Description

[Technical field]

[0001] The present invention relates to a treatment bag-like body that is attached to a patient suffering from an infectious disease, for example, to perform treatment. [Background technology]

[0002] Conventionally, various measures have been taken with the aim of preventing secondary infections caused by contact with patients infected with bacteria or viruses, etc. For example, JP 2010-269121 A (Patent Document 1) proposes a ventilation booth with the aim of preventing hospital infections caused by airborne microorganisms such as airborne bacteria and airborne viruses released from infected or suspected infected patients.

[0003] The ventilation booth described in Patent Document 1 includes an enclosure that covers the head area of ​​the patient, a frame assembly that supports the enclosure, and a blower that can suck air inside the booth. This blower includes a filter that purifies the air, and as the air inside the booth is ventilated, airborne bacteria and viruses released by the patient are captured by the filter, preventing secondary infection (hospital infection). [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2010-269121 A Summary of the Invention [Problem to be solved by the invention]

[0005] However, while the ventilation booth described in Patent Document 1 can prevent secondary infection of other hospitalized patients, it cannot prevent secondary infection of medical staff because doctors and nurses who treat patients must enter the booth. In particular, when performing procedures such as intubation and extubation of the patient's trachea, medical staff are at high risk of becoming infected with bacteria or viruses carried by the patient.

[0006] In addition, since the ventilation booth described in Patent Document 1 is equipped with an enclosure, a frame assembly, a blower, etc., it tends to be relatively large, and there was a demand for a booth that is superior in terms of transportation, storage, handling, cost, etc.

[0007] The problem to be solved by the present invention is to provide a simple and novel bag-like body for treatment that can prevent infection in medical personnel during treatment. [Means for solving the problem]

[0008] The following describes preferred embodiments for understanding the present invention, but the embodiments described below are merely illustrative and may be combined with one another as appropriate, and the multiple components described in each embodiment may be recognized and used independently as far as possible, and may also be combined with any of the components described in another embodiment as appropriate. As a result, the present invention is not limited to the embodiments described below, and various other embodiments may be realized.

[0009] The first aspect is a treatment bag-like body that forms an internal space capable of accommodating a human head and through which the interior can be observed, has an opening large enough for the head to pass through, and at least a portion of the opening is provided with a first constriction sealing portion and a second constriction sealing portion as constriction sealing portions for narrowing the opening amount, thereby enabling a two-stage sealing operation.

[0010] According to the treatment bag of this embodiment, by placing it over the patient's head and narrowing the opening during treatment, it is possible to prevent the spread of bacteria and viruses carried by the patient to the outside, thereby preventing infection of medical staff. In particular, since this embodiment only requires a size large enough to accommodate the head of a human body, it does not need to be large like a ventilation booth with a conventional structure, and is easy to transport, store, and handle, and the manufacturing cost can be reduced. In addition, by using a two-stage sealing structure at the opening, it is possible to perform temporary and permanent sealing at the opening, or to seal the opening more reliably.

[0011] In the second aspect, in the treatment bag-like body according to the first aspect, the first constriction sealing portion is a temporary fastening portion that can be repeatedly fastened, while the second constriction sealing portion is a permanent fastening portion having a higher degree of fastening or adhesion than the first constriction sealing portion.

[0012] According to the treatment bag of this embodiment, the opening of the opening portion can be narrowed and then temporarily secured by the first constriction sealing part, and then permanently secured by the second constriction sealing part. In particular, since the temporary securing by the first constriction sealing part can be repeatedly performed, it is possible to perform the temporary securing again and again as necessary to accurately determine the position, and then perform the permanent securing to perform reliable constriction and sealing.

[0013] The third aspect is a treatment bag-like body that forms an internal space capable of accommodating a human head and through which the interior can be observed, and in an opening portion large enough for the head to pass through, a slit-like cut is provided extending from the opening edge extending in the circumferential direction toward the bottom of the bag, and the portion where the cut is formed is provided with a closing seal portion that closes the cut by fixing together both circumferential side edges that sandwich the cut.

[0014] According to the present embodiment of the treatment bag-like body, the opening can be opened wide by the slit-like cut when the head of the human body is placed inside the bag-like body. After the head of the human body is placed inside the bag-like body, the tools required for treatment can be easily inserted and removed from the bag-like body through the cut.

[0015] In a fourth aspect, in the treatment bag-like body according to the third aspect, the closure seal portion includes a first closure seal portion consisting of a temporary fastening portion capable of being repeatedly fastened, and a second closure seal portion consisting of a permanent fastening portion having a higher degree of fastening or adhesion than the first closure seal portion.

[0016] According to the present embodiment of the treatment bag, the incision can be closed reliably by, for example, redoing the temporary fastening with the first closure seal as necessary and then final fastening in an accurately positioned state. In addition, when the temporary fastening is performed with the first closure seal, the incision can be repeatedly opened and necessary treatment tools can be inserted into the bag each time.

[0017] The fifth aspect is a treatment bag-like body relating to the third or fourth aspect, which has a bag-like main body in which a lower sheet-like portion and an upper sheet-like portion overlap each other and are connected around the periphery except for the opening portion, and the notch is provided on the opening edge of the lower sheet-like portion at a position away from the center in the opening width direction toward one end side.

[0018] According to this embodiment of the treatment bag-like body, a notch is provided at a position away from the center of the opening width direction toward one end of the opening, so that, for example, a notch can be provided in the bag-like body at a position away from the location where the human head is accommodated toward one end of the bag-like body.

[0019] The sixth aspect is a treatment bag-like body that forms an internal space capable of accommodating a human head and allows the interior to be observed, and in the opening portion formed in a size that allows the head to pass through, an upper sheet-like portion located in front of the head of a human body in a supine position is provided with a fixing portion that holds the opening side end portions of the upper sheet-like portion in an overlapping state on both sides in the opening width direction so that the upper sheet-like portion is folded in a mountain fold at the middle part in the opening width direction and maintained in a shape that protrudes toward the surface.

[0020] According to the treatment bag of this aspect, the strength of the bag is increased at the area where the upper sheet-like portion is held in an overlapping state by the fastening portion, and the bag is held in a protruding shape toward the surface, so that a tent-shaped space within the bag can be formed in front of the face of a patient in a supine position. This space within the bag can be used to secure a treatment area, for example, when inserting or extubating a tube into the patient's trachea.

[0021] In a seventh aspect, in the treatment bag according to the sixth aspect, a hook-and-loop fastener is provided on the fastening portion.

[0022] According to the treatment bag of this embodiment, the fastening by the hook-and-loop fastener can be redone as necessary, and the bag-shaped space formed in front of the patient's face can be adjusted to the desired shape, etc. Also, the strength of the hook-and-loop fastener members can be used to reinforce the bag-shaped body, which can improve the workability of the folding operation and stably maintain the mountain-folded state.

[0023] The eighth aspect is a treatment bag-like body that forms an internal space capable of accommodating the head of a human body and allows the interior to be observed, and has a glove-like portion extending from the surface of the bag-like body toward the internal space, and an arm insertion opening formed on the surface of the bag-like body, which serves as an opening for inserting the arm into the glove-like portion, has a ring body harder than the bag-like body attached around it.

[0024] According to the treatment bag of this embodiment, even if the bag body is soft, the arm-insertion opening is maintained in a ring shape, making it easy for the practitioner to insert his / her arm into the glove-like portion.

[0025] In a ninth aspect, in the treatment bag-like body of the eighth aspect, the ring body is fixedly attached to the arm-insertion opening of the bag-like main body, and the glove-like portion formed separately from the bag-like main body is attached to the ring body at the opening end through which the arm is inserted.

