Description

  The present invention relates to a bandage wrapping tool that can be wound with a constant tension of an elastic bandage.

  In order for the blood in the limbs to circulate at normal speed, it is necessary to help relax the muscles that act as pumps. There is a valve in the vein, and when the muscle contracts, the deep vein is compressed and blood is sent to the central side. As the muscle relaxes, the blood on the peripheral side is sucked up. This is the role of the muscle pump. When the blood flow velocity of the vein becomes slow, it becomes easy to develop deep vein thrombosis (DVT, economy class syndrome) in which a thrombus occurs. In particular, the lower limbs in the direction of blood flow against gravity tend to develop thrombus. There is a risk of pulmonary thromboembolism, where the thrombus peels (free) and becomes clogged with the pulmonary artery.

  There are various factors that slow the flow of veins. In anesthetized patients, vascular dilation is induced by the effect of anesthesia and the blood flow velocity of the veins is slowed down. Exercise continuously with the same posture, such as long-term bed rest, lower limb surgery and fractures, elderly and disabled people who have difficulty walking, long rides on vehicles, evacuation in disasters, and the industry that is standing fast. If not, the muscle pump is insufficient and the blood flow rate is slowed down.

  As a method for preventing deep vein thrombosis, there is a method of using an anticoagulant, but there is a risk that blood is difficult to stop when bleeding occurs. As a method without this risk, there is a compression method. By compressing the limbs, the blood vessels become slightly narrower and the blood flow speed increases. As this compression method, as disclosed in Patent Document 1, intermittent pneumatic compression method (pneumatic pump, IPC) that compresses the lower limbs by intermittently sending air from the device to the wearing device wound around the lower limbs. ) However, because intermittent pneumatic compression works as a pump, or in the presence of deep venous thrombosis, if there is a suspected history of deep venous thrombosis, the risk of removing thrombosis on the vein wall and causing pulmonary embolism As a general rule, do not use it. Also, intermittent pneumatic compression cannot be used during orthopedic traction.

  As another compression method, there is a medical elastic stocking as disclosed in Patent Document 2. Since the compression force of the commercially available compression stockings is 20 hPs (15 mmHg) or less, the medical use has a stronger compression force than the commercially available one. Also, for medical use, in order to facilitate the flow of venous blood and lymph toward the heart, the pressure on the ankle is the strongest and the pressure is made weaker toward the thigh. However, the elastic stockings for medical use are off-the-shelf dimensions such as S, M, and L dimensions, and are not made to order, so there are many patients whose dimensions do not match. Medical elastic stockings are also used to prevent lymphedema (swelling), but they are not suitable for patients with large lymphedema or patients with deformed limbs. In addition, although the compression force differs between deep vein thrombosis and edema, the medical elastic stockings cannot change the compression force.

  Then, the method of winding an elastic bandage around limbs as disclosed in Patent Document 3 was considered. The elastic bandage can be used in any lower limb shape, and is characterized by the ability to adjust the compression pressure and range according to the medical condition and limb condition. Even if the stockings cannot be worn due to surgery or deformation of the lower limbs that cannot be worn with the elastic stockings, do not fit in size, or have been interrupted due to skin disorders, etc., the extremities can be compressed using the elastic bandage. This elastic bandage compression is used not only to prevent deep vein thrombosis but also to control hemostasis and edema, to treat varicose veins and to treat lymphedema. Furthermore, elastic bandages are not only “compressed” but also elastic bandages as “wound protection”, “fixing”, fracture and dislocation, fixation and rest of sprains, and dressings and drugs that are easily displaced as “holding / supporting” It is also used for supporting drip tubes, drip tubes and cines.

  The elastic bandage must be wound around the affected area with a predetermined range of pressure. For example, for prevention of deep vein thrombosis, the pressure should be 26.7 hPs to 40 hPs (20 mmHg to 30 mmHg). Capillary blood pressure is 42.7hPs, so if you apply more pressure with an elastic bandage, the capillaries will be blocked and blood will not pass through the skin tissue. Must be. Furthermore, in the compression to the lower limbs, in order to facilitate the flow of venous blood and lymph toward the heart, the ankle must be wound with the highest pressure and the pressure toward the thigh being weakened. For example, the ratio is 10: 7: 4 for ankle: calf: thigh.

