A drug transferring needle includes a needle base portion, a first needle portion having therein an air passage, and a second needle portion longer than the first needle portion and arranged parallel to the first needle portion. In the first needle portion, a first air vent being one end of the air passage is provided on a distal end side of the second needle portion from a second air vent being the other end of the air passage. In the second needle portion, one end of a liquid passage is connected to the inside of the needle base portion, and the other end thereof is a liquid pass opening of the second needle portion. The second needle portion has a distal end having the liquid pass opening, a base portion connected to the needle base portion, and an intermediate portion connecting the distal end and the base portion.

Drug transferring needle and drug transferring method

An omni-directional electric vehicle includes: a body having a chair portion; an operation detection unit which detects an operation direction and an operation amount of an operation input; a travel control information generation unit which generates, based on the operation direction and the operation amount, travel control information including (i) a target straight-movement speed for moving the body in a forward/backward direction and (ii) a target rotation speed for rotating the body about a rotation center; and a control unit which drives a movement mechanism of the body according to the travel control information. The travel control information generation unit-changes, based on the target straight-movement speed, the rotation center for the target rotation speed from a reference position which is set virtually and fixedly to the body in the forward/backward direction.

Electric vehicle and method for controlling electric vehicle

A lifting apparatus includes an upper frame, a base frame, a link mechanism for connecting the upper frame and the base frame, and a linear actuator connected to the link mechanism for driving the link mechanism. The link mechanism includes at least a T-shaped first arm slidably supported on the base frame or the upper frame and provided with connections at four points, and an L-shaped second arm provided with connections at three points.

An electric vehicle which travels by driving actuators includes: a monitor unit which monitors external environment or internal environment of the electric vehicle; an alarm unit which outputs, based on monitoring information obtained by the monitoring unit, a vibration velocity signal indicating velocity which changes in a cycle; a travel information generation unit which calculates a target travel velocity based on a steering direction and a control input provided by an operator of the electric vehicle, and generates travel control information for controlling the actuators based on the target travel velocity; and a control unit which controls the actuators based on the travel control information. The travel information generation unit regenerates the travel control information by adding the vibration velocity signal to the target travel velocity upon receiving the vibration velocity signal.

A syringe drive deviceincludes a fixing sectionfixing an outer tube, a movable holderholding a plunger, and a drive sectiondriving the holderalong an axis of the plunger to push and pull the plunger with respect to the outer tube. An internal pressure detectorhas a positive pressure detection switchdetecting an internal pressure of a syringe. A determination sectiondetermines the issuance of an alert when the holderis stopped and the positive pressure detection switchis ON. A display sectionis lit to indicate the alert when the determination sectiondetermines to issue the alert.

A medicinal solution injection apparatusincludes a composite needleincluding a needle base portion, an injection needle, and an adjustment needle, a pressure generating portionconfigured to discharge a compressed air, a measuring portionconfigured to measure a filling amount and a filling speed of a medicinal solution by measuring a position of a gasketof a syringe, and a control portionconfigured to control the pressure generating portionand the measuring portion. The compressed air is introduced into a vial containerthrough an edgeof the adjustment needlelocated above a liquid surfaceof the medicinal solution in the vial container(outside the liquid surface) to press the liquid surfaceof the medicinal solution downward, so that a medicinal solutionis injected into the syringethrough an edgeof the injection needlein the medicinal solution. The medicinal solution injection apparatuscan accurately and efficiently inject the medicinal solutionof the vial containerinto the syringewhile suppressing the medicinal solutionfrom foaming.

A syringe drive deviceaccording to the present invention includes: an outer tube fixing portionthat detachably fixes an outer tubeof a syringe; a plunger holderthat holds a plungerof the syringe; and a drive portion that moves the plunger holderalong an axis of the syringe. The outer tube fixing portionincludes: a flange catcherfacing a rear end of a flangeof the outer tube, the rear end being located far from the plungerto be pushed; slide portionsandthat are located in front of a front end of the flangeto hold the flangebetween the flange catcherand the slide portions, the front end being located close to the plungerto be pushed; slide guidesandthat support the slide portionsandso as to be slidable along the axis of the syringe; and a slide portion operation mechanism that is switchable between a first state where the slide portionsandslide along the axis of the syringe, and a second state where the slide portionsandare held at positions to hold the flangebetween the flange catcherand the slide portions.

Syringe drive device

A syringe drive deviceincludes a cylinder holding sectionconfigured to detachably hold a cylindera piston manipulating sectiondetachably coupled with a piston, and a piston drive sectionincluding racksA andB coupled with the piston manipulating sectionand configured to move the piston manipulating sectionso that a pistonis moved in a push-in direction or a pull-out direction. A cylinderA having a given capacity (for example, 50 cc) is directly loaded in the syringe drive devicewith no adapter therebetween. A syringeC having a different capacity (for example, 20 cc) is loaded in the syringe drive deviceby means of a cylinder adapterand a piston adapter

A syringe drive device drives a syringe including a cylindrical cylinder and a piston. The cylinder includes a solution supply port at one end, and an opening at the other end. The piston is inserted into the cylinder through the opening. The syringe drive device includes a cylinder holder to rotatably hold the cylinder of the syringe, and a piston driver to drive the piston in its axial direction with respect to the cylinder held in the cylinder holder.
