Description

Technical Field

The present invention relates to wristbands and methods of manufacturing the same, and in particular to a wristband for identifying a patient in fields such as medical fields by attaching the wristband around the patient's wrist or ankle according to claim 1, and a method of manufacturing such a wristband according to claim 7.

Background Art

A wristband as described in the preamble of claim 1 is already known from JP 2007 176233 A . Moreover, this document discloses a method according to the preamble of claim 7.
JP 2009 223244 A discloses a wristband wherein an ethylene methacrylate copolymer is covered by a layer of polypropylene. JP 2003 164307 A provides a wristband which can be always kept hygienic and comfortable in the touch of wearing.
JP 2005 283992 A discloses a wristband having a printing area permitting to print desired printing information for identifying an individual on the surface of a base material of length which can be wound around a part of a human body.
Conventionally, it is possible to identify a hospitalized patient by attaching a medical-use wristband having full name, birth date, sex, and other necessary information of the patient written or printed around the wrist or the ankle to allow identification of the patient in an examination or a treatment. However, when a hospitalization period is extended, for example 2 to 3 months, and if the wristband itself is not very durable, let alone problems of deformation of the wristband and hygiene issues, problems arise such as a practical trouble of losing indicated information and failure in reading of the information.
However, as the wristband inevitably comes into contact with the patient's skin, it is required that the wristband be soft as much as possible with minimum skin irritation.
Of course, as it is not possible to manage the personal information if the wristband is intentionally removed, it is required that the wristband has a tensile strength so as not to be easily cut, and enough toughness so that the wristband itself must be cut in order to be removed when using a fixation clip to attach to a portion-to-be-attached. It is also required that the wristband may not be flexed or curved and may have the indication information remain for certain so as to allow bar codes and other contents to be readable even in a long-term use. Further, there is a problem that various conflicting properties such as water resistance, oil resistance, grease resistance, and lightweight properties that may possibly have a user forget wearing the wristband as the wristband is light and soft are required in a long-term attachment.

Description of Embodiment

According to the present invention, a wristband having various required properties and a method of manufacturing such a wristband are realized by employing a laminated material including a first water resistant oil resistant material, a flexible material, and a second water resistant oil resistant material and an interlining material having tearing resistance or tensile resistance to constitute a band base material.

