Description

Insulin pen-cartridge injection pen

Affiliated technical field

This utility model relates to a kind of insulin pen-cartridge injection pen that can automatically complete action of injection, automatic control power set are especially housed, adopt single-chip microcomputer and micro machine, set after injected dose, can automatically complete inserting needle, automatically push away medicine, pin is pulled out in automatic subcutaneous stop for 6 seconds afterwards automatically.Eliminate the feared state of mind of patient to injection, during use, patient does not need to learn anyly to comprise inserting needle strength, inserting needle speed, thrusts angle, pushes away efficacy of a drug amount, keeps stable, varied angle is not pulled out pin etc. injection technique, without others, help, can oneself be injected at easily and safely the diverse location of health.

Technical background

At present, the medicine insulin that maintains that diabetics is used is all the year round made disposable pen core mostly, comprises medicine bottle, syringe needle and enters medicine piston, uses special-purpose pen core syringe, and the overwhelming majority is injected by patient oneself.Existing insulin pen core injection syringe is still traditional inserting needle injection system, tradition injection needs inserting needle rapid, stable, any small rocking after syringe needle thrusts, capital makes patient increase pain, needs of patients is for a long time familiar with, is grasped, and a lot of people are thrust human body, pushed away the medicine frightened mental burden that forms of psychology of having had an injection syringe needle.Health is applicable to the limited several positions of only having of insulin injection.When patient injects at oneself, only have abdominal part fortunately to operate, but when abdomen injection, need, by the mode of adjusting syringe needle angle, to control syringe needle and thrust the subcutaneous degree of depth.Especially be subject to the restriction of syringe itself and arm length, stretching, extension angle and people's range of vision, patient oneself can not be injected at the pork rump position that HUANTIAO acupoint is following, pain threshold is minimum.Every day 2 times to 4 times, in the injection of same position, can cause the series of problems such as this position is livid purple, sclerosis all the year round.Because diabetics majority is not that medical operation, age distribution are wide, middle-older patient is many, nourishes the fear of having an injection, and the overwhelming majority, especially female patient need by others, help through injection twice every day, have increased physiology, psychology and living burden.

Summary of the invention

In order thoroughly to have eliminated the psychology fear that patient has an injection to tradition, overcome the insulin pen-cartridge injection pen of existing structure, needs of patients study adapts to, bad oneself injection, oneself can not be injected at pork rump position, most of patients needs others to help the deficiency of injection, this utility model provides a kind of all insulin pen-cartridge injection pens of action of injection process that automatically complete, can conveniently control depth of needle, any position can guarantee the vertical of inserting needle, rapidly, stable, patient oneself can grasp easily, be injected at security and stability any suitable position of health, particularly inject the fundamental difference of inserting needle mode and traditional inserting needle mode: set after injected dose, injection pen is attached to injection site, injection pen can complete inserting needle automatically, automatically push away medicine, then subcutaneous stop pulls out whole actions of pin for 6 seconds automatically, amateur medical patient, without learning injection technology, thoroughly change the psychological burden of traditional insulin injection.

This utility model solves the technical scheme that its technical problem adopts: in can packing the injection pen slide mechanism assembly of finished product medicament (pen core) into, there is adjustable per injection dose control handle, gear clutch, push away medicine turbine, push away medicine screw mandrel, push away medicine screw, push away medicine drive motors, stall plug and the fixedly claw of insulin pen-cartridge, injection pen slide mechanism assembly can be driven and be slided up and down by micromachine in injection pen main body, in injection pen main body, there is advance and retreat pin motor, control chip circuit board, battery, on and off switch, air-discharging/the move back bar switch of changing dressings, injection pen is transported trigger switch automatically, injection pen triggers tongue piece and injection pen right cover, in injection pen right cover, there is the anti-jump link stopper of clutch, the injection pen of using different-thickness instead triggers tongue piece, can use 8 millimeters and 6 millimeters of special-purpose needle heads.

During use, install battery, open injection pen right cover, install finished product insulin pen-cartridge, install syringe needle, the injection pen of finishing changing corresponding thickness according to the needle length of using triggers tongue piece, turns on the power switch, and first rotates dose control handle, adjust injection dose, buckle injection pen right cover, aim at injection site by tight, injection pen started inserting needle automatically, push away medicine, push away after medicine and stopped for 6 seconds, automatically pull out pin and all move.

Patient needn't learn, practise all problems of the tradition injections such as the dynamics, speed, angle of inserting needle, as long as injection pen is pinned, is adjacent in injection site, just can guarantee the vertical, rapid, stable of any position inserting needle, the pork rump position that cannot see in vision also can oneself easily complete injection.No longer need to be grasped needle angle and control absolute depth.During injection, as long as being adjacent to injection site, injection pen keeps not having relative motion, even if there be slight rocking, also can guarantee to thrust the variation that subcutaneous syringe needle and injection site do not have position and angle, eliminated traditional syringe because of the fixed pain that patient is increased of having light fingers.Because injection pen completes the overall process of insulin injection completely automatically, can thoroughly eliminate the psychology fear that patient has an injection to tradition, reach patient and need not learn for a long time just energy oneself injection of exercise, do not need others to help injection, can facilitate, be injected at security and stability the object of any correct position of health.

This utility model beneficial effect is, when injection pen can complete injection automatically, inserting needle, the whole actions that push away medicine, stopped for 6 seconds and pull out pin, use very simply, patient does not need study, exercise, own just can grasp easily, in any suitable position of health, oneself complete injection with security and stability, avoid injecting same position throughout the year, palliate the agonizing sufferings, eliminate the psychology fear that patient has an injection to tradition, reduced family members' burden.
