Syringe for dispensing medical foam having a substantially cylindrical barrel with a nozzle at its forward end and a plunger with a substantially cylindrical shaft disposed within the barrel. A flexible annular flange is provided on the inner surface of the barrel which extends toward the nozzle to contact the shaft and form a seal between the barrel and the plunger.

Apparatus and method for syringe support are disclosed. The syringe-support apparatus may include a front arm and a back arm connected at a hinge mechanism. The front and back arms may comprise a finger grip and thumb grip. A user may employ a well-known scissor-like movement in view of the finger grip and thumb grip, combined with the hinge mechanism. The front and back arms may further comprise a syringe securing mechanism, which may correlate hand motion with a syringe plunger motion. In view of the finger grip, thumb grip, and syringe securing mechanism, respectively, a user may engage the user's forearm muscles during aspiration and injection. The securing mechanism may comprise an adjustable barrel support and barrel support hook to secure a syringe barrel.

An ocular medical injector is provided for drug delivery. A method includes inserting a puncture member of the medical injector into the eye until the puncture member reaches the SCS. The puncture member defines a lumen therethrough. With the puncture member disposed within the SCS, a flexible cannula is advanced distally through the lumen of the puncture member, beyond the distal end portion of the puncture member and along the SCS towards a posterior region of the eye. The flexible cannula has an atraumatic distal tip and defines a lumen therethrough. With the distal tip of the flexible cannula disposed within the SCS beyond a distal end portion of the puncture member, a therapeutic substance is administered to the SCS.

Methods and apparatuses are disclosed for applying negative pressure to a wound site. In some embodiments, the apparatus comprises a source of negative pressure, a processing element, and a memory comprising instructions configured to, when executed on the processing element, cause the apparatus to attempt to generate, via the source of negative pressure, a desired negative pressure at the wound site. If the desired negative pressure has not been generated after a first predetermined period of time, the instructions cause the apparatus to: deactivate the source of negative pressure for a second predetermined period of time, and subsequently attempt to generate the desired negative pressure at the wound site.

An injection device may include a container, a mobile component, a spring, a sensor, and/or a wireless communication device. The container may have an open proximal end, a substantially closed distal end, and a reservoir including a medicament defined between the open proximal end and the substantially closed distal end. The mobile component may be provided in the container and be movable with respect to the container to cause the medicament to be expelled from the container. The spring may be connected to the mobile component and configured to cause the mobile component to move within the container. The sensor may be connected to an end of the spring and configured to measure a parameter associated with an injection operation of the injection device. The wireless communication device may be configured to communicate, to a computing device, information associated with the injection operation of the injection device.

A medical device and kit for visually displaying an injection pressure of a fluid, The device has a fluid path for the fluid and includes a piezochromic material which, under the action of a pressure of < 100 bar, displays a piezochromic color change that is perceptible to the human eye.

A drug delivery device includes a housing, a container disposed in the housing, a drive mechanism, a needle assembly, a fluid flow path, and a vortex flow adapter. The container contains a medicament which is urged out of the container by the drive mechanism. The needle assembly has a needle and/or a cannula to deliver the medicament from the container. The fluid flow path fluidically connects the container and the needle assembly. The vortex flow adapter is disposed within or defines at least a portion of the fluid flow path, and is adapted to urge the medicament to flow in a vortex pattern.
