Detailed Description
The following description and the drawings sufficiently illustrate specific embodiments of the invention to enable those skilled in the art to practice them. Other embodiments may incorporate structural, logical, electrical, process, and other changes. The examples merely typify possible variations. Individual components and functions are optional unless explicitly required, and the sequence of operations may vary. Portions and features of some embodiments may be included in or substituted for those of others.
In some illustrative embodiments, as shown in fig. 1-3, a discharge head for modified PVC pellets for hemodialysis lines is provided, comprising: constant temperature water tank 1, oral siphon 2, outlet pipe 3, water pump 4, ejection of compact head foundry goods 5 and cover piece 6. The constant temperature water tank 1 is made of a metal water tank, and the water tank is coated with a heat insulation material. The outer surfaces of the water inlet pipe 2 and the water outlet pipe 3 are coated with heat insulation layers. The heat-insulating layer can be made of rubber-plastic sponge, polyethylene heat-insulating material and the like. The water pump 4 can be obtained by purchasing. The stub bar casting 5 and the cover member 6 are prepared by casting. The stub bar casting 5 and the cover member 6 are fixedly connected to one body by bolts.
