Description

Technical Field

[0001] This utility model relates to the technical field of pressure detection devices, specifically a strap pressure detection device. Background Technology

[0002] Lymphedema refers to the accumulation of soft tissue fluid on the skin surface due to obstructed lymphatic drainage in certain parts of the body, resulting in subcutaneous fibrous connective tissue hyperplasia and fat hardening after repeated infections. Currently, the most widely used and effective treatment internationally is comprehensive lymphedema treatment (CDT), also known as multi-layer low-elasticity elastic bandage ligation. Multi-layer low-elasticity elastic bandage ligation involves using low-elasticity bandages to apply moderate pressure in multiple layers from distal to proximal at the treatment site.

[0003] Chinese utility model CN217339111U describes a pressure-adjustable elastic strap. It features a strap pressure adjustment structure that works by pulling the strap through the housing to reduce the internal space of the strap, thereby increasing the pressure. Then, by rotating the threaded rod, the connecting plate moves upward, causing the limiting block to insert into the anti-slip groove on the strap to fix its position.

[0004] However, in existing devices, the strap is inside the housing, and when aligning the anti-slip groove with the limiting block, multiple fine adjustments are required to insert the limiting block into the anti-slip groove because the internal situation cannot be observed, which is inconvenient. Therefore, a modern pressure detection device with more convenient adjustment was designed to address the above-mentioned problems. Utility Model Content

[0031] Lymphedema refers to the accumulation of soft tissue fluid on the skin surface due to obstructed lymphatic drainage in certain parts of the body, resulting in subcutaneous fibrous connective tissue hyperplasia and fat hardening after repeated infections. Currently, the most widely used and effective treatment internationally is comprehensive lymphedema treatment (CDT), also known as multi-layer low-elasticity elastic bandage ligation. Multi-layer low-elasticity elastic bandage ligation involves using low-elasticity bandages to apply moderate pressure in multiple layers from distal to proximal at the treatment site.

[0032] In related technologies, the pressure is increased by pulling the strap through the housing to reduce the internal space of the strap, and then rotating the threaded rod to move the connecting plate upward, causing the limiting block to insert into the anti-slip groove on the strap to fix the position of the strap. However, in the existing device, the strap is inside the housing, and when aligning the anti-slip groove with the limiting block, multiple fine adjustments are required to insert the limiting block into the anti-slip groove because the internal situation cannot be observed, which is inconvenient.

[0033] To address some of the problems in related technologies, this application provides a strap pressure detection device. When needed, the strap 12 can be placed on the body, and then the knob 25 can be pulled upwards to disengage the bottom end of the insertion rod 27 from the positioning hole 26. Then, the knob 25 can be rotated, and the rectangular rod 24 can restrict the rotation, causing the upright rod 22 to rotate as well. As the upright rod 22 rotates, it will drive the dial wheel 23 to rotate together. The dial block on the dial wheel 23 will be inserted into the adjustment hole 21. During the rotation, it will push the strap 12 to slide inside the housing 11, thereby reducing the cavity inside the strap 12 and achieving the purpose of wrapping. Then, the knob 25 can be pressed downwards to insert the rectangular rod 24 into the upright rod 22, and the insertion rod 27 can be inserted into the positioning hole 26 to restrict the rotation of the knob 25. At this time, the pressure of the strap 12 can be detected by the pressure sensor 13, and the detected data can be transmitted to the data terminal for viewing.

[0034] This application is described below with reference to the accompanying drawings and specific embodiments:

[0035] Combination Figures 1-4This application provides a strap pressure detection device, comprising: a housing 11 with a strap 12 disposed on its outer side wall, one end of the strap 12 penetrating the housing 11; a pressure sensor 13 disposed on the outer side wall of the housing 11; and a rotating assembly 2 disposed inside the housing 11, the rotating assembly 2 comprising: an adjustment hole 21 opened on the outer side wall of the strap 12; a vertical rod 22 with one end inserted into the interior of the housing 11 and rotatably connected to the housing 11; a dial 23 disposed on the outer side wall of the vertical rod 22; a rectangular rod 24 with its bottom end inserted into the interior of the vertical rod 22; a rotating knob 25 disposed on the top of the rectangular rod 24; a positioning hole 26 opened on the top of the housing 11; and an insertion rod 27 disposed on the bottom of the rotating knob 25 and inserted into the positioning hole 26.

