Researchers Submit Patent Application, "Patient Movement Notification Device", for Approval

August 27, 2014



By a News Reporter-Staff News Editor at Electronics Newsweekly -- From Washington, D.C., VerticalNews journalists report that a patent application by the inventor Eddy, Patrick E. (Allendale, MI), filed on February 3, 2014, was made available online on August 14, 2014.

The patent's assignee is Parasol Medical LLC.

News editors obtained the following quote from the background information supplied by the inventors: "The present invention generally relates to a patient movement notification device, and more specifically relates to a patient movement notification device for preventing the patient from falling.

"Patient movement notification devices serve to notify a patient's caretaker(s) who may better assist them. Such devices are used for patients who are at a high risk for fall related injury or for patients who are not healthy enough to stand (post-operative patients, etc. . . . ).

"Patient movement notification devices are currently in use that include a disposable sensor that is positioned between the patient and a bed or chair, and an electronics module that connects to the sensor for generating an alarm when the patient removes pressure from the pad by getting out of bed or up from a chair. The alarm may be a recorded vocal command, such as 'please stay in bed and use the nurse call button if you need assistance' or any other message that the caretaker may wish to record. Unlike the sensor portion, the electronics module is not disposable. The electronics module includes a plug receptacle for receiving the plug on the end of a cord that is permanently secured to the sensor.

"Existing patient movement notification devices suffer from several drawbacks. The sensors are considered to be disposable and are typically only to be used for 15 days or less because the sensors are pressure sensitive and after having pressure continuously applied to the sensor, the sensor may not be able to re-expand when the patient removes pressure. However, hospitals have difficulty monitoring the times of use such that the sensors are often used well beyond the permitted 15 day lifetime. In addition, the electronics module component is considered a capital asset and therefore must be tracked and service must be performed on it once a year regardless of whether the module even needs service."

As a supplement to the background information on this patent application, VerticalNews correspondents also obtained the inventor's summary information for this patent application: "According to an embodiment of the present invention, a disposable patient movement notification device is provided comprising: a sensor pad for sensing movement of a patient and generating a signal when movement of the patient is sensed, and an electronics module electrically coupled to the sensor pad for generating a notification of patient movement in response to receipt of the signal from the sensor pad indicating movement of the patient, wherein the electronics module permanently shuts down to become non-functional a specified time period after activation.

"According to another embodiment of the present invention, a disposable patient movement notification device is provided comprising: a sensor pad for sensing movement of a patient and generating a signal when movement of the patient is sensed, and an electronics module electrically coupled to the sensor pad for generating a notification of patient movement in response to receipt of the signal from the sensor pad indicating movement of the patient. The electronics module comprising: a housing including a slot opening into an interior of the housing; a battery contact terminal disposed in the housing; at least one battery disposed in the housing for powering the electronics module when a first end thereof is electrically coupled to the battery contact terminal; and a tab extending between the first end of the at least one battery and the battery contact terminal and extending out from the housing through the slot, wherein the tab prevents the electronics module from receiving power until such time as a user pulls the tab from the slot.

"According to another embodiment of the present invention, a disposable patient movement notification device is provided comprising: a sensor pad for sensing movement of a patient and generating a signal when movement of the patient is sensed, and an electronics module electrically coupled to the sensor pad for generating a notification of patient movement in response to receipt of the signal from the sensor pad indicating movement of the patient. The electronics module comprising: a housing, and at least one battery disposed in the housing for powering the electronics module, wherein the housing is sealed so as to prevent access to the at least one battery.

"According to another embodiment of the present invention, a sensor pad is provided for use in a patient movement notification device, the sensor pad comprising: a plastic sheet having conductive ink printed on a surface thereof to form at two conductive contacts; two wires each secured to a respective one of the conductive contacts; a foam substrate provided over one of the conductive contacts, wherein the plastic sheet is folded and sealed such that the conductive contacts face one another with the foam substrate disposed therebetween.

"According to another embodiment of the present invention, a patient movement notification device is provided comprising: a sensor pad for sensing movement of a patient and generating a signal when movement of the patient is sensed, and an electronics module electrically coupled to the sensor pad for generating a notification of patient movement in response to receipt of the signal from the sensor pad indicating movement of the patient, wherein the electronics module comprises a housing, wherein outer surfaces of at least one of the housing and the sensor pad are coated with an antimicrobial treatment, and wherein the antimicrobial treatment comprises a silane quaternary ammonium salt including an organofunctional silane covalently bonded to the outer surfaces.

"According to another embodiment of the present invention, a patient movement notification device is provided comprising: a sensor pad for sensing movement of a patient and generating a signal when movement of the patient is sensed, and an electronics module. The electronics module comprising: a microphone for receiving audible notifications, converting the audio notifications into recorded audio signals; a memory for storing recorded audio signals received from the microphone; an audio amplifier for amplifying recorded audio signals received from the memory; a speaker for converting an amplified recorded audio signals received from the audio amplifier into an audible notification; and a controller electrically coupled to the sensor pad, the memory, and the audio amplifier for causing recorded audio signals to be provided from the memory to the audio amplifier so as to generate an audible notification from the speaker in response to receipt of the signal from the sensor pad indicating movement of the patient, wherein the audio amplifier is powered down when not in use to minimize power draw.

"According to another embodiment of the present invention, a patient movement notification device is provided comprising: a sensor pad for sensing movement of a patient and generating a signal when movement of the patient is sensed, and an electronics module. The electronics module comprising: a controller electrically coupled to the sensor pad, for providing a notification in response to receipt of the signal from the sensor pad indicating movement of the patient, wherein the controller sleeps in a low power consuming state and wakes up at regular intervals to poll user interface information and when a signal is received from the sensor pad.

"These and other features, advantages, and objects of the present invention will be further understood and appreciated by those skilled in the art by reference to the following specification, claims, and appended drawings.
