Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an intelligent flushing catheter device. Background Technology

[0002] In modern medical care, especially in postoperative care and abdominal cavity irrigation, catheter devices are widely used to deliver medical fluids such as saline solution to flush wounds and remove impurities from the body. However, traditional irrigation catheters have many problems in practical use and are difficult to meet current medical needs.

[0003] First, traditional catheter devices lack temperature control. In low-temperature environments, the temperature of saline solution is often low, and direct use may cause discomfort to patients due to excessively low fluid temperature, even adversely affecting the recovery process. Therefore, maintaining fluid temperature in cold seasons or under special medical conditions becomes a pressing issue. Second, catheters are easily bent or pulled during use due to blankets or patient movement. This can not only affect fluid flow and reduce flushing effectiveness but may also damage or dislodge the catheter due to excessive force. Traditional catheter devices have relatively simple designs for anti-pull and fixation, lacking effective cushioning and support functions. Furthermore, traditional catheter devices are usually mechanically designed, lacking intelligent monitoring and feedback functions. Healthcare personnel cannot monitor the catheter's status in real time, such as whether fluid flow is smooth or whether the catheter is within the normal stress range. If abnormalities occur, healthcare personnel often fail to detect them promptly, potentially posing risks to the patient.

[0004] To address the above issues, the development of an intelligent flushing catheter device is particularly necessary. This device should possess constant temperature heating, external force buffering protection, and intelligent monitoring functions. It can not only significantly improve patient comfort and safety but also enhance the work efficiency of medical staff, providing a more efficient and reliable solution for medical care. Utility Model Content

[0005] The purpose of this invention is to provide an intelligent flushing catheter device. By combining constant temperature heating technology, an external force buffer protection device, and an intelligent monitoring system, it achieves precise temperature control of physiological saline during flushing, ensures catheter safety, and provides real-time status monitoring. This solves the problems of unsuitable liquid temperature, susceptibility to external force damage, and lack of intelligent feedback in existing technologies. This invention is designed for postoperative flushing and abdominal catheter care in medical nursing scenarios, improving the patient experience and convenience of medical and nursing work.

[0006] To achieve the above objectives, this utility model provides an intelligent flushing catheter device, including a catheter body, a heating device, and an anti-pull device; one end of the catheter body is connected to a saline delivery tube, and the other end is connected to an outlet tube for discharge; the heating device is sleeved in the middle of the catheter body for heating the flowing saline at a constant temperature; the anti-pull device is located on the outside of the catheter body for buffering external pulling forces and protecting the catheter from bending or damage.

[0007] The heating device includes a housing, a heating element, and a temperature control module. The heating element is installed on the inner wall of the housing and is powered by a power module. The temperature control module monitors and adjusts the working status of the heating element in real time to maintain the saline solution flowing through the catheter within a suitable temperature range for the human body. Simultaneously, the heating device is designed with an external heat insulation layer to reduce heat loss and improve heating efficiency.

[0008] The anti-pull device includes a slide groove, a slider, a spring, an auxiliary block, and a locking rod. The slide groove is set on the inner wall of the auxiliary block, and the slider can slide in the slide groove. The spring is wrapped around the surface of the locking rod to buffer and reset the pulling force generated by the slider. The two ends of the auxiliary block are connected to the locking rod through hinge shafts to realize the overall anti-pull function and avoid the conduit from bending, breaking, or loosening due to external force.

[0009] The anti-pull device of this utility model integrates a sensor group and an intelligent feedback system. The sensor group includes a tension sensor and a displacement sensor to monitor the tension state of the catheter and the displacement of the slider in real time. The intelligent feedback system analyzes the data collected by the sensor group, triggers an alarm signal when an abnormal situation occurs, and can send the data to a remote medical monitoring terminal through a wireless communication module to remind medical staff to intervene in a timely manner.

[0010] This invention incorporates a support device on the surface of the catheter body, which is fixed to the edge of the bed via an adjustable bracket. This prevents bedding from compressing the catheter body and keeps the catheter unobstructed, preventing bending or blockage. The design of this device further enhances safety, ease of operation, and applicability, providing an efficient, intelligent, and reliable flushing catheter solution for medical and nursing scenarios.

[0011] The beneficial effects of this invention: Traditional catheters lack temperature control, and the direct delivery of saline solution in a low-temperature environment can easily cause discomfort to patients due to the excessively low fluid temperature, especially in cold seasons or postoperative care. To address this, this invention features a temperature-controlled heating device. Utilizing an intelligent temperature control module and a high-efficiency heating element, it can monitor and adjust the saline solution temperature in real time, ensuring the fluid remains within a suitable temperature range for the human body (e.g., 35°C to 38°C). This design effectively solves the adverse effects of low-temperature fluids on patients, significantly improving patient comfort during the flushing process.

[0012] Furthermore, traditional catheters are susceptible to bending and pulling due to bedding or patient movement during use, which can lead to catheter breakage, loosening, or obstructed infusion, reducing the safety and reliability of the device. This invention addresses this issue with an innovative anti-pull device that incorporates a sliding groove, slider, and spring to buffer and disperse external forces. When the catheter is subjected to external force, the slider moves within the groove, and the spring absorbs the impact, preventing the force from being directly transmitted to the catheter body. This ensures the catheter remains intact and unobstructed, further enhancing the device's resistance to external forces and extending its lifespan.

[0013] Finally, traditional catheter devices lack intelligent functions, making it impossible for medical staff to monitor the stress state or fluid flow of the catheter in real time, and abnormal situations are often difficult to detect and handle in a timely manner. This invention integrates a sensor array and an intelligent feedback system into the anti-pull device, enabling real-time monitoring of the catheter's stress state and slider displacement. When the tension exceeds a preset threshold or the slider displacement exceeds the limit, the intelligent feedback system automatically triggers an alarm and transmits the abnormal data to a remote medical monitoring terminal via a wireless communication module, ensuring timely intervention by medical staff and significantly improving the device's intelligence level and safety.

