Definitions

  • the subject of the present invention is a portable or non-portable injection regulator, the main application of which could be the medical syringe, characterized in that it allows its user to inject at an extremely regular rate while eliminating the effort. manual required to advance the piston.
  • this injection regulator of a universal nature allows, between certain limits, to preselect the time of the operation for the chosen volume of liquid to be injected, the syringe can only be partially used.
  • Fig 1 is a general plan view.
  • Fig 2 from above representing the injection regulator mounted on a large traditional portable syringe ready for use, the part reserved for the support of the thumb is flat and circular.
  • Fig 2 in the middle represents as in Fig 2 from the top the same syringe of the same type but of smaller volume.
  • Fig 2 at the bottom shows a syringe, the part reserved for the support of the thumb is a loop.
  • the injection regulator shown in the drawing includes an orifice 1 through which the latter is introduced onto the very body of the syringe at the height and under the projecting part of the latter usually intended to support the two index and middle fingers of the operating hand during the injection, the ridged jaw 2 having been previously and symmetrically spread under the effect of the manual pressure exerted on the buttons 3 and k - the fixing of the injection regulator to the syringe then being ensured by reclosing automatic of the jaw under the effect of a return spring.
  • the injection regulator in place on the syringe, the udder of which turns out to be at the bottom of its reservoir in front and in the direction of the needle and after having pressed the button 5 .
  • the support pu ca ca usually replacing the thumb and attach to the son 13 and l themselves wound and connected by their other ends to the cylindrical barrel lo, will be pulled against the force of the spring 11 and placed axially capped on the circular plate or the loop of the syringe.
  • the user will proceed as usual to fill all or part of the tank with his ringing ring and then push the button 23, the effect of which is to restore the gear of the exhaust pinion 8 with the barrel lo ce the latter being blocked by its pawl 9.
  • the programmed syringe containing its injectable liquid is locked ready for use and can therefore be waiting for the injection operation without anything can happen.
