Description

Technical Field

[0001] This application relates to the field of pressurization device technology, and more specifically to a pressurization wearable protective sleeve. Background Technology

[0002] Compression therapy improves symptoms of conditions such as edema, venous disease, and elephantiasis by applying external pressure to the fingers to promote blood and lymphatic drainage. Currently, clinical practice primarily utilizes standard-sized compression garments, custom-made compression suits, elastic bandages, and adjustable compression devices for compression therapy.

[0003] Standard-sized compression garments, with their fixed dimensions, cannot precisely adapt to the diverse limb shapes of different patients. While custom-made compression garments can improve fit, they are prohibitively expensive. Elastic bandages, though offering better adaptability, rely entirely on the operator's experience for pressure control, making it difficult to guarantee accurate and consistent pressure values. Furthermore, bandages require frequent replacement, are inconvenient to use, and long-term use may lead to skin damage and other problems.

[0004] However, for patients with more severe elephantiasis, different types of wearable devices are needed as the disease is treated, but current adjustable pressure devices only have one type of wearable device. Utility Model Content

[0005] In order to overcome at least one deficiency of the prior art, this application provides a pressure-wearing cover with different wearing states.

[0006] To achieve the above objectives, this application provides a pressure-sensitive wearable sleeve, having at least a first wear state and a second wear state. The pressure-sensitive wearable sleeve includes a main body piece, a first connecting piece, and a second connecting piece. The first and second connecting pieces are detachably connected to opposite ends of the main body piece. The first connecting piece extends at least one first tension band from its end away from the connection with the main body piece, and the second connecting piece extends at least one second tension band from its end away from the connection with the main body piece. The at least one first tension band is detachably connected to the second connecting piece, and the at least one second tension band is detachably connected to the first connecting piece. When the pressure-sensitive wearable sleeve is in the first wear state, the first connecting piece, the second connecting piece, and the main body piece are all oriented in the same direction, with the first and second connecting pieces located on the left and right sides of the main body piece, respectively. When the pressure-sensitive wearable sleeve is in the second wear state, the first and second connecting pieces are oriented opposite to the main body piece, with the first and second connecting pieces located on the right and left sides of the main body piece, respectively.

[0007] The first connecting piece, the second connecting piece, and the main body piece all being oriented in the same direction can also mean that the larger ends of the first connecting piece, the second connecting piece, and the main body piece all face the same side. Alternatively, the first connecting piece, the second connecting piece, and the main body piece being oriented in opposite directions can also mean that the larger ends of the first connecting piece, the second connecting piece, and the main body piece are oriented in the same direction.

[0008] The first connecting piece, the second connecting piece, and the main body piece all being oriented in the same direction can also mean that the upper ends of the first connecting piece, the second connecting piece, and the main body piece all face the same side. Alternatively, the first connecting piece, the second connecting piece, and the main body piece being oriented in opposite directions can also mean that the upper ends of the first connecting piece, the upper ends of the second connecting piece, and the lower ends of the main body piece are oriented in the same direction.

[0009] The terms "right side" and "left side" are relative, representing only relative positions. The relative positions of the first and second connecting pieces within the main body will change depending on the wearing state. Similarly, "top" and "bottom" are also relative, representing only relative positions. In some usage scenarios, the top can be located below the bottom in the direction of gravity.

[0010] The pressure-sensitive protective sleeve in this application can be used on the legs, arms, waist, abdomen, etc. During product development or manufacturing, the main body, the first connecting piece, and the second connecting piece can be independent. In the first wearing state, the first and second connecting pieces are located on the left and right sides of the main body, respectively, and are detachably connected to the left and right ends opposite to the main body. At this time, the first and second connecting pieces and the main body are all oriented in the same direction. In the second wearing state, the first and second connecting pieces are located on the right and left sides of the main body, respectively, and are detachably connected to the right and left ends opposite to the main body. At this time, the first connecting piece and the main body are oriented in opposite directions, and the second connecting piece is also oriented in opposite directions. Therefore, the pressure-sensitive protective sleeve in this application has at least two different wearing states, each suitable for different stages of the disease. For example, one state is suitable for severe cases of elephantiasis, while the other state is suitable for cases where the condition has improved.