  The elastic bandage is mainly wound by a nurse, but in order to wrap around the affected area with a predetermined pressure, the elastic bandage must be pulled with a predetermined tension and a predetermined number of turns. Although it is not so difficult to obtain a predetermined number of turns, it is very difficult to pull the elastic bandage with a predetermined tension, and skill is required. Although teaching various techniques, the current situation is that it depends on the feelings of nurses, resulting in individual differences. Also, when winding a wide elastic bandage, the elastic bandage side is pulled against the thumb (thumb) and the thumb ball, so that the tension is not uniform in the width direction. As described above, since the pressure due to the elastic bandage varies, it is necessary to frequently check whether there is an abnormality such as redness by releasing the elastic bandage.

  Patent Document 4 discloses a bandage in which a mark representing the degree of expansion is formed, but this problem cannot be solved unless the bandage is used. In addition, the commercialization of this bandage cannot be confirmed.

  Moreover, although the automatic bandage which winds a bandage is disclosed by patent document 5, it cannot be confirmed that such an automatic bandage is commercially available. Difficult to understand. Although Patent Document 5 seems to adjust the tension of the bandage by adjusting the rotation of the bandage by pressing the finger, it does not directly adjust the tension of the bandage, but with a finger at a place different from the bandage. It has a configuration to suppress.

  In order to wind the elastic bandage so that the compression pressure is 26.7 hPs to 40 hPs, a tension adjustment function is required so that the tension of the elastic bandage used is 26.7 hPs to 40 hPs. However, since Patent Document 4 and Patent Document 5 do not have this tension adjustment function, it is difficult to obtain a predetermined compression pressure.

  Moreover, even if the elastic bandage is pulled out from the bandage wrapping tool with a certain tensile force, there is a possibility that the portion that has not yet been wound around the affected area will loosen. In particular, until the first roll, if the tip of the bandage B is not pressed with the other hand, the bandage will come off the affected area, so the bandage wrapping tool 1C has to go around with one hand and is still wrapped around the affected area. Often there are no loose parts.

  Therefore, an object of the present invention is to provide a bandage wrapping device that has a tension adjusting function and can wrap a bandage around an affected area so that the tension of the bandage to be used becomes a predetermined compression pressure. Moreover, it aims at providing the bandage winding tool which reduces that the bandage drawn out from the bandage winding tool loosens.

  As a study for solving the above problems, the present inventor conducted experiments on the tension of the elastic bandage and the compression pressure by the elastic bandage. As a result, as shown in FIG. 1, it was found that there is a correlation between the tension of the elastic bandage and the compression pressure. The inventor also conducted a tensile test on the tension and elongation of the elastic bandage. As a result, it was found that in the range of the compression pressure of 26.7 hPs to 40 hPs (20 to 30 mmHg) that is considered to be suitable for the compression therapy, the elongation increases in proportion to the tension. The present inventor also conducted a tensile cycle test. As a result, the relationship between tension and elongation of the elastic bandage did not change even when the tension was repeated.

  From these results, the present inventor has conceived of realizing an optimal compression pressure by appropriately adjusting the tension for pulling out the bandage including the elastic bandage. Therefore, in order to solve the above-described problem, a bandage winding device according to one aspect of the present invention includes a bandage accommodating part that accommodates a bandage, and a tension adjusting part that adjusts a tension for pulling out the bandage from the bandage accommodating part. It is characterized by that.

  By providing the tension adjusting section for adjusting the tension, an optimal compression pressure can be realized as shown in FIG. 1, and the bandage so that the tension of the bandage to be used becomes a predetermined compression pressure even if it is not an expert. Can be wrapped around the affected area.

In the bandage winding device of the present invention, it is preferable that the tension adjusting unit is provided in a pull-out path for pulling out the bandage from the bandage accommodating unit, and adjusting the resistance due to frictional force.
By providing resistance due to frictional force in the pull-out path, a compact and inexpensive tension adjusting unit can be obtained.

