Description

Pompe à nutrition asservie
La présente invention concerne une pompe à nutrition asservie et telécommandée. Slave nutrition pump
The present invention relates to a servo-controlled and remote-controlled nutrition pump.

Depuis la mise au point, il y a une dizaine d'années, de pompes à nutrition dites "nutri-pompes", de nombreuses publications scientifiques ont montré l'intérêt et l'importance de ces dispositifs dans les cas où la nutrition parentérale ou buccale est défaillante et inutilisable. Since the development, ten years ago, of nutrition pumps called "nutri-pumps", numerous scientific publications have shown the interest and the importance of these devices in cases where parenteral nutrition or mouth is faulty and unusable.

Cependant les appareils actuellement commercialisés et utilisés présentent un certain nombre d'inconvénients que l'on peut énoncer comme suit
- mauvaise agitation (donc homogénéité) du liquide nutritif,
- reproductibilité et fiabilité incertaines du débit du liquide nutririf dues à l'utilisation d'une pompe de type péristaltique,
- absence totale d'un programme d'alimentation du malade en fonction de ses besoins physiologiques et de ses -possibilités d'assimilation,
- nécessité de manipulation des appareils par un personnel hautement spécialisé.However, the devices currently marketed and used have a certain number of drawbacks which can be stated as follows
- poor agitation (therefore homogeneity) of the nutritive liquid,
- uncertain reproducibility and reliability of the flow of the nutritive liquid due to the use of a peristaltic type pump,
- total absence of a feeding program for the patient according to his physiological needs and his possibilities of assimilation,
- need for handling of the devices by highly specialized personnel.

La présente invention vise à surmonter ces divers inconvénients; cette invention est essentiellement fondée sur les deux constatations suivantes
- il est possible grâce à un choix de mesures simples d'adapter l'alimentation du malade aux besoins physiologiques et aux possibilités d'assimilation de ce malade,
- il est souhaitable en fonction des mesures ainsi réalisées de disposer d'un appareil présentant d'une part, un asservissement aux résultats des mesures et d'autre part, d'une télécommande permettant un contrôle aisé à distance. The present invention aims to overcome these various drawbacks; this invention is essentially based on the following two findings
- it is possible thanks to a choice of simple measures to adapt the diet of the patient to the physiological needs and the possibilities of assimilation of this patient,
- It is desirable, depending on the measurements thus carried out, to have a device having, on the one hand, a slave to the results of the measurements and, on the other hand, a remote control allowing easy remote control.

Les mesures choisies sont
- d'une part, une mesure de la résistivité du milieu gastrique et du milieu intestinal,
- d'autre part, une mesure de la pression au niveau stomacal et au niveau intestinal.The measures chosen are
- on the one hand, a measure of the resistivity of the gastric medium and the intestinal medium,
- on the other hand, a measurement of the pressure at the stomach level and at the intestinal level.

La mesure de la résistivité a été choisie car d'une part, les appareils permettant d'effectuer cette mesure sont connus et utilisables dans une pompe à nutrition et d'autre part, elle permet d'avoir une idée relativement précise de l'osmolarité et de l'acidité ou de l'alcalinité du milieu. Cette derniere notion a été retenue comme celle permettant de pallier au maximum des inconvénients rencontrés dans les dispositifs actuels et liés à une mauvaise adaptation de l'alimentation artificielle aux besoins et aux possibilités d'assimilation des malades.La conséquence de ce choix est que, en fonction des mesures de résistivité effectuées en milieu gastrique et intestinal, il faudra pouvoir adapter l'alimentation du malade d'où la nécessité de disposer de deux réserves alimentaires, l'une contenant un liquide nutritif hyperosmolaire et l'autre contenant un liquide nutritif hypoosmolaire et de deux pompes qui seront asservies aux résultats des mesures. The resistivity measurement was chosen because on the one hand, the devices making it possible to carry out this measurement are known and usable in a nutrition pump and on the other hand, it allows to have a relatively precise idea of the osmolarity and the acidity or alkalinity of the medium. The latter notion has been retained as that making it possible to overcome as much as possible the drawbacks encountered in current systems and linked to a poor adaptation of artificial feeding to the needs and possibilities of assimilation of patients. The consequence of this choice is that, depending on the resistivity measurements carried out in the gastric and intestinal medium, it will be necessary to be able to adapt the patient's diet, hence the need for two food reserves, one containing a hyperosmolar nutritive liquid and the other containing a nutritive liquid hypoosmolar and two pumps which will be controlled by the measurement results.

La mesure de la pression a été choisie car c'est elle qui permet le mieux d'illustrer l'état, à tout moment, de l'estomac et de l'intestin (état de remplissage et vitesse d'écoulement pour ces deux organes). D'autre part, les appareils permettant de réaliser cette mesure (les différences de pression à mesurer sont de l'ordre de quelques centimètres d'eau) sont courants et suffisamment miniaturisables pour être mis en place au niveau (stomacal et intestinal) souhaité.  The pressure measurement was chosen because it is the one that best illustrates the state, at all times, of the stomach and intestine (filling state and flow speed for these two organs ). On the other hand, the devices making it possible to carry out this measurement (the pressure differences to be measured are of the order of a few centimeters of water) are common and sufficiently miniaturizable to be placed at the desired level (stomach and intestinal).

Cette mesure de pression conditionnera le débit total du liquide alimentaire à chaque in##stant; il y aura donc asservissement des deux pompes aux résultats des mesures de pression effectuées. This pressure measurement will condition the total flow of liquid food to each in ## stant; there will therefore be enslavement of the two pumps to the results of the pressure measurements carried out.

Par ailleurs il convient de faire en sorte que les débits des pompes qui transfèrent les/ou le liquides alimentaires soient réglés aussi exactement que possible. Pour cela il a été trouvé d'une part, qu'il était utile d'utiliser non pas des pompes péristaltiques mais des pompes à pistons qui sont par ailleurs plus fiables et d'autre part qu'il y avait en général intérêt à agiter les liquides nutritifs. Enfin, dans les centres de soins, les résultats des diverses mesures, le fonctionnement des pompes et l'état instantané des réserves alimentaires disponibles dans les appareils d'alimentation pourront avantageusement être regroupés dans une salle de contrôle ou un même surveillant pourra être ainsi responsable du bon fonctionnement de plusieurs pompes à nutrition selon l'invention. In addition, care should be taken to ensure that the flow rates of the pumps which transfer the food liquids are adjusted as exactly as possible. For this it was found on the one hand, that it was useful to use not peristaltic pumps but piston pumps which are moreover more reliable and on the other hand that there was in general interest to agitate nutritious liquids. Finally, in health centers, the results of the various measurements, the operation of the pumps and the instantaneous state of the food reserves available in the feeding devices can advantageously be grouped in a control room or the same supervisor can thus be responsible. the proper functioning of several nutrition pumps according to the invention.

Le dispositif, pompe à nutrition selon l'invention ayant donc réserve alimentaire liquide, et pompe de distribution de ladite réserve dans une sonde admise-dans l'estômac #'un malade est caractérisé en ce qu'il comporte
- deux réserves de liquides nutritifs, l'un de ces liquides étant hyperosmolaire et l'autre etant hypoosmolaire, lesdits liquides étant de préférence constamment agités,
- deux pompes à piston commandées indépendamment et permettant le contrôle des débits de chacun des liquides nutritifs,
- des dispositifs permettant la mesure de la résistivité du milieu stomacal et intestinal,
- des dispositifs permettant la mesure de la pression au niveau stomacal et intestinal.
