Description

  The present invention relates to a bandage wrapping tool capable of being wound with a constant bandage tension.

  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 complication 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. In addition, elastic bandages are not only “compressed” but also dressed as “wound protection”, as “fixed”, fixed and rested on fractures, dislocations, sprains, and dressings and drugs that are easily displaced as “holding / supporting” It is also used for holding and supporting drip tubes and cines.

  The elastic bandage must be wrapped 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). Since the pressure of the capillaries is 42.7 hPs, applying more pressure with an elastic bandage will block the capillaries and prevent blood from passing through the skin tissue. There 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.

  An elastic bandage is mainly wound by a nurse, but in order to wrap around an 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.
Accordingly, an object of the present invention is to provide a bandage wrapping tool that can be wound around an affected part with a constant tension of the bandage even if it is not an expert.

  In order to solve the above-described problem, a bandage winding device according to one aspect of the present invention includes a resistance applying mechanism that applies a resistance force to a bandage drawer in the bandage extraction path.

  When the pulling force of the bandage is less than this resistance force, it will not be pulled out of the bandage, and when the pulling force of the bandage is higher than this resistance force, the bandage will be pulled out of the bandage winding tool against the resistance force, It can be wound around the affected area with a predetermined tension. Therefore, in the use of an elastic bandage that requires skill, the elastic bandage can be wound around the affected part with a predetermined tension without being an expert.

Moreover, in the bandage winding tool of this invention, it is preferable that the said resistance provision mechanism provides a resistance force equally with respect to the width direction of drawer | drawing-out of a bandage.
Thereby, the present invention can make the tension in the width direction uniform. Therefore, when the bandage wrapping tool is not used, the elastic bandage side can be pulled against the thumb (thumb) and the thumb ball to prevent the tension in the width direction of the elastic bandage from becoming uniform. it can.

Moreover, in the bandage winding tool of this invention, it is preferable that the said resistance provision mechanism provides a fixed resistance force.
Thereby, since the force which pulls out a bandage from a bandage winding tool can always be made uniform, this invention can prevent the problem that tension | tensile_strength does not become uniform if resistance force is increased / decreased by the force control by hand.
Moreover, in the bandage winding tool of this invention, it is preferable that the said resistance provision mechanism can adjust the applied resistance.
The compression force varies depending on the site and purpose of winding the elastic bandage, but the present invention can cope with this.

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.
[First Embodiment]

  The bandage winding tool 1 of 1st Embodiment is demonstrated using FIG. The first embodiment shows the basic configuration of the present invention. This bandage winding tool 1 is provided with a resistance applying mechanism for applying a resistance force to the bandage drawer in the bandage extraction path. More specifically, the bandage winding tool 1 includes a housing 2 that houses the elastic bandage B and a resistance applying mechanism 3.

  The housing 2 has a structure in which the elastic bandage B is stored and the stored elastic bandage B can be pulled out. And the path | route from the elastic bandage B accommodated in this housing | casing 2 to the affected part which winds the elastic bandage B becomes a drawing-out path | route of a bandage.

  The resistance applying mechanism 3 provides resistance to the force with which the elastic bandage B is pulled out from the housing 2. The resistance applying mechanism 3 is provided in the pull-out path of the elastic bandage B, and the position of the resistance applying mechanism 3 is within the housing 2 or outside the housing 2 (including the surface of the housing 2) or the same. It may be provided in both. Various methods of resistance by the resistance applying mechanism 3 are conceivable. For example, a frictional force with the elastic bandage B or an internal resistance of the feeding mechanism of the elastic bandage B may be used.

