Description

Technical Field

[0001] The present application relates to the technical field of medical auxiliary equipment, and in particular to an upper limb massage device and a method of using the same. Background Art

[0002] Massage is the act of squeezing or stretching the muscles under the skin to dredge the meridians and lubricate the joints. The massage device can replace the human hand to stimulate the local limbs through mechanical vibration.

[0003] In the prior art, a limb massager (application number: 202321051645.9) is disclosed. The limb massager is provided with a pressurized airbag installed on the inner side of a binding massage belt. After the patient's upper limb is fixed inside the binding massage belt, the air pump runs through the air pipe to inflate the inside of the pressurized airbag. During the continuous inflation and deflation process of the pressurized airbag, the patient's upper limb will be squeezed and relieved by the pressurized airbag, thereby achieving massage of the patient's upper limb. However, when using an airbag for massage, the outer contact area with the skin is large, and it is impossible to press the acupoints in a targeted manner. Although massage can be achieved, the effect of acupoint massage may be poor. In addition, some protrusions are added to the surface of the airbag for pressing the acupoints. After being inflated, the airbag will swell. After swelling, these protrusions may be displaced or deformed, and there is no guarantee that the corresponding acupoints can be pressed. Therefore, the effect of acupoint massage may not be very good. Summary of the invention

[0004] The technical problem to be solved by the present application is to provide an upper limb massage device and a method of using the same, which can accurately press the corresponding acupuncture points on the arm.

[0005] In order to solve the above technical problems, this application adopts the following technical solutions:

[0006] An upper limb massage device comprises a fixing component and a pressing component;

[0007] The fixing assembly includes an annular shell, the outer wall of the annular shell is provided with a driver, the interior of the annular shell is provided with an annular component controlled to rotate by the driver, the annular component includes a rotating gear and a circular ring, the circular ring is provided at the inner wall of the rotating gear, and the inner wall of the circular ring is provided with a plurality of pressing protrusions;

[0008] The pressing assembly is arranged in the annular shell, and includes a telescopic rod, which movably passes through the outer side wall of the annular shell, and one end of the telescopic rod facing the center of the annular shell is connected to a pressing plate, and the end surface of the pressing plate facing the center of the annular shell is provided with a massage column staggered with the telescopic rod, and the massage column movably passes through the inner side wall of the annular shell, and a spring is sleeved on the massage column, and the spring is arranged between the pressing plate and the movable shell;

[0009] When the annular component rotates, the pressing protrusion presses the pressing plate to move the pressing assembly toward the center of the annular shell.

[0010] The driver drives the annular component to rotate in the annular shell, and a plurality of pressing protrusions on the inner wall of the annular ring sequentially press the pressing component to move toward the skin, and the massage column of the pressing component can press the corresponding acupuncture points.

[0011] In order to fix the upper limb massage device on the arm, in some embodiments, the inner side walls at the front and rear ends of the annular shell are respectively provided with air bag rings.

[0012] In order to enable the driver to drive the annular component to rotate, in some embodiments, the driver includes a motor and a transmission gear, the motor shaft can rotatably penetrate into the interior from the outer wall of the annular shell, and the transmission gear is arranged on the motor shaft and is located inside the annular shell.

[0013] According to a further development of the above scheme, the rotating gear is an end gear, which is meshed with the transmission gear.

[0014] In order to prevent the telescopic rod from escaping from the annular housing, in some embodiments, a limiting flange is provided on the telescopic rod, and the limiting flange is located inside the annular housing.

[0015] A method for using an upper limb massage device comprises the following steps:

[0016] Step 1: Wear the upper limb massage device at the corresponding position of the arm, and inflate the airbag ring to fix the upper limb massage device on the arm;

DETAILED DESCRIPTION

[0029] The present application will be described in detail below with reference to the exemplary embodiments in the accompanying drawings. However, it should be understood that the present application can be implemented in a variety of different forms and should not be construed as being limited to the embodiments described herein. These embodiments are provided here to make the disclosure of the present application more complete and to fully convey the concept of the present application to those skilled in the art.

[0030] In the description of the present application, it should be understood that the terms "center", "lateral", "longitudinal", "front", "back", "left", "right", "up", "down", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the scope of protection of the present application.

