Description

LIT MÉDICALISÉ MEDICAL BED
La présente invention se rapporte à un lit médicalisé pour des personnes ayant des problèmes de mobilité notamment des personnes incapables de se déplacer et devant rester alités dans pour des périodes prolongées. Dans les lits conventionnels pour des personnes valides, un matelas est placé sur un cadre. Pour des personnes invalides, un tel agencement ne permet pas une bonne circulation du sang. The present invention relates to a medical bed for people with mobility problems, in particular people who are unable to move and who have to stay in bed for long periods. In conventional beds for able-bodied people, a mattress is placed on a frame. For invalids, such an arrangement does not allow good blood circulation.
Les personnes invalides ressentent alors un inconfort et ont besoin de se tourner. Malgré des dispositifs permettant une vibration du matelas, la circulation du sang est gênée, et apparaissent très vite des rougeurs, de l’eczéma, des escarres ou des problèmes digestifs. Disabled people then feel discomfort and need to turn around. Despite devices allowing the vibration of the mattress, the circulation of blood is hampered, and very quickly appear redness, eczema, bedsores or digestive problems.
Afin d'empêcher ou de retarder au maximum ces problèmes, le personnel médical, régulièrement, retourne ou fait changer de position la personne invalide sur son lit. Par exemple, FR2750041 décrit un lit comprenant deux cadres qui tournent latéralement pour aider à faire tourner le patient. Chaque cadre comprend un arbre monté parallèlement à l'axe longitudinal d'un cadre de base du lit. Plusieurs lattes espacées sont montées parallèlement les unes aux autres sur l'arbre. Les lattes sont positionnées dans les espaces entre les lattes fixes et mobiles du lit et tournent lorsqu'elles sont déplacées par l'arbre. Un système d'entraînement déplace l'arbre. En faisant varier les parties du corps du patient sur lesquelles la pression est appliquée, les cadres aident à faire tourner le patient et à modifier sa position de repos. In order to prevent or delay these problems as much as possible, the medical personnel regularly turn the disabled person over or change his position on his bed. For example, FR2750041 describes a bed comprising two frames which rotate laterally to help turn the patient. Each frame includes a shaft mounted parallel to the longitudinal axis of a bed base frame. Several spaced slats are mounted parallel to each other on the shaft. The slats are positioned in the spaces between the fixed and moving slats of the bed and rotate when moved by the shaft. A drive system moves the shaft. By varying the parts of the patient's body on which pressure is applied, the frames help rotate the patient and alter their resting position.
Des ressources humaines et matérielles sont utilisées, et la charge psychologique est forte pour le patient. Human and material resources are used, and the psychological burden is high for the patient.
La demande de brevet internationale, publiée sous le numéro WO2014114367A1 , décrit un lit mobile de soins intensifs comprenant : un cadre porteur ; deux tiges longitudinales reliées au cadre porteur et placées parallèlement aux côtés gauche et droit du lit ; des supports de dos et de cuisses reliés aux tiges précitées par des articulations ; repose-jambes reliés à la partie cuisse par des charnières ; des actionneurs pour actionner les supports du dos, des cuisses et des jambes ; et une plate-forme de lit radio transparente avec une capacité de poids maximale élevée. Le lit mobile est proposé comme solution à un problème spécifique qui se manifeste lorsque l’on cherche à faire des radiographies pendant que le patient est dans le lit. Les actionneurs sont donc placés de part et d'autre du lit, à l'extérieur des deux tiges longitudinales de manière à laisser un espace vide entre et en dessous desdites tiges. Cela permet de scanner aux rayons X n'importe quelle partie du corps du patient, alors que le patient est allongé sur le lit, ceci sans que les actionneurs n’interfèrent avec les rayons X. The international patent application, published under the number WO2014114367A1, describes a mobile intensive care bed comprising: a carrier frame; two longitudinal rods connected to the support frame and placed parallel to the left and right sides of the bed; back and thigh supports connected to the aforementioned rods by joints; leg rests connected to the thigh part by hinges; actuators to operate the back, thigh and leg supports; and a transparent radio bed platform with a high maximum weight capacity. The mobile bed is offered as a solution to a specific problem that arises when trying to take x-rays while the patient is in bed. The actuators are therefore placed on either side of the bed, outside the two longitudinal rods so as to leave an empty space between and below said rods. This allows any part of the patient's body to be scanned with X-rays, while the patient is lying on the bed, without the actuators interfering with the X-rays.
