Description

Technical Field

[0001] This utility model relates to the technical field of medical devices, and in particular to a blood testing machine. Background Technology

[0002] In the medical field, blood testing is a commonly used method. Medical staff analyze the components in a patient's blood to aid in diagnosis. To facilitate blood testing, the blood sample is first processed by centrifugation. The different concentrations of blood cells, serum, and plasma cause them to separate under centrifugal force, allowing for separate analysis and improving testing efficiency. In the prior art, a utility model patent with patent application number 202320220006.4 discloses a centrifuge for blood testing, which mainly consists of a turntable and centrifuge tubes. The centrifuge tubes are mounted on the turntable, and a centrifugation tank is set inside the centrifuge tubes. In use, the staff puts the test tube containing the blood sample into the centrifugation tank, and then the rotation of the turntable causes the centrifuge tube to rotate. The inventors believe that there are the following problems in the use of this centrifuge: before centrifuging the blood, in order to prevent the blood from clotting, medical staff will add an anticoagulant to the blood sample. Then, the medical staff will turn the test tube over to make the anticoagulant fully dispersed in the blood sample before centrifugation. However, relying on medical staff to manually turn the test tubes over is extremely labor-intensive and inconvenient for large-scale blood testing. Therefore, there is a need for a centrifuge for blood testing with an automatic shaking function. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a blood testing machine that can automatically invert the test tube containing the blood sample during centrifugation, so that the anticoagulant can be fully dispersed into the blood, reducing the labor intensity of medical staff, and is convenient and highly practical.

[0004] This utility model discloses a blood testing machine, comprising a support leg, a housing, and a lid. The housing is fixedly mounted on the upper end of the support leg. A chamber is provided inside the housing, and an opening communicating with the chamber is provided at the upper end of the housing. The lid is installed at the opening at the upper end of the housing. It also includes a centrifugation mechanism and a tilting mechanism, both installed within the housing's chamber. The centrifugation mechanism performs centrifugation, and the tilting mechanism performs tilting. When testing blood, the blood sample is first placed into a test tube, then an anticoagulant is added to the test tube, and finally a sealing plug is placed at the top of the test tube. The test tube is placed into the inverting mechanism, which inverts the tube to promote the movement of the anticoagulant and blood, ensuring the anticoagulant is fully dispersed in the blood. Afterward, the test tube is removed from the inverting mechanism and placed into the centrifugation mechanism for centrifugation. The centrifuged blood sample is then placed into an external blood testing facility for analysis. The system automatically inverts the test tube during centrifugation, ensuring the anticoagulant is fully dispersed in the blood, reducing the workload of medical staff, and is convenient and highly practical.

[0005] Preferably, the flipping mechanism includes a drive mechanism, a support plate, a rotating shaft, and a bearing. The support plate has multiple circular grooves, each containing a test tube clamp. The rotating shaft is fixedly installed on the left side of the support plate and rotatably mounted on the bearing, which is fixedly installed inside the chamber of the housing. The drive mechanism is installed inside the housing and is used to drive the support plate to rotate. When flipping blood samples, multiple test tubes containing blood samples are placed in the multiple circular grooves of the support plate, and then clamped and fixed by multiple test tube clamps. The drive mechanism is then activated to rotate the support plate, which in turn rotates the multiple test tubes, thereby ensuring thorough mixing of the blood sample and anticoagulant within the test tubes. This improves the mixing efficiency between the blood sample and the anticoagulant.

[0006] Preferably, the driving mechanism includes a DC motor, a rotating shaft, and a support frame. The DC motor is fixedly installed inside the cavity of the housing, and the rotating shaft is fixedly installed at the right end of the support plate. The rotating shaft is coaxial with the pivot shaft, and the input end of the rotating shaft is connected to the output end of the DC motor. The rotating shaft is rotatably mounted on the support frame, and the support frame is fixedly installed inside the cavity of the housing. When driving the support plate to rotate, the DC motor is turned on, and the DC motor rotates the support plate through the rotating shaft, which facilitates the rotation of the support plate.

[0007] Preferably, the centrifugation mechanism includes a disc and a power mechanism. The disc has multiple slots around its circumference, each containing a test tube clamp. The disc is mounted on the power mechanism, which drives the disc to rotate. After the test tube containing the blood sample is flipped on the support plate, the test tube is removed from the support plate and then placed into the slot of the disc. The test tube is then fixed in place, and the power mechanism rotates the disc, causing the test tube to rotate and the blood sample inside the test tube to separate into layers under centrifugal force. This facilitates the testing of blood samples.

[0008] Preferably, the power mechanism includes a drive motor, a fixed plate, and a rotating shaft. The drive motor is fixedly installed at the lower end of the chamber, the fixed plate is fixedly installed inside the chamber, and the rotating shaft is rotatably installed on the fixed plate. The lower end of the rotating shaft is connected to the output end of the drive motor, and the disc is fixedly installed at the upper end of the rotating shaft. When the disc rotates, the drive motor is turned on, and the drive motor rotates the disc through the rotating shaft. This facilitates the centrifugation of blood samples.

