Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

An insulin injection pen as shown in fig. 1 to 3 comprises an injection pen assembly 10, an electronic assembly 20 and an operation assembly 30.

The injection pen assembly 10 is used to operate the injection of insulin. Electronic component 20 sets up on the injection pen subassembly for the dose of insulin injection each time is reminded and reported in the timing of insulin injection. The operation component 30 is electrically connected with the electronic component and is used for specifically adjusting the reminding time.

In one embodiment, as shown in FIG. 2, injection pen assembly 10 includes a first housing 11 having a longitudinal first end 111 with a threaded groove 112 disposed on an inner sidewall thereof. The cross section of the thread groove can be semicircular, triangular and the like. As shown in fig. 3, in the first end there are also arranged sliding fits several sliders 12, which are evenly distributed along the trajectory of the thread groove. Specifically, the distance between two adjacent sliders in the axial length is one unit of the length distance on the insulin refill. It should be noted that the inner end of the slider can radially protrude into the first housing. Meanwhile, the outer end of the sliding block is fixedly provided with an electrode plate 13, preferably, the electrode plate is made of graphene and has extremely strong conductivity and certain flexibility. In addition, a second housing 14 is also slidably received over the first end. The sliding block is sleeved with a spring 15, the spring is in a compressed state, one end of the spring is propped against the inner wall of the second shell, and the other end of the spring is propped against the sliding block, so that the sliding block is subjected to an acting force pushing the sliding block inwards. At the same time, the injection pen assembly 10 further comprises a dose knob 16 having a surface with threads 161 that mate with the thread grooves, and which, when the dose knob is fully screwed into the first end, ejects the portion of the slider that extends from the inner end into the interior of the first housing. At the same time, 14 the electronic component 20 is mounted on the second housing.

As shown in fig. 4 and 5, the electronic assembly 20 includes a piece of flexible circuit board 21 annularly attached to the inner wall of the second housing. Contacts 211 are provided on the flexible circuit board in one-to-one correspondence with each electrode pad. Meanwhile, a singlechip 22, a loudspeaker 23, a power supply 24 and the like are fixedly arranged on the second shell. Wherein, the flexible circuit board 21, the loudspeaker 23 and the power supply 24 are all electrically connected with the singlechip. In the specific implementation, when the electrode pads are pressed against the flexible circuit board, the circuit board is in a charging state, and when the dose knob 16 is screwed axially outward out of the first end, the electrode pads 13 pressed against the flexible circuit board by the threads 161 on the surface of the dose knob are disengaged from the contacts on the flexible circuit board under the action of the spring. At the moment, the corresponding circuit which is conducted through the contact of the electrode plates in the flexible circuit board is powered off to generate a pulse signal, the pulse signal is transmitted to the single chip microcomputer which is electrically connected with the pulse signal and then triggers an internal preset program, the single chip microcomputer sends an instruction to the loudspeaker, and the loudspeaker immediately broadcasts a corresponding dosage value. Specifically, the first shell has a second end opposite to the first end. The number of doses that can be triggered by the contacts on the flexible circuit board increases from near the second end 112 to far from the second end. Preferably, in order to protect the electronic components, a cavity 141 may be disposed on the second housing, and the single chip, the power supply, and the speaker are all fixedly mounted in the cavity. Meanwhile, the single chip microcomputer can be preset with reminding time, such as 11:00 reminding time, 11:30 reminding time and the like. And when the preset time point is reached, the singlechip is triggered and controls the loudspeaker to give out an insulin injection prompt.

It should be noted that in the present invention, the dosage window 113 of the first housing remains. Meanwhile, the dose value (not shown) on the conventional dose knob 16 is also retained, and during the process of screwing the dose knob, the patient can observe the corresponding change of the dose value through visual observation to realize mutual verification of the display value and the broadcast value.

As a further improvement of the above embodiment, in order to enable the contacts 211 on the flexible circuit board 21 to be more easily aligned with the electrode pads 13 at the time of assembly. A guide groove 142 is provided on the inner side wall of the second housing remote from the first end 111. Meanwhile, a guide block 114 is disposed on the outer surface of the first housing 11 to fit the guide groove.

As a further modification of the above embodiment, the second housing 14 is provided with a charging port 25 which is electrically connected to the power supply 24, and the power supply is charged to thereby reuse the power supply.

As a further improvement of the above embodiment, in order to realize flexible adjustment of the reminding time, the operation assembly 30 comprises a display screen 31 and an adjusting button 32 which are electrically connected with the single chip microcomputer. The single chip microcomputer is triggered by pressing the adjusting button so as to achieve the purpose of changing the reminding time. The display screen serves the purpose of adjusting the time value in reality.

In the above embodiment, it should be noted that the operating assembly 10 further includes an injection mechanism 17 detachably mounted on the first and second ends 112. Specifically, the injection mechanism comprises a cartridge holder 171, which is hollow in the middle and provided with a scale (not shown) on the surface thereof, so as to facilitate the patient to observe the remaining insulin dosage in the insulin cartridge. A needle 172 is detachably arranged at the front end of the pen refill holder. The needle head is a disposable consumable material, and needs to be replaced every injection. A screw 173 is also provided in the first housing for pressing the insulin pen core. In addition, the outside of the injection mechanism is also sleeved with a pen cap 18, which is used for ensuring that the inside of the utility model is not polluted by external pollution sources when not used.
