Abstract
Description
[Technical field]
[0001] The present invention relates to a bandage wrapper that can wrap an elastic bandage with constant tension. [Background technology]
[0002] When the blood flow rate in the veins slows, it becomes easier to develop deep vein thrombosis (DVT, economy class syndrome), which causes blood clots. In particular, the lower limbs, where blood flows against gravity, are more susceptible to blood clots when anesthesia induces vascular dilation or when muscle relaxation reduces the pumping function. There is a risk that this blood clot may break off (become free) and become lodged in the pulmonary artery, causing pulmonary embolism.
[0003] As a method for preventing deep vein thrombosis, there are medical elastic stockings as disclosed in Patent Document 1. Medical elastic stockings have a much stronger compression force than normal stockings, and are designed to apply the strongest compression force at the ankles and weaker compression force toward the thighs in order to facilitate the flow of venous blood and lymph fluid toward the heart. However, medical elastic stockings are pre-made in sizes such as S, M, and L, and are not made to order, so many patients do not find the size suitable. In addition, medical elastic stockings are also used to prevent lymphedema (swelling), but pre-made stockings do not fit patients with severe lymphedema or deformed limbs. In addition, the compression force differs between deep vein thrombosis and edema, but the compression force of medical elastic stockings cannot be changed.
[0004] Therefore, a method of wrapping an elastic bandage around the limbs, as disclosed in Patent Document 2, was considered. Elastic bandages can be used for any shape of the lower limb, and have the characteristic that the pressure and range of compression can be adjusted according to the condition of the disease and the condition of the limb. Even if elastic stockings cannot be worn, the size does not fit, or they have been discontinued due to skin disorders, or stockings cannot be worn due to surgery or deformation of the lower limb, the limbs can be compressed using an elastic bandage. Compression with this elastic bandage is not only used to prevent deep vein thrombosis, but also to stop bleeding, control edema, treat varicose veins of the lower limbs, and treat lymphedema. Furthermore, elastic bandages are not only used for "compression," but also as bandages for "wound protection," as "fixation" to fix and rest fractures, dislocations, and sprains, and as "holding and support" to hold dressings and medicines that are prone to slip, and to support IV tubes and splints.
[0005] Elastic bandages must be wrapped around the affected area with a certain range of pressure. For example, to prevent deep vein thrombosis, the pressure must be between 26.7hPs and 40hPs (20mmHg and 30mmHg). Capillary pressure is 42.7hPs, so if the bandage is applied with a pressure higher than this, the capillaries will be blocked and blood will not flow to the skin tissue, so to prevent bedsores, the bandage must be kept below this value. Furthermore, when compressing the lower limbs, the pressure must be strongest at the ankles and weaker toward the thighs to facilitate the flow of venous blood and lymph fluid toward the heart. For example, the ratio of ankles to calves to thighs is 10:7:4.
[0006] Elastic bandages are mainly wrapped by nurses, but to wrap the affected area with a certain pressure, the elastic bandage must be pulled with a certain tension and wrapped a certain number of times. Wrapping the bandage with the required number of times is not particularly difficult, but pulling the elastic bandage with the required tension is very difficult and requires skill. Although various techniques are taught, the current situation is that the nurses rely on their sense, which leads to individual differences. In addition, when wrapping a wide elastic bandage, the elastic bandage side is pulled by placing it against the thumb and the ball of the foot, so the tension is not uniform across the width. Because of this variation in pressure caused by the elastic bandage, the elastic bandage must be removed and checked frequently to see if there are any abnormalities such as redness.
[0007] Patent Document 3 discloses an automatic bandager that adjusts the tension of the bandage by adjusting the rotational force of the bandage with finger pressure. Therefore, there are problems in that the finger pressure is not constant and that the tension of the bandage changes if the radius of the wrapped bandage changes.
[0008] In addition, even if the elastic bandage is pulled out from the bandage winding device with a certain tensile force, the part that has not yet been wrapped around the affected area may come loose. In particular, until the first wrap, the tip of bandage B must be held down with the other hand in order for the bandage to come off the affected area, so the bandage winding device 1C must be turned once with one hand, and the part that has not yet been wrapped around the affected area often comes loose.
