Abstract
The utility model relates to an anoxia experimental facility, which is mainly composed of an anoxia room and a thermostatic groove. The anoxia room is a dome with a square bottom and is arranged in the thermostatic groove. The temperature of an experimental environment in the anoxia room is ensured through the thermostatic groove. A working window, an oxygen measuring hole, an air inlet connector, wherein, the base of which has an eight-hole structure and an air outlet connector are arranged in the anoxia room. No dead air space exists in the whole anoxia room. Gas led into the anoxia room has the advantages of good dissemination, even oxygen concentration, slow and smooth airflow, and small gas consumption. Thus, the requirement of animal experiments in a hypoxia environment can be met.
Description
A kind of anoxic experimental provision relates to medical experimental provision manufacturing technology.
Perinatal asphyxia causes the damage of fetal brain Hypoxia and ischemia for the maximum common disease of neonatal period harm, often causes the serious sequelae of neonatal death and survivor.For the pathogenesis to the cerebral anoxia ischemic injuries has definite understanding, brainstrust utilizes the neonate rat research that experimentizes under anoxia condition, and hypoxia device then is the key of carrying out this research.Report was abroad once arranged, and the anoxic experimental provision is that the large size syringe is transformed into the anoxic cabin that the rear end is open, place single neonate rat.Though this anoxic cabin is simple in structure, neonate rat activity in this narrow space is obviously limited, and air-flow is steady inadequately in the cabin, and air consumption is big, cause the hypoxemia experimental situation not guarantee, so experimental result is not ideal enough.The domestic report that yet there are no this respect so far.
The purpose of this utility model is: for the anoxic experimental study provides a kind of simple and reasonable, easy and safe to operate, and the reliable anoxic experimental provision of experimental result.
The utility model mainly is made of anoxic chamber and thermostat, and anoxic chamber is placed in the thermostat.Anoxic chamber adopts transparent material to make the end, the side of being vault.Its inlet suction port, air outlet adapter and working window are located at the anoxic chamber end walls respectively, and inlet suction port and air outlet adapter are not located on the same horizontal line.The base of inlet, outlet joint is eight-pore structure, is convenient to enter the interior gas of anoxic chamber to disperse all around.Be provided with mini fan in the anoxic chamber, can stir the gas that enters in the room, make in the room gas concentration tend to consistent as early as possible.Top at anoxic chamber is provided with oxygen measuring pore.Thermostat adopts the electric heating constant temperature water bath, and required temperature environment when thermostat can guarantee the anoxic experiment can be carried out experiment smoothly.
The utility model has the advantages that: anoxic chamber employing side end vault construction, can avoid gas dead space in the room as far as possible.Inlet suction port and air outlet adapter are not located on the same horizontal line, and its base is an eight-pore structure, the gas that enters in the anoxic chamber can be to eight direction disperses, make the gas concentration in the whole room even, gas can constantly be upgraded everywhere, and flows out to venthole straight after having avoided gas to enter anoxic chamber.Be provided with mini fan in the anoxic chamber, in gas entered the room, mini fan open to stir air, made that gas concentration tends to unanimity fast in the room in, had shortened the preparatory stage of anaerobic environment.Therefore, gas concentration is even in the anoxic chamber, and air-flow is steady, gentle, smooth and easy, and the experiment air consumption is little.
Accompanying drawing is the utility model embodiment, in conjunction with the accompanying drawings the utility model is further described.
The utility model is mainly by anoxic chamber (1), and thermostat (10) constitutes.On the end walls of anoxic chamber (1), be respectively equipped with inlet suction port (7) and air outlet adapter (3).The base of inlet suction port (7) and air outlet adapter (3) is eight-pore structure (6), (2).The position of air outlet adapter (3) is higher than inlet suction port (7).Blower tray (9) is arranged on the below of inlet suction port (7), and mini fan (8) is fixedly mounted on the blower tray (9).Working window (4) is located at the below of air outlet adapter (3), covers as window with the screw thread spiral cover that has valve rubber, and open and close is convenient, good seal performance.Oxygen measuring pore (5) is located at the top of anoxic chamber, and O type rubber seal is arranged in the oxygen measuring pore (5), can prevent that the interior gas of anoxic chamber (1) from being leaked by bypass.The oxygen analyser probe enters in the anoxic chamber by oxygen measuring pore (5), can test just or test overall process and measure oxygen concentration at any time.Thermostat (10) adopts the electric heating constant temperature water bath, water saving that the knob on the thermostat control panel (11) is adjustable temperature, and to obtain environment temperature in the desired anoxic chamber of experiment, the assurance experiment is carried out smoothly.
During experiment, anoxic chamber (1) is placed in the thermostat (10), and the environment temperature in the anoxic chamber (1) is given security by thermostat (10).Low concentration oxygen is by appendix disperse from all directions in the room by inlet suction port (7) and eight-pore structure (6), and mini fan (8) stirs the gas that enters in the room, and the gas concentration in the room is reached unanimity as early as possible, and gas concentration is even.It is interior with the oxygen concentration in the mensuration room that the oxygen analyser probe inserts anoxic chamber (1) from oxygen measuring pore (5), or at the omnidistance oxygen determination in real time of experiment.Gas in the anoxic chamber (1) communicates with atmosphere after air outlet adapter (3) is delivered to water-sealed drainage bottle by appendix from eight directions, when treating that interior oxygen concentration of anoxic chamber (1) and environment temperature reach requirement of experiment, can open working window (4), put into animal used as test and carry out the anoxic experimental study.
Claims (1)
1, a kind of anoxic experimental provision, comprise anoxic chamber (1), thermostat (10), it is characterized in that: anoxic chamber (1) end, the side of being vault, inlet suction port (7), air outlet adapter (3) and working window (4) are located on the end walls of anoxic chamber (1), and the base of inlet suction port (7) and air outlet adapter (3) is an eight-pore structure (6,2), oxygen measuring pore (5) is located at the top of anoxic chamber (1), and blower tray (9) is located at the below of inlet suction port (7) in the anoxic chamber, and fan (8) is fixed on the blower tray (9).
