It should be understood that, the disease condition of the type 1 diabetes patient is serious, therefore, the insulin pump with good curative effect is needed for treatment, the disease condition of the type 2 diabetes patient and the gestational diabetes patient is relatively light, and various treatment schemes are provided, while the general insulin pump is expensive and troublesome to use, and is not accepted by the type 2 diabetes patient and the gestational diabetes patient, and the driving reset insulin pump in the application can greatly reduce the use cost for long-time use, has relatively low price, and is convenient to carry and use, namely, is convenient to popularize for the type 2 diabetes patient and the gestational diabetes patient.

As shown in fig. 2 and fig. 5, in this embodiment, the actuating assembly 2 includes a driving member 22, a supporting housing 23, a swinging member 24 movably disposed on the supporting housing 23 and disposed corresponding to the driving member 22, a ratchet mechanism 25 rotatably disposed on the supporting housing 23 and disposed corresponding to the swinging member 24, and a lead screw sleeve 26 fixedly disposed in the ratchet mechanism 25 and sleeved outside the pushing screw 21, the lead screw sleeve 26 is in threaded connection with the pushing screw 21, the driving member 22 is used for driving the swinging member 24 to swing, the ratchet mechanism 25 is used for driving the lead screw sleeve 26 to rotate, the lead screw sleeve 26 is used for driving the pushing screw 21 to extend, push or retract to reset, the swinging member 24 is used for driving the ratchet mechanism 25 to rotate forward to drive the lead screw sleeve 26 to rotate forward to drive the pushing screw 21 to extend out and push the lead screw sleeve 26, and the reset member 52 is respectively detachably connected with the pushing screw 21 and the ratchet mechanism 25 to rotate backward to drive the lead screw sleeve 26 to rotate backward so as to rotate backward The pushing screw 21 is driven to contract and reset in the screw sleeve 26. Specifically, the swing piece 24, the ratchet mechanism 25, the screw rod sleeve 26 and the pushing screw rod 21 are stably supported through the supporting shell 23, so as to ensure the reliability of the mutual movement among the swing piece 24, the ratchet mechanism 25, the screw rod sleeve 26 and the pushing screw rod 21, when the liquid medicine is injected, the driving piece 22 drives the swing piece 24 to swing back and forth so as to drive the ratchet mechanism 25 to rotate in a stepping forward direction, further drive the screw rod sleeve 26 to rotate in a stepping forward direction, further drive the pushing screw rod 21 to extend in a stepping manner and push, so as to inject the liquid medicine into the patient, after the liquid medicine is injected, the ratchet mechanism 25 and the pushing screw rod 21 are connected with the reset piece 52, so that the reset piece 52 drives the ratchet mechanism 25 to rotate in a reverse direction, further drives the screw rod sleeve 26 to rotate in a reverse direction, further drive the pushing screw rod 21 to retract and reset in the screw rod sleeve 26, so that the execution assembly 2 can push the next injection assembly 1, the injection of the next syringe assembly 1 is completed. It should be understood that the push screw 21 and the injection assembly 1 or the reset element 52 are detachably connected, and when the ratchet mechanism 25 drives the screw sleeve 26 to rotate, the push screw 21 can only move in the axial direction to complete the injection operation of the injection assembly 1 or move in the axial direction to achieve the retraction reset, but cannot rotate synchronously with the rotation of the screw sleeve 26, that is, the push screw 21 is circumferentially fixed.

As shown in fig. 3, in the present embodiment, the ratchet mechanism 25 includes a rotating shaft 251 rotatably disposed on the supporting housing 23 and fixedly sleeved outside the screw sleeve 26, a ratchet 252 unidirectionally rotatably sleeved outside the rotating shaft 251, and a plurality of ratchet teeth sequentially arranged along the circumferential direction of the ratchet 252, and the rotating shaft 251 is detachably connected to the reset member 52. Specifically, when the liquid medicine needs to be injected, the swinging piece 24 pushes the ratchet to drive the ratchet wheel 252 to rotate forward, at the moment, the ratchet wheel 252 drives the rotating shaft 251 to rotate forward, and further drives the screw rod sleeve 26 to rotate forward, so that the extension and pushing of the connecting and pushing screw rod 21 are realized; when the reset member 52 drives the rotating shaft 251 to rotate reversely, the rotating shaft 251 rotates reversely relative to the ratchet 252, that is, the ratchet 252 is fixed differently and does not abut against and interfere with the swinging member 24, the rotating shaft 251 drives the screw rod sleeve 26 to rotate reversely, and further drives the pushing screw rod 21 to move axially to retract and reset in the screw rod sleeve 26. Alternatively, the rotating shaft 251 has a sleeve structure with a hollow interior.