Example

Next, the wristband and the method of manufacturing the same according to an embodiment of the present invention will be described with reference to Fig. 1 through Fig. 5. Fig. 1 is a plan view illustrating a wristband 1, and Fig. 2 is an enlarged sectional view taken along line II-II in Fig. 1. The wristband 1 is able to indicate identification information on a surface of a belt-like band base material 2, and may be attached around a portion-to-be-attached (not depicted) such as a hospitalized patient's wrist or ankle in the form of a ring.
The band base material 2 includes an elongated annular cutoff line 3 in order to allow cutting of the wristband 1 of a single strip out from the band base material 2. Further, a plurality the wristbands 1 connected by separation lines 4 such as perforation constitute a belt-like wristband continuous body 1A. Here, a cut out instruction 5 saying "peel off here", an indication saying "print direction →" , and the like are printed in advance at one arc-like end 1B (a left end in Fig. 1) of the wristband 1. A part of the cutoff line 3 at the one arc-like end 1B is a through cutoff line 3A that penetrates through the band base material 2 from its front surface to back surface, and the remaining part of the cutoff line 3 is a semi-through cutoff line 3B (see Fig. 2). Accordingly, it is possible to eliminate a defect of unintentional separation when unused or when mounted on a predetermined printer (such as a thermal transfer printer, not depicted) and printed while transfer, and to facilitate separation in use.
The wristband 1 is provided with a print area 6 in its center along the length, and a first wrapping portion 7 and a second wrapping portion 8 on left and right of the print area 6. The first wrapping portion 7 includes an attachment hole 9 of a required number (2 in the illustrated example), and the second wrapping portion 8 includes a plurality of selection holes 10 of a required number (8 in the illustrated example) in a penetrating manner. The wristband 1 may be attached around the portion-to-be-attached by fixing the attachment hole 9 and the selection holes 10 by a predetermined fixation clip 11. It should be noted that a mark for position detection 12 is printed on a back surface of the wristband 1 in advance in order to allow detection of a position of the wristband 1 when mounted on the printer and printed while transfer.
As illustrated in particular in Fig. 2, the band base material 2 includes a surface base material 13, an interlining material 14, and an embossed material 15.
The surface base material 13 is configured by a laminated material 19 in which a first water resistant oil resistant material 16, a flexible material 17, and a second water resistant oil resistant material 18 are laminated. As the first water resistant oil resistant material 16, polypropylene (PP) subjected to a corona treatment is performed is used, for example. As the flexible material 17, ethylene-vinyl acetate copolymer (EVA) is used, for example. As the second water resistant oil resistant material 18, polypropylene (PP) is used, for example . Here, a front surface of the surface base material 13 is subjected to a surface treatment 20 such that identification information can be printed on the front surface and that the printed information is permanently durable.
The surface treatment 20 is to apply a predetermined coating depending on types and characteristics of an ink or an ink ribbon used in the predetermined printer. Examples of an agent for the surface treatment include surface treatment agents such as a polyester-based, polyurethane-based, or epoxy-based acrylic resin, varnish for printing ink, and a medium agent. Further, in order to improve readability of a bar code and printed letters, it is desirable to add a pigment such as titanium oxide so as to provide a white background and to adjust its white color density (PSC value) to be 75 or greater.
The interlining material 14 is tearing-resistant or tensile-resistant and laminated on a lower side of the surface base material 13. Examples include a soft and durable materials, for example, versatile film base materials such as nylon, polyethylene terephthalate (PET), polypropylene (PP), and polyethylene (PE), and the interlining material 14 is preferably configured by oriented nylon (biaxially-oriented nylon).
The embossed material 15 is an emboss film made from polyethylene, for example, and laminated on a lower side of the interlining material 14. Its back side is a portion that is in direct contact with a surface of the skin, such as the patient's wrist or ankle, and includes an emboss pattern (an embossed portion 21) of various types of concavo-convex pattern provided by extrusion of any method in order to ensure breathability to the skin to dry sweat or moisture. In order to ensure breathability and to reduce skin irritation as much as possible, a sectional shape of the emboss pattern of the embossed portion 21 is circular or oval. It should be noted that while an inorganic or zinc-oxide-based antimicrobial agent is impregnated in order to maintain cleanliness of the skin surface, it is necessary to select an antimicrobial agent that is safe as much as possible as this portion is in direct contact with the skin. Further, while there is a case in which an additive such as an antioxidizing agent or lubricant is added in manufacturing polyethylene, it is desirable to use additive-free polyethylene considering probability that a user of the wristband 1 may have allergies.
Fig. 3 is an enlarged backside view of the embossed material 15, and Fig. 4 is an enlarged illustrative view showing correlation between a spherical portion 22 of the embossed portion 21 of the embossed material 15 and the triangular crista cutis 23 of the skin of the portion-to-be-attached. Specifically, as the embossed portion 21 has the spherical portion 22 whose sectional shape is circular or oval, and the spherical portion 22 is larger than the triangular crista cutis 23 of the skin (see a hatched portion in Fig. 4), this prevents the embossed portion 21, when abutting the skin of the portion-to-be-attached at a predetermined pressure, from crossing the skin and giving irritation directly to a sulcus cutis 23A between the triangular cristae cutis 23, and skin irritation while wearing may be reduced. Further, a too large (too wide) concave portion in the embossed portion 21 gives an influence to printing on a surface portion (a part of the surface treatment 20) due to a head pressure when the printer prints on the wristband 1. Therefore, it is necessary to limit the size and the pitch of the embossed portion 21 such that a range the spherical portion 22 is about 300 µm to 1500 µm, including a case in which the spherical portion 22 is circular or oval. For example, provided that the sectional shape is oval, the size of the spherical portion 22 of the embossed material 15 at its bottom section is desirably such that a length along a short axis is on the order of 300 µm and a length along a long axis is on the order of 500 µm, and a length of a gap between the spherical portions 22 (concave portions) is on the order of 50 µm to 300 µm.