With this resistance applying mechanism 3, the elastic bandage B cannot be pulled out unless a predetermined force or more is applied. Further, since the resistance force by the resistance applying mechanism 3 is constant, there is no influence of individual pulling force, and even if the remaining amount (diameter) of the elastic bandage B in the housing 2 changes, the elastic bandage The force with which B is pulled out is constant. Further, since the resistance force by the resistance applying mechanism 3 is applied evenly in the width direction of the elastic bandage B, the tension of the thumb or thumb ball portion does not increase. Moreover, since this resistance provision mechanism 3 is provided with the function to adjust the tension | tensile_strength mentioned later, the compression force in the elastic bandage B can be adjusted, for example.
[Second Embodiment]

  Next, the bandage winding tool 1A of the second embodiment will be described with reference to FIGS. The second embodiment shows a specific example of the first embodiment. In the bandage winding tool 1A of the second embodiment, parts having the same configuration as the bandage winding tool 1 of the first embodiment are denoted by the same reference numerals, detailed description thereof is omitted, and the same names differing in configuration. For the part, the subscript “A” is added to the reference symbol.

  The bandage winding tool 1A according to the second embodiment includes a housing 2A that accommodates the elastic bandage B and a resistance applying mechanism 3A that can adjust the applied resistance force. More specifically, as shown in FIG. 2 and FIG. 3, the bandage winding tool 1 </ b> A includes a casing 2 </ b> A including a case 21 and a lid 22, a resistance applying mechanism including a resistor 31, an adjusting screw 32, and a support 33. 3A.

  First, the case 21 and the lid 22 forming the housing 2A are made of synthetic resin (for example, ABS resin or styrene resin) formed by injection molding. The case 21 and the lid 22 accommodate the elastic bandage B by inserting the elastic bandage B from the circular mouth of the cylindrical case 21 and fitting the lid 22 into the circular mouth. Then, the stored elastic bandage B is pulled out of the case 21 from the drawer opening 21 a of the case 21. Note that an arc-shaped cutout 21aa is provided in the center of the outlet 21a so that the elastic bandage B can be easily pulled out.

  The case 21 has a first hook hole 21b into which a later-described hook 31a of the resistor 31 is inserted, a second hook hole 21c into which a later-described hook 33b of the support 33 is inserted, and a later-described guide of the support 33. Two guide holes 21 d into which 33 c are inserted are provided in the vicinity of both ends of the case 21. The housing 2A can also be formed of metal.

  Next, the resistance applying mechanism 3A capable of adjusting the applied resistance force will be described. The resistor 31 is made of a synthetic resin formed by injection molding. The resistor 31 is in the shape of an arc column covering substantially half of the arc surface of the case 21, and includes hook-like hooks 31 a on the left and right of the rear end of the arc, and abuts the elastic bandage B on the front end of the arc. A contact portion 31b is provided. In addition, a rib 31c extending in the opposite direction to the case 21 is formed at the front end of the arc, and this rib 31c serves as a reinforcement for the contact portion 31b.

  In addition, the resistor 31 is configured such that the two hooks 31 a are fitted into the two first hook holes 21 b of the case 21, and the end of the resistor 31 on the contact portion 31 b side covers the drawer port 21 a of the case 21. ing.

  As a result, the elastic bandage B is sandwiched between the abutting portion 31b of the resistor 31 and the circular arc surface in the vicinity of the outlet 21a of the case 21. Then, the sandwiched force becomes a resistance force by which the elastic bandage B is pulled, thereby functioning as a resistance applying mechanism. In addition, you may change partially the shape and material of the part to pinch | interpose so that this resistance force turns into desired resistance force. For example, the contact portion 31b may be comb-shaped or another friction material may be attached.

  The resistor 31 can be detached from the case 21 by removing the hook 31a from the first hook hole 21b. The resistor 31 can be rotated with the hook 31a as a fulcrum. Therefore, as a preparation for winding the elastic bandage B around the affected part, the bandage winding tool 1A can be easily obtained by rotating the resistor 31 and widening the gap between which the elastic bandage B is sandwiched while the resistor 31 is mounted on the case 21. The elastic bandage B can be pulled out slightly.

  The adjustment screw 32 is for adjusting the resistance force applied by the resistance applying mechanism 3 </ b> A, and is held by the case 21 by the support 33. The adjustment screw 32 is printed with a numerical value 32a which is a scale on the head, and a non-slip knurled is engraved on the side of the head.

