The present invention relates to a key for a medical device, e.g. an infusion pump or a blood glucose meter preferred for discrete or continuous blood glucose determination, in particular a key for a battery compartment or other openable compartment or reservoir with an additional element, e.g. an optical Nergrösserungselement. In particular, the invention relates to a e.g. made of plastic key, with which a lockable compartment or reservoir, such as a battery compartment of an infusion pump, such. the applicant's mini-TROΝ, H-TROΝ or D-TROΝplus, a blood glucose monitor, a blood glucose sensor or a blood glucose meter can be opened and closed again.

In general, medical devices, e.g. Infusion pumps a battery compartment for batteries to power the controller and the electric motor contained in the infusion pump. This battery compartment should be protected against accidental and unintentional opening. Usually, the closure of the battery compartment is an element which can be turned out of or unscrewed from the hifusion pump and which has one or more recesses, e.g. in the form of a slot or blind hole pair, in which e.g. a coin or a special key can be used to secure the conclusion, e.g. use the coin to unscrew or unscrew to open the battery compartment. Such a special key is often not available in everyday situations.

It is an object of the present invention to propose a key for a battery compartment which is adapted to be easily carried by a user and makes it easier for a user of an infusion pump to handle the infusion pump and to carry out therapy with the infusion pump.

This object is achieved by a key according to claim 1. Advantageous embodiments emerge from the subclaims.

The inventive key for a medical device, such as e.g. for a battery compartment or reservoir of an infusion pump or a blood glucose monitor, a blood glucose sensor or a blood glucose meter has according to the invention at least one additional element, for example an optical Nergrösserungselement, such. a magnifying glass, a lens or a Fresnel lens. Furthermore, instead of a lens or also in combination with the lens, one, two or more of the additional elements described below can be combined with the key, e.g. be integrated into the key or connected to the key.

The integration of a magnifying glass into a key for a battery compartment is particularly advantageous for users who suffer from visual problems, since the detection of the locking mechanism of the battery compartment and in particular the finding of the recess for inserting the key, as well as the inspection of e.g. Sealing elements is facilitated. Furthermore, with a magnifying glass, e.g. the display of the device is enlarged and therefore easier to read.

The key according to the invention may, in a simple embodiment, be e.g. a flat cross-sectionally approximately rectangular element with a curve formed on the front edge for insertion into the slot of the closure element, wherein at the front edge in the insertion direction of the key, e.g. an annular element e.g. may be provided with a recess in the interior of the ring, which e.g. can be inserted into a correspondingly formed counter-structure in the slot of the closure element in order to position the key correctly in the closure element, e.g. to center and prefers to fix.

As an additional element, a measuring device, such as a vernier caliper, be provided, which can be inserted in only partially filled with liquid medication ampoules to determine the stopper position or the current level of the ampoule. To the For example, calipers may be provided with a scaling or a label on which the user can read what quantity, eg volume and / or amount of active substance, is still present in the ampoule. This read amount of the substance can then be entered by the user in the infusion pump, which can then advance the threaded rod so far that it rests against the stopper of the used and only partially emptied ampoule and the infusion pump thus for the precisely metered delivery of in the ampoule containing substance is prepared.

According to one embodiment, the additional element is a cleaning device, such as e.g. a cleaning brush or a cleaning pad, which is used to clean the medical device, e.g. the battery or ampoule compartment of an infusion pump can be used.

The additional element may also be a gripping tool, such as a pair of pliers, a clamp or tweezers, to which e.g. Foreign body or parts of the medical device, such as an ampoule stopper can be removed from the ampoule compartment or the battery compartment.

The attachment may be a reflective element or mirror, for example detachably attached to the medical device, and preferably attached to a pole, to allow a user to manipulate the cartridge or battery compartment or other components of the device, e.g. To inspect seals.

Likewise, the additive element may be a light-generating element, such as e.g. a light bulb or one or more LEDs, so that the inventive key can also be used as a flashlight. The light-generating element (s) may also be provided in the vicinity of the magnifying glass in order also to enable recognition of writing or components of the infusion pump in low-light or dark conditions.

The additional element can be a receiving element, in particular a compartment or a reservoir, in which, for example, glucose, a pen needle, a needle for a lancing device for Blood glucose monitoring, medication such as pills for emergency situations, an emergency reserve insulin, a blood glucose or urine gauges, an adapter or a battery lid for the infusion pump or a combination of these items can be stored and transported.

Furthermore, the additional element may be a storage medium, in particular an optical or electronic storage medium, such as e.g. a hologram, a MultiMediaCard or a MemoryStick on which e.g. a visual instruction manual for the infusion pump or configuration data, such as the e.g. hourly basal rate, the bolus increment, an alarm threshold before the ampoule is completely emptied, the volume setting, the display contrast, or doctor and patient information.

