In order to facilitate understanding of the technical solution of the present invention, before the detailed description, the basic testing principle of the existing thromboelastography instrument is first explained.

Since the thromboelastography is used for monitoring and analyzing the coagulation state of a blood sample, the final result of the coagulation process is the formation of a blood clot, and the physical properties of the blood clot, such as the strength and stability of the blood clot, determine whether the blood clot has normal coagulation function.

As shown in fig. 1, monitoring the physical properties of a blood clot is based on the following principles: a specially prepared cylindrical cup, still containing blood, was rotated at an angle of 4 degrees and 45 minutes for 10 seconds per rotation. The movement of the blood sample is monitored by a needle suspended from the wire and immersed in the blood sample. After the fibrin-platelet complex adheres the cup and the needle together, rotational force generated by the rotation of the cup can be transmitted to the needle in the blood sample. The strength of the fibrin-platelet complex can affect the amplitude of the needle movement so that a strong blood clot can synchronize the needle movement with the cup movement. Thus, the amplitude of the needle movement is directly related to the strength of the blood clot that has formed. When the clot is retracted or dissolved, the needle is decoupled from the clot and the motion of the cup is no longer transmitted to the needle.

The rotational movement of the needle is converted by an electromechanical transducer into an electronic signal which can be monitored by a computer to form a thromboelastogram (see figure 2).

As described above, the conventional thromboelastography device has a complicated structure, and therefore, the device has a large volume and is complicated to operate, and thus, it is difficult to perform bedside diagnosis.

Therefore, it is necessary to provide a thrombus elasticity test device which is small in size, simple to operate and capable of performing bedside diagnosis.

The testing unit 20 includes a testing body 21, a testing part 22 and an analyzing module, the testing body 21 is detachably disposed at the testing position 111, the testing body 21 has a testing channel 211 for accommodating a blood sample 200 to be tested, the testing part 22 is mounted on the handheld housing 10, the testing part 22 includes an air pressure source 221 and a pressure detector 222, and the analyzing module is in communication connection with the testing part.

It should be understood that under the pressure provided by the air pressure source 221, the blood sample to be tested will flow in the test channel 211 under pressure, and as the clot inside the blood sample to be tested 200 gradually forms, the yield stress of the clot inside the blood sample to be tested 200 also increases, the flow rate of the blood sample to be tested 200 also decreases, and the pressure value detected by the pressure detector 222 also becomes larger accordingly, so that the pressure value recorded in the whole test process reflects the whole process of the pressure change of the clot inside the blood sample to be tested 200 from the generation strength to the maximum strength.

The display 30 is mounted on the hand-held housing 10, the display 30 is in communication connection with the testing unit 20, and the display 30 is used for displaying the result of the thromboelastometry test. In some embodiments, the handheld thromboelastometry device 100 further comprises a keyboard 40, the keyboard 40 is mounted to the housing 10, and the keyboard 40 is operable to control the operation of the test unit 20.

Thus, the air pressure source 221 is used for providing air pressure to the test channel 211, and the thrombus elasticity test result of the blood sample 200 to be tested is obtained through the pressure detected by the pressure detector 222, so that the structure of the thrombus elasticity test device is simplified, the volume of the thrombus elasticity test device is reduced, the sampling and testing can be realized, and the operation error caused by multiple sample processing because the conventional thrombus elasticity tester needs to take blood and resist coagulation firstly, needs to be activated by adding an activating agent before testing, and is accelerated by adding a coagulant and the like is avoided. Locate hand-held type shell 10's test position through setting up test body 21 detachably that has test channel 211, be about to including the test portion 22 of air pressure source 221 and pressure detector 222 and the separable setting of test body 21 that has test channel 211, so can the exclusive use test body 21 gather the blood specimen 200 that awaits measuring, the operation is simpler, in addition, still can show the thrombus elasticity test result through display 30, consequently, the utility model discloses a hand-held type thrombus elasticity testing arrangement 100, small and easy operation can realize the diagnosis of bedside.