  The support 33 is made of a synthetic resin formed by injection molding, and has a circular arc column shape that covers a portion excluding the front end of the resistor 31. Further, the support 33 protrudes toward the case 21 at the right and left ends of the front end, the screw hole 33a into which the adjusting screw 32 is screwed into the center of the front end of the arc, the hook 33b at the left and right of the rear end, and the left and right ends of the front end. A guide 33c is provided. The support 33 is engraved with a triangular index 33d in the vicinity of the screw hole 33a, and the resistance applying mechanism 3A has a target scale from among the numerical values 32a of the adjustment screw 32 according to the index 33d. It is configured to match.

  The support 33 has a configuration in which two hooks 33 b are fitted into the second hook holes 21 c of the case 21 and two guides 33 c are fitted into the guide holes 21 d of the case 21 to cover a part of the resistor 31. It has become. Then, the support 33 can be detached from the case 21 by removing the hook 33b from the second hook hole 21c. Further, the support 33 can be rotated around the hook 33b. Therefore, as a preparation for winding the elastic bandage B around the affected part, the bandage wrapping tool is obtained by rotating the support body 33 and widening the gap between the elastic bandages B while the resistor 31 and the support body 33 are attached to the case 21. 1A can easily pull out the elastic bandage B slightly.

  With this configuration, when the support 33 is pressed against the case 21 by the thumb and the thumb ball, the resistance applying mechanism 3A presses the resistor 31 against the case 21 by the screw tip 32b of the adjustment screw 32. The elastic bandage B is sandwiched between the abutting portion 31b of the resistor 31 and the circular arc surface in the vicinity of the drawer opening 21a of the case 21. This sandwiched force becomes a resistance force when the elastic bandage B is pulled, and the elastic bandage B is pulled out with a constant tension.

  Further, since the elastic bandage B is sandwiched between the circular arc surfaces near the outlet 21a by the contact portions 31b arranged in parallel across the entire width direction of the elastic bandage B, the resistance is uniform in the width direction of the elastic bandage B. And is pulled out with uniform tension.

  The magnitude of this resistance force by the resistance applying mechanism 3A is always constant because the gap between the contact portion 31b and the case 21 is kept constant depending on the position of the adjusting screw 32. Accordingly, the resistance applying mechanism 3A also functions as a mechanism that always applies a certain resistance force. Then, by turning the adjusting screw 32, the position of the adjusting screw 32 (depth at which the adjusting screw 32 is screwed into the support 33) is changed, and the magnitude of the resistance force can be changed. Thereby, a compression force can be changed suitably according to the site | part and purpose which wind the elastic bandage B. FIG. Therefore, the resistance applying mechanism 3A also functions as a mechanism capable of adjusting the applied resistance force.

  The tension adjustment range by the adjustment screw 32 is set so that the compression force is 26.7 hPs to 40 hPs (20 mmHg to 30 mmHg) with a predetermined number of turns. In this setting, it is necessary to obtain the relationship between the compression force and tension at a predetermined number of turns of the elastic bandage B to be used. For example, it may be graphed by experimental values, or an approximate expression may be obtained by the least square method of regression analysis in statistics.

Moreover, although the resistor 31 and the support body 33 were synthetic resins, in order to increase intensity | strength more, the metal formed by sheet metal processing may be sufficient. At this time, it is preferable that the end of the contact portion 31b of the resistor 31 is hemmed to prevent injury and further increase the strength. Moreover, it is preferable that the screw hole 33a of the support body 33 is screwed into a burring hole in order to extend the length of the female screw. In addition, in FIG.2 (B), the reference figure when the bandage winding tool 1A is actually used is shown. As shown in FIG. 2 (B), the bandage winding tool 1A is used with the support 33 being pressed against the case 21 by the thumb and thumb ball.
[Third Embodiment]

  A bandage winding tool 1B according to a third embodiment will be described with reference to FIGS. 5 (A) and 5 (B). In the bandage winding tool 1B of the third embodiment, the adjusting screw 32 and the support 33 are deleted from the bandage winding tool 1A of the second embodiment, and the rolling mechanism 4 is added. In the bandage winding tool 1B of the third embodiment, parts having the same configuration as the bandage winding tool 1 of the second embodiment are denoted by the same reference numerals, detailed description thereof is omitted, and the same names differing in configuration. For the part, the subscript “B” is added to the reference symbol.

