Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary device technology, specifically an automatic shaking device for blood sampling tubes. Background Technology

[0002] In hospitals, it is often necessary to draw blood from patients. After drawing blood, some special sampling tubes need to be shaken to facilitate subsequent testing and treatment. However, the current method of shaking the sampling tubes is basically manual. This method can only shake one sampling tube at a time, which is very inefficient. When there are too many tubes to shake, one person cannot handle it and it is difficult to control the shaking time and force, resulting in poor blood mixing.

[0003] Patent CN220294560U discloses an automatic blood sampling tube shaking device, including a base. A shaking mechanism and a holding mechanism are located above the base. The shaking mechanism includes a support plate inside the base. The base has a U-shaped structure. A support block is fixedly connected to the upper left end of the base. A motor is located inside the support block, and a rotating shaft is connected to the motor's output end. A protrusion is fixedly connected to the outer surface of the rotating shaft. The support plate is located inside the base. This technology can automatically shake a large number of blood sampling tubes at once, resulting in high work efficiency and effectively reducing the workload of medical staff. By placing the sampling tube into the placement hole (inner groove), the external clamping pad comes into contact with the sampling tube, thus clamping it. It can be used to shake various types of sampling tubes, has a wider range of applications, and facilitates the placement and removal of sampling tubes.

[0004] However, the above technology still has the following problems:

[0005] The force and frequency of spring shaking can be difficult to control precisely, resulting in inconsistent mixing of blood samples in different blood collection tubes and affecting the accuracy of subsequent tests. Using spring shaking for mixing requires certain operating skills and experience; otherwise, the desired mixing effect may not be achieved. The spring shaking may generate significant impact force, which could cause the test tube rack or blood collection tubes to tip over or rupture if the rack or tubes are not securely fixed, leading to blood sample contamination and waste, and potentially even injury to the operator. Furthermore, as a consumable part, the spring may fail due to fatigue after prolonged use and require replacement. Utility Model Content

[0006] To address the shortcomings of existing technologies, this invention provides an automatic shaking device for blood collection tubes, which can be adapted to blood collection tubes of various sizes and ensures excellent shaking effect.

[0007] This utility model provides the following technical solution: an automatic shaking device for blood sampling tubes, including a base plate, a support leg fixedly connected to the lower end of the base plate, a support plate one and a support plate two fixedly connected to the two sides of the upper surface of the base plate respectively, a driver fixedly connected to the support plate one, a rotating shaft fixedly connected to the output end of the driver, the rotating shaft being rotatably connected to both the support plate one and the support plate two, a U-shaped plate fixedly connected to the middle part of the rotating shaft, a fixing mechanism for fixing the blood collection tube fixedly connected to the U-shaped plate, insertion holes opened on both sides of the upper end of the U-shaped plate, a tightening bolt one threadedly connected to the U-shaped plate, the front end of the tightening bolt one being located in the insertion hole, a protective mechanism detachably connected to the insertion hole, and an auxiliary support mechanism fixedly connected to the base plate.

[0012] Furthermore, the insertion rod has a groove.

[0013] Furthermore, the auxiliary support mechanism includes an outer rod fixedly connected to the base plate, with sliding cavities at both ends of the outer rod, and an L-shaped inner rod slidably connected in each of the two sliding cavities.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Please see Figures 1 to 6 An automatic blood sampling tube mixing device includes a base plate 1. A support leg 2 is fixedly connected to the lower end of the base plate 1. A support plate 3 and a support plate 4 are fixedly connected to both sides of the upper surface of the base plate 1, respectively. A driver 5 is fixedly connected to the support plate 3. A rotating shaft 6 is fixedly connected to the output end of the driver 5. The rotating shaft 6 is rotatably connected to both the support plate 3 and the support plate 4. A U-shaped plate 7 is fixedly connected to the middle part of the rotating shaft 6. A fixing mechanism for fixing the blood collection tube is fixedly connected to the U-shaped plate 7. Insertion holes 8 are opened on both sides of the upper end of the U-shaped plate 7. A tightening bolt 9 is threadedly connected to the U-shaped plate 7. The front end of the tightening bolt 9 is located in the insertion hole 8. A protective mechanism is detachably connected to the insertion hole 8. An auxiliary support mechanism is fixedly connected to the base plate 1.

