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 application discloses a method for manufacturing a spherical crown part by using a single-point incremental forming technology, and comprises the following steps: step 1, determining basic forming parameters according to material performance and a target shape; step 2, performing first-pass forming according to a first-pass path, the forming depth is less than the target depth, and an axial compensation amount is reserved; step 3, performing second-pass forming according to a second-pass path on the basis of step 2, so that the radial direction approaches the final profile, and the depth direction reaches the target depth; and step 4, performing third-pass forming according to a third-pass path from the bottom of the spherical crown part to the edge direction of the top on the basis of step 3, so that the spherical crown part is obtained. The application solves the problems of breakage and low precision of existing alloys in the process of single-point incremental forming of a deep-cavity spherical crown part.

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.

The invention relates to the technical field of pole columns, and discloses an eccentric pole column forming method which comprises the following forming methods: 1) providing a bar material, and bending the bar material to form a bent bar which comprises a transverse section and a longitudinal section; (2) the longitudinal section is extruded to form a cylinder section, and the transverse section is extruded and lengthened to form a lengthened section; (3) forging and pressing the lengthened section to form a flat plate section, and forging and pressing and lengthening the column body section to form a column head; 4) forging and shaping the column head; (5) cutting the periphery of the flat plate section to form a plate body column head and a plate body which are eccentrically arranged to form an eccentric pole column; through multiple times of forging and pressing, the material flowing direction is controlled in the forging and pressing process, the material utilization rate is increased, and the forming cost of the eccentric pole is reduced.
