FIG. 4 is a cross-sectional view showing the holding device 20 according to the first embodiment of the present invention.
The syringe 21 is formed entirely or partially from a transparent material, and can visually check the chemical solution stored inside. Examples of the material of the syringe 21 include plastic and glass. A rubber stopper 41 as a stopper member is attached to the tip of the syringe 21 that stores the chemical solution. Examples of the material of the rubber plug 41 include materials such as butyl rubber, silicone rubber, and elastomer. The proximal end side of the chemical solution stored in the syringe 21 is sealed with a gasket 80, and the chemical solution is pushed forward by moving the gasket 80 to the distal end side during use.

  In FIG. 4, the holding device 20 includes the holding body 22, the grip portion 23, and the pedestal 14 as described above. The holding part 23 of the holding device 20 includes an outer case 31 having an opening 33 whose side facing the syringe 21 is opened, and a claw mechanism 34 that is disposed in the outer case 31 and holds the syringe 21. ing.

  The claw mechanism 34 slides up and down inside the outer case 31. The claw mechanism 34 includes a claw portion 36 having a plurality of freely openable and claw provided at the tip thereof, and a claw holding rod 37 that pivotally supports the claw portion 36. A spring 45 that biases the claw mechanism 34 outward in the axial direction of the outer case 31 is provided, and movement is restricted by a stop ring 39 provided on the claw holding rod 37.

  Here, the nail | claw part 36 is provided with the three nail | claw arrange | positioned by the circumferential direction equal space | interval. In the present invention, the claw portion 36 can be configured with a plurality of claws, but three is most desirable from the viewpoint of accurate centering. FIG. 4 shows a cross section passing through two claws.

  The claw portion 36 can protrude outward from the opening 33 and can be stored, that is, returned to the inner side of the outer case 31 from the opening 33. The claw portion 36 extends to the side of the syringe 21, that is, radially outward when protruding outward from the opening 33, and is narrowed by the inner surface of the outer case 31 when holding the syringe 21 from the side. As described above, the claw portion 36 includes a plurality of claws that can be freely opened and closed, and has a spring function and can return to the original state. Examples of the material of the claw portion 36 include resin materials such as nylon (trade name) having elasticity. However, other materials having elasticity such as metal can also be used. Examples of the material of the outer case 31 include hard materials such as metal.

  The claw mechanism 34 forms a space 46 having a length in the vertical direction in which the rubber stopper 41 attached to the tip of the syringe 21 can be accommodated inside the claw 36. Accordingly, the claw portion 36 can be narrowed in a state where the rubber plug 41 is housed in the space portion 46.

  As described above, the stop ring 39 is provided at the tip (upper end) of the claw holding bar 37, and another claw holding bar 37 is located above the space 46 so that the claw holding bar 37 can move upward. A space 47 is formed in the outer case 31. The outer case 31 is rotatably engaged with the holding body 22 via a bearing 40.

Next, the operation of the syringe holding device 20 configured as described above will be described.
As described above, the syringe 21 has the rubber stopper 41 at the upper end (tip) and the flange 42 at the lower end (base end), and is placed on the base 14 having a substantially conical protrusion at the center. Is done. A shoulder portion 44 is formed below the rubber stopper 41 of the syringe 21. That is, in this case, a shoulder portion 44 is formed at a portion of the syringe 21 that extends downward and beyond the rubber stopper 41.

  FIG. 4A shows a state before the claw mechanism 34 is lowered, and the claw portion 36 protrudes outward from the opening 33. And the nail | claw part 36 is lowered | hung to the side (radial direction, horizontal direction on the paper surface) of the rubber stopper 41 so that a plurality of claws surround the rubber stopper 41 of the syringe 21 in this protruding state. At this time, even when the rubber plug 41 is thick, the rubber plug 41 can be sufficiently stored in the space 46.

  The syringe 21 may be provided with a luer lock made of metal or plastic for fixing the injection needle to the syringe 21. Even when such a luer lock is provided and the rubber plug 41 is thicker than the luer lock, the space 46 can sufficiently accommodate the luer lock and the rubber plug 41 therein. In this state, the holding device 20 can be lowered as indicated by the up and down arrows. The pedestal 14 can be rotated at any time.

  FIG. 4B shows a situation in which the holding body 22 and the gripping portion 23 are lowered as indicated by arrows in accordance with the traveling state of the roller 13 (see FIG. 1) on the cam rail 12. In this situation, a part of the claw mechanism 34, that is, the claw holding rod 37 contacts (abuts) the rubber stopper 41, and further lowering of the claw mechanism 34 is prevented. When the holding body 22 is further lowered in the state where the claw mechanism 34 is prevented from being lowered, the outer case 31 is lowered.

