The specific embodiment

By reference to the accompanying drawings, the present invention is described in further detail.

As shown in the figure, valve module of the present invention is characterized in that: described valve module has comprised a syringe 12 and a valve cell 14, wherein on injector assembly 10, has a chamber 20, also comprises a plunger 22 simultaneously, forms cavity 24; Described cavity 24 contains a socket 26, and valve cell 14 is that valve cell 14 has outer package 32 and volume control device for chamber 24 and the pin 30 connected, and socket 26 is adjacent with positive interface tail end 1; The described first cloudy interface tail end 36 agrees with mutually with cloudy interface tail end 1, and positive interface tail end 2 38 combines with pin 30; Described valve cell 14 has the fluid transmission pipe 42 between cloudy interface tail end 1, positive interface tail end 2 38, on valve cell 14, also has valve member 44 and actuation member 46.On described positive interface tail end 38, an external screw thread sheath 50 is arranged, it has the convex 52 separated.Described valve member 44 includes a valve plug portion with respect to seat portion 56 54.Described valve member 44 slidably is arranged on outer shell component 58.On described valve member 44, also have flow opening 44b, and valve passage 44a is arranged on pipeline 42.Described valve member 44 includes an anchor flange 60.Described outer shell component 58 stops at radially inner end regions 62, and this end regions 62 is connected with cloudy interface tail end 1, and in should zone, also has the bias unit of Compress Spring 64 forms.

With reference to accompanying drawing, overall structure of the present invention as described above.The cavity 24 of wherein showing in Fig. 2 has a socket 26, just as described, the socket 26 of a medical instrument, valve cell 14 has outer package 32 and volume control device, controls fluid flow by outlet, and this flow control apparatus can operate to open socket 26, coupling part can be used to and connects and medical fitting, volume control device can be used to from medical treatment such as pins and closes the outlet valve unit, and keeps this to close, until again connect and medical instrument.In this case, chamber 20 comprises the outlet 26 adjacent with the first syringe sun interface tail end 34, and valve cell 14, and it comprises cloudy interface tail end 1, and this is and positive interface tail end 1.Valve cell 14 also comprises that a positive interface tail end 2 38 carries out combination with medical instrument.

Although in this case, chamber 20 and valve cell 14 separate each other, and their are possible in conjunction with forming, for example, and by cloudy interface tail end 1 is combined with positive interface tail end 1.Valve cell 14 has the fluid transfer pipe way 42 between negative and positive interface tail end, a valve gear, form with the valve member of valve cell 14, between be primary importance (as shown in FIG. 2) movably, passage wherein is closed, and in the second position (as shown in Figure 3), this pipeline is open.Actuating device, the form (being shown in Fig. 2) with actuated components 46, stretch out, and enters into positive interface tail end 2 38 from valve member 44.When the cloudy interface tail end of pin 30 combined with positive interface tail end 2 38, actuation member 46 was engaged to valve member 44 and activates it.

In addition, in the embodiment in Fig. 1 to Fig. 4, positive interface tail end 2 38 has an external screw thread sheath 50, its convex separated 52.In this case, external screw thread sheath 50 inner processes 52 of position between actuated components 46.Valve member 44 comprises a valve plug portion with respect to seat portion 56 54..This valve member 44 has a upper end, has been integrally formed cloudy interface tail end 1.Valve member 44. is installed on outer shell component 58 slidably.In this case, outer shell component 58 is engaged to positive interface tail end 2 38.Valve member 44 also has the valve plug portion 42 from cloudy interface tail end 1, and there, it has stopped adding of one or more horizontal mobility opening 44b, and extends to the valve passage 44a of pipeline 42.

In addition, valve member 44 comprises an anchor flange 60, directly or indirectly with 2 38 seats of positive interface tail end, to grappling flange 60, when valve is in the close position, as shown in Figure 2.On the contrary, as shown in FIG. 3, when valve is shown in an open position, positive interface tail end 2 38 separates from described grappling flange.Outer shell component 58 stops at a radially inner end regions 62, this zone is connected with positive interface tail end 1, and the bias unit of Compress Spring 64 forms is positioned at the end regions 62 of inner and outer shell, between grappling flange 60 bias voltages parts towards described primary importance to close the value of this valve cell.

Certainly, valve gear also can be used for the medical fluid delivery device with other, as the IV line, and conduit, infusion pump and similar.On valve cell, also can use syringe and other medical apparatus not to adopt general De De road to be connected layout.
