Description

Technical Field

[0001] The present invention relates to the technical field of venous monitoring, and specifically to a wearable lower limb venous thrombosis monitoring device. Background Art

[0002] A wearable lower limb venous thrombosis monitoring device is a device designed specifically for monitoring the formation of lower limb venous thrombosis and has important clinical application value. It mainly monitors physiological parameters such as blood flow in the lower limbs, venous pressure, and temperature changes in real time to help detect the formation of thrombosis at an early stage and prevent serious complications caused by thrombosis such as pulmonary embolism. This type of device collects data through a sensor system (such as pressure, temperature, optical sensors, etc.) and analyzes the thrombosis risk through a data processing unit, triggering an alarm in a timely manner to remind the patient to seek medical treatment. It has the advantages of non-invasiveness, convenience, and real-time performance. Different from traditional ultrasound or CT examinations, the wearable device can continuously monitor for 24 hours, reducing patient discomfort and is suitable for high-risk patients who are bedridden for a long time or after surgery. In addition, the device is usually equipped with a communication module to support remote data transmission, facilitating doctors to track the patient's health status in real time;

[0003] For example, the wearable lower limb venous thrombosis monitoring device disclosed in the authorized publication number CN221106235U includes a medical elastic stocking body, more than one blood flow detector, more than one venous pressure detector, and a remote controller. The blood flow detector and the venous pressure detector are respectively arranged on the medical elastic stocking body, and the blood flow detector and the venous pressure detector are respectively in signal communication with the remote controller. A display screen is provided on the remote controller. The remote controller receives the information fed back by the blood flow detector and the venous pressure detector and displays it on the display screen, combining the process of pressurizing the medical elastic stocking body to treat lower limb venous thrombosis with the blood flow and blood pressure monitoring processes, and enabling real-time monitoring information display, sound and light alarm, and evaluation report summary on the remote controller, facilitating the long-term wearing, treatment, and prevention processes. However, in the above technical solution, during use, the medical elastic stocking body is mainly used for wearing and the detection points of the blood flow detector and the venous pressure detector are fixed. In the actual monitoring process, synchronous detection at multiple positions is often adopted, that is, the inner thigh (femoral vein), the back of the calf (posterior tibial / peroneal vein). At this time, the above device requires the user to frequently adjust the detection points by themselves, thereby continuously adjusting the wearing position of the medical elastic stocking body. The medical elastic stocking body is located inside the trousers, and the wearing of the medical elastic stocking is relatively tight and not easily adjusted at will. It is very difficult for the user to quickly adjust the detection position during different activities, especially during daily activities such as walking, running, or sitting. The fixity of the stocking body and the flexibility of position adjustment are insufficient, resulting in inconvenience for the user during use. Summary of the Invention

[0004] The object of the present invention is to provide a wearable lower limb venous thrombosis monitoring device. The end of the upper notch-type leg sleeve is rotatably connected to the middle notch ring by a ring groove rotating connection part, and the middle notch ring is connected to the lower notch-type leg sleeve through a snap spring quick-release structure and an elastic connection band. After the upper notch-type leg sleeve and the lower notch-type leg sleeve are adjusted to the proper use positions through the middle notch ring and the elastic connection band, they are worn on the user's thigh and calf through a tightening structure. And a double-winged arc-shaped semi-open sliding sleeve slides in the leg sleeve so that the thrombus elasticity detection sensor can be quickly adjusted to the thrombus detection position, thus solving the problems raised in the above-mentioned background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions: A wearable lower limb venous thrombosis monitoring device, comprising:

[0006] An upper notch-type leg sleeve, one end of the upper notch-type leg sleeve is provided with a middle notch ring, and a ring groove rotating connection part for maintaining a rotating connection is arranged between the opposite ends of the upper notch-type leg sleeve and the middle notch ring.

