Description
Technical field
The present invention relates to the Bioexperiment equipment technical field, specifically a kind of two-sided 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 200720019382.8 discloses a kind of medical two-sided 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 two-sided 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: two-sided low-temperature biological operation bench, and it comprises stand, stand is provided with table top, and ventilating duct is installed on the stand, offers air vent on the madial wall of ventilating duct; Both sides are installed deep bead respectively before and after the ventilating duct; The stand internal upper part is provided with blast channel, and blast channel communicates with ventilating duct; Forward and backward two ends are provided with preceding air blast chamber and air blast chamber, back respectively in the blast channel, and first blower fan is installed in the preceding air blast chamber, and second blower fan is installed in the back air blast chamber, and the mutual correspondence of the blast orifice of first blower fan and second blower fan also communicates with blast channel respectively; First filter and second filter are installed respectively in the blast channel, and first filter is corresponding with the blast orifice of first blower fan, and second filter is corresponding with the blast orifice of second blower fan; Return air hole and back return air hole before the both sides, front and back of table top are offered respectively, preceding return air hole communicates with preceding air blast chamber, and back return air hole communicates with air blast chamber, back; Evaporimeter is installed in the blast channel, and evaporimeter is connected with refrigerating plant.
Be further to realize purpose of the present invention, also can finish by the following technical programs: described air vent by the top of at least one before air vent, rear venting hole, top, left air vent, right air vent form; The front end of ventilating duct upper inner wall is offered air vent before the top, rear venting hole, top is offered in the rear end, offers on left air vent, the Right Inboard wall on the madial wall of a ventilating duct left side and offers right air vent.
On the described ventilating duct heat-insulation layer is installed.Heat-insulation layer is installed on the blast channel.
Display, rear end connected the back display before ventilating duct top front end connected.
Refrigerating plant is installed in the stand, and refrigerating plant is made up of refrigeration compressor and condenser, and evaporimeter is connected with refrigerating plant.
The beneficial effect that the present invention can produce: because of filter is installed in blast channel, filter is corresponding with the blast orifice of blower fan, 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;
Cause is air vent before the front end of the upper inner wall of ventilating duct is offered top, rear venting hole, top is offered in the rear end, and in blast channel before, air blast chamber and air blast chamber, back before back two ends are provided with respectively, and before the both sides, front and back of table top are offered respectively return air hole and the back return air hole, preceding return air hole, back return air hole respectively with preceding air blast chamber, back air blast chamber communicates, so first blower fan, during the work of second blower fan, air-flow air vent before the top, rear venting hole, top blows out downwards, the past return air hole, back return air hole is got back in preceding air blast chamber and the air blast chamber, back, circulate repeatedly with this, formed the regular mobile air curtain that purifies air, it has further effectively contained table top with interior operating space, so further avoided the pollution sources in the operating space to external leakage, further avoid 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 in the time of can guaranteeing the blood packing the not contaminated source of operating environment and personnel and pollutes, 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 effectively contain not outside leakage pollution source, operating space, further effectively 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.
