In addition, the medical hanger which concerns on each embodiment of this invention can also be utilized in animal medicine.

  First, the support arm of the medical hanger according to the embodiment of the present invention and the peripheral configuration of the support arm will be described. FIG. 1 is a perspective view showing a medical hanger body according to an embodiment of the present invention. In FIG. 1, 10 is a medical hanger body, 11 and 12 are support arms, 12a is a latch hole, 12b is a drop prevention part, 13 is a support arm, 13a is a latch hole, 13b is a fall prevention part, 14 is Support arm, 14a is a retaining hole, 14b is a fall prevention part, 15 and 16 are support arms, 16a is a catch hole, 16b is a fall prevention part, 17 is a support arm, 17a is a catch hole, 17b is a fall prevention part , 18 is a support arm, 18a is a retaining hole, 18b is a drop-off prevention part, 19 is a cylindrical body, 19a is a hollow part, and 20 is a case. FIG. 2 is a perspective view showing a state in which the support arm of the medical hanger main body according to the embodiment of the present invention is closed. The reference numerals used in FIG. 2 are the same as those in FIG. Moreover, FIG. 3 shows the medical hanger main-body part which concerns on embodiment of this invention, (a) is a top view, (b) is a bottom view. In FIG. 3, 21a, 21b, 21c, 21d, 21e, 21f, 21g and 21h are openings, and other reference numerals are the same as those in FIG.

  As shown in FIGS. 1 and 3, the medical hanger body 10 according to the embodiment of the present invention includes eight support arms 11, 12, 13, 14, 15, 16, 17 and 18 that support the case 20. It is provided at equal intervals so as to extend radially from the center. Further, as will be described later, these are sterilized so that they can be used in the operating room. Each support arm is formed in the same shape and size by press working of stainless steel or the like, and up to three infusion bags are suspended on one support arm by hanging the infusion bag latching portion. be able to. Further, as shown in FIG. 2, the support arms 11, 12, 13, 14, 15, 16, 17, and 18 rotate so that the rotation axis is horizontal, that is, the tip side rotates so as to move up and down. It is provided to do. Therefore, when sterilizing the medical hanger body 10, the support arms 11, 12, 13, 14, 15, 16, 17 and 18 can be accommodated in the autoclave so that the umbrella is folded. . Further, when storing the medical hanger body 10, the support arms 11, 12, 13, 14, 15, 16, 17 and 18 can be folded and placed in the container.

  In addition, the eight support arms can be provided so as to be unevenly distributed in a predetermined direction with the case 20 as a base point, not at equal intervals, and even if it is unevenly distributed in this way, the present invention can solve the problem. Although possible, it is conceivable that the medical hanger body 10 is tilted and rotation is hindered by a frictional force between a cylindrical body and a hanging part described later. Furthermore, it is desirable to make it equidistant also from a viewpoint of ensuring the space | interval of adjacent infusion bags. In addition, in the medical hanger body 10 according to this embodiment, eight support arms are provided. However, if two or more support arms are provided, six or more infusion bags can be suspended. Any number is acceptable. However, for example, when the number is 16 or more, it is necessary to make the length twice or more than the support arm shown in FIG. Such a length makes it impossible to accommodate in a small autoclave. Therefore, it is not preferable that the number of support arms is 16 or more, and it is desirable that the number is 12 or less. When two support arms are provided, the space in the direction orthogonal to the two support arms is not utilized at all for hanging the infusion bag, so it is desirable to provide four or more support arms. These support arms can also be formed by methods other than stainless steel pressing, for example, by appropriately processing aluminum alloy pipes or rods. This method is preferable. Moreover, you may mix the support arm of a different use and shape, such as a support arm for hooking an endoscope.

