Description

Technical Field

[0001] The present invention relates to the technical field of medical supplies, and in particular to intelligent medical compression stockings. Background Art

[0002] In the medical field, lower limb venous diseases such as varicose veins seriously impact patients' quality of life. Medical graduated compression stockings, as an important adjunctive treatment product, play a key role. By establishing peak support pressure at the ankle and gradually decreasing pressure upwards along the leg, creating a specific pressure gradient, they effectively promote venous return in the lower limbs, relieving or improving the pressure on the lower limb veins and venous valves. This significantly improves the clinical symptoms of venous insufficiency and alleviates leg discomfort caused by varicose veins, mild ankle swelling, leg fatigue, and pregnancy edema.

[0003] However, the medical compression stockings currently available on the market have many shortcomings. On the one hand, most medical compression stockings have a simple structure and a relatively fixed design, and cannot flexibly adjust the pressure values of various parts according to the different medical conditions of patients. Different patients have different degrees of severity and lesion sites in their lower limb venous diseases, and their pressure requirements are also different. The existing unified pressure design is difficult to meet personalized treatment needs, which may result in some patients not being able to obtain the best treatment effect. On the other hand, the existing medical compression stockings have a low degree of intelligence and a single function. They usually only have basic pressure support functions, lack real-time monitoring and feedback on patient usage, and cannot provide doctors and patients with relevant data support to adjust treatment plans in a timely manner.

[0004] Therefore, there is an urgent need for a new type of intelligent medical compression stockings to provide an effective solution to the defects of existing technologies. Summary of the Invention

[0005] The purpose of the present invention is to provide an intelligent medical compression stocking to solve the problems raised in the above background technology.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A smart medical compression stocking comprises an elastic stocking tube, a multimodal sensor array module, and a control host: the elastic stocking tube is constructed to cover at least one of the foot, calf, and thigh, with the toes exposed at the end; the multimodal sensor array module is integrated into the inner surface of the elastic stocking tube on the side that is close to the leg muscles. The multimodal sensor array module includes a plurality of micro pressure sensors, which are unevenly arranged according to the anatomical distribution path of the lower limb veins, and are mainly distributed in the course of the great saphenous vein and the belly of the gastrocnemius muscle; the control host is externally arranged on the back side of the elastic stocking tube, close to the sock opening, and is equipped with a microprocessor, a communication module, and a power supply module. The multimodal sensor array module transmits data signals to the microprocessor in a unidirectional manner, and the microprocessor transmits data in a bidirectional manner with the cloud, a mobile phone, or a PC through the communication module.

[0008] Furthermore, a plurality of micro pressure regulating devices are evenly distributed on the front side of the elastic stocking tube. The micro pressure regulating device includes a pair of connecting plates respectively connected to the left and right sides of the elastic stocking tube. The connecting plates on both sides are connected by a non-elastic rope. The non-elastic rope is wound around the main shaft of the micro self-locking motor, and the microprocessor transmits a control signal to the micro self-locking motor in a unidirectional manner.

[0009] Furthermore, the rear side of the elastic stocking tube is provided with an opening running through from bottom to top, the opening is closed by a zipper, and one side of the opening is connected to an anti-pinch gasket of the same length as the zipper, and the anti-pinch gasket is located on the inner side of the zipper.

[0010] Furthermore, the multimodal sensor array module further includes at least one pair of bioelectrical impedance sensors.

[0011] Furthermore, the multimodal sensor array module further includes at least one temperature sensor.

[0012] Furthermore, the multimodal sensor array module also includes at least one blood oxygen concentration sensor.

[0013] Furthermore, the control host is also provided with an alarm module, which includes at least one of a speaker, a strobe LED light and a micro vibration motor.

[0014] Furthermore, the power supply module is a micro lithium battery or a piezoelectric power generation device or a body temperature difference power generation device.

[0015] Furthermore, the micro self-locking motor main shaft is provided with a hand-tightening mechanism.