[0026] According to the present embodiment of the treatment bag-like body, the glove-like portion formed separately from the bag-like body can be used, which facilitates manufacturing. In addition, the design freedom of the bag-like body and the glove-like portion can be improved.

[0027] In the tenth aspect, in the treatment bag-like body of the ninth aspect, the opening end of the glove-like portion is an elastic opening end whose opening is elastically narrowed to a size smaller than the size of the ring body, and the elastic opening end is elastically hooked and attached to the ring body.

[0028] According to the treatment bag of this aspect, the glove-like portion can be easily attached to the ring body of the bag-like main body.

[0029] The eleventh aspect is a treatment bag-like body that forms an internal space capable of accommodating a human head, and whose interior can be observed, and has a lower sheet-like portion and an upper sheet-like portion that constitute a bag-like main body having an opening large enough for the head to pass through, and the upper sheet-like portion is provided with a glove-like portion extending from the surface of the bag-like main body toward the internal space, while a hanging portion that bends downward and hangs down is set on the bottom side of the opening of the glove-like portion in the upper sheet-like portion, and on the bottom side of the head accommodation area in the lower sheet-like portion, and these hanging portions of the upper sheet-like portion and lower sheet-like portion are configured to form a pocket-like portion in the internal space, located on the bottom side of the bag-like main body, when a practitioner inserts his or her hand into the glove-like portion for treatment.

[0030] According to the treatment bag of this embodiment, for example, tools necessary for treatment can be stored in the pocket-like portion beforehand, and the tools can be taken out from the pocket-like portion and used during treatment. Also, by storing items that are temporarily or ultimately no longer needed during treatment in the pocket-like portion, the items are less likely to get in the way of treatment.

[0031] The twelfth aspect is a treatment bag-like body that forms an internal space capable of accommodating a human head and whose interior can be observed, wherein the set position of the center of the body axis of the human head accommodated in the internal space is offset from the center to one side in the width direction of the internal space, and a service space is provided on the other side of the internal space from the center in the width direction, positioned to the side of the accommodated human head.

[0032] According to the treatment bag-like body of this embodiment, by providing a service space, for example in cases where various devices for treating the patient are placed on either the left or right side of the patient, it is possible to secure space for handling tubes for connecting the patient to the devices, to use the service space to place treatment tools, and to efficiently secure space for the practitioner to carry out treatment work.

[0033] The thirteenth aspect is a treatment bag-like body that forms an internal space capable of accommodating a human head and allows the interior to be observed, in which a bag-like body having an opening large enough for the head to pass through is provided with a tube insertion portion and a reinforcing member is attached to the outer periphery of the tube insertion portion, allowing a tube to be inserted by breaking through the tube insertion portion.

[0034] According to this embodiment of the treatment bag-like body, the strength of the outer periphery of the tube insertion portion can be improved by the reinforcing member, making it easier to insert the tube into the tube insertion portion in the bag-like main body and preventing problems such as the area around the tube insertion point tearing and opening.

[0035] In a fourteenth aspect, in the treatment bag-like body of the thirteenth aspect, the reinforcing member is provided with an insertion hole, and the tube insertion portion made of the bag-like main body and / or a separate sheet is overlapped so as to cover the insertion hole, and a fragile portion such as a perforation is formed in the tube insertion portion.

[0036] According to the treatment bag of this embodiment, the weak part is provided in the tube insertion part, which makes it easier to insert the tube. In particular, since the weak part is formed of perforations or the like, the tube insertion part after the tube is inserted remains in a pleated shape and contacts the surface of the tube, which makes it possible to maintain or improve the closure of the tube insertion part.

[0037] In a fifteenth aspect, in the treatment bag-like body according to the first to fourteenth aspects, an opening portion formed to a size allowing the head to pass therethrough is provided with a positioning adhesive surface that can be attached to the surface of the human body.

[0038] According to the treatment bag of this embodiment, by fixing the opening of the bag to the surface of the human body with the positioning adhesive surface, it is possible to prevent the position of the bag from shifting from the human body to the bag, and to reduce the gap between the opening and the human body, thereby preventing the spread of bacteria or viruses to the outside through the gap. Note that the positioning adhesive surface of this embodiment can also constitute, for example, the second constriction sealing portion in the first embodiment. Effect of the Invention

[0039] According to the present invention, it is possible to provide a simple and novel treatment bag-like body that can prevent infection in medical personnel during treatment. [Brief description of the drawings]

[0041] In order to clarify the present invention more specifically, embodiments of the present invention will be described in detail below with reference to the drawings.

[0042] First, Fig. 1 shows a treatment bag 10 as one embodiment of the present invention. This treatment bag 10 is used when performing treatment such as intubation and extubation of a respirator tube or tracheal tube on a patient who is infected with or suspected of being infected with an infectious disease, and is intended to prevent secondary infection from the patient to a medical worker. In the following description, the front-rear direction is the bottom-up direction in Fig. 1, the front is the bottom side in Fig. 1 where the patient is located with respect to the treatment bag 10, and the rear is the top side in Fig. 1 where the medical worker is located with respect to the treatment bag 10. In addition, the left-right direction is the left-right direction in Fig. 1.

[0043] More specifically, the treatment bag 10 has a bag-shaped main body 12 that is rectangular in plan view as a whole. That is, as shown in Figs. 2(a) and (b), the bag-shaped main body 12 has an upper sheet-shaped portion 14 and a lower sheet-shaped portion 16 that overlap each other. The upper sheet-shaped portion 14 and the lower sheet-shaped portion 16 are connected on three sides except for an opening portion 18. In this embodiment, the opening portion 18 is provided in the front of the treatment bag 10 (bag-shaped main body 12), and the upper sheet-shaped portion 14 and the lower sheet-shaped portion 16 are connected on three sides, the rear and both the left and right sides. Therefore, the rear side of the treatment bag 10 (bag-shaped main body 12) is the bottom side of the bag. In addition, Figure 2(a) shows the outer surface side of the upper sheet-like portion 14 (the side that will become the outer surface when the bag-shaped main body 12 is constructed), and Figure 2(b) shows the inner surface side of the lower sheet-like portion 16 (the side that will become the inner surface when the bag-shaped main body 12 is constructed).

[0044] The treatment bag 10 (bag-shaped main body 12) is made of soft resin such as polyethylene, and is preferably made of a transparent synthetic resin sheet. The treatment bag 10 (bag-shaped main body 12) may be colorless and transparent or colored and may have a visible light transmittance of 80% or more, so long as the inside can be observed. As shown in FIG. 8, which will be described later, the internal space 20 (between the upper sheet-shaped part 14 and the lower sheet-shaped part 16 in the inflated state) in the treatment bag 10 (bag-shaped main body 12) is large enough to accommodate the head of a human body (patient). The opening 18 is large enough for the patient's head to pass through, and the patient's head is accommodated in the internal space 20 through the opening 18.

[0045] A hook-and-loop fastener 22 and a double-sided tape 24 are provided on the inner surface of the opening 18 of the treatment bag 10 (bag-like main body 12). The hook-and-loop fastener 22 and the double-sided tape 24 may be conventionally known, that is, the hook-and-loop fastener 22 has, for example, a first hook-and-loop fastener 22a raised in a hook shape and a second hook-and-loop fastener 22b raised in a loop shape that are fixed to each other. The double-sided tape 24 is configured such that the inner surface of the bag-like main body 12 and a release sheet are attached to both sides of the adhesive layer, that is, the release sheet is attached to the inner surface of the bag-like main body 12 via the adhesive layer. The adhesive surface is exposed by peeling off the release sheet. Instead of the release sheet, an adhesive bandage having a release sheet attached to one side having adhesiveness may be attached to the adhesive layer on the non-adhesive side, and the adhesive surface of the adhesive bandage may be exposed by peeling off the release sheet. This can improve breathability and prevent skin rashes of the patient. However, instead of the double-sided tape 24, it is also possible to use an adhesive bandage having adhesive properties on both sides, and a release sheet may be attached to such an adhesive bandage.

