Abstract
Description
L'invention concerne un système occlusif par coulissage du cathéter sur lui-même, pour abord vasculaire nécessaire a une épuration extra corporelle type hémodialyse, échanges plasmatiques, ou a une alimentation parentérale ou injection de produits pour chimiothérapie. On connait les cathéters d'hémodialyse classiques qui comportent une extrémité intravasculaire ou se font les échanges entre sang épuré et non épuré ; cette extrémité la est toujours au contact de sang en dehors ou au cours des séances d'hémodialyse, avec le temps la fibrine se dépose au niveau des trous ou se font les échanges causant ainsi le dysfonctionnement voir l'arrêt total des échanges. The invention relates to an occlusive system by sliding the catheter on itself, for vascular first necessary for extracorporeal treatment such as hemodialysis, plasma exchange, or parenteral nutrition or injection of products for chemotherapy. Conventional hemodialysis catheters are known which have an intravascular end or exchange between purified and unpurified blood; this end is always in contact with blood outside or during hemodialysis sessions, with time the fibrin is deposited at the holes where exchanges occur causing the malfunction or see the total cessation of trade.
L'invention a pour but de réaliser un système occlusif par coulissage du cathéter sur lui-même , qui nous permettra de fermer la partie intravasculaire ou se font les échanges de sang épuré et non épuré a la fin de la séance de dialyse, a fin que cette partie là ne soit plut au contact du sang et nous évitera le dysfonctionnement du cathéter par dépôt de fibrine , et de la rouvrir au bronchement de la prochaine séance. The object of the invention is to provide an occlusive system by sliding the catheter on itself, which will allow us to close the intravascular part or exchange purified and unpurified blood at the end of the dialysis session. that this part is not pleased with the blood contact and we will avoid the dysfunction of the catheter by deposition of fibrin, and to reopen it with the bronchiality of the next session.
Fig 1 : vue du système fermé. la : vue du système fermé mis sur cathéter tunnelisé d'hémodialyse. Fig 2 : vue du système ouvert. 2a : vue du système ouvert mis sur cathéter tunnelisé 30 d'hémodialyse. Fig 3 : vue du cathéter ouvert au niveau de la veine jugulaire interne. Fig 4 : vue du cathéter ferme au niveau de la veine jugulaire interne. 35 Fig 5 : coupe sagittale du dispositif de coulissage qui permet l'ouverture et la fermeture. Sur la figure-la- le schéma représente le système occlusif fermé mis sur un cathéter monolumiere tunnelisé pour long 40 durée, comme on peut le voir la partie intravasculaire ou se trouve les trous qui permettent les échanges est recouverte, et cela grâce a un système de coulissage du cathéter sur lui-même, cela évitera le contact de la surface d'échanges du sang en dehors des séances. Fig 1: view of the closed system. the view of the closed system put on tunnelized catheter of hemodialysis. Fig 2: view of the open system. 2a: view of the open system placed on a tunneled hemodialysis catheter. Fig 3: View of the open catheter at the level of the internal jugular vein. Fig 4: view of the closed catheter at the level of the internal jugular vein. Fig 5: Sagittal section of the sliding device which allows opening and closing. In Figure 1 the diagram shows the closed occlusive system placed on a monolumeric catheter tunneled for long duration, as can be seen the intravascular portion where the holes that allow exchanges is covered, and this through a system sliding of the catheter on itself, this will avoid the contact of the blood exchange surface outside sessions.
Cette fermeture se fera par une traction douce sur la partie externe éloignant le point A du point B tout en injectant du sérum salé pour chasser le sang restant dans le cathéter et de cela rapprochement du point C du point D (figure 1). This closure will be by gentle traction on the outer part away point A from point B while injecting saline to drive the blood remaining in the catheter and this approaching point C point D (Figure 1).
Sur la figure-2a- le schéma représente le système occlusif ouvert mis sur cathéter monolumiere tunnelisé pour long durée, et dont la partie intravasculaire ou se trouve les trous qui permettent les échanges est découverte a fin de permettre les échanges de sang épuré et non épuré. In Figure-2a the diagram shows the open occlusive system placed on a monolumiere catheter tunneled for long duration, and whose intravascular part where are the holes that allow exchanges is discovered to allow exchange of purified and unpurified blood .
Cette ouverture se fera par une simple pression sur la partie externe rapprochant le point A du point B, et de cela éloignement du point C du point D (fig 2). This opening will be done by a simple pressure on the outer part bringing the point A of the point B, and this distance from the point C of the point D (fig 2).
Sur la fig 3 le schéma représente le système ouvert mis sur 20 cathéter tunnelisé pour hémodialyse dans la veine au cours d'une séance d'hémodialyse. In Fig. 3 the diagram shows the open system placed on a tunneled catheter for hemodialysis in the vein during a hemodialysis session.
Sur la fig 4 le schéma représente le système fermé mis sue cathéter tunnelisé pour hémodialyse dans la veine a la fin de 25 la séance d'hémodialyse. In Fig. 4 the diagram shows the closed system placed on the tunneled catheter for hemodialysis in the vein at the end of the hemodialysis session.
Sur la fig 5 le schéma représente une coupe sagittale nous permettons de comprendre le système de coulissage qui se fait lors de la fermeture et de l'ouverture.In Figure 5 the diagram shows a sagittal section we can understand the sliding system that is done during closing and opening.
30 Ce système occlusif par coulissage pourra être réalisé par la mise en place de deux cathéters avec une différence de diamètre qui nous permettra de glisser le cathéter externe sur le cathéter interne avec une lumière virtuelle entre eux, a 35 fin de nous permettre de fermer et d'ouvrir le cathéter. A l'intérieur du cathéter le système de coulissage se fera par l'intermédiaire de quatre rails qui se trouve le long du tuyau interne et cela pour faciliter le glissement comme on peut le voir sur la fig 5. 40 This sliding occlusive system may be achieved by placing two catheters with a difference in diameter which will allow us to slide the outer catheter onto the inner catheter with virtual light between them, to allow us to close and to open the catheter. Inside the catheter the sliding system will be via four rails which is located along the inner pipe and this to facilitate sliding as can be seen in Figure 5. 40
