Claim 1 and FIG. 1 of Japanese Utility Model Laid-Open No. 62-172449. Claim 1 and FIG. 1 of Japanese Patent Laid-Open No. 2007-319535

  The amount of cotton swabs that have been used in the past is not enough to absorb and retain the drug solution (hereinafter also referred to as “amount of liquid that can be embraced”). It was difficult to apply the chemical solution. On the other hand, if a lot of chemicals are stored in a container together with a cotton swab, the chemical will drip inside the container, and when the cotton swab is picked up, the chemicals may drip, or a lot of chemicals may remain after use, resulting in waste. When the seal is sealed, a chemical solution adheres to the seal portion, which causes problems such as hindering sealing.

  Therefore, an object of the present invention is to easily apply a chemical solution to an affected area, and when used, the chemical solution drippings, an excessive chemical solution remains after use, or a chemical solution is applied to the seal part at the time of manufacture. It is an object of the present invention to provide a chemical solution coating kit that does not adhere and prevent the sealing performance.

  For this purpose, the present invention is in communication with a chemical liquid applicator having a chemical liquid application part made of a sponge body and a shaft part, a chemical liquid application part accommodating recess for accommodating the chemical liquid application part, and the chemical liquid application part accommodating recess. A chemical solution application kit comprising: a storage container having a shaft portion receiving recess for storing the shaft portion; and a sheet lid body capable of covering the drug solution applying portion receiving recess and the shaft portion receiving recess. In the recess, together with the chemical solution application part, the same amount of liquid chemical as the liquid application part can be held is accommodated, the shaft part is accommodated in the shaft part accommodation recess, and the chemical solution application part accommodation recess and the shaft part accommodation recess are provided. A chemical solution application kit having a configuration in which a sheet lid is hermetically sealed is proposed.

  In the chemical solution application kit of the present invention, the chemical solution can be immediately applied to the affected part by using the chemical solution applicator by removing the sheet lid from the container and taking out the chemical applicator. In addition, by adjusting the amount of the chemical solution stored in the chemical solution application portion receiving recess to the same amount as the amount of liquid that can be held in the chemical solution application portion, it is possible not only to apply a necessary and sufficient amount of chemical solution to the affected area, Since there is no chemical solution in the concave part where the chemical solution is applied, the chemical solution dripped when applying the chemical solution to the affected area, excess chemical solution remains after use, or the chemical solution adheres to the seal part during manufacturing and seals Will not be disturbed.

BEST MODE FOR CARRYING OUT THE INVENTION

  Hereinafter, preferred embodiments of the present invention will be described. However, the present invention is not limited to the embodiments described below.

  A chemical solution application kit according to an embodiment of the present invention (hereinafter referred to as “this chemical solution application kit”) includes a chemical solution application part 2 composed of a sponge body and a chemical part applicator as shown in FIG. 1, a container 4 having a chemical liquid application part accommodating recess 5 for accommodating the chemical liquid application part 2, a shaft part accommodating recess 4 a for accommodating the shaft part 3, a chemical liquid accommodated in the chemical liquid application part accommodating recess 5, And a sheet lid (not shown) capable of covering the chemical solution application portion receiving recess 5 and the shaft portion receiving recess 4a.

(Chemical solution applicator 2)
The chemical solution application part 2 is preferably formed from a sponge body mainly composed of cellulose having an OH group.
If the chemical solution application part 2 is formed from a sponge body mainly composed of cellulose having an OH group which is a hydrophilic group, the chemical solution, particularly a chemical solution consisting of an aqueous solution (for example, a popidone iodine solution) is easily compatible and can absorb and retain the chemical solution. That is, it is possible to increase the amount of liquid that can be held. Moreover, when the wet state containing the chemical solution is reached, the surface becomes soft and can be applied with a soft feel.

In this case, the sponge body may contain reinforcing fibers in cellulose, which is a base fiber, in order to increase the strength, for example. As the reinforcing fiber, cotton (cotton), flax, ramie, pulp and the like can be used alone or in combination.
For example, those containing 20 to 50 parts by weight of reinforcing fibers, such as cotton fibers, with respect to 100 parts by weight of cellulose are preferred, and those containing 20 to 40 parts by weight are particularly preferred. By containing 20 to 50 parts by weight of the reinforcing fiber, the tensile strength and shape retention can be increased, the shape of the sponge can be maintained even if a lot of chemicals are contained, and the chemical solution can be easily applied to the affected part. .