[0046] In this embodiment, as described later, a plurality of double-sided tapes 24, i.e., a plurality of release sheets, are provided, and for example, one end of each of these release sheets may be marked with numbers indicating the order in which they should be removed or arrows indicating the direction in which they should be removed. Also, a tab may be provided at one end of each of these release sheets to make them easier to remove.

[0047] Furthermore, in this embodiment, a first hook-and-loop fastener 22a and a second hook-and-loop fastener 22b are fixed to each other by adhesion or the like at a position spaced some distance rearward from the front edge that becomes the opening edge on the inner surface side of the upper sheet-like portion 14. In particular, in this embodiment, the first hook-and-loop fastener 22a and the second hook-and-loop fastener 22b are each formed with a left-and-right dimension that is less than half the left-and-right dimension of the bag-shaped main body 12 (upper sheet-like portion 14), and are provided adjacent to each other in the left-and-right direction.

[0048] The left-right center of the arrangement area of ​​the first and second hook-and-loop fasteners 22a, 22b is set to be biased to the right of the left-right center of the upper sheet-like portion 14. In short, in the upper sheet-like portion 14, the first hook-and-loop fastener 22a is provided in the right-side area, the second hook-and-loop fastener 22b is provided in the left-right center area, and an area where neither the first hook-and-loop fastener 22a nor the second hook-and-loop fastener 22b is provided is provided on the left-side. Note that the first hook-and-loop fastener 22a and the second hook-and-loop fastener 22b are both formed in a substantially rectangular band shape, but in this embodiment, the width dimension of the first hook-and-loop fastener 22a is smaller than the width dimension (front-rear dimension) of the second hook-and-loop fastener 22b. This allows a certain degree of misalignment between the first and second hook-and-loop fasteners 22a and 22b when the first and second hook-and-loop fasteners 22a and 22b are fixed together, and makes it easier to peel the first and second hook-and-loop fasteners 22a and 22b apart. Furthermore, since the hook-shaped raised first hook-and-loop fasteners 22a are formed narrow, the risk of the first hook-and-loop fasteners 22a coming into contact with the patient and causing pain to the patient can be reduced.

[0049] In this embodiment, three double-sided tapes 24 (i.e., first to third double-sided tapes 24a to 24c) are provided around the periphery of the opening 18 of the bag-shaped main body 12. These first to third double-sided tapes 24a to 24c are provided on the inner surface side of the lower sheet-like portion 16. The second double-sided tape 24b is provided across the upper sheet-like portion 14 and the lower sheet-like portion 16 so as to be folded back at the right end of the bag-shaped main body 12, and is provided over the right part of the lower sheet-like portion 16 and approximately the entire length of the upper sheet-like portion 14 in the left-right direction.

[0050] In particular, in this embodiment, the left-right center of the area where the first to third double-sided tapes 24a to 24c are provided in the lower sheet-like portion 16 is set to be biased to the right of the left-right center of the lower sheet-like portion 16, and there is an area to the left of the third double-sided tape 24c where no double-sided tape is provided. Furthermore, the first to third double-sided tapes 24a to 24c are provided at approximately equal positions in the front-rear direction in the bag-shaped main body 12.

[0051] Further, in the lower sheet-like portion 16, a slit-like cut 28 is provided to the left of the third double-sided tape 24c, extending from the front edge, which is the opening edge, toward the rear, which is the bottom side of the bag. In this embodiment, the cut 28 is provided in the opening portion 18 of the bag-shaped main body 12, between the left end, which is one end in the opening width direction, and the left-right center. That is, the cut 28 is provided at a position away from the left-right center toward the left end, and at a position away from the left end toward the center. The cut 28 extends substantially straight with a certain dimension in the front-rear direction, and is formed with a front-rear dimension that is, for example, about 1 / 3 of the front-rear dimension of the lower sheet-like portion 16.

[0052] The lower sheet-like portion 16 is provided with a first hook-and-loop fastener 30a and a second hook-and-loop fastener 30b, which are fixed to each other, on both sides of the cut 28 in the left-right direction. The first and second hook-and-loop fasteners 30a, 30b extend from the front edge of the lower sheet-like portion 16 to the rear of the cut 28, and the rear ends of the first and second hook-and-loop fasteners 30a, 30b have portions that extend in the left-right direction. In this embodiment, the first hook-and-loop fastener 30a, which is raised in a hook shape, is provided to the left of the cut 28 at a certain distance, and the second hook-and-loop fastener 30b, which is raised in a loop shape, is provided to the right of the cut 28 at a certain distance. In particular, in this embodiment, in the pre-use state shown in FIG. 1, the second hook-and-loop fastener 22b provided on the upper sheet-like portion 14 and the second hook-and-loop fastener 30b provided on the lower sheet-like portion 16 are partially overlapped in the up-down direction. Here, since the hook-and-loop fasteners that overlap in the vertical direction are both second hook-and-loop fasteners 22b, 30b that are raised in a loop shape, it is possible to prevent the upper and lower hook-and-loop fasteners (second hook-and-loop fasteners 22b, 30b) from unintentionally adhering to each other before use.

[0053] In this embodiment, the first hook-and-loop fastener 30a is formed with a smaller width than the second hook-and-loop fastener 30b. This allows a certain degree of misalignment between the first hook-and-loop fastener 30a and the second hook-and-loop fastener 30b when the first hook-and-loop fastener 30a and the second hook-and-loop fastener 30b are fixed together, and makes it easier to peel the first hook-and-loop fastener 30a and the second hook-and-loop fastener 30b apart. Furthermore, since the hook-and-loop fastener 30a is formed with a narrow width, the risk of the first hook-and-loop fastener 30a coming into contact with the patient and causing pain to the patient can be reduced. In particular, by providing the hook-and-loop fastener 30a on the outside (left side) and the loop-and-loop fastener 30b on the patient side (center side), the risk of the first hook-and-loop fastener 30a coming into contact with the patient and causing pain to the patient can be further reduced.

[0054] Furthermore, a double-sided tape 32 extending in the front-rear direction is provided between the cutout 28 and the second hook-and-loop fastener 30b in the left-right direction. The double-sided tape 32 has a front-rear dimension substantially equal to that of the cutout 28. As with the double-sided tape 24 described above, an adhesive bandage may be attached to the double-sided tape 32 instead of a release sheet, and an adhesive bandage having adhesive properties on both sides may be used instead of the double-sided tape 32.

[0055] Furthermore, a tube insertion portion 34 through which a tube is inserted is provided in the middle portion in the front-rear direction of the bag-shaped main body 12. The tube inserted into the tube insertion portion 34 may be, for example, an artificial respirator tube or a tracheal tube that is intubated into or removed from the trachea of ​​a patient, or a suction tube that aspirates air from within the treatment bag-shaped body 10.

[0056] In this embodiment, three tube insertion portions 34 are provided in the middle of the upper sheet-like portion 14 in the front-rear direction, one trachea insertion portion 34a is provided at a position offset to the right of the center of the upper sheet-like portion 14 in the left-right direction, and two suction insertion portions 34b, 34c are provided at a position offset slightly to the left of the center of the upper sheet-like portion 14 in the left-right direction. The two suction insertion portions 34b, 34c are spaced apart from each other in the front-rear direction, and in this embodiment, the rear suction insertion portion 34b is for a suction tube with a larger diameter than the front suction insertion portion 34c. The front suction insertion portion 34c is provided behind the first and second hook-and-loop fasteners 30a, 30b provided on the lower sheet-like portion 16, and the trachea insertion portion 34a is provided behind the rear suction insertion portion 34b. Since the three tube insertion portions 34 (trachea insertion portion 34a, and suction insertion portions 34b, 34c) all have approximately the same structure, only the trachea insertion portion 34a will be described with reference to FIG. 3, and a detailed description of the suction insertion portions 34b, 34c will be omitted.