[0009] Therefore, the inventors of the present application devised a bandage wrapper, as shown in Patent Document 4, in which the tension of the bandage does not change even if the radius of the bandage changes by pressing the outer plate with an appropriate amount of hand force as the bandage passes between the two plate surfaces of the bandage outlet.
[0010] In addition, the inventors of the present application have devised a bandage wrapper that allows even an unskilled person to apply a predetermined tension to the elastic bandage by changing the length of the narrow path through which the bandage is unwound, as shown in Patent Document 5. [Prior art documents] [Patent documents]
[0011] [Patent Document 1] JP 2014-188116 A [Patent Document 2] Special Publication No. 2015-526224 [Patent Document 3] JP 2001-137290 A [Patent Document 4] JP 2018-143265 A [Patent Document 5] JP 2019-50989 A Summary of the Invention [Problem to be solved by the invention]
[0012] The bandage winding device of Patent Document 4 has an adjustment screw for adjusting the gap between the two plate surfaces through which the bandage passes, but as shown in FIG. 4 of Patent Document 4, the support 33 on which the adjustment screw is held has two guides 33c that are simply fitted into the guide holes 21d of the case 21, and the support 33 is not held or fixed to the case 21. Therefore, unless the support 33 is pressed by the thumb or the ball of the foot, the gap between the two plate surfaces through which the bandage passes is not maintained at a specified dimension. In other words, Patent Document 4 has a disadvantage that, even if the adjustment screw is attached, the bandage cannot be pulled with a specified tension unless it is pressed by the thumb or the ball of the foot. For example, when wrapping multiple bandages around a lower limb, the bandage is switched between the right hand and the left hand, and at this time, the pressure on the support 33 of Patent Document 4 is interrupted, which may cause the bandage to loosen.
[0013] The bandage winding device of Patent Document 5 has a double structure of an inner case and an outer case to provide a narrow and long path for the bandage to be unwound. This has the disadvantage of making the outer diameter larger. For female nurses with small hands, a larger outer diameter makes it difficult to wind a bandage, so it is preferable to have a device that is as small as possible. SUMMARY OF THE PRESENT EMBODIMENT An object of the present invention is to provide a small-sized bandage winding device that can pull an elastic bandage with a predetermined tension without the need for manual pressure. [Means for solving the problem]
[0014] In order to solve the above problems, one embodiment of the bandage winding device of the present invention is characterized in that a gap is provided at the bandage withdrawal opening of a cylindrical bandage storage section that stores a bandage, which applies resistance to the withdrawal of the bandage, and the gap is formed by a passage wall through which the bandage passes and an indenter fixed opposite the passage wall.
[0015] The bandage wrapper of the present invention applies tension to the bandage by the resistance of the gap, so there is no need for multiple cases, making it compact. Also, since the gap is formed by the passage wall and the indenter fixed to it, the gap remains constant, eliminating the need for manual pressure and allowing for a stable tension to be maintained, making it easy to wrap the bandage.
[0016] In the bandage winding device of the present invention, it is preferable that the indenter is rotatably fixed and has an operating part for rotating the indenter and adjusting the gap. With this configuration, by rotating the indenter with the pressure operating part, the gap with the opposing passage wall can be changed and the tension of the bandage can be adjusted.
[0017] In the bandage winding device of the present invention, the operating section is preferably provided on a side surface of the bandage container section. With this configuration, the operating section can be easily operated with a finger even during the bandage winding operation, and the tension of the bandage can be easily adjusted.
[0018] In the bandage winding device of the present invention, it is preferable to provide a protrusion along the side of the bandage storage section. With this configuration, the protrusion can be placed on the palm of the hand when rotating, making it easy to switch between left and right hands. This configuration is also very easy to handle for nurses with small hands.
[0019] In the bandage winding device of the present invention, it is preferable that a roller is provided on the outside of the bandage storage section, and the roller is deformable. The roller provided on the outside of the bandage storage section can reduce loosening of the bandage unwound from the bandage winding device, and such a configuration of the roller allows the roller to follow the curvature of the human body, making the winding operation easier.

[0021] The following describes the mode for carrying out the present invention with reference to the embodiments and drawings, but the embodiments shown below are not intended to limit the present invention to those described herein, and the present invention is equally applicable to those in which various modifications are made without departing from the technical ideas set forth in the claims. Note that in each drawing used for explanation in this specification, each component is shown at a different scale so that each component is large enough to be recognized on the drawing, and is not necessarily shown in proportion to the actual dimensions.
