Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and specifically to a rotary pipette holder. Background Art

[0002] A pipette, also known as a pipetting gun, is a device used for quantitatively transferring liquids. When conducting research in analytical testing, a pipette is generally used to transfer small or trace amounts of liquid. In some medical experiments, a pipetting dispenser is usually required to transfer liquid samples. When using a pipette, a pipette holder is often used to place the pipette. Currently, the existing pipette holders on the market have a simple structure when in use, can hold a small number of pipettes, and do not have a rotatable structure. When the user needs to rotate the holder, the entire holder has to be picked up and rotated, which is rather troublesome to use and increases the operation time. When disinfecting the existing rotary holders, they are disinfected through a disinfection cabinet. However, the space in the disinfection cabinet is limited, making it difficult to place a relatively large rotary holder. Summary of the Invention

[0003] To solve the defect in the prior art that first installation is carried out, and then an external measuring device is used for angle measurement, which is time-consuming and laborious, the present invention provides a rotary pipette holder.

An identifier for identifying the identity of the RF card is fixedly provided on the bracket through a fixing frame. A controller is further provided on the socket. The controller is connected to the driving mechanism. A plurality of control buttons are provided on the outer wall of the bracket. By rotating the required pipette through the control buttons, the controller controls the driving mechanism to drive the rotation of the rotating shaft. Then, the identifier identifies the identity of the pipette on the telescopic frame until the required pipette is reached, and then the driving mechanism stops working.

The heating mechanism includes an electric heating tube provided on the side wall of the protective cover. A temperature sensor connected to the controller is provided on the protective cover. When the temperature sensor detects that the heating temperature reaches the set value, the controller controls the electric heating tube to heat.

The electronic components are avoided, so as to avoid damaging the electronic components.

[0015] 2. In this rotary pipette holder, a specific disassembly mechanism is set to disassemble and install the protective cover. The accurate docking is carried out through the cooperation of the positioning card and the positioning seat, and then it is fixed through the magnetic attraction fixing mechanism, so as to avoid accidental detachment. The magnetic attraction positioning mechanism includes a magnet provided on the positioning card and an electromagnet provided on the positioning seat. The magnetism generated after the electromagnet is energized is opposite to the magnetism of the magnet. In this way, the magnetic forces repel each other after being energized, which is convenient for removing the protective cover and convenient for subsequent use.

[0016] 3. In this rotary pipette holder, the heating mechanism and the disinfection mechanism are both integrated on the protective cover, which effectively reduces the mass and volume of the whole composed of the rotary rack and the bracket, and is convenient for handling and experimental operation.
