The present disclosure relates to immobilization systems, and more particularly customized immobilization systems for treatment of an injured area.
When bones are fractured, cracked, or ligaments are lengthened or ruptured, an orthopedic cast or splint is often applied to the injured area to immobilize the injured joints and muscles partially or entirely.
One issue with using splints or casts is that they can often not be easily applied to and removed from the injured area. For example, application of a plaster bandage can be complicated, and once the plaster bandage is placed over the injured area, it typically remains in place for about five weeks, which can promote the growth of mold or infectious bacteria. Further, the process of the removing cast by using a saw can generate dust, which can cause problems to the injured area.
Moreover, when the cast is applied around the injured area, it can be difficult to initiate early joint movement, and inaccurate or abnormal fixation cannot be checked through intermediate inspections due to the cast covering the injured area. Even after the splint or cast is removed, it can often be replaced with another type of splint, for the rehabilitation phase and can result in similar issues noted above. Since rehabilitation cannot be started until bone immobilization is completed, the application of a splint to the injured area can lead to muscular atrophy. Long recovery times can result in unnecessary costs to the injured person, since there are a number of the healthcare providers and other individuals (e.g., patients, employers, rehabilitation centers and health insurance companies) involved in the recovery process.
Thus, there is a need for an immobilization system that can overcome these and other issues.
In one aspect, a system for immobilization and treatment of an injured area is provided. The system comprises a splint for placement around an injured area, a therapeutic device coupled to the splint to effectuate treatment of target tissues, and a wireless interface configured to communicate with the therapeutic device to transmit treatment data to the device.
In some embodiments, the splint is sufficiently flexible to permit movement around the injured area. In some embodiments, the splint is perforated to promote air circulation, and to minimize microbial growth around the injured area. In some embodiments, the therapeutic device is designed to transmit progress data to the wireless interface. In some embodiments, the therapeutic device is an electrotherapeutic device. In some embodiments, the therapeutic device is a sensor to detect muscle mass index. In some embodiments, the wireless interface is configured to receive and store data received from the therapeutic device.
The system can, in some embodiments, transmit treatment data to the wireless interface from a remote location, prior to the wireless interface sending the treatment data to the therapeutic device. In some embodiments, the wireless interface can be designed to receive sensor data from the therapeutic device, which can be sent to a remote location for monitoring.
In another aspect, a method for orthopedic treatment is provided. The method comprises providing an immobilization system including a splint, designed from a three dimensional (3D) scan of a limb for placement around an injured area, and a therapeutic device coupled to the splint, which can be configured to effectuate treatment of target tissues around the injured area. The method further includes sending treatment data to the therapeutic device via a wireless interface to effectuate treatment, by action of the therapeutic device transmitting a stimulation signal to the target tissues.
In some embodiments, the stimulation signal is used to treat skeletal or muscle tissue. In some embodiments, the method allows the wireless interface to communicate with a health care provider's computer to inform the provider of treatment progress. In some embodiments, the method can also permit a provider to send additional treatment data to the wireless interface that can be transmitted to the therapeutic device for treatment.
In another aspect, a method for treatment of an injured area is provided. The method comprises identifying an injured region on a limb, placing markers on the limb around the injured region, and then scanning the injured region with markers to generate data. The data can be used to fabricate a splint that conforms to the features of the limb. The splint can be used to attach a therapeutic device and active the device wirelessly to treat the injured area.
The presently disclosed embodiments will be further explained with reference to the attached drawings. The drawings shown are not necessarily to scale, with emphasis instead generally being placed upon illustrating the principles of the presently disclosed embodiments.
While the above-identified drawings set forth presently disclosed embodiments, other embodiments are also contemplated, as noted in the discussion. This disclosure presents illustrative embodiments by way of representation and not limitation. Numerous other modifications and embodiments can be devised by those skilled in the art which fall within the scope and spirit of the principles of the presently disclosed embodiments.
The present disclosure is directed to an immobilization system designed to improve processes for treating an injured area. The immobilization system can improve patient quality of life by improving the patient's healing processes through the use of a custom splint. The custom splint, in one embodiment, can be generated through the use of a fabrications system as described below.
With reference to
For purposes of the present invention, the 3D scanner 110A can be configured to generate a substantially true image of a limb. 3D scanner 110A can be configured to interface with a computer to obtain, store, and process scanned image data. Scanned image data, in one embodiment, maybe processed using software that is capable of analyzing the data and identifying injured areas. It is contemplated that 3D scanner 110A can be scaled to allow for applications that require small dimensions, for example, mobile applications.
