Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an automatic shaking device for preventing coagulation in blood collection tubes. Background Technology

[0002] In clinical practice, some patients require a large number of blood samples to be drawn for testing at once. Medical staff need to shake the blood and anticoagulant in each blood collection tube thoroughly. However, when shaking manually, the wrists of medical staff are prone to soreness, which leads to uneven mixing of blood and anticoagulant as the blood collection tubes are shaken. Furthermore, the amplitude of shaking varies from person to person and there is an upper limit to the amplitude, which can easily cause poor mixing of blood and anticoagulant.

[0003] Chinese utility model patent (CN 214915490U) discloses a blood collection tube shaker. It uses a blood collection tube limiting mechanism to limit the blood collection tube placed in the tube hole, preventing it from being thrown out during shaking. A motor drives a rotating shaft to rotate the frame, shaking the blood collection tube effectively and facilitating even mixing of the collected blood with the pre-reserved anticoagulant. The motor is a braked stepper motor, which drives the shaking frame to reciprocate at the shaking position, simulating manual shaking to mix the blood and anticoagulant. While this method improves the shaking effect compared to other vibration-based methods, from a clinical perspective, there is still significant room for improvement in the shaking effect of the blood collection tube. Therefore, a blood collection tube shaking device with a better shaking effect is needed. Utility Model Content

[0004] This utility model is an automatic shaking device for preventing coagulation in blood collection tubes, providing a shaking device for blood collection tubes with better shaking effect.

[0005] To achieve the above objectives, the technical solution of this utility model is: an automatic shaking device for preventing coagulation in blood collection tubes, including a housing, wherein a driving device is fixedly installed inside the housing;

[0006] The drive device includes a driving gear and a driven gear that mesh with each other.

A switch for controlling the motor to turn on and off is provided on the surface of the housing.

[0007] The shaking box includes a detachably connected box body and a box cover, wherein the inner surfaces of the box body and the box cover respectively form a first receiving groove and a second receiving groove that conform to the shape of the top and bottom of the blood collection tube.

[0008] As a further improvement, both the driving gear and the driven gear are helical gears.

[0009] As a further improvement, the pitch circle diameter of the driving gear is smaller than that of the driven gear.

[0010] As a further improvement, the shaking box has a rectangular structure, and the end of the transmission rod away from the driven gear is fixedly connected to the intersection of the diagonals of one side wall surface of the shaking box.

[0011] As a further improvement, a plurality of elastic limiting pieces are fixedly provided on the inner surface edge of the first receiving groove.

[0012] As a further improvement, the opening edge of the second receiving slot is located at one-third of the height of the blood collection tube.

[0013] As a further improvement, a sponge layer is provided on the inner surface of the second receiving groove.

[0014] As a further improvement, a support frame is detachably installed inside the box. The support frame includes legs and a limiting plate fixed to the top of the legs. The outer peripheral surface of the limiting plate is in contact with the inner surface of the box, and a fixing opening is provided on the surface. The fixing opening corresponds one-to-one with the second receiving groove. The diameter of the fixing opening is smaller than the diameter of the top of the blood collection tube.

[0015] As a further improvement, the outer surfaces of the opposite edges of the box body and the box cover are connected by snap fasteners.

[0016] As a further improvement, the shaking box is provided in two parts, with the driven gear and the transmission rod fixedly connected. After the transmission rod passes through the shaft of the driven gear, its two ends extend out of the housing and are fixedly connected to the middle position of the outer surface of one side of the two shaking boxes.

[0026] The following embodiments further illustrate the content of this utility model, but should not be construed as limiting the utility model. Any modifications or substitutions made to the methods, steps, or conditions of this utility model without departing from its spirit and essence are within the scope of this utility model.

[0027] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings and examples.

[0028] Please see Figures 1 to 7 As shown, this utility model discloses an automatic anti-coagulation shaking device for blood collection tubes, comprising a housing 1, with a drive device 2 fixedly installed inside the housing 1; the drive device 2 includes a driving gear 3 and a driven gear 4 meshing with each other, the other end of the driving gear 3 being connected to the output shaft of a motor 5, and the other end of the driven gear 4 being fixedly connected to a transmission rod 6, the transmission rod 6 extending out of the housing 1 and fixedly connected to the middle position of one side of the outer surface of the shaking box 7, and a switch 8 for controlling the opening and closing of the motor 5 being provided on the surface of the housing 1; the shaking box 7 includes a detachably connected box body 9 and a box cover 10, the inner surfaces of the box body 9 and the box cover 10 respectively forming a first receiving groove 12 and a second receiving groove 13 that fit the top and bottom shapes of the blood collection tube 11.

