Description

Technical Field

[0001] This invention relates to the field of medical equipment technology, specifically to an infusion flow regulator and an infusion device. Background Technology

[0002] In modern healthcare, intravenous infusion is a common and crucial treatment method, widely used in the treatment of various diseases. Precise control of the infusion rate is essential for ensuring accurate drug dosage, improving treatment efficacy, and protecting patient safety. Inappropriate infusion rates can lead to a series of adverse consequences. For example, an excessively rapid infusion rate increases the burden on the patient's heart and blood vessels, and in patients with weak cardiopulmonary function, may even induce serious complications such as acute heart failure and pulmonary edema. Conversely, an excessively slow infusion rate may prevent the medication from taking effect in time, delaying treatment and hindering the patient's recovery process.

[0003] Currently, existing infusion rate control devices on the market have many shortcomings. Drip controllers typically consist of a graduated transparent container and a manually adjustable valve. Healthcare professionals control the drip rate by observing the dripping flow within the container and manually adjusting the valve's opening. From a structural design perspective, this simple construction results in relatively low cost and an uncomplicated manufacturing process, making it still valuable in cost-sensitive medical settings such as primary care clinics and remote medical institutions. However, drip controllers heavily rely on manual monitoring. Healthcare professionals need to frequently observe the drip rate and manually adjust the valve based on their observations. Some healthcare professionals may have visual errors when observing the drip rate, or they may apply different amounts of force when adjusting the valve; these factors can all lead to errors in drip rate control.

Detailed Implementation

[0032] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Please see the appendix Figure 1 - Appendix Figure 5 This invention provides an infusion flow regulator and infusion device, including a housing 1, a battery 12 disposed on the upper surface of the housing 1, an outer shell 2 disposed on the upper surface of the housing 1, the battery 12 disposed inside the outer shell 2, a motor 24 disposed inside the outer shell 2, the outer wall of the motor 24 disposed on the upper surface of the housing 1, a bevel gear 23 disposed at the output end of the motor 24, a bevel gear 21 meshing with the tooth end of the bevel gear 23, a rotating shaft 22 fixedly disposed in the middle of the bevel gear 21, a gear 20 fixedly disposed at the top end of the rotating shaft 22, and the bottom end of the rotating shaft 22 rotatably connected to the upper surface of the housing 1, a gear ring 15 meshing with the tooth end of the gear 20, a knob 3 disposed on the inner wall of the gear ring 15, the outer wall of the knob 3 rotatably connected to the upper surface of the outer shell 2, a handle 4 fixedly disposed on the upper surface of the knob 3, a rotating shaft 16 fixedly disposed on the lower surface of the knob 3, and an adjustment component disposed at the bottom end of the rotating shaft 16.

[0034] Specifically, there are two adjustment methods when the infusion flow rate needs to be adjusted. In manual adjustment, medical staff operate the handle 4 to rotate the knob 3. The knob 3 is connected to the gear ring 15; rotating the knob 3 causes the gear ring 15 to rotate accordingly. The gear ring 15 meshes with the gear 20, and the rotation of the gear ring 15 drives the gear 20 to rotate. The gear 20 is fixed on the rotating shaft 22, causing the rotating shaft 22 to rotate. The bevel gear 21 on the rotating shaft 22 also rotates, meshing with the bevel gear 23, which in turn drives the bevel gear 23 to rotate, ultimately driving the motor 24 connected to the bevel gear 23. After the motor 24 rotates, through a series of transmissions, the rotating shaft 16, which is fixedly connected to the lower surface of the knob 3, rotates. One of the power sources for this device is the battery 12, which supplies power to the entire device, ensuring the normal operation of all components. When more precise adjustments are needed, the control and communication module 27 can control the motor 24 to operate actively based on the data transmitted from the monitoring and display module 26. This motor, via the same gear transmission system, drives the rotating shaft 16 to rotate. The rotation of the rotating shaft 16 adjusts the infusion channel within the connecting tube 6, changing the infusion flow rate.

[0035] By combining manual and automatic adjustment methods, precise regulation of the infusion flow rate can be achieved. Medical staff can first make a preliminary adjustment by manually operating the handle 4, and then use the control and communication module 27, combined with monitoring data, to drive the motor 24 for precise fine-tuning. This allows the infusion rate to be flexibly adjusted according to the patient's condition, drug characteristics, and other factors to meet different infusion requirements. Simultaneously, the device has a compact and reasonable structural design, with all components working together to ensure stable and reliable operation. Whether in routine hospital infusion scenarios or in special situations such as patient transport, it ensures a smooth infusion process and reduces infusion interruptions caused by device malfunctions. This solves the problem of poor precision control of the infusion rate.

