Embodiment Construction

[0021] figure 1Shows how blood flow changes over time in the area around a soft catheter inserted into the body for expelling medication. As shown, subcutaneous adipose tissue blood flow (ATBF) increased approximately 40% after two days. Immediately after the catheter has been inserted, ATBF has an exponential mean of approximately 2.1. After having been catheterized for 48 hours, the ATBF index value was 2.9, a difference corresponding to a 38% increase in ATBF. Also shown is the interval around the mean ATBF value corresponding to the 95% statistical confidence level.

[0022] The medical device of the present invention is equipped with a timer for recording the time the catheter is inserted in the body. This information is transmitted to the control unit of the medical device, which is also programmed with a decision support software algorithm that is used when calculating compensatory actions related to the time elapsed from the insertion of the catheter. The longer th...

Abstract

A medical action device is adapted to cooperate with an object to be inserted into a body and to cooperate with a timing device, able to start timing from the moment the object is inserted. This information is fed to a control unit whereby the control unit gets an input which can be used to compensate one or more parameters of the medical action as a function of the increased blood flow in the area around the inserted object over time due to the inflammation reaction.

Description

technical field [0001] The invention relates to a medical device capable of performing medical actions. The medical device may be used in combination with objects inserted into the body. The invention will adjust the medical device to compensate for one or more parameters of the medical procedure related to the time elapsed since the object was inserted into the body. Background technique [0002] In diabetes management, the main concern is to maintain a patient's blood glucose levels at acceptable, near-normal levels around the clock. Injection of one or more discrete doses of insulin daily or weekly will usually result in blood flow spikes in insulin levels, since these discrete doses will compensate for many small or large fluctuations in the patient's blood sugar levels due to meals, exercise, etc. . [0003] Fluctuations in blood glucose concentrations outside the normal range can cause acute crisis in the short term and diabetic complications such as heart disease, ...
