AI Technical Summary
The connector of the existing hemodialysis machine testing and calibration instrument is easily damaged by external impacts and can easily get dust and bacteria in, affecting the accuracy of the test results.
A protective structure was designed, including a liquid inlet pipe, a fixed plate, a shut-off valve, a diamond-shaped block, a pull-out plate, an iron plate, a silicone sheet, a slot, a connector, and a pull ring. The pull-out plate protects the connector by pulling it out and resetting it, and the silicone sheet seals the connector opening to reduce the entry of dust and bacteria.
This effectively prevents external impacts on the connector, ensures the connector opening is sealed, reduces the entry of dust and bacteria, and improves the accuracy of test results and the hygiene and safety of the instrument.
