Definitions
- the invention relates to a hollow needle according to the preamble of claim 1.
- hypodermic hollow needles which are made of steel and are inserted into human skin, are widely used to draw blood from veins or to inject a drug. Hypodermic needles have a very sharp tip, so that they can easily be injured when handled.
- hypodermic needles can also be used in connection with a syringe as a pull-out cannula to draw off liquid, for example a medicament, from a bottle sealed with a rubber stopper. The needle is then replaced before the patient is injected. If the first needle used is not properly disposed of, a third unsuspecting person may be injured.
- plastic spikes In order to avoid the risk of injury, plastic spikes have been developed which are pressed in by the container closure, after which liquid can be drawn out of the container using a conventional syringe. Although these plastic spikes reduce the risk of contamination when taking and preparing a medication through built-in ventilation and liquid filters and make it easier to work hygienically when taking multiple medications with a large, tightly closing flap and a contact-protected connector, handling such spikes is more cumbersome than dealing with one Syringe attached hollow needle. The production costs of such spikes are also higher than those of a hollow needle. Such spikes are not suitable for injecting a patient.
- the object of the invention is to design a hollow needle of the type specified in the introduction so that a risk of injury on the part of the user and also on the part of the patient is largely excluded.
- This is achieved according to the invention by the features of claim 1.
- the hollow needle is additionally provided with an optical marking which prevents confusion with hypodermic needles.
- the optical marking on the hollow needle itself draws the user's attention to the fact that this hollow needle can only be used for handling liquids.
- Fig. 1 shows schematically a hollow needle on a syringe and Fig. 2 shows a hollow needle with a needle holder.
- a piston 2 is displaceable.
- a needle holder 3 is attached, for example by means of a Luer cone, in which a hollow needle 4 made of steel is fastened.
- the needle tip has an inclined surface 5 so that the needle can be pushed through a rubber stopper or similar container closure.
- the outer edges of the oblique face 5 are butt-ground, rounded or otherwise defused in such a way that the needle tip looks blunt and does not injure the human skin in normal handling.
- the inclined end face 5 expediently has an angle to the longitudinal axis of the needle which is in the range from approximately 30 ° to 60 °. This further reduces the risk of injury because the tip of the needle is thereby made more blunt than is customary with hypodermic needles, the tip of which has an angle of approximately 17 °.
- an optical marking is provided on the outer circumference of the needle body itself, for example a section 6 with a certain color scheme. This optical marking 6 can extend over the entire length of the hollow needle 4 or only over a partial section.
- the optical marking which indicates that the needle tip is not sharp, can be designed in various ways, for example in the form of rings 6a on the needle body, as a longitudinal stripe on the needle or as a continuous color area that differs significantly from the metallic appearance of a standard hypodermic steel needle.
- the needle itself is provided with an optical marking and not the needle holder 3.
- the optical marking can be formed by plating or etching the steel needle 4, preferably after grinding or defusing the needle tip or its outer edges. It is also possible that the needle tip itself is defused by the plating or etching process. Here, the optical marking formed by plating or etching extends to the needle tip, as shown in FIG. 2 at 6b.
