BLOOD PICKER

A blood picker including one or more needles, a storage device, and a fluid transmission control system is provided. The needle is adapted to be inserted into a blood vessel of a human for blood detection. The storage device is in communication with the needle and provided with a drawing tube in communication with an inner space of the storage device. The fluid transmission control system includes a fluid transmission device, a driving controller, and a power supply. The fluid transmission device is in communication with one end of the drawing tube. The power supply provides a power source for the driving controller to enable the fluid transmission device, so that after the fluid transmission device is enabled, the inner space of the storage device is controlled by the fluid transmission device to generate a pressure difference, thereby allowing the blood to be drawn and stored in the storage device.

CAPILLARY BLOOD COLLECTION DEVICE

A device is used in combination with a fluid pressure source and a replaceable sampling tube having a pointed cannula section and a hollow for capillary blood collection. The device is provided with: a body defining a bore extending along an axis; a first flow path in fluid communication with the fluid pressure source; a rotor fitting in the bore and being capable of spinning in both directions about the axis; a boss section extending along the axis and so dimensioned as to rotatably support the sampling tube coaxially with the axis and expose the cannula section out of the boss section; and a detachable fastening binding the sampling tube to the rotor so as to set the sampling tube into rotation concentric with the axis and establish fluid communication between the first flow path and the hollow of the sampling tube.

Fluid control devices and methods of using the same

An apparatus for procuring bodily fluid samples with reduced contamination includes a housing having a sequestration chamber, an inlet, and an outlet. A flow controller defines a portion of the sequestration chamber and can transitionin response to a suction force exerted by a fluid collection device fluidically coupled to the outletfrom a first state in which the sequestration chamber has a first volume to a second state in which the sequestration chamber has a second volume greater than the first volume, to draw an initial volume of bodily fluid into the sequestration chamber. An actuator is coupled to the housing and is in fluid communication with the inlet and the sequestration chamber in a first configuration, and is transitioned to a second configuration to sequester the sequestration chamber from the inlet, and allow a subsequent volume of bodily fluid to flow from the inlet to the outlet.
