  By the way, a tube connected to a blood bag or the like is stored in a folded state before use (at a stage where it is wrapped in a packaging material). )). If a tube with such folds is inserted into the tube seal part of multiple tube seal devices, the tube will float relative to the normal seal position (hereinafter this phenomenon is also referred to as “tube float”). Yes.) When the tube floats, for example, the insertion of the tube may not be detected and the sealing operation may not be performed, or the seal may not be welded at a desired position. If the seal cannot be welded at a desired position, a sealing failure may occur, such as the tube breaking or insufficient sealing at a part of the tube.

  Note that the tube cannot be lifted by applying tension (tensile force) along the tube longitudinal direction to the tube with creases or the like. However, according to experiments conducted by the present inventor, if the tube along the tube longitudinal direction is applied to a tube with creases or the like, the tube does not always get lifted cleanly. In some cases, it was not improved as expected.

  Therefore, the present invention has been made to solve such a problem, and even a tube with a crease or the like can be smoothly welded to a seal, and the occurrence of poor sealing can be suppressed. An object of the present invention is to provide a medical tube seal device set and a mounting table.

If a fold or the like is located near the left and right ends of the mounting table, that is, closer to the hand holding the tube, the tube can be lifted by applying a slight tension to the tube, while it is near the center of the mounting table. When a fold or the like is located, the distance from the hand to the position of the fold or the like is far away, so even if tension is applied to the tube with the hand, the force is not easily transmitted to the position of the fold or the like, and the tube floats. Is difficult to fix.

  Based on the above knowledge, the inventor of the present invention has intensively studied to find a means for improving the floating of the tube even if it is a tube in which a fold or the like is located near the center of the mounting table. As a result, if the mounting surface of the mounting table is configured as described below, the tube floating can be improved even if it is a tube where a fold or the like is located near the center of the mounting table.

Next, the configuration of the mounting table 60 will be described with reference to FIGS. 5 and 6.
FIG. 5 is an external perspective view of the mounting table 60 according to the first embodiment. FIG. 6 is a front view of the mounting table 60 according to the first embodiment. FIG. 7 is a diagram (a front view of the mounting table 60) shown for explaining the height of the mounting surface 70 in the mounting table 60. In FIG. 7, the illustration of the device connection portion 80 is omitted to facilitate understanding of the invention.

  As shown in FIGS. 5 to 7, the mounting table 60 includes a mounting surface 70 formed in a staircase shape that rises in three steps from the left and right end portions to the central portion of the mounting table 60, and the mounting surface 70. The apparatus connection part 80 stood up back is provided, and the handles 90 and 91 provided in the right-and-left both ends of the mounting surface 70 are provided.

  The placement surface 70 is formed so that seven planes are stepped in total, and is symmetrical with respect to the center as a boundary. As shown in FIG. 7, the height of the mounting surface 70 at the position where the tube seal device 10A is mounted (in the vertical direction from the desk surface to the mounting surface when the mounting table 60 is placed on a desk, for example, Of the placement surface 70 where the tube seal devices 10A to 10H are respectively placed, such that the distance along the surface H1 is H1, and the height of the placement surface 70 at the position where the tube seal device 10B is placed is H2. When the height is H1 to H8, the height of the mounting surface 70 satisfies “H1 = H8, H2 = H7, H3 = H6, H4 = H5”, and “H1 <H2 <H3 <H4” and It is set to satisfy “H5> H6> H7> H8”. Moreover, although mentioned later for details, the height of the mounting surface 70 is a virtual curve VC (which will be described later) that protrudes in the vertical upward direction when the positions of each pair of electrodes in the tube seal devices 10A to 10H are connected. (See FIG. 9A).

  The device connection portion 80 includes eight power connectors 82A to 82H, eight communication connectors 84A to 84H, 16 (2 × 8 sets) positioning pins 86A to 86H, 87A to 87H, and eight Device fixing screws 88A to 88H are provided. These parts correspond to a power terminal, a communication terminal, a positioning hole, and a device fixing screw hole provided on the back surface of the tube seal devices 10A to 10H, and the eight tube seal devices 10A to 10H are placed on the mounting surface. It is comprised so that it may be arrange | positioned along with the left-right direction on 70.

  Next, as compared with the configuration of the medical tube seal device set 8 according to the comparative example, the mounting table 60 (the height of the mounting surface 70) of the medical tube seal device set 1 according to the first embodiment is described in more detail. explain.

FIG. 8 is a view for explaining a medical tube seal device set 8 according to a comparative example. In FIG. 8, the position of the electrode and detection part in tube seal part 20A-20H when the medical tube seal apparatus set 8 is seen from the front is shown typically.
FIG. 9 is a view for explaining the medical tube seal device set 1 according to the first embodiment. Fig.9 (a) is a front view which shows typically the position of each electrode and detection part of tube seal part 20A-20H in tube seal apparatus 10A-10H, FIG.9 (b) is tube seal part 20A-20H ( It is a figure which shows an example which inserted the tube T in the slit part of each cover member.
In FIG. 8, FIG. 9 (a) and FIG. 9 (b), the electrodes and detectors that are not originally visible from the front and the inserted tubes are shown by solid lines in order to facilitate understanding of the invention. Yes.