[0025] The automatic blood sampling tube shaking device in this utility model is structurally similar to existing automatic blood sampling tube shaking devices, such as the one disclosed in patent CN220294560U. The main improvement of this utility model is that it can fix blood collection tubes of different sizes and shake the blood sample by flipping it, without damaging the blood sample. Figures 1 to 6As shown, in use, the automatic shaking device for blood sampling tubes of this utility model first rotates the tightening bolt 9 to release the restriction on the protective mechanism, thereby disassembling the protective mechanism. Then, the blood sampling tube is inserted into the round hole 11 on the fixing plate 10. The rubber block 12 deforms under force, thereby squeezing and fixing the blood sampling tube. The lower end of the blood sampling tube is located on the cotton pad 22 in the placement groove 21. Then, the insertion rod 14 on the protective mechanism is placed in the insertion hole 8 until the rubber pad 15 on the lower surface of the cover plate 13 contacts the upper end of the blood sampling tube. Tighten the tightening bolt 9 to fix the insertion rod 14, thereby fixing the position of the cover plate 13. Then, release the restriction of the tightening bolt 20 on the L-shaped inner rod 19 and pull the L-shaped inner rod 19 outward. At this time, the driver 5 is driven. The driver 5 rotates the rotating shaft 6, thereby causing the U-shaped plate 7 to rotate, thereby flipping the blood sampling tube on the fixing mechanism, thereby shaking the blood sample inside the blood sampling tube to facilitate subsequent testing.

[0026] It should be noted that two fixing mechanisms can be set on the U-shaped plate 7, which can further improve the fixing effect on the blood collection tube.

[0027] like Figure 1 or Figure 2 As shown, the driver 5 is a variable frequency speed control motor or a continuously variable speed motor.

[0028] Specifically, the variable frequency speed control motor or the continuously variable speed motor can adjust the rotation speed of the rotating shaft 6, thereby adjusting the flipping speed of the blood collection tube, which in turn can adjust the shaking speed of the blood sample.

[0029] like Figure 5 As shown, the fixing mechanism includes a fixing plate 10 fixedly connected to the U-shaped plate 7. The fixing plate 10 has a plurality of equally spaced circular holes 11, and a plurality of circumferentially arrayed rubber blocks 12 are fixedly connected to the inner wall of the circular holes 11.

[0030] Specifically, the blood sampling tube is inserted into the round hole 11 on the fixing plate 10, and the rubber block 12 is deformed by force, thereby squeezing and fixing the blood sampling tube.

[0031] like Figure 6 As shown, the bottom wall of the U-shaped plate 7 is provided with several placement grooves 21 that are adapted to the round holes 11, and cotton pads 22 are fixedly connected to the inner wall of the placement grooves 21.

[0032] Specifically, the lower end of the blood sampling tube is placed on the cotton pad 22 in the placement slot 21, which can support and protect the lower end of the blood sampling tube.

[0033] like Figure 3As shown, the protective mechanism includes a cover plate 13, with a plug rod 14 adapted to the plug hole 8 fixedly connected to the lower end of the cover plate 13, and a rubber pad 15 fixedly connected to the lower surface of the cover plate 13.

[0034] Specifically, after placing the blood collection tube on the fixing mechanism, the insertion rod 14 is placed in the insertion hole 8 until the rubber pad 15 on the lower surface of the cover plate 13 contacts the upper end of the blood collection tube. Then, the tightening bolt 9 is tightened to fix the insertion rod 14, thereby fixing the position of the cover plate 13. This can prevent the loosely fixed blood collection tube from falling when it is flipped over, thus preventing damage to the blood sample. At the same time, the position of the cover plate 13 can be changed to accommodate blood collection tubes of different heights.

[0035] like Figure 3 As shown, the insertion rod 14 has a groove 16.

[0036] Specifically, the front end of the tightening bolt 9 abuts against the inner wall of the groove 16, which increases the contact area and thus strengthens the fixing effect of the tightening bolt 9 on the insertion rod 14 and the cover plate 13. At the same time, the lower inner wall of the groove 16 can also abut against the threaded groove of the tightening bolt 9, preventing the insertion rod 14 from sliding off from the upper end of the insertion hole 8.

[0037] like Figure 4 As shown, the auxiliary support mechanism includes an outer rod 17 fixedly connected to the base plate 1. Both ends of the outer rod 17 are provided with sliding cavities 18. An L-shaped inner rod 19 is slidably connected in both sliding cavities 18. Both ends of the upper surface of the outer rod 17 are threaded with tightening bolts 20 for fixing the L-shaped inner rod 19.

[0038] Specifically, by releasing the restriction of the L-shaped inner rod 19 by the tightening bolt 20, the L-shaped inner rod 19 is pulled outward, and the front end of the L-shaped inner rod 19 extends outward, thereby increasing the stability of the device operation.

[0039] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
