Description

  The present invention relates to a nutrient bottle pedestal for holding a nutrient bottle in which a liquid nutrient or the like is stored.

  Liquids such as nutrients, liquid foods, or drugs (generally referred to as “enteral nutrition”) for patients who have difficulty in feeding food from the oral cavity to the stomach due to trauma of the esophagus or oral cavity, disease, or surgery. In the following, enteral nutrition therapy is known as a method for administering "liquid". In enteral nutrition therapy, a liquid substance is fed into a patient's body through a flexible catheter (generally called “enteral nutrition catheter”).

  As a container for temporarily storing a liquid material, a nutrient bottle (hereinafter simply referred to as “bottle”) 80 made of a hard material (for example, a resin material) as shown in FIG. 8 is used. The bottle 80 has a substantially cylindrical shape with a bottom, and includes a container main body 81 that stores a liquid material, a lid 85 that closes an upper opening of the container main body 81, and a handle 87 for suspending the bottle 80. The side wall 82 of the container main body 81 is a substantially cylindrical surface. A port 84 through which the liquid material flows out is provided at the bottom 83 of the container body 81. The port 84 and an enteral feeding catheter inserted into the patient are connected by a flexible tube (not shown). The container main body 81 has transparency or translucency (or translucency) so that the amount of the liquid material therein can be visually recognized from the outside.

  The bottle 80 in which the liquid material is injected into the container main body 81 and the tube is connected to the port 84 is placed on the gantry with the bottom 83 facing down. FIG. 9 is a perspective view of an example of a conventional nutrition bottle gantry (hereinafter simply referred to as a “gantry”) 100. A plurality of ribs 108 that are in contact with the bottom 83 of the bottle 80 are erected in the annular holding portion 102. From the holding portion 102, three legs 105 protrude downward.

  FIG. 10 is a perspective view showing a state where the bottle 80 is placed on the gantry 100. The tube 90 connected to the port 84 of the bottle 80 is led out between the legs 105 of the gantry 100.

Japanese Patent No. 3834725

  In the conventional gantry 100, the tube 90 connected to the bottle 80 is not fixed. Therefore, when an unintended external force is applied to the tube 90, the external force is transmitted to the bottle 80 via the tube 90 and the bottle 100 is placed on the gantry 100. There is a problem that the posture stability of the bottle 80 is lacking, such as the inclination of the 80.

  Patent Document 1 describes a catheter attachment fixing device for locking a catheter to an S-shaped clip so that tension applied to a liquid supply tube is not transmitted to the catheter. However, this fixing device prevents the tension applied to the tube from being transmitted to the catheter, and does not prevent it from being transmitted to the bottle.

  On the other hand, in many cases, the bottle 80 is removed from the gantry 100 in order to inject a liquid material into the bottle 80 or to clean the used bottle 80. Therefore, when the holding mechanism of the tube 90 is provided on the gantry, it is desired that the tube 90 can be easily held and released.

  An object of the present invention is to solve the above-described problems of the conventional gantry and to provide a nutrition bottle gantry in which the posture of the bottle connected to the tube is not easily changed when an external force is applied to the tube. And

  The nutrition bottle gantry according to the present invention is a nutrition bottle gantry that holds a nutrition bottle provided with a cylindrical container body having a side wall and a bottom part, with the bottom part facing downward, and the side wall of the container body and A holding part for holding the bottom part is provided. The holding portion is formed with a slit extending downward from the upper end thereof. At the lower end of the slit, a tube gripping part for gripping a flexible tube connected to a port provided at the bottom of the container body is formed. The tube gripping portion has a pair of gripping surfaces facing each other. Locking projections that protrude toward the slits are formed above the pair of gripping surfaces so that the width of the slit is narrower than the distance between the pair of gripping surfaces. A pair of convex curved surfaces projecting toward each other are formed adjacent to the pair of gripping surfaces.

