Description
Technical field
The utility model is related to a kind of blood analyser, more particularly to a kind of blood cell analyzer and its reaction tank
Temperature control equipment.
Background technology
Clinical examination instrument, such as cellanalyzer, more particularly to a kind of white blood cell count(WBC) is with leukocyte differential count test altogether
With a cellanalyzer for reaction tank.In leukocyte differential count test, generally need to locate blood in advance
Reason, is reacted using specific reagent and blood, while to ensure that reaction fully, can be carried out reliably, it is necessary to give reaction
Place provides an isoperibol for stabilization.It is widely used in cellanalyzer to realize (30~40 DEG C) reactions of reagent constant temperature
Method be that reagent is preheated, make reagent add reaction tank before reach needed for temperature.Such as patent CN201320862224
Including regenerative block, reagent container, heater element, cover plate, air locking etc., reagent container is located at the preheating device for reagent mentioned
Among regenerative block, air locking is enclosed within the two ends of reagent container, and the outer wall of reagent container, heat storage pool and cover plate extrude close jointly
Envelope device realizes the sealing of liquid, ensure that reagent is preheated to required temperature before reaction tank is added.But aforesaid way, deposits
In following problem, i.e., when the reagent of preheating is added to reaction tank, because the temperature of reaction tank is different from temperature of reagent, can cause
Add warmed-up reagent temperature produce change, when particularly instrument is used at low ambient temperatures, reaction tank with add
Temperature of reagent differs greatly, and the temperature of reagent for adding can be caused to decline obvious, and now the temperature change of reagent can be beyond pretreatment
Required steady temperature scope is reacted, the stability of apparatus measures is influenceed.Accordingly, it would be desirable to a kind of thermostatic control mode is maintained
Reaction tank is in the temperature environment of constant (30~40 DEG C), it is to avoid reaction tank in itself try adding by (particularly less than 25 DEG C of room temperature)
The temperature of agent is impacted.
Do not have any scheme at present carries out thermostatic control for the reaction tank to such cellanalyzer, is simply related to
To preheating device for reagent.

The corrosion-resistant preferable titanium alloy of effect of reagent is made, and the preheating flow channel of reagent is built in body, and reagent flow is preheated
Passage is heated, although can reach the purpose of reagent preheating and reaction environment constant temperature, but the integrated preheating device is pin
Reaction tank design to leukocyte differential count, it is impossible to used with the pond of two kinds of functions with counting as leukocytoreaction, it is impossible to
It is applied in such cellanalyzer, is unfavorable for realizing the Highgrade integration of instrument；And preheating channel is made using titanium alloy,
Processing difficulties, device is complicated, high cost.For another example the leukocyte differential count incubating device that patent CN201610025457 is mentioned is one
Formula preheat incubating device, the body using aluminium alloy make, pipe laying groove is machined with body, to imbed pipeline in the way of give
The small reagent of consumption is directly preheated, and front preheating process is carried out to the big reagent of consumption.In addition using the insulation that 5mm is thick outside incubating device
Cotton coats, and reduces external heat loss.Although being easier to processing than aforementioned patent body, device is equally complicated, can not be simultaneous
Hold for white blood cell count(WBC) function.All such integral type reagents preheating incubating devices can not compatible white blood cell count(WBC) function,
It is unfavorable for the Highgrade integration of instrument, and apparatus structure is complicated, high cost.
Therefore, prior art has yet to be improved and developed.
