Description

Technical Field

[0001] The invention relates to the field of medical care and monitoring technology, and in particular to a wearable measuring device for measuring lymphedema volume. Background Art

[0002] Lymphedema is a common symptom that mainly affects the upper arms and lower legs of patients, causing local tissue fluid accumulation, swelling and discomfort. This condition not only affects the quality of daily life of patients, but may also indicate potential lymphatic system dysfunction or other health problems. Therefore, effective management and monitoring of lymphedema is particularly important. At present, the treatment of lymphedema mainly relies on physical compression, that is, by wearing devices such as pressure sleeves or elastic stockings, tightly wrapping the edema area to reduce fluid exudation and promote lymphatic return, thereby slowing down the further development of edema. In the medical work of lymphedema, regular monitoring and measurement of the edema area of ​​the patient is the key to assessing the condition, formulating and adjusting the treatment plan. The traditional measurement method is mainly to use a soft ruler to measure the arm circumference to roughly judge the degree of edema. However, this method has obvious limitations: first, the use of a soft ruler for measurement requires frequent operation, which not only increases the workload of medical staff, but also brings additional burden to patients; at the same time, the soft ruler cannot be worn continuously, making it difficult to achieve real-time measurement of the edema area, and it is not convenient to monitor the edema in time. Secondly, the arm circumference needs to be measured multiple times using a soft ruler during the treatment process. There is a large deviation in the measurement position each time, and medical staff are required to record and calculate based on the measurement data, which not only increases the workload but also makes it difficult to ensure data accuracy.

[0003] In summary, the existing lymphedema monitoring and measurement methods have many shortcomings, and there is an urgent need for a wearable monitoring and measurement, more convenient and accurate response method to better meet the clinical needs of lymphedema. Summary of the invention

[0004] The purpose of the present invention is to address the problems existing in the above-mentioned background technology and to propose a wearable measurement device with lymphedema volume measurement, which can be worn on the patient's arm through a sleeve structure to tightly wrap the lymphedema area. At the same time, it is equipped with a convenient and easy-to-operate measurement mechanism, which can measure the arm circumference data in real time and quickly, so as to monitor and obtain the specific condition of edema.

[0005] In order to achieve the above-mentioned object of the invention, the present invention adopts the following technical solutions: A wearable measurement device with lymphedema volume measurement, comprising an elastic sleeve and a measurement mechanism, wherein the elastic sleeve comprises a sleeve body and a front cuff and a rear cuff located at two ends, and a fixing plate is provided on the outer surface of the sleeve body, and the fixing plate is arranged along the axial direction of the sleeve body; the measurement mechanism comprises a plurality of arm circumference measurement parts, and the arm circumference measurement parts comprise a measuring belt that can surround the sleeve body for more than one circle, the measuring belt is made of non-elastic material, and the tail end of the measuring belt is fixedly connected to the fixing plate; the plurality of arm circumference measurement parts are equidistantly distributed along the axial direction of the sleeve body to measure the arm circumference of the arm in sections, and the approximate value of the volume of the edema part of the arm is calculated with the help of the arm circumference data.

[0006] Preferably, the measuring tape is provided with scale lines for measuring length; the fixed plate is provided with a pointer identification portion corresponding to each measuring tape; the measuring tape is tightened around the arm and abuts against the pointer identification portion, at which time the scale value pointed to by the pointer identification portion is the arm circumference.

[0007] Preferably, the fixing plate is also provided with a recording mechanism for recording the data of each arm circumference measurement part, and the recording mechanism includes a writing board or an electronic display with the function of storing and displaying data.

[0008] Preferably, the sleeve body is provided with a plurality of groups of limiting structures for the measuring belt to pass through, and the plurality of groups of limiting structures are arranged one-to-one corresponding to each arm circumference measuring part, and the limiting structure includes a plurality of sleeve openings spaced around the sleeve body, and the measuring belt surrounds the sleeve body and passes through each sleeve opening in turn, and the measuring belt and the sleeve opening are arranged to be relatively slidable.

