Abstract

An apparatus for sealing prepared medications in enclosures includes a tubular sleeve having an open first end, an open second end, and an outer surface. The first end includes at least one first locking member for securely attaching the tubular sleeve to another member. The apparatus also includes a length of a flexible packaging sleeve that is open at one end and has an open interior space. The packaging sleeve is disposed about the outer surface of the tubular sleeve in a compressed form. The open end of the sleeve is sealingly attached to the first end of the tubular sleeve. A tensioner device is disposed about an outer surface of the packaging sleeve and includes a first section that couples the first end of the packaging sleeve to the tubular sleeve and at least two elongated tensioner arms that extend along a length of the tubular sleeve. The compressed packaging sleeve is disposed underneath the tensioner arms such that the tensioner arms apply tension to the packaging sleeve and control the unfurling thereof from the tubular sleeve. The open first end of the tubular sleeve is in communication with the open interior space of the packaging sleeve.

Claims

1. An apparatus for sealing prepared medications in enclosures comprising:

a frame defining a first sealed space;

a tubular sleeve having an open first end that is in selective communication with the first sealed space, an open second end, and an outer surface;

a tensioner device that is disposed about an outer surface of the tubular sleeve for applying tension to a member disposed thereunderneath and configured to receive the prepared medication;

a sleeve locking member that is coupled to the frame for releasably locking the tubular sleeve thereto the sleeve locking member when the first and second locking members engage one another, the sleeve locking member being constructed to permit the open first end of the tubular sleeve to be exposed to the sealed space; and

a cap that is releasably attached to the first end of the tubular sleeve for sealing the first end, wherein the cap is constructed such that it cannot be removed until the tubular sleeve and the sleeve locking member are in a locked position where the tubular sleeve is sealed relative to the first space.

2. The apparatus of claim 1, further including a robotic gripper that moves along a guide track, the robotic gripper including a pair of grippers that are actuatable and move between an open position in which the packaging sleeve can be received between the grippers and a closed position in which the packaging sleeve can be captured between the grippers and a prescribed liner movement of the robotic gripper causing a predetermined length of the packaging sleeve to be unfurled from the tubular sleeve.

3. The apparatus of claim 1, further including a controller that calculates a length of the packaging sleeve that has been removed and a length of the packaging sleeve that remains on the tubular sleeve.

4. The apparatus of claim 1, further including an automated heat sealer that includes a first part and a second part, wherein at least one of the first and second parts includes a heated element that forms a heat seal in the packaging sleeve resulting in the prepared medication being sealed in the packaging sleeve.

5. The apparatus of claim 3, further including an automated cutter that includes a blade for cutting the sealed packaging sleeve within and along the heat seal, wherein the first part serves as a back support surface onto which the packaging sleeve is compressed by both the second part that contains the heated element and the blade during a cutting action after the heat seal has been formed.

6. The apparatus of claim 1, wherein the packaging sleeve is constructed to be hung on a support without removing a protective outer wrap and is formed of a material that is non permeable to the medication.

7. The apparatus of claim 1, further including a controller which is configured to calculate a length of the packaging sleeve that has been unfurled and send an alert when only a prescribed length of packaging sleeve remains unfurled.

8. The apparatus of claim 1, further including a dose collection bin for receiving the enclosed medications and a controller that is configured to send an alert signal when a predetermined quantity of enclosed medications are contained in the dose collection bin.

9. The apparatus of claim 1, wherein the member disposed underneath the tensioner device comprises a length of a flexible packaging sleeve that is open at one end and has an open interior space, the packaging sleeve being disposed about the outer surface of the tubular sleeve in a compressed form, the open end of the sleeve being sealingly attached to the first end of the tubular sleeve, wherein the tensioner device applies tension to the packaging sleeve to control the unfurling thereof from the tubular sleeve.
