Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a body posture fixing mat, and more particularly to improvement of a body posture fixing mat that maintains the whole or part of a human body in a predetermined state.

Conventionally, when a human body, which is a patient, is placed supine or lying down on a bed and an image is taken by CT (Computed Tomography), MRI (Magnetic Resonance Imaging), or the like, or when an operation is performed, the human body moves for a predetermined period of time. However, it may be difficult to maintain a stationary state depending on the patient's disease state, age, or the like.

Therefore, conventionally, there has been a demand for a posture fixing mat that is laid on a bed and fixes (or retains) the human body without restraining it with a band or the like.

Such a conventional cushion body is composed of a futon-like gas-impermeable quilted bag and a gas-permeable cushion body that is housed inside and filled with foam beads. By degassing by sucking air and contracting the cushion body itself, the entire body is deformed into an arc shape in cross section, and the human body of a patient lying supine or lying on the cushion body is sandwiched from both sides and fixed. (See Patent Document 1, for example).

Japanese Patent No. 6002189

However, the body position fixing mat disclosed in such a prior art document has a one-layer structure in which a large number of beads are filled in a cushion body arranged in parallel. The pressure at the part of the body that comes into contact with the patient's body is partially increased, and since surgery and examinations take a predetermined time, the patient's skin is pressed for a predetermined time, resulting in pressure ulcers and nerve compression on the patient. was likely to occur.

In addition, when a single-layer structure filled with a large number of beads is formed as in the conventional method, there is a risk of accidental occurrence during surgery, such as dropping the surgical scalpel due to improper delivery of the surgical scalpel. In such a case, there is a possibility that air leakage will occur due to damage to the elongated bag-shaped fabric body, releasing the negative pressure and making it impossible to fix the patient's posture.

Therefore, an object of the present invention is to prevent pressure ulcers and nerve compression from occurring over a predetermined period of time without excessive pressure on the patient's skin when used, and to prevent the occurrence of sudden events during surgery. To provide a body position fixing mat capable of maintaining a fixed state of a patient's body position even if the body position is fixed.

In order to solve the above problems, in the invention of claim 1, a plurality of gas-permeable elongated bag-like fabric bodies filled with a large number of beads, and a plurality of gas-permeable elongated bag-like fabric bodies are stored. A lower layer portion having an exterior portion made of a covering material that covers in an airtight state; an upper part comprising a body;
A device for generating negative pressure is detachably attached to the exterior to suck the air inside the exterior. The elongated bag-shaped fabric body is formed to have a length dimension greater than the width dimension of the human body, and is connected in a plurality along the height direction while intersecting the height direction. The flexible bodies are each formed in the shape of an elongated plate with a length dimension larger than the dimension in the width direction of the human body, and each of the elongated bag-shaped fabric bodies corresponds to each of the elongated bag-shaped fabric bodies. Above the elongated bag-shaped fabric body, a plurality of bag-like fabric bodies are accommodated in the skin material and arranged along the height direction in a state that intersects with the height direction of the human body, without being joined to each other. The bag-shaped fabric body is made of a fabric made of woven fabric or knitted fabric, and is joined by weaving or knitting the joint portions in the width direction of each of the elongated bag-shaped fabric bodies to form an overall flat rectangular shape. In addition, the thickness dimension of the skin material is formed smaller than the thickness dimension of the covering material .

The body position fixing mat according to the present invention has a two-layer structure of a lower layer portion and an upper layer portion. In the lower layer part, a gas-permeable elongated bag-shaped fabric body filled with a large number of beads is placed in the covering material in an airtight state in the width direction of the human body lying on the back or lying thereon. It is formed continuously along. The upper layer is above the lower layer and is continuous along the width direction of the human body lying supine or lying on it, and a plurality of flat strip-shaped soft bodies are covered with a skin material. It is arranged corresponding to each compartment of the body.

The human body fixing mat according to the present invention is, for example, laid on an operating table with the upper layer facing up, and when a patient lies on his or her back, the elongated bag is placed under a load from the human body or the like. The lower layer shrinks along the length direction of the elongated bag-shaped fabric by sucking the air inside the bag-shaped fabric by the negative pressure generating device through the valve portion provided in the exterior.
As a result, according to the surface pressure of the load, the lower layer and the upper layer deform from both sides of the human body so as to conform to the surface shape of the human body and stand up, or create a wall that wraps the human body. from both sides. It should be noted that whether to stand up or wrap when deformed depends on the load from the human body or the like and the amount of protrusion (length in the width direction).

