Safe urinary catheter and manufacturing method
A urinary catheter may include a catheter shaft and a connector coupled with the proximal end of the catheter shaft. The connector may have a first arm ending in a fluid outlet configured to allow urine to flow out of the urinary catheter and a second arm with an aperture and ending in an inflation inlet used for introducing inflation fluid into the urinary catheter. The catheter may further include a primary lumen, an inflation lumen, a retention balloon mounted to the catheter shaft proximal to a fluid inlet and over a distal filling hole, and a pilot balloon mounted on the second arm of the connector over the aperture. The pilot balloon inflates at an inflation pressure that is higher than the inflation pressure of the retention balloon and lower than a predetermined pressure threshold.

Infusion pump
An infusion pump is disclosed. The infusion pump comprises a chamber having a distal end and a proximal end, and a longitudinal axis between the proximal end and the distal end. A piston is arranged for reciprocating movement within the chamber and along the longitudinal axis. At least one outlet is arranged from the chamber and may comprise an outlet valve. At least one inlet is provided into the chamber. The outlet and the inlet are axially spaced apart along the longitudinal axis of the chamber. A method for operating the pump is also provided.
PRESSURE-REGULATING CONNECTOR FOR INFUSION
A system for controlled delivery of a medical fluid may include an elastomeric pump, a valve member fluidly coupled to the elastomeric pump at one side and a catheter at an opposite side for delivering the medical fluid to a patient, and tubing fluidly coupling the elastomeric pump and the valve member. The elastomeric pump may include an elastomeric membrane and a shell surrounding the elastomeric membrane. The pressure of the medical fluid may be greater than a pressure of the vein to keep the vein open. The valve member may be movable between an initial closed position, a fully open position where the medical fluid is delivered to the vein of the patient at a predetermined fluid flow rate, and at least one intermediate open flow position where the medical fluid is delivered to the vein of the patient at a flow rate below the predetermined fluid flow rate.
Breast pump containers and methods
Systems and methods for pumping milk from a breast, wherein the milk is expressed from the breast under suction and milk is expulsed from the pumping mechanism to a collection container assembly.
Nasal rinsing cap for bottles
A nasal rinsing cap suitable for standard water bottle is disclosed. The body portion of the device can be attached to the top of the bottle. It has a cylindrical void matching the threaded portion of the bottle and a one-way fluid valve attached to another void extending from the cylindrical void and through the body portion. The body portion also includes a one-way air valve allowing the entry of air into the bottle. A top portion is removably or openably attached to the body portion. It has a tubular opening starting near the body portion and extending through the top portion. The top portion is configured so that it has a tip to be contacted with the user's nasal cavities. The top portion also has a pressure zone for closing the fluid valve by applying a pressure on it.

Valves and hubs for tubular devices and methods for making and using them
A valve is provided for a sheath, catheter, or other tubular device that includes a first face, a second face opposite the first face and an axis extending between the first and second faces. A first slit extends substantially parallel to the axis from the first face towards the second face to a first intermediate location within the valve body, a second slit extends substantially parallel to the axis from the second face towards the first face to a second intermediate location within the valve body, and a bore extends along the axis between the first intermediate location and the second intermediate location.
PURGE VALVE ASSEMBLIES SYSTEMS AND METHODS
Aspects include systems having an intravenous fluid bag, a tubing line assembly including tubing connected to a connector and a purge valve assembly including a spike and an outer housing. The outer housing is connected to the spike and includes a receiving end portion configured to receive the connector. The purge valve assembly further has a check valve provided within the outer housing. Generally, the purge valve assembly interconnects the fluid bag to the fluid tubing assembly for removal of air from the fluid bag prior to connection to the tubing line assembly. Various methods and purge valve assemblies provide a rapid infusion system for use. The purge valve assemblies do not require the user to reinsert the connector or spike into the intravenous fluid bag, creating a sterile solution to preparing the intravenous fluid for rapid infusion while reducing the risk of air emboli.