[0016] Furthermore, an electric heating plate is integrated on the inner side of the elastic stocking tube.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The present invention uses micro pressure sensors to monitor the pressure distribution of various parts of the lower limbs in real time, and uses micro self-locking motors to dynamically adjust the pressure gradient, thereby realizing personalized pressure therapy. The treatment plan can be adjusted at any time according to changes in the patient's condition. At the same time, the integrated bioimpedance and blood oxygen sensors of the present invention can comprehensively monitor the blood flow status and tissue edema of the lower limbs, providing doctors with multi-dimensional physiological data support, making remote diagnosis and treatment and personalized program formulation possible. In addition, when the system detects abnormal physiological parameters, the present invention can alarm through various methods such as sound, light, and vibration to ensure that patients can receive medical intervention in a timely manner and improve treatment safety.

[0019] 2. The innovative zipper and anti-pinch gasket design of this invention solves the drawbacks of donning and doffing medical compression stockings. The zipper structure allows patients to easily don and doff the stocking without the need to stretch the stocking, making it suitable for the elderly and patients with limited mobility.

[0020] 3. The gentle heating of the electric heating plate in this invention promotes vasodilation, enhances venous return, and relieves lower extremity coldness or venous congestion. The temperature sensor is linked to the heating system to prevent overheating and damage to the skin, ensuring treatment safety. Temperature change data can reflect treatment effectiveness. For example, the speed of temperature recovery after heating can be used to assess vascular function, providing a basis for doctors to adjust treatment plans. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Example 1: Please refer to Figures 1 to 8 , a smart medical compression stocking, comprising an elastic stocking tube 1, a multimodal sensor array module, and a control host 2: the elastic stocking tube 1 is constructed to cover at least one part of the foot, calf and thigh, with the toes exposed at the end; the multimodal sensor array module is integrated into the inner surface of the elastic stocking tube 1 on the side close to the leg muscle, the multimodal sensor array module includes a plurality of micro pressure sensors 10, and the micro pressure sensors 10 are unevenly arranged according to the anatomical distribution path of the lower limb veins, and are mainly distributed in the course area of the great saphenous vein and the belly area of the gastrocnemius muscle; the control host 2 is externally arranged on the back side of the elastic stocking tube 1 close to the sock opening, and the control host 2 is equipped with a microprocessor, a communication module and a power supply module. The multimodal sensor array module transmits data signals to the microprocessor in a unidirectional manner, and the microprocessor transmits data in a bidirectional manner with the cloud or mobile phone or PC through the communication module.

[0032] A plurality of micro pressure regulating devices 6 are evenly distributed on the front side of the elastic stocking tube 1. The micro pressure regulating device 6 includes a pair of connecting plates 8 respectively connected to the left and right sides of the elastic stocking tube 1. The connecting plates 8 on both sides are connected by a non-elastic rope 7. The non-elastic rope 7 is wound around the main shaft of the micro self-locking motor 9. The microprocessor transmits a control signal to the micro self-locking motor 9 in a unidirectional manner.

[0033] The multimodal sensor array module further includes at least one pair of bioelectrical impedance sensors.

[0034] The multimodal sensor array module further includes at least one blood oxygen concentration sensor.

[0035] The control host 2 is also provided with an alarm module, which includes at least one of a loudspeaker, a strobe LED light and a micro vibration motor.

[0036] The power supply module is a micro lithium battery or a piezoelectric power generation device or a body temperature difference power generation device.

[0037] The main shaft of the micro self-locking motor 9 is provided with a hand-tightening mechanism.