When degassed, the elongated bag-shaped fabric shrinks along the length direction, so it deforms into a lateral arc along the width direction of the patient's body, and is fixed by sandwiching the patient's body so as to wrap it from the sides. do.
In addition, the elongated bag-shaped fabric body is made of a fabric made of woven fabric or knitted fabric, and the joint portions in the width direction of each of the elongated bag-shaped fabric bodies are joined by weaving or knitting. Therefore, the plurality of elongated bag-shaped fabric bodies connected in the width direction are integrally formed by weaving or knitting the elongated bag-shaped fabric bodies themselves at the joints in the width direction without using separate threads or the like. It is

The invention according to claim 2 is characterized in that the beads have an average particle diameter in the range of 0.7 to 1.0 mm.

According to the first aspect of the invention, a plurality of gas-permeable elongated bag-shaped fabric bodies filled with a large number of beads, and a covering material that accommodates the elongated bag-shaped fabric bodies and covers them in an airtight state and a plurality of soft bodies continuously provided above the lower layer and arranged corresponding to each of the elongated bag-shaped fabric bodies and covered with a skin material. and a negative pressure generating device provided in the exterior part for sucking air inside the exterior part is detachably attached, and in a normal state, it is in a closed state and does not allow the air outside the exterior part to flow inward. The elongated bag-like fabric body and the soft body are arranged in a state of intersecting the height direction of the human body when the human body is in a supine or recumbent state. When degassed, the elongated bag-like fabric shrinks along the length direction, so that it deforms into an arc shape in cross section so as to move upward along the width direction of the patient's body. It is configured to sandwich and fix the patient's body so as to wrap it from the sides.

In the conventional posture fixing mat, the elongated bag-like fabric body is arranged along the height direction of the human body, with the human body lying on its back or lying down as a reference. In this case, since the voids of the elongated bag-shaped fabric bodies are formed along the length direction at the joints between the plurality of elongated bag-shaped fabric bodies, the existence of the gaps allows for a sufficient height direction. However, there is a problem that the fixing strength cannot be ensured.

However, in the invention according to claim 1, the elongated bag-like fabric body and the soft body are arranged in a state in which the human body is in a supine or recumbent state as a reference, and in a state in which they intersect with the height direction of the human body. Since each elongated bag-shaped fabric body can fix the patient's body along the width direction, the gaps arranged along the width direction of the patient's body interfere with fixation. Therefore, it is possible to ensure sufficient fixing strength.

In addition, since conventional body position fixing mats have a single-layer structure filled with a large number of beads, the pressure to fix the body position is partially increased, and the patient's skin and muscles are compressed, resulting in pressure ulcers. However, in the invention according to claim 1, the upper layer, which comes into direct contact with the human body when the patient is lying down, is made of a soft body, so the lower layer is Even if negative pressure acts on the human body and applies pressure to the human body, the upper layer acts to buffer the pressure on the human body and can ensure a predetermined cushioning property. It is possible to reduce the patient's pain at times, and to avoid the occurrence of pressure ulcers and nerve compression.

Furthermore, in the case of a one-layer structure filled with a large number of beads, damage to the elongated bag-like fabric may occur due to an accidental event during surgery, for example, if the surgical scalpel is dropped due to improper delivery of the surgical scalpel. There was a risk that an air leak would occur and the negative pressure would be released. Even if it is damaged, it is possible to prevent the lower layers from being affected, so that the fixed state of the patient can be maintained.

In addition, since the upper layer with the soft body is arranged separately from the lower layer where the negative pressure acts, the lower layer shrinks due to the action of the negative pressure, causing wrinkles and sagging of the exterior. Even if it occurs, wrinkles and sagging do not affect the upper layers, so it is possible to suppress the occurrence of wrinkles, etc. due to the generation of negative pressure in the upper layers as much as possible. It is possible to prevent the occurrence of pressure ulcers and nerve compression caused by wrinkles and the like resulting from long-term fixation between the patient's skin and pressure on the patient's skin.