[0011] Regardless of the wearing state, when wearing it, first connect the first connecting piece and the second connecting piece to the appropriate positions at both ends of the main piece to assemble the three independent pieces into a whole. Then, place one side of this whole piece against the user's limbs, and then connect the first tension band and the second tension band to the outside of the second connecting piece and the first connecting piece respectively, thereby wrapping the legs, arms, waist, abdomen, etc.

[0012] Optionally, in one of the embodiments, at least one first tension band and at least one second tension band are spaced apart. After the first connecting piece and the second connecting piece are respectively connected to the main body piece, at least one first tension band and at least one second tension band are staggered. That is, the positions of the first tension band and the second tension band are respectively at the intervals of another connecting piece. This arrangement facilitates the pasting of the first tension band and the second tension band on the outside of another connecting piece. At this time, the pasting position can be located on the outside of the main body part of the connecting piece (non-tension band area), so the stability effect after pasting is also better.

[0013] In another embodiment, at least one first tension band and at least one second tension band may not be spaced apart. That is, after the first connecting piece and the second connecting piece are connected to the main body piece respectively, the positions of the first tension band and the second tension band are the tension bands of another connecting piece. With this arrangement, the two tension bands form a laminate.

[0014] The minimum number of the first and second tension bands can be 1, and their numbers can be equal, for example, both can be 2, 3, 4, etc., or they can be unequal, for example, 2 and 3 respectively. The number of the third and fourth tension bands can be equal, both can be 1, 2, 3, 4, etc.

[0015] Optionally, when the pressure-sensitive protective sleeve is in the first wearing state or the second wearing state, the difference between the upper and lower side lengths of the assembly formed by connecting the main body piece, the first connecting piece, and the second connecting piece is different. Because the size of the elephantiasis leg changes as treatment progresses—for example, in severe cases the leg is completely cylindrical, but as treatment progresses, the leg gradually shrinks from near the knee to near the ankle, similar to a normal person—the difference between the upper and lower side lengths of the assembly formed by connecting the main body piece, the first connecting piece, and the second connecting piece is different when the pressure-sensitive protective sleeve is in the first wearing state or the second wearing state. A smaller difference is suitable for patients with more severe elephantiasis, while a larger difference is suitable for patients who have undergone treatment for a period of time. The magnitude of this difference is relative; it is sufficient that the difference is different in both states.

[0016] Optionally, when the pressure-wearing sleeve is in the first wearing state, the side length of the upper end of the assembly formed by connecting the first connecting piece, the second connecting piece, and the main body piece is much greater than the side length of the lower end; when the pressure-wearing sleeve is in the second wearing state, the side length of the upper end of the assembly formed by connecting the main body piece, the first connecting piece, and the second connecting piece is close to the side length of the lower end, or even 0, or a difference of a few millimeters or centimeters. This can be achieved by setting the sum of the side lengths of the lower ends of the first connecting piece and the second connecting piece and the side length of the upper end of the main body piece to be equal to the sum of the side lengths of the upper ends of the first connecting piece and the second connecting piece and the side length of the lower end of the main body piece.

[0017] Optionally, when the pressure-wearing sleeve is in the second wearing state, the assembly formed by connecting the main body piece, the first connecting piece, and the second connecting piece is of equal width from top to bottom. When the pressure-wearing sleeve is in the first wearing state, the assembly formed by connecting the first connecting piece, the second connecting piece, and the main body piece gradually decreases in width from top to bottom.

