The present disclosure relates to a portable phototherapy device. More specifically, the present disclosure is directed to a portable phototherapy device capable of delivering natural.
A womb contains a lower oxygen environment than a surrounding environment. To adjust to this environment, a fetus will increase the oxygen carrying capacity through an increase in hemoglobin. When infants are born, the oxygen in their environment increases, and the excess hemoglobin is discarded and converted into bilirubin. When bilirubin is first created from heme in hemoglobin, it is considered unconjugated, as it is fat and not water soluble, and binds to albumin to be processed in a liver and excreted in urine and feces. Neurological tissue has a high affinity for unconjugated bilirubin and can cross the blood-brain barrier. Yet, newborn infants do not possess the ability to process bilirubin through their liver, so an excess of unconjugated bilirubin can build up in the babies' system.
Typically, an infant with a healthy diet of breast milk can process the bilirubin until the liver is developed enough to process the bilirubin on its own. However, 60% of all term newborns and 80% of premature newborns experience a build-up of bilirubin known as hyperbilirubinemia (jaundice) before the full function of the development of the liver. The use of phototherapy either through artificial or natural sunlight is a known effective treatment to reduce the amount of conjugated bilirubin in the infants' body. Phototherapy is effective because certain wavelengths of light can isomerize the unconjugated bilirubin into conjugated bilirubin (which is water-soluble) through the skin and help the infant pass it through their stool. If the levels of bilirubin in the bloodstream become too high, it can cross the blood-brain barrier and cause Kernicterus, a condition involving deposits of bilirubin in the brain. Kernicterus can cause illness or diseases, such as, cerebral palsy, developmental and intellectual delay, hearing deficiencies, dental dysplasia, and/or oculomotor disturbances.
In developing nations, jaundice caused by unconjugated hyperbilirubinemia is still a leading cause of infant mortality and complications. This can be attributed to a lack of electricity to power the phototherapy devices and the risks associated with natural sunlight therapy. While sunlight is readily available, placing newborn infants in sunlight for extended periods of time can risk exposure to skin-damaging UV rays and cause overheating. Additionally, effective natural sunlight phototherapy can be undermined by underexposure due to the fear of overexposure in unprotected sunlight. Ineffective or complete lack of phototherapy allows unconjugated hyperbilirubinemia to progress leading to complications such as kernicterus or even death.
Conventional phototherapy treatment of newborns with jaundice may involve placement of the infant in an isolette tank or incubator with direct use of high-powered lighting (e.g., LED lamps), as shown in
Other conventional phototherapy devices, as shown in
There remains a need to provide an effective phototherapy device for treating hyperbilirubinemia that is easy to transport around and inexpensive to manufacture. The phototherapy device should not require additional equipment(s), power source, maintenance or training to assemble and to operate, and must be particularly useful in areas of remote access, third world, and developing countries, where specific needs may be required.
In an exemplary embodiment, a phototherapy device capable of delivering natural sunlight to a subject is provided. The phototherapy device includes an incubator configured to hold a subject for treatment, a support for supporting the incubator, and an enclosure made from a flexible, transparent material connected to the incubator to create a space therein. The enclosure formed around the incubator allows visible sunlight to enter the enclosure in any direction for treating the subject while partially filtering ultraviolet (UV) and infrared radiation (IR) rays of the visible sunlight. The enclosure includes a first part made from a first material and a second part made from a second material different than the first material.
In another exemplary embodiment, a portable phototherapy device capable of delivering natural sunlight to a subject is provided. The portable phototherapy device includes a frame including an upper frame portion and a lower frame portion, and an enclosure including an upper enclosure portion and a lower enclosure portion. The upper frame portion and the lower frame portion include a plurality of rods. The plurality of rods are removable connected to each other. The upper enclosure portion and the lower enclosure portion are made from a flexible, transparent material to filter ultraviolent (UV) and infrared radiation (IR), and the upper enclosure portion can be separable from the lower enclosure portion. The upper frame portion can be framed as a structure to hold the upper enclosure portion and the lower enclosure portion. The lower frame portion can be framed as a structure to hold a bassinet.
In another exemplary embodiment, a portable phototherapy device capable of delivering natural sunlight is provided. The portable phototherapy device includes a frame including a first frame member and a second frame member, a support for holding a bassinet, and a flexible, transparent material attached to the first frame member and the second frame member to form an enclosure. The first frame member and the second frame member can be moveable with respect to each other causing the portable phototherapy device to be in a first configuration or in a second configuration. The support is positioned between the first frame member and the second frame member. The flexible, transparent material is configured to filter ultraviolet (UV) and infrared radiation (IR) rays of sunlight.
Other features and advantages of the present invention will be apparent from the following more detailed description of the preferred embodiment which illustrates, by way of example, the principles of the invention.
