Description

The present invention relates to a posture-holding tool and a posture-holding method for facilitating the holding of a human body position. In addition, in this specification, a person who uses a posture-retaining device is referred to as a "patient" in an explanation related to medical treatment such as epidural anesthesia, and is referred to as a "human" in other general explanations. It shall be.

As a conventional therapeutic posture holding device, for example, a cushion system for use in the treatment of various pathological conditions such as gastroesophageal reflux disease has been proposed (Patent Document 1). This therapeutic cushioning system is one that causes gastroesophageal reflux disease (GERD) most often and causes the greatest damage when the patient is sleeping, so the contents of the partially digested stomach containing acid. This is to prevent the stomach from flowing back into the esophagus, and mainly to tilt the upper body so that the head side is raised. Therefore, in the therapeutic cushion system described in Patent Document 1, the patient's back is curled up to take a lateral decubitus position, and various anesthesia such as epidural anesthesia and lumbar spinal anesthesia, or various examinations, diagnoses, and treatments are performed. It cannot be offered.

That is, conventionally, there is no posture-retaining device that stretches the muscles of the lower back by curling the patient's back and taking a lateral decubitus position. Furthermore, there is no medical position holder used for performing various anesthesia such as epidural anesthesia and lumbar spinal anesthesia, or various tests, diagnoses, and treatments.

In order to stretch the muscles of the lower back in the case of low back pain, it is effective to curl the human back and maintain the lateral decubitus posture. Furthermore, in epidural anesthesia and lumbar anesthesia, the patient's posture is very important, and the patient should be in a lateral decubitus position (epi position) with the back curled up as much as possible like a boiled shrimp on the bed in the operating room. Even after the injection needle is punctured, it is necessary to keep the posture and rest sideways for about 15 to 30 minutes. For example, if the body is twisted when curling up, the scapula will interfere and it will be difficult to make an injection, and if the scapula is not in a position to open naturally, it will be between the vertebrae of the spine. It is not possible to secure a gap. In the medical field, epidural anesthesia is abbreviated as epidural or epidural anesthesia. The posture in which the needle easily punctures is called the epi position or epi posture. Hereinafter, in the present specification, various anesthesia such as epidural anesthesia and lumbar anesthesia, or various examinations, diagnoses, and treatments are performed by curling the back in the lateral decubitus position and inserting an injection needle between the vertebrae of the spine. The postures that are easy to do are collectively called the epi position.

Therefore, epidural anesthesia and lumbar anesthesia are performed with the assistance of a nurse. The nurse asks the patient to be in a lateral decubitus position with his left or right half of his body down while assisting the patient, curling his back, bending his head forward, and holding his knees. Induce the patient to take an open posture (so-called epi-posture) between the vertebrae of the spine (spine).

Special Table 2015-506257

However, although the anesthesia time is about 15 to 30 minutes, most of the patients are elderly and it is difficult to maintain their posture on their own. Is difficult. Therefore, the current situation is that nurses hold their shoulders and knees to maintain their posture. However, there are many other things that nurses have to do, and it may be difficult for large patients and patients who have difficulty bending their backs to maintain their posture with the help of the nurse alone. Auxiliary tools that can easily maintain the posture are desired.

Furthermore, in order to shorten the anesthesia work time, even if the nurse does not guide while giving detailed explanations for taking the epi position, simple instructions such as "Lie down and hold in the crotch" With simple instructions and explanations such as "please", it is desirable to have a position assisting device that allows the patient to take the epi position by holding the position holding device and maintain that position reasonably.

The present invention has been made in response to such a demand, and an object of the present invention is to provide a posture-holding tool and a posture-holding method for making it easier to hold a posture in a lateral decubitus position by curling the back of a human.

The invention according to claim 1, wherein in order to achieve the above object, used in surgery using anesthesia, a posture retainer for causing easily hold the posture of the lateral position and hunched human, in lateral position human and write Murrell crotch portion sandwiched between the crotch of the human state attracted in the direction of the abdomen knees bent, the space is inclined in contact is mounted or face the jaws embrace suffer is the upper surface in front of the abdomen of the human It has the a Kakaekomi portion that is secured to the front of the chest, larger than the width of the portion where the width of Kakaekomi portion with the crotch and the Kakaekomi portion being adjacent is sandwiched between the crotch of the patient's crotch is, the width _{L W} of Kakaekomi portion least 30cm 100cm below Kakaekomi section height _{L 2} is 45cm from above 13cm less state, and are within the scope length _{L 1} of the crotch portion is less 30cm above 55cm, humans lateral if the crotch is in place Kome had in both arms Kakaekomi part in front of the abdomen while sandwiching between the crotch, the attitude that racking the knee rounded nature and back without disturbing the head succumb before Is inevitably taken.

