DISPOSITIVO DE EXTRACCIÓN DE RESIDUOS SÓLIDOS POR VIA RECTAL SECTOR DE LA TÉCNICA RECTAL SOLID WASTE EXTRACTION DEVICE TECHNIQUE SECTOR

La presente invención se inscribe dentro del campo de los dispositivos de asistencia sanitaria, en concreto los dispositivos de facilitación de las evacuaciones de los fluidos corporales. The present invention falls within the field of healthcare devices, specifically devices to facilitate the evacuation of body fluids.

ANTECEDENTES DE LA INVENCIÓN BACKGROUND OF THE INVENTION

Existen diversas situaciones en la que las personas necesitan asistencia en la evacuación de sus residuos sólidos orgánicos o heces fecales. Ejemplos de ello son las personas con movilidad reducida, personas mayores y enfermos con patologías intestinales que precisan de algún tipo de asistencia en la realización de la necesaria extracción dichos residuos intestinales. There are several situations in which people need assistance in the evacuation of their organic solid waste or faeces. Examples of this are people with reduced mobility, the elderly and patients with intestinal pathologies who require some type of assistance in carrying out the necessary extraction of said intestinal residues.

El método habitualmente empleado en el ámbito hospitalario y sanitario en general es un recipiente abierto denominado comúnmente cuña que precisa de la intervención directa del personal asistencial. En otros ámbitos es frecuente el empleo de elementos absorbentes, como pañales o similares. Ambos sistemas no son eficientes en el caso de pacientes que no pueden realizar esfuerzos abdominales. The method usually used in the hospital and health field in general is an open container commonly called a wedge that requires the direct intervention of healthcare personnel. In other areas, the use of absorbent elements, such as diapers or the like, is common. Both systems are not efficient in the case of patients who cannot perform abdominal efforts.

Existen dispositivos denominados sondas para la orina y residuos líquidos que se insertan a través de los esfínteres. Existen también sondas rectales con diversos objetivos, pero no existen sistemas eficientes para la extracción de los residuos sólidos sin la intervención directa de personal asistencial. There are devices called catheters for urine and liquid waste that are inserted through the sphincters. There are also rectal probes with various objectives, but there are no efficient systems for the extraction of solid waste without the direct intervention of healthcare personnel.

Esta intervención directa del personal asistencial, tanto en los ámbitos hospitalarios como geriátricos o particulares, en un espacio de la intimidad de las personas como éste, tiene en muchas ocasiones una repercusión en la autoestima de los pacientes. This direct intervention of healthcare personnel, both in hospital and geriatric or private settings, in a space of personal intimacy such as this one, often has an impact on the self-esteem of patients.

Por otra parte, la limitación de recursos humanos asistenciales también puede incidir en una ineficiencia en la realización de este tipo de tareas que podría ser compensada con el empleo de dispositivos mecánicos, pudiendo aumentar además los estándares de calidad del servicio. On the other hand, the limitation of healthcare human resources can also lead to inefficiency in carrying out this type of task, which could be compensated with the use of mechanical devices, being able to also increase the service quality standards.
