Description

[Technical Field]

[0001] The present invention relates to a medical bag sling, and more particularly to a non-magnetic medical bag sling that can be used in places where a strong magnetic field is generated, such as an MRI room. [Background technology]

[0002] It is known that magnetic objects should not be brought into places where strong magnetic fields are generated, such as MRI (Magnetic Resonance Imaging) examination rooms. For this reason, Patent Documents 1 and 2 describe non-magnetic wheelchairs that can be brought into MRI examination rooms. Furthermore, as described in Non-Patent Document 1, non-magnetic stretchers, wheelchairs, and IV stands are available for sale. [Prior art documents] [Patent documents]

[0004] [Non-Patent Document 1] E-Medical Tokyo Co., Ltd., Non-magnetic equipment (stretchers, wheelchairs, IV stands), [Retrieved July 27, 2024], Internet: https: / / www.emedicaltokyo.co.jp / business / medicaldevice / nonmagnetic.html Summary of the Invention [Problem to be solved by the invention]

[0005] Some patients undergoing MRI scans carry medical bags such as urine bags, abdominal drainage bags, etc. When these patients enter and exit the MRI room, they must use the non-magnetic stretchers, wheelchairs, IV stands, etc. mentioned above.

[0006] At this time, medical bags are often hung from the support (pipes) that make up stretchers, wheelchairs, IV stands, etc. using a sling. The sling used in this case is commonly an S-shaped hook made of non-magnetic resin.

[0007] However, the supports that make up stretchers, wheelchairs, IV stands, etc. include vertical supports (vertical pipes) that extend vertically and horizontal supports (horizontal pipes) that extend horizontally, so S-hooks are not necessarily suitable for hanging medical bags. In particular, medical bags have a scale printed on the surface to measure the contents, but when hung on an S-hook, the medical bag tilts at an angle, making it difficult to read the scale accurately.

[0008] The object of the present invention is to provide a medical bag sling that can be used on both vertical and horizontal poles, and on poles of various sizes, and is optimal for use in locations where strong magnetic fields are generated. [Means for solving the problem]

[0009] In order to solve the above problem, one aspect of the present invention provides a medical bag sling made of a non-magnetic material for suspending a medical bag, characterized in that it comprises two clamping pieces that face each other and clamp a support pole, two male screws that connect the two clamping pieces, and two female screws into which the male screws are threaded.

[0010] The medical bag sling of the present invention is made of a non-magnetic material, so it can be used in places where strong magnetic fields are generated, such as MRI rooms. It can also be used on vertical and horizontal supports attached to IV stands, wheelchairs, stretchers, etc. Furthermore, because the support is clamped between two clamping pieces and fastened with two screws, it can be used on supports of any size that can reach the length of the male screw, making it highly versatile.

[0011] In the medical bag sling of the present invention, it is preferable that one of the clamping pieces is rotatable relative to one of the male threads and is capable of engaging with the other male thread by this rotation.

[0012] With this configuration, the medical bag hanger can be removed from the support by simply loosening the male screw and rotating one of the clamping pieces relative to the other male screw, without having to completely remove the male screw from the female screw, and can also be attached by performing the reverse operation. The engagement of one of the clamping pieces with the male screw can be achieved, for example, by providing an opening in one of the clamping pieces, and it is more preferable to provide this opening on the upper surface side of one of the clamping pieces.

[0013] Furthermore, the medical bag sling of the present invention is preferably provided with a hook for a vertical support pole and a hook for a horizontal support pole for suspending the medical bag. With this configuration, the medical bag can be easily attached to a vertical support pole such as an IV stand or a horizontal support pole such as a wheelchair or stretcher.

[0014] In addition, in this configuration, the hook for the horizontal support is configured to protrude by sliding the two clamping pieces, so that the hook for the horizontal support can protrude only when in use, and there is no risk of the hook getting caught when not in use.

DETAILED DESCRIPTION OF THE INVENTION

[0016] Hereinafter, a mode for carrying out the present invention will be described with reference to the embodiments and drawings, but the embodiments shown below are not intended to limit the present invention to those described herein, and the present invention is equally applicable to various modifications without departing from the technical idea set forth in the claims. Note that in each drawing used for explanation in this specification, each component is shown at a different scale so that each component can be recognized on the drawing, and is not necessarily shown in proportion to its actual size.

