Description

Technical Field

[0001] The present application relates to the field of test cups, and in particular to an ear-hanging test cup for thromboelastography testing. Background Art

[0002] At present, in clinical diagnosis, research on guidance of antithrombotic treatment for coronary heart disease, screening for resistance to antiplatelet drugs, and analysis of the causes of acute or subacute thrombosis during interventional procedures is usually evaluated with the help of thromboelastography. The thromboelastogram is an indicator used to reflect the dynamic changes in blood coagulation, specifically including the formation rate, dissolution state, and firmness and elasticity of fibrin. In actual testing, blood is actually placed in a test cup. As time goes on, the coagulation of the blood gradually increases, and the elasticity of the blood also gradually increases. The sensor is used to detect the compressive elasticity of the blood, and then the thromboelastogram is obtained.

[0003] The test cup used in the testing process serves as a carrier for holding blood, which affects the accuracy and stability of the test results. Although the test cups currently used can be used for blood testing, their accuracy needs to be further improved. Therefore, the inventors believe that providing a test cup that improves detection accuracy is a problem that needs to be solved at present. Summary of the Invention

[0004] In order to improve the test accuracy of the test cup, the present application provides an ear-hanging test cup for thromboelastography testing.

[0005] The present application provides a thromboelastography test cup with an ear hook, which adopts the following technical solution:

[0006] A hanging ear test cup for thromboelastography testing comprises a main body cup and an hanging ear cup suspended on the main body cup. The hanging portion between the hanging ear cup and the main body cup is in line contact. The hanging ear cup can swing around the main body cup. The main body cup is provided with a baffle located in the hanging ear cup.

[0007] By employing the above technical solution, during actual testing, blood and a sensor are placed in a test cup. The ear cup is swung, causing the blood in the test cup to be compressed by the ear cup and baffle. The sensor then measures the compressive elastic force generated by the blood, and further measures the change in this compressive elastic force over time, thereby generating a thromboelastogram. This technical solution utilizes the swinging of the ear cup to cause the baffle and ear cup to compress the blood, thereby accurately generating a thromboelastogram and effectively ensuring the test cup's detection accuracy.

[0008] Optionally, the main body cup is provided with a funnel extending into the ear cup, and a liquid leakage port is opened at the bottom of the funnel.

[0009] By adopting the above technical solution, on the one hand, it is convenient for the staff to add the sample to be tested into the test cup. On the other hand, the funnel-shaped design is conducive to the rapid flow of the sample into the test cup, reducing the possibility of the sample gradually becoming a colloid and increasing viscosity due to excessive flow time.

[0010] Optionally, the baffle is connected to the funnel, and the baffle is located at the center line of the leakage port.

[0011] By adopting the above technical solution, the sample to be tested can flow evenly to both sides of the baffle, thereby realizing bidirectional testing in the test cup. That is, after the test cup is swung in one direction to measure data, the test cup is then swung in the other direction to measure new data of the sample, thereby greatly shortening the cycle interval between the two tests and further improving the accuracy of the data.

[0012] Optionally, a liquid separator is provided at the end of the baffle located in the funnel.

[0013] By adopting the above technical solution, the surface tension of the liquid at the leakage port is destroyed by using the liquid separator, which helps the sample to pass through the leakage port smoothly.

[0014] Optionally, the main body cup is provided with a channel, the funnel is provided in the channel, two hanging ears are symmetrically provided on the hanging ear cup, and the main body cup is provided with hanging platforms on both sides of the channel for hanging the hanging ears, and the cross-section of the hanging platform is V-shaped.

[0015] By adopting the above technical solution, the contact between the ear cup and the main cup is made into line contact, so that the ear cup can swing freely with the hanging platform as the axis without resistance, thereby more accurately measuring the compression elastic force of the sample.

[0016] Optionally, a notch communicating with the channel is formed on the side wall of the main body cup, and the notch is aligned with the center position of the channel in the lateral direction of the main body cup.

[0017] By adopting the above technical solution, the sensor can pass through the gap, which facilitates the movement of the sensor and reduces the possibility that the accuracy of the detection data will be affected due to the obstruction of the movement of the sensor.