  Further, as can be seen from the support arms 12, 13, 14, 16, 17 and 18 in FIG. 1, drop-out preventing portions 12b, 13b, 14b, 16b, 17b and 18b projecting upward are formed at these tip portions. Has been. In FIG. 1, the drop-out preventing portions of the support arms 11 and 15 are not shown, but the drop-out preventing portions having the same shape and size are formed in the support arms 11 and 15. These drop-off prevention parts have a role of preventing an infusion bag or the like from dropping from the support arm during a surgical operation or a surgical procedure, thereby hindering medical practice. Further, as can be seen from the support arms 12, 13, 14, 16, 17 and 18 in FIG. 1, latching holes 12a, 13a, 14a, 16a, 17a and 18a are formed on the base end sides thereof. . In FIG. 1, the latching holes of the support arms 11 and 15 are not shown, but the latching holes of the same shape and size are also formed in the support arms 11 and 15. These hooking holes are used to hang a fourth infusion bag or a suction tube, for example, by hanging an S-shaped hook. At the same time, the weight of the medical hanger body 10 can be reduced. Also contribute.

  As will be described later, the case 20 houses bearings that support the rotation of the support arms 11, 12, 13, 14, 15, 16, 17, and 18, and the support arms 11, 12, 13, 14, Slits are formed so that 15, 16, 17 and 18 can rotate. Further, as shown in FIG. 3B, openings 21a, 21b, 21c, 21d, 21e, 21f, 21g, and 21h are formed on the lower surface side of the case 20. The openings 21a, 21b, 21c, 21d, 21e, 21f, 21g and 21h are arranged to correspond to the positions of the base ends of the support arms 11, 12, 13, 14, 15, 16, 17 and 18, respectively. The base end portions of these support arms and the bearings in the case 20 can be easily cleaned. A cylindrical body 19 is provided at the center of the case 20 so as to penetrate in the vertical direction. The cylindrical body 19 is held in a state where a hanging portion of a support column described later is inserted through the hollow portion 19a. Further, since the inner diameter of the cylindrical body 19 is formed to be larger than the diameter of the hanging part of the support column, the cylindrical body 19 can rotate in the direction so that the rotation axis is horizontal.

  Further, the detailed shape of the support arm and the rotation support structure will be described. FIG. 4 is a cross-sectional view showing a configuration for supporting the rotation of the support arm. In FIG. 4, 11a is a retaining hole. 11b is a drop-off prevention part, 11c is a latching area | region, 11d is a bearing opening part, and other code | symbol shows the same thing as FIG. FIG. 5 is a cross-sectional view illustrating a detailed configuration of the support arm, the bearing, and the case. In FIG. 5, 22 is an annular bearing, 23a is a slit, 23aa is an upper edge portion, 23ab is a lower edge portion, 24 is a lower end portion, 25 is a step portion, and other reference numerals are the same as those in FIG. 4 and 5 show only the support arm 11, the shape of the details of the support arms 12, 13, 14, 15, 16, 17 and 18 and the rotation support structure are all formed to be the same. ing.

  As shown in FIG. 4, the support arm 11 is formed into a substantially elongated strip shape as a whole, and the tip portion is formed as a drop-off prevention portion 11 b that protrudes while curving upward. In addition, the ridgeline at the upper end is formed in a concave shape within a range of about two-thirds of the total length from the drop-off prevention portion 11b. This portion is a hooking region 11c for hooking and supporting an infusion bag or the like. That is, by forming the concave hooking region 11c, when the medical hanger body 10 is moved, the infusion bag or the like moves to the cylindrical body 19 side, making it difficult for doctors and nurses to reach it. Is preventing. Further, the support arm 11 has a slight downward slope toward the distal end side, and the hooking region 11c also has a slight downward slope toward the distal end side. This downward slope of the latching region 11c also acts to prevent the infusion bag or the like from moving to the cylindrical body 19 side. Note that the entire support arm 11 may not be inclined downward toward the distal end side, but only the latching region 11c may be downwardly inclined. A latching hole 11a is provided on the base end side with respect to the concave latching region 11c. As described above, the hooking hole 11a is configured to hang, for example, the fourth infusion bag or the suction tube by hooking the S-shaped hook. The distance from the stop hole 11a is set in consideration of this.