In the bandage wrapping device of the present invention, the bandage accommodating portion includes an inner case that accommodates the bandage and has a first outlet, and an outer case that accommodates the inner case and has a second outlet. The bandage is accommodated so that it comes out of the first outlet, passes through the gap between the inner case and the outer case, and is exposed from the second outlet, and the resistance due to the frictional force in the tension adjusting portion is , When the bandage is pulled out, the resistance due to the frictional force applied in the path between the first outlet and the second outlet, and the adjustment in the tension adjusting portion is the first outlet by the rotation of the inner case The adjustment is preferably performed by changing the length of the path between the second outlets.
By using a double case and utilizing friction between cases, the resistance can be adjusted with a more compact configuration.

  In the bandage wrapping device of the present invention, it is preferable that the resistance applying mechanism has a gap between the first outlet and the second outlet that is gradually narrowed toward the first outlet.

With such a configuration, the longer the length of the path between the first outlet and the second outlet, the narrower the gap and the greater the frictional force. Therefore, a large change in resistance can be obtained with a short bandage pull-out path.
Moreover, in the bandage winding tool of this invention, it is preferable that the 1st roller is provided in the vicinity of the said 2nd exit in the said outer case.
Since the bandage can be wound while being pressed against the affected area and rolled, it can be wound while maintaining tension.
Moreover, in the bandage winding tool of this invention, it is preferable that the said resistance provision mechanism provides a 2nd roller in the position on the opposite side to the said 1st roller of the said drawer opening.

  The inclination of the first roller can be stabilized by winding the second roller in contact with the affected part. In addition, since the bandage that is stretched and fed out from the first holding roller with a predetermined tension is sandwiched between the second roller and the affected part, the stretched state can be maintained and the predetermined tension can be maintained.

  DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments for carrying out the present invention will be described with reference to the embodiments and drawings. However, the embodiments shown below are not intended to limit the present invention to those described herein, and The invention can be equally applied to various modifications without departing from the technical idea shown in the claims. In addition, in each drawing used for the description in this specification, in order to make each member a size that can be recognized on the drawing, each member is displayed with a different scale, and is not necessarily actual. It is not displayed in proportion to the dimensions.

[Preliminary experiment]
First, the background of inventing the bandage winding tool 1 will be described with reference to FIG. Since the present inventor has so far unknown the relationship between the tension of the elastic bandage EB and the compression pressure by the elastic bandage EB, in order to clarify this point, the tension of the elastic bandage EB and the compression by the elastic bandage EB A pressure experiment was conducted.

  Specifically, a pressure measuring device (a device that measures the pressure of the air that is pushed out when the sponge set in the sensor part is pressed) is fixed on a resin with the same hardness as the human body. And experimented. 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. From this, for example, if an approximate expression is obtained from the experimental data by the least square method, the tension of the elastic bandage EB for obtaining a desired compression pressure can be obtained. Conversely, the compression pressure can be obtained from the tension. From this experimental result, the present inventor considered that if the bandage winding tool 1 for adjusting the tension is invented, the elastic bandage EB can be wound with a desired compression pressure.

  The compression pressure considered to be suitable for the compression therapy is 26.7 hPs to 40 hPs (20 to 30 mmHg) indicated by a frame in FIG. Accordingly, the tension of the elastic bandage EB suitable for compression therapy is about 6N to about 13N from FIG.

  The inventor also performed a tensile test on the tension and elongation of the elastic bandage EB. As a result, it has been found that it grows abruptly when it exceeds 20 N, but stretches in proportion to the tension at about 6 N to about 13 N suitable for compression therapy.

The inventors also conducted a tensile cycle test. As a result, the relationship between tension and elongation of the elastic bandage EB did not change even when the tension was repeated. From this experimental result, it was found that the elastic bandage EB can be reused with the bandage winding tool 1.
From the experimental results as described above, the present inventor invented the bandage winding tool.

[Embodiment]
Next, the configuration of the bandage wrapping tool 1 according to the embodiment, in which the elastic bandage EB can be wound uniformly with a desired compression pressure, will be described with reference to FIGS. The bandage winding device 1 according to the present embodiment includes a bandage accommodating part 2 that accommodates the elastic bandage EB, and a tension adjusting part that adjusts the tension for pulling out the elastic bandage EB from the bandage accommodating part 2. More specifically, the bandage winding tool 1 includes a bandage accommodating portion 2 that also serves as a tension adjusting portion, a first roller R1, a second roller R2, and a nut N.