It should be noted that these Figures are intended to illustrate the general characteristics of methods, structure and/or materials utilized in certain example embodiments and to supplement the written description provided below. These drawings are not, however, to scale and may not precisely reflect the precise structural or performance characteristics of any given embodiment, and should not be interpreted as defining or limiting the range of values or properties encompassed by example embodiments. For example, the relative thicknesses and positioning of molecules, layers, regions and/or structural elements may be reduced or exaggerated for clarity. The use of similar or identical reference numbers in the various drawings is intended to indicate the presence of a similar or identical element or feature.
A phototherapy device, according to the present disclosure, is a device that is portable requiring no power source for use. The phototherapy device is lightweight, capable of being flattened, folded, rolled, compressed, or otherwise collapsed, to a size smaller than that of its operating size. The phototherapy device does not require special facilities for use; and allows for easy transport and shipment, as well as “in-home” or “field” application. The phototherapy device is not limited or constrained by any power source. The phototherapy device allows for directed and uninterrupted phototherapy without unduly confining or restricting the infant. While being portable, the phototherapy device is adaptable for fitted use over any pre-existing structure, framework, or device (e.g., infant incubator, crib, or bassinet). Unlike wraparound, or garment-type phototherapy devices, the phototherapy device does not come into physical contact with the infant, thus avoiding any physical distress, harm, or discomfort to the infant, and allowing for proper ventilation and circulation. The phototherapy device also allows caregiver access to the infant without having to operate or manipulate any elements on the device. This allows uninterrupted operation of the phototherapy device. The phototherapy device avoids undesirable conditions such as excessive heat and/or dehydration to the infant.
The phototherapy device is easy, and inexpensive to manufacture, to transport, and to ship. The phototherapy device requires no special facilities, equipment, power requirements, maintenance or training to assemble and to operate, thus making it particularly useful in areas of remote access, third world, and developing countries, where specific needs may be the greatest.
In an exemplary embodiment, a portable phototherapy device capable of delivering natural sunlight to a subject is provided. The portable phototherapy device includes a frame member having an upper frame portion and a lower frame portion and an enclosure having an upper enclosure portion and a lower enclosure portion. The lower frame portion is framed as a structure to hold a bassinet. The upper frame portion is framed as a structure to hold the upper enclosure portion and the lower enclosure portion. Further, the upper frame portion and the lower frame portion include a plurality of rods. The plurality of rods are flexible, semi-rigid to rigid enough to maintain a free-standing configuration. The plurality of rods can be removeable (i.e., disconnected) from each other. This allows for disassembly for easy transport or storage when not in use. Further, the upper enclosure portion can be designed to separate from the lower enclosure portion (i.e., removed with respect to the lower enclosure portion). This feature allows heat to be removed and/or allows a caregiver to handle the infant without disassembling the phototherapy device.
In another exemplary embodiment, the portable phototherapy device includes a frame including a first frame member and a second frame member. In this exemplary embodiment, the frame is capable of being flattened, folded, compressed, or otherwise collapsed, to a size that is less than the working space of the assembled and operational phototherapy device. The frame may be composed of poles, rods, tubes, slats, springs, or the like that can articulate, or can otherwise be positioned one to another such that they can be configured (e.g., “assembled”), with an enclosure, to form the structure of the phototherapy device. The frame can be configured (e.g., folded or disassembled) for easy transport or storage when not in use.
It should be appreciated that more than one window 50 may be employed to allow sunlight to reach the phototherapy device 1 in optimal application. This allows greater coverage that the sunlight has reached the phototherapy device 1. For example, the phototherapy device 1 can be next to a wall of a budding where the entire wall is made up of windows.
The incubator 10 can be provided (e.g., attached, mounted) on a base 20 that is supported on casters 25 (i.e., wheels). The use of wheels permits the phototherapy device 1 to be a movable base 20, and further allows the phototherapy apparatus 1 to be used with various incubators, cribs, and other infant supporting devices, including various therapy platforms. In other uses, the incubator 10, via the wheels, can be transported closer to the window 50 or in occasion, can be transported outdoor to receive the natural sunlight.
The enclosure 30 is attached to the incubator 10. That is, the enclosure 30 covers the incubator 10. In other words, the enclosure 30 forms a bubble creating a space between the incubator 10 and the enclosure 30 and permits the infant 5 to lie inside of the space. The enclosure 30 wraps entirely (e.g., formed 360° around the incubator 10. This allows sunlight to reach and enter the enclosure 30 in any or all directions for optimal light phototherapy. To describe in a different manner, due to the formed shaped of the enclosure 30, surface area of light exposure to the infant 5 is increased. In some implementations, a frame (not shown) may be coupled to an upper portion of the incubator 10 to form a structure such that the enclosure 30 encloses the frame and a portion of the incubator 10. The frame ensures the shape of the enclosure 30 attached to the incubator 10. In some implementations, the enclosure 30 may include fastening means to attach the enclosure 30 to the incubator 10. For example, the fastening means can be, but not limited to, zippers, buttons, hook-and-loop fasteners, adhesives, and/or tape. In some implementations, the fastening means can be provided on an outer surface of the incubator 10 such that the enclosure 30 is attached to the incubator 10. For example, there may be fastening means on all four sides of the incubator 10 to ensure a secure attachment.
