Description

Technical Field

[0001] This utility model belongs to the field of centrifuge testing technology, specifically relating to a centrifuge support assembly. Background Technology

[0002] Medical centrifuges utilize centrifugal force and buoyancy density differences to separate, concentrate, and purify various components in biological samples, finding wide application in biology, clinical medicine, and laboratory medicine. In the life sciences, the separation and purification of cells, organelles, and proteins require low-temperature conditions. In medicine, the separation and culture of platelets and white blood cells, as well as viruses and bacteria, also necessitate low-temperature environments in centrifuges. Furthermore, the development of plasma protein preparations requires centrifuges with low-temperature capabilities. Temperature is a crucial technical indicator affecting the centrifugation effect.

[0003] Centrifuge rotors come in many types, and the centrifuge tubes used with them vary in diameter, as do the number, diameter, and depth of the rotor holes. Currently, centrifuge temperature measurement mainly focuses on the temperature near the temperature control sensor or the temperature when the centrifuge is not rotating. This temperature does not match the temperature during normal centrifuge operation. According to calibration specifications and actual usage requirements, it is necessary to dynamically measure the temperature at the location where the centrifuge tubes are placed inside the centrifuge rotor to measure the true temperature of the sample during rotation. The temperature control sensor and other accessories are integrated into a temperature calibrator, which is connected to the centrifuge tubes. Due to the high-speed operation of the centrifuge, the temperature calibrator needs to be installed and secured. However, each installation and removal of the temperature calibrator requires tools to tighten the bolts in a dedicated mounting bracket, making the installation and securing method very inconvenient for operators.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A centrifuge support assembly, comprising:

[0006] The central rotating frame can be fitted onto the centrifuge shaft;

[0007] A container for holding the temperature calibrator;

[0008] At least one pair of limiting units are symmetrically distributed on both sides of the central rotating frame. Each limiting unit includes limiting arms located on both sides of the placement container. The placement container and the limiting arms have a limiting structure, and the placement container is detachably connected to the limiting arms through the limiting structure.

[0009] Furthermore, the limiting structure includes a slot that extends vertically inside the limiting arm and a protruding ridge that is provided on the side of the container and conforms to the slot.

[0010] Furthermore, the limiting structure includes a protruding ridge that extends vertically inside the limiting arm, and a slot that has the side portion of the container and conforms to the protruding ridge.

[0011] Furthermore, the slot is a dovetail groove.

[0012] Furthermore, at least one of the slots and / or protrusions is configured as two sets.

[0026] like Figure 1 - Figure 3 As shown, a centrifuge support assembly of the present invention includes a central rotating frame 1, a placement container 2, and a limiting unit;

[0027] The central rotating frame 1 can be sleeved onto the centrifuge shaft;

[0028] Container 2 is used to place the temperature calibrator 5;

[0029] At least one pair of limiting units are provided and symmetrically distributed on both sides of the central rotating frame 1. The limiting unit includes limiting arms 30 located on both sides of the placement container 2. There is a limiting structure between the placement container 2 and the limiting arms 30. The placement container 2 is detachably connected to the limiting arms 30 through the limiting structure.

[0030] By setting limit units that are symmetrically connected to both sides of the central rotating frame 1, the container 2 and its temperature calibrator 5 are kept in balance under the action of centrifugal force.

[0031] The container 2 and the limiting arm 30 are detachably connected. Unlike existing fixed brackets, the limiting structure does not require additional tools to operate, making it more convenient to use.

[0032] like Figure 2 As shown, the limiting structure includes a slot 31 that extends vertically inside the limiting arm 30, and a protrusion 32 that is provided on the side of the container 2 and conforms to the slot 31.

[0033] The limiting structure can also interchange the positions of the protrusion 32 and the slot 31. Specifically, the protrusion 32 is opened on the inside of the limiting arm 30 and extends vertically, while the slot 31 is opened on the side of the container 2 and conforms to the shape of the protrusion 32.

[0034] Specifically, slot 31 is a dovetail groove. This design makes the limiting structure more robust. Of course, slot 31 can also adopt other design forms, and there are no specific restrictions.

[0035] At least one of the slots 31 and / or the protrusions 32 is configured as two sets.

[0036] When multiple temperature calibrators 5 are installed in the container 2, in order to increase the connectivity of the limiting unit to the container 2, the slots 31 and protrusions 32 can be set into two sets.

[0037] However, when installing a smaller number of temperature calibrators 5, one of the slots 31 and the protrusions 32 can be set to one, while the other can be set to two. In this way, the position of the container 2 can be adjusted, changing the distance between the container 2 and the central rotating frame 1, without losing the connection between the limiting unit and the temperature calibrator 5.

[0038] In actual use, the temperature calibrator 5 to be tested is inserted into the placement container, and the two placement containers 2 are combined with the limiting unit respectively. Specifically, the protrusions or slots on the side of the placement container 2 are symmetrical with the slots or protrusions of the limiting arm, and the placement container is vertically inserted between the two limiting arms.

[0039] The limiting unit is connected to the outer periphery of the central rotating frame 1 via the connecting arm 40.

[0040] A reinforcing rib 41 is connected between two adjacent limiting units.

[0041] In this embodiment, there are two pairs of limiting units, which are arranged around the central frame.

[0042] The temperature calibrator 5 includes a housing 50, a circuit board 51 located inside the housing 50, an intelligent module mounted on the upper surface of the circuit board 51, and a probe 52 mounted on the bottom plane of the circuit board 51. A centrifuge tube 53 is located on the outer periphery of the probe 52.

[0043] The top of the probe 52 is soldered to the bottom plane of the circuit board 51. The probe 52 has a metal protective layer on the outside and a platinum resistance thermometer inside. The upper end is provided with a step and is embedded in the housing 50. The embedded length is not less than 1 / 3 of the total length of the probe 52 to ensure that the probe 52 will not bend under high speed conditions.

[0044] The temperature measuring end of probe 52 is inserted into centrifuge tube 53 and comes into contact with the sample to be tested.

[0045] It should be noted that, in order to accommodate centrifuge rotors of different specifications, the temperature calibrator 5 is equipped with nestable fixing devices of different specifications, including but not limited to 5mL, 10mL, 15mL, 30mL, 50mL, and 100mL.

[0046] Nestable fixing devices may include a single nestable unit or two nested units, which can be used in combination to accommodate rotors ranging from a minimum of 1.5 μm to a maximum of 1 L.

[0047] The nestable fixing device includes a first nestable unit 60 fitted outside the centrifuge tube 53 and a second nestable unit 61 fitted outside the first nestable unit 60.

[0048] When the temperature calibrator 5 is installed in the placement container 2, the centrifuge tube 53 is inserted into the placement hole 20 opened in the placement container 2. Through the action of the fixing device, the outer wall of the temperature calibrator 5 is tightly fitted with the inner wall of the placement hole 20. Specifically, a sealing ring 62 is fitted around the outer periphery of the fixing device.

[0049] The aforementioned fixing device and temperature calibrator 5 are existing technologies. For specific structures and connection methods, please refer to the technical solution mentioned in application number CN202322546525.2. The aforementioned structures are not within the protection scope of this application.