  The bandage accommodating portion 2 includes an inner case 3, an inner lid 4, an outer case 5, an outer lid 6, a coil spring S, and an E-type retaining ring E. FIG. 6 is a perspective view of the inner lid 4, the outer lid 6, and the nut N in order to describe the main part of the present invention.

  As shown in FIG. 3 and FIG. 5 (A), the inner case 3 is a cup-shaped synthetic resin formed by injection molding, and includes a circular bottom wall 31 and a cylindrical peripheral wall 32, and an elastic bandage EB is provided inside. Accommodate. The peripheral wall 32 is provided with a slit-like first outlet 33 through which the elastic bandage EB is pulled out. As shown in FIG. 3, four recesses 34 for engaging with the inner lid 4 are cut out on the opening side of the peripheral wall 32. Further, as shown in FIG. 5A, a metal connecting shaft 35 for joining to the outer case 2 is fixed to the center of the bottom wall 31 of the inner case 3 by an insert toward the outside. The connecting shaft 35 is formed with a groove 351 into which an E-type retaining ring (commonly called C-ring) E is fitted.

  As shown in FIG. 3, the inner lid 4 is a lid that closes the inner case 3, and is a synthetic resin in the shape of a top hat having a low height. The inner lid 4 includes a petri-shaped (shallow cup-shaped) fitting portion 41 that fits into the peripheral wall 32 of the inner case 3 and a disk-shaped contact portion 42 that stops the fitting portion 41 from being inserted halfway. The outer diameter of the contact part 42 is the same as the outer diameter of the peripheral wall 32 of the inner case 3. The fitting portion 41 is formed with a convex portion 44 that engages with the concave portion 34 of the peripheral wall 32 of the inner case 3. Further, a knob 43 for rotating the inner lid 4 is formed on the outer lid 6 side of the fitting portion 41. In addition, the contact portion 42 is formed with right-angled triangular claws 45 that contact the outer lid 6 to stop the rotation toward the outer lid 6.

  As shown in FIGS. 3 and 5A, the outer case 5 is made of a cup-shaped synthetic resin formed by injection molding, and includes a circular bottom wall 51 and a cylindrical peripheral wall 52. The inner lid 4 is accommodated. The peripheral wall 52 is provided with a slit-like second outlet 53 from which the elastic bandage EB pulled out from the first outlet 33 of the inner case 3 is pulled out.

  FIG. 6A is a view showing the rotational position of the inner case 3 in which the position of the first outlet 33 of the inner case 3 matches the position of the second outlet 53 of the outer case 5. As can be seen from FIG. 6A, the gap G between the outer periphery 32a of the peripheral wall 32 of the inner case 3 and the inner periphery 52a of the peripheral wall 52 of the outer case 5 is different between the left side and the right side. Specifically, the gap G about the half circumference (left side) in the clockwise direction in FIG. 6A from the second outlet 53 is a concentric and uniform fitting gap (R2-R1). On the other hand, the remaining gap G of about half a circumference (right side) has a radius R3 = R2 + ΔL, with the center O2 of the inner periphery 52a of the peripheral wall 52 of the outer case 5 deviating from the center O1 of the outer periphery 32a of the inner case 3 by ΔL. It gradually widens up to 53. In other words, the gap G between the outer periphery 32a of the peripheral wall 32 of the inner case 3 and the inner periphery 52a of the peripheral wall 52 of the outer case 5 gradually increases from the second outlet 53 counterclockwise to about half a circumference. It has become narrower.

  As shown in FIG. 3, two arms 54 extend from the bottom wall 51 to both sides of the second outlet 53 in the outer case 5, and a roller shaft 55 is fixed by an insert. The two roller shafts 55 extend in parallel with the axis of the peripheral wall 52, and the tips thereof are male threads. Further, as shown in FIG. 5A, the outer case 5 is provided with a shaft hole 56 into which the connecting shaft 35 of the inner case 3 is fitted in the center of the bottom wall 51. The shaft hole 56 is formed to be recessed inside the cylinder of the peripheral wall 52. Further, the outer case 5 is formed with a key-like locking piece 57 that locks the outer lid 6 so as to extend to the peripheral wall 52.