As shown in fig. 1, in the present embodiment, the reset member 52 includes a reset motor 521, a connecting sleeve 522 disposed on an output shaft of the reset motor 521 and detachably connected to the rotating shaft 251, and a movable sleeve detachably connected to the pushing screw 21 and used for preventing the pushing screw 21 from rotating circumferentially. Specifically, the reset motor 521 works to drive the output shaft to rotate, and further drive the connecting sleeve 522 to rotate, so as to drive the rotating shaft 251 to rotate, and finally drive the screw rod sleeve 26 to rotate, and since the movable sleeve prevents the pushing screw rod 21 from rotating circumferentially, the pushing screw rod 21 moves axially relative to the screw rod sleeve 26, so as to achieve the retraction and reset of the pushing screw rod 21. Optionally, the movable sleeve includes a movable sleeve coaxially disposed with the pushing screw rod 21, a movable limiting block movably disposed in the movable sleeve along the axial direction and detachably connected to an extending end of the pushing screw rod 21, and a supporting seat supporting the movable sleeve from the bottom, and is connected to the pushing screw rod 21 through the movable limiting block, so as to prevent the pushing screw rod 21 and the screw rod sleeve 26 from rotating circumferentially and synchronously.

As shown in fig. 5, in the present embodiment, the driving member 22 includes an electromagnet 221 and a power supply member 222 electrically connected to the electromagnet 221, the electromagnet 221 includes two magnetic poles arranged at intervals and having opposite directions, and the power supply member 222 is configured to change the magnetism and the direction of the two magnetic poles at a preset frequency to drive the oscillating member 24 to oscillate back and forth. Specifically, the current is transmitted to the electromagnet 221 through the power supply element 222, so that the electromagnet 221 generates two magnetic poles with magnetism and opposite directions, and further attracts a repelling oscillating element 24, so that the oscillating element 24 oscillates in a direction close to one of the magnetic poles under the action of the magnetic force, at this time, the power supply element 222 changes the directions of the two magnetic poles by changing the positive and negative poles of the output current, so that the oscillating element 24 oscillates in a direction close to the other magnetic pole under the action of the magnetic force, based on the above working principle, the direction of the two magnetic poles is changed by the power supply element 222 according to a preset frequency, so that the oscillating element 24 oscillates in a reciprocating manner in an extending region between the two magnetic poles along with the change of the directions of the two magnetic poles, and further drives the pushing screw rod 21 to extend out and push, so as to drive the injection assembly 1 to inject the liquid medicine, the power output is more stable, direct and reliable by adopting electromagnetic driving, which is beneficial to accurately control the injection amount of the insulin to the patient, the health of a patient is guaranteed, meanwhile, the electromagnetic energy conversion efficiency is high relative to the electrothermal energy conversion efficiency, the power consumption is low, the service life is long under the condition of the same electric power, and the patient can use the electromagnetic energy conversion device for a long time conveniently. It will be appreciated that the preset frequency determines the frequency of the reciprocal oscillation of the oscillating member 24 and thus the injection speed of the liquid medicine, i.e. it can be adaptively adjusted according to the needs of the patient. Alternatively, the preset frequency is 5 ms/time, that is, the current flowing direction of the power supply unit 222 is changed every 5 ms to change the direction of the two poles of the electromagnet 221, so as to achieve the rapid injection of the liquid medicine. Alternatively, the electromagnet 221 is disposed in a "U" shape, and two magnetic poles are disposed at two end portions of an opening end of the electromagnet 221, respectively. It should be understood that when the electromagnet 221 is in a quiescent state, the magnetic pole pointing north is called a north pole and the magnetic pole pointing south is called a south pole, and the power supply 222 changes the orientation of the magnetic poles, meaning that the north pole is changed to the south pole and the south pole is changed to the north pole. It should be understood that when the power supply 222 supplies current to the electromagnet 221, the electromagnet 221 is magnetic and generates magnetic force that attracts and repels the swinging member 24, thereby driving the urging screw 21 to extend and urge; when the power supply 222 does not supply current to the electromagnet 221, the electromagnet 221 stops operating, and accordingly, the pushing screw 21 also fails to operate. It should be appreciated that in another embodiment, the driving member 22 uses a memory alloy to drive the oscillating member 24 to oscillate.