  As shown in FIGS. 5 (A) and 5 (B), the bandage winding device 1B of the third embodiment does not have the adjusting screw 32 and the support 33, but has the resistor 31 as the resistance applying mechanism 3B. There is an effect that the force with which the bandage B is drawn out becomes uniform in the width direction of the elastic bandage B.

  The rolling mechanism 4 according to the third embodiment includes two rollers 41. The roller 41 has a cylindrical shape in which the height of the synthetic resin formed by injection molding is low, and a bearing 41a is provided at the center. The bearings 41a of the respective rollers 41 are fitted into shafts 23 provided at the center of the circular surface of the case 21B and the center of the circular surface of the lid 22B (not shown), so that the two rollers 41 are rotatably supported. ing.

  Thereby, in the bandage winding tool 1B, the circular arc surface of the roller 41 becomes the rolling surface 41b, and this rolling surface 41b can roll the elastic bandage B by rolling the affected surface. At this time, the bandage wrapping tool 1B can roll the affected part surface while the angle at which the elastic bandage B is drawn out is always constant with respect to the affected part surface. Therefore, when the elastic bandage B is wound around the affected part, the operation can be easily performed. In particular, until the first roll, the elastic bandage B comes off the affected area unless the tip of the elastic bandage B is pressed with the other hand, so the bandage winding tool 1B has to be rotated with one hand. In this respect, the band winding tool 1B of the present embodiment can easily roll the affected area, and therefore, the first one winding operation is particularly easy. In addition, the rolling mechanism 4 of 3rd Embodiment is applicable also to 1st-2nd embodiment.

  As described above, by using the bandage wrapping tool of the present invention, even an unskilled person can easily wind the elastic bandage B around the affected area. The specific structure of the resistance applying mechanism in the bandage winding device of the present invention is not limited to the structure of the resistance applying mechanism 3A as shown in the second embodiment, and other structures may be adopted. it can.

  Moreover, even if the bandage winding tool of the present invention is used, it may be necessary to rewind it while it is being wound. In particular, the bandage wrapping tool that does not include the rolling mechanism 4 has a risk that the elastic bandage B may be loosened because the first roll must be wound around with one hand. Also, the patient may move during the bandaging operation. When the operation using the bandage wrapping tool is interrupted in this way, the elastic bandage B is removed from the bandage wrapping tool at one end, the elastic bandage B is wound in the original state, and the elastic bandage B is again used as the bandage wrapping tool. Must be housed. Therefore, it is more preferable to provide a mechanism for winding the elastic bandage B while the elastic bandage B is accommodated in the bandage winding tool of the present invention. Thereby, even if the bandage winding operation is interrupted, the elastic bandage B can be wound without removing the elastic bandage B from the bandage winding tool.

In addition, for example, when the elastic bandage B starts to overlap at the beginning of the second roll, it may be necessary to slightly pull the elastic bandage B slightly so that the elastic bandage B does not easily come off. In such a case, the bandage winding device can be provided with a stop mechanism for stopping the drawer for a certain period so that the elastic bandage B is not pulled out even if the elastic bandage B is pulled out with a predetermined tension or more. In addition, it is preferable that this stopping mechanism prevents an excessively large pulling force from being applied. For example, in addition to the normal resistance applying mechanism that provides the elastic bandage B with the resistance to draw R1, an auxiliary resistance applying mechanism (stopping mechanism) that provides the resistance to draw R2 is provided. If the auxiliary resistance applying mechanism is turned on only when the elastic bandage B slightly overlaps in the second roll, and it is wound strongly with the pull-out resistance of R1 + R2, the elastic bandage B will not easily come off. At this time, since the tension exceeding R1 + R2 is not applied, it is possible to prevent the patient from suffering and the elastic bandage B from exceeding the critical elastic modulus.
In addition, although the bandage winding tool 1 of the above-mentioned embodiment used the elastic bandage B, even if it uses it for a general bandage, there exists an effect which winds a bandage by predetermined tension.
