DE102008016987A1 - Insulin syringe i.e. injection pen, for injection of insulin in fatty tissue of diabetic, has closing cap fitted on mechanical part after utilization of syringe such that marking arrows mark and store time of last injection of insulin - Google Patents

Abstract

The syringe has a closing cap (7), which is removed for utilization of the syringe and is fitted after utilization of the syringe. A mechanical part (1) is provided with a marking arrow and a closing cap is provided with another marking arrow with additional day time indicator. The closing cap is fitted on the mechanical part after utilization of the syringe such that the marking arrows mark and store the time of last injection of the insulin. The mechanical part is provided with a ring and a tappet.

Description

The Invention relates to a Injektionspen as he z. B. for injection of insulin is used in the fatty tissue, which is equipped with a memory function is. This memory function is achieved by using the pen with a scale is provided on the z. B. the last injection in time or can be labeled quantitatively.

State of the art

injection pens consist of a mechanical part in which the technique and the liquid ampoule and the injection needles are housed, and a shutter, which is removed for use and put back on after use is used to protect the delicate parts. The flap can be postponed arbitrarily and is replaced by a resistor held. The disadvantage here is that there is no indication of performing the Spraying process gives. Because the spraying in most cases of Long-term sick as diabetics is carried out, it is a routine process, which often receives little attention. So it can often happen that the diabetic After some time, he asks himself if he has actually injected.

It elaborate instrument clusters were developed, their electronics indicated the time after the last injection. So fast be determined whether the last injection is timely. These devices are but again disappeared from the market, as they are sensitive and expensive were.

task

The The present invention aims to provide a pen with a very simple Memory function to develop by the time of the last Injection can be established beyond doubt.

Based the attached Drawings to illustrate the invention to be discribed.

embodiment

It demonstrate

1 a normal injection pen

2a to 2d the different positions of the pen according to the invention

3 the collapsible rings

4 the handling of the assembled rings

5 the cap with additional marking wheel

6 the cap for sleeve intake

1 shows as an example a normal Injektionspen, from the mechanical part 1 and the cap 7 which is deducted for use. The mechanics part 1 includes all necessary parts for use such as dosing button 2 , Dosing indicator 3 and ampoule housing 4 , The dosing button 2 is rotated until in the dosing display 3 the correct dose is displayed. Leg injection process reaches z. B. the insulin from the ampoule 5 over the syringe 6 in the target area by the dosing button 2 is pressed down. After use, the cap is 6 postponed again. With the holder bracket 8th The pen can then be stowed like a fountain pen in a jacket pocket.

2a to 2d show the inventive design of the same pen, but with a scale over which the time of the last injection can be set and stored. This is the cap 7 in this case marked with relevant times of day on the circumference. At the cap 7 is an arrow at any time of the day 10 angebraucht. The mechanics part 1 is with an arrow 10.2 , fitted. After an injection are the mechanics part 1 and the cap 7 stuck together so that the arrow 10.2 of the mechanical part 1 on the arrow 10.1 showing the time of injection.

To avoid mistakes during assembly and to prevent twisting of the parts is in the area of the merger in the cap 7 a ring 13 with notches 14 appropriate. The number of notches corresponds to the number of arrows 10.1 on the cap 7 , 3 , The mechanics part 1 is also with a ring 15 fitted. This ring is with a cam 16 provided when pushing the cap 7 and the mechanics part 1 at the point with the arrow 10.1 the cap 7 must match, which represents the relevant time of day. Since both parts of the parts are held together by a resistor, the injection time is clearly stored.

4 shows the development of the rings 14 and 16 at the point where both parts of the piece are joined together. Because the notches 14 and the cam 16 are tight tolerances, when assembling the two parts of the parts 1 and 7 be very carefully noted that the parts are pushed together in the right place. As a result, an error due to careless assembly is almost impossible. score 14 and cams 16 also prevent an unbe intentional twisting.

5 shows a cap 7 that with a knob 14 with arrow 19 Is provided. On the cap 7 there is a scale 13 with numbers of z. B. 1-24, which are arranged at the periphery. The knob 14 can be incrementally incremented by one tick mark each time and can be used to save the last insulin amount applied by turning the arrow to the corresponding number.

6 shows a cap 19 with a sleeve pickup 20 is provided, on which the sleeve 21 can be pushed and fastened. This makes it possible to swap out sleeves with different information quickly and cheaply.

Next the scaling of times of day and insulin quantities described here can of course, too other classifications such as daylight hours or days of the week, etc. applied become.

As well can also other instruments where a part is removed for use is and is freely rotatably replaced, modified according to the invention become.
