Description

Limb circumference detection device, and limb compliance measurement device and lymphedema treatment device formed by utilizing same

Technical Field

The present invention relates to a device for detecting the circumference of a limb, and more particularly, to a device for continuously measuring the circumference of each position of a limb and performing compliance measurement and edema treatment of the limb.

Background

After the patients with breast cancer, gynecologic or pelvic cancer are treated by operation, the lymph circulation path is blocked because the tissue fibrosis is caused by lymph node resection and subsequent radiotherapy and chemotherapy. The accumulation of lymph fluid in the tissues causes swelling, called lymphedema, which is more likely to occur especially in the four limbs.

Lymphedema is caused by the loss of balance in the exudation and recovery of lymph, and therefore, lymphedema usually does not occur immediately after surgery and chemotherapy, but rather develops after months or even years. Lymphedema can cause the appearance, confidence and function of daily living of a patient to be severely affected.

In view of the good early treatment effect after lymphedema is developed, a patient needs a convenient device to monitor the circumference of the limb after operation, radiotherapy and chemotherapy so as to track whether lymphedema is developed. In addition, the data of the limb circumference of the patient can be recorded, so that medical personnel can adjust the contents of the rehabilitation plan according to the condition of the patient, and the rehabilitation plan is more suitable for the patient.

Furthermore, clinical experience has shown 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 effectiveness of the treatment, and therefore measurement is necessary. The lymphedema can be relieved by the bare-handed lymphatic drainage, but the bare-handed lymphatic drainage needs to be executed by professionals, so that the labor of the professionals is consumed, and the manual lymphatic drainage needs to be executed in medical institutions.

Therefore, how to design a detection device capable of rapidly and accurately measuring the circumference of the limb and the compliance of the limb and having edema treatment effect is a problem to be overcome in the present industry.

In the meantime, as cited in the present specification

And the terms are used for clarity of description, and are not intended to limit the scope of the invention, and changes or modifications in the relative relationship may be made without substantial technical changes and alterations as long as the invention is considered to be within the scope of the invention.

Referring to fig. 1, fig. 1 is a first schematic view of a limb circumference detecting device of the present invention. The invention provides a limb circumference detection device, which comprises a pull wire module 1, a first measurement module 2 and a second measurement module 3. The pull module 1 includes a ring assembly, which can be disposed around the limb 100, and the first measurement module 2 and the second measurement module 3 are disposed on the pull 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 meanwhile, the second measurement module 3 simultaneously measures the length of the pull module 1 surrounding the limb 100, i.e. the circumference of the limb 100. The limb 100 may comprise an upper limb or a lower limb, and in the embodiment of the present invention, the upper limb is taken as an example.

In the embodiment shown in fig. 1, the wire drawing module 1 may include a connecting wire 11, and the surrounding component may be, for example, a bead chain 12 sleeved on the connecting wire 11, wherein the bead chain 12 has a flexible but non-stretchable characteristic. The first measuring module 2 may include a roller 21 and a first rotation angle detecting unit 22 connected to the roller 21. The first rotation angle detecting unit 22 is used for measuring the rotation angle of the roller 21. The second measuring module 3 may include a ratchet wheel 31 and a second rotation angle detecting unit 32, the ratchet wheel 31 is disposed on the bead chain 12, and the second rotation angle detecting unit 32 may be connected to the ratchet wheel 31. The second rotation angle detecting unit 32 is used for measuring the rotation angle of the ratchet 31.

In the present embodiment, the encircling element of the module 1 can be a bead chain 12, and the bead chain 12 can include an encircling portion 12a, and the encircling portion 12a can be a portion of the bead chain that encircles the limb 100 of the user, such as an arm. The bead chains 12 have flexible but non-stretchable properties. The roller 21 can be placed on the arm and starts to roll 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 synchronously measures the rotation angle of the roller 21. The first rotation angle detecting unit 22 may transmit the detected rotation angle value to an external operation processing device 4, such as a mobile device or a computer. The operation processing device 4 calculates the moving distance of the first measuring module 2 in real time 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.