[0017] [Embodiment] The configuration of the main parts of a medical bag sling 100 according to an embodiment will be described using Figures 1 and 2. Figure 1A is a perspective view showing the medical bag sling 100 attached to a vertical support P1 such as an IV stand, Figure 1B is an exploded perspective view of A, and Figure 1C is a perspective view showing the medical bag sling 100 attached to a horizontal support P2 such as a stretcher or wheelchair. Figures 2A and 2B are images of a prototype.

[0018] The medical bag sling 100 is made of wood, which is a non-magnetic material, and as shown in FIG. 1, it comprises a first clamping piece 1, a second clamping piece 2, and two nuts 3.

[0019] More specifically, the first clamping piece 1 is made of a wooden main piece 11 and a wooden reinforcing piece 12. In this embodiment, the main piece 11, reinforcing piece 12, and second clamping piece 2 are all made of the same plywood (see FIG. 2) and are made of rod-shaped plates of the same width and thickness. Furthermore, plywood is less likely to deform than solid wood and has high strength, so the strength required for the medical bag sling device 100 can be ensured. The main piece 11 and the reinforcing piece 12 of the first clamping piece 1 are bonded to each other with an adhesive. Therefore, the thickness of the first clamping piece 1 is twice that of the second clamping piece 2.

[0020] A first vertical hook 13 for hanging the medical bag B is formed at one end of the main piece 11 so as to protrude beyond the end of the reinforcing piece 12. In other words, the length of the main piece 11 is longer than the reinforcing piece 12 by the length of the first vertical hook 13. The first vertical hook 13 has a hook shape that hooks a medical bag in the width direction of the main piece 11 (direction perpendicular to the thickness direction).

[0021] 1 and 2, the first clamping piece 1 is provided with a first wooden male screw 14 and a second wooden male screw 15 that extend in one direction in the thickness direction of the main piece 11. The first male screw 14 and the second male screw 15 have a threaded portion T and an unthreaded cylindrical portion S. As will be described later, the threaded portion T and the cylindrical portion S have different thicknesses, with the threaded portion T being thinner. The first male screw 14 and the second male screw 15 extend parallel to each other and pass through the reinforcing piece 12 and are fixed to the main piece 11 by fitting a fixing pin 16 in the main piece 11. Furthermore, the reinforcing piece 12 has vertical and horizontal recesses 17 formed at approximately the center of the first male screw 14 and the second male screw 15, which are shaped to abut against the vertical and horizontal supports.

[0022] The second clamping piece 2 is also made of wood, and as shown in Figures 1 and 2, a second vertical hook 21 for hanging the medical bag B is formed on one end of the second clamping piece 2, similar to the first vertical hook 13 on the main piece 11 of the first clamping piece 1. This second vertical hook 21 is also a hook-shaped hook that hooks in the width direction of the second clamping piece 2 (the direction perpendicular to the thickness direction).

[0023] Furthermore, unlike the main piece 11 of the first clamping piece 1, a horizontal hook 22 for hanging the medical bag B is formed on the other end of the second clamping piece 2. This horizontal hook 22 is made up of two wooden dowels that stand upright in the thickness direction. The second clamping piece 2 is also formed with an elongated hole 25 into which the first male screw 14 is fitted and an open elongated hole 26 into which the second male screw 15 is fitted.

[0024] The elongated holes 25 and the open elongated holes 26 are rectangular with rounded corners, and are sized to connect the vertical support center position V of the second male screw 15 when the vertical support P1 is clamped (see the enlarged view in Figure 1A) and the horizontal support center position H of the second male screw 15 when the horizontal support P2 is clamped (see the enlarged view in Figure 1C).

[0025] The elongated opening hole 26 has an opening 261 formed therein that is wide enough to allow the threaded portion T of the second male screw 15 to pass through but not the cylindrical portion S. As shown in Fig. 1A, this opening 261 opens to the upper surface of the second clamping piece 2 in accordance with the bending direction of the first vertical hook 13 and the second vertical hook 21. The opening 261 is formed around a position M that is the middle between the vertical column center position V and the horizontal column center position H. As shown in S1 of FIG. 3, if the width of the opening 261 is L, the diameter of the threaded portion T is D1, and the diameter of the cylindrical portion is D2, then D1 <L<D2となる。

[0026] In addition, the second clamping piece 2 is formed with a vertical recess 23 that abuts together with the vertical and horizontal recesses 17 provided in the reinforcing piece 12 of the first clamping piece 1 to clamp the vertical support P1, and a horizontal recess 24 that abuts together with the vertical and horizontal recesses 17 to clamp the horizontal support P2.

