Technical Field

[0001] The invention belongs to the technical field of printers, in particular to a medical timing printer. Background Art

[0002] At present, in the infusion process, the conventional way to record the drug label information on the infusion bottle is for the nurse to manually write the time and name. However, this manual handwriting method has many disadvantages. On the one hand, the handwriting process is time-consuming. Under the busy work rhythm of the hospital, especially during the period when patients are concentrated in the infusion, it will greatly reduce the efficiency of nursing work and affect the timely care and attention of the nurses to the patients. On the other hand, handwriting is prone to sloppy handwriting, which may make the information difficult to recognize, causing confusion in the subsequent treatment process, and posing a potential risk to the patient's treatment safety. With the development of science and technology, label printers have gradually been applied to various fields, and are also used in the medical industry to a certain extent.

[0003] Although existing label printers can realize the printing function, and people can quickly edit the content in the fixed template on the mobile phone, they still need to write real-time information, including contact time, etc. The operation of real-time information entry is cumbersome and difficult to meet the needs of instant recording.

[0024] The following is a further detailed description of the embodiments of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0025] As attached Figure 1 , Attachment Figure 2 and attached Figure 3 As shown: The present invention provides a medical timing printer, comprising a housing 1, an input module, a printing module and a power module;

[0026] The housing 1 includes a fixed housing 101, a disassembly cover 102 and a base 103. A paper bin 6 is fixed to the inner wall of the base 103. The fixed housing 101 and the disassembly cover 102 are both installed above the base 103. A paper outlet 15 is provided between the fixed housing 101 and the disassembly cover 102.

[0027] The input module includes a touch screen 102a and a main control board 8. The touch screen 102a is integrated in the fixed shell 101. The main control board 8 integrates a central processing unit, a printing control unit, a human-computer interaction interface, a clock chip, a communication module and a power management module.

[0028] The printing module includes a thermal print head 4, a transmission frame 5 and a label paper 7. The label paper 7 is assembled in a paper bin 6. The thermal print head 4 and the transmission frame 5 are fixed in a base 103, and both the thermal print head 4 and the transmission frame 5 are located below a paper outlet 15. The transmission frame 5 is driven by a stepper motor 28BYJ-48: the main control board 8 outputs a 4-phase 8-beat control signal of 5.625° / step; the photoelectric sensor 16 monitors the position of the label paper 7 in real time; the transmitting end of the photoelectric sensor 16 adopts a 940nm infrared LED (IF=20mA); the receiving end adopts a phototransistor (VCEsat=0.4V); when a paper shortage is detected, a hardware interrupt (EXT I9_5) is triggered.

[0029] The power module includes a battery pack 9, a power control board 2 and a trigger switch 3. The trigger switch 3 is mounted on the surface of the fixed shell 101, and the trigger switch 3 is electrically connected to the power control board 2. The battery pack 9 and the power control board 2 are both electrically connected to the main control board 8.

[0030] The nursing staff performs operations through the touch screen 102a: the central processor (ARMCortex-M7) starts DMA transfer: loads the preset template from the Flash memory (MX25L3206E) to the SDRAM; creates a dynamic data buffer (512 bytes); the clock chip is connected to the I 2 C bus (400kHz rate) transmission timestamp:

[0031] Year / month / day are encoded in BCD (0x20-0x7F); hours, minutes and seconds are in binary complement format; print content is generated.

[0032] The print control unit (FPGAXC6SLX9) performs rasterization processing: converts ASCII characters into 8×16 dot matrix bitmaps; adds anti-tampering watermarks (CRC-16 checksums) to time data; and generates thermal print head drive waveforms (pulse width modulation accuracy 1μs).

[0033] The trigger switch 3 adopts a double-contact redundant design; when the caregiver presses the switch: the first contact is turned on: a wake-up signal (3.3VTTL level) is sent to the power control board 2; the second contact is closed: the MOSFET power supply circuit of the battery pack 9 is activated;

[0034] The power management module performs a power-on self-test:

[0035] Check whether the battery voltage of 3.7V lithium battery is ≥3.3V;

[0036] Check the temperature compensation accuracy of the clock chip (DS3231 SN) (±2ppm);

[0037] Initialize the thermal print head 4 to preheat to a working temperature of 80°C ±5°C.

[0038] A photoelectric sensor 16 is installed on the side wall of the transmission frame 5 . The position of the photoelectric sensor 16 corresponds to the paper bin 6 , and the photoelectric sensor 16 is electrically connected to the main control board 8 .

[0039] A slot 11 is formed at the bottom wall of the base 103 , and a buckle 12 is fixed to the bottom wall of the disassembly cover 102 . The buckle 12 is engaged with the slot 11 , and the disassembly cover 102 is engaged with the base 103 .

[0040] A buckle slot 19 is provided on the paper discharge end surface of the disassembly cover 102 .

