Abstract
Description
Technical Field
[0001] The present invention relates to the field of limb position technology for orthopedic patients, and specifically to a wearable limb position fixation monitoring device for orthopedic patients.
Background Art
[0002] In the rehabilitation treatment process of orthopedic diseases, the accurate fixation and position monitoring of the patient's limb position play a decisive role in the recovery effect. Conventional limb position fixation methods (such as plaster bandages and ordinary protectors) mainly hold the limb position by physical restraint, but their structure is relatively fixed, and it is difficult to make flexible adjustments according to the needs of different recovery stages of patients and the differences in individual limb sizes. This not only impairs the comfort of the patient, but also the inaccuracy of fixation may cause inhibition of the recovery process and secondary injuries. Furthermore, existing monitoring means often rely on regular manual inspections by medical staff, lacking real-time performance and continuity. If the patient's limb position deviates during non-inspection hours, it is impossible to detect and correct it immediately, greatly impairing the rehabilitation effect and prolonging the recovery period. Although some smart monitoring devices have been introduced into the medical field, these are complex in structure, high in cost, and single in function, and cannot effectively integrate the functions of limb position fixation, real-time position monitoring, and abnormal alarm, making it difficult to meet the actual clinical needs.

Avoid monitoring errors caused by fixed angle deviation. 2. Flexible adaptation to different patient needs: Through the combined design of the adjustment slide groove (5) and the wearable mounting block (6), the mounting position of the infrared sensor (7) can be adjusted according to the limb size and recovery stage of the patient. Realize individualized monitoring and expand the application range of the device. 3.

DETAILED DESCRIPTION OF THE INVENTION
[0012] Hereinafter, with reference to the drawings of the embodiments of the present invention, the technical solution in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, it goes without saying that any other embodiments obtained by those of ordinary skill in the same technical field without creative efforts are included within the scope of the claims of the present invention.
EXAMPLE
[0013] As shown in FIGS. 1 to 4, the wearable orthopedic patient limb position fixing and monitoring device of the present invention includes the following components. The first fixing plate 1 and the second fixing plate 2, which are the basic frame parts of the monitoring device. The second fixing plate 2 is rotatably connected to one side of the first fixing plate 1 (prior art), and can be fixed at a corresponding angle according to the limb shape and angle requirements of the patient. A flexible pad layer is provided on the inner surfaces of both fixing plates to provide a comfortable wearing feeling for the patient. To prevent skin compression and damage caused by long-term wearing. Further, a plurality of limb fixing bands are provided on the fixing sides of the first fixing plate 1 and the second fixing plate 2 to prevent dropping during use.
[0014] The arc-shaped guide part 3 and the guide sleeve 4. The arc-shaped guide part 3 is fixedly connected to the rotating edge of the second fixing plate 2. The guide sleeve 4 is fixedly installed in the middle of the first fixing plate 1. The guide sleeve 4 has an arc passage that coincides with the movement locus of the arc-shaped guide part 3, and its center coincides with the rotation axis of the first fixing plate 1 and the second fixing plate 2. Thereby, when the second fixing plate 2 rotates, the arc-shaped guide part 3 can smoothly move in the guide sleeve 4, providing a high-precision movement locus reference for subsequent displacement detection.
[0015] Displacement detection mechanism. It includes at least one set of infrared sensors 7 installed on the surface of the arc-shaped guide component 3. The infrared sensor 7 detects the distance signal between the arc-shaped guide component 3 and the guide sleeve 4 in real time, and determines the presence or absence of limb deviation by analyzing the distance change. An adjustment slide groove 5 along the arc passage is provided on the side wall of the arc-shaped guide component 3, and the displacement detection mechanism is fixed at different positions of the adjustment slide groove 5 through the mounting type attachment block 6. This enables the position adjustment of the infrared sensor 7 according to the limb size and recovery stage of the patient. The adjustment slide groove 5 is provided with a scale display indicating the distance to ensure an intuitive understanding of the mounting position and distance information and the installation accuracy. Wireless alarm mechanism 8: Communicatively connected to the displacement detection mechanism. It consists of a signal processing mechanism and a wireless transmission mechanism. The signal processing mechanism generates a trigger signal when the infrared sensor 7 detects a deviation from the set position of the arc-shaped guide component 3. The wireless transmission mechanism transmits the trigger signal to an external alarm device (such as a medical staff's portable terminal, ward alarm system, etc.) to enable medical staff to immediately grasp the abnormality. At the same time, the wireless alarm mechanism 8 incorporates a vibration motor and activates a local vibration alarm synchronously when the trigger signal is generated to alert the patient himself.
[0016] (Effect of the invention) The first fixing plate 1 and the second fixing plate 2 are fixed to the patient's limb through a rotational connection. After being fixed at an appropriate angle (prior art), they are fixed with bolts or the like. The arc-shaped guide component 3 is fixed to the rotational edge of the second fixing plate 2, and its movement locus is aligned with the arc passage of the guide sleeve 4 on the first fixing plate 1. When the patient's limb position deviates, the second fixing plate 2 drives the arc-shaped guide component 3 to move within the guide sleeve 4. The infrared sensor 7 on the surface of the arc-shaped guide component 3 detects the distance signal from the guide sleeve 4 in real time. When the distance exceeds a predetermined range (deviation from the set position of the arc-shaped guide component 3), the displacement detection mechanism transmits a signal to the wireless alarm mechanism 8. After receiving the abnormal signal, the signal processing mechanism of the wireless alarm mechanism 8 generates a trigger signal, notifies the patient through a local alarm by the built-in vibration motor, and notifies an external alarm device through the wireless transmission mechanism. This realizes the real-time monitoring and abnormal alarm of the patient's limb position.
[0017] (Remarks) The technical scope of the present invention is not limited to the above description. Those skilled in the art can make various modifications and corrections to the above embodiments without departing from the technical idea of the present invention. It is claimed that all such modifications and corrections belong to the protection scope of the present invention.
