Description

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

Blood in the veins of the extremities needs the help of relaxation of the muscles that act as pumps to circulate at normal speed. The veins have valves, and the contraction of the muscles compresses the deep veins and sends blood to the central side. Then, the blood on the peripheral side is sucked up by the relaxation of the muscle. This is the role of the muscle pump. When the blood flow velocity in the vein becomes slow, deep vein thrombosis (DVT, economy class syndrome) in which blood clots occur is likely to occur. In particular, the lower limbs, which are in the direction of blood flow against gravity, are more likely to develop blood clots. There is a risk of developing pulmonary thromboembolism in which this thrombus peels off (frees up) and clogs the pulmonary artery.

There are various factors that slow down the flow of veins. In surgically anesthetized patients, the action of anesthesia induces vasodilation and slows venous blood flow. Continue exercising in the same position due to long-term lying down, post-surgery or fractures of the lower limbs, elderly or disabled people who have difficulty walking, long-term riding of vehicles, evacuation life in the event of a disaster, and industries that stand still. If not, the muscle pump will be insufficient and the blood flow rate will be slowed down.

As a preventive method for deep vein thrombosis, there is a method of using an anticoagulant, but there is a risk that blood does not stop easily when bleeding occurs. There is a compression method as a method without this risk. By compressing the limbs, the blood vessels become slightly thinner and the blood flow velocity increases. As a method of this compression, as disclosed in Patent Document 1, an intermittent air compression method (pneumatic pump, IPC) in which air is intermittently sent from a device to a fitting wrapped around the lower limbs to compress the lower limbs. ). However, because the intermittent air compression method has a pumping function, if there is a suspicion of deep vein thrombosis in the presence of deep vein thrombosis, there is a risk of peeling off the thrombus attached to the vein wall and causing pulmonary embolism. As a general rule, do not use it because it has sex. Also, intermittent air compression cannot be used during orthopedic traction.

As another compression method, there is medical elastic stockings as disclosed in Patent Document 2. Since the compression force of commercially available compression stockings is 20 hPs (15 mmHg) or less, the compression force for medical use is stronger than that on the market. Also, for medical use, the pressure on the ankle is the strongest and the pressure on the thigh is weakened in order to facilitate the flow of venous blood and lymph toward the heart. However, medical elastic stockings have ready-made dimensions such as S, M, and L sizes, 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 off-the-shelf products are not suitable for patients with large lymphedema or deformed limbs. In addition, although the compression force differs between the case of deep vein thrombosis and the case of edema, the compression force cannot be changed in medical elastic stockings.

Therefore, a method of wrapping an elastic bandage around a limb as disclosed in Patent Document 3 has been considered. Elastic bandages can be used in any shape of the lower limbs and are characterized by the ability to adjust the compression pressure and range according to the condition of the condition and the condition of the limbs. Elastic bandages can be used to compress the limbs even if the elastic stockings cannot be worn, the size does not fit, or the leg is interrupted due to skin problems, or the stockings cannot be worn due to surgery or deformity of the lower limbs. This elastic bandage compression is used not only to prevent deep vein thrombosis, but also to control hemostasis and edema, treat varicose veins of the lower extremities, and treat lymphedema. In addition, elastic bandages are not only "compression" but also bandages for "wound protection", "fixation" for fixation and rest of fractures, dislocations, and sprains, and "holding and support" for dressings and drugs that are easily displaced. It is also used for holding and supporting drip tubes and sprains.

Japanese Patent Application Laid-Open No. 2001-514407 Japanese Unexamined Patent Publication No. 2014-188116 Special Table 2015-526224 Japanese Unexamined Patent Publication No. 2002-78731 Japanese Unexamined Patent Publication No. 2001-137290

The elastic bandage should be wrapped around the affected area with a predetermined range of pressure. For example, for the prevention of deep vein thrombosis, the pressure should be 26.7 hPs to 40 hPs (20 mmHg to 30 mmHg). The pressure of the capillaries is 42.7 hPs, so if you apply more pressure with an elastic bandage, the capillaries will become occluded and blood will not pass through the skin tissue, so to prevent pressure ulcers, keep it below this value. There must be. In addition, when compressing the lower limbs, the ankle pressure must be strongest and the pressure weaker toward the thigh to facilitate the flow of venous blood and lymph toward the heart. For example, the ratio is ankle: calf: thigh 10: 7: 4.

