Abstract
The utility model relates to an air bath thermostat, which belongs to medical instruments. A temperature sensor is plugged in the sensor-mounting hole of a constant-temperature heating plate, an overheat protector is plugged in the square mounting hole of the constant-temperature heating plate, an annular heater band is pressed on the bottom of the constant-temperature heating plate by a heater band holddown, the constant-temperature heating plate is provided with plate-fixing holes, a top heating plate cover is fixedly connected with the constant-temperature heating plate through set screws, and an airtight air cavity is defined by the top heating plate cover and the constant-temperature heating plate. The air bath thermostat has the advantages that: the structure is novel, a reaction vessel can always be uniformly heated within the reaction time, other medium which can affect turbidity measurement does not exist between the reaction vessel and a measuring light path, and the precision of measurement cannot be affected.
Description
Technical field
The utility model belongs to Medical Instruments, refers in particular to a kind of thermostat.
Background technology
When thermostat is measured mainly for immunoturbidimetry, for the temperature control equipment of reaction liquid within the reaction time.The thermostatic control system of Medical Devices mainly adopts water-bath type and roasting mode to add heat control at present.Water-bath type is that the reaction vessel that will measure is inserted and carried out constant temperature in the Water Tank with Temp.-controlled and process.Roasting mode adopts metal medium to form a radiating surface more, reaction vessel is placed radiating surface before, carry out temperature control.Water-bath type, because reaction vessel places tank, the optical path when reactant is measured must pass through tank, affects the turbidimetry of system.The mode of baking, temperature is heated inhomogeneous.
Summary of the invention
The utility model provides a kind of air bath thermostat, and to solve water-bath type, the reactant optical path affects turbidimetry through tank; Baking type, the temperature inhomogeneous problem of being heated.
The technical solution of the utility model is: peg graft in the installation of sensors hole of temperature sensor and heated at constant temperature disk body; the installation square hole of overheat protector and heated at constant temperature disk body is pegged graft; the annular-heating band overlays by heating tape pressing plate and heated at constant temperature disk body bottom; the disk body fixed orifice is arranged on the heated at constant temperature disk body; the heating plate loam cake is fixedly connected with the heated at constant temperature disk body by gib screw, forms airtight air chamber with disk body.
The utility model advantage is: novel structure, reaction vessel are in the thermally equivalent state always within the reaction time, do not have the medium of other influences turbidimetry between reaction vessel and the optical path, do not affect measuring accuracy.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the A-A cut-open view of Fig. 1.
Embodiment
Temperature sensor 1 is pegged graft with the installation of sensors hole of heated at constant temperature disk body 7; overheat protector 2 is pegged graft with the installation square hole of heated at constant temperature disk body 7; annular-heating band 3 overlays by heating tape pressing plate 5 and heated at constant temperature disk body 7 bottoms; disk body fixed orifice 4 is arranged on the heated at constant temperature disk body 7; heating plate loam cake 6 is fixedly connected with heated at constant temperature disk body 7 by gib screw, forms airtight air chamber with disk body.
Temperature control unit is according to the temperature value of heated at constant temperature dish needs heating, and heating power corresponding to heating tape output to being fixed on dish ground carries out thermostatic control and regulate.Temperature by the residing environment temperature of temperature measurement unit surveying instrument and heated at constant temperature dish; temperature value according to environment temperature and heated at constant temperature dish; calculate the heating power of constant temperature heating plate; by temperature control unit the heated at constant temperature dish is added heat control, by the temperature protection unit whole device is carried out temperature protection simultaneously.