  Since the nutrition bottle pedestal of the present invention includes a tube gripping part for grasping the tube, even if an unintended external force is applied to the tube, the posture of the nutrition bottle held on the pedestal hardly changes.

  Since the locking projection is formed above the pair of gripping surfaces constituting the tube gripping portion, the possibility that the tube gripped by the tube gripping portion will unintentionally escape from the tube gripping portion can be reduced.

  Since the pair of convex curved surfaces are formed adjacent to the pair of gripping surfaces, the operation of gripping the tube by the pair of gripping portions and the operation of releasing the tube from the pair of gripping portions can be performed easily and quickly.

FIG. 2 is a perspective view of the nutrition bottle gantry according to the embodiment of the present invention as viewed from the front upper side. FIG. 3 is a perspective view of the nutrition bottle gantry according to the embodiment of the present invention as seen from above the back surface. FIG. 4: is the perspective view seen from the downward direction of the support for nutrient bottles concerning one Embodiment of this invention. FIG. 5 is a perspective view showing a nutrient bottle mount according to an embodiment of the present invention immediately before the nutrition bottle is held. FIG. 6 is a perspective view showing a nutrient bottle mount according to an embodiment of the present invention immediately after the nutrition bottle is placed. FIG. 7 is a perspective view showing a nutrient bottle gantry according to an embodiment of the present invention in which a nutrition bottle is held and a tube is grasped by a tube grasping portion. FIG. 8 is a perspective view showing a schematic configuration of an example of a nutrition bottle. FIG. 9 is a perspective view of a conventional nutrient bottle mount. FIG. 10 is a perspective view of a conventional nutrition bottle mount on which a nutrition bottle is placed.

  In the nutrition bottle gantry of the present invention described above, it is preferable that the distance between the pair of convex curved surfaces gradually increases as the distance from the pair of gripping surfaces increases. Thereby, the operation | work which hold | grips a tube to a pair of holding part, and the operation | work which releases a tube from a pair of holding part can be performed still more easily.

  The holding part is preferably provided with a plurality of ribs that come into contact with the container body. Thereby, since the area of the part contact | abutted with a container main body becomes small, the attitude | position stability of the nutrition bottle when holding a nutrition bottle on a mount frame can be improved.

  When viewed from above, it is preferable that a through hole is formed in the center of the holding portion. Thereby, it becomes easy to wash | clean the internal peripheral surface of a holding | maintenance part.

  The number of slits is preferably 2 or more. Thereby, two or more tube grips can be provided. Therefore, since the tube gripping part for gripping the tube from two or more tube gripping parts can be arbitrarily selected, a complicated operation such as rotating the gantry according to the direction of the tube handling becomes unnecessary.

  It is preferable that a recess into which another nutrition bottle gantry can be inserted is formed on the lower surface of the nutrition bottle gantry. Thereby, when not using a gantry, a plurality of gantry can be stacked up and down and stored in a space-saving manner.

  In the above, it is preferable that the protrusion part which controls the insertion depth to the said hollow is provided. As a result, it is possible to avoid the inconvenience that it is difficult to separate a plurality of stacked platforms.

  Below, this invention is demonstrated in detail, showing suitable embodiment. However, it goes without saying that the present invention is not limited to the following embodiments. For convenience of explanation, the drawings referred to in the following description show only the main members necessary for explaining the present invention in a simplified manner among the constituent members of the embodiment of the present invention. Therefore, the present invention can include arbitrary components not shown in the following drawings. In addition, the dimensions of the members in the following drawings do not faithfully represent the actual dimensions of the constituent members and the dimensional ratios of the members.

  1 to 4 are perspective views showing a nutrition bottle gantry (hereinafter simply referred to as a “gantry”) 1 according to an embodiment of the present invention, and FIG. 2 is a perspective view as seen from above the front, FIG. 3 is a perspective view as seen from above the back, and FIG. 4 is a perspective view as seen from below. The gantry 1 according to the first embodiment is configured so that the bottle 80 shown in FIG. 8 can be placed thereon.