[0036] Please see the appendix Figure 2 - Appendix Figure 5 The adjustment assembly includes an adjustment block 11. The top of the adjustment block 11 is fixedly mounted on the outer wall of the rotating shaft 16. A sealing ring 10 is provided on the outer wall of the adjustment block 11. A connecting pipe 6 is provided on the outer wall of the sealing ring 10. The outer wall of the connecting pipe 6 is located inside the housing 1. A retaining ring 7 is provided at both ends of the connecting pipe 6. A connecting band 9 is provided on the outer wall of the retaining ring 7. A rubber cap 8 is provided at one end of the connecting band 9. The inner wall of the rubber cap 8 is located on the outer wall of the connecting pipe 6. A flow rate sensor 13 is provided on the outer wall of the connecting pipe 6. A ratchet mechanism is fixedly mounted on the rotating shaft 16 through the housing 1 and the connecting pipe 6.

[0037] Specifically, when the rotating shaft 16 rotates under the drive of the motor 24 or the manual operation knob 3 and handle 4, the adjusting block 11, which is fixedly connected to it, rotates accordingly. The special structural design of the adjusting block 11 allows it to change the size of the infusion channel inside the connecting tube 6 during rotation. The sealing ring 10 fits tightly between the adjusting block 11 and the connecting tube 6, providing a seal and preventing liquid leakage from the gap between the adjusting block 11 and the connecting tube 6, thus ensuring the integrity and safety of the infusion. The retaining rings 7 at both ends of the connecting tube 6 are used to fix the connecting strap 9, which is connected to the rubber cap 8 to prevent the rubber cap 8 from shaking or falling off. The rubber cap 8 is fitted over the outer wall of the connecting tube 6. When the infusion device is not in use, the rubber cap 8 can prevent external dust, impurities, etc., from entering the connecting tube 6 and contaminating the infusion liquid. The flow rate sensor 13 monitors the flow rate of the liquid in the connecting tube 6 in real time. It converts the flow rate information into an electrical signal by sensing the physical signal generated when the liquid flows, and transmits it to the monitoring and display module 26 and the control and communication module 27.

[0038] By adjusting the infusion channel of the connecting tube 6 using the regulating block 11, combined with the real-time feedback from the flow rate sensor 13, the infusion flow rate can be precisely controlled within the required range to meet the infusion requirements of different patients and medications. Good sealing and stability are also ensured; the sealing ring 10 prevents liquid leakage, and the rubber cap 8 protects the infusion fluid from contamination, making the entire infusion process safe and reliable and reducing medical risks caused by leakage and contamination. Real-time monitoring of the infusion flow rate, with the flow rate sensor 13 continuously operating, allows medical staff and the control and communication module 27 to monitor the infusion rate at any time, facilitating timely detection and adjustment of abnormalities, further improving the safety and accuracy of the infusion. This also solves the problem of poor product durability and safety.

[0039] Please see the appendix Figure 2 - Appendix Figure 4 Appendix Figure 6 The ratchet mechanism includes a ratchet 14, the upper surface of which is fixedly mounted on the bottom end of a rotating shaft 16. A rotating shaft 25 is rotatably connected to the middle of the ratchet 14. A fixing block 17 is fixedly mounted on one end of the rotating shaft 25. A rotating shaft 28 is fixedly mounted on one end of the fixing block 17. A pawl 19 is rotatably connected to the outer wall of the rotating shaft 28. The pawl 19 is connected to the tooth end of the ratchet 14. The lower surface of the fixing block 17 is fixedly mounted on the bottom end of the inner wall of the housing 1.

