[0014] Advantages of the present invention: The present invention provides a test device and system for cross-matching blood. The collection seat arranged on the top of the circulation seat is used to realize the collection place of blood collection, and the blood is introduced into the cross cavity for cross-test. The limiting seat fixedly installed on the collection seat is used to load the limiting mechanism.

[0019] The following gives specific embodiments.

[0020] Please refer to Figures 1-9 , the present invention provides a test device and system for cross-matching blood, including a base 1, on which a main body 2 of the test device is fixedly installed, a bearing seat 3 is fixedly installed inside the main body 2 of the test device, a flow-through seat 4 is fixedly arranged on the bearing seat 3, a cross cavity 5 is opened inside the flow-through seat 4, a fixed seat 6 is fixedly arranged on the bearing seat 3, and a loading mechanism is arranged on the fixed seat 6; A collection seat 9 is arranged on the top of the flow-through seat 4, a limiting seat 15 is fixedly installed on the collection seat 9, a limiting mechanism is arranged on the limiting seat 15, a sealing cover 10 is arranged on the top of the collection seat 9, a connecting mechanism is arranged on the sealing cover 10, and the connecting mechanism cooperates with the limiting mechanism; A rubber sleeve 17 communicating with it is fixedly installed on the top of the sealing cover 10, a collection mechanism is fixedly installed on the top of the rubber sleeve 17, a bottom collection pipe 22 is fixedly arranged inside the rubber sleeve 17, a reserved cavity 21 is arranged between the bottom collection pipe 22 and the rubber sleeve 17, and a round hole 23 is opened on the bottom collection pipe 22, and the round hole 23 communicates with the reserved cavity 21; A sinking groove 26 is opened inside the collection seat 9, and a flow hole 27 is penetrated and opened on the collection seat 9 and inside the sinking groove 26, and the flow hole 27 communicates with the cross cavity 5; During operation, the test device main body 2 is loaded through the base 1, and the cross-matching test is completed in cooperation with the test device main body 2 fixedly installed on the base 1. The carrier seat 3 fixedly installed inside the test device main body 2 is used to load the circulation seat 4. During the cross-matching test, the blood fusion and crossover are realized through the circulation seat 4 fixedly arranged on the carrier seat 3. The crossover cavity 5 opened inside the circulation seat 4 is used as the liquid fusion space for the experiment. The fixing seat 6 fixedly arranged on the carrier seat 3 is used to load and fix the loading mechanism. The loading mechanism arranged on the fixing seat 6 is used to limit the collection seat 9, so as to facilitate the subsequent test; The collection seat 9 arranged on the top of the circulation seat 4 is used to realize the collection place of blood collection and introduce the blood into the crossover cavity 5 for crossover test. The limit seat 15 fixedly installed on the collection seat 9 is used to load the limiting mechanism. Under the cooperation of the limiting mechanism and the connecting mechanism, the convenient fitting and separation of the collection seat 9 and the sealing cover 10 are realized. When blood needs to be collected, the collection seat 9 and the sealing cover 10 are in a fitting state. When the inside of the collection seat 9 needs to be cleaned, the collection seat 9 and the sealing cover 10 are in a separated state. The limiting mechanism arranged on the limit seat 15 cooperates with the connecting mechanism to load and limit the sealing cover 10. The sealing cover 10 arranged on the top of the collection seat 9 is used for blood collection in the cross-blood test.

The collection mechanism fixedly installed on the top of the rubber sleeve 17 is used to realize blood collection during the cross-blood test. The bottom collection tube 22 fixedly arranged inside the rubber sleeve 17 serves as the cavity in contact with the blood. With the cooperation of the rubber sleeve 17, the blood enters the inside of the bottom collection tube 22 under negative pressure. Specifically, during blood collection, by pressing the rubber sleeve 17, the air in the reserved cavity 21 is compressed. And because the reserved cavity 21 is connected and communicated with the inside of the bottom collection tube 22, the inside of the bottom collection tube 22 is also in a negative pressure state. When the rubber sleeve 17 is released, the rubber sleeve 17 rebounds, and the reserved cavity 21 returns to its original volume, so that the inside of the bottom collection tube 22 is pressurized, so that the blood automatically enters the bottom collection tube 22 and waits for the subsequent test process; The sunken groove 26 opened on the inner side of the collection base 9 is used to divert the blood inside the bottom collection tube 22. After the bottom collection tube 22 finishes collecting the blood, due to the downward factor of gravity, the blood enters the sunken groove 26 and automatically flows into the flow hole 27 that penetrates through and is located on the inner side of the sunken groove 26 on the collection base 9. Then, as the blood flows, it enters the inner side of the cross cavity 5 to achieve a closed blood cross-test, thus ensuring the accuracy of the blood cross-test data.

[0022] Furthermore, as Figure 6 shown, the limiting mechanism includes a limiting frame 16 fixedly installed inside the limiting seat 15, and the limiting frame 16 is in an L shape; During operation, the limiting frame 16 fixedly installed inside the limiting seat 15 is used to limit the collection base 9, so as to facilitate the convenient separation and fitting of the collection base 9 and the sealing cover 10. And the limiting frame 16 is in an L shape, which can ensure good fitting of the sealing cover 10 relative to the collection base 9.

[0023] Furthermore, as Figure 6 shown, the connecting mechanism includes a connecting seat 11 arranged on the sealing cover 10. An extension plate 12 is fixedly installed at the bottom of the connecting seat 11, and a limiting rod 13 is fixedly installed at the bottom of the extension plate 12.

[0024] Furthermore, as Figure 6 shown, a limiting spring 14 is fixedly arranged on the limiting rod 13, and one end of the limiting spring 14 away from the limiting rod 13 is connected to the top inside the limiting seat 15; During operation, the limiting spring 14 fixedly arranged on the limiting rod 13 is used to limit the limiting rod 13. The stress generated when the limiting spring 14 deforms can not only ensure sufficient sealing performance after the collection seat 9 and the sealing cover 10 are fitted, but also improve the convenience of separating the limiting rod 13 from the limiting frame 16. After the limiting rod 13 is separated from the limiting frame 16, the limiting spring 14 drives the limiting rod 13 to contract until it is close to the top of the limiting seat 15, facilitating the next use.

[0025] Further, as Figure 8 shown, the collection mechanism includes a top collection tube 18 fixedly installed at the top of a rubber sleeve 17.

During operation, the top collection tube 18 fixedly installed at the top of the rubber sleeve 17 is used for loading the insertion tube 19, the insertion tube 19 inserted at one end of the top collection tube 18 away from the rubber sleeve 17 is used for loading the contact tube 20, and the contact tube 20 fixedly installed at the top of the insertion tube 19 is in direct contact with the blood to be tested, thereby realizing the safe and convenient collection of blood.

[0026] Further, as Figure 8 shown, the contact tube 20 is made of glass material; During operation, since the contact tube 20 is made of glass material, it is convenient to clean the contact tube 20.

[0027] Further, as Figure 4 and Figure 9 shown, a sealing ring groove 25 is formed at the top of the collection seat 9, and a sealing ring 24 is fixedly arranged at the bottom of the sealing cover 10. The sealing ring 24 is in interference fit with the sealing ring groove 25; During operation, the sealing ring groove 25 formed at the top of the collection seat 9 is used to cooperate with the sealing ring 24 to realize the sealing performance after the collection seat 9 and the sealing cover 10 are fitted, ensuring the normal collection of blood.
