Description

Technical Field

[0001] The utility model relates to the technical field of pressure detectors, in particular to a bandage pressure detector which is easy to disassemble. Background Art

[0002] In medicine, bandage compression therapy is a common treatment method that uses pressure devices to produce continuous or intermittent compression or suction on the local body to achieve the goal of alleviating clinical symptoms and promoting wound repair.

[0003] Lower bandage pressure (e.g., 30-40 mmHg) plays an important role in the treatment of common diseases such as varicose veins and edema, while higher bandage pressure (above 200 mmHg) can be used as a tourniquet and for amputation recovery. The specific pressure value should be related to the patient's BMI (body mass index, a method of measuring a person's weight by the ratio of weight to height), limb diameter, and lesion location.

[0004] However, current bandage compression therapy relies heavily on the experience of doctors or nurses, resulting in unstable pressure application and inability to adapt to the varying needs of patients with different affected areas, impacting treatment effectiveness. Therefore, it is necessary to develop a bandage pressure detector to make bandage compression therapy more standardized, accurate, and effective. Utility Model Content

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the problem that the bandage with a ruler in the prior art can roughly estimate the amount of pressure applied, but the error with the actual pressure value is large. In addition to being related to the length of the bandage, the actual pressure applied is also related to the patient's BMI, limb diameter and lesion location (for example, the pressure applied to the lower limbs should be greater than that of the upper limbs), and the ruler on the bandage cannot take these factors into account well, and the actual applied pressure and the ruler value are quite different. Another method is to apply pressure through bandages of different materials (such as foam bandages, high-elasticity bandages, etc.), which can adapt to the different needs of patients to a certain extent, but it is still impossible to clearly determine the exact amount of pressure applied, and thus the problem of being unable to accurately implement pressure therapy.

[0006] To address the above technical problems, the present invention provides a removable bandage pressure detector, comprising: an elastic bandage with a scale for measuring the length of the bandage and thereby quantifying its tightness; a plurality of fixed cloth straps disposed on one side of the bandage; a plurality of pressure sensors secured to the bandage by the fixed cloth straps and configured to detect the applied pressure of the bandage; and a pressure detection plate with a terminal block disposed thereon, the pressure sensors being electrically connected to the terminal block via a wire, the pressure detection plate being configured to display the pressure value detected by the pressure sensors. The removable bandage pressure detector, in combination with the elastic bandage and pressure sensor, can accurately measure the pressure value during bandage pressure therapy, thereby resolving the problem of bandage pressure therapy relying on experience, resulting in inaccurate and unstable applied pressure. This structure allows doctors to determine the applied pressure value based on the patient's specific condition and lesion location, allowing accurate implementation of bandage pressure therapy through the device to optimize the treatment effect. This structure also quantifies the tightness of the bandage through the design of a ruler, making bandage pressure therapy easier. The elastic bandage and pressure sensor are designed to be detachable, which broadens the range of applications of the product.

[0007] In one embodiment of the present invention, the pressure sensor includes a wire, a fixing hook, a base, and a flexible pressure sensor body. One end of the wire is connected to the base, and the other end of the wire is connected to a terminal block. The flexible pressure sensor body is fixedly mounted on the base and is used to detect the pressure applied by an elastic bandage. The fixing hook is mounted on the base and is attached to the surface of the elastic bandage. The flexible pressure sensor body is fixed by a colloid base, which not only fixes the position of the sensor to accurately measure the pressure at a specific location, but also allows the colloid material to effectively transmit pressure, with minimal impact on the measured pressure value. The colloid base also facilitates the installation of a plastic fixing hook, which can stabilize the position of the sensor.

[0008] In one embodiment of the present invention, the cross-section of the elastic bandage is rectangular.

[0009] In one embodiment of the present invention, the ruler is printed on the elastic bandage and is located on the long side of one side of the elastic bandage. The ruler is a plurality of linear scales printed on the elastic bandage that can quantify the tightness of the bandage and thus quantitatively record the amount of pressure applied.

[0010] In one embodiment of the present invention, the plurality of fixing straps are arranged in a rectangular array, and the positions of the fixing straps are adapted to mark the locations of the pressure sensors. The fixing straps are sewn onto the elastic bandage and have two functions: first, they secure the pressure sensors in place, and second, when the bandage is wrapped around the patient's limb, they can locate the pressure sensors, thereby accurately identifying the source of the monitored pressure.

[0011] In an embodiment of the present invention, the fixing hook is made of plastic.

[0012] In one embodiment of the present invention, the base is made of silicone.

[0013] In one embodiment of the present invention, the flexible pressure sensor body is a piezoresistive pressure sensor.

[0014] In one embodiment of the present invention, the flexible pressure sensor body is an FSR400 pressure sensor.

[0015] In one embodiment of the present invention, the unfolded area of the elastic bandage is 7.5 cm*90 cm.