[0031] In view of the defect in the prior art that the corresponding acupoints on the arm may be accurately pressed, resulting in poor effect of acupoint massage. After careful analysis, the inventor found that the main reason for the above problem is that some current massagers, such as limb massagers (application number: 202321051645.9) and a massage glove for preventing insufficient blood perfusion of distal and proximal arteries of the upper limbs (application number: 202020155266.4), all use airbags to press the patient's skin, but the airbag body is a flat or curved structure, and the contact with the skin is mostly surface contact, that is, it is difficult to continue pressing after a certain pressure, so it is impossible to press the acupoints; although some protrusions are added to the surface of the airbag for pressing the acupoints, after the airbag is inflated, the body bulges, and the protrusions on the surface of the airbag may swing or move after the bulge, causing the protrusions of these pressing acupoints to be offset and unable to press the corresponding acupoints. Based on the above analysis, the inventor made structural improvements to the upper limb massager.

[0032] like Figure 1-7 As shown, in at least one embodiment of the upper limb massage device of the present application, it includes a fixing component fixed at any position of the patient's arm and a pressing component for pressing acupuncture points;

[0033] The fixing assembly includes an annular shell 1 made of transparent plastic, the annular shell 1 is formed by hot-melt connection of two semicircular hollow tubes, a driver is provided on the outer wall of the annular shell 1, an annular component controlled to rotate by the driver is provided inside the annular shell 1, the annular component includes a rotating gear 19 and a ring 16 made of plastic, a slot for arranging the rotating gear 19 is provided inside the annular shell 1, the rotating gear 19 is installed in the slot inside the annular shell 1 with a gap, a through hole is provided in the middle of the rotating gear 19, the ring 16 is connected to the inner wall of the rotating gear 19 by glue, and a plurality of hemispherical pressing protrusions 15 are equidistantly provided on the circumference of the inner wall of the ring 16;

[0034] The ring 16 and the pressing protrusion 15 can be integrally formed by injection molding;

[0035] The pressing assembly made of plastic is arranged in the annular shell 1, and includes a telescopic rod 2, which movably passes through the outer wall of the annular shell 1, and one end of the telescopic rod 2 facing the center of the annular shell 1 is connected with a tile-shaped pressing plate 14, and the pressing plate 14 is located in the annular shell 1, and the end surface of the pressing plate 14 facing the center of the annular shell 1 is provided with a massage column 13 staggered with the telescopic rod 2. More specifically, as Figure 2 and Figure 3 As shown, the telescopic rod 2 is located at the top right side of the pressing plate 14, and the massage column 13 is located at the bottom left side of the pressing plate 14, thereby forming a staggered distribution. The massage column 13 movably passes through the inner side wall of the annular housing 1, and a spring 10 is sleeved on the massage column 13, and the spring 10 is arranged between the pressing plate 14 and the movable housing;

[0036] When the annular component rotates, the pressing protrusion 15 presses the pressing plate 14 to move the pressing assembly toward the center of the annular shell 1. At this time, the spring 10 is compressed and the massage column 13 presses the corresponding acupuncture point. After the pressing protrusion 15 and the pressing plate 14 are separated, the spring 10 is no longer compressed, and its reaction force lifts the pressing plate 14 to reset the pressing assembly.

[0037] The inner side walls of the annular housing 1 at both ends are respectively attached with airbag rings 4, the main body of the airbag ring 4 is an annular airbag, and the existing inflation and deflation valve core is installed on the airbag ring 4, and the airbag ring 4 can be inflated through the valve core. After wearing the upper limb massage device and determining the installation position, the airbag ring 4 is inflated to make it swell and contact with the skin of the arm to generate friction, and the upper limb massage device is fixed on the arm. After the airbag ring 4 swells, it will form a height difference with the massage column 13, so that the massage column 13 can press the acupoints reciprocatingly by pressing the acupoints, then leaving the acupoints, and then pressing the acupoints again.

[0038] The function of the driver is to control the rotation of the annular component. The driver includes a motor and a transmission gear 23. A through hole is opened on the outer wall of the annular shell 1. The rotating shaft of the motor can rotatably penetrate into the interior through the through hole on the outer wall of the annular shell 1. The transmission gear 23 is installed on the rotating shaft of the motor and is located inside the annular shell 1.