  Further, as shown in FIG. 5, a bearing opening 11 d is formed at the base end of the support arm 11. An annular bearing 22 is inserted through the bearing opening 11 d, and the support arm 11 rotates around the annular bearing 22. Although not shown in FIG. 5, the annular bearing 22 is inserted into the bearing openings of the support arms 12, 13, 14, 15, 16, 17 and 18, and all the support arms are supported by the annular bearing 22. The rotating shaft is rotatably supported so that the rotating shaft is horizontal. The annular bearing 22 is housed inside the case 20, but is not fixed to the case 20. If the annular bearing 22 is fixed to the case 20, a region where the brush and the swab do not enter when cleaning the base end portion of the support arm and the bearing is not preferable in terms of hygiene management. Therefore, cleaning is facilitated by causing the annular bearing 22 to move slightly within the case 20.

  In order to facilitate alignment, the case 20 is fixed at a position where the lower end portion 24 contacts the step portion 25 of the cylindrical body 19. Further, as described above, the case 20 has the slits 23 a formed at positions corresponding to the support arms 11. The slit 23a is formed by press working, and enables the support arm 11 to rotate and has a role of setting a rotation angle. That is, when the tip end portion of the support arm 11 is rotated upward, the rotation is restricted when the vicinity of the base end portion of the support arm 11 comes into contact with the upper edge portion 23aa of the slit 23a. When the tip of the support arm 11 is rotated downward, the rotation is restricted when the vicinity of the base end of the support arm 11 comes into contact with the lower edge 23ab of the slit 23a. With this configuration, there is no need to provide a complicated structure for restricting rotation of the bearing, and the positions of the upper edge portion 23aa and the lower edge portion 23ab of the slit 23a can be appropriately set in the press work. is there.

  Further, the stopper will be described. FIG. 6 is a perspective view showing the stopper. In FIG. 6, 26 is a stopper, 27 is a hook portion, 28 is a restricting portion, and 29 is a screw portion. The stopper 26 is mainly intended to prevent the medical hanger body 10 from dropping from the hanging part of the column. The stopper 26 serves the main purpose, a restriction portion 28, a screw portion 29 provided so as to protrude from the upper surface of the restriction portion 28, and a hook provided so as to hang down from the lower surface of the restriction portion 28. Part 27. Moreover, it is formed in a size that can be accommodated in a small autoclave.

  The restricting portion 28 is formed to have a diameter larger than the inner diameter of the cylindrical body 19 so that the medical hanger main body portion 10 does not fall through the hollow portion 19 a of the cylindrical body 19. As described above, the inner diameter of the cylindrical body 19 is formed so as to be larger than the diameter of the hanging portion of the support column, and the cylindrical body 19 can be rotated in the direction so that the rotation axis is horizontal. It is the restricting portion 28 that supports the medical hanger body 10 while being in contact with the body 19. The screw portion 29 is screwed into a screw hole provided in the hanging portion of the support column. Therefore, there is an advantage that mounting of the stopper 26 can be simplified compared to a configuration in which a separate screw is prepared and the stopper 26 is screwed. The hook portion 27 is used, for example, for hanging an endoscope in an operation, hanging a patient's arm after the operation, or hanging an animal's hind limb. Furthermore, it can also be used for a doctor to hold the hook part 27 and rotate the medical hanger body part 10 or to move the hanging part of the column during the operation. The hook portion 27 may be omitted, or a grip handle may be provided in place of the hook portion 27.

  Next, the support will be described. FIG. 7 is a perspective view showing the support column. In FIG. 7, 30 is a support | pillar, 31 is a base | substrate part, 32 is a horizontal part, 33 is a hanging part, 33a is a screw hole. FIGS. 8A and 8B are perspective views showing a method of using the support column, wherein FIG. 8A shows a state where a sterile cloth cylinder is being covered, and FIG. 8B shows a state where the sterile cloth cylinder has been covered. In FIG. 8, 34 is a sterilized cloth cylinder, and other reference numerals are the same as those in FIG.