One end of the middle notch ring is installed with an elastic connection band through the snap spring quick-release structure, and the end of the elastic connection band away from the middle notch ring is installed with a lower notch-type leg sleeve. The lower notch-type leg sleeve is used for sleeving on the user's calf, and the upper notch-type leg sleeve is used for sleeving on the user's thigh;

[0007] A tightening structure, the tightening structure is installed at the opening positions of the upper notch-type leg sleeve, the middle notch ring and the lower notch-type leg sleeve. A double-winged arc-shaped semi-open sliding sleeve is slidably installed inside the upper notch-type leg sleeve and the lower notch-type leg sleeve. A thrombus elasticity detection sensor is installed on the outer wall of one side of the double-winged arc-shaped semi-open sliding sleeve close to the central axis of the upper notch-type leg sleeve and the lower notch-type leg sleeve. A central controller is installed on one side of the bottom end of the lower notch-type leg sleeve, a display screen is installed at the bottom end of the central controller, and the input end of the display screen is electrically connected to the output end of the central controller. The output end of the thrombus elasticity detection sensor is electrically connected to the input end of the central controller.

[0008] Preferably, the upper notch-type leg sleeve, the middle notch ring and the lower notch-type leg sleeve are all made of components of medical silicone material, and the thickness of the upper notch-type leg sleeve and the lower notch-type leg sleeve is 5 mm to 10 mm.

[0009] In the above solution, medical silicone has good softness and elasticity, and can better fit the user's skin and body shape. Especially in the case of long-term wearing, the silicone material can effectively relieve the sense of compression and improve the wearing comfort. And the thickness of 5 mm to 10 mm is appropriate, which can not only provide sufficient supporting force to stabilize the leg sleeve, but also maintain moderate softness to avoid discomfort caused by being too hard or too soft.

[0010] Preferably, the ring groove rotating connection part includes a dovetail annular groove provided at the opening position of one end of the upper notch - type leg sleeve, and a dovetail arc - shaped flange integrally formed at one end of the middle - placed missing ring close to the upper notch - type leg sleeve. The dovetail arc - shaped flange and the dovetail annular groove are mutually engaged and maintained in relative sliding connection.

[0011] In the above - mentioned solution, when the middle - placed missing ring, the snap - ring quick - release structure, the elastic connection band, and the lower notch - type leg sleeve are rotationally adjusted with the upper notch - type leg sleeve through the ring groove rotating connection part, the dovetail arc - shaped flange rotates in the dovetail annular groove at the end of the upper notch - type leg sleeve. The design of the dovetail annular groove and the dovetail arc - shaped flange forms a snap - fastener structure, so that the upper notch - type leg sleeve and the middle - placed missing ring can be firmly connected during the use of the device.

[0012] Preferably, the tightening structure includes a watchband and a watch buckle. The watchband is fixed on one side of the top - notch of the upper notch - type leg sleeve, the middle - placed missing ring, and the lower notch - type leg sleeve, and the watch buckle is fixed on the other side of the top - notch of the upper notch - type leg sleeve, the middle - placed missing ring, and the lower notch - type leg sleeve.

[0013] In the above - mentioned solution, the tightening structure adopts a structure similar to that of a watchband, and users can adjust the tightness of the device according to their own needs to avoid being too tight or too loose.

[0014] Preferably, several equally - spaced first convex parts are integrally formed at one end of the middle - placed missing ring away from the upper notch - type leg sleeve. The snap - ring quick - release structure is installed on the first convex parts. Several equally - spaced second convex parts are integrally formed at one end of the lower notch - type leg sleeve close to the middle - placed missing ring. One end of the elastic connection band extends into the interior of the second convex parts and is fixedly connected to the second convex parts.

[0015] Preferably, the snap - ring quick - release structure includes a U - shaped connecting seat fixed at one end of the first convex part and a T - shaped shaft rod inserted and installed inside the U - shaped connecting seat. One end of the T - shaped shaft rod penetrates to the outside of the U - shaped connecting seat and is equipped with an R - type snap - ring.

[0016] Preferably, a hollow ring sleeve is integrally formed at one end of the elastic connection band away from the second convex part. The hollow ring sleeve and the T - shaped shaft rod are sleeved with each other. A through - hole for inlaying the R - type snap - ring is provided on the surface of one end of the T - shaped shaft rod.

