Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, and in particular to a monitoring watch for ICU nurses. Background Art

[0002] In the ICU ward, patients' conditions are extremely critical and require extremely high real-time monitoring. ICU nurses bear enormous work pressure, and their work content is complicated and busy. They not only need to pay attention to patients' vital signs at all times, but also need to frequently perform intravenous infusions and other operations. There are currently many problems. For example, when nurses take patients out for CT scans and other examinations, they have to hand over other patients to other nurses for care, which undoubtedly increases the safety risks of patient monitoring.

[0003] In terms of intravenous infusion, ICU patients are seriously ill and often require multiple drugs to be administered intravenously. Most patients also have cardiopulmonary insufficiency. Manual adjustment of the infusion drip rate is not only inaccurate, but also difficult to fully consider the patient's cardiopulmonary acceptance due to the heavy workload of nurses. In addition, there is a lack of an effective alarm mechanism at the end of liquid infusion, and it is completely dependent on nurse patrols. This not only greatly increases the workload of nurses, but may also have an adverse effect on the patient's treatment effect and health status due to problems such as interruption of multiple bags of drug infusion, poor drip rate control, and blockage of intravenous infusion lines.

[0004] Therefore, those skilled in the art provide a monitoring watch for ICU nurses to solve the problems raised in the above background technology. Summary of the Invention

Many modifications and variations will be apparent to those skilled in the art. The embodiments are chosen and described to better illustrate the principles of the invention and its practical application, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for specific applications.

[0042] Example 1

[0043] See also Figures 1 to 8In this embodiment, a monitoring watch for ICU nurses is provided, which includes a patient monitor, an electronic medical record system, and a watch body 1, as well as a control module 4, a communication module 5, a storage module 6, an alarm module 7, a power module 8, a display module 9 and an operation button arranged in the watch body 1. The control module 4 is electrically connected to the communication module 5, the display module 9, the storage module 6, the alarm module 7, the power module 8 and the control button respectively. The upper end of the watch body 1 is fixedly connected to a protective shell 2, and a limit ring 3 is fixedly connected to the inner wall of the protective shell 2. The display module 9 is fixedly connected to the upper end of the limit ring 3 by bolts, and the upper end of the protective shell 2 is detachably connected to a protective component 10.

[0044] The communication module 5 is used to establish a wireless connection with the patient monitor and receive real-time patient vital signs data monitored by the patient monitor, such as heart rate, blood pressure, blood oxygen saturation, respiratory rate, etc. The communication module 5 uses wireless communication technologies such as Bluetooth and Wi-Fi to ensure stable and fast data transmission.

[0045] The display module 9 is the display screen of the monitoring watch, which is used to display the patient's vital signs data, infusion drip rate, infusion volume, remaining infusion time and other information; the display module 9 uses a high-resolution, high-contrast display screen to ensure that nurses can clearly read the information under different ambient light conditions; at the same time, the display screen is electrically connected to the operation button, and the nurse can use the operation button to switch display pages, view detailed information, etc.

[0046] The storage module 6 is used to store the patient's historical vital signs data, infusion records, watch operation logs and other information; the storage module 6 uses a large-capacity storage chip to meet the needs of long-term data storage; the stored data can be uploaded to the hospital information system through the communication module 5, and can also be used by medical staff for query and analysis on the watch when necessary.

[0047] The alarm module 7 includes a sound alarm unit and a vibration alarm unit. When the patient's vital signs are abnormal, such as a heart rate that is too fast or too slow, blood pressure that is too high or too low, etc., or when the infusion is abnormal, such as an abnormal drip rate, a blockage in the infusion tube, or the liquid is about to be delivered, the control module 4 triggers the alarm module 7, the sound alarm unit emits a loud alarm sound, and the vibration alarm unit generates strong vibrations to remind the nurse to deal with it in time.

[0048] The power module 8 provides power for the smart monitoring watch and uses a rechargeable lithium battery. The watch body 1 is equipped with a charging port, allowing nurses to charge the battery at any time. At the same time, the power module 8 has a power management function that can optimize battery usage efficiency and extend the watch's battery life.