  As shown in a hanging portion 33 in FIG. 7, the main feature of the column 30 is that the tip portion and the vicinity thereof are suspended. When the entire body is upright or almost upright like a general support, when the medical hanger body 10 is mounted on the tip and its vicinity, it is behind the tip and its vicinity. The infusion bag or the like is hidden, and the visibility of the infusion bag or the like is deteriorated. When the tip portion and the vicinity thereof are suspended like the hanging portion 33, the infusion bag or the like is not hidden behind the tip portion and the vicinity thereof, and the visibility of the infusion bag or the like is improved. Furthermore, the replacement work of the infusion bag is facilitated. As described above, the medical hanger body 10 is attached by inserting the hanging portion 33 into the cylindrical body 19 of the medical hanger body 10, and further inserting the screw hole 33 a of the hanging portion 33 into the stopper 26 and the screw portion 29. By screwing in. The horizontal portion 32 is formed, for example, so that an S-shaped hook or the like can be hooked, and a suction tube or the like can be hooked on the S-shaped hook. In order to prevent the S-shaped hook from sliding down from the horizontal portion 32, a slip-down preventing projection that protrudes upward from both ends of the horizontal portion 32 or a portion near one end may be provided. Further, depending on the use of the medical hanger, it may be formed in an inverted U shape or the like without being formed horizontally.

  The base part 31 is a basic part for holding the medical hanger body part 10, the stopper 26, and the like at a predetermined height. In FIG. 7, the lower portion of the base portion 31 is omitted, but this lower portion may be fixed to a leg portion with a caster, and a medical device is mounted and moved or supported as will be described later. You may fix to a medical device support unit. Further, the base portion 31 may be formed so as to extend upward from the end portion of the horizontal portion 32 and fixed to the ceiling of the operating room or the like. Further, the horizontal portion 32 may be formed so as to extend horizontally to the wall surface of the operating room as it is, and may be fixed on the wall surface. In such a case, you may comprise a horizontal part so that expansion-contraction is possible. In addition, it may be fixed to a casing of a predetermined medical device such as a dialysis device. In any case, as long as the tip 30 and the vicinity thereof hang down, the support 30 can be configured in various configurations other than that shown in FIG. The use of the medical device can be assisted by a medical hanger, and the convenience of the medical device can be enhanced.

  By the way, the support | pillar 30 cannot be accommodated in an autoclave from the magnitude | size. Therefore, when used in an operating room, it is used after being covered with a sterile cloth cylinder. That is, as shown in FIG. 8A, the hanging portion 33 is inserted into a sterilized cloth cylinder 34 that has been sterilized in advance, and further inserted from the horizontal portion 32 to the base portion 31. And as shown in FIG.8 (b), the whole support | pillar 30 is covered with the sterilization cloth cylinder 34. As shown in FIG.

In addition, a clamp 48a is provided around the lower opening of the support hole 49, and the clamp 48a can be tightened by a knob 48b. In such a medical instrument support unit 40, the base portion 31 of the support column 30 is inserted into the support hole 49 and tightened with the clamp 48a. For example, the suction device is placed on the tray on the leg member 41, and the suction tube is set to any one of them. Use while properly hanging on the support arm, or place the laser transmitter on the arm fixed to the upper support member 44 and use the laser knife cable (light guide) while hanging on any one of the support arms. Can be used in various ways. Moreover, since the support | pillar 46 can be expanded-contracted, the raising / lowering of the medical hanger main-body part 10 is also attained.

  The present invention is not limited to the description of each embodiment described above. For example, the hanging part may have two upper and lower parts, and a medical hanger body may be attached to each. . In other words, it is possible to use the upper and lower two-stage medical hanger body portions in a rotatable state by providing the lower hanging portion with the function of the stopper restricting portion. In addition, a part or all of the support arm can be attached or detached. For example, at the base end portion of the support arm 11, instead of forming the four bearing openings 11 d, a protruding portion that protrudes in a cylindrical shape on the left and right is provided. Inside, a substantially U-shaped bearing for receiving these protrusions is provided, and a wide portion through which these protrusions can be inserted is formed in the upper part of the substantially U-shaped bearing in the slit of the case. If so, the protrusion of the support arm 11 may be inserted or removed by inserting the wide portion of the slit into the bearing. Furthermore, a screw is provided at the upper end portion of the hanging portion 33 of the support column 30 and a screw hole is formed at the lower end portion of the horizontal portion 32 so that the hanging portion 33 can be attached to and detached from the horizontal portion 32. 10 may be removed while remaining integral with the hanging portion 33 so that sterilization can be performed. Thus, various modifications can be made without departing from the scope described in each claim.