  Due to the lowering of the outer case 31 due to the weight of the holding main body 22, the space portion 46 formed inside the claw portion 36 completely stores the rubber plug 41. At this time, the position of the taper 48 formed on the distal end side of the claw 36 is a position corresponding to the position of the shoulder 44 of the syringe 21.

  FIG. 4C shows a state where the outer case 31 is further lowered. As the outer case 31 descends, the opened claw portion 36 is tightened by the inner surface of the outer case 31 from the outside, gradually narrowed, and closed. At this time, the spring 45 contracts, and the claw holding rod 37 rises in the other space portion 47.

  And the nail | claw part 36 is narrowed and closes completely. When the claw portion 36 is sandwiched and closed, the claw of the claw portion 36 holds the shoulder portion 44 of the syringe 21 firmly. In this case, since the space 46 having a length sufficient to accommodate the rubber plug 41 is formed inside the claw 36, the claw 36 accommodates the rubber plug 41 in the space 46. Thus, the shoulder 44 of the syringe 21 is held avoiding the rubber stopper 41.

Then, a taper 48 formed on the front end side of the claw of the claw portion 36 rides on the shoulder portion 44, whereby a part of the claw mechanism 34 that is in contact with the rubber stopper 41, that is, in this case, the claw holding rod 37. Is lifted upward to form a gap, and contact between the claw mechanism 34 and the rubber plug 41 is eliminated. Therefore, no mechanical force works between both of them. In this state, when the syringe 21 is rotated at a high speed, the rubber plug 41 is not subjected to any mechanical force due to contact.

  As described above, the holding device 20 is used to store the rubber stopper 41 attached to the tip of the syringe 21 in the outer case 31, and the syringe with the gap formed between the claw mechanism 34 and the rubber stopper 41. 21 is held, and a method of holding the syringe 21 is formed so that a mechanical force due to contact is not applied to the rubber stopper 41 of the syringe 21 when the syringe 21 rotates at high speed.

According to the first embodiment, even when the rubber stopper 41 attached to the tip of the syringe 21 is thicker than the syringe 21 or the luer lock, the holding device 20 can store the rubber stopper 41 of the syringe 21. By the claw part 36 forming the part 46, the syringe 21 can be rotatably held while avoiding the rubber stopper 41 of the syringe 21. Moreover, the holding device 20 holds the syringe 21 so that the center of gravity and the rotation center of the syringe 21 are not shifted by the claw portion 36 having a plurality of claws that can be opened and closed, and absorbs manufacturing errors of the syringe 21. Centering can be performed. This is important when the syringe 21 is rotated at a high speed. That is, according to the first embodiment, it is possible to hold the syringe 21 accurately and rotatably without applying a load to the rubber stopper 41 attached to the tip of the syringe 21 containing the chemical solution. Furthermore, the holding device 20 can firmly hold the syringe 21 in the radial direction by wrapping the claw portion 36 with the outer case 31.

(Second Embodiment)
FIG. 5 is a cross-sectional view showing a holding device 20 according to the second embodiment of the present invention. About the part which is common in 1st Embodiment shown in FIGS. 1-4, the structure and description which were shown in FIGS. 1-4 shall be used. The difference from the first embodiment will be mainly described. In addition, the same code | symbol is attached | subjected about the member which has the same function as 1st Embodiment. The same applies to the following embodiments.

  The difference of the second embodiment from the first embodiment is that an outer case 31A corresponding to the outer case 31 of the first embodiment is configured by being separated from the holding main body 22 and can be moved downward through the outer case 31A. It is configured to be driven. Therefore, there is an interval between the holding body 22 and the outer case 31A, and the two are not engaged. The outer case 31 </ b> A can slide on the outside of the claw mechanism 34.

  An annular protrusion 51 is provided on the outer surface of the outer case 31A so as to protrude outward in the radial direction. The protrusion 51 can be held in a groove formed in the plate cam 54 shown in FIG. The groove of the plate cam 54 is formed so as to drive the outer case 31A in the vertical direction as determined in advance.

  The claw mechanism 34 includes a cylindrical inner member 35 that is disposed inside the outer case 31A and is relatively slidably moved up and down within the outer case 31A. Two annular engagement grooves 53 are formed on the outer surface of the inner member 35 of the claw mechanism 34. The distal end of the plunger 52 provided in the outer case 31A engages with any of the engagement grooves 53, and the outer case 31A is positioned. The plunger 52 includes a ball that is urged in the distal direction by a spring member.

