Description

Technical Field

[0001] The utility model relates to the technical field of upper limb edema measurement, in particular to an upper limb lymphedema measurement device. Background Art

[0002] Upper limb lymphedema is caused by the obstruction of lymphatic fluid return, which leads to swelling of the upper limbs. This may be caused by many reasons, including bad living habits, upper limb trauma, upper limb infection, upper limb lymphedema after breast cancer surgery, and filariasis. Bad living habits, such as staying up late for a long time, overwork, etc., may lead to a decrease in the body's immunity, thereby causing upper limb lymphedema. In addition, the upper limbs are hit by external forces or bacterial infections. Ways to prevent upper limb lymphedema include avoiding carrying heavy objects in the hands or shoulders, avoiding activities that require excessive force on the arm muscles, trying to place the arms above the heart, avoiding direct heat on the arms, and paying attention to skin care to avoid skin injuries;

[0003] An upper limb lymphedema measuring device is a device specifically used to measure and evaluate the lymphedema of the upper limbs. The design and use of this device can help doctors or therapists accurately determine the degree of lymphedema, thereby formulating a more effective treatment plan. Currently, there are many types of upper limb lymphedema measuring devices, among which some devices are based on the displacement volume method or water displacement principle, and evaluate the edema by measuring the volume change of the limb in a specific container. These devices usually include a transparent container that can hold a certain amount of water, and tools for measuring and recording water level changes. These measuring devices have their own advantages and disadvantages. The displacement volume method and water displacement method are relatively simple to operate, but may take a certain amount of time to complete the measurement. The blood loss meter and bioelectrical impedance spectroscopy measurement method are faster and more accurate, but the equipment cost may be higher and the operation may be more complicated.

[0004] After searching, the utility model with the announcement number CN216365032U discloses a device for measuring upper limb lymphedema. Although the utility model patent fixes an adjustable tape measure at each point, it solves the problem of repeated use of the same tape measure, which is prone to measurement errors and saves measurement time;

[0005] First, the utility model is troublesome when connecting the upper limb lymphedema measuring device to the patient's upper limb. Since the connecting groove is small and the soft ruler is difficult to control, it is difficult for the patient to achieve autonomous measurement, and the practicality is low;

[0006] Second, the utility model lacks a fixing component when connected to the patient's upper limb, so the positioning plate is easily displaced during measurement, causing measurement errors;

[0007] Therefore, a device for measuring upper limb lymphedema is proposed. Utility Model Content

[0027] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0028] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0029] like Figure 1-4 As shown, an embodiment of the utility model provides an upper limb lymphedema measuring device: it includes a support frame 1, a support plate 2 is fixedly connected to the outside of the support frame 1, a motor 3 is fixedly connected to one side of the support plate 2, a turntable 4 is fixedly connected to the output end of the motor 3, a support block 1 5 and a support block 2 7 are fixedly connected to the inside of the support frame 1, a long rod 6 is fixedly connected to the outer wall of the support block 1 5, a connecting rod 8 is rotatably connected to the inside of the support block 2 7, a turntable 2 9 is fixedly connected to the outer wall of the connecting rod 8, a belt 10 is installed on the outer walls of the turntable 2 9 and the turntable 1 4, a threaded rod 1 11 is fixedly connected to one end of the connecting rod 8, a threaded rod 2 12 is fixedly connected to the other end of the connecting rod 8, the thread directions of the threaded rod 1 11 and the threaded rod 2 12 are opposite, the outer walls of the threaded rod 1 11 and the threaded rod 2 12 are threadedly connected to a support block 3 13, the support block 3 13 slides on the outer wall of the long rod 6, a clamping block 14 is fixedly connected to one side of the support block 3 13, and an auxiliary wheel 16 is rotatably connected to the clamping block 14.

[0030] In one embodiment, a group of clamps 14 is fixedly connected with a positioning plate 18, a side of the positioning plate 18 close to the groove 15 is fixedly connected with a magnet 19, a side of the positioning plate 18 is fixedly connected with a soft ruler 20, a surface of the soft ruler 20 is provided with a scale 23, an outer wall of the soft ruler 20 is slidably connected with a positioning plate 22, and a side of the positioning plate 22 close to the patient's upper limb is fixedly connected with a magnet 21. Multiple groups of soft rulers 20 are provided, and the multiple groups of soft rulers 20 are evenly distributed. Multiple groups of soft rulers 20 and magnet 21 make the measurement of upper limb edema of patients more detailed.

[0031] In one embodiment, a groove 15 is provided on one side of the clamp 14 close to the patient's upper limb. The groove 15 makes the clamp 14 fit the patient's upper limb more closely. A gasket 17 is fixedly connected to the outer wall of the auxiliary wheel 16, and four auxiliary wheels 16 and gaskets 17 are provided, and the four auxiliary wheels 16 and gaskets 17 are respectively located in two clamps 14. Multiple auxiliary wheels 16 and gaskets 17 make the clamp 14 fit the patient's upper limb during fixation, and at the same time, the comfort level is higher. The shape of the support frame 1 is "U"-shaped, and the "U" shape of the support frame 1 faces the patient. The long rod 6 is parallel to the connecting rod 8, the threaded rod one 11 and the threaded rod two 12 respectively. There are two clamps 14, and the two clamps 14 are fixedly connected to the support block three 13 respectively, and the shape of the two clamps 14 is "C"-shaped. The "C" shape of the clamp 14 reduces a certain counterweight, so that the patient is more comfortable during the measurement process.

[0032] When the utility model is working: the support frame 1 is placed at a suitable position of the patient's upper limb, the motor 3 is started, and the motor 3 drives the turntable 1 4 to rotate. Under the cooperation of the belt 10, the turntable 1 4 rotates and drives the turntable 2 9 to rotate. Since the turntable 2 9 is fixedly connected to the connecting rod 8, the rotation of the turntable 2 9 drives the connecting rod 8 to rotate. Since the two ends of the connecting rod 8 are respectively fixedly connected to the threaded rod 1 11 and the threaded rod 2 12, the rotation of the connecting rod 8 drives the threaded rod 1 11 and the threaded rod 2 12 to rotate. Since the outer walls of the threaded rod 1 11 and the threaded rod 2 12 are threadedly connected with the support block 3 13, the support block 3 13 moves with the rotation of the threaded rod 1 11 and the threaded rod 2 12. Under the cooperation of the long rod 6, the support block 3 13 slides on the outer wall of the long rod 6, and the support Block three 13 moves horizontally on the surface of threaded rod one 11 and threaded rod two 12. Since the thread directions of threaded rod one 11 and threaded rod two 12 are opposite, the two support blocks three 13 threadedly connected to threaded rod one 11 and threaded rod two 12 respectively move toward each other, and the two clamping blocks 14 move toward each other, thereby fixing the patient's upper limb. After fixation, the upper limb lymphedema measuring device is not easy to shift, and the measurement result is more accurate; the patient uses one hand to wrap the positioning plate two 22 around the patient's upper limb until the magnet two 21 fits with the magnet one 19, and pulls the soft tape measure 20 respectively, so that the soft tape measure 20 slides in the positioning plate two 22 until the soft tape measure 20 is close to the surface of the upper limb to be measured, and reads the scale 23 data respectively. The measurement process is convenient and quick, and the patient can complete the test independently.