[0014] Furthermore, the heating device can employ zoned temperature control technology, setting multiple heating modules in different flow sections of the catheter. The temperature control system precisely adjusts the temperature of each section, ensuring the saline solution remains within a constant temperature range while minimizing energy waste. In addition, the heating modules can utilize low-power ceramic heating elements, combined with a heat recovery device to recycle externally lost heat, thereby improving the device's energy efficiency ratio and meeting the low-power requirements of long-term nursing scenarios.

[0015] Furthermore, the spring in the anti-pull device can be made of alloy materials with high elasticity and fatigue resistance, such as shape memory alloys, to further improve the spring's buffering capacity and service life. Simultaneously, a low-friction coating, such as a Teflon coating, can be added between the groove and the slider to reduce sliding resistance and ensure smooth slider movement. To adapt to the catheter force requirements in different medical environments, the anti-pull device can also be designed with an adjustable elastic mode, allowing for precise buffering and flexible response to external forces by replacing the spring or adjusting the connection angle of the locking rod.

[0016] Furthermore, the sensor array can employ a real-time monitoring system based on multi-sensor fusion, including pressure sensors, tension sensors, and displacement sensors, to achieve comprehensive monitoring of the conduit's operational status. The sensor array can utilize high-precision signal processing algorithms, such as wavelet transform denoising technology, to improve the reliability and accuracy of the monitoring data. The intelligent feedback system can further incorporate machine learning algorithms, such as anomaly pattern recognition models based on historical data, to predict potential abnormal tension or impaired fluid flow in real time and proactively issue early warning signals before such events occur, thereby enhancing the system's proactive protection capabilities.

[0017] Furthermore, the intelligent feedback system can be integrated with the hospital's Internet of Things (IoT) platform, enabling real-time connection with the patient monitoring system via a wireless communication module. Abnormal information can be simultaneously transmitted to the nurses' station or mobile terminals, ensuring timely response from medical staff. In addition, intelligent control terminals can be developed, allowing medical staff to remotely adjust heating temperatures, anti-pull device operating modes, or alarm thresholds via mobile devices, further enhancing the equipment's adaptability and intelligence.

[0018] Furthermore, to meet the needs of special medical scenarios, the materials used for the catheter body and support device can be high-molecular composite materials with antibacterial properties, such as silver ion-doped polymers, to reduce the risk of infection. The catheter support device is structurally optimized for a foldable design, facilitating flexible adjustment and use during patient movement. An adsorption device, such as a vacuum suction cup or magnetic structure, can be designed at the bottom of the support device to enhance stability and prevent catheter displacement due to patient movement.

[0027] See Figure 1 This is a schematic diagram of the overall structure of the intelligent flushing catheter device. In this embodiment, the device includes a catheter body 1, a heating device 2, and an anti-pull device 3. The catheter body 1 is the main flow channel, with one end connected to a saline delivery tube and the other end connected to an outlet tube for discharge, used to realize the function of saline delivery and discharge. The heating device 2 is sleeved in the middle of the catheter body 1 to heat the flowing saline. The anti-pull device 3 is set on the outside of the catheter body 1 to protect the catheter from bending or damage when subjected to external force, and at the same time to support and fix the catheter.

[0028] See Figure 2 The heating device 2 includes a housing and a heating element mounted on the inner wall of the housing. The heating element is powered by a power module. The intelligent temperature control module of the heating device can monitor and adjust the heating temperature in real time to ensure that the flowing saline solution maintains a constant temperature within a suitable range for the human body, thereby preventing discomfort to the patient due to the low-temperature flushing solution. The intelligent temperature control module has a built-in temperature sensor to detect the real-time temperature of the saline solution and activates or deactivates the heating element based on temperature deviations.

[0029] See Figure 3 This is an enlarged schematic diagram of the specific components of the anti-pull device 3. The anti-pull device 3 includes a slide groove 31, a slider 32, a spring 33, an auxiliary block 34, and a locking rod 35. The slide groove 31 is located on the inner wall of the auxiliary block 34, allowing the slider 32 to slide within it. The locking rod 35 passes through the slider 32, and the spring 33 is wrapped around the surface of the locking rod 35 and fixed to both ends of the auxiliary block 34 to buffer the impact force during external pulling. Under the action of external force, the slider 32 slides into the slide groove 31, where the spring 33 buffers it and elastically resets it after the external force is removed, ensuring that the conduit body 1 remains stable and unobstructed.

[0030] Furthermore, the anti-pull device 3 integrates an external sensor group for real-time monitoring of the device's status. The sensor group includes a tension sensor and a displacement sensor. The tension sensor monitors the magnitude of the external force, while the displacement sensor monitors the displacement of the slider 32 within the groove 31. The sensor data is processed by an intelligent feedback system. When the external force exceeds a preset threshold, the intelligent feedback system triggers an alarm signal and transmits the data to a remote medical monitoring terminal via a wireless communication module, alerting medical personnel to intervene promptly.

[0031] To ensure catheter stability, please refer to... Figure 2 The surface of the catheter body 1 is provided with a support device. The support device is fixed to the edge of the bed by an adjustable bracket to prevent the bedding from compressing the catheter body 1, while keeping the catheter unobstructed and preventing bending or blockage.

[0032] In summary, this embodiment, by integrating the heating device 2 and the anti-pull device 3, not only ensures the constant temperature of the saline solution but also provides reliable support and protection for the catheter body 1, effectively avoiding problems caused by stress or temperature changes on the catheter during flushing, and improving the safety and convenience of use.
