This utility model discloses a salt leg device, comprising a salt leg body, a feed inlet at the top of the salt leg body, a discharge outlet at the lower middle part of the salt leg body, a return outlet, a first washing outlet, a second washing outlet, a vent at the bottom of the salt leg body, and a venting and rinsing outlet on the bottom side wall; the discharge outlet is located above the return outlet, and the discharge outlet and return outlet are distributed on both sides of the salt leg body, the front end of the discharge outlet is a downward sloping bevel, and the front end of the return outlet is an upward sloping bevel; the first washing outlet is located above the discharge outlet, the second washing outlet is located below the return outlet, and the first washing outlet and the second washing outlet are distributed on both sides of the salt leg body, the front end of the first washing outlet is a downward sloping bevel, and the front end of the second washing outlet is an upward sloping bevel; the venting and rinsing outlet is located below the second washing outlet. This utility model aims to solve the problem of easy clogging in salt leg devices.

This invention discloses a rapid human interleukin-4 test strip based on a double-antibody sandwich method. The test strip includes a sample pad, a latex pad, a conjugate pad, a nitrocellulose membrane, and an absorbent pad. The latex pad is made of latex microspheres labeled with CKIgY monoclonal antibody and red polystyrene latex microspheres. The conjugate pad is made of latex microspheres labeled with IL-mouse monoclonal antibody and red polystyrene latex microspheres. A detection line and a control line are located in the center of the nitrocellulose membrane. The detection line contains a protein conjugate for binding with the IL-mouse monoclonal antibody, and the control line contains an IgG monoclonal antibody. An upper shell is located on the outside of the test strip, and a matching lower shell is provided. This invention provides a rapid human interleukin-4 test strip based on a double-antibody sandwich method. This test strip has high sensitivity, low risk of cross-reaction, simple operation, and low cost.

The present application provides a dialysis device and a priming method of the dialysis device. The operation time of priming can be shortened. The present application relates to a dialysis device provided with a connection passage (blood return passage, replacement fluid passage) for connecting a dialysate circuit and a blood circuit, and allowing dialysate to flow from the dialysate circuit to the blood circuit through the connection passage during priming operation. The blood pump is provided with a tube mounting unit capable of switching from an uninstalled state in which a tube is located outside a housing and liquid can flow inside to an installed state in which the tube is accommodated in the housing and the tube is pressed by the rotor. During priming operation, dialysate is caused to flow from the dialysate circuit to the blood circuit through the connection passage by the liquid delivery pump, and the blood pump is set to the uninstalled state to allow dialysate to flow past the blood pump, and the blood pump is set to the installed state to allow dialysate to flow in the opposite direction of the blood pump.