[0009] Compared with the prior art, the wearable measurement device with lymphedema volume measurement using this solution has the following beneficial effects: 1. The elastic cuff can be worn on the patient's arm to tighten and wrap the lymphedema area, which has a certain therapeutic effect; at the same time, the measuring mechanism matched with the elastic cuff can realize real-time and convenient measurement operation, and can conveniently measure the arm circumference data of each time period. Medical staff can measure and obtain data whenever needed, which reduces the workload and can alleviate the patient's resistance and discomfort.

[0010] Second, through multiple arm circumference measurement parts equidistantly distributed along the axial direction of the sleeve body, the wearable measurement device can calculate the arm volume of a section. Since the arm (especially the edema area) is generally an irregular cylinder, by calculating the volume in multiple sections and then superimposing them, a more accurate edema volume value can be obtained, providing a more accurate quantitative indicator for the monitoring and treatment of lymphedema.

[0011] 3. The scale lines on the measuring tape are combined with the pointer mark on the fixed plate, making the measurement process intuitive and easy to operate. The user only needs to wrap the measuring tape around the arm and tighten it until it is close to the pointer mark to directly read the scale value to obtain the arm circumference data, which greatly simplifies the measurement steps and improves the measurement accuracy.

[0012] Fourth, the recording mechanism set on the fixed board, whether it is a writing board or an electronic display with the function of storing and displaying data, provides users with a convenient way to record data. This not only makes it convenient for users to view historical and current measurement data at any time, but also facilitates doctors to evaluate the progress of edema.

[0013] 5. The limiting structure provides a stable threading path for the measuring belt, and has a limiting storage effect on the measuring belt, which can reduce the length of the measuring belt's free movement outside, avoid damage to the measuring belt or hinder the patient's movement; at the same time, it can avoid lateral deviation of the measuring belt. The measuring belt and the cuff can only slide relative to each other in the direction of the cuff's main body circumference, which can measure the arm circumference more accurately, further improving the stability and accuracy of the measurement.

[0014] In addition to the above technical solutions, the present invention also discloses the following technical solution, which is consistent with the measurement idea of ​​the above solution, but adopts intelligent and automated technology to further simplify the measurement steps. The specific description of the solution is as follows: The measuring belt is provided with a grating sheet; the fixed plate is provided with grating displacement sensors of the same number as the arm circumference measuring parts, each arm circumference measuring part is provided with a corresponding grating displacement sensor, and multiple grating displacement sensors are connected to each other by signals, the measuring belt passes through the grating displacement sensor, and the grating displacement sensor senses the grating sheet to obtain displacement data and then calculates the arm circumference data; a data processing host is also configured, and all grating displacement sensors jointly establish data connection with the data processing host, and the data processing host is configured with a display device or connected to a computer or connected to an intelligent terminal device via a wireless network, so as to perform volume superposition calculation on multiple arm circumference measurement parts to obtain an approximate value of the volume of the arm edema part.

[0015] Preferably, the grating displacement sensor is provided with a display screen for displaying current arm circumference data.

[0016] Preferably, the sleeve body is provided with a plurality of groups of limiting structures for the measuring belt to pass through, and the plurality of groups of limiting structures are arranged one-to-one corresponding to each arm circumference measuring part, and the limiting structure includes a plurality of sleeve openings spaced around the sleeve body, and the measuring belt surrounds the sleeve body and passes through each sleeve opening in turn, and the measuring belt and the sleeve opening are arranged to be relatively slidable.

[0017] Preferably, the grating displacement sensor is provided with an entry and an exit, the head end of the measuring tape enters through the entry and exits through the exit, and both the entry and the exit are provided with a clamping structure for limiting the free sliding of the measuring tape.

[0018] Preferably, the clamping structure includes an upper elastic rubber pad and a lower elastic rubber pad, the upper elastic rubber pad is arranged on the upper side of the insertion port and the insertion port, and the lower elastic rubber pad is arranged on the lower side of the insertion port and the insertion port, and the upper elastic rubber pad and the lower elastic rubber pad jointly clamp the measuring belt.

[0019] Compared with the prior art, the wearable measurement device with lymphedema volume measurement using this solution has the following beneficial effects: 1. By measuring the position and displacement of the belt in the grating displacement sensor, accurate arm circumference data can be automatically obtained without the need for manual reading by medical staff, which not only reduces the workload but also has better data accuracy; each grating displacement sensor measures at each arm circumference measurement part and displays the data on the corresponding display screen, which can allow medical staff to more intuitively know the arm circumference of each area of ​​the arm, which is conducive to quickly and accurately judging the patient's edema condition.