The elastic bandage is mainly wrapped by a nurse, but in order to wrap it around the affected area at a predetermined pressure, the elastic bandage must be pulled with a predetermined tension and the number of turns must be set. It is not so difficult to achieve a predetermined number of turns, but it is very difficult to pull an elastic bandage with a predetermined tension, and skill is required. Even though he teaches various techniques, the current situation is that he depends on the feelings of nurses, and there is a problem that individual differences occur. Further, when a wide elastic bandage is wrapped, the tension is not uniform in the width direction because the elastic bandage side is applied to the thumb and the ball of the thumb and pulled. Due to the variation in pressure due to the elastic bandage, it is necessary to untie the elastic bandage and frequently check for abnormalities such as redness.

Patent Document 4 discloses a bandage on which a mark indicating the degree of elongation is formed, but this problem cannot be solved without using the bandage. It should be noted that the market for this bandage cannot be confirmed.

Further, although Patent Document 5 discloses an automatic bandage device for wrapping a bandage, it is not possible to confirm that such an automatic bandage device is commercially available, and the method of use and the effect of the use are described from this document. Hard to understand. In Patent Document 5, it seems that the tension of the bandage is adjusted by adjusting the rotation of the bandage by pressing the finger, but the tension of the bandage is not directly adjusted, and the place different from the bandage is adjusted by the finger. It is configured to suppress.
Therefore, an object of the present invention is to provide a bandage wrapping tool that can be wrapped around an affected area with a constant tension of the bandage even if the person is not an expert.

In order to solve the above problems, the bandage wrapping tool according to one aspect of the present invention is characterized in that the bandage withdrawal path is provided with a resistance applying mechanism for applying a resistance force to the bandage withdrawal.

When the withdrawal force of the bandage is less than this resistance, it is not pulled out from the bandage, and when the withdrawal force of the bandage is more than this resistance, the bandage is pulled out from the bandage wrapping tool against the resistance. It can be wrapped around the affected area with a predetermined tension. Therefore, in the use of an elastic bandage that requires skill, even a non-skilled person can wrap the elastic bandage around the affected area with a predetermined tension.

Further, in the bandage wrapping tool of the present invention, it is preferable that the resistance applying mechanism uniformly applies a resistance force in the width direction of the pulling out of the bandage.
Thereby, the present invention can make the tension in the width direction uniform. Therefore, when the bandage wrapping tool is not used, the problem that the tension in the width direction of the elastic bandage is not uniform can be prevented by pulling the elastic bandage side against the thumb and the ball of the thumb. can.

Further, in the bandage wrapping tool of the present invention, it is preferable that the resistance applying mechanism imparts a constant resistance force.
As a result, according to the present invention, the force for pulling out the bandage from the bandage wrapping tool can be made uniform at all times, so that it is possible to prevent the problem that the tension becomes not uniform when the resistance force is increased or decreased by adjusting the force of pressing by hand.
Further, in the bandage wrapping tool of the present invention, it is preferable that the resistance applying mechanism can adjust the applied resistance force.
The compression force differs depending on the site and purpose of wrapping the elastic bandage, and the present invention can cope with this.

Hereinafter, embodiments for carrying out the present invention will be described with reference to the embodiments and drawings, but the embodiments shown below are not intended to limit the present invention to those described herein. The invention can be equally applied to those made with various modifications without departing from the technical idea shown in the claims. In each drawing used for the explanation in this specification, in order to make each member recognizable in the drawing, the scale is different for each member, and it is not always actual. It is not displayed in proportion to the dimensions of.
[First Embodiment]

The bandage wrapping tool 1 of the first embodiment will be described with reference to FIG. The first embodiment shows the basic configuration of the present invention. The bandage wrapping tool 1 is provided with a resistance applying mechanism for applying a resistance force to the bandage withdrawal in the bandage withdrawal path. More specifically, the bandage wrapping tool 1 includes a housing 2 for accommodating the elastic bandage B and a resistance applying mechanism 3.

