Description

Technical Field

[0001] This invention relates to the field of medical injection pen technology, and more particularly to an intelligent electronic dose-adjustable injection pen. Background Technology

[0002] Current medical syringes (injection pens) primarily rely on mechanical rotating parts for dosage setting, such as a rotating scale ring on the pen body and a plunger for advancement. Patients must manually rotate specific adjustment components to align the dosage value with the scale markings to set the desired injection dose. Only after visually verifying the dosage against the pen body's scale can the subsequent injection procedure be performed. The entire process, from dosage setting to final injection, depends entirely on manual operation and visual verification of the scale, requiring a certain level of skill, dexterity, and vision from the patient. This is especially problematic for elderly individuals with reduced dexterity and poor vision; long-term overdose or underdose injections can significantly harm their recovery or overall health.

[0003] In existing technologies, the dosage setting of clinically used injection pens relies on manually rotating a component, making operation relatively complex. Patients are prone to dosage adjustments due to deviations in rotation angle or misreading the scale. This is particularly significant for patients with chronic diseases (such as diabetes) who require frequent use: repeated operation can easily lead to hand fatigue, further increasing the probability of errors. Once the dosage is incorrect, it not only affects the treatment effect but also poses safety risks. In addition, for patients with poor finger dexterity (such as elderly people with joint degeneration) or poor vision, it is difficult to accurately rotate the component and see the scale, which not only directly reduces the accuracy and efficiency of dosage adjustment but also increases their daily burden. Summary of the Invention

[0004] The purpose of this invention is to address the problems existing in the background art by proposing an intelligent electronic dose-adjusting injection pen.

[0005] The technical solution of the present invention: an intelligent electronic dose-adjustable injection pen, comprising a support cylinder, and further comprising: a manual injector movably mounted on one end of the support cylinder, the manual injector having an adjustment knob sleeve, a display indicator, and an injection button; a retaining sleeve fixedly connected to one end of the support cylinder and slidably sleeved with the manual injector, one end of the support cylinder having a locking mechanism for fixing the manual injector inside the support cylinder; a docking mechanism disposed inside the support cylinder and engaging with the adjustment knob sleeve on the manual injector; a mounting groove formed inside the support cylinder, the mounting groove having a transmission mechanism for driving the docking mechanism to rotate; a pushing mechanism located inside one end of the support cylinder that drives the injection button to open when opened; and a reading mechanism mounted on the support cylinder and aligned with the display indicator on the manual injector.

[0006] Optionally, the locking mechanism includes a second cylinder fixedly connected to one end of the support cylinder near the ferrule, and a locking block that abuts against the manual syringe is fixedly connected to one end of the second cylinder. The locking block has an arc-shaped groove that fits tightly against the outer wall of the manual syringe.

[0007] Optionally, the docking mechanism includes a support plate fixedly connected inside the support cylinder. The support plate has a positioning hole in the middle for inserting the injection button. The support plate also has a rotating groove. A rotating block is rotatably connected inside the rotating groove. An internal gear sleeve that meshes with the adjusting knob gear sleeve is fixedly connected to one end of the rotating block away from the support plate.

[0008] Optionally, the transmission mechanism includes a motor fixedly connected in the mounting slot, the output shaft of the motor being fixedly connected to a pulley, and a belt being fitted onto the pulley and the internal gear sleeve.

[0009] Optionally, both the pulley and the internal gear sleeve are provided with slots for securing the belt.

[0010] Optionally, the pushing mechanism includes a first cylinder fixedly connected inside one end of the support cylinder, and the piston rod of the first cylinder is fixedly connected to a pressing block that is inserted into the positioning hole and abuts against the injection button.

[0011] Optionally, a hand handle is fixedly connected to the outer wall of the support cylinder, and a motor button that can be manually pressed to turn on the motor is provided at one end of the hand handle near the support cylinder.

[0012] Optionally, the end of the pulley away from the motor output shaft is rotatably connected to the inner wall of the mounting groove.

[0013] Optionally, the manual syringe has an injection needle at the end away from the cartridge sleeve, and a protective pen cap is sequentially fitted at the end of the manual syringe near the injection needle.

