hH, calculating the penetration depth of the
steel needle 21 into the skin, namely the actual injection depth, wherein the intelligent terminal stores a relational database of the obesity index and the theoretical injection depth, the intelligent terminal compares the actual injection depth with the theoretical injection depth after injection is finished, and judges the injection effect to be four grades of excellent, good, medium and poor, wherein the error between the actual injection depth and the theoretical injection depth is excellent when the error is +/-1 mm, the error is good when the error is +/-2 mm, the error is more than +/-2 mm, and the steel needle is not penetratedPoor at skin time;
the debugging of the regression model when leaving the factory is completed through the needle inserting test of the insulin intelligent injection devices, the intelligent terminal judges the injection effect of each needle inserting, when the injection effect is judged to be poor, the intelligent terminal reminds the user to restart the needle inserting, the injection force output is adjusted through the least square method, the intelligent terminal stores the needle inserting data of each time, and the initial regression model is continuously perfected to enable the insulin intelligent injection devices to be more suitable for each user.
The step (IV) is specifically as follows: when the injection is finished, the upper surface of thepush plate 12 contacts the twopressure sensors 15, and when thepressure sensors 15 bear pressure, the intelligentterminal control alarm 7 gives an alarm to remind a worker to remove the intelligent insulin injection device, draw out thesoft needle 22 from the skin, and finish the injection.
The above embodiments are merely to illustrate rather than to limit the technical solutions of the present invention, and although the present invention has been described in detail with reference to the above embodiments, those of ordinary skill in the art should understand that; modifications and equivalents may be made thereto without departing from the spirit and scope of the invention and it is intended to cover in the claims the invention as defined in the appended claims.
