Specification

Wound protector

Technical field

[0001] The present invention relates to a wound protector for protecting a wound formed in a living body, for example, by an incision or the like during surgery.

Background art

[0002] In general, for example, when an operation is performed on an organ of the chest or abdomen, a wound is formed by opening and opening the body surface side tissue force composed of skin, subcutaneous tissue or the like. Since this wound is opened with forceps, a chest opener, etc., the operator's hand or surgical instrument touches the cut surface of the tissue on the surface of the body, which becomes the edge of the wound, and this immediately causes the margin of the wound. May be damaged.

[0003] Therefore, conventionally, for example, a protective device as disclosed in Patent Document 1 is used to prevent the edge of the wound from being damaged. This protective device includes a protective part formed so as to cover the edge of the wound part, and an adhesive part that is attached to the surface of the skin. By attaching the protective device attachment to the surface of the skin, the protective part is prevented from being displaced.

[0004] In general, when performing the above-described operation, if the operator's sweating amount increases, the operation is hindered. Therefore, the room temperature in the operating room is about 20% that can suppress the operator's sweating amount. It is set to be between ° C and 22 ° C. In addition, fresh air is constantly flowing into the operating room for the operator.

Problems to be solved by the invention

[0005] However, as described above, air whose temperature is adjusted to a low level flows into the operating room, so the temperature of the air surrounding the patient is lower than the body temperature. As a result, the surface tissue of the patient and the tissue in the surgical field are cooled, the temperature of blood flowing through these tissues is lowered, and the patient's body temperature is deprived. When the patient's body temperature is deprived in this way, the energy in the patient's body becomes the body temperature. Since it is consumed and lost for maintenance, the body's energy necessary for recovery after surgery is reduced, and the postoperative recovery period is prolonged accordingly.

[0006] In addition, air that is colder than the body temperature hits the body surface during the operation as described above, so that the wound part is also cooled by this air, and the temperature of the wound part is higher than that at normal times. descend. If the temperature of the wound part is lowered in this way, the margins of the wound part become difficult to stick after surgery and the opening cannot be closed forcefully, and the immune function of the wound part is lowered and it becomes easy to infect pathogenic bacteria, etc. This also lengthens the post-operative recovery period.

[0007] The present invention has been made in view of such a point, and an object of the present invention is to maintain body temperature when the edge of a wound part is covered and protected by a protective device during surgery. The purpose is to reduce the energy consumed in the body and to reduce the temperature of the wound, thereby shortening the postoperative recovery period.

Means for solving the problem

[0008] In order to achieve the above object, according to the present invention, the margin of the wound portion is heated by the calorie temperature portion provided in the protective portion covering the margin of the wound portion.

[0018] In a fifth invention according to the fourth invention, the base material is formed in a plate shape having a mesh, and a heat storage agent is accommodated in the mesh.

According to this configuration, since the heat storage agent has fluidity, it tends to be biased in the accommodation space by its own weight. However, since the heat storage agent is accommodated in the mesh of the base material, It is possible to keep at least a part of the mesh. Thereby, it is suppressed that the thermal storage agent is largely biased in the accommodation space.

[0020] In a sixth invention according to the fourth invention, the housing space of the protection portion is formed by a resin sheet, and the heat storage agent is contained in the housing space between the base material and the sheet facing the base material. The structure is bonded so as to form a flow resistance portion that suppresses deviation due to fluid flow.

[0021] According to this configuration, the heat storage agent accommodated in the accommodation space is prevented from being largely biased in the accommodation space by the flow resistance portion.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0033] (Embodiment 1)

FIG. 1 shows a wound protector 1 according to Embodiment 1 of the present invention. As shown in FIG. 2, the protector 1 is formed when a chest or abdominal organ is operated on. This is to protect T. As shown in FIG. 3, the protector 1 includes a resin intermediate sheet 2. On one side surface of the intermediate sheet 2 (the upper surface in FIGS. 1 and 3), a first liquid absorbent material 3 and a first cloth material 4 for holding the first liquid absorbent material 3 between the intermediate sheet 2 are provided. And are provided.

