Specific embodiment
The purpose of the present invention, advantage and feature, by by the non-limitative illustration of preferred embodiment below carry out diagram and
It explains.These embodiments are only the prominent examples using technical solution of the present invention, it is all take equivalent replacement or equivalent transformation and
The technical solution of formation, all falls within the scope of protection of present invention.
Present invention discloses a kind of infusion pipeline flow-stopping clips, as depicted in figs. 1 and 2, the infusion pipeline flow-stopping clip 1 include according to
The arc section 20, first of secondary connection presses section 30, U-bend section 40 and the second pressing section 50.It is described first pressing section 30 with
Arc section 20 and 40 joining place of U-bend section are respectively arranged with the first guide hole and the second guide hole worn for perfusion tube, and first presses
The inside of pressure section 30 and the second pressing section 50, which is respectively equipped with, squeezes seat 400 and extrusion 200, the extruding seat 400 and extrusion
200 for carrying out extruding fluid stopping to perfusion tube, under the transition of U-bend section 40, at the extruding seat 400 and extrusion 200
In face position, extruding fluid stopping can be carried out to the perfusion tube worn.
Mutually matched lockable mechanism 100, the lockable mechanism are equipped in the free end of arc section 20 and the second pressing section 50
Fluid stopping state can be kept to through extruding seat 400 and the perfusion tube after extruding of extrusion 200.Above the extruding seat 400, and/
Or its at least side, it is provided with the position-limit mechanism 300 for limiting perfusion tube offset, the position-limit mechanism 300 includes at least one
To limited post, each pair of limited post includes two limited posts, and perfusion tube is passed through between pairs of limited post.Each pair of limited post
Shape be cubold, cylindrical body or semicylinder or be an irregular cylinder, the vertical plane of the cylinder is by a plane and one
Curved surface closing surrounds, the plane be arranged the perfusion tube inside, use be in the limited post being arranged in pairs two planes it
Between.
Specifically, in the technical scheme, first arc section 20, first presses section 30, U-bend section 40 and the
Two press the of same size of sections 50, between 8 ~ 10mm, preferably 9mm, and the radian of first arc section 20 is
8mm, the radian of the U-bend section 40 are 6.5 ~ 7.5mm, preferably 7mm, and the width of the flow-stopping clip ontology 1 is 8 ~ 10mm.
Certainly in other embodiments, the size of the ontology can also be that other feasible parameters or equal proportion zoom in and out, and
And the shape of the ontology can also be other feasible shapes, such as has opening and is open out various equipped with lockable mechanism
It is trapezoidal etc..
Why flow-stopping clip ontology in the present embodiment is preferably above-mentioned structure, is mainly considered: in locking process
In, the lower end of the first pressing section 30 and the second pressing section 50 is deformed using U-bend section as supporting point, if U-shaped
Bending section is plane, then in deformation process, plane is more difficult to be deformed, thus can only be often the first pressing section and second by
Pressure section is bent in opposite directions keeps their upper end close, at this point, the deformation extent of the first pressing section and the second pressing section is larger, easily occurs
The case where bending damage；And the structure of bending section is used, in deformation process, itself is more variable for bending section compares plane
Shape, thus, since U-bend section 40 is also bent, the deformation extent of the first pressing section and the second pressing section is all smaller, so
The problem of bending damage will not occur.
The free end 111 of the arc section 20 is equipped with the first buckle 60, if there is gap setting on the inner wall of the free end
Dry convex ribs, the purpose of convex ribs setting are easy for user and facilitate carry out locking in operation, and user is releasing locking
Impetus is in free end in state operating process, since ontology is relatively good when releasing locking breaks into two with one's hands for the settings of the convex ribs.
As shown in figure 3, the movable end 311 of the second pressing section 30, which is provided with, cooperatively forms institute with first buckle 60
State the second buckle 70 of lockable mechanism 100.First buckle 60 includes the protrusion 62 with arc section 61, described raised 62 and
The free end 111 encloses a card slot 63, and second buckle 70 includes the boss 71 to match with the card slot 63, and
The boss 71 is and the matched chamfer shape of the arc section 61 towards described first buckle one jiao 72 of 60.
Gap setting has several convex ribs 80, the convex ribs 80 on the outer wall of the first pressing section 30 and the second pressing section 40
For when pressing the first pressing section 30 and the second pressing section 50, increasing finger and the first pressing section and the second pressing
Frictional force between section, consequently facilitating operation.
First buckle is clasped to form lockable mechanism with second, and due to the shape of the first buckle and the second buckle
Shape feature therefore, can be smooth between the lead angle of the second buckle and the arc section of the first buckle during the locking of flow-stopping clip
Realization sliding, the case where being not in card resistance realizes flow-stopping clip so that the protruding end of boss be made to be easier to be embedded into card slot
Pinching.

When using flow-stopping clip of the invention, the course of work is as follows: first leading perfusion tube through the first guide hole and second
Hole, perfusion tube is located in the guiding channel of the first guide hole and the second guide hole at this time, and perfusion tube is arranged in first limited post
301 and second between limited post 302, when not needing to carry out fluid stopping, keeps normality.
When needing to carry out fluid stopping, operator grasps the flow-stopping clip, and the convex ribs of section 50 are pressed with thumb press second
Region, while palm and the first pressing 30 contact area of section force, make the upper area of the first pressing section 30 to the second pressing section
50 directions are mobile, and the vertex of pinching part is connected to perfusion tube, squeezes perfusion tube.Due to being provided at least a pair of of limit
Column, the perfusion tube being arranged between the first guide hole and the second guide hole are able to maintain in the middle position for squeezing seat 400, in this way,
When extrusion 200 and squeeze seat 400 it is close to each other, perfusion tube is clamped when, it can be ensured that perfusion tube can be pressed from both sides completely
Firmly, will not be inclined there is a situation where pressing from both sides, play the purpose of complete fluid stopping, folder is perfusion tube, only be liquid inside perfusion tube.
When needing to release lockup state, flow-stopping clip is grasped, the convex ribs region of pressing the second pressing section 50 and the
The convex ribs region of one pressing section 30, exits the protruding end of boss 71 from card slot, at this point, being applied with another hand to press section
The lifting force of oblique upper makes raised height be higher than boss, unclamps again the finger of pressing the second pressing section, the second pressing section is certainly
It restores to the original state under the reaction of body deformation force, as the second pressing section restores to the original state,
The program can limit swing of the long duct in flow-stopping clip, and then improve and press from both sides inclined phenomenon, and it is abnormal to improve blood backflow.This
Invention optimizes product structure, ensures that long duct is not in folder inclined phenomenon under the premise of retained product small and exquisite feature.
Still there are many embodiment, all technical sides formed using equivalents or equivalent transformation by the present invention
Case is within the scope of the present invention.
