Description

Technical Field

[0001] The utility model relates to the field of medical instruments, in particular to an automated rotatable blood collection tube stand. Background Art

[0002] Blood collection tube racks are often used in daily blood collection work in hospitals. After the specimen is collected, the test tube needs to be manually inverted 360° and mixed 5-8 times to fully mix the blood and anticoagulant to prevent the formation of tiny clots that affect the test results. After the specimen is collected, it is placed on the blood collection tube rack and then transported to the laboratory for testing.

[0003] However, in daily work, the traditional blood collection tube rack is fixed and cannot be rotated and turned upside down. The nurse needs to manually shake the blood and anticoagulant to fully mix them. A patient may need to draw multiple blood samples at one time. The nurse needs to shake the blood tube while collecting the samples, which is easy to distract attention and slow down the collection speed, resulting in a long time for collecting blood samples. On the one hand, it is easy to cause patients to feel nervous. On the other hand, the distraction of the nurse may cause the blood sample to shake unevenly, resulting in unqualified blood samples. A second puncture is required to collect blood samples, which brings pain to the patient. Therefore, it is necessary to invent an automated rotatable blood collection tube rack to solve the above problems. Utility Model Content

Clamping assemblies 3 are provided on both sides of the middle of the upper surface of the base 1, and a connecting plate 4 is provided in the middle of the upper surface of the base 1. The clamping assembly 3 comprises a clamping plate 15 provided on the upper surface of the base 1, and a slider 16 is fixed to the bottom end of the clamping plate 15. Slide grooves 17 are provided at both ends of the upper surface of the base 1, and the slider 16 is located inside the slide groove 17, and one end of the slider 16 is connected to the slide groove 17 through a spring 18. The inner wall of one end of the connecting plate 4 is connected, and the clamping plate 15 can automatically clamp and limit the connecting plate 4 under the action of the spring 18. An electrical connection groove 11 is opened in the middle of the upper surface of the base 1, and a plurality of positioning grooves 12 distributed in a ring array are opened on the surrounding side of the electrical connection groove 11. An electrical connection head 13 is fixed in the middle of the lower surface of the connecting plate 4. The electrical connection head 13 is inserted into the interior of the electrical connection groove 11 to play a role of electrical connection. A plurality of positioning columns 14 distributed in a ring array are fixed to the edge of the lower surface of the connecting plate 4. The positioning columns 14 are adapted to the positioning grooves 12 to play a role of positioning, thereby preventing the connecting plate 4 from being separated from the base 1.

[0021] Specifically, a support rod 5 is connected to the middle part of the upper surface of the connecting plate 4, and a motor box 6 is connected to the top end of the support rod 5. A clamping assembly 7 is arranged on the outer side of the upper end of the support rod 5, and the clamping assembly 7 corresponds to the lower end of the motor box 6. The clamping assembly 7 includes a screw sleeve 19 which is sleeved on the outer side of the upper end of the support rod 5, and the screw sleeve 19 is movably connected to the support rod 5 through internal and external threads. A damping plate 20 is fixed to the top end of the screw sleeve 19, and a damping ring 21 is inlaid in the middle part of the lower surface of the motor box 6. The damping plate 20 is adapted to the damping ring 21. By twisting the screw sleeve 19, the screw sleeve 19 drives the damping plate 20 to move upward until the damping plate 20 contacts the damping ring 21, which plays a role of damping limit, limits the motor box 6, and prevents the motor box 6 from rotating at will.

[0022] More specifically, a motor 8 is embedded in the middle of one end of the motor box 6, and a test tube rack 9 is fixed to the output shaft of the motor 8. The motor 8 is a forward and reverse motor, which can drive the test tube rack 9 to rotate forward and reverse. The test tube rack 9 is provided with a plurality of through grooves distributed in a rectangular array, and a silicone sleeve 10 is embedded in the through groove. A plurality of strip-shaped protrusions in a ring array are arranged on the inner side of the silicone sleeve 10, which can squeeze and limit the blood specimen test tube to prevent the test tube from falling. Both sides of one end of the motor box 6 are fixed with protrusions 22, and one end of the protrusion 22 is provided with a slot 23, and the slot 2 3 is internally inserted with a limiting head 24, one end of the limiting head 24 is connected to the bottom of the slot 23 through a compression spring, a limiting groove 25 adapted to the other end of the limiting head 24 is provided in the middle of one side of the test tube rack 9, the other end of the limiting head 24 is set to a hemispherical structure, and the limiting groove 25 is set to a hemispherical groove, and the limiting head 24 cooperates with the limiting groove 25 to provide a certain stability to the test tube rack 9, so that the test tube rack 9 can maintain a certain stability when it is placed horizontally or inverted horizontally, and at the same time does not affect the test tube rack 9 to rotate with the motor 8.

[0023] Working principle of this utility model:

[0024] After maintenance of the device, first move the two clamps 15 outward to compress the spring 18, then insert the electrical connector 13 on the connecting plate 4 into the electrical connection slot 11 on the base 1, and then insert the positioning column 14 on the connecting plate 4 into the positioning slot 12 on the base 1, then loosen the clamp 15, and the clamp 15 is reset under the action of the spring 18. At this time, the two clamps 15 cooperate to clamp the connecting plate 4 to limit the position, so that the connecting plate 4 is installed stably. When the device is working, first rotate the test tube rack 9 to a suitable direction, and then screw the screw sleeve 19. The sleeve 19 drives the damping plate 20 to move upward until the damping plate 20 contacts the damping ring 21, which plays a role of damping limit, limits the motor box 6, and then limits the test tube rack 9. Then, the blood sample test tube is inserted into the through groove on the test tube rack 9. The silicone sleeve 10 in the through groove squeezes the test tube to a limit. Then, the motor 8 is started by the switch. The motor 8 drives the test tube rack 9 to rotate, so that the test tube rack 9 rotates forward for ten minutes at the set frequency, and then reverses for ten minutes, and circulates for one to two hours, so that the blood sample in the test tube can be fully mixed and will not coagulate.

[0025] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein.
