no. 1 approach

[0036] figure 1 and figure 2 It is a perspective view of the syringe driving device 1 in the first embodiment of the present invention. The syringe driving device 1 is a device for supporting an operator who uses the syringe 201 to perform a dispensing operation. As a dispensing operation, for example, it is the mixing operation of injection medicine or drip medicine. In the present embodiment, this dispensing operation includes from the medicine bottle 301 (referring to Figure 8A and Figure 8B ) means the operation of sucking the drug solution into the syringe 201 from the drug solution container, and conversely the operation of injecting the drug solution from the syringe 201 into the vial 301 . The syringe 201 includes an outer cylinder 202 with an injection needle 204 attached to its distal end; A flange portion 202 a is provided on the opening end side of the outer cylinder 202 , and a jaw portion 203 a is provided on the rear end side of the piston 203 .

no. 2 approach

[0093] In the first embodiment, the internal pressure of the vial 301 is calculated based on the drive current of the motor 17. On the other hand, Figure 9 and Figure 10 The illustrated second embodiment of the present invention detects the stress received by the piston operating unit 4 from the piston 203 and calculates the internal pressure of the vial 301 using the stress. Specifically, the main body 402 of the syringe driving device 401 according to the present embodiment includes a stress detection unit 52 including stress sensors 51A and 51B mounted on opposite groove walls of the groove 14 of the piston operation unit 4 . . As described above, the jaw portion 203a of the piston 203 is accommodated in the groove 14 of the piston operating portion 4 , and the locking claw 16 locks the connecting portion 15 in the closed state, thereby connecting the jaw portion 203a to the piston operating portion 4 . In this state, when a load in the pulling direction (direction of a...

Abstract

A syringe drive device (1) is provided with a syringe holding section (3), a piston operation section (4), and a display section (6). The outer tube (202) of a syringe (201) is removably held by the syringe holding section (3). The piston (203) of the syringe (201) is removably engaged with the piston operation section (4). The piston operation section (4) is moved in the direction corresponding to the operation of operation buttons (8A, 8B), and this causes the piston (203) to move in the direction in which the piston is pushed into or pulled out of the outer tube (202). The pressure within a medication solution container into which a syringe needle (204) mounted to the outer tube (202) of the syringe (201) is inserted is measured and displayed on the display section (6).

Description

technical field [0001] The present invention relates to a syringe driving device for moving a plunger (plunger) of a syringe relative to an outer cylinder (cylinder) used in dispensing operations such as injection medicine or drip medicine mixing. Furthermore, the present invention relates to a dispensing device to which such a syringe driving device is applied. Background technique [0002] Usually, in the mixing operation of injection medicine or drip medicine, the work of aspirating the medicine solution in the medicine bottle (medicine solution container) into the syringe or injecting the medicine solution in the syringe into the medicine bottle is performed manually. In these operations, the inner space of the syringe and the vial is formed into a closed space by piercing the rubber stopper of the vial with an injection needle attached to the tip of the syringe. [0003] When sucking the drug solution in the vial into the syringe, move the plunger of the syringe in the...