Referring back to Fig. 2, the second water resistant oil resistant material 18 of the laminated material 19 and the interlining material 14 are adhered by a first adhesive layer 24 such as polyethylene, and the interlining material 14 and the embossed material 15 are adhered by a second adhesive layer 25 such as polyethylene.
In the wristband 1 (the band base material 2), thicknesses of the surface treatment 20, the surface base material 13 (the laminated material 19: the first water resistant oil resistant material 16, the flexible material 17, and the second water resistant oil resistant material 18), the first adhesive layer 24, the interlining material 14 , the second adhesive layer 25, and the embossed material 15 are as shown below. However, a tolerance on the order of ±10% is permissible for each value. The surface treatment 20: 1 µm to 10 µm (e.g., 5 µm), the surface base material 13 (the laminated material 19) : 100 µm to 200 µm (e.g., 150 µm), the first water resistant oil resistant material 16 : 10 µm to 20 µm (e.g., 15 µm), the flexible material 17: 80 µm to 160 µm (e.g., 120 µm), the second water resistant oil resistant material 18: 10 µm to 20 µm (e.g., 15 µm), the first adhesive layer 24 : 10 µm to 20 µm (e.g., 15 µm), the interlining material 14: 15 µm to 50 µm (e.g., 25 µm), the second adhesive layer 25: 10 µm to 20 µm (e.g., 15 µm), the embossed material 15 : 100 µm to 160 µm (e.g., 130 µm), and a total thickness of the wristband 1 : 250 µm to 445 µm (e.g., 300 µm to 340 µm). It should be noted that for the laminated material 19 of the surface base material 13, a ratio between lamination thicknesses of the first water resistant oil resistant material 16, the flexible material 17, and the second water resistant oil resistant material 18 is 0.5-2:6-9:0.5-2 (e.g., about 1:8:1).
Further, a specific gravity of the wristband 1 (the band base material 2) as a whole is set to be smaller than 1 by appropriately adjusting the thicknesses and the materials of the surface base material 13 and the interlining material 14. By setting the specific gravity of the wristband 1 as a whole is to be smaller than 1, it is possible to manufacture the wristband 1 that is light enough to float on water, and provide a sense of light-fitting so as to have a user forget wearing the wristband. In the wristband 1, specific gravities of the resins used for the surface base material 13 (the laminated material 19: the first water resistant oil resistant material 16, the flexible material 17, and the second water resistant oil resistant material 18), the first adhesive layer 24, the interlining material 14, the second adhesive layer 25, and the embossed material 15 are as shown below, for example. Polypropylene (PP): 0.90 to 0.91, ethylene-vinyl acetate copolymer (EVA) : 0.92 to 0.94, polyethylene (PE) : 0.92 to 0.97, and nylon: 1.02 to 1.14. It should be noted that while the specific gravity of nylon exceeds 1, it is possible to suppress the specific gravity of the wristband 1 as a whole to be smaller than 1 by appropriately designing the thicknesses of the respective layers as the proportion of nylon to the total thickness of the wristband 1 is small.
When the hospitalized patient is treated within a hyperbaric oxygen treatment room, there is a risk of a short-circuit spark is caused by static electricity due to a friction between the clothes and the wristband 1. In order to prevent such a short-circuit spark, it is desirable to apply or mix an antistatic agent to or in at least one of the surface treatment 20, the laminated material 19 (the first water resistant oil resistant material 16, the flexible material 17, and the second water resistant oil resistant material 18), the interlining material 14, and the embossed material 15. Thus, even while wearing the wristband 1, the antistatic agent prevents electrostatic charging from being generated, and the patient is able to receive a treatment safely in the hyperbaric oxygen treatment room. Examples of the antistatic material to be used include a material obtained by dispersing an appropriate amount of conductive carbon black, black lead, metal oxide, or a surfactant-based electrical conducting material in a vinyl-chloride-based, vinyl-acetate copolymer-based, acrylic-based, urethane-based, or polyamide-based resin.
The wristband 1 (the wristband continuous body 1A) described above may be manufactured by joining the constituting layers together using an extrusion lamination method or a dry lamination method.
Fig. 5 is a schematic side view illustrating a wristband manufacturing apparatus 30 for manufacturing the wristband 1 (the wristband continuous body 1A) . The wristband manufacturing apparatus 30 includes an embossed material molding device 31, a laminated material laminating device 32, and a wristband laminating device 33.
The embossed material molding device 31 provides the embossed material 15 by extruding a film material of the embossed material 15 so as to form the embossed portion 21 on the back surface of the material through a pair of extrusion rollers 34.
The laminated material laminating device 32 provides the laminated material 19 by laminating the first water resistant oil resistant material 16, the flexible material 17, and the second water resistant oil resistant material 18 through lamination rollers 35.
In the wristband laminating device 33, a material for the first adhesive layer 24 is supplied from a first adhesive supply tank 36 to join the embossed material 15 and the interlining material 14, and a material for the second adhesive layer 25 is supplied from a second adhesive supply tank 37 to join the laminated material 19 to an upper side of the interlining material 14. Then, a surface treating device 38 performs the surface treatment 20, a printing device 39 prints the cut out instruction 5 saying "peel off here", an indication saying "print direction →", the mark for position detection 12, and the like in advance, an cutting line forming device 40 forms the cutoff line 3 and the separation line 4, and whereby the belt-like wristband continuous body 1A from which a single strip of the wristband 1 may be cut out is manufactured.
Thus, it is possible to manufacture the wristband 1 that is light, soft, and having required toughness even when attached to the hospitalized patient's wrist or ankle for an extended period of time. The wristband 1 allows high-quality and high-resistant printing by a printer, and gives no discomfort and little sense of wearing even when attached to the hospitalized patient for an extended period of time. The product shape of the wristband 1 may not be deformed to the end, and the information of the patient is maintained perfectly readable without losing any information.