  The gantry 1 includes a holding unit 2 that holds the bottle 80 and a tube holding unit 3 that holds a flexible tube connected to the port 84 on the bottom 82 of the bottle 80. The holding part 2 and the tube gripping part 3 are integrally formed on a base 4 having a substantially annular shape. An alternate long and short dash line 1 a is a central axis of the gantry 1 that passes through the center of the base 4. For convenience of the following description, in the direction of the central axis 1a, the side of the base 4 is referred to as the “lower side” of the base 1, and the side opposite to the base 4 is referred to as the “upper side” of the base 1. The rotation direction around the central axis 1a is referred to as “circumferential direction”, and the direction orthogonal to the central axis 1a is referred to as “radial direction”.

  The holding part 2 as a whole has a substantially cylindrical shape with the central axis 1a as the central axis. A large-diameter portion 25 is formed on the upper side and a small-diameter portion 26 is formed below the large-diameter portion 25 on the inner peripheral surface of the holding portion 2 (the surface on the side facing the central axis 1 a). The large diameter part 25 and the small diameter part 26 are substantially cylindrical surfaces coaxial with the central axis 1 a, and the large diameter part 25 has a larger distance from the central axis 1 a than the small diameter part 26. A stepped surface 27 is formed between the large diameter portion 26 and the small diameter portion 26 to connect the two. The step surface 27 is a substantially conical surface inclined at a large angle with respect to the central axis 1a. When the bottle 80 is placed on the gantry 1 (see FIG. 7 described later), the large diameter portion 25 faces the side wall 82 of the container body 81 of the bottle 80, and the stepped surface 27 faces the bottom portion 83 of the container body 81.

  The holding portion 2 is formed with a pair of slits 23 that reach the base portion 4 from the upper end downward. When viewed along a direction parallel to the central axis 1a, the pair of slits 23 are disposed at asymmetric positions with respect to the central axis 1a. As a result, the holding unit 2 is opposed to the first holding unit 21 and the first holding unit 21 having a substantially “C” -shaped plan view shape (a shape viewed along a direction parallel to the central axis 1 a). The second holding part 22 is divided in the circumferential direction. The first holding part 21 has a relatively large circumferential dimension compared to the second holding part 22.

  The large-diameter portion 25 and the inclined surface 27 are formed with a plurality of ribs 28 that are continuous with each other. The rib 28 extends along a plane including the central axis 1a. The tops of the ribs 28 are formed along the outer shapes of the side walls 82 and the bottom 83 of the container body 81 of the bottle 80 placed on the gantry 1. In the present embodiment, four ribs 28 are formed on the first holding portion 21 and two ribs are formed on the second holding portion 22, respectively, but are formed on the first holding portion 21 and the second holding portion 22. The number of ribs 28 to be formed is not limited to this. The plurality of ribs 28 are preferably arranged at equiangular intervals with respect to the central axis 1a. When viewed along a direction parallel to the central axis 1a, the angle (arrangement angle of the ribs) of any two ribs 28 adjacent in the circumferential direction with respect to the central axis 1a is preferably less than 90 °. By arranging the ribs 28 at an arrangement angle of less than 90 ° with respect to the central axis 1a, the bottle 80 can be held more stably with less inclination.

