Description
Technical Field
[0001] This utility model relates to the field of timer technology, specifically to a cyclic timer reminder. Background Technology
[0002] Timers (or reminders) are common time management tools that play an important role in many scenarios, including daily life, work, study, clinical settings, and laboratories. For example, patients undergoing ICL surgery in ophthalmology need to use multiple eye drops simultaneously or at set times during the pre-operative or post-operative observation period, and generally require an automatic eye drop reminder. Patients with eye diseases requiring long-term treatment or regular medication, such as those before and after ophthalmic surgery, glaucoma, or dry eye syndrome, have an even more urgent need for automatic eye drop reminders.

Figure 1 As shown, users manually set the time using the buttons on the interface to achieve the timed reminder function. However, most common timers (or reminders) on the market have many buttons, cumbersome interfaces, and require patients to manually input the timing, which is extremely inconvenient for patients with blurred vision after ophthalmological surgery. In addition, existing timers (or reminders) generally only have a single countdown function, while postoperative ophthalmological patients need to use eye drops continuously at fixed times, and the single countdown function can no longer meet the actual needs of ophthalmological patients.
[0004] Based on this, this application proposes a cyclic timing reminder that can achieve multiple cycles of timing with only simple operation, thereby meeting the actual use needs of patients after ophthalmic surgery and improving the convenience and satisfaction of patients. Utility Model Content

[0039] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0040] Patients undergoing ICL surgery in ophthalmology who need to use multiple eye drops simultaneously for a short period before or during postoperative observation generally require an automatic eye drop reminder to reduce the occurrence of delayed or missed use of eye drops, thereby ensuring the timeliness and accuracy of eye drop use. For patients with eye diseases requiring long-term treatment or regular medication, such as those before and after ophthalmic surgery, glaucoma, and dry eye syndrome, the need for automatic eye drop reminders is even more urgent.
[0041] Clinically used timers typically combine multiple functions such as timing, alarm clock, stopwatch, and countdown timer. While they offer many features, they also have the following drawbacks:
[0042] 1) Cumbersome User Interface. Most commercially available timers (or reminders) have numerous buttons and complex user interfaces to achieve a wide range of functions. However, in clinical ophthalmology, timers are generally used by post-operative ophthalmic patients. These patients often experience blurred vision due to factors such as surgical incisions, corneal edema, and increased intraocular pressure, which can last for a prolonged period. A timer with a cumbersome interface is actually detrimental to post-operative vision problems. Only the simplest and most direct timing function can truly meet the needs of post-operative ophthalmic patients.
[0043] 2) Manual input of timing is required. Existing timers require manual input of timing. However, the interval between eye drops after ophthalmological surgery is generally fixed at 5 minutes / 10 minutes / 15 minutes. A timer requiring manual input of timing requires continuous setting of the timing function. However, elderly patients constitute a large proportion of ophthalmological patients, and for elderly people using eye drops at home, the convenience of manually adjusting and inputting timing has many drawbacks.
[0044] 3) Single-use countdown function only. Currently available timers in clinical settings only offer a single-use countdown timer. However, postoperative ophthalmic patients need to use eye drops continuously at fixed intervals, and a single-use countdown function cannot meet their practical needs.
[0045] In addition, most timers on the market are mounted on a stand or placed horizontally. During clinical observation, the size of the ward space is limited, and the conventional placement of existing timers has limitations in terms of placement location.
[0046] Based on this, the embodiments of this application provide a cyclic timing reminder, which solves the problem that existing timers cannot achieve multiple cyclic timing functions with only a single setting, greatly meeting the actual use needs of patients after ophthalmic surgery and improving patient convenience and satisfaction.
