Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an adaptive tightness care package. Background Technology

[0002] Diabetic foot ulcers and other chronic wounds are common and serious complications in diabetic patients. Their treatment usually requires long-term use of nursing instruments for wound protection and fixation.

[0003] In existing technologies, nursing bandages used to secure dressings or braces often rely on manual adjustment of tightness. This adjustment method is somewhat subjective, and may result in poor local blood circulation due to excessive tightness, or ineffective fixation due to excessive looseness. Especially in diabetic patients, who often have peripheral neuropathy, their ability to perceive bandage pressure may be reduced, posing a challenge to the safety of traditional bandages.

[0004] Therefore, it is necessary to design an adaptive tightness care kit that can adaptively adjust the tightness according to changes in the degree of swelling at the affected area. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this utility model provides an adaptive tightness care pack. This adaptive tightness care pack can adaptively adjust the tightness of the straps according to the changes in the degree of swelling of the affected area, which improves the user experience of diabetic patients to a certain extent.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This utility model provides an adaptive tightness care package, comprising:

[0008] The assembly box has a first cavity and a second cavity separated by a partition structure inside;

[0009] The first cavity has an opening on its side wall that communicates with the outside; a baffle is provided on the outside of the opening that can be magnetically fixed to the side wall of the assembly box and used to seal the opening. The baffle is rotatably mounted on the side wall of the assembly box by means of a first rotating shaft provided on one side of the opening.

[0010] The second cavity houses a controller and a motor; a storage wheel is mounted on the motor's working shaft.

[0011] An elastic strap, one end of which passes through the cavity of the assembly box and is connected to the storage wheel, and the other end is installed on the side wall of the assembly box through a second rotating shaft;

[0012] Multiple strain gauges are disposed on the elastic strap along the longitudinal axis of the elastic strap, and the measurement direction of the strain gauges is parallel to the longitudinal axis of the elastic strap, for sensing the deformation of the elastic strap;

[0013] The strain gauge, motor, and controller are electrically connected to form a control system.

[0014] The control system is configured as follows:

[0015] When the average strain value fed back by multiple strain gauges is greater than a preset first threshold, the controller can control the motor to rotate in a first direction to drive the storage wheel to release the elastic strap to loosen the binding.

[0016] When the average strain value fed back by multiple strain gauges is less than the second threshold, the controller can control the motor to rotate in a second direction opposite to the first direction, in order to drive the storage wheel to wind and store the elastic strap to tighten the binding.

[0017] Furthermore, there are at least two strain gauges.

[0018] Furthermore, there are three strain gauges.

[0019] Furthermore, the spacing between adjacent strain gauges is not less than one-quarter of the total length of the elastic strap.

[0020] Furthermore, the strain gauge is sewn inside the elastic band.

[0021] Furthermore, the width of the elastic strap is not less than 2cm.

[0022] Furthermore, the thickness of the elastic strap is no more than 4 mm.

This structure facilitates access to and use of the internal medical supplies. It also incorporates a motor-driven storage wheel structure. The storage wheel is mounted on the motor's working shaft, allowing control of the elastic bandage's extension and retraction. Multiple strain gauges are arranged along the longitudinal axis of the elastic bandage, with their measurement direction parallel to the bandage axis, for sensing bandage deformation. A control system, formed by the electrical connection of the strain gauges, motor, and controller, is configured to control the motor's rotation based on the average strain value to adjust the bandage tightness. Overall, this invention enables automatic adjustment of the bandage tightness according to the degree of swelling at the affected area, providing a more comfortable binding experience and reducing the risk of complications caused by excessively tight or loose binding.

[0038] The embodiments of this utility model will be described in detail below.

[0039] This utility model embodiment discloses an adaptive tightness care package.

