There is provided herein a system and a method for guiding insertion of a gastroenteral tube including: an electromagnetic field generator configured to generate an electromagnetic field covering a treatment area; wherein said electromagnetic field generator is external to the patient; a registration sensor configured to mark anatomic locations on the patient's torso; a gastroenteral tube comprising a tip sensor configured to sense its position and/or orientation relative to the electromagnetic field generator; and a processing circuitry configured to: calculate an orientation of the subject relative to the field generator based on the anatomic locations marked by the registration sensor, load a predefined anatomic map representing a torso; aligning the map based on the anatomic locations marked by the registration sensor, and showing on the map a path of the gastroenteral tube insertion; wherein the path is generated according to changes in the strength of the electromagnetic field sensed by the tip sensor's during the insertion of the gastroenteral tube, independent of the subject's movement and independent of deviations in the position and/or orientation of said field generator.

Methods and apparatus for guiding medical care based on sensor data from the gastrointestinal tract are described utilizing an apparatus which can be used with enteral feeding. Generally, the apparatus includes an elongated body having a length configured for insertion into a stomach and at least one pair of electrodes located along the length of the elongated body and positionable for placement within the stomach. A controller in electrical communication with the at least one pair of electrodes is included and the control may also be configured to measure a conductivity or impedance between the pair of electrodes and to determine a gastric residual volume of the stomach based on the measured conductivity or impedance.

An automatic breastfeeding method of a premature infant is disclosed, which includes a preparation stage, an active lactation stage, a passive lactation stage and a rest stage. The invention also provides an automatic breastfeeding machine used for the automatic breastfeeding method of a premature infant, comprising a stomach tube, a lactation supply device, a detector and a control device. According to the invention, a self-sucking ability of the premature infant is trained, normal circulation of a mouth-pharyngeal-gastric-intestinal reflex of the premature infant is realized, and nutritional requirements of the premature infant are ensured in the case of taking differences of the premature infants into account, so that the premature infants have no difference with term infants in care, diet, neurological development and growth and development in the future.

There is provided a method comprising: computing a target nutritional goal to reach at an end of a time interval based on a real time energy expenditure of a patient, wherein the target nutritional goal comprises a volume to be delivered (VTBD) by the end of the time interval corresponding to a target amount of energy expenditure of the patient over the time interval, computing a target feeding profile defining a target feeding rate for enteral feeding of the patient for reaching the VTBD by the end of the time interval, continuously monitoring the real time energy expenditure, adapting the target nutritional goal and corresponding VTBD to compute a maximum VTBD to reach at the end of the time interval according to the monitoring, and dynamically adapting the target feeding rate and the corresponding target feeding profile for a remaining portion of the time interval for reaching the maximum VTBD.

A computer-implemented method of adjusting enteral feeding of a patient by an enteral feeding controller, comprising: computing an estimate of energy expenditure of the patient based on oxygen measurements and carbon dioxide measurements of the patient, computing a target composition and target feeding rate for the enteral feeding according to the computed estimate of energy expenditure, when the target composition and target feeding rate differ from a current enteral feeding composition and feeding rate by a requirement, generating instructions for adjustment, by an enteral feeding controller, of the rate of delivery of the enteral feeding according to the target composition, wherein the receiving the oxygen measurement, receiving the carbon dioxide measurement, and computing the estimate of energy expenditure are performing iteratively for every first time interval, and the generating instructions for adjustment are performed for a second time interval that is larger than the first time interval.

A medical pump, comprising: a fluid housing having a plurality of intake openings, sealed by at least one intake valve, and an outlet opening sealed by an outlet valve; a piston which is sealing the fluid housing and connected to a drive mechanism, the drive mechanism pulls the piston to draw fluid from one of the plurality of intake openings and pushes the piston to discharge the fluid into the outlet opening; and a selecting valve enclosing at least two tubes, each providing fluid to one of the plurality of intake openings, wherein the selecting valve closes one of the at least two tubes while opening another of the at least two tubes.

There is provided a method comprising: computing a target nutritional goal to reach at an end of a time interval based on a real time energy expenditure of a patient, wherein the target nutritional goal comprises a volume to be delivered (VTBD) by the end of the time interval corresponding to a target amount of energy expenditure of the patient over the time interval, computing a target feeding profile defining a target feeding rate for enteral feeding of the patient for reaching the VTBD by the end of the time interval, continuously monitoring the real time energy expenditure, adapting the target nutritional goal and corresponding VTBD to compute a maximum VTBD to reach at the end of the time interval according to the monitoring, and dynamically adapting the target feeding rate and the corresponding target feeding profile for a remaining portion of the time interval for reaching the maximum VTBD.

The embodiments herein are directed to a portable liquid delivery system that incorporates an immersion driving pump mechanism(s), an administration reservoir, a user interface, and a wearable and/or portable accessory. The wearable accessory serves to house the components of the system and is to be worn on the user's body. In some cases, the system may be used to deliver nutritional formula for the treatment of patients on an enteral nutrition regimen.
