  FIG. 1 is a plan view showing a disinfecting aid 1 according to a first embodiment of the present invention. The antiseptic aid 1 is a medical article used for surgery and the like on arms and legs. The disinfection aid 1 is attached to the arm or leg when disinfecting the patient's arm or leg before surgery.

  The disinfection auxiliary tool 1 is a substantially sheet-like member. In the following description, the surface shown in FIG. 1 of the disinfection aid 1 will be referred to as "surface 21", and the surface opposite to surface 21 will be referred to as "back surface 22". The disinfecting aid 1 has an annular shape with a substantially circular opening 11 at the center in a plan view, and in the example shown in FIG. When the disinfection aid 1 is used, the arm or leg of the patient having a surgical site is inserted into the opening 11 from the back surface 22 side of the disinfection aid 1. The outer diameter of the disinfection aid 1 is, for example, 20 cm or more and 60 cm or less. The inside diameter of the disinfection aid 1 is, for example, 3 cm or more and 15 cm or less.

  The disinfection aid 1 comprises a central portion 12 and a peripheral portion 13. The central portion 12 is a stretchable sheet portion provided with the opening 11. In the example shown in FIG. 1, the shape of the outer edge 121 of the central portion 12 is substantially rectangular. The outer edge 121 of the central portion 12 is the inner edge of the peripheral portion 13 and is also the boundary between the central portion 12 and the peripheral portion 13. The central portion 12 is a portion having liquid impermeability or liquid repellency. The central portion 12 is formed of, for example, a rubber sheet. The peripheral portion 13 is a sheet portion that extends from the periphery of the central portion 12 in a direction away from the opening 11 (that is, radially outward around the center of the opening 11). In the example shown in FIG. 1, the shape of the outer edge 131 of the peripheral portion 13 (i.e., the outer edge of the disinfecting aid 1) is substantially circular with the opening 11 located at the central portion. The peripheral portion 13 is a portion having a liquid absorbing property. The peripheral portion 13 is formed of, for example, a non-woven fabric.

  For example, on the back surface 22 side of the non-woven fabric sheet having a substantially rectangular opening formed at the central portion, the sterilization assisting tool 1 is larger than the substantially rectangular opening and a substantially circular opening 11 is formed at the central portion It is formed by bonding a rubber sheet. Bonding of the non-woven fabric sheet and the rubber sheet is performed, for example, by a double-sided tape attached to the non-woven fabric sheet along the substantially rectangular opening (that is, along the outer edge 121 of the central portion 12).

  The periphery 13 includes a weakened line 14 leading from the outer edge 131 of the periphery 13 to the opening 11. In other words, the line of weakness 14 extends along the radial direction. In FIG. 1, the weakening line 14 is indicated by a thick broken line. The weakening line 14 is provided, for example, in the peripheral portion 13 between the outer edge 131 of the peripheral portion 13 and the outer edge 121 of the central portion 12 and is not provided in the central portion 12. The weakening line 14 is, for example, a perforation in which a plurality of small cuts or holes are intermittently arranged. The cuts or holes that constitute the perforations may or may not penetrate from the surface 21 to the back surface 22 of the disinfection aid 1. The weakening line 14 may be formed, for example, by covering a slit extending from the outer edge 131 of the peripheral portion 13 to the opening 11 with a linear cut film. The outer edge 131 of the peripheral portion 13 is provided with a notch 15 which is continuous with the weakening line 14 or located on the extension of the weakening line 14. In the example shown in FIG. 1, the notch 15 has a substantially triangular shape whose width in the circumferential direction gradually decreases as it approaches the weakening line 14 from the outer edge 131.

  In the example shown in FIG. 1, one weakening line 14 and one notch 15 are provided in the peripheral portion 13. The peripheral portion 13 may include a plurality of weakening lines 14 each directed from the outer edge 131 of the peripheral portion 13 to the opening 11. Further, the outer edge 131 of the peripheral portion 13 may be provided with a plurality of notches 15 which are respectively continuous with the plurality of weakening lines 14 or located on extensions of the plurality of weakening lines 14.

  Next, the pre-surgery disinfection of the arms and legs performed using the disinfection aid 1 will be described. In the following description, it is assumed that surgery is performed on the knee and below the leg. First, as shown in FIG. 2, a substantially cylindrical or substantially annular tourniquet 9, such as a tourniquet cuff, is attached to the thigh. At the time of wearing, pressurization of the thigh by the tourniquet 9 is not performed, and blood flow in the thigh is not stopped. Subsequently, the leg of the patient is inserted into the opening 11 of the disinfection aid 1 from the back surface 22 side of the disinfection aid 1. The central portion 12 of the disinfection aid 1 is located between the surgical site of the leg and the tourniquet 9 when the leg of the patient is inserted into the opening 11 and adheres to the entire circumference of the leg.

