Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a sanitary bag of a medical material such as a disinfectant used for storing various medical materials such as a gauze, a bandage, a cotton ball, a swab, and a drug-impregnated cloth.
[0002]
[Prior art]
Conventionally, as a medical material sanitary bag, for example, a medical material sanitary bag 100 as shown in FIG. The sanitary bag 100 is used for storing medical materials such as gauze, bandage, and sanitary cotton, and is welded to three sides of a pair of rectangular films 101 made of synthetic resin by welding. The band 102 is formed, and an opening 103 for taking a medical material in and out is provided above.
[0003]
Between the opposing surfaces of the films 101 immediately below the openings 103, for example, a band-shaped fastener 104 made of synthetic resin is interposed as an openable and closable sealing portion. The belt-shaped fastener 104 includes a male fastener 105 welded to one side of the film 101 and a female fastener 106 welded to the other side. The male fastener 105 is provided with a convex ridge 105a extending in the longitudinal direction and having a circular cross section as viewed in cross section, while the female fastener 106 is provided with a dovetail-shaped concave in cross section as provided corresponding to the convex ridge 105a. The groove 106a is formed in a recess, and the opening 103 is sealed by press-fitting the ridge 105a into the groove 106a, thereby preventing moisture and microorganisms from entering the sanitary bag 100.
[0004]
[Problems to be solved by the invention]
By the way, in the conventional sanitary bag 100 as described above, the band-shaped fastener 104 as the opening sealing portion is formed of a slightly hard synthetic resin material to be slightly thicker. In a state where the opening 103 is opened (opened) by disengagement of the two and the opening 103 is opened in the opposite direction, the male and female fasteners 105 and 106 are elastically deformed, so that the restoring force or the restoring force of the bag itself is used. As shown in FIG. 6 (b), the opening 103 is narrowed and finally closed, and the internal medical material cannot be easily removed using tweezers or the like. There was a problem that it was inferior.
[0005]
In order to solve such a problem, as shown in FIG. 7, an annular body 107 made of a rigid material may be fitted into the opening 103 with the opening 103 of the sanitary bag 100 opened. In this case, the opening state of the opening 103 can be maintained by the shape retaining force of the annular body 107 made of a rigid material.
[0006]
However, when taking out the medical material from the inside of the sanitary bag 100, the annular body 107 is fitted into the opening 103 one by one, or the annular body 107 is removed from the opening 103 after use, and the opening 103 is sealed. In addition to the need to perform an operation, extra work is not only added, but also the fitting of the annular body 107 into the sanitary bag 100 from the outside, which is not always in a sanitary environment, has a great hygiene problem. .
[0007]
The present invention has been made in view of the above-described various problems, and has as its object to provide a sanitary bag of a medical material such as a disinfectant capable of maintaining a stable open state of the opening portion in a hygienic manner.
[0008]
[Means for Solving the Problems]
The present invention relates to a medical material sanitary bag in which an opening sealing portion for opening and closing the opening portion is provided on the sanitary bag main body,
An opening holding member is provided in the sanitary bag body or the opening sealing portion so that the opening state of the sanitary bag body can be held,
The opening holding member is provided so as to be deformable in accordance with opening and closing of the sanitary bag main body and to maintain its shape in an open state.
[0009]
According to the present invention, in a state where the opening sealing portion of the bag body is opened, the opening holding member that maintains the shape of the opened state functions to hold the opened state of the bag body. The opening seal portion and the elastic force of the bag body close the opening in the closing direction and close the opening, which eliminates the inconvenience that the operation of removing the medical material from the bag body becomes difficult. The medical material can be easily taken out of the bag main body without the holding jig in contact with the inner wall of the bag, so that the operability and sanitation of medical work are improved.
[0010]
In the present invention, it is preferable that the opening holding member is made of a material that can be plastically deformed in response to opening and closing of the sanitary bag main body, and that the opening state of the bag main body can be held by maintaining the shape when the opening is opened. .
According to such a configuration, when the state is changed from the sealed state to the opened state, the opening holding member is plastically deformed and maintains the shape at the time of opening, so the opening holding member is opened against the restoring force of the bag body and the opening sealing portion. The state can be sufficiently maintained.
[0011]
In such a configuration, the plastically deformable material may be a metal wire or a plasticized polyester wire containing a polyethylene terephthalate-based polyester and an inorganic powder.
With these wires, in the open state, the shape can be sufficiently maintained against the restoring force of the bag body and the opening sealing portion, and the open state can be sufficiently maintained. .
[0012]
Here, as the metal wire, a wire made of copper, iron, stainless steel or the like can be used.
In the present invention, the plasticized polyester wire refers to a wire made of polyethylene terephthalate-based polyester and an inorganic powder, which is more easily plastically deformed than the polyester single wire.
The term “polyethylene terephthalate-based polyester” is a concept including polyethylene terephthalate and terephthalic acid or ethylene glycol, which is a raw material of polyethylene terephthalate, in which a part of terephthalic acid or ethylene glycol is substituted with another dicarboxylic acid or glycol component.