The porosity of the sponge body of the chemical solution application part 2 is preferably 95 to 99%. If the porosity of the sponge body is 95 to 99%, it is possible to increase the amount of the drug solution that is absorbed and retained, that is, the amount of liquid that can be held, and the absorbed and retained chemical solution is easily released. Can be applied.
The porosity is a value calculated by the following formula (1).
(1) .. Porosity = (true density−apparent density) × 100 / true density The apparent density is the ratio of the weight to the apparent volume (including voids) of the sponge body, and the true density is The ratio of the weight to the substantial volume of the sponge body constituent material obtained by subtracting the void volume from the apparent volume of the sponge body.

  It is preferable that the space | gap of the sponge body of the chemical | medical solution application part 2 is a space | gap connected to the exterior. As will be described later, when the void is formed by the method of eluting the added mirabilite crystal, the void is a void communicating with the outside.

The average diameter of the gaps in the sponge body of the chemical solution application part 2 is preferably 0.1 mm to 3.3 mm, particularly 0.5 mm to 2.0 mm, and particularly preferably 0.7 mm to 0.9 mm. .
If the average diameter of the porosity of the sponge body is 3.3 mm or less, particularly 2.0 mm or less, the amount of the drug solution absorbed and retained, that is, the amount of liquid retention can be increased.
The average diameter of the voids can be obtained by observing with an electron microscope. However, in the production method for forming voids by eluting the added mirabilite crystals, as described later, the particle size and voids of the mirabilite crystals are used. Since the average diameters of these are substantially the same, it can be read as the average diameter of the mirabilite crystals.

It is preferable that the amount of liquid medicine (for example, 10% popidone iodine solution (specific gravity 1.036)) per unit volume of the sponge body constituting the chemical liquid application unit 2 is the same as the volume of the sponge body. Specifically, it is preferably 0.95 to 1.10 g / cm ³ , particularly preferably 0.98 to 1.10 g / cm ³ .
If the amount of liquid that can be held per unit volume is 0.95 to 1.10 g / cm ^3, it is possible to absorb and hold a sufficient amount of chemical solution to be applied to the affected area with a relatively small volume of sponge body. The part 2 and the chemical solution application part accommodating recess 5 can be made smaller, and the need for accommodating extra chemical solution in the chemical solution application part accommodating recess 5 can be eliminated.

The possible amount of liquid hydrate per unit volume is a value calculated by equation (2).
(2) .. Amount of liquid that can be held per unit volume = unit volume weight at the time of liquid absorption−unit volume weight at the time of drying At this time, the unit volume weight at the time of liquid absorption is 10 for the entire specimen (sponge rectangular solid). It is a unit volume weight measured after dipping in a% popidone iodine solution and dipping for 5 minutes and then placing on a metal mesh to remove droplets from the specimen.

It is preferable to use a sponge body having a liquid absorption rate of 0.03 to 0.5 s / g, particularly 0.04 to 0.5 s / g, for the chemical solution application unit 2, particularly a 10% popidone iodine solution.
If the sponge body has a liquid absorption speed of 0.03 to 0.5 s / g, the chemical liquid applicator 1 is inserted into the container 4 and then the chemical liquid is supplied to the chemical liquid application section 2 in the chemical liquid application section receiving recess 5. In this case, since the chemical solution application unit 2 absorbs the chemical solution within an extremely short time, the steps from supplying the chemical solution to the chemical solution application unit 2 to sealing the sheet lid are performed on a series of production lines. The medicinal solution application kit can be manufactured online. Moreover, since it can absorb instantly when a chemical | medical solution is poured into the chemical | medical solution application part 2, a chemical | medical solution does not jump to a seal | sticker part, but can ensure sealing performance more reliably.