[0029] The drive device 2 is fixed inside the housing 1 by a bracket or support. When using the automatic shaking device for preventing coagulation of blood collection tubes in this application, firstly, the box body 9 and the box cover 10 of the shaking box 7 are opened to expose the first receiving groove 12 and the second receiving groove 13 of the box body 9, which are adapted to the bottom shape of the blood collection tube 11. After the medical staff finishes collecting blood, the blood collection tube 11 is vertically inserted into the first receiving groove 12 and the second receiving groove 13 of the box body 9. The positions of the first receiving groove 12 and the second receiving groove 13 are one-to-one, and the number is at least 10. After placement, the box cover 10 is fastened to connect the box body 9 and the box cover 10.

[0030] It should be noted that the outer edges of the box body 9 and the box cover 10 are in contact with each other, and the surfaces are connected by buckles 20, connecting straps, etc. The first receiving groove 12 and the second receiving groove 13 on the box body 9 and the box cover 10 fix the top and bottom of the blood collection tube 11, thereby fixing the blood collection tube 11 in the shaking box 7. In order to mix the blood and anticoagulant in the blood collection tube 11 more evenly, the automatic shaking device of this application rotates the blood collection tube 11, which was originally in a vertical static preparatory state, 360° a certain number of times. Since the patient's information label 21 is affixed to the surface of the blood collection tube 11 in advance, the information label 21 refers to the patient information, the type of blood collection tube 11, and the barcode, etc., affixed to the blood collection tube 11. To avoid wear and tear on the patient's information label 21 during the shaking process, which could result in missing information, the positions of the first receiving groove 12 and the second receiving groove 13, which are correspondingly set on the box body 9 and the box cover 10, are designed to avoid the position of the information label 21. Preferably, in order to further ensure that the blood collection tube 11 remains vertical when inserted, the first receiving groove 12 on the box cover 10 is aligned with the top of the blood collection tube 11 when the box cover 10 is closed. The depth of the second receiving groove 13 is one-third of the height of the blood collection tube 11. This ensures that the information label 21 is avoided while better fixing the vertical position of the blood collection tube 11 after insertion, ensuring the initial state of all blood collection tubes 11, and further making the blood and anticoagulant in the blood collection tube 11 mix more evenly.

[0031] After the housing 9 and the cover 10 are fastened and fixed in place, the drive device 2 is not activated, the blood collection tube 11 is stationary and upright. When the medical staff turns on the switch 8 of the drive device 2, it should be noted that the housing 1 can be equipped with a controller to control or adjust the speed of the motor 5. The controller is electrically connected to the motor 5. Since one end of the drive gear 3 is connected to the output shaft of the motor 5 and the other end meshes with the driven gear 4, and the other end of the driven gear 4 is fixedly connected to the transmission rod 6, the transmission rod 6 extends out of the housing 1 and is fixedly connected to the middle position of one side of the outer surface of the shaking box 7. Since the drive gear 3 rotates, it drives the driven gear 4 to rotate, which in turn drives the shaking box 7 through the transmission rod 6. Preferably, the transmission rod 6 extends out of the housing 1 and is fixedly connected to the middle position of the bottom outer surface of the box 9, or the transmission rod 6 extends out of the housing 1 and is fixedly connected to the outer surface of the middle position of one side wall of the box 9. This allows the shaking box 7 to rotate from the connection position with the transmission rod 6. The blood collection tube 11 placed inside the shaking box 7 rotates clockwise or counterclockwise at the same time. The rotation speed of the motor 5 is controlled so that the rotation speed of the blood collection tube 11 inside can be set according to actual needs. It can be no less than 2 seconds per revolution. One revolution refers to one cycle in which the blood collection tube 11 returns to the vertical position after rotation. It can be shaken by rotating 2.5-4 revolutions.

[0032] Because manual shaking requires shaking each blood collection tube 11, when there are many blood collection tubes 11, the wrist pain of medical staff will also lead to uneven mixing of blood and anticoagulant as they shake the later blood collection tubes 11. In addition, the shaking amplitude varies from person to person and there is an upper limit to the amplitude of the shaking, which results in poor mixing of blood and anticoagulant.

[0033] Therefore, the automatic anticoagulant mixing device for blood collection tubes in this application uses a clockwise or counterclockwise rotation of the blood collection tube 11 to make the blood and anticoagulant inside mix more evenly, freeing up the hands of medical staff.

[0034] Please refer to the following: Figures 2 to 7 As shown, specifically, the meshing driving gear 3 and driven gear 4 are both helical gears. The output shaft of the motor 5 is perpendicular to the transmission rod 6. An opening is provided on the surface of the housing 1 for the transmission rod 6 to extend out. The transmission rod 6 is fixedly connected to the axis of the driven gear 4. This design is not only simple and portable, but also makes it easier for medical staff to carry to the patient's bedside. After blood collection, the blood collection tube 11 can be placed directly on the shaking box 7. After blood collection from multiple blood collection tubes 11 is completed, the motor 5 switch 8 is turned on immediately to shake the tubes, avoiding the blood from clotting inside the blood collection tubes due to the long transport time.