Further, the elongated bag-shaped fabric body is made of a fabric made of woven fabric or knitted fabric, and the joint portions in the width direction of each of the elongated bag-shaped fabric bodies are joined by weaving or knitting, A plurality of elongated bag-shaped fabric bodies connected in the width direction are integrally formed by weaving or knitting the elongated bag-shaped fabric bodies themselves at joints in the width direction without using a separate thread or the like, Since it is not fixed using a separate suture thread or the like, it is possible to prevent the suture thread from being reflected in an examination using an X-ray or the like.

Furthermore, it is characterized in that it is formed in a rectangular shape as a whole in plan view, and that the thickness dimension of the skin material is formed smaller than the thickness dimension of the covering material.

Therefore, when the patient lies on his or her back, the skin material of the upper layer, which comes into contact with the patient's skin, is thinner than the covering material of the lower layer. Even if it does, it is possible to reduce the influence of the pressure on the patient's skin.

In the invention according to claim 2, since the beads have an average particle diameter in the range of 0.7 to 1.0 mm, the beads with large particle diameters have a high foaming ratio and thus have good cushioning properties. However, according to the fifth aspect of the invention, since only small-diameter beads are used, it is possible to provide a body position fixing mat with a higher fixing force. can.

Modifications of one embodiment of the body position fixing mat according to the present invention are shown in chronological order, (A) is an explanatory view of the human body before lying down or lying down, (B) is an explanatory view of the human body in a supine or lying state, (C) ) is an illustration of a human body holding state after suction.

A posture fixing mat according to the present invention will be described based on one embodiment with reference to the drawings.

As shown in FIG. 1, the body posture fixing mat 1 applies a negative pressure from a negative pressure generator or the like (not shown) when the human body P such as a patient is in a supine or recumbent state. It is configured to fix the posture of the human body P by fixing from both sides.

As shown in FIG. 2, the body posture fixing mat 1 includes a plurality of gas-permeable elongated bag-like fabric bodies B1 to B5 which are continuously arranged along the width direction and are filled with a large number of beads 3, and the elongated bag-like fabric bodies B1 to B5. A lower layer portion 4 having an exterior portion 8 made of a covering material 8a that accommodates the fabric bodies B1 to B5 and covers them in an airtight state; An upper layer portion 7 having a plurality of rectangular soft bodies 6 arranged correspondingly and covered with a skin material 5, and a negative pressure generating device 8 provided in the exterior portion for sucking the air inside the exterior portion 8 ( (not shown) is detachably mounted.

The cushion body 2 is formed of elongated bag-like fabric bodies B1 to B5 filled with a large number of beads 3 inside. Three band portions 11 extending outward in the width direction are provided along the belt portion.

Specifically, the body posture fixing mat 1 includes a lower layer 4 containing a large number of beads 3 filled in gas-permeable elongated bag-shaped fabric bodies B1 to B5 formed by weaving a knit fabric, and polyurethane. It is composed of a two-layer structure with an upper layer portion 7 including a soft body 6 formed of foam in a flat rectangular shape.

In this case, it is also possible to use a material other than polyurethane foam for the soft body 6, and any material that can ensure appropriate cushioning properties can be used.

In this embodiment, the body position fixing mat 1 is formed in a planar rectangular shape, and the five elongated bag-like fabric bodies B1 to B5 have their length direction along the width direction of the low position fixing mat 1, They are arranged in series along the length direction of the body posture fixing mat 1, and above each of the elongated bag-like fabric bodies B1 to B5, there are five soft rubber pads corresponding to each of the elongated bag-like fabric bodies B1 to B5. A body 6 is arranged and entirely covered with a skin material 5 to form an upper layer portion 7 which is joined and fixed to the lower layer portion 4 .

The material of the covering material 8a that constitutes the lower layer 4 is gas-impermeable to keep the internal gas airtight. The elongated bag-like fabric bodies B1 to B5 are formed to be gas permeable, and in the present embodiment, are formed in a cylindrical shape having an elliptical cross section so that the beads 3 can be filled inside. It is configured.
Further, in this embodiment, the soft body 6 is formed to have substantially the same width and length dimensions as the elongated bag-like fabric bodies B1 to B5, and the soft body 6 is not connected to each other in the width direction. It is housed in the skin material 5 and disposed in this state.