  In the example shown in FIG. 2, the disinfection aid 1 is disposed in the vicinity of the tourniquet 9 on the distal side of the tourniquet 9 of the leg. The antiseptic tool 1 has a substantially frustum shape that is convex toward the distal side (i.e., the distal end side) of the leg in a state of being attached to the leg. In the disinfection aid 1, for example, the ratio of the circumferential length of the inner edge 122 (that is, the edge of the opening 11) of the central portion 12 to the diameter of the opening 11 shown in FIG. By making it larger than the ratio of the perimeter of 131, the shape of the disinfection auxiliary tool 1 is made into a substantially frustum shape. As shown in FIG. 2, the distal portion of the tourniquet 9 is covered by the disinfection aid 1. In other words, the disinfection aid 1 is a tourniquet cover (for example, a tourniquet cover) covering at least a part of the tourniquet 9.

  Next, a disinfecting solution such as isozine solution is applied to the entire area on the peripheral side of the disinfection aid 1 of the leg. As described above, the central portion 12 of the disinfection aid 1 has liquid impermeability or liquid repellency and adheres to the entire circumference of the leg at its inner edge 122. For this reason, even when the disinfectant applied to the leg flows to the central side (that is, the base of the leg), it flows to the central side rather than the contact position between the central portion 12 of the disinfection aid 1 and the leg. Can be prevented. This can prevent the disinfectant from infiltrating between the tourniquet 9 and the skin. As a result, the skin under the tourniquet 9 can be prevented from causing chemical burn or contact with the antiseptic solution or causing pigmentation on the skin.

  In the disinfection auxiliary tool 1, as described above, the peripheral portion 13 has a liquid absorbing property. Therefore, even when the disinfectant applied to the leg flows to the central side and adheres to the surface 21 of the disinfectant 1, the disinfectant flows on the surface 21 and reaches the outer edge 131 of the disinfectant 1. Before this, the antiseptic solution can be absorbed and held at the peripheral portion 13. As a result, it can be suppressed that the disinfecting solution falls from the disinfecting aid 1 and adheres to the skin of the patient other than the disinfectant applying part.

  Further, as described above, the shape of the outer edge 131 of the peripheral portion 13 is substantially circular with the opening 11 positioned at the central portion. As described above, by matching the outer shape of the disinfection aid 1 to the shape of the tourniquet 9, covering at least the peripheral side portion of the tourniquet 9 with the disinfection aid 1 without excessively enlarging the disinfection aid 1 Can. As a result, it is possible to prevent the disinfectant from adhering to the tourniquet 9 while setting the disinfecting aid 1 to an appropriate size. Furthermore, since the disinfection aid 1 has a substantially frustum shape that is convex toward the distal end side of the leg, the disinfection aid 1 can be suppressed from being deformed by gravity or the like. Therefore, even when the disinfection aid 1 is located below the tourniquet 9, the disinfection aid 1 hangs down on the opposite side to the tourniquet 9, and the tourniquet 9 is exposed from the disinfection aid 1. It can be suppressed. As a result, adhesion of the antiseptic solution to the tourniquet 9 can be further suppressed.

  When the disinfectant applied to the leg dries, the disinfecting aid 1 is removed from the patient's leg. At the time of removal of the disinfection aid 1, for example, a nurse or the like grasps both sides in the circumferential direction of the notch 15 of the peripheral portion 13 and tears the disinfection aid 1 along the weakening line 14 from the notch 15 . As a result, the disinfecting aid 1 is removed from the leg of the patient's leg so as not to come into contact with the portion to which the disinfectant is applied.

  In the disinfection aid 1, the disinfection aid 1 can be easily torn (that is, broken) by the peripheral portion 13 including the weakened line 14 from the outer edge 131 to the opening 11. Thereby, the disinfection aid 1 can be easily removed from the patient. In addition, the weakening line 14 is provided only in the peripheral portion 13 and is not provided in the central portion 12, so that even if a cut or a hole forming the weakening line 14 penetrates the disinfection aid 1, the disinfection aid It is possible to prevent the antiseptic solution adhering to the central portion 12 of 1 from leaking out to the back surface 22 side and adhering to the tourniquet 9. Furthermore, the outer edge 131 of the peripheral portion 13 is provided with the notch 15 which is continuous with the weakening line 14 or located on the extension of the weakening line 14 so that the break start position of the disinfection aid 1 can be easily recognized. can do. Furthermore, tearing of the disinfection aid 1 along the weakened line 14 can be easily initiated. As a result, the disinfection aid 1 can be more easily removed from the patient.

  Similarly, when the patient's arm is disinfected, the patient's arm on which the tourniquet 9 is attached is inserted into the opening 11 of the disinfection aid 1 from the back surface 22 side. When the patient's arm is inserted into the opening 11, the central portion 12 of the disinfection aid 1 is located between the surgical site of the arm and the tourniquet 9, and adheres to the entire circumference of the arm. This can prevent the disinfectant from infiltrating between the tourniquet 9 and the skin as described above. Moreover, the disinfection auxiliary tool 1 has a substantially frustum shape that is convex toward the distal side (that is, the distal end side) of the arm in a state of being attached to the arm. Thereby, it can suppress that the disinfection auxiliary tool 1 deform | transforms by gravity etc. similarly to the above, As a result, it can suppress that a disinfection liquid adheres to the tourniquet 9. As shown in FIG.

