Description

Technical Field

[0001] The present invention relates to the technical field of medical appliances, and specifically refers to an automatic blood shaking device for vascular surgery. Background Art

[0002] In vascular surgery, arterial blood sampling (such as blood gas analysis) needs to be immediately shaken to prevent interference with gas exchange caused by uneven contact between blood and anticoagulant. In addition, patients in vascular surgery often need to frequently monitor coagulation function (such as postoperative anticoagulant therapy). If the sodium citrate tube is not fully mixed, the coagulation status may be misjudged, increasing the risk of bleeding or thrombosis. Therefore, it may be necessary to shake the blood. Traditionally, manual shaking is used, which has a high working intensity, low efficiency, and poor shaking effect. For this reason, a dedicated automatic blood shaking device has emerged.

[0003] For example, Chinese Patent Application No. CN201720974168.1 discloses a venous blood specimen shaking device for hospital laboratories, including a base, a guide rod, a screw rod, a lifting block, an arc-shaped claw, a shaking table, a rectangular translation frame, a driving motor, an incomplete gear, and a fixed collar. It is characterized in that: a lifting block is threadedly installed on the screw rod; the right end of the shaft sleeve is fixedly installed with a clamping force arm through a connecting rod, gears are provided on the front and rear sides inside the rectangular translation frame, and the gears inside the rectangular translation frame are adapted to the gears on the incomplete gear. The rear side of the rectangular translation frame is fixedly connected with a fixed collar through a connecting rod. In this patent, the blood collection tube is indirectly driven to move downward into the fixed collar by manually rotating the handwheel, so as to meet the shaking of blood collection tubes of different lengths. However, it can only achieve the left-right moving shaking of blood samples, with a poor shaking effect and a single shaking form, unable to meet different shaking requirements.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Usually, the components of the embodiments of the present invention described and shown in the accompanying drawings here can be arranged and designed in various different configurations.

[0024] Embodiment 1, in combination with the attached Figures 1-7 , an automatic blood shaking device for vascular surgery, including:

[0025] A shaking device, which is used to drive the blood collection tube to shake and mix the blood in the blood collection tube. The shaking device is driven by Motor 1 1;

[0026] A centrifugal rotation device, which is used to drive a blood collection tube to rotate along its own axis to shake the blood in the blood collection tube, and the centrifugal rotation device is driven by a second motor.

[0027] A chassis 2, in which a control processor is provided. A touch-screen operation panel 3 is embedded on the upper side of the chassis 2. A switch 4 is provided on the upper side of the chassis 2. The touch-screen operation panel 3 is electrically connected to the control processor through the switch 4. The first motor 1 and the second motor are electrically connected to the control processor.

[0028] The shaking device includes a driving disk 5, a transmission mechanism, and a blood collection tube placement rack 6. The driving disk 5 is rotatably connected to the chassis 2. The driving disk 5 is non-circular. The first motor 1 is installed directly above the driving disk 5 through a mounting bracket 25. The output shaft of the first motor 1 is connected to the center of the driving disk 5. The number of the transmission mechanisms is not less than 3. The transmission mechanism includes a slider 7, a guide rail 8, a first connecting rod 9, a second connecting rod 10, a spring 11, a sliding sleeve 12, and a fixed rod 13. A limiting groove 14 that is closed at the head and tail is provided along the edge of the bottom side of the driving disk 5. A guiding block 15 that is matched with the limiting groove 14 is fixedly provided at the end of the slider 7. The guiding block 15 moves along the limiting groove 14. The guide rail 8 is fixedly connected to the chassis 2. The slider 7 is slidably connected to the guide rail 8. The slider 7 is rotatably connected to the first connecting rod 9. The upper end of the first connecting rod 9 is rotatably connected to the lower end of the second connecting rod 10. The upper end of the second connecting rod 10 is connected to the upper end of the blood collection tube placement rack 6 through a spring 11. The second connecting rod 10 is slidably connected to the sliding sleeve 12. The sliding sleeve 12 is fixedly connected to the fixed rod 13. The fixed rod 13 is fixedly connected to the chassis 2. A plurality of blood collection tube insertion tubes 16 are provided on the blood collection tube placement rack 6. The control processor uses an STM32F103 microcontroller.

