This application is a continuation-in-part of U.S. application Ser. No. 10/353,873, filed Jan. 29, 2003, which is incorporated herein by reference.
The present invention relates, in general, to the field of patient identification devices. More specifically, the present invention is directed to a small, stand-alone patient identification device with diagnostic systems.
As a result of advances in health care, hospitals and other care providers now have the ability to continually monitor a patient's physiology and overall condition. Currently, such facilities use EKGs, pulse oximeters, and other devices to continually monitor an individual's conditions. These sensory systems are invaluable in monitoring an individual's condition and administering the proper care. However, existing sensory systems exhibit several deficiencies.
More specifically, existing sensory systems are bulky and require considerable resources. For example, existing sensory systems such as capnometers, pulse oximeters, heart rate monitors, and other devices are large and typically contain several parts and wires. Consequently, they must be intentionally removed to gain access to the patient or to transport him or her. Additionally, it is well known that sensory devices such as heart rate sensor wires, oxygen monitors, etc. are inadvertently unhooked when a person shifts in his or her bed or seat. Finally, patients or family members frequently disconnect the sensory equipment because the patient is uncomfortable.
In addition, existing sensory devices display and/or print individual reports which must either be recorded at the time they are issued or retrieved and incorporated into an individual's records for subsequent retrieval. Moreover, some devices actually print or issue their reports at a remote location which must be later transported and added to an appropriate individual's chart. Unfortunately, test results or charts are occasionally assigned to a patient other than the patient whose data is on the chart or test results. This problem is especially exacerbated where multiple patients are housed together in the same room or during emergencies; situations where care must be especially taken to avoid patient misidentification. The same concerns are equally prevalent under non-emergency conditions. Moreover, one patient's charts can be inadvertently placed in another patient's room. As a result, individuals may be misdiagnosed or given incorrect treatment. In fact, there have even been incidents where surgeries are performed on the wrong patients.
Finally, patients, doctors, nurses or others remove current identification bands for several reasons. For example, patients cut or tear off the bands when they feel uncomfortable. As a result, doctors and nurses cannot identify the patient and are unable to associate the patient with his/her chart. In addition, doctors and hospital workers also cut the ID bands merely for their own convenience during insertion of intravenous or intra-arterial catheters or during surgery. Furthermore, doctors routinely remove the ID bands prior to procedures involving extremities or when blood flow to an extremity is compromised by swelling related to inflammation, burn or edema. When the procedure is completed they are inadvertently not reattached or cannot be reattached. Consequently, workers must rely on memory or educated guesses to recall a patient's identity and correctly associate the patient with his or her chart/history.
The present invention discloses a system which solves or at least substantially reduces the impact of these problems associated with existing sensory mechanisms and identification systems.
Specifically, there is a need for an integrated diagnostic and identification system which monitors physiological activities, stores the results, and correctly identifies a patient. The diagnostic and identification device of the present invention incorporates extremity sensors to measure physiologic vital signs such as, for example, blood pressure, temperature, heart rate, tonometry, blood oxygen saturation, and/or pO2. The present invention provides a single comprehensive physiology monitoring device without using patch sensors and transducers.
Consequently, the integrated sensory and identification system of the present invention assesses a patient's physiologic status. In fact, the present invention advantageously provides one small device which performs various sensory functions. Therefore, the present invention is easily transported, can continually accompany the patient, and requires fewer resources such as energy than existing sensory mechanisms. Additionally, the present invention cannot be easily removed and thus provides more reliable and timely results.
Significantly, the present invention may also store test results for subsequent retrieval. This helps a care provider or other individual with the ability to view current or past physiologic conditions. More importantly, it helps reduce incidents of incorrect association of results with incorrect individuals. In turn, the present invention improves quality of care by inhibiting problems with mishandling and loss of test results.
Finally, the present invention helps health care providers as well as other individuals retain more accurate diagnostic records. The diagnostic and identification system of the present invention may be equipped to directly transmit patient identification and diagnostic information to a patient record management system, physician digital assistant, tablet PC, or any other device.
In accordance with the invention therefore:
It is one object and advantage of the present invention to provide an integrated diagnostic and identification mechanism.