La demande de brevet européenne, numéro de publication EP1028684A1 , divulgue une table chirurgicale articulée comportant des moteurs pour modifier les positions des différentes parties articulées de la table entre elles. Un chirurgien peut ainsi modifier la configuration de la table, avec une télécommande, pour mettre un patient dans une position la plus appropriée pour l’intervention prévu sur le patient. La demande de brevet japonaise, numéro de publication JP2000334004A divulgue Le lit se compose d'au moins un dossier, un siège et deux repose-pieds. Une cuvette de toilette est disposée sous le siège, et en face du dossier est disposé une rondelle, ou pommeau de douche, qui décharge un fluide à haute pression. Un passage d'air comprimé est agencé à l'intérieur du dossier et la surface du dossier comporte des trous d'évacuation pour l'air comprimé. Le lit est conçu pour le confort du patient et pour faciliter le travail du soignant du patient. Pour prévenir l'apparition d'escarres, de l’air comprimé est déchargé par les trous dans la surface du dossier pour soulever momentanément le patient du dossier. Le pommeau de douche permet au soignant de laver le patient facilement et d’enlever des matières organiques avec efficacité. The European patent application, publication number EP1028684A1, discloses an articulated surgical table comprising motors for modifying the positions of the various articulated parts of the table between them. A surgeon can thus modify the configuration of the table, with a remote control, to put a patient in the most appropriate position for the planned intervention on the patient. Japanese patent application, publication number JP2000334004A discloses The bed consists of at least a backrest, a seat and two footrests. A toilet bowl is arranged under the seat, and in front of the backrest is arranged a washer, or shower head, which discharges a fluid at high pressure. A passage for compressed air is arranged inside the backrest and the surface of the backrest has exhaust holes for the compressed air. The bed is designed for patient comfort and to facilitate the work of the patient's caregiver. To prevent the occurrence of pressure sores, compressed air is discharged through holes in the surface of the backrest to momentarily lift the patient from the backrest. The showerhead allows the caregiver to wash the patient easily and remove organic matter efficiently.
Le but de la présente invention est de procurer un lit qui permet à la personne invalide d’être autonome dans les déplacements de parties de son corps pour modifier de façon permanente les points de pression sur le corps, améliorer la circulation du sang afin d'empêcher des escarres. The object of the present invention is to provide a bed that allows the disabled person to be independent in moving parts of his body to permanently modify the pressure points on the body, improve blood circulation in order to prevent bedsores.
Conformément à l’invention, un lit médicalisé pour un patient, comprend :In accordance with the invention, a medical bed for a patient comprises:
- un châssis de base, s’étendant le long d’un plan horizontal ; - a base frame, extending along a horizontal plane;
- un dossier de forme rectangulaire mobile vers le haut, vers le bas, et selon différents angles inclinés par rapport au plan horizontal, le dossier étant disposé sur un moyeu fixé sur le châssis de base, le dossier comportant à deux côtés opposées des supports de bras mobiles, le dossier comportant en outre sur un troisième côté une têtière agencée pour maintenir la tête d’un patient, et sur le quatrième côté, une assise prolongée par des supports de jambes mobiles agencés pour supporter des jambes d’un patient. - a rectangular-shaped backrest movable upwards, downwards, and at different inclined angles relative to the horizontal plane, the backrest being arranged on a hub fixed to the base frame, the backrest comprising on two opposite sides mobile arm supports, the backrest further comprising on a third side a headrest arranged to hold the head of a patient, and on the fourth side , a seat extended by movable leg supports arranged to support the legs of a patient.
Le lit comporte un moteur individuel pour le déplacement de la têtière, et deux paires de deux moteurs pour chaque support de jambe, chacun étant pilotable individuellement pour empêcher la formation d’escarres. The bed has an individual motor for moving the headrest, and two pairs of two motors for each leg support, each individually controllable to prevent pressure sores from forming.
Le lit médicalisé comporte un dispositif de récupération de matières organiques. The medical bed includes a device for recovering organic matter.
