Description

Anti-drop protective cover for hemodialysis machine

Technical Field

The utility model relates to the technical field of hemodialysis devices, in particular to an anti-falling protective cover for a hemodialysis device.

Background

At present, almost all dialyser blood and dialyser fluid inlets and outlets are provided with protective covers, and the protective covers designed by various manufacturers are different, and are mainly divided into screw threads, stripes and size matching modes according to the fastening modes of the protective covers. However, in terms of the anti-falling aspect, the manufacturers of the existing related designs are less, and only a small part of high-end products have the anti-falling capability due to the design of the internal threads.

In practice, there is a risk that the protective cover will fall off both during production and during use of the dialyzer product, which risk is small overall, since the problem is very easy to find before use, and thus does not affect the patient, but still causes a certain loss to the manufacturer. The risk of falling off in production mainly comes from sterilization, and the air current that will have in the sterilization process strikes the visor, causes the risk of falling off. The protection cover may be removed during the subsequent transportation, and the protection cover may be removed during the use due to the impact of water flow during the pre-filling and the influence of gravity of the liquid after the use.

In addition, as for materials, the protection covers of most manufacturers mainly use High Density Polyethylene (HDPE), low Density Polyethylene (LDPE), polypropylene (PP), etc., and the differences in materials, shapes and thicknesses can lead to differences in appearance color and product hardness. HDPE is a high crystallinity, nonpolar thermoplastic resin having a melting point of about 130℃and a relative density of 0.941 to 0.965g/cm3. The LDPE has the relative density of 0.910-0.925 g/cm < 3 >, lower crystallinity and softening point, better softness, elongation, electrical insulation, transparency and higher impact strength. PP has a large molecular weight difference according to the degree of polymerization, and is generally classified into three configurations of isotactic polypropylene, atactic polypropylene and syndiotactic polypropylene. Most of common PP used for protective covers is isotactic polypropylene, and the density is 0.90-0.91 g/cm < 3 >. We have devised an anti-disengaging protective cover for use on hemodialyzers.
