JPS63277056A - Carrier of antiseptic solution - Google Patents

Abstract

PURPOSE:To enhance effective sterilizing activity holding capacity and to prevent the generation of dust at the time of processing, by using polyolefinic foam as a carrier to be impregnated with a halogen-containing antiseptic solution. CONSTITUTION:As a halogen-containing antiseptic solution, a povidone-iodide solution, an iodine tincture solution, a benzalkonium chloride solution or the like can be designated. These antiseptic solutions are infiltrated in polyolefinic foam before use. This carrier is markedly reduced in the lowing of effective sterilizing activity holding capacity in spite of a long storage period and easily processed since powdery dust is hardly generated at the time of demolding and easy to handle because of high breaking-resistant strength.

Description

[Detailed description of the invention] [Industrial application fields] The present invention relates to a carrier for impregnating a disinfectant solution.

[Prior Art] In the medical field, carriers impregnated with disinfectant are often used. For example, when a wound occurs, the carrier is grasped with tweezers to disinfect the wound, or when a connector must be connected aseptically, the connector is inserted into a carrier containing disinfectant solution in a container to disinfect the wound. After this, the connectors are connected to each other and are used for various other purposes.

Absorbent cotton or polyurethane foam is widely used as the conventional liquid absorbent material for the carrier.

[Problems to be Solved by the Invention] By the way, it has been recognized that the disinfecting ability, that is, the ability to retain effective bactericidal activity, of carriers impregnated with such a disinfectant usually decreases over time.

Ru. In particular, in the case of polyurethane foam for holding povidone-iodine solution, which is widely used as a disinfectant, the ability to retain effective bactericidal activity has been markedly reduced, leading to concerns about its disinfecting ability. In addition, in producing the carrier, for example, the polyurethane foam is molded into a flat plate shape and then cut into a cylindrical shape using a mold, but during this processing, powdery dust is produced, making post-processing difficult. Furthermore, during disinfection work, the breaking strength was low and it sometimes tore.

The main object of the present invention is to provide a carrier for a disinfectant solution that has a high ability to retain effective bactericidal activity, and another object is to provide a carrier for a disinfectant solution that is less likely to generate dust during processing and has a high breaking strength. be.

[Means for Solving the Problems] In order to achieve this object, the present invention has the following configuration. That is, it is characterized in that a polyolefin foam is used as a carrier for impregnating a halogen-containing disinfectant.

[Example] Generally, polyolefin foams are polyurethane.

It is known to have better heat processability and higher mechanical strength than urethane foam and polystyrene foam. Examples of polyolefin foams include polyethylene foams and polypropylene foams, and polyethylene foams are currently widely used. Types of foam structures can be divided into open-cell structures and closed-cell structures, but open-cell structures are preferable in terms of ease of impregnation with disinfectant and the amount of impregnation. The shape of the foam can be arbitrarily selected depending on the intended use, but it can also be formed into the desired shape by foaming in a mold, or it can be manufactured by cutting the foam.

In addition, halogen-containing disinfectants include povidone-iodine solution,
Examples include iodine tincture solution, benzalkonium chloride solution, benzethonium chloride solution, and hypochlorous acid (IJ) solution. These disinfectants are used by impregnating the above-mentioned polyolefin foam, but it is preferable to package them in a sealed manner to prevent the disinfectants from evaporating. In addition, the packaged product should be sterilized by radiation or high-pressure steam before use.

You can also do that. The present invention will be explained in more detail below using specific examples.

Implementation example The following experiments were conducted on the carrier of the present invention.

First, as a carrier, polyethylene foam was selected from among the polyolefin foams used as carriers of the present invention, and this was compared with a conventional polyurethane foam.

In both cases, open-cell foam was used, which is easily impregnated with disinfectant. The experimental method involved impregnating 1 g of the various carriers with about 10 g of a povidone iodine solution having an effective free iodine concentration of 1%, storing it at room temperature for a predetermined period of time, and then squeezing out the bozedone iodine solution from the carrier. Thereafter, the effective free iodine concentration contained in the squeezed povidone-iodine solution was measured. In addition, free iodine (), using a starch reagent as an indicator, is 0.
Titrated with 01N (normal) sodium thiosulfate.

The storage period for the above items is 10 days, 14 days, 30 days, and 60 days.
Calculated for each period of days. The results are shown in the following table and Figure 1.

Table, effective free iodine concentration (%) Note that three samples were used for each carrier.

It is clear from the table and Figure 1 that polyethylene foam has a higher ability to retain effective bactericidal activity than polyurethane foam.

[Effects of the Invention] According to the carrier for the disinfectant of the present invention, the ability to retain effective bactericidal activity decreases significantly less than that of conventional carriers even if the storage period becomes long. In addition, it is easy to process because it does not produce powdery waste when cutting, and it is easy to handle because it has high breaking strength.
