(Flexible film 10)
In some examples, the flexible membrane 10 may include a main body portion 100, a transition portion 110, and a deformation portion 120. In some examples, the body portion 100 may have a hollow channel 101 (see fig. 8). In some examples, the transition 110 may be located at one end of the hollow channel 101. In some examples, the deformation 120 may have a through hole 121 (described later in connection with fig. 5 or 6). In some examples, the deformation 120 may be provided to the main body portion 100 via the transition portion 110. In some examples, the hollow passage 101 may communicate with the through-hole 121.
In some examples, the young's modulus of the deformation portion 120 may be not greater than the young's modulus of the transition portion 110. That is, in some examples, the Young's modulus of the deformation portion 120 may be equal to the Young's modulus of the transition portion 110. In some examples, the young's modulus of the deformation portion 120 may be less than the mode modulus of the transition portion 110.
In some examples, the transition 110 may be annular. That is, the transition portion 110 may be located entirely at the outer periphery of the deformation portion 120.
In this case, the deformable portion 120 is elastically connected to the main body portion 100 via the annular transition portion 110, and the transition portion 110 can be deformed in an adaptive manner during the deformation of the deformable portion 120 by a force, thereby providing the flexible membrane 10 having a small volume, which is easily deformed.
(physical therapy equipment 1)
Referring to fig. 2, in some examples, the physiotherapy instrument 1 may include a host 30 and a negative pressure device 20. In some examples, the negative pressure device 20 may include an air pump 21 and an air pipe 22. The air pump 21 is used to generate and transmit air pressure to the flexible membrane 10 through the air pipe 22. In some examples, gas conduit 22 may include a connecting line (not shown) and a treatment head 221.
In some examples, the flexible membrane 10 may be used in conjunction with a negative pressure device 20. In some examples, the flexible membrane 10 may be sleeved around the outer circumference of the gas conduit 22. In the embodiment of the present invention, the flexible film 10 may be sleeved on the outer periphery of the treatment head 221 of the gas pipeline 22. Therefore, air pressure can be applied to the flexible membrane 10 through the negative pressure device 20, and the flexible membrane 10 is driven to move or deform through the action of the air pressure so as to massage the skin. In some examples, the flexible membrane 10 may be detachably mounted to the therapy head 221. In some examples, the main body portion 100 of the flexible membrane 10 may be fitted around the periphery of the therapy head 221 in an interference fit manner. This improves the air tightness of the connection between the flexible membrane 10 and the treatment head 221. In addition, the stability of the flexible film 10 when it is attached to the treatment tip 221 can be improved.
(working principle)
Fig. 4a and 4b are schematic views showing that the flexible membrane 10 according to the embodiment of the present invention is assembled to the negative pressure device 20 and massages the skin 2.
In some examples, the host 30 can control the operation state of the negative pressure device 20, and when the flexible membrane 10 is assembled on the treatment head 221, the negative pressure device 20 can cooperate with the flexible membrane 10 under the control of the host 30 to massage the skin 2.
Referring to fig. 4a and 4b, in some examples, when the air pressure inside the treatment head 221 is less than the ambient air pressure, the treatment head 221 may pull the skin 2 in a vertical direction. When the internal air pressure of the therapy head 221 is not less than the external air pressure, the skin 2 is restored due to the elasticity, i.e. the skin 2 is in a relaxed state. The skin 2 is pulled and relaxed by controlling the treatment head 221. Thus, being able to change the shape of the interfacial film of the various tissues of the skin 2 allows for blunt separation of the different tissue layers for mechanical massage of the skin 2.
In some examples, the degree of deformation of the flexible membrane 10 and the skin 2 is not always the same during the massage. This means that the flexible membrane 10 may also exert a squeezing action on the skin 2 during the massage. In some examples, massage may refer to the sum of the squeezing action applied by the flexible membrane 10 to the skin 2 and the action of the treatment head 221 pulling, relaxing the skin 2.
In some examples, the flexible membrane 10 may be provided with crush lobes thereon. This can improve the massage effect of the flexible film 10.
Fig. 5 is a schematic diagram illustrating a flexible film 10 according to an embodiment of the present invention at a first viewing angle. Fig. 6 is a schematic diagram illustrating a flexible film 10 according to an embodiment of the present invention at a second viewing angle. Fig. 7 is a schematic diagram illustrating a flexible film 10 according to an embodiment of the present invention at a third viewing angle. Fig. 8 is a schematic sectional view showing the flexible film 10 involved in fig. 1 along the A1a2 direction. Fig. 9 is an enlarged view showing the U-shaped transition portion 110 according to fig. 1.
(through hole 121)
In some examples, the number of the through holes 121 may be plural. In some examples, the number of vias 121 may be 1, 2, 3, 4, 5, 6, 7, 8, 9, 10. In some examples, the plurality of through-holes 121 may be uniformly arranged around the center of the deformation part 120. Referring to fig. 5 or 6, the plurality of through holes 121 may include a first air hole 121a, a second air hole 121b, and a third air hole 121 c. In the present invention, the first air holes 121a, the second air holes 121b, and the third air holes 121c may be uniformly arranged around the center of the deformation part 120. In this case, when the flexible film 10 is assembled to the physiotherapy apparatus 1 to massage the skin 2, the negative pressure device 20 of the physiotherapy apparatus 1 can act on the skin 2 through the plurality of through holes 121, whereby the massage effect can be improved.
