At this moment, for example medical fluid injector 200 is connected to the retainer parts 340 of pipe connection 300, this medical fluid injector 200 is loaded in the injection Executive Head 110 of liquid injection device 100 by feed tube for liquid 120.Like this, the cartridge unit 210 of medical fluid injector 200 is maintained in the maintaining body 115, and keep piston element 220 by piston drive mechanism 116, therefore, liquid injection device 100 becomes the state in the cartridge unit 210 that piston element 220 can be pressed into medical fluid injector 200.

But, because liquid injection device 100 is controlled to be akinesia with piston drive mechanism 116 under original state, so piston drive mechanism 116 can unexpectedly not worked.In addition, when feed tube for liquid 120 is connected to the retainer parts 340 of pipe connection 300, for example, on retainer parts 340, also be connected with injecting liquid drug pipe 130 as mentioned above.

In addition, shown in Fig. 1 and Fig. 6 (a), pipe connection 300 is in keeping out of the way under the state as original state, container maintaining body 315, curtain-shaped cover member 335, weak point/minute hand parts 341,342 are disposed at retreating position, do not produce the front end of interference so container maintaining body 315 is configured in curtain-shaped cover member 335 with weak point/minute hand parts 341,342.

Then, the operator takes off protective cover 412 from the protective cover 411 of medical liquid container 400, and is loaded into the container maintaining body 315 from the top with this medical liquid container 400.Under such state, when the guidance panel 103 to liquid injection device 100 carried out the input operation of " connecting beginning ", the data of being imported just sent to pipe connection 300 from liquid injection device 100.

Like this, in this pipe connection 300, shown in Fig. 6 (b), at first medical liquid container 400 is moved to the perforation position of rear end from the retreating position of front end by container travel mechanism 310, then shown in Fig. 6 (c), curtain-shaped cover member 335 is moved to the perforation position of lower end from the retreating position of upper end by covering travel mechanism 330.Like this, cover the opening of medical liquid container 400, and keep medical liquid container 400 from the top by curtain-shaped cover member 335.

Next, shown in Fig. 6 (d), since by retainer travel mechanism 320 will lack/minute hand parts 341,342 retreating positions from the upper end move to the perforation position of lower end, so weak point/minute hand parts 341,342 pierce through the elastomeric element 402 of medical liquid container 400 from the through hole 336 of curtain-shaped cover member 335.Like this, the far-end of hour hand parts 341 is located in the inner and upper of medical liquid container 400, and minute hand parts 342 are located in inner below.

Then, pipe connection 300 returns the data of " connection is finished " to liquid injection device 100, so in this liquid injection device 100, in the liquid crystal display 104 of injection control unit 101, show and output " be connected and finish ", thereby akinesia of releasing piston drive mechanism 116.

Under such state, when for example the guidance panel 103 to liquid injection device 100 carries out the input operation of " warming up execution ", only piston drive mechanism 116 is driven the scheduled time.Then, supply with the normal saline of predetermined volumes from this medical fluid injector 200 to medical liquid container 400, so inject and fill the contrast agent of predetermined volumes to injecting liquid drug pipe 130 from airtight medical liquid container 400 by feed tube for liquid 120.

Behind such inside and deaeration, the far-end of this injecting liquid drug pipe 130 is connected with subject's blood vessel with normal saline and contrast agent filling liquid supply/injecting liquid drug pipe 120,130.Under such state, for example if guidance panel 103 is carried out the input operation of " action of injection execution ", then for example driven plunger driving mechanism 116 detects the injection end until emptying pick off 118, therefore, the normal saline of medical fluid injector 200 supplies to medical liquid container 400 by feed tube for liquid 120.

At this moment, because the proportion of normal saline is littler than contrast agent, so become below the inside of medical liquid container 400 contrast agent is positioned at and the state of normal saline above being positioned at, therefore, contrast agent is injected to the subject by injecting liquid drug pipe 130 from the minute hand parts 342 that far-end is positioned at the below, inside of medical liquid container 400.

And, in the liquid injection device 100 of present embodiment, owing to suitably adjust the capacity of medical fluid injector 200 and medical liquid container 400, therefore, after whole contrast agent are expelled to the subject from medical liquid container 400, will be expelled to the subject from the normal saline that medical fluid injector 200 is sent to medical liquid container 400.