In some embodiments, the 3D scanner 110A can be configured to obtain color, infrared and depth information from the images collected from a scan. To that end, in one embodiment, the 3D scanner 110A can be configured with two cameras 119B. For example, a suitable camera for use with 3D scanner 110A can be the Intel RealSense SR300 camera. It is contemplated that additional configurations of cameras, infrared projectors or other imaging devices can be utilized to obtain scan data. Depending on the application, these devices can be fixedly positioned about ring 117 or can be designed to circumferentially move along ring 117. In this way, the 3D scanner 110A is capable of generating a substantially true image of a limb, and subsequently model a custom made splint based on the image data of the limb.
The 3D scanner 110A, in an embodiment, can be calibrated according to protocols using motion detection, or standards of known length to detect and correct discrepancies in data acquisition and printing. These calibration methods are well known in the art.
To facilitate the fabrication of a splint that can be customized to each individual patient, in accordance with an embodiment of the present invention, markers 120 can be placed on the limb around the injured area to help scanner 110A of the fabrication system 105 in detecting features or target areas located on the limb to which treatment, such as that provided by a therapeutic device (i.e., electrotherapeutic device) needs to focus. The markers 120, according to embodiments of the present invention, can be of different shapes, colors, and/or patterns. The markers 120, according to embodiments of the present invention, can be used to identify a site of an injury, or demarcate the desired borders for the to-be-fabricated splint. Markers 120 can also be used to provide perforation patterns or openings in the splint to allow circulation of air to the injured area to facilitate healing. Markers 120 can also be used to identify areas within the splint where thickness needs to be increased or decreased, or where the shape of the splint needs to be altered to increase or decrease pressure applied to the injured area. Markers 120 can further be used to identify where on the splint a therapeutic device, such as an electrotherapeutic device (discussed below), can be placed for treatment. Furthermore, the use of markers 120 can help, for example, to create a structural offset, spacing, or gaps between the limb and splint. The structural offset can enable the splint to, for example, reduce pressure to a target area of the limb or, accommodate a foam insert to reduce irritation, chafing, or discomfort.
The markers 120, in one embodiment, can be applied to the limb before scanning by scanner 110A. With the markers 120 in position on the limb, control screen 116 can be accessed to initiate a 3D scan by scanner 110A. As the limb is scanned, the position of the markers 120 can be captured along with the limb data as digital 3D scan data. As the digital 3D scan occurs, scanner 110A also receives information corresponding to the color spectrum, infrared profile, and depth profile of the scan, which can then be included in the 3D digital scan data file. The digital 3D scan data, including data from the markers 120, can then be transferred to a computing device and processed to construct a 3D model of a to-be-fabricated splint that conforms to the features on the limb or areas of interest identified by marker 120 where the to-be-fabricated splint needs to target.
It should be appreciated that the 3D scanned data can be processed through software of the present invention to represent a 3D model of a to-be-fabricated splint on a three dimensional coordinate system. Such a rendering of a 3D representation using the process of the present invention, can allow the user to select and manipulate the properties of specific regions on the splint prior to fabrication. The processed 3D scan data can, in one embodiment, be used in connection with various fabrication methods, for example, traditional 3D printing processes, or in connection with any fabricating devices coupled to computer interfaces.
Once the limb has been scanned, looking now at
Placement of the photo-polymeric material 32 over the injured body part can be accomplished, in one embodiment, as illustrated in
With the photo-polymeric material 32 placed over the injured body part, pressure can then be gently applied against the injured body part to conform the photo-polymeric material 32 to the limb. To the extent desired, another scan of the injured limb maybe executed in order to verify any variation in the injured limb's position, to ensure accuracy of the 3D scanner data to be used in fabrication.
Next, looking now at
In an embodiment, the area of the photo-polymeric material 32 onto which UV light is projected is cured, for example in about 30 seconds or more, to form a shape of splint 40. In one embodiment, the uncured portions of the sheet of photo-polymeric material 32, can thereafter be removed to provide the customized splint 40, as shown in
It should be appreciated that customized splint 40 may need to have different properties, as will be described below, to accommodate different limb shape, profile, and/or injuries suffered by different patients. To that end, in some embodiments, the photo-polymeric material 32, can be provided with different properties, for example, throughout sheet 32, along the length of sheet 32, along the thickness of sheet 32, in each layer of sheet 32 (if sheet 32 is made from multiple layers), or a combination thereof, so that once the photo-polymeric material 32 is cured, the desired property or properties can be imparted to the resulting customized splint 40.
