Problems solved by technology

Therefore, the rotation angle and rotation speed of the cup or pin are fixed regardless of the measurement in the high-viscoelastic region where blood coagulation progresses, or in the low-viscoelastic region, so that desired resolution cannot be obtained. , there are situations where it is difficult to evaluate the efficacy of the drug
Furthermore, these devices are expensive, so lower price and smaller / lighter devices are required

Embodiment approach

[0069] The control part 1 receives an instruction from the control device, and drives the reciprocating rotation operation of the stirring part 3 via the elastic body 2.

[0070] The elastic body support portion 1B performs a predetermined reciprocating rotational motion by the drive of the servo motor 1A. In addition, elastomers

[0071] In addition, the configuration of the control unit 1 is not limited to the example of FIG. 1 . As long as the control unit 1 can support the elastic body 2 and

[0073] In addition, the elastic body 2 is not limited to the example of FIG. 1 . As long as the elastic body 2 transmits the prescribed reciprocating rotational motion to the

[0077] The bearing 3B supports the reciprocating rotation of the stirring pin 3C. In Fig. 1, the bearing 3B is a magnetic bearing formed of a ring magnet,

[0079] The pin hole 3D serves as a mark indicating the reference position of the rotation transmission portion 3A. By using the sensor 5 to detect and ana...

Embodiment 1

[0120] In Example 1, changes in the coagulation state of blood were measured. For the blood in the container 4, after using

Embodiment 2

[0123] In Example 2, the change in the coagulation state of an agarose solution having a concentration of 1.5% was measured. When the measurement starts

[0124] After about 20 minutes elapsed from the start of the measurement, the temperature of the agarose solution reached about 25°C, and gelation started. in measuring

Abstract

The present invention provides a blood coagulation testing device and a blood coagulation testing method. The blood coagulation testing device comprises: a container, which is filled with the blood of the test object; a stirring part, which stirs the blood of the test target in the container; The received force deforms correspondingly; the control part makes the elastic body reciprocate with the shaft of the stirring part as the rotating shaft, and controls the reciprocating rotation at a position separated from the rotating shaft by a predetermined diameter, thereby transmitting a predetermined rotational motion to the stirring part, The stirring part is reciprocated in the circumferential direction; the measuring part measures the rotation angle involved in the reciprocating rotation of the stirring part.

Description

Blood coagulation test device and blood coagulation test method technical field [0001] The present invention relates to a blood coagulation test apparatus and a blood coagulation test method. Background technique [0002] For the treatment of hemophilia with a decrease / deficiency of blood coagulation factors that function to coagulate blood during bleeding, etc. [0002] Evaluation of pathological conditions, or evaluation of the efficacy of preparations such as hemostatic drugs, and blood tests during blood coagulation The state of liquid solidification. As a method of examining the state of blood coagulation, for example, there is known The blood of the image (hereinafter also referred to as a blood sample) is irradiated with light and the amount of scattered light is measured to detect the coagulation and calculate the coagulation time. Optical inspection method (for example, refer to Patent Document 1). In addition, it is known to make a pin immersed in a cup conta...