[0040] Specifically, the ratchet mechanism plays a unidirectional limiting role in the entire infusion flow regulator and infusion device. The ratchet 14 is fixed to the bottom end of the rotating shaft 16. When the rotating shaft 16 rotates in the same direction as the normal infusion flow regulation, it drives the ratchet 14 to rotate as well. The pawl 19, connected to the teeth of the ratchet 14, slides on the tooth surface of the ratchet 14. Since the pawl 19 is rotatably connected to the fixed block 17 via the rotating shaft 18, and the fixed block 17 is fixed to the bottom of the inner wall of the housing 1, its position is relatively stable. Therefore, the pawl 19 will pass over each tooth sequentially as the ratchet 14 rotates, without obstructing the forward rotation of the ratchet 14, thus enabling the entire regulating mechanism to smoothly perform infusion flow regulation. However, when the rotating shaft 16 tends to rotate in the opposite direction due to unexpected external forces or other factors, the teeth of the ratchet 14 will interact with the pawl 19. Under its own weight and the position and angle defined by the fixed block 17 and the second pivot 18, the pawl 19 will lock the teeth of the ratchet 14, preventing the ratchet 14 from rotating in the opposite direction. Furthermore, the middle of the ratchet 14 is rotatably connected to the fixed block 17 via the fourth pivot 25, allowing the ratchet 14 to rotate flexibly around the fourth pivot 25 when rotating in the forward direction. Simultaneously, when reverse rotation is obstructed, it can stably maintain its current position due to its connection with the fourth pivot 25, preventing loosening or displacement caused by external impact.

[0041] This ratchet mechanism effectively limits reverse rotation during infusion flow rate adjustment, ensuring the stability and accuracy of the adjustment. Once medical staff adjusts the infusion flow rate to an appropriate value based on the patient's condition and other factors, even external interference such as tubing vibration or accidental contact with the device will not alter the adjusted flow rate due to reverse rotation of the rotating shaft 16, ensuring the infusion rate remains within the preset safe and effective range. This further guarantees the smooth operation of the entire infusion process, improves the reliability of the infusion procedure, and eliminates the need for medical staff to frequently worry about abnormal changes in infusion flow rate caused by external factors, allowing them to focus more on observing the patient's overall condition and other nursing care. This improves work efficiency and alleviates the problem of heavy workload for medical staff.

[0042] Please see the appendix Figure 7 - Appendix Figure 10 The housing 1 includes a monitoring and display module 26, a control and communication module 27, and a power supply module 28. The monitoring and display module 26 is used to monitor the infusion status in real time and provide feedback on the infusion information. The control and communication module 27 is used for control and information interaction in the infusion flow regulator and infusion device. The power supply module 28 is used to provide power support to ensure the normal operation of the entire device. The housing 1 is used to receive electrical signals sent by the monitoring and display module 26, the control and communication module 27, and the power supply module 28, and to monitor and provide feedback on the working status.

[0043] The monitoring and display module 26 includes a flow rate sensor 13 and a display 5. The flow rate sensor 13 is used to monitor the infusion flow rate in real time and provide a data basis for the precise control of the infusion flow rate. The display 5 is used for information display, showing the current infusion rate and displaying the total amount of fluid that has been injected into the patient's body in real time.

[0044] Specifically, the flow rate sensor 13 typically uses specific physical principles to detect the flow of liquid within the connecting tube 6. Based on the principle of electromagnetic induction, when liquid flows past the sensor's location, it alters the internal magnetic field environment, thereby generating a corresponding electrical signal. There is a specific correspondence between the electrical signal and the liquid flow rate. The flow rate sensor 13 continuously transmits the real-time monitored electrical signal, representing the liquid flow rate, to the microprocessor 29 in the control and communication module 27. The display 5 is connected to the control and communication module 27 and receives the processed data from the microprocessor 29. The microprocessor 29 analyzes and converts the electrical signal acquired from the flow rate sensor 13 into intuitive flow rate values ​​and the cumulative infusion volume. Then, the display 5, through its internal display driver circuit, visually displays these values, allowing medical staff and patients to clearly see the current infusion rate and the total amount of fluid already infused into the patient's body.

[0045] Through real-time, precise monitoring by the flow rate sensor 13 and its coordinated operation with the control and communication module 27, reliable data support is provided for the precise control of infusion flow rate. Medical staff can use accurate flow rate data to promptly determine whether the infusion rate meets the requirements of the patient's condition and drug characteristics, and thus make corresponding adjustments to ensure that the infusion flow rate is always maintained within the ideal and precise range, greatly improving the accuracy of infusion therapy. This solves the problem of difficult infusion rate control.

[0046] The control and communication module 27 includes a microprocessor 29, a wireless communication module 30, and an alarm module 31. The microprocessor 29 is used for data processing, logical judgment, and command transmission to ensure accurate control and stable operation of the entire infusion process. The wireless communication module 30 is used to establish a wireless connection between the device and the outside world to realize data transmission and interaction. The alarm module 31 is used to issue alarm signals to indicate abnormal situations during the infusion process.