  The outer lid 6 is a lid that prevents the inner case 3 and the inner lid 4 housed in the outer case 5 from coming off, and is a ring-shaped synthetic resin having a knob hole 61 into which the knob 43 of the inner lid 4 is fitted. is there. In order to indicate the position of the knob 43 of the inner lid 4 that rotates together with the inner case 3 as shown in FIG. 4B, the outer lid 6 has a scale 62 (“1” in FIG. 4B). “8”) is formed by printing or engraving of a mold.

  Note that the scales 62 used for tension adjustment are provided at substantially equal intervals. This is based on the result of the tensile test on the tension and elongation of the elastic bandage EB performed by the inventor described above. That is, as a result of this test, it is found that it grows abruptly when it exceeds 20N, but it increases in proportion to the tension at about 6N to about 13N, which is suitable for compression therapy. Are attached at substantially equal intervals.

  Further, as shown in FIG. 4A, a plurality of right-angled triangular claws 63 that are engaged in the rotation direction of the inner lid 4 are formed on the inner lid 4 side of the outer lid 6. The outer periphery of the outer lid 6 has substantially the same shape as the outer periphery of the bottom wall 51 of the outer case 5. Similarly to the bottom wall 51 of the outer case 5, the outer lid 6 includes two arms 64 extending outward from the center. The arm 64 is provided with a nut hole 65 into which the nut N is inserted. Further, the outer lid 6 is engaged with the locking piece 57 of the outer case 5 by rotating clockwise. In order to enable this rotation, a notch 66 is provided on the outer periphery of the outer lid 6.

  The first roller R1 includes a pipe-shaped synthetic resin core R11 having a shaft hole R111 fitted into the roller shaft 55 of the outer case 5 and elastic skins R12 and R22 covering the arc surface of the core R11.

  The second roller R2 is also the same as the first roller R1, and is a pipe-shaped synthetic resin core R21 having a shaft hole R211 fitted into the roller shaft 55 of the outer case 5, and an elastic material covering the arc surface of R21. R22.

  The skins R12 and R22 of the first roller R1 and the second roller R2 are made of an elastic material that is difficult to slip with respect to the elastic bandage EB. Further, the gaps from the skins R12, R22 of the first roller R1 and the second roller R2 to the outer periphery of the bottom wall 51 of the outer case 5 are all the same, and are dimensioned to pass through the elastic bandage EB.

The first roller R1 and the second roller R2 have the same shape, but the gap G between the outer periphery 32a of the inner case 3 and the inner periphery 52a of the outer case 5 goes from the second outlet 53 to the back. Accordingly, the first roller R1 is on the gradually narrowing side (right side in FIG. 6 (A)), and the other (left side in FIG. 6 (A)) is the second roller R2.
Note that the two nuts N having female threads are screwed into the roller shaft 55 of the outer case 5 to hold the first roller R1, the second roller R2, and the outer lid 6.

  Next, the assembly method of the bandage winding tool 1 and the mounting method of the elastic bandage EB will be described with reference to FIGS. The user inserts the inner case 3 into the outer case 5 with the coil spring S fitted to the connecting shaft 35 of the inner case 3, and inserts the connecting shaft 35 of the inner case 3 into the shaft hole 56 of the outer case 5. Then, the E-type retaining ring E is fitted into the groove 351 of the connecting shaft 35 using the dedicated jig (step 1).

Thereby, the inner case 3 is pivotally supported by the outer case 5 so that rotation is possible. Further, when the inner case 3 is pressed by the coil spring S and the inner case 3 is pressed backward with a predetermined force or more, the inner case 3 slides backward. By this sliding, the engagement between the claw 45 of the inner lid 4 and the claw 63 of the outer lid 6 can be released.
Next, the user inserts the first roller R1 and the second roller R2 into the roller shaft 55 of the outer case 5 (step 2).
Next, as shown in FIG. 6 (A), the user rotates the inner case 3 so that the first outlet 33 of the inner case 3 is aligned with the second outlet 53 of the outer case 5 (step 3).