Therefore, when the lower layer 4 shrinks during degassing and each of the elongated bag-like fabric bodies B1 to B5 is deformed into an arc with both ends rounded upward along the length direction, each The soft body 6 is also arranged in an upwardly rounded arc similar to the lower layer 2 along with the corresponding elongated bag-shaped fabric bodies B1 to B5. In this state, the body of the patient lying on his or her back is sandwiched from both sides and fixed.

The thickness dimension of the skin material 5 forming the upper layer portion 7 is formed to be smaller than the thickness dimension of the covering material 8a forming the exterior portion 8 . As a result, the skin material 5 that comes into contact with the patient's skin when the patient lies on his or her back is formed thinner. It is configured so as to reduce the influence on the skin and the like.
In this embodiment, the thickness dimension of the skin material 5 forming the upper layer portion 7 is formed to be smaller than the thickness dimension of the skin material forming the exterior portion 8, as an example. However, the thickness dimension of the skin material 5 that constitutes the upper layer portion 7 does not have to be smaller than the thickness dimension of the skin material that constitutes the exterior portion 8 .

In addition, the elongated bag-like fabric bodies B1 to B5 are integrally formed by being woven together with a knit fabric, and the joints 2a between the elongated bag-like fabric bodies B1 to B5 are formed using separate sutures. not joined together.
Therefore, if a separate suture thread is used to suture the elongated bag-like fabric bodies B1 to B5, there is a possibility that the suture thread will appear in the image when an X-ray image is taken. However, in the present embodiment, since the joints 2a between the elongated bag-shaped fabric bodies B1 to B5 are integrally woven from the knit fabric without using suture thread, this Such a situation can be effectively avoided.
In this case, in the present embodiment, the case where the elongated bag-shaped fabric bodies B1 to B5 are integrally woven from a knit fabric has been described as an example, but if it is a knit fabric, various chemical fibers can be used. Alternatively, natural fibers can be used as materials. In addition, a fabric other than a knit fabric may be used as long as the elongated bag-shaped fabric bodies B1 to B5 can be integrally formed.

In the present embodiment, as the beads 3, for example, small-particle beads 3 having an average particle diameter in the range of 0.7 to 1.0 mm are used. In this case, in FIG. 2(D), only a part of the beads 3 is shown for convenience of explanation, and the beads 3 are actually filled with a certain amount of gap.

Large particle size beads (for example, average particle size of 4.0 to 5.0 mm) may be mixed with small particle size beads for use. Such large-diameter beads have a high foaming ratio and therefore have good cushioning properties. is used. As in the present embodiment, when only small-diameter beads are used, it is possible to provide a body posture fixing mat with greater fixing power than when large-diameter beads are used.
Moreover, beads having a particle size other than the small particle size beads or the large particle size beads may be mixed and used, and the present embodiment is not limited. Furthermore, small particle size beads and large particle size beads can also be used without being limited to the above particle size.

The belt portion 11 has a predetermined width and strength. It has a length along the existing direction and both ends protrude from the lower layer portion 4 by a predetermined length.

As a result, the mat portions (lower layer portion 4 and upper layer portion 7) of the body position fixing mat 1 can be fixed by engaging both ends of the belt portion 11 on the back side of the bed, pedestal, or the like.

Further, for example, as an emergency stretcher, it is also possible to move, relocate, transport, etc. by holding both ends of the band part 11 with a plurality of people in a supine or lying state. The length of the belt portion 11 can be adjusted, and it is optional to directly engage both ends or to provide an engaging portion (not shown) that engages with an engaged portion provided on the bed/stand. be.

The use condition of the body posture fixing mat 1 according to the present embodiment will be described below.
When using the body posture fixing mat 1 according to the present embodiment, as shown in FIGS. The patient's human body P is arranged in a direction intersecting the length direction of the fabric bodies B1 to B5 and the soft body 6, and the patient is placed supine or lying down on the body position fixing mat 1, and set on a CT scan, MRI, or an operating table. (fix).