  The distance between the first holding part 21 and the second holding part 22 (that is, the width of the slit 23) is abruptly reduced in the vicinity of the base 4. A tube grip 3 is provided at the lower end of the slit 23. The tube grip 3 is preferably provided at a position lower than the port 84 of the bottle 80 (see FIG. 7 described later) held by the holder 2. The tube gripping portion 3 includes a pair of gripping surfaces 31 that are substantially parallel to the central axis 1a and face in the circumferential direction. A pair of locking projections 32 projecting toward each other are formed at the upper ends of the pair of gripping surfaces 31. The distance between the pair of locking projections 32 is smaller than the distance between the pair of gripping surfaces 31. A pair of convex curved surfaces 33 is formed adjacent to the pair of gripping surfaces 31. The pair of convex curved surfaces 33 are smooth curved surfaces that are opposed to each other in the circumferential direction across the slit 23 and are convex toward each other. The distance between the pair of convex curved surfaces 33 is minimum on the pair of gripping surfaces 31 side, and gradually increases as the distance from the pair of gripping surfaces 31 increases. More specifically, as can be understood from FIG. 1, when a pair of convex curved surfaces 33 is viewed along a direction (radial direction) perpendicular to the central axis 1a, the interval between the convex curved surfaces 33 is a pair of relations. In the stop protrusion 32 (that is, on the side of the pair of gripping surfaces 31), it becomes the smallest, and gradually increases as it goes upward. Further, as can be understood from FIG. 3, when the pair of convex curved surfaces 33 is viewed along the direction parallel to the central axis 1a, the interval between the one convex curved surfaces 33 is minimized on the pair of gripping surface 31 sides. From now on, it gradually increases as it approaches the central axis 1a. Thus, the pair of convex curved surfaces 33 are smooth curved surfaces whose intervals gradually change in the vertical direction and the radial direction.

  The pair of gripping surfaces 31 and the pair of locking projections 32 are arranged along three sides of the four sides constituting the rectangle when viewed along a direction (radial direction) perpendicular to the central axis 1a. . As a result, when the pair of gripping surfaces 31 and the pair of locking projections 32 are formed by resin molding, a quadrangular prism-shaped nest extending in the radial direction can be used. The moldability of the locking protrusion 32 is improved.

  Protrusions 41 and 42 projecting outward are formed in a region on the base 4 side of the outer peripheral surface 24 of the first holding part 21 and the second holding part 22 constituting the holding part 2. As a result, the outer diameter of the holding portion 2 is rapidly changed at the step portions 41a and 42a at the upper ends of the protruding portions 41 and 42.

  As can be understood from FIG. 4, a recess 45 having a shape substantially similar to the outer shape of the holding portion 2 described above is formed on the lower surface of the gantry 1. Therefore, the plurality of mounts 1 can be stacked in the vertical direction by inserting the holding portion 2 of another mount 1 into the recess 45 on the lower surface of the mount 1. Thereby, when the gantry 1 is not used, the plurality of gantry 1 can be stored in a space-saving manner. Moreover, the mount frame 1 can be reduced in weight.

  In order to facilitate such stacking of the plurality of mounts 1, the first holding part 21 and the second holding part 22 constituting the holding part 2 are gradually smaller in outer dimension in the radial direction and the circumferential direction as the upper side. The so-called “tapered shape” is preferable. For example, the outer peripheral surface (surface opposite to the central axis 1 a) 24 of the holding unit 2 (that is, the first holding unit 21 and the second holding unit 22) gradually decreases from the central axis 1 a toward the upper side. A conical surface is preferable, and the inner peripheral surface (surface on the central axis 1a side) of the holding portion 2 is preferably a conical surface whose distance from the central axis 1a gradually increases toward the upper side. Moreover, it is preferable that the dimension of the circumferential direction of the 1st holding | maintenance part 21 and the 2nd holding | maintenance part 22 becomes small gradually as the upper side (in other words, the width | variety of the slit 23 becomes large as the upper side).

  When the holding portion 2 of the lower gantry 1 is inserted into the recess 45 on the lower surface of the upper gantry 1 and the two upper and lower gantry 1 are stacked, the protrusions 41 and 42 of the lower gantry 1 (especially, Since the step portions 41a and 42a) collide with the base 4 of the upper gantry 1, the insertion depth of the lower gantry 1 with respect to the upper gantry 1 is restricted. As a result, it is possible to avoid the inconvenience that it becomes difficult to separate the upper and lower frames 1 by inserting the lower frame 1 deeply into the upper frame 1.