[0014] In summary, this application includes at least one of the following beneficial technical effects:

[0015] This invention utilizes a combination of a support cylinder, transmission mechanism, reading mechanism, and pushing mechanism. When using the intelligent electronic dosage adjustment injection pen, a manual syringe is secured by a clamping sleeve and locking mechanism, while the reading mechanism reads and displays information for voice prompts. Pressing the motor button activates a motor via belt drive, rotating an internal gear sleeve that engages with the adjustment knob's gear sleeve to achieve automatic dosage adjustment without manual rotation. After dosage adjustment, the first cylinder pushes the press block to trigger the injection button. This reduces manual operation, avoids rotational deviations and misreading of scales, and lowers the burden and risk of error for patients with chronic diseases, those with dexterity issues, or poor eyesight.

[0027] Example

[0028] like Figures 1 to 4As shown, the intelligent electronic dose-adjustable injection pen proposed in this invention includes a support cylinder 1 and a manual syringe 3 movably mounted on one end of the support cylinder 1. The manual syringe 3 is a conventional manually operated injection pen used to load medication. Its adjustment knob sleeve 31, display label 32, and injection button 33, in conjunction with other structures, enable dose adjustment and injection operations. A hand handle 11 is fixedly connected to the outer wall of the support cylinder 1. The hand handle 11 has a groove inside, containing a micro-battery that powers the motor 71. The support cylinder 1 has two modes: one with a handle: the pen body is equipped with an ergonomic hand handle 11, providing more even force distribution when gripped, especially suitable for people with weak hand strength and poor dexterity (such as the elderly and arthritis patients). It allows for stable force application when adjusting the dose, reducing dose deviation caused by hand tremors and increasing operational safety. The second mode is without a handle: the support cylinder 1 without the hand handle 11 adopts an integrated, streamlined body design, making it smaller and more portable, easily fitting into a pocket or medicine box, and easy to carry when out and about. Suitable for users with normal hand function who prioritize simple operation and portability, the support cylinder 1 can be directly held when adjusting the dosage, making operation simpler and daily use convenient and efficient. When the support cylinder 1 is set without a handle, it needs to be thickened to ensure that the micro battery and motor 71 inside the handle 11 can be installed inside the support cylinder 1. Among the wireless charging technologies used for the micro battery, the most widely used is electromagnetic induction based on the electromagnetic coupling of two coils. The specific process is that after the transmitting coil of the wireless charger is connected to an AC power source, it generates a high-frequency alternating current, which in turn excites an alternating magnetic field. When the receiving coil of the micro device containing the micro battery approaches this magnetic field, it induces an alternating current of the same frequency. This current is converted into DC power by a micro rectifier circuit, and then adjusted to the rated charging parameters of the micro battery by a micro voltage regulator chip or DC-DC converter, ultimately achieving stable charging. The support cylinder 1 and the hand handle 11 are made of carbon fiber, which offers several advantages: significant weight reduction (30%-50% lighter than traditional plastics), improving portability; high strength and rigidity, impact resistance, wear resistance, and extended service life; resistance to chemical corrosion, resisting the erosion of cleaning agents such as alcohol, making it suitable for medical equipment applications; good thermal stability, maintaining dimensional stability under high and low temperature environments, ensuring the function of precision components; and excellent moldability, allowing for complex shaping while balancing structural strength and design flexibility, especially suitable for products such as smart injection pens that require both durability and portability. The hand handle 11 facilitates user grip on the device, improving stability during operation. A motor button 8, manually pressed to activate the motor 71, is located near the end of the hand handle 11 close to the support cylinder 1. The manual syringe 3 is equipped with an adjustment knob sleeve 31, a display indicator 32, and an injection button 33. The adjustment knob sleeve 31 engages with an internal gear sleeve 74, rotating under its influence to adjust the dosage. The display indicator 32 displays the injection dosage information for the reading mechanism 4 to read.The injection button 33 is activated when pushed against by the pressing block 61, triggering the injection operation. A retaining sleeve 2 is fixedly connected to one end of the support cylinder 1, which slides and engages with the manual syringe 3, providing initial positioning and guidance. A locking mechanism is provided at one end of the support cylinder 1 to secure the manual syringe 3 inside the support cylinder 1.

