Dispositivo ago catetere con più fori Catheter needle device with multiple holes
DESCRIZIONE E FINALITÀ DESCRIPTION AND PURPOSE
Nelle applicazioni industriali e soprattutto mediche il sistema, o il corpo sono costituiti da componenti da componenti o organi che possono richiedere l'inserimento o l'estrazione di materiali o sostanze con precisione e nel rispetto di quantità ed ubicazioni mediante la penetrazione di aghi come nel caso medicale, ad esempio, in cui spesso è necessario estrarre sostanze o inserire medicine in particolari organi ed in particolari posizioni. Lo stato dell'arte più prossimo alla soluzione proposta è costituito dal brevetto CN1056818 “Puncture probe with multi-porous bulb-headed catheter” che descrive con un ago per puntura medica la suzione di emorragia celebrale ed è composto da punta dell'ago circolare con diversi fori per succhiare e presenta i vantaggi della piccola ferita, meno complicazioni, di grande diametro, con fori per più suzione, piccolo fondo cieco e rapida velocità di suzione maggi veloce ed, inoltre, può essere fissato in cervello, per evitare punture ripetute e diminuire il danno al tessuto cerebrale. In industrial and above all medical applications, the system or body is made up of components from components or organs that may require the insertion or extraction of materials or substances with precision and in compliance with quantities and locations through the penetration of needles as in the medical case, for example, in which it is often necessary to extract substances or insert medicines in particular organs and in particular positions. The state of the art closest to the proposed solution is represented by the patent CN1056818 "Puncture probe with multi-porous bulb-headed catheter" which describes the suction of cerebral hemorrhage with a medical puncture needle and is composed of a circular needle tip with different sucking holes and has the advantages of small wound, less complications, large diameter, with holes for more sucking, small blind bottom and faster sucking speed faster and, moreover, it can be fixed in the brain, to avoid repeated punctures and decrease the damage to brain tissue.
Infine, il conseguimento della riduzione significativa dell'indebolimento del muscolo cardiaco consiste nel fornire sostegno al muscolo cardiaco mediante l'impianto chirurgico iniettando con ago per ogni punto, secondo una schema prestabilito, a cuore battente una sostanza biologicamente inattiva, per evitare il rigetto, ed auto-gelificante. Finally, the achievement of the significant reduction of the weakening of the heart muscle consists in providing support to the heart muscle through surgical implantation by injecting with a needle for each point, according to a predetermined pattern, with the beating heart a biologically inactive substance, to avoid rejection. and self-gelling.
Quanto sopra detto comporta la necessità di effettuare l'operazione secondo determinati percorsi all'interno dell'organo dove per ogni percorso sono previsti più punti di penetrazione in cui effettuare l'estrazione o l'inserimento. La possibilità con un una sola penetrazione dell'ago di effettuare su uno schema definito una serie di estrazioni o inserimenti comporta la riduzione del numero di penetrazioni dell'ago con notevoli vantaggi di rapidità e precisione. What has been said above entails the need to carry out the operation according to certain paths inside the organ where for each path there are several penetration points in which to carry out the extraction or insertion. The possibility with a single penetration of the needle to carry out a series of extractions or insertions on a defined pattern entails a reduction in the number of needle penetrations with considerable advantages in terms of speed and precision.
L'obiettivo che la presente invenzione vuole raggiungere consiste in una semplice ed immediata soluzione migliorativa a basso costo al problema tecnico posto per tutte le tipologie di intervento in cui si richiedono inserzioni o estrazioni di sostanze puntuali e secondo schemi prefissati.. Con riferimento alla figura con due visuali frontale e laterale, la soluzione proposta riguarda un ago catetere costituito da un corpo centrale 1 con più fori 2 nella sua parte terminale ed alle sue estremità da una punta 3 e da una testa 4. The objective that the present invention intends to achieve consists in a simple and immediate low-cost improvement solution to the technical problem posed for all types of intervention requiring punctual insertions or extractions of substances and according to predetermined schemes. With reference to the figure with two front and side views, the proposed solution concerns a catheter needle consisting of a central body 1 with several holes 2 in its terminal part and at its ends by a tip 3 and a head 4.
Il corpo centrale 1 può essere costituito da un tubo cavo di qualsiasi materiale e spessore, di ogni sezione (circolare, ellittica, quadrata, triangolare, rettangolare, eccetera) e forma (rettilinea, curvilinea o variabile) e lungo il tubo sono realizzati fori 2 di qualsiasi forma e disposti in ogni posizione. Nella figura il corpo centrale è riportato rettilineo The central body 1 can consist of a hollow tube of any material and thickness, of any section (circular, elliptical, square, triangular, rectangular, etc.) and shape (rectilinear, curvilinear or variable) and holes 2 are made along the tube of any shape and arranged in any position. In the figure the central body is shown straight
La punta 3 ricavata su una estremità del corpo tubolare (1) può essere aperta completamente oppure chiusa da un tappo che segue l'andamento della punta oppure aperta in parte mediante una apertura sul tappo. Nella figura la punta è riportata completamente aperta. The tip 3 obtained on one end of the tubular body (1) can be completely opened or closed by a cap which follows the course of the tip or partially opened by means of an opening on the cap. In the figure, the tip is shown completely open.
La testa 4 ubicata sulla estremità) opposta a quella della punta 3 è un supporto solidale con il corpo tubolare 1 e costituisce il collegamento con il serbatoio in pressione o depressione mediante un sistema di fissaggio solido che può essere a vite, conico cavo od altro sistema equivalente. Nella figura la testa fissata al corpo tubolare è riportata conica cava. The head 4 located on the end) opposite to that of the tip 3 is a support integral with the tubular body 1 and constitutes the connection with the pressure or depression tank by means of a solid fixing system which can be screw, conical hollow or other system equivalent. In the figure the head fixed to the tubular body is shown as a hollow conical.
