Definitions

  • the invention relates to an injection device
  • injection needles for the continuous or periodic subcutaneous or intramuscular introduction of an aqueous or oily medicinal solution into body tissue.
  • These injection needles can be connected to a mechanical or automatic metering device by means of a hose made of material which is inferior to the medicinal solution and is compatible with trade.
  • a continuous or periodic supply of the therapeutic solution is desirable, since this is the only way to ensure a uniform active substance level in the blood.
  • an electric metering pump is usually used, which is worn on the body and which delivers the remedy via a hose line through an injection cannula fixed in the subcutaneous or muscle tissue.
  • higher concentrations of medication than required occur at the entry point in the body tissue.
  • the increased drug concentration occurring at the injection site can be local depending on the chemical nature of the drug and its concentration Symptoms of irritation and inflammation-like conditions, which in extreme cases necessitate the termination of therapy.
  • US Pat. No. 4,159,720 describes a device which brings the medicinal solution into the body from a storage container fastened to the skin through a wick made of silk or medical suture material in the tissue.
  • This method has the disadvantage that the dosage is predetermined and constant by the surface of the wick, so that no dosage adapted to the daily profile is possible.
  • the tissue compatibility of the wick material must be ensured in a special case.
  • a syringe head which is provided with 5 nozzles for receiving injection needles. However, this is provided as part of an injection syringe for wheal formation. Due to the spatial expansion and the structural details of the syringe head and the nozzle for receiving the injection syringes, this device is not suitable for being worn on the body for a long time after being fixed at the desired injection site.
  • FR-PS 11 42 769 describes an injection needle which has lateral openings so that the medicament to be injected is distributed in the tissue along the needle. Despite the distribution in depth, this can lead to undesirable concentrations at the injection site.
  • the object of the invention is to reduce the concentration of the medicinal solution at the point of entry at a constant inflow rate in the case of a continuous injection which is required for the treatment of various diseases by increasing the injection area, so as to cause the concentration of medicinal product at the point of entry to remain constant Avoid tissue irritation and inflammation.
  • the injection device enables a predetermined areal distribution of the solution to be injected.
  • the holder is in particular designed so flat that it can be easily fixed at the injection site and rests flat on the body, for example, without taking up much space.
  • the injection device can be applied in a simple manner through the parallel longitudinal axes of the cannulas.
  • a particularly simple construction is achieved in that a pipeline arrangement forming the rigid holder and feed line is provided, in which the pipe axis or the pipe axes lie in one plane and with which the cannulas, which are arranged on one side of this plane perpendicular to it, are connected are.
  • the pipeline arrangement is particularly advantageously a pipeline ring.
  • Such a pipe ring ideally fulfills the requirements of being fixable and flat on the body without taking up much space to lie on.
  • a tangential connection piece is provided for this pipe ring.
  • the cannulas are arranged at the same distance from one another.
  • the cannulas are provided with a closed cannula and several side outlet openings.
  • a handle for example, can advantageously be attached to the rigid holder carrying the cannulas.
  • B. be arranged in an arc shape.
  • Fig. 1 is a plan view of a pipe ring
  • Fig. 2 is an enlarged view of the pipe ring from below
  • Fig. 3 is a schematic, partially sectioned side view.
  • a pipe ring 2 is shown in the figures.
  • This pipe ring 2 has a tangential connection piece 1, which can be connected, for example, to a Teflon hose, to which a Luer look connection connects.
  • a plurality of cannulas 3 extend perpendicularly to the plane A-A of the pipe ring 2 and are connected to this pipe ring.
  • the axes of the cannulas 3 run parallel to one another.
  • the cylindrical hollow body is an annular tube with an outer diameter of 20 mm.
  • the inside pipe diameter is 1 mm, the outside pipe diameter is 1.5 mm.
  • 4 injection cannulas with a clear width of 0.2 mm and an outer diameter of 0.45 mm are attached parallel and at the same distance to each other.
  • the ring-shaped pipe also has a straight connecting pipe 16 mm long tangentially and parallel to the ring plane with the same pipe cross-section as the ring-shaped pipe.
  • the handling of the injection needle according to the invention is as follows: The entire system (dosing device, supply hose and injection device) is filled with the light medium solution without bubbles and the syringe is inserted into the body tissue at the desired location so that the ring-shaped tube lies on the skin. The injection device is now attached to the body by a physiologically compatible plaster or the like and the metering device is put into operation.

Abstract

Un dispositif d'injection permet de distribuer sur une large surface la substance à injecter. En même temps, il se fixe aisément sur le site de l'injection et occupe peu de place, posé à plat sur le corps. Un support rigide porte plusieurs canules (3) mutuellement espacées reliées à un conduit d'alimentation et ayant des axes longitudinaux parallèles.