The enclosure 30 can be made from many materials of various kinds of plastic or polyethylene sheet that is flexible and transparent. The flexible, transparent material filters ultraviolent (UV) and infrared radiation (IR) and constructed to prevent overexposure to the skin of the infant 5. Ordinarily, sunlight is broken down into three major components: (1) visible light, with wavelengths between 400 nanometers (nm) to 700 nanometers (nm), (2) ultraviolet light, with wavelengths shorter than 400 nm, and (3) infrared radiation, with wavelengths longer than 700 nm. To avoid the harmful components of sunlight, the enclosure 30 should receive only the visible light having the wavelengths between 400 nm to 700 nm to transmit the efficacy of monochromatic visible light to the infant 5. The optimal light wavelength range for jaundice treatment is in the blue light spectrum from about 380 nm to 470 nm. In that range, the orange to red bilirubin is able to absorb the maximum amount of light and break down the bilirubin into a form that the body can get rid of through urine and stool. The filtered enclosure 30 helps maintain the infant's unconjugated bilirubin levels from exceeding 20 mg/dL.
In some implementations, the flexible material of the filtered enclosure 30 has properties that is resistant to (enable to withstand) prevent cuts, tears, rips to the flexible material. For example, the flexible material of the filtered enclosure 30 can be made from, but not limited to, polyethylene, polypropylene, and/or polyvinyl chloride.
In some implementations, the flexible material of the filtered enclosure 30 has properties to prevent scratches on a surface of the flexible material, i.e., anti-scratching properties. For example, the anti-scratching properties can be embodied in the flexible material. In another example, the anti-scratching properties can be a coating or layer on an outer surface of the flexible material. The coating can be laminated or laminated together to form the flexible material.
In some implementations, the flexible material of the filtered enclosure 30 has properties to be deformable. That is, the flexible material is formed of a plastically deformable material that is flexible enough to be deformed to a desired configuration by hand while also having sufficient shape memory to retain the configuration to which it has been deformed during subsequent use of the device for delivery of a light therapy session.
The bassinet 15 includes a sheet to hold the infant 5 inside the incubator 10 or placed atop the sheet. The sheet is made from a material in which the material touching the skin of the infant is non-reactive and porous for air circulation, i.e., breathability. In some implementations, the sheet can be made from cloth, a mesh cloth or variation thereof. In one exemplary implementation, the sheet is a mesh pillow case-type doth. The mesh helps to allow air to pass to/from outside of the incubator 10 to the infant 5 (e.g., to expose the back of the infant). It should be appreciated that the cloth cover is not limited to mesh.
In some implementations, a pad 7 (e.g., a floatable mattress) is placed below the sheet to provide cushion to the infant 5, as shown in
In some implementations, the pad 7 includes a heating element (not shown) to heat the pad 7 before the infant 5 is placed in the incubator 10. The heated pad acts as a warming pad. The heating element can be a wired heating element that is disposed within the pad 7. In other implementations, the heating element can be placed below the pad 7. It should be appreciated the heating element must be connected to a power source and can only be available if plugged in.
In some implementations, the phototherapy device 1 includes a ventilation system 60 to vent or force air out of the incubator 10. That is, the ventilation system 60 helps remove air trapped in the enclosure 30 and eventually expelled out through the incubator 10. This prevents any overheating of the infant 5. For example, the ventilation system 60 ensures that the infant 5 does not exceed 100.4° F. In some implementations, the ventilation system 60 is located directly below the incubator 10. In some implementations, the ventilation system 60 can include ports to suction out the air inside the enclosure 30. The ports can be directly attached to the pad 7 to ensure sufficient expelled force is required to penetrate through the pad 7 and/or sheet.

The phototherapy device 2 includes a frame structure 40 having an upper frame portion 40a and a lower frame portion 40b and an enclosure 30 having an upper enclosure portion 30a and a lower enclosure portion 30b. The lower frame portion 40b is framed as a structure to hold the bassinet 15. In one implementation, the lower frame portion 40b is formed as a shape of a rectangle. The upper frame portion 40a is framed as a structure to hold (e.g., encompass, wrap) the upper enclosure portion 30a and the lower enclosure portion 30b. In one implementation, the upper frame portion 40a is formed as a shape of a pyramid. R should be appreciated that other shapes can be implemented as long as the upper frame portion 40a and the lower frame portion 40b are structured to hold the bassinet 15 and enclosure 30, respectively. Further, the frame structure 40 is not limited in its composition, size or shape, but has a structure to support the phototherapy device 2 in a “free-standing” configuration.
