  • Patent number: 10827963
    Abstract: An apparatus useful for the rapid collection of blood from a subject (e.g., a blood vessel, such as the vein, artery or capillary bed of a bovine subject) and dispensing the blood therefrom into a test or collection device. In general, the apparatus comprises: (a) a body having a chamber formed therein, said chamber having an inlet and outlet, with said chamber configured to draw blood therein; (b) a hollow barrel connected to said chamber outlet; (c) an ejector operatively associated with said barrel; (d) a hollow needle connected to said body, with said hollow needle in fluid communication with said chamber through said inlet, so that blood can be rapidly drawn into said chamber through said needle. The needle is optionally removed and blood dispensed from the body into a test or collection device by actuating the ejector.

  • Publication number: 20180220945
    Abstract: An apparatus useful for the rapid collection of blood from a subject (e.g., the vein of a bovine subject) and dispensing the blood therefrom into a collection device includes: (a) a capillary body having a capillary chamber formed therein, with the chamber having an inlet and outlet, and with said chamber configured to draw blood therein through the inlet by capillary action; (b) a hollow barrel connected to the chamber outlet; (c) a plunger positioned in the barrel; and (d) a hollow needle connected to the capillary body, with the hollow needle in fluid communication with the capillary chamber through the capillary inlet, so that blood can be rapidly drawn into the capillary chamber through the needle by the combined action of vein pressure (or other pressure, if present, such as arterial pressure) and capillary action.