Here owing to be to promote contrast agent by normal saline from the rear, so contrast agent can arrive subject's the shooting position of being made a video recording by PET device 500.Arrived the contrast agent at shooting position like this, although absorbed better than " normal cell " by so-called " cancerous cell ", this absorption needs the scheduled time.

Therefore, when by emptying pick off 118 detecting contrast-medium injection end, then measure as mentioned above by the scheduled time of pair cell absorption contrast agent for the liquid injection device 100 of present embodiment.Then, passed through should the time time when detecting this, sent it to PET device 500, therefore, this PET device 500 has been passed through should the time time when receiving from liquid injection device 100, then by 501 couples of subjects of perspective image unit fluoroscopy images of making a video recording.

In addition, when PET device 500 is finished the shooting of fluoroscopy images, send it to liquid injection device 100, therefore, the liquid injection device 100 that has received this " shooting is finished " sends " connect and remove " to pipe connection 300.At this moment, in receiving the pipe connection 300 of " connect remove ", shown in Fig. 6 (c), by retainer travel mechanism 320 will lack/minute hand parts 341,342 perforation position from the lower end move to the retreating position of upper end.

And, shown in Fig. 6 (b), by covering travel mechanism 330 moves to curtain-shaped cover member 335 upper end from the perforation position of lower end retreating position; Shown in Fig. 1 and Fig. 6 (a), medical liquid container 400 is moved to the retreating position of front end by container travel mechanism 310 from the perforation position of rear end.Then, the operator takes out medical liquid container 400 from container maintaining body 315, for example takes out and discarded container body 401 from its protective cover 411, and protective cover 411 and protective cover 412 can reuse.

The effect of embodiment

In the penetrating and shooting system 1000 of present embodiment, utilize piston drive mechanism 116 that the normal saline of medical fluid injector 200 is pressed into the medical liquid container 400 from feed tube for liquid 120, contrast agent with this medical liquid container 400 is expelled to the subject from injecting liquid drug pipe 130 thus, so, contrast agent directly can be expelled to the subject from medical liquid container 400 and not need medical fluid injector through filling formula again etc.Therefore, because the operator do not need to fill contrast agent or operate this medical fluid injector to medical fluid injector from medical liquid container 400, so even contrast agent has radioactivity also can reduce radiation to the operator well.

And, owing to make weak point/minute hand parts 341,342 pierce through the elastomeric element 402 of medical liquid container 400, pierce through so need not carry out this by manual working by the operator by pipe connection 300.And,, before finishing, do not need to operate medical liquid container 400 later on, so can reduce radiation well to the operator to injection if the operator will be filled to pipe connection 300 from the medical liquid container 400 that protective cover 411 has taken off protective cover 412.

And, under original state, be configured in the retreating position that curtain-shaped cover member 335 grades do not produce the front end of interference owing to be filled with the container maintaining body 315 of medical liquid container 400, so the operator can promptly be filled to pipe connection 300 with medical liquid container 400.Therefore the time that the operator operates the medical liquid container 400 of the radiation lonizing radiation that taken off protective cover 412 can be shortened, thereby radiation can be reduced better the operator.

And, because the pipe connection 300 of present embodiment at first seals the opening of the medical liquid container 400 that is loaded by curtain-shaped cover member 335, so can further shorten the operator by radiated time, thereby can prevent the operator the injection operation implementation in by radiation.And, owing to pass through the injection control unit 101 operated from a distance pipe connections 300 of liquid injection device 100,, thereby can further reduce radiation to the operator so the operator does not need manual operation to load the pipe connection 300 of medical liquid container 400.

In addition, in the pipe connection 300 of present embodiment, seal the opening of medical liquid container 400, and keep medical liquid container 400 from the top by curtain-shaped cover member 335.Therefore, can make weak point/minute hand parts 341,342 stably pierce through the elastomeric element 402 of medical liquid container 400, can prevent that also the elastomeric element 402 that the pressure owing to the normal saline of being injected causes from coming off from medical liquid container 400.

And, because weak point/minute hand parts 341,342 pierce through elastomeric element 402 from the through hole 336 of the minor diameter of curtain-shaped cover member 335, so can guide weak point/minute hand parts 341,342 by this through hole 336, thereby can make weak point/minute hand parts 341,342 more stably pierce through elastomeric element 402.