It is another object and advantage of the present invention to provide an integrated diagnostic and identification system which is difficult to remove.
It is still further object and advantage of yet another exemplary embodiment of the present invention to provide an integrated sensory and identification system which associates physiologic measurements with a specific patient.
It is yet another object and advantage of the present invention to provide an integrated diagnostic and identification system with a locking mechanism which may only be unlocked using a separate key.
It is an object and advantage of one exemplary embodiment of the present invention to automatically unlock the diagnostic and identification system based on extremity sensors.
It is further an object and advantage of another exemplary embodiment of the present invention to store patient information.
It is an additional object of yet another embodiment of the invention to provide a diagnostic and identification system which communicates with a patient record management system or other device.
The above and other objects, advantages and features of the present invention will become more readily appreciated and understood from a consideration of the following detailed description of preferred exemplary embodiments of the present invention when taken together with the accompanying drawings of the present invention.
In accordance with the foregoing objects, the present invention comprises a diagnostic and identification bracelet that not only monitors an individual's physiology but is also difficult to remove. Advantageously, the present invention provides a single, small, low-cost diagnostic and identification system which is capable of assessing several physiological parameters. In the preferred exemplary embodiment, the diagnostic and identification bracelet is comprised of a material which is resistive to cutting and tearing. Significantly, this resistance to removal prevents any inadvertent or intentional disconnection of diagnostic equipment.
The bracelet of the present invention further comprises a plurality of physiologic sensors such as, for example, heart rate sensor, pulse oximeter, capnometer, and other sensory mechanisms. Since all the sensors are integrated in a relatively small bracelet, an individual's physiologic functions are regularly monitored even when the individual must be transported or during procedures. Additionally, the sensors require fewer resources than existing systems.
In the preferred exemplary embodiment, the acquired data from each diagnostic tool is combined into one consolidated output on the diagnostic bracelet. The results may be accessed via a portable display device or other monitor device connected to the output on the bracelet. In another exemplary embodiment, the diagnostic bracelet further comprises memory to store acquired physiologic measurements. This allows a health care provider or other individuals to access physiologic measurements at regular intervals or when desired.
In other exemplary embodiments of the present invention, the diagnostic bracelet comprises a lock which may only be selectively unlocked using a key. Additionally, in yet another exemplary embodiment, the bracelet automatically unlocks itself based on the profusion of the extremities to which it is attached. Finally, the diagnostic bracelet may further comprise wired or wireless communication technology to access and/or store patient identification as well as physiologic information.
The following figures are schematic representations of the invention:
FIG. 1—is a top plan view illustrating the identification bracelet with a viewing device connected to an output;
FIG. 2—is a side elevational view illustrating the identification bracelet including various sensory systems; and
FIG. 3—illustrates a detailed patient information management system in which exemplary embodiments of the invention are implemented.
While various embodiments of the present invention are discussed in detail below, it should be appreciated that the present invention provides inventive concepts that can be embodied in a wide variety of specific contexts. The specific embodiments discussed are merely illustrative of specific ways to make and use the invention, and do not limit the scope of the invention.
Turning first to
The diagnostic and identification bracelet 10 further comprises an identification mechanism 11 such as a name tag or a bar code. The identification mechanism 11 allows an individual to simply read or ready identify the individual wearing the bracelet 10. Additionally, it will be appreciated that the identification information may further include an embedded microprocessor or microcomputer 19 as shown in
The preferred exemplary embodiment of the diagnostic and identification bracelet 10 additionally comprises a lock 12 which may be any commonly found lock. For example, a micro-lock may be used. The lock inhibits bracelet removal by securely fastening the bracelet 10 and permits removal only by doctors or workers who posses a key. Moreover, the lock can be re-locked so the bracelet 10 can be removed and re-secured.
Additionally, the diagnostic and identification bracelet 10 comprises a device for tracking the disengagement duration 100 which tracks the duration that the bracelet is disengaged or removed from the user. In the preferred exemplary embodiment, the device for tracking disengagement duration may simply be a timer on the bracelet which is initiated when the bracelet is disengaged. It should be appreciated that any device which is able to track the disengagement duration, preferably unauthorized removal of the bracelet 10 may be used as the device for tracking the disengagement duration 100. The device for tracking disengagement duration 100 may be independent device or may communicate with the microprocessor 19.