(deformation part 120)
In some examples, the deformation 120 is concave towards the hollow channel 101.
In some examples, the surface of the deformation 120 facing away from the hollow channel 101 may be spherical. In this case, the surface area of the deformed portion 120 can be increased to some extent, and thus the massage effect can be improved. Specifically, in the case where the projected area is substantially equal to the cross-sectional area perpendicular to the longitudinal direction of the hollow passage 101, the spherical deformation portion 120 has a large actual surface area. In this case, the area of the deformation portion 120 can be increased appropriately in a limited space.
(Main body 100)
In some examples, the body portion 100 may be hollow cylindrical. In some examples, the length of the body portion 100 may be greater than half of its outer diameter. In some examples, the length of the body portion 100 may be no greater than twice its outer diameter. In some examples, the length of the body portion 100 may be adjusted according to the shape of the therapy head 221. This allows the main body 100 to be easily attached to the treatment head 221, and ensures high airtightness.
In some examples. The longitudinal direction of the body 100 may be substantially parallel to the central axis of the deformable portion 120. That is, the extending direction of the body 100 is substantially parallel to the central axis of the deformation part 120. In some examples, the central axis of the deformation 120 may refer to a straight line passing through the center of the outer surface and the center of the inner surface of the deformation 120.
(transition part 110)
In some examples, the outer diameter of the transition portion 110 may be greater than the outer diameter of the body portion 100. It should be noted that, in the present invention, the division of the flexible film 10 into a plurality of regions (for example, the main body portion 100, the deformation portion 120, and the transition portion 110) mainly serves for convenience of description. In some examples, there is no strict demarcation between the main body portion 100, the transition portion 110, and the deformation portion 120. In some examples, the transition portion 110 and the deformation portion 120 may be interpreted together as a "region that is deformable under force".
In some examples, the transition portion 110 may be U-shaped in cross-section along a radial direction of the transition portion 110 (see fig. 8, 9). In the present invention, a section along a radial direction of the transition portion 110 may refer to a plane passing through a diameter of the transition portion 110 and a central axis of the deformation portion 120. In this case, the transition portion 110 is easily deformed by the deformation portion 120, and thus the difficulty of the flexible film 10 being deformed by force can be reduced. In addition, since the transition portion 110 has a U-shape, the effect of the main body portion 100 in suppressing the deformation of the deformable portion 120 can be improved. It will be appreciated that the cross-sectional shape should be the same or substantially similar in any cross-section along the radial direction of the transition 110.
It can be understood that, in the present invention, the "region deformable by force" is mostly a "curved surface type" structure. Compared with a plane structure, the ' curved surface type ' structure can reasonably increase the area of the ' region which can be deformed by being stressed, so that the ratio of the area to the thickness of the ' region which can be deformed by being stressed ' can be increased, and the flexible membrane 10 is more sensitive to the reaction of acting force.
In some examples, the inner surface of the transition portion 110 may be concave. In some examples, the inner surface of the transition portion 110 is connected with the inner surface of the main body portion 100 forming the hollow channel 101. In this case, when the flexible membrane 10 is assembled to the physiotherapy apparatus 1 to massage the skin 2, the negative pressure device 20 of the physiotherapy apparatus 1 can easily pull the deformation part 120 to move toward the hollow passage 101, whereby the massage effect can be improved.
In some examples, the main body portion 100 and the deformation portion 120 may be connected to both sides of the opening of the transition portion 110, respectively. Specifically, in some examples, two sides of the opening of the transition portion 110 may be respectively denoted as 110a and 110b (see fig. 8), wherein 110a may refer to a portion where the transition portion 110 and the main body portion 100 are connected, and 110b may refer to a portion where the transition portion 110 and the deformation portion 120 are connected. In this case, since the transition portion 110 has a U-shaped cross section, the movable range of the deformable portion 120 can be increased when the main body portion 100 and the transition portion 110 are located on both sides of the opening.
In some examples, the main body portion 100, the morphable portion 120, and the transition portion 110 may be integrally formed. This can improve the airtightness of the flexible film 1.
According to the present invention, a flexible membrane 10 that can be adapted to a small treatment head 221 and is easily deformed can be provided.
It should be noted that the proportions of the respective portions in the respective drawings may be different from the actual proportions of the respective portions, and only for the purpose of assisting the explanation, the present invention is described below. And should not be construed as limiting.
While the present invention has been described in detail in connection with the drawings and examples, it is to be understood that the above description is not intended to limit the invention in any way. The present invention may be modified and varied as necessary by those skilled in the art without departing from the true spirit and scope of the invention, and all such modifications and variations are intended to be included within the scope of the invention.