[0018] Optionally, the main body piece also has an upper and lower end that are positioned opposite each other. The side length of the lower end of the main body piece is shorter than the side length of the upper end. A longer side length means a longer circumference around the limb. In actual use, the upper end with the longer side length can fit areas with a larger limb circumference, such as the lower leg near the knee, while the upper end can fit areas near the ankle. In this case, the first connecting piece also has an upper and lower end that are positioned opposite each other, and the second connecting piece also has an upper and lower end that are positioned opposite each other. The side length of the lower end of the first connecting piece can be shorter than the side length of the upper end of the first connecting piece, and the side length of the lower end of the second connecting piece can be shorter than the side length of the upper end of the second connecting piece.

[0019] More preferably, the width of the main body piece gradually decreases from the top to the bottom to accommodate the size of the entire lower leg, or arm, etc., and the width of the first connecting piece gradually decreases from the top to the bottom of the main body piece to correspond to the size of the main body piece.

[0020] Preferably, the lengths of all first tension bands extending beyond the main body of the first connecting piece are equal, the lengths of all second tension bands extending beyond the main body of the second connecting piece are equal, and the overall width is uniform from top to bottom. In one of the wearing states, the end of the first connecting piece used to connect with the main body piece and the end of the main body piece used to connect with the first connecting piece can be set parallel, and the same applies to the second connecting piece.

[0021] Optionally, the first tension bands can be of equal length, the second tension bands can be of equal length, or the first tension bands can be of unequal length, and the second tension bands can also be of unequal length.

[0022] Optionally, the upper end of the main body piece is set in an arc or a straight line, the lower end of the main body piece is set in an arc or a straight line, the upper end of the first connecting piece is set in an arc or a straight line, the lower end of the first connecting piece is set in an arc or a straight line, the upper end of the second connecting piece is set in an arc or a straight line, and the lower end of the second connecting piece is set in an arc or a straight line.

[0023] Optionally, the upper end can be set as an arc or a straight line, and the lower end can also be set as an arc or a straight line. Generally, both the upper and lower ends are set as straight lines, and the two lines are parallel to each other. In this case, the upper and lower ends of the two connecting pieces are also set as parallel straight lines. The first tension bands can be set parallel to each other, and the second tension bands can also be set parallel to each other.

[0024] Alternatively, to ensure that the two ends are flush after the sheath is worn, both the upper and lower ends are curved, with the curvature of the curves being consistent and the direction of the protrusion being consistent. Correspondingly, the upper and lower ends of the two connecting pieces are also set as curved lines with the same curvature and the same direction of protrusion. More preferably, the overall shape of the main body piece can be a fan ring, the main body of the first connecting piece and the second connecting piece can be a fan ring, and the shape of the first tension band and the second tension band can also be a fan ring.

[0025] Optionally, the first connecting piece is arranged in a straight line or an arc with one end of the main body piece, and the second connecting piece is also arranged in a straight line or an arc with one end of the main body piece. The second ends of both the first and second connecting pieces are arranged in a straight line or an arc. The ends of both the first and second connecting pieces used to connect to the main body piece (which can also be called the first ends) are both arranged in a straight line, and the opposite ends of the first and second connecting pieces (which can also be called the second ends) are also both arranged in a straight line. Alternatively, the first ends of both the first and second connecting pieces are arranged in an arc, which can be formed by a single arc with the same curvature or by a combination of multiple interconnected arcs.

[0026] Optionally, a first protrusion is provided at the first end of the first connecting piece to connect with the main body piece, and a second protrusion is provided at the first end of the second connecting piece to connect with the main body piece. The protrusion and the main body piece can be bonded. An adhesive surface is provided at the free end of the first tension band to bond with the outer side of the second connecting piece. An adhesive surface is provided at the free end of the second tension band to bond with the outer side of a connecting piece.