The liquid absorption rate of the chemical solution is 10% popidone iodine solution poured into a stainless steel pad, and then the specimen (sponge rectangular solid) is placed in the stainless steel pad and the lower part is immersed in the popidone iodine liquid, and the specimen (sponge body) is made of stainless steel. It can be calculated from the following equation (4) by measuring the time from when it is placed in the pad until the top surface of the specimen is sucked.
(4) .. Liquid absorption speed = measured value (sec) / weight of sample before liquid absorption (g)

The chemical solution application part 2 is a sponge body that is compression-molded only in the thickness direction so that the thickness is 1/4 to 1/10 of that before compression. It is preferable to use a sponge body that expands and restores in the vertical direction.
By using a sponge body that is compression-molded only in the thickness direction so that the thickness is 1/4 or less compared with that before compression, the liquid absorption speed can be increased as described above and the chemical liquid is absorbed. In this case, since the shape is restored and expanded in the thickness direction and the shape after absorption is stabilized, the shape in plan view of the chemical solution application portion receiving recess 5 may be formed slightly larger along the shape in plan view of the chemical solution application portion 2, And the chemical | medical solution application part 2 can be accommodated in the stable state. In addition, it is difficult in the present molding technique to compress only in the thickness direction so that the thickness is less than 1/10 compared to before compression.
From this point of view, the chemical solution application part 2 is a sponge body that is compression-molded only in the thickness direction so as to have a thickness of 1/4 to 1/10, particularly 1/5 to 1/10 of that before compression. Even more preferably.

(Method for producing sponge body)
The method for producing the sponge body as described above is not particularly limited. As a preferred example, chips from wood or the like are dissolved to form fiber, which is treated with an alkali such as sodium hydroxide, and then carbon disulfide or the like is added to make viscose. This viscose is mixed with fine sodium sulfate crystal made of sodium sulfate (sodium salt), molded into a sheet or block, boiled and acid coagulated to elute the fine salt crystal, make it porous, washed with water, dried, Can be obtained by pressing in the thickness direction and compressing.

As a more specific example, wood pulp is immersed in a sodium hydroxide solution, pulverized after pressing to alkali cellulose (crumb), then aged at 17 ° C. for 10 hours, and then carbon disulfide is added to obtain cellulose xanthate, An unaged crumb having a fiber length of 0.1 to 5 mm, sodium hydroxide and water are added to this cellulose xanthate and dissolved to obtain viscose.
The obtained viscose and fine sodium silicate crystals having an average particle size of 0.1 mm to 3.3 mm are mixed while being kept at 16 to 20 ° C. in a mixer. This mixture is pressurized and filled into a mold through an extruder. At that time, the temperature around the extruder is adjusted to 16 to 20 ° C. The mold filled with the mixture is boiled for about 8 hours in a mirabilite bath at about 90 ° C., solidified to elute the fine mirabilite crystals, and the resulting compact is washed with water, dried, Furthermore, it can be obtained by pressurizing and compressing in the thickness direction.
However, in this method, each temperature, time, etc. can be adjusted.

  At this time, the size of the voids in the sponge body can be adjusted by changing the average particle size of the mirabilite crystal, and the voids in the sponge body can be reduced by using the mirabilite crystal having a small average particle size. it can. Therefore, the average particle size of the mirabilite crystals is particularly preferably 0.5 mm to 2.0 mm, and more preferably 0.7 mm to 0.9 mm.

  Sponge body manufactured by compression molding in the thickness direction has a large amount of liquid that can hold the drug solution (capable of lysing), has a high liquid absorption rate, and has a predetermined thickness (for example, around 90% when absorbed) Therefore, the size of the chemical solution application portion receiving recess 5 can be accurately designed according to the supply amount of the chemical solution and the volume of the sponge body.

  Although the shape of the chemical solution application part 2 is not particularly limited, it is preferably a flat plate-like body as shown in FIG. 1 so that a small amount of chemical solution can be efficiently and widely applied.

