Fig. 1 is that smoke inhalation of the present utility model is caused injury the schematic diagram of experimental provision.
Wherein, 1, lid; 2, cylindrical tube; 3, wire gauze; 4, be fuming room; 5, to cause injury room; 6, container; 7, smoking material; 8, iron pipe; 9, thermometer.
Detailed description of the invention
Detailed description of the invention of the present utility model is described in detail below in conjunction with accompanying drawing.
This utility model relates to a kind of smoke inhalation and to cause injury experimental provision, to cause injury experiment, thus understand smoke inhalation pathogenesis for carrying out mice smoke inhalation.
Fig. 1 shows smoke inhalation of the present utility model and to cause injury the schematic diagram of experimental provision.As shown in Figure 1, smoke inhalation described in the utility model experimental provision of causing injury comprises the cylindrical tube 2 of upper end open and covers the lid 1 of described cylindrical tube 2.Wherein, in order to prevent smog from overflowing from this experimental provision, described lid 1 can arrange sealing device with the junction of described cylindrical tube 1, such as, arrange elastic tape.Can prevent smog from overflowing from the junction of described cylindrical tube 2 and described lid 1 by arranging elastic tape.Described cylindrical tube 2 and described lid 1 can be made up of ferrous material, thus make this experimental provision and cheap, and durable in use.
Wherein, the inside of described cylindrical tube 2 is divided into two-layer up and down by wire gauze 3.It is the room 4 that is fuming at the middle and upper levels, and its volume accounts for 30% of the volume of whole cylindrical tube 1.Lower floor is room 5 of causing injury, and its volume accounts for 70% of the volume of whole cylindrical tube 1.Described wire gauze 3 places container 6.Smoking material 7 is placed, so that produce smog by lighting described smoking material 7 in described container 6.Wherein, preferably, described smoking material is pine sawdust and kerosene mixture.More preferably, described pine sawdust and kerosene mixture are formed by the dry pine sawdust of 50g and 10ml kerosene 10 Homogeneous phase mixing.Adopt the smoking material of this composition, smoke composition of being fuming mainly comprises CO, aldehydes etc., can cause damaging action to mice, is applicable to carrying out this research.In this utility model, the smog of Reality simulation fire is responsible for producing in the room 4 that is fuming, and for placing experiment mice in room 5 of causing injury, makes experiment mice suck the smog produced in the room 4 that is fuming.In this utility model, preferably, the diameter D=25cm of described cylindrical tube 2, high L=55cm.Wherein, the cylindrical tube of this kind of shape and size combines with the above-mentioned volume ratio of be fuming room 4 and room 5 of causing injury, and contributes to making to be similar to real fire hazard aerosol fog situation in whole experimental provision, thus increases the verity of experiment.
Described bottom sides of causing injury room 5 opens an aperture." L " type iron pipe 8 is inserted in this aperture, and at the built-in thermometer 9 of described pipeline 8.By set temperature meter 9, contribute to grasping experiment mice and suck the temperature of causing injury of smog, thus contribute to studying further suction and to cause injury model.In this utility model, preferably, the diameter of described aperture is 1.5cm, described " L, the internal diameter of type iron pipe 8 is 1cm, and longer length is 5cm.Wherein, described " L " type iron pipe 8 inserts in described aperture, and around seals, and prevents smog from overflowing.
Cause injury in experimental provision at smoke inhalation described in the utility model, for the ease of putting in described room 5 of causing injury and taking out experiment mice, described in the cause injury bottom sides of room 5 can also offer unshowned door in a Fig. 1.When needs are put into or take out experiment mice, open this door, and need not lid be opened and take off wire gauze, contribute to the efficiency improving experiment.
Use this practical smoke inhalation cause injury experimental provision carry out mice smoke inhalation cause injury experiment time, often will organize 10 mices and put into lower floor in advance and to cause injury room with 1% pentobarbital sodium is postanesthetic, smoking material is inserted in container, evenly pave, light, after burning 1min, knock down the flame, material starts to glow, and puts into rapidly upper strata and to be fuming room, airtight lid.Thermometer display causes injury temperature between 35-38 DEG C.Start time of the causing injury timing according to setting, fixed point takes out mice, is placed in ventilation, recovery.After wound, mice freely takes in drinking water, the situation of observation experiment mice.
The content of detailed description of the invention is understood for the ease of those skilled in the art and uses this utility model and describe, and does not form the restriction to this utility model protection content.Those skilled in the art, after having read content of the present utility model, can carry out suitable amendment to this utility model.Protection content of the present utility model is as the criterion with the content of claim.When not departing from flesh and blood and the protection domain of claim, the various amendments carried out this utility model, change and replacement etc. are all within protection domain of the present utility model.