[0029] Secondly, such as Figure 1 and Figure 3 As shown, the support cylinder 1 is provided with a docking mechanism that engages with the adjusting knob toothed sleeve 31 on the manual syringe 3. The support cylinder 1 is provided with an installation groove 7, and the installation groove 7 is provided with a transmission mechanism that drives the docking mechanism to rotate. One end of the support cylinder 1 is provided with a push mechanism that drives the injection button 33 to open after being opened. The support cylinder 1 is equipped with a reading mechanism 4 that aligns with the display mark 32 on the manual syringe 3. The reading mechanism 4 is based on the same principle as the reading mechanism in the intelligent reading tape measure.

[0030] The reading mechanism 4 is a device or system that converts changes in physical quantities (such as length, angle, and displacement) into identifiable and readable information (such as digital or electrical signals). Its core function is to replace manual observation, enabling automatic detection and information extraction of specific physical quantities. Furthermore, the reading mechanism 4 achieves dose reading through a four-step closed loop of sensing, conversion, processing, and output, with each step specifically adapted to the injection pen scenario.

[0031] Sensing components: Centered on a miniature camera (with supplemental lighting to capture scale and numbers) or an optical sensor (to identify changes in light on the scale lines), these components accurately capture the dosage scale information of the injection pen, replacing the process of human eyes "seeing".

[0032] Conversion component: Through image recognition module (OCR to identify the number of numbers or scale lines) or signal processing circuit (to convert light signals into digital pulses), visual information is converted into digital signals that the machine can process, so as to "understand" the scale.

[0033] Processing component: The control chip acts as the "brain," verifying digital signals (filtering outliers), matching units (such as "units"), and confirming the final dose after the scale stabilizes, ensuring information accuracy.

[0034] Output format: Information is delivered via a voice module (broadcasting "unit"), adapting to scenarios with poor eyesight or low lighting, allowing users to quickly obtain results.

[0035] Secondly, such as Figures 1 to 3As shown, the locking mechanism includes a second cylinder 9 fixedly connected to one end of the support cylinder 1 near the ferrule 2. The second cylinder 9 serves as the power source for the locking mechanism, driving the locking block 91 to move. One end of the second cylinder 9 is fixedly connected to the locking block 91, which abuts against the manual syringe 3. The locking block 91 is connected to one end of the second cylinder 9, and its arc-shaped groove is tightly against the outer wall of the manual syringe 3, fixing it inside the support cylinder 1. The locking block 91 has an arc-shaped groove that fits tightly against the outer wall of the manual syringe 3.

[0036] In addition, such as Figures 2 to 4 As shown, the docking mechanism includes a support plate 5 fixedly connected inside the support cylinder 1. A positioning hole 51 is provided in the middle of the support plate 5 for inserting the injection button 33, thus positioning the injection button 33. A rotating groove 52 is also provided on the support plate 5, providing rotational space for the rotating block 76 and ensuring its stable rotation. The rotating block 76 is rotatably connected inside the rotating groove 52, with one end connected to an internal gear sleeve 74, providing rotational support for the internal gear sleeve 74. An internal gear sleeve 74, meshing with the adjusting knob gear sleeve 31, is fixedly connected to the end of the rotating block 76 away from the support plate 5. The internal gear sleeve 74 is connected to the rotating block 76, with one end meshing with the adjusting knob gear sleeve 31, rotating under the drive of the belt 73 and driving the adjusting knob gear sleeve 31.

[0037] It is worth noting that, such as Figures 2 to 4 As shown, the transmission mechanism includes a motor 71 fixedly connected in the mounting groove 7. The motor 71 serves as the power source for the transmission mechanism, and its output shaft drives the pulley 72 to rotate. The output shaft of the motor 71 is fixedly connected to the pulley 72, which rotates under the drive of the motor 71, driving the internal gear sleeve 74 to rotate via a belt 73. A belt 73 is fitted onto the pulley 72 and the internal gear sleeve 74, transmitting the rotation of the pulley 72 to the internal gear sleeve 74. Both the pulley 72 and the internal gear sleeve 74 have slots 75 for securing the belt 73, preventing it from slipping off during transmission. The end of the pulley 72 furthest from the output shaft of the motor 71 is rotatably connected to the inner wall of the mounting groove 7.

