Abstract
An object is to provide a blood collection set configured such that a sampling holder and a needlestick-preventive needle cover are more difficult to disengage from each other than conventional. A blood collection set (500) includes a sampling holder (100) and a needlestick-preventive needle cover (200). The sampling holder (100) includes a tubular body (110), a lid (130), and a fitting portion (140) having a circumferential rib as a rib portion and a catching portion. The needlestick-preventive needle cover (200) includes an engaging portion (250) that is engageable with the catching portion of the sampling holder (100).
Core Innovation
The invention relates to a blood collection set comprising a sampling holder and a tubular needlestick-preventive needle cover. The sampling holder includes a tubular body having an opening portion and a lid configured to open and close the opening portion, and the fitting portion is provided on a surface of the lid on a side opposite to the tubular body. The tubular needlestick-preventive needle cover is configured to fit into the fitting portion, is opened at both ends, and accommodates a blood collection needle therein.
In the fitting portion, a rib portion protrudes from the surface of the lid on the side opposite to the tubular body. A catching portion comprises at least one protrusion provided on the rib portion, and an engaging portion of the tubular needlestick-preventive needle cover is configured to engage with the catching portion. The fitting portion further comprises at least one hole provided in a boundary portion between the rib portion and the surface of the lid, directly adjacent to each protrusion, with a plurality of protrusions and corresponding holes.
The engaging portion engages the catching portion such that a click is produced to generate stronger retention, with retention harder to disengage than conventional while enabling the cover to be fitted with a smaller force. The sampling holder further includes a hinge via which the lid is connected to the tubular body, and a central portion of the surface of the lid opposite to the tubular body is a flat planar surface configured to close the opening of the tubular body.
Claims Coverage
The partial independent-claim coverage includes two independent claims, directed to a blood collection set and a sampling holder. Across these claims, four inventive features are identified: the lid fitting portion with rib and catching protrusions, the needle cover engaging portion, boundary holes adjacent to the protrusions, and the hinge-connected lid with a flat planar surface.
Lid fitting portion with rib and catching protrusions
A rib portion protrudes from the surface of the lid on the side opposite to the tubular body, and a catching portion comprises at least one protrusion provided on the rib portion.
Needlestick-preventive needle cover with engaging portion
A tubular needlestick-preventive needle cover is opened at both ends, accommodates a blood collection needle therein, is configured to fit into the fitting portion, and has an engaging portion configured to engage with the catching portion.
Boundary holes adjacent to protrusions on the lid
The fitting portion further comprises at least one hole provided in a boundary portion between the rib portion and the surface of the lid, directly adjacent to each protrusion, with a plurality of protrusions and corresponding holes.
Hinge-connected lid closing the opening portion
A sampling holder comprises a tubular body having an opening portion and a lid configured to open and close the opening portion, with a hinge connecting the lid to the tubular body, and a central flat planar surface configured to close the opening of the tubular body.
Overall, the independent claims cover a blood collection set and sampling holder in which a tubular needlestick-preventive needle cover engages catching protrusions on a ribbed lid fitting portion with adjacent holes, and the lid is hinge-connected and configured to close the tubular opening.
Stated Advantages
Stronger retention that is harder to disengage than conventional.
Enables the tubular needlestick-preventive needle cover to be fitted with a smaller force.
Documented Applications
Application to other medical circuits is mentioned, including transfusion and hemodialysis.
