Description

Full automatic insulin injection aid

Technical field

The present invention relates to a kind of injection assistor, particularly a kind of can with the matching used full-automatic of insulin injection pen injection assistor.

Background technology

before the present invention, use the most syringe that uses of diabetics of injection of insulin treatment to have two kinds, a kind of is insulin injection pen with syringe needle, another kind is the high pressure injector of not being with syringe needle, insulin injection pen with syringe needle makes the people that fear be arranged, during acupuncture treatment, skin is scratched in careless slightly meeting, to arm, buttocks is had an acupuncture treatment very inconvenient, old people or action inconvenient people need other people to help through, syringe needle is pricked after skin also will press injection with medicinal liquid, although high pressure injector does not have above-mentioned shortcoming, but, apparatus and consumptive material price are very expensive, loss to medicinal liquid is larger simultaneously, be difficult to accept for Most patients.

Summary of the invention

Purpose of the present invention just is to overcome the defects of insulin injection pen, and a kind of of design, development can inject assistor with the matching used full-automatic of insulin injection pen.

Technical scheme of the present invention is:

Full automatic insulin injection aid, by upper, setting of casing forms, on, cased interface is that the screw and nut rotation is fastening, injection pen is contained in sleeve pipe: its technical characteristics is that piston is arranged in sleeve pipe, piston is hollow shape, there is rubber blanket the lower end, there is stage clip the piston top, pull bar is housed in piston, pull bar passes the circular hole of piston upper end and upper sleeve pipe upper end, can freely move up and down, the pull bar bottom is bigger, on bar, cover has extension spring, extension spring is passed piston together with pull bar, the top is limited in below the circular hole of sleeve pipe upper end, the external diameter of pull bar bottom is greater than the circular hole of piston upper end, can drive piston moves up and down in upper sleeve pipe, the pull bar upper end is connected with drag link sleeve, drag link sleeve is enclosed within the upper end of sleeve pipe, can drive pull bar does and slides up and down, lower end one side of drag link sleeve connects crowbar, the crowbar other end is riveted on the centre of crowbar handle, the top of crowbar handle is connected on sleeve pipe, form the lever state, crowbar and crowbar handle can freely be opened, opposite side at upper sleeve pipe is equipped with the stop valve piece, the centre of stop valve piece is riveted on sleeve pipe, can do lever motion, there is a L-type breach upper end of stop valve piece, the bottom of L-type breach embeds in upper sleeve pipe, with the piston sliding-contact, stop valve piece inside lower end has a circular hole, spring is housed, the other end of spring is embedded on the outer wall of sleeve pipe, the front of upper sleeve pipe has a window, bearing spring is housed in setting of casing, cased lower end is furnished with taper taper hood, pin hole is arranged at the hood bottom.

The invention has the advantages that the existing defective for insulin injection pen, the supporting auxiliary device that carries out specialized designs and set up, use the full-automatic insulin injection aid, can not only make the patient eliminate the fear of acupuncture treatment, can also allow the own independent operation of patient, can be in disposable acupuncture treatment and the injection task automatically completed of health any part, bring great convenience for vast diabetics, and manufacturing process is simple, and is with low cost, can be accepted by Most patients.

The specific embodiment

As shown in Figure 1 and Figure 2:

injection pen 14 sleeve pipe of packing into, in upper sleeve pipe 7, piston 3 is arranged, piston 3 is hollow shape, there is rubber blanket 13 lower end, there is stage clip 1 piston 3 tops, pull bar 2 is housed in piston 3, pull bar 2 passes the circular hole of piston 3 and upper sleeve pipe 7 upper ends, can freely move up and down, pull bar 2 bottoms are bigger, on bar, cover has extension spring 10, extension spring 10 is passed piston 3 together with pull bar 2, the top is limited in below the circular hole of sleeve pipe 7 upper ends, the external diameter of pull bar 2 end portions is greater than the circular hole of piston 3 upper ends, can drive piston 3 moves up and down in upper sleeve pipe 7, pull bar 2 upper ends are connected with drag link sleeve 9, drag link sleeve 9 is enclosed within the upper end of sleeve pipe 7, can drive pull bar 2 does and slides up and down, lower end one side of drag link sleeve 9 connects crowbar 11, crowbar 11 other ends are riveted on the centre of crowbar handle 12, the top of crowbar handle 12 is connected on sleeve pipe 7, form the lever state, crowbar 11 and crowbar handle 12 can freely be opened, opposite side at upper sleeve pipe 7 is equipped with stop valve piece 4, the centre of stop valve piece 4 is riveted on sleeve pipe 7, can do lever motion, there is a L-type breach upper end of stop valve piece 4, the bottom of L-type breach embeds in upper sleeve pipe 7, with piston 3 sliding-contacts, there is a circular hole stop valve piece 4 inboards, lower end, spring 5 is housed, the other end of spring 5 is embedded on the outer wall of sleeve pipe 7, the front of upper sleeve pipe 7 has a window 6, bearing spring 8 is housed in setting of casing 15, the lower end of setting of casing 15 is furnished with taper hood 16, pin hole 17 is arranged at hood 16 bottoms.

During use:

injection pen 14 is packed in setting of casing 15, push down bearing spring 8, again upper sleeve pipe 7 is covered the upper end of injection pen 14, upper sleeve pipe 7 is connected with setting of casing connects with screw thread rotation, pull crowbar handle 12, driving crowbar 11 moves upward, pull simultaneously drag link sleeve 9, pull bar 2, stage clip 1, extension spring 10 and piston 3 upwards promote, when the bottom of piston 3 surpasses the position of stop valve piece 4, the top of stop valve piece 4 is under the lifting of bottom spring 5, the bottom surface of L-type breach is embedded the bottom of piston 3, piston 3 is blocked, it can not be fallen, stage clip 1 and extension spring 10 all are extruded and tighten, unclamp crowbar handle 12, extension spring 10 discharges elastic force, with drag link sleeve 9, pull bar 2 and crowbar 11 restore to the original state, this moment is under the effect of bearing spring 8, injection pen 14 is with piston 3 upwards liftings, top contact rubber blanket 13, in the syringe needle indentation hood 16 of afterbody, the dose knob on 6 rotary injection pen 14 tops of the window by upper sleeve pipe 7 again, determine the injected dose that needs, namely having completed injection prepares, during injection, the patient can use the single-hand handling ﹠ Full automatic insulin injection aid, the pin hole 17 of the bottom of hood 16 is directly pressed close to the body part of required injection, then press the lower end of stop valve piece 4, under the effect of lever, the bottom of the breach of stop valve piece 4 upper ends and the bottom of piston 3 break away from, piston 3 landing rapidly downwards under the pressure of stage clip 1 up, because the pressure of stage clip 1 will be much larger than the elastic force of bearing spring 8, therefore when piston 3 falls, injection pen 14 is pressed down rapidly, make syringe needle part moment of injection pen 14 lower ends pass the pin hole 17 of hood 16 bottoms, penetrate patient's subcutaneous tissue, this moment, hood 16 was held injection pen 14, the pressure of top piston 3 continues to press to by rubber blanket 13 dose knob on injection pen 14 tops, slowly inject medicinal liquid in patient body, thereby realized the disposable task of automatically completing acupuncture treatment and injection.