  As shown in FIG. 3, a through hole 43 is formed in the center of the base 4. It is easy to clean the inner peripheral surface (particularly, the small diameter portion 26) of the holding portion 2 by passing a finger through the through hole 43 or the like.

  The method for manufacturing the gantry 1 of the present embodiment is not particularly limited, but it can be preferably manufactured integrally by injection molding using a resin material. As the resin material, a hard resin having a mechanical strength that does not substantially deform when the bottle 80 is placed is preferable. Specifically, polycarbonate, polyacetal, polypropylene, hard polyvinyl chloride, nylon or the like can be used.

  A method of using the gantry 1 of the present invention configured as described above will be described.

  FIG. 5 is a perspective view showing a state immediately before the bottle 80 is placed on the gantry 1. The bottle 80 stores a predetermined amount of liquid used for enteral nutrition therapy, for example. In FIG. 5, 90 is a flexible tube connected to the port 84 of the bottle 80. At this stage, the tube 90 is closed with a clamp (not shown) or the like so that the liquid material does not flow through the tube 90.

  As shown in FIG. 5, the bottle 80 is lowered toward the gantry 1 with its bottom 83 facing down. The tube 90 is inserted into the slit 23, and the bottom 83 is inserted between the first holding part 21 and the second holding part 22 of the gantry 1.

  FIG. 6 is a perspective view showing a state immediately after the bottle 80 is placed on the gantry 1. Although not shown, the plurality of ribs 28 (see FIGS. 1 to 3) of the gantry 1 abut against the bottom 83 and the side wall 82 of the container body 81. Thereby, the bottle 80 is held in an upright state. By limiting the portion of the gantry 1 that abuts the bottle 80 to a limited small area of only the tops of the plurality of ribs 28, the bottle 80 is held on the gantry 1 without increasing the shape accuracy of the gantry 1 and the bottle 80. The posture stability of the bottle 80 when it is made to improve is improved. The outer diameter of the tube 90 is larger than the distance between the pair of locking protrusions 32. Therefore, the tube 90 is held by the pair of convex curved surfaces 33 above the pair of locking projections 32.

  Next, the gantry 1 and the bottle 80 are held with one hand, the tube 90 led out from the slit 23 of the gantry 1 is held with the other hand, and the tube 90 is moved downward from the base 4. The tube 90 is pulled so as to be pulled out from. Due to the downward component of the tension applied to the tube 90, the tube 90 passes between the pair of convex protrusions 33 and between the pair of locking projections 32, and a pair of grips below the pair of locking projections 32. Move between the surfaces 31. At this time, the convex curved surface 33, particularly the portion above the locking projection 32 of the convex curved surface 33 functions as a guide surface that guides the tube 90 between the pair of locking projections 32. Therefore, the tube 90 can be easily gripped by the tube gripping portion 3 (that is, between the pair of gripping surfaces 31) with a slight tension.

  FIG. 7 is a perspective view showing a state in which the bottle 80 is held on the gantry 1 and the tube 90 is gripped by the tube gripping portion 3. In this state, the bottle 80 and an enteral feeding catheter (not shown) inserted into the patient are communicated with each other via the tube 90, and the liquid in the bottle 80 is administered to the patient.

  In the state of FIG. 7, when an unintended tension is applied to the portion of the tube 90 derived from the tube gripping portion 3, a frictional force is generated between the outer peripheral surface of the tube 90 and the gripping surface 31, and this friction is generated. The force opposes the tension applied to the tube 90. Contrary to the above, even when a pressing force that pushes the tube 90 into the tube gripping portion 3 is applied to the portion of the tube 90 led out from the tube gripping portion 3, the outer peripheral surface of the tube 90 and the gripping surface 31 The frictional force between them opposes the pressing force. As described above, when an external force is applied to the tube 90 led out from the tube gripping portion 3, the tube gripping portion 3 functions to reduce the transmission of the external force to the port 84 via the tube 90. Therefore, since the external force applied to the tube 90 is unlikely to act on the bottle 80, when the external force is applied to the tube 90, the posture change of the bottle 80 to which the tube 90 is connected can be suppressed.