[0047] The technical solution in this application is to solve the above-mentioned technical problems, and the general idea is as follows:
[0048] To address the limitation of existing cyclic timers that cannot achieve multiple cyclic timing functions with a single setting, this application's cyclic timer is equipped with a cyclic working timing controller. This controller provides timing clock pulses to the timer, enabling it to continuously provide cyclic reminders at fixed time points. Furthermore, to resolve the issue of complex user interfaces in existing timers, which are unfriendly to ophthalmic surgery patients, the user interface has been simplified. Specifically, 5-minute / 10-minute timer setting buttons have been added, and the timer setting operation is announced via voice prompts for easy operation and confirmation by ophthalmic patients. Moreover, to address the issue of convenient timer placement, this application's timer features a lanyard and a three-dimensional stand on the back of the timer casing. Further, a drawer-type storage box is integrated into the three-dimensional stand, ensuring not only the stability and convenience of the timer when placed but also enhancing its storage function. This allows patients to conveniently store eye drops and other related items while using the timer.
[0049] It should be noted that the cyclic timing reminder proposed in this application is not limited to use in clinical ophthalmology scenarios where patients use eye drops at set times. It can be used in various scenarios such as daily life, work and study, entertainment, and laboratories. For ease of explanation and illustration, the following embodiments of this application will use the timing of eye drop use as an example to illustrate the composition structure and usage principle of the cyclic timing reminder in each embodiment of this application. However, this specific example is not intended to limit the technical solution of this application.
[0050] To better understand the above technical solution, the following will refer to the appendix to the instruction manual. Figures 2-8 The specific implementation methods are described in detail below for the above technical solutions.
[0051] Example 1:
[0052] See Figure 2 , 3 5, and Figure 6 This embodiment proposes a cyclic timer reminder, comprising: a cyclic control module 6, a timing module 7, a time setting module 8, a display module 9, a button module 10, a prompting module 11, and a power module 12. All of the above modules are integrated within or on the housing 1 of the cyclic timer reminder. The cyclic control module 6, timing module 7, time setting module 8, prompting module 11, and power module 12 are all integrated within the housing 1. The circuitry of the display module 9 is disposed within the housing 1, and the display is embedded in the housing 1. The button module 10 is disposed on the housing 1 through a through-hole. Specifically:
[0053] The loop control module 6, electrically connected to the timing module 7, provides cyclic clock pulses to the timing module 7, thereby controlling the cyclic timing of the timer. The loop control module 6 mainly includes a cyclic timing controller. For example... Figure 4 The diagram shows the circuit schematic of a cyclic timing controller. After being stepped down by capacitor C2 and bleeder resistor R3, the voltage is rectified by bridge rectifier IC2 and regulated by VD2 to obtain a DC voltage of approximately 12V, which powers IC1 and other circuits. IC1 is a 14-bit binary counter-divider integrated circuit. A clock oscillator of a specific frequency is formed by R1, R2, C1, and the internal circuitry of IC1, providing clock pulses for IC1's timing.
[0054] When the circuit is powered on, it first enters a waiting period during the device's operation interval. Internally, IC1 delays the time by counting and dividing the clock pulses. When the timeout period (e.g., 5 or 10 minutes) is reached, Q14 of IC1 outputs a high level, turning on transistor V, energizing relay KA, and driving the controlled device (the timer in this embodiment) to start working. At this time, IC1 starts timing the device's operation again. When the timeout period is reached (e.g., the interval between cycles is 1 or 2 seconds), Q14 of IC1 returns to a low level, turning off V, and the device stops working. IC1 then automatically resets and starts the next timing cycle, allowing the device to operate in a timed cycle according to the set time. VL is a working indicator light; it remains lit when the circuit is working normally.
[0055] The timing module 7 is used for the countdown of the cyclic timing reminder. In this embodiment, preferably, the timing module 7 includes a subtraction circuit composed of two cascaded 74LS192 IC1 and IC2, where IC1 is the high-order bit and IC2 is the low-order bit. Its data input terminals D3D2D1D0 are connected to the output terminals Q3Q2Q1Q0 of IC3 and IC4, respectively. That is, when the LD of IC1 and IC2 is low, their outputs are the same as the data at the data input terminals.