Further, in the body position holder according to claim 2 , the crotch portion is thinner than the holding portion, the crotch portion has a flat plate shape, the holding portion has a barrel shape or a columnar shape, and the central position of the holding portion. from the center of the crotch portion is to be located away in a direction perpendicular to the plane perpendicular to the axis of Kakaekomi portion.

Further, the body position holder according to claim 3 is characterized in that the crotch portion and the holding portion are integrated.
Further, the posture-holding tool according to claim 4 is characterized in that the crotch portion and the holding portion are separate bodies and are separably connected.

Further, the body position holder according to claim 5 is characterized in that an arm pulling portion is provided at least on the bed-side surface of the portion of the holding portion held by a human with both arms.

Further, the body position holder according to claim 6 is characterized in that the arm pulling portion is composed of a layer of low resilience foam provided at least on the outermost peripheral layer of the holding portion.

The posture-holding device according to claim 1 is such that when a human is in a lateral decubitus position and the crotch is sandwiched between the crotch and the holding portion is held in front of the human abdomen with both hands, the back is naturally curled up and the head is raised. Bend forward and hold your knees. In other words, the so-called epi position is taken, in which the scapula expands and the space between the vertebrae of the spine opens. Moreover, even if the caregiver or the nurse does not support the patient by holding the shoulder and buttocks, the human body can easily fix the position by the human body by hugging the position holder. Therefore, the human / patient can secure and fix the epi position (puncture position) by himself / herself.

In addition, by using this position-retaining device, it is not necessary for the nurse to explain in detail how to take the epi-position and to guide the patient, and it is expected that the injection insertion time will be shortened. Moreover, the patient's anxiety can be alleviated by holding the patient in a position-retaining device while injecting an injection such as epidural anesthesia or lumbar anesthesia.

Further, according to the posture-holding tool according to claim 2, if the human is in the lateral decubitus position and holds the holding portion in front of the human abdomen with both hands while sandwiching the crotch between the crotch, the human holds the holding portion. At that time, the angle θc formed by the tangent line passing through the intersection of the line connecting the axis of the holding part and the center of the human body and the outer peripheral surface of the holding part and the shoulder blade is maintained within the range of 45 ° or more and 80 ° or less. with the following 45 ° 1 ° or an angle θa which is defined between the center B ₁ and the knee joint plane center B ₂ and the line connecting the is orthogonal to the axis of the crotch portion of the (axis orthogonal plane) a hip Since the posture that falls within the range of is naturally taken, the so-called epi position is taken. At the same time, you can effectively stretch your lower back muscles.

Further, according to the invention of claim 2 , since the center of the crotch is located at a position perpendicular to the plane perpendicular to the axis of the holding portion from the center position of the holding portion, the front of the center of the patient's body. It is possible to take a lateral decubitus position without twisting the spinal column by holding the position holder in the crotch while sandwiching it between the crotch. Furthermore, since the crotch part is perpendicular to the center position of the holding part, there is no left-right direction when using it, and it can be used from either side, which further saves the trouble of explanation.

In addition, when the holding part and the crotch part are integrated, even if the patient holds the crotch strongly, there is a risk that the holding part and the crotch part may be spaced apart or stretched. Since there is no such thing, I can keep the epi position with my back curled up.

In addition, if at least the part of the holding part that comes into contact with the patient's body is provided with a missing part, the arm is not pinched and pressed between the bed and the posture holder, so that the arm may become numb. There is little to do.

Further, when the pull-out portion is composed of at least a layer of low-resilience foam provided on the outermost layer of the holding portion, the low-resilience elasticity is low regardless of which side of the posture holder is turned down. The subduction of the foam layer prevents the arm from being pinched and pressed between the bed and the position holder, so the arm is less likely to become numb.

Hereinafter, the configuration of the present invention will be described in detail based on the embodiments shown in the drawings.