[0038] Working principle of this embodiment:

[0039] When worn, the micro-pressure sensors 10 within the multimodal sensor array module monitor the pressure distribution in key areas of the lower extremities (such as the course of the great saphenous vein and the gastrocnemius muscle belly) in real time. This data is transmitted via a unidirectional signal to the microprocessor in the control host 2. After analyzing the pressure data, the microprocessor synchronizes this information to the cloud or a user terminal (mobile phone / PC) via a communication module, helping doctors and patients monitor treatment progress. In this embodiment, the elastic stocking tube 1 covers at least one of the foot, calf, and thigh, with the toes exposed at the end. This allows for continuous monitoring of blood circulation in the patient's lower extremities, preventing inadvertent deterioration of the condition.

[0040] When the monitored pressure does not match the preset value, the microprocessor sends a control signal to the micro self-locking motor 9 to drive it to tighten or loosen the inelastic rope 7. By adjusting the spacing between the connecting pieces 8, the local pressure of the elastic stocking 1 on the leg is changed, such as Figures 6-8 As shown, the hand-tightening mechanism of the micro self-locking motor 9 supports manual fine-tuning to achieve precise adjustment of the pressure gradient, ensuring operability in power outages or emergency situations, and providing space for manual adjustment.

[0041] Bioelectrical impedance sensors and blood oxygen concentration sensors simultaneously collect physiological parameters such as lower limb blood flow status and tissue edema, and combine them with pressure data to form a comprehensive assessment, providing a basis for personalized treatment.

[0042] If abnormal pressure or excessive physiological parameters (such as blood flow obstruction) are detected, the alarm module (speaker / LED / vibration motor) of the control host 2 will immediately trigger an alarm to remind the user to intervene.

[0043] This embodiment effectively solves the problems of existing medical elastic stockings with non-adjustable pressure, single function, and lack of monitoring, and realizes personalized, data-based, and intelligent treatment.

[0044] Example 2: Please refer to Figures 3-5 , a smart medical compression stocking, which differs from Example 1 in that an opening is provided on the rear side of the elastic stocking tube 1 and passes through from bottom to top, and the opening is closed by a zipper 5. An anti-pinch gasket 4 of the same length as the zipper 5 is connected to one side of the opening, and the anti-pinch gasket 4 is located on the inner side of the zipper 5.

[0045] In this embodiment, the zipper 5 is arranged longitudinally along the rear opening of the stocking tube 1, enabling quick donning and doffing, while avoiding the high pressure associated with traditional stockings. A pinch-proof gasket 4, made of flexible silicone or fabric, is affixed to the inside of the zipper 5. This separates the skin from the sprocket teeth when the zipper is closed, preventing pinching and friction.

[0046] Due to the high elasticity required of medical compression stockings, donning and removing them can be difficult, especially for patients with limited limb or joint mobility. This embodiment allows patients to easily open and close the stocking using the zipper 5 without excessive stretching. The anti-pinch gasket completely prevents the zipper from pinching the skin, making it suitable for patients with diabetes or delicate skin. Once closed, the zipper 5 seamlessly fits the anti-pinch gasket 4, ensuring uniform pressure distribution across the opening area without compromising the gradient compression effect.

[0047] Example 3: Please refer to Figures 1 to 8 , a smart medical compression stocking, which differs from Example 1 in that the multimodal sensor array module also includes at least one temperature sensor.

[0048] An electric heating plate is also integrated on the inner side of the elastic stocking tube 1 .

[0049] In this embodiment, a temperature sensor monitors lower limb skin temperature in real time, feeding this data back to the microprocessor in the control host 2 to determine the local blood circulation status (e.g., a low temperature indicates insufficient blood flow). An electric heater integrated into the inner side of the stocking tube 1 is controlled by the microprocessor, which intelligently adjusts the heating power based on temperature data to achieve constant warmth.

[0050] In this embodiment, the gentle heating of the electric heating plate promotes vasodilation, enhances venous return, and relieves lower extremity coldness or venous congestion. The temperature sensor is linked to the heating system to prevent overheating and damage to the skin, ensuring treatment safety. Temperature change data can reflect treatment effectiveness (for example, the speed of temperature recovery after heating can be used to assess vascular function), providing a basis for doctors to adjust treatment plans.