On the other hand, on the other side surface of the intermediate sheet 2 (the lower surface in FIGS. 1 and 3), the base sheet 5 and the other side sheet 6 that holds the base material 5 between the intermediate sheet 2. And a second liquid absorbing material 7 and a second cloth material 8 for holding the second liquid absorbing material 7 between the other side sheet 6. Further, on the other side surface of the intermediate sheet 2, a pressure-sensitive adhesive 10 and a release sheet 11 covering the pressure-sensitive adhesive 10 are provided in a part away from the base material 5. [0035] As shown in Fig. 4, the intermediate sheet 2 is a rectangular translucent sheet made of polyethylene. The members constituting the intermediate sheet 2 are made impermeable to gas and liquid. The length of the intermediate sheet 2 in the longitudinal direction (left and right direction in FIGS. 1 and 4) is about 210 mm, and the dimension in the width direction (up and down direction in FIGS. 1 and 4) is about 150 mm. The shape of the four corners of the intermediate sheet 2 is composed of curves. The intermediate sheet 2 may be composed of a sheet such as polyurethane or polysalt bulb, or may be composed of a multilayer structure sheet in which these resin materials are laminated.

[0036] The first liquid-absorbing material 3 is made of a water-swellable fiber, and is formed in a substantially square plate shape having a side length of about 140 mm. As the water-swellable fiber, a lance seal manufactured by Toyobo Co., Ltd., which is composed of an inner layer made of acrylic fiber and an outer layer made of a water-absorbing resin, can be used. The water-swelling speed of this water-swellable fiber is the speed to absorb about 50% or more of the equilibrium water absorption in about 10 seconds when in contact with water. Further, after water absorption, the water-swellable fiber does not separate even if a certain pressure is applied, and has a property that it does not dissolve in water. Furthermore, the fiber diameter after water absorption of this water-swellable fiber expands to about 5 times or more of the fiber diameter before water absorption, while the fiber length dimension is maintained with acrylic fiber and is almost before and after water absorption. It does not change. In addition, since the fiber physical properties of the water-swellable fiber are maintained by acrylic fibers, the water-absorbing resin in the outer layer hardly deteriorates even when water is absorbed. The first liquid-absorbing material 3 may be composed of gauze made of cotton, rayon, or the like, a non-woven fabric obtained by mixing the above-mentioned water-swellable fibers with cotton or rayon, or water-swellable fibers with cotton or rayon. You may comprise by the laminated body which laminated | stacked.

[0037] The first cloth material 4 is made of a substantially square non-woven fabric having water permeability, and the length of one side is about 150 mm longer than the length of one side of the first liquid absorbent material 3. Has been. The non-woven fabric constituting the first fabric material 4 has a heat seal property that is welded to the resin material by applying heat. The first cloth material 4 is disposed on the side opposite to the intermediate sheet 2 of the first liquid absorbent material 3. The corresponding edge of the first fabric material 4 overlaps the edge of the intermediate sheet 2 on one side in the longitudinal direction. In this state, the peripheral edge of the first fabric material 4 extends over the entire circumference. 2 is welded. As a result, the first liquid absorbing material 3 is prevented from falling off between the intermediate sheet 2 and the first cloth material 4. [0038] The pressure-sensitive adhesive 10 is provided in the region of about 1Z4 from the other side of the intermediate sheet 2 toward the one side from the edge in the other side in the longitudinal direction (left side in FIGS. 1 and 4). This pressure-sensitive adhesive 10 is an acrylic, silicone, polyurethane, or rubber type that is generally used for application to human skin. Accordingly, a portion of about lZ 4 on the other side in the longitudinal direction of the intermediate sheet 2 is attached to the surface of the skin, and this portion and the pressure-sensitive adhesive 10 constitute the attaching portion 9 of the present invention.

[0039] The release sheet 11 is obtained by releasing a resin sheet, paper or the like with a silicone release agent or the like. When the release sheet 11 is made of a resin sheet, for example, a polyethylene terephthalate film or a polypropylene film can be used. On the other hand, when the release sheet 11 is made of a paper, a daracin paper, a clay coated paper, a laminated paper, etc. Can be used

[0040] The other side sheet 6 is made of the same material as the intermediate sheet 2, and has substantially the same shape as the first cloth material 4 in plan view. The edge of one side in the longitudinal direction of the intermediate sheet 2 and the corresponding edge of the other side sheet 6 overlap each other, and in this state, the peripheral edge of the other side sheet 6 extends to the intermediate sheet 2 over the entire circumference. It is welded liquid-tight with heat. Between the other side sheet 6 and the intermediate sheet 3, an accommodation space 15 for accommodating the base material 5 and the heat storage agent 13 which is a heating part of the present invention is formed. In other words, the size of the accommodation space 15 is set so as to extend in the vicinity of both edges in the width direction of the intermediate sheet 2 and in the vicinity of the adhesive 10 from one side in the longitudinal direction of the intermediate sheet 2 in plan view.