Present thrombus elastogram appearance often also need follow the patient and extract a large amount of blood on one's body and detect, and the utility model discloses a hand-held type thrombus elasticity testing arrangement 100 can reduce blood volume because of the mode that adopts pressure detection by a wide margin to test time is short, and efficiency of software testing also can improve. In addition, current thrombelastogram appearance clinical use condition is harsher, and is very sensitive to the vibration of putting levelness and environment, and the utility model discloses a hand-held type thrombelastogram testing arrangement 100, it is not high to the environmental requirement, is favorable to realizing the diagnosis of bedside.

As shown in fig. 6, in some embodiments, the testing body 21 may be a long strip, so that it can be easily held to improve the convenience of collecting the blood sample 200. Specifically, the extending direction of the test passage 211 is parallel to the lengthwise direction of the test body 21. Thus, the structure of the test body 21 can be made compact, the volume of the test body 21 can be reduced, and the hand-held thrombus elasticity test apparatus 100 can be further miniaturized.

Referring again to fig. 5 and 6, in some embodiments, the testing body 21 further has a first opening 212, and the first opening 212 is communicated with the testing channel 211. Specifically, the air pressure source 221 may provide air pressure to the test channel 211 through the first opening 212. In some embodiments, the testing body 21 is further provided with a second opening 213, and the second opening 213 is communicated with the testing channel 211. Specifically, the test channel 211 communicates with the outside atmosphere through the second opening 213. In this manner, a pressure differential is maintained within test channel 211 such that a blood sample to be tested will flow under pressure within test channel 211, thereby causing pressure detector 222 to detect the progress of the pressure change.

In some embodiments, the testing body 21 further has a blood storage cavity 214, the blood storage cavity 214 is used for storing the blood sample 200 to be tested, and the blood storage cavity 214 is communicated with the testing channel 211 and is located at the upstream end of the testing channel 211 along the pressure flow direction of the blood sample 200 to be tested. The blood storage cavity 214 is configured to collect the blood sample to be tested before testing, so as to prevent the blood sample 200 to be tested from flowing in the testing channel 211 before testing, thereby causing testing errors. Specifically, the blood storage chamber 214 is located between the first opening 212 and the test channel 211. Thus, the blood sample 200 to be tested can enter the blood storage cavity 214 through the first opening 212, and the blood sample 200 to be tested in the blood storage cavity 214 can enter the testing channel 211 during the testing process. In some embodiments, the depth direction of the blood storage cavity 214 intersects the extension direction of the test channel 211, preferably, the depth direction of the blood storage cavity 214 is perpendicular to the extension direction of the test channel 211, and in particular, the depth direction of the blood storage cavity 214 is parallel to the width direction of the test body 21. Thus, the internal structure of the test body 21 can be further made compact, and the volume of the test body 21 can be reduced.

In some embodiments, the testing body 21 further has a waste blood chamber 215, the waste blood chamber 215 is used for storing the tested blood sample 200, and the waste blood chamber 215 is communicated with the testing channel 211 and is located at the downstream end of the testing channel 211 along the pressure flow direction of the tested blood sample 200. Thus, the blood sample 200 to be tested in the testing channel 211 flows under pressure until it reaches the waste blood chamber 215 to complete the test, and the waste blood chamber 215 is configured to prevent the tested blood sample 200 from flowing outside the testing body 21 to pollute the external environment. Specifically, the waste blood chamber 215 communicates with the second opening 213 and the test channel 211, respectively. The pressure differential of the test channel 211 may be maintained by the waste blood chamber 215.

Thus, the internal structure of the test body 21 can be further made compact, and the volume of the test body 21 can be reduced.

In some embodiments, in order to prevent the blood sample 200 to be tested in the waste blood chamber 215 from overflowing from the second opening 213 under the pressure influence of the testing channel 211, the waste blood chamber 215 may include a first waste blood chamber and a second waste blood chamber connected to each other, the first waste blood chamber is located between the testing channel 211 and the second opening 213, and the second waste blood chamber is located at a side of the testing channel 211 away from the second opening 213, so that the volume of the waste blood chamber 215 can be increased by the second waste blood chamber, and the blood sample 200 to be tested can be prevented from flowing to the second opening 213 directly after the waste blood chamber 215 is pressurized, but the second waste blood chamber can share part of the pressure, and the outflow path of the blood sample 200 to be tested to the second opening 213 can be prolonged.