And in the pipe connection 300 of present embodiment, container travel mechanism 310 moves horizontally medical liquid container 400, retainer travel mechanism 320 with cover travel mechanism 330 and make weak point/minute hand parts 341,342 and curtain-shaped cover member 335 vertical moving.Therefore, the action of various travel mechanisms 310,320,330 is single, and this simple in structure and durability and reliability are good.

In addition, owing to as mentioned above moving horizontally with vertical the moving of weak point/minute hand parts 341,342 and curtain-shaped cover member 335 of medical liquid container 400 combined, therefore can make moving range separately be minimum, pipe connection 300 can be realized whole miniaturization and.But especially because retainer travel mechanism 320 and cover travel mechanism's 330 common guide rails etc., so the realization miniaturization and that can further simplify the internal structure of an organization.

And in the pipe connection 300 of present embodiment, can automatically produce following state successively: medical liquid container 400, curtain-shaped cover member 335 and weak point/minute hand parts 341,342 are configured in the state of keeping out of the way of retreating position; Medical liquid container 400 is configured to the SBR that perforation position and curtain-shaped cover member 335 and weak point/minute hand parts 341,342 are configured in retreating position; Medical liquid container 400 and curtain-shaped cover member 335 are configured in the shielding status that perforation position and weak point/minute hand parts 341,342 are configured in retreating position; And medical liquid container 400, curtain-shaped cover member 335 and weak point/minute hand parts 341,342 are configured in perforation position and pierce through state.

Therefore, the operator does not need various travel mechanisms 310,320,330 are individually carried out manual operation, just can make weak point/minute hand parts 341,342 pierce through the elastomeric element 402 of medical liquid container 400 exactly.And, because the pipe connection 300 of present embodiment can produce above-mentioned various states round about successively, therefore can be simply and promptly take out the medical liquid container 400 of having finished the injection operation.

In addition, because medium that contrast agent is pressurizeed is made of normal saline, so even can also no problem medium comes contrast agent is pressurizeed by being expelled to the subject.And, because the proportion of contrast agent is fully greater than the proportion of normal saline, the far-end of feed tube for liquid 120 is configured in the inner and upper of medical liquid container 400, and the cardinal extremity of injecting liquid drug pipe 130 is configured in the inside below of medical liquid container 400, so can easily carry out at first the only operation of injection of contrast medium and then injecting normal saline to the subject.

In addition, owing to keep the weak point/minute hand parts 341,342 of liquid supply/injecting liquid drug pipe 120,130 integratedly by retainer parts 340, so can more easily liquid supply/injecting liquid drug pipe 120,130 be connected with medical liquid container 400, can will lack easy and exactly/far-end of minute hand parts 341,342 is configured to the appropriate location of medical liquid container 400 inside.

And weak point/minute hand parts 341,342 and retainer parts 340 form as one, and these retainer parts 340 can be installed in the retainer travel mechanism 320 with freely loading and unloading.Therefore, retainer parts 340 and weak point/minute hand parts 341,342 that replacing easily and normal saline contact with contrast agent, thus can keep pipe connection 300 to clean all the time and do not need special cleaning etc.

And in the penetrating and shooting system 1000 of present embodiment, pipe connection 300 and liquid injection device 100 splits form, as long as liquid injection device 100 can be exactly passable to pipe connection 300 force feed normal saline.Therefore, existing goods can be utilized as liquid injection device 100, thereby can easily construct the penetrating and shooting system 1000 of present embodiment.

In addition, in the penetrating and shooting system 1000 of present embodiment, since have only when pipe connection 300 when piercing through state, liquid injection device 100 makes the state of piston drive mechanism 116 for working, so liquid supply/injecting liquid drug pipe 120,130 be not connected under the state of medical liquid container 400, medical fluid injector 200 can not be driven.

And in the penetrating and shooting system 1000 of present embodiment, when liquid injection device 100 detects when injection finishes to begin to have passed through the scheduled time, PET device 500 begins image taking automatically.Therefore, although before the optimum state that becomes the shooting that is suitable for fluoroscopy images, also need preset time, because therefore the process that automatic gauge should the time can take fluoroscopy images at optimum state even PET is expelled to the subject with contrast agent.