Next, in FIG. 6 (A), the user passes the elastic bandage EB through the first outlet 33 and the second outlet 53 so that the rotation at the time of extending the bandage is in the counterclockwise direction, and the first roller R1 on the right side. And the elastic bandage EB is inserted into the inner case 3 (step 4).
Next, the user fits the inner lid 4 into the inner case 3 by fitting the convex portion 44 of the inner lid 4 into the concave portion 34 of the inner case 3 (step 5).

Next, the user pushes down the inner lid 4 in a state where the notch 66 of the outer lid 6 is rotated counterclockwise so that the notch 66 of the outer lid 6 is positioned on the locking piece 57 of the outer case 5, and the outer lid 6 is moved to the outer case 5. And the outer lid 6 is inserted into the locking piece 57 of the outer case 5 (step 6).
Next, the user screws the two nuts N into the roller shaft 55 of the outer case 5 (step 7).

  In this state, the engagement of the claw 45 of the inner lid 4 and the claw 63 of the outer lid 6 prevents the inner lid 4 from rotating in the clockwise direction. Further, in the counterclockwise direction, the inner case 3 and the inner lid 4 are automatically pushed down to the back against the pressing of the coil spring S by the sliding of the inclined surfaces of the claws 45 and 63. Accordingly, when the user turns the knob 43 counterclockwise, the inner lid 4 and the inner case 3 rotate.

  Further, when the user pushes down the knob 43 of the inner lid 4 against the pressing of the coil spring S by the height of the claw 45 or more, the engagement between the claw 45 of the inner lid 4 and the outer claw 6 claw 63 is released. When the knob 43 is rotated in the clockwise direction, the inner lid 4 and the inner case 3 are rotated in the clockwise direction.

  Next, the tension adjusting method will be described with reference to FIG. In FIG. 6A, the bandage winding tool 1 is in an initial state in which the first outlet 33 of the inner case 3 is aligned with the second outlet 53 of the outer case 5. At this time, the knob 43 of the inner lid 4 is at the position “1” of the scale 62 of the outer lid 6.

  Then, in order to obtain the tension desired by the user (desired compression pressure), the knob 43 is rotated counterclockwise and moved to the position shown in FIG. At this time, the knob 43 of the inner lid 4 is at the position “4” of the scale 62 of the outer lid 6 at this position (FIG. 4B).

  When the elastic bandage EB is pulled out at the position of the first outlet 33 in FIG. 6B, the elastic bandage EB receives a frictional resistance in the gap between the outer periphery 32a of the inner case 3 and the inner periphery 52a of the outer case 5, and the tension increases. . Due to this double structure, the tension adjusting portion of the bandage winding tool 1 is a compact tension adjusting mechanism. Further, since this gap becomes narrower toward the back, a large change in tension occurs at a small rotation angle. Therefore, the tension adjusting portion of the bandage winding tool 1 is compact and can adjust the tension in a wide range.

  In order to further increase the tension from the state shown in FIG. 6B, the user may rotate the knob 43 counterclockwise. Conversely, to decrease the tension, the user rotates the knob 43 while pressing the knob 43 clockwise. Rotate to

  Next, the usage state of the elastic bandage EB will be described with reference to FIGS. 4 (B) and 6 (B). 4B and 6B, the knob 43 of the inner lid 4 is at the position “4” of the scale 62 of the outer lid 6, and the elastic bandage EB is wound around the affected part (here, the thigh) F. FIG.

  In the present embodiment, the position of the knob 43 at the scale 62 “4” indicates that the compression pressure when the elastic bandage EB is wound with a 50% overlap on the thigh (F) for compression therapy, for example, This is an adjustment position where the elastic bandage EB is pulled out with a tension of 9N so as to obtain 33.3 hPs (25 mmHg) desired by the user.

  By the way, even when the elastic bandage EB having a different elastic coefficient and frictional force is used even at the position “4” of the same scale 62, the tension of the elastic bandage EB pulled out from the bandage winding device 1 changes. At this time, the position of the scale 62 is adjusted so as to obtain a desired tension. Further, even if the tension is the same, the compression pressure changes if the overlapping state of the elastic bandage EB is changed. At this time, the position of the scale 62 is adjusted so as to obtain a tension for obtaining a desired compression pressure.

