DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a finger opener,
More specifically, the present invention relates to a finger opening device that can more easily and more accurately prevent inter-finger infections and the like associated with so-called “flexion contracture of the fingers”.

[0002]

2. Description of the Related Art In the past, in the field of medical treatment, care for the elderly, etc., there has been a problem of interfinger infections associated with finger flexion contracture. This finger contracture occurs, for example, during quadriceps flexion contracture in Parkinson's syndrome hypoxic encephalopathy, in addition to spastic paralysis as a sequela of cerebrovascular disease. And
During the finger flexion contracture, pressure is constantly applied between the fingers and the like, and the fingers are in close contact with each other and tend to be in a wet state. This creates an environment where bacteria can easily propagate on the fingers, and may cause infections caused by not only S. epidermidis and fungi, but also MRSA (methicillin-resistant S. aureus).
Particularly in the case of people with weak and weak resistance, the infection can cause severe fever and can be life-threatening.

[0003] For this reason, in the medical field and the like, it is often necessary to use expensive antibiotics and the like to treat this infectious disease, but it is difficult to improve the bad environment due to finger flexion contracture. There are many intractable cases. Therefore, it is considered desirable to surely prevent adhesion between fingers due to finger flexion contracture and to cut off the infection. For this reason, conventionally, the following methods and instruments have been used. For example, a gauze is wound around each finger or a finger selected from each finger (every other finger or the like) to prevent the adjacent fingers from directly contacting each other.
Attempts have also been made to have the patient grasp the ball and prevent sticking between the fingers. Further, as shown in FIG.
Using the device 7 including the grip portion 71 and the finger engaging portion 72,
Attempts have been made to prevent adhesion between fingers. In addition, an instrument (Japanese Utility Model Laid-Open No. 3-24117) including an uneven part formed on the surface side of the finger and having a fastening band for fixing to a patient's hand, and the like, has also been proposed. .

[0004]

SUMMARY OF THE INVENTION The present inventor has described the above
It is considered that if the techniques and instruments exemplified in (1) can be used properly at medical sites, nursing homes and the like, they will be effective in preventing the above-mentioned infectious diseases. However, the present inventor thinks that the appearance of a device that can be used more simply and effectively than the methods and devices exemplified above is desired. That is, a patient, an elderly person, or the like (having a finger flexion contracture) (hereinafter, referred to as a “subject”) squeezes each finger strongly, and the fingers are as if in a “hardened state” (hereinafter, referred to as “subject”). , "Severely ill".) Then, the fingers of such a person are forcibly spread and spread, and the "gauze" described above is wound, the ball described above is gripped, and the finger is engaged with the finger engagement portion 72 of the device 7 described above. Is not always easy. Especially for female nurses and nurses, it is likely to be troublesome work.

[0005] Further, in the above-mentioned appliances, the appliance main body is of an air-injection type, which is improved. However, use of the appliance for a severely ill person still requires a great deal of trouble. Furthermore, in the methods and instruments shown in the above-mentioned, since the finger of the target person is more likely to fall off than the target object such as a ball and a tool, a nurse,
It is necessary for a caregiver or the like (hereinafter, referred to as a “third party”) to frequently hang each finger on a correct place. In addition, compared to the case of using the above-described methods and instruments,
It is desired to ensure a sufficient distance between the fingers of the subject to more reliably prevent infectious diseases. As described above, the appearance of a technique or device for preventing the above-mentioned finger-to-finger infection or the like more simply and more accurately is desired.

[0006] The present invention has been made in view of the above-mentioned viewpoints, and can more easily reduce inter-finger infections associated with finger flexion contracture.
It is another object of the present invention to provide a finger opening device that can prevent the failure more accurately.

[0007]

According to the first aspect of the present invention, there is provided a finger opening device having a top sheet portion and a back sheet portion, a substantially closed bag-shaped opening device body, and a filling device for filling the inside of the opening device body. An injecting / discharging means for injecting a fluid and discharging a filling fluid from the inside thereof, wherein the opener main body has a palm attachment surface to which a part of the exposed side surface of the back sheet portion can be attached to the palm of the subject. And a thumb insertion hole, a forefinger insertion hole, a middle finger insertion hole, a ring finger insertion hole, and a little finger, each of which is configured to penetrate from the exposed side surface of the back sheet portion to the exposed side surface of the top sheet portion. The insertion holes are arranged in this order and along a substantially arc-shaped virtual path line surrounding the periphery of the palm attachment surface.

[0008] The finger opening device of the present invention is mainly composed of a sheet material (sheet portion) having high flexibility, and is capable of freely injecting and discharging a filling fluid. Therefore, even if the target person is a severely ill person, it can be used simply and accurately. That is, if the filling fluid is discharged from the opening tool body,
Work to attach each finger of the subject to each "insertion hole"
This is called “mounting work”. ) Can be easily performed. For example, even if it is difficult to spread each finger of the subject, a third party can pinch the right part of the opener body with a finger to narrow the distance between each "insertion hole" or to adjust the relative distance between each "insertion hole". If the proper position is changed, this mounting work becomes easier.

