The specific embodiment
As Figure 1-3, in the preferred embodiments of the present invention, described infusion pump self-locking liquid stopping clamp, comprise holder 1 and rotation clamp clip 2, described rotation clamp clip 2 middle parts and holder 1 are hinged, described holder 1 is provided with the face of being fixed and clamped 3 in the hinged place, described rotation clamp clip 2 correspondences face 3 places that are fixed and clamped are provided with movable seal face 4, be provided with U-shaped extension spring 16 between described holder 1 and the rotation clamp clip 2, and described U-shaped extension spring 16 1 ends are the U-shaped knot, the other end is provided with two free ends, and is provided with spring at two free ends, and two free ends are arranged symmetrically in the both sides of rotation clamp clip 2.Concrete, be installed with link plate 14 by screw 17 on the described holder 1, described rotation clamp clip 2 outer ends are provided with groove 15, two free ends of described U-shaped extension spring 16 all are fixed on the link plate 14, the U-shaped structure of its other end is articulated in the groove 15, and link plate 14 is arranged on the left side, hinged place, and groove 15 is arranged on the right side, hinged place.Described rotation clamp clip 2 is provided with shell fragment 5, and described shell fragment 5 links to each other with rotation clamp clip 2 by elastic bar, and into a single integrated structure.
Further, described holder 1 is arranged on the infusion pump panel 6, corresponding rotation clamp clip 2 places have the rotation clamp clip and eject hole 7 on the described infusion pump panel 6, corresponding described shell fragment 5 places have shell fragment and eject hole 8, described rotation clamp clip 2 stretches out the rotation clamp clip and ejects hole 7, and be provided with press-side 9 at an end that stretches out, and press-side 9 is provided with and rotates clamp clip and eject the limited block 10 that matches in hole 7.Described infusion pump panel 6 is equipped with pump door 11 in a side, and described pump door 11 corresponding shell fragments 5 places are provided with projection 12, and corresponding press-side 9 places are provided with press-side placing trough 13.
During use: can be divided into three states.
Earlier A, B, three points of C are set in described infusion pump self-locking liquid stopping clamp, wherein: the A point is the installation site of link plate 14 on holder 1; The B point is the hinged position of rotation clamp clip 2 and holder 1; The position of C point on the rotation clamp clip 2 U-shaped extension spring 16 usefulness grooves 15 being installed.
When the pump door is closed: as shown in Figure 4, when pump door 11 is closed, projection 12 is touched shell fragment 5, and promote shell fragment 5 and pass shell fragment and eject hole 5 and move to infusion pump panel 6 rear portions, shell fragment 5 driven rotary clamp clips 2 turn clockwise around the B point then, make press-side 9 enter in the press-side placing trough 13 on the pump door 11 simultaneously, and withstand press-side 9 by press-side placing trough 13, make rotation clamp clip 2 stop the rotation.
The face 3 that is fixed and clamped this moment is in released state with movable seal face 4, but transfusion device 18 operate as normal; The C point just in time rotates to the below of A, B line extended line around the B point simultaneously, at this moment rotates the clockwise pulling force that clamp clip 2 is subjected to U-shaped extension spring 16.
When the pump door is opened: as shown in Figure 5, when pump door 11 is opened, because this moment, the C point just in time rotated to the below of A, B line extended line around the B point, at this moment rotate the clockwise pulling force that clamp clip 2 is subjected to U-shaped extension spring 16, rotation clamp clip 2 continues to turn clockwise around the B point, make the face that is fixed and clamped 3 and movable seal face 4 be in closure state, transfusion device 18 is clamped, make transfusion device 18 stop transfusion.
Rotate clamp clip 2 this moment and stretch out the rotation clamp clip and eject hole 7, shell fragment 5 stretches out shell fragment and ejects hole 8 simultaneously, and the C point still is in the below of A, B line extended line, at this moment rotates the clockwise pulling force that clamp clip 2 still is subjected to U-shaped extension spring 16.
When transfusion device is installed: as shown in Figure 6, after pump door 11 is opened, manually promoting press-side 9 moves to infusion pump panel 6 rear portions, and driven rotary clamp clip 2 rotates around the B point, make the face that is fixed and clamped 3 and movable seal face 4 open, and be in released state, and unclamp transfusion device 18, be convenient to the replacing of transfusion device 18.
This moment, the C point just in time was rotated counterclockwise the top of A, B line extended line around the B point, at this moment rotated the anticlockwise pulling force that clamp clip 2 is subjected to U-shaped extension spring 16, made the face that is fixed and clamped 3 and movable seal face 4 be in released state always.
Simultaneously, after rotation clamp clip 2 is rotated counterclockwise certain angle, ejects hole 7 by the limited block 10 on the press-side 9 with the rotation clamp clip and match, will rotate clamp clip 2 and block, make rotation clamp clip 2 stop the rotation.
After changing transfusion device 18, shut pump door 11, the state when making described infusion pump self-locking liquid stopping clamp be in the pump door again to close.
Described infusion pump self-locking liquid stopping clamp, unhandy problem was improved when it changed transfusion device to existing infusion pump, need not finger when make changing tube for transfusion and press liquid stopping clamp all the time, but both hands are installed tube for transfusion, thereby make infusion pump install or to change tube for transfusion convenient.