[0040] This utility model embodiment utilizes an overall structural design, with a partition structure inside the assembly box forming a first cavity and a second cavity. The first cavity has an opening on its side wall and is fitted with a magnetically secured baffle. The baffle is rotatably mounted via a first rotating shaft, facilitating access to and use of internal medical supplies. A controller and motor are installed in the second cavity. The motor's working shaft is connected to a storage wheel. Combined with the structure where one end of the elastic bandage is connected to the storage wheel and the other end is mounted via the second rotating shaft, automatic bandage release and retraction control is achieved. Multiple strain gauges are arranged along the longitudinal axis of the elastic bandage, with their measurement direction parallel to the bandage axis, for real-time sensing of bandage deformation. The strain gauges, motor, and controller are electrically connected to form a closed-loop control system. This system controls the motor's rotation direction based on the comparison between the average strain value fed back from the multiple strain gauges and a preset threshold, driving the storage wheel to release or wind the bandage. This configuration dynamically adjusts the bandage tightness to adapt to changes in swelling at the affected area, providing a more stable binding effect and reducing the risk of local blood circulation problems or fixation failure due to excessively tight or loose binding. Specific details are as follows:

[0041] Assembly box 1 is the main supporting structure of this utility model. Its interior is divided into a first cavity 11 and a second cavity 12 by a partition structure. The function of assembly box 1 is to accommodate and fix other components, and to provide structural stability and protection. In this embodiment, assembly box 1 is manufactured using injection molding, and the material is medical-grade ABS plastic. In other embodiments, assembly box 1 can also be made of aluminum alloy using die casting, or of polycarbonate using thermoforming. These materials provide sufficient mechanical strength while ensuring lightweight design.

[0042] The separation structure between the first cavity 11 and the second cavity 12 is achieved by an internal partition. The partition is integrally formed with the assembly box 1 and has a thickness of 2-5mm, preferably 3mm. In other embodiments, the partition can also be installed inside the assembly box 1 by means of snap-fit ​​connection or screw fixing.

[0043] The first cavity 11 is used to store medical supplies, and its side wall has an opening 111 communicating with the outside. In this embodiment, the opening 111 is rectangular; in other embodiments, the opening 111 may also be circular or elliptical. A baffle 112 is provided on the outside of the opening 111, which can be magnetically fixed to the side wall of the assembly box 1 and is used to seal the opening 111. The function of the baffle 112 is to cover the opening 111 when not in use, preventing dust and foreign objects from entering the internal cavity. The baffle 112 is rotatably mounted to the side wall of the assembly box 1 by means of a first pivot 113 provided on one side of the opening 111. The function of the first pivot 113 is to provide a pivot point for the rotation of the baffle 112, so that it can be easily opened and closed. In this embodiment, the baffle 112 is magnetically fixed to the galvanized steel sheet of the side wall of the assembly box 1 by embedded neodymium magnets; in other embodiments, the baffle 112 may also be fixed by a spring clip mechanism. The baffle 112 is made using injection molding and is covered with a medical-grade silicone layer to enhance sealing and user comfort. The baffle 112 is slightly larger than the opening 111, with an overlap of 2-3mm to ensure an effective seal.

[0044] The second cavity 12 houses a controller and a motor 2. The controller is microprocessor-based and includes a built-in logic control program and signal processing circuitry. Its function is to process the signals from the strain gauge 4 and control the operating logic of the motor 2. In this embodiment, the motor 2 is a DC geared motor; in other embodiments, it can be a stepper motor or a servo motor. A receiving wheel 21 is mounted on the working shaft of the motor 2. The receiving wheel 21 winds and stores the elastic strap 3, ensuring smooth operation during the strap winding and unwinding process. The motor 2 drives the receiving wheel 21 to rotate, thereby winding and unwinding the elastic strap 3.

[0045] One end of the elastic bandage 3 passes through the cavity of the assembly box 1 and is connected to the storage wheel 21, while the other end is mounted on the side wall of the assembly box 1 via the second rotating shaft 114. The function of the elastic bandage 3 is to be wrapped around the patient's affected area, providing fixation and support. The function of the second rotating shaft 114 is to fix the end of the elastic bandage 3 and allow it to rotate within a certain range to avoid twisting and wear. In this embodiment, the elastic bandage 3 is made of medical elastic fabric, and its composition is a cotton-nylon blend; in other embodiments, the elastic bandage 3 may also be made of silicone or rubber. In this embodiment, the elastic bandage 3 is connected to the storage wheel 21 by riveting; in other embodiments, it may also be connected by adhesive bonding.