The variation of embodiment

The present invention is not limited to present embodiment, can carry out various deformation in the scope that does not break away from its invention thought.For example, example illustrates liquid injection device 100 and pipe connection 300 splits and forms in the above-described embodiment, but the liquid injection device (not shown) that both are integrated etc. also can be implemented.

In addition, in the above-described embodiment illustration the container travel mechanism 310 of pipe connection 300 by means of the driving force of travel mechanism's motor 311 medical liquid container 400 is moved horizontally with container maintaining body 315, but for example also can be the container travel mechanism (not shown) that does not have drive source by operator's manual operation, make medical liquid container 400 move horizontally (not shown) thus with container maintaining body 315.

In this case, although the amount of radiation of comparing the operator with above-mentioned pipe connection 300 increases, but can radiate lonizing radiation upward owing to be contemplated to the medical liquid container 400 that has taken off protective cover 412, therefore, if for example in the place ahead of container maintaining body 315 or side etc. form manually operated operating portion, just the radiation to the operator can be reduced to Min., can medical liquid container 400 be moved horizontally by manual operation simultaneously.

In addition, even in the pipe connection (not shown) that medical liquid container 400 is moved horizontally, preferably also be: install in its container travel mechanism and keep out of the way/perforation position pick off 312,313, when medical liquid container 400 is configured in retreating position, with retainer travel mechanism 320 with cover travel mechanism 330 and force to be configured to retreating position, only when medical liquid container 400 is configured in perforation position for making retainer travel mechanism 320 and covering the state that travel mechanism 330 moves.

And, in the pipe connection that medical liquid container 400 is moved horizontally, for example preferably:, medical liquid container 400 is remained on perforation position and retreating position by protuberance that makes container maintaining body 315 and the structure (not shown) that the recess of container travel mechanism engages.

In addition, although in the above-described embodiment illustration pipe connection 300 cover the example of the opening of medical liquid container 400 by curtain-shaped cover member 335, also can not have such curtain-shaped cover member 335.In addition, although example illustrates curtain-shaped cover member 335 and is tungsten system in the above-described embodiment, it also can be for lead system etc., and container maintaining body 315 also can be by tungsten or plumbous formation.

And, in the above-described embodiment illustration the situation that travel mechanism 330 moves curtain-shaped cover member 335 of covering by special use, but for example also can be that curtain-shaped cover member 335 is fixed in from the opposed position of the opening (not shown) of the medical liquid container 400 of top and perforation position, can also be that pipe connection 600 is such as illustrated in Figure 7, make curtain-shaped cover member 335 and retainer parts 340 integrally formed

(not shown).

At this moment, owing to lacking/minute hand parts 341,342 pierce through the opening that does not cover medical liquid container 400 before the medical liquid container 400 by curtain-shaped cover member 335, although so being increased of subject by radiated time, but owing to do not need the special-purpose travel mechanism 330 of covering, therefore, can make the designs simplification of pipe connection.

In addition, example illustrates and can carry out operated from a distance to pipe connection 300 by the manual operation of liquid injection device 100 in the above-described embodiment, but for example also can be that special-purpose guidance panel (not shown) is installed in pipe connection 300.In addition, as mentioned above pipe connection 300 is being carried out under the remote-operated situation, easy and confirm promptly whether this weak point/minute hand parts 341,342 have suitably pierced through elastomeric element 402 and be not the comparison difficulty by radiation.

Therefore, when this situation becomes problem, preferably: pipe connection 700 is such as illustrated in Figure 8, and (Charge CoupledDevice: charge coupled device) photographing unit 710 is as piercing through camera head for example to locate to install CCD at the front surface of retainer parts 340 etc.In this case, owing to can take, therefore can in liquid crystal display 104 grades of liquid injection device 100, show and export this photographic images by the position that 710 pairs of weak points of CCD photographing unit/minute hand parts 341,342 pierce through elastomeric element 402.

Like this, the guidance panel 103 by manual operation liquid injection device 100 make pipe connection 700 will lack/when minute hand parts 341,342 pierce through elastomeric element 402, can in the liquid crystal display 104 that is set up in parallel with this guidance panel 103, show and state is pierced through in output, therefore, the operator can be easy and be confirmed in real time whether weak point/minute hand parts 341,342 suitably pierce through elastomeric element 402 and can be by radiation.

