Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an electronic pressure ulcer measuring ruler. Background Technology

[0002] Pressure ulcers, also known as bedsores or pressure sores, occur in patients who are bedridden or have limited mobility. Prolonged pressure on the body tissues hinders blood circulation in the skin and subcutaneous tissues. Friction between the patient's body and the bed sheet during movement causes skin damage, and shearing forces generated between the body and the bed surface can damage blood vessels in local tissues, further impairing blood circulation and leading to pressure ulcers. In addition, local moisture, irritation from excrement, reduced subcutaneous fat, and muscle atrophy all decrease the skin's tolerance to pressure, making it more susceptible to pressure ulcers. Pressure ulcers not only cause physical pain but can also lead to serious complications such as local and systemic infections, affecting the recovery process and increasing the difficulty of treatment.

[0003] Measuring the size, depth, and area of ​​pressure ulcers helps healthcare professionals assess their severity, enabling accurate grading and diagnosis. This allows for more targeted treatment plans and nursing care. Regular measurements during treatment also provide a visual indication of improvement. Currently, healthcare professionals use pressure ulcer rulers, typically composed of two rulers. By placing the ruler close to the ulcer and reading the markings, the length and width can be measured. However, visual readings are prone to error and time-consuming. Measuring ulcer depth requires a sterile swab or probe inserted deep into the wound. The swab or probe is then aligned with the ulcer surface, and the distance from this point to the end of the swab is measured to determine the ulcer depth. This process requires different measuring instruments, reliance on tactile feedback to probe the deepest part of the wound, and manual measurement, all of which can affect the accuracy and efficiency of the measurements. Utility Model Content

[0004] The purpose of this invention is to provide an electronic pressure ulcer measuring ruler, so that medical staff can measure the length, width and depth of pressure ulcers, avoid errors caused by manual reading, and improve measurement efficiency and accuracy.

[0005] To solve the above-mentioned technical problems, this utility model provides an electronic pressure ulcer measuring ruler, including a horizontal main ruler, a vertical auxiliary ruler slidably connected to the horizontal main ruler, a first displacement sensor on the horizontal main ruler, an electrically telescopic rod on the vertical auxiliary ruler, a second displacement sensor on the vertical auxiliary ruler, a pressure sensor installed at the top of the vertical auxiliary ruler away from the horizontal main ruler, a housing installed on the horizontal main ruler, a display screen embedded in the housing, and the display screen, the first displacement sensor, the second displacement sensor, the pressure sensor, and the vertical auxiliary ruler are all electrically connected to a controller.

[0006] It should be noted in the solution that a slide rail is provided on the horizontal main scale, and correspondingly, a slider is provided at the connection between the vertical secondary scale and the horizontal main scale, and the first displacement sensor is installed on the inner side wall of the slide rail.

[0007] In a preferred embodiment, the housing is located at the connection between the horizontal main scale and the vertical secondary scale, the housing is slidably connected to the horizontal main scale, and a friction pad is provided on the contact surface between the housing and the horizontal main scale.

[0008] It is worth noting that the housing is equipped with a zeroing button and a telescopic control button, which are electrically connected to the controller.

[0009] In a preferred embodiment, a flexible support rod is installed at the end of the horizontal main scale away from the sliding direction of the vertical secondary scale, and a miniature camera is fixed at the top of the flexible support rod. The miniature camera is wirelessly connected to the controller.

[0010] In a preferred embodiment, the controller includes a Bluetooth module or a Wi-Fi module, and an indicator light is provided on the housing, which is electrically connected to the controller.

[0011] In a preferred embodiment, a vibration motor is installed at the gripping end of the horizontal main ruler, and the vibration motor is electrically connected to the controller.

[0012] As a preferred embodiment, the feature is that both the horizontal main scale and the vertical secondary scale are provided with scale lines.

[0013] In a preferred embodiment, the telescopic end of the vertical scale is fitted with a medical flexible silicone sleeve, and the medical flexible silicone sleeve is provided with scale lines.

