Description

[Technical Field]

[0001] The present invention relates to a protective sheet. More specifically, the present invention relates to a protective sheet for preventing needle removal, which is used to prevent needle removal accidents during needle puncture, for example, in dialysis treatment. [Background technology]

[0002] It has been known that needle removal accidents are a particularly serious type of medical accident. As a preventive measure against needle removal accidents, a technology has been used, such as that disclosed in Patent Document 1, in which the insertion site where the needle was punctured is covered with a transparent adhesive film dressing material, thereby enabling early visual detection of accidents such as needle removal accidents and drug solution leakage.

[0003] Furthermore, for users who are dementia patients or the like and are forced to use restraint belts, Patent Document 2 discloses a technology that allows the user to wear dialysis needle removal protective clothing with a transparent upper arm and forearm that includes at least the insertion site where the needle is inserted, such as the shunt site, so that the insertion site can be seen from the outside but the user cannot directly touch the insertion site with their own hands, thereby preventing needle removal accidents even for the user. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2017-209403 [Patent Document 2] Japanese Patent Application Publication No. 2017-172066 Summary of the Invention [Problem to be solved by the invention]

[0005] However, the technology disclosed in Patent Document 1 makes it difficult to prevent the possibility of epidermal peeling during removal due to the adhesiveness, or to prevent accidents that can occur when the adhesive comes into contact with the circuitry during removal. Furthermore, for example, it is difficult to prevent users with dementia from removing the needle themselves by avoiding the adhesiveness. Furthermore, it is also difficult to prevent accidents in which the user unconsciously removes the adhesive film dressing, regardless of the disease.

[0006] Furthermore, although the technology disclosed in Patent Document 2 can prevent the user from directly touching the puncture site and thereby inhibiting self-removal of the needle, in an emergency in which an accident such as a drug solution leak or spontaneous needle removal occurs, it is difficult to deal with the situation quickly because the user needs to operate a zipper or the like to remove the garment. Furthermore, it is time-consuming to have the user put on and take off the dialysis needle removal preventive garment each time it is used.

[0007] In other words, the challenges were to protect the puncture site without attaching it directly to the user's body, to be able to visually check the condition of the puncture site while protecting it, to be easy to wear, and to be able to quickly remove it in an emergency such as when a drug solution leaks or the needle comes out.

[0008] The present invention has been made to solve the above-mentioned problems in the conventional technology, and aims to provide a protective sheet that protects the puncture site without being directly attached to the user's body, allows easy visual confirmation of the condition of the puncture site while protecting it, can be quickly released in an emergency such as a drug solution leak or needle removal accident, and is easy to attach and remove. [Means for solving the problem]

[0009] In order to achieve the above object, the protective sheet of the present invention has the following configuration: (1) A protective sheet for preventing needle removal accidents during puncture, It does not attach directly to the user's body, but The puncture site and the puncture needle and tube connected to the puncture site are covered with the an adhesive portion for fixing the protective sheet in a wrapped state; The adhesive portion is adjacent to the A non-porous area that has no temper , a through hole adjacent to the non-perforated portion and a perforated portion having a temper. The adhesive portion is provided only on one end of the protective sheet. The non-perforated portion and the perforated portion are non-adhesive and are configured so as not to stick to the user's body during use.

[0010] The above-mentioned configuration (1) of the automatic mixer of the present invention has the following effects. That is, according to the above configuration (1), the adhesive portion allows the protective sheet to be easily fixed by wrapping it around the puncture site without being directly attached to the user's body, the breathable perforated portion prevents stuffiness and rashes when worn, and the non-breathable non-perforated portion prevents damage between the adhesive portion and the perforated portion, thereby increasing the durability of the protective sheet. Furthermore, the non-adhesive nature of the non-perforated and perforated portions prevents epidermal peeling when removed, and the lack of direct adhesion to the body makes it possible to maintain a comfortable wearing state.

[0011] The present invention Protective sheet of In the configuration of (1) above, the following (2) to ( 5 ) is preferable.

[0012] (2) In the configuration of (1) above, the protective sheet has transparency that allows the puncture site to be visually recognized and liquid-proofness. One sheet It is made of film material.

[0013] According to the preferred configuration of (2) above, the transparency of the protective sheet makes the puncture site visible, allowing for prompt visual recognition of any leakage of drug solution or accidents involving needle withdrawal, and enabling appropriate measures to be taken before such incidents occur. Furthermore, the liquid-proof property prevents contamination of the body by liquids from outside the protective sheet, and also makes it possible to use the protective sheet during care such as bathing.

