Description

[Detailed Description of the Invention] The present invention relates to an infection prevention package that houses a temperature sensitive body of a body temperature measuring device such as a thermistor of a glass thermometer or an electronic thermometer when measuring body temperature.

BACKGROUND ART It is common knowledge not only for medical professionals but also for the general public that measuring the body temperature of any disease, whether it be in humans or animals, is useful for diagnosis.

For example, in hospitals, a thermometer is used to measure body temperature in the hands of many doctors, nurses, and other medical personnel and many patients until it is damaged or lost.

To measure body temperature, the temperature-sensitive part (mercury bath) of the thermometer is placed under the armpit or inserted into the rectum during the day.

These areas to be measured are also breeding areas for pathogenic bacteria, and are also sources of infection or sources of infection.

Among the patients whose body temperature is to be measured, the name of the disease is unknown, such as outpatients, and temperature measurements are often performed without waiting for the results of bacterial tests, which take a relatively long time. If the patient is a carrier, there is a risk that pathogenic bacteria may be transmitted from the patient to the nurse's hands to another patient through the thermometer, causing nosocomial infection.

Therefore, in hospitals, thermometers are sterilized, but because of the function and structure of thermometers to measure body temperature, they cannot be sterilized at temperatures that exceed the temperature measurement limit.

Therefore, methods that allow sterilization and disinfection under conditions below this temperature limit are being implemented.

For example, after using a thermometer, there is a method of sterilizing it by wiping it with a disinfectant wipe such as alcohol cotton or by soaking it in a disinfectant solution.

In either method, one thermometer is used many times in a short period of time because the body temperature of many patients is measured one after another with a limited number of thermometers, and as is the case today, the number of bacteria resistant to various drugs is increasing. In the presence of bacteria, there is no guarantee that the above-mentioned disinfection method and short-time treatment will necessarily kill pathogenic bacteria, and the current situation is that the disinfection effect is not confirmed by methods such as culture tests after each sterilization.

In addition, with simple disinfection, there are many problems with conventional body temperature measurement, such as the patient's mental reluctance to directly touch something used by another person and the unpleasant smell and taste of the disinfectant. It had the following drawbacks.

The purpose of this invention is to prevent contact infection from the patient or animal being measured by inserting and storing the thermosensor in the package when using body temperature measurement instruments such as glass thermometers and electronic thermometers, and to prevent contact infection during handling and handling. It makes it easy and reduces the operation time, improves the adhesion between the package and the temperature sensing part of the body temperature measuring device, increases heat transfer efficiency, shortens the measurement time, and eliminates the discomfort. The reason is that it can be disposed of hygienically after use.

The structure of the present invention is for an infection prevention package in which a hard packaged object such as a thermosensitive body is inserted and housed. It has a bag-like protective cover for storing a packaged object having a depth shorter than its length, and an outer bag enclosing the protective cover, and the protective cover and the outer bag are adhered to each other at the opening. This is an infection prevention package characterized by:

The protective cover is made of a flexible material like paraffin with an elongation rate of 500 to 2000% to improve adhesion to the temperature sensing part.
For example, it is preferable to use a plastic heat-sealing plastic film such as Parafilm (trade name) sold by American Can Company or Cielon (trade name) sold by Fuji Photo Film Co., Ltd.

In addition, the protective cover is formed into a tongue shape, and the outer bag has an open bottom and the bottom edge is bent and tightly attached, or the bottom edge of the outer bag is attached to the bottom of the outer bag. One sheet has an adhesive film, the other side has a paper sheet, and a bonded part with a weak adhesive strength is provided, which is then bonded, so that the bottom part can be easily released by the pushing force of the packaged object. In addition, it is desirable to provide a gripping portion at the bottom end of the one-sided sheet forming the outer bag.

In order to improve the gas permeability of the outer bag during dry sterilization, such as ethylene oxide gas sterilization, at least one sheet of the outer bag should be a sheet with excellent gas permeability, or the bottom of the outer bag should be open and the bottom edge should be folded tightly. It is made by bending and sealing.

The gas permeable sheet is a thin sheet of paper such as bleached kraft paper, a sheet in which a perforated heat-fusible plastic film is laminated on the entire surface or a part of the paper material, or a heat-fusible plastic film on the paper material. It is desirable to use a sheet coated on the entire surface or a part of the surface with regularity such as a polka dot pattern, a mesh pattern, a checkerboard pattern, etc., or a sheet in which the paper material is coated on the whole surface or a part of the surface with an adhesive.