As shown in FIG. 5, the base material 5 is a combination of a large number of resin wire materials 20 in a net shape, and has substantially the same shape as the first liquid absorbing material 3 in plan view. Each wire 20 is composed of a resin material that does not break in the middle when bent, and has shape retention properties that retain the bent shape. As this resin material, for example, polyethylene, polypropylene, polyester, nylon and the like can be used. In this embodiment, polyethylene having the best shape retention among these resin materials is used. Les.

[0042] The base material 5 is provided with a plurality of bent portions 5a. The bent portions 5a have a shape extending linearly in the width direction of the base material 5 and are arranged with a space therebetween. The bent portion 5a is, for example, a portion that is weakened by being made thinner than other portions by heat. It is configured. As a result, when the protector 1 is used, the protector 1 can be easily bent along the bent portion 5a.

[0043] The heat storage agent 13 is made of a material having fluidity in a temperature range of at least 30 ° C to 37 ° C. Specifically, the heat storage agent 13 is prepared by adding water to a cellulose derivative that has been modified from plant cellulose extracted from plant power such as conifers and dissolved in water, and then kneaded into a predetermined container. It was obtained by irradiating with gamma rays and forming a soft jelly with fluidity. Therefore, the heat storage agent 13 is not toxic to humans, and the strength of the heat storage agent 13 is sterilized by gamma rays, so that high safety is ensured as a medical device. The amount of the heat storage agent 13 can be changed according to the surgical site where the protective device 1 is used, the surgical time, and the like. Further, the heat storage agent 13 can be composed of various materials having heat storage properties in addition to the plant cellulose derivative added with water.

[0044] The second liquid absorbing material 7 and the second cloth material 8 are the same as the first liquid absorbing material 3 and the first cloth material 4, respectively. That is, the peripheral edge portion of the second fabric material 8 is welded to the peripheral edge portion of the other side sheet 6 over the entire circumference, and the second liquid absorbent material is interposed between the other side sheet 6 and the second fabric material 8. 7 will not fall out.

That is, the protective device 1 includes the intermediate sheet 2, the first liquid absorbing material 3, the first cloth material 4, the base material 5, the other side sheet 6, the second liquid absorbing material 7, and the second cloth material 8. And a heat storage agent 13. In this protective device 1, the intermediate sheet 2 excluding about 1/4 of the other side in the longitudinal direction, the first liquid absorbent material 3, the first cloth material 4, the base material 5, the other side sheet 6, the second liquid absorbent The protective part 21 of the present invention is constituted by the material 7 and the second cloth material 8, and the protective part 21 is continuous with the sticking part 9.

[0046] Although not shown, the protective device 1 is stored in a transparent storage bag made of a resin film having no moisture permeability and stored together with sterilization paper. Yes. For this reason, it is possible to prevent the first liquid-absorbing material 3 and the second liquid-absorbing material 7 from absorbing moisture in the air during storage and reducing the liquid-absorbing ability.

[0047] Next, a procedure for using the protective device 1 configured as described above will be described. Protective equipment 1 is placed in a heater (not shown) before use. Heat is stored in the heat storage agent 13 in the heater so that the temperature of the heat storage agent 13 is in the range of 30 ° C. to 37 ° C. It should be noted that fresh air adjusted to about 20 ° C to 22 ° C flows into the operating room where the protective device 1 is used.

Then, as shown in FIG. 2, after opening the wound part T of the patient, the protective part 21 is directed so that the second cloth material 8 of the holding part 21 is on the wound part T side. The wound part T is bent along the edge, and the protective part 21 covers the edge of the wound part T. Thereafter, the release sheet 11 is peeled off with a pressure-sensitive adhesive 10 to bring the sticking part 9 into close contact with the skin surface. This makes it difficult for the protective portion 21 to shift the marginal force of the wound portion T, and prevents the operator's hand, instrument, etc. from coming into contact with the margin of the wound portion T. In addition, by covering the edge of the wound part T with the protective part 21 in this manner, pathogenic bacteria and the like are less likely to adhere to the wound part T, and the risk of infection is reduced. At this time, the periphery of the wound part T is also covered by the protection part 21.