  The medical tube seal device set 8 according to the comparative example has basically the same configuration as the medical tube seal device set 1 according to the first embodiment, but as shown in FIG. The placement surface 870 is different from the medical tube seal device set 1 according to the first embodiment in that the placement surface 870 is not formed in a step shape but is formed of one plane.

  When the tube T with a crease or the like is inserted into the tube seal portions 20A to 20H of the medical tube seal device set 8 according to the comparative example, the tube may float (for example, as shown in FIG. 8). (Refer to the position of the tube seal portion 20D.) As a result, there may be cases where the insertion of the tube T is not detected and the sealing operation is not performed or the seal cannot be welded at a desired position.

  In addition, as shown in FIG. 8, when a folding crease or the like is located near the center of the mounting table 860, the distance from the hand (both ends in the left and right direction of the mounting table 860) to the position of the folding crease is far away, Even if tension is applied to the tube T, the force is not easily transmitted to a position such as a crease, and the tube is difficult to lift.

  On the other hand, in the medical tube seal device set 1 according to the first embodiment, as described above, the height of the mounting surface 70 of the mounting table 60 is “H1 = H8, H2 = H7, H3 = H6, H4. = H5 ", and" H1 <H2 <H3 <H4 "and" H5> H6> H7> H8 "are set (see FIG. 7). Since all of the eight tube seal devices 10A to 10H have the same height from the bottom surface of each tube seal device to the pair of electrodes, the eight tube seal devices 10A to 10H are mounted on the mounting surface 70. When placed, the tube seal device disposed closer to the center in the left-right direction among the tube seal devices 10A to 10H has a position of the pair of electrodes (and the slit portion of the cover member) as compared to other tube seal devices. It can be said that it will be higher.

  The positional relationship between the electrodes 21A to 21H will be described in detail. As shown in FIG. 9A, the electrode 21A of the tube seal portion 20A and the electrode 21H of the tube seal portion 20H are the same as the entire electrodes 21A to 21H. Located at the lowest height. The next highest positions are the electrode 21B of the tube seal portion 20B and the electrode 21G of the tube seal portion 20G. The next highest positions are the electrode 21C of the tube seal portion 20C and the electrode 21F of the tube seal portion 20F. And the electrode 21D of the tube seal part 20D and the electrode 21E of the tube seal part 20E are in the highest position among the whole electrodes 21A-21H. When the positions of these electrodes 21A to 21H are connected, an imaginary curve VC that is bent so as to be convex upward is drawn. Since the electrodes 22A to 22H are positioned to face the electrodes 21A to 21H, the description by illustration is omitted, but the positions of the electrodes 22A to 22H are similarly convex upward in the vertical direction. A curved virtual curve VC is drawn.

  As described above, when the positions of the pair of electrodes in the tube seal devices 10A to 10H are connected, the reason why the virtual curve VC that is convex upward is drawn as described above. This is because the height is set as such.

  In addition, although description by illustration is abbreviate | omitted, if the shape of the slit part provided in the cover member is the same in each of tube sealing apparatus 10A-10H, about the positional relationship of the lowest part of a slit part, Similarly to the pair of electrodes described above, when the positions of the lowermost portions (one of the two lowermost portions in each cover member) of the slit portions in the tube seal devices 10A to 10H are connected, they are vertically upward. A virtual curve VC that is convex toward the front is drawn.

  According to the medical tube seal device set 1 according to the first embodiment configured as described above, since the height of the mounting surface 70 in the mounting table 60 is set as described above, the tube seal device 10A. When the tube T is inserted into the tube seal portions 20A to 20H (slit portions of the cover members) of 10H to 10H (for example, the tube seal portions 20D and 20E) of the tube seal device located near the center in the left-right direction. ), The tube T comes into contact with the slit portion (the lowermost portion of the slit portion), and a pressing force acts on the tube T. As a result, when the tube T with a fold or the like is inserted, even if the fold or the like is positioned near the center of the mounting table 60, the floating of the tube T is improved by the pressing force acting on the tube T. (See FIG. 9B). As a result, it is possible to suppress the occurrence of an undesirable case where the insertion of the tube is not detected and the sealing operation is not performed or the seal cannot be welded at a desired position.

  Therefore, even if the medical tube seal device set 1 according to the first embodiment is a tube with creases or the like, the medical tube seal device 1 can smoothly seal and weld, and can suppress the occurrence of a seal failure. Tube seal device set.

  In the medical tube seal device set 1 according to the first embodiment, the placement surface 70 is formed in a step shape from the left and right end portions to the center portion of the placement table 60, so that the tube is placed on the placement surface 70. It becomes possible to place the sealing devices 10A to 10H stably.

  In the medical tube seal device set 1 according to the first embodiment, the height of the mounting surface 70 is convex upward in the vertical direction when the positions of each pair of electrodes in the tube seal devices 10A to 10H are connected.
