  • Patent number: 10940096
    Abstract: 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.

  • Patent number: 10292908
    Abstract: 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.

  • Patent number: 9931279
    Abstract: 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.

  • Publication number: 20170014310
    Abstract: An enteral feeding adapter system for use with a bottle cap having a dispensing opening, and an oral syringe having a male syringe element. The system includes a cap adapter having a male adapter element configured to be insertable into the dispensing opening to place the cap adapter in fluid communication with the bottle cap. The cap adapter further includes a male ENFit connector in fluid communication with the male adapter element. The enteral feeding adapter system further includes a syringe adapter having a female ENFit connector configured to be selectively engageable with the male ENFit connector to place the syringe adapter in fluid communication with the cap adapter. The syringe adapter further includes a female adapter element in fluid communication with the female ENFit connector and configured to receive the male syringe element to place the syringe adapter element in fluid communication with the oral syringe.

  • Patent number: 9474863
    Abstract: 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.

  • Publication number: 20160074575
    Abstract: A supplemental pain medication device may be placed in parallel with a basal rate controller for providing a temporary increased level of pain medication to a patient on demand. a trigger of the supplemental pain medication device must be initially depressed in order to allow fluid to flow through the device so that an upper body of the device which is attached to a plunger may slide into a lower body which is attached to a reservoir. When the upper body is slid into the lower body, the plunger also slides into the reservoir to pump fluidic pain medication out of the device.

  • Patent number: 9265699
    Abstract: 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.

  • Patent number: 9227022
    Abstract: 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.

  • Patent number: 8403004
    Abstract: 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.
