Abstract
The invention discloses a heater used for magnetic bead capture instrument, which comprises a disc which is uniformly provided with slots on the circumference. Hot blocks are arranged in certain slots; and close heat conducting blocks, heating device and radiating fins are tightly fit on the disc and below the hot blocks in sequence. During heating, reagent plates filled with a biochemical reaction reagent are placed on the hot blocks and the heating device are powered on; then the heat generated by the heating devices is transferred on the reagent plates by the heat conducting blocks and the hot blocks in sequence; the radiating fins are fixed below the heating devices; and the heating devices can more quickly transfer heat with the air through the radiating fins; the disc can rotate to drive a heating part and a heat transfer part fixed on the disc to rotate together; in this way, the reagent plates can be under a constant heating state no matter on which position the disc is stayed; therefore, operations can be implemented on other reagent plates on the disc simultaneously when heating, thus realizing automatic working process with high efficiency and high flux, and improving the working efficiency to a great extent. The heater used for magnetic bead capture instrument has the advantages of simple structure, small size and low cost.
Description
Technical field
The present invention relates to the heater field, particularly relate to a kind of heater that is used for the magnetic capture instrument.
Background technology
The existing heater that is used for biochemical reaction is broadly divided into following two kinds:
1, heater is fixed;
2, heater is that a direction or a plurality of direction straight line move.
The heater of these two kinds of biochemical reactions all has certain defective: first kind of heater underaction, if will realize automation and high flux, and having relatively high expectations then to other parts.Though second kind of heater can move in to a certain degree, have certain flexibility, but this Design of device cost and production cost are higher, control is complicated, and occupation space is bigger, and movably scope can only be confined to the rectilinear motion of one or several direction.
Summary of the invention
Technical problem to be solved by this invention be at install in the prior art underaction, complex structure, cost higher, take up room bigger, be difficult to realize automation and high-throughout shortcoming, and a kind of heater that is used for biochemical reaction that rotates that proposes.Device of the present invention can rotate arbitrarily in 360 ° of circumference range, can realize automation, high flux, reaches high efficiency requirement.
The technical problem that the present invention requires to solve can be achieved through the following technical solutions:
A kind of heater that is used for the magnetic capture instrument comprises heater element, hot piece, heat-conducting block, disk; Be evenly equipped with groove on the circumference of described disk, wherein have at least a groove that heating function is arranged, place agent plate in the groove, between described trench bottom that heating function arranged and agent plate, place hot piece, lower disk surface, the position corresponding with groove be heat-conducting block fixedly, described heat-conducting block below fixed heater spare, described disk can together rotate around disc centre with hot piece, heat-conducting block, the heater element fixed on it, so that disk can be in arbitrary position heating of 360 ° of circumference.
Described heater element is settled fin down, and heater element upper surface and heat-conducting block are fitted, and lower surface and fin are fitted, and described heat-conducting block, heater element, fin are fixed together by press strip.
Described heat-conducting block and hot piece are fitted.
The upper surface of described hot piece matches with the shape of agent plate lower surface, contacts with the agent plate maximum area to guarantee hot piece.
Owing to adopted technique scheme, the present invention compared with prior art has following characteristics: the present invention can realize the automation and the high flux of biochemical reaction, thereby greatly increase work efficiency, and device volume of the present invention is little, it is little to take up room, simple in structure, low cost of manufacture.

Fig. 1 is a fragmentary sectional elevation view of the present invention.
Fig. 2 is a front view of the present invention.
Fig. 3 is a upward view of the present invention.
Fig. 4 is a vertical view of the present invention.
Among the figure, 1-heater element, 2-fin, 3-agent plate, the hot piece of 4-, 5-disk, 6-heat-conducting block, 7-press strip.
The specific embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.
As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, the upper surface of heater element 1 and heat-conducting block 6 fitted, and heat-conducting block 6 is fitted with hot piece 4, by heat-conducting block 6 the hot piece 4 of heat transferred of heater element 1 generation.Be evenly equipped with some grooves on the excircle of disk 5, hot piece 4 is placed in wherein the groove, and agent plate 3 directly is placed in the groove that heating function is arranged on the disk 5, by the hot piece 4 that is positioned at its below it is heated.The lower surface of heater element 1 and fin 2 are fitted, and can carry out the energy transmission with air faster by fin 2.Heat-conducting block 6 is fixed on disk 5 lower surfaces, by press strip 7 heater element 1, fin 2 and heat-conducting block 6 is fixed together.Like this, each parts of whole heater just are in a relatively-stationary position.When disk 5 rotates around its center, just can drive the heater element 1, heat-conducting block 6, hot piece 4 and the fin 2 that are fixed thereon and together rotate.No matter disk 5 rotates to any position, and what biochemical reaction reagent can both be constant is in the heated condition.
Heater specific operation process of the present invention is as follows:
At first agent plate 3 is placed into disk 5(heating function is arranged) groove in, subsequently in agent plate 3 filling reaction liquid, heater element 1 is heated.In heating, disk 5 rotates, and allows next groove on the disk 5 be in the position of the groove that is heating, and another agent plate is placed in this dead slot, this agent plate is carried out work such as imbibition, liquid feeding.Like this, rotate by disk 5, hot piece 4, heat-conducting block 6, heater element 1, fin 2 that drive is fixed on it together rotate, when not influencing original heating work, can also operate other agent plate, increase work efficiency to a great extent, thereby realize high efficiency, high-throughout automatically working process.
More than show and described basic principle of the present invention, principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present invention; the present invention also has various changes and modifications without departing from the spirit and scope of the present invention, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