[0041] A mounting seat 13 and a positioning seat 14 are fixed to the inner wall of the base 103 . The main control board 8 is fixed to the mounting seat 13 , and the power control board 2 is clamped to the positioning seat 14 .

[0042] A heat-conducting seat 17 is fixedly installed on the inner wall of the fixed shell 101, and the position of the heat-conducting seat 17 corresponds to the thermal print head 4. A plurality of heat-dissipating fins 18 are arranged on the bottom of the heat-conducting seat 17, and a heat-dissipating groove is opened on the rear end surface of the fixed shell 101, and the position of the heat-dissipating groove corresponds to the position of the heat-dissipating fins 18.

[0043] A plurality of anti-skid pads 20 are installed on the bottom surface of the base 103 .

[0044] As can be seen from the above, when the caregiver uses the printer, he presses the trigger switch 3 on the surface of the fixed shell 101 ; when the caregiver presses it, the first contact is first turned on and sends a wake-up signal of 3.3VTTL level to the power control board 2 .

[0045] Then the second contact is closed, activating the MOSFET power supply circuit of the battery pack 9, so that the battery pack 9 starts to supply power to the entire printer system.

[0046] The power management module performs a power-on self-test at this time to detect whether the voltage of the 3.7V lithium battery is ≥3.3V, and to verify whether the temperature compensation accuracy of the clock chip is within the range of ±2ppm. At the same time, it initializes the thermal print head 4 and preheats it to an operating temperature of 80℃±5℃ to ensure that all components of the printer are in normal working condition.

[0047] Data preparation and input:

[0048] The CPU starts a direct memory access (DMA) transfer to load the preset template from the Flash memory (MX25L3206E) to the synchronous dynamic random access memory (SDRAM) and establish a 512-byte dynamic data buffer.

[0049] The clock chip is connected via I 2 C bus transmits timestamp, year / month / day is encoded in BCD, hours, minutes and seconds are encoded in binary complement format, and real-time time data is transmitted to the central processor.

[0050] The nursing staff inputs the name of the executor and other information through the touch screen 102a integrated in the fixed shell 101. The touch signal of the touch screen is converted into an electrical signal and transmitted to the human-machine interface in the main control board 8, which is then parsed into corresponding character information and transmitted to the central processor and stored in the dynamic data buffer.

[0051] The nursing staff installs the label paper 7 in the paper bin 6 on the inner wall of the base 103, ensuring that the axis of the label paper is accurately aligned with the rotation axis of the paper bin. After installation, the front end of the label paper 7 is led out of the paper bin and passes through the specially designed paper guide channel on the transmission frame 5, so that the front end of the label paper is under the thermal print head 4.

[0052] The photoelectric sensor 16 on the side wall of the transmission rack 5 monitors the position of the label paper 7 in real time; when the label paper is installed in place and blocks the light path, the photoelectric sensor 16 detects a signal change and feeds the signal back to the main control board 8. If it is detected that there is no paper, a hardware interrupt is triggered to remind the nursing staff.

[0053] The central processing unit transmits data such as time information and executor's name to the print control unit; the print control unit performs rasterization processing, converts ASCII characters into 8×16 dot matrix bitmaps, adds an anti-tampering watermark (CRC-16 checksum) to the time data, and generates a thermal print head drive waveform (pulse width modulation accuracy 1μs).

[0054] The main control board 8 outputs a 4-phase 8-beat control signal to drive the stepper motor of the transmission frame 5 to rotate, thereby driving the label paper 7 to move forward; the thermal print head 4 heats the label paper 7 according to the driving waveform generated by the print control unit to form text information containing the instant time and the name of the executor, and the printed label paper is delivered from the paper outlet 15 between the fixed shell 101 and the disassembly cover 102.

[0055] Through the touch screen 102a integrated in the fixed shell 101, nursing staff can directly and quickly input information, bid farewell to the cumbersome process of complex editing with the help of external devices, greatly shorten the time of information entry, and significantly improve efficiency in busy medical work. The clock chip in the main control board 8 automatically obtains and records the real-time time, without manual filling, fundamentally avoiding the errors caused by manual time recording, and providing accurate time reference for medical records. The printing control unit converts characters into clear dot matrix bitmaps to make the printed text clear and easy to read; adds tamper-proof watermarks to the time data to ensure that the time information is accurate and complete, prevents tampering, and effectively enhances the credibility of medical records. The trigger switch 3 with double contact redundant design ensures stable power supply startup and reduces the probability of the device being unable to start due to switch failure; the power management module performs a comprehensive power-on self-test, detects the battery, verifies the chip, and preheats the thermal print head 4 to ensure the normal operation of various components of the printer and reduce the interference of equipment failure on medical work. The photoelectric sensor 16 on the side wall of the transmission frame 5 monitors the position of the label paper 7 in real time. Once the lack of paper is detected, a reminder is immediately issued to avoid printing interruption and ensure the smooth progress of printing. The card slot 11 on the bottom wall of the base 103 is cleverly engaged with the card buckle 12 on the bottom wall of the disassembly cover 102, making it convenient to open the disassembly cover to replace label paper or maintain the equipment; the card slot 19 on the paper outlet end of the disassembly cover 102 makes it easy and convenient to open the cover; the mounting seat 13 and the positioning seat 14 on the inner wall of the base 103 firmly install the main control board 8 and the power control board 2, and are convenient for maintenance; the non-slip foot pad 20 on the bottom surface of the base 103 prevents the printer from sliding and ensures safe use. The heat-conducting seat 17 and the heat-dissipating fins 18 on the inner wall of the fixed shell 101, together with the rear heat dissipation slot, efficiently dissipate the heat generated by the thermal print head 4, extend the service life of the print head, and ensure long-term stable operation of the printer.