Because the thickness of each part of the arm is divided into different parts, when the device moves along the long axis direction of the arm, the circumference of the arm changes, and the surrounding part 12a sliding along the periphery of the arm can extend or contract along with the circumference of the arm under the fixed tension of the connecting line 11. In an embodiment, the wire pulling module 1 may further include a fixed tension spring set 13 and a fixed shaft 14. In the present embodiment, the fixed tension spring set 13 refers to a tension spring with a default specific elastic coefficient. One end of the bead chain 12 can be connected to the fixed shaft 14, and the other end of the bead chain 12 is connected to one end of the connecting wire 11. In another embodiment, the limb circumference detecting device of the present invention may further include a ball chain pulley (not shown) mounted on the fixed shaft 14, in this embodiment, one end of the ball chain 12 is connected to one end of the connecting line 11, and after the ball chain 12 turns around the pulley, the other end of the ball chain 12 is connected back to the connecting line 11, so as to reduce the moving distance between the end of the ball chain 12 and the connecting line 11. The other end of the connecting wire 11 is connected to a fixed tension spring set 13, and a spiral spring coil is arranged in the fixed tension spring set 13. The length of the surrounding portion 12a is increased or decreased with the change of the size of the arm circumference, and at this time, the helical spring coil inside the constant tension spring set 13 is rotated to expand or contract, and the connecting wire 11 and the bead chain 12 are pulled to move, so as to maintain the fixed tension on the connecting wire and the bead chain. Since the ratchet wheel 31 is engaged with the bead chain 12, the movement of the bead chain 12 will simultaneously drive the ratchet wheel 31 to rotate. Then, the second rotation angle detection unit 32 synchronously measures and records the rotation angle of the ratchet wheel 31 at different length positions of the arm. The second rotation angle detecting means 32 may transmit the detected rotation angle value to the arithmetic processing device 4 such as an external mobile device or a computer. The arithmetic processing unit 4 calculates the length of the surrounding portion 12a, which is the arm circumference, in real time based on the numerical value of the rotation angle of the ratchet 31.

Referring to fig. 2, fig. 2 is a schematic view of a first link module according to the present invention. The limb circumference detecting device of the present invention may further include a first link module 5. The first link module 5 is designed according to the geometric principle that the middle point of the hypotenuse of the right triangle is equidistant from three vertexes, and the roller 21 can be installed on the horizontal cross plate 51 under the first link module 5. The horizontal plate can make the roller 21 perpendicular to the surface of the limb 100 to be measured at any time, and a tension spring (not shown) can be arranged in the first link module 5, so that the horizontal plate 51 is pressed to descend by the action of the tension spring, and the roller 21 is further pressed to be attached to the surface of the limb 100 to roll. Meanwhile, the first link module 5 can pull the bead chain 12 through a groove (not shown) attached below the horizontal cross plate, so that the bead chain 12 keeps moving synchronously with the roller 21 along the long axis of the limb 100.

Referring to fig. 3, fig. 3 is a schematic view of a dual wire module according to the present invention. The limb circumference detecting device of the present invention may further include a double-pull module 6, which functions as the first link module 5 shown in fig. 2. In one embodiment, the roller 21 may be installed on the horizontal plate 61 with both ends pulled down by the pulling force of the dual wire pulling module 6, and the horizontal plate 61 is lowered by the pulling force of the dual wire pulling module 6 simultaneously pulling the pulling force. Furthermore, the 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 be attached to the surface of the limb 100 to roll. Meanwhile, the double-pull module 6 can pull the bead chain 12 through a groove (not shown) attached below the horizontal transverse plate 61, so that the bead chain 12 keeps moving synchronously with the roller 21 along the long axis direction of the limb 100.

It should be noted that the limb circumference detecting device of the present invention may be used in the first link module 5 shown in fig. 2 and the double-pull module 6 shown in fig. 3, either one of them may be selected for use in implementation, or both of them may be selected for use.

Referring to fig. 4, fig. 4 is a schematic view of a limb circumference detecting device according to a second embodiment of the present invention. In the embodiment, the wire drawing module 7 includes a surrounding element that can be disposed around the limb 100, a fixed tension spring set 71, and a connecting wire 72 with one end connected to the fixed tension spring set 71, and the surrounding element can be, for example, a measuring wire 73 connected to the other end of the connecting wire 72. In use, the encircling component of the wire pulling module 7, in this embodiment the measuring wire 73, may comprise an encircling portion 73a, which encircling portion 73a may be the portion of the measuring wire encircling the limb 100 of the user, such as an arm. The measuring wire 73 may be made of plastic, metal or cotton yarn. The measuring wire 73 has the property of being flexible but not stretchable.

