Prospección tecnológica de patentes relacionadas con el seguimiento de accidentes por caídas en hospitales

Autoría SCIMAGO INSTITUTIONS RANKINGS

RESUMEN

Objetivos:

mapear la producción de tecnologías destinadas al monitoreo de caídas en un ambiente hospitalario protegido por patentes registradas.

Métodos:

prospección tecnológica de patentes internacionales, con enfoque cuantitativo, con búsqueda realizada entre febrero y marzo de 2022 en la base de datos Derwent Innovations Index con los descriptores caída, hospital, monitoreo.

Resultados:

se encontraron 212 patentes, la mayoría presentadas y publicadas desde 2010, por Tran B (9) y Cerner Innovation Inc (9), enfocadas en tecnología de la salud. Las universidades fueron responsables del 13% de los depósitos. Hubo predominio de registros de Estados Unidos (43,4%), China (21,7%) y Japón (12,3%), además de estrategias tecnológicas catalogadas como dispositivos ambientales (80,7%) y para prevenir caídas (66,5%), así como la tendencia hacia recursos con múltiples funcionalidades en una misma tecnología.

Conclusiones:

la pluralidad de funciones en un mismo dispositivo refleja la búsqueda de optimización de recursos y la preocupación por la atención integral.

Descriptores:
Accidentes por Caídas; Tecnología; Patente; Hospitales; Invenciones

Seq	Country	Patent title	Description	Type of technology	Nº of citations
D01	USA	Heart monitoring system for use by e.g. doctor, has wearable appliance with wireless transceiver to monitor patient movement, where heart disease recognizer transmits heart sound to remote listener if recognizer identifies problem	Cardiac monitoring system for medical use. It has a wearable device with a wireless transceiver to monitor patients’ movement and a heart disease recognition device that transmits the sound of the heart for the remote listener to identify the problem.	Wearable device	245
D02	USA	Monitoring device for detecting presence or absence of person in bed, has alarm that is actuated when characteristics such as relative position, velocity, acceleration exceeds preset threshold values	Monitoring device to detect the presence or absence of a person in the bed. It has an alarm that is triggered when characteristics such as relative position, speed and acceleration exceed predefined limit values.	Environmental monitoring device	164
D03	USA	Processing system for medical devices used for monitoring vital signs and motion for e.g. patient has processing component to determine alarm rule, determined by collectively processing first and second alarm conditions with alarm algorithm	Processing system for medical devices used to monitor vital signs and movement. It has a processing component to determine the alarm rule.	Wearable device	128
D04	USA	Healthcare monitoring system for e.g. hospital, has monitor with sensors to detect physiological data, location and status of wearer of monitor, with processing and storage capabilities for processing and storing data	Health monitoring system. It has a monitor with sensors to detect physiological data, location and user status, with data processing and storage capabilities.	Wearable device	114
D05	USA	Wireless monitoring system for bedridden patients in nursing home, has weight sensor pad to produce signal, when patient rises from bed, to activate alarm indicating patient room number in nurses station	Wireless monitoring system for bedridden patients. It has a weight sensor to produce a signal when patients get up from the bed, activating the alarm and indicating the patients’ room number at the nursing station.	Environmental monitoring device	102
D06	USA	Wireless physiological sensor for measuring acceleration of patient has first aperture of base and first through-hole via of substrate layer filled with at least thermally conductive material	The wireless physiological sensor to measure patient acceleration. It can be used as a wearable wireless sensor for pressure ulcer risk, fall detection or fall risk. The patient monitor sounds an alarm or alert to notify caregivers of the identified risk in an effort to anticipate and therefore prevent a patient fall when the patient monitor determines that patients’ fall risk is above a predetermined limit.
