forms: (1) makes airtight Smoke fumigating box by oneself; (2) leave the self-control Smoke fumigating box of passage.
There is following problem in above-mentioned sootiness device: (1) because the body weight size of mice and rat, all variant to each side such as smoke cured tolerations, these Smoke fumigating boxs are not suitable for the making of mouse model; (2) because passage is provided with position and difference in size difference, can not accurately control the smokescope in the casing, cause the homogeneity of animal model different and repeatable poor; (3) because cigarette combustion and animal breath all consume oxygen, the oxygen content in the Smoke fumigating box can not be controlled, and easily causes animal death by suffocation; (4) material of a lot of Smoke fumigating boxs is a lucite, is not suitable for high temperature sterilize.
Summary of the invention
This utility model mice sootiness device technical problem to be solved mainly provides, and a kind of controllability is good, the smokescope during the experiment mice sootiness and oxygen content is stable, but the mice physiological function is disturbed little, reusable autoclave sterilization sterilization, is applicable to that the sootiness stimulus method makes the sootiness device of mouse model.
In order to solve the problems of the technologies described above, the mice sootiness device that this utility model provides is made up of glass box and the Rotating Stainless Steel Cage that is shelved in the glass box; Nearly bottom, the described glass box left and right sides respectively is provided with two antisymmetric passages and two smoke-putting holes (be convenient placement medicated cigarette, the diameter of design smoke-putting hole is consistent with the diameter of medicated cigarette); Described glass box is provided with a drawing and pulling type glass case lid, and the glass box side of covering is provided with an exhaust smoke hole; Be provided with a longitudinal separation net in the middle of the described Rotating Stainless Steel Cage, Rotating Stainless Steel Cage is divided into left and right sides two parts.
In this utility model, the requirement of interior smokescope of casing and oxygen content is satisfied in described exhaust smoke hole size and position, generally maintains about 20% at the intravital oxygen content of sootiness process raising middle flask.
In this utility model, glass box apart from bottom 5--8cm place, left and right sides wall respectively is provided with two metal screw supports, is used to place Rotating Stainless Steel Cage, makes mice and medicated cigarette in the Rotating Stainless Steel Cage spatially have certain distance, in case animal is scalded.
In this utility model, described Rotating Stainless Steel Cage is made of rustless steel, and the Rotating Stainless Steel Cage top is provided with the cage lid.Spacer web is set in the middle of the Rotating Stainless Steel Cage, and two groups of mices of sootiness (about 20) to improve conventional efficient, guarantee the homogeneity of experiment condition between two groups simultaneously simultaneously.
Advantage of the present utility model is, and is easy and simple to handle, with low cost, can improve conventional efficient, is applicable to that laboratory uses.

The specific embodiment
The utility model is described in further detail below in conjunction with Figure of description.
Shown in Fig. 1-6, this utility model comprises glass box 1 and Rotating Stainless Steel Cage 7 two parts, and wherein nearly bottom, the left and right sides of glass box 1 respectively is provided with two antisymmetric passages 3 and smoke-putting hole 2; Be provided with the staple 5 that supports Rotating Stainless Steel Cage in addition on the glass box sidewall, glass box lid 6 is drawing and pulling type, and is easy to operate.Glass box lid 6 is provided with exhaust smoke hole 4.Be provided with a vertical filter 10,2 parts about Rotating Stainless Steel Cage 7 is divided in the middle of the Rotating Stainless Steel Cage 7.Rotating Stainless Steel Cage lid 8 usefulness one carbine 9 is fixed on the sidewall of Rotating Stainless Steel Cage 7.Rotating Stainless Steel Cage 7 is provided with a handle 11, gets so that carry.
During use two groups of mices (10 every group) are put into autoclaved Rotating Stainless Steel Cage, cover cage lid 8, and with metal spring hook 9 fixedly cage cover 8, in case mice escapes from.Open the lid 6 of glass box 1, the Rotating Stainless Steel Cage 7 that mice is housed is placed on the support of the medial wall, the left and right sides in the glass box, cover glass box lid 6.Two medicated cigarettes of lighting are placed the smoke-putting hole 2 of the glass box left and right sides, make its spontaneous combustion, sootiness stimulated after 10-15 minute, and glass box lid 6 is opened, and took out Rotating Stainless Steel Cage 7, at last mice was taken out.Glass box and Rotating Stainless Steel Cage are carried out autoclaving, oven dry, for future use.
Be raw material with glass and stainless steel silk in the present embodiment, cheap, preparation technology is simple, help large-scale production processing, and embodiment is easy and simple to handle, can help increasing work efficiency simultaneously with two groups of mices of a Smoke fumigating box sootiness.
In addition to the implementation, this utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation form, all drop on the protection domain of claim of the present utility model.