(Shaft 3)
What is necessary is just to form the axial part 3 of the chemical | medical solution applicator 1 in the shape of a rod, for example. However, the shape can be appropriately changed so as to improve usability.
For example, as shown in FIG. 1, it is also possible to provide the uneven | corrugated surrounding surface part 3b. The shape of the uneven peripheral surface portion 3b can be appropriately changed. For example, as shown in FIG. 1, a cylindrical large-diameter portion is formed over an appropriate length, and the entire peripheral surface of the large-diameter portion is entirely formed. You may make it form the groove | channel thru | or protrusion 3c over a periphery in the several axial direction at appropriate intervals. Moreover, you may make it form in the shape which wound the string around the axial part over the length suitably, and may form the some groove | channel thru | or protrusion 3c.
By forming the grooves or ridges 3c on the surface of the concavo-convex peripheral surface portion 3b in this manner, not only the shaft portion 3 can be easily grasped with a finger, but also the concavo-convex peripheral surface portion accommodating portion 4c that accommodates the concavo-convex peripheral surface portion 3b. By forming grooves or ridges that can engage with the grooves or protrusions 3c on the peripheral surface, not only positioning when inserting the chemical applicator 1 into the container 4 is facilitated, It is possible to prevent the chemical applicator 1 from moving or dropping during transportation and use. Moreover, even when pressure is applied to the chemical solution application unit 2 due to force majeure and the chemical solution oozes out, the chemical solution can be prevented from entering the shaft portion 3 side. In this respect, it is preferable to form the concavo-convex peripheral surface portion 3b from a material capable of absorbing the chemical solution.
The uneven peripheral surface portion 3b may be formed integrally with the shaft portion 3 with the same material, or may be formed with a material different from that of the shaft portion 3 and fixed to the shaft portion 3 later.

The means for fixing the shaft portion 3 to the chemical solution application portion 2 is arbitrary. For example, an engagement portion may be provided so as to engage with each other, pressure bonding may be performed, adhesion may be performed with an adhesive, and fixing may be performed by insert molding. You can do it.
More specifically, as shown in FIG. 1, a wide engaging portion 3 a is provided at the tip of the shaft portion 3, and an adhesive is applied to the wide engaging portion 3 a, while A notch is made, and the wide engaging portion 3a of the shaft portion 3 is inserted into the notch, and the shaft portion 3 and the chemical solution applying portion 2 are bonded and fixed. At this time, by providing the wide engaging portion 3a at the distal end portion of the shaft portion 3, it is of course possible to contribute to preventing the shaft from coming off, but the rigidity of the chemical solution applying portion 2 can be increased, and the chemical solution can be uniformly and widely distributed. It becomes easy to apply.
Alternatively, as shown in FIG. 3 and FIG. 4, after the chemical liquid application part 2 as an insert product is loaded in the mold, the molten resin is injected to sandwich the end of the chemical liquid application part 2. Two wide engaging portions 3a and 3a are formed at the end portions, and the chemical solution applying portion 2 and the shaft portion 3 are fixed so that the end portions of the chemical solution applying portion 2 are sandwiched and fixed between the wide engaging portions 3a and 3a. Can be integrated. If it does in this way, it can integrate, without using an adhesive agent.

(Container 4)
The storage container 4 includes, for example, a chemical solution application portion storage recess 5 that stores the chemical solution application portion 2 and a shaft portion storage recess 4a that stores the shaft portion 3. It can form in the structure provided with the seal collar part 4e so that it may surround.

  The material of the container 4 is not particularly limited, but is preferably formed from a sheet or film made of a resin having shape retention, chemical resistance, barrier properties for suppressing chemical penetration and volatilization, and the like. . For example, polystyrene, polyethylene, polypropylene, polyethylene terephthalate and the like can be preferably used.

It is preferable that the chemical liquid application part accommodating recess 5 is formed to have a larger size in plan view along the planar view shape of the chemical liquid application part 2 so that the chemical liquid application part 2 can be completely accommodated without gaps. . In the example of FIG. 1, a shallow concave portion is formed along the flat plate-shaped chemical solution application portion 2.
At this time, “larger” means that when the chemical solution application part 2 absorbs the chemical solution, it slightly expands in the lateral direction, that is, about 15 to 25% of the whole in the lateral direction. In addition to 15 to 25%, a slight margin (0.5 mm to 5 mm) is preferably added to form a large planar view width.
On the other hand, the depth of the concave portion 5 containing the chemical solution application portion is a length obtained by adding a slight margin (0.5 mm to 5 mm) to the thickness when the chemical solution application portion 2 absorbs the chemical solution and expands and restores in the thickness direction. Preferably, it is formed to a depth of.

  The shaft housing recess 4a may be formed so as to communicate with the chemical solution coating housing housing recess 5 and to completely store the shaft 3. For example, it may be formed in an elongated groove-like plan view shape along the plan view shape of the shaft portion 3, and as shown in FIG. 4b may be provided so that the shaft portion 3 can be easily grasped with a finger.

