Definitions
- the invention relates to a method for stimulating a tissue and a device therefor.
- CSII Continuous subcutaneous insulin infusion
- pump therapy is currently the most effective insulin therapy for the treatment of insulin-dependent diabetes.
- the insulin is not injected in individual doses, but passed through a small programmable pump in the body.
- the pump is permanently on the body, but not in the body, with insulin being delivered via a cannulated cannula following a programmed schedule.
- Insulin catheters come in different lengths with different needle sizes and materials.
- the administration of insulin is based on the following principle: There is a basal supply of insulin, which is delivered by the pump and which covers the non-food-dependent insulin needs and several so-called BoIi, so dosed insulin individual distributions, which can be used during meals and for value correction , Usually, only one insulin type is present in these pumps, either normal insulin or insulin analogs.
- An insulin pump delivers fast-acting insulin in short, even intervals to achieve a uniform effect. You can program the basal rate per hour in the pumps. Pump therapy has therefore become a routine therapy today.
- a small motor in the insulin pump forces insulin out of a reservoir in the pump via a catheter into the subcutaneous fatty tissue, usually the abdominal region. The pump speed of the motor and thus the amount of insulin per unit time can be programmed according to the needs of the patient.
- an insulin bolus is to be distributed in addition to the insulin basal rate, the user can himself actively call up insulin to lower elevated blood sugar and / or to recall insulin for a carbohydrate-containing meal.
- the motor of the pump then delivers additional insulin through the catheter into the subcutaneous fat tissue.
- Such catheters have a plastic tube and a cannula which extends through the skin into the subcutaneous fatty tissue.
- the cannulas are for example made of steel or plastic, for example Teflon.
- the catheters also have a body on the cannula, which is attached by means of a patch or a self-adhesive pad on the skin.
- insulin therapy catheters may remain in one location for three days before a new catheter is inserted elsewhere.
- the absorption kinetics of insulin in the body depends on various factors, some of which can be directly influenced by the diabetic. It is known, for example, that a massage of the injection site leads to an accelerated kinetics.
- This effect is used by some diabetics to deliver BoIi to ensure a shorter injection-to-meal interval, or to reduce hyperglycemia as quickly as possible to the euglycemic area.
- the object of the invention is to provide a method and a device for stimulating a tissue, with which the absorption kinetics is improved.
- the object is achieved by a method having the features of claim 1 and an apparatus having the features of claim 8.
- the range of administration is stimulated to increased circulation, whereby the vessels or capillaries present in the tissue are stimulated to increase or improve blood circulation.
- the absorption can be increased since the insulin is released from the subcutaneous fatty tissue from the interstitial fluid into the blood vessels.
- the method can be realized in different ways.
- the site of insulin infusion under which the insulin depot is located in the subcutaneous area is mechanically stimulated. With the mechanical stimulation, a manual massage is modeled.
- vibration device on the catheter or on the catheter hub, which acts on the skin around the puncture site.
- vibration devices can be based, for example, on the piezo principle known per se or implement vibration devices which are also realized in mobile phone batteries.
- an electric motor which moves an eccentric weight is used as the vibration transmitter.
- the vibrations can be carried out vertically or horizontally to the skin surface.
- a mechanical vibration device is also supplied with electrical energy from the infusion pump, so that a supply line is laid parallel to the catheter tube.
- the catheter tube and the electrical supply line can be connected to one another or even formed integrally with one another. This is particularly advantageous if the catheter is not replaced frequently.
- the mechanical vibrator and catheter With means for releasable attachment.
- Such means are, for example, a bayonet closure, wherein the vibration device, for example, the catheter or a base body which carries the channels, surrounds and is placed on this prior to insertion of the catheter and locked, for example by turning.
- the vibration device for example, the catheter or a base body which carries the channels
- the vibration device surrounds and is placed on this prior to insertion of the catheter and locked, for example by turning.
- it is advantageous that a repeated use is possible, in particular in vibration devices that have a driven eccentric, which is justified in view of the higher manufacturing costs.
- the catheter is preferably formed so that the device is glued plate-like with a self-adhesive tape on the skin and the plate simultaneously forms or carries the catheter hub.
- heating elements such as heating wires are present, which are also preferably supplied by the pump with electrical energy.
- both a releasably lockable and a one-piece or monolithic training with the catheter is possible. While a vibration device does not have to be in direct contact with the skin, but the vibration can be entered into the puncture site via the catheter itself, in a device in which heat is applied, the device is placed directly on the skin around the puncture site.
- electrodes act on the skin adjacent to the puncture site, which transmit weak stimulus currents into the skin and thus lead to a stimulation of the skin surface.
- a corresponding device is also, for example, placed in a ring around the actual catheter and fastened in one piece or detachably, wherein the power supply also takes place here via the pump, a separate module or power supply integrated in the device, for example by means of rechargeable battery or button cells.
- stimulation current electrodes can be introduced via appropriate means ultrasound, which acts on the tissue.
- a device can also have a radiation device which introduces infrared rays, that is to say heat rays, into the tissue. This can be done for example via suitable LED, which are arranged, for example, annular.

- such a device 1, which is circular disk-shaped with a central recess 19 may be formed as a vibrating device 1 or as a device 1, which acts on an underlying tissue via heat, ultrasound, infrared rays or the like.
- the device 1 is not limited to a mechanism of action, the action mechanisms can also be combined with each other, so that vibration and / or ultrasound and / or heat and / or other radiation and / or chemical substances are introduced.
- FIGs. 1 shows the uptake of insulin into the blood, where the dashed line marked S indicates the insulin titer in the venous blood, while the dotted field labeled N shows the normal course without stimulation.
- the blood sugar content is indicated, wherein the dotted field described by N shows the degradation of the blood sugar content in the venous blood without stimulation, and the dashed line indicated by S shows the blood sugar degradation in the blood when the insulin by means of stimulation of the tissue is introduced.
- Figs. 1 and 2 illustrate the advantages of the invention, because an insulin bolus is much faster and more effective.
- the hyperemia achieved by various devices generally increased blood flow or blood volume of an organ or circulation section
- pharmacokinetics temporary course of the drug concentration in the
- Organism and subsequently to a more rapid pharmacodynamics (pharmacological action of the drug, for example in the case of insulin, the more rapid decrease in blood glucose).
- pharmacodynamics pharmacological action of the drug, for example in the case of insulin, the more rapid decrease in blood glucose.
- the invention can also be used for the administration of all subcutaneously applied (infused) and thus subcutaneously absorbed or resorbed from the subcutis substances (hormones, analgesics, anticoagulants, growth factors, interferons, etc.).