[0014] Compared with the prior art, the electronic pressure ulcer measuring ruler provided by this utility model has at least the following beneficial effects:

[0015] The vertical auxiliary ruler can slide along the horizontal main ruler. A first displacement sensor is installed on the horizontal main ruler. Pushing the vertical auxiliary ruler along the horizontal main ruler from one end of the longest direction of the pressure ulcer to the other, the first displacement sensor measures the sliding displacement of the vertical auxiliary ruler to obtain the length of the pressure ulcer. The vertical auxiliary ruler is an electrically telescopic rod, equipped with a second displacement sensor. Controlling the extension of the vertical auxiliary ruler from one end of the pressure ulcer width to the other, the second displacement sensor measures the extension amount to obtain the width of the pressure ulcer. A pressure sensor is installed at the top of the vertical auxiliary ruler, away from the horizontal main ruler. When measuring the pressure ulcer depth, controlling the vertical auxiliary ruler to extend from the surface of the pressure ulcer towards the bottom of the pressure ulcer, the vertical auxiliary ruler stops extending when the pressure sensor detects that the end of the vertical auxiliary ruler has reached the deepest point of the pressure ulcer. This design avoids secondary damage to the wound. The elongation measured by the second displacement sensor is the pressure ulcer depth. The vertical auxiliary ruler, in conjunction with the horizontal main ruler, allows medical staff to easily measure the length, width, and depth of the pressure ulcer without changing the measuring instruments. The vertical auxiliary ruler and pressure sensor help medical staff accurately and conveniently detect the pressure ulcer depth. The horizontal main ruler's housing is equipped with a display screen. The display screen, the first displacement sensor, the second displacement sensor, the pressure sensor, and the vertical auxiliary ruler are all electrically connected to the controller. Measurement data can be transmitted to the display screen through the controller, allowing medical staff to see the measurement results directly on the screen. This improves efficiency while avoiding operational errors caused by manual reading, ensuring the accuracy of the measurement results. Attached Figure Description

[0022] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0023] The core of this invention is to provide an electronic pressure ulcer measuring ruler, which enables medical staff to measure the length, width, and depth of pressure ulcers, avoiding errors caused by manual readings and improving measurement efficiency and accuracy.

Figure 2 This is a schematic diagram of the structure of an electronic pressure ulcer measuring ruler provided by this utility model. Figure 3 This is a schematic diagram of the installation structure of the horizontal main scale and the vertical auxiliary scale provided by this utility model.

[0025] Example 1

[0026] An electronic pressure ulcer measuring ruler includes a horizontal main scale 1 and a vertical secondary scale 2, wherein the vertical secondary scale 2 is slidably mounted on the horizontal main scale 1. (See reference...) Figure 3 and Figure 4In some feasible implementations, a slide rail 8 is provided on the horizontal main scale 1, and correspondingly, a slider 9 is provided on the vertical secondary scale 2. The slider 9 is located at the connection between the vertical secondary scale 2 and the horizontal main scale 1. When medical staff measure pressure ulcers, they hold the end of the horizontal main scale 1 away from the sliding direction of the vertical secondary scale 2, bring the horizontal main scale 1 close to the position aligned with the longest diameter of the pressure ulcer, so that the vertical secondary scale 2 is at one end of the longest diameter of the pressure ulcer, and then push the vertical secondary scale 2. The slider 9 of the vertical secondary scale 2 slides on the slide rail 8, realizing that the vertical secondary scale 2 slides from one end of the longest diameter of the pressure ulcer to the other end along the horizontal main scale 1. A first displacement sensor 3 is provided on the horizontal main scale 1. The sliding distance of the vertical secondary scale 2 is measured by the first displacement sensor 3 to obtain the length of the pressure ulcer. It is worth noting that the first displacement sensor 3 is installed... The inner wall of the slide rail 8 facilitates accurate measurement of the displacement of the slider 9. The first displacement sensor 3 can be a photoelectric displacement sensor, a magnetic grating displacement sensor, a capacitive displacement sensor, etc. Specifically, if a photoelectric displacement sensor is used, an encoding strip can be fixed on the side of the slider 9 close to the photoelectric displacement sensor. As the slider 9 moves, the position of the pattern on the encoding strip relative to the photoelectric displacement sensor changes. The photoelectric displacement sensor reads the sliding displacement by detecting the change in the pattern of the encoding strip. Alternatively, a reflective strip can be fixed on the side wall of the slider 9. The photoelectric displacement sensor measures the displacement of the slider 9 by detecting the change in the reflected light from the reflective strip. The above structure should not be construed as a limitation on the first displacement sensor 3. It should be further noted that the installation of the first displacement sensor 3 should not affect the sliding of the slider 9 on the slide rail 8.

