Description

Technical Field

[0001] The utility model relates to the technical field of mixing equipment, in particular to an automatic mixing device for blood collection tubes. Background Art

[0002] Blood tests are currently a common means of disease diagnosis and physiological index testing. Blood samples are usually collected using blood collection tubes during the blood drawing process. The blood collection tube is a disposable, negative pressure vacuum glass tube that can achieve quantitative blood collection. It needs to be used with a venous blood collection needle. According to different test requirements and purposes, the blood collection tubes are divided into 9 types using the color of the head cap (light blue, black, golden yellow, red, light green, green, purple, pearl white and gray). Different additives are added to blood collection tubes with different head cap colors. After completing the blood sample collection, medical staff need to gently invert the blood collection tube to mix it according to the mixing requirements corresponding to the different color head caps.

[0003] At present, the mixing of blood collection tubes is usually done manually by medical staff. Due to the different strengths and frequencies of inversion and mixing by medical staff, the quality of the mixing of blood collection tubes varies, affecting the accuracy of subsequent blood tests. In addition, medical staff need to mix a large number of blood collection tubes every day. Relying on manual mixing for a long time puts a heavy burden on medical staff, is time-consuming and labor-intensive, and greatly reduces work efficiency.

[0004] After searching, it was found that a vacuum blood collection tube mixing device was disclosed in a Chinese patent with the authorization application number CN202021884346.X, including a device body, the device body including a support frame, a motor and a vacuum tube placement plate, the support frame including a main support, an auxiliary frame, a base and a fixed hinge shaft, the motor including a timer, a lifting rod and a connecting rod, and the vacuum tube placement plate including a baffle, a chassis and a test tube clamp. The vacuum blood collection tube mixing device is provided with a motor on the right side of the device body, and a lifting rod is installed on the left side of the motor. The lifting rod is used to drive the entire vacuum tube placement plate to obtain an effective motion trajectory, so that the inside of the vacuum tube can obtain the beneficial effect of mixing. By providing a test tube on the vacuum tube placement plate and fixing the vacuum blood collection tube with a test tube clamp, the vacuum tube can effectively and stably mix the beneficial effect.

[0005] However, the above technical solution still has the following defects: since the mixing requirements of different colored skull blood collection tubes are different, the mixing effect of different blood collection tubes cannot be guaranteed during mixing. Utility Model Content

[0006] In view of the above situation, in order to overcome the defects of the prior art, the purpose of the utility model is to provide an automatic mixing device for blood collection tubes, which effectively solves the problems of high mixing load and low efficiency of blood collection tubes and poor mixing effects of different blood collection tubes.

[0007] The technical solution is that the utility model includes a box seat, the upper surface of which is provided with a plurality of mounting grooves evenly distributed in the horizontal direction, two left-right symmetrical support seats are arranged in the mounting grooves, the opposite surfaces of the two support seats are hinged with steering shafts, a rocker arm passes through the steering shaft, the bottom end of the rocker arm is located in the box seat, a driving mechanism is arranged at the bottom end of the rocker arm, the top end of the rocker arm is located outside the box seat, a mixing box is fixedly connected to the top end of the rocker arm, a plurality of the mixing boxes are made of different colors, and a carrying box for placing blood collection tubes is slidably connected to the inner wall of the mixing box.

[0008] Compared with the prior art, the utility model has an ingenious structure and is easy to operate. Through the cooperation of the swing rod, the mixing box and the carrying box, the mixing effect of the blood collection tube is effectively improved, and the corresponding mixing scheme is adopted according to the mixing boxes of different colors. The operation is simple and efficient, and the practicality of use is greatly improved. Through the cooperation of the motor, the driving gear, the driven gear, the swing rod and the steering shaft, the swing rod moves according to a certain trajectory, and the control is more convenient and efficient, which is conducive to improving the mixing quality.

Through the elastic force of the tension springs 17 between the mixing box 6 and the box body 8, a good buffering effect can be achieved during the movement of the box body 8, which is conducive to improving the safety of the box body 8 when sliding.

[0025] In order to achieve the effect of stable movement of the swing rod 5, the driving mechanism includes a fixing frame 18 fixedly connected to the inner bottom wall of the box seat 1, a driven gear 19 is rotatably mounted on the top of the fixing frame 18, and the bottom end of the swing rod 5 is hinged on the driven gear 19. A groove for rotatably mounting the driven gear 19 is formed at the top of the fixing frame 18, and the driven gear 19 is rotatably mounted on the fixing frame 18 through the groove, and a protrusion for hingedly connecting the swing rod 5 is formed on the surface of the driven gear 19. Through the rotational cooperation between the driven gear 19 and the fixing frame 18 and the hinged cooperation between the driven gear 19 and the swing rod 5, the driven gear 19 rotates to drive the swing rod 5 to move, thereby driving the blood collection tube to move, which is conducive to improving the mixing speed.