[0039] The rotating gear 19 is preferably an end gear, and the transmission gear 23 is preferably a bevel gear to ensure that the two can be kneaded with each other.

[0040] In order to prevent the motor from falling off from the annular housing 1 , a cover 5 for fixing the motor is installed on the outer side wall of the annular housing 1 .

[0041] In order to achieve the effect that the telescopic rod 2 can be movably extended from the outer wall of the annular shell 1, and the massage column 13 can be movably extended from the inner wall of the annular shell 1, through holes for the telescopic rod 2 and the massage column 13 to pass through are respectively opened on the outer wall and the inner wall of the annular shell 1. Considering that after the upper limb massage device is fixed on the patient's arm by the airbag ring 4, if the position of the pressing component is to be adjusted, the airbag ring 4 needs to be deflated, but this step may take some time. In order to improve the efficiency of fine-tuning the pressing component, the through holes on the outer wall and the inner wall of the annular shell 1 for the telescopic rod 2 and the massage column 13 to pass through are respectively enlarged and set into cross-shaped and hollowed-out distance adjustment grooves 11, the telescopic rod 2 is arranged in the distance adjustment groove 11 of the outer wall of the annular shell 1, and the massage column 13 is arranged in the distance adjustment groove 11 of the outer wall of the annular shell 1, and can be fine-tuned horizontally or vertically (that is, when the telescopic rod 2 moves horizontally, the massage column 13 is driven by the pressing plate 14 to move in the same direction as the telescopic rod 2).

[0042] The telescopic rod 2 is provided with a limiting flange 21 , which is located in the annular housing 1 , and can prevent the spring 10 from lifting the pressing plate 14 too high, thereby causing the pressing protrusion 15 in the ring 16 to be unable to press over the pressing plate 14 .

[0043] The end of the massage column 13 is provided with a massage ball 3 , which can increase the pressing area without increasing the diameter of the massage column 13 .

[0044] The pressing component is fixed at any position in the distance adjustment slot 11 by the reaction force of the spring 10 and the upper limit flange 21 of the telescopic rod 2. However, due to vibration during use, the pressing component may be displaced during use. In order to solve this problem, Figure 2-4As shown, a U-shaped distance adjusting plate 20 (i.e., one end is open) made of plastic for adjusting the longitudinal movement and fixing of the pressing assembly is installed in the annular shell 1, and an adjusting rod 9 for adjusting the lateral movement and fixing of the pressing assembly is installed on the distance adjusting plate 20. The pressing plate 14 is movably arranged in the opening of the distance adjusting plate 20. A screw-shaped locking rod 6 is connected to the right end of the distance adjusting plate 20. An arc-shaped adjusting groove 12 for the locking rod 6 to pass through is opened at the rear end of the annular shell 1. A locking piece 7 (a nut) is provided on the locking rod 6. The locking piece 7 is located on the right side of the adjusting groove 12.

[0045] A through hole is provided at the rear end of the locking rod 6, and the through hole passes through the distance adjusting plate 20. The adjusting rod 9 is located in the through hole on the locking rod 6. A vertical guide rod 8 is connected to the front end of the adjusting rod 9. The pressing plate 14 in the distance adjusting plate 20 at this position is located in front of the connecting rod. A through hole is provided at the rear end of the pressing plate 14 for the guide rod 8 to pass through, and a avoidance groove is provided on the side wall of the through hole for the adjusting rod 9 to pass through. When the pressing plate 14 moves up and down, the connecting rod and the guide rod 8 will not interfere with its movement trajectory. It is worth noting that the diameter of the guide rod 8 should be larger than the adjusting rod 9, and the size of the through hole on the pressing plate 14 for the guide rod 8 to pass through is larger than the avoidance groove, so that when the adjusting rod 9 is moved, the guide rod 8 will not fall off the pressing plate 14.

[0046] A threaded hole is provided on the side wall of the locking member 7 , and a locking screw 22 is installed in the threaded hole to fix the position of the adjusting rod 9 .