Gas-impermeable sheets include single sheets of heat-adhesive plastic films such as polyethylene, polyvinyl chloride, and ethylene vinyl acetate, biaxially oriented polypropylene films and polyethylene films, uniaxially oriented polypropylene films and polyethylene films, and polyvinyl chloride. A composite sheet coated or laminated with heat-fusible plastic on at least one side, such as film and polyethylene film, bleached kraft paper and polyethylene film, etc., is used.

When the area to be measured is the rectum, applying a lubricant such as glycerin to the outside of the protective cover in advance makes it easier to insert the thermosensor into the area to be measured and reduces the pain caused to the patient. be able to.

Embodiments of the present invention will be described in detail below with reference to the drawings.

Example 1 1 in the figure indicates a protective cover, which is a flexible plastically deformable heat-fusible paraffin film (trade name: CILON) with a thickness of 90μ and an elongation rate of 600% or more (trade name: CILON), length 3Q mm width 25
Two sheets of 2 mm thick sheets are heat-sealed at 170° C. into a tongue shape like 1a, and the outside is cut to form a bag shape.

The top sheet 2 and bottom sheet 3 on the outside are outer bags, and the top sheet 2 is a composite of a polyvinyl chloride film 2a with a thickness of 70 μ and a polyethylene film 2 b with a thickness of 30 μ. or 5mm longer bottom sheet 3 length 35mm width 25mm is date 50g
/m2 bleached kraft paper 3a is laminated with a 15 μm thick perforated polyethylene film 3b from the opening side of the bleached kraft paper to the bottom part.

The top sheet 2 and the bottom sheet 3 are the side 4a and bottom 4b.
Heat seal is applied on both sides to form a bag shape.

The part marked + from the opening side of the outer bag has heat-sealable polyethylene films 2b and 3b on the top sheet 2 and the bottom sheet 3, respectively, and is strongly adhered, whereas the part marked + from the bottom side of the outer bag. Since the top sheet 2 has a heat-sealable polyethylene film 2b and the bottom sheet 3 has only bleached kraft paper 3a, the polyethylene film 2b is melted by heat sealing and impregnated between the fibers of the bleached kraft paper 3a. - Forms a weak adhesive that can be easily peeled off with the force of inserting the thermometer.

The protective cover 1 and the outer bag are heat-sealed at the openings 4C and 4d to form a package.

When this package is dry-sterilized, for example by ethylene oxide gas sterilization, ethylene oxide gas easily infiltrates through the holes in the polyethylene film 3b of the lower sheet 3 and the bleached kraft paper 3a, so that the package is completely sterilized. The inner space surrounded by the outer bag and protective cover and its inner surface are bacteriologically isolated from the outer space and outer surface by adhesion, so that sterilization can be maintained.

In use, as in the usage example shown in FIG. 4, the thermometer 5 is inserted into the package from between the seals 4C and 4d of the opening, and the thermometer 5 is pushed in by pressing the edge of the package with a finger until it is hidden.

At this time, the force of pushing the thermometer 5 causes the protective cover 1 to stretch and further push off the weak adhesive part 4b at the bottom of the outer bag, causing the thermometer 5 to
The protective cover 1 extends in close contact with the thermometer 5 until the user stops pressing .

Since the protective cover 1 exposed from the outer bag is sterilized, it can be used as is for measuring body temperature.

The protective cover 1 and the exterior are adhered at the opening, and the protective cover 1 is in close contact with the thermometer 5, so after measuring body temperature, the protective cover 1 can be removed by pulling out the thermometer 5 from the package.
is turned inside out, with the contaminated surface facing inside, as shown in FIG.

As described above, by using a plastic film with a high elongation rate for the protective cover, it is possible to downsize the thermometer (length: 100 to 120 mm) to about the same size, and to perform sanitary treatment by reversing the contaminated surface. By using a sterilizable gas permeable sheet for the outer bag, sterilization is easy and complete and sterility is maintained until use.

In addition to being hygienically disposed of after use, the package can also be used as a hygienically safe transport container for bacterial testing since the contaminated side is on the inside.

In order to compare the protective cover of this example with the polyethylene film cover, which is larger than the thermometer, thermometers of the same type were stored in a closet, and both were cooled to 15°C and placed in a constant temperature bath set at 40°C. When immersed in the protective cover and measuring the time it took for both to pass 39°C, it was 6 seconds for the oral thermometer and 7 seconds for the Starbi thermometer with the protective cover of this example, but 12 seconds for the oral thermometer with the polyethylene cover. , 15 seconds for the Starbi thermometer, and it was found that the protective cover of this example had a better heat conduction effect than the polyethylene cover.