[0027] The nut 3 is also made of a non-magnetic material and is made of a wooden member. As shown in Figures 1 and 2, a female screw 31 into which the first male screw 14 and the second male screw 15 are threaded is cut in the center of the rectangular parallelepiped. The shape of the nut 3 is not limited to a rectangular parallelepiped as in this embodiment, and may be a cylindrical or polygonal prism shape.

[0028] The medical bag sling 100 configured as described above clamps a vertical support P1 or a horizontal support P2 between the first clamping piece 1 and the second clamping piece 2, and the clamping by the first clamping piece 1 and the second clamping piece 2 is achieved by a structure in which the first male screw 14 and the nut 3, and the second male screw 15 and the nut 3 are fastened together, as shown in Figures 1 and 2.

[0029] The vertical support P1 is specifically a support (pipe) extending vertically (vertically) in a wheelchair or an IV stand. The horizontal support P2 is specifically a support (pipe) extending horizontally (horizontally) in a stretcher or a wheelchair.

[0030] [Installation method] An example of a method for attaching the medical bag sling 100 to the vertical support P1 of an IV stand will be described with reference to FIGS. In the medical bag sling 100, a user such as a nurse passes the first male screw 14 of the first clamping piece 1 through the elongated hole 25 side of the second clamping piece 2, but leaves the second male screw 15 of the first clamping piece 1 unpassed through the elongated hole 26 side of the second clamping piece 2. Then, the nut 3 is threaded into the first male screw 14 side to a position corresponding to the diameter of the vertical support P1, and the nut 3 is threaded slightly into the second male screw 15 side; this state is considered to be the ready state. In this ready state, the second clamping piece 2 can rotate around the first male screw 14 as the rotation axis, and this rotation allows it to engage with the second male screw 15 via the elongated hole 26.

[0031] FIG. 3 is a schematic diagram showing steps S1 to S4 of the procedure for attaching the medical bag sling device 100 from this preparation state. While the user abuts the vertical and horizontal recesses 17 of the first clamping piece 1 of the prepared medical bag sling device 100 against the vertical support P1, as shown in S1 of Figure 3, the user slides the second clamping piece 2 and tilts the elongated opening hole 26 side downward (widthwise) to pass the threaded portion T of the second male screw 15 through the opening 261. At this time, because the diameter D2 of the cylindrical portion S is wider than the width L of the opening 261, the opening 261 cannot be passed through at the cylindrical portion S, so the threaded portion T passes through the opening 261.

[0032] Furthermore, in this embodiment, the opening 261 of the elongated opening hole 26 is provided on the upper surface of the second clamping piece 2. Therefore, the rotation of the second clamping piece 2 relative to the first male screw 14 is counterclockwise, as shown in S1. If a medical bag B were already hanging from the second vertical hook 21, the weight of the medical bag B could cause the second clamping piece 2 to rotate relative to the first male screw 14. However, in this embodiment, because the rotation of the second clamping piece 2 is counterclockwise, the second clamping piece 2 comes into contact with the second male screw 15 and stops rotating, preventing the medical bag B from falling off the second vertical hook 21.

[0033] Next, as shown in S2 of FIG. 3, the user inserts the threaded portion T of the second male screw 15 into the elongated opening hole 26, and then aligns the second clamping piece 2 and the first clamping piece 1 so that they are horizontal. Then, as shown in the cross-sectional view of S2 in FIG. 3, the second clamping piece 2 is moved closer to the first clamping piece 1 so that the cylindrical portion S enters the elongated opening hole .

[0034] Next, as shown in S3, the user slides the second clamping piece 2 so that the position of the second male screw 15 in the opening elongated hole 26 moves from the central position M to the vertical support center position V, and then screws in the nut 3 so that the vertical recess 23 abuts against the vertical support P1 (S4).