[0049] It also includes an infrared sensor assembly for monitoring the infusion drip rate and a flow sensor for monitoring the infusion volume. The infrared sensor assembly and the flow sensor are both electrically connected to the control module 4. The infrared sensor assembly is clamped on the infusion tube and detects the flow of liquid in the infusion tube by emitting and receiving infrared rays to calculate the infusion drip rate. The flow sensor is set on the infusion tube to monitor the cumulative amount of infusion. The control module 4 is preset with data such as reasonable infusion drip rate ranges and infusion volume thresholds for different drugs and patient conditions. When the data received from the infrared sensor and the flow sensor exceeds the preset range, it is judged as an infusion abnormality and the alarm module 7 is triggered.

[0050] Communication module 5 can also establish a connection with the hospital's electronic medical record system. Nurses enter information such as the patient's Braden score, body position, or skin problems on the monitoring watch. Control module 4 transmits this information to the electronic medical record system via communication module 5. The electronic medical record system analyzes the rationality of the dressing selection based on pre-set algorithms and rules, and feeds the results back to the watch's display module 9 via communication module 5 for the nurse's reference.

[0051] Among them, the protective component 10 includes a protective fixing groove 11 opened inside the protective shell 2, a protective glass plate 12 arranged at the upper end of the protective shell 2, three groups of mounting grooves 13 opened at the upper end of the protective shell 2, and three groups of mounting arc plates 14 fixedly connected to the lower end of the protective glass plate 12. The lower end of the mounting arc plate 14 passes through the mounting groove 13 and is connected to the inside of the protective fixing groove 11. The inside of the protective fixing groove 11 is connected with a protective limiting mechanism for limiting the mounting arc plate 14. The outer side of the protective shell 2 is connected to a protective driving mechanism for driving the protective limiting mechanism.

[0052] The protective drive mechanism includes a rotating ring 17 rotatably connected to the outside of the protective shell 2. A trapezoidal limiting ring groove 15 is provided on the outside of the protective shell 2. A trapezoidal limiting arc member 16 is slidably connected to the inside of the trapezoidal limiting ring groove 15. The trapezoidal limiting arc member 16 is welded to the outside of the rotating ring 17. In addition, multiple sets of limiting telescopic mechanisms for limiting the rotating ring 17 are connected to the outside of the protective shell 2.

[0053] The limiting telescopic mechanism includes a receiving cylindrical groove 26 opened on the outside of the protective shell 2, a receiving arc groove 27 opened inside the rotating ring 17, and a limiting member 28 slidably connected to the inside of the receiving cylindrical groove 26. A spring 29 is fixedly connected between one end of the limiting member 28 and the inner wall of the receiving cylindrical groove 26, and the other end of the limiting member 28 is slidably connected to the inside of the receiving arc groove 27.

[0054] The protective limiting mechanism includes three groups of rotating through grooves 18 opened on the outside of the protective shell 2, three groups of rotating connecting plates 19 fixedly connected to the inner side of the rotating ring 17, and a driving ring plate 20 fixedly connected to one end of the three groups of rotating connecting plates 19. The rotating connecting plate 19 is slidably connected to the inside of the rotating through groove 18, and the driving ring plate 20 is rotatably connected to the inside of the protective fixed groove 11; it also includes three groups of arc grooves 21 opened at the upper end of the driving ring plate 20, a cylindrical driving member 22 slidably connected to the inside of the arc groove 21, and a limiting arc plate 23 fixedly connected to the upper end of the cylindrical driving member 22, and three groups of limiting plates are fixedly connected to the inside of the protective fixed groove 11, and the upper ends of the three groups of limiting plates are all provided with movable limiting grooves 24. The lower ends of the three groups of cylindrical driving members 22 are all fixedly connected with movable limiting blocks 25, and the movable limiting blocks 25 are slidably connected to the inside of the movable limiting groove 24.