[0017] In the above - mentioned solution, the user uses tweezers to draw out the R - type snap - ring from the through - hole at the end of the T - shaped shaft rod, so that the R - type snap - ring no longer hinders the withdrawal of the T - shaped shaft rod.

[0018] Preferably, hollow parts are provided on the outer walls on both sides of the upper notch - type leg sleeve and the lower notch - type leg sleeve, and the double - wing - type arc - shaped half - open sliding sleeve is slidably installed between two hollow parts in the same Y - axis direction.

[0019] Preferably, inverted L-shaped wing edges are provided on both sides of the top end of the double-wing arc-shaped semi-open sliding sleeve. The inverted L-shaped wing edges are in sliding fit with the hollowed-out part. A T-shaped anti-disengagement seat is integrally formed at the bottom end of the double-wing arc-shaped semi-open sliding sleeve. Linear sliding grooves for the X-axis sliding of the T-shaped anti-disengagement seat are provided at the bottom ends of the upper-notch leg sleeve and the lower-notch leg sleeve.

[0020] Preferably, dovetail-shaped ribs are installed on the left and right inner walls of the linear sliding groove. Dovetail-shaped grooves are provided on the left and right outer walls of the T-shaped anti-disengagement seat. The dovetail-shaped ribs are in sliding fit with the dovetail-shaped grooves.

[0021] In the above solution, the left and right outer walls of the T-shaped anti-disengagement seat are in sliding fit with the dovetail-shaped ribs inside the linear sliding groove. At this time, the double-wing arc-shaped semi-open sliding sleeve allows the thrombus elasticity detection sensor to slide inside the leg sleeve so as to be adjusted to the optimal monitoring position, enabling the sensor to slide precisely as needed.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows: The wearable lower limb venous thrombus monitoring device is provided with structures such as an upper-notch leg sleeve, a ring groove rotation connection part, a middle-notch ring, an elastic connection band, etc. that cooperate with each other. The middle-notch ring is connected to the lower-notch leg sleeve through a snap fastener structure and an elastic connection band. After the upper-notch leg sleeve and the lower-notch leg sleeve adjust the use position through the middle-notch ring and the elastic connection band, they are worn on the user's thigh and calf through a tightening structure. Moreover, the double-wing arc-shaped semi-open sliding sleeve slides in the leg sleeve so that the thrombus elasticity detection sensor can be quickly adjusted to the thrombus detection point. Among them, the structure combining the upper-notch leg sleeve and the lower-notch leg sleeve, together with the rotational connection of the middle-notch ring, can effectively simplify the wearing and adjustment process. The user only needs to adjust the positions of the middle-notch ring and the elastic connection band to quickly change the position of the device and accurately dock to different venous detection points. This design greatly reduces the trouble in the wearing and adjustment process of the traditional device, enabling the user to complete the position adjustment of the monitoring device in a relatively short time, thereby improving the usability of the device and the dependence of the user. And the combination of the upper-notch leg sleeve and the lower-notch leg sleeve, through the adjustment of the middle-notch ring and the elastic connection band, enables the monitoring device to accurately dock to specific detection parts such as the thigh and calf. When the position of the device is stable, the accuracy of the sensor is guaranteed, avoiding the detection deviation or false alarm that may occur in the traditional device. The user also does not need to frequently adjust and operate, and can ensure that the device always remains in the optimal monitoring position, thereby improving the accuracy of thrombus monitoring.

[0023] Secondly, through the stabilizing effect of the tightening structure on the legs, the device can always maintain the correct position without sacrificing comfort, reducing the discomfort and local compression caused by long-term wearing. Users can also easily adjust the position of the detection device in daily life without the help of others, facilitating the monitoring of different parts and enhancing its independence and convenience of use. That is, the design of the middle-position missing ring and the elastic connecting band makes the adjustment of the device convenient and fast, and users can quickly adjust the position according to their needs during daily activities. Finally, after using this design, users can perform synchronous detection at multiple key parts, such as the femoral vein and the posterior tibial vein on the back of the calf. By adjusting to these key points, not only can more detection areas be covered, but also signs of thrombosis can be detected earlier, reducing the risk of more serious complications caused by thrombosis.