In addition, example is illustrated in liquid supply/injecting liquid drug pipe 120,130 and medical fluid injector 200 with after medical liquid container 400 is connected in the above-described embodiment, fill the inside of this liquid supply/injecting liquid drug pipe 120,130 with contrast agent and normal saline and come deaeration, but for example also can be before being connected to medical fluid injector 200 and medical liquid container 400 with the inside of filling liquid supply/injecting liquid drug pipes 120,130 such as normal saline.

In addition, only example illustrates by the bubble output mechanism and discharges the bubble of sneaking in the contrast agent in the above-described embodiment, but for example also can be to locate to dispose bubble detecting sensor (not shown) in the position in the downstream of this bubble output mechanism etc., when detecting bubble, force to stop piston drive mechanism 116, or block medicinal liquid syringe 130 by the injection shut-off mechanism (not shown) of special use by this bubble detecting sensor.

Can in injecting liquid drug pipe 130, install in addition by there being no radiation to come the detection of radioactive contrast agent to switch to the change detection pick off (not shown) of normal saline, force to stop piston drive mechanism 116 when switching when in this injecting liquid drug pipe 130, detecting.

In the liquid injection device 100 of above-mentioned embodiment,, therefore be difficult to confirm exactly whether the contrast agent of medical liquid container 400 all is expelled to the subject owing to be expelled to the subject by the contrast agent of normal saline pushing medical liquid container 400.But, if coming that by the change detection pick off mobile contrast agent in injecting liquid drug pipe 130 is switched to normal saline as mentioned above detects, whether the contrast agent that then can confirm medical liquid container 400 easy and reliably all is expelled to the subject, thereby can piston drive mechanism 116 be stopped.

In addition, also can by the change detection sensor when mobile contrast agent has switched to normal saline in injecting liquid drug pipe 130, continue the force feed normal saline and after predetermined volumes, stop.In this case, owing to after contrast agent, injected the normal saline of predetermined volumes to the subject, so can make contrast agent arrive subject's shooting position exactly by normal saline.

In addition, in the above-described embodiment by suitably adjusting the capacity of medical fluid injector 200 and medical liquid container 400, suppose that the whole normal saline by liquid medicine injection syringe 200 make contrast agent positively arrive subject's shooting position, but for example also can be that the capacity from the normal saline of medical fluid injector 200 injection is controlled so that can be to the excessive or insufficient contrast agent of shooting position injection.

In this case, for example preferably: in the computer unit 140 of the injection control unit 101 of liquid injection device 100, liquid capacity is carried out the data registration according to the shooting position, when importing subjects' image pickup part bit data, come the capacity of injecting normal saline is controlled according to this shooting position by guidance panel 103.

In addition, example illustrates 100 pairs of contrast agent of being injected of liquid injection device and is measured by the scheduled time that cell absorbs in the above-described embodiment, and carry out data notification to PET device 500, but for example also can be liquid injection device 100 is injected end immediately to PET device 500 data notification, begin to measure the process of the scheduled time by this PET device 500 from finishing injection, thereby begin the shooting action automatically.

In addition, example illustrates by piston drive mechanism 116 and by feed tube for liquid 120 normal saline is sent to medical liquid container 400 from medical fluid injector 200 in the above-described embodiment, thereby by injecting liquid drug pipe 130 contrast agent is sent to the subject from this medical liquid container 400.But, when worrying only to rely on such force feed normal saline that utilizes piston drive mechanism 116 or contrast agent to produce adverse current, for example can insert the check valve that the flow direction of normal saline is restricted to a direction, or insert the check valve that the flow direction of contrast agent is restricted to a direction at injecting liquid drug pipe 130 at feed tube for liquid 120.

In addition, example illustrates the cartridge unit of liquid injection device 100 by piston element being pressed into the medical fluid injector that is filled with normal saline, normal saline is pressed into the feed tube for liquid 120 that is connected with this medical fluid injector in the above-described embodiment, but also can refer to mechanism or rotary pump mechanism etc. by making liquid injection device have wriggling, push feed tube for liquid 120 that is connected with liquid container etc. from the outside successively, come force feed normal saline (not shown).

In addition, in the above-described embodiment for convenience of explanation, the formation of pipe connection 300 grades schematic diagram and explanation have been carried out.But because the actual pipe connection that had a fling at of the present application people, therefore below in Fig. 8 and Fig. 9 illustration this pipe connection that has a fling at 800, and carry out briefly bright.