[0036] Specifically, the bandage 12 is a wrap-around bandage structure, and the pressure sensor 13 is a MEMS resistive pressure sensor. The pressure sensor 13 is a device that converts pressure signals into usable output electrical signals. This conversion is achieved jointly by a pressure-sensitive element and a signal processing unit. The working principle of the pressure sensor mainly includes the following steps:

[0037] Sensing element: The core of a pressure sensor is the sensing element, which converts pressure signals into electrical signals. Common sensing elements include piezoresistive, capacitive, piezoelectric, and electromagnetic types. Among them, the piezoresistive sensor is the most widely used.

[0038] Pressure transmission: When pressure is applied to the sensor, the sensor's sensitive element will be subjected to external force, resulting in corresponding deformation or displacement.

[0039] Signal conversion: The deformation or displacement generated by the sensitive element is converted into an electrical signal through a certain mechanical structure. For example, in a piezoresistive sensor, a change in pressure causes a change in the resistance value inside the sensor, which in turn generates an electrical signal.

[0040] Signal processing: The electrical signal is amplified and filtered by the signal processing circuit inside the sensor to improve the stability and accuracy of the signal.

[0041] Output signal: After signal processing, the pressure sensor will generate an electrical signal related to the input pressure as the output, which can be presented in the form of an analog signal or a digital signal.

[0042] In use, the strap 12 can be placed on the body, and then the knob 25 can be pulled upward to disengage the bottom end of the insertion rod 27 from the positioning hole 26. Then, the knob 25 can be rotated. While rotating, the rectangular rod 24 can restrict the rotation, so that the upright rod 22 can rotate with it. When the upright rod 22 rotates, it will drive the dial 23 to rotate together. The dial block on the dial 23 will be inserted into the adjustment hole 21. During the rotation, it will push the strap 12 to slide inside the housing 11, thereby reducing the cavity inside the strap 12 and achieving the purpose of wrapping. Then, the knob 25 can be pressed downward to insert the rectangular rod 24 into the upright rod 22, while the insertion rod 27 is inserted into the positioning hole 26 to restrict the rotation of the knob 25. At this time, the pressure sensor 13 can be used to detect the pressure of the strap 12 and transmit the detected data to the data terminal for viewing.

[0043] In some embodiments, the adjustment hole 21 and the dial 23 are symmetrically arranged in two sets.

[0044] When in use, the design includes two sets of adjustment holes 21 and a dial 23, which can better push the strap 12 through the inside of the housing 11 when rotating.

[0045] In some embodiments, the rotating assembly 2 further includes a baffle 28 disposed at the bottom of the rectangular rod 24.

[0046] The design of the baffle 28 during use can prevent the rectangular rod 24 from detaching from the upright rod 22 when it is raised or lowered.

[0047] In some embodiments, the rotating assembly 2 further includes a spring 29 sleeved on the outside of the rectangular rod 24, with its bottom end connected to the baffle 28.

[0048] When in use, the design of the spring 29 can push the baffle 28 to move downward, thereby pulling the rectangular rod 24 back into the interior of the upright 22, so that the knob 25 moves downward and pushes the insert rod 27 into the interior of the positioning hole 26, making it difficult to detach.

[0049] In some embodiments, the bottom end of each insertion rod 27 is provided with a cone 31.

[0050] When in use, the cone 31 is designed with a pointed bottom, making it easier to move downwards and insert into the positioning hole 26.

[0051] In some embodiments, the inner wall of the positioning hole 26 is fitted to the outer wall of the insertion rod 27.

[0052] The design of the outer wall of the insertion rod 27 and the inner wall of the positioning hole 26 fit together during use, which makes the knob 25 more stable and less prone to shaking after it is fixed.

[0053] In some embodiments, the outer side wall of the knob 25 is provided with a plurality of arc-shaped grooves 32.

[0054] The arc groove 32 is designed to increase friction when rotating the knob 25, thus preventing slippage during rotation.

[0055] In some embodiments, the outer side wall of the housing 11 is symmetrically provided with protruding plates 33, the protruding plates 33 are penetrated by rods 34, and the rods 34 are rotatably connected to the protruding plates 33.

[0056] When in use, the strap 12 will come into contact with the rod 34 when it passes through the housing 11. During the process of passing through, the rod 34 will rotate, thereby reducing the friction between the housing 11 and the strap 12.
