  • Patent number: 7378975
    Abstract: There is provided herein a sensor/monitor combination designed to reduce the risk of pressure ulcer occurrence in immobile patients, wherein the level of patient activity is tracked to determine whether or not that patient has exhibited sufficient activity to merit eliminating a scheduled assisted relocation to a new position. The instant device senses the time since a patient last relocated into a different sitting or lying position. If the patient has not moved during some predetermined time period, the nursing staff will be notified by the invention that it is time to manually reposition the patient. If the patient has significantly changed position during the predetermined time period and, thus, allowed previously compressed tissues to reoxygenate, the invention will not signal that a move is necessary, thereby eliminating the need in some cases to rouse the patient from an otherwise healing sleep.

  • Patent number: 7319400
    Abstract: The instant invention is designed to detect when undue tension is placed on a belt or strap that is connected to a restraining vest, such undue pressure being indicative that a patient may be in trouble. It is preferable that, whatever sensor is used, it should be elastically resilient to return to its unstressed state after tension on the strap is removed. Additionally, it is preferable that the amount of force that is required in order to trigger an alarm be adjustable to accommodate patients of different weights. Finally, it is also preferable that the level of stress on the strap—and the duration over which it is applied—that is necessary to trigger an alarm be such that the patient cannot easily intentionally cause the device to sound an alarm.

  • Patent number: 7079036
    Abstract: There is provided herein a first preferred arrangement of the instant invention, wherein an electronic patient monitor utilizes a computer CPU as an alarm signal generator, which CPU is preferably directly connected to a power amplifier and/or a speaker without an intervening (or subsequent) conventional volume control. The alarm signal is preferably expressed as a series of square waves. The volume of the alarm signal as heard through the speaker is controlled by varying the width of the square waves that represent the alarm signal with the duty cycle of the square waves being shortened to reduce the output alarm volume and lengthened to increase it.

  • Patent number: 7078676
    Abstract: There is provided herein a sensor for determining relative displacement between two surfaces which utilizes two optically conductive members that have been mounted in proximity to each other, whereby the amount of displacement between the two surfaces may be determined by measurement of the magnitude of the intensity of light transmitted through them. The instant invention preferably utilizes two planar light transmitting surfaces—an emitter and a receiver—which are free to move laterally with respect to each other and are positioned so that when light is introduced into the emitter some proportion of that light falls on the receiver. By electronically monitoring the intensity of light impinging on the receiver an estimate of the amount of overlap between the two optical surfaces and, thus, an estimate of the relative displacement between them, may be obtained.

  • Patent number: 6987232
    Abstract: There is provided herein a sensor for use in connection with an electronic patient monitor, wherein the sensor preferably uses a linearly configured resistive ladder with spaced-apart resistors as a means of determining at least approximately a location of the patient on the sensor as well as an approximate length of the sensor which is compressed by the patient. By continuously determining both of these quantities over time it is possible to track the patient's movement and determine to what extent the patient needs to be manually turned and/or the extent to which a next-scheduled turn can be skipped.

  • Patent number: 6897781
    Abstract: According to a preferred embodiment, there is provided an electronic patient monitor for use in reducing the risk of decubitus ulcers. The monitor utilizes a separate sensor which senses the position of the patient in the bed or chair for purposes of determining when the patient moves. Additionally, the monitor broadcasts masking noise through its own, or through a remote, speaker, thereby enabling the patient to rest more comfortably in a noisy institutional environment. If the patient does not move on his or her own accord within a predetermined turn interval, the masking sound broadcast will be terminated which will gently encourage the patient to move. An alarm may additionally be sounded to notify the caregiver that the patient needs to be manually turned to reduce the risk of decubitus ulcers.

  • Patent number: 6544200
    Abstract: There is provided herein an electronic patient monitor that is suitable for use with a variety of different sensors and which automatically configures itself depending on the sensor that is used and/or the environment in which the electronic monitor is placed. In a first preferred embodiment, the electronic monitor determines whether it is being used on a bed or a chair by sensing whether or not a nurse call connector is present. If such a connector is plugged into the monitor, the unit will assume that it is being used with a sensor that has been placed on a bed and will configure its internal parameters appropriately. Such configuration would include changing a delay time to provide for longer delays before sounding an alarm than would be used with a chair monitor.