The structure of this pipe connection 800 and above-mentioned pipe connection 700 are roughly the same, and it has: connecting device main body 301, container travel mechanism 310, container maintaining body 315, retainer travel mechanism 320, cover travel mechanism 330, curtain-shaped cover member 335, retainer parts 340, weak point/minute hand parts 341,342 and CCD photographing unit 710 etc.

But in this pipe connection 800, CCD photographing unit 710 is installed on connecting device main body 301, for example, and by the state of axle supporting for direction revolution to the left and right.In addition, also have additional guidance panel 810 at the upper surface left of connecting device main body 301, the manual operation by this guidance panel 810 also can be to from keeping out of the way state to piercing through moving and controlling to the action that moves forward into of keeping out of the way state from piercing through state of state.And, as shown in figure 10, retainer parts 340 and weak point/minute hand parts 341,342 are required minimal cellular construction, and as shown in Figure 9, weak point/minute hand parts 341,342 can be installed on retainer travel mechanism 320 with retainer parts 340 with freely loading and unloading.

Then, carry out briefly bright below with reference to Figure 11 to Figure 14 to second pipe connection 900 that has a fling at.As shown in figure 11, this pipe connection 900 forms the structure roughly the same with above-mentioned pipe connection 800, but as shown in figure 12, container travel mechanism 910 is made of pair of guide rails 911, as shown in figure 13, travel mechanism's motor 311 drive sources such as grade are not installed.

Therefore, container maintaining body 920 is equipped with the mobile guiding of being controlled by finger integratedly at left end and handles knob 921, and container maintaining body 920 handle knob 921 together by manually moving forward and backward with moving to guide.This container maintaining body 920 is formed with recess 922 at the lower surface of left end, form a pair of configuration locking mechanism 923,924 by engaging pawl or wind spring etc., this configuration locking mechanism 923,924 is locked in retreating position and perforation position by engaging with these recess 922 elasticity with container maintaining body 920.

Mobile guiding is handled knob and 921 is formed the crank-like that is communicated with to left, below, left successively from container maintaining body 920, and latch-release is handled knob and 925 is assembled in and moves handle knob 921 vertical component of guiding, and is free to slide on can be along the vertical direction.This latch-release handle knob 925 by wind spring (not shown) etc. by elastic force-applying upward, form outstanding protuberance 926 at its right-hand member downwards as latch-release mechanism.

Therefore, move guiding and handle knob 921 the time when controlling, latch-release is handled knob and 925 is also controlled together and displacement downwards.At this moment, owing to push latch-release is handled knob configuration locking mechanism 923,924 that 925 protuberance 926 engages with the recess 922 of container maintaining body 920 downwards, the locking by 923,924 pairs of container maintaining bodies 920 of configuration locking mechanism just is disengaged.

In addition, container maintaining body 920 has formed flat protuberance 928 at right-hand member, by a pair of optical sensor that this protuberance 928 is carried out optical detection, formed at retreating position and perforation position and detected keeping out of the way/perforation position pick off 312,313 of container maintaining body 920.Container maintaining body 920 utilizes the through hole 929 at the above-below direction opening to keep medical liquid container 400, but from below the position dispensing containers elevating mechanism 930 relative with the through hole 929 of the container maintaining body 920 that is in retreating position.

Shown in Figure 12 to 14, this container elevating mechanism 930 has the discoid maintenance platform 931 that keeps medical liquid container 400 from the below, and this maintenance platform 931 is supported to and can be moved freely along the vertical direction by guide shaft (guide shaft) 932 grades.And, owing to, therefore keep platform 931 to move up and down by means of the driving force of this elevating mechanism motor 933 keeping on the platform 931 being connected with elevating mechanism motor 933 by thread mechanism (not shown) etc.

This container elevating mechanism 930, move up and down by pushing the medical liquid container 400 the through hole 929 that is configured in the container maintaining body 920 that is in retreating position with the maintenance platform 931 that moves up and down from the below, make the loading position of the medical liquid container 400 that is in retreating position above being positioned to the holding position that remains on the container maintaining body 920 that is in retreating position with than this holding position.

Therefore, for example utilize optical sensor (not shown) etc., on container elevating mechanism 930, install medical liquid container 400 is configured in the loading position pick off 935 that detects the loading position and medical liquid container 400 is configured in the holding position pick off 936 that detects the holding position keeping platform 931 to carry out optical detection.