[0056] When using: Check the printer to ensure that the battery is fully charged and there is enough label paper in the paper compartment. Enter the name and work number of the executor (such as a nurse) and other information on the touch screen of the printer. Place the printer on a treatment cart filled with infusion tubes and medicines and push it to the ward area.

[0057] Go to the patient's bedside, carefully check the patient's identity information, press the printer button, obtain a label printed with the current infusion execution time and executor information, stick the label on the infusion bottle, and perform the infusion operation for the patient; repeat the above steps of checking, printing, labeling, and infusing, and serve other patients in turn.

[0058] If the patient has multiple bottles of liquid, after affixing the label and adding the medicine, press the printer button again to obtain the label. There is no need to re-enter the executor information, and the new label can be directly attached to the subsequent infusion bottle.

[0059] Example 1: Daily infusion peak in a comprehensive hospital

[0060] Preparation stage: Before the peak of infusion, the nurse checks the power of the medical timekeeping printer to ensure that the battery pack 9 is fully charged, and checks the remaining label paper 7 in the paper bin 6. If it is insufficient, it is replaced in time. Then press the trigger switch 3 on the surface of the fixed shell 101. The double contact design ensures stable power startup. The power control board 2 connects the battery pack 9 and the main control board 8. The power management module starts working, detects the battery voltage, verifies the temperature compensation accuracy of the clock chip, and initializes the thermal print head 4 to preheat to the working temperature.

[0061] Information entry: The nurse pushes a cart with a printer to the ward and enters her work number through the touch screen 102a in front of each bed. The human-computer interaction interface transmits the input information to the central processor in the main control board 8, and the clock chip 2 C bus transmits real-time timestamps at a rate of 400kHz.

[0062] Printing execution: After receiving the information, the CPU starts DMA transmission, loads the preset template from the Flash memory (MX25L3206E) to the SDRAM, and establishes a dynamic data buffer. The printing control unit (FPGAXC6SLX9) converts ASCII characters into 8×16 dot matrix bitmaps, adds anti-tampering watermarks (CRC-16 checksums) to the time data, and generates a thermal print head drive waveform (pulse width modulation accuracy 1μs). Driven by the 4-phase 8-beat control signal (5.625° / step) output by the main control board, the stepper motor (28BYJ-48) of the transmission frame 5 drives the label paper 7 to move under the thermal print head 4. The thermal print head heats the label paper according to the drive waveform and prints out a label containing the time and work number.

[0063] The nurse tears off the printed label and accurately posts it on the infusion bottle to complete the labeling of one patient's infusion bottle. According to this process, the operation of 40 patients can be completed quickly in just 20 minutes. It takes 20 minutes to print the labels of 40 patients, which saves 66.7% compared with the traditional mobile phone editing solution (60 minutes), and the nurse's operation path is reduced by 50% (no need to go back and forth between the operating table and the bed).

[0064] Example 2: Emergency Infusion in the Emergency Room of a Children's Hospital

[0065] After receiving the task of providing emergency infusion to 5 children with food poisoning, the nurse quickly found the medical timer printer, pressed the trigger switch 3, and the double contacts quickly connected the power supply. The printer quickly started and completed the self-test to ensure that all components were working properly.

[0066] Quickly input your name on the touch screen 102a, and the photoelectric sensor 16 on the side wall of the transmission rack 5 monitors the position of the label paper 7 in real time. If there is a shortage of paper, it will immediately trigger a hardware interrupt to remind the nurse to replace it.

[0067] The central processor quickly receives the name information and the time information from the clock chip, and the print control unit quickly converts the information into the required format for printing, and drives the thermal print head 4 to print quickly. The stepper motor accurately controls the rotation of the transmission frame 5 to move the label paper quickly.

[0068] The printing of infusion labels for 5 children was completed within 5 minutes. The nurses quickly shuttled between the beds with the labels and accurately attached the labels to the infusion bottles to ensure smooth treatment.

[0069] The emergency infusion labels for 5 children were completed within 5 minutes, the continuous working temperature fluctuation of the print head was <±3℃, and there was no paper jam or data error.