[0035] When the medical bag sling 100 is attached to the vertical support P1 in this way, the first vertical hook 13 and the second vertical hook 21 are aligned and spaced apart by the thickness of the reinforcing piece 12 and the diameter of the vertical support P1, as shown in Fig. 1A. Then, a medical bag B is hung from the first vertical hook 13 and the second vertical hook 21 (see Fig. 4A). Note that the medical bag B in Fig. 4A is not a real medical bag (such as a urine bag or a drainage bag) but a fake bag.

[0036] At this time, the first vertical hook 13 and the second vertical hook 21 are spaced apart according to the diameter of the vertical support P1, so the medical bag B can be hung stably without tilting as would occur if the medical bag B were hung using a so-called S-shaped hook. Therefore, the scale printed on the surface of the medical bag can be read accurately.

[0037] In addition, in this embodiment, as shown in FIG. 1A, when the medical bag sling 100 is attached to the vertical support P1, the horizontal hooks 22 do not protrude, making it less likely for the patient's clothing to get caught, thereby ensuring safety.

[0038] The procedure for removing the medical bag sling 100 from the vertical support P1 is to reverse the attachment procedure from steps S4 to S1. Furthermore, in the medical bag sling 100 of this embodiment, the elongated opening 26 is provided with an opening 261 through which the second male screw 15 passes, so the second clamping piece 2 can be rotated around the first male screw 14 as a rotation axis, and the medical bag sling 100 can be removed from the vertical support P1 simply by loosening the nuts 3 of the first male screw 14 and the second male screw 15 without having to completely remove them. Furthermore, when attaching the medical bag sling 100 next time, it can be attached to the support with the two nuts 3 still attached. In this way, attachment and detachment can be performed easily and quickly.

[0039] The medical bag sling 100 can be attached to a horizontal support P2 by simply rotating the orientation of the medical bag sling 100 by 90 degrees in the same way as for a vertical support P1, as shown in Figure 1C. In the case of a horizontal support P2, the second clamping piece 2 is slid so that the position of the second male screw 15 in the elongated opening hole 26 is at the center position H of the horizontal support. This sliding action causes the horizontal hook 22 to protrude, allowing the medical bag B to be hung. At this time, the horizontal hook 22, which is made up of two dowels, allows the medical bag B to be hung stably.

[0040] As described above, the medical bag sling 100 of this embodiment is made entirely of non-magnetic wood, so that the medical bag B can be suspend- ed even in places where a strong magnetic field is generated, such as an MRI room.

[0041] Furthermore, the medical bag sling 100 is configured to clamp a vertical support P1 or a horizontal support P2 between the first clamping piece 1 and the second clamping piece 2, and can therefore be used to suspend medical bags from stretchers, wheelchairs, IV stands, and the like that are used in places where strong magnetic fields are generated.

[0042] Furthermore, medical bag sling 100 is structured so that the clamping between first clamping piece 1 and second clamping piece 2 is tightened by a first male screw 14 and a nut 3 having a female screw 31 into which this first male screw 14 screws, and by a second male screw 15 and a nut 3 having a female screw 31 into which this second male screw 15 screws. Therefore, medical bag sling 100 is highly versatile and can be used with vertical struts P1 or horizontal struts P2 of various dimensions.

[0043] [Variations] In this embodiment, the first male screw 14 and the second male screw 15 are attached to the first clamping piece 1, and the female screw 31 is cut into the nut 3, but the present invention is not limited to this. For example, as shown in Fig. 4B, a medical bag sling device 100A may be configured such that the first male screw 32 and the second male screw 33 are attached to a rectangular parallelepiped 3A, and the female screw 18 is cut into the main piece 11A of the first clamping piece 1A.

[0044] In this embodiment, the main piece 11 and reinforcing piece 12 of the first clamping piece 1, and the second clamping piece 2 are all made from the same plywood, but they may also be made from different plywood pieces of different thicknesses. In this case, the first clamping piece 1 may be made of only the main piece 11, without using the reinforcing piece 12. Furthermore, the medical bag sling 100 made of a non-magnetic material does not necessarily have to be made of wood; it can be made of a non-magnetic resin, a combination of wood and resin, or a non-magnetic metal. The second clamping piece may be reinforced with a reinforcing piece. Also, the hooks are separate for vertical and horizontal use, but a single hook shape may be used for both vertical and horizontal use. [Explanation of symbols]
