Blood collection device with tube retaining structure
First Claim
1. A blood collection device, comprising a body including a housing having a sidewall forming a receptacle sized and shaped to receive a blood collection tube, the body including a closed distal end having a needle extending proximally into the receptacle, an open proximal end opposite the closed end for receiving the collection tube as the tube enters the receptacle and a retaining arm extending proximally from a distal end connected to the sidewall of the housing at a location spaced from the closed distal end to a proximal end free from the housing, a portion of the retaining arm spaced proximally of the distal end of the retaining arm extending into the receptacle, a central portion of the retaining arm bowing inwardly from an inner surface of the housing into the receptacle, the central portion extending farther into the receptacle than the remainder of the retaining arm, the retaining arm being configured to retain the blood collection tube against proximal movement when the blood collection tube is received in the receptacle, wherein the central portion engages the blood collection tube to retain the blood collection tube when the blood collection tube is fully inserted into the receptacle.

Abstract
A blood collection device is disclosed which includes a body defining a receptacle dimensioned to receive a blood collection tube. The body has a first open end and a second end supporting a needle having a proximal end extending into the receptacle and a distal end extending distally of the body. Retaining structure is supported on the body. The retaining structure extends into the receptacle and is configured to releasably retain the blood collection tube within the receptacle.

- 1. A blood collection device, comprising a body including a housing having a sidewall forming a receptacle sized and shaped to receive a blood collection tube, the body including a closed distal end having a needle extending proximally into the receptacle, an open proximal end opposite the closed end for receiving the collection tube as the tube enters the receptacle and a retaining arm extending proximally from a distal end connected to the sidewall of the housing at a location spaced from the closed distal end to a proximal end free from the housing, a portion of the retaining arm spaced proximally of the distal end of the retaining arm extending into the receptacle, a central portion of the retaining arm bowing inwardly from an inner surface of the housing into the receptacle, the central portion extending farther into the receptacle than the remainder of the retaining arm, the retaining arm being configured to retain the blood collection tube against proximal movement when the blood collection tube is received in the receptacle, wherein the central portion engages the blood collection tube to retain the blood collection tube when the blood collection tube is fully inserted into the receptacle.
- 10. A blood collection device, comprising a body including a housing forming a receptacle sized and shaped to receive a blood collection tube, the body including a closed distal end having a needle extending proximally into the receptacle, an open proximal end opposite the closed end for receiving the collection tube as the tube enters the receptacle and a retaining arm extending into the receptacle from a distal end connected to the housing to a position inside the receptacle, the retaining arm having a distal portion, a proximal portion opposite the distal portion, and a central portion between the distal and proximal portions that is separate from an inner surface of the housing, the central portion of the retaining arm bowing inwardly from the inner surface of the housing into the receptacle, in which an inner engagement surface on the central portion of the arm selectively engages the blood collection tube when the blood collection tube is fully inserted into the receptacle, the inner engagement surface of the arm being adapted to provide increased frictional engagement of the blood collection tube compared to the distal and proximal portions of the arm, the inner engagement surface on the central portion extending farther into the receptacle than the remainder of the retaining arm.
- 16. A blood collection device, comprising a body forming a receptacle sized and shaped to receive a blood collection tube, the body having an end supporting a needle extending into the receptacle and an open end opposite the needle supporting end, and a retaining structure including a retaining arm pivotally supported on one end and a finger nub operably connected to the arm, the retaining arm being resiliently biased into the receptacle, such that the retaining arm is located within the receptacle in its natural unstressed configuration, and the finger nub being depressible to pivot the retaining arm outward from the receptacle to releasably retain the blood collection tube in the receptacle, the retaining arm being connected to the body at a distal end, a central portion of the retaining arm bowing inwardly from an inner surface of the body into the receptacle, the central portion extending farther into the receptacle than the remainder of the retaining arm, the retaining arm being configured to retain the blood collection tube against proximal movement when the blood collection tube is received in the receptacle, wherein the central portion of the retaining arm extending the farthest into the receptacle engages the blood collection tube to retain the blood collection tube when the blood collection tube is fully inserted into the receptacle.