[0035] Please refer to the following: Figures 2 to 7 As shown, specifically, the pitch circle diameter of the driving gear 3 is smaller than that of the driven gear 4, which further facilitates the control of the rotation speed of the shaking box 7 and prevents it from rotating too fast.

[0036] Please refer to the following: Figure 1 and Figure 2 As shown, specifically, the shaking box 7 has a rectangular structure. The end of the transmission rod 6 away from the driven gear 4 is fixedly connected to the intersection of the diagonals on one side wall of the shaking box 7. That is, when the box body 9 and the box cover 10 are closed to form the whole shaking box 7, the end of the transmission rod 6 away from the driven gear 4 is fixedly connected to the intersection of the diagonals on one side wall of the shaking box 7. In this way, after the shaking box 7 is rotated, the blood and anticoagulant in each blood collection tube 11 are mixed more evenly.

[0037] Please refer to the following: Figure 3As shown, specifically, multiple elastic limiting pieces 14 are fixedly provided on the inner surface edge of the first receiving groove 12. It should be noted that the top of the blood collection tube 11 is the end with the cap fastened. Therefore, the top of the blood collection tube 11 has a larger cross-sectional diameter than its bottom. When the box cover 10 is fastened, the top of the blood collection tube 11 is inserted into the opening of the first receiving groove 12, passing through the opening formed by the multiple elastic limiting pieces 14, thereby locking the top of the blood collection tube 11. In this way, after the shaking operation of the blood collection tube 11 is completed, the blood collection tube 11 can be taken out directly when the box cover 10 is opened, making the operation more convenient.

[0038] Please refer to the following: Figures 2 to 7 As shown, specifically, the opening edge of the second receiving groove 13 is located at one-third of the height of the blood collection tube 11. When the blood collection tube 11 is inserted into the second receiving groove 13, the opening edge of the second receiving groove 13 is located at one-third of the height of the blood collection tube 11. This ensures that the information tag 21 is avoided while better fixing the vertical state of the blood collection tube 11 after it is inserted, and further improves the mixing effect of blood and anticoagulant in the blood collection tube 11.

[0039] Please refer to the following: Figure 4 As shown, specifically, the inner surface of the second receiving groove 13 is provided with a sponge layer 15, which better adapts to the tube wall shape near the bottom of the blood collection tube 11, and better keeps the blood collection tube 11 in a vertical state after it is placed in.

[0040] Please refer to the following: Figure 5 as well as Figure 6 As shown, specifically, a support frame 16 is detachably installed inside the housing 9. The support frame 16 includes legs 17 and a limiting plate 18 fixed to the top of the legs 17. The outer peripheral surface of the limiting plate 18 contacts the inner surface of the housing 9, and a fixing opening 19 is provided on the surface. The fixing opening 19 corresponds one-to-one with the second receiving groove 13. The diameter of the fixing opening 19 is smaller than the top diameter of the blood collection tube 11. In use, the support frame 16 is placed inside the housing 9. At this time, the limiting plate 18 is parallel to the bottom surface of the housing 9, and the legs 17 rest on the bottom surface of the housing 9 where the second receiving groove 13 is provided. The blood collection tube 11 is inserted from the fixing port 19 and then fixed in the second receiving groove 13. The fixing port 19 further fixes the position of the blood collection tube 11. Since the diameter of the fixing port 19 is smaller than the diameter of the top of the blood collection tube 11, the cap of the top of the blood collection tube 11 is stuck in the fixing port 19. This not only makes it easy for the first receiving groove 12 to be aligned with the cap of the blood collection tube 11 after the box cover 10 is closed, but also allows the support frame 16 to be directly removed from the box body 9 after the blood collection tube 11 has been shaken, making it more convenient to use.

[0041] Please refer to the following: Figures 1 to 7As shown, specifically, the outer surfaces of the opposite sides of the box body 9 and the box cover 10 are connected by a buckle 20, which realizes the fastening of the box body 9 and the box cover 10, and prevents the box body 9 and the box cover 10 from opening when the shaking box 7 is rotated.

[0042] Please refer to the following: Figure 7 As shown, specifically, there are two shaking boxes 7. The driven gear 4 is fixedly connected to the transmission rod 6. The transmission rod 6 passes through the shaft of the driven gear 4 and its two ends extend out of the housing 1 and are fixedly connected to the middle position of the outer surface of one side of the two shaking boxes 7. This allows more blood collection tubes 11 to be shaken at the same time.

[0043] The above-described embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made by those skilled in the art to the technical solutions of the present utility model without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