[0049] In addition, blood that bleeds from the wound part T during surgery, exuded body fluid, and the like pass through the second cloth material 8 and are absorbed by the second liquid absorbing material 7. In addition, blood, body fluid, and the like from the inside of the operative field are absorbed by the second liquid absorbent material 7 and are also absorbed by the first liquid absorbent material 3 after passing through the first cloth material 4.

[0050] Further, the heat of the heat storage agent 13 is transmitted to the edge of the wound portion T through the other side sheet 6, the second liquid absorbent material 7, and the second cloth material 8, and is also transmitted to the periphery of the edge. The edge of the wound T and the vicinity thereof are heated at a temperature higher than the temperature of the air surrounding the patient. As a result, blood flowing in and around the margin of the wound T is warmed and circulated in the body during surgery, so it is possible to reduce the amount of energy used to maintain the body temperature. . In addition, by heating the margin of the wound part T, the wound part after the operation becomes easy to stick together, and the decrease in the immune function is suppressed, making it difficult to infect pathogenic bacteria.

[0051] In addition, since the base material 5 has shape retentivity, the protective part 21 is shaped along the edge of the wound part T and is in close contact with the edge. At this time, the heat storage agent 13 flows in the accommodation space 15 and has a shape along the edge of the wound portion T.

[0052] Furthermore, when the protective part 21 is bent as described above so as to cover the edge of the wound part T, the heat storage agent 13 tends to be biased downward in the accommodation space 15 due to its own weight. Is contained in the mesh of the base material 5, so that at least a part of the heat storage agent 13 remains in the mesh. Thereby, it is suppressed that the heat storage agent 13 is largely biased to the lower side of the accommodation space 15. [0053] Therefore, according to the wound protector 1 according to this embodiment, the heat storage agent 13 is stored in the storage space 15 of the protection unit 21 that protects the edge of the wound portion T, and the heat storage agent 13 The edge of the wound T can be heated. As a result, the amount of energy consumed in the body can be reduced, the temperature of the wound T can be prevented from decreasing, and the postoperative recovery period can be shortened.

[0054] Since the heat storage agent 13 having fluidity and the base material 5 that retains the shape of the protection unit 21 are stored in the storage space 15 of the protection unit 21, the heat storage agent 13 is placed along the edge of the wound portion T. It can be shaped. In addition, since the heat storage agent 13 is accommodated in the mesh of the base material 5, it is possible to suppress the heat storage agent 13 from being largely biased in the accommodation space 15. By these things, the edge of the wound part T covered with the protection part 21 and its vicinity can be heated substantially uniformly.

[0055] (Embodiment 2)

6 and 7 show a wound protector 1 according to Embodiment 2 of the present invention. In the protector 1 of this embodiment 2, the heating part and the base material 5 are different from those of the protector 1 of embodiment 1 only, and the other parts are the same. The description will be omitted with reference numerals, and different parts will be described in detail.

[0056] That is, in this embodiment, the heating unit is composed of a heating element that generates heat when electric power is supplied, and specifically, a metal wire 30 such as a nichrome wire. The substrate 5 is made of a thin metal plate and is accommodated in the accommodating space 15 of the protection part 21. This base material 5 can be easily bent by hand, and has a shape-retaining property to hold the bent shape. That is, the shape of the protection part 21 is maintained by the deformation of the base material 5.

As shown in FIG. 7, the intermediate portion of the metal wire 30 is bent and pasted so as to cover substantially the entire surface of the base sheet 5 on the other side sheet 6 side. Both ends of the metal wire 30 extend from the accommodation space 15 to the outside. Although not shown in the drawing, a temperature sensor such as a thermocouple for detecting the temperature state of the metal wire 30 is provided on the base material 5, and the signal wire of this temperature sensor extends from the housing space 15 to the outside. .