1 to 8 show an example of an embodiment of the posture holder of the present invention. In this posture holder 1, the patient himself takes a posture in which the back is curled up to secure a gap between the vertebrae of the spine, that is, the so-called epi position, mainly during epidural anesthesia or lumbar anesthesia. It is designed so that it can be collected and maintained without the assistance of the patient. The crotch portion 2 and the holding portion 3 are adjacent to each other, and the holding portion 3 is formed larger than the crotch portion 2. In the case of the present embodiment, a columnar holding portion 3 having a size that allows the patient to hold both hands together and a plate-shaped crotch having a thickness that is thinner than the holding portion 3 and can be sandwiched between the crotch. It has a part 2.

Here, the length L ₁ of the crotch portion 2 is preferably must be sufficiently long to be sandwiched between the crotch of the patient, is not preferable in order to better hold the posture too short, too long It is not preferable to create a situation where you have to take a posture of inevitably curling your back. The length L ₁ of the crotch portion 2 of Positions holder 1 according to the present embodiment, taking into account the fact that children from adults, young persons from the elderly, such as men and women, the human patients of various age, sex, use Then, for example, it is preferably about 300 mm to 550 mm. Preferably, when the crotch portion 2 is sandwiched between the crotch of the patient, the length is such that the tip of the crotch portion 2 slightly protrudes from the crotch. Of course, even if the length is such that the tip of the crotch 2 protrudes greatly from the crotch when sandwiched between the patient's crotch, the holding portion 3 touches the front surface of the thigh (quadriceps), or There is no particular problem if the holding portion 2 is arranged in front of the abdomen of the patient and used so as to hold the boundary portion between the holding portion 3 and the crotch portion 2 near the front surface of the thigh.

On the other hand, even Kakaekomi unit 3, similarly, is preferably must be sufficiently long L ₂ to create a situation where the Kakaekomi portion 3 is Kakaekoma in front of the patient's abdomen, the attitude saddled be too short (low) It becomes difficult to maintain, and it is not preferable to create a situation in which the posture of curling the back is inevitably taken even if it is too long (high). That is, the length L ₂ of the holding portion 3 inevitably takes a posture of curling the back when holding the holding portion 3, and the posture can be maintained reasonably for at least 15 to 30 minutes. It is a length that can naturally create a holding position suitable for. _{Considering that the length L 2} of the holding portion 3 of the posture holder 1 according to the present embodiment is used by humans / patients of various ages / genders such as adults to children, elderly to young people, men and women. Then, for example, it is preferably about 130 mm to 450 mm.

That is, the total length L of the posture holder 1 (= length L _{1 of the crotch part 2 + length L 2} of the holding part 3) is, for example, as shown in FIG. A posture in which the back is curled so that the space between the vertebral bones is opened and the head is bent forward to hold the knee. It is preferable that the length is located in front of the abdomen of the body, and for example, it is a length substantially corresponding to the length between the back surface of the thigh and the chest. Specifically, as a result of research, trial production, and experiment by the present inventors, in the case of the posture holder as shown in FIG. 9, the lengths L ₁ and L ₂ of the crotch portion 2 and the holding portion 3 are the objects to be used. Based on the sum of the length of the patient's abdomen and the thickness of the thigh (distance between the front and back of the thigh) in the epi position of the patient with the standard physique, the length is equal to or greater than that and not too long. For example, assuming a Japanese adult male with a standard physique, the diameter (width) L _w of the holding portion 3 is 340 mm, and the height L ₂ of the holding portion 3 is 180 mm. As an example, the length L ₁ of the crotch portion 2 is 320 mm, and the thickness of the crotch portion 2 is 70 mm. Although not shown, the tip side of the crotch part 2, that is, the part protruding from the crotch when sandwiched between the patient's crotch, intersects the plate-shaped crotch part 2 and is on the back of the thigh. An overhanging portion to be addressed may be provided. In this case, since the overhanging portion is addressed to the back of the thigh, it serves as a rough guide for the position of the crotch 2 sandwiched between the patient's crotch, so that the holding portion 3 is inevitably in front of the patient's abdomen. Will be placed.

