A system for purging air from a feeding line is set forth. The system includes a charging device configured to selectively provide an air charge in the system. A restricting tubing can be located between the charging device and a delivery tube. The restricting tubing can be configured to tunably limit the air charge delivered from the charging device to the feeding line through the delivery tube.

Enteral feeding air purge system and method

A neonatal enteral feeding system for delivering neonate fluid is disclosed. The system includes a cooling unit for cooling the breast milk before, during and after a feeding cycle to mitigate unwanted bacterial growth and reduction of fat content in the breast milk. The system also includes a warming unit for heating the cold breast milk to a temperature above room temperature (preferably, standard body temperature) so that the neonate can focus his or her energy on healing, growth and digestion instead of heat generation. Additionally, the system has a peristaltic pump which draws the breast milk from a bottom side of the container and the container is vented so as to be capable of delivering all of the breast milk in the container to the neonate.

Neonatal enteral feeding system

A heating system for heating neonate nutritional liquid, including a heater and a control module. The heater includes a heating portion having serpentine shaped grooves for receiving a tube. The tube may be a serpentine feeding tube module, having a serpentine tube portion, or a serpentine feeding tube cassette, having a serpentine tube portion covered by a rigidly attached polymeric sheet. The serpentine feeding tube cassette may include a thermocouple to measure the temperature of the warmed nutritional liquid as it exits the cassette.

Enteral feeding adapter

A multi-purpose syringe that may be used both for gravity feeding and syringe pump assisted feeding of a neonate is disclosed. The multi-purpose syringe includes a cap and a plunger. The cap and plunger may be selectively engaged to the barrel depending on whether the neonate is fed by gravity or syringe pump. The cap seals the top of the barrel but allows gas to pass between the inside of the barrel and the environment and traps liquid within the barrel. To this end, the cap has an aperture covered by a hydrophobic member.

Multi-purpose syringe

A gravity fed infant feeding device is disclosed. The gravity feeding device may have a cover with a through hole that allows liquid nutrients within the infant feeding device to be fed to an infant by way of gravity. If the infant feeding device clogs up, then either an integrated pump or a separate pump may be applied to the infant feeding device to increase pressure and push out the clog from the system. the through hole may be covered with a hydrophobic filter to allow air to pass there through and allow the feeding of the infant by way of gravity yet liquid nutrients within the infant feeding device cannot escape or be contaminated during use.

Gravity feeding device

A heating system for warming nutritional liquid fed to a neonate or preterm infant may comprise a control module and a heater. The heating system is portable so that the heating system is not connected to a syringe pump or other device used to feed the neonate. The heater of the heating system is mounted to the tube that is used to feed the neonate. The heater is positioned along the tube in close proximity to the neonate so that a temperature drop of the nutritional liquid after the nutritional liquid exits the heater and reaches the neonate is negligible. The heater raises the temperature of the nutritional liquid to a target desired temperature (e.g., body temperature of the mother and neonate or to a temperature above the temperature of the mother and neonate) so that the neonate may consume warm nutritional fluid. Once the nutritional liquid reaches the neonate, the nutritional liquid is at about the body temperature of the mother or neonate or at least above room temperature.

A variable flow rate controller is provided herein. The controller may have a linearly traversable switch such that the controller is primed to flush air bubbles out of the fluid system of the controller prior to administering fluidic medication to a patient. Moreover, the controller may have a plurality of valves which may be independently opened and closed by a caming surface. To close the valve, a first seal may be disposed between offset inlet and outlet to prevent fluid from flowing from the inlet to the outlet. To open the valve, the first seal is disposed on one side of both of the inlet and outlet. Fluid if permitted to flow from the inlet to the outlet.

A safety needle device is provided for protecting a user against needle-stick injuries. This needle device includes a needle housing having a distal housing opening. A needle is disposed within the needle housing and has a distal needle portion which extends away therefrom through the distal housing opening. An elongate sheath assembly surrounds the needle within the needle housing. A biasing member is engaged to the sheath assembly and is configured to apply a force thereupon towards the distal housing opening. The biasing member defines a centerline which is parallel to the needle's distal needle portion. An indexer is engaged to the biasing member and is operative to increase or decrease a spring force of the biasing member by rotating the indexer. A trigger member is engaged to the biasing member for retaining the sheath assembly within the needle housing against the force urging the sheath assembly towards the distal housing opening. The trigger member is sized and configured to release the biasing member. This allows the sheath assembly to transition towards and out of the distal housing opening via the force to thereby enclose the distal needle portion therewith.

Huber needle with anti-rebound safety mechanism

A safety needle device for protecting a user against a needle-stick injury. This needle device includes a needle housing having a distal housing opening. A needle is disposed within the needle housing and has a distal needle portion which extends away therefrom through the distal housing opening. An elongate sheath assembly surrounds the needle within the needle housing. A trigger member retains the sheath assembly within the needle housing against a force urging the sheath assembly towards the distal housing opening. The trigger member is sized and configured to release the sheath assembly from retention to allow the sheath assembly to transition towards and out of the distal housing opening via the force. This causes the sheath assembly to enclose the distal needle portion and protect the user against the needle stick injury.

A safety needle device for protecting a user against inadvertent needle-stick injury. This needle device includes a needle housing having a distal housing opening. An arcuate groove extends within the needle housing terminating adjacent the distal housing opening. A needle is disposed within the arcuate groove having a distal needle portion extending away from the needle housing through the distal housing opening. An elongate sheath assembly surrounds the needle within the groove. A biasing member is disposed within the needle housing and is configured to move the sheath assembly throughout the length of the arcuate groove and through the distal housing opening. The sheath assembly then completely enclose the distal needle portion.
