  • Publication number: 20230256223
    Abstract: A method of preventing infections in vascular access devices in which an acoustic wave generator is attached to the vascular access catheter, and the acoustic wave generator is activated to produce acoustic waves, which are transmitted to the vascular access catheter to create mechanical vibrations in the vascular access catheter. The acoustic waves may be ultrasound waves. The acoustic wave generator may be attached to a catheter tube of the vascular access catheter or attached to a hub of the vascular access catheter. The acoustic wave generator a separate device that is removably clipped to the vascular access catheter, may be provided in a vascular access catheter stabilization device or may be integral with the vascular access catheter.

  • Publication number: 20230241369
    Abstract: A cap configured to engage different types of connectors includes a housing, an absorbent support, and a seal. The housing includes a sidewall extending between a first end and a second end of the housing. The absorbent support is positioned in the housing. The seal is mounted to a portion of the absorbent support and is configured to cover an opening of a first connector or a second connector when one of the first connector or the second connector is inserted into the housing. The cap is configured to be secured to the first connector by an engagement between a portion of an inner surface of the sidewall of the housing and the first connector and to the second connector by an interference engagement between another portion of the inner surface of the sidewall of the housing and an outer surface of the second connector.

  • Publication number: 20230113122
    Abstract: A method for predicting inventory availability, involving receiving a delivery order including a plurality of items and a delivery location, and identifying a warehouse for picking the plurality of items. The method retrieves a machine-learned model that predicts a probability that an item is available at the warehouse. The machine-learned model is trained, using machine learning, based in part on a plurality of datasets. The plurality of datasets include data describing items included in previous delivery orders, whether each item in each previous delivery order was picked, a warehouse associated with each previous delivery order, and a plurality of characteristics associated with each of the items. The method predicts the probability that one of the plurality of items in the delivery order is available at the warehouse, and generates an instruction to a picker based on the probability. An instruction is transmitted to a mobile device of the picker.

  • Publication number: 20220401654
    Abstract: A thermoplastic elastomer stopper that meets the desired material properties of a stopper for a syringe assembly is disclosed. The compression set of the thermoplastic elastomer stopper of the present disclosure is ?50% when measured at 25% compression for 22 hrs at 70 degree C. The hardness of the thermoplastic elastomer stopper of the present disclosure is 40-70 Shore A. The viscosity of a thermoplastic elastomer stopper of the present disclosure is ?70 Pa·s at 1,000 s?1 shear rate, ?12.0 Pa·s at 10,000 s?1 shear rate, and ?3.0 Pa·s at 50,000 s?1 shear rate when measured using a capillary rheometer at 205 degree C. (Die: Roundhole 20 mm length/1 mm diameter/180 degree inlet, Piston: d=15 mm, and melting time=7 min). The present non-lubricated stopper exhibits the required functional performance of a lubricated stopper.
