Description

  The present invention relates to a winding device such as a bandage, and in particular, easily and quickly adjusts the winding hardness of a bandage that can be reused in a wound state with a relatively simple configuration. It can be wound up as much as possible. In this specification, the bandage and the like include a so-called bandage and a tape-like band having the same flexibility and stretchability as the bandage and stored and used in a wound state.

  Generally, bandages generally used in the medical field are usually discarded after use, but depending on the field of use, there are many that can be reused after necessary sterilization washing. However, when it is reused, it is not easy to use unless the bandage is stored in a wound state, so it is usually taken up manually by a nurse or the like. On the other hand, there is a problem that the automated winding device is expensive.

  Furthermore, outside of the medical field, for example, in the case of a bandage used to fix fingers and fists in boxing and other martial arts, it should be wound up as tightly as possible due to the nature of being tightly wrapped around the fingers and back of the hand. Desirably, such a hard winding manual work is often imposed as part of the user's own training, but it is not always possible to obtain the desired hardness, and a large amount of bandages at a training gym etc. If it is necessary, it is difficult to process everything manually.

Devices that have been partially improved to solve these problems have also been devised (see Patent Documents 1 and 2). However, in these devices, preparation of a winding operation, that is, a tip of a bandage or the like to be wound is provided. When attaching to the winding shaft of the device, the former is simply wound several times on the winding rod, and the tip of the bandage etc. cannot be fixed sufficiently, and the tip is not fixed during the next winding operation. There is a risk that unwinding may occur. In the latter case, the tip of a bandage or the like is inserted into a detachable bifurcated winding shaft for easy gripping. In the attached state, the insertion direction is not the width direction of the bandage but the longitudinal direction, and in the detached state to the winder, the tip part to the take-up shaft is not after the bandage is set on the hook shaft. Can not be inserted, smooth insertion Rather, preparatory work was a troublesome thing.
Japanese Utility Model Publication No. 63-169556 (page 4, FIG. 1) JP 2001-54537 A (FIG. 3)

  Therefore, when the used bandage is reused after being sterilized or washed, it is easy to handle it at the time of reuse by winding it with a predetermined winding hardness. Therefore, it is desired to realize a winding device that can easily and quickly wind up and that can adjust the winding hardness as appropriate.

  The invention of claim 1 has a gripping part which is cantilevered by a base and can insert a leading end portion of a bandage or the like to be wound from the width direction of the bandage or the like, and is driven to rotate during winding operation. Winding part that constitutes the core, an extending part that is arranged on the upstream side of the winding part and extends the bandage before being wound, and a surface that extends the bandage that reaches further upstream of the extending part It is a winding device such as a bandage that is disposed at a position to be pressed to the side, is cantilevered by a base, and has a braking portion that applies braking to movement of the bandage or the like.

  According to a second aspect of the present invention, the braking portion includes a first slide guide disposed at a position where the bandage or the like reaching the extension portion is stretched and pressed against the surface, and a bandage or the like reaching the first slide guide. The winding device for a bandage or the like according to claim 1, further comprising a second slide guide that is bent and guided in advance.

  According to the first aspect of the present invention, the tip of the bandage or the like can be easily fixed with a relatively simple configuration, the winding of the bandage or the like can be easily and quickly wound, and the winding hardness can be adjusted as appropriate. Since it is possible to provide a winding device that can easily remove a bandage after winding, it is convenient to reuse a large amount for reuse of a normal bandage or training for wearing a bandage. Furthermore, due to the cantilever structure of the winding portion, insertion and removal of a wound bandage and the like can be performed smoothly without hindrance.

  Further, according to the invention of claim 2, since appropriate braking is applied to the wound bandage or the like by the ride guide, wrinkles such as the bandage are sufficiently stretched by the extended portion, and the appropriate winding hardness is achieved. Winding is possible.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

  Reference numeral 1 denotes a base, and a drive motor 3 is disposed on a standing part 2 (shown in FIG. 2) with its drive shaft 4 positioned horizontally. The motor 3 is turned on and off by a switch 7 of an operation unit 6 disposed on the front surface of the cover 5 of the base 1, and the drive shaft 4 is connected via a gear train (not shown) by a speed dial 8 of the operation unit 6. It is configured to be able to rotate at an arbitrary winding speed.