In the case of the present embodiment, the holding portion 3 is formed as a columnar shape having a thickness (diameter) having a margin for the hands to be assembled in the holding state. In this case, even an elderly person with a weak gripping force can easily maintain his / her posture by holding the holding portion 3 and folding his / her hands or grasping one wrist with the other hand. _{The diameter (width) L w} of the holding portion 3 of the posture holder 1 according to the present embodiment shall be used by humans / patients of various ages / genders such as adults to children, elderly to young people, men and women. In consideration of, for example, it is preferably about 30 cm to 100 cm.

Here, in the case of the present embodiment, the holding portion 3 has a columnar shape having a height corresponding to the abdominal length of the patient, but the holding portion 3 is not particularly limited to this and is suitable for being held by the patient. As long as it is a lump of a different shape and size, it may be a columnar object having any cross-sectional shape, for example, a barrel-shaped object, a polygonal columnar object such as an octagon or a hexagon, or an elliptical columnar object. _{Further, the length L 2} of the holding portion 3 is also a posture in which a space is secured in front of the chest so that the chin is placed on the upper surface of the holding portion 3 or the face is in contact with the holding portion 3 when the holding portion 3 is held in front of the abdomen. Anything that acts like a hook to catch your arm in order to keep your body. _{That is, the length L 2} of the holding portion 3 is the length of the patient's abdomen in the epi position of the patient of the standard physique to be used, as long as the above-mentioned space and the function as a hook can be secured. Regardless, it may be longer or shorter than the abdominal length. In the case of this embodiment, the holding portion 3 is formed in a columnar shape and has a height of about the abdomen of the patient, so that the head hits the holding portion 3 and the forward bending is hindered when the knee is held in a posture. In addition to making sure that there is no swelling, the spine is naturally bent so that the epi position can be taken by having to bend down to hold the holding part 3 in front of the abdomen.

On the other hand, if the crotch portion 2 is too thick, the patient's crotch segment and pelvis may open and easily roll on his back, making it difficult to maintain a lateral decubitus posture. For example, when the holding portion 3 and the crotch portion 2 have a cylindrical shape having the same thickness, the posture in the lateral decubitus position is not stable. On the other hand, if the thickness and thickness of the crotch 2 is too thin, extra force is required to pinch it between the patient's crotch, and it becomes difficult to pinch it, especially in the case of elderly people with thin thighs. It will not be easy to keep. Therefore, the thickness of the crotch portion 2 is preferably within a range in which an extra force is not required to sandwich the crotch portion 2 and the force acts in the direction in which the patient's crotch and pelvis close inward. In this case, it becomes easy to maintain the patient's lateral decubitus position. That is, the size relationship between the holding portion 3 and the crotch portion 2 is preferably that the holding portion 3> the crotch portion 2, more preferably the holding portion 3 >> the crotch portion 2, and most preferably the holding portion further. The planar shape of the crotch portion 2 is circular, and the planar shape of the crotch portion 2 is flat. In this case, the crotch portion 2 can be easily pinched and the lateral decubitus position can be easily maintained. Further, a transition portion 8 addressed to the front surface of the thigh (quadriceps femoris) is formed at the boundary portion of the crotch portion 2 with the holding portion 3. The transition portion 8 is formed, for example, on a slope.

In the case of the present embodiment, the crotch portion 2 is formed in a flat plate shape as shown in FIGS. 1, 5 and 6, but the present invention is not particularly limited to this, and the crotch portion 2 is sandwiched between the crotch of the patient. As long as the hip joint and the pelvis do not open widely when the hip joint and the pelvis are opened, a columnar object having a cross-sectional shape such as an ellipse, a circle, a rectangle, or a polygon can be used.

In the case of the present embodiment, the holding portion 3 and the crotch portion 2 are made of a separately molded foaming cushion 6, and are integrated into one mass and then one bag-shaped cover (cyst / sac). Body) covered with 5. By integrating the holding portion 3 and the crotch portion 2, the positional relationship between the holding portion 3 and the crotch portion 2 is always maintained, so that the shape can be further stabilized. It should be noted that the holding portion 3 and the crotch portion 2 do not have to be housed in the bag-shaped cover 5 after the two lumps of foamed plastic blocks constituting them are pre-bonded with an adhesive or the like to form one lump. Depending on the case, the two lumps may be housed in one bag-shaped cover 5 to form one lump.

