Definitions

  • the invention relates to a needle protection device for the needle of a syringe for taking blood, an injection syringe or the like, which has a syringe cylinder equipped at one end with the needle to receive the blood to be drawn off or containing a spray liquid, in which a manually operated piston can be axially displaced is led.
  • Blood sampling is associated with the risk of all persons involved injuring themselves after or during the withdrawal or while handling the blood collection set at the tip of the needle and possibly infecting it.
  • a pregnant woman is infected with hepatitis or HIV, is usually not known at the time of birth. Basically, all body fluids should therefore be treated as if the patient is infectious.
  • the invention has for its object to develop a cheaper solution that offers comprehensive protection during syringe handling. Starting from the needle protection device described at the outset, this object is achieved according to the invention by the following features:
  • the needle protection device is designed as a component which can be retrofitted for commercially available syringes in the form of a clip slide, which can be clipped onto the side of the syringe barrel for protective covering of the needle and can be axially displaced from its protective position covering the needle into a working position releasing the needle for puncture ;
  • the clip slide has a hollow, in the clipped-on protective position surrounding the needle conical end portion, which for a lateral insertion of the needle when placing the needle guard with a longitudinal slot and in its cone tip with a
  • the cone-shaped end section is followed by a partially cylindrical clip part which has an inner partially cylindrical contact and sliding surface for the syringe cylinder and spring-elastic expandable brackets which partially grip the syringe cylinder when the clip slide is clipped on and represent guide elements in the axial displacement of the clip slide on the syringe cylinder ;
  • the clip slide at its end opposite the conical end section has a manually actuable wheel drive which can be rotated manually about a wheel axis lying transversely to the longitudinal axis and, when the clip slide is clipped on, with frictional engagement on the
  • the barrel of the syringe barrel is in contact.
  • the needle protection device according to the invention is therefore suitable both for the withdrawal and for the injection of a liquid.
  • the syringe can be placed in protected mode without the needle becoming non-sterile.
  • the user is protected against accidental puncture injury during the handling of the syringe or third parties after removal or injection from a potentially infectious patient from contact with harmful liquid. It is even possible to manufacture the portion of the clip pusher surrounding the needle from a material that provides radiation protection if the syringe can be handled in conjunction with radioactive material.
  • the needle protection device according to the invention is not tied to a very specific syringe assembly. The majority of the cases occurring in practice can be covered with only two to three different sizes of needle protection device (based on the diameter and / or length of the syringe to be used).
  • the concept according to the invention offers a universal, but nevertheless inexpensive needle protection device which can be used in a simple manner in normal removal and injection systems.
  • the wheel drive comprises two wheels which are arranged on the wheel axis with an axial spacing from one another and which preferably each have a plastic casing. This not only enables the clip slide to be moved continuously back and forth, but also to lock it in any position, caused by the adhesion of the wheel cover mentioned on the cylinder surface.

  • the clip slide 7 is then fixed on the syringe barrel 2 by laterally pressing the two parts against one another, which leads to a spreading of the spring-elastic pairs of clips 1 3 of the clip slide 7, which can thus be clipped onto the syringe barrel 2, as a result of which the wheels 16 or their plastic -Sheath 1 7 come to rest on the outer surface of the syringe barrel 2.
  • the clip slide 7 can be moved in the longitudinal direction into a working position by manually turning the wheels 16 on the syringe barrel 2.
  • the needle 4 passes through the passage opening 10 of the conical end section 8 into a position which releases a puncture.
  • This axial displacement of the needle protection device can be carried out by the person operating the syringe 1 with one hand, with the hand operating the piston 5 of the syringe 1 at the same time.

Abstract

L'invention concerne un dispositif de protection d'aiguille qui se présente sous la forme d'un élément coulissant clipsable (7) s'adaptant aux seringues (1) disponibles dans le commerce. Cet élément peut être clipsé latéralement sur le cylindre (2) de la seringue de façon à recouvrir l'aiguille (4) et la protéger. On peut ensuite le faire coulisser axialement sur le cylindre (2) pour le faire passer de la position de protection dans laquelle il recouvre l'aiguille (4) à une position de travail dans laquelle l'aiguille (4) est dégagée pour pouvoir être utilisée. Cet élément coulissant clipsable (7) comporte une section d'extrémité (8) creuse de forme conique qui entoure l'aiguille (4) lorsque ledit élément est clipsé sur le cylindre dans la position de protection. Ladite section d'extrémité (8) présente une fente longitudinale (9) par laquelle l'aiguille (4) peut être insérée latéralement lors de la mise en place du dispositif de protection ; elle comporte par ailleurs au niveau de sa pointe une ouverture (10) par laquelle l'aiguille (4) peut passer. L'élément coulissant clipsable (7) présente, à son extrémité opposée à la section d'extrémité (8) de forme conique, un entraînement à roues (15, 16, 17) qui peut être actionné manuellement pour déplacer axialement ledit élément.