[0046] In this embodiment, the elastic bandage 3 is 3cm wide; in other embodiments, the elastic bandage 3 may be 2cm or 4cm wide. A wider bandage can distribute the binding pressure, reduce the pressure on the skin, and improve comfort. The width parameter is based on ergonomic design to accommodate different limb circumferences. For example, for a calf circumference of 200-400mm, a bandage width of 3cm can provide sufficient coverage area and more even pressure distribution.

[0047] In this embodiment, the elastic bandage 3 is 3 mm thick; in other embodiments, the thickness of the elastic bandage 3 may be 2 mm or 4 mm. A thinner bandage increases flexibility and fit, making it easier to wear and adapt to the contours of different body parts; the thickness parameter takes into account the needs for breathability and lightweighting to improve patient compliance.

[0048] Multiple strain gauges 4 are arranged on the elastic bandage 3 along its longitudinal axis, and the measurement direction of the strain gauges 4 is parallel to the longitudinal axis of the elastic bandage 3, for sensing the deformation of the elastic bandage 3. The function of the strain gauges 4 is to detect the tensile strain of the elastic bandage 3, thereby reflecting the tightness of the bandage and the pressure applied to the affected area.

[0049] In this embodiment, the strain gauge 4 is a resistive strain gauge; in other embodiments, the strain gauge 4 can also be a capacitive sensor. In this embodiment, the strain gauge 4 is glued and sewn inside the elastic band 3 with adhesive, which can protect the strain gauge 4 from external wear and contamination, while ensuring close contact with the elastic band 3; in other embodiments, the strain gauge 4 can also be directly molded onto the elastic band 3 by printing circuitry.

[0050] In this embodiment, three strain gauges 4 are used; in other embodiments, there may be two, four, or other numbers of strain gauges 4. Multiple strain gauges 4 can improve the accuracy and reliability of the measurement, and reduce the influence of local errors by averaging. This multi-point measurement mechanism helps to overcome the reading deviations that may be caused by local deformation of the strap or external interference of a single-point sensor.

[0051] Three strain gauges 4 can be evenly distributed along the elastic band 3 to provide more comprehensive deformation data and enhance the system's ability to perceive the overall state of the band. For example, they can be arranged in three sections along the band's length—front, middle, and rear—to cover potentially high-strain areas. In this embodiment, the spacing between adjacent strain gauges 4 is set to one-third of the total length of the elastic band 3; in other embodiments, the spacing between adjacent strain gauges 4 can also be one-quarter. This spacing ensures that the strain gauges 4 cover the critical areas of the band, avoiding data overlap or monitoring blind spots, thereby improving the representativeness of the overall band tension assessment.

[0052] The strain gauges 4, motor 2, and controller are electrically connected to form a control system. The control system is configured such that: when the average strain value fed back by the multiple strain gauges 4 is greater than a preset first threshold, the controller can control the motor 2 to rotate in a first direction to drive the storage wheel 21 to release the elastic strap 3, thus loosening the binding; when the average strain value fed back by the multiple strain gauges 4 is less than a preset second threshold, the controller can control the motor 2 to rotate in a second direction opposite to the first direction, thus driving the storage wheel 21 to wind and store the elastic strap 3, thus tightening the binding. The function of the control system is to achieve automatic adjustment and dynamic response of the strap tension.

[0053] The first and second thresholds are set based on clinical data and represent the ideal range of binding pressure. The first threshold is used to control the loosening of the binding, and the second threshold is used to control the tightening of the binding. The range of the first threshold is 400-500 με (microstrain), preferably 450 με; the range of the second threshold is 100-200 με (microstrain), preferably 150 με.

[0054] Overall, this invention combines a motor 2, an elastic bandage 3, and multiple strain gauges 4, enabling it to automatically adjust the bandage tightness based on the degree of swelling at the affected area. The use of a closed-loop control mechanism involving multi-point strain monitoring and motor-driven tensioning allows for dynamic optimization of the elastic bandage 3's tension, avoiding the problems of excessive tightness or looseness caused by improper manual adjustment in traditional bandages. In the care of diabetic foot ulcers and other chronic wounds, this structure provides a more stable binding effect, reduces the risk of local blood circulation obstruction or fixation failure, and enhances comfort and durability through material selection and parameter design.

[0055] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