[0022] The background of the invention of the bandage wrapper 1 of the embodiment will be described with reference to FIG. 1. The inventor conducted an experiment on the tension of the elastic bandage EB and the compression pressure of the elastic bandage EB. As a result, as shown in FIG. 1, it was found that there is a correlation between the tension of the elastic bandage EB and the compression pressure. For example, if an approximation formula is obtained from the experimental data by the least squares method, it is possible to obtain the tension of the elastic bandage EB to obtain the desired compression pressure. Conversely, it is also possible to obtain the compression pressure from the tension. Based on the results of this experiment, the inventor thought that if he invented a bandage wrapper 1 that adjusts the tension, it would be possible to wrap the elastic bandage EB at a constant desired compression pressure.
[0023] The compression pressure suitable for compression therapy is 26.7hPs to 40hPs (20 to 30mmHg), so the tension of the elastic bandage EB suitable for compression therapy is about 6N to about 13N as shown in FIG. 1. The inventors also conducted tensile tests on the tension and elongation of the elastic bandage EB. As a result, it was found that the bandage stretches rapidly when it exceeds 20N, but stretches in proportion to the tension at about 6N to about 13N, which is suitable for compression therapy. Based on these results, the bandage wrapper 1 was invented.
[0024] [Embodiment] 2 to 7, the configuration of the bandage wrapper 1 of the embodiment capable of wrapping the elastic bandage EB at a constant desired compression pressure will be described. Note that Fig. 5A is a see-through view of the right side of the bandage wrapper in order to show the main parts of the present invention. The bandage wrapper 1 comprises a bandage container 2, a first roller R1, and a second roller R2.
[0025] [Bandage storage section] The bandage storage section 2 stores the elastic bandage EB and has an adjustment function for changing the resistance with which the elastic bandage EB is unwound in order to adjust the tension when the elastic bandage EB is wrapped around it. Specifically, the bandage storage section 2 is made up of a case 3, a bottom cover 4, a first roller top attachment 5, a second roller top attachment 6, a top cover 7, and a gap adjustment section 8.
[0026] Case 3 is made of injection-molded synthetic resin or extruded aluminum material, and is cylindrical in shape with a C-shaped cross section (with the opening facing downward) as shown in Figures 4 and 7. Bosses 31 are formed at both ends of the C shape and at three points in the center, and female threads 32 (see 32 in Figure 6) are cut at both ends of each boss 31. Furthermore, as shown in Figures 2B and 7, central boss 31 protrudes outward along the cylindrical side surface of case 3, forming a protrusion in bandage storage section 2.
[0027] 6A, the bottom cover 4 covers the bottom portion, which is one end side of the case 3, and houses part of the gap adjustment part 8 described below. Specifically, the bottom cover 4 is composed of an inner cover 41, an outer cover 42, a first roller bottom mounting fixture 43, and a second roller bottom mounting fixture 44.
[0028] The synthetic resin inner lid 41 and outer lid 42 are made of substantially the same shape, consisting of a substantially circular portion that closes the opening of the case 3 and a portion that protrudes from the circular portion for mounting the first roller R1 and the second roller R2 (portions that form the first roller bottom mounting fixture 43 and the second roller bottom mounting fixture 44, which will be described next). The inner lid 41 and the outer lid 42 form a space on the opposing side, and the bottom lid 4 is configured to accommodate a part of the gap adjustment part 8 within this formed space.
[0029] The first roller bottom mounting fixture 43 is attached to one end of the first roller R1, and the second roller bottom mounting fixture 44 is attached to one end of the second roller R2. The first roller bottom mounting fixture 43 extends integrally from each of the inner lid 41 and the outer lid 42, and the portion extending from the inner lid 41 and the portion extending from the outer lid 42 overlap to form one first roller bottom mounting fixture 43. Similarly, the second roller bottom mounting fixture 44 extends integrally from each of the inner lid 41 and the outer lid 42, and the portion extending from the inner lid 41 and the portion extending from the outer lid 42 overlap to form the second roller bottom mounting fixture 44. 5A and 6B, the bottom cover 4 is screwed onto the three bosses 31 of the case 3 with three second bolts B2 to close the bottom portion, which is one end side of the case 3.
