Specific embodiment
In the following, the tube sealing liquid syringe driving means of the utility model is described in detail in conjunction with attached drawing.
It is small when big when pulsed refers in the utility model, there is certain variation.Pulsed washing pipe refers to washing pipe liquid
Size alternately rinses the pipeline of PICC or remaining needle.
The principles of the present invention are to push the pushing hands of syringe by the cam or eccentric wheel of uniform rotation, this
Sample, the promotion implemented on syringe are exactly that the pulse of mechanical periodicity pushes.
The driving means of the utility model includes bed body 10, sliding block 30, and tube sealing liquid syringe 20 is placed in bed body 10,
The pushing hands of tube sealing liquid syringe 20 is pushed with sliding block 30, as shown in Figure 1, 2.
Bed body 10 includes guide groove 14a, 14b；Here guide groove at least can be one, the attached situation for being illustrated as two,
When two guide grooves, the sliding of sliding block 30 is more stable.It certainly, is parallel between 2 or 2 situations with upper guide groove, each guide groove
's.
It further include the rack gear 13 parallel with guide groove on the upside of bed body 10.The first end of bed body further includes retaining wall 12, on retaining wall 12
It is formed with through-hole 15.Through-hole 15, which can be, only allows the nipple of tube sealing liquid syringe 20 to pass through, and is also possible to out larger, permits
Perhaps the cylinder of tube sealing liquid syringe passes through and the edge of cylinder outwardly protruded is resisted against 12 inside of retaining wall, as shown in Figure 1, 2.
It can also include handle on the downside of bed body 10, hold bed body 10 to facilitate.
Sliding block 30 is mainly made of supporting walls 31a, 31b, gear 35, actuator wheel 34.Actuator wheel 34 can be cam or
Eccentric wheel, shown in the accompanying drawings is a kind of cam of ellipse, but the embodiment of the actuator wheel of the utility model is without being limited thereto.
The number of supporting walls and the number of guide groove are corresponding.Supporting walls lower end is formed with convex block 33, the cross section pair of convex block 33
It should be in the cross section of guide groove 14a, 14b.In attached drawing, the cross section of convex block is up-narrow and down-wide isosceles trapezoid, can also there is other
Embodiment, such as discount vibram outlet shape, rectangle, pentagon etc., as long as to slide and cannot be from guide groove in convex block insertion guide groove
Upper opening in deviate from.
In the situation of multiple supporting walls, multiple supporting walls can be fixed together, such as by handle 32 shown in the drawings,
It is fixed together and facilitates multiple supporting walls cooperative motion in multiple guide grooves.
The upper end of supporting walls can be rotatably set axis, and being permanently connected on axis has gear 35 and actuator wheel 34.At one
The situation of supporting walls can be gear 35 and be located at supporting walls side, and actuator wheel 34 is located at the other side.
The situation that supporting walls are 2, can be gear 35 and actuator wheel 34 is located at the two sides of two supporting walls.It can also
To be that as shown in Figure 4, so that actuator wheel 34 is located between two supporting walls 31a, 31b, the two sides of such actuator wheel are supported
The protection of wall can unexpectedly rub with other objects to avoid actuator wheel, such as perfusion tube, clothing, sheet etc..
It, can be braked wheel in order to reduce the friction between the end face of tube sealing liquid syringe pushing hands and the curved surface of braked wheel 34
Surface design smooth and end face contact surface with pushing hands it is smaller.Alternatively, roller or rolling can be designed on the end face of pushing hands
Pearl, roller or ball can be multiple, can connect with roller or ball when guaranteeing that the different location of curved surface is contacted with pushing hands
Touching, so that friction is converted into rolling friction, thus frictional force very little.
In use, tube sealing liquid syringe is clipped between retaining wall and actuator wheel, by the uniform velocity pushing sliding block, the song of actuator wheel
Face exports motive force periodically changed, and thus tube-sealing solution is also pulsed output from syringe.