[0057] The trachea insertion portion 34a of this embodiment is configured to include a circular hole 36 penetrating the upper sheet-like portion 14 in the thickness direction, and a separate sheet 38 superimposed on the outer surface side of the upper sheet-like portion 14. The separate sheet 38 is a substantially rectangular sheet, and is made of the same soft synthetic resin as the upper sheet-like portion 14. The separate sheet 38 is formed with a fragile portion 40 formed by a cross perforation, and the upper sheet-like portion 14 and the separate sheet 38 are superimposed so that the fragile portion 40 is located within the circular hole 36. This allows the artificial respirator tube or tracheal tube to be inserted through the trachea insertion portion 34a by breaking through the fragile portion 40.

[0058] In the tube insertion part 34 (trachea insertion part 34a) consisting of the upper sheet-like part 14 and the separate sheet 38, a reinforcing member 42 is attached so as to cover the outer periphery of the fragile part 40. That is, the reinforcing member 42 is in the form of a plate having an insertion hole 44 penetrating in the thickness direction, and is formed of a synthetic resin such as polypropylene having a strength greater than that of the upper sheet-like part 14 and the separate sheet 38. The reinforcing member 42 is provided between the upper sheet-like part 14 and the separate sheet 38, and is disposed so that the fragile part 40 is located within the insertion hole 44. That is, the tube insertion part 34 of this embodiment has a three-layer structure consisting of the upper sheet-like part 14, the reinforcing member 42, and the separate sheet 38 from the inside.

[0059] In this embodiment, the reinforcing member 42 is rectangular and has approximately the same size as the separate sheet 38, and the reinforcing member 42 and the separate sheet 38 are fixed to each other by thermal welding. In particular, in this embodiment, the reinforcing member 42 and the separate sheet 38 are fixed to each other by thermal welding at eight circumferential points (points shown in gray in FIG. 3) on the outer circumferential side of the insertion hole 44. It is preferable that such welding points include four points that are the ends of the cross perforations. The reinforcing member 42 and the separate sheet 38 fixed to each other are fixed to the outer surface of the upper sheet-like portion 14 so as to cover the circular hole 36. Note that the method of fixing the reinforcing member 42 and the separate sheet 38 to the upper sheet-like portion 14 is not limited, and may be, for example, welding or adhesion, but in this embodiment, the reinforcing member 42 and the separate sheet 38 are fixed to the upper sheet-like portion 14 by attaching a tape 46 from the upper side of the separate sheet 38. In FIG. 3, the tape 46 is shown by a two-dot chain line for ease of viewing the drawing.

[0060] The diameter of the circular hole 36 and the through hole 44, and the size of the fragile part 40 (length of the perforation) are not limited, but in this embodiment, the diameter of the through hole 44 is slightly larger than the size of the fragile part 40 (length of the perforation), and the diameter of the circular hole 36 is slightly larger than the diameter of the through hole 44. In the trachea insertion part 34a, the diameter of the circular hole 36 and the through hole 44, and the size of the fragile part 40 are not limited by the outer diameter of the artificial respirator tube or tracheal tube to be inserted, and may be larger or smaller than the outer diameter of the artificial respirator tube or tracheal tube. The same is true for the suction insertion parts 34b and 34c, and the diameter of the circular hole 36 and the through hole 44, and the size of the fragile part 40 are not limited by the outer diameter of the suction tube to be inserted into the suction insertion parts 34b and 34c. Furthermore, such tube insertion portion 34 (trachea insertion portion 34a, suction insertion portions 34b, 34c) may be sealed, for example by attaching tape or the like from the outside so as to cover the fragile portion 40, before the tube (ventilator tube 56 or suction tube 64) described below is inserted, thereby preventing the tube or the like from unintentionally piercing the tube insertion portion (weak portion) and establishing communication between the inside and outside of the bag-shaped main body 12.

[0061] Furthermore, a glove-like portion 48 is provided at the rear portion of the bag-like main body 12, extending from the surface of the bag-like main body 12 toward the internal space 20. That is, in this embodiment, the glove-like portion 48 is provided on the inner surface of the upper sheet-like portion 14, and an arm-insertion opening 50, which serves as an arm insertion opening into the glove-like portion 48, is formed on the outer surface of the upper sheet-like portion 14, which is the surface of the bag-like main body 12, penetrating the upper sheet-like portion 14 in the thickness direction. In this embodiment, a pair of arm-insertion openings 50, 50 are formed behind the trachea insertion portion 34a, separated from each other in the left-right direction. In particular, in this embodiment, the left-right center between the pair of arm-insertion openings 50, 50 is biased to the right from the left-right center of the upper sheet-like portion 14.

[0062] A glove-like portion 48 is provided for each of the pair of arm-insertion openings 50. The glove-like portion 48 has a certain length in the front-rear direction, and is formed with a length dimension that not only allows five fingers to be inserted at the tip portion but also covers at least the forearm to some extent. In this embodiment, as shown in Fig. 4, the glove-like portion 48 is formed separately from the upper sheet-like portion 14, and the opening end of the glove-like portion 48 through which the arm is inserted (the upper end opening in Fig. 4) is attached to the arm-insertion opening 50 provided in the upper sheet-like portion 14.

[0063] Specifically, a ring body 52 harder than the upper sheet-like portion 14 is provided around the arm insertion opening 50 in the upper sheet-like portion 14. In this embodiment, the ring body 52 is fixed to the outer surface side of the upper sheet-like portion 14. The method for fixing the ring body 52 to the outer surface side of the upper sheet-like portion 14 is not limited, but for example, the ring body 52 can be fixed to the outer surface side of the upper sheet-like portion 14 by making a cut in the portion of the upper sheet-like portion 14 located on the inner periphery side of the ring body 52, folding it back to the outer surface side of the upper sheet-like portion 14, and heat welding the upper sheet-like portions 14 together with the ring body 52 sandwiched therebetween.

[0064] An elastic annular member 54 such as a rubber band is provided at the opening end (the upper end opening in FIG. 4) of the glove-like portion 48. As a result, the opening end of the glove-like portion 48 is an elastic opening end whose opening size is elastically narrowed. For example, the inner diameter dimension φA (see FIG. 4) of the elastic annular member 54 in its natural state is smaller than the outer diameter dimension φB (see FIG. 1) of the ring body 52. ​​As a result, the elastic annular member 54 at the opening end of the glove-like portion 48 is elastically deformed to expand in diameter and hooked on the ring body 52 to release the deformation, whereby the elastic annular member 54 elastically restores its original shape, and the glove-like portion 48 is attached to the ring body 52 at the opening end. In particular, by providing the ring body 52 on the outer surface side of the upper sheet-like portion 14, it is possible to easily attach the elastic annular member 54 (glove-like portion 48) to the ring body 52, and when a medical professional inserts his / her arm into the glove-like portion 48, the elastic annular member 54 (glove-like portion 48) is less likely to fall off into the internal space 20.

[0065] Furthermore, in this embodiment, both left and right side portions at the rear end of the treatment bag 10 are folded upward, and the folded tip portions are welded to the upper sheet-like portion 14 to form a substantially cylindrical storage space 55. For example, a rubber band 78 shown in Fig. 12(a) and (b) described later can be stored in this storage space 55. In Fig. 1, the portion folded upward and the welded portion of the upper sheet-like portion 14 are shown in gray, and in Fig. 2(a), the portion of the upper sheet-like portion 14 that is folded upward to form the storage space 55 is shown by a two-dot chain line.