Moreover, in order to accommodate the uneven | corrugated surrounding surface part 3b provided in the axial part 3, it is preferable to provide the uneven | corrugated surrounding surface part accommodating part 4c.
It is preferable that the concave / convex circumferential surface portion accommodating portion 4c is formed so as to be largely concave / convex along the contour of the concave / convex peripheral surface portion 3b and not to move in the front-rear direction by engaging with the concave / convex peripheral surface portion 3b. For example, the groove 4d in the circumferential direction may be formed side by side so as to engage with the concave / convex circumferential surface portion 3b having a shape in which a string is spirally wound around the shaft portion over an appropriate length. If formed in this way, it is possible not only to prevent the chemical solution applicator 1 from moving in the front-rear direction in the storage container as described above, but also from the shaft portion storage recess 4a to the wide portion 4b side. One chemical outflow can also be prevented.

  The seal collar 4e is a portion for sealing the sheet lid body in an overlapping manner, and is preferably formed with an appropriate width.

(Medical solution)
The type of chemical solution to be stored is not particularly limited. Examples thereof include a disinfecting chemical solution such as popidone iodine solution, alcohol and hydrogen peroxide, a cosmetic solution such as lotion and baby oil, other liquid chemical solutions, and distilled water. Among these, from the viewpoint of easy compatibility with a sponge body mainly composed of cellulose having an OH group, a chemical solution composed of an aqueous solution (for example, a popidone iodine solution) is particularly preferable.

The chemical solution is to be accommodated in the chemical solution application part accommodating recess 5 together with the chemical solution application part 2, but in the present invention, the amount to be accommodated in the chemical solution application part accommodating recess 5 is important. That is, in the chemical solution application part receiving recess 5, the amount of the liquid solution that can be held in the chemical solution application unit 2 together with the chemical solution application unit 2, that is, in a specific numerical value, 90 to 110% by mass of the liquid holding amount. It is important to accommodate.
By storing the same amount of the lysable amount of the medicinal solution application unit 2, that is, 90 to 110% by mass of the lysable amount, it is possible not only to apply a necessary and sufficient amount of medicinal solution to the affected part, Since there is no excess chemical in the recess where the chemical solution is applied, the chemical may drip, excessive excess chemical may remain after use, or the chemical may adhere to the seal part during manufacturing and prevent sealing. It can be lost.
From this point of view, the amount of the chemical solution accommodated in the chemical solution application part accommodating recess 5 is preferably 95 to 105% by mass, particularly 100 to 103% by mass of the amount of the liquid application part 2 that can be hydrated. preferable.

  The amount of the chemical solution stored in the chemical solution application portion receiving recess 5 is preferably changed as appropriate depending on the type and size of the affected part, the size of the drug solution application portion storage recess 5, and the like. It is preferable to adjust the size.

(Seat lid)
The material of the seat lid is not particularly limited, but it needs to be waterproof and chemical resistant. For example, a composite sheet formed by laminating a metal thin film layer on the sheet surface of a resin base sheet can be cited as a preferred example. Specifically, a resin base sheet such as polyethylene, polypropylene, polyethylene terephthalate, aluminum, etc. A composite sheet obtained by depositing or laminating a metal and laminating a metal thin film layer can be preferably used.

(Production method)
The method for producing the drug solution coating kit is not particularly limited. For example, after inserting the chemical solution application part 2 into the chemical solution application part accommodating recess 5 and inserting the chemical solution applicator 1 into the receiving container 4 so as to insert the shaft part 3 into the shaft part accommodating recess 4a, Is preferably poured into the chemical solution application section 2 and then the chemical solution application kit is manufactured by covering and sealing the sheet lid so as to cover the chemical solution application section receiving recess 5 and the shaft portion receiving recess 4a.

Since the chemical solution applicator 1 is accommodated in the container 4 prior to the chemical solution, and then the chemical solution is supplied to the chemical solution application unit 2 in the chemical solution application unit receiving recess 5, the chemical solution application unit 2 absorbs the chemical solution. The chemical can be supplied without spilling.
At this time, with respect to the chemical solution application part 2, the same amount of chemical solution as the lysable amount of the chemical solution application part 2, that is, 90 to 110% by mass of the lysable amount is stored in the chemical solution application part housing recess 5. By supplying to the chemical solution application part 2, it is possible to prevent the chemical liquid from splashing on the seal collar 4 e and the like, and the sheet lid can be covered and sealed in a sealed state.

