The reagent preheating device provided by the invention is simple in structure, can be used for heating uniformly and rapidly, is especially suitable for analysis instruments for medical analysis and inspection; reagents are heated up to the preset temperature in advance before entering a reaction site so as to provide a good reaction effect.
Description
Affiliated technical field
The present invention is the pre-warmed device of a kind of reagent; Refer to especially the preheating device for reagent being applied in medical inspection analytical instrument.
Background technology
In medical inspection analytical instrument, particularly, in blood analysis instrument system, need to carry out agent treated to the blood sample in inspiration machine and react with constant-temperature incubation.How simply to realize fast the isothermal reaction of reagent, become a research topic in this field.Solution to this problem was generally before reagent adds reaction tank and first reagent is preheated, and guarantee reagent had reached needed temperature before adding.
The preheating device for reagent of this function has been applied in medical inspection analysis field.Its problem is, reagent used in medical inspection analytical instrument, is generally all the solution that corrosivity is stronger, how to make to preheat the requirement that thermostat can meet corrosion resistance, and can have again good thermal conductivity becomes a difficult problem simultaneously.Disclosed United States Patent (USP) (the patent No.: 6694747) just introduced a kind of like this patent, this patented technology scheme for digging out reagent passage and matrix both sides cover corrosion resistant diaphragm, heat-conducting plate and heating film successively on a matrix.This scheme has solved heat conduction and the corrosion-resistant contradiction to material requirements to a certain extent, but structure is comparatively complicated, also higher to material requirements.
Summary of the invention
Technical matters to be solved by this invention is, overcomes the deficiencies in the prior art, and required reagent is preheated to temperature required.
The technical solution adopted for the present invention to solve the technical problems is: the pre-warmed device of a kind of reagent, comprising: regenerative block, reagent container and heater element or refrigeration device, also comprise cover plate, air locking; Reagent container is positioned among regenerative block, and air locking is enclosed within the two ends of reagent container, and the common crush seal device of the outer wall of reagent container, regenerative block and cover plate is realized the sealing of liquid.
Described regenerative block has the through hole that holds described reagent container, and is clearance fit between described reagent container, fills conduction oil or heat-conducting silicone grease and strengthen heat conduction between its space.Reagent container is drum, and air locking is enclosed within on cylinder outer wall, holds two tops of the through hole of reagent container on regenerative block, has terraced structure, in order to hold described air locking.Described cover plate and described regenerative block are fixed together by the mode of mechanical connection, and push the air locking that regenerative block is topped bar in shape structure, realize sealing.The position of cover plate UNICOM reagent container, has through hole, turnover for liquid.
Described heater element is one to be attached to the membrane type well heater of regenerative block outside.
Described regenerative block is hot good conductor.
Described reagent container is the Circular Thin pipe that corrosion resistance is good and heat conduction is good.
Described cover plate is that the good material of corrosion resistance is made.
The invention has the beneficial effects as follows, utilize feature that Circular Thin pipe has thermal conductive resin and strong corrosion resistant simultaneously using it as reagent container; The sealing that cover plate forms the extruding of air locking with regenerative block also guarantee reagent only contacts cover plate and reagent container.Like this simple in structure, material easily obtains, and also can meet Fast Heating and corrosion resistant requirement.

Embodiment
Below in conjunction with embodiment and accompanying drawing, content of the present invention is described in more detail.
Shown in Fig. 1 to Fig. 3, a kind of embodiment of the present invention comprises: outlet connection 1, upper cover plate 2; Membrane type well heater 3; Lower cover 4; Inlet attack 5; Temperature sensor 6; Overheat switch 7; Reagent container 8; Seal element 9; Screw 10; Regenerative block 11; Terraced structure 12; Outlet opening 13; Ingate 14.
Through hole or groove in the middle of regenerative block 11, have been dug in order to hold reagent container 8, temperature sensor 6 and overheat switch 7.For strengthening the space of heat-transfer effect between regenerative block 11 and reagent container 8, temperature sensor 6 and overheat switch 7, scribble heat-conducting silicone grease to strengthen heat transfer.In the side of regenerative block 11, post membrane type well heater 3, as heater element, provide heat.As mentioned above, membrane type well heater 3 produces heat and provides heat by regenerative block 11 heating, and the heat of regenerative block 11 passes to the reagent of the reagent container 8 of flowing through by reagent container 8.The temperature of temperature sensor 6 monitoring regenerative blocks 11, makes the temperature of regenerative block 11 remain constant.Overheat switch 7 device superheat protecting functions, in temperature sensor 6 inefficacies or other situation, if the temperature of regenerative block 11 surpasses safe range, overheat switch 7 will disconnect the circuit of membrane type well heater 3, stops heating.
In the above-described embodiments, regenerative block plays accumulation of heat heat conduction, adopts the higher metal material of heat transfer coefficient, such as aluminium, copper etc.Reagent container not only needs heat conductivility good, also needs there is stronger reagent corrosion resistance simultaneously, therefore adopts stainless steel or the good heat conducting material after surface treatment.In order to reduce heat to the heat radiation of environment as far as possible, at regenerative block, can also wrap up insulation material around.
By concrete enforcement, describe the present invention above; but the present invention is not limited to this specific embodiment; those skilled in the art should be understood that; can also make various modifications to the present invention, be equal to replacement, change etc.; but as long as do not deviate from spirit of the present invention, all should be within protection scope of the present invention.