Example 2 As shown in the cross-sectional view of FIG. 6, the same sheet as the top sheet 2 (thickness 70
A polyvinyl chloride film 2a having a thickness of 30μ and a polyethylene film 2b having a thickness of 30μ glued together) is used, and instead of forming a weak adhesive part at the bottom as in Example 1, the bottom is left open and the bottom end By closely contacting and bending the
It may be a package that allows ethylene oxide gas to enter and exit easily, is protected by a folded portion 6 after sterilization to prevent contamination until use, and is easily opened by the force of extrusion from the thermometer 5.

By using a plastic sheet for the outer bag, it is also possible to apply a lubricant 7 such as glycerin to the outside of the protective cover or the inside of the outer bag to make it easier to push the protective cover human thermometer into the rectum. .

As described above, by using a water-resistant sheet such as a plastic sheet for the outer bag, it is possible to easily use a lubricant and to smoothly measure body temperature, and it is also easy to use as in Example 1. It also has similar effects.

Example 3 The package of Example 3, as shown in FIGS. 7 and 8,
In place of the bottom sheet 3 of the outer bag in Example 1, a basis weight of 50 g/
A composite sheet 8 made by adhering a 15μ thick perforated polyethylene film to the entire surface of bleached kraft paper of m2 is used,
Instead of forming a weak adhesive part on the bottom, a V-shaped notch 9 is cut out in the side adhesive part on the inside of the bottom adhesive part, or a perforation is cut out to expose the protective cover 1 on the inside of the bottom adhesive part. A section 10 is provided.

Since the only difference from Example 1 is the extrusion port of the thermometer, it can be used in the same way as Example 1, and has the same effects.

Example 4 As shown in FIGS. 9 and 10, the package of the present application has a fabric weight of 50, instead of the lower sheet 3 of the outer bag of Example 1 or 2.
g/m2 bleached kraft paper 11 may be used to make the adhesive between the top sheet 2 and the bottom sheet 11 easy to peel off, and the top sheet 2 at the bottom side end may be lengthened to provide the grip portion 12 or 13. .

When in use, as shown in the usage examples in FIGS. 11 and 12, the thermometer 5 is placed in the sterilized package as described in Example 1.
Insert and store the protective cover human thermometer from the extrusion opening of the outer bag, hold the peeling grip part of the top sheet, and pull it off toward you (FIG. 11) to expose the protective cover 1.

At this time, since the lower sheet 11 is supported by the thermometer 5, the upper sheet 2 is easily peeled off.

If the peeled upper sheet 2 and lower sheet 11 are brought together in front (FIG. 12), the protective cover can be used more effectively for a longer period of time than in Examples 1 to 3.

This device uses a protective cover to measure body temperature without touching the thermosensor of the body temperature measuring device, which eliminates the patient's mental reluctance to use other people's equipment, and has a hygienic feature that prevents contact infection. has.

Since the outer bag has a completely sterilizable configuration and structure, the protective cover is completely sterilized, so there is no need to disinfect the temperature sensing part of the body temperature measurement device, and no other sterilization methods are required after use. Give medical personnel the opportunity to safely measure body temperature.

The protective cover and the outer bag are integrated, and the protective cover has a reversing function, so the protective cover and outer bag can be separated before use, and after use, the dirty protective cover can be inserted into the outer bag and thrown away. No complicated operations required.

The protective cover made of a plastic film made of a plastic film with a high elongation rate allows the temperature sensing part of the body temperature measuring device to be in close contact with the protective cover, resulting in good heat conduction efficiency and no discomfort, even after use. When it is pulled out, it is turned over and turned over with the contaminated side facing inside, allowing sanitary and safe disposal.

Each time body temperature is measured, the thermosensor is inserted into a new package and stored.
It can be discarded after use or used as a sample transport container for bacterial testing, and can be operated extremely easily when inserting and storing the thermosensor into or taking it out of the package.

゛It can also be used as a protective cover to prevent finger contact infection during diagnosis, treatment, and testing.

By using a plastic film with a high elongation rate as a protective cover, we can create packaging that is compatible with the shape and size of the thermosensor of body temperature measurement equipment, or a packaging that is large enough to accommodate any thermometer. There is no need to prepare one, and since it is compact, it is convenient for handling such as transportation, storage, management, and disposal.

As described above, the present invention has many advantages.
