A syringe device includes a syringe barrel and piston having a fluid passageway extending from a vial port. Another syringe device includes a syringe barrel, a piston sleeve and an insert. A channel extends along a side of the insert. A valve controls fluid communication between the channel and the syringe barrel. Another syringe device has a syringe barrel, a piston sleeve and an insert. A valve controls fluid communication between a compartment within the insert and the syringe barrel. A method of preparing a medication includes providing a component within a syringe barrel and another component within a compartment of a piston insert. A seal is over-molded onto a tip of the insert and an end of a piston sleeve. The sleeve is rotated relative to the insert to establish fluid communication between the compartment and the barrel chamber.

An adaptor for retrofit attachment to a syringe has a slide slideably mounted on the barrel of the syringe, a housing for releasably engaging a flange formed on the trailing end of the syringe plunger, an elongate connector for interconnecting the slide and the plunger housing, and a guide that releasably engages a flange formed at the trailing end of the barrel. Movement of the slide effects simultaneous and corresponding movement of the plunger. This allows a syringe operator to perform aspiration and injection in sequence with one-handed operation of the syringe. The slide is adjacent the leading end of the plunger so that the operator can see the leading end of the plunger. The user's fingers support the syringe from below. The flange housing permanently engages the flange in a second embodiment. In a third embodiment, the elongate connector and plunger are formed integrally at their respective trailing ends.

A tamper evident assembly for retaining a plunger and piston within a barrel of a syringe including an elongated tether and a cover connected to the tether and concurrently disposed in an operative position on the syringe. A connector assembly adjustably and fixedly interconnects the tether to the cover in the operative position, wherein the cover is connected in covering relation to a discharge port of the syringe concurrently to a proximal end of the tether being connected to the syringe barrel in a removal preventative relation to the piston. Movable adjustment of the tether relative to the connector assembly defines a retaining segment disposed into a taut, fixed length orientation between the proximal end of the tether and the cover, to further define the operative position.

A medical syringe assembly includes a first opening and a second opening at opposite ends of a tubular barrel having an inner wall. The inner wall includes an inner surface. A stopper having an engagement surface is slidably received in the tubular barrel and includes a portion for engaging the surface of the inner wall of said tubular barrel. A lubricant is disposed over a limited area of at least one member of the inner wall of the tubular barrel and the engagement surface of said stopper, whereby a sufficient amount of the lubricant is available to provide adequate reduction of friction between the surface of the inner wall of the tubular barrel and the engagement surface of the stopper.

Disclosed is a syringe disposal device (10) suitable for disposal of a single syringe. The device is suitable for disposal of syringes (30) having a needle (33), a barrel (38), a plunger (39) and on the barrel (38) or plunger (39), a transversely extending flange portion (38a). The disposal device (10) may include a needle encapsulating portion (12), a syringe barrel encapsulating portion (14) and a syringe retention portion (16). The syringe retention portion (16) has an open end (18) to allow syringe (30) to be inserted into device (10). The opposed end (19) of syringe retention portion (16) communicates the retention portion (16) with syringe barrel encapsulating portion (14). Engagement means (20) are provided at, or proximate, the opposed end (19) of the syringe retention portion (16) for retaining syringe (30) within the disposed device (10) after passage of the transversely extending flange (38a) past the engagement means (20) by interference fit. The disposal device (10) is advantageously of tapered form.

The device comprises a first holding device (10) which is attached to a syringe barrel (11) of a syringe, and a second holding device (25) which is attached to a plunger barrel (21) of the syringe. Both holding devices are linearly guided relative to each other. One of the holding devices carries a dial gage (31) comprising a rotary shaft (30). Said rotary shaft (30) is in engagement with a toothing (29) of the other holding device. An indicator (32) indicates, with a high resolution, the movement of the plunger rod relative to the syringe barrel such that a highly accurate fine dosing of a liquid discharged from the syringe can be realized.

A device for monitoring a manually operated syringe that according to one embodiment includes a basis which is adapted to be connected to a medication administration point of a patient and comprises a syringe insertion port to receive the syringe dispensing tip, the basis being configured such that when the syringe is inserted in the insertion port the syringe barrel is not in direct contact with the basis, and at least part of the syringe barrel projects from the basis in the direction of the barrel axis, and further comprising an image acquisition system arranged on the basis and adapted to capture an image of at least part of the syringe plunger when the syringe is inserted in the insertion port.

An assembly for use with a syringe having a barrel and a needle includes a sealing element surrounding and positioned over at least a portion of the distal end of the syringe. An adapter at least partially surrounds the sealing element and is positioned over the distal end of the syringe. The adapter has a first skin contacting surface positioned at a distal end thereof. At least a portion of the first skin contacting surface extends generally parallel to at least a terminal end of the needle. The adapter also has a second skin contacting surface positioned proximally relative to the terminal end of the needle and at an angle to the first skin contacting surface. A needle shield at least partially surrounds and is removably positioned over at least one of the adapter, the sealing element and the syringe barrel.

The closure member has a thickness where a needle of a syringe can pierce the closure member to access the cavity of the body. A cannula (98, 118, 170) extends from the distal end of the body for accessing the container.

A disposable stripping type self-destruction syringe comprises a syringe barrel, a liquid outlet is fixed to the bottom of the syringe barrel, a core rod is inserted into the syringe barrel, the corerod is connected with a rubber plug structure, the core rod is detachably connected with the top end of the rubber plug structure, and conical lock catches are formed in the bottom end of the rubber plug structure in the circumferential direction, and the number of the conical lock catches is larger than or equal to 2. A hollow gap for separating the conical lock catches is formed in the middle ofthe bottom end of the rubber plug structure; an annular clamping protrusion matched with the conical lock catch is formed in the liquid outlet. The sum of the clamping force of the conical lock catchand the annular clamping protrusion is larger than the connecting force of the core rod and the rubber plug structure which is larger than the friction force between the rubber plug structure and theinjector barrel. When liquid medicine is injected, the rubber plug and the barrel are connected into a whole, and when the core rod is pulled back, the rubber plug structure is separated from the core rod, so that the injector is scrapped and cannot be used again, and the self-destruction function is achieved.
