Description

[0001]
BACKGROUND OF THE INVENTION
The present invention is used for medical devices such as an X-ray diagnostic apparatus, an X-ray CT apparatus, an MRI apparatus, a nuclear medicine diagnostic apparatus, a calculus crushing apparatus, and a thermal treatment apparatus, and is used to fix a subject to a bed. Relates to the device.
[0002]
[Prior art]
As a conventional example of such a device, there is a patient placement table device described in Japanese Utility Model Laid-Open No. 6-74107. This conventional example is for eliminating the disadvantage of the conventional apparatus that the entire table must be exchanged. This conventional example will be described with reference to FIGS. 1 is a cross-sectional view, and FIG. 2 is a plan view. A base rail 12 having a receiving portion is fixed to both sides (left and right side portions) using an adhesive or the like along a longitudinal direction of a cradle (bed top plate) 2 on which a patient is placed. The fitting portion 14 of the attachment rail 13 is inserted into the receiving portion of the base rail 12 from one end in the longitudinal direction as shown in FIG. The fitting portion 14 has a ball shape. Thereafter, both ends of the fitting portion 14 of the attachment rail 13 are locked to the base rail 12 by the stopper 15. The stopper 15 can be easily fixed or released, and the attachment rail 13 can be easily installed or removed from the base rail 12. The attachment rail 13 is made of a flexible material.
[0003]
The attachment rail 13 is also provided with a receiving portion, and the fitting portion 11 of the strap 4 for fixing the patient is similarly fitted therein. The fitting part 11 also has a ball shape. For this reason, the strap 4 is slidable along the attachment rail 13. Thereby, a patient can be fixed at an arbitrary position in the body axis direction. The strap 4 also has a belt portion 10, and the tip of the belt portion 10 is bonded to the belt portion of the other strap 4 with a detachable adhesive tape such as a magic tape.
[0004]
The strap 4 is removed from the attachment rail 13 when the patient is not fixed. Therefore, when the patient is fixed, first, the fitting portion 11 of the strap 4 is slid into the receiving portion of the attachment rail 13 and inserted. At this time, the contact object of the fitting portion 11 of the strap 4 is the receiving portion of the attachment rail 13. The contact object when the strap 4 is wound around the subject is also the attachment rail 13. And if these contacts become frequent, the attachment rail 13, especially the receiving part will be damaged. When the attachment rail 13 is damaged, the stopper 15 is removed and the attachment rail 13 is removed from the base rail 11 and replaced with a new one. Therefore, when the attachment rail 13 is damaged, it is not necessary to replace the entire cradle 2.
[0005]
Thus, in this conventional example, by attaching the strap 4 to the cradle 2 via the attachment rail 13, damage to the base rail 12 fixed to the cradle 2 can be avoided. Without the attachment rail 13, the base rail 12 is damaged and the entire cradle 2 to which the base rail 12 is fixed must be replaced.
[0006]
[Problems to be solved by the invention]
However, even in the above-described conventional example in which the attachment rail 13 is provided, there is no guarantee that damage to the base rail 12 can be avoided. Since the attachment rail 13 is flexible, it hangs down while the strap 4 is removed, and the possibility that the stretcher or the strap 4 contacts the base rail 12 and the base rail 12 is damaged cannot be denied. If the base rail 12 is damaged, the entire cradle must be replaced, which is a heavy financial burden. Furthermore, since the base rail 12 cannot be removed, it cannot be replaced even when it is dirty, which is problematic in terms of hygiene.
[0007]
Furthermore, in the above-described conventional example, the strap 4 and the attachment rail 13 are fitted and the attachment rail 13 and the base rail 12 are fitted using a ball-shaped receiving portion. The ball shape does not generate any resistance against the pulling force, and there is a disadvantage that the fitting portion of the ball shape is easily detached. In order to make it difficult to come off, it is necessary to enlarge the sphere, but when it becomes large, it is difficult to handle, and the amount of X-ray absorption increases, and a medical diagnostic apparatus using X-rays such as an X-ray diagnostic apparatus and an X-ray CT apparatus It will not be usable.
[0008]
As described above, in the conventional object fixing device, it is not possible to replace only damaged parts, and there is a possibility that the whole must be replaced, and the strap and the attachment rail, or the attachment rail and the base rail. There is a drawback that the fitting part is easily disengaged.
[0009]
An object of the present invention is to provide a subject fixing apparatus that can replace only damaged parts and does not require replacement of the entire fixing base.
[0010]
Another object of the present invention is to provide a subject fixing device in which a strap as a fixture is not easily detached.

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of a subject fixing apparatus according to the present invention will be described below with reference to the drawings.
