ABSTRACT:
A self-filling blood collection device has a frusto-conical body through which a channel extends. The body is formed to have a lure end to mate with a needle and another end that is fitted with a hydrophilic filter that allows air to pass through but is self-sealing when exposed to fluid. The cavity volume of the channel is configured to accept different minute amounts of blood for testing. An insert may be fitted within the channel of the device to decrease the cavity volume so that a smaller amount of blood is collected. Once punctured with a needle attached to the lure end of the device, blood from the patient will self-fill the channel of the device due to the blood pressure of the patient. A vent cap may be added to the device to make it adaptable to be used with all types of blood analyzer equipment.