  FIG. 3 is a plan view showing a disinfecting aid 1a according to a second embodiment of the present invention. The disinfection aid 1a has substantially the same structure as the disinfection aid 1 shown in FIG. 1 except that the peripheral part 13 includes the reinforcing part 16. In the following description, the same reference numerals as the configuration of the disinfection aid 1 are attached to the configuration corresponding to the disinfection aid 1 of the disinfection aid 1a.

  In the example shown in FIG. 3, the peripheral portion 13 includes a plurality of reinforcing portions 16. Each reinforcing portion 16 extends substantially straight from the outer edge 131 of the peripheral portion 13 to the opening 11. In other words, each reinforcing portion 16 extends substantially in the radial direction from the outer edge 131 of the peripheral portion 13. In the peripheral portion 13, for example, four reinforcing portions 16 are arranged at substantially equal angular intervals in the circumferential direction. The radially inner ends of the four reinforcing portions 16 are provided, for example, in the vicinity of the four corners of the substantially rectangular central portion 12. The reinforcement part 16 is a rib which protrudes on the surface 21 side of the disinfection auxiliary tool 1a. In the disinfection auxiliary tool 1a, a part of the peripheral portion 13 is folded in two along a folding line from the outer edge 131 to the opening 11, and the both sides of the folding line are joined to each other on the back surface 22 side , Reinforcement portion 16 is formed. In the central portion 12, due to the influence of the above-described bonding of the peripheral portion 13, a portion directed from the reinforcing portion 16 to the opening 11 is convexly projected to the surface 21 side.

  The method of using the disinfection aid 1a is the same as the method of using the disinfection aid 1 described above. In the state where the disinfection aid 1a is attached to the patient's arm or leg, the disinfection aid 1a is a substantially frustum that is convex toward the distal end side of the arm or leg, like the disinfection aid 1 shown in FIG. It is a state. Thereby, it can suppress that the disinfection auxiliary tool 1a deform | transforms by gravity etc.

  Moreover, in the disinfection auxiliary tool 1a, since the peripheral part 13 contains the above-mentioned reinforcement part 16, it can further suppress that a disinfection auxiliary tool 1a deform | transforms by gravity etc. Therefore, even when the disinfection aid 1a is located below the tourniquet 9 (see FIG. 2), the disinfection aid 1a hangs down on the opposite side to the tourniquet 9, and the tourniquet 9 is the disinfection aid 1a. It can control that it exposes from. As a result, adhesion of the antiseptic solution to the tourniquet 9 can be suppressed.

  In the disinfection auxiliary tool 1a, as described above, the rib which is the reinforcing portion 16 is formed by folding a part of the peripheral portion 13 in half along a folding line from the outer edge 131 to the opening 11 and joining them together. It is formed. Thereby, the reinforcing portion 16 can be easily provided in the peripheral portion 13.

  Various modifications can be made to the disinfection aid 1, 1a.

  For example, in the disinfection aid 1 a shown in FIG. 3, the reinforcing portion 16 may protrude to the back surface 22 side, or may project to both sides of the front surface 21 and the back surface 22. The reinforcing portion 16 does not necessarily have to be in the shape of a rib, and may have various structures having higher strength than the surrounding portions. For example, the reinforcing portion 16 may be a thick portion thicker than the surrounding portion in the peripheral portion 13. Moreover, in the disinfection auxiliary tool 1a, only one reinforcing part 16 may be provided in the peripheral part 13.

In the technology related to the present invention, when the disinfection aid 1, 1a is attached to the patient's arm or leg, the disinfection aid 1, 1a does not necessarily have to be attached to a position covering the tourniquet 9. . The disinfecting aid 1, 1a may be attached at a certain distance from the tourniquet 9 on the distal side (ie, the distal end) of the arm or leg.

  In the disinfection aid 1, 1a, the shape of the outer edge 131 of the peripheral portion 13, the shape of the outer edge 121 of the central portion 12, and the shape of the opening 11 may be variously changed. For example, the opening 11 may be substantially elliptical. When the outer edge 121 of the central portion 12 is a polygon formed of a plurality of straight lines, a double-sided tape or the like used for joining the central portion 12 and the peripheral portion 13 can be easily attached along the outer edge 121 Can.

  Moreover, the above-mentioned notch part 15 may be abbreviate | omitted, when the disinfection auxiliary tool 1 and 1a can be easily torn at the time of the removal from a patient. The weakening line 14 may also be omitted if it can be easily torn away at the time of removal from the patient.

  The peripheral portion 13 does not necessarily have to have a liquid absorbing property. The peripheral portion 13 may be made of, for example, the same material as the liquid-repellent or liquid-repellent central portion 12. In this case, in one sheet member having liquid impermeability or liquid repellency, a portion around the opening 11 may be the central portion 12 and a portion around the central portion 12 may be the peripheral portion 13.

  The configurations in the above embodiment and each modification may be combined as appropriate as long as no contradiction arises.
