Description
Technical field
The present invention relates to the Bioexperiment equipment technical field, specifically a kind of low-temperature biological operation bench with purification function.
Background technology
Bioexperiment work has certain particularity, therefore the specification requirement to Bioexperiment equipment is quite strict, it should guarantee that the bacterium and the virus that produce are not leaked in experimentation, guarantee that the environment in the laboratory is not contaminated, avoid operating personnel to be subjected to the infringement of bacterium and virus, also to guarantee to test thing not by suspension in the middle of the external environment condition and particle contamination, not be affected with the quality that guarantees the experiment thing.During especially for the blood packing carried out under low temperature environment, can produce impurity such as aerosol because of blood, and aerosol is a kind of important pollution sources in minute process of assembling, there is the danger that environment and operating personnel is caused easily infringement in it; Simultaneously, blood is subjected to the intrusion of suspension in the environment, particle easily in minute process of assembling, and it can badly influence the quality of blood.Thus, during the blood packing, pollute in the not contaminated source of environment and operating personnel that can either guarantee, can guarantee that again blood not by the suspension in the environment, particle contamination, is that a great problem to be solved is arranged at present.
Chinese patent 200720020778.4 discloses a kind of medical single-side low temperature workbench, because this structure exists not enough, so existence can't fundamentally solve environment and pollute in the not contaminated source of operating personnel, and blood is not by the problem of the suspension in the environment, particle contamination.
Summary of the invention
Purpose of the present invention provides a kind of low-temperature biological operation bench, and it can solve that prior art exists can't fundamentally solve environment and the not contaminated source of operating personnel is polluted, and blood is not by the problem of the suspension in the environment, particle contamination.
Purpose of the present invention is achieved through the following technical solutions: low-temperature biological operation bench, and it comprises stand, stand is provided with table top, connects ventilating duct on the stand, offers air vent on the madial wall of ventilating duct; The ventilating duct left and right sides is installed left deep bead and right deep bead respectively; The stand internal upper part is provided with the blast channel that communicates with ventilating duct; The air blast chamber is set in the blast channel, blower fan is installed in the air blast chamber, the blast orifice of blower fan communicates with blast channel, and evaporimeter and filter are installed respectively in the blast channel; Offer return air hole on the table top, return air hole communicates with the air blast chamber; Evaporimeter is connected with refrigerating plant.
For further realizing purpose of the present invention, also can finish by the following technical programs: described air vent is made up of overdraught hole and inboard air vent, the overdraught hole is opened in before the top of ventilating duct on the madial wall, and inboard air vent is opened on the madial wall of ventilating duct; Described return air hole is opened on the front side of table top.Heat-insulation layer is installed on the ventilating duct.Heat-insulation layer is installed on the blast channel.Display before ventilating duct top front end connects.Refrigerating plant is installed in the stand, and refrigerating plant is made up of refrigeration compressor and condenser, and the evaporimeter refrigerating plant is connected.
The beneficial effect that the present invention can produce: because of in being provided with the blast channel of blower fan, filter being installed, so it can make blood packing produced pollution source, and the suspension in the environment, particle is filtered device by flowing of cold wind and filters, make in the operating space all the time by after filtering purifying gas flow and contain, its pollution sources that can play in the operating space can't leak, and the suspension outside the operating space, the effect that particle can't be invaded, so environment and operating personnel pollute in easy contaminated source when fundamentally having solved the blood packing, and blood in minute process of assembling easily by environment in suspension, the problem of particle contamination;
Because of before the top of ventilating duct, offering the overdraught hole on the madial wall, and on the madial wall of ventilating duct, offer inboard air vent, and on the front side of table top, offer return air hole, return air hole communicates with the air blast chamber, blower fan is installed in the air blast chamber, so during blower fan work, air-flow from the overdraught hole and inboard air vent blow out, get back in the air blast chamber from return air hole, circulate repeatedly with this, formed the regular mobile air curtain that purifies air, it has further contained table top with interior operating space, so further avoided the pollution sources in the operating space to external leakage, further avoided suspension and particle in the external environment of operating space to invade in the operating space, more effectively guaranteed environment and operating personnel's the safety and the quality of blood packing.
The present invention not only has operating environment and personnel's not contaminated source pollution in the time of can guaranteeing the blood packing, and blood in minute process of assembling not by environment in the distinguishing feature of suspension, particle contamination, but also has scientific and reasonable Cryogenic air endless form, it can make well-regulated the flowing that purify air, further contain not outside leakage pollution source, operating space, further prevent the intrusion of suspension and particle, more effectively guaranteed environment and operating personnel's the safety and the quality of blood packing, extensive use can produce good social, economic benefit.
