Embodiment
Below by embodiment, and with reference to accompanying drawing, the technical solution of the utility model is described in further detail.
Embodiment：A kind of contactless water bath device of the utility model, as shown in accompanying drawing 1, accompanying drawing 2, it includes：Water bath bag
1 and liquid processing system.
Water bath bag 1, there is the soft bag that can wrap test tube to be heated to be heated to test tube；Bag body is situated between for that can deposit liquid
The enclosed construction of matter, the inlet and outlet of output body is entered with medium for liquid.
Liquid processing system, heated with liquid medium and the liquid medium of heating is conveyed to water bath bag.Liquid handling
System includes：Water tank 2, pump 5 and control loop.Water tank 2, for housing and heating liquid medium, built-in Temperature controlled heater 3 and temperature
Spend sensor 4.Pump 5, the described water tank 2 of its import connection, outlet connect the import of the water bath bag 1.Control loop, including
Link circuit, the outlet of water bath bag 1 and the link circuit of water tank 2 that the import of water bath bag 1 exports with pump 5；Pump 5 and the company of water bath bag 1
First stop valve 6 is set on adapter road, and the first stop valve 6 connects first of water tank 2 with the setting on the connecting line of pump 5
Road, the second stop valve 7 is set in tie point；The import of pump 5 is with setting the 3rd stop valve 8 on the connecting line of water tank 2；Water bath bag
1 with setting the 4th stop valve 9 on the connecting line of water tank 2, the is set on connecting line of the 4th stop valve 9 with water bath bag 1
Two branch roads, the 5th stop valve 10, the connecting tube of the stop valve 8 of end connection the 3rd and pump 5 of the second branch road are set on second branch road
Road.
Heating is in use, as shown in Figure 1, the first stop valve 6, the 3rd stop valve 8 and the 4th stop valve 9 being entered and turned on
State, the second stop valve 7 and the 5th stop valve 10 enter by state；Intermittent start Temperature controlled heater 3, in heating water tank 2
Liquid medium reach and maintain default temperature；Start pump 5, liquid medium is delivered to water bath bag 1,1 bag of body of water bath bag
Open, outlet of the liquid medium through water bath bag 1 is expelled to water tank 2, and 1 bag of body of water bath bag maintains under the liquid medium effect of flowing
In constant operating temperature；Test tube to be heated is abutted on the bag body of water bath bag 1 and heated.
During non-working condition, as shown in Figure 2, draining, draining back pkt. body Temperature fall, to suppress are carried out to water bath bag 1
Bacterial growth on bag body；First stop valve 6, the 3rd stop valve 8 and the 4th stop valve 9 are entered by state, the second stop valve 7
Enter conducting state with the 5th stop valve 10；Start pump 5, the liquid medium in water bath bag 1 is evacuated, 1 bag of body of water bath bag enters
Collapse state.Water bath bag emptying reduces moisture, has contained the growth of bacterium on bag body；Meanwhile after draining, bag temperature declines,
It further suppress the bacterial growth on bag body.
The bag body of water bath bag 1 is changeability structure, is in flat during nature, is swelled in middle part during internal-filling liquid body medium
Swelling state；During swelling state, test tube to be heated is placed on bag body, under the Action of Gravity Field of external force or test tube to be heated,
The periphery wall of bag body sidewall wrapping test tube.
Described in Pass through above-mentioned technical proposal, the utility model has the following advantages that.
1st, 1 bag of body of water bath bag of test tube is heated, it is easier to which sterilization treatment is done to its surface.
2nd, test tube is heated using the bag body of sealing, contact surface is big, is not easy to form local heating to test tube, is heated more
It is balanced.
3rd, liquid medium heats in advance in the larger water tank of volume, and heat can carry out sufficient heat transfer, due to not
Directly heated in the water bath bag of small volume, make the temperature of liquid medium more stable, be not in each position in water bath bag
The phenomenon that liquid medium temperature differs.
4th, in heating, liquid medium enters, from the outlet stream of water bath bag in the presence of pump from the import of water bath bag
Go out, the liquid medium in water bath bag is in flow regime all the time, the heat for heating test tube and being lost in, obtains timely, quick benefit
Fill, the temperature of water bath bag bag body is more accurately maintained in operating temperature, there is preferable constant temperature effect.
It should be understood that description above is only the example of the preferred embodiment of the present invention.Those skilled in the art can
Made various changes and modifications in the case where not departing from the utility model.Thus, the utility model is intended to include falling in right
All these replacements in claimed range, modifications and variations.