In addition, this pipe connection 900 also has curtain-shaped cover member 335, but this curtain-shaped cover member 335 is fixed on from top and the medical liquid container 400 opposed positions that are disposed at perforation position.In addition, also be formed with guidance panel 941 at the front end upper surface of connecting device main body 301, this guidance panel 941 also is connected with control circuit 940 as motion control device.

This control circuit 940 according to the input operation of guidance panel 941, keep out of the way/testing result of perforation position pick off 312,313 etc., come control is moved by container elevating mechanism 930 and retainer travel mechanism 320.Therefore, only when medical liquid container 400 was configured in retreating position, for making the state of container elevating mechanism 930 work, when medical liquid container 400 was not configured in retreating position, container elevating mechanism 930 was for being in the state of holding position.In addition, only when medical liquid container 400 was configured in perforation position, for making the state of retainer travel mechanism 320 work, when medical liquid container 400 was not configured in perforation position, retainer travel mechanism 320 was for being in the state of retreating position.

Shown in Figure 14 (a), the pipe connection 900 of structure is under original state as mentioned above, container maintaining body 920 is configured in retreating position by manual operation, and container elevating mechanism 930 is by being configured in the loading position of top because of the action control that is in the caused control circuit 940 of original state.

Therefore, when inserting medical liquid container 400 from the through hole 929 of last direction container maintaining body 920, this medical liquid container 400 is maintained at the loading position by mounting in container elevating mechanism 930.At this moment, because container maintaining body 920 is locked in retreating position by configuration locking mechanism 923, therefore under the state that container maintaining body 920 has been shifted from retreating position, uneasy medicine liquid holding containers 400.

In addition, when container maintaining body 920 suitably was configured in retreating position like this, by recording this situation by retreating position pick off 312, container elevating mechanism 930 became the state that can work.Therefore, when the operator when guidance panel 941 carries out input operation that container descends, medical liquid container 400 and container elevating mechanism 930 drop to the holding position from the loading position together, therefore, shown in Figure 14 (b), this moment, medical liquid container 400 remained on the container maintaining body 920 that is in retreating position.

About medical liquid container 400, come wrapping container main body 401 in order to cut off lonizing radiation with heavy-walled plumbous system protective cover 411 and protective cover 412 as mentioned above, so medical liquid container 400 weight may be heavier, but in this pipe connection 900, make medical liquid container 400 drop to the holding position of container maintaining body 920 reposefully by container elevating mechanism 930 as mentioned above, therefore do not need to make medical liquid container 400 to fall to making itself and 920 collisions of container maintaining body to keep.

In addition, as mentioned above, container maintaining body 920 is locked in retreating position by configuration locking mechanism 923 under original state, when container elevating mechanism 930 when retreating position is shifted is not worked, therefore, under the state that container maintaining body 920 has been shifted from retreating position, medical liquid container 400 can mounting and is dropped on the container elevating mechanism 930, and medical liquid container 400 suitably remained in container maintaining body 920.

When this maintenance is finished, for example the operator from medical liquid container 400 manually take off protective cover 412, the mobile guiding of controlling container maintaining body 920 together with finger handles knob and 921 handles knob 925 with latch-release.So, handles knob and 925 descend because this controls latch-release, thereby removed the locking of 923 pairs of container maintaining bodies 920 of configuration locking mechanism, so this container maintaining body 920 can move freely.

Therefore, 921 retreat by handling knob with the mobile guiding that manually makes the operator and controlled, shown in Figure 14 (c), container maintaining body 920 slides from retreating position and moves to perforation position.At this moment, owing to retreating position pick off 312 detects less than container maintaining body 920, so container elevating mechanism 930 is fixed on the holding position and can not works.

Then, when container maintaining body 920 moved to perforation position, this container maintaining body 920 was configured locking mechanism 924 locking, and was pierced position sensor 313 and detects.Be configured in perforation position and be pierced before position sensor 313 detects at container maintaining body 920 like this, retainer travel mechanism 320 is configured in the top retreating position, when container maintaining body 920 is configured in perforation position and is pierced position sensor 313 when detecting, retainer travel mechanism 320 becomes the state that can work.

