Description
Technical field
The utility model belongs to the field of medical instrument technology, and in particular to a kind of insulin injection pen.
Background technique
Diabetes are a kind of metabolic disease due to caused by defect of insulin secretion or insulin action obstacle, main table
Existing form is hyperglycemia.And persistent high blood sugar can lead to body tissue's organ, especially eye, kidney, angiocarpy and nervous system by
To damage, lead to dysfunction and failure.
Currently, the conventional method for the treatment of diabetes is insulin injection, and the injection of insulin is infused using pin type
Emitter, but using not only pain is significant when needle injector injection, enable most of patients (especially children) generation psychology frightened, it is long
Phase injects the damage that also will cause subcutaneous tissue, nerve and capilary.
In order to solve needle injector insulin injection generation the above problem, occur needleless injector in the market,
Using high-pressure jet principle, medical fluid is made to form thinner liquid flow, moment penetrates skin and reaches subcutaneously.Not using needleless injector
The above problem is addressed only, and onset time is faster, drug absorption rate is higher.
In the prior art, needleless injector mainly utilizes electromagnet mostly using the structure of electromagnetic drive type
Thrust that iron core generates and kinetic energy drive, as Chinese invention patent application CN101455868A disclose a kind of electromagnetic type without
Needle injection, including shell and handle are equipped with percussion coil and backhaul coil in shell, fire coil and backhaul coil is located at
It on coil brace, fires and is equipped with cage ring between coil and backhaul coil, fire between coil and backhaul coil and coil brace
Equipped with magnetizer, it is equipped with striker in coil brace, internal thread is equipped in housing outlets, is equipped with electronic circuit in handle, on handle
Equipped with switch.Medical fluid is extracted into ampoule when use, then ampoule is attached on the internal thread in housing outlets, then by ampoule
The position injected needed for injection orifice alignment, pressing switch can be completed one injection.Its working principle is that being sent into percussion coil
Pulse voltage after adjusted, coil obtain electric generation magnetic field, push striker to impact forward, medical fluid is projected；Then by pulse electricity
Force feed enters backhaul coil, and coil obtains electric generation magnetic field and striker is sucked back original position, can press instruction works in cycles in this way.
However, there are the following problems for above-mentioned electromagnetic needleless injector: (1) due to being equipped with percussion coil and backhaul in body
Coil, structure is more complicated, and volume is big, higher cost；(2) striker that is, impact armature be fixed to the impact force of ampoule piston
, i.e., it cannot change the injection pressure of medical fluid, cannot also adapt to the biggish injection of skin strength difference, such as adult and children.
Utility model content
The utility model is intended to provide a kind of insulin injection pen, cannot change pancreas islet to solve existing needleless injector
The problem of injection pressure of plain medical fluid.
To solve the above-mentioned problems, the utility model provides a kind of following scheme: insulin injection pen, including hollow pipe