[0047] In one embodiment, a method for using the upper limb massage device is also provided, comprising the following steps:

[0048] Step 1: Wear the upper limb massage device at the corresponding position of the arm, and inflate the airbag ring 4 to fix the upper limb massage device on the arm;

[0049] Step 2: The driver drives the annular component to rotate, and the pressing protrusions 15 in the annular component press the pressing plate 14, and the pressing plate 14 drives the massage column 13 to press the corresponding acupuncture points. The annular component continuously rotates so that the pressing protrusions 15 successively press the pressing components and move up and down through the reaction force of the spring 10, pressing back and forth;

[0050] Step 3: If the acupoint is not pressed, the control driver stops operating, and the telescopic rod 2 is adjusted in the distance adjustment slot 11 to adjust the position of the pressing component. The adjustment method is as follows: if the horizontal pressing component is adjusted, first loosen the locking screw 22, and then pull the adjusting rod 9, so that the adjusting rod 9 drives the pressing component to press the acupoint according to the adjustment groove 11. Figure 3 or Figure 4As shown, move to the right side (it can also be understood as moving along the axis of the annular shell 1) to find the acupuncture point. If it is necessary to find the acupuncture point along the circumference of the annular shell 1, loosen the locking member 7, so that the distance adjustment plate 20 at one end of the locking member 7 moves in the arc-shaped adjustment groove 12 at the rear end of the annular shell 1 to find the acupuncture point. After aligning the acupuncture point, tighten the locking member 7 and the locking screw 22 in turn, and then re-operate the driver to make the annular component rotate continuously so that a plurality of pressing protrusions 15 successively press the pressing assembly and move up and down through the reaction force of the spring 10, pressing back and forth.

[0051] The pressing plate 14 has a tile-shaped (i.e., arc-shaped) structure to ensure that the pressing protrusion 15 can smoothly press over the pressing plate 14 during its movement, and to prevent the end surface of the pressing plate 14 from being too flat and interfering with the movement of the pressing protrusion 15 .

[0052] Since the rotating gear 19 is installed in the slot of the annular housing 1 with clearance fit, it may shake and fall out during operation. The rear end of the rotating gear 19 is connected to the limit flange 17. The annular housing 1 is provided with an annular shallow groove for the limit flange 17 to engage. The limit flange 17 is located in the annular shallow groove to limit the escape of the rotating gear 19. In addition, in order to reduce the contact area between the outer wall of the rotating gear 19 and the inner wall of the annular housing 1, a circle of arc grooves is provided on the outer wall of the rotating gear 19, and a semicircular recessed groove is provided on the inner wall of the slot. A ball 18 is installed between the arc groove and the semicircular groove.

[0053] In one of the embodiments, the working principle of the upper limb massage device is also provided. After the driver is connected to an external power source, the motor rotates to drive the transmission gear 23 to rotate, and the transmission gear 23 drives the rotating gear 19 kneaded therewith to rotate. The circular ring 16 on the inner wall of the rotating gear 19 drives the pressing protrusion 15 to move along the trajectory of the rotation of the circular ring 16. During the movement of the pressing protrusion 15, it will contact the pressing plate 14 of the pressing assembly, and press the pressing plate 14 to move the massage column 13 toward the axis of the annular shell 1, and the annular shell 1 An arm is sleeved at the center, so that the massage column 13 presses the acupuncture points on the arm. When the pressing protrusion 15 continues to move following the trajectory of the rotation of the ring 16, it will separate from the pressing plate 14. The pressing plate 14 bounces back to its original position due to the reaction force of the spring 10 sleeved on the massage column 13, and the next pressing protrusion 15 contacts the pressing plate 14 during the movement of the ring 16, thereby continuing to press the pressing plate 14, so that the massage column 13 (or massage ball 3) continues to contact the acupuncture points for massage, thereby achieving precise reciprocating massage.

[0054] In addition, the device can be set into different sizes and used for upper arms, forearms, thighs, calves and other positions.

[0055] It should be understood that all the above embodiments are illustrative rather than restrictive, and various modifications or variations made by those skilled in the art to the specific embodiments described above based on the concept of the present application should all be within the protection scope of the present application.