As shown in fig. 3, in the present embodiment, the supporting housing 23 includes a connection post 231 disposed along the height direction of the supporting housing 23, the swinging member 24 is rotatably sleeved on the connection post 231, and the swinging member 24 includes a magnetic attraction portion 241 disposed in the extension region between the two magnetic poles and keeping a predetermined distance from the electromagnet 221 for swinging back and forth along with the change of the magnetic properties of the two magnetic poles, and a pushing portion 242 for pushing against the rotation of the ratchet mechanism 25 along with the back and forth swinging of the magnetic attraction portion 241. Specifically, the electromagnet 221 drives the magnetic part 241 to swing repeatedly to drive the abutting part 242 to swing repeatedly, and further abut against the ratchet mechanism 25, so as to realize the step-by-step rotation of the ratchet mechanism 25, and further drive the abutting screw rod 21 to extend out of the abutting injection assembly 1, thereby completing the injection operation. Optionally, the magnetic attracting portion 241 is made of a ferromagnetic material. Optionally, the magnetic attracting portion 241 is an electromagnet. It should be understood that, since the magnetic attraction portion 241 and the electromagnet 221 maintain a preset distance, the magnetic attraction portion 241 of the oscillating member 24 is not hindered and interfered by the magnetic pole during the oscillating process, the oscillating range is large, so that the oscillating portion covers a small number of structures, which is convenient for simplification and light weight design, the self gravity of the oscillating portion can be neglected and ignored for the driving power of the driving member 22, and the influence on the driving member 22 is small along with the different postures or posture changes of the insulin pump during use. It should be understood that the larger the current supplied by the power supply 222, the larger the magnetic force of the two magnetic poles on the electromagnet 221, and the faster the swing speed of the magnetic attraction portion 241. It should be understood that the extension area between the two poles refers to the area in which the middle area of the two poles extends towards the actuating assembly 2.

As shown in fig. 3, in this embodiment, a plurality of limiting protrusions 232 extending along the width direction of the supporting housing 23 are disposed on the side wall of the supporting housing 23, the limiting protrusions 232 are disposed at intervals along the length direction of the supporting housing 23 to form limiting grooves, the swinging member 24 further includes limiting holes 243 disposed along the thickness direction of the swinging member 24 and corresponding to the limiting grooves, and limiting blocks 244 disposed in the limiting holes 243, and a limiting end of the limiting block 244 extends into the limiting groove and is used for abutting against the limiting protrusions 232 to limit the swinging range of the swinging member 24 in the swinging process of the swinging member 24. Specifically, in the swinging process of the swinging member 24, the limiting block 244 swings synchronously, and the limiting end of the limiting block 244 extends into the limiting groove and is abutted and limited by the limiting protrusion 232, so that the swinging member can only swing in the limiting groove, the swinging range of the swinging member 24 is correspondingly limited, the situation that the pushing part 242 is separated from the pushing area of the ratchet due to the overlarge swinging range of the swinging member 24 is avoided, the interference and the blocking of the ratchet are possibly caused, and the movement stability and reliability of the magnetic attracting member are ensured. Optionally, the limiting groove is disposed along the length direction of the supporting housing 23, the length direction of the supporting housing 23 is the same as the swinging direction of the magnetic attracting portion 241, so that the limiting block 244 is slidably disposed in the limiting groove along the swinging direction, and the limiting block 244 slides in the limiting groove to appropriately increase the swinging range of the swinging member 24, thereby avoiding that the swinging range of the swinging member 24 is too small and the pushing stroke of the pushing portion 242 is too small, so that the rotation speed of the ratchet 252 is too slow, and further affecting the injection speed of the injection assembly 1. It should be understood that the preset distance may be adaptively adjusted according to the production requirement of the product, and the magnetic attraction portion 241 may swing.