The housing 2 has a structure in which the elastic bandage B can be stored and the stored elastic bandage B can be pulled out. Then, the path from the elastic bandage B housed in the housing 2 to the affected part around which the elastic bandage B is wrapped becomes the bandage withdrawal path.

The resistance applying mechanism 3 applies 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 inside the housing 2, outside the housing 2 (including the surface of the housing 2), or the surface thereof. It may be provided on both sides. Various methods of resistance by the resistance applying mechanism 3 can be considered. For example, the frictional force with the elastic bandage B may be used, or the internal resistance of the feeding mechanism of the elastic bandage B may be used.

Due to this resistance applying mechanism 3, the elastic bandage B cannot be pulled out unless a force equal to or higher than a predetermined value is applied. Further, since the resistance force by the resistance applying mechanism 3 is constant, there is no influence due to individual differences in the 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 evenly applied in the width direction of the elastic bandage B, the tension of the thumb and the ball of the thumb does not increase. Further, since the resistance applying mechanism 3 has a function of adjusting the tension described later, for example, the pressing force of the elastic bandage B can be adjusted.
[Second Embodiment]

Next, the bandage wrapping tool 1A of the second embodiment will be described with reference to FIGS. 2 to 4. The second embodiment shows a specific example of the first embodiment. In the bandage wrapping tool 1A of the second embodiment, the same reference reference numerals are given to the parts having the same configuration as the bandage wrapping tool 1 of the first embodiment, the detailed description thereof is omitted, and the same names having different configurations are omitted. For the part of, add the subscript "A" to the reference code.

The bandage wrapping tool 1A of the second embodiment includes a housing 2A for accommodating the elastic bandage B and a resistance applying mechanism 3A for which the applied resistance force can be adjusted. More specifically, as shown in FIGS. 2 and 3, the bandage wrapping tool 1A includes a housing 2A including a case 21 and a lid 22, and a resistance applying mechanism including a resistor 31, an adjusting screw 32, and a support 33. It consists of 3A.

First, the case 21 and the lid 22 forming the housing 2A are made of a synthetic resin (for example, ABS resin or styrene resin) formed by injection molding. Then, the case 21 and the lid 22 store 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 port 21a of the case 21. An arc-shaped notch 21aa is provided in the center of the drawer port 21a so that the elastic bandage B can be easily picked up.

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

Next, the resistance applying mechanism 3A whose applied resistance force can be adjusted will be described. The resistor 31 is made of a synthetic resin formed by injection molding. Further, the resistor 31 has a shape of an arc pillar covering substantially half of the arc surface of the case 21, and is provided with key-shaped hooks 31a on the left and right sides of the rear end of the arc, and abuts on the front end of the arc with the elastic bandage B. The contact portion 31b is provided. Further, a rib 31c extending in the direction opposite to that of the case 21 is formed at the front end of the arc, and the rib 31c reinforces the contact portion 31b.

Further, the resistor 31 has a configuration in which the two hooks 31a are fitted into the two first hook holes 21b of the case 21, and the end portion of the resistor 31 on the contact portion 31b side covers the outlet 21a of the case 21. ing.

As a result, the elastic bandage B is sandwiched between the contact portion 31b of the resistor 31 and the arc surface in the vicinity of the outlet 21a of the case 21. Then, this pinching force becomes a resistance force for pulling the elastic bandage B, so that the elastic bandage B functions as a resistance imparting mechanism. The shape and material of the sandwiched portion may be partially changed so that this resistance force becomes the 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. Further, the resistor 31 can rotate with the hook 31a as a fulcrum. Therefore, in preparation for wrapping the elastic bandage B around the affected area, the bandage wrapping tool 1A can be easily used by rotating the resistor 31 while the resistor 31 is attached to the case 21 to widen the gap in which the elastic bandage B is sandwiched. The elastic bandage B can be pulled out slightly.