[0013]
Here, examples of other dicarboxylic acid components include isophthalic acid, 2,6-naphthalene carboxylic acid, 1,4-cyclohexanedicarboxylic acid, adipic acid, sebacic acid, dimer acid, and sulfonic acid metal salt-substituted isophthalic acid. And other glycol components include diethylene glycol, neopentyl glycol, 1,4-cyclohexanediol, 1,4-cyclohexanedimethanol, and polyalkylene glycol. Further, in addition to these components, a chain branching agent such as pentaerythritol, trimethylolpropane, trimellitic acid, trimesic acid, boric acid and the like can also be used.
[0014]
Examples of the inorganic powder include calcium chloride (anhydrous or hydrated), barium sulfate, shell (or calcium carbonate), glass (or silica), talc, clay, kaolin, woslanite, mica, titanium oxide, carbon black, diatomaceous earth, and metal. , Dawsonite, magnesium hydroxide, aluminum hydroxide and the like. Among these, at least one selected from the group consisting of calcium chloride, calcium carbonate, barium sulfate and glass powder is preferred.
Usually, the particle diameter of the inorganic powder is preferably about 0.2 to 100 μm.
The content of the inorganic powder is preferably from 20 to 150 parts by weight, particularly preferably from 40 to 100 parts by weight, based on 100 parts by weight of the polyethylene terephthalate-based polyester.
[0015]
In addition, the plasticized polyester wire, within a range that does not impair the plasticity of the wire, other components, for example, inorganic powder other than the above, an antioxidant, a sequestering agent, an ion exchange agent, a coloring inhibitor, A lightfast agent, a flame retardant, an inclusion compound, an antistatic agent, a coloring agent, a wax, a silicone oil, a surfactant, a reinforcing agent, a plasticizer, and the like may be blended. When the cross section is circular, the diameter of the plasticized polyester wire is preferably about 0.10 to 0.75 mm. Usually, a plurality of such plasticized polyester wires are used at the same time or used collectively to function as an opening holding member.
[0016]
Such a plasticized polyester wire can be manufactured by a general method, for example, a method of blending each component, melt-spinning, stretching, and winding.
[0017]
Incidentally, the plasticized polyester wire may be covered with a plastic film layer 4.
The plastic forming the plastic film layer 4 is not particularly limited as long as it does not impair the plasticity of the plastic strap 1 of the present invention, and examples thereof include polyesters such as polyethylene terephthalate. .
[0018]
In the present invention, a configuration may be adopted in which the opening holding member is made of an elastic material that is elastically deformable in response to opening and closing of the sanitary bag main body and urges from the sealed state to the open state.
[0019]
Further, the present invention provides a sanitary bag main body provided with an opening sealing portion that allows the opening to be freely opened and closed, wherein an opening holding member such as a wire is provided near the opening sealing portion, and the opening state of the bag main body is changed Provided is a sanitary bag for a medical material, wherein the sanitary bag is configured to be held.
[0020]
According to such an invention, in a state where the opening sealing portion of the bag body is opened, the opening holding member provided near the opening sealing portion functions to hold the opening state of the bag body. As a result, the inconvenience that the opening is closed and closed by the elastic force of the opening sealing portion and the bag body in the direction in which the opening is closed, thereby making it difficult to take out the medical material from the bag body, is solved. It becomes possible to easily take out the medical material from the bag body without the holding jig such as being in contact with the inner wall of the bag, and the operability and sanitation of medical work are improved.
[0021]
In the present invention, the bag body is an aluminum foil, an aluminum-deposited film, an aluminum oxide-deposited film, a silicon-deposited film, a polyvinyl alcohol film, a polyacrylonitrile film, any one of an ethylene vinyl alcohol film and a polyvinylidene chloride film, or any of them. It is preferable to use a laminate film containing any of the above.
[0022]
According to such a configuration, since a vapor-deposited film, a polyvinyl alcohol film, and the like have extremely excellent sealing properties, the evaporation of moisture inside is prevented by sealing the bag body made of the film with the opening sealing portion. Medical material can be prevented from drying out, and conversely, moisture can be suppressed from entering the interior to maintain a dry state, and the intrusion of microorganisms into the bag body can be reliably prevented, The sanitary condition inside the body can be maintained.
[0023]
In the present invention, the opening holding member is preferably made of a plastically deformable material such as a wire, or an elastic material such as a leaf spring formed in an arc shape.
[0024]
When the opening holding member is made of a material such as a wire that can be plastically deformed, use a wire or the like whose plastic deformation force (force for maintaining the plastically deformed shape) is larger than the elastic deformation force of the opening sealing portion. Thereby, the open state of the bag body is maintained by plastic deformation of the wire with the opening sealing portion opened.
[0025]
Further, the opening holding member is formed in an arc shape, and is made of an elastic material such as a leaf spring having an elastic force larger than that of the opening sealing portion. The open state is maintained.
