Description

Integrated full-automatic insulin injection pen

Technical Field

The invention relates to an injector, in particular to an integrated full-automatic insulin injection pen.

Background

Prior to the present invention, there have been several automatic or semi-automatic inventions to assist diabetics with insulin injections, such as: the invention relates to a full-automatic insulin injection assistor, an insulin automatic injector and an automatic needle pricking type injection pen, wherein the first two invention schemes are that a debugged injection pen is arranged in an invention device and then operated, so that the automation of needle pricking and liquid medicine injection can be realized, but the device has larger volume, is troublesome to assemble and inconvenient to carry, the latter invention can complete automatic needle pricking but cannot realize automatic liquid medicine injection, at present, an injection pen capable of automatically injecting liquid medicine is also arranged on the market, but cannot realize automatic needle pricking, and in a word, the invention and the product have certain defects, and cannot really bring convenience to diabetics.

Disclosure of Invention

The invention overcomes the defects, designs and develops an integrated full-automatic insulin injection pen.

The technical scheme of the invention is as follows:

The invention has the advantages that the invention carries out special combination and modification design aiming at the existing advantages and disadvantages of various insulin injectors, and uses the integrated full-automatic insulin injection pen, so that the patient can independently operate to complete automatic needle insertion and liquid medicine injection at any part of the body, thereby thoroughly eliminating the fear of needle insertion and the trouble of pressing and injecting liquid medicine, and bringing great convenience to the majority of diabetic patients.

Drawings

FIG. 1 is a schematic diagram of the structural principle of the present invention.

Fig. 2 is a schematic view of the present invention in a state of completing automatic needle insertion and injection.

Detailed Description

As shown in fig. 1 and 2:

the main pen body 9 is arranged in an upper shell 12 and a lower shell 14, the upper shell 12 is connected with the lower shell 14 in a plugging mode, the top end of the main pen body 9 is provided with a knob 1, the lower side of the knob 1 is provided with an observation hole 2, one side of the upper shell 12 is externally provided with a key 3 which corresponds to a bayonet 4 on the main pen body 9, a convex groove 6 is arranged below the key 3, a liquid medicine compressor 11 is arranged in the main pen body 9, the upper end of the liquid medicine compressor 11 is connected with the knob 1, the lower end of the liquid medicine compressor is in tooth-shaped meshing contact with a control valve 13, a top spring 7 is sleeved under the control valve 13, one side of the top end of the control valve 13 is in contact with a ball 5, the ball 5 corresponds to the position of the convex groove 6, the lower part of the main pen body 9 is sleeved with a spring 8, the main pen body 9 can move up and down in the upper shell 12 and the lower shell 14, the upper end of the upper shell 12 is provided with a window 10, and the bottom of the lower shell 14 is provided with a pinhole 15.

When in use:

the lower casing 14 is firstly pulled out from the upper casing 12 to expose the lower end of the main pen body 9, the liquid medicine and the needle head are contained, then the lower end of the main pen body 9 is held to push the main pen body 9 upwards, when the bayonet 4 on the main pen body 9 reaches the position of the key 3, the upper part of the key 3 is embedded into the bayonet 4 to clamp the main pen body 9, meanwhile, the ball 5 on the main pen body 9 is lifted to the position of the convex groove 6, under the action of the top spring 7, the ball 5 is squeezed into the convex groove 6 by the control valve 13 to be released from the control valve 13, the control valve 13 is engaged and contacted with the lower end of the liquid medicine compressor 11, then the knob 1 is twisted to drive the liquid medicine compressor 11 to rotate clockwise, the dosage required to be injected is observed from the window 10, the liquid medicine engaged compressor 11 is locked by the control valve 13 after the rotation is stopped, the spring 8 is simultaneously in a contraction state, then the lower casing 14 is inserted back into the upper casing 12, at the time, the needle head at the tail part of the main pen body 9 is also retracted into the lower casing 15, the injection preparation is completed, and when injecting, the patient can hold the upper shell 12 with one hand, directly press the needle hole 15 at the bottom of the lower shell 14 to the body part needing to be injected, then the key 3 is pressed down, when the key 3 is separated from the bayonet 4, the elastic force of the spring 8 is released rapidly to drive the main pen body 9 to move downwards integrally, so that the needle head at the lower end of the main pen body 9 penetrates through the needle hole 15 at the bottom of the lower shell 14 to be pricked into the subcutaneous tissue of a patient, the automatic pricking task is completed firstly, meanwhile, as the main pen body 9 falls down, the ball 5 is driven to leave the convex groove 6 and slide down along the inner wall of the upper shell 12 and extrude the control valve 13, the control valve 13 is forced to loosen the liquid medicine compressor 11, the liquid medicine compressor 11 rotates anticlockwise, pressure is released, liquid medicine is injected to the subcutaneous part of a patient, thereby completing the tasks of automatic needle insertion and automatic liquid medicine injection at one time, and the patient can also check the injection completion condition through the observation hole 2.