[0016] The above technical solution of the utility model has the following beneficial effects compared with the prior art:

[0017] The easily removable bandage pressure detector described in this utility model combines a traditional bandage with a pressure sensor to accurately and in real time display the pressure applied by the bandage at different locations. This allows the physician to adjust the tightness of the bandage accordingly, and thus precisely adjust the bandage pressure according to the patient's specific condition. The bandage is equipped with a scale that quantitatively records the bandage's state under the current pressure, ensuring that the pressure value remains relatively constant after multiple bandage installations and removals, eliminating the need for multiple testing. The pressure sensor can be easily removed from the bandage, at which point the device can be used as a standard bandage. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0025] Reference Figure 1 、 3 As shown, the bandage pressure detector that is easy to disassemble of the present invention includes: an elastic bandage 1, a ruler 2, a fixing cloth tape 3, a pressure sensor 4, a terminal block 5 and a pressure detection plate 6; the elastic bandage 1, which serves as the basic part of the device, is provided with a ruler 2 on the elastic bandage 1, and the ruler 2 is used to measure the length of the elastic bandage 1 and thus quantify the tightness of the elastic bandage 1; the fixing cloth tape 3 is provided in a plurality of numbers, and the fixing cloth tape 3 is provided on one side of the elastic bandage 1; the pressure sensor 4 is provided in a plurality of numbers, and the pressure sensor 4 is limited on the elastic bandage 1 by the fixing cloth tape 3, and the pressure sensor 4 is used to detect the applied pressure of the elastic bandage 1; the pressure detection plate 6, which is provided with a terminal block 5, and the pressure sensor 4 is electrically connected to the terminal block 5 through a wire, and the pressure detection plate 6 is used to display the pressure value detected by the pressure sensor 4.

[0026] Reference Figure 2 As shown, the pressure sensor 4 includes a wire 7, a fixing hook 8, a base 9 and a flexible pressure sensor body 10, one end of the wire 7 is connected to the base 9, and the other end of the wire 7 is connected to the terminal block 5, the flexible pressure sensor body 10 is fixedly set on the base 9, and the flexible pressure sensor body 10 is used to detect the applied pressure of the elastic bandage 1, the fixing hook 8 is set on the base 9, and the fixing hook 8 is attached to the surface of the elastic bandage 1.

[0027] The wire 7 can be connected to the terminal block 5 to transmit the pressure signal. The material of the fixing hook 8 is plastic, and the fixing hook 8 is combined with the surface structure design of the bandage, which can be attached to the surface of the bandage and is not easy to fall off or shift. It is also short (about 1 cm) and will not affect the pressure monitoring. The material of the base 9 is silicone, and the base 9 is used to fix the flexible pressure sensor body 10. Its surface area is slightly larger, which can stabilize the position of the flexible pressure sensor body 10, and its colloid material will not affect the pressure value to be measured. The flexible pressure sensor body 10 is a typical piezoresistive pressure sensor, such as FSR400. Its resistance decreases as the pressure increases, and it can better reflect the pressure value on the bandage surface.

[0028] In the above structure, the elastic bandage 1 has a rectangular cross-section. Its unfolded area measures 7.5 cm by 90 cm, and serves to apply pressure. The scale 2 is printed on the elastic bandage 1 and located on one long side of the bandage. Using the scale 2, the length of the bandage 1 is measured, thereby gauging its tightness, making pressure adjustment simple and visual.

[0029] In the above structure, the plurality of fixing tapes 3 are arranged in a rectangular array, and the positions of the fixing tapes 3 can mark the positions of the pressure sensors 4 .

[0030] Reference Figure 4 As shown, the pressure detection board 6 in the above structure mainly consists of a pressure detection circuit, an STM32 microcontroller, a Bluetooth module, and a display screen. The pressure detection circuit is a series resistor voltage divider circuit consisting of a fixed resistor R and a flexible pressure sensor connected by a terminal block. The microcontroller calculates the bandage pressure by monitoring the voltage value, displays it directly on the display screen, and uploads it to the host computer (computer) via the Bluetooth module, realizing the bandage pressure monitoring function.

[0031] To prepare the detachable bandage pressure detector of this utility model, it is necessary to select an elastic bandage 1 of appropriate size, sew several fixing cloth strips 3 of 1-2 cm in length evenly on the bandage surface, and mark a scale 2 on one side of the elastic bandage. To prepare the pressure sensor 4, it is necessary to fix the fixing hook 8 and the flexible pressure sensor body 10 on the base 9 and connect them to the pressure detection plate 6 via the wire 7. Then, the elastic bandage 1 and the pressure sensor 4 are combined to complete the device.

[0032] During use, the appropriate fixing tape 3 is selected based on the actual needs of the patient's test site. The pressure sensor 4 is mounted on the elastic bandage 1, ensuring that the fixing hook 8 is securely connected to the elastic bandage 1. The device is then wrapped around the patient's limb to be tested. The current applied pressure is read from the pressure detection plate 6. The tightness of the elastic bandage 1 is then adjusted until the desired pressure is reached. During this process, the relative magnitude of the current pressure can be measured by reading the scale value.

[0033] When the pressure reaches the appropriate value, record the current scale value, then remove the pressure sensor 4. The next time you perform bandage pressure therapy at the same location, you only need to adjust the tightness of the bandage to the current scale value to achieve the ideal treatment effect.

[0034] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