  Further, from the cover 5 facing the upright portion 2 of the base 1, a rotatable base 9 is connected to the drive shaft 4 of the drive motor 3, and the rotatable base 9 protrudes. The winding part 10 which comprises a winding core is installed. The winding portion 10 is cantilevered by the base 1, and is connected to the rotating base portion 9, and a winding core body 11 having its own axis as the center of rotation, and the winding core body 11 is wound together with the winding core body 11. Consists of a sub-frame 12 that constitutes a core, is connected to the rotating base 9 in the vicinity of the core body 11, and is arranged so as to be next to the core body 11 so as to be able to rotate integrally therewith. Is done.

  By projecting the distal end portion of the secondary frame 12 in the distal direction from that of the core body 11, the user can place the distal end portion of the bandage between the core body 11 and the secondary frame 12 in the width direction. Since the tip of the sub-frame 12 can be used as a guide for the bandage insertion operation when it is inserted, the insertion operation can be facilitated.

  The winding portion 10 is preferably formed such that the core body 11 and the sub-frame 12 are fixedly formed at the base end side, and the width direction of the bandage T or the like described later along the axial direction. A gap g capable of sandwiching the leading end inserted into the winding portion 10 is formed, and at least at the leading end side of the winding portion 10, the auxiliary frame 12 is configured to elastically contact the winding core body 11.

  In this embodiment, the core body 11 has an outer diameter of about 6 mm, and the sub-frame 12 has a metal round bar with an outer diameter of about 4 mm. The smaller the is, the smaller the looseness of the central part after the winding is completed as described later, and the firm winding can be maintained.

  And as mentioned above, if the front-end | tip part of bandages etc. T is inserted between the core main body 11 and the subframe 12 of the winding part 10 in the width direction, the front-end | tip parts of bandages etc. will be elastic in the meantime. It is sandwiched between.

  In addition, the winding core body 11 and the auxiliary frame 12 of the winding part 10 are inserted into the center part of the winding part 10, and the rotation side plate 13 is disposed near the rotation base part 9 on the base end side thereof. The rotating side plate 13 serves as a pressing plate for guiding the side surface during winding of the bandage and for extracting the bandage from the winding unit 10 after the winding is completed.

  In this case, the two rotation side plates 13 are arranged in a stacked manner, the rotation side plate 13 on the cover 5 side is fixed, and the front rotation side plate 13 can be moved as a pressing plate for extracting T such as a bandage. Also good.

  Further, the cover 5 of the base 1 is located in the radial direction away from the rotary side plate 13 and on the near side of the winding portion 10, that is, upstream in the moving direction of the bandage T, and substantially the same as the winding portion 10. The extending portion 20 parallel to the can 20 is cantilevered at the height, and the end portion is supported by the auxiliary column 21 and installed. The stretched portion 20 is formed with a stretched plate 22 having a loose convex surface on its upper surface, and the portion immediately before the bandage T wound around the take-up portion 10 is in strong contact with the stretched plate 22. The wrinkles formed along the longitudinal direction of the bandage T are stretched. In addition, it is preferable that a heater for heating can be incorporated in the extended portion 20.

  Further, it is located on the further front side of the stretched portion 20, that is, on the upstream side in the winding direction of the bandage T and the like, and is arranged on the side surface of the base 1 in parallel with the winding portion 10 so A braking guide portion 25 including a pair of columnar slide guides 23 and 24 that are spaced apart from each other in a direction is provided on the base 1 in a cantilevered manner. The upper slide guide 23 is arranged at a position where the bandage T or the like is directed upward toward the surface of the extension plate 22 of the extension portion 20, and the lower slide guide 24 is shown in the drawing. As described above, a bandage T or the like wound around the side of the base 1 is suspended from the slide guide 23 in an S shape.

