  • Publication number: 20160220160
    Abstract: A specimen transfer device adapted to receive a blood sample is disclosed. The specimen transfer device includes a housing and an actuation member. A deformable material is disposed within the housing and is deformable from an initial position in which the material is adapted to hold the sample to a deformed position in which at least a portion of the sample is released from the material. A viscoelastic member is disposed within the housing between the material and the housing and between the material and the actuation member. The viscoelastic member is engaged with the actuation member and the material such that movement of the actuation member from a first position to a second position deforms the material from the initial position to the deformed position.

  • Publication number: 20160089070
    Abstract: A regulator for in-line modulation of the flow rate of fluid during blood collection includes a fluid transfer device for transferring fluid from a patient to a collection device. The fluid transfer device comprises a fluid passageway defined by a tubular sidewall and a flexible member associated with a portion of the tubular sidewall. The flexible member is configured for movement with respect to the fluid passageway upon exposure of the fluid transfer device to a differential pressure during a blood collection procedure to prevent collapse of a patients blood vessel. The flexible member of the regulator can be a frame surrounding a flexible diaphragm. Alternatively, the flexible member can include a flexible material integrally formed within the tubular sidewall of the pressure regulator.

  • Publication number: 20160081606
    Abstract: A regulator for modulation of the flow rate of blood out of a patients blood vessel during blood collection is disclosed. The regulator includes a housing having a housing inlet, a housing outlet, and a wall defining a housing interior. At least a portion of the wall includes a flexible member. A valve is associated with the flexible member and is in communication with the housing interior. The regulator is designed so that upon an application of a differential pressure within the housing interior, the flexible member and/or valve automatically move with respect to either the housing inlet or housing outlet to modulate a flow of blood moving through the housing. A manual over-ride device can be provided to enable a user to over-ride the automatic regulation and manually regulate the flow of blood through the housing.
