Background technology
It is the conventional project of clinical examination that hemorheology detects, and its operating process is such: and whole blood test → whole blood is centrifugal → and blood plasma tests.Because existing hemorheology checkout equipment and centrifugation apparatus are two kinds of equipment fully independently, there is not structural contact each other, be transferred to special blood plasma testing apparatus after the centrifugal treating again, there is transfer in sample, thereby there is following drawback in existing operating process: 1, need manually sample to be come and gone twice transfer between centrifugation apparatus and checkout equipment, increase operator's labour intensity, prolonged detection time, reduced work efficiency; 2, increased contamination probability owing to shifting to transport, patients'blood sample especially, various viruses are hidden in wherein, often become pollution source; 3, because the sample that detects is more, very approximate each other, increased the error probability that sample is fastened one person's story upon another person in the transport process.
The utility model content
At the prior art above shortcomings, the purpose of this utility model provides centrifugal automatically, the locating device of a kind of hemorheology instrument sample, and the centrifugal and location of sample can be finished by an automatic gas on this device in batches, and sample need not to shift.
The purpose of this utility model be achieved in that a kind of hemorheology instrument sample centrifugal automatically/locating device, it is characterized in that: it is made up of centrifugal mechanism, detent mechanism two parts.Centrifugal mechanism comprises centrifugal motor and the sample disc that is driven by it, and sample disc is provided with the test tube rack of fixed sample; Detent mechanism comprises the steady arm whether positioning drive unit, the jacking gear that makes the positioning drive unit lifting and the test sample dish of the rotation of driving sample disc put in place, and the driving power of sample disc can switch between centrifugal motor and positioning drive unit under the jacking gear effect.
Further, the output shaft of lifting motor is connected with hoistable platform by screw rod in the described jacking gear, and positioning drive unit is installed on the hoistable platform.The output shaft of positioning motor is connected with driving-disc in the positioning drive unit, and driving-disc is provided with and drives the driver part that sample disc is rotated.
Described steady arm is made of the location transmitters of being located at the location receivers on the positioning drive unit and be located on each test tube rack.Location transmitters is the magnetic mark group of being located on the test tube rack, and location receivers is the magnetic induction sensor of being located on the positioning drive unit.
The utility model unites two into one centrifugal required sample disc and the location required sample disc of sampling by the clutch of controlling and driving dish and sample disc, has realized the automatic switchover that sample is centrifugal and sample is located.When sample was centrifugal, driving-disc separated with sample disc, and sample disc becomes centrifugal sample disc by centrifugal Electric Machine Control; When sample was taken a sample, driving-disc and sample disc engaged, and sample disc is controlled by positioning motor by driving-disc, becomes the location sample disc, thereby sample is centrifugal, positioning function is incorporated on the same device and carries out automatically.Centrifugal and the location a shared sample disc, sample need not the transfer.Compared to existing technology, the utlity model has following beneficial effect:
1, avoided the round transfer of sample between centrifugation apparatus and checkout equipment;
2, avoided the pollution that may occur, sample can not pollute surrounding environment on the one hand, and sample also exempts from the pollution of environment on the other hand;
3, the gross error of fastening one person's story upon another person of having avoided the batch sample in coming and going transfer process, may occur;
4, reduce operator's labour intensity, shortened detection time, improved work efficiency;
5, two equipment combine, and its price is lower than the price of two equipment, can reduce the purchase cost of equipment.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Referring to Fig. 1, as can be seen, the utility model comprises the two large divisions: centrifugal mechanism and detent mechanism from the figure.The purpose of centrifugal mechanism is by the rotating speed of setting sample to be carried out centrifugal treating in the time of setting; The purpose of detent mechanism is the fixedly sample position that target sample accurately is sent to sampling probe, and Fig. 1 left-hand component is sampling mechanism, because it is a prior art, the utility model is not explained.Respectively centrifugal mechanism and detent mechanism are elaborated below.
Referring to Fig. 1 and Fig. 2, centrifugal mechanism comprises centrifugal motor 2 and the sample disc 1 that is driven by it, and sample disc 1 is provided with the test tube rack 4 of fixed sample.
Referring to Fig. 1 and Fig. 3, detent mechanism comprises steady arm, positioning drive unit and jacking gear thereof.The output shaft of positioning motor 6 is connected with driving-disc 7 in the positioning drive unit, is provided with in the bottom of driving-disc 7 to drive the driver part 12 that sample disc is rotated.This driver part 12 can be the driving cushion rubber that frictionally rotates sample disc, also can be other structure, such as tooth combination or similar structures.
Jacking gear can have two kinds of forms, the lifting motor 8 shown in a kind of figure of being goes up, and the output shaft of lifting motor 8 is connected with hoistable platform 11 by screw rod 9, and the top of positioning drive unit is installed in the bottom of hoistable platform 11.Owing to when screw rod 9 stationkeeping, the hoistable platform 11 that is connected with its screw thread are rotated at screw rod 9, drive positioning drive unit and realize lifting.Another kind of is lifting liquid (vapour) cylinder, and positioning drive unit is located on the piston of lifting liquid (vapour) cylinder.Because this can just can realize its accompanying drawing of Therefore, omited without performing creative labour those of ordinary skill in the art's tool.In order to make the steady lifting of hoistable platform 11 and positioning drive unit, the utility model is provided with riser guide 10.