[0029] During use, select a suitable shaking form according to needs. When selecting shaking to mix evenly, insert the blood collection tube into the blood collection tube insertion tube 16, turn on the switch 4, and start the first motor 1 through the touch-screen operation panel 3. The first motor 1 drives the driving disk 5 to rotate. Under the action of each guiding block 15 and the limiting groove 14, each slider 7 is forced to reciprocally slide along its own guide rail 8, driving its own first connecting rod 9 to reciprocally move, and its own second connecting rod 10 to reciprocally lift. Under the action of a plurality of springs 11, the blood collection tube placement rack 6 shakes irregularly. By changing the rotation speed of the first motor 1, the shaking amplitude and speed of the blood collection tube placement rack 6 are changed, so as to shake the blood in the blood collection tube evenly.

[0030] Among them, the blood collection tube insertion tube 16 is made of rubber or silica gel, which can avoid damaging the blood collection tube. When made of rubber or silica gel, the inner diameter of the blood collection tube insertion tube 16 can be designed to be slightly larger than the outer diameter of the blood collection tube. At this time, it is convenient to place the blood collection tube, and the blood collection tube itself will also move within a certain range during the shaking of the blood collection tube placement rack 6, thereby further improving the shaking effect.

[0031] In this specific embodiment, the centrifugal rotation device includes a fixed disk 17, a central gear 18, and a driven gear 19. Blood collection tube clamping mechanisms are fixedly connected above both the central gear 18 and the driven gear 19. The fixed disk 17 is fixedly installed above the chassis 2 through a plurality of support rods 20. There are multiple driven gears 19. Both the central gear 18 and the driven gear 19 are rotationally connected to the fixed disk 17. The driven gear 19 meshes with the central gear 18. The rotating shaft of the central gear 18 extends from the lower side of the fixed disk 17 and is connected to the output shaft of the second motor. The main body of the second motor is arranged inside the chassis 2, and its output shaft extends from inside the chassis 2.

[0032] In this specific embodiment, the blood collection tube clamping mechanism includes a clamping bottom sleeve 21 made of rubber or silica gel. When in use, the blood collection tube is in interference fit with the clamping bottom sleeve 21. Above the clamping bottom sleeve 21, a retaining ring 23 is fixedly connected through a plurality of connecting rods 22. The inner diameter of the retaining ring 23 matches the outer diameter of the blood collection tube.

[0033] When using the centrifugal shaking method, insert the bottom end of the blood collection tube into the clamping bottom sleeve 21. The second motor rotates to drive the central gear 18 to rotate, and the driven gear 19 rotates, thereby driving all the blood collection tube clamping mechanisms to rotate. The blood collection tube rotates along its own axis to achieve the shaking effect. Among them, since the clamping bottom sleeve 21 is made of rubber or silica gel and the blood collection tube is in interference fit with the clamping bottom sleeve 21 when in use, clamping is achieved. And by setting the connecting rods 22 and the retaining ring 23, even if the blood collection tube accidentally detaches from the bottom sleeve 21, it will be limited by the connecting rods 22 and the retaining ring 23 and avoid being thrown off.

[0034] In this specific embodiment, both the first motor 1 and the second motor use ZWBPD006006 reduction motors.

[0035] In this specific embodiment, the number of transmission mechanisms is 4.

[0036] In this specific embodiment, support feet 24 are provided at the four corners of the lower part of the chassis 2 for easy placement.

[0037] In this specific embodiment, the support feet 24 are adjustable-height support feet. When placing, the height of each support foot 24 can be adjusted to make the chassis 2 placed horizontally.
