1. A device for collecting a blood sample, comprising:
- a collection unit comprising;
a top window;
a top surface;
a channel communicated with the top window;
at least one capillary tube having a top end adjacent to the top window;
wherein a distance between the top end of the at least one capillary tube and the top surface of the collection unit is in a range of 1.0 mm to 5.0 mm, such that the top end of the at least one capillary tube is used to contact with a blood drop from a puncture to continuously draw the blood flowing inside or along the at least one capillary tube into a storage unit by disrupting a surface tension of the blood drop, anda vacuum connector communicated with the channel, extended outwardly from the collection unit, and connected to a pressure control unit to remove air from the channel and create an alternating negative pressure in the channel; and
the storage unit disposed under the collection unit.

Abstract
A device for collecting a blood sample is provided. The device includes a collection unit, at least one capillary tube, a vacuum connector, and a storage unit. The collection unit has a top window for receiving the blood sample, a top surface, and a channel communicated with the top window. The at least one capillary tube is disposed in the collection unit and has a top end adjacent to the top window of the collection unit. The vacuum connector extends from the collection unit and communicates with the channel to provide a negative pressure by removing air in the channel. The storage unit is disposed under the collection unit for storing the blood sample.

22. A method of collecting a blood sample, comprising:
-
providing a collection unit having a top window, a top surface, and a channel communicated with the top window; providing at least one capillary tube in the collection unit having a top end adjacent to the top window for guiding a blood drop from the puncture to flow inside or along the at least one capillary tube, wherein a distance between the top end of the at least one capillary tube and the top surface of the collection unit is in a range of 1.0 mm to 5.0 mm, such that the top end of the at least one capillary tube is used to contact with a blood drop from a puncture to continuously draw the blood flowing inside or along the at least one capillary tube into a storage unit by disrupting a surface tension of the blood drop; removing air from the channel through a vacuum connector to create an alternating negative pressure in the channel by connecting the channel and a pressure control unit, wherein the vacuum connector is communicated with the channel and is extended outwardly from the collection unit; and storing the blood sample in the storage unit disposed underneath the collection unit. - View Dependent Claims (23, 24, 25, 26, 27)
