An infusion device for bone marrow aspiration
PendingCN122075083AImprove stabilityprevent prolapseDiagnosticsSurgical needlesMechanical engineeringMedical device
This invention discloses an infusion device for bone marrow aspiration, belonging to the field of medical device technology. The invention includes a base, a counterweight, and an infusion assembly. The key features are: the base contains multiple pressure sensing mechanisms, a balancing and stabilizing mechanism, and a protective mechanism. The pressure sensing mechanism includes a pressure groove and a sensing piston, connected to a large air reservoir and a small air reservoir; the balancing and stabilizing mechanism includes a balancing groove, a moving slider, a telescopic spring, a stabilizing plate, and a lifting piston. The lifting piston is connected to the moving slider via a traction line, and the small air reservoir is connected to a limiting cavity via an air inlet pipe; the protective mechanism includes a fixed support, a rotating shaft, a protective cloth, and a reinforcing rope. The large air reservoir is connected to an adjusting cavity, and the adjusting piston is driven by the rotating shaft; the rotating shaft is also connected to a limiting assembly for controlling the extension length of the stabilizing plate. This invention achieves dynamic stabilization, intelligent protection, and coordinated adjustment through pneumatic linkage, effectively preventing needle displacement and ensuring infusion safety.