The customized splint 40, thereafter, can be removed from the limb for cleaning. It should be appreciated that by using two sheets of photo-polymeric material 32 placed above and below the limb, once splint 40 is formed, there is provided an upper half 41 and a bottom half 42 that can be naturally separated along an area where the two photo-polymeric sheets 33 initially adjoin, as illustrated in
As an alternative to the use of one or more sheets or photo-polymeric material 32 to fabricate customized splint 40, data obtained from the 3D scan can be utilized to fabricate the customized splint 40 by a 3D printing process. In one embodiment, instead of projecting the image of splint 40 onto the limb, as noted above, a 3D printing process may be utilized to spray or deposit (i.e., print), layer by layer, the material to form splint 40 following the desired shape and pattern, such as the pattern shown in
Of course, should it be desired, splint 40 may not need to be printed directly on the limb of the patient. Rather, splint 40 may first be printed and thereafter be placed onto the limb around the injured area.
It should be appreciated that various 3D printing protocols can be utilized in connection with the fabrication of customized splint 40 of the present invention. Examples of 3D printing protocols include 3D printing via Stereolithography (SLA), Digital Light Processing (DLP), Fused deposition modeling (FDM), Selective Laser Sintering (SLS), Selective laser melting (SLM), or Electronic Beam Melting (EBM).
The fabricated customized splint 40 may thereafter be used in an immobilization system 100 (see

Referring now to FIG.8A and
The spaces 45, in some embodiments, may provide for placement of one or more therapeutic devices, such as stimulator 50, directly against skin, while proving structure for securing the stimulators in place. As shown in
Splint 40 can also be provided with multiple regions where the shape, thickness or size is varied to apply or relieve pressure at or around the injury site to facilitate the healing process and provide comfort to the patient. For example, in some embodiments, the shape of the splint 40 can be designed to conform or avoid contours or feature of the limb. In other embodiments, the thickness of the splint 40 can be increased to apply more pressure to the limb, or the thickness of the splint 40 can be decreased to reduce the pressure to the limb.
Splint 40, in various embodiments, may be custom manufactured using 3D technology to match the shape and size of the injured body part. In one embodiment, data obtained, for example, from a 3D scan of a limb or region of the body, can be used to model and to create a custom-fitting splint 40. In particular, the 3D scanned data can be digitally processed to create a digital representation of the limb or body region. Subsequently, in one embodiment, the splint 40 may be fabricated using a process of the present invention. In particular, the 3D scanned data may be utilized to generate a map of the customized splint 40. The map of customized splint 40 can then be projected onto a photo-curable polymer, where the polymer reacts to the projection of light, to cure the polymer in the shape of splint 40. The uncured portions are then removed and used to provide the desired customized splint 40.

In some embodiments, the therapeutic device 50 can be configured to allow control of the intensity, frequency, and duration of the stimulation. By varying the output of therapeutic device 50, user defined settings can be utilized to tailor fit treatment as needed.
As illustrated in
Many patients experience atrophy of immobilized muscles over a period of time. By measuring the muscle mass index, atrophy can be monitored to guide treatment plans, and to determine the level of stimulation provided, thereby minimizing or completely preventing muscle atrophy. In an embodiment, therapeutic device 50, may also be configured as a sensor, for example, to measure the muscle mass index of the injured area. Monitoring the muscle mass index of a patient can be accomplished by sending progress data from therapeutic device 50 to wireless interface 60A. The level of stimulation delivered by therapeutic device 50 can be modulated, for instance by a clinician or patient, to meet the need of the treatment plan. Of course if desired, therapeutic device 50 can be provided with other sensor capabilities, or alternative sensor devices can be used.
In various embodiments, therapeutic device 50 can be attached to splint 40 in any suitable manner. For example, in some embodiments, a thread, clip, screw fasteners, rivets, and/or snap-fits may be used to attach therapeutic device to splint 40. In other embodiments, therapeutic device 50 can be attached to splint 40 by adhesives, bonding materials, or by being magnetically fastened.

According to aspects of the present invention, the therapeutic device 50, in one embodiment, can receive signals from wireless interface 60A to deliver treatment programs to the injured area. In an embodiment, therapeutic device 50 can deliver stimulation from about 0 mA to a maximum 99 mA, with a normal operation range of 50-60 mA. Therapeutic device 50, in an embodiment, can deliver modulated waves in middle frequencies between about 1,000 Hz and about 500,000 Hz. The therapeutic device 50 may also be capable of mixing two currents (e.g., about 2000, 2500, or 4000 Hz). The therapeutic device 50 can transmit a wave form such that the current passes across 0 mA value once each period of the wave.