[0018] Optionally, the gaps between the inner wall of the ear cup and the outer wall of the funnel are the same.

[0019] By adopting the above technical solution, when the ear cup is swinging, the shear resistance of the sample in the ear cup to the ear cup along the swinging direction is equal, thereby ensuring the accuracy of the data detected by the sensor.

[0020] Optionally, there are a plurality of main body cups, which are connected into a plurality of rows, and the ear cups in two adjacent rows are staggered.

[0021] By adopting the above technical solution, the staggered ear cups can detect multiple samples at the same time and will not affect each other during movement, thereby ensuring the accuracy of the test data.

[0022] Optionally, the main body cup is injection molded from plastic material.

[0023] By adopting the above technical solution, it is easy to form, low in cost, and the strength can meet the requirements.

[0024] Optionally, the ear cup is injection molded from plastic material.

[0025] By adopting the above technical solution, it is easy to form, low in cost, and the strength can meet the requirements.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. This application utilizes the line contact between the ear cup and the main cup to allow the ear cup to swing approximately without resistance around the contact line. During the swinging process of the ear cup, the baffle and the ear cup squeeze the sample, allowing the sensor to accurately detect the compressive elastic force of the sample, thereby obtaining an accurate thromboelastogram and ensuring the accuracy of the test cup's detection data.

[0028] 2. After the ear cup of this application is installed in the main cup, the gap between the inner wall of the ear cup and the outer wall of the funnel is equal. This ensures that when the ear cup swings, the shear resistance of the sample on the ear cup along the swing direction is equal, thereby further ensuring the accuracy of the data detected by the sensor and improving the accuracy of the test cup detection data.

[0029] 3. This application sets the baffle at the center line of the funnel leakage port, so that the baffle can destroy the surface tension of the sample at the leakage port, which helps the sample to pass through the leakage port smoothly. At the same time, it can also make the sample flow evenly to both sides of the baffle, which is helpful for subsequent two-way detection of the sample. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The following is combined with Figure 1-6 This application is described in further detail.

[0038] The embodiment of the present application discloses an ear-hanging test cup for thromboelastography testing.

[0039] Example 1

[0040] Reference Figure 1 A thromboelastography test cup with an ear loop includes a main cup 1 and an ear loop 2. The main cup 1 includes a rectangular top plate 11 and four side plates 12 for supporting the top plate 11. The ear loop 2 is located between the four side plates 12 and is suspended from the top plate 11. The top plate 11 has a channel 13. When testing a blood sample, the sample is added to the ear loop 2 through the channel 13, and then the ear loop 2 is swung to test the sample.

[0041] Reference Figure 2 and Figure 3 The top plate 11 has clearance openings 111 on both sides of the channel 13. The top plate 11 is connected to a hanging platform 14 located in the clearance openings 111. Two hanging ears 21 are symmetrically provided on the cup mouth of the hanging ear cup 2. Both the main body cup 1 and the hanging ear cup 2 are injection-molded with transparent plastic, which makes the main body cup 1 and the hanging ear cup 2 have a certain strength, reduces the deformation of the hanging ear cup 2 due to the compression elastic force of the sample during the swinging process, thereby ensuring the accuracy of the test data, and at the same time, also makes the hanging ear 21 have a certain elasticity. When installing the hanging ear cup 2, insert the hanging ear cup 2 from the bottom of the main body cup 1, squeeze the two hanging ears 21 so that the hanging ear 21 can be inserted into the clearance opening 111, and then release the hanging ear 21 so that the hanging ear 21 is suspended on the hanging platform 14, thereby completing the installation of the hanging ear cup 2.

[0042] In order to allow the ear cup 2 to swing freely on the main cup 1, the top cross-section of the hanging platform 14 is V-shaped. When the ear 21 is hung on the hanging platform 14, the contact between the ear 21 and the hanging platform 14 is line contact, so that the ear cup 2 can swing freely within a certain angle with almost no resistance, which is beneficial to the subsequent detection of samples.

