Abstract

The present invention relates to an incubation system for liquid-based incubation of prematurely born infants, comprising: —an inner chamber forming an amniotic basin comprising amniotic fluid, said basin being configured for holding said infant and being made from a flexible material configured for expanding said inner chamber volume in correspondence with the growth of said infant; —an outer chamber enclosing said inner chamber and comprising a temperature regulation fluid, —a fetal connection port, arranged for connecting with the umbilical cord of said infant, said umbilical cord providing a port in said inner chamber to said infant for providing dialyzation and nutrition compounds to said infant via said umbilical cord; —a fetal control unit, connected to said fetal connection port for control of said dialyzation and control of said provided nutrition by monitoring and controlling one or more of a pressure, flow and temperature thereof; an amniotic fluid circulation unit, arranged for connecting with an inlet/outlet port of said inner chamber and comprising a pump for circulating said amniotic fluid from said inner chamber and through a purification system located outside said inner chamber; and —a temperature regulation fluid control unit, arranged for connecting with an inlet/outlet port of said outer chamber and comprising a pump for circulating said temperature regulation fluid from said outer chamber and through a heat exchanger system located outside said inner chamber.

Claims (29)

1. An incubation system for liquid-based incubation of prematurely born infants, comprising:

an inner chamber forming an amniotic basin containing amniotic fluid, the amniotic basin configured to hold an infant, and the amniotic basin made from a flexible material configured to expand an inner chamber volume in correspondence with growth of the infant;

an outer chamber enclosing the inner chamber, the outer chamber containing a temperature regulation fluid;

a fetal connection port configured to connect with an umbilical cord of the infant, the fetal connection port providing a port in the inner chamber to the infant to provide dialyzation and nutrition compounds to the infant via the umbilical cord;

a fetal control unit coupled to the fetal connection port to control the dialyzation and provided nutrition compounds by monitoring and controlling one or more of a pressure, flow and temperature thereof;

an amniotic fluid circulation unit configured to connect with an inlet/outlet port of the inner chamber, the amniotic fluid circulation unit comprising a pump configured to circulate the amniotic fluid from the inner chamber and through a purification system located outside of the inner chamber; and

a temperature regulation fluid control unit configured to connect with an inlet/outlet port of the outer chamber, the temperature regulation fluid control unit comprising a pump configured to circulate the temperature regulation fluid from the outer chamber and through a heat exchanger system located outside of the outer chamber.

2. The incubation system according to claim 1 , wherein the amniotic fluid circulation unit comprises a UV light source.

3. The incubation system according to claim 2 , wherein the amniotic fluid circulation unit comprises at least one sensor configured to purify the amniotic fluid.

4. The incubation system according to claim 1 , wherein the amniotic fluid circulation unit further comprises an inlet port configured to introduce nutrients and water into the amniotic fluid.

5. The incubation system according to claim 1 , further comprising at least one stimulation device disposed within or attached to the outer chamber.

6. The incubation system according to claim 5 , wherein the at least one stimulation device comprises at least one of an auditory stimulation device, a visual stimulation device, and a tactile stimulation device.

7. The incubation system according to claim 1 , further comprising at least one sensor disposed within or attached to the outer chamber.

8. The incubation system according to claim 7 , wherein the at least one sensor comprises at least one of a microfluidic device and a capacitive sensor.

9. The incubation system according to claim 7 , wherein the at least one sensor is selected from the group including a camera, an ultrasound imaging device, an electrocardiograph (ECG), an electroencephalograph (EEG), a tactile sensor device, a chemical analysis device for blood and/or amniotic fluid, and combinations thereof.

10. The incubation system according to claim 1 , further comprising an extra corporeal membrane oxygenation unit (ECMO).

11. The incubation system according to claim 1 , further comprising an inlet port assembly for fluids configured to connect with the umbilical cord of the infant.

12. An incubation system, comprising:

an inner chamber configured to hold an infant and expand in volume in correspondence with growth of the infant, the inner chamber containing amniotic fluid;

an outer chamber enclosing the inner chamber, the outer chamber containing temperature regulation fluid;

a fetal connection port received in the inner chamber and configured to connect with an umbilical cord, the fetal connection port configured to deliver dialyzation and nutrition compounds;

a fetal control unit coupled to the fetal connection port, the fetal control unit configured to monitor and control at least one of pressure, flow rate, and temperature of the dialyzation and nutrition compounds;

an amniotic fluid circulation unit coupled to an inlet/outlet port of the inner chamber, the amniotic fluid circulation unit including a pump configured to circulate the amniotic fluid from the inner chamber through a purification system located outside of the inner chamber; and

a temperature regulation fluid control unit coupled to an inlet/outlet port of the outer chamber, the temperature regulation fluid control unit including a pump configured to circulate the temperature regulation fluid from the outer chamber through a heat exchanger system located outside of the outer chamber.

13. The incubation system according to claim 12 , wherein the amniotic fluid circulation unit includes a UV light source and at least one sensor.

14. The incubation system according to claim 12 , wherein the amniotic fluid circulation unit is configured to supply at least one of nutrients and water to the amniotic fluid.

15. The incubation system according to claim 12 , further comprising at least one stimulation device disposed within or attached to the outer chamber.

16. The incubation system according to claim 12 , further comprising at least one sensor disposed within or attached to the outer chamber.

17. The incubation system according to claim 12 , wherein the fetal control unit includes an extra corporeal membrane oxygenation unit (ECMO).