As shown in fig. 3, in this embodiment, the end of the support housing 23 far away from the magnetic attraction portion 241 is provided with a plurality of limiting posts 233 arranged along the height direction of the support housing 23, the plurality of limiting posts 233 are arranged at intervals along the length direction of the support housing 23 to form a limiting gap, and the end of the swinging member 24 far away from the magnetic attraction portion 241 is provided with a limiting portion 245 extending along the length direction of the swinging member 24 and extending into the limiting gap for abutting against the limiting posts 233 in the swinging process of the swinging member 24 to limit the swinging range of the swinging member 24. Specifically, in the swinging process of the swinging member 24, the limiting portion 245 swings synchronously, and the limiting portion 245 extends into the limiting gap and is abutted and limited by the limiting column 233, so that the swinging member can only swing in the limiting gap, the swinging range of the swinging member 24 is correspondingly limited, the situation that the abutting portion 242 is separated from the abutting and pushing area of the ratchet due to the overlarge swinging range of the swinging member 24 is avoided, and the swinging member is possibly interfered by the interference of the ratchet and is clamped, and the stable and reliable movement of the swinging member 24 is ensured.

In the embodiment, as shown in fig. 3, the swinging member 24 further includes an elastic member 246 sleeved on the connection post 231 for pressing the swinging member 24. Specifically, the elastic member 246 presses against the swinging member 24, so that the pressing portion 242 on the swinging member 24 is always in the same horizontal plane with a ratchet on the ratchet wheel 252, and further always presses against a ratchet to move step by step along the tangential direction of the ratchet wheel 252, thereby realizing the step by step rotation of the ratchet wheel 252. Optionally, the resilient member 246 is a compression spring.

As shown in fig. 4, in the present embodiment, a plurality of ratchet wheels 252 are arranged along the axial direction of the rotating shaft 251, and the pushing portions 242 and the ratchet wheels 252 are arranged in a one-to-one correspondence. Specifically, the two pushing portions 242 are respectively disposed on two opposite sides of the magnetic attracting portion 241 of the magnetic attracting member, and in the process of the reciprocating swing of the magnetic attracting portion 241, the two pushing portions 242 sequentially and reciprocally push the ratchets on the two ratchet wheels 252, so as to greatly increase the rotation speed of the ratchet wheels 252. It should be understood that when the magnetic attracting portion 241 moves toward a direction close to one of the magnetic poles, the pushing portion 242 close to the magnetic pole pushes the corresponding ratchet on the ratchet wheel 252, so as to rotate the ratchet wheel 252; when the magnetic part 241 moves toward the direction close to the other magnetic pole, the pushing part 242 close to the other magnetic pole pushes the corresponding ratchet on the ratchet 252, so that the ratchet 252 rotates, because the two ratchet 252 rotate synchronously through the rotating shaft 251, i.e. one of the ratchet 252 rotates, the other ratchet 252 also rotates synchronously, the magnetic part 241 swings back and forth once, so that the ratchet 252 rotates twice, and the rotating speed of the ratchet 252 is greatly increased.

As shown in fig. 1, in the present embodiment, the energy assembly 4 includes a charging socket, and the charging element 51 includes a charging base 511 and a charging plug 512 disposed on the charging base 511 for being inserted into the charging socket. Specifically, after injection of syringe assembly 1 is completed, actuating assembly 2 is detached from syringe assembly 1, and then the charging socket is mated with charging plug 512 to charge the energy source assembly 4. Optionally, the charging member 51 comprises a charging wire, and the charging plug 512 is disposed on the movable end of the charging wire.