  That is, the user of the device of the present invention applies a brake also by the slide guide so as to apply a predetermined tension to the bandage T that is being rolled up while holding the bandage T to be wound up with both fingers. However, it is configured to allow the winding operation by sliding between fingers.

  Describing the operation of the winding device of the present invention configured as described above, roughly speaking, in the state where the user holds a bandage to be wound, the tip portion is wound from the width direction. The tip of the bandage or the like is temporarily taken up and gripped by inserting it into the holding part and rotating the winding part several times. In this state, the bandage and the like are moved by the stretched part by rotating the winding part while holding the bandage and the like with the fingers through the stretched part and the braking part. The wrinkles are rolled up while being stretched.

  And, by applying a certain tension to the bandage or the like, and appropriate braking is applied by the first and second slide guides, the bandage or the like is wrinkled by the extending portion, and It is wound around the winding portion with an appropriate winding hardness.

  In the following, in more detail, the user first turns off the switch 7 of the device and places the speed dial 8 at the lowest speed, first the user needs to take up, is not wound. Or a bandage T or the like in a loosely wound state, and the leading end of the bandage or the like T in the gap g between the core body 11 and the auxiliary frame 12 on the leading end side of the winding unit 10 from the width direction. The leading end of the bandage T is inserted and temporarily held by the winding unit 10.

  When the switch 7 is turned on in this state, the drive motor 3 rotates at a low speed, and the leading end portion of the bandage T is wound around the winding portion 10 several times. In this manner, with the distal end portion of the bandage T temporarily temporarily held by the winding unit 10, the portion continuing from the distal end portion of the bandage T is the upper side of the stretch plate 22 surface of the stretch portion 20 and the slide guide. It is inserted through the upper side of 23 and the lower side of the guide 24 so as to follow the S shape. Then, the user grips the bandage T with fingers and applies an appropriate tension, and as a result, the secondary frame 12 is fastened to the core body 11 by the wound-up tip of the bandage T, etc. The leading end of the bandage T is securely held by the winding unit 10.

  In this state, when the speed dial 8 is turned to the high speed side, the winding is started, and the user performs braking while pulling the bandage T being held, so that the bandage T and the like further slide guides 23, 24. Is slid by sliding on the surface of the belt, and an appropriate tension is applied. As a result, the bandage T is stretched and pressed against the surface of the stretch plate 21. Accordingly, the bandage T is wound around the winding portion 10 with a required hardness while the wrinkles are stretched and the side edge positions thereof are guided and aligned by the rotating disk 8.

  Thus, after the full length has been wound up, the wound band T or the like T is pressed by pulling out the rotating side plate 13 in the axial direction, and the tip of the bandage T located in the gap g of the winding portion 10 The part also moves in the width direction and is pulled out and can be easily removed.

  In the case of the winding operation, the moving speed of the bandage T is experimentally easy to handle about 20 to 80 cm per second, and preferably 50 to 60 cm is smooth.

  Further, the adjustment of the winding hardness is based on how to apply tension to the bandage T at the time of winding, and can be arbitrarily adjusted by the user holding the bandage T and braking it with a finger together with fingers. It is.

  The wound tightness of the bandage T will be described. In the case of medical use, it is necessary to wrap around the treatment site including the affected part with appropriate flexibility, and therefore, 30 layers per centimeter thickness with a normal gauze bandage. Although the degree is general, in the case of a bandage for fixing a fist or the like in boxing or other martial arts, winding as hard as possible is preferable, and for example, about 60 layers per centimeter thickness are required.

  Describing another embodiment of the present invention, the first and second slide guides 23 and 24 first slide the bandage T toward both ends in the width direction when the bandage T is advanced in the winding direction. In order to have a tendency to move on the guide, any of them can be formed into a gentle drum shape in which the middle abdomen gradually increases from the end.

  Moreover, the winding part 10 can make it easy to pull out the wound bandage T from the winding part 10 by comprising the taper shape which has a gentle taper toward the front end side from the base end side.