Likewise, the attachment may include a battery monitoring instrument, such as a battery monitor. a battery state-of-charge display instrument with which, e.g. the state of charge or remaining capacity of the battery or the battery can be measured or monitored.

The additional element may also be a charger or a backup battery with which e.g. the power to the medical instrument can be maintained when the batteries contained in the medical device are discharged.

Furthermore, the additional element may be a remote control with which functions of the medical device can be operated.

As an additional element, a lancet can be provided with protective cap, as required for the lancing device to carry out a blood glucose measurement.

The key may be designed such that e.g. with the use of the additional element "lancet with protective cap", it can be used as a lancing device, for example for carrying out a blood sugar measurement, thus a full lancing device and an auxiliary tool can be provided.

The attachment may be a timepiece, such as an hourglass, to allow a user a predetermined interval of time between administration of a bolus and the intake of a meal, the so-called Spritz-Ess- distance, as closely as possible.

Likewise, the attachment may be an audible and / or visual alert system to alert a user, e.g. To point out that only a small amount of insulin is contained in the ampoule of the infusion pump, or to realize a reminder function for the regular required blood sugar measurement (typ. 4-6x / day).

As an additional element, a labeling field may also be provided on which e.g. the name of the user of the medical device, an identification code of the user, an emergency call number, the health insurance number of the user or the daily time-dependent hisulin sensitivities of the user are written.

The following explanations refer to a magnifying glass as an additional element to simplify the description, however, each of the additional elements described above with the inventive key as described below.

According to one embodiment, the optical magnification element or the magnifying glass can be integrated in the key. Thereby, e.g. the key and the optical magnification element are integrally formed. For example, the key may be made of a transparent material, e.g. the part forming a magnifying glass has one or more bulges for generating the magnifying effect. The magnifying glass can e.g. be made as a high gloss element, while on the remaining part of the key an etching or erosion structure can be provided.

Furthermore, it is possible that a transparent magnifying glass can be encapsulated by a carrier as an opaque and / or non-slip or "soft" plastic part, wherein a key forming profile or plate-shaped portion of the carrier as a key z. B. may be formed with the structure described above.

The optical magnification element can be both non-detachable, as well as releasably connected to the key and be connected for example via a snap-in or snap connection with the key. In the case of the key according to the invention, a cover element for the optical magnification element is advantageously provided, which can be fixed, for example, relative to the optical magnification element and / or pivotable relative to the key and / or displaceable and preferably in one or more positions. For example, the cover can be easily clipped when it is designed as a separate or separate part. Such a cover can be pushed or folded over the optical magnification element, for example, when it is not being used to protect it from dirt or damage and can be removed from the optical magnification element, eg pushed away, folded away or clicked out to the user to allow to see through the optical magnification element.

Preferably, the battery compartment key also has a Luer-lock key, with which a Luer-lock connection can be solved. For security reasons, however, the Luer key should not be used to tighten the Luer connection.

Advantageously, the battery door key and / or the Luer lock key are pivotable and / or displaceable relative to the optical magnification element, that is to say the battery door key and / or the Luer lock key can e.g. unfolded or swung out to use one of the keys. Thereby, e.g. the battery door key and the Luer lock key as separate elements or integrally on a single element e.g. be provided at different ends, so that this element is brought into a first position when e.g. the battery door key is used and moved to a second position when the Luer lock key is used.

Preferably, between the battery key and / or the Luer lock key and the optical magnification element, a pivot or sliding connection element is provided, which can be locked or locked, so that, for example, a folded or unfolded battery key or Luer lock key can be determined in the folded or unfolded position.

A fastening element for a further key or an object or another device, such as eg a telephone, or a carrying case of the medical device can be provided on the battery compartment key in order to fasten the inventive key, for example, to other devices or objects carried by a user. Advantageously, a recording and / or playback device is provided, for example, for short messages or instructions in emergency situations, alarm and error messages, for notification of the device status or other messages, which is particularly advantageous for blind users of the key according to the invention.

Furthermore, a module for a communication extension, such as e.g. a data transmission module may be provided, which e.g. can be used for frequency conversion, data conversion or data transport from the pump to a mobile phone.

According to another embodiment, the magnifying glass is used e.g. for image acquisition of the display of the medical device and the image information, e.g. translate into language. Thus, the necessary intelligence for the coverage of special patient needs is integrated in special cases in an accessory and not in the medical device itself. The magnifying glass works here rather in the sense of a camera.