As the bag-shaped cover 5, it is preferable to use a waterproof fabric that is soft to the touch and has elasticity, but the bag-shaped cover 5 is not limited to a specific material. In the case of the position-retaining device of the present embodiment for the purpose of maintaining the position of the patient during epidural anesthesia or lumbar anesthesia, even if the patient who is almost naked with only the surgical gown holds the position-retaining device, it is cold. It is preferable to use a material that does not feel anesthesia, for example, polyester. In this case, it is comfortable to use because it follows the deformation of the block of the holding portion 3 or the block of the crotch portion 2 composed of the foamable cushion 6 inside. Further, since it is a preferable condition in the present invention to make it difficult to feel cold, but it is not an essential condition, the material used is not limited to polyester, but synthetic fibers such as nylon, synthetic resin such as polypropylene, or alcohol cleaning. Artificial leather, synthetic leather, and natural fibers such as cotton may also be used. The bag-shaped cover 5 of the present embodiment is composed of an upper cover 5b that occupies most of the holding portion 3 and a lower cover 5a that occupies a part of the holding portion 3 and the entire crotch portion 2 and goes around. It is integrated so that it can be opened and closed by the fastener 4.

Further, it is preferable that the overall shape of the body position holder 1 is symmetrical by arranging the center of the crotch portion 2 at the center of the holding portion 3. In this case, there is no left-right direction when using it, and it can be used from either side. Therefore, the explanation of how to use can be further simplified accordingly. In addition, the posture holder in front of the center of the patient's body is held between the crotch, and the spinal column can be in the lateral decubitus position without being distorted and twisted. Of course, the posture holder 1 is not limited to a symmetrical shape, and may be formed in an asymmetrical shape in some cases.

Here, as the foamable cushion 6, it is preferable to use foamed plastic such as soft plastic foam or semi-rigid plastic foam, and more preferably soft plastic foam is used. Here, examples of the soft plastic foam include a flexible polyurethane foam made of polyurethane (PUR) as a raw material, a soft polyvinyl chloride foam made of polyvinyl chloride (PVC) as a raw material, a rubber foam, and the like. Among them, air bubbles communicate with each other. However, it is preferable to use a soft polyurethane foam that is soft and resilient. Examples of the semi-rigid plastic foam include polyethylene foam made from polyethylene (PE) and polyvinyl chloride foam.

Further, the holding portion 3 and the crotch portion 2 may be composed of only the above-mentioned foamable cushion 6, but at least the portion that comes into contact with the body is a soft and highly restorative low-resilience cushioning material such as low-resilience urethane foam. It may be covered with 7. In particular, it is preferable to cover the outside of the holding portion 3 around which the arm is rotated with a low-resilience urethane foam 7 in order to prevent the arm from being pressed against the bed. As a result, the surface of the body position holder, particularly the holding portion 3, is softly sunk, so that the holding portion 3 is easily held and the arm turned under the holding portion 3 is less likely to be pressed against the bed and become numb. Therefore, in the case of the posture holder 1 of the present embodiment, the flexible polyurethane foam 6 is composed of the low-resilience urethane foam 7 arranged around the flexible polyurethane foam 6 and at least the portion touching the patient's body, and the bag-shaped cover 5 surrounding them. Has been done.

According to Positions holder 1 configured as described above, as shown in FIG. 9, the abdomen while sandwiching the crotch portion 2 patient A is turned lateral position between the thigh A ₁ (between the crotch) if Kakaekome the Kakaekomi part 3 in front of the a ₂ in both the arm a _3, the head a ₅ took racking the knee rounded nature and back a ₆ without interfering with the bow before the attitude, the so-called epi Positions Can be taken. Moreover, by holding the holding portion 3, the posture in which the shoulder blades are expanded can be taken, and even an elderly person whose gripping force is weak can be maintained without difficulty. That is, it is possible to naturally take a lateral decubitus position in which the spine is bent by the patient's own force and the injection needle can easily puncture between the vertebrae of the spine, that is, the epi position holding the knee, and that position can be taken. It can be maintained reasonably. Furthermore, the patient can give a sense of security by hugging the body position holder 1. Further, even if the patient strongly holds the posture holder 1, there is no possibility that a gap or an increase in the gap between the holding portion 3 and the crotch portion 2 is maintained, so that the epi position can be maintained. In the figure, reference numeral A ₄ is a hand, A ₇ is the front _{surface of the thigh, and A 8} is the back surface of the thigh.

