Embodiment Construction

[0037]A syringe is used herein to refer to a device having a drug compartment and a cannula for delivering the drug (eg, insulin) to a patient. Pen delivery devices typically contain multiple doses of medication and a single pen needle. The phrase "pen needle" refers to a needle carrying assembly that can be attached to the body of a medication pen such that the proximal end of the pen needle assembly enters the medication compartment and the distal end is adapted for insertion into an injection site to perform one or more injections. The terms "needle" and "cannula" are used interchangeably herein. In one embodiment, the cannula may be a member configured for insertion into an injection site of a subject. One example is a cannula with a beveled end for insertion into a patient. A "distal" direction as used herein is the direction towards the injection site, and a "proximal" direction is the opposite direction. "Axial" means along or parallel to the longitudinal axis of the...

Abstract

A syringe and needle hub for a syringe has distal patient-facing side having a surface for contact with the subject's skin during injection. The contact surface is formed by a distal face of a post supporting a cannula and an outer collar surrounding the post. The axial distance between the distal face of the post and the distal face of the collar provided a contact surface with a radius of curvature to control the desired injection. The syringe barrel can have finger flanges extending outwardly where the flanges have a tactile member such as a dimple projecting from a proximal face of the flange and recess in a distal face of the flange.

Description

technical field [0001] The present invention is in the field of injectable medical devices for delivering medicines or medicines to patients. In particular, the present invention relates to a syringe or pen needle having a needle bearing seat with a patient contact surface for improved injection performance. The patient contacting surface is configured to facilitate penetration of the cannula into the skin to a desired depth. The seat may be integral to the syringe barrel, or may be mounted on a medication pen for administering medication, but is not limited to use with such a device. Background technique [0002] Medication pens for the delivery of self-administered medication typically include a syringe or pen body, which houses a medication compartment, and a separate pen needle, which can be attached to and detached from the pen body. A syringe or pen needle comprises a needle bearing seat having a recess on the proximal side for receiving the pen body, and a proximal ...
