Description

Technical Field

[0001] The present application relates to the technical field of medical equipment management, and in particular to a date identification plate for an oxygen humidifier bottle. Background Art

[0002] In medical care scenarios, oxygen humidifier bottles are core equipment for respiratory care, and their replacement cycle directly affects the patient's infection risk and treatment safety. Currently, date management of oxygen humidifier bottles generally relies on manual handwritten labels or simple paper labels, which have the following core pain points:

[0003] 1. Risk of manual calculation error

[0004] The existing method requires medical staff to manually calculate "activation date + replacement cycle = expiration date." However, due to the high workload and complex tasks in medical settings, date calculation errors are prone to occur (e.g., miscalculating a 7-day cycle as 8 days). Expired humidifier bottles directly increase medical risks such as nosocomial infections and equipment failure, threatening patient safety.

[0005] 2. Lack of proactive intelligent reminders

[0006] Traditional signage lacks automatic reminders and relies on manual memory and regular inspections. However, management loopholes exist during night shifts and shift handovers in medical environments, making humidifier bottle replacements easily overlooked. The potential risks of overuse are difficult to avoid, potentially leading to medical accidents.

[0007] 3. Lack of full life cycle data traceability

[0008] Manually recorded replacement information is scattered across paper ledgers or fragmented systems, making it impossible to link unique device identification files (such as humidifier bottle IDs) to form a comprehensive data chain. When tracing a device's activation time, replacement history, and expiration status, query efficiency is extremely low, failing to meet the rigid "traceability" requirements of the Medical Quality Management Measures.

[0009] 4. Insufficient dynamic adjustment capabilities

[0010] If the replacement cycle needs to be temporarily shortened due to an equipment anomaly (such as a damaged humidification membrane), the existing label cannot automatically associate the updated expiration time with the reminder threshold, and manual recalculation and rewriting of the label are still required. This operation is cumbersome and prone to new human errors, reducing the efficiency of abnormal handling. Summary of the Invention

[0011] The present application aims to solve one of the technical problems in the related art at least to a certain extent.

[0012] To this end, one of the purposes of this application is to provide a date identification plate for oxygen humidification bottles, which integrates three-link time calculation and automatically associates activation, cycle, and expiration time to replace manual prevention of overdue periods; multi-level sound and light + remote reminders cover early warnings and strong reminders to reduce omissions; data tracing associates device ID and HIS for full process checking; automatic recalculation and update in case of abnormalities to improve handling efficiency.

[0013] To achieve the above-mentioned purpose, the first embodiment of the present application proposes an oxygen humidification bottle date identification plate, including a device status display body, a three-link time display module, a control processing unit, an intelligent reminder module and a data tracing module, wherein the device status display body is a disc-shaped physical carrier, a device status identification area is provided on the surface, and a preset display area is configured for integrating the intelligent module; the three-link time display module is embedded in the preset display area, and includes three associated time interaction sub-areas, namely: activation time display area: an interactive unit for inputting / displaying the device activation date; replacement cycle display area: an interactive unit for inputting / displaying the device replacement cycle; expiration time display area: an output unit for automatically associating and calculating and displaying the expiration date; the control processing unit is electrically connected to the three-link time display module, serving as the core operation and control center, and has: a linkage calculation submodule: based on the date input in the activation time display area, combined with the cycle parameters of the replacement cycle display area, automatically derives the expiration time and synchronizes it to the expiration time time display area; logical scheduling submodule: associates the intelligent reminder module with the data tracing module to realize multi-module collaborative triggering; the intelligent reminder module is communicated with the control processing unit, configured with a preset time threshold ("1 day before the expiration time" is the replacement reminder threshold), including: an audio and light alarm unit: integrated in the edge of the device status display body, outputs flashing lights and buzzer alarms when triggered; a remote push unit: pushes reminder information to the medical terminal through a wireless communication module; the data tracing module and the control processing unit have two-way data interaction, including: an operation record submodule: records the full process timestamps and parameters of "time setting, reminder triggering, and replacement operations"; a full-cycle association submodule: binds the operation record to the device's unique file (humidifier bottle ID), supports historical data query, export and overdue tracing; inputs basic parameters through the three-linkage time display module, the control processing unit drives the linkage calculation and intelligent reminder, and the data tracing module simultaneously records the full life cycle data to realize the closed-loop management of "input-calculation-reminder-tracing".

