Device to prevent apnea episodes in infants
Device ( 1 ) for preventing apnea episodes in infants, which simulates a breathing pattern suitable for synchronizing the infant's breathing and which is provided as a tactile direct stimulus, arranged in contact with the infant's back while sleeping; it comprises a breathing pattern generator means ( 2 ) that emits air pulses that reach the infant through transmitter means comprising a flexible conduit ( 3 ) that transports the air to an inflatable/deflatable chamber ( 4 ).
1. A device for preventing apnea episodes in infants that, while being used with a respective infant, simulates a breathing pattern suitable for synchronizing the infant's breathing and that is provided as a tactile direct stimulus arranged in contact with the infant's back while sleeping, comprising:
a means for generating the breathing pattern, which comprises a means for inflation and a means for deflation, that supply and extract air periodically, emitting air pulses that reach the infant by a means of stimuli transmitter comprising an inflatable/deflatable chamber which is configured to attach to the infant's body;
an adaptive means that surrounds the infant's torso in a manner as to hold the inflatable/deflatable chamber in contact with the infant's back,
wherein the means for inflation is an air pump, and the means for deflation is a pneumatic control valve, wherein the means for generating the breathing pattern is user programmable and generates air pulses according to a specific repetitive regime simulating different breathing rates for each respective infant, based on a normal breathing pattern for the respective infant,
wherein the simulated breathing pattern synchronizes the respective infant's breathing by providing the tactile direct stimulus to the respective infant via the adaptive means, thereby preventing apnea episodes in the respective infant;
wherein the means for generating the breathing pattern comprises a microcontroller that commands the operation of the means for inflation and the means for deflation to provide the specific repetitive regime simulating different simulated breathing frequencies, and wherein the microcontroller is associated with a safety device with pressure sensors that prevents over-inflation of the chamber or air supply interruption; and
wherein the means for generating the breathing pattern also comprises a case which houses the means for inflation and the means for deflation, and wherein the case is made of noise insulating walls.
2. The device according to claim 1 , wherein the means of inflation is a mechanical or electromagnetic device.
3. The device according to claim 1 , wherein the microcontroller is associated with an audible or visual warning device for cases of a malfunction of the device.
4. The device according to claim 1 , wherein the means for generating the breathing pattern also comprises a group of backup batteries ensuring the operation of the device in case of interruption of a power supply energizing the device.
5. The device according to claim 1 , wherein the case is formed by a rigid body having an upper wall, a lower wall and perimeter walls forming an inner cavity, wherein the case comprises at least one connection nozzle for air outlet/inlet, and the case comprises at least one interface panel for programming by a user.
6. The device according to claim 5 , wherein the case comprises means for positioning in the infant's environment allowing the case to be fixed to a support or arranged on a surface.
7. The device according to claim 1 , wherein the means for generating the breathing pattern comprises the inflatable/deflatable chamber that is configured to be attached to the infant and a flexible conduit that conveys air from a pump to the chamber.
8. The device according to claim 7 , wherein the inflatable/deflatable chamber is formed by two waterproof sheets, an upper sheet and a lower sheet joined at their perimeter edge which retain an unjoined area where a coupling nozzle is arranged, and wherein the upper sheet is flexible, and the lower sheet is either flexible or rigid.
9. The device according to claim 8 , wherein the upper sheet is made of elastomeric material.
10. The device according to claim 8 , wherein the flexible conduit is a hose extending from the connection nozzle to the coupling nozzle of the inflatable chamber.
11. The device according to claim 1 , wherein the adaptive means to the body comprises a flexible chamber container of the inflatable chamber with means for positioning on an article of clothing and means for arranging a flexible conduit.
12. The device according to claim 11 , wherein the flexible chamber container is a pocket formed by at least one top cover with a side opening for passage of the flexible conduit to the outside, and wherein the pocket is integrated in a wearable garment on a torso of the infant.
13. The device according to claim 12 , wherein the pocket is attached on the outside or inside of a piece of garment, in a back area of the garment.
14. The device according to claim 11 , wherein a piece of garment has openings for the passage of the arms of the infant and a side opening for the passage of the flexible conduit to the outside of said piece of garment.
15. The device according to claim 14 , wherein the piece of garment is a girdle adjustable at the perimeter of a torso of the infant.
16. The device according to claim 11 , wherein the flexible chamber container is a pocket formed by two parallel, flexible and soft covers, that are incompletely joined at their perimeter leaving an access opening for introducing the inflatable chamber, and comprising removable means for adhesion on one of its covers allowing to fix the flexible chamber to a piece of garment, and wherein the removable means for adhesion of the pocket comprise a contact adhesive patch disposed on the outer surface of one of the covers of the pocket.
17. The device according to claim 1 , wherein the device is arranged for hospital use, wherein the means for generating the breathing pattern has a pump of capacity sufficient to supply at least three devices at a time, which may be arranged in a larger case in close proximity to a plurality of units housing a plurality of infants that include the respective infant, and provide each unit with a respective means of inflating a respective chamber for each unit, wherein each unit also has a respective piece of garment that receives the respective chamber which is attached to the pump by a respective flexible conduit.
18. The device according to claim 1 , wherein the device is arranged as a single unit for individual at home use.