[0026]
As described above, the configuration of the opening holding member is simplified by using, for example, a wire that can be plastically deformed as the opening holding member or a leaf spring that is formed of an elastic material having an arc shape. It is possible to reliably maintain the open state of the opening.

FIG. 3 is a sectional view taken along line AA of FIG. As shown in these figures, the sanitary bag 10 includes a pair of rectangular laminated films 20 each having a predetermined size, and a band-shaped fastener interposed between the pair of laminated films 20 so as to extend in the width direction. (Opening sealing portion) 30, and wire interior tapes 40 are respectively attached to the front side of each laminated film 20 directly below the band-shaped fastener 30.
[0028]
In this embodiment, a so-called aluminum vapor-deposited film in which a thin layer of aluminum vapor-deposited on one synthetic resin film is covered with the other synthetic resin film is used as the laminate film 20 in the present embodiment. The three edges (both side edges and the lower edge) are subjected to a welding process in a state where the pair of laminated films 20 are superimposed on each other, and a welding zone 22 is formed in this portion. A bag body 11 (FIG. 2) having an opening 21 is formed.
[0029]
By employing such a laminate film 20, the bag body 11 has extremely good airtightness in a state where the bag body 11 is sealed by the band-shaped fastener 30, thereby effectively preventing the evaporation of moisture inside, or conversely. The intrusion of moisture into the inside is prevented, and the intrusion of microorganisms into the bag body 11 is reliably prevented.
[0030]
The band-shaped fastener 30 is for sealing the opening 21 of the bag body 11 in a closed state, and is made of a slightly hard synthetic resin material which can be easily elastically deformed.
[0031]
The band-shaped fastener 30 includes a male fastener 31 and a female fastener 32 arranged to face the male fastener 31. The male fastener 31 includes a long flat plate portion 33 and a convex ridge 34 having a circular cross-section extending in the longitudinal direction and protruding from a surface of the flat plate portion 33 facing the female fastener 32.

On the other hand, the female fastener 32 includes a flat plate 33 similar to the above, and a weir 35 protruding from the surface of the flat plate 33 facing the male fastener 31 so as to correspond to the ridge 34. A dovetail groove 36 having a circular cross section extending in the longitudinal direction and having a circular cross-section in a state facing the protruding ridge 34 is formed in the recess 35. Then, the male fastener 31 and the female fastener 32 are integrated in a close contact state by press-fitting the convex ridge 34 into the concave groove 36, and the male fastener 31 and the female fastener 32 are separated by peeling them off. Has become.
[0033]
In such a band-shaped fastener 30, the flat portion 33 of the male fastener 31 is welded to the upper position of one of the laminated films 20 so as to extend in the width direction, and the flat portion 33 of the female fastener 32 faces the male fastener 31. As described above, the three edges of each of the laminated films 20 are subjected to the welding process as described above in a state of being welded to the other laminated film 20 so that the bag-shaped fastener 11 is attached to the bag main body 11. It has been made.
[0034]
The wire interior tape 40 includes a pair of adhesive tapes 41 and a wire (opening holding member) 42 sandwiched between the adhesive surfaces of the pair of adhesive tapes 41 so as to extend in the longitudinal direction. As shown in FIG. 2, the sanitary bag 10 is finished by welding the wire interior tape 40 in parallel with the band-shaped fastener 30 with the bag body 11 sandwiched immediately below the band-shaped fastener 30 in the bag body 11. I have.
[0035]
The wire 42 has a plastic deformation force larger than the elastic deformation force of the male fastener 31 and the female fastener 32, so that the male fastener 31 and the female fastener 32 follow the plastic deformation in a state where the wire 42 is plastically deformed. , So that it is not restored to its original state.
[0036]
The wire interior tape 40 has a length dimension set slightly shorter than the width dimension of the bag body 11, and has an arc-shaped notch 43 provided on the wire 42 at each edge. The presence of the notch 43 prevents the wire 42 from protruding to the outside, thereby ensuring safety. The wire 42 sandwiched between the adhesive tapes 41 forms an opening holding member of the present embodiment.
[0037]
FIG. 4 is a perspective view showing a state where the opening 21 of the sanitary bag 10 is opened. That is, according to the sanitary bag 10 of the present embodiment, each of the upper edges of the pair of laminated films 20 is picked up with a finger and spread in the opposite directions to each other, as shown in FIG. The stop is released, and the opening 21 of the bag body 11 is opened.
[0038]
In a state where the opening 21 is opened, the pair of wire-containing tapes 40 is such that the central portion bulges in an arc shape in a direction away from each other along the opening shape of the opening 21 when the wire 42 is plastically deformed. The medical material such as gauze stored in the bag body 11 can be easily taken out using a jig such as tweezers.
[0039]
Therefore, even if the opening portion 103 of the sanitary bag 100 is once opened as in the conventional sanitary bag 100 (FIG. 6), the opening portion 103 is narrowed and closed by the elastic force of the belt-shaped fastener 104. The inconvenience that it is difficult to take out the medical material so that efficient medical work cannot be performed can be surely eliminated by employing the sanitary bag 10 of the present invention.
