Abstract
The carrier for prefilled syringes has a body made from a dimensionally stable elastic material with a chamber for inserting the syringe. The flange of the syringe cylinder is fixed in the axial direction in a defined recess, whereas the syringe plunger is fixed in any position in an elongated recess.
Core Innovation
A syringe transport carrier is described for a prefilled syringe, including a syringe cylinder with a flange and a plunger inside the cylinder and including a plunger rod. The carrier comprises a body made from a dimensionally stable elastic material and a chamber to receive the syringe. The chamber includes a recess that fixes the position of the flange of the received syringe cylinder in an axial direction of the received syringe.
The chamber further includes an elongated recess in which the plunger rod is pressed between walls of the elongated recess. In this configuration, the elongated recess fixes the position of the plunger rod of the received syringe in any position in the axial direction. The described design holds syringes with varying plunger positions without a defined axial stop, while axially fixing the plunger rod by pressing between opposing recess walls.
The transport carrier is described as accommodating a sealing plug via a coaxial indentation on the needle side, and optionally includes a removal opening. Additional recesses form a chamber for a cannula. Testing described in the content indicates the carrier reliably prevents axial plunger displacement due to air-transport pressure differences, thereby protecting sterility of the content during storage and transport.
Claims Coverage
The partial content provides one independent claim. The independent claim includes two main inventive features: a carrier body made from a dimensionally stable elastic material and a chamber that axially fixes both the syringe cylinder flange and the plunger rod position via specific recess geometries (including axial fixing in any axial position for the plunger rod).
Dimensionally stable elastic-material body
A carrier for a prefilled syringe includes a body made from a dimensionally stable elastic material.
Chamber axially fixing flange and plunger rod by recesses
The chamber to receive the syringe includes a recess fixing a position of the flange of the received syringe cylinder in an axial direction and an elongated recess pressing the plunger rod between walls such that the elongated recess fixes the position of the plunger rod of the received syringe in any position in the axial direction.
The independent claim covers a dimensionally stable elastic-material carrier body with a chamber that axially fixes the syringe cylinder flange and presses the plunger rod in an elongated recess to fix the plunger rod position in any axial position, thereby enabling reliable retention during transport.
Stated Advantages
Reliably prevents axial plunger displacement due to air-transport pressure differences.
Protects sterility of the content during storage and transport.
Documented Applications
Storage and transport of a prefilled syringe using the described syringe transport carrier, with protection of sterility of the syringe content.
