Embodiment Construction

[0026] figure 1 A needle holder 1 is shown in which a needle 2 is fixed. Arranged on the shaft of the needle 2 is a protective element 3 in the form of a spring clip with crossed arms. Numeral 4 designates a sleeve which, together with the protective element 3, can move along the shaft of the needle. In the exemplary embodiment shown, according to the Epidural-Nadel or Huber-Nadel needle, the tip 5 of the needle is designed with a bend so that its diameter is smaller than that of the needle The sleeve 4 of the bend at the tip is then unable to move past the tip of the needle, by means of which sleeve 4 the protective element 3 cannot also pass through the needle tip.

[0027] Between the needle holder 1 and the protective element 3 is arranged a gripping part 6, the proximal end of which has a hollow cylindrical part 7 on which protruding baffles 8 are formed in the radial direction . On the front surface of the baffle, there is a cylindrical portion 9 whose distal end is ...

Abstract

Injection or infusion needle has a handle (6) for sliding or holding the protector (3) between the protector (3) and needle holder (1)

Description

technical field [0001] The invention relates to a protection device for injection needles or transfusion needles. Background technique [0002] A protective device of this type is disclosed, for example, in US 4 929 241, wherein a relatively small protective element is arranged on the needle, which is movable from a retracted position to rest on the needle tip by means of a spring. The protected position, wherein the elastic arm of the protective element covers the needle tip, and at the same time, an engagement device on the protective element holds the protective element on the needle body. Due to the small size of the protective element, it is difficult to move it over the needle by hand. Furthermore, since the clamping spring can only be released when the needle tip is exposed, the risk of injury cannot be ruled out. Contents of the invention [0003] The object of the present invention is to devise a protective device of the above-mentioned type, which is designed s...