  FIG. 6 is a plan view showing the arrangement of the plate cam 54. As shown in FIG. 6, the plate cam 54 is used for switching between the holding section and the opening section.

  In the second embodiment, the outer case 31 </ b> A is a cylindrical outer case portion that is movable upward and downward by the protrusion 51 and the plate cam 54. Here, the protrusion 51 and the plate cam 54 constitute a drive mechanism. The outer case 31 </ b> A is moved up and down slidably on the outer peripheral surface of the inner member 35 of the claw mechanism 34 disposed therein, and is moved up and down by a holding mechanism including a plunger 52 and an engagement groove 53. It is held at a predetermined position in the direction and stopped.

  FIG. 5A shows a state before the claw mechanism 34 is lowered, and the claw portion 36 protrudes outward from the opening 33. And the nail | claw part 36 has spread in the side of the syringe 21, ie, the radial direction, in this protruding state.

  FIG. 5B shows a state in which the holding body 22 and the grip portion 23 are lowered as indicated by arrows in accordance with the traveling state of the roller 13 (see FIG. 1) on the cam rail 12.

  At this time, the plunger 52 is engaged with the upper engaging groove 53, and the outer case 31A and the claw mechanism 34 are fixed and integrated.

  Due to the lowering of the outer case 31 </ b> A by the protrusion 51 and the plate cam 54, the space portion 46 formed inside the claw portion 36 completely accommodates the rubber plug 41. At this time, the position of the taper 48 formed in the claw 36 is a position corresponding to the position of the shoulder 44. In the case of the second embodiment, there is no contact between the claw holding rod 37, that is, the claw mechanism 34 and the rubber stopper 41.

  In this state, the protrusion 51 can be engaged with the plate cam 54, and the outer case 31A can be further lowered. However, the protrusion 51 and the plate cam 54 may be configured to always be engaged on the entire circumference to move the outer case 31A up and down. In this case, the holding mechanism is not always necessary.

  FIG. 5C shows a state where the outer case 31A is further lowered. At this time, the engagement between the plunger 52 and the upper engagement groove 53 is released.

  By the lowering of the outer case 31A, the opened claw portion 36 is tightened from the outside by the inner surface of the outer case 31A, gradually narrowed, and closed.

  Then, the claw portion 36 is completely narrowed and closed. When the claw portion 36 is sandwiched and closed, the claw of the claw portion 36 holds the shoulder portion 44 of the syringe 21 firmly.

  In this state, the plunger 52 engages with the lower engagement groove 53. Therefore, the syringe 21 can be rotated in this state.

  When the syringe 21 is rotated at a high speed, the mechanical force due to the contact is not applied to the rubber stopper 41 at all. Also by such 2nd Embodiment, there can exist an effect similar to embodiment mentioned above.

(Third embodiment)
FIG. 7 is a cross-sectional view showing a holding device 20 according to the third embodiment of the present invention. The third embodiment is similar to the first embodiment, and FIG. 7 corresponds to FIG. 4 of the first embodiment.

In the case of the third embodiment, there is no step between the rubber stopper 41 attached to the tip of the syringe 21 and the syringe 21, and the syringe 21 should be pressed by the claw portion 36 as shown in FIG. There is no shoulder 44.

  In the third embodiment, a claw mechanism 34 shown in FIG. 8 is used. As shown in FIG. 7, the claw mechanism 34 includes a cylindrical portion 61 that extends in the axial direction of the syringe 21, that is, downward. The cylindrical portion 61 does not protrude outward in the radial direction from the claw portion 36 and is accommodated in the outer case 31 without any obstacle when the outer case 31 is lowered. The tubular portion 61 is formed with a rectangular through hole 62 through which the claw can pass at a location corresponding to the claw of the claw portion 36.

  FIG. 7A shows a state before the claw mechanism 34 is lowered, and the claw portion 36 protrudes outward from the opening portion 33 in a state of passing through the through hole 62 radially outward. .

  And the nail | claw part 36 has spread in the side of the syringe 21, ie, the radial direction, in this protruding state. The cylindrical part 61 faces the syringe 21 and is in an acceptable state.

  FIG. 7B shows a state in which the holding body 22 and the grip portion 23 are lowered as shown by arrows in accordance with the traveling state of the roller 13 (see FIG. 1) on the cam rail 12. Since the cylindrical part 61 is integrally formed with the claw mechanism 34, the cylindrical part 61 is lowered with the lowering operation of the claw mechanism 34, and the syringe 21 is accommodated therein.