[0027] The adhesive surfaces of the first and second protruding pieces mentioned above can be achieved using Velcro, snap fasteners, or snap fasteners. The first and second protruding pieces can be directly sewn or glued to the connecting piece, and the adhesive surfaces can also be formed by directly sewing or gluing Velcro, snap fasteners, or snap fasteners to the connecting piece. As a complement, at least the areas of the main body piece used to mate with the first and second connecting pieces, or the outer areas of the first and second connecting pieces used to mate with the first or second tension band, are all designed to be adhesively attached using Velcro, snap fasteners, or snap fasteners.

[0028] Optionally, the first and second tension bands are made of elastic material. More preferably, one or more of the main body piece, the first connecting piece, and the second connecting piece are made of elastic material.

[0029] Tension bands are elastic, and different degrees of stretching will generate different levels of pressure on the limbs. In order to more intuitively show that the pressure has reached the target value, the pressure-wearing protective sleeve may also include an indicator, which is set on at least one first tension band or at least one second tension band to indicate whether the target tension has been reached.

[0030] The indicator can be in different forms. In one embodiment, the indicator includes a first indicator strip and a first fixed mark. The fixed end of the first indicator strip and the first fixed mark are both fixed to at least one first tension band or both are fixed to at least one second tension band. The indicator strip is provided with a mark, which is used to cooperate with the first fixed mark to indicate whether the target tension has been reached.

[0031] Optionally, the first fixed marker is an indicator line or a fixed ring. When the first fixed marker is a fixed ring, the free end of the first indicator bar is movable within the fixed ring.

[0032] In another embodiment, the indicator includes a second indicator strip and two second fixed marks, both of which are fixed to at least one first tension band or both are fixed to at least one second tension band. Each of the two second fixed marks is provided with a locking position for engaging the second indicator strip. Each end of the second indicator strip is provided with a limiting strip that cooperates with the locking position. When both ends of the second indicator strip are engaged with the locking positions on the two second fixed marks and the second indicator strip is straightened, the target tension is reached.

[0033] In summary, the pressure-wearing protective sleeve provided in this application has at least two wearing states, which can be applied to different stages of the disease. Attached Figure Description

Detailed Implementation

[0035] To make the above and other objects, features and advantages of this application more apparent and understandable, preferred embodiments are described below in detail with reference to the accompanying drawings. Example 1

[0036] Please refer to Figure 1 and Figure 2 This embodiment provides a pressure wearable cover 100, which has at least a first wearable state and a second wearable state. The pressure wearable cover is a three-piece type, namely a main body piece 1, a first connecting piece 2, and a second connecting piece 3. The first connecting piece and the second connecting piece are respectively used for detachable connection to the two ends opposite to the main body piece (the first end 13 and the second end 14, respectively); the first connecting piece extends at least one first tension band 21 from the end away from the connection with the main body piece (hereinafter referred to as the second end 23), and the second connecting piece extends at least one second tension band 31 from the end away from the connection with the main body piece (hereinafter referred to as the second end 33). At least one first tension band is used for detachable connection with the second connecting piece, and at least one second tension band is used for detachable connection with the first connecting piece; when the pressure wear sleeve is in the first wearing state, the first connecting piece, the second connecting piece, and the main body piece are all arranged in the same direction, with the first connecting piece and the second connecting piece located on the left and right sides of the main body piece, respectively; when the pressure wear sleeve is in the second wearing state, the first connecting piece and the second connecting piece are arranged in opposite directions to the main body piece, with the first connecting piece and the second connecting piece located on the right and left sides of the main body piece, respectively.

[0037] Optionally, the first connecting piece has a first end 22 and a second end 23 that are oppositely arranged on its inner and outer sides; the second connecting piece has a first end 32 and a second end 33 that are oppositely arranged on its outer side; wherein the first end of the first connecting piece and the first end of the second connecting piece are respectively used for detachable connection with the outer side of the main body piece; wherein the second end of the first connecting piece extends two first tension bands 21, and the second end of the second connecting piece extends three second tension bands 31, the first tension bands bypass the wearing part to detachably connect with the outer side of the second connecting piece, and the second tension bands bypass the wearing part to detachably connect with the outer side of the first connecting piece; the sheath after being worn forms a shape similar to a cylinder.