In another aspect, the present invention may also use an optical motion sensor to replace the angle detection unit, and the first measurement module 2 and the second measurement module 3 may respectively include a first optical motion sensing unit 23 and a second optical motion sensing unit 33. The first optical motion sensing unit 23 can be disposed at the contact position of the circumference detection device of the present invention and the upper skin of the limb 100, and drives the first measurement module 2 and the measurement line 73 to move synchronously when the circumference detection device moves along the length direction of the limb 100. The first optical motion sensing unit 23 is used for sensing the distance moved along the length of the limb 100, and measuring the length of the limb 100.

The second optical motion sensor unit 33 is disposed above the measurement line 73 for measuring the circumference of the limb 100. The second optical motion sensor unit 33 measures the circumference of the limb 100, namely, measures the moving distance of the measuring line 73 to obtain the circumference of the limb 100. Another possible way to measure the circumference of the limb 100 is to arrange the second optical motion-sensing unit 33 beside the side wall of the pulley (not shown in the figure) used for guiding the measuring line 73 to turn, measure the rotation arc of the pulley and convert it into the moving distance of the measuring line 73, and obtain the circumference of the limb 100. Since the connecting line 72 and the measuring line 73 have the same moving distance, the second optical motion sensor unit 33 can be disposed above the connecting line 72 to measure the moving distance of the connecting line 72, or can be disposed near the side wall of the pulley for guiding the connecting line 72 to turn, and the rotating arc of the pulley can be converted into the moving distance of the connecting line 72.

The length of the limb 100, which is obtained from the distance moved by the first optical motion-sensing unit 23 along the length of the limb 100, and the circumference of the limb 100, which is obtained from the distance moved by the second optical motion-sensing unit 33 to measure the measurement line 73 (or the connection line 72), can be transmitted to an external computing device 4, such as a mobile device or a computer. The pulley angle measured by the second optical motion sensor unit 33 can also be converted into the moving distance of the measurement line 73 (or the connection line 72) by converting the pulley rotation radian through the calculation processing device 4, so as to obtain the circumference of the limb 100.

Referring to fig. 4 and 5, fig. 5 is a schematic view of a second link module according to the present invention. The circumference detecting device of the present invention may further include at least one guide clamping block 80 and a second link module 81. In this embodiment, the circumference detecting device of the present invention includes a plurality of guiding blocks 80, and the guiding blocks 80 may be disposed on the measuring line 73a evenly or unevenly and be disposed around the limb 100. The second link modules 81 are installed at both sides and bottom side of the circumference detecting device, and each guide clamping block 80 is installed at the second link module 81, so that the guide clamping blocks 80 are attached to the surface of the limb 100, and the measuring line 73 can be attached to the surface of the limb 100 at any time when the circumference detecting device moves.

In detail, the second link module 81 includes an outer frame 810, a first link 811, a second link 812 and a horizontal link 813. The frame 810 substantially surrounds the limb and has a stripe of slots 8101, wherein the stripe of slots 8101 may be substantially perpendicular to the long axis direction of the limb. The horizontal link 813 has two ends, one end of which is clamped in the bar slot 8101 and is substantially perpendicular to the bar slot 8101. The first link 811 has two ends, and one end thereof is slidably engaged with the bar-shaped slot 8101. The second link 812 has two ends, and one end thereof is pivotably connected to the first link 811. The outer frame 810, the horizontal link 813, the first link 811, and the second link 812 are respectively connected to the corresponding guide blocks 80. The horizontal link 813 is provided at a position near the bottom side of the limb 100 in the limb circumference detection device, and the first link 811 and the second link 812 are located above the horizontal link 813 for guiding the measuring line 73 to be in close contact with the surface of the limb 100. The lifting mechanism of the horizontal link 813 can be designed by the same link mechanism as shown in the link module 5 in fig. 2, or by the same double-wire-pulling mechanism as shown in the double-wire-pulling module 6 in fig. 3.

Referring to fig. 6, fig. 6 is a schematic view of a device for measuring compliance of a limb. As shown, the compliance measuring device of the limb 100 includes two sets of pull-wire modules 7 (including the set of constant tension springs 71, the connecting wires 72 and the measuring wires 73), at least one set of first measuring modules 2 (including the first optical motion sensing unit 23) and two sets of second measuring modules 3 (including the second optical motion sensing unit 33). The two groups of guy wire modules 7 are respectively arranged around the limb 100 and are adjacent to each other. The two groups of stay wire modules 7 apply different tensile strengths respectively for monitoring the difference change of the hardness of the limb 100. The first optical motion sensing unit 23 is disposed on the wire drawing module 7, and is used for moving along the long axis direction of the limb 100 and measuring the length of the limb 100 at the same time. Two sets of second optical motion sensing units 33 are disposed on the two wire pulling modules 7, and the second optical motion sensing units 33 are configured to measure the length of each corresponding surrounding portion 73a synchronously when the first optical motion sensing unit 23 moves along the long axis direction of the limb 100, so as to obtain the circumference of the limb 100.