The input end of the display screen 12 is electrically connected to the output end of the central controller 11, and the output end of the thromboelastography sensor 10 is electrically connected to the input end of the central controller 11.

[0040] Embodiment 2, on the basis of Embodiment 1, is given by Figure 7 and Figure 8 The notched design of the upper notched leg sleeve 1, the middle ring with notch 2, and the lower notched leg sleeve 3 enables the user to wear the device more easily. The notch design not only facilitates putting on and taking off but also ensures comfort during wearing, without causing compression to blood circulation. At the same time, the tightening structure of the leg sleeve helps the device to be firmly fixed on the leg and will not be displaced due to movement during use, ensuring the stability of monitoring;

[0041] The upper notched leg sleeve 1, the middle ring with notch 2, and the lower notched leg sleeve 3 are all made of components of medical silicone material. The thickness of the upper notched leg sleeve 1 and the lower notched leg sleeve 3 is 5 mm to 10 mm;

[0042] The middle ring with notch 2 is used to connect the opposite ends of the upper notched leg sleeve 1 and the lower notched leg sleeve 3, and ensures that the lower notched leg sleeve 3 can be freely adjusted through the middle ring with notch 2 and the ring groove rotating connection part 7, facilitating the flexible adjustment of the lower notched leg sleeve 3 and the double-winged arc-shaped semi-open sliding sleeve 9 and the thromboelastography sensor 10 inside it according to the detection needs and the movement of the leg, avoiding discomfort or a sense of tightness of the device caused by long-term wearing.

[0043] The ring groove rotating connection part 7 includes a dovetail annular notch 701 provided at the opening position of one end of the upper notched leg sleeve 1 and a dovetail arc-shaped flange 702 integrally formed at one end of the middle ring with notch 2 close to the upper notched leg sleeve 1. The dovetail arc-shaped flange 702 is engaged with the dovetail annular notch 701 and maintains a relative sliding connection;

[0044] When the middle missing ring 2, the snap spring quick-release structure 6, the elastic connection band 5, and the lower notch-type leg sleeve 3 are rotationally adjusted with the upper notch-type leg sleeve 1 through the annular groove rotating connection part 7, the dovetail arc-shaped flange 702 rotates in the dovetail annular notch 701 at the end of the upper notch-type leg sleeve 1. The design of the dovetail annular notch 701 and the dovetail arc-shaped flange 702 forms a snap structure, enabling the upper notch-type leg sleeve 1 and the middle missing ring 2 to be firmly connected during the use of the device, effectively preventing the connection part from loosening or shifting due to leg movement;

[0045] The tightening structure 4 includes a watchband and a buckle. The watchband is fixed on one side of the top-notch of the upper notch-type leg sleeve 1, the middle missing ring 2, and the lower notch-type leg sleeve 3, and the buckle is fixed on the other side of the top-notch of the upper notch-type leg sleeve 1, the middle missing ring 2, and the lower notch-type leg sleeve 3. The tightening structure 4 adopts a similar structure to a watchband, including an adjustment band or an adjustment buckle. Users can adjust the tightness of the device according to their own needs to avoid being too tight or too loose; The elastic connection band 5 functions to connect the lower notch-type leg sleeve 3 and the middle missing ring 2, keeping the two leg sleeves connected;

[0046] Example three, based on Example two, is given by Figure 9 and Figure 10 A plurality of equally spaced first convex portions 201 are integrally formed at one end of the middle missing ring 2 away from the upper notch-type leg sleeve 1. The snap spring quick-release structure 6 is installed on the first convex portions 201. A plurality of equally spaced second convex portions 301 are integrally formed at one end of the lower notch-type leg sleeve 3 close to the middle missing ring 2. One end of the elastic connection band 5 extends into the interior of the second convex portions 301 and is fixedly connected to the second convex portions 301;

