Description

The present invention relates to a postural immobilizer for restraining the body.

In medical examinations such as ERCP examinations, MRI examinations, and CT examinations, if the subject's body moves during imaging, the captured image will blur, so the subject must not move during the examination. . However, the examination may take more than 30 minutes, and it is not easy for the subject to keep still during the examination. Therefore, postural immobilizers are utilized to support the subject's body so as to minimize body movement.

For example, in the posture fixing devices disclosed in Patent Documents 1 and 2, a sheet-like body support member having an internal space in which foam beads are enclosed is fixed around the subject's body with a belt or the like, and the internal space is A vacuum is created in the interior space by evacuating air from the interior space so that the foam beads are pressed together in the interior space to maintain the body support member in a contoured shape. Since the subject is supported by a body support member that maintains a shape that conforms to the subject's own body, the subject's posture is maintained even when the subject's strength is relaxed, making it possible to easily maintain the body position.

In such a body position fixing device, as shown in Patent Document 1, the body support member is fixed around the body by a belt attached to the body support member. In addition, since the size of the body varies, the length of the belt can be adjusted. The body support member is secured to the body in a snug fit.

Japanese Patent No. 5138720 JP 2006-288451 A

However, if the size of the body support member is designed to accommodate relatively large subjects, and the belt is attached to such a body support member by a belt retainer, such as a belt loop, When attempting to attach the body support to a relatively small subject, portions of the body support may overlap such that the belt loops and the belt passing therethrough are hidden behind the body support. As a result, even if the belt is tightened around the body-supporting member, the body-supporting member itself may hinder the belt from being properly tightened.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a body posture fixing device that can fix the body of a subject with a belt even for subjects with various body types.

That is, the present invention
a sheet-like body support member adapted to wrap a person's body;
a plurality of belt holding portions arranged so as to line up in the circumferential direction of the body when the body support member is worn on the body;
a belt attached to the body support member by the plurality of belt retainers for securing the body support member about the body;
with
Provided is a body position fixing tool in which belt holding parts arranged at both ends in the circumferential direction of a plurality of belt holding parts are capable of selectively releasing the holding of the belt.

Since the belt holding portions disposed at both ends of the belt holding portion can selectively release the holding of the belt, the belt holding portions are hidden behind the body support member as described above. In such a case, it is possible to remove the belt from the belt holding portion and prevent the belt from being hidden behind the body support member. As a result, even for a small person whose body support members partially overlap each other, it is possible to fix the body support member to the body in a state in which it fits snugly with the belt.

In particular,
each belt having a pair of buckles detachably connected to each other;
The belt holding portion capable of selectively releasing the holding of the belt may be a belt loop sized to allow the buckle to pass through.

A body position fixture 100 according to an embodiment of the present invention shown in FIGS. 1 and 2 mainly supports the body of a subject during an ERCP examination, an MRI examination, or a CT examination so that the subject's body does not move during the examination. It is for The body position fixture 100 includes a sheet-like body support member 102 and first to fifth belts 104a to 104e attached to the body support member 102. As shown in FIG. A plurality of belt loops (belt holders) 106a, 106b are disposed on the body support member 102, and belts 104a-104e are attached to the body support member 102 by a plurality of belt loops 106a, 106b, respectively. Each of the belts 104a-104e has a pair of buckles 108a and 108b detachably connected to each other, and the position of one buckle 108a with respect to the belts 104a-104e can be adjusted. Two arm restraints (limb restraints) 110 are attached to the central third belt 104c.

As shown in FIG. 3, the body support member 102 is a bag-like member having an internal space 112, in which foam beads 114 are enclosed. As can be seen from FIG. 1, the internal space 112 is largely partitioned into five spaces, which are not completely separated and communicate with each other through narrow passages 116 . Body support member 102 further includes an exhaust port 118 in communication with interior space 112 .