  In order for the tube gripping portion 3 to effectively counter the external force acting on the tube 90, the distance between the pair of gripping surfaces 31 is substantially the same as or slightly smaller than the outer diameter of the tube 90 when no load is applied. It is preferable to set it small. However, even if the distance between the pair of gripping surfaces 31 is larger than the outer diameter of the tube 90, if an external force is applied to the tube 90, the tube 90 is displaced and in most cases contacts the gripping surface 31. It is possible to suppress the posture change of the bottle 80 in the same manner as described above.

  Since the pair of locking projections 32 are formed above the pair of gripping surfaces 31, the tube 90 is locked by a pair of unintentional external forces applied to the portion of the tube 90 derived from the tube gripping portion 3. There is a low possibility of passing between the protrusions 32 and moving upward. Therefore, since the tube 90 can be stably held by the tube holding part 3, the posture change of the bottle 80 can be suppressed for a long time.

  Since the holding part 2 is formed with the slit 23 extending in the vertical direction, the amount of the liquid substance in the bottle 80 can be visually recognized through the slit 23.

  When the administration of the liquid material is completed, the tube 90 is closed with, for example, a clamp (not shown). Next, the gantry 1 is held with one hand, the bottle 80 is held with the other hand, and the bottle 80 is moved upward with respect to the gantry 1 so as to separate the gantry 1 and the bottle 80. Since the tube 90 connected to the port 84 of the bottle 80 is gripped by the tube grip 3, tension is applied to the portion of the tube 90 between the port 84 and the tube grip 3. Due to this tension, the tube 90 moves from between the pair of gripping surfaces 31 to the upper side of the pair of locking projections 32 through the pair of locking projections 32. At this time, the convex curved surface 33, particularly the portion of the convex curved surface 33 closer to the central axis 1a than the gripping surface 31 (see FIG. 3) guides the tube 90 so that the tube 90 is away from the central axis 1a. Therefore, the tube 90 can be easily released from the tube gripping portion 3 (that is, between the pair of gripping surfaces 31) with a slight tension. Thus, the bottle 80 and the gantry 1 can be separated. The empty bottle 80 is disassembled and washed.

  As described above, in the gantry 1 of the present embodiment, the tube gripping portion 3 formed at the lower end of the slit 23 formed in the holding portion 2 grips the tube 90, so that the tube gripping portion 3 is led out to the outside. Even if an unintended external force is applied to the tube 90, the posture of the bottle 80 held on the gantry 1 is unlikely to change. Therefore, the posture stability of the bottle 80 is excellent. Thereby, for example, during the enteral nutrition therapy, troublesome work such as correcting the posture of the bottle 80 can be reduced, and the burden on the operator is reduced.

  Since the locking projections 32 are formed above the pair of gripping surfaces 31 constituting the tube gripping portion 3, the tube 90 gripped by the tube gripping portion 3 escapes from the tube gripping portion 3 by an unintended external force. The possibility can be reduced. Therefore, the posture change of the bottle 80 can be suppressed over a long period of time.

  The pair of locking protrusions 32 prevent the tube 90 held by the tube holding portion 3 from escaping from the tube holding portion 3, so that the tube 90 is held by the tube holding portion 3 as shown in FIG. When the bottle 80 is lifted, the gantry 1 can be lifted together through the tube 90. Therefore, for example, during the enteral nutrition therapy, it is possible to lift only the bottle 80 with one hand and change the positions of the gantry 1 and the bottle 80.