[0024]
FIG. 3 is a schematic diagram showing the configuration of the subject fixing apparatus according to the first embodiment of the present invention. Here, an example applied to a bed apparatus of an X-ray CT apparatus will be described. A top plate 32 on which a subject (not shown) is placed is provided on the bed apparatus 30. Loop tapes 34 having piles are adhered and fixed to the upper and lower surfaces of both sides (left and right sides) of the top plate 32 at three locations along the longitudinal direction, a total of six locations, as shown in FIG. . The loop tape 34 on the top surface of the top plate 32 is a mat 36 mounted on the top plate 32 (the bottom surface of the end portion of the mat 36 is provided with a hook tape 38 that is detachably bonded to the loop tape 34). The mat 36 is bonded and fixed on the top plate 32. The loop tape 34 and the hook tape 38 constitute a detachable adhesive tape called a so-called magic tape. The bonding with the mat 36 is not an essential requirement of the present invention, and the loop tape 34 may be bonded only to the lower surface of the top plate 32. The fixing of the loop tape 34 to the top plate 32 is not limited to an adhesive, and a double-sided tape, a hook or the like may be used.
[0025]
A flexible attachment belt 42 (a hook tape 40 that is detachably attached to the loop tape 34 is also provided) is bonded and fixed to the loop tape 34 on the lower surface of the top plate 32. The attachment belt 42 may be removed from the top board 32 except when the subject is fixed to the top board 32. By doing so, damage to the attachment bell 42 can be prevented. However, since the attachment belt 42 is fixed to the top plate 32 using a detachable adhesive tape, even if it is damaged, only the attachment belt 42 can be replaced, and there is no need to replace the entire top plate. This has not only a cost point but also a hygiene effect by cleaning and replacing when dirty. The attachment belt 42 is detachable from the top plate 32 and can be easily replaced. Therefore, it is not always necessary to remove the attachment belt 42 from the top plate 32 except when the subject is fixed to the top plate 32.
[0026]
A receiving portion 44 is provided at the tip of the attachment belt 42, and a fitting portion 48 at one end of the fixed belt 46 is fitted into the receiving portion 44. The fitting portion 48 has a hook shape, and the receiving portion 44 has a corresponding shape. For this reason, when a force in the pulling direction is applied to the fitting portion 48, the receiving portion 44 generates a force in the tightening direction, and there is almost no possibility that the fixing belt 46 is detached from the attachment belt 42. As in the conventional example, the fixing belt 46 is slidable along the longitudinal direction of the subject at the fitting portion, and can fix the subject at an arbitrary position in the body axis direction.
[0027]
A loop tape 50 and a hook tape 52 are respectively attached to the front and back of the front end of the fixing belt 46, and are bonded to the front end of the fixing belt attached to the other side of the top plate 32 as shown in FIG. The specimen is fixed. Note that the connection between the fixing belts 46 is not limited to the use of an adhesive tape, and other means may be used.
[0028]
The material of the attachment belt 42 and the fixing belt 46 is required to be flexible. However, in the case of a medical diagnostic apparatus using X-rays such as an X-ray diagnostic apparatus and an X-ray CT apparatus, a material with less X-ray absorption. For example, nylon is preferable. In this case, the receiving portion 44 and the fitting portion 44 are preferably molded from polyethylene or the like.
[0029]
The present invention is not limited to the embodiment described above, and can be implemented with various modifications. For example, when the attachment belt 42 is bonded to the top plate, the arrangement of the pile tape and the hook tape may be exchanged. That is, a hook tape may be provided on the top plate 32 side and a pile tape may be provided on the attachment tape side. Further, although a plurality of attachment belts (here, three) are provided on one side of the top plate, they may be provided over the entire length or partially as in the conventional example shown in FIGS. Although the above description relates to a case where the present invention is applied to a bed apparatus of an X-ray CT apparatus, the present invention is applicable to other medical diagnostic apparatuses such as an MRI apparatus, a nuclear medicine diagnostic apparatus, and is not limited to a diagnostic apparatus. In addition, the present invention can also be applied to a lithotripter and a therapeutic apparatus for a thermal treatment apparatus. Furthermore, the present invention is not limited to medical devices, and can be applied to any fixing device used when fixing a person, an animal, or the like to a chair, a pillar, or the like.
[0030]
【The invention's effect】
As described above, according to the present invention, it is possible to provide a subject fixing device that exhibits the following effects.
[0031]
(1) By providing an attachment member that is detachably attached to a side portion of the fixing base on which the subject is placed and a fixing belt that is detachably attached to the attachment member, the attachment member is also attached to the fixing base. When the attachment member is damaged, it can be replaced independently, and the waste of replacing the whole can be eliminated.
[0032]
(2) One end of the fixing belt has a hook-shaped fitting portion, the attachment member has a receiving portion to which the fitting portion is fitted, and the fixing belt is slidably attached to the attachment member. As a result, when a force for removing the fixing belt from the attachment belt is applied, the receiving portion generates a tightening force, so that a fitting portion that is difficult to come off is realized without increasing the size.