As shown in FIGS. 4 and 5, the arm restraint 110 has a mounting portion 120 and a connecting portion 122 which are formed of two band-like members formed separately. The arm restraint 110 has a cross shape in which a mounting portion 120 and a connecting portion 122 are sewn together at a central fixing portion 124 and fixed. As shown in FIGS. 6 and 7, the connecting portion 122 is folded back at a folding portion 126 adjacent to the fixing portion 124 with the mounting portion 120 and extends while facing each other. and a portion 130 . A first hook-and-loop fastener 132 is provided on the first portion 128 of the connecting portion 122 , and a second hook-and-loop fastener 134 is provided on the second portion 130 . A first hook-and-loop fastener 132 and a second hook-and-loop fastener 134 are attached with the first portion 128 and the second portion 130 extending in a direction transverse to the longitudinal axis L of a third belt (elongated external member) 104c to sandwich the belt 104c. , the connecting portion 122 is connected to the belt 104c. At this time, the first hook-and-loop fastener 132 and the second hook-and-loop fastener 134 are releasably connected to each other on both sides of the belt 104c in the direction transverse to the belt 104c, that is, in the direction of the longitudinal axis M of the connecting portion 122. As shown in FIG. The attachment position of the connecting portion 122 with respect to the belt 104c in the direction across the belt 104c can be arbitrarily changed by changing the position of sandwiching the belt 104c. In addition, since the connecting portion 122 simply sandwiches the belt 104c between the first hook-and-loop fastener 132 and the second hook-and-loop fastener 134, the belt 104c can be displaced in the direction of the longitudinal axis L of the belt 104c. ing. However, since the belt 104c in this embodiment is made of a cloth material, and the first hook-and-loop fastener 132 and the second hook-and-loop fastener 134 are loosely coupled, the connecting portion 122 is located at the longitudinal axis L with respect to the belt 104c. It does not move in the direction of , but is displaced when a person applies a slight force to the connecting portion 122 .

The mounting portion 120 of the arm restraint 110 has, as shown in FIGS. A third hook-and-loop fastener 140 is provided on the portion 136 and a fourth hook-and-loop fastener 142 is provided on the fourth portion 138 . The third hook-and-loop fastener 140 and the fourth hook-and-loop fastener 142 are arranged on surfaces opposite to each other. Furthermore, a fifth hook-and-loop fastener 144 is provided on the second portion 130 of the connecting portion 122 on the side opposite to the second hook-and-loop fastener 134 . As shown in FIG. 7, the fifth hook-and-loop fastener 144 is exposed to the outside with the connecting portion 122 connected to the belt 104c and is positioned adjacent to the fourth hook-and-loop fastener 142. It is adapted to be releasably coupled to the third hook-and-loop fastener 140 . That is, the mounting part 120 can be fitted to the circumference of the subject's arm by connecting the third hook-and-loop fastener 140 to the fourth hook-and-loop fastener 142 or the fifth hook-and-loop fastener 144 according to the thickness of the subject's arm. It is supposed to be circular in

As shown in FIG. 8, the body posture fixing device 100 is worn so as to wrap the body of the subject A lying face down on the body support member 102 . At this time, at least the portion of the subject A's arm beyond the wrist is outside the body support member 102 . After connecting the buckles 108a and 108b of the belts 104a to 104e, the belts 104a to 104e are pulled so as to change the position of the buckle 108a with respect to the belts 104a to 104e, and the lengths of the belts 104a to 104e between the buckles 108a and 108b are adjusted. By adjusting, the body support member 102 can be brought into a state in which the body of the subject A is snugly fitted. A first belt 104a is attached to the body support member 102 by five belt loops 106a, 106b arranged side by side on the body support member 102 along the circumference of the body when worn. A first belt 104a and its retaining belt loops 106a, 106b (the first set of belts and belt retainers) are arranged to lie around Subject A's arm and upper body at Subject A's upper arm position. It is Similarly, the second belt 104b is attached to the body support member 102 by five belt loops 106a, 106b arranged side by side on the body support member 102 along the circumference of the body when worn. A second belt 104b and its retaining belt loops 106a, 106b (a second set of belts and belt retainers) are positioned around Subject A's arms and upper body at Subject A's forearm position. It is By holding the arm at the upper arm position and the forearm position with the elbow sandwiched between the first belt 104a and the second belt 104b, the arm can be effectively fixed. Third through fifth belts 104c-104e are each attached to body support member 102 by three belt loops 106b, with third belt 104c positioned near subject A's waist, fourth belt 104d and fifth belt 104d. belts 104e are arranged so as to be positioned on the legs of the subject A, respectively. The body support member 102 is fixed along the body of the subject A by the five belts 104a to 104e, and the air in the internal space 112 is sucked and exhausted through the exhaust port 118, so that the internal space 112 becomes a vacuum state. The foam beads 114 are pressed against each other within the interior space 112 . As a result, the foam beads 114 are maintained in a shape that conforms to the body, and the body of the subject A is supported by the body support member 102 . In addition, the belts 104a to 104e are positioned with respect to the body support member 102 so that the buckles 108a and 108b are shifted from the center of the back of the subject A so that the buckles 108a and 108b do not interfere with imaging by MRI or the like. adjusted.