Further, the bandage wrapping device of the present invention is not limited to the one used for the elastic bandage EB described in the present embodiment, and can be used for a general bandage. Therefore, when the purpose of use of the bandage is different, for example, when it is used for wound protection or fixation of a sprain site, the compression pressure may be changed. At this time, the position of the scale 62 is adjusted so as to obtain a tension for obtaining a desired compression pressure.
Thus, since the bandage winding tool 1 can adjust tension | tensile_strength according to a condition, the desired compression pressure can be obtained.

  As shown in FIG. 6 (B), the elastic bandage EB accommodated in the inner case 3 faces the first outlet 33 in the counterclockwise direction, makes a U-turn at the first outlet 33, and turns to the second outlet 53 in the clockwise direction. Head. Then, the elastic bandage EB makes a U-turn at the second outlet 53 and goes to the first roller R1 in the counterclockwise direction, and makes a U-turn at the first roller R1 and goes to the second roller R2 in the clockwise direction. The elastic bandage EB is wound around the affected part by rotating the bandage winding tool 1 while the user applies the first roller R1 and the second roller R2 to the affected part F.

  The first roller R1 provided with the skin R12 which is hard to slip with an elastic material can wind the elastic bandage EB while being pressed against the affected area and rolling, so that the entire width direction of the elastic bandage EB can be held with tension. it can. Further, the second roller R2 provided with the skin R22 that is hard to slip with an elastic material can stabilize the inclination of the first roller R1 by winding the second roller R2 while contacting the affected part. Further, since the elastic bandage EB extended and fed from the first holding roller R1 with a predetermined tension is sandwiched between the second roller R2 and the affected part F, the stretched state can be maintained and the predetermined tension can be maintained. .

  In this way, the bandage winding device 1 of the present invention can realize the optimum compression pressure by providing the tension adjusting section for adjusting the tension, and the tension for the elastic bandage EB to be used even by a non-expert. The elastic bandage EB can be wound around the affected area so that the pressure becomes a predetermined pressure.

  The tension adjusting portion in the present embodiment is a mechanism that can adjust the length of the elastic bandage EB from the first outlet 33 to the second outlet 53, and the inner case 3 that is the bandage accommodating portion 2, The lid 4, the outer case 5, the outer lid 6, the coil spring S, and the E-type retaining ring E are included. That is, in this embodiment, the bandage accommodating part 2 becomes a structure which serves as a tension adjustment part. However, the bandage wrapping tool is not limited to such a configuration. For example, a configuration in which a tension adjusting unit is attached in contact with the bandage accommodating unit 2 may be used. In the case of such a bandage wrapping tool, the tension of the elastic bandage EB drawn out from the bandage container is adjusted by the tension adjusting unit.

  Next, a method of taking out the elastic bandage EB from the bandage winding tool 1 will be described. First, the user sets the knob 43 of the inner lid 4 to the position “1” of the scale 62 of the outer lid 6, and aligns the first outlet 33 of the inner case 3 with the second outlet 53 of the outer case 5. Next, the user turns and removes the two nuts N, and then rotates the outer lid 6 counterclockwise. Then, the user unfastens and removes the outer lid 6 from the locking piece 57 of the outer case 5, and finally removes the elastic bandage EB from the inner case 3.

  In addition, although 1st roller R1 and 2nd roller R2 of the above-mentioned embodiment were the same diameters, a different diameter may be sufficient. By changing the diameter of the roller, it is possible to cope with various diameters of the affected area. In addition, the position of the roller can be changed to accommodate various diameters of the affected area.

  It should be noted that the present application is based on the experimental results of FIG. 1 and has been conceived to achieve an optimal compression pressure if the tension for pulling out the bandage is appropriately adjusted, and is not limited to the tension adjusting section of the above-described embodiment. Absent. The present application can be applied to a bandage wrapping device including a tension adjusting unit that adjusts a tension for pulling out an elastic bandage from a bandage accommodating unit that accommodates the bandage. Various methods of friction on the adjustable bandage are conceivable other than those described above. Further, even with a method other than friction, for example, if the method is a method in which the bandage is drawn out electrically, the tension can be adjusted.