[Figure 2] 1 is an image diagram illustrating a method for attaching a protective sheet 1 according to an embodiment of the present invention. [Figure 3] 1 is an image diagram illustrating a method for removing protective sheet 1 according to an embodiment of the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0020] The present invention will be described in more detail below using preferred embodiments, but the following embodiments are merely examples of realizing the present invention and the present invention is not limited thereto.

[0021] [Protection Sheet Configuration] First, the configuration of a protective sheet 1 according to an embodiment of the present invention will be described with reference to FIG.

[0022] 1 is a conceptual diagram illustrating the configuration of a protective sheet 1 according to this embodiment. First, the configuration of protective sheet 1 will be described.

[0023] As shown in Figure 1, protective sheet 1 is a protective sheet for preventing accidental withdrawal of the needle during puncture. It is made of a single sheet of transparent and liquid-proof film material and is composed of an adhesive part 2 provided at one end (AA' side) of protective sheet 1, a non-perforated part 3 which is not breathable provided adjacent to adhesive part 2, and a perforated part 4 which is breathable and provided at the other end (C-C' side) of protective sheet 1 adjacent to non-perforated part 3.

[0024] The adhesive portion 2 of the protective sheet 1 according to this embodiment may be provided at one end of the non-breathable non-porous portion 3, and may be configured, for example, as an area where an adhesive is applied to one side of the one end of the non-porous portion 3, as shown by the hatched area in Figure 1. When not in use, the adhesive portion 2 may be covered with a release paper (not shown) to protect its adhesiveness, and the release paper is peeled off before use.

[0025] As shown in Figure 1, the non-porous portion 3 of the protective sheet 1 according to this embodiment is provided between the adhesive portion 2 and the perforated portion 4. Because the adhesive portion 2 is provided at one end of the non-porous portion 3, which does not have breathability, it has liquid-proof properties and can prevent the adhesive applied to the adhesive portion 2 from drying out. Furthermore, by providing the adhesive portion 2 between the perforated portion 4, damage caused by re-peeling when adjusting the fixation of the protective sheet 1 attached by the adhesive portion 2 can be reduced, and the durability of the protective sheet 1 can be improved.

[0026] The perforated portion 4 of the protective sheet 1 according to this embodiment has ventilation holes arranged at regular intervals, as shown by the dotted portions in Fig. 1. The ventilation holes in the perforated portion 4 are, for example, holes with a diameter of approximately 0.1 mm to 0.3 mm, and are breathable. Here, the perforated portion 4 is both breathable and liquid-proof. The perforated portion 4's breathability and liquid-proof properties make it possible to prevent stuffiness and rashes at the site to be protected, such as the puncture site, of the user 5, such as a dialysis patient, when wearing the protective sheet 1.

[0027] The protective sheet 1 according to this embodiment has tearability in only one direction, for example, it can be easily torn in the short direction (CC' direction and C'-C direction) as shown in FIG. 1 . When it is tearable in the short direction, it has non-tearability in the longitudinal direction. Note that when it is tearable in the longitudinal direction, it may also have non-tearability in the short direction. By having tearability in the direction perpendicular to the direction in which the protective sheet 1 is wrapped around the area to be protected on the user 5, it becomes possible to tear the protective sheet 1 and remove it from the area to be protected.

[0028] 1 is a protective sheet 1 for the forearm that is made of a film material composed of polypropylene and 25 microns thick, has a longitudinal length of 400 mm, a lateral width of 300 mm, and longitudinal dimensions of the adhesive portion 2, non-perforated portion 3, and perforated portion 4 of 25 mm, 75 mm, and 300 mm, respectively. Here, the protective sheet of the present invention is an example of a protective sheet 1 for the forearm, and is not limited to use on the forearm as long as the protective sheet can be wrapped around the body. For example, the protective sheet may be worn on the relevant part of the body such as the upper arm, leg, abdomen, chest, or head, and the sizes of the adhesive portion 2, non-perforated portion 3, and perforated portion 4 may be changed depending on the part of the body to be used.

[0029] The above is the configuration of the protective sheet 1 according to this embodiment.

[0030] [How to use] Next, a method of use, including a method of attaching and removing the protective sheet 1, will be described with reference to Figures 2 and 3. Note that, although the protective sheet 1 according to this embodiment will be described in an example in which it is used on the forearm, including the puncture site, of a user 5 undergoing hemodialysis in dialysis therapy, the present invention is not limited to use on the body part or in the therapy of this example.

[0031] Figure 2 is an image diagram illustrating a method for attaching protective sheet 1 according to an embodiment of the present invention. Figure 3 is an image diagram illustrating a method for removing protective sheet 1 according to an embodiment of the present invention.

