Description
Technical field
The present invention relates to the field of medical instrument technology, more specifically a kind of multi-functional insulin injection pen.
Background technique
The invention belongs to medical sanitary technology field.China's diabetes morbidity is high, and insulin therapy is good control blood
Sugar important means, even studies have reported that patient blood glucose's compliance rate of use of exogenous insulin also only have 37%, influence
Insulin therapy effect three elements are insulin, injection of insulin technology and insulin injection device.The investigation result display whole world
Injection phenomenon lack of standardization is generally existing, and China injection status more allow of no optimist, comprising: injection before do not carry out insulin title and
Dosage form is checked, and needle head for injection pen is reused, and does not stop after injection or residence time inadequate 10s pulls out needle etc..
Insulin special pens used in China include the special pens of disposable special pens, replaceable medicine core at present.But
For the insulin special pens of medicine core replaceable in insulin injection device, although generally using on the market and clinically,
But still there are many deficiencies, shows according to investigations, the factor for influencing injection of insulin specification wherein just includes insulin special pens sheet
The shortcomings that body, is caused, since insulin medicine title and dosage form are more, when patient needs to carry out two kinds of insulin hybrid injections,
Traditional novopen can not be completed once, need to complete the note of two kinds of different names and dosage form by the replacement of pen core
It penetrates, or prepares multiple injection pens, but the latter is at high cost；Secondly, the case where there is also patient confusion's uses, especially for old
Year patient or dysphotia patient or lack of knowledge patient are easy to appear before the meal and sleep proinsulin and obscure use.Cause pancreas
Island element fails the effect brought into normal play, and wastes medicament, and there are some potential safety problemss.
For specification injection of insulin, guarantees that patient blood glucose can effectively control, reduce bring due to injection of insulin
Complication, because of a kind of multi-functional insulin special pens of the invention, this advantages of be to can be improved the drug safety of patient,
Injection of insulin specification rate is improved, patient blood glucose's compliance rate is improved.
Summary of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of multi-functional insulin injection pen, the present invention
According to diverse designs two of insulin title and dosage form for installing the fixation hole of pen core, we can for same pen