As seen in
However, it is possible that the diagnostic and identification bracelet may comprise sensors which use small or unobtrusive sensory patches to monitor physiologic conditions. For example, the diagnostic and identification bracelet may comprise small sensors 13 mounted on the outside of the bracelet. Nonetheless, these small external sensors may still be connected to the microprocessor to provide their output.
In the preferred exemplary embodiment, the bracelet 10 comprises a single activation mechanism connected to the aforementioned microprocessor 19. The microprocessor 19 in turn communicates with each physiologic sensor over a bus. However, it should be appreciated that the microprocessor 19 and the physiologic sensors 13 may communicate via a wired or wireless means. For example, short range and long range wireless protocols or known wired communication methods such as over a bus may be utilized. The output of each individual sensor is combined by methods well known in the art to provide a single output 15 to which a viewing device 16 may be connected.
The single output 15 may comprise a serial, universal serial bus, or other such interface. Alternatively, the single output 15 may comprise short range wireless transmission technologies such as, for example bluetooth technology or longer distance wireless communication technologies such as, for example, 803.11 or cellular technologies Moreover, the single output 15 may comprise a removeable memory media port such as, for example, a secure digital or memory stick port. In addition, the viewing device 16 may comprise any commercially available display device, but preferably a portable display device. This may comprise, for example, a personal digital assistant, smart phone, or any other display device.
In practice, an individual provides a user prompt by simply pushing the activation button 14 and the microprocessor 19 directs the physiologic sensors 13 to obtain the individual's physiologic data. The resulting comprehensive data is then combined and made available for access by the viewing device 16. Please note, however, that the microprocessor 19 may be programmed to either regularly monitor physiological variables at predefined intervals or obtain the data at a pre-defined, desired time. Furthermore, it should be appreciated by those of ordinary skill in the art that the output data may also be automatically associated with the individual's identification information by the present invention.
However, in one exemplary embodiment of the identification bracelet 10, each physiologic sensor includes its own activation mechanism and output. For example, each sensor may comprise its own activation button 14 and an output to which a display device may be connected. It may also be possible to provide a small display such as, for example, a small LCD dedicated to each sensor on the bracelet itself.
In yet another exemplary embodiment of the invention, the diagnostic identification bracelet 10 comprises a memory 30 which stores both patient identification and physiologic data. Additionally, the physiologic sensor data may modify the function of the bracelet itself. For example, if the proximity or profusion sensor determines that a swollen appendage comes in contact with the internal circumference of the bracelet 10 or is a predefined distance from the internal circumference, the microprocessor 19 may operate to automatically unlock the diagnostic identification bracelet 10. Finally, in an alternate exemplary embodiment, the bracelet 10 may communicate the same information with patient information management systems via a wired or wireless communication technology. For example, this advantageously allows the bracelet to automatically update patient records or retrieve the same for on demand display to a care provider or other individual with the viewing device.
It should be noted that various hardware and software record management systems are commercially available. Moreover, it should be appreciated that a single device, a personal digital assistant or other device capable of storing data may comprise the record management system. The diagnostic and identification bracelet 10 is coupled to the record management system 20 via a local connector 21, a wired or wireless network 22, the internet 23, a phone system 24, any combination thereof, or any other communication method used to deliver data. As a result, patient records can be regularly and accurately updated. However, it should be noted that the diagnostic and identification bracelet 10 may be programmed to repetitively communicate the physiologic data records to the record management system, transmit the same based on a user indication, or at any desired time period. Alternatively, the patient data may be transmitted via any mentioned communication method to the record management system 20 from the viewing device 16. Finally, the system may be programmed to retrieve patient's records from the system on demand so that such records are displayed to the requester via the viewing device 16.
The specific embodiments discussed in the detailed description are merely illustrative of specific ways to make and use the invention, and do not limit the scope of the invention.