Selon une forme d’exécution préférentielle, l’assise du lit comporte une rainure de manière à permettre au patient de se mettre en position assise avant de faire ses besoins, position qui facilite grandement l’évacuation des matières organiques du corps du patient. Ainsi, toujours selon cette forme d’exécution préférentielle, un tube peut être disposé dans la rainure pour connecter la rainure de l’assise au dispositif de récupération de matières organiques. According to a preferred embodiment, the seat of the bed has a groove so as to allow the patient to sit in a sitting position before doing his business, a position which greatly facilitates the evacuation of organic matter from the patient's body. Thus, still according to this preferred embodiment, a tube can be arranged in the groove to connect the groove of the seat to the device for recovering organic materials.
Dans une forme d’exécution, le lit médicalisé comporte une commande générale agencée pour piloter chaque moteur ou chaque groupe de moteurs. Ainsi un patient peut choisir de déplacer une jambe plutôt qu’une autre, redresser le dossier sans pour autant déplacer les jambes,... Le patient gère les déplacements des parties du lit afin de pouvoir se sentir à l’aise dans chaque position et permettre une meilleure circulation du sang. In one embodiment, the medical bed comprises a general control arranged to drive each motor or each group of motors. Thus a patient can choose to move one leg rather than another, straighten the backrest without moving the legs,... The patient manages the movements of the parts of the bed in order to be able to feel comfortable in each position and allow better blood circulation.
Dans une forme d’exécution, le lit comporte des éléments de maintiens, notamment une sangle ou une barre pour maintenir l’utilisateur en position pendant des déplacements d’une partie du lit. En effet, en fonction du type de handicape de la personne, il peut être utile de sécuriser le patient lors de déplacements, notamment par la présence d’une sangle autour de la taille ou autour des cuisses. In one embodiment, the bed comprises holding elements, in particular a strap or a bar to hold the user in position during movements of part of the bed. Indeed, depending on the type of disability of the person, it may be useful to secure the patient when moving, in particular by the presence of a strap around the waist or around the thighs.
Afin de donner la plus grande mobilité possible, le dossier est agencé pour passer d’une position horizontale jusqu’à une position essentiellement verticale de manière à redresser un patient, jusqu’à un angle d’environ 90° par rapport au plan horizontal. Ainsi, le patient peut passer d’une position couchée à une position quasi- redressée voire debout. In order to give the greatest possible mobility, the backrest is arranged to pass from a horizontal position to an essentially vertical position from so as to straighten a patient, up to an angle of approximately 90° with respect to the horizontal plane. Thus, the patient can move from a lying position to a quasi-straightened or even standing position.
De manière à éviter les points de pressions sur le dos et les jambes, le dossier et le moyeu sont reliés par des moteurs agencés pour incliner le dossier selon un axe de rotation transversal au plan horizontal, typiquement entre 20° et 45°. Ainsi, tel un simulateur de vol, le lit peut s’incliner pour que le poids du patient puisse passer d’un côté à l’autre et faciliter la circulation du sang dans le corps. In order to avoid pressure points on the back and the legs, the backrest and the hub are connected by motors arranged to tilt the backrest along an axis of rotation transverse to the horizontal plane, typically between 20° and 45°. Thus, like a flight simulator, the bed can tilt so that the weight of the patient can pass from one side to the other and facilitate the circulation of blood in the body.
Dans une forme d’exécution, chaque support de bras mobile est agencé pour être déplacé par un moteur. Ainsi, un patient peut librement déplacer un bras ou un autre voir les deux en même temps. In one embodiment, each mobile arm support is arranged to be moved by a motor. Thus, a patient can freely move one arm or the other or see both at the same time.
Pour passer d’une position couchée à une position assise et inversement, le lit comporte deux moteurs positionnés dans le même axe, les moteurs reliant le dossier au châssis de base. Afin de faciliter les soins ou de donner plus de confort au patient, le lit comporte deux moteurs agencés pour relier le châssis de base et le moyeu de manière à redresser le lit dans une position verticale. To go from a lying position to a sitting position and vice versa, the bed has two motors positioned in the same axis, the motors connecting the backrest to the base frame. In order to facilitate the care or to give more comfort to the patient, the bed comprises two motors arranged to connect the base frame and the hub so as to raise the bed in an upright position.