[0032] 2 and 3 are partially omitted schematic illustrations of the forearm and dialysis circuit of user 5 undergoing hemodialysis therapy. The dialysis circuit does not include all devices except for needles 6a and 6b inserted into user 5 and tubes 7a and 7b connecting needles 6a and 6b to the venous blood circuit and arterial blood circuit, respectively, and does not include the shunt in user 5's forearm.

[0033] First, we will explain how to attach protective sheet 1 according to an embodiment of the present invention. As shown in the upper part of Figure 2, the release paper on adhesive portion 2 of protective sheet 1 according to this embodiment is peeled off to expose the adhesive applied to adhesive portion 2 on the forearm of user 5 undergoing hemodialysis, into which puncture needles 6a and 6b have been inserted.

[0034] Next, as shown in the upper part of Figure 2, the perforated portion 4 side (CC') of protective sheet 1 is wrapped in the direction of the chain arrow so as to encase the puncture site on the forearm of user 5, including puncture needles 6a, 6b, and tubes 7a, 7b, and then the adhesive portion 2 side (A-A') of protective sheet 1 is wrapped in the direction of the chain arrow, similar to the CC' side, along with the forearm of user 5, puncture needles 6a, 6b, and tubes 7a, 7b, and adhesive portion 2 is attached and fixed to perforated portion 4 as shown in the lower part of Figure 2. The wrapping direction of protective sheet 1 is not limited.

[0035] As described above, by wrapping and fixing the puncture needles 6a, 6b and tubes 7a, 7b together with the protective sheet 1 around the puncture site on the forearm of the user 5, the puncture site can be protected so that the blood circuit can be seen without being directly attached to the body of the user 5. Furthermore, when wrapping and fixing the protective sheet 1, the tightness can be adjusted by adjusting the position of the adhesive portion 2.

[0036] As shown in FIG. 2, when protecting the forearm of user 5 with protective sheet 1, it is difficult for user 5 to apply protective sheet 1 with one hand, so it may be applied by a medical professional, for example.

[0037] The above is the method for attaching the protective sheet 1 according to the embodiment of the present invention. That is, such a protective sheet 1 prevents direct contact with the puncture site, and therefore, even if the user 5 is a dementia patient, it is possible to prevent the user from removing the needle themselves.

[0038] Next, a method for removing the protective sheet 1 according to an embodiment of the present invention will be described. The upper part of Fig. 3 shows the protective sheet 1 attached using the above-mentioned attachment method. If an accident such as a drug solution leak or the needle coming out naturally occurs when the protective sheet 1 is attached, it is necessary to quickly remove the protective sheet 1 in order to deal with the accident. Here, the protective sheet 1 according to this embodiment is transparent, allowing the puncture site to be visible when the sheet is attached, making it possible to detect such an accident early if it occurs.

[0039] When such an accident is discovered, the protective sheet 1 according to this embodiment has tearability that allows it to tear only in one direction (the protective sheet 1 according to this embodiment is in the short-side direction BB'), and therefore it is possible to remove the attached protective sheet 1 by tearing the protective sheet 1 in the short-side direction from B to B', as shown in the lower part of Figure 3. The direction in which the protective sheet 1 can be torn is not limited, and the attached protective sheet 1 may be removed by tearing it in the short-side direction from B' to B.

[0040] 3, when the forearm of the user 5 is protected by the protective sheet 1, it is difficult for the user 5 to remove the protective sheet 1 with one hand, and therefore the sheet may be removed by, for example, a medical professional. When protecting a region where it is difficult for the user 5 to remove the protective sheet 1 by themselves, such as the forearm, the protective sheet 1 can prevent the user from intentionally or unintentionally removing the protection inappropriately.

[0041] Furthermore, when removing the protective sheet 1 after treatment, the above-described method for removing the attached protective sheet 1 may also be used.

[0042] The above is the method for removing protective sheet 1 according to an embodiment of the present invention. That is, with such protective sheet 1, even if an accident such as a liquid leak occurs when protective sheet 1 is attached, the accident can be discovered early, and the protection of protective sheet 1 can be removed to quickly address the accident. Furthermore, even in the standard specification, protective sheet 1 is inexpensive because it is made of a film material, and is hygienic because it is disposable.

[0043] The above is the method of using the protective sheet 1 according to the embodiment of the present invention.

[0044] Such a protective sheet 1 protects the puncture site without being directly attached to the body of the user 5, and allows the condition of the puncture site to be easily visually confirmed while protecting it, allowing for early detection of accidents.It can also be quickly removed in an emergency due to a drug solution leak or needle removal accident, and is easy to attach and remove.
