Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical equipment, in particular to a device for measuring the circumference of an edematous arm. Background Art
[0002] Upper limb lymphedema is a common adverse reaction after cancer surgery and localized chemoradiotherapy. Lymphatic fluid accumulation in the affected limb causes swelling. Severe upper limb swelling can reach 2-3 times the size of a normal arm, necessitating fixed-point arm circumference measurements and recording of treatment data. Currently, arm circumference measurements are typically performed by the patient holding their arm horizontally. Medical staff then use a drafting ruler to measure fixed points, and then use a soft tape measure to measure the arm circumference. This is inconvenient, and the patient's arm exerts force, which can easily lead to measurement errors and affect actual accuracy. Utility Model Content

[0034] The following describes the implementation of the present invention through specific embodiments. People familiar with this technology can easily understand other advantages and effects of the present invention from the contents disclosed in this specification.
[0035] See also Figures 1 to 6The edema arm circumference measuring device provided by the embodiment of the present invention includes: an operating table 1, an arm bracket 2 is fixedly mounted on the operating table 1, and a gap is provided between the arm bracket 2 and the operating table 1 for the size strip of the soft tape measure 3 to pass through; a slide groove 11 is provided on one side of the arm bracket 2 on the operating table 1, and the soft tape measure 3 is slidably connected to the slide groove on the operating table 1 through a slider 31; a slide rail device 5 is provided on the other side of the arm bracket 2 on the operating table 1, and the slide rail device 5 of this embodiment includes a slide rail and a box slidably connected to the slide rail, and the box is equipped with a laser device 4 for positioning the arm. In order to facilitate the selection of the corresponding distance during positioning, a scale is also provided on the slide rail device 9, and there is no need to place a drawing ruler on the arm. When in use, the patient only needs to place the arm to be measured flat on the arm bracket, without having to lift the arm by himself, which effectively avoids the arm from being in a state of exertion. At the same time, the laser device is moved by the slide rail, and the laser device's rays are used to accurately locate the position of the arm to be measured. Generally, the palm, wrist, and 6 / 12 / 18 / 24 / 30 / 36 cm above the wrist are selected for positioning. Then, according to the position located by the laser ray, a soft tape measure is used to wrap around the arm for measurement. The laser positioning is accurate, effectively avoids errors, and is easy to operate.
[0036] In order to facilitate the use of the operating table, the bottom surface of the operating table 1 is also connected to a tripod 6, and a pulley is provided on the tripod 6 to facilitate medical staff to move the placement position according to the needs of operation.
[0037] In order to allow patients to better adapt to the arm placement position and make the arm placement more relaxed, an angle adjustment device 7 for adjusting the inclination of the operating table is also provided between the footrest 6 and the operating table 1. The angle adjustment device 7 includes an arc-shaped mounting seat 71 and an arc-shaped adjustment block 72. The handle 73 can unlock the adjustment block and make the adjustment block slide along the arc of the mounting seat; at the same time, in order to make the height of the operating table adjustable, a gas spring 8 is also provided between the angle adjustment device 7 and the footrest 6. The gas spring lifting and lowering adjustment is a traditional well-known technology and a commonly used structure for office chairs. The relevant structure will not be described in detail here.
[0038] To better position the arm, the laser device 4 is also equipped with a lifting device 9, which includes: a box 91 slidably connected to the slide rail device 5, a gear shaft 92 disposed inside the box 91, an adjustment rocker arm 93 rotatably mounted on the outside of the box 91 and fixedly connected to the gear shaft 92, and a mounting base 94 connected to the box 91 for lifting. The bottom of the mounting base 94 is provided with a rack 95 that meshes with the gear shaft 92. When it is necessary to position arms of different thicknesses, rotating the adjustment rocker arm rotates the gear shaft, thereby driving the rack to raise or lower the mounting base, so that the laser beam is placed exactly on the surface of the arm, improving measurement accuracy.
[0039] In order to make the soft tape measure fit the arm better when measuring the arm and improve the accuracy, the outer edge of the arm bracket 2 along the length direction is made of flexible material. This embodiment uses soft rubber. When the soft tape measure is used to measure the arm, the soft rubber can deform according to the shape of the arm, fit the arm better and increase the accuracy.
[0040] To facilitate measurement, the tape measure 3 is automatically retractable. By pulling the measuring strip 32 around your arm and snapping the clip 33 into the tape measure's slot 34, and pressing the central button 35, the strip automatically retracts, fitting snugly around your arm for easy use. Automatically retractable measuring strips are a well-known technology, commonly used for measuring waist and chest circumferences, and their structure will not be described in detail here.
[0041] It can better limit the placement of the arm and prevent the arm from moving back and forth and affecting the measurement. On the operating table 1, a stopper 10 is also provided on one side of the short side of the bracket 2. The stopper is used to limit the placement position of the palm when the arm is placed. The stopper corresponds to the starting scale position on the slide rail device 9.
[0042] The utility model provides an edematous arm circumference measuring device, which enables the patient to place the arm to be measured flat on the arm bracket without having to lift the arm himself, thus avoiding the arm being in a state of exertion. At the same time, the measurement point of the arm is accurately located by a laser device, and the platform angle is adjustable, allowing the patient's arm to be placed more relaxed. The measuring device can be flexibly moved and placed by the tripod, which has the advantages of convenient operation.
[0043] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by one of ordinary skill in the art without departing from the spirit and technical principles disclosed in the present invention are intended to be covered by the claims of the present invention.