[0020] 2. By collecting and superimposing the data measured by each grating displacement sensor through the data processing host, the edema volume data can be directly obtained without the need for manual calculation by medical staff, thus reducing the workload and difficulty of work. It has higher accuracy and can intuitively display the current degree of edema, the amount of edema increase, the speed of swelling, etc., which is convenient for medical monitoring and timely medical measures.

[0021] 3. The clamping structure of the grating displacement sensor can clamp and restrict the measuring tape, keep the measuring tape flat, and limit the free movement of the measuring tape.

DETAILED DESCRIPTION

[0029] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation mode, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

The elastic sleeve comprises a sleeve body 1 and a front cuff 2 and a rear cuff 3 located at both ends. The sleeve body 1 is made of elastic breathable fabric and can be tightened and wrapped around the patient's arm. A fixing plate 10 is provided on the outer surface of the sleeve body 1. The fixing plate 10 is a long strip-shaped plate structure adapted to the curvature of the arm. The fixing plate 10 is arranged along the axial direction of the sleeve body 1.

The measuring belt 40 is provided with a scale line 400 for measuring the length, and the sleeve body 1 is provided with a plurality of groups of limiting structures for the measuring belt 40 to pass through. The plurality of groups of limiting structures are arranged one by one corresponding to each arm circumference measuring part 4, and the limiting structure includes a plurality of sleeve openings 11 that are spaced around the sleeve body 1, and the measuring belt 40 surrounds the sleeve body 1 and passes through each sleeve opening 11 in sequence, and the measuring belt 40 and the sleeve opening 11 are arranged to be relatively slidable, and the measuring belt 40 and the sleeve opening 11 only slide relative to each other in the circumference direction of the sleeve body 1. The fixed plate 10 is provided with a pointer identification part 41 corresponding to each measuring belt 40. The measuring belt 40 is tightened around the arm and abuts against the pointer identification part 41. At this time, the scale value pointed to by the pointer identification part 41 is the arm circumference. The fixed plate 10 is also provided with a recording mechanism for recording the data of each arm circumference measuring part 4. The recording mechanism is specifically a writing board 42. Each arm circumference measuring part 4 is provided with a writing board 42. The writing board 42 is used by medical staff to write the current and historical arm circumference data by hand.

[0032] By using multiple arm circumference measuring parts 4 equidistantly distributed along the axial direction of the sleeve body 1, the arm circumference of the edematous part of the arm can be measured in sections, and the volume value of each section can be calculated. Since the arm (especially the edematous part) is generally an irregular cylinder, the approximate value of the volume of the edematous part of the arm can be obtained by calculating the volume in multiple sections and then superimposing them; by comparing with the historical record data, information such as how much the edema has increased and the speed of increase can be obtained.

In this solution, the measuring belt 40 does not have a scale line 400, and the pointer identification part 41 and the writing board 42 are no longer provided. The specific description of this solution is as follows: The measuring belt 40 is provided with a grating sheet 401, which is made of flexible PVC or TPU material, and the grating sheet 401 is closely attached to and flush with the surface of the measuring belt 40.

[0034] Each grating displacement sensor 5 is equipped with a display screen 50. When the measuring belt 40 moves through the grating displacement sensor 5, the grating displacement sensor 5 senses the grating sheet 401 to obtain displacement data, and then automatically calculates the arm circumference data and displays it on the display screen 50. The display screen 50 can also display historical measurement data.

[0035] This solution is also equipped with a data processing host 6, and all grating displacement sensors 5 establish data connection with the data processing host 6. The data processing host 6 collects and calculates the data of all grating displacement sensors 5 to realize volume superposition calculation of multiple arm circumference measurement parts 4 to obtain the approximate value of the volume of the arm edema part. The data processing host 6 is equipped with a display device or connected to a computer or connected to an intelligent terminal device through a wireless network, which helps medical staff to intuitively know the patient's arm edema status, facilitate medical monitoring and timely medical measures.