In such a manufacturing method, as described above, a sponge body that is compression-molded only in the thickness direction so that the thickness is 1/4 to 1/10 of that before compression, in other words, compresses when absorbing a chemical solution. It is preferable to use the chemical solution application part 2 made of a sponge body that expands and restores in the thickness direction by the amount thus formed.
By using a sponge body that is compression-molded only in the thickness direction so that the thickness is 1/4 to 1/10 of that before compression, the liquid absorption speed can be increased and the chemical solution is absorbed. In this case, since the shape is restored and expanded in the thickness direction and the shape after absorption is stable, the plan view shape of the chemical solution application portion receiving recess 5 is slightly larger along the plan view shape of the chemical solution application portion 2. The chemical solution application unit 2 can be accommodated well in a stable state.
From this point of view, the chemical solution application part 2 is a sponge body that is compression-molded only in the thickness direction so that the thickness is 1/4 to 1/10, particularly 1/5 to 1/10, compared to before compression. Is even more preferred.

Similarly, as described above, the chemical solution application unit 2 made of a sponge body having a liquid absorption rate of a chemical solution, particularly 10% popidone iodine solution, of 0.03 to 0.5 s / g, particularly 0.04 to 0.5 s / g. Is preferably used.
In the case of a sponge body having a liquid absorption speed of 0.03 to 0.5 s / g, when the chemical liquid is poured into the chemical liquid application part 2 in the chemical liquid application part accommodating recess 5, the chemical liquid application part 2 is instantaneously entirely. Since it gets wet and absorbs the chemical solution, when the chemical solution is poured into the chemical solution application unit 2, the chemical solution will not scatter, and the time from the supply of the chemical solution to the sealing of the sheet lid can be shortened. Can be carried out on a single production line, and the production of the drug solution application kit can be performed online.

(how to use)
In this chemical solution application kit, after the sheet lid is peeled off from the storage container 4, as shown in FIG. 2, the chemical solution application tool 1 is taken out from the storage container 4, and the chemical solution application part 2 of the chemical solution application tool 1 is applied to the affected part. The chemical solution impregnated in the chemical solution application part 2 can be applied to the affected part, and the excessive chemical solution is not accommodated in the chemical solution application part accommodating recess 5, so that the chemical solution may drip or become extra after use. No excessive chemicals remain.
At that time, the chemical solution application part 2 made of a sponge body as described above is flexible even when impregnated with the chemical solution, so that the chemical solution can be applied to the affected area with a soft coating comfort. Furthermore, since the chemical liquid oozes out without being pressed by simply placing the cellulose sponge 2 on the affected area, the chemical liquid can be uniformly and sufficiently applied to the affected area.

(Other embodiments)
In addition to the medical solution application portion receiving recess 5 and the shaft portion receiving recess 4a for storing the shaft portion 3, a partition is provided, and a medical device receiving recess for receiving medical devices such as tweezers, gauze, bandages, hemostatic tape is provided. A medical instrument can be accommodated in the instrument accommodating recess to form a medical kit.

  Sponge body A was obtained by immersing wood pulp in a sodium hydroxide solution, crushing after pressing to alkali cellulose (crumb), then aging at 17 ° C. for 10 hours, and then adding carbon disulfide to obtain cellulose xanthate. This cellulose xanthate Into the blender, add unripe crumb with a fiber length of 0.1 to 5 mm, sodium hydroxide, and water to dissolve it to obtain viscose. The mixture was kept while maintaining the temperature at 16 to 20 ° C., and water was added to adjust the mixture. This mixture was press-filled into a mold through an extruder. At that time, the temperature around the extruder was adjusted to 16 to 20 ° C. The mold filled with the mixture is boiled for about 8 hours in an about 90 ° C. mirabilite bath and solidified, and the resulting molded body is washed with water, dried, and the thickness becomes 1/5 in the thickness direction. A compression sponge body obtained by pressurizing and compression molding as described above was cut into a predetermined size.