[0066] A method of using the treatment bag 10 of this embodiment will be described below with reference to Figs. 5 to 9. Fig. 5 shows a patient P as a human body to which the treatment bag 10 is attached. The patient P is either infected with an infectious disease or is suspected of being infected, and is connected to an artificial respirator tube 56 and a tube 58 for an IV drip or the like. The patient P lies in a supine position on a bed B, for example, with the artificial respirator tube 56 extending from the patient P in the overhead direction and the tube 58 extending to the side.

[0067] The head H of the patient P is accommodated in the internal space 20 of the treatment bag 10, and the treatment bag 10 is attached to the patient P. That is, the head H of the patient P is lifted, and the lower sheet-like portion 16 is inserted under the head H. At this time, as shown in FIG. 6, the opening portion 18 of the treatment bag 10 has a cut 28, so that the opening portion 18 can be greatly expanded at the cut 28, and the head H of the patient P can be easily accommodated in the internal space 20. In addition, the head H of the patient P is positioned on the first double-sided tape 24a of the lower sheet-like portion 16, and the back side of the patient P's neck is overlapped with the first double-sided tape 24a. Here, for example, before inserting the lower sheet-like portion 16 under the head H of the patient P, the release sheet of the first double-sided tape 24a may be peeled off so that the first double-sided tape 24a is attached to the back side of the patient P's neck when the lower sheet-like portion 16 is inserted.

[0068] That is, the back side of the neck, which is the center of the body axis of the head H of the patient P, is overlapped with the first double-sided tape 24a of the lower sheet-like portion 16, and the center in the left-right direction of this first double-sided tape 24a is biased to one side (right side) from the center in the width direction (left-right direction) of the internal space 20. Therefore, in this embodiment, it is instructed that the position of the center of the body axis of the head H of the patient P accommodated in the bag-shaped main body 12 is set to be biased to one side (right side) from the center in the width direction of the internal space 20.

[0069] As described above, in this embodiment, in the treatment bag 10, the center of the body axis of the head H of the patient P is located on one side (right side) of the width direction center of the bag. In other words, in the treatment bag 10, the service space 60 (see FIG. 7) located on the side of the head H of the patient P is provided on the other side (left side) of the width direction center of the bag. By providing such a service space 60, interference between the practitioner and the treatment bag 10 is suppressed, and treatment such as intubation and extubation of the trachea can be easily performed. In FIG. 1, the service space forming area 62 that becomes the service space 60 during use is shown by a virtual two-dot chain line, but this does not limit the area that becomes the service space 60.

[0070] Next, as shown in Fig. 7, the opening 18 is sealed. At that time, the opening 18 of the upper sheet-like portion 14 is folded in a mountain fold in front of the patient P in a supine position. Specifically, the portion of the opening 18 of the upper sheet-like portion 14 located in front of the patient P is folded in a mountain fold, and the first hook-and-loop fastener 22a and the second hook-and-loop fastener 22b are fixed to each other. Since this fixing is performed by hook-and-loop fasteners, it is releasable and can be fixed repeatedly.

[0071] The first and second hook-and-loop fasteners 22a and 22b are fixed to the opening 18 of the upper sheet-like portion 14, so that the left portion of the upper sheet-like portion 14 is pulled to the right. As a result, the left portion of the lower sheet-like portion 16 continuing from the left portion of the upper sheet-like portion 14 is also pulled, and the portion of the lower sheet-like portion 16 located to the left of the cut 28 moves to the upper side of the bag-shaped main body 12, so that the first and second hook-and-loop fasteners 30a and 30b located to the left and right of the cut 28 face each other in the vertical direction, and the cut 28 is positioned to the left of the bag-shaped main body 12.

[0072] Here, in a state where the head H of the patient P is accommodated in the bag-shaped main body 12, the practitioner's arm is inserted into the glove-shaped portion 48, and the artificial respirator tube 56 is inserted into the tube insertion portion 34 (trachea insertion portion 34a) as described later, so that the arm insertion opening 50 and the trachea insertion portion 34a, which are the openings of the glove-shaped portion 48, are lifted upward as shown in Figs. 7 and 8. As a result, in the internal space 20 of the bag-shaped main body 12, a pocket-shaped portion 63 that is bent downward and hangs down is formed on the bottom side (rear side) of the bag from the arm insertion opening 50. That is, in this embodiment, an upper intended hanging portion 63a constituting the pocket-shaped portion 63 is set on the bottom side of the arm insertion opening 50 in the upper sheet-shaped portion 14, and a lower intended hanging portion 63b constituting the pocket-shaped portion 63 is set on the bottom side of the head H accommodation area in the lower sheet-shaped portion 16. In FIG. 1, a pocket-shaped portion forming region 63c which becomes the pocket-shaped portion 63 during use is shown by a virtual two-dot chain line, but this does not limit the region which becomes the pocket-shaped portion 63.

[0073] Then, tools necessary for treatment, such as a mask and a syringe, are accommodated in the service space 60 and the pocket-like portion 63 in the bag-shaped main body 12 through the slit 28. In this embodiment, the slit 28 is provided in the portion of the bag-shaped main body 12 where the service space 60 is formed, and tools for treatment can be easily inserted and removed from the service space 60 and the pocket-like portion 63 through the slit 28. Even if tools for treatment are accommodated in the service space 60, the risk of these tools interfering with the practitioner during treatment can be reduced. Furthermore, by providing the pocket-like portion 63, tools for treatment that are inserted and removed through the slit 28 and the service space 60 can be accommodated in the pocket-like portion 63 before treatment, for example, or can be taken out from the pocket-like portion 63 during treatment. Note that FIG. 8 shows a state in which a mask is accommodated in the pocket-like portion 63.

[0074] Next, the ventilator tube 56 is cut, for example, at the connector, and the portion connected to the trachea of ​​the patient P is inserted into the trachea insertion portion 34a of the upper sheet-shaped portion 14 from the inner side. Specifically, as shown in Fig. 9, the ventilator tube 56 breaks through the fragile portion 40 from the inner side of the upper sheet-shaped portion 14, thereby inserting the ventilator tube 56 into the trachea insertion portion 34a. Thereafter, the ventilator tube 56 is reconnected outside the treatment bag 10, and the supply of oxygen to the patient P is resumed.

[0075] Then, after the artificial respirator tube 56 is inserted into the trachea insertion portion 34a, the release sheet of the second double-sided tape 24b is peeled off, and the overlapped second double-sided tape 24b is fixed to each other by folding in a mountain fold. As a result, the opening portion 18 of the bag-shaped main body 12 is sealed with a higher degree of fixation or adhesion than that between the first hook-and-loop fastener 22a and the second hook-and-loop fastener 22b. In this way, when sealing the opening portion 18 of the bag-shaped main body 12 with the first and second hook-and-loop fasteners 22a, 22b and the second double-sided tape 24b, the opening portion 18 of the upper sheet-like portion 14 is folded in a mountain fold, so that the opening amount of the opening portion 18 is narrowed. Then, a narrowing sealing portion for sealing the opening amount narrowed is composed of the hook-and-loop fasteners 22 (the first and second hook-and-loop fasteners 22a, 22b) and the double-sided tape 24, particularly the second double-sided tape 24b.

[0076] That is, in this embodiment, a two-stage sealing operation is possible, which is sealing by the first constriction sealing portion consisting of the first and second hook-and-loop fasteners 22a, 22b, and sealing by the second constriction sealing portion consisting of the double-sided tape 24, particularly the second double-sided tape 24b. In particular, in this embodiment, the first constriction sealing portion (first and second hook-and-loop fasteners 22a, 22b) is a temporary fastening portion that can be repeatedly fastened, and the second constriction sealing portion (second double-sided tape 24b) is a permanent fastening portion that has a higher degree of fastening or adhesion than the first constriction sealing portion, and the second constriction sealing portion is provided closer to the opening side, i.e., lower than the first constriction sealing portion, so that the opening portion 18 can be permanently fastened by the second constriction sealing portion while the opening portion 18 is temporarily fastened by the first constriction sealing portion.