[0055] A hanging slot 30 is provided inside the watch body 1, and a wristband 31 is slidably connected to the inside of the hanging slot 30. A Velcro surface 32 is fixed to the upper end of one side of the wristband 31 by sewing, and a Velcro hook surface 33 is fixed to the lower end of the other side of the wristband 31 by sewing. The Velcro surface 32 and the Velcro hook surface 33 are arranged in coordination to facilitate fixing the watch body 1 on the nurse's wrist.

[0056] The lower end of the watch body 1 is fixedly connected to a circular silicone pad 34 by glue, which improves the stability of the fixed position of the watch body 1 and the nurse's wrist.

[0057] Before use, the nurse pairs the smart monitoring watch with the patient monitor through the communication module 5 to ensure that the patient's vital signs data can be received in real time. At the same time, the infrared sensor component and flow sensor for infusion monitoring are correctly installed on the infusion tube, and the patient's basic information, relevant parameters of the infused drugs, and the corresponding reasonable infusion drip rate range and infusion volume threshold are set in the display module 9 of the watch.

[0058] The communication module 5 continuously receives the vital signs data sent by the patient monitor and transmits it to the control module 4; after the control module 4 processes the data, it displays it to the nurse through the display module 9; if the vital signs data exceeds the preset normal range, the control module 4 immediately triggers the alarm module 7 to remind the nurse to pay attention to the patient's condition.

[0059] The infrared sensor monitors the infusion drip rate in real time, and the flow sensor monitors the infusion volume. Both transmit data to the control module 4; the control module 4 continuously compares the received data with the preset reasonable range; when the drip rate is too fast or too slow, or the infusion volume reaches the warning value, or the infusion tube is blocked, etc., the control module 4 triggers the alarm module 7 to notify the nurse by sound and vibration to adjust the infusion situation in time.

[0060] During the nursing process, if the nurse needs to evaluate the patient's Braden score, body position or skin problems and other conditions related to the selection of dressings, he or she can input relevant information through the control buttons on the smart monitoring watch; the control module 4 sends this information to the electronic medical record system through the communication module 5; after analysis and processing, the electronic medical record system feeds back the analysis results of the rationality of the dressing selection to the watch through the communication module 5, which is displayed on the display module 9, providing a decision-making basis for the nurse when selecting dressings.

[0061] The storage module 6 stores the patient's vital signs data, infusion records, and watch operation logs in real time; nurses can query historical data through the operation interface of the display module 9 when needed; at the same time, the stored data is regularly uploaded to the hospital information system through the communication module 5 for long-term data storage and further analysis and research;

[0062] The watch body 1 is fixed on the nurse's wrist through the hanging slot 30, the wristband 31, the Velcro surface 32, and the Velcro hook surface 33 for use;

[0063] When it is necessary to maintain the components in this solution, the rotating ring 17 is rotated forward. The rotating ring 17 drives the driving ring plate 20 to rotate by rotating the connecting plate 19. Under the action of the movable limiting groove 24, the movable limiting block 25 and the arc groove 21, the cylindrical driving member 22 drives the limiting arc plate 23 to move away from the installation arc plate 14, releasing the limit on the installation arc plate 14. Then, the protective glass plate 12 is pulled and removed from the protective case 2, and the components inside the watch body 1 and the protective case 2 are maintained.

[0064] After the maintenance is completed, the protective case 2 is placed on the upper end of the watch body 1, and the installation arc plate 14 enters the interior of the protective fixing groove 11 through the installation groove 13. The rotating ring 17 is rotated in the opposite direction to move the limiting arc plate 23 to the side of the installation arc plate 14. The installation arc plate 14 is fixed by the limiting arc plate 23. Under the action of the spring 29 and the limiting member 28, the receiving arc groove 2721 is limited. The rotating ring 17 will only rotate when an external force rotates the rotating ring 17.

[0065] The specific implementation methods of this disclosure omit detailed descriptions of known functions and known components (such as patient monitors, electronic medical record systems, etc.). To ensure the compatibility of the equipment, the operating methods adopted are consistent with the parameters of commercially available equipment.
