Embodiment Construction

[0025] The following describes the present invention in further detail based on the drawings and embodiments:

[0026] As shown in the figure, the sampling needle cleaning device 11 of this embodiment includes a main body 6, an outlet connector 8 and an inlet connector 4, and a mandrel 7. The cavity is located at the center of the mandrel 7 and penetrates up and down. The cavity 2 passes through the channel 9 and the outlet. The connecting pipe 8 communicates, and the axis of the passage 9 coincides with the axis of the connecting pipe 8; the cavity 3 is connected to the inlet pipe 4 through the passage 11, and the axis of the passage is perpendicular to the axis of the inlet pipe 4 when the passage 11 has two. The inlet and outlet nozzles are installed on the main body 6, and the installation holes 15, 16 and the main shaft 7 installation holes of the main body 6 cooperate to form the cavities 12, 13 connecting the nozzles 4, 8 and the channels 9, 11, so that the fluid can flow s...

Abstract

The invention provides a device for washing a sampling needle of a hematology analyzer. The device is characterized by comprising a main body, a liquid inlet pipe, a liquid outlet pipe and a central spindle, wherein the central spindle is provided with a chamber which is axially penetrated; the liquid inlet pipe and the liquid outlet pipe are installed on the main body; the included angle of the liquid inlet pipe and the liquid outlet pipe is 90 degrees; the central spindle is installed at the center of the main body; and the chamber in the central spindle is communicated with the liquid inlet pipe and the liquid outlet pipe via a side passage on the central spindle. The washing device provided by the invention has good effect of washing the sampling needle under the condition of reducingthe quantity of rinsing liquid and the power of a negative pressure pump, thereby improving the adaptability of a machine to the environment.

Description

Technical field [0001] The invention belongs to the field of blood cell analysis equipment and is a device for cleaning the sampling needle of a blood analyzer. Background technique [0002] In the blood cell analysis instrument, the blood sample is drawn from the test tube by the sampling needle. In order to avoid the pollution of the next test, the inner and outer surfaces of the sampling needle need to be cleaned to remove the blood samples remaining inside and outside the sampling needle, and ensure thorough cleaning . The sampling needle cleaning device is a device with the function of cleaning the outer wall of the sampling needle. [0003] At present, the cleaning method adopted by various blood analysis instruments is to use a cleaning system to flush the sampling needle with a flowing cleaning fluid, and take the cleaning fluid and the blood sample away from the cleaning device. The working process of this cleaning system is as follows, software and hardware Control the ...