[0077] In addition, when the front portion of the patient P's head H of the upper sheet-like portion 14 is folded in a mountain fold at the middle portion in the opening width direction and held in a shape protruding toward the front side, the fastening portion that holds the opening side ends of the upper sheet-like portion 14 in an overlapping state on both sides in the opening width direction (left and right direction) is composed of first and second hook-and-loop fasteners 22a, 22b and a second double-sided tape 24b.

[0078] The left-right center of the area where the first and second hook-and-loop fasteners 22a, 22b and the second double-sided tape 24b that maintain the mountain-folded state are arranged is biased to one side (right) from the center in the width direction (left-right direction) of the internal space 20. Also, the trachea insertion portion 34a through which the artificial respirator tube 56 extending from the patient P in the overhead direction is inserted is biased to one side (right) from the left-right center of the upper sheet-like portion 14, and the area where the pair of arm insertion openings 50, 50 are arranged is also biased to one side (right) from the left-right center of the upper sheet-like portion 14. In this embodiment, due to these factors, it is instructed that the position of the body axis center of the head H of the patient P accommodated in the bag-like main body 12 is set to be biased to one side (right) from the center in the width direction of the internal space 20.

[0079] Furthermore, the tube 58 extending laterally from the patient P is sandwiched between the upper and lower sides of the slit 28 and extended to the outside through the slit 28. After the tube 58 is aligned to an appropriate position in the slit 28, the first hook-and-loop fastener 30a and the second hook-and-loop fastener 30b are fastened to each other to close the slit 28. This fastening is releasable because it is achieved by a hook-and-loop fastener, and can be repeatedly fastened.

[0080] Thereafter, the release sheet of the third double-sided tape 24c on the lower sheet-like portion 16 is peeled off, and the third double-sided tape 24c is overlapped and adhered to the second double-sided tape 24b on the upper sheet-like portion 14. The third double-sided tape 24c may be adhered to, for example, a portion of the upper sheet-like portion 14 that is further rearward than the second double-sided tape 24b.

[0081] As described above, by folding the right side of the opening 18 of the upper sheet-like portion 14 in a mountain fold, the left side of the opening 18 of the upper sheet-like portion 14 is pulled to the right, and the left side of the lower sheet-like portion 16 is positioned on the upper side of the bag-like main body 12. As a result, when the head H of the patient P is accommodated in the internal space 20 of the bag-like main body 12, the third double-sided tape 24c that will be positioned on the left side of the bag-like main body 12 can be attached to the back surface of the shoulder of the patient P, depending on the physique of the patient P and how much the treatment bag-like body 10 covers the patient P. Also, the second double-sided tape 24b can also be attached to the front or back surface of the shoulder of the patient P, for example, except for the parts that are folded in a mountain fold and fixed to each other. That is, in this embodiment, the positioning adhesive surface that is provided in the opening 18 of the bag-like main body 12 and can be fixed to the surface of the human body (patient P) is configured to include at least one of the first to third double-sided tapes 24a to 24c.

[0082] Furthermore, if necessary, the release sheet of the double-sided tape 32 located to the right of the cutout 28 is peeled off and adhered to the upper sheet-like portion 14 located above the double-sided tape 32. This allows the cutout 28 to be closed with a higher degree of adhesion or closeness than that achieved by the first hook-and-loop fastener 30a and the second hook-and-loop fastener 30b. That is, in this embodiment, the first and second hook-and-loop fasteners 30a, 30b and the double-sided tape 32 constitute a closing seal that closes the cutout 28 by adhering the circumferential side edge portions sandwiching the cutout 28 to each other.

[0083] Particularly, in this embodiment, the first closure seal consisting of a temporary fastening portion capable of repeated fastening is constituted by the first and second hook-and-loop fasteners 30a, 30b, and the second closure seal consisting of a permanent fastening portion having a higher fastening or adhesion than the first closure seal is constituted by the double-sided tape 32. When the slit 28 is located at the leftmost position in the bag-shaped main body 12, the second closure seal (double-sided tape 32) is provided on the slit 28 side (left side) of the first closure seal (first and second hook-and-loop fasteners 30a, 30b), so that the slit 28 can be permanently fastened by the second closure seal with the slit 28 temporarily fastened by the first closure seal.

[0084] Thereafter, as shown in FIG. 10, for example, a suction tube 64 is inserted into one of the suction insertion parts 34b, 34c provided on the bag-shaped body 12. This suction tube 64 is connected to a negative pressure source, and the air in the internal space 20 of the treatment bag-shaped body 10 can be sucked through the suction tube 64. By inserting the suction tube 64, the air in the internal space 20 of the treatment bag-shaped body 10 can be sucked at an appropriate timing. The timing of sucking the air in the internal space 20 through the suction tube 64 is not limited, but it is preferable to perform it, for example, when intubating or extubating the artificial respirator tube or tracheal tube. That is, after extubating the artificial respirator tube or tracheal tube, it is considered that bacteria, viruses, etc. carried by the patient P are attached to the artificial respirator tube or tracheal tube. In addition, when intubating or extubating the artificial respirator tube or tracheal tube, vomiting or coughing due to a reflex reaction may occur, and it is considered that bacteria, viruses, etc. are attached to the vomit or droplets. In particular, since the patient P may be conscious during extubation, it is conceivable that the patient may cough. Therefore, by sucking the air in the internal space 20 of the treatment bag body 10 at these times, bacteria and viruses that have spread in the internal space 20 of the treatment bag body 10 can be captured, and the risk of secondary infection of medical personnel can be reduced.

[0085] In particular, in this embodiment, the suction insertion portions 34b, 34c through which the suction tube 64 is inserted are provided at a position offset to the left of the center in the left-right direction of the bag-shaped main body 12, i.e., the suction tube 64 is inserted at the service space 60 or at a position relatively close to the service space 60. Therefore, even when the suction tube 64 is inserted into the bag-shaped main body 12, the influence on the treatment by the practitioner is kept small.

[0086] In the treatment bag 10 of this embodiment having the above-mentioned structure, the opening 18 is sealed in two stages by the first constriction sealing part (first and second hook-and-loop fasteners 22a, 22b) and the second constriction sealing part (second double-sided tape 24b) with the opening amount narrowed, so that the opening 18 is sealed more reliably and the bacteria and viruses carried by the patient P are prevented from spreading to the outside. Moreover, the treatment bag 10 prevents the bacteria and viruses from spreading to the outside, and does not become large as in the conventional structure, making it easier to transport and store, and achieving improved handleability and reduced manufacturing costs.

[0087] In particular, the first constriction sealing part is composed of the first and second hook-and-loop fasteners 22a, 22b and serves as a temporary fastening part that can be repeatedly fastened, so that, for example, if there is a problem with the sealing of the opening 18, the fastening of the first and second hook-and-loop fasteners 22a, 22b can be released and the opening 18 can be sealed again. Also, the second constriction sealing part (second double-sided tape 24b) serves as a permanent fastening part that has a higher degree of fastening or adhesion than the first constriction sealing part, so that after the opening 18 has been temporarily fastened by the first constriction sealing part, the opening 18 can be permanently fastened by the second constriction sealing part.