Moreover, humans seem to have a habit of trying to hold the part with the largest diameter when trying to hold an object, and even if they do not explain the part to hold, they naturally hold the crotch 2 on the thigh. sandwiched between parts a ₁ (between the crotch) would racking relatively large Kakaekomi unit 3 in front of the abdomen a _2. And since the position to hold is _{in front of the abdomen A 2} near the crotch 2 (by sandwiching it between the crotch and holding it in front of the abdomen), the epi position with the spine bent naturally will be taken by itself. .. Therefore, it is considered that the explanation time of how to take the epiposition can be shortened. For example, with a simple instruction / explanation such as "Lie down and hold it in your crotch" to the patient, the patient himself holds the position holder and takes the epi position himself, and takes that position. You can expect to keep it reasonably.

FIG. 15 schematically shows the state of the skeleton when the posture holder according to the first embodiment is used by a human. When the human / patient A holds the holding portion 3, _{the position of the scapula B 3} is illustrated in FIG. 15 (c). At this time, the scapula B ₃ expands in the direction of the arrow in FIG. 15 (b). Here, forms a tangent c and scapula B ₃ through the intersection of the outer peripheral surface of the line and Kakaekomi portion 3 connecting the median body of the axial center and the patient A in the axial That Kakaekomi portion 3 of Positions holder 1 The angle θc is preferably 45 ° or more and 80 ° or less (see FIG. 15C). At this time, the scapula of the patient holding the holding portion 3 is expanded in a sustainable state without difficulty. _{In addition, the width L W} of the holding portion 3 required to expand the shoulder blade of the posture holder 1 according to the present embodiment has various ages and genders such as adults to children, elderly to young people, men and women. Considering that it is used by humans and patients, it is desirable that it is, for example, 30 cm or more and 100 cm or less. In this case, the above-mentioned angle θc can be maintained at 45 ° or more and 80 ° or less. Furthermore, while sandwiching between the crotch portion 2 of the thigh A ₁ (between the crotch), if Hikitsukere center B ₂ of the knee joint in the direction of Kakaekomi portion 3 (the direction of the arrow shown in FIG. 15 (a) ), It is possible to maintain the epidural position in which epidural anesthesia is easy, that is, the back is curled up in the lateral decubitus position and the injection needle is easily punctured between the vertebrae of the spine. Here, the _{angle formed by the line connecting the center B 1} of the hip joint and the center B _{2 of the} knee joint between the axis of the posture holder 1, that is, the plane (orthogonal plane) a orthogonal to the axis of the hip joint 2. It is desirable that θa is 1 ° or more and 45 ° or less. At this time, it the length L ₁ of the crotch portion 2 is short, by taking a posture sandwiching the crotch portion 2 at the knee, the orientation to attract naturally in the direction of Kakaekomi portion 3 the knee. The length L ₁ of the crotch portion 2 of Positions holder 1 can take such a posture, taking into account the fact that children from adults, young persons from the elderly, such as men and women, the human patients of various age, sex, use Then, for example, it is set to about 300 mm to 550 mm. Therefore, considering that the total length L of the posture holder 1 according to the present embodiment is used by humans / patients of various ages / genders such as adults to children, elderly to young people, men and women, etc. For example, it is desirable that it is 43 cm or more and 100 cm or less.

Further, if the crotch part 2 is in the center of the holding part 3, the body can take a straight posture when the crotch part 2 is sandwiched between the crotch and held, and the spinal column can be taken in a lateral decubitus position without twisting. can. Further, when the outside is covered with the low-resilience urethane foam 7, the stability of the sideways posture can be improved and the arm can be prevented from being pressed against the body. Of course, patients have different physiques, and children and adults have different sizes to carry. Therefore, it is preferable to prepare a plurality of types of body position holders according to the patient to be used.

