Abstract

A holder for receiving a sampling tube of a blood sampling system is disclosed. The holder has an interior pocket which can be conformed from a closed position to an open position for receiving the sampling tube.

Claims

1-31. -31. (canceled)

32. A container for receiving a blood sample comprising:

a pair of oppositely facing walls defining an interior chamber;

an internal flow path extending substantially into said interior chamber, said internal flow path providing the only path for blood flow into and from said chamber.

33. The container of claim 32 wherein said interior chamber has a generally circular profile.

34. The container of claim 32 wherein said internal flow path is defined by a plastic tube.

35. The container of claim 32 wherein said interior chamber is defined by a pair of peripherally sealed oppositely facing walls.

36. The container of claim 34 wherein said plastic tube extends between said walls and is sealed at said peripheral seal.

37. A biological fluid sampling system comprising:

a plastic container defining an interior chamber;

an internal flow path extending substantially into said interior chamber, said internal flow path providing the only access into and from said chamber; and

a sample access site external to said container and communicating with said internal flow path.

38. The system of claim 37 wherein said access site is accessible by a vacuum tube holder.

39. The system of claim 38 wherein said access site includes a seal breakable by said vacuum tube holder.

40. The system of claim 37 wherein said internal flow path is defined by a plastic tube, one end of which is physically joined to said access site.

41. A blood processing set comprising:

a flow path for receiving blood from a donor, said flow path including a branch connector;

a flow path between said branch connector and a blood collection container;

a plastic sample container defining an interior chamber;

another flow path between said branch connector and said sample container;

a sample access site directly communicating with said other flow path; and

an internal flow path communicating with said access site and extending substantially into said interior chamber.

42. The set of claim 41 wherein said internal flow path provides the only access into and from said interior chamber.

43. The set of claim 41 wherein said access site is accessible by a vacuum tube holder.

44. The set of claim 43 wherein said access site includes a seal breakable by said vacuum tube holder.

45. The set of claim 41 wherein said internal flow path is defined by a plastic tube.

46. A blood processing set comprising:

a donor access device for drawing blood from a donor;

a flow path between said donor access device and a branch connector;

a flow path between said branch connector and a blood collection container;

another flow path between said branch connector and said sample container;

a sample access site directly communicating with said other flow path; and

an internal flow path communicating with said access site and extending substantially into said interior chamber.

47. The set of claim 46 wherein said internal flow path provides the only access into and from said interior chamber.

48. The set of claim 46 wherein said access site is accessible by a vacuum tube holder.

49. The set of claim 48 wherein said access site includes a seal breakable by said vacuum tube holder.

50. The set of claim 46 wherein said internal flow path is defined by a plastic tube.