[0030] Next, the other end side of the case 3 will be described. As shown in FIG. 5B, the first roller-on mounting fixture 5 and the second roller-on mounting fixture 6 are parts for mounting the first roller R1 and the second roller R2, and are shaped to protrude from the case 3 and are made of synthetic resin. As shown in FIG. 5B and FIG. 6B, the first roller-on mounting fixture 5 and the second roller-on mounting fixture 6 are screwed to the boss 31 at the end of the case 3 by the third bolt B3. The first roller-on mounting fixture 5 faces the first roller bottom mounting fixture 43 on the opposite side via the first roller R1. The second roller-on mounting fixture 6 faces the second roller bottom mounting fixture 44 on the opposite side via the second roller R2.
[0031] As shown in Fig. 6A, the top cover 7 covers the upper opening at the other end side of the case 3. The top cover 7 is also made of synthetic resin. As shown in Figs. 5B and 6B, the top cover 7 is screwed to the top of the central boss 31 of the case 3 with a third bolt to cover the top of the case 3.
[0032] The top cover 7 is provided with two protruding screw caps 71 to hide the third bolts B3 that screw together the first roller-mounted attachment 5 and the second roller-mounted attachment 6. The screw caps 71 fit into the recesses 51, 61 into which the heads of the third bolts B3 of the first roller-mounted attachment 5 and the second roller-mounted attachment 6 fit. With the configuration of the bandage storage section 2 as in this embodiment, the opening side of the case 3 is prone to opening due to bending of the case 3, but the screw caps 71 fitting into the recesses 51, 61 can prevent the case 3 from opening.
[0033] The gap adjustment unit 8 constitutes an adjustment function for changing the resistance to which the elastic bandage EB is unwound. Specifically, the gap adjustment unit 8 is composed of a passage wall 81, a presser 82, an adjustment knob 83, and a transmission gear 84.
[0034] The passage wall 81 is provided along the opening of the case 3 and serves as a passage through which the elastic bandage EB unwound from the case 3 passes, and extends from one boss 31 of the case 3 as shown in Fig. 7. More specifically, as shown in Fig. 7, this passage wall 81 is composed of a horizontal passage wall that forms the passage end, an oblique passage wall that is connected to the horizontal passage wall, and a vertical passage wall that is connected to the oblique passage wall and reaches the boss 31 of the case 3.
[0035] The indenter 82 applies resistance when the elastic bandage EB is unwound by bringing a tip 82a of the indenter 82 into contact with the elastic bandage EB passing over the passage wall 81. Specifically, the indenter 82 is provided along the opening of the case 3, similar to the passage wall 81, and has a cross section with rounded corners (oval track) as shown in FIG. 7. As shown in FIG. 7, the indenter 82 is fixed rotatably relative to the passage wall 81. A gap S between the tip 82a of the indenter 82 and the passage wall 81 becomes the passage through which the elastic bandage EB is unwound. This gap S provided at the bandage withdrawal opening applies resistance to the elastic bandage EB.
[0036] The indenter 82 has shafts formed on both ends, one of which is supported by the second roller upper fixture 6 (see Figs. 4 and 5B) and the other by the outer cover 42 of the bottom cover 4 (see Fig. 6A). This configuration allows the indenter 82 to rotate.
[0037] Rotation of the indenter 82 changes the gap S formed between the tip 82a of the indenter 82 and the passage wall 81. The change in the gap S changes the resistance to the unwinding of the elastic bandage EB. In other words, the rotation of the indenter 82 gradually widens or narrows the gap S, and the resistance changes accordingly.
[0038] The shape of the tip 82a of the indenter 82 is preferably an arc shape as shown in Fig. 7. The inventors initially designed the shape of the tip 82a of the indenter 82 to be a rectangle with rounded corners, which is different from the shape of this embodiment. However, even if the indenter 82 with rounded corners was rotated, it was difficult to adjust the resistance applied to the elastic bandage EB due to the straight line portion of the tip 82a. On the other hand, when the tip 82a was shaped as in this embodiment, the resistance applied to the elastic bandage EB could be changed linearly by rotating the indenter 82, and the resistance could be easily and accurately adjusted.