Further, FIGS. 10 and 11 show another embodiment (second embodiment). In the posture holding tool 1 according to this embodiment, the holding portion 3 and the crotch portion 2 are configured as two independent blocks, and are separably connected by a detachable connecting means such as a hook-and-loop fastener. For example, the holding portion 3 and the crotch portion 2 are each composed of a block (not shown) composed of an effervescent cushion and covers 5a and 5b wrapping around the block, and the holding portion 3 and the crotch of each of the covers 5a and 5b. It is separably connected by a detachable connecting means 11 such as a pair of hook-and-loop fasteners sewn on the abutting surface with the portion 2. In this case, if necessary, the connection point between the holding portion 3 and the crotch portion 2 may be shifted to eccentric the position of the crotch portion 2 with respect to the plane passing through the center of the disc-shaped holding portion 3 and the center of the patient. can. As a result, the crotch portion 2 is positively offset and connected to the center of the holding portion 3 against the pathological bending of the spine of a patient with a deformed spine, for example, a patient with scoliosis. It is possible to adjust according to the deviation between the holding position and the sandwiching position between the crotch.

Further, since the holding portion 3 and the crotch portion 2 can be separated, it is easy to store the crotch portion 2 without taking up a storage space by separating the holding portion 3 and the crotch portion 2 when not in use. At the same time, it becomes easier to secure a storage space.

Further, since the crotch portion 2 and the holding portion 3 can be separated, the holding portion 3 can be replaced according to the physique of the patient and the like. For example, if the crotch part 2 is shared and only the holding part 3 is prepared in a plurality of types according to the physique of the patient, the optimum holding part 3 according to the physique of the patient can be connected to the crotch part 2 for use. Can be done. For example, by replacing the shared crotch part 2 with an appropriately selected one from a plurality of holding parts 3 having different sizes or shapes, it can be used as a cushion for adult men, a cushion for adult women, a cushion for children, and the like. It may be exchanged with a holding portion 3 having a different size such as S, M, L, LL or the like.

Further, FIG. 12 shows another embodiment (third embodiment). The body position holder 1 according to this embodiment is provided with an arm pulling portion 12 in the holding portion 3. The arm pulling portion 12 is a space through which the arm below the body passes when the patient is in the lateral decubitus position, and is formed by a half-moon-shaped notch / step portion in the case of the present embodiment. Due to the presence of the arm pulling portion 12, the shoulder or upper arm under the patient in the lateral decubitus position is not pinched between the holding portion 3 and the bed and is not pressed. Therefore, it is possible to prevent the shoulders and arms from becoming numb when the anesthetic is injected for about 15 to 30 minutes. The holding portion 3 and the crotch portion 2 may be configured as one block as shown in the embodiment shown in FIG. 1, or two independent blocks as shown in the embodiments shown in FIGS. 10 and 11. It may be detachably connected by a detachable connecting means such as a hook-and-loop fastener.

Further, FIG. 13 shows another embodiment (fourth embodiment). The posture-holding tool according to this embodiment is a modified example of the holding portion 3 including the half-moon-shaped arm pulling portion 12 in the third embodiment shown in FIG. In this embodiment, the relief portion 12 is a crescent-shaped notch in order to form the holding portion 3 having a shape close to a circle.

Further, FIG. 14 shows another embodiment (fifth embodiment). Similar to the first embodiment of FIG. 1, the body position holder according to this embodiment is formed by forming the holding portion 3 and the crotch portion 2 into an inseparable integrated block of the holding portion 3. On the upper side (the end on the anti-crotch 2 side), notches and steps are provided in a ring shape over the entire circumference so that there is a gap between the operating table and the arm so that the shoulder and upper arm are not pressed. A punched portion 12 is formed. For this reason, in a patient who takes a lateral decubitus position by passing both arms through the arm pulling portion 12 and holding the inner holding portion 3, the shoulder or upper arm under the holding portion 3 is between the bed and the holding portion 3. Since it is not pinched, it is possible to prevent the shoulders and arms from becoming numb when injecting the anesthetic for about 30 minutes. In the case of this embodiment, since the shape is symmetrical, it is possible to eliminate the directionality in use.

The above-described embodiment is an example of a preferred embodiment of the present invention, but the present invention is not limited to this, and various modifications can be performed without departing from the gist of the present invention. For example, in the above-described embodiment, the holding portion 3 and the crotch portion 2 integrally molded with a foamable cushion material such as soft or semi-hard urethane foam are wrapped with a bag-shaped cover 5, but the present invention is particularly limited. It's not a thing. For example, the whole or a part of the posture holder 1 may be formed into a sac shape that is inflated by injecting a fluid such as compressed air or a liquid. Fluid In particular, when using a liquid, it can be easily heated with an incubator, so even if a patient who is almost naked with a surgical gown is hugging, the temperature is raised to a comfortable temperature and the temperature is raised. Can be maintained. Further, if the bag structure is inflated with the fluid to be injected, it is easy to make it disposable and hygienic.