[0088] In this embodiment, the incision 28 is provided at the side of the treatment bag 10 during use, and the closure seal (first and second hook-and-loop fasteners 30a, 30b and double-sided tape 32) is provided to close the incision 28 by fixing both circumferential side edges sandwiching the incision 28 to each other. This allows the tools required for treatment to be inserted and removed from the treatment bag 10 through the incision 28, and the tube 58 connected to the patient P can be extended laterally to the outside of the treatment bag 10. As a result, the position of the tube 58 in the incision 28 can be appropriately set, and the position of the tube 58 delivered to the outside from the treatment bag 10 can be set with more freedom. After the tools are inserted and removed or the tube 58 is extended laterally, the incision 28 is closed by the closure seal to prevent the spread of bacteria and viruses to the outside.

[0089] Furthermore, since the above-mentioned closing seal includes the first and second hook-and-loop fasteners 30a, 30b as a first closing seal consisting of a temporary fastening portion that can be repeatedly fixed, and the double-sided tape 32 as a second closing seal consisting of a permanent fastening portion that has a higher degree of fixation or adhesion than the first closing seal, the first closing seal maintains the closed state of the notch 28, and if there is no problem with such closure, an even higher degree of closure of the notch 28 can be achieved by the second closing seal.

[0090] The cut 28 is provided in the lower sheet-like portion 16 before use. That is, the opening portion 18 of the upper sheet-like portion 14 has a smaller left-right width dimension due to the portion located in front of the patient P being folded in a mountain fold shape, but by providing the cut 28 in the lower sheet-like portion 16, the left-right width dimension of the opening portion 18 in the upper sheet-like portion 14 can be sufficiently secured, and a mountain fold-shaped portion can be stably provided in front of the patient P. In particular, the cut 28 in this embodiment is provided avoiding the left end portion and the left-right center of the bag-like main body 12, so that when the head H of the patient P is accommodated in the internal space 20 of the bag-like main body 12, the cut 28 is prevented from being located under the head H. In addition, when a mountain fold-shaped portion is provided in the upper sheet-like portion 14, the cut 28 can be stably positioned on the side of the bag-like main body 12.

[0091] In this embodiment, the first and second hook-and-loop fasteners 22a, 22b and the second double-sided tape 24b are provided in the opening 18 of the upper sheet-like portion 14 at a portion located in front of the patient P, and are overlapped and fixed when folded in a mountain fold, so that they are held in a shape protruding on the surface side. This allows stable intubation of the artificial respirator tube 56 or a tracheal tube (not shown) into the trachea and extubation from the trachea in front of the patient P. In particular, since the first and second hook-and-loop fasteners 22a, 22b have a certain degree of strength, mountain folds and maintenance of the folded state can be stably achieved. In addition, by forming a tent-shaped inner space of the bag, the patient's sense of oppression can be minimized, and the bag can be expanded to make the inner space 20 easily visible from the outside. Furthermore, by adjusting the amount of adhesion between the first hook-and-loop fastener 22a and the second hook-and-loop fastener 22b, and between the second double-sided tape 24b, it is possible to appropriately set the opening size and position of the opening portion 18 according to the body type of the patient P, the surgical position, etc.

[0092] Furthermore, in this embodiment, the bag-shaped main body 12 is provided with a glove-shaped portion 48 extending into the internal space 20, and a ring body 52 that is harder than the bag-shaped main body 12 is provided at an arm insertion opening (arm insertion opening 50) of the glove-shaped portion 48. This prevents the arm insertion opening 50 from collapsing during use and maintains it as a circular hole, making it easy to insert the arm. Also, in this embodiment, the glove-shaped portion 48 is formed as a separate body from the bag-shaped main body 12 and attached to the ring body 52, so that the bag-shaped main body 12 and the glove-shaped portion 48 can be easily formed, and the design freedom of the bag-shaped main body 12 and the glove-shaped portion 48 can be improved.

[0093] In particular, in this embodiment, the elastic annular member 54 is provided at the opening end of the glove-like portion 48, and the opening end of the glove-like portion 48 is made to be an elastic opening end. This allows the glove-like portion 48 to be easily attached by hooking it onto the ring body 52.

[0094] Furthermore, in this embodiment, intended hanging portions 63a, 63b that hang down when in use are provided on the bottom sides of the upper sheet-like portion 14 and the lower sheet-like portion 16, respectively, and these intended hanging portions 63a, 63b form a pocket-like portion 63 that opens up inside the bag-like main body 12 by utilizing the bottom portion of the bag-like main body 12. Therefore, tools and the like necessary for treatment can be stored in the pocket-like portion 63 in advance, and the necessary tools and the like can be taken out of the pocket-like portion 63 as appropriate during treatment and used, or removed or unnecessary tools and the like can be stored so as not to interfere with the treatment work, without having to be taken out of the bag.

[0095] In this embodiment, the center of the body axis of the head H of the patient P is located on one side (right side) of the center in the left-right direction in the internal space 20 of the treatment bag-like body 10, and the service space 60 is provided on the other side (left side) of the center in the left-right direction. By providing such a service space 60, treatment such as intubation and extubation of the trachea of ​​the patient P can be performed while suppressing interference with the treatment bag-like body 10.

[0096] Furthermore, the bag-shaped main body 12 of this embodiment is provided with a tube insertion portion 34 (tracheal insertion portion 34a, suction insertion portions 34b, 34c) through which the ventilator tube 56 or suction tube 64 is inserted, and a reinforcing member 42 is provided on the outer periphery of the circular hole 36 in the tube insertion portion 34. This allows the shape of the circular hole 36 to be stably maintained even when the ventilator tube 56 or suction tube 64 is inserted, making it easy to insert the ventilator tube 56 or suction tube 64 into the tube insertion portion 34.

[0097] The tube insertion portion 34 is provided with a fragile portion 40, and a tube such as the artificial respirator tube 56 or the suction tube 64 can be inserted into the tube insertion portion 34 by breaking through the fragile portion 40. In particular, in this embodiment, the fragile portion 40 is perforated, and the fragile portion 40 can be brought into contact with the outer circumferential surface of the tube after the tube is inserted, and the release of bacteria and viruses through the tube insertion portion 34 can also be suppressed.

[0098] Alternatively, the inner diameter of the insertion hole 44 in the tube insertion portion 34 can be made smaller than the outer diameter of the tube (the ventilator tube 56 or the suction tube 64) to be inserted, and the tube can be pushed in while being in contact with the inner peripheral edge of the insertion hole 44, thereby ensuring the airtightness of the tube insertion portion 34. In particular, even in such a case, the separate sheet 38 and the reinforcing member 42 are fixed by thermal welding at multiple points on the outer periphery of the insertion hole 44, so that the insertion hole 44 can be effectively prevented from being pushed wide. In addition, when a cross-shaped perforation is adopted as the fragile portion 40, by welding four points on the perforation ends, it is possible to prevent a tear caused by the insertion from extending beyond the welded points when the tube is inserted. It is preferable that the inner diameter of the circular hole 36 in the tube insertion portion 34 is set to be larger than the outer diameter of the tube to be inserted. This prevents the upper sheet-like portion 14 from tearing due to the tension or weight of the tube when the tube is inserted through the circular hole 36, causing the circular hole 36 to widen and creating a large hole in the upper sheet-like portion 14.

[0099] In this embodiment, double-sided tapes 24 (first to third double-sided tapes 24a to 24c) are provided at the opening 18 of the bag-shaped main body 12. Of the first to third double-sided tapes 24a to 24c, the second double-sided tape 24b is used to adhere at least a part of the portion folded in a mountain-like shape in front of the patient P, while the remaining parts of the first and third double-sided tapes 24a, 24c and the second double-sided tape 24b can be attached to the portions facing each other in the vertical direction at the opening 18 of the bag-shaped main body 12 or to the surface of the patient P. This can prevent the patient P from being displaced from the bag-shaped main body 12, and can keep the gap between the patient P and the bag-shaped main body 12 small, thereby preventing the spread of bacteria and viruses to the outside.

