When the infusion is started, the slider 111 is driven in the direction of the arrow by a built-in mechanism (not shown) so that accurate liquid feeding is performed via the infusion tube shown in the figure.

  The installation tools 1 and 1 according to the present invention are fixed at an arbitrary height and rotation position by operating the knob 202 of the clamp device 200 with respect to a pole 300 which is fixed upright from the infusion stand 301 as shown in the figure. The

  FIG. 1 shows the state where two installation tools 1 are fixed in the vertical direction, but one unit may be used. For example, in the case of intensive care in which a large number of drug solutions are sent simultaneously, three or more units are fixed. Needless to say, it is used. Each installation tool 1 includes a base portion 2 in which a placement surface 3 on which a bottom surface 104 of a syringe-type infusion device 100 is placed is formed obliquely as illustrated. As will be described later, all the components described below are inserted and fixed from the back side of the base 2 so that screws are not exposed on the external surface.

  The base 2 is stably and inexpensively prepared by injection molding from a resin material containing engineering plastic. Further, a large number of ribs that also serve to prevent uneven thickness are integrally formed in view of injection molding, and a metal part is formed by insert molding at a portion where a screw is screwed. Of course, it is also possible to prepare the base 2 from a metal other than a resin molded product, wood, a hybrid material of resin and metal, or the like.

  The width dimension W1 of the mounting surface 3 of the base 2 is set to be less than the distance W2 between the concave portions 109 and 109, and when the bottom surface 104 of the syringe-type infusion device 100 is mounted on the mounting surface 3 The respective concave portions 109 on the front surface side of the apparatus base portion 103 infiltrate into the wall portions 14 and 14 on the mounting surface 3 so that positioning in the left-right direction can be performed automatically.

The guard portion 7 continuously forms a wall portion that covers the entire operation lever 8 as shown in the figure, and, for example, secures a space for the index finger between the operation lever 8 and rotates the operation lever clockwise as described later. Operable in the direction. Further, for example, consideration is given to preventing an erroneous operation in which the operation lever 8 is operated by colliding with another object during movement. Here, the operation lever 8 is provided on the right side because it is a right-handed configuration, but a left-handed person is provided with an operation lever on the left side, and the rotating member is also formed in a left-right manner. Will also be good.

  A window portion 13 for exposing an operation indicator portion indicating that the first rotating member 11 is in the locking position is formed in a conspicuous portion of the base portion 2. The base 2 may further be provided with a communication unit 10 for exchanging desired information with the syringe-type infusion device 100 and a pair of contacts 9 for supplying DC power.

  FIG. 2 is an exploded view illustrating a state in which the clamp device 200 is fixed to the installation tool 1. In this figure, components and components that have already been described are denoted by the same reference numerals and description thereof is omitted. The clamp device 200 includes a base 201 and a gripping member 203 that moves forward and backward by the operation of the knob 202. A countersunk screw hole 205 is formed in four locations in 201.

  In order to fix the clamping device 200 to the installation tool 1, it is fixed to the installation tool 1 using four countersunk screws 206. For this fixing, the base 2 is formed with four studs 2a having insert screw holes. Positioning in the left-right direction is performed so that the first rotating member 11 and the second rotating member 12 are positioned in the space between the four studs 2a.

  In addition, two sub-assemblies 20 in which the first rotating member 11 and the second rotating member 12 are assembled in advance as shown in the figure are fixed to the base 2 using two screws 18. An insert screw hole 2 b for a metal part is formed in the base 2. Furthermore, a hole 2c for inserting the boss 8b of the operating lever 8 is formed on the bottom surface of the guard portion 7 of the base 2, and the screw hole 8c of the insert part of the operating lever 8 is formed in this hole 2c. After the insertion, the hexagon socket head screw 29 is used to screw together with the D-cut surface 31a of the stainless steel first shaft body 31 of the subassembly 20 so as to be integrally fixed. .

  In the above configuration, first, the subassembly 20 is set so that the engaging portions of the first rotating member 11 and the second rotating member 12 come out of the opening 15 (shown by broken lines). Thereafter, the two screws 18 are inserted into the holes 23 of the sub base 22 and fixed to the insert screw holes 2 b of the base 2. Following this, the operating lever 8 is inserted into the hole 2 c and fixed to the first shaft body 31 with a hexagon socket head screw 29. Next, the cover body 16 is put on, and the countersunk screws 206 are passed through the four countersunk screw holes 205 of the base 201 of the clamp device 200, and are fastened together with the stud 2a to complete.

  As described above, in particular, consideration is given to simplify the assembly process by preparing in advance the subassembly 20 provided with the first rotating member 11 and the second rotating member 12. Here, it goes without saying that individual components may be directly assembled to the base 2.

  FIG. 3 is an exploded view of the subassembly 20. In this figure, the same reference numerals are given to the components or parts already described, and the description is omitted. The sub-base 22 is a resin part in which holes 24 and 25 are integrally formed at left and right symmetrical positions as shown in the figure. Be prepared. The second shaft body 32 is set in the lower hole portion 25 after passing through the hole portion 12 a of the second rotating member 12. Further, the first shaft body 31 is set in the upper hole portion 24 after passing through the hole portion 11 a of the first rotating member 11. The first rotating member 11 includes a first locking portion 11b having a shape for locking the second locked groove 102 of the infusion device 100, a projection portion 11c for setting the compression coil spring 41, and stopper means described later. The protrusion 11g (shown by a broken line) and the operation indicator 11k are formed using an engineering plastic resin material. In addition, the second rotating member 12 is provided adjacent to the first rotating member 11 after assembly, and a contact surface 12t with which the protruding portion 11g contacts, and is formed continuously from the contact surface 12t, and the protruding portion 11g. A groove portion 12g having a shape into which the water enters and a reinforcing portion 12f and a projection portion 12c for setting the compression coil spring 42 are formed using an engineering plastic resin material. Here, although the assembly work is simplified by using a compression coil spring as the urging member, it goes without saying that a tension coil spring and a torsion spring, which are limited thereto, may be used.