[0039] The adjustment knob 83 is operated by the user when rotating the indenter 82 to change the gap S. The adjustment knob 83 is disk-shaped, and its side surface 83a is knurled to make it easy to rotate with a finger. The adjustment knob 83 is disposed in the space formed by the inner cover 41 and the outer cover 42 of the bottom cover 4, and a part of the side surface 83a of the adjustment knob 83 protrudes from the first roller bottom mounting tool 43 side of the bottom cover 4, as shown in FIG. 5A. The protrusion of the adjustment knob 83 is provided on the side surface of the bandage storage section 2, and constitutes an operating section that rotates the indenter 82 to adjust the gap S.
[0040] The adjustment knob 83 includes an adjustment knob gear 831, and is journalled between the inner lid 41 and the outer lid 42 within the bottom lid 4. The adjustment knob 83, which is an operating part, can be rotated by the user's finger.
[0041] Additionally, within the bottom cover 4, the transmission gear 84 and an indenter gear 821, which rotates integrally with the indenter 82, are also journaled by the inner cover 41 and the outer cover 42. For this reason, rotation of the adjustment knob 83 by the user results in rotation of the adjustment knob gear 831, as shown in Figures 5A and 6A, and is transmitted to the rotation of the indenter gear 821 of the indenter 82 via the transmission gear 84.
[0042] In this way, the bandage storage section 2 has a passage wall 81 through which the elastic bandage EB passes and a facing indenter 82 fixed thereto, forming a gap S. Therefore, a constant gap S is maintained, and a stable tension can be maintained at all times, compared to when the gap S is formed by pressing with a hand, making it easier to wrap the elastic bandage EB.
[0043] In addition, when the adjustment knob 83 of the bandage storage section 2 is rotated, the fixed presser 82 rotates and the gap S changes, the resistance to the unwinding of the elastic bandage EB changes, and the tension with which the elastic bandage EB is wrapped changes.
[0044] The adjustment knob 83 is located on the side of the bandage container 2 and at the end of the bandage container 2. This allows the user to easily operate the adjustment knob 83 with their fingers while still holding the bandage winding device 1. This makes it easy to change the pressure, for example, when wrapping the elastic bandage EB around the lower leg, so that the pressure is strongest at the ankle and weaker toward the thigh. Furthermore, the gap S is maintained even if the user removes their finger from the adjustment knob 83, so there is no need to constantly operate the adjustment knob 83.
[0045] In addition, as shown in Figs. 3A and 6A, the adjustment knob 83 of this embodiment is slidable in the direction of the rotation axis, and the shaft 833 of the adjustment knob 83 is normally protruded from the outer lid 42 by the coil spring 832. At this time, an inclined convex portion (not shown) provided on the flat surface of the adjustment knob gear 831 engages with an inclined convex portion (not shown) provided on the inside of the outer lid 42, and the adjustment knob 83 can be rotated only in one direction (the direction in which the gap S by the indenter 82 widens). Therefore, when the bandage winding device 1 is in use, the adjustment knob 83 can be rotated only in the direction that weakens the tension of the elastic bandage EB. On the other hand, when the shaft 833 is pressed by the user's finger, the engagement between the inclined convex portion (not shown) provided on the flat surface of the adjustment knob gear 831 and the inclined convex portion (not shown) provided on the inside of the outer lid 42 is released, and the adjustment knob 83 can also be rotated in the other direction (the direction in which the gap S by the indenter 82 narrows). Therefore, for example, when rewinding the elastic bandage EB or when returning the indenter 82 to its original position, the shaft 833 is pressed by the user.
[0046] [1st roller / 2nd roller] The first roller R1 and the second roller R2 come into close contact with the body and support the bandage storage section 2 when the elastic bandage EB is wrapped with the bandage wrapping device 1. The first roller R1 also functions as a roller for pressing the elastic bandage EB that has been unwound outside the bandage storage section 2 toward the human body.
[0047] In Fig. 4, the first roller R1 is disposed in the opposite direction to the direction in which the elastic bandage EB is unwound from the bandage container 2, and the second roller R2 is disposed in the direction in which the elastic bandage EB is unwound. The first roller R1 and the second roller R2 are the same part. Therefore, their configurations will be described using the cross-sectional portion of the first roller R1 in Fig. 6B.