[0014] The date identification plate of the oxygen humidifier bottle in the embodiment of the present application integrates three-link time calculation, automatically associates activation, cycle, and expiration time, and replaces manual prevention of overdue period; multi-level sound and light + remote reminders cover early warning and strong reminders to reduce omissions; data tracing associates device ID and HIS for full process checking; automatic recalculation and update in case of abnormality to improve handling efficiency.

[0015] In addition, the date identification plate for the oxygen humidification bottle proposed in the present application may also have the following additional technical features:

[0016] In one embodiment of the present application, the three sub-areas of the three-linked time display module are touch-sensitive interactive screens, which support medical staff to input time parameters by clicking / sliding, and the content of the expiration time display area is automatically generated only by the linkage calculation sub-module, and manual modification is prohibited.

[0017] In one embodiment of the present application, the preset time threshold of the intelligent reminder module supports multi-level configuration: including "first-level threshold (on the day of expiration, triggering sound and light alarm + highest priority push)" and "second-level threshold (N days before expiration, triggering regular push)", and the threshold parameters can be modified by the control processing unit.

[0018] In one embodiment of the present application, the full-cycle association submodule of the data tracing module supports docking with the hospital HIS equipment management platform, and associates the entire process data of equipment procurement, calibration, and scrapping through unique equipment codes to achieve cross-system data tracing.

[0019] In one embodiment of the present application, a wireless communication module is also included, which is integrated with the control processing unit and adopts the Wi-Fi protocol to remotely push reminder information and synchronize traceability data to the cloud server.

[0020] In one embodiment of the present application, the preset display area of ​​the device status display body adopts a translucent anti-scratch touch screen with a built-in pressure sensor, which can identify the pressing operation of medical staff (such as long press to trigger data export and short press to confirm time setting).

[0021] In one embodiment of the present application, the linkage calculation submodule supports dynamic correction of the cycle: when the parameters in the replacement cycle display area are manually adjusted (such as shortening the cycle due to equipment abnormality), the expiration time is automatically recalculated and the intelligent reminder module is triggered to update the reminder threshold.

[0022] The advantages of this application compared with the existing technology are:

[0023] (1) The three-linked time display module and the linked calculation submodule automatically associate the "activation-cycle-expiration" time, replacing manual calculation to ensure the accuracy of the expiration time and avoid the risk of overuse from the source.

[0024] (2) Multi-level intelligent reminders (sound and light + remote push) cover the "early warning-due strong reminder" scenario, filling the gaps in human memory. Especially during high-risk periods such as night shifts and shift handovers, the system's active push can reduce the probability of medical omissions.

[0025] (3) The data traceability module links the unique device ID with the hospital HIS system, forming a data chain for the entire process of "purchase-activation-replacement-scrap". Managers can trace the historical operation of any humidifier bottle (such as whether it has expired and the record of previous replacements), meeting the rigid "traceability" requirements of the "Medical Quality Management Measures".

[0026] (4) When an equipment anomaly requires adjustment of the replacement cycle, the linkage calculation submodule automatically recalculates the expiration time and updates the reminder threshold without manual intervention, thereby improving the efficiency of abnormal handling.

[0039] The embodiments of the present application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application and are not to be construed as limiting the present application. On the contrary, the embodiments of the present application include all variations, modifications, and equivalents that fall within the spirit and scope of the appended claims.

[0040] The following describes the date identification plate of the oxygen humidifier bottle according to the embodiment of the present application with reference to the accompanying drawings.

[0041] like Figures 1-9 As shown, the date identification plate of the oxygen humidifier bottle in the embodiment of the present application can realize the closed-loop management of "input-calculation-reminder-traceability", effectively solving the problems of manual errors, missing reminders, and traceability difficulties in the existing date management of oxygen humidifier bottles.

[0042] Example 1: Introduction to each component

[0043] (1) Device status display main body 1

[0044] The device status display body 1 is a disc-shaped physical carrier made of ABS plastic. Its surface features a device status identification area, which is silk-screened with text such as "Oxygen Humidifier Bottle Status," "Standby," and "In Use," along with an arrow indicator, clearly displaying the current status of the humidifier bottle.

[0045] The surface of the device's status display unit 1 features a pre-set display area 11 for integrating the intelligent module. This area utilizes a translucent, scratch-resistant touchscreen. This touchscreen has a built-in pressure sensor with a sensitivity of 10g, enabling accurate recognition of medical personnel's pressure inputs. For example, a 2-second long press triggers data export, while a 0.5-second short press confirms time settings.