[0047] Specifically, the microprocessor 29 receives electrical signals representing the infusion flow rate from the flow sensor 13. These electrical signals carry real-time flow rate data. The microprocessor 29 processes this data using a built-in algorithm, converting it into a recognizable and comparable numerical form. Then, the microprocessor 29 performs a logical comparison between the actual flow rate value and the preset infusion rate parameters. When the actual flow rate is inconsistent with the preset parameters, the microprocessor 29 generates corresponding instructions based on the deviation and sends these instructions to relevant regulating components such as the motor 24. The wireless communication module 30 incorporates wireless communication protocol standards such as Bluetooth and Wi-Fi, enabling it to pair and connect with external devices. In a hospital environment, it can establish wireless links with the hospital information system and the mobile terminals of medical staff. It packages the relevant infusion data processed by the microprocessor 29, such as real-time infusion flow rate, total infusion volume, remaining infusion time, and equipment operating status, according to a predetermined communication protocol format and then transmits it wirelessly. Simultaneously, it can also receive instructions and updated parameters from external devices. The alarm module 31 is connected to the microprocessor 29. During the real-time monitoring and logical judgment of the infusion data, if the microprocessor 29 detects that the infusion flow rate exceeds the preset safety range, or when it detects that the infusion is about to end, or when a critical component of the device malfunctions, the microprocessor 29 will send a trigger signal to the alarm module 31.

[0048] The wireless connection established by the wireless communication module 30 allows medical staff to overcome spatial limitations and remotely monitor the infusion status of multiple patients in real time through the hospital information system or mobile terminals, without having to be by the patient's bedside at all times. This enables them to obtain comprehensive infusion data promptly and facilitate overall management, thus solving the problem of spatial limitations in infusion monitoring.

[0049] The power module 28 includes a battery 12, which provides power support for the stable operation of the entire device and ensures the smooth progress of the infusion process.

[0050] Specifically, while the power module 28 supplies power to the infusion flow regulator and infusion device, the battery 12 undergoes a reverse chemical reaction process. The chemical energy stored within it reacts at the electrodes, causing electrons to move directionally in the circuit, forming an electric current that powers the various electrical components within the device. These components include the motor 24, enabling it to operate normally and drive the relevant mechanical structures for regulating the infusion flow; providing a stable operating voltage to the flow rate sensor 13, ensuring it can accurately monitor the infusion flow rate and continuously output an electrical signal representing the flow rate; powering the microprocessor 29, allowing it to smoothly complete key operations such as data processing, logical judgment, and command transmission; and also providing power to other components such as the display 5, wireless communication module 30, and alarm module 31, ensuring they each perform their respective functions and maintain the normal operation of the entire device.

[0051] Working principle: When using this device, medical staff can first manually operate the handle to rotate the knob. The knob rotates the gear ring, which, through a gear transmission system consisting of gears, bevel gear one, and bevel gear two, causes the rotating shaft connected to the knob to rotate. Simultaneously, it drives the motor, achieving initial adjustment of the infusion flow rate. Furthermore, the microprocessor in the control and communication module can precisely control the motor's operation according to actual needs, further precisely adjusting the flow rate.

[0052] The connecting tube penetrates the shell, and a flow rate sensor on its outer wall monitors the infusion flow rate in real time. It converts the flow rate information into an electrical signal using principles such as electromagnetic induction or pressure difference, and transmits this signal to the microprocessor. The microprocessor compares and analyzes the received signal with preset parameters. If the flow rate does not meet the requirements, it sends a command to the motor to adjust the position of the regulating block, changing the size of the infusion channel within the connecting tube, thus precisely controlling the infusion rate.

[0053] The battery in the power module supplies power to the entire device, ensuring the stable operation of each component. It stores and releases electrical energy through chemical reactions, maintaining the continuous operation of the device in different scenarios.

[0054] In a ratchet mechanism, the ratchet rotates with the shaft. When rotating normally in the forward direction, the pawl slides on the ratchet teeth without obstruction. If there is a tendency to rotate in the reverse direction, the pawl will lock the ratchet teeth to prevent the flow regulation from changing in the opposite direction due to external forces, thus ensuring a stable infusion rate.

[0055] The wireless communication module establishes a wireless connection with external devices, enabling data transmission and facilitating remote monitoring and management. The alarm module receives signals from the microprocessor and issues an alarm to alert medical staff when there is abnormal flow rate, the infusion is about to end, or equipment malfunction. The display shows information such as infusion flow rate and total infusion volume, allowing medical staff and patients to easily monitor the infusion status. All components of the entire device work together to ensure a precise, safe, and smooth infusion process.

[0056] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