[0038] Furthermore, such as Figures 2 to 3 As shown, the pushing mechanism includes a first cylinder 6 fixedly connected inside one end of the support cylinder 1. The first cylinder 6 serves as the power source for the pushing mechanism, and its piston rod can drive the pressing block 61 to move. The piston rod of the first cylinder 6 is fixedly connected to the pressing block 61, which is inserted into the positioning hole 51 and abuts against the injection button 33. The pressing block 61 is connected to the piston rod of the first cylinder 6, inserted into the positioning hole 51, and abuts against the injection button 33. Under the drive of the cylinder, the button is pushed open.

[0039] Furthermore, such as Figures 1 to 3 As shown, the end of the manual syringe 3 away from the sleeve 2 is provided with an injection needle, and the end of the manual syringe 3 near the injection needle is also provided with a protective pen cap.

[0040] The entire process of using the intelligent electronic dosage-adjustable injection pen, from fixing the manual syringe 3 (clamping sleeve 2 + second cylinder 9 + locking block 91), adjusting the dosage (motor 71 + belt drive + internal gear sleeve 74), to the final injection (first cylinder 6 + pressing block 61), is triggered automatically by a simple button operation (such as motor button 8), eliminating the need for complex manual steps. This one-button triggering, multi-stage automatic linkage design significantly reduces operational complexity, making it especially suitable for elderly people with limited dexterity or patients with chronic diseases, demonstrating intelligent adaptation to the user's operational capabilities.

[0041] In this embodiment, when using the intelligent electronic dosage adjustment injection pen, the manual syringe 3 is first slidably fitted into one end of the support cylinder 1 via the retainer 2. Simultaneously, the adjustment knob sleeve 31 at the end of the manual syringe 3 engages with the internal gear sleeve 74, and the injection button 33 is inserted into the positioning hole 51 in the middle of the support plate 5. Immediately afterwards, the second cylinder 9 on the support cylinder 1 is activated, causing the locking block 91 to move. The arc-shaped groove on the locking block 91 fits tightly against the outer wall of the manual syringe 3, fixing the manual syringe 3 inside the support cylinder 1. The handle 11 facilitates gripping the device.

[0042] The reading mechanism 4 then aligns with the display mark 32 on the manual syringe 3 to obtain the required injection dosage information, which is then spoken aloud. Pressing the motor button 8 activates the motor 71 within the mounting slot 7. The output shaft of the motor 71 drives the pulley 72 to rotate. Since a belt 73 is fitted onto the pulley 72 and the internal gear sleeve 74, and the slots 75 on both can hold the belt 73, the pulley 72 drives the internal gear sleeve 74 to rotate via the belt 73. The internal gear sleeve 74 engages with the adjustment knob sleeve 31 on the manual syringe 3, thereby driving the adjustment knob sleeve 31 to rotate, achieving automatic dosage adjustment. The internal gear sleeve 74 rotates within the rotation slot 52 of the support plate 5 via the rotating block 76, ensuring rotational stability.

[0043] After the dosage adjustment is completed, the reading mechanism 4 can be used to read the number displayed on the display label 32 in real time, thereby quickly determining the amount injected by the manual syringe 3. Next, the first cylinder 6 is activated, and its piston rod drives the pressing block 61 to move within the positioning hole 51 of the support plate 5. The pressing block 61 presses against the injection button 33 of the manual syringe 3, pushing the injection button 33 to open and completing the injection operation.

[0044] When it is necessary to remove the manual syringe 3, the second cylinder 9 drives the locking block 91 to reset, releasing its fixation, and the manual syringe 3 can be taken out from the sleeve 2.

[0045] The preferred embodiments of the present invention described above are merely illustrative of the invention. These preferred embodiments do not exhaustively describe all details, nor do they limit the invention to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of the invention, thereby enabling those skilled in the art to better understand and utilize the invention.