A power supply device 31 is connected to both ends of the metal wire 30. The supply device 31 includes a temperature adjustment unit 32, a control unit 33, and a power supply unit 34. Temperature controller 3 2 is for adjusting the heat generation temperature of the metal wire 30 so that the operator can set the heat generation temperature range of the metal wire 30 to 30 ° C or more and 37 ° C or less, for example. There is. The control unit 33 is connected to the signal line of the temperature sensor. The control unit 33 controls the power supply unit 34 so that the temperature of the substrate 5 becomes the temperature set by the temperature adjustment unit 32.

Therefore, according to the wound protector 1 according to Embodiment 2, power is supplied from the supply device 31 to the metal wire 30 and the edge of the wound portion T is covered by the protector 21. Similarly to the first embodiment, the edge of the wound portion T and the vicinity thereof can be heated. As a result, the postoperative recovery period can be shortened.

[0060] Since the metal wire 30 is heated by supplying electric power, when the operation time is prolonged, the edge of the wound T and the vicinity thereof are heated at a stable temperature until the end of the operation. The power to do S.

In Embodiment 2, the base material 5 may be made of a resin material other than the metal thin plate, for example.

[0062] (Embodiment 3)

FIG. 8 shows a wound protector 1 according to Embodiment 3 of the present invention. The protective device 1 of the third embodiment is different from the protective device 1 of the first embodiment only in that a part of the intermediate sheet 2 and a part of the other side sheet 6 are bonded to the base material 5, and the other parts. In the following, the same parts are denoted by the same reference numerals, description thereof is omitted, and different parts are described in detail.

That is, welded portions 40a and 40b extending linearly in the width direction of the intermediate sheet 2 are spaced apart in the longitudinal direction of the intermediate sheet 2 at a portion facing the base material 5 of the intermediate sheet 2. It is provided. These welds 40a and 40b are welded to the base material 5 by heat. The lengths of the welded portions 40a and 40b are set to be shorter than the dimension of the intermediate sheet 2 in the width direction. The welded portion 40a extends from one end in the width direction of the intermediate sheet 2 (upper side in FIG. 8) toward the other side (lower side in FIG. 8). Also, the welded portion 40b adjacent to the welded portion 40a extends from the other end in the width direction of the intermediate sheet 2 toward one side. Although not shown, the other side sheet 6 is also provided with a similar welded portion.

[0064] By the welded portions 40a and 40b, a bent flow path 41 is formed in the accommodation space 15, and the heat storage agent 13 flows in the flow path 41. As a result, the heat storage agent 13 It becomes difficult to flow inside, and it is suppressed that it is biased to a part of the accommodation space 15. That is, the flow path 41 formed by the welded portions 40a and 40b is the flow resistance portion of the present invention. Note that a welded portion may be provided only on one of the intermediate sheet 2 and the other side sheet 6.

Therefore, according to the wound protector 1 according to Embodiment 3, the same operational effects as in Embodiment 1 can be obtained.

[0066] Further, since the welded portion 40a, 40b of the intermediate sheet 2 and the welded portion of the other side sheet 6 form a bent passage 41 in the accommodation space 15, the heat storage agent 13 accommodated in the accommodation space 15 is caused by its own weight. It is possible to suppress the downward bias of the accommodation space 15. Thereby, the edge of the wound part T covered with the protection part 21 and its vicinity can be heated substantially uniformly.

[0067] (Embodiment 4)

FIG. 9 shows a use state of the protector 100 for the wound part according to Embodiment 4 of the present invention. The protector 1 of the fourth embodiment is configured by integrating two component members 100a and 100b configured in the same manner as the protector 1 of the first embodiment.

The connecting portion 101 is made of a resin sheet that does not allow gas and liquid to pass through, and is bonded to the edge of the intermediate sheet 2 between the two constituent members 100a and 100b. The size of the connecting portion 101 is set to be large enough to cover the edge of the wound portion T.

[0069] When using the protector 100 of the fourth embodiment, the one component member 100a and the other component member 100b are affixed to the skin, and the connecting portion 101 is disposed between the two component members 100a and 100b. The wound part T is pressed against the wound part T, and the wound part T is covered with the connecting part 101.

[0070] Also with the wound protector 100 according to the fourth embodiment, the same effects as those of the first embodiment can be obtained.

[0071] In addition, the protector 100 of the fourth embodiment can protect the peripheral edge portion of the wound portion T over the entire circumference by providing the connecting portion 101.