Therefore, when by the operator guidance panel 941 being pierced through the input operation of beginning, shown in Figure 14 (d), weak point/minute hand parts 341,342 drop to perforation position and are connected with medical liquid container 400 from retreating position by retainer travel mechanism 320.At this moment, being configured locking mechanism 924 at aforesaid container maintaining body 920 is locked in perforation position and is pierced under the position sensor 313 detected states, weak point/minute hand parts 341,342 pierce through, therefore medical liquid container 400 from pierce through displacement state under, weak point/minute hand parts 341,342 can not pierce through.

As mentioned above, when weak point/minute hand parts 341,342 pierced through medical liquid container 400 by retainer travel mechanism 320, this situation was sent to liquid injection device 100 from pipe connection 900, therefore carries out injecting liquid drug by this liquid injection device 100.When this injecting liquid drug is finished, for example by guidance panel 941 being pierced through the input operation of releasing by the operator, shown in Figure 14 (c), weak point/minute hand parts 341,342 rise to retreating position and break away from from medical liquid container 400 from perforation position by retainer travel mechanism 320.

Under such state, the mobile guiding of controlling container maintaining body 920 together with finger as the operator is handled knob and 921 is handled knob 925 the time with latch-release, and the locking that configuration locking mechanism 924 applies is disengaged, and container maintaining body 920 can move freely.Thus, 921 advance by handling knob with the mobile guiding that manually makes the operator and controlled, shown in Figure 14 (b), container maintaining body 920 slides from perforation position and moves to retreating position.

Then, the container maintaining body 920 that moves to retreating position is locked by configuration lock mechanism 923, and is detected by retreating position pick off 312.So, become workable state according to this detection container elevating mechanism 930, therefore for example when the operator carries out the input operation of container rising to guidance panel 941, shown in Figure 14 (a), the medical liquid container 400 that is in retreating position rises by container elevating mechanism 930.So far, because medical liquid container 400 rises to the loading position from the holding position of container maintaining body 920, therefore can easily take out the bigger medical liquid container of weight 400.

In above-mentioned pipe connection 900, container elevating mechanism 930 moves up and down medical liquid container 400 at retreating position as mentioned above, therefore can load and unload medical liquid container 400 simply.And, by configuration locking mechanism 923,924 container maintaining body 920 is locked in retreating position and perforation position, therefore under the state that container maintaining body 920 has been shifted from retreating position, uneasy medicine liquid holding containers 400, medical liquid container 400 from pierce through displacement state under, weak point/minute hand parts 341,342 do not pierce through.

In addition, handle knob when controlling latch-release that above-mentioned configuration locking mechanism 923,924 is disengaged 925 the time, since this latch-release handle knob 925 and the mobile guiding of manually moving that is used for container maintaining body 920 handle knob and 921 controlled together, therefore can carry out the operation that the locking of removing container maintaining body 920 moves it easily.

And, container elevating mechanism 930 is the state for working when container maintaining body 920 is disposed at retreating position only, therefore container elevating mechanism 930 can not worked under unsuitable state, when container maintaining body 920 is not configured in retreating position, container elevating mechanism 930 is configured in the holding position, and therefore the medical liquid container 400 that moves forward and backward with container maintaining body 920 can not collide with container elevating mechanism 930 yet.

Similarly, retainer travel mechanism 320 is the state for working when container maintaining body 920 is disposed at perforation position only, therefore retainer travel mechanism 320 can not work under unsuitable state, when container maintaining body 920 is not configured in perforation position, when retainer travel mechanism 320 is configured in retreating position, so and the medical liquid container 400 that moves forward and backward together of container maintaining body 920 also can with weak point/minute hand parts 341,342 collisions.

In addition, in the above-described embodiment illustration the medical liquid container 400 of given size directly is installed to the situation of the container maintaining body 315 of pipe connection 300, but for example also pipe connection 950 is such as illustrated in Figure 15, the medical liquid container 400 of given size directly is installed on container maintaining body 920, and the container adapter 951 by special use will be installed on container maintaining body 920 smaller or equal to the medical liquid container 420 of given size.

And then, as illustrated in Figure 16 shown in the pipe connection 960, can also be that medical liquid container 400,420 by various sizes forms container maintaining body 920,961, such container maintaining body 920,961 also can be loaded in the container travel mechanism 910 with freely loading and unloading.