  Since the tube gripping portion 3 is formed at the lower end of the slit 23, compared with the state of FIG. 6, in the state where the tube gripping portion 3 is gripped as shown in FIG. The bending of the portion between the port 84 and the tube gripping portion 3 becomes small. Therefore, a so-called kink phenomenon that the portion of the tube 90 is bent and the internal space is crushed is difficult to occur. In addition, in order to prevent kinking from occurring in the tube 90 in a state where the tube 90 is gripped by the tube gripping portion 3, there is no need to increase the vertical distance between the holding portion 2 and the tube gripping portion 3. The height of the gantry 1 can be kept low.

  Since the pair of convex curved surfaces 33 are formed adjacent to the pair of gripping surfaces 31, the operation of gripping the tube 90 by the pair of gripping portions 3 and the operation of releasing the tube 90 from the pair of gripping portions 3 are easy and quick. Can be done.

  Two slits 23 are formed in the holding part 2, and a tube gripping part 3 is formed at the lower end of each slit 23. Therefore, the operator can hold the tube 90 by any one of the two tube holding portions 3. Thereby, the tube gripping part 3 that grips the tube 90 can be selected according to the direction in which the tube 90 is routed without changing the orientation of the gantry 1. For example, the tube 90 is fixed to the tube gripping portion 3 provided in the slit 23 facing the patient, and the operator can store the remaining amount of liquid in the bottle 80 through another slit 23. Can be visually recognized.

  The above embodiments are merely examples. The present invention is not limited to the above embodiment, and can be modified as appropriate.

  In the embodiment described above, the two slits 23 are formed in the holding unit 2, but the number of the slits 23 may be one or three or more. When forming the plurality of slits 23, the plurality of slits 23 may be arranged at equiangular intervals with respect to the central axis 1a, or may be arranged at non-equal angular intervals.

  In the above embodiment, the ribs 28 are continuously formed on the large diameter portion 25 and the inclined surface 27, but may not be continuous. Further, the ribs 28 may be formed on only one of the large diameter portion 25 and the inclined surface 27. Instead of the ribs 28, projections having an arbitrary shape (for example, spherical projections) may be provided. Furthermore, the ribs 28 and the projections that replace them may be omitted.

  In the above embodiment, the pair of locking protrusions 32 are formed so as to face each other with the slit 23 interposed therebetween, but either one of the locking protrusions 32 may be omitted. The shape of the locking protrusion 32 is not limited to the above embodiment, and can be arbitrarily set.

  The central through hole 43 may be omitted.

  In the above embodiment, the protrusions 41 and 42 are provided on the outer peripheral surface 24 of the holding part 2 as a mechanism for restricting the insertion depth when the plurality of mounts 1 are stacked in the vertical direction. It may be provided in another place to exhibit the same function. Further, the insertion depth may be regulated by using another structure instead of the protrusions 41 and 42. Furthermore, the protrusions 41 and 42 may be omitted.

  The depression 45 on the lower surface of the gantry 1 that allows the gantry 1 to be stacked in the vertical direction can be omitted.

  In the above embodiment, the small-diameter portion 26 that is a substantially cylindrical surface is provided below the step surface 27, but the shape of the portion below the step surface 27 is arbitrary. For example, an arbitrary curved surface such as a spherical surface may be used.

  The configuration of the bottle 80 held on the gantry of the present invention is not limited to FIG. 8 and is arbitrary. The container main body 81 of the bottle 80 should just have the cylinder shape which can accommodate a liquid substance. The side wall 82 of the container main body 81 has a substantially cylindrical surface in the above-described embodiment, but may have an arbitrary shape such as a conical surface or a polygonal column surface (for example, a hexagonal column surface). Depending on the shape of the container body 81, the shapes of the large-diameter portion 25 and the stepped surface 27 facing the side wall 82 and the bottom portion 83 of the container body 81 can be changed as appropriate. The container body 81 only needs to have a mechanical strength (rigidity) that can maintain a predetermined shape, and the material is a resin material (for example, polypropylene, polycarbonate, etc.) having shape-retaining properties, glass, or the like.