As shown in FIG. 3(B), when the human body P lies on its back or side on the body posture fixing mat 1, the weight (load) of the human body P compresses the upper layer 7 so as to sink, and at the same time, the lower layer 4 is compressed. The beads 3 fluidly move inside the elongated bag-shaped bodies B1 to B5, and slightly deform so as to be in close contact with the surface of the human body P (for example, the back side such as the back).

Then, in this state, as shown in FIG. 3C, the hose 10 of the negative pressure generating device (not shown) is connected to the valve portion 9, and the negative pressure generating device is operated to suck the air in the exterior portion 8. , when a negative pressure is generated inside the exterior part 8, the air inside the gas-permeable elongated bag-like fabric bodies B1 to B5 and the air inside the exterior part 8 are sucked, and the exterior part 8 As the inside is evacuated, the parts of the body position fixing mat 1 protruding from the top, bottom, left, and right of the human body P stand up.
By appropriately shaping the standing portion so that both sides of the patient can be held by a caregiver, the cross section is deformed into an arc that is rounded upward, and the patient's body P is deformed from both sides. As a result, the posture of the human body P in the direction of turning over is maintained in a fixed state.

Therefore, the portions of the lower layer portion 4 and the upper layer portion 7 protruding from the human body P in accordance with the surface pressure of the load are deformed so as to follow the surface shape of the human body P, and the walls stand up or wrap around the human body P. and can maintain posture, ie fix or retain posture.

At the time of this deformation, for example, whether the human body P stands up as shown in FIG. 1 near both hands or is wrapped as shown in FIG. ).

By the way, in the case of a single-layer structure consisting of only the lower layer 4 filled with a large number of beads 3, the pressure for maintaining the body position is partially increased, which may cause bedsores and nerve compression.
On the other hand, the body position fixing mat 1 according to the present embodiment has a two-layer structure of the lower layer 4 where the negative pressure acts and the upper layer 7 where the negative pressure does not act. A good cushioning property can be ensured by the upper layer 7, the posture during surgery or radiotherapy can be easily maintained, and the occurrence of bedsores and nerve compression can be suppressed.

In addition, as in the conventional art, when the body position fixing mat is composed of a single-layer structure consisting of only the lower layer 4 filled with a large number of beads 3, an unexpected event during surgery, such as the delivery of a surgical scalpel, can be handled appropriately. If the surgical scalpel falls into the lower layer part 4 without performing the operation, air leakage may occur due to breakage of the elongated bag-like fabric body 2, and the negative pressure may be released.
On the other hand, by adopting a two-layer structure consisting of the lower layer 4 to which negative pressure is applied and the upper layer 7 which is not subjected to negative pressure, the negative pressure is applied to the lower layer 4 and the upper layer 7 is applied to the negative pressure. Therefore, it is possible to suppress the possibility that the elongated bag-like fabric body 2 is damaged, and it is possible to reduce the possibility of air leakage.

In addition, if the extension direction of the joint 2a is along the height direction of the human body P lying on its back or lying down, that is, along the direction in which the rotation fulcrum extends when both sides stand up so as to involve the human body P, the joint 2a It becomes a fulcrum of rotation, which makes it difficult to maintain the body position of the human body P. Moreover, there is a possibility that a part of the human body P may be pinched between the joints 2a when deformed due to negative pressure.

On the other hand, since the extending direction of the joint portion 2a extends in a direction orthogonal to the height direction of the human body P lying on its back or lying down, the outer periphery protruding from the human body P can be raised appropriately while following the surface of the human body P. Therefore, it is possible to avoid the risk of pinching a part of the human body P between the joints 2a when deformed due to negative pressure.

In addition, since the joint portion 2a can maintain the cylindrical shape of the elongated bag-like fabric body 2 (including compression deformation due to the load from the human body P side), the gap between the human body P and the joint portion 2a can be easily formed. Therefore, it is possible to suppress the occurrence of blood circulation disorders (for example, economy class syndrome) due to long-time surgery.

As for the beads 3, as described above, large-particle beads having an average particle size of 4.0 to 5.0 mm and small-particle beads having an average particle size in the range of 0.7 to 1.0 mm are mixed. It is also possible to provide a filled positioning mat.

The above-described embodiment is an example, and the configuration can be appropriately changed within the scope of the present invention, and the present invention is not limited to the above-described embodiment.