As similarly described in
In some implementations, the upper enclosure portion 30a and the lower enclosure portion 30b are made from the same material. In other implementations, the upper enclosure portion 30a and the lower enclosure portion 30b are made from different materials. For example, the upper enclosure portion 30a can be made from a material that can receive the natural sunlight and filter UV and IR while the lower enclosure portion 30b can be made with a material that filters out the entire (i.e., reflects) sunlight. In some implementations, the upper enclosure portion 30a and the lower enclosure portion 30b have properties to be deformable. That is, the flexible material is formed of a plastically deformable material that is flexible enough to be deformed to a desired configuration by hand while also having sufficient shape memory to retain the configuration to which it has been deformed during subsequent use of the device for delivery of a light therapy session.
In some implementations, the upper enclosure portion 30a can be designed to separate from the lower enclosure portion 30b. In other words, the upper enclosure portion 30a can be removed with respect to the lower enclosure portion 30b. This feature allows heat to be removed and/or allows a caregiver to handle the infant 5 without disassembling the phototherapy device 2. In other words, the removed upper enclosure portion 30a allows the caregiver to reach inside of phototherapy device 2 and handle the infant 5.
The upper frame portion 40a and the lower frame portion 40b comprise a plurality of flexible rods 42 to form the structures of the upper frame portion 40a and the lower frame portion 40b. The plurality of rods 42 should be flexible, semi-rigid to rigid enough to maintain a free-standing configuration. Additionally, the plurality of rods 42 should be sturdy enough to hold the weight of the infant 5. In some implementations, the plurality of rods 42 are hollow rods made from plastic materials that is deformable and easy to cut to suitable lengths for any particular shape or design. For example, the plurality of rods 42 are non-conductive, extruded fiberglass rods having ¼ inch or ⅜ inch diameter.
As shown in
In some implementations, as shown in
In some implementations, the plurality of rods 42 can be permanently connected to the connector 44. For example, adhesive, such as glue may be applied on an inner surface of the connector 44 to permanently connected the rods 42 to the connector 44. In other implementations, glue may be used to sufficiently hold the pieces (e.g., rods 42 and/or connector 44) together to provide a tight secure fit, rather than a permanent hold.
Similarly, the upper frame portion 40a can be formed using the plurality of rods 42 to form the structure of the upper frame portion 40a. Same pieces (e.g., rods 42 and/or connector 44) of the lower frame portion 40b can be used to form the upper frame portion 40a.
In some implementations, the upper frame portion 40a and the lower frame portion 40b can be formed in a unitary manner. In other words, the upper frame portion 40a and the lower frame portion 40b can be constructed as one-piece members.
The phototherapy device 2 can include a sensor 70. In some implementations, the sensor 70 can measure temperature inside of the phototherapy device 2. If a certain temperature is reached, an indication to alert the caregiver that the inside of the phototherapy device 2 is too warm is sent. In other implementations, the sensor 70 may send a signal to operate a ventilation unit (now shown) to either force air into the phototherapy device 2 or expel air out of the phototherapy device 2. In other implementations, the sensor 70 can measure humidity (or moisture) inside of the phototherapy device 2. Similarly, if a certain moisture is read, an alert to the caregiver is given and/or to operate the ventilation unit. In some implementations, the sensor 70 can measure vitals of the infant 5. For example, vitals include, but not limited to, temperature, blood pressure, heart rate, and respiratory rate. In some implementations, the sensor 70 can be a light measuring instrument. For example, the sensor 70 can measure an intensity of a radiation of the visible light via a filter configured to read transmission spectrum of the light. It should be appreciated that the sensor 70 can determine as one or a combination of the above mentioned operations.
In one implementation, the sensor 70 is located near the top of the phototherapy device 2. More specifically, the sensor 70 is located on top of the upper enclosure portion 30a. In other implementations, the sensor 70 can be located at other locations. For example, the sensor 70 can be located at any location in the lower enclosure portion 30b and/or on the bassinet 15.
The phototherapy device 3 includes a frame 53 and a bassinet holder 56. The frame 53 is designed to hold the bassinet holder 56 and the enclosure 30 (not shown). The frame 53 includes a first frame member 53a and a second frame member 53b. The frame 53 can be made from similar materials as the rods 42 described in
To maintain the portable feature of the phototherapy device 3, the frame 53 is capable of being flattened, folded, compressed, or otherwise collapsed, to a size that is less than the working space of the assembled and operational phototherapy device 3 (as shown in
In some implementations, the frame 53 may be composed of poles, rods, tubes, slats, springs, or the like that can articulate, or can otherwise be positioned one to another such that they can be configured to be “assembled” (