[0027] See Figure 1The vertical auxiliary ruler 2 is an electrically telescopic rod, electrically connected to the controller. In some feasible implementations, the interior of the horizontal main ruler 1 is hollow to facilitate wiring during actual installation. The vertical auxiliary ruler 2 is controlled to extend from one end of the pressure ulcer width to the other. The vertical auxiliary ruler 2 is equipped with a second displacement sensor 4. By detecting the extension of the vertical auxiliary ruler 2 by the second displacement sensor 4, the width of the pressure ulcer can be measured. The second displacement sensor 4 can be a capacitive displacement sensor, a photoelectric displacement sensor, a magnetic grating displacement sensor, etc. Similarly, the vertical auxiliary ruler 2 can also be used to measure the depth of the pressure ulcer. The vertical auxiliary ruler 2 is controlled to extend from the surface of the pressure ulcer to the depth of the pressure ulcer. Similarly, the extension of the vertical auxiliary ruler 2 measured by the second displacement sensor 4 is the depth of the pressure ulcer. It should be noted that... The second displacement sensor 4 is installed on the support end of the vertical auxiliary ruler 2 and is not affected by the extension and retraction of the vertical auxiliary ruler 2. A pressure sensor 5 is installed at the top of the second vertical auxiliary ruler 2 away from the horizontal main ruler 1. The pressure sensor 5 is electrically connected to the controller. During depth measurement, after the pressure sensor 5 senses that the vertical auxiliary ruler 2 has contacted the bottom of the pressure ulcer, the vertical auxiliary ruler 2 stops extending to prevent excessive pressure on the patient's wound during depth measurement and secondary injury to the patient. It should be noted that in some feasible implementations, a cable storage groove is opened inside the vertical auxiliary ruler 2, which is not shown in the attached figure, to accommodate the flexible cable of the pressure sensor 5 to avoid affecting the extension and retraction of the vertical auxiliary ruler 2. Wireless transmission can also be used to avoid the cable affecting the extension and retraction of the vertical auxiliary ruler 2.

[0028] See Figure 2 and Figure 1 A housing 6 is mounted on the horizontal main scale 1, and a display screen is embedded in the housing 6. The display screen, the first displacement sensor 3, and the second displacement sensor 4 are all electrically connected to the controller. The data measured by the first displacement sensor 3 and the second displacement sensor 4 are transmitted through the controller and displayed on the display screen for easy reading by medical personnel. Preferably, the display screen can be an e-ink screen, which can maintain low power consumption while displaying for a long time. In some feasible implementations, the housing 6 is located at the connection between the horizontal main scale 1 and the vertical secondary scale 2, and the housing 6 is slidably connected to the horizontal main scale 1. When medical personnel push the vertical secondary scale 2 to slide, the housing 6 slides along the horizontal main scale 1, which not only facilitates reading during measurement but also allows the movement of the vertical secondary scale 2 to be controlled by pinching the housing 6, improving the convenience and stability of the movement of the vertical secondary scale 2. Preferably, the contact surface between the housing 6 and the horizontal main scale 1 is provided with a friction plate (not shown in the figure). The friction plate can increase the stability of the vertical secondary scale 2 when it slides to the designated position, preventing the vertical secondary scale 2 from shaking or deviating. It is worth noting that both the horizontal main scale 1 and the vertical auxiliary scale 2 have gripping ends. Specifically, the connection between the horizontal main scale 1 and the vertical auxiliary scale 2 forms a cross shape. The short handle end of the cross makes it easy for medical staff to hold the measuring scale stably. The power module can be installed at the gripping end.

[0029] See Figure 2 Furthermore, it is worth noting that the housing 6 is equipped with a zeroing button 10 and a telescopic control button 11. These buttons are electrically connected to the controller. The zeroing button 10 allows the measurement data to be reset before measurement, while the telescopic control button 11 facilitates the extension of the vertical scale 2 for measurement by medical personnel. Medical personnel can use both the zeroing button 10 and the telescopic control button 11 during measurement for flexible and convenient operation of the electronic pressure ulcer measuring ruler. Even if operational errors occur, adjustments can be made promptly. The learning curve is low, and the system is highly flexible, adaptable to various complex usage scenarios for medical personnel.