  When the lower end of the cylindrical portion 61 comes into contact with the flange 42 formed at the proximal end of the syringe 21, the downward movement of the cylindrical portion 61 stops. Thus, the cylindrical part 61 is covered from the upper side of the syringe 21 and presses the flange 42. The claw holding rod 37 does not contact the rubber stopper 41.

  FIG. 7C shows a state in which the outer case 31 is lowered by further lowering the holding body 22 after the cylindrical portion 61 comes into contact with the flange 42.

  As the outer case 31 descends, the opened claw portion 36 is tightened from the outside by the inner surface of the outer case 31 and gradually narrowed, passing through the through hole 62 radially inward and closing. And the nail | claw part 36 is narrowed and closes completely. When the claw portion 36 is sandwiched and closed, the claw of the claw portion 36 holds the contact portion of the barrel of the syringe 21.

Therefore, since the syringe 21 is held by the cylindrical portion 61 and the claw portion 36, the syringe 21 is sufficiently secured even when the shoulder portion 44 as shown in FIG. 4 is not formed on the syringe 21. Will be retained.

  In this state, when the syringe 21 is rotated at a high speed, the rubber plug 41 is not subjected to any mechanical force due to contact. Also according to the third embodiment, it is possible to achieve the same operational effects as the above-described embodiment.

(Fourth embodiment)
FIG. 9 is a cross-sectional view showing a holding device 20 according to the fourth embodiment of the present invention. The fourth embodiment is similar to the third embodiment shown in FIGS.

In the case of the fourth embodiment, as in the third embodiment, there is no step between the rubber stopper 41 attached to the tip of the syringe 21 and the syringe 21, and the syringe 21 is as shown in FIG. There is no shoulder 44 to be pressed by the claw 36.

  In the third embodiment shown in FIG. 7, the flange 42 is configured to be pressed and pressed toward the pedestal 14 by the cylindrical portion 61, but in the case of the fourth embodiment, as shown in FIG. The flange 42 is clamped and supported by the combination of the two bases.

  As shown in FIG. 10, the holding device 20 includes an upper base 71 as an upper support part on the upper side of the base 14 as a support part. The pedestal 14 and the upper pedestal 71 can move toward and away from each other, and are configured as a set. The upper pedestal 71 is formed with a cut portion 72 on the side, and the barrel portion of the syringe 21 can be inserted into the cut portion 72 from the side in the horizontal direction as indicated by an arrow.

  FIG. 9A shows a state before the claw mechanism 34 is lowered, and the claw portion 36 protrudes outward from the opening 33. And the nail | claw part 36 has spread in the side of the syringe 21, ie, the radial direction, in this protruding state.

  At this time, the body portion of the syringe 21 passes through the cut portion 72 of the upper pedestal 71 as shown in FIG. 10, and the syringe 21 is placed on the pedestal 14. In addition, after the syringe 21 is mounted on the base 14, it is also possible to comprise so that the upper base 71 may be moved from the side to the upper side of the base 14.

  FIG. 9B shows a state where the outer case 31 is lowered and the rubber plug 41 is stored in the space 46 formed by the claw 36. In this state, the claw mechanism 34 does not contact the rubber stopper 41. The outer case 31 is separated from the holding body 22 and is driven by a drive mechanism that can move the outer case 31 downward.

  FIG. 9C shows a state where the outer case 31 is further lowered. In this state, when the outer case 31 is lowered, the opened claw portion 36 is tightened by the inner surface of the outer case 31 from the outside, gradually narrowed, and closed. And the nail | claw part 36 is narrowed and closes completely. When the claw portion 36 is sandwiched and closed, the claw of the claw portion 36 holds the contact portion of the barrel of the syringe 21.

  FIG. 9D shows a state where the pedestal 14 is then moved upward as indicated by an arrow, and the flange 42 is sandwiched and pressed between the pedestal 14 and the upper pedestal 71 and supported. Note that the upper pedestal 71 may be moved downward so that the flange 42 is sandwiched between the pedestal 14 and the upper pedestal 71.

  Accordingly, the syringe 21 is supported by being sandwiched and pressed by the nail portion 36 of the body portion and the flange 42 by the set of the base 14 and the upper base 71. For this reason, even when the shoulder part 44 as shown in FIG. 4 is not formed in the syringe 21, the syringe 21 is held sufficiently firmly.