[0056] The time setting module 8, electrically connected to the timing module 7, is used to set the countdown time for the cyclic timer reminder. In this embodiment, preferably, the time setting module 8 consists of two synchronous decimal up / down counters 74LS192 IC3 and IC4, with IC3 setting the high-order digit and IC4 setting the low-order digit. Both 74LS192s are in decimal addition mode. The corresponding spring buttons S1 and S2 in the button module 10 act as the addition pulses. For example, when setting the total time to 8 minutes, S1 needs to be pressed zero times and S2 eight times. At this point, the outputs Q3Q2Q1Q0 of the two 74LS192 IC3 and IC4 are 0 and 8 in decimal, respectively. When the total time is set to 12 minutes, press S1 once and S2 twice. At this point, the outputs Q3Q2Q1Q0 of the two 74LS192 IC3 and IC4 are 1 and 2 in decimal, respectively. When the total time is set to 15 minutes, press S1 once and S2 five times. At this point, the outputs Q3Q2Q1Q0 of the two 74LS192 IC3 and IC4 are 1 and 5 in decimal, respectively.
[0057] The display module 9, electrically connected to the timing module 7, the time setting module 8, and the power module 12, is used to display the time status, timing status, and the power status of the timer, etc.
[0058] In this embodiment, the display module 9 includes a display circuit, wherein a digital display circuit is composed of several display decoders 74LS48 and a common cathode LED display to display the time status, and / or a seven-segment display circuit is composed of a seven-segment LED display to display the instantaneous and intermediate timing results output by the timing circuit. The timing signal output by the timing module 7 is decoded by the decoding display circuit and displayed by the seven-segment LED display. In addition, the display module 9 also displays the power level of the power supply.
[0059] In one embodiment, preferably, the display module 9 further includes a liquid crystal display (LCD). The LCD is divided into three sections, which, from left to right on the loop timer, are: section 1 displays the regular time (24-hour format, accurate to the second); section 2 displays the countdown count (i.e., the number of times the countdown loop will play); and section 3 displays the battery level (in percentage). See [link to details] for further information. Figure 5 .
[0060] The button module 10 is electrically connected to the time setting module 8 and the cycle control module 6, and is used for setting the duration and number of countdowns, controlling the start and stop status of the timer, and controlling the volume of the timer audio.
[0061] The button module 10 includes: a duration setting button for selecting the countdown duration (e.g., an 8-minute countdown setting button and a 12-minute countdown setting button), and a countdown count setting button (e.g., a countdown count increment "+" button and a countdown count decrement "-" button); a start / stop control button for controlling the timer's direct setting, resetting, starting, and pausing functions; and an audio control button for setting the timer's audio volume. As shown in the figure, considering the convenience of button settings and the simplicity of the user interface, a preferred embodiment of this embodiment is that, based on the generally fixed interval of eye drops use after ophthalmological surgery (5min / 10min / 15min), the timer has two duration setting buttons: 5min and 10min. After pressing the 5min / 10min button once, the user directly sets the 5min / 10min countdown. The "+" / "-" buttons are for setting the countdown count, adjusting the desired number of countdown cycles. For example, to set a 5-cycle 5-minute countdown, after pressing the 5min duration setting button once, the "+" button is pressed 5 times. For usage needs beyond the fixed 5min / 10min timeout, press and hold the "Start / Pause" button for more than 3 seconds, then press the "+" / "-" button to set the desired duration. The "△" and "▽" buttons are audio control buttons used to adjust the volume. For detailed settings of the various buttons in button module 10, please refer to [link to documentation]. Figure 3 and Figure 5 .
[0062] After setting the desired countdown time and number of cycles, press the "Start / Pause" button to begin the timer. To pause the timer, simply press the "Start / Pause" button again. The timer will automatically shut off after the countdown ends; to restart it, simply press any button.