[0038] Here, the inner side is the side closer to the user's body, and the outer side is the side farther away from the user's body relative to the inner side. After connecting the first end of the first connecting piece and the first end of the second connecting piece to the appropriate positions on the outer side of the main body piece, the three independent pieces are assembled into a whole. The inner side of this whole piece is placed against the user's limb. At this time, the main body piece is located on the side closer to the user relative to the first and second connecting pieces. After passing all the first tension bands and second tension bands around the limb, they are connected to the outer side of another connecting piece. In this way, the main body piece, the first and second connecting pieces form a structure around the limb.

[0039] In this embodiment, the two first tension bands and the three second tension bands are spaced apart. After the first ends of the first connecting piece and the second connecting piece are connected to the outside respectively, the two first tension bands and the three second tension bands are staggered. That is, the positions of the first tension bands and the second tension bands are the intervals of the other connecting piece. This arrangement facilitates the pasting of the first tension bands and the second tension bands to the outside of the other connecting piece. At this time, the pasting position can be located on the outside of the main body of the connecting piece, so the stability effect after pasting is also better.

[0040] The first connecting piece includes a first tension band and a main body, and the second connecting piece includes a second tension band and a main body. The main bodies of both the first and second connecting pieces are identical in shape and size; for example, they can both be right-angled trapezoids or nearly right-angled trapezoids. Correspondingly, the shape of the main body piece can be an isosceles trapezoid. The main body piece also has a relatively parallel upper end 15 and a lower end 16. The side length L2 of the lower end of the main body piece is shorter than the side length L1 of the upper end. A longer side length means a longer circumference around the limb. In actual use, the longer upper end can fit areas with a larger limb circumference, such as the lower leg near the knee, while the upper end can fit areas near the ankle.

[0041] The first connecting piece also has an upper end 24 and a lower end 25 that are arranged opposite to each other and parallel to each other. The second connecting piece also has an upper end 34 and a lower end 35 that are arranged opposite to each other and parallel to each other. The side length L3 of the lower end of the first connecting piece can be less than the side length L4 of the upper end of the first connecting piece. The side length L5 of the lower end of the second connecting piece can be less than the side length L6 of the upper end of the second connecting piece.

[0042] There can be at least two ways to assemble the first connecting piece, the second connecting piece, and the main body piece, such as... Figure 2 In this design, the lower ends of the first and second connecting pieces are aligned with the upper ends of the main body piece, and vice versa. This design is applicable to conditions such as elephantiasis. In one form where the first ends of the first and second connecting pieces are respectively connected to the outer sides of the main body piece, the overall top and bottom sides are equal in length, i.e., L5 + L1 + L3 = L6 + L2 + L4. This can be achieved by setting the sum of the side lengths of the lower ends of the first and second connecting pieces and the upper end of the main body piece to equal the sum of the side lengths of the upper ends of the first and second connecting pieces and the lower end of the main body piece.

[0043] Preferably, the length L7 of all the first tension bands extending out of the second end of the first connecting piece is equal, the length of all the second tension bands extending out of the second connecting piece is equal, and the width is equal from top to bottom, with the width direction parallel to the upper and lower ends.

[0044] In another type of wear, such as Figure 1 In this design, the lower ends of the first connecting piece, the second connecting piece, and the main body piece can be set in the same direction, and the upper ends of the first connecting piece, the second connecting piece, and the main body piece can be set in the same direction. This design is suitable for situations such as after the improvement of elephantiasis symptoms, or when the circumference of the limb has changed.

[0045] Optionally, both the first and second ends of the main body piece can be trimmed to adjust the size. Figure 1 The direction of the dotted line indicated by the scissors can be used for cutting. Generally, the cutting direction is parallel to the edge line of the end, but it can be adjusted as needed. The cutting position can also be adjusted to suit patients of different body types or different patient positions.