  Furthermore, when the wound bandage T is pulled out, when wound up considerably hard, the central part is tightly wound around the core body 11, so that the central part cannot be pulled out smoothly. Since it is assumed that the winding may collapse if it is pulled out in a state where it is left behind, the winding core body 11 and the auxiliary frame 12 can be formed as a cover winding core. Each of the cover winding cores is a cover in which a pair of slits are formed in the axial direction thereof, and is formed so as to be removably fitted into the winding core body 11 and the auxiliary frame 12 from the axial direction.

  Therefore, after the bandage T is wound up as described above with the cover winding core attached, the cover winding core is also wound around the winding core T by either pulling out the bandage T directly in the axial direction or with the rotating side plate 13 in the axial direction. It is pulled out from the main body 11 and the auxiliary frame 12 in the axial direction. In this state, the cover winding core taken into the central part of the drawn bandage T can be easily removed from the wound bandage T or the like and reused.

  In addition, the winding unit 10 is configured by the winding core body 11 and the sub-frame 12, but the winding unit 10 is configured by only three core body members having the same diameter that are close to each other. The core body member is constructed so that it is placed on the rotation base 9 so as to be located at each vertex of an equilateral triangle centered on the rotation axis and protrudes to the side, and its tips are in contact with each other. Can do. As a result, the user inserts the distal end portion of the bandage T in the width direction between the core body members, and first temporarily winds and fixes the distal end portion by several windings, and then stabilizes normally. Then, the winding can be executed.

  Even in the case where the three core body members are configured as described above, it is easy to insert the distal end portion of the bandage T by projecting one distal end side from the other of the three core members. Can do.

  The sub-frame 12 has a semicircular groove having a semicircular cross section on the outer periphery along the axial direction at least at the tip of the core body 11, and a part of the subframe 12 fits into the groove. By arranging in this way, it is possible to prevent the auxiliary frame 12 from being twisted with respect to the core body 11 due to the winding pressure of the bandage T when the bandage T is wound.

  Furthermore, in order to make it easy to pull out the wound bandage T, the winding core body is composed of a single solid metal bar, and a slit is formed from the longitudinal end of the metal bar and is inserted into the slit. An elastic body such as rubber or a leaf spring having a friction holding force with the slit being separated can be arranged so that it can be temporarily fixed when a bandage T or the like is inserted in the width direction, and the slit is also retained after winding is completed. It is possible to extract the wound bandage T and the like relatively easily by selecting one having almost no deformation in shape.

  Moreover, although the extending part 20 in the said Example comprised the extending plate 22 and the auxiliary | assistant support | pillar 21, it replaces with the extending part 20 in the said slide guide 23, and arrange | positions it in the position. The extension plate 22 cannot be used, but the slide guide 23 can form an extension surface, and the use of only the slide guide 24 for braking can simplify the overall configuration.

  Further, in the above-described embodiment, the on / off switch 7 and the speed dial 8 are arranged on the left and right in the front view of FIG. 2, respectively. It is also possible to make it.

  In addition, although both are installed separately, an on / off switch is integrated into the speed dial 8 and functions as an on / off switch at a speed 0 position like a volume with a switch. By making the speed increase / decrease function, the configuration and operability can be simplified and simplified.

  Furthermore, after the operation of the on / off switch 7, by rotating the speed dial 8, the rotational speed can be shifted from the minimum speed to a high speed, thereby temporarily winding the bandage T for holding the tip. The original winding having a desired winding hardness can be smoothly operated.

  Furthermore, the reverse rotation dial that controls the reverse rotation at low speed is juxtaposed, so that it is necessary to operate the reverse rotation switch when it is necessary to unwind for some reason after winding the tip of the initial bandage T several times. By doing so, it is possible to easily rewind.

  Further, as an overall arrangement, in the illustrated embodiment, the operation unit 6 side is located on the left side of the base 1, but depending on the usability of the dominant hand, it may be arranged on the right side of the noble base.

The perspective view which shows one Example of this invention. Similarly front view. Similarly side view.