  4A is an external perspective view of the subassembly 20 viewed from the front side after completion, and FIG. 4B is an external perspective view of the subassembly 20 viewed from the back side after completion. In FIG. 4A, the first rotating member 11 and the second rotating member 12 are adjacent to each other, and are configured such that the locking portions 11b and 12b are located at the same position.

  4B, the protrusion 11g of the first rotating member 11 is located on the contact surface 12t of the second rotating member 12. Further, after the screws are fixed, the rotating members are fixed so as to be positioned in the left-right direction by the studs 2a (shown by broken lines).

  As described above, the first rotating member 11 is fixed by the first shaft body 31 and the second rotating member 12 is individually fixed by the second shaft body 32 to constitute the stopper means.

  FIG. 5A is a cross-sectional view for explaining the operation of the stover means before the syringe-type infusion device 100 is attached. In this drawing, the same reference numerals are given to the components or parts already described, and the description is omitted. The first shaft body 31 is disposed on the base 2 in parallel with the mounting surface at a position close to the mounting surface 3. Has been. Further, the second shaft body 32 is disposed on the base portion in parallel with the placement surface at a position far from the placement surface 3.

  And the mounting tool 1 is provided with the mounting surface 3 which becomes the angle (alpha) of about 60 with respect to a horizontal surface. By providing the mounting surface 3 in this manner, the locking portion 4 that locks the first locked groove 101 of the syringe-type infusion device 100 shown by a one-dot chain line in the drawing can be a pivotal support point. As a result, the syringe-type infusion device 100 can be tilted forward, and even a weak nurse can be easily removed from the placement surface. That is, it is not necessary to support the entire weight of the syringe-type infusion device 100.

  In addition, by using the syringe-type infusion device 100 in a state inclined toward the front, the operation status can be confirmed from a distant position. In addition, a chamfered portion 121a is formed between the second locked groove 102 and the bottom surface 104 of the back surface 121 of the device base so as to come into contact with the locking portions 11b and 12b without difficulty. By setting in the arrow D1 direction, each rotating member can be rotated against the urging force of the compression coil spring.

  In the drawing, the first rotating member 11 is illustrated by a solid line, the second rotating member 12 is illustrated by a broken line, and the operation lever 8 is illustrated by a one-dot chain line. The groove portion 11g continuously formed from the contact surface 12t of the second rotating member 12 is separated from the second shaft body 32 ”by a first distance L1, while the protrusion portion 11g is separated from the first shaft body 31 by the first shaft body 31g. The distance L2 is separated by a second distance that is approximately twice the distance.

  From the above state, when the syringe-type infusion device 100 is set in the direction of the arrow D1, the engaging portion rides on the chamfered portion 121a, and the rotating members 11 and 12 are rotated clockwise. Thereafter, the respective rotating members 11, 12 are rotated counterclockwise by the action of the compression coil springs 41, 42, whereby the respective engaging portions 11 b, 12 b enter the second locked grooves 102.

  As a result, the state shown in the operation explanatory diagram of the stover means after the syringe-type infusion device 100 of FIG. From this state, even if the syringe-type infusion device 100 is pulled to the near side in the direction of the arrow D2, since the projection 11g is locked to the contact surface 12t, the rotating members 11 and 12 cannot be rotated. It will keep the stopped state.

  Next, FIG. 6A is a cross-sectional view for explaining the operation of the stover means after the operation lever 8 is operated after the syringe-type infusion device 100 is mounted. As shown in the figure, when the operating lever 8 is rotated with the fingertip in the clockwise direction (arrow D3), the first rotating member 11 fixed to the operating lever 8 is similarly rotated in the clockwise direction. As a result, the protrusion 11g is positioned on the groove 12g from the contact surface 12t. At the same time, the locking portion 11 b of the first rotating member 11 is retracted from the second locked groove 102.

  Subsequently, in FIG. 6B, when the syringe-type infusion device 100 is taken out from the placement surface 3 in the direction of arrow D4, the locking portion 12b of the second rotating member 12 slides on the second locked groove 102. The retraction position is achieved by rotating the protrusion 11g into the groove 12g. Therefore, the syringe-type infusion device 100 can be taken out. Thereafter, when the operation of the operation lever 8 is stopped, the state shown in FIG.

  Finally, FIG. 7A is a side view illustrating the positional relationship where the operation indicator 11k exits from the window portion 13, and FIG. 7B is an external perspective view thereof.

  As shown in the drawing, an arrow 7 a indicating the operation direction of the operation lever 8 is printed or integrally formed on the bottom surface of the guard portion 7 of the operation lever 8.

  As described above, the infusion device including the syringe-type infusion device 100 can be attached and detached and can be held in a fixed state at the mounting position, and the operation lever 8 can be used as a stopper means for bringing the infusion state into the non-locking state. By providing, the medical staff can easily attach and detach and replace. As a result, it is possible to respond quickly, especially in an emergency, and the contribution becomes large.