[0046] An audio-visual alarm unit 41 is integrated at the edge of the device status display body 1, specifically a ring-distributed group of 12 RGBLED lights and a buzzer. The frequency of the buzzer is 2kHz and the loudness is 85dB, which is convenient for issuing obvious alarm signals in different environments.

[0047] (2) Three-link time display module 2

[0048] The three-linked time display module 2 is embedded in the preset display area 11, and its three sub-areas are all touch-sensitive interactive screens, which support medical staff to input time parameters by clicking, sliding, etc.

[0049] The activation time display area 21 is an interactive unit for inputting / displaying the activation date of the device. Medical staff can select or enter a specific activation date in this area through touch operation. The format is YYYY-MM-DD. After the input is completed, the area will clearly display the set activation date.

[0050] The replacement cycle display area 22 is an interactive unit for inputting / displaying the device replacement cycle. The default replacement cycle is 7 days. Medical staff can adjust the replacement cycle through touch operation according to actual conditions. The adjustment range is 1-30 days. After adjustment, the area will display the new replacement cycle in real time.

[0051] The expiration time display area 23 is an output unit that automatically calculates and displays the expiration date. Its content is automatically generated by the linkage calculation submodule 31 and cannot be manually modified. This area will display the calculated expiration date in a clear font, also in the format of YYYY-MM-DD.

[0052] (3) Control processing unit 3

[0053] The control processing unit 3 is electrically connected to the three-link time display module 2 via PCB circuitry, serving as the core computing and control hub of the entire device. It utilizes an STM32F407 single-chip microcontroller with a main frequency of 168MHz, 1MB of memory, and an integrated real-time clock module (RTC), achieving a time accuracy of ±5ppm.

[0054] The linkage calculation submodule 31 automatically derives the expiration time based on the date entered in the activation time display area 21 and the cycle parameters in the replacement cycle display area 22 using a Java Calendar class date algorithm. The result is then synchronized to the expiration time display area 23. This submodule also supports dynamic cycle correction. If the parameters in the replacement cycle display area 22 are manually adjusted, such as when the cycle is shortened due to a device anomaly, the expiration time is immediately recalculated, triggering the intelligent reminder module 4 to update the reminder threshold.

[0055] The logic scheduling submodule 32 links the intelligent reminder module 4 with the data tracing module 5 to achieve multi-module coordinated triggering. It presets time threshold rules and calibrates the system time in real time through the RTC module. When the system time reaches the preset threshold, it drives the intelligent reminder module 4 to perform the corresponding reminder operation and triggers the data tracing module 5 to record the reminder event.

[0056] (IV) Intelligent reminder module 4

[0057] The intelligent reminder module 4 and the control processing unit 3 are connected in communication via wireless communication, and are configured with a preset time threshold, wherein "1 day before the expiration time" is the replacement reminder threshold, and the preset time threshold supports multi-level configuration.

[0058] The first-level threshold is the day of the expiration date. When this threshold is reached, the sound and light alarm unit 41 and the highest priority push notification are triggered. The RGB LED light group of the sound and light alarm unit 41 will flash red quickly with a flashing period of 0.5 seconds, and the buzzer will sound continuously for 2 seconds with a 1-second interval. The remote push notification unit 42 will push the highest priority reminder information to the medical terminal, which will be displayed as a red pop-up window on the nurse station terminal and the responsible nurse's PDA.

[0059] The secondary threshold is N days before expiration (N can be set according to actual needs). When this threshold is reached, a regular push notification is triggered. The remote push unit 42 sends a regular priority reminder message to the medical terminal, which is displayed as a yellow reminder. At this time, the RGB LED light group of the sound and light alarm unit 41 flashes slowly in blue with a flashing cycle of 2 seconds, and the buzzer beeps once every 5 seconds for 0.5 seconds.

[0060] The threshold parameters can be modified through the control processing unit 3, and can be set locally through the three-link time display module 2, or can be modified remotely through the hospital management system.

[0061] (V) Data tracing module 5

[0062] The data tracing module 5 realizes two-way data interaction with the control processing unit 3, and can record and manage the data of the entire life cycle of the equipment.

