Patient visualization system
(57) Abstract

A patient visualization system having a processor, communicatively coupled to a pressure sensor device to periodically receive pressure sensor data experienced by a subject at locations on the pressure sensor device. The processor programmed to receive input indicative of an intervention resulting in a pressure lowering of a body area of the subject during a first high-pressure situation at a first time; and responsive to determining a second high-pressure situation at the body area of the subject at a second time later than the first time, display an indication of the input of the intervention in connection with the first high-pressure situation.

  2. The system of claim 1, wherein the machine instructions when executed by the computer implement the following function: prompt for the input of the intervention action upon detecting the pressure lowering of the body area of the subject to end the first high-pressure situation.
  3. The system of claim 2, wherein the input of the intervention action is received from a caregiver, the subject or an individual associated with the subject.
  4. The system of claim 1, wherein the machine instructions when executed by the computer implement the following function: prompt for the input of the intervention action upon detecting the intervention action resulting in the pressure lowering of the body area of the subject to end the first high-pressure situation.
  5. The system of claim 4, wherein the input of the intervention action is received from a caregiver, the subject or an individual associated with the subject.
  6. The system of claim 1, wherein the machine instructions when executed by the computer implement the following function: detect the intervention action during the first high-pressure situation.
  7. The system of claim 1, wherein the intervention action is a subject movement, adjustment or readjustment.
  8. The system of claim 1, wherein the machine instructions when executed by the computer implement the following function: detect a reduction in pressure on the body area to end the first high-pressure situation without a corresponding change in a body position of the subject.
  9. The system of claim 1, wherein the intervention action is selected from a user interface.
  10. The system of claim 1, wherein the machine instructions when executed by the computer implement the following function: store the intervention action as a historical record of the subject.
  11. A non-transitory computer-readable medium having computer-readable instructions stored thereon that are configured to be executed by a computer to: receive an input of an intervention action, the input and intervention action being received during a first high-pressure situation at a first time, the intervention action resulting in a pressure lowering of a body area of a subject to end the first high-pressure situation, the first high-pressure situation comprises a first time period, and the first time is during the first time period; and responsive to determining a second high-pressure situation at the body area of the subject at a second time later than the first time, display the intervention action during the second high-pressure situation, the intervention action resulting in a second pressure lowering of the body area of the subject to end the second high-pressure situation, the second high-pressure situation comprises a second time period, and the second time is during the second time period.
  12. The non-transitory computer-readable medium of claim 11, wherein the computer-readable instructions are further configured to be executed by the computer to prompt for the input of the intervention action upon detecting the pressure lowering of the body area of a subject to end the first high-pressure situation.
  13. The non-transitory computer-readable medium of claim 11, wherein the computer-readable instructions are further configured to be executed by the computer to prompt for the input upon detecting the intervention action resulting in the pressure lowering of the body area of a subject to end the first high-pressure situation.
  14. The non-transitory computer-readable medium of claim 11, wherein the computer-readable instructions are further configured to be executed by the computer to detect the intervention action during the first high-pressure situation.
  15. The non-transitory computer-readable medium of claim 11, wherein the intervention action is a subject movement, adjustment or readjustment.

Description

Aspects of the disclosure generally relate to a patient visualization system in connection with pressure injuries.

Pressure injuries, otherwise known as decubitus ulcers, pressure ulcers or bedsores, are lesions developed when a localized area of soft tissue of a subject is compressed between a bony prominence and an external surface for a prolonged period of time. Pressure injuries could appear in various areas of the body, such as elbows and knees. Development of pressure injuries based on a combination of factors, such as, unrelieved pressure, friction, shearing forces, humidity, and temperature.

Hospitalized patients often suffer from pressure injuries. However, pressure injuries are not limited to hospitalized patients. Individuals confined to wheelchairs are prone to suffer from pressure injuries, especially in their pelvis, lower back, and ankles. Although easily preventable or treatable if found early, if a pressure injury lingers, it becomes painful and treatment is both difficult and expensive. In many cases, pressure injuries can prove fatal, even under the auspices of medical care. According to one estimate, 2.5 million people suffer from pressure injuries in the United States each year, resulting in over 60,000 deaths annually.

An effective way of dealing with pressure injuries is to prevent their formation. A common preventive approach is maintaining a strict routine of repositioning, e.g., rotating and/or turning, a subject to offload, to eliminate, to alleviate and/or to reduce pressure every two (2) to three (3) hours.