[0043] Reference Figure 4 and Figure 5 The top plate 11 is provided with a funnel 3 located in the channel 13. When the ear cup 2 is installed on the main cup 1, the funnel 3 is inserted into the ear cup 2. A leakage port 31 is provided at the bottom of the funnel 3, which makes it convenient for the staff to add the sample to the ear cup 2. The funnel 3 is provided with a baffle 4 located at the leakage port 31. The baffle 4 is provided with a liquid separator 41 located in the leakage port 31, and the baffle 4 is located at the center line of the leakage port 31 in the width direction of the top plate 11. After the sample is added to the funnel 3, the sample falls into the ear cup 2 through the leakage port 31. As the sample flows in the funnel 3, the sample will slowly turn into a colloid and increase in viscosity over time. When the sample flows to the leakage port 31, the liquid separator 41 destroys the surface tension of the sample, which helps the sample pass through the leakage port 31 smoothly. In addition, the liquid separation knife 41 also makes the sample flow evenly to both sides of the baffle 4, so that when the ear cup 2 swings, the sample can be tested bidirectionally on both sides of the baffle 4, which greatly shortens the cycle interval between two tests and improves the accuracy of the test data.

[0044] When the ear cup 2 is mounted on the main cup 1, the gaps between the ends of the baffle 4 along the length of the top plate 11 and the inner sidewall of the ear cup 2, as well as the gaps between the bottom surface of the baffle 4 and the inner sidewall of the ear cup 2, should be minimized based on sample characteristics, such as viscosity and fluidity, while ensuring free swinging of the ear cup 2. For example, when testing whole blood samples, the gaps between the ends of the baffle 4 and the inner sidewall of the ear cup 2, as well as the gaps between the bottom surface of the baffle 4 and the inner sidewall of the ear cup 2, should be no greater than 0.35 mm. This minimizes the possibility that swinging of the ear cup 2 could cause sample movement, thereby ensuring the accuracy of the detected data.

[0045] Funnel 3 is a tapered hexagonal shape, corresponding to the ear cup 2. Once installed, the gap between the inner wall of the ear cup 2 and the outer wall of the funnel 3 is equal. During testing, the sensor is placed in the ear cup 2. As the ear cup 2 swings, the equal gap between the ear cup 2 and the funnel 3 ensures that the sample inside the ear cup 2 exerts equal shear resistance on the ear cup 2 along the swinging direction, thus helping to ensure the accuracy of the sensor data.

[0046] The two side panels 12 along the length of the main cup 1 are each provided with a corresponding notch 121. These notches 121 align with the centerline of the channel 13 along the width of the main cup 1. During testing, the sensor is placed within the ear cup 2, with the sensor's connectors passing through the notches 121. The notches 121 facilitate the sensor's movement as it swings along with the ear cup 2, minimizing the impact of sensor movement on detected data.

[0047] The implementation principle of Example 1 is as follows: the sample is added to the funnel 3. Under the action of the baffle 4, the sample flows evenly to both sides of the baffle 4. The sensor on one side of the baffle 4 pushes the ear cup 2. Under the pressure of the ear cup 2 and the baffle 4, the sample where the sensor is located is compressed. When the ear cup 2 swings to the maximum position, it maintains balance. The sensor measures the compression elastic force. The sensor then retracts and the ear cup 2 returns to its initial position. The sensor on the other side of the baffle 4 then pushes the ear cup 2 in the opposite direction. When the ear cup 2 swings to the maximum position, it maintains balance. The sensor measures the compression elastic force. The sensor then retracts and the ear cup 2 returns to its initial position. The above steps are repeated until the test process is completed, and the thromboelastogram is finally obtained. The ear cup in this embodiment can accurately detect the compression elastic force of the sample by virtue of the cooperation between the main cup 1 and the ear cup 2, effectively ensuring the accuracy of the ear cup detection.

[0048] Example 2

[0049] Reference Figure 6 This embodiment differs from Example 1 in that multiple main body cups 1 are provided, interconnected and arranged in two rows, allowing staff to simultaneously test multiple samples and improving testing efficiency. In addition to this embodiment, in other implementations, multiple main body cups 1 may also be arranged in multiple rows. The main body cups 1 in two adjacent rows are staggered to minimize the impact of swinging ear cups 2 on test data due to collision.

[0050] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