In the case of the above-described embodiment, the body position holder 1 is composed of an effervescent cushion 6 and a bag-shaped cover 5 that encloses them. The bag-shaped cover 5 is used as needed, but in some cases, even if it is not used, there is no problem in basic performance. The bag-shaped cover 5 is mainly adopted from the viewpoint of hygiene and touch, and is not particularly required for securing and fixing the epi position. For example, when the crotch portion 2 and the holding portion 3 are integrally molded with closed-cell urethane foam having a high heat insulating property, even if the crotch portion 2 and the holding portion 3 are integrally molded with a bag-shaped cover 5, a patient who is almost naked only with a surgical gown may be present. It is also hygienic because it does not feel cold even when touched directly and can be easily washed.

In addition, the body position holder 1 may incorporate a core material in some cases. For example, a block is formed by covering a core material (including a hollow core material) composed of non-foamable plastic, hard foamed plastic, plywood, metal, etc. with foamed plastic such as urethane foam to form a bag-shaped cover. It may be covered with 5. According to this structure, the core material maintains the shape of the body position holder, so that the posture is stable. Further, the core material may be provided so as to extend over both the crotch portion 2 and the holding portion 3, but may be provided only on one of them, for example, the crotch portion 2.

Further, depending on the case, the body position holder 1 may be entirely made of a hard material or a semi-hard material. In this case, since the form as the body position holder is not deformed, the body position of the epi is unlikely to collapse. However, it is preferable that the portion of the posture holder 1 that comes into contact with the patient's body is made of a material that is soft and has abundant cushioning and resilience, in order to make it easy to hold and not to cause pain in the joint portion. Therefore, even if the posture holder 1 is made of a hard material or a semi-hard material, a member that comes into soft contact, for example, a low-resilience urethane foam, is provided only in the portion where the inside of the knee of the crotch portion 2 comes into contact with the vicinity. It is desirable to stick it on the surface to prevent the knee from getting hurt. Further, it is preferable to cover the portion of the holding portion 3 that is held by the patient, at least the peripheral surface portion, with a member that softly contacts, for example, a low-resilience urethane foam.

Further, although not shown, a felt sheet material or the like can be temporarily attached to the surface of the part of the bag-shaped cover 5 where the patient's face or the like touches, and the other part where the body touches, if necessary. Therefore, the felt sheet material may be replaced each time the posture holder is used. For example, the male side of the hook-and-loop fastener may be sewn on a part or the entire surface of the cover so that the felt sheet material can be detachably attached. It can be made hygienic by disposing of the felt sheet material and making it disposable.

Further, in the above-described embodiment, the holding portion 3 is held by the patient with both hands and has a thickness sufficient to hold the patient with both hands and to hold one wrist. The present invention is not particularly limited to this, and for example, as shown in FIGS. 10 to 12, one or two or more fixing bands 10 may be provided on the peripheral surface of the barrel-shaped holding portion 3. By submerging the user's (patient's) hand in the fixing band 10 to fix the arm or by grasping the fixing band 10, the position holder is used so that the arm holding the holding portion 3 does not separate. .. The fixing band 10 can also be used for transportation when it is stored.

Further, a mechanism (not shown) for evaporating the scent component may be provided in the holding portion 3, particularly in the place where the face and the head of the top thereof are brought close to each other. For example, it can be expected to suppress the anxiety of the patient by evaporating a calming scent.

In the above examples, the position holder of the present invention is used to allow the patient to take a lateral decubitus position with the back curled up so that the injection needle can easily pierce between the vertebrae of the spine. Although the case has been described, the posture-retaining device of the present invention can also be used to stretch the muscles of the lower back in order to maintain the health of the elderly and prevent back pain. In the above-described embodiment, a posture-holding method in which a human holds the posture-holding tool 1 illustrated in FIGS. However, the present invention is not particularly limited to this, and is not limited to the posture holding jigs of various embodiments as illustrated in FIGS. Needless to say, the above-mentioned posture-holding method can be performed as long as the scapula can be expanded and the back can be curled up and maintained in a lateral decubitus position.
