Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cover for covering a diaphragm surface of a stethoscope used for medical examination.

[0002]

2. Description of the Related Art There are various hospital-acquired infectious diseases in hospitals, and at present it is difficult to control these infectious diseases. This nosocomial infection is currently of particular concern as MRSA
(Methicillin-resistant Staphylococcus aureus). It is said that this infectious disease is caused by abuse of antibiotics as medical treatment becomes more and more frequent. Therefore, it is difficult to cure because antibiotics do not work, and especially severe cases such as elderly people and children may die.

[0003] In recent years, organ transplantation techniques such as bone marrow transplantation have been developed, but the transplantation of this organ has severely reduced immunity, making it more susceptible to infection. The need for preventive measures is increasing.

[0004]

However, in hospitals, stethoscopes are routinely used for examining a large number of patients, including outpatients. Many people have the problem of the spread of infectious diseases.

[0005] Accordingly, the present invention has been made in view of the above problems, and has as its object to provide a stethoscope cover capable of covering the stethoscope surface and preventing infection.

[0006]

In order to achieve the above object, a first aspect of the present invention is to form a bag covering a diaphragm surface of a stethoscope used for medical examination with a sheet, and to form the bag with a sheet. It is characterized in that fastening means for attaching to the diaphragm is provided at the bag body entrance.

According to the first aspect, the cover for covering the diaphragm surface for the stethoscope can be manufactured at a low cost by being made of a bag formed of a thin sheet, so that the cover can be disposable, whereby the infection can be prevented. Can be prevented.

According to a second aspect of the present invention, the sheet forming the bag is made of a soft resin material.

According to the second aspect, a sheet made of a soft resin material, for example, a soft and thin sheet made of a resin, such as a wrap used for wrapping food at home, does not generate noise and has no acoustic waves. The sound of the stethoscope is not disturbed because the sound is not attenuated.

A third aspect of the present invention is characterized in that the fastening means comprises a rubber ring which is attached to the bag body entrance portion so as to be extendable and contractible. According to the third aspect, the attachment and detachment of the cover is facilitated by expansion and contraction of the rubber ring.

A fourth aspect of the present invention is characterized in that the fastening means is formed by attaching an expanded rubber ring to an outer peripheral edge of a circular and flat sheet.

According to the fourth aspect, the bag is formed by reducing the diameter of the rubber ring, and can be attached to and detached from the stethoscope.

A fifth aspect of the present invention is characterized in that the fastening means is formed by wrapping a rubber ring in an expanded state with an outer peripheral edge of a circular sheet.

According to the fifth aspect, since the rubber ring is not visible, the appearance is good, and the same operation and effect as those of the fourth aspect are obtained.

[0015]

Embodiments of the present invention will be described below with reference to the drawings. 1 to 17 relate to an embodiment of the present invention, FIG. 1 is a diagram showing a state where a cover is attached to a stethoscope, FIGS. 2 and 3 are perspective views showing a stethoscope cover,
4 and 5 are partial cross-sectional views of the stethoscope cover, FIGS. 6 and 7 are perspective views of the stethoscope, and FIGS. 8 to 17 are diagrams illustrating a manufacturing process of the stethoscope cover.

As shown in FIGS. 6 and 7, the stethoscope 1 has a tube 3 connected to a chest piece 2 formed substantially in the shape of a drum, and a diaphragm 4 is stretched over the chest piece 2. The diaphragm 4 is applied to the skin, and the sound transmitted from the skin is heard through the tube 3.

Therefore, the diaphragm 4 side comes into contact with the skin of many people and causes nosocomial infection through the skin. Therefore, in the present invention, the diaphragm 4 side is covered with a stethoscope cover.

As shown in FIGS. 2 and 3, the stethoscope cover 5 of the present invention forms a thin sheet made of a soft resin material, that is, a wrapped sheet used at home in the bag body 6 as shown in FIGS. The part is provided with fastening means 9 for the stethoscope.

As shown in FIG. 4, the stethoscope cover 5 in FIG. 2 has a rubber ring 8 attached to the outer surface of the entrance of the bag body 6 so as to be stretchable.

As shown in FIG. 5, the stethoscope cover 10 shown in FIG. 3 has an opening portion of the bag body 6 formed in a hollow ring 7 and an elastic rubber ring 8 inserted through the hollow portion.

When the stethoscope cover 5 or 6 having this configuration is used, since the chest piece 2 of the stethoscope 1 is formed in a substantially drum shape, the fastening means 9 provided at the entrance of the bag 6 is expanded. As shown in FIG. 1, the fastening means 9 is reduced in diameter by being put on the diaphragm 4 side,
That is, the bag 6 is fixed to the neck 17 and the surface of the bag body 6 on the diaphragm 4 side is in a tensioned state.

When forming the stethoscope cover 5, FIG.
As shown in FIG. 13 to FIG. 13, first, in FIG. As shown in FIG. 9, it is applied intermittently on the circumference.

Next, as shown in FIG. 10, the rubber ring 8 is mounted on the molding die 18 in a state where the diameter of the rubber ring 8 is increased to a diameter that can be fitted to the stethoscope. Next, as shown in FIG. 18 is lowered to the sheet surface, and at the same time, the sleeve 19 is lowered to press the rubber ring 8 against the surface of the sheet 12. Thereby, the rubber ring 8 is fixed to the surface of the sheet 12 by the adhesive 17.

Next, as shown in FIG. 12, the mold 18 and the sleeve 19 are raised, and the bag 6 is removed from the mold 18, whereby the rubber ring 8 is reduced in diameter as shown in FIG. The diameter d is smaller than the diameter of the neck 17 and the bag 6
Is completed.

When forming the stethoscope cover 10, as shown in FIGS. 14 to 17, first, a molding die 13 having a groove 13 into which the rubber ring 8 is dropped is disposed on the upper surface of the sheet 12, and the lower surface of the sheet 12 is disposed on the lower surface. The rubber ring 8 is placed in a state where it is expanded to a diameter that can be fitted to a stethoscope.

Next, as shown in FIG. 15, the rubber ring 8 is pushed up from the back side of the sheet 12 and dropped into the groove 13 together with the sheet 12. As a result, an extra peripheral edge of the sheet 12 protrudes from the groove 13.

Next, as shown in FIG. 16, the peripheral edge of the sheet 12 protruding from the groove 13 is bent downward and its end is fixed to the bag body 6 by an adhesive or heating.

Next, by extracting the bag body 6 from the molding die 14, the rubber ring 8 is reduced in diameter as shown in FIG. 17 to have a diameter d smaller than the diameter of the neck portion 17 of the stethoscope. Complete. Note that it is desirable to use a sterilized sheet material for forming the bag body 6.

[0029]

According to the present invention, the stethoscope cover made of a bag can be easily attached and detached by expanding and contracting the fastening means provided at the entrance portion. The cover can be manufactured at a low cost and can be disposable.

The thin sheet made of a soft resin material constituting the stethoscope cover does not generate noise and does not attenuate sound waves, so that there is no bearing on the sound of the stethoscope.

As described above, if the stethoscope cover is attached to the stethoscope and the medical treatment is performed, it is possible to protect a patient with reduced immunity from infectious diseases.