[0009] Then, if the filling fluid is injected into the inside of the opening device main body after the mounting operation, the opening device body swells to a state in which the opening device body fits perfectly with the fingers of the subject. At this time, each finger of the subject is pressed by the filling fluid around the inner peripheral edge of each "insertion hole", and the interval between the fingers is reliably widened, and each finger is hard to fall out of each "insertion hole". It is said. In addition, a portion of the opening body, which is located around the inner peripheral edge of each “insertion hole” and is filled with an elastic filling fluid or the like, secures a sufficient contact area and disperses the pressure while distributing pressure to each finger of the subject. Gently and almost evenly. Therefore, the feeling of use is excellent.

[0010] The shape of the "opener body" can be variously selected.
For example, a substantially mitt shape, a substantially unpanned shape, and the like can be exemplified. The size of the "opening body" is selected in a range in which the "palm contact surface" as described above can be ensured, that is, a range in which the planar shape is larger than the planar shape of the palm of the subject. Furthermore, the “opening device main body” may be configured using a single sheet-like material, or may be configured using a plurality of sheet-like materials.

Further, the material of the "opening device main body" can be variously selected from materials which do not allow the filling fluid injected into the opening device main body to pass outside the opening device main body. However, if it is intended to improve the usability, it is preferable to use a material having some flexibility. Further, in consideration of continuous use, it is desirable to use a material that does not easily deteriorate due to continuous washing with water or the like. For example, resins such as polyvinyl chloride, natural rubber, and synthetic rubber can be exemplified. Also, this "opening body"
May have a single-layer structure or a laminated structure. For example, even if it is a sheet-like material composed only of a sheet layer having no air permeability, a sheet having no air permeability on both front and back surfaces of a cushion sheet layer (composed of various cushion materials such as polyurethane home and nonwoven fabric). It may be one in which layers are arranged. Further, a sheet-like material having air permeability can be arranged on the exposed side surface of each sheet portion.

Examples of the "filling fluid" include fluids such as silicon and jelly, and semi-fluids, in addition to gases such as air. The structure of the "injection and discharge means" is variously selected. For example, for example, a "valve" provided in a floating bag (for swimming)
And the same as the insect rubber type air injecting / discharging means of the bicycle. The size, arrangement interval, and the like of each of the “insertion holes” are variously selected within a range in which the object of the present invention can be achieved. That is, the size of each “insertion hole” is set to a size that allows each finger of the target person to be inserted, and the arrangement interval is set to an interval that allows each finger of the target person to be inserted into each “insertion hole”.

Further, each "insertion hole" needs to be provided substantially the same as or larger than each finger of the subject. However, each of the “insertion holes” includes a slit-shaped hole that changes into a hole having such a size when each finger of the subject is inserted. In the second invention,
When the filling fluid is injected, the thickness of at least a portion near the center of the portion of the opening main body corresponding to the palm attachment surface is made larger than the thickness of the remaining portion of the opening main body. In the second aspect of the present invention, it is intended to more reliably achieve the object of the first aspect of the invention by pressing the palm-side surface (abdominal surface) of each finger of the subject's finger more reliably.

In the third invention, the palm attachment surface is provided so as to include a part of the outer peripheral edge of the exposed side surface of the back sheet portion, and the palm attachment surface is substantially semi-vertically or substantially longitudinally cut in the opening body. The notched portion is provided in a state of being cut. In the third aspect of the present invention, the opening main body is further easily deformed due to the cutout portion, and the mounting operation is further improved.
It will be easier.

[0015] In the fourth aspect of the present invention, the top sheet portion has front surface side through holes each extending from the inner peripheral edge thereof, each of which has a substantially ring-shaped joint at a location corresponding to each of the insertion holes. And, the back sheet portion is provided with each back side through-hole in which each back side substitute having a substantially ring shape is extended from each inner peripheral edge at a position corresponding to each insertion hole, and each of the front side side joints is provided. Teens,
Each of the front-side joints and each of the back-side joints in a paired relationship are joined in a state of being overlapped to form each joint, and at least the inner peripheral edge side of each joint, It is covered with each protection member made of a predetermined elastic material. According to the present invention, each protective member prevents the finger of the subject from directly contacting the inner peripheral edge of each joint. Therefore, the feeling of use is further improved. Incidentally, examples of the "elastic material" include natural rubber, synthetic rubber, foamed resin and the like.

In the fifth invention, the top sheet portion and the back sheet portion are mainly composed of a resin sheet formed using a resin material to which an antibacterial agent is added. According to the fifth aspect of the invention, since the finger opening device can be used continuously in a more hygienic manner, the objects of the first to fourth aspects of the invention can be more reliably achieved. In addition, as this "antibacterial agent", metallic silver powder,
Silver-carrying ceramic powder in which bactericidal metal ions (eg, silver ions) and the like are supported on powders such as alumina, silica, and aluminosilicates (zeolites), terpene compounds, thyme oil, glove oil, or eucalyptus oil And the like.