[0100] Although the embodiments of the present invention have been described above, the present invention should not be interpreted as being limited to the specific descriptions in the embodiments, and can be implemented in various forms with various changes, modifications, improvements, etc. based on the knowledge of those skilled in the art.

[0101] In the above embodiment, it is assumed that a treatment device is installed on the right side of the patient (left side in FIG. 1), and the head H of the patient P is positioned on the right side of the treatment bag 10 in FIG. 1, and a service space 60 is provided on the left side of FIG. 1 to ensure space for handling piping connected to the device, but the service space 60 may be provided on the opposite side depending on the installation location of the device, the patient's condition, the type of treatment, etc. That is, the head H of the patient P may be positioned on the left side of the treatment bag in FIG. 1, and a service space may be provided on the right side of FIG. 1. In this case, it is preferable that the part to be folded in a mountain shape is provided on the left side of FIG. 1 in the opening part of the bag-shaped main body, and the cut extending from the opening part to the bag bottom part is provided on the right side of FIG. 1 in the lower sheet-shaped part. However, the cut extending from the opening part to the bag bottom part is not essential in the present invention, and multiple cuts may be provided at different positions in the circumferential direction of the opening part.

[0102] In the above embodiment, the tube insertion portion 34 has a three-layer structure consisting of the upper sheet-like portion 14, the reinforcing member 42, and the separate sheet 38, and the perforated weak portion 40 is provided in the separate sheet 38, but the present invention is not limited to this embodiment. For example, FIG. 11 shows a tube insertion portion 70 in another embodiment of the present invention. In the embodiment shown in FIG. 11, the tube insertion portion 70 of the upper sheet-like portion 14 is formed with a cross-shaped perforated weak portion 40, and a ring-shaped reinforcing member 72 is attached to the outer periphery of the weak portion 40. That is, the reinforcing member 72 has an insertion hole 74 in the center, and the perforated weak portion 40 is formed on the inner periphery of the insertion hole 74. In this embodiment, the reinforcing member 72 is fixed to the inner surface side of the upper sheet-like portion 14, and in other words, the tube insertion portion 70 consisting of the upper sheet-like portion 14 is overlapped so as to cover the insertion hole 74.

[0103] The method of fixing the reinforcing member 72 to the inner surface of the upper sheet-like portion 14 is not limited, and may be, for example, fixing by adhesive or heat welding. In this embodiment, the reinforcing member 72 is fixed to the inner surface of the upper sheet-like portion 14 by a substantially rectangular double-sided tape 76. In addition, the position where the double-sided tape 76 is provided in the reinforcing member 72 is not limited, but when a cross-shaped perforated fragile portion 40 is used as in this embodiment, for example, the double-sided tape 76 is preferably provided at the four ends of the cross-shaped perforation as shown by the two-dot chain line in FIG. 11. This can prevent a tear caused by the insertion from extending beyond the fixing position when the tube is inserted into the tube insertion portion 70. However, the shape of the double-sided tape 76 is not limited to a rectangular shape, and may be a ring shape corresponding to the reinforcing member 72. Moreover, the length of the perforations is preferably set within a range of, for example, approximately half to approximately the same length as the inner diameter of the reinforcing member 72 (the diameter of the insertion hole 74).

[0104] 12(a) and (b) show a state where a tube (suction tube 64) is inserted into the tube insertion part 70. That is, as shown in FIG. 12(a), a rubber band 78 may be inserted around the suction tube 64 in advance, and as shown in FIG. 12(b), after the suction tube 64 is inserted into the tube insertion part 70, the rubber band 78 may be moved to the tip side in the insertion direction of the suction tube 64 to make it pass over the reinforcing member 72. As a result, the elasticity of the rubber band 78 that has passed over the reinforcing member 72 is applied to the upper sheet-like part 14, and the upper sheet-like part 14 is annularly fastened by the rubber band 78 against the outer circumferential surface of the suction tube 64 inserted inward from the tube insertion part 70, thereby reducing the gap between the suction tube 64 and the upper sheet-like part 14. As a result, bacteria and viruses in the internal space 20 of the bag-like main body 12 can be prevented from diffusing into the external space through the tube insertion part 70. Such rubber bands 78 can be stored in advance, for example, in storage space 55 formed in treatment bag 10. The gap between the tube insertion portion and the tube to be inserted may be reduced by, for example, applying tape that sealed the tube insertion portion before use across the outer circumferential surface of the tube and the tube insertion portion after the tube is inserted. This can further prevent bacteria and viruses in internal space 20 of bag body 12 from spreading to the outside. The configuration of reducing the gap between the tube insertion portion and the tube to be inserted by using rubber bands or tape can also be adopted in the first embodiment.

[0105] Therefore, as in the embodiment shown in Figures 11 and 12, the fragile portion may be provided on the upper sheet-like portion, and the tube insertion portion may have a two-layer structure consisting of the upper sheet-like portion and the reinforcing member. That is, the reinforcing member may be provided on the outer periphery of the fragile portion provided on the upper sheet-like portion, in other words, the fragile portion provided on the upper sheet-like portion may be located within the insertion hole of the reinforcing member. The reinforcing member may be provided on the outer surface side of the upper sheet-like portion, or on the inner surface side as in the embodiment shown in Figures 11 and 12. Also, the tube insertion portion may be configured by fixing a rubber valve having a slit to the upper sheet-like portion, and the artificial respirator tube or tracheal tube may be inserted by pushing open the slit in the rubber valve.

[0106] Furthermore, in the above embodiment, the hook-and-loop fasteners 22 (first and second hook-and-loop fasteners 22a, 22b) and the double-sided tapes 24 (first to third double-sided tapes 24a to 24c) are provided partially around the circumference of the opening 18 of the bag-shaped main body 12, but these hook-and-loop fasteners and double-sided tapes may be formed around the entire circumference of the opening. Also, in the above embodiment, the first to third double-sided tapes 24a to 24c are provided at substantially equal positions in the front-to-rear direction of the bag-shaped main body 12, but for example, the first double-sided tape may be provided further back than the second and third double-sided tapes. This makes it easier to align the first and third double-sided tapes when, for example, attaching the first double-sided tape to the back of the patient's neck and attaching the third double-sided tape to the back of the patient's shoulder.

[0107] Furthermore, in the above embodiment, the glove-like portion 48 was formed as a separate body from the bag-like main body 12 and attached to the ring body 52, but the glove-like portion may be fixed to the bag-like main body by double-sided tape, welding, adhesion, etc., or may be formed integrally, and the ring body provided at the arm opening is not essential in the present invention.

[0108] Also, the bag-shaped main body 12 may be partially transparent as long as the area required for treatment is visible from the outside. For example, the lower sheet-like portion 16 may be opaque, or may be colored to make treatment tools and the like easier to see. Also, it is possible to set a specific color only to specific locations, such as the area where the head should be placed or the edge of the opening, which makes it easier to recognize specific locations and facilitates work compared to when the entire body is transparent.

[0109] Furthermore, the edge of the opening 18 of the bag-shaped main body 12 may be partially protruding in the circumferential direction to be longer or shorter toward the bottom side. For example, by shortening the side facing the patient's back, the length that is inserted into the patient's back can be shortened to reduce the amount that the patient's upper body is lifted, and by lengthening the side facing the patient's chest, it is possible to improve the sealing by attaching it to the chest like a drape.

[0110] Furthermore, depending on the method of treatment or procedure and the patient's condition, it is also possible to insert and install a rigid frame member inside the bag-shaped main body, thereby reliably and stably securing an appropriate amount of space at the required location inside the bag-shaped main body, and also providing stable support for piping, etc. [Explanation of symbols]
