Detailed description of the invention
For making the purpose of this utility model embodiment, technical scheme and advantage clearer, below in conjunction with
Accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out clear,
It is fully described by, it is clear that described embodiment is a part of embodiment of this utility model rather than complete
The embodiment in portion, based on the embodiment in this utility model, those of ordinary skill in the art are not making
The every other embodiment obtained on the premise of creative work, broadly falls into the model of this utility model protection
Enclose.
As it is shown in figure 1, this utility model embodiment provides a kind of heater, this heater is permissible
Including herein below:
For holding the container 1 of liquid;
Contact with described container 1, for the liquid held in described container 1 is heated at least one
Individual heater 2;
Be connected with at least one heater 2 described, for gather each heater 2 Current Temperatures,
And the Current Temperatures and the design temperature prestored according to each heater 2 is to each heating described

Parallel operation 6 is by being connected with at least one critesistor 4, being connected with comparator 5, to realize comparator 5
With being connected of temperature sensor 4, for the current resistive value that each critesistor 4 exports is converted to
The current temperature value of respective heater 2, and the current temperature value of each heater 2 is exported to comparing
Device 5.
In like manner, comparator 5, target heater being controlled continuation heating or heating can be stopped
After, can be with the startup of time delay a period of time, such as, this delay duration can be 1 minute, when time delay
After length reaches, continue to gather Current Temperatures target heater changed by signal adapter 6.At this
In one embodiment of utility model, refer to Fig. 4, this heater may further include: input is single
Unit 7, is connected with comparator 5, for inputting design temperature and/or delay duration to comparator 5.
Wherein, this design temperature can come really according to the Liquids held in container 1 and testing goal
Fixed.As a example by the liquid held in container 1 is as blood, this blood is for realizing the analysis of thrombelastogram
Monitoring, therefore, this design temperature can be 37 degree.
Wherein, heater 2 number being arranged on container 1 is the most, enters the liquid held in container 1
The speed of row heating is the fastest, and heats also can be the best, and when the number of heater 2 is too many, it is also possible to
The corresponding cost increasing heater, it is therefore preferred that the number of this heater can be three.
In one embodiment of this utility model, this at least one heater 2 can be arranged on container 1
Bottom, it is also possible to be arranged on the side of container 1.
Preferably, in order to ensure that the liquid to holding in container 1 uniformly heats, this at least one add
Hot device 2 is arranged at the bottom even of container 1.
In one embodiment of this utility model, in order to realize further uniformly the adding of liquid in container 1
Heat, this at least one heater includes: ceramic heater.
As a example by the number of heater is three, the distribution to this heater illustrates, and refer to Fig. 5,
These three heaters are evenly distributed on the bottom of container 1.
In one embodiment of this utility model, the shape of this container 1 can include circle, polygon,
Any one in irregular figure.
This utility model embodiment additionally provides a kind of coagulation analysis system, and this coagulation analysis system can be wrapped
Include the arbitrary described heater of above-described embodiment and thrombelastogram instrument;Wherein,
Described thrombelastogram instrument, for carrying out the blood held in the described container of described heater
Coagulation analysis.
In one embodiment of this utility model, this coagulation analysis system may further include: drives dress
Put and saddle;Wherein,
Described driving means, is used for driving described saddle to rotate;
The described container of described heater is fixed on described saddle.
For making heater provided by the utility model and coagulation analysis system clearer, below to add
Blood is heated by thermal, and utilizes thrombelastogram instrument to enter the blood of heating in this heater
As a example by row coagulation analysis, being described in detail this workflow, refer to Fig. 6, this workflow can
To comprise the following steps:
Step 601: blood to be detected is poured in the container of heater.
Step 602: be fixed on saddle by the container of heater, saddle is according to the driving of driving means
Rotate.
Wherein, step 601-step 602, for heating and then carry out the preparation of coagulation analysis to blood
Work.
Step 603: utilize input block input design temperature 37 degree in the comparator of heater and prolong
Shi Shichang 1 minute, comparator stores this design temperature and delay duration.
Step 604: utilize at least one heater being arranged on container that the blood in container is added
Heat.
Step 605: the critesistor being connected with each heater gathers the Current Temperatures of respective heater,
According to Current Temperatures output current resistive value to signal adapter.
Step 606: each current resistive value, according to the characteristic of critesistor, is changed by signal adapter
For the Current Temperatures of respective heater, Current Temperatures is exported to comparator.
The characteristic of its correspondence of critesistor of different model is different, accordingly, it would be desirable to know this temperature-sensitive electricity in advance
The corresponding relation of the characteristic of resistance, i.e. resistance value and temperature value, in order to signal adapter can be more accurately
Resistance value is converted to the temperature of respective heater, thus it is right to ensure that comparator can judge more accurately
The control of heater, and then improve the accuracy of coagulation analysis.
Step 607: comparator compares the Current Temperatures of each heater and the design temperature of storage,
When determining the Current Temperatures of target heater less than design temperature, perform step 608;Determining that target adds

Step 608: control this target heater and proceed heating, and stop gathering signal adapter pair
The current temperature value that the resistance value of corresponding critesistor output is changed, performs step 609.
Step 609: after comparator waits 1 minute, starts, and performs step 607.
Step 610: control target heater and stop heating, and stop gathering signal adapter to corresponding heat
The current temperature value that the resistance value of quick resistance output is changed, performs step 609.
Above-mentioned steps 603-step 610, for the mistake utilizing heater to heat the blood in container
Journey.In this process, when to the temperature of heater after design temperature keeps a time period, permissible
Being defined as having reached design temperature by the temperature of now blood, now, thrombelastogram instrument can be to blood
Carry out coagulation analysis, produce thrombelastogram.Wherein, this time period can be arranged based on experience value.
Such as, it is two minutes.
Wherein, thrombelastogram be reflection blood coagulation dynamically change (include fibrinous formation speed,
Dissolved state and the robustness of solidifying shape, elastic force degree) index.