[0047] The snap spring quick-release structure 6 eliminates the need for complex connecting parts such as screws and fasteners in traditional devices. It not only reduces the weight of the device, making it more convenient to wear, but also simplifies the production and assembly process and reduces the manufacturing cost. The snap spring quick-release structure 6 includes a U-shaped connection seat 601 fixed at one end of the first convex portion 201 and a T-shaped shaft rod 602 inserted and installed inside the U-shaped connection seat 601. One end of the T-shaped shaft rod 602 penetrates to the outside of the U-shaped connection seat 601 and is installed with an R-shaped snap spring 604. A hollow ring sleeve 603 is integrally formed at one end of the elastic connection band 5 away from the second convex portion 301. The hollow ring sleeve 603 and the T-shaped shaft rod 602 are sleeved with each other. A through hole 605 for embedding the R-shaped snap spring 604 is provided on the surface of one end of the T-shaped shaft rod 602;

[0048] When the user needs to disconnect the connection between the elastic connecting band 5 and the middle missing link 2, the user uses tweezers to extract the R-shaped snap spring 604 from the through hole 605 at the end of the T-shaped shaft rod 602, so that the R-shaped snap spring 604 no longer hinders the withdrawal of the T-shaped shaft rod 602. Then the staff withdraws the T-shaped shaft rod 602 from the U-shaped connecting seat 601 and the hollow ring sleeve 603. At this time, the end of the elastic connecting band 5 is separated from the U-shaped connecting seat 601 and the T-shaped shaft rod 602, and then the connection restriction between the upper notched leg sleeve 1 and the lower notched leg sleeve 3 is disconnected. The snap spring quick-release structure 6 enables the user to adjust the wearing method of the leg sleeve according to their own body type or usage environment, so as to improve comfort and applicability.

[0049] Embodiment 4 is based on Embodiment 3 and is given by Figure 11 and Figure 12 On the outer walls on both sides of the upper notched leg sleeve 1 and the lower notched leg sleeve 3, there are provided hollowed-out portions 8. By providing the hollowed-out portions 8 on the outer peripheral surfaces of the upper notched leg sleeve 1 and the lower notched leg sleeve 3, the contact area between the leg sleeve and the user's leg is reduced, and the pressure and restriction of the leg sleeve on the user's leg are reduced.

[0050] The double-winged arc-shaped semi-open sliding sleeve 9 is slidably installed between two hollowed-out portions 8 in the same Y-axis direction. On both sides of the top end of the double-winged arc-shaped semi-open sliding sleeve 9, there are provided inverted L-shaped wing edges 901. The inverted L-shaped wing edges 901 are in sliding fit with the hollowed-out portions 8. At the bottom end of the double-winged arc-shaped semi-open sliding sleeve 9, a T-shaped anti-disengagement seat 902 is integrally formed. At the bottom ends of the upper notched leg sleeve 1 and the lower notched leg sleeve 3, there are provided linear chutes 13 for the X-axis sliding of the T-shaped anti-disengagement seat 902. On the left and right inner walls of the linear chutes 13, there are installed dovetail ribs 14. On the left and right outer walls of the T-shaped anti-disengagement seat 902, there are provided dovetail grooves 903. The dovetail ribs 14 and the dovetail grooves 903 are in sliding fit.

[0051] The two outer walls of the T-shaped anti-disengagement seat 902 are in sliding fit with the dovetail ribs 14 inside the linear chutes 13 through the dovetail grooves 903. At this time, the double-winged arc-shaped semi-open sliding sleeve 9 allows the thrombus elastic detection sensor 10 to slide inside the leg sleeve, so as to be adjusted to the best monitoring position, enabling the sensor to slide precisely according to needs, and avoiding the problem that the monitoring effect is affected due to the inappropriate position of the sensor in the existing device.

