[0002] As an instrument for collecting blood samples, hemorheometers are widely used in the field of medical devices. The hemorheometers currently used in the market are clinically used because some blood samples themselves contain thrombus or blood clots. At the same time, as the operator of the instrument It is said that the blood sample is not mixed enough during operation, which is easy to form clots, which leads to the blockage of the sampling pipeline of the hemorrhage meter

The invention provides a device and method for treating blockage in pipelines of a full-automatic blood rheometer. The device comprises a sampling needle which is used for extracting and collecting a sample in a sample tank, wherein a sampling needle pipe sleeve is inserted into one end of a sampling pipeline, the other end of the sampling pipeline is connected with one end of a starting valve, the other end of the starting valve is connected with a first end of a four-way valve, a pressure sensor is installed inside the four-way valve, a second end of the four-way valve is connected with one end of a control valve, the other end of the control valve is connected with one end of a washing connector, the other end of the washing connector is connected with one end of a washing pump, the other end of the washing pump is connected with a first end of a first three-way valve, and a second end of the first three-way valve is connected with a washing tank; a single chip microprocessor controller controls a corresponding pump body and sensor. The pressure sensor is used for monitoring the blockage condition of the pipeline, the pressure value of the pressure sensor is analyzed and judged in real time by virtue of a control system, so that the working safety and high efficiency of the blood rheometer can be guaranteed, the detection precision is improved, and the service life of the device is prolonged.
Description
technical field [0001] The invention relates to the field of medical equipment automation, in particular to a device and method for treating blockage of a pipeline of an automatic blood rheometer. Background technique [0002] As an instrument for collecting blood samples, hemorheometers are widely used in the field of medical devices. The hemorheometers currently used in the market are clinically used because some blood samples themselves contain thrombus or blood clots. At the same time, as the operator of the instrument It is said that the blood sample is not mixed enough during operation, which is easy to form clots, which in turn leads to blockage of the sampling pipeline of the hemorheometer. In addition, due to incomplete daily cleaning and maintenance, and insufficient maintenance of the instrument, a large amount of protein and lipid adhesion will be left behind, resulting in a false increase in the viscosity test, resulting in inaccurate test results. This just ne...