The device for measuring the compliance of the limb of the present invention can be regarded as a device for detecting the circumference of the limb of the present invention, which is combined with at least one of the pull line modules, preferably, the pull line modules can be arranged in parallel, and more preferably, the tension-fixing spring sets of the pull line modules can have the same or different tension strengths selectively. By connecting two groups of pull wire modules with different pulling forces in parallel, the pull wire modules synchronously move along the long axis direction of the limb 100, the circumference data of the same limb position under the condition of different pulling forces (namely the tightness of the measuring wire) is measured and obtained in real time, and the difference of the two groups of data can be converted into the hardness degree of the limb 100. In other words, the difference in tightness caused by different tensile strengths causes the variation in the circumference measurement of the limb, and this variation reflects the degree of softness (compliance) of the limb, thereby monitoring the variation in the compliance of the limb.

Referring to fig. 7, fig. 7 is a schematic view of a lymphedema treatment apparatus. The lymphedema treatment device comprises a limb circumference detection device and a plurality of pull wire modules 7 (comprising fixed pull spring sets 71, connecting lines 72 and measuring lines 73), wherein the pull wire modules 7 are respectively arranged around a limb 100 and are adjacent to each other, each set of pull wire modules 7 is used for applying default pull strength, and more specifically, each set of pull wire modules has different pull strengths according to different treatment conditions. In an embodiment of the present invention, the lymphedema treatment apparatus may further include at least one first measurement module 2 (including the first optical motion sensing unit 23) and at least one second measurement module 3 (including the second optical motion sensing unit 33). At least one first optical motion sensing unit 23 is disposed on a corresponding pull line module 7 for moving along the long axis direction of the limb 100 and measuring the length of the limb 100 at the same time. At least one second optical motion sensing unit 33 is disposed on the same pull module 7, and the second optical motion sensing unit 33 is configured to measure the length of the corresponding surrounding portion 73a synchronously when the corresponding first optical motion sensing unit 23 moves along the long axis direction of the limb 100, so as to obtain the circumference of the limb 100.

In the embodiment of the limb compliance measuring device and the lymphedema treatment device of the present invention, the distance between the pull wire modules may be adjusted according to the design of the components and the condition of the limb 100 of the patient, and preferably, may be set to be between 10 mm and 100mm, but not limited thereto.

As mentioned above, the lymphedema treatment device of the present invention includes a limb circumference detection device of the present invention and a plurality of the pull wire modules, and different tensile strengths are applied by the fixed tension spring sets 71 of the pull wire modules. Preferably, the lymphedema treatment device can be formed by combining a limb circumference detection device of the invention and 2 to 9 pull wire modules. In the present embodiment, the constant tension spring set 71 of each wire pulling module 7 has different predetermined tensions. When each of the pull wire modules 7 is pulled along the arm in a fixed direction, each of the measuring wires 73 simultaneously applies pressure to the surface of the limb 100, thereby generating a therapeutic effect. The therapeutic principle is that proper pressure is applied to the affected part to stimulate the smooth muscle on the lymph duct to shrink, and the proper drainage direction is matched to redirect the lymph fluid between tissues to superficial circulation and then to other normal function lymph nodes via the anastomotic part of superficial circulation to redirect the redundant lymph fluid back to blood circulation.

Fig. 8 is a schematic view of a third embodiment of a limb circumference detecting device. As shown in fig. 8, the limb circumference detecting device of the present invention may further include a third link module 82 and at least one guide clamp block 80. The third link module 82 may include a grip 820, two third links 821, and two fourth links 822. The grip 820 can be held by a user, and the constant tension spring assembly 71 is disposed on the grip 820. The first end 8211 of the third link 821 may be connected to the handle 820 and the second end 8212 of the third link 821 may be connected to the first end 8221 of the fourth link 822. The second end 8222 of the fourth link 822 may be connected to the guide clamp block 80. The third and

fourth links

821, 822 substantially encircle the user's limb 100 and secure the guide clamp block 80.
