Description

Thawing equipment for frozen blood products

Technical field

The present invention relates to a kind of medical equipment, the frozen blood preparation of hospital, blood bank is carried out the device of quick-thawing, particularly a kind of field operations blood station, medical aid station, field hospital or great disaster scene of being adapted at guarantees the thawing equipment for frozen blood products that the regular supply of first aid blood energy is used.

Background technology

Present various big hospital, blood bank, the employed FP of the R﹠D institution case that thaws, also mostly be the cabinet type machine that lands, not only volume is big, Heavy Weight, move use inconvenient, also water consumption is big, power consumption is high, and the case that thaws also adopts traditional circulator bath method, need water preheat to 40 ℃ just can be thawed, it is long therefore to operate required time, also needs simultaneously manually the plasma bags speed that acceleration thaws of overturning.

The patent No. 200720139250.9 " FP thaw case ", a kind of volume is little, water is few, in light weight, the low desktop computer of being convenient to operate of energy consumption though also provide, and it still adopts general electric heater to the heater of water heating usefulness, and the operating time is long.

The patent No. 200720005830.9 " blood plasma thawing instrument ", in water tank or water tank around heater is housed, can melt automatically evenly by instructions for use, need not manual operation and guarantee that blood plasma melts quality, but its heater still be general electric heater.

Summary of the invention

Technical problem to be solved by this invention is: a kind of thawing equipment for frozen blood products is provided, can directly launch to use and need not preheating, save time and melt thawing rate automatically fast, its multiple functional, mobility strong, guarantee the blood product quality of thawing, the blood product that thaws is provided when being specially adapted to field hospital, great disaster field first aid fast.

The present invention addresses the above problem the technical scheme that is adopted, thawing equipment for frozen blood products, comprise and be connected with door with handles, in the casing of side cover plate, the stove that thaws is installed, box thaws, heater, automatic control equipment, described heater is that magnetron is a microwave generator, the described stove that thaws is the microwave thawing stove, the described box that thaws is to be installed in the microwave thawing box on the rotatable rotating disk in the microwave thawing stove, and the motor in rotating disk and the casing is connected, described automatic control equipment is infrared thermometry probe and intelligent temperature controller and electric controling element, by the button on control circuit and magnetron and the casing guidance panel, the infrared temperature table, timer, ammeter, indicator light connects.

Compared with prior art, 1), this thawing apparatus makes heater because of having adopted magnetron the invention has the advantages that:, replace the traditional water bath method with microwave-hydrothermal method, so it just can be worked after arriving predetermined ground at once, therefore need not preheating, saved preheating time, six bags of blood products are placed in the microwave thawing box, only just can thaw with eight minutes, thawing rate is quick; 2), also can thaw rapidly frozen red cells, blood platelet, blood plasma, accomplishing to rescue the wounded needs anything what just is provided, and has improved the health support ability greatly; 3), also be furnished with power autonomously, under the situation of no external power supply, can work 30 minutes, can shift mobility strong, portable convenience at any time according to the needs of battlefield, field work first aid; 4), adopt infrared thermometry probe and intelligent temperature controller, measure, the control precision height, guarantee that thaw point regulates automatically in safe range, thereby guaranteed the quality of thawing of blood product; 5), an available magnetron also can use two magnetrons simultaneously as required, the microwave stepping is adjustable and timing function is arranged, and uses flexibly, convenient; 6), this device only needs to steep blood product with water logging in the microwave thawing box, omitted recirculated water, required microwave input power is low, therefore energy-conservation water-saving again; 7), this device is particularly suitable for being configured in the field operations blood station, teacher of the satisfying medical aid station, field hospital and base hospital, great disaster scene, the blood supply of assurance first aid, the treatment rate at raising battlefield, scene; 8), adopted multinomial safety precautions, therefore safe in utilization.

Embodiment

Below in conjunction with accompanying drawing embodiments of the invention are further described.

The dividing plate that casing 8 usefulness have through hole is separated into left and right chamber; chamber, a left side is divided into upper and lower chamber with dividing plate 21; epicoele is a microwave thawing stove 9; motor 5 is installed in the cavity of resorption; on the outer top edge of cavity of resorption touch switch 20 is arranged; make the door 3 of microwave thawing stove have power-off protection function, guarantee that microwave thawing stove 9 is safe in utilization.

In the right chamber magnetron 23 being installed is microwave generator and automatic control equipment, surface, right chamber is a guidance panel, on have microwave to drive button 13, microwave to close button 15, indicator light 12, infrared temperature table 19, timer 18, knocker 10, ammeter 17, rotating disk button 14, danger button 16 and total power switch 22, the side cover plate 11 with louvre is screwed on the surface in casing 8 right chambeies in addition.

Casing 8 usefulness corrosion resistant plates are processed into, and handle through hardening oxidation on the surface, has higher impact resistance and corrosion resistance.

Transparency window is arranged in the middle of the outer surface of door 3, inner surface is the middle metal shielding board that uniform small through hole is arranged, small through hole on it is convenient to observe microwave thawing box 6 over against transparency window, between the inside and outside surface of door is cavity, there is Contact plate 2 below of door 3, door limit jug 1, door 3 is hinged on casing 8 epicoele positions.

Put the microwave thawing box 6 that overall plastic structure is arranged on the rotating disk 4, microwave thawing box 6 is complementary with rotating disk 4 shape sizes, the centre has uniform dividing plate to be separated into six lattice, can place water and six bags of blood products 7 thawings simultaneously, be screwed the backing plate 30 of band three-jaw groove in the middle of the lower surface of rotating disk 4, the microwave thawing box is placed on the rotating rotating disk 4, and it is more even that heating member is heated in heating process.

Be fixed with the contiguous block 29 of three claw types on the casing 8 epicoele bottom surfaces, 5 in motor, the three-jaw groove on the rotating disk bottom surface backing plate 30 is held on the contiguous block 29, and rotating disk 4, motor 5 are connected into rotating one.
