Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and specifically refers to a medical blood collection and mixing device. Background Art

[0002] Blood routine tests are often used as an auxiliary means for disease diagnosis. The content of various microorganisms and related cells in the blood can accurately reflect the human body's condition. Therefore, after the blood collection work of the patient is completed, a mixing device is required to ensure that blood cells, plasma, and other components in the blood sample are quickly and fully mixed after collection to improve the accuracy of subsequent tests.

[0003] Currently, most medical institutions mix by hand by blood collection personnel. However, large quantities of blood need to be collected and tested every day in medical institutions, and manual mixing seriously affects the testing efficiency. Some medical institutions will use blood mixing devices to process blood samples. However, most of the existing mixing devices rotate around the axis in a single dimension, unable to fully mix the blood evenly, and most of these mixers have complex structures, high failure rates, are not easy to repair, and rely on power sockets, with great limitations. Summary of the Invention

On both sides of the center of the fixed shaft core, there are anti-slip part grooves, and a positioning groove is arranged in the center of the anti-slip part grooves. The anti-slip part grooves only penetrate through the blood collection tube grooves II and leave through holes in the blood collection tube grooves II.

[0009] Further, a central column is arranged in the center of the blood collection tube anti-slip part. The side wall of the central column is circularly arrayed with pressure springs, and anti-sliding blocks are arranged at the ends of the pressure springs.

A gear positioning column is arranged inside the gear ring, and the gear positioning column is magnetically attracted to the bottom plate of the rotating bin. A ring groove is arranged at the outer edge of the bottom plate of the rotating bin.

[0012] Further, the driving assembly includes a driving shaft, a rotating part and a connecting gear. The driving shaft is arranged in the central shaft sleeve.

[0041] The driving assembly 3 includes a driving shaft 31, a rotating part 32 and a connecting gear 33. The driving shaft 31 is arranged in the central shaft sleeve 21. The rotating part 32 is connected between the driving shaft 31 and the mixing tank 11. A driving helical gear 312 is arranged at one end of the driving shaft 31, and a motor 311 is arranged at the other end of the driving shaft 31. The driving helical gear 312 is located inside the rotating bin 2, and the motor 311 is located outside the rotating bin 2.

[0043] The fixed base 4 is provided with a rotating bin fixing cylinder 41, a load-bearing base 42 and a rear back plate 43. The rotating bin fixing cylinder 41 is arranged on the load-bearing base 42, and the rear back plate 43 is arranged at the rear of the rotating bin fixing cylinder 41. The rotating bin 2 rotates in the rotating bin fixing cylinder 41. A positioning ring protrusion 411 is arranged at the bottom of the rotating bin fixing cylinder 41, and the ring groove of the bottom plate of the rotating bin 2 is clamped on the positioning ring protrusion 411.

[0044] A motor fixing rod 421 is arranged inside the rear of the load-bearing base 42, the motor 311 is fixed on the motor fixing rod 421, and the load-bearing base 42 is also provided with a switch, a charging hole and a storage battery. A heat dissipation groove is arranged on the rear back plate 43.

[0045] During specific use, medical staff place the blood collection tube containing blood into the blood collection tube slot 111 of the mixing tank 11. As the blood collection tube is inserted into the blood collection tube slot 111, when the bottom of the blood collection tube touches the anti-slip block 131, it will squeeze the anti-slip block 131 along the inclined surface of the anti-slip block 131, causing the anti-slip block 131 to compress the pressure spring 132 and slide into the anti-slip part slot 122. Under the elastic force of the pressure spring 132, the friction between the anti-slip block 131 and the blood collection tube is increased, thereby fixing the blood collection tube and preventing it from falling off.

[0046] After the blood collection tube is fixed, the switch is turned on, and the motor 311 starts, driving the drive shaft 31 to rotate. The drive helical gear 312 on the drive shaft 31 drives the helical gear 324 of the rotating part 32 to rotate, and then the engaging plate 323 of the rotating part 32 rotates. The engaging plate 323 pushes the engaging column 115 of the mixing tank 11 and causes the mixing tank 11 to rotate. During the rotation of the mixing tank 11, the front protrusion 321 of the rotating part 32 slides in the sliding groove 114 of the mixing tank 11, and the rear protrusion 322 of the rotating part 32 is arranged in the rotating part positioning hole 211 of the central shaft sleeve 21. Under the guidance of the sliding groove 114, the rotating part 32 drives the mixing tank 11 to rotate back and forth, and also causes the mixing tank 11 to reciprocate along the axis direction of the bottom rotating shaft 113. The bottom rotating shaft 113 at the bottom of the mixing tank 11 slides up and down in the rotating shaft sliding sleeve 22 of the rotating chamber 2.

[0047] During the rotation of the drive shaft 31, the drive gear 313 on the drive shaft 31 drives the connecting gear 33 to rotate, the connecting gear 33 drives the gear ring 23 to rotate, and the gear ring 23 drives the rotating chamber 2 to rotate. The mixing tank 11 rotates driven by the rotating chamber 2. Then, the blood collection tube will not only rotate with the self-rotation of the mixing tank 11, but also reciprocate along the axis direction of the bottom rotating shaft 113 with the rotating mixing tank 11, oscillating the blood inside the blood collection tube. At the same time, the mixing tank 11 will also rotate with the rotating chamber 2, thereby achieving the technical effect of fully mixing the blood inside the blood collection tube. After full mixing, the switch is turned off, and medical staff draw out the blood collection tube and replace it with another batch of blood collection tubes containing blood for mixing. The device is equipped with a storage battery, enabling the device to be used anytime and anywhere without relying on a power socket. The heat dissipation slots on the back plate 43 prevent the device from overheating and prevent the temperature from affecting the results of blood tests.
