Specific embodiment
Below with reference to the embodiments and with reference to the accompanying drawing the technical solutions of the present invention will be further described.
Embodiment: a kind of contactless water bath device of the present invention, as shown in attached drawing 1, attached drawing 2 comprising: 1 He of water bath bag
Liquid processing system.
Water bath bag 1 has the soft bag that can wrap test tube to be heated to heat to test tube；Bag body is that can store liquid Jie
The enclosed construction of matter has the inlet and outlet for liquid medium disengaging bag body.
Liquid processing system, to be heated to 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 accommodating and heating liquid medium, built-in Temperature controlled heater 3 and temperature
Spend sensor 4.Pump 5, the import connection water tank 2, outlet connect the import of the water bath bag 1.Control loop, including
The link circuit of 5 outlet of 1 import of water bath bag and pump, water bath bag 1 export the link circuit with water tank 2；The company of pump 5 and water bath bag 1
First of setting connection water tank 2 on the connecting line of the first shut-off valve 6 of adapter tube road setting, the first shut-off valve 6 and pump 5
The second shut-off valve 7 is arranged in the first branch in road；It pumps and third shut-off valve 8 is set on the connecting line of 5 imports and water tank 2；Water bath bag
1 with the 4th shut-off valve 9 is set on the connecting line of water tank 2, the is arranged on the 4th shut-off valve 9 and the connecting line of water bath bag 1
The 5th shut-off valve 10, the connecting tube of end the connection third shut-off valve 8 and pump 5 of second branch are arranged in second branch for two branches
Road.
Heating is in use, as shown in Fig. 1, the first shut-off valve 6, third shut-off valve 8 and the 4th shut-off valve 9 being entered and are connected
State, the second shut-off valve 7 and the 5th shut-off valve 10 enter by state；Intermittent start Temperature controlled heater 3, in heating water tank 2
Liquid medium reach and maintain preset temperature；Starting pump 5, is delivered to water bath bag 1,1 bag body of water bath bag for liquid medium
It opens, liquid medium is expelled to water tank 2 through the outlet of water bath bag 1, and 1 bag body of water bath bag maintains under the liquid medium effect of flowing
In constant operating temperature；Test tube to be heated is sticked in the bag body of water bath bag 1 and is heated.
When non-working condition, as shown in Fig. 2, water bath bag 1 is drained, bag body Temperature fall after draining, to inhibit
Bacterial growth in bag body；First shut-off valve 6, third shut-off valve 8 and the 4th shut-off valve 9 are entered by state, the second shut-off valve 7
Enter on state with the 5th shut-off valve 10；Starting pump 5, the liquid medium in water bath bag 1 is evacuated, and 1 bag body of water bath bag enters
Collapse state.Water bath bag emptying reduces moisture, has contained the growth of bacterium in bag body；Meanwhile after draining, the decline of bag body temperature,
Further suppress the bacterial growth in bag body.
The bag body of water bath bag 1 is changeability structure, and in flat when nature, when internal-filling liquid body medium swells in middle part
Swelling state；When swelling state, test tube to be heated is placed in bag body, under the gravity of external force or test tube to be heated,
The periphery wall of bag body side wall wrapping test tube.
It is described through the above technical solution, the invention has the advantages that.
1,1 bag body of water bath bag of test tube is heated, it is easier to which sterilization treatment is done to its surface.
2, test tube is heated using the bag body of sealing, contact surface is big, is not easy to form local heating to test tube, be heated more
It is balanced.
3, liquid medium heats in advance in the biggish water tank of volume, and heat can carry out adequately heat transmitting, due to not
It is directly heated in the water bath bag of small volume, keeps the temperature of liquid medium more stable, be not in each position in water bath bag
The different phenomenon of liquid medium temperature.
4, when heated, liquid medium is under the action of pump, enters from the import of water bath bag, from the outlet stream of water bath bag
Out, the liquid medium in water bath bag is in flow regime always, heats test tube and the heat that is lost, can be obtained timely, quick
Supplement, maintains the temperature of water bath bag bag body more accurately in operating temperature, has preferable constant temperature effect.
It is presently considered to most practical and preferred embodiment although having been combined invention has been described, it can
With understanding, invention is not limited to the disclosed embodiments and element, on the contrary, it is intended to cover including in appended power
Combination, equivalent device and the equivalent element of various remodeling, feature within the spirit and scope of sharp claim.Therefore,