[0052] The T-shaped anti-disengagement seat 902 prevents the double-wing arc-shaped semi-open sliding sleeve 9 from disengaging from the upper notched leg sleeve 1 or the lower notched leg sleeve 3. At the same time, the inverted L-shaped wing edge 901 further slidably cooperates with the hollowed-out part 8, so that the double-wing arc-shaped semi-open sliding sleeve 9 and the leg sleeve can be more firmly connected during movement, avoiding loosening or falling off of the accessories due to external force or vibration. Moreover, the arc-shaped design of the double-wing arc-shaped semi-open sliding sleeve 9 enables the leg sleeve to slide more smoothly when adjusting the position, thereby easily adjusting the position or configuration of the leg sleeve to adapt to different treatment needs and enhancing the wearing comfort.

[0053] Before using the device in the embodiments of the present application, it is first necessary to ensure that all components are in a normal state, the battery power in the central controller 11 is sufficient, and the user checks the working state of the device through the central controller 11 and views the prompt information on the display screen. At the same time, it is necessary to ensure that all components are firmly connected, especially the configuration of the double-wing arc-shaped semi-open sliding sleeve 9 and the double-wing thromboelastogram detection sensor 10; the user wears the upper-notch leg sleeve 1 and the lower-notch leg sleeve 3 to the appropriate positions on the thigh and calf respectively. The two leg sleeves are designed with a notch structure, which is convenient for the user to quickly wear, and at the same time can ensure the stability and comfort of the device. At this time, the user adjusts the leg sleeves to the thigh and calf parts to ensure that the openings of the two can accurately align with the leg structure. During the wearing process, the user should ensure that the leg sleeves do not affect blood circulation and avoid a sense of restraint. The upper and lower structures of the device are designed so that the leg sleeves can be appropriately adjusted according to the user's body type to ensure comfort and effectiveness; after the upper-notch leg sleeve 1 and the lower-notch leg sleeve 3 are worn, the user uses the middle-notch ring 2 and the elastic connection band 5 to adjust the position of the lower-notch leg sleeve 3, that is, rotates the middle-notch ring 2 and the lower-notch leg sleeve 3 through the ring groove rotating connection part 7, so that the lower-notch leg sleeve 3 rotates around the user's calf until the double-wing arc-shaped semi-open sliding sleeve 9 and the thromboelastogram detection sensor 10 in the middle-notch ring 2 are adjusted to parts such as the posterior tibial vein on the back of the calf, and the double-wing arc-shaped semi-open sliding sleeve 9 and the thromboelastogram detection sensor 10 in the upper-notch leg sleeve 1 are located at the femoral vein part on the inner side of the thigh. By allowing the sensor to move on the user's leg, it can be accurately adjusted to the ideal position to avoid errors caused by improper sensor position; once the upper-notch leg sleeve 1 and the lower-notch leg sleeve 3 are adjusted to the appropriate positions, the user uses the tightening structure 4 to tighten the upper-notch leg sleeve 1, the middle-notch ring 2, and the lower-notch leg sleeve 3 on the leg and ensure the stability of the device. The user can adjust the tightening degree according to their own needs to avoid discomfort caused by being too loose or too tight. Subsequently, the user starts the thrombus monitoring function through the central controller 11, and the display screen 12 on the central controller 11 displays the real-time monitoring data of the thromboelastogram detection sensor 10, including the working state of the thromboelastogram detection sensor 10, the completed monitoring time, the detected thrombus elasticity data, etc. In daily operations, the user does not need to frequently turn the device on or off. Through the display screen 12, the user can quickly view the current detection state, and at the same time the device automatically records the data; when performing daily activities, the user may need to adjust the monitoring device according to changes in standing, walking or sitting postures. For example, when the user changes from standing to sitting, the blood flow in the legs may change, and it may be necessary to slightly adjust the position of the thromboelastogram detection sensor 10 to ensure accurate monitoring. At this time, the user only needs to gently pull the double-wing arc-shaped semi-open sliding sleeve 9, so that the double-wing arc-shaped semi-open sliding sleeve 9 slides in the upper-notch leg sleeve 1 or the lower-notch leg sleeve 3, thus realizing fast and convenient adjustment;After the monitoring is completed, the user stops the monitoring function through the central controller 11 and the display screen 12, turns off the device, removes the device from the leg, disassembles the device as needed, cleans it, and stores it in a suitable place.
