A syringe (200, 400) for use in a medication delivery device (100) comprises a vial. The vial (201, 411) comprises a chamber (206). The chamber is configured to receive a piston or plunger (205, 416). The syringe further comprises a needle attachment point (202), for the attachment of a hypodermic needle (204). The chamber is offset from the needle attachment point.

A method for using CO.sub.2 as a contrast material in medical imaging procedures is disclosed. The method includes providing a source of pressurized CO.sub.2. The step of providing includes connecting the source of pressurized CO2 to a compressed gas unit for controlling delivery of the CO.sub.2. The method also includes regulating pressure of the CO.sub.2 delivered by the compressed gas unit, transmitting the pressurized CO.sub.2 from the compressed gas unit to a control valve assembly for delivery to a patient in controlled dosages, and sequentially processing the CO.sub.2 with the control valve assembly and delivering the CO.sub.2 to the patient as a contrast media.

A hair growth applicator for promoting the growth of hair follicles by applying hair growth liquid, comprising a handle having an internal chamber for containing said hair growth liquid, said handle having a channel running from said chamber to a distal end of said handle, a tip disposed at said distal end of said handle with a plurality of needles disposed on said distal surface of said tip, said distal surface having an opening, wherein said chamber is in fluid connection with said opening on said distal surface of said tip

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.

The present disclosure relates to an activation system for a supplemental device that is attached to an existing design of a medicament delivery device, where the removal of a protective cap or other covering from the medicament delivery device pulls a blocking element from between electrical contacts to close a circuit between a battery module and a power source, thus activating the battery module. The supplemental device can further have a transmitter for communicating information about the use of the medicament delivery device to an external device, such as a smart device. Memory storage elements can also be included having unique identification data. The present disclosure also relates to a medicament delivery device having attached the supplemental device.

Apparatus and methods for delivering medicament to a patient. The apparatus may include elements with different capacities to attenuate or absorb sterilizing radiation. The apparatus may include a medicament delivery assembly with interactive elements for dose-setting, priming and medicament ejection. The assembly may include a chamber housing a radiation-sensitive medicament present in the apparatus during sterilization by electron beam. The assembly may include an actuator chassis, a drive mechanism, a needle-priming mechanism and a fluid-displacement mechanism including a fluid-displacement member. The chassis may be fixed, relative to an outlet, to the chamber. The member may be slidingly and/or threadingly engaged with the chassis, and may be configured to move relative to the outlet to deliver the medicament through the outlet. Assembly elements may be nested coaxially and/or stacked axially. The assembly may include at least one hollow region. The hollow region may reduce beam attenuation or reduce radiation absorption.