It should be understood that the testing body 21 of the present invention is a disposable device, and the testing portion 22 can be used many times without replacement, so that the cost is saved.

In some embodiments, the test channel 211 comprises a capillary channel. It is noted that the capillary passage means a passage having a very small inner diameter, for example, a passage having an inner diameter of 1 mm or less. The blood volume of the blood sample to be tested can be further reduced by arranging the capillary channel, and in addition, the relationship between the pressure detected by the pressure detector 222 and the thrombus elastic force test result of the blood sample to be tested is also analyzed by utilizing the theory of measuring the blood viscosity by using a capillary method.

In some embodiments, the handheld apparatus 100 further includes a limiting member disposed on the handheld housing 10, and the limiting member is capable of cooperating with the testing body 21 to limit the testing body 21 at the testing position 111. The position of the test body 21 at the test position 111 is prevented from shifting by the position limiter, so as to affect the testing of the test portion 22 on the blood sample 200 to be tested in the test body 21.

Specifically, the locating part includes the joint portion that can with test body 21 joint, and joint portion locates and holds in the chamber 11.

Thus, the sealing cover 223 can seal the periphery of the first opening 212, ensure reliable alignment and combination of the testing part 22 and the testing body 21, and avoid the leakage of the pressure provided by the air pressure source 221 due to unstable alignment and combination of the testing part 22 and the testing body 21, thereby affecting the detection reliability. Referring to fig. 5 and 7, in other embodiments, the sealing cover 223 may only have a third communication channel communicating with the first opening 212, and the air pressure source 221 and the pressure detector 222 are both communicated with the third communication channel. Specifically, the test section 22 further includes an air pressure pipe 224 and a pressure detection pipe 225, both ends of the air pressure pipe 224 are connected to the air pressure source 221 and the third communication pipe, respectively, and both ends of the pressure detection pipe 225 are connected to the pressure detector 222 and the third communication pipe, respectively. Thus, the structure of the sealing cover 223 can be further simplified.

In a specific embodiment, the sealing cover 223 has a square shape, and the first opening 212 has a circular shape, and in other embodiments, the sealing cover 223 may have other shapes, such as a plunger type, and the like, without limitation.

Referring to fig. 3 and 4 again, in some embodiments, the hand-held housing 10 includes a housing 12 and a cover 13, the accommodating cavity 11 is disposed in the housing 12, the housing 12 is opened with an opening 121 communicating with the accommodating cavity 11, the testing body 21 can be disposed on the testing position 111 through the opening 121, the cover 13 is disposed at the opening 121, and the testing portion 22 is disposed on the cover 13. So, can make things convenient for the dismouting of test body 21 through setting up uncovered 121 to through locating lid 13 with test portion 22, can locate test position 111 at test body 21 after, locate uncovered 121 with lid 13 lid after, can realize test portion 22 and test body 21's counterpoint and combine, improved detection efficiency. Specifically, the keyboard 40 is disposed on a side of the cover 13 facing away from the opening 121.

Further, the cover 13 has a rotating shaft, and the rotating shaft is located at one side of the opening 121 and is parallel to the opening 121. So, can improve the maneuverability and the convenience of lid 13, in addition, for the setting mode of other directions, the pivot that is on a parallel with uncovered 121 setting can avoid lid 13 to produce the friction between rotation in-process and test body 21, leads to test body 21 to rock and causes the blood sample 200 that awaits measuring in test body 21 to rock and break away from test body 21, or leads to test body 21 skew to cause test portion 22 and test body 21 to counterpoint inaccurately.

To facilitate an understanding of the present application, the testing principles of the handheld thromboelastometry device 100 of the present application are described in detail below.