[0063] The operation record submodule 51 records the timestamps and parameters of the entire process of "time setting, reminder triggering, and change operation" with timestamps accurate to the second. This data will be stored in the local 8GB EEPROM flash memory and synchronized to the hospital cloud server after encryption.

[0064] The full-cycle association submodule 52 binds operation records to the device's unique profile (humidifier bottle ID), which can be set on the humidifier bottle via a QR code or RFID tag. This submodule supports integration with the hospital's HIS equipment management platform, linking data from the entire equipment procurement, calibration, and retirement process through unique device codes, enabling cross-system data traceability and supporting historical data query, export, and overdue data tracing.

[0065] (6) Wireless communication module 6

[0066] The wireless communication module 6 is integrated with the control processing unit 3 and uses the Wi-Fi protocol. Specifically, it is an ESP32 Wi-Fi module that supports the 802.11ac protocol and has a transmission rate of 433Mbps. It is pre-programmed with the SSID and password of the hospital intranet and communicates with the nurse station terminal server via the MQTT protocol. It is used to remotely push reminder information and synchronize traceability data to the cloud server.

[0067] Example 2: Connection relationship between various parts

[0068] The preset display area 11 of the device status display body 1 provides an installation location for the three-linked time display module 2, which is embedded in it. The control processing unit 3 is electrically connected to the three-linked time display module 2 through the PCB board circuit, receives its input parameters and processes them.

[0069] The intelligent reminder module 4 is connected to the control processing unit 3 via wireless communication, receiving instructions from the control processing unit 3 and executing corresponding reminder operations. The data tracing module 5 interacts with the control processing unit 3 in a two-way manner, receiving operation data sent by the control processing unit 3 and providing feedback on tracing information.

[0070] The wireless communication module 6 is integrated into the control processing unit 3, providing communication support for the remote push unit 42 and the data tracing module 5, and realizing data transmission with the medical terminal, cloud server and hospital HIS equipment management platform.

[0071] Example 3: Workflow

[0072] 1. Parameter input stage: Medical staff short press the activation time display area 21 of the three-link time display module 2 to pop up the date selector, select or enter the activation date of the humidifier bottle, and after confirmation, the data is transmitted to the control processing unit 3; similarly, short press the replacement cycle display area 22 to enter or adjust the replacement cycle, and the data is also transmitted to the control processing unit 3.

[0073] 2. Calculation stage: The linkage calculation submodule 31 of the control processing unit 3 automatically derives the expiration time through a date algorithm based on the received activation date and replacement cycle, and synchronizes the result to the expiration time display area 23.

[0074] 3. Reminder stage: The logic scheduling submodule 32 of the control processing unit 3 calibrates the system time in real time. When the system time reaches the secondary threshold (N days before expiration), the remote push unit 42 of the intelligent reminder module 4 is triggered to send a regular push message, and the sound and light alarm unit 41 performs a corresponding sound and light prompt; when the first threshold is reached (the day of expiration), the remote push unit 42 is triggered to send the highest priority push message, and the sound and light alarm unit 41 performs a stronger sound and light alarm.

[0075] 4. Tracing stage: During the entire process, the operation record submodule 51 of the data tracing module 5 records the timestamps and parameters of each operation in real time, and stores and synchronizes them to the cloud; the full-cycle association submodule 52 binds these records to the humidification bottle ID and connects to the hospital HIS equipment management platform to form a full-process data chain for subsequent query, export and tracing.

[0076] 5. Dynamic cycle correction stage: If the replacement cycle needs to be adjusted due to equipment abnormality or other reasons, the medical staff will manually adjust it in the replacement cycle display area 22. The linkage calculation submodule 31 will automatically recalculate the expiration time and trigger the intelligent reminder module 4 to update the reminder threshold to ensure that the reminder information matches the new cycle.

[0077] It should be noted that the control method of the present application can be automatically controlled by a controller, and the control method of the controller can be implemented by simple programming by technicians in this field, which is common knowledge in this field. In addition, the present application is mainly used to protect mechanical structures, so the control method and circuit connection are no longer explained in detail in this application.

[0078] In summary, the date identification plate of the oxygen humidifier bottle in the embodiment of the present application integrates three-link time calculation, automatically associates activation, cycle, and expiration time, and replaces manual prevention of overdue; multi-level sound and light + remote reminders cover early warning and strong reminders to reduce omissions; data tracing associates device ID and HIS for full process checking; automatic recalculation and update in case of abnormality to improve handling efficiency.
