Portion, it controls above-mentioned drive division.
In addition, it is boxlike device for introducing media according to the device for introducing media 10 of the present embodiment, it is being stored in drug cassette 100
Medicine use up completely in the case of, reinstall new drug cassette 100 after dismantling drug cassette 100 from body 20 and
Use, thus the body for being built-in with drive division and control unit can be used semi-permanently.
In addition, it can be included according to the device for introducing media 10 of the present embodiment:Lcd screen 12, it possesses in the upper of body 20
Surface;The switch (on/off) 14 of lcd screen 12, it possesses in the upper surface side of body 20;And power switch 15, it has
For in the side of body 20.
As shown in Fig. 2 lcd screen 12 can possess with touch-screen so that user can operate essence by touch
True infusion of medicine condition etc..
So, if user directly sets the infusion of medicine being automatically injected by the lcd screen 12 being made up of touch-screen
Condition etc., then it is built in the control unit of body 20 and controls drive division according to set condition, so as to according to set bar
Part and the medicine of drug cassette 100 can be stored in patient's injection automatically, accurately.
In addition, the various information such as battery dump energy, injection rate can be shown in lcd screen 12.
Fig. 3 is according to the bottom perspective view of Fig. 1 device for introducing media, and Fig. 4 is stood according to the decomposition of Fig. 3 device for introducing media
Body figure, Fig. 5 are according to the exploded perspective view of the drug cassette of one embodiment of the invention, and Fig. 6 is the drug cassette according to Fig. 5
Front view, Fig. 7 are according to the bottom perspective view of Fig. 5 drug cassette, and Fig. 8 is the upward view according to Fig. 5 drug cassette.
Reference picture 3 can include to Fig. 8 according to the device for introducing media 10 of one embodiment of the invention:Installation portion 21, it has
It is standby in the bottom of body 20 (being top when on the basis of Fig. 3) to install drug cassette 100;And cover body 40, it covers installation portion
21。
In addition, protruding little gear (pinion) 70 in installation portion 21, it can be formed and be installed in drug cassette 100
The rack (rack) 134 engaged in the case of dress portion 21 with little gear 70.
In detail, drug cassette 100 can include:Main body 110, it has the form that side 112 is unlimited, flat,
And the space 111 that internally there is medicine to be stored, and the row discharged in opposite side formed with the medicine for being stored in space 111
Outlet 115;Piston element 130, it discharges the medicine for being stored in space 111 to outlet 115;And lid 140, it is in piston
Unlimited side 112 with main body 110 coordinates and covers above-mentioned unlimited one in the state of part 130 coordinates with main body 110
Side 112.
In addition, the first patchhole 117 can be formed in the bottom surface of main body 110, installation portion 21 is installed in drug cassette 100
In the case of, the prominent little gear 70 for being formed at installation portion 21 inserts above-mentioned first patchhole 117.
Piston element 130 can include:Piston rod 132, it is formed with rack 134, and the rack 134 is in drug cassette 100
Engaged in the case of being installed on installation portion 21 with being inserted in the little gear 70 of the first patchhole 117;And piston 138, its with
Shape corresponding with the cross sectional shape in space 111 is formed at the end of piston rod 132.
So, i.e. in little gear 70 and the phase of rack 134 in the state of drug cassette 100 has been installed on installation portion 21
Mutually in the state of engagement, if little gear 70 rotates, rack 134 is linearly moved, and thus piston rod 132 is also linearly moved
Dynamic, so, piston 138 will be stored in the medicine in space 111 by the linear movement of piston rod 132 and towards outlet
The extruding of 115 directions is so as to the outside discharge medicine of main body 110.
In addition, the outer peripheral face in piston 138 can possess seal member 139, the seal member 139 is chimeric with space 111
And the extruding medicine of the state to be crimped with the medial surface of space 111.
In addition, can form rack-shaped pore-forming 135 in piston rod 132, the rack-shaped pore-forming 135 has 134 shapes of rack
Into medial surface 137.
For example, rack-shaped pore-forming 135 can be formed in the form of generally rectangular, so as to with rectilinear configuration along
At least one medial surface 137 that the moving direction of piston rod 132 is formed, rack 134 can be formed in above-mentioned medial surface 137
At least one medial surface 137.
So, in the case where drug cassette 100 is installed on installation portion 21, inserted by the first patchhole 117
Little gear 70 it is prominent to rack-shaped pore-forming 135 and engaged with rack 134.
Now, the diameter of the patchhole 117 of little gear 70 and first, the width size of rack-shaped pore-forming 135 are with phase
Size corresponding to mutually is formed, and rack 134 can be protruded in the medial surface 137 of rack-shaped pore-forming 135 and formed.