[0030] Example 2

[0031] Based on Example 1, since pressure ulcer assessment requires comprehensive observation of the skin and tissue condition, currently, medical staff also use mobile phones to take photos to record the patient's pressure ulcer condition. However, the use of mobile phones increases the risk of infection and is inconvenient for management. To address this, a flexible support rod 12 is installed at the end of the horizontal main ruler 1 away from the sliding direction of the vertical secondary ruler 2, and a miniature camera 13 is fixed to the top of the flexible support rod 12. (See Example 1) Figure 2 The miniature camera 13 is wirelessly connected to the controller. While measuring the pressure ulcer, the miniature camera 13 automatically captures images of the ulcer. Before measurement, medical staff can adjust the position of the miniature camera 13 using the flexible support rod 12 to ensure accurate image capture. The automated control of the miniature camera 13 can be achieved through existing program settings. However, the control program is not within the scope of this invention and will not be described further here.

[0032] Preferably, the controller includes a Bluetooth module or a Wi-Fi module, allowing measurement data and captured photos to be directly transmitted to hospital computers or other devices via Bluetooth or Wi-Fi. This efficiently and synchronously records and stores data, facilitating subsequent review and comparison of pressure ulcer changes by medical staff. (See reference...) Figure 2 An indicator light 14 is provided on the housing 6. The indicator light 14 is electrically connected to the controller. During image capture, measurement, and data transmission, feedback to medical staff can be provided through the color and flashing of the indicator light 14. Preferably, a vibration motor 15 is installed at the gripping end of the horizontal main scale 1. (See [reference]) Figure 1The vibration motor 15 is electrically connected to the controller. When the pressure sensor 5 detects that the vertical auxiliary ruler 2 has contacted the bottom of the pressure ulcer, the controller stops the extension of the vertical auxiliary ruler 2 and simultaneously controls the vibration motor 15 to vibrate, providing vibration feedback to medical staff to indicate that the vertical auxiliary ruler 2 has reached the bottom of the pressure ulcer, allowing medical staff to be aware of the depth measurement status in a timely manner. It is further worth noting that both the horizontal main ruler 1 and the vertical auxiliary ruler 2 are equipped with graduation lines, retaining physical graduations. This can both assist in verifying the accuracy of the electronic readings and serve as a traditional mechanical backup in case of equipment failure or unavailability. Preferably, since the vertical auxiliary ruler 2 penetrates deep into the pressure ulcer during depth measurement, a medical flexible silicone sleeve 16 is fitted over the telescopic end of the vertical auxiliary ruler 2. (See [reference]). Figure 3 It can act as a physical barrier to prevent direct contact between the vertical scale 2 and the wound. The medical flexible silicone sleeve 16 is soft and causes less irritation to the wound and surrounding tissues, reducing patient discomfort during operation and minimizing friction and pressure from the equipment on the wound edges and surrounding tissues, thus reducing the risk of injury. When measuring pressure ulcers in different patients, medical staff can quickly change the medical flexible silicone sleeve 16 to prevent cross-infection. It can also be reused after subsequent disinfection. Similarly, see [reference needed]. Figure 2 The medical flexible silicone sleeve 16 also has scale lines, preserving the traditional mechanical measurement method for medical staff.

[0033] This invention utilizes a vertical auxiliary ruler 2 to slide along the horizontal main ruler 1 from one end of the longest direction of the pressure ulcer to the other. A first displacement sensor 3 measures the sliding displacement of the vertical auxiliary ruler 2 to obtain the length of the pressure ulcer. The vertical auxiliary ruler 2 is then controlled to extend from one end of the pressure ulcer width to the other, and a second displacement sensor 4 measures the extension to obtain the width of the pressure ulcer. When measuring the depth of the pressure ulcer, the vertical auxiliary ruler 2 is controlled to extend from the surface of the pressure ulcer towards the bottom. When the pressure sensor 5 at the top of the vertical auxiliary ruler 2 senses that the end of the vertical auxiliary ruler 2 has reached the deepest point of the pressure ulcer, the vertical auxiliary ruler 2 stops extending. To avoid secondary damage to the wound, the elongation measured by the second displacement sensor 4 is the pressure ulcer depth. The vertical auxiliary ruler 2, in conjunction with the horizontal main ruler 1, allows medical staff to easily measure the length, width, and depth of the pressure ulcer without changing the measuring instruments. The vertical auxiliary ruler 2 and the pressure sensor 5 help medical staff accurately and conveniently detect the pressure ulcer depth. The measurement data can be transmitted to the display screen through the controller, and medical staff can see the measurement results through the display screen, which improves efficiency and avoids the operational errors caused by manual reading, ensuring the accuracy of the measurement results.