[0046] In this embodiment, a plurality of mutually equidistant indicator lines are provided on the outer side of the main body piece to indicate the bonding position of the first end of the first connecting piece or the first end of the second connecting piece, so as to adapt to different usage requirements.

[0047] In this embodiment, a first protrusion 26 is provided at the first end of the first connecting piece to connect with the outer side of the main body piece, and a second protrusion 36 is provided at the first end of the second connecting piece to connect with the outer side of the main body piece. The inner side of the protrusion and the outer side of the main body piece can be bonded. An adhesive surface 27 is provided on the inner side of the free end of the first tension band to bond with the outer side of the second connecting piece. An adhesive surface 37 is provided on the inner side of the free end of the second tension band to bond with the outer side of the connecting piece.

[0048] The bonding surfaces of the first and second tabs mentioned above can be achieved using Velcro, snap fasteners, or snap fasteners. The first and second tabs can be directly sewn or glued to the connecting piece, and the bonding surfaces can also be formed by directly sewing or gluing Velcro, snap fasteners, or snap fasteners to the connecting piece.

[0049] Tension bands are elastic, and different degrees of stretching will generate different amounts of pressure on the limbs. To more intuitively show whether the target pressure value has been reached, the pressure-wearing protective sleeve may also include an indicator 6. The indicator is located on the first tension band or the second tension band to indicate whether the target tension has been reached. For ease of operation, the indicator 6 is located on the outside of the first tension band or the second tension band. Figure 1 and 2 The inside is shown, therefore the indicator is in Figure 1 and 2 (It is not actually visible in the image, so it is represented by a dashed line).

[0050] Indicators can take different forms, such as Figure 4 As shown, the indicator includes a first indicator strip 61 and a first fixed mark 62. The fixed end 611 of the first indicator strip and the first fixed mark 62 are both fixed on the first tension belt or both are fixed on the second tension belt. The indicator strip is provided with a mark, which is used to cooperate with the first fixed mark to indicate whether the target tension has been reached.

[0051] In this embodiment, the first fixed marker is an indicator line or a fixed ring. When the first fixed marker is a fixed ring, the free end of the first indicator bar is movable within the fixed ring.

[0052] The first indicator bar can be made of a non-stretchable material. Example 2

[0053] The difference from Example 1 is that, as Figure 3 , Figure 5 and Figure 6As shown, the indicator 6' in this embodiment includes a second indicator strip 61' and two second fixed marks 62''. Both second fixed marks are fixed on the first tension band or both are fixed on the second tension band. Both second fixed marks are provided with locking positions 621 for engaging the second indicator strip. The two ends of the second indicator strip are respectively provided with limiting strips 612 that cooperate with the locking positions. When both ends of the second indicator strip are engaged with the locking positions on the two second fixed marks and the second indicator strip is straightened, the target tension is reached.

[0054] Figure 3 Although the bonding surfaces of the first and second protrusions in the diagram are drawn and filled using a mesh surface, they are different from those in the diagram. Figure 1 and 2 The dots in the text are filled, but they represent the same thing: surfaces that can be bonded to the main body.

[0055] The extension direction of the limit bar 612 is different from that of the second indicator bar, and the two second fixed marks 62'' are positioned opposite each other.

[0056] The number of the first and second tension bands is 2 each.

[0057] The first ends of the first connecting piece and the second connecting piece are set as S-shaped curves.

[0058] The second indicator strip can be made of a non-stretchable material.

[0059] Those skilled in the art should understand that, in the disclosure of this application, the terms "upper," "lower," "front," "back," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on the application.

[0060] Although this application has been disclosed above by way of preferred embodiments, it is not intended to limit this application. Any person skilled in the art may make some modifications and refinements without departing from the spirit and scope of this application. Therefore, the scope of protection of this application shall be determined by the scope of protection claimed in the claims.