[0009] Preferably, the upper part of the rotating shaft is provided with multiple threaded holes, the disc is provided with multiple through holes that communicate with each other, and the disc is provided with multiple bolts. The multiple bolts pass through the multiple through holes on the disc and are screwed into the multiple threaded holes on the rotating shaft. Through the above arrangement, the disc and the rotating shaft are detachably connected, which facilitates the replacement of the disc.

[0010] Preferably, it also includes multiple lights, all of which are installed inside the chamber of the enclosure; this arrangement makes the chamber of the enclosure brighter, facilitating the monitoring of the operation process.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: when centrifuging blood samples, the test tube containing the blood sample can be automatically flipped, so that the anticoagulant can be fully dispersed into the blood, reducing the labor intensity of medical staff, and is convenient to use and highly practical.

[0018] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein.

A chamber is provided inside the housing 2, and an opening communicating with the chamber is provided at the upper end of the housing 2. The lid 3 is installed at the opening at the upper end of the housing 2. Both the centrifugation mechanism and the tilting mechanism are installed in the chamber of the housing 2. The centrifugation mechanism has a centrifugation function, and the tilting mechanism has a tilting function. When testing blood, the blood sample is first placed into a test tube, then an anticoagulant is added to the test tube, and finally a sealing plug is placed on the upper end of the test tube. The test tube is then placed into the inverting mechanism, which inverts the tube to promote the movement of the anticoagulant and blood, ensuring the anticoagulant is fully dispersed in the blood. Afterward, the test tube is removed from the inverting mechanism and placed into the centrifugation mechanism for centrifugation. The centrifuged blood sample is then placed into an external blood testing facility for analysis. The system automatically inverts the test tube during centrifugation, ensuring the anticoagulant is fully dispersed in the blood, reducing the workload of medical staff. It is convenient to use and highly practical.

[0020] like Figure 1 and Figure 3 The flipping mechanism includes a drive mechanism, a support plate 4, a rotating shaft 5, and a bearing 6. The support plate 4 has multiple circular grooves, each containing a test tube clamp. The rotating shaft 5 is fixedly installed on the left side of the support plate 4 and rotatably mounted on the bearing 6, which is fixedly installed inside the chamber of the housing 2. The drive mechanism is installed inside the housing 2 and is used to drive the support plate 4 to rotate. When flipping blood samples, multiple test tubes containing blood samples are placed in the multiple circular grooves of the support plate 4, and then clamped and fixed using multiple test tube clamps. The drive mechanism is then activated, causing the support plate 4 to rotate. The support plate 4 drives the multiple test tubes to rotate, thus ensuring thorough mixing of the blood sample and anticoagulant within the test tubes. This improves the mixing efficiency between the blood sample and the anticoagulant.

[0021] like Figure 3 The drive mechanism includes a DC motor 7, a rotating shaft 8, and a support frame 9. The DC motor 7 is fixedly installed in the cavity of the housing 2, and the rotating shaft 8 is fixedly installed at the right end of the support plate 4.

The rotating shaft 8 is rotatably mounted on the support frame 9, and the support frame 9 is fixedly installed in the cavity of the housing 2. When driving the support plate 4 to rotate, the DC motor 7 is turned on, and the DC motor 7 rotates the support plate 4 through the rotating shaft 8, which facilitates the rotation of the support plate 4.

[0022] like Figure 1 and Figure 4 The centrifugation mechanism includes a disc 10 and a power mechanism. The disc 10 has multiple slots around its circumference, each containing a test tube clamp. The disc 10 is mounted on the power mechanism, which drives the disc 10 to rotate. After the test tube containing the blood sample is flipped on the support plate 4, the test tube is removed from the support plate 4 and placed into the slot of the disc 10. The test tube is then fixed in place, and the power mechanism rotates the disc 10, causing the test tube to rotate and the blood sample inside the test tube to separate into layers under centrifugal force. This facilitates the testing of blood samples.

The drive motor 11 is fixedly installed at the lower end of the chamber 2 of the housing 2, the fixed plate 12 is fixedly installed inside the chamber 2, and the rotating shaft 13 is rotatably installed on the fixed plate 12. The lower end of the rotating shaft 13 is connected to the output end of the drive motor 11, and the disc 10 is fixedly installed on the upper end of the rotating shaft 13. When the disc 10 is rotated, the drive motor 11 is turned on, and the drive motor 11 rotates the disc 10 through the rotating shaft 13. This facilitates the centrifugation of blood samples.

[0024] Continue to refer to Figure 4 The upper part of the rotating shaft 13 is provided with multiple threaded holes, the disc 10 is provided with multiple through holes that are connected vertically, and the disc 10 is provided with multiple bolts 14.