The adjusting screw 32 is for adjusting the resistance force applied by the resistance applying mechanism 3A, and is held by the support 33 in the case 21. The adjusting screw 32 is printed with a numerical value 32a as a scale on the head, and a non-slip knurl is engraved on the side surface of the head.

The support 33 is made of a synthetic resin formed by injection molding, and has the shape of an arc pillar covering a portion of the resistor 31 excluding the front end. Further, the support 33 has a screw hole 33a into which the adjusting screw 32 is screwed into the center of the arc on the front end side, key-shaped hooks 33b on the left and right sides of the rear end, and projects toward the case 21 side on the left and right ends of the front end. It is equipped with a guide 33c. A triangular index 33d is engraved on the support 33 in the vicinity of the screw hole 33a, and the resistance applying mechanism 3A sets the target scale from the numerical values 32a of the adjusting screw 32 according to the index 33d. It is configured to match.

The support 33 has a configuration in which two hooks 33b are fitted into the second hook hole 21c of the case 21 and two guides 33c are fitted into the guide hole 21d of the case 21 to cover a part of the resistor 31. It has become. Then, if the hook 33b is removed from the second hook hole 21c, the support 33 can be separated from the case 21. Further, the support 33 can rotate around the hook 33b. Therefore, in preparation for wrapping the elastic bandage B around the affected area, the bandage wrapping tool is prepared by rotating the support 33 while the resistor 31 and the support 33 are attached to the case 21 to widen the gap between the elastic bandage B. 1A can easily pull out the elastic bandage B slightly.

With such a configuration, in the resistance applying mechanism 3A, when the support 33 is pressed against the case 21 by the thumb and the ball of the thumb, the tip 32b of the screw of the adjusting screw 32 presses the resistor 31 against the case 21. The elastic bandage B is sandwiched between the contact portion 31b of the resistor 31 and the arc surface near the outlet 21a of the case 21. This pinching 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 by the contact portions 31b arranged in parallel over the entire width direction of the elastic bandage B on the arc surface near the outlet 21a, the resistance is uniform in the width direction of the elastic bandage B. It is pulled out by a uniform tension.

The magnitude of this resistance force by the resistance applying mechanism 3A is always constant because the gap of the contact portion 31b to the case 21 is kept constant depending on the position of the adjusting screw 32. Therefore, this resistance imparting mechanism 3A also functions as a mechanism for always imparting a constant resistance force. Then, by turning the adjusting screw 32, the position of the adjusting screw 32 (the depth at which the adjusting screw 32 is screwed into the support 33) is changed, and the magnitude of the resistance force thereof can be changed. As a result, the compression force can be appropriately changed depending on the site and purpose of wrapping the elastic bandage B. Therefore, the resistance applying mechanism 3A also functions as a mechanism capable of adjusting the applied resistance force.

The tension adjustment range of the adjusting screw 32 is set so that the pressing force is 26.7 hPs to 40 hPs (20 mmHg to 30 mmHg) at a predetermined number of turns. In this setting, it is necessary to obtain the relationship between the compressive force and the 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 squares method of regression analysis in statistics.

Further, although the resistor 31 and the support 33 are synthetic resins, they may be metals formed by sheet metal processing in order to further increase the strength. At this time, it is preferable that the end portion of the contact portion 31b of the resistor 31 is hemmed in order to prevent injury and further increase the strength. Further, the screw hole 33a of the support 33 is preferably screwed into a burring hole in order to extend the length of the female screw. Note that FIG. 2B shows a reference diagram when the bandage wrapping tool 1A is actually used. As shown in FIG. 2B, the bandage wrapping tool 1A is used by pressing the support 33 against the case 21 by the thumb and the ball of the thumb.
[Third Embodiment]

The bandage wrapping tool 1B of the third embodiment will be described with reference to FIGS. 5A and 5B. The bandage wrapping tool 1B of the third embodiment is obtained by removing the adjusting screw 32 and the support 33 from the bandage wrapping tool 1A of the second embodiment and adding the rolling mechanism 4. In the bandage wrapping tool 1B of the third embodiment, the same reference reference numerals are given to the parts having the same configuration as the bandage wrapping tool 1 of the second embodiment, the detailed description thereof is omitted, and the same names having different configurations are omitted. For the part of, add the subscript "B" to the reference code.