(Measurement of possible amount of liquid)
Pour 10% popidone iodine solution in a quantity sufficient to immerse the entire specimen in a stainless steel pad, immerse the entire specimen in the popidone iodine solution and soak for 5 minutes, and then place it on a metal mesh to remove the droplets from the specimen. Then, the unit volume weight at the time of liquid absorption was measured.
The weight of the sample in a dry state was measured in advance, and the amount of liquid that could be held per unit volume was calculated from the following formula (2).
(2) ··· Amount of liquid held per unit volume = Unit volume weight at the time of liquid absorption-Unit volume weight at the time of drying

(Measurement of liquid discharge rate)
As described above, after measuring the unit volume weight at the time of liquid absorption, the weight of the sample was applied for 200 minutes and allowed to stand for 10 minutes, and then the weight of the sample (: unit volume weight after liquid discharge) was measured. The liquid release rate was calculated.

(Compression rate)
After the specimen was hydrated, the compressibility was measured in a state where water was squeezed lightly enough to prevent dripping.
The compression rate was measured by measuring the thickness (T0: initial load thickness, mm) when a load of 50 g / cm ² was applied to the measurement sample using a compression elasticity tester, and then applying a load of 200 g / cm ^2. The thickness (T1: initial load thickness, mm) was measured, and the compression rate (%) was calculated from the following equation (5).
(5) .. Compression rate = (T0−T1) × 100 / T0
Table 1 shows the average value of n = 3.
In addition, when performing disinfection work, since it is thought that the chemical | medical solution application tool was pressed against the disinfection location with the load of 200 g / cm < ² > or less, the compressibility (%) was measured with the load of 200 g / cm < ² >.

The amount of the sample A that can be hydrated and the liquid absorption speed were extremely large compared to the sample B, and it was found that the sample A can absorb and retain a large amount of the drug solution.
In addition, the liquid discharge rate and the compression rate of the sample A are extremely larger than those of the sample C, and the sample A can release most of the absorbed and retained chemical solution, and the compression rate is higher than that of the sample C (cotton swab). I found that it was soft and gentle to the skin.

(Chemical solution application test)
Each specimen was placed in a stainless steel pad, and 2000 mL of 10% popidone iodine solution was poured into it to absorb the drug solution, and then immediately placed on the skin and moved to compare and examine the application state. As a result, Sample A absorbed the chemical solution instantaneously and absorbed all the poured chemical solution, but Sample B could not absorb all the chemical solution.
In addition, the sample A can be applied evenly by simply moving it on the skin while absorbing the chemical solution, and the chemical solution did not sag. A large amount of the chemical solution oozes out and dripped down, and it was not possible to apply the solution evenly.

(Example)
Using a sponge body of specimen A, as shown in FIGS. 3 and 4, a flat disc-shaped drug solution application part 2 having a thickness of 2 mm and a radius of 15.5 mm was formed.
Another method is to form a round bar having a diameter of 4 mm and a length of 135 mm from polypropylene, and a wide tongue piece (10 mm × 10 mm) 3 a is provided at the top and bottom of the shaft end portion at appropriate intervals. The shaft portion 3 was formed by providing an uneven circumferential surface portion 3b composed of an uneven curved surface portion over an appropriate width (for example, 30 mm) on the portion near the shaft end portion.
Then, after the chemical solution application part 2 as an insert product is loaded in the mold, the resin is injected to form the wide engaging portion 3a of the shaft portion 3 so as to sandwich the end portion of the chemical solution application part 2, and the chemical application The chemical | medical solution applicator 1 was formed by integrating the part 2 and the shaft part 3.

  After the drug solution applicator 1 is inserted into the container 4 so that the drug solution applicator 2 is inserted into the drug solution receiver recess 5 and the shaft 3 is inserted into the shaft receiver recess 4a, From above, a chemical solution in an amount of 80 to 130 (80, 90, 100, 103, 105, 110, 120, 130)% by mass of the liquid application portion 2 of the chemical solution application unit 2 is poured from above. A chemical liquid application kit was manufactured by covering and sealing the sheet lid so as to cover the chemical liquid application part accommodating recess 5 and the shaft part accommodating recess 4a.

  As a result, the amount of the chemical liquid stored in the chemical liquid application part receiving recess 5, that is, the amount of the chemical liquid poured into the chemical liquid application part 2 can apply a necessary and sufficient amount of chemical liquid to the affected part, 90. Since the chemical solution dripped when the chemical solution application unit 2 is taken out from 5, the extra chemical solution remains after use, the chemical solution adheres to the seal part during manufacture, etc. It was found that the amount was preferably -110% by mass, particularly 95-105% by mass, particularly 100-103% by mass.
