A priming valve includes a fluid flow path, a fluid inlet configured to couple to a fluid outlet of a fluid channel including at least one sensor configured to characterize at least one attribute of a fluid, a fluid outlet, a valve seat, and a connector. The connector engages the valve seat to prevent fluid flow via the fluid flow path. The connector is configured to move relative to the valve seat in response to a threshold pressure within the fluid flow path to allow the fluid to flow via the fluid flow path. A flow sensor sub-assembly for sensing flow of a fluidic medicament may include a priming valve and at least one sensor of a fluid port configured to characterize at least one attribute of a fluid within an administrable fluid source. A method for readying a fluid sensor may use a priming valve.

A chest drainage system securing apparatus for securing and maintaining chest drainage systems in position following placement into a human or animal patient and preventing movement or unplanned removal thereof in response to the application of significant forces in any direction thereto, be they longitudinal, torsional/rotational or bending. The securement system includes retention devices secured to a chest tube which interact with an adhesive pad releasably attached to a patient to ensure proper positioning of the chest tube. The adhesive pad includes one or more Heimlich-type valves for sealing sucking chest wounds and for sealing an incision formed in a patients skin and chest for the placement and insertion of a chest tube.

Syringes are described herein. A syringe includes a syringe body, a first plunger, a second plunger, and an inner tube. The syringe body defines a syringe cavity and a syringe port, wherein the syringe port is in fluid communication with the syringe cavity. The first plunger is disposed within the syringe cavity and defining a first chamber in the syringe cavity, wherein the first chamber is in fluid communication with the syringe port. The second plunger is disposed within the syringe cavity, the first plunger and the second plunger cooperatively defining a second chamber in the syringe cavity. The inner tube comprises an inner tube lumen, wherein the inner tube and the first plunger shaft lumen define an annulus therebetween, the annulus in fluid communication with the first plunger channel and the annulus permits fluid communication between the syringe port and the first plunger channel.