As shown in FIGS. 5A and 5B, the bandage wrapping tool 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, so that it is elastic. There is an effect that the force with which the bandage B is pulled out becomes uniform in the width direction of the elastic bandage B.

The rolling mechanism 4 of the third embodiment includes two rollers 41. The roller 41 has a cylindrical shape with a low height of synthetic resin formed by injection molding, and a bearing 41a is provided in the center. The bearing 41a of each roller 41 is fitted into a shaft 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), and the two rollers 41 are rotatably supported. ing.

As a result, in the bandage wrapping tool 1B, the arc surface of the roller 41 becomes a rolling surface 41b, and the rolling surface 41b can roll on the affected surface to wrap the elastic bandage B. At this time, the bandage wrapping tool 1B can roll the affected surface while keeping the angle at which the elastic bandage B is pulled out always constant with respect to the affected surface. Therefore, when the elastic bandage B is wrapped around the affected area, the work can be easily performed. In particular, until the first roll is made, the elastic bandage B will come off from the affected area unless the tip of the elastic bandage B is held by the other hand, so the bandage wrapping tool 1B must be made to go around with one hand. In this respect, the band wrapping tool 1B of the present embodiment can easily roll the affected surface, so that the first one wrapping operation is particularly easy. The rolling mechanism 4 of the third embodiment can also be applied to the first to second embodiments.

By using the bandage wrapping tool of the present invention as described above, the elastic bandage B can be easily wrapped around the affected area even if the person is not an expert. The specific structure of the resistance applying mechanism in the bandage wrapping tool of the present invention is not limited to the structure such as the resistance applying mechanism 3A shown in the second embodiment, and other structures may be adopted. can.

Further, even if the bandage wrapping tool of the present invention is used, it may be necessary to rewind the bandage wrapping tool in the middle of winding. In particular, in the bandage wrapping tool not provided with the rolling mechanism 4, the elastic bandage wrapping B may loosen because the bandage wrapping tool must be wound around the bandage wrapping tool with one hand for the first roll. Also, the patient may move during the bandaging operation. When the work using the bandage wrapping tool is interrupted in this way, the elastic bandage B is taken out from the bandage wrapping tool at one end, the elastic bandage B is wrapped in the original state, and the elastic bandage B is used as the bandage wrapping tool again. Must be contained. Therefore, it is more preferable that the bandage wrapping tool of the present invention is provided with a mechanism for winding the elastic bandage B while accommodating the elastic bandage B. As a result, even if the bandage wrapping work is interrupted, the elastic bandage B can be entangled without removing the elastic bandage B from the bandage wrapping tool.

Further, for example, when the elastic bandages B start to overlap at the beginning of the second roll, it may be necessary to pull the elastic bandages B slightly strongly so that the elastic bandages B are hard to come off. In such a case, the bandage wrapping tool may be provided with a stop mechanism for stopping the pulling out for a certain period of time so that the elastic bandage B is not pulled out even if the elastic bandage B is pulled out with a tension equal to or higher than a predetermined value. Further, it is preferable that this stop mechanism prevents an excessively large pulling force from being applied. For example, in addition to the usual resistance-imparting mechanism that imparts the pull-out resistance of R1 to the elastic bandage B, an auxiliary resistance-imparting mechanism (stop mechanism) that imparts the pull-out resistance of R2 is provided. If the auxiliary resistance applying mechanism is turned on only when the elastic bandage B overlaps a little in the second winding and the elastic bandage B is wound strongly with the pull-out resistance of R1 + R2, the elastic bandage B will not come off easily. 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.
Although the elastic bandage B is used for the bandage wrapping tool 1 of the above-described embodiment, even if it is used for a general bandage, it has the effect of wrapping the bandage with a predetermined tension.
