Detailed description of the invention
As Figure 1-3, in the preferred embodiments of the present invention, described infusion pump self-locking liquid stopping clamp, comprise holder 1 and rotate clamp clip 2, hinged with holder 1 in the middle part of described rotation clamp clip 2, described holder 1 is provided with the face of being fixed and clamped 3 in hinged place, described rotation clamp clip 2 correspondence face 3 place that is fixed and clamped is provided with movable seal face 4, U-shaped extension spring 16 is provided with between described holder 1 and rotation clamp clip 2, and described U-shaped extension spring 16 one end is U-shaped knot, the other end is provided with two free ends, and spring is provided with on two free ends, two free ends are arranged symmetrically in the both sides rotating clamp clip 2.Concrete, described holder 1 is installed with link plate 14 by screw 17, described rotation clamp clip 2 outer end is provided with groove 15, two free ends of described U-shaped extension spring 16 are all fixed on link plate 14, the U-shaped structure of its other end is articulated in groove 15, and link plate 14 is arranged on the left of hinged place, groove 15 is arranged on the right side of hinged place.Described rotation clamp clip 2 is provided with shell fragment 5, and described shell fragment 5 is connected with rotation clamp clip 2 by elastic bar, and into a single integrated structure.
Further, described holder 1 is arranged on infusion pump panel 6, on described infusion pump panel 6, corresponding rotation clamp clip 2 place has and rotates clamp clip ejection hole 7, corresponding described shell fragment 5 place has shell fragment and ejects hole 8, described rotation clamp clip 2 stretches out and rotates clamp clip ejection hole 7, and the one end of stretching out is provided with press-side 9, and press-side 9 is provided with and rotates clamp clip and eject the limited block 10 matched in hole 7.Described infusion pump panel 6 is provided with pump door 11 in side, and described pump door 11 corresponding shell fragment 5 place is provided with protruding 12, and corresponding press-side 9 place is provided with press-side placing trough 13.
During use: three states can be divided into.
First A, B, C tri-points are set in described infusion pump self-locking liquid stopping clamp, wherein: A point is the installation site of link plate 14 on holder 1; B point is rotate clamp clip 2 position hinged with holder 1; C point is rotate the position of clamp clip 2 being installed U-shaped extension spring 16 groove 15.
When pump door is closed: as shown in Figure 4, when pump door 11 is closed, protruding 12 touch shell fragment 5, and promote shell fragment 5 and eject hole 5 through shell fragment and move to infusion pump panel 6 rear portion, then shell fragment 5 driven rotary clamp clip 2 turns clockwise around B point, in the press-side placing trough 13 simultaneously making press-side 9 enter on pump door 11, and withstand press-side 9 by press-side placing trough 13, make to rotate clamp clip 2 and stop the rotation.
Now be fixed and clamped face 3 is in released state with movable seal face 4, and transfusion device 18 can normally work; C point just in time rotates to the below of A, B line extended line around B point simultaneously, at this moment rotates the clockwise pulling force that clamp clip 2 is subject to U-shaped extension spring 16.
When pump door is opened: as shown in Figure 5, when pump door 11 is opened, because now C point just in time rotates to the below of A, B line extended line around B point, at this moment the clockwise pulling force that clamp clip 2 is subject to U-shaped extension spring 16 is rotated, rotate clamp clip 2 to continue to turn clockwise around B point, make the face of being fixed and clamped 3 and movable seal face 4 be in closure state, transfusion device 18 is clamped, makes transfusion device 18 stopping infusion.
Now rotate clamp clip 2 and stretch out rotation clamp clip ejection hole 7, shell fragment 5 stretches out shell fragment ejection hole 8 simultaneously, and C point is still in the below of A, B line extended line, at this moment rotates the clockwise pulling force that clamp clip 2 is still subject to U-shaped extension spring 16.
When transfusion device is installed: as shown in Figure 6, after pump door 11 is opened, manual promotion press-side 9 moves to infusion pump panel 6 rear portion, and driven rotary clamp clip 2 rotates around B point, the face of being fixed and clamped 3 and movable seal face 4 are opened, and be in released state, unclamp transfusion device 18, be convenient to the replacing of transfusion device 18.
Now C point is just in time rotated counterclockwise the top of A, B line extended line around B point, at this moment rotates the anticlockwise pulling force that clamp clip 2 is subject to U-shaped extension spring 16, makes the face of being fixed and clamped 3 and movable seal face 4 be in released state always.
Meanwhile, after rotation clamp clip 2 is rotated counterclockwise certain angle, ejects hole 7 by the limited block 10 on press-side 9 with rotation clamp clip and match, rotation clamp clip 2 is blocked, make to rotate clamp clip 2 and stop the rotation.
When replacing transfusion device 18 after, shut pump door 11, make described infusion pump self-locking liquid stopping clamp be again in pump door close time state.
Described infusion pump self-locking liquid stopping clamp, it improves unhandy problem during existing infusion pump replacing transfusion device, all the time press liquid stopping clamp without the need to finger when making to change tube for transfusion, both hands can be installed by tube for transfusion, thus make infusion pump installation or change tube for transfusion convenient.
