This is a continuation-in-part of U.S. application Ser. No. 08/501,815 filed on Jul. 13, 1995.
FIELD OF THE INVENTIONThis invention relates to an improved specimen container which is adapted to maintain the sterile integrity of the container and to prevent leakage yet which can be temporarily, partially opened and closed with one hand, leaving the other hand free to insert the specimen with a needle and syringe (N&S), cannula and syringe (C&S) or a syringe with no attachment without having to first put the instrument down.
BACKGROUND OF THE INVENTIONSpecimen containers are well known in the art and are available in a host of shapes and sizes. However, a user of specimen containers typically must use both hands to operate the container. The user must hold the receptacle in one hand and remove the cover with the other hand, while holding a syringe containing an aspirated specimen. The user must then squirt the specimen into the open receptacle, risking the possibility of splash back or spillage. Therefore, it has been identified that a specimen container which enables a user to grasp, open and close the lid with one hand, and with the user's other hand, to inject the aspirated specimen into the container without splash back or to withdraw a specimen from the container without spillage, would be beneficial to the user. Further, it is also recognized that a specimen container which facilitates insertion of a cannula or a syringe with no attachment into the specimen container by providing a cannula guide would also be beneficial.
SUMMARY OF THE INVENTIONIt is therefore a primary object of this invention to provide a specimen container which enables a user to grasp a specimen container with one hand and, with the user's other hand, to inject the aspirated specimen into the container without splash back or to withdraw a specimen from the container without spillage.
It is a further object of this invention to provide a specimen container having a plug cover which enables a user to grasp, open and close the plug cover with one hand, and with the user's other hand, to inject the aspirated specimen into the container without splash back or to withdraw a specimen from the container without spillage.
It is a further object of this invention to provide a specimen container which facilitates insertion of an instrument, such as a needle or cannula, into the specimen container by providing a guide for the tip of the instrument.
It is a further object of this invention to provide a lid, provided with one or more self-resealing portals therethrough, for any type of receptacle adapted to contain a solid and/or a liquid.
A preferred embodiment of the specimen container of this invention, adapted to maintain the sterile integrity of the container and to prevent leakage, comprises: a receptacle having an opening; a lid comprising a means to seal said opening and having a top surface and a bottom surface and a bore therethrough; and a plug comprising, an upper and lower shoulder, at least one of said shoulders is deformable, wherein said plug is seated in said bore of said lid so that said upper shoulder is seated on said top surface of said lid and said lower shoulder is seated on said bottom surface of said lid, and a membrane capable of being penetrated with a material transfer device and which self-reseals to prevent leakage from said container. Material transfer device generally refers to a variety of instruments used to transfer fluids or other similar materials from one point to another, including but not limited to cannulas, needles and syringes connected to a somewhat pointed attachment adapted to puncture a membrane.
The specimen container may further comprise a plug cover, preferably comprising high density polyethylene, which covers a top surface of the plug and which is adapted to be raised and lowered by a person's one hand leaving the person's other hand free to insert a specimen into, or withdraw a specimen from, the specimen container. The plug cover is preferably hingedly fixed to the lid and includes a flange which surrounds the upper shoulder of the plug when in a lowered position. The plug cover may further comprise a flange which is adapted to engage a corresponding flange on the lid when the plug cover is in a lowered position so that the plug cover is removably fixed in the lowered position to further prevent any material from entering or leaking out of the receptacle.
