Fixing structure for filtering membrane in medical instrument

Abstract

The invention discloses a fixing structure for a filtering membrane in a medical instrument. The fixing structure comprises two fixing semi-rings, damping rings are clamped to the inner sides of the two fixing semi-rings, damping balls are movably connected to the front sides of the two damping rings, a filtering membrane body is clamped between the inner walls of the two damping rings, empty grooves are formed in the front sides of the two fixing semi-rings, fixing mechanisms are fixedly connected to the inner walls of the two empty grooves and clamped to the damping rings, and clamping mechanisms are fixedly connected to the reverse sides of the two fixing semi-rings. Through the damping rings and the damping balls, pressure borne by the inside and outside of each fixing semi-ring can berelieved, and thus use of the fixing semi-rings is more stable; through fixing plates and clamping plates, the damping rings can be better clamped and fixed, and thus use of the damping rings is moreconvenient; the filtering membrane body can bear external impact or pressure when bearing the large weight of an internal fluid medium, and shake and pressure borne by the filtering membrane body areeffectively reduced.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a fixing structure of a filter membrane in a medical device. Background technique [0002] Medical devices refer to instruments, equipment, utensils, in vitro diagnostic reagents and calibrators, materials, and other similar or related items that are directly or indirectly used on the human body, including the required computer software. The utility is mainly obtained through physical means, not through Obtained by means of pharmacology, immunology or metabolism, or although these methods are involved but only play an auxiliary role, the purpose is diagnosis, prevention, monitoring, treatment or alleviation of disease; diagnosis, monitoring, treatment, alleviation or functional compensation of injury; Examination, substitution, regulation or support of physiological structures or processes; support or maintenance of life; pregnancy control; providing information for medic...

AI Technical Summary

Problems solved by technology

[0003] The medical device industry involves many industries such as medicine, machinery, electronics, plastics, etc. Since the filter membrane in the medical device needs to transport the fluid medium for a long time, it needs to bear a large weight. When the filter membrane bears a large weight, the equipment in the When encountering external pressure or collision, it is very easy to damage, reduce the service life of the filter membrane, and easily cause the rupture of the filter membrane, so we propose a fixed structure of the filter membrane in medical equipment to solve the above problems
