Embodiment Construction

[0025] Embodiments disclosed herein relate to ventilation adapter assemblies including filters, methods of making such ventilation adapter assemblies, methods of using such ventilation adapter assemblies, and urinary drainage bag systems including such ventilation adapter assemblies. A ventilation adapter assembly disclosed herein includes a filter configured to allow gas (eg, air) to flow therethrough while at least partially preventing fluid (eg, urine) retained in the ventilation adapter assembly from flowing therethrough. In an embodiment, the filter comprises a sintered porous PTFE filter, which may be in the form of a membrane ultrasonically welded directly to the polycarbonate component (eg, the non-porous polycarbonate component) of the vent adapter assembly.

[0026] While many of the embodiments disclosed herein discuss a ventilation adapter assembly in relation to a urinary drainage bag system (eg, a Foley catheterization system), it should be understood that the ven...

Abstract

Embodiments disclosed herein are directed to vent adaptor assemblies including a vent adaptor, methods of making such vent adaptor assemblies, method of using such vent adaptor assemblies, and urinarydrainage bag systems including such vent adaptor assemblies. In an embodiment, a vent adaptor assembly includes a filter that is configured to permit gas (e.g., air) to flow therethrough, while simultaneously at least partially preventing fluid present within the vent adaptor assembly (e.g., urine) from flowing therethrough.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Application No. 62 / 248,505, filed October 30, 2015, the entire disclosure of which is incorporated herein by reference. Background technique [0003] Typically, catheterization involves inserting a urinary catheter (eg, a tube) into the patient's urethra and into the patient's bladder. Conventional drainage systems for urinary catheterization include a urinary catheter (eg, a Foley catheter) connected to a drainage bag using a drainage tube. Thus, the urinary catheter allows the patient's urine to drain from the bladder through the drain and into the drainage bag. [0004] However, conventional drainage systems using urinary catheters can exhibit a number of fluid flow problems. For example, air locks, bends, or kinks at the drainage tube, which may restrict (eg, prevent) the flow of urine from the catheter into the drainage bag. Restricting the flow of urine may incr...
