Description

Limb circumference detection device, limb compliance measurement device and lymphedema treatment device composed of the device

The invention relates to a device for detecting the circumference of a limb. More specifically, it relates to a detection device for continuously measuring the circumference of each position of a limb and capable of measuring the compliance of the limb and treating the treatment of limb edema.

After breast cancer, gynecology or pelvic cancer patients undergo surgical treatment, due to the removal of lymph nodes and subsequent radiotherapy and chemotherapy will cause tissue fibrosis, resulting in obstruction of the lymphatic circulation path. The accumulation of lymph fluid in the tissue causes swelling, which is called lymphedema, especially in the limbs.

Lymphedema is caused by an imbalance in the leakage and recovery of lymph fluid. Therefore, lymphedema usually does not occur immediately after surgery and radiotherapy and chemotherapy, but only gradually after months or even years. Lymphedema can seriously affect the patient's appearance, confidence, and function of daily life.

In view of the good early treatment after lymphedema, the patient needs a convenient device to monitor the circumference of the limb after surgery and radiotherapy and chemotherapy in order to track the occurrence of lymphedema. In addition, recording data on the circumference of the patient's limbs allows medical personnel to adjust the rehabilitation plan according to the patient's condition to better suit the patient.

Furthermore, it has been found from clinical experience that the compliance of the limb represents the pressure inside the limb, and may also be an indicator of the change in the degree of swelling and the therapeutic effect, so it is also necessary to measure. Lymphedema can be relieved by free-hand lymphatic drainage, but free-hand lymphatic drainage needs to be performed by professionals, which is quite labor-intensive and requires implementation in medical institutions. Therefore, it is urgent to develop a device that can achieve the above-mentioned treatment effects.

Please refer to FIG. 1, which is a first schematic diagram of a limb circumference detection device of the present invention. The invention provides a limb circumference detection device, which includes a cable module 1, a first measurement module 2 and a second measurement module 3. The wire drawing module 1 includes a surrounding element, and the surrounding element can be arranged around the limb 100, and the first measuring module 2 and the second measuring module 3 are arranged on the wire drawing module 1. The first measurement module 2 moves along the long axis of the limb 100 and measures the length of the limb 100, and at the same time, the second measurement module 3 simultaneously measures the length of the cable module 1 surrounding the limb 100 , That is, the circumference of the limb 100. The limb 100 may include an upper limb or a lower limb, and in the embodiment of the present invention, the upper limb is taken as an example for description.

In the embodiment shown in FIG. 1, the cable module 1 may include a connecting wire 11, and the surrounding element may be, for example, a bead chain 12 sleeved on the connecting wire 11. The bead chain 12 has a flexible but non-retractable characteristic. The first measurement module 2 may include a roller 21 and a first rotation angle detection unit 22 connected to the roller 21. The first rotation angle detection unit 22 is used to measure the rotation angle of the roller 21. The second measurement module 3 may include a ratchet 31 and a second rotation angle detection unit 32. The ratchet 31 is disposed on the bead chain 12, and the second rotation angle detection unit 32 may be connected to the ratchet 31. The function of the second rotation angle detection unit 32 is to measure the rotation angle of the ratchet 31.

In this embodiment, the surrounding element of the cable module 1 may be a bead chain 12, and the bead chain 12 may include a surrounding portion 12a, which may be a part of the bead chain surrounding the user's limb 100, such as an arm . The bead chain 12 has the characteristics of being flexible but not scalable. The scroll wheel 21 can be placed on the arm, and rolls from the beginning of the arm to be measured and recorded. More specifically, the roller 21 can move along the long axis of the arm, and the first rotation angle detection unit 22 simultaneously measures the angle when the roller 21 rotates. The first rotation angle detection unit 22 can transmit the detected rotation angle value to an external arithmetic processing device 4, such as a mobile device or a computer. The arithmetic processing device 4 instantly calculates the distance moved by the first measurement module 2 from the acquired rotation angle. When the roller 21 rolls from the beginning of the arm to the end of the arm, the distance moved by the first measurement module 2 is the length of the arm.

Due to the thickness of each part of the arm, when the device moves in the direction of the long axis of the arm, the circumference of the arm changes, and the surrounding portion 12a sliding along the periphery of the arm under the fixed tensile force of the connecting line 11 will cooperate with the arm to extend or shrink. In an embodiment, the cable module 1 may further include a fixed tension spring group 13 and a fixed shaft 14. In this embodiment, the constant tension spring group 13 refers to a tension spring with a predetermined specific spring coefficient.

As for the other end of the connecting wire 11, it is connected to a constant tension spring group 13, and a spiral spring coil is provided inside the constant tension spring group 13. As the circumference of the arm changes, the length of the surrounding portion 12a increases and decreases. At this time, the helical spring coil inside the constant tension spring group 13 expands and contracts, and pulls the connecting wire 11 and the bead chain 12 to move it. In order to maintain the fixed tension on the connection line and the bead chain. Since the ratchet 31 engages with the bead chain 12, the movement of the bead chain 12 simultaneously drives the ratchet 31 to rotate. Next, the second rotation angle detection unit 32 simultaneously measures and records the rotation angle of the ratchet 31 at the positions of the arms of different lengths. The second rotation angle detection unit 32 may also transmit the detected rotation angle value to an external processing device 4 such as a mobile device or a computer. The arithmetic processing device 4 instantly calculates the length of the surrounding portion 12a based on the rotation angle value of the ratchet 31, and this length is the arm circumference.

At the same time, the first link module 5 can also pull the bead chain 12 through a groove (not shown) provided under the horizontal horizontal plate, so that the bead chain 12 is synchronized with the roller 21 along the long axis of the limb 100 mobile.

Please refer to FIG. 3, which is a schematic diagram of the dual cable module of the present invention. The limb circumference detection device of the present invention may include a double cable module 6 whose function is the same as that of the first link module 5 shown in FIG. 2. In one embodiment, the roller 21 may be installed on the horizontal cross plate 61 pulled down by the pulling force of the dual cable module 6 at both ends, and the horizontal force is pulled down by the pulling force of the dual cable module 6 at the same time. Board 61 drops. In addition, the horizontal horizontal plate 61 not only allows the roller 21 to be perpendicular to the surface of the limb 100 to be measured at any time, but also presses the roller 21 to adhere to the surface of the limb 100 and roll. At the same time, the double cable module 6 can also pull the bead chain 12 through a groove (not shown) attached under the horizontal cross plate 61 to keep the bead chain 12 along with the roller 21 along the long axis of the limb 100 Move synchronously.