Exemplary user defined settings can include, low frequency stimulation, high frequency stimulation for isolated and/ or tetanic contraction. The frequency of stimulation delivered by therapeutic device 50 can include low frequency stimulation (e.g., less than 10 Hz) for isolated contractions. For example, a low frequency program can include periods of low frequency stimulation at about 2 Hz to about 10 Hz, each for about 30 seconds to about 10 minutes. The frequency of stimulation delivered by therapeutic device 50 can include high frequency stimulation (e.g., from about 25 Hz to about 100 Hz) for tetanic contractions. For example, a high frequency program can include periods of high frequency stimulation at 30 Hz and 50 Hz, each for about 30 seconds to 10 minutes. The frequency of stimulation delivered by therapeutic device 50 can include frequency stimulation from about 10 Hz to about 25 Hz for isolated and tetanic contractions. For example, a frequency program can include periods of low and high frequency stimulation from about 10 Hz and 25 Hz, each for about 30 seconds to 10 minutes. Therapeutic device 50 can deliver symmetric biphasic squared waves, for example, using frequencies of about 20 Hz to about 30 Hz, or about 30 Hz to about 50 Hz, or about 80 Hz to about 90 Hz.
Exemplary user defined stimulation treatment protocols can range from about 10 to about 15 minutes and can include periods of about 2 Hz to about 10 Hz (isolated contractions), about 10 Hz to about 25 Hz (isolated and tetanic contractions), and/or about 25 Hz to about 50 Hz (tetanic contractions). The treatment protocols can be activated by patients or by health care professionals. Electrotherapeutic device 50 can measure a user's muscle mass index before, during or after a treatment protocol. Stimulation therapy can be applied to two antagonistic muscles concurrently with one stimulation.
Another exemplary user defined treatment protocol can include two 3-10 minute sessions in the morning and evening. The average treatment time of a session can be about 5 minutes, consisting of an average treatment frequency of about 15 Hz and an average current of about 50 mA. The average time of agonistic cycle of about 200 milliseconds, followed by an antagonistic cycle of about 200 milliseconds, with an average rest cycle of 200 milliseconds between cycles. Therapeutic device 50 can measure a user's muscle mass during the rest cycle. Thermal contrast baths can be integrated into stimulation protocols to augment patient treatment. For example, the use of hot and cold baths to immerse the treated region can be utilized twice in the morning and twice in the evening, for about 1 minute in alternating hot and cold baths for up to about 6 minutes with a rest period of 30 minutes or more between thermal contrast baths.
According to aspects of the present invention, the immobilization system 100 can be operated as illustrated in
Treatment applications can be directed at health care providers with specific regulatory requirements. The immobilization system 100 can be compatible with the Health Level-7 or HL7 standard. HL7 refers to a set of international standards for transfer of clinical and administrative data between software applications used by various healthcare providers.
System 100 of the present invention confers many advantages over typical orthopedic treatments. For example, typical orthopedic treatments are designed to treat broken bones and muscle injuries in two linear steps. First, there is an immobilization step using a cast or a splint. Such step takes an average of 5 weeks. The second step after splint removal is a rehabilitation phase with physical therapy and suitable exercises that in average last 5 additional weeks. The total average process is 10 weeks long (
At least some aspects of the splint 40 can be digitally customized to fit the dimensions and imperfections of the patient's limb. It can be quickly positioned, lightweight and durable compared to the traditional casts, i.e. plaster casts and the like. Further, the splint 40 is perforated to promote air circulation, and to minimize microbial growth around the injured area. The customized splint 40 prevents muscle problems associated with traditional systems immobilization, such as the heavy weight of traditional materials. Further, the immobilization system 100 can provide stimulation can reduce pain and enhances the bone fusion process. Therefore, the customized splint saves ongoing visits to the rehabilitation center, and laborious processes for testing or consultation that instead are being performed remotely with continuous doctor supervision.
The present disclosure is directed to an immobilization system designed to improve processes for treating an injured area. Immobilization system 100 can improve patient quality of life by improving the patient's healing processes, as to eliminate unnecessary visits to hospitals or clinics, as well as saving time and money to all parties involved in the course of rehabilitation. Embodiments of immobilization system 100 of the present disclosure can be used in different industries and technologies including, the health industry, medical device technologies, space technologies, aquatic technologies, robotic system technologies and the like. Immobilization system 100 of the present disclosure can be used in creating stencils or insoles, armature or custom body protections. It is possible for the new immobilization system 100 of the present disclosure can be used in custom technology applications for to devices, such as for creating rapid protective cases, i.e. iPhone case, or a car cover replacement, a helmet or a glove.