[0063] The prompt module 11 is electrically connected to the timing module 7 and the time setting module 8, and is used for countdown alarm reminders and time setting announcements. The prompt module 11 includes an alarm reminder unit and a setting announcement unit. The setting announcement unit announces the countdown duration when setting a 5-minute countdown, a 10-minute countdown, and the number of 5-minute and 10-minute countdowns. The alarm reminder unit provides an alarm after the countdown ends, reminding the patient that the time has elapsed and medication should be taken immediately. In a preferred embodiment, an LM555 multivibrator is used. When its terminal RD is low, the 555 output is cleared, and there is no oscillation pulse output; when RD is high, the 555 output pulse causes the speaker to emit a high-low-high-low sound signal. The frequency of the sound signal can be set by adjusting the resistance value of the resistor connected in parallel with the LM555. In a preferred embodiment, the prompt module 11 is connected to a sound hole on the back of the housing 1 for playing countdown alarm reminders and time setting announcements.
[0064] Power module 12, electrically connected to all the aforementioned modules, is used to supply power to all modules or circuits of the entire timer. Specifically, power module 12 includes a battery management unit, a battery unit, and a charging interface unit. The battery unit supplies power to all modules of the entire cycle timer reminder, the battery management unit manages and controls the battery unit's power level, and the charging interface unit is used to charge the battery unit. In a preferred embodiment, the charging interface unit is a Type-C interface located on the side of the cycle timer reminder, and the charging interface unit is connected to an external 220V power supply.
[0065] Example 2:
[0066] To ensure the stability and convenience of the aforementioned cyclic timer reminder during placement, this embodiment, based on Embodiment 1, includes a placement component 2 on its outer casing 1. This placement component 2 comprises a three-dimensional support 21 and a hanging rope 22.
[0067] In a preferred embodiment, a three-dimensional support 21 is designed on the lower back of the housing 1 of the cyclic timer reminder, which is just large enough to accommodate the support slot 5. The upper end of the three-dimensional support 21 is rotatably connected to a rotating shaft in the support slot 5, and the lower end can be rotated and adjusted within a certain angle A around the upper rotating shaft to open or close, adapting to different placement needs. The optimal adjustable angle of the three-dimensional support 21 is A = 75°, making the viewing angle more comfortable and convenient for the patient. For details, please refer to [reference needed]. Figure 7 .
[0068] The lanyard 22 is located on the upper back of the casing 1 of the cycle timer reminder. Specifically, two holes 13, spaced 3.5cm apart and 6mm in diameter, are pre-drilled on the upper back, allowing the patient to thread the lanyard and hang it freely in a clearly visible area. The DIY threading allows for easy adjustment of the lanyard length, making it more convenient and practical for clinical use. See details for further information. Figure 6 .
[0069] Example 3:
[0070] To ensure the convenience of the aforementioned cyclic timer reminder for patients, and the convenience of placing eye drops or other medications, the lanyard 22, and other supporting items, this embodiment, based on embodiment 2, includes a storage box 3. For details, please refer to... Figure 8 The storage box 3 includes a first storage box 31 and a second storage box 32. The first storage box 31 is a drawer-type storage box 3, with one end located at the lower end of the three-dimensional support 21 near the outer shell 1 of the cycle timer reminder, and the other end slidably connected to a storage slot 4 opened on the outer shell 1 of the cycle timer reminder. The opening of the storage slot 4 is adapted to the travel path of the drawer-type storage box 3 when it is stored, as well as the size of the drawer-type storage box 3, so that when the three-dimensional support 21 is retracted around its upper rotation axis, the three-dimensional support 21 can be just retracted into the support slot 5, and the drawer-type first storage box 31 can be just hidden in the storage slot 4.
[0071] The second storage box 32 includes a hollow cavity inside the three-dimensional support 21. Furthermore, a storage cover is also provided on the outer shell 1. The storage cover is opened or closed by engaging with the hollow cavity through a snap-fit structure, thus forming the second storage box 32.

[0074] 2. This application proposes a cyclic timer reminder device, which features buttons for setting the countdown duration and number of countdowns, allowing users to easily set multiple countdowns at once, making the timer setting operation simpler and more convenient.