[0048] As shown in Fig. 6B, the first roller R1 is composed of a core R11 divided into seven pieces, bearings R12 at both ends, and a skin R13 that covers the core R11 and the bearings R12. The core R11 is made of synthetic resin (e.g., ABS resin), and the skin R23 is a pipe made of soft synthetic resin (e.g., silicone). In the prototype shown in Figs. 2 to 4, for example, as can be seen from Fig. 2C, the skin R13 of the first roller R1 is opaque, and the skin R23 of the second roller R2 is translucent.
[0049] 6B, at one end of the first roller R1, the first bolt B1 screwed into the first roller top mounting fixture 5 fits into the bearing R12 and the core R11 on the one end side. At the other end of the first roller R1, the first bolt B1 screwed into the first roller bottom mounting fixture 43 fits into the bearing R12 and the core R11 on the other end side.
[0050] With this configuration, the first roller R1 is rotatably supported on the bandage container 2 between the first roller top mounting fixture 5 and the first roller bottom mounting fixture 43. The second roller R2 is also rotatably supported on the bandage container 2 between the second roller top mounting fixture 6 and the second roller bottom mounting fixture 44.
[0051] In addition, the first roller R1 is deformable along the rotation axis direction because the core R11 is divided into multiple parts and the skin R13 is soft. Therefore, the first roller R1 can easily follow the curvature of the human body. The same is true for the second roller R2.
[0052] [How to use] Next, a method of using the bandage winding device 1 of this embodiment will be described. First, as shown in Fig. 4, with the top cover 7 removed, the elastic bandage EB is housed in the case 3 in a counterclockwise direction. At this time, the elastic bandage EB is passed through the gap S between the tip 82a of the indenter 82 and the passage wall 81. Then, the top cover 7 is screwed to the case 3 with the third bolt B3. At this time, the elastic bandage EB that has passed through the gap S is folded back at the end of the passage wall 81 as shown in Fig. 4, and is pulled out toward the first roller R1 (not the second roller R2).
[0053] 8A and 8B, with the first roller R1 and the second roller R2 in close contact with the body, the bandage winding device 1 is moved with the second roller R2 at the front, and the elastic bandage EB is wound around the body. At this time, the first roller R1 and the second roller R2 are in close contact with the curved surface of the body due to their flexure, so the work of winding the elastic bandage EB is stable, the tension is uniform, and the first roller R1 presses the elastic bandage EB evenly.
[0054] In this wrapping operation, the adjustment knob 83 is rotated according to the type of elastic bandage EB and the part to be wrapped so that the compression pressure of the elastic bandage EB becomes a predetermined value. Moreover, the adjustment knob 83 can be rotated with the fingers of the hand holding the bandage winding device 1 even during the wrapping operation.
[0055] In addition, when the purpose of use of the elastic bandage EB is different, for example, when it is used to protect a wound or fix a sprained part, the compression pressure may be changed. In this case, the adjustment knob 83 is operated to obtain the tension that obtains the desired compression pressure. In this way, the tension of the bandage winding device 1 can be adjusted according to the situation, so that the desired compression pressure can be obtained. Note that, although the example using the elastic bandage EB has been described in this embodiment, it is not limited to the elastic bandage EB, and the bandage winding device 1 can be used as a general bandage.
[0056] 7, the central boss 31 of the case 3 is a protrusion that protrudes along the cylindrical side surface of the bandage storage section 2. This protrusion can be used to hook a finger (see FIG. 8A) or to prevent the palm of the hand from slipping, making wrapping easier. In particular, when wrapping the bandage winding device 1, the bandage winding device 1 is switched between the left and right hands, and this makes it easier to switch hands.
[0057] In the above embodiment, the first roller R1 and the second roller R2 have the same diameter, but they may have different diameters. By changing the diameter of the rollers, it is possible to accommodate various diameters of the affected area. In addition, by making the position of the rollers changeable, it is possible to accommodate various diameters of the affected area.
[0058] In addition, the direction in which the elastic bandage EB is stored in the case 3 and the route in which the elastic bandage EB is unwound from the gap S are not limited to the above-mentioned method, and other methods may be used. In this embodiment, the elastic bandage EB is moved with the second roller R2 side at the front. However, for example, the elastic bandage EB that is folded back at the end of the passage wall 81 and pulled out to the first roller R1 side can be further folded back to the second roller R2 side through the upper side of the first roller R1, so that the elastic bandage EB is moved with the first roller R1 side at the front.