The arm restraint 110 is attached by connecting the connecting part 122 to the third belt 104c as shown in FIGS. At this time, the connecting portion 122 is attached in such a direction as to extend from the mounting portion 120 toward the leg side of the subject A. As shown in FIG. A part of the first hook-and-loop fastener 132 and the second hook-and-loop fastener 134 of the connecting portion 122 may be exposed to the outside depending on the method of connection. This prevents the exposed part from hitting the subject's arm. The wearing part 120 is worn by wrapping it around the subject A's arm in a ring shape. As described above, since the connecting portion 122 is attached to the belt 104c so as to be displaceable in the direction of the longitudinal axis L of the belt 104c, the connecting portion 122 is attached at a position away from the subject A's arm in the circumferential direction of the body. After connecting to the belt 104c, the arm restraint 110 can be displaced to the position of the arm. As a result, for example, when the belt 104c is hidden by the arm of the subject A, the connecting part 122 is connected to the belt 104c at a position where the arm does not get in the way, and then the arm restraint 110 is moved to an appropriate position. This makes it possible to easily connect the connecting portion 122 to the belt 104c. In addition, since the third hook-and-loop fastener 140 of the mounting portion 120 can be connected to the fifth hook-and-loop fastener 144 in addition to the fourth hook-and-loop fastener 142, the mounting portion 120 can be made smaller in a ring shape, which is advantageous for subjects with thin arms. It is possible to properly mount the mounting portion 120 even when the mounting portion 120 is mounted. Subject A's arm is connected to the belt 104c and restrained by the arm restraint 110 attached in this manner.

When the body position fixing device 100 is attached to a relatively small subject B, the body support members 102 may partially overlap each other as shown in FIG. 9 . Here, in the body position fixing device 100, the belt loops 106a at both ends of each of the plurality of belt loops 106a and 106b that hold the first belt 104a and the second belt 104b positioned around the upper body of the subject B are It is larger than the other belt loop 106b and has a size through which the buckles 108a and 108b can pass. Therefore, the belts 104a and 104b can be removed from the belt loops 106a at both ends through the buckles 108a and 108b. In this way, the belt loops 106a at both ends can selectively release the holding of the belts 104a and 104b, thereby releasing the holding of the belts 104a and 104b at the portion where the body support member 102 overlaps. , even when the body support member 102 overlaps, the body support member 102 can be appropriately fixed to the subject A by the belts 104a and 104b. It is not necessary that both of the belt loops 106a at both ends can release the holding of the belts 104a and 104b, and only one belt loop 106a can release the holding of the belts 104a and 104b. good too. Also, a part of the belt loop 106b that holds the third to fifth belts 104c to 104e may be configured to release the holding of the belts 104c to 104e.

As shown in FIG. 10, a body position fixing device 200 according to another embodiment of the present invention includes belt loops 206a and 206b for holding a first belt 204a and a second belt 204b. It is different from the body position fixing device 100 described above in that 206a has a large number of loop portions 207. FIG. Since the belt loops 206a at both ends have a large number of loop portions 207, it is possible to finely change the holding position through the first belt 204a and the second belt 204b according to the body size of the subject.

In an arm restraint 210 according to another embodiment of the present invention, as shown in FIGS. 11 and 12, two belt-like members constituting a mounting portion 220 and a connecting portion 222 are fixed in a T-shape. . The mounting portion 220 has a configuration similar to that of the mounting portion 120 described above. The connecting portion 222 is folded back at a first portion 228 extending from a fixing portion 224 to the mounting portion 220 and a folded portion 226 on the side opposite to the fixing portion 224 of the first portion 228 to face the first portion 228 . and a second portion 230 adapted to extend. The first hook-and-loop fastener 232 provided on the first portion 228 is arranged on the entire surface from the fixing portion 224 to the folded portion 226, but the portion arranged on the fixing portion 224 also functions as a fifth hook-and-loop fastener 244. do. That is, in a state in which the connecting portion 222 is folded back at the folding portion 226 as shown in FIG. The hook-and-loop fastener 240 can be joined to the fifth hook-and-loop fastener 244 in addition to the fourth hook-and-loop fastener 242, so that the adjustment range of the size when the mounting portion 220 is annular is widened. there is In addition, in the arm restraint device 210, when the second portion 230 is joined to the first portion 228 so that a portion of the second portion 230 protrudes from the first portion 228 beyond the mounting portion 220, the second portion 230 It is preferable that the connecting portion 222 is attached so that the second portion 230 does not protrude from the first portion 228 because there is a risk that the arm may hit the arm.

Although the embodiments of the present invention have been described above, the present invention is not limited to these embodiments. For example, an arm restraint can be used as a leg restraint. That is, the arm restraint can be a limb restraint for restraining either the upper limb or the lower limb of the subject. Also, the connecting portion of the limb restraint device may be of other connecting structure such as a snap button instead of the hook-and-loop fastener. Limb restraints are mainly described as being used in posture fixing equipment used during MRI examinations and CT examinations. It may be used to Furthermore, the structure for holding the belt is not limited to the belt loop, and a belt holding portion having other structure such as a button or hook-and-loop fastener may be used. Further, the body support member may have a structure partially or wholly made of a cushioning material such as low-resilience urethane instead of having foam beads enclosed in the internal space.
