Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described.
Of the present utility model this cervical dilatation foley's tube as shown in Figures 1 to 6, comprises adapter 100, outer catheter 200, inner catheter 300 and haulage gear 400.
Adapter 100 is Y-shaped, and this adapter 100 has outer tunnel 110 and internal channel 120, and outer tunnel 110 is for connecting normal saline inlet, and internal channel 120 may be used for connecting liquid medicine.The side of adapter is provided with ribs 130, in order to improve pipeline strength.
This inner catheter 300 has certain hardness, and inner catheter 300 is connected to described internal channel 120, and the medicinal liquid of internal channel 120 enters cervix uteri by its axis hole 340.Described inner catheter 300 is provided with two developing marks 310, can by the position of the position judgment inner catheter 300 of this developing mark 310.Described expansion of balloon catheter also comprises a tinsel 320, and this tinsel 320 is through described inner catheter 300.This tinsel 320 may be used for the hardness improving inner catheter 300 further, keeps stretching into direction.In this utility model, the lateral wall of described inner catheter 300 is provided with groove 330, and this groove 330, along its axis direction opening, forms the circular arc of 3/4ths substantially.Axis hole and this groove 330 of inner catheter 300 are completely closed.
Outer catheter 200 adopts the plastic silicon glue material that can contact human body to make, and outer catheter 200 hollow form, its one end is connected to described outer tunnel 110, and the other end of described outer catheter 200 is provided with sacculus 210.This sacculus 210 is fixed on described inner catheter 300, is especially fixed on the front end of inner catheter 300.Normal saline enters sacculus 210 through outer tunnel 110, outer catheter 200, and sacculus 210 expands rear distraction cervix uteri.The medial wall of sacculus is provided with circular passage 211, and the contraction of circular passage 211 drives sacculus depression, as shown in Figure 2.
This haulage gear 400 is made up of slide bar 410 and pull rope 420, and described slide bar 410 is slidably arranged in described groove 330.Slide bar 410 is cylindric, and its external diameter is corresponding to groove 330, ensures that slide bar 410 can clog-free slip in groove 330.This slide bar 410 has a beeline channel 411 and wire hole 412, and one end of described wire hole 412 is connected to described beeline channel 411, and the other end stretches out from described groove 330.Relatively rotating of slide bar 410 and groove 330 can be limited, to keep the corresponding of wire hole 412 and groove 330 opening.One end of described pull rope 420 is fixed on described medial wall, and the other end of this pull rope 420 is successively through described circular passage 211, wire hole 412, beeline channel 411.With reference to Fig. 6, pull rope 420 is by straightway 421, link 422 and form around section 423, and the length of straightway and linkage section is substantially constant.From the outlet pulling traction rope 420 of beeline channel 411, pull rope 420 shortens, and the diameter around section 423 reduces, and drives the middle part of sacculus 210 to shrink.Pull slide bar 410, wire hole 412 changes relative to the position of sacculus, and then the direction of the contractility of adjustment sacculus 210, changes the punctured position of sacculus 210 and the expanded size of both sides, as Fig. 4,5.Described beeline channel 411 is parallel to the axis of described slide bar 410, and described slide bar 410 stretches out in described outer tunnel 110, to facilitate manually adjustment slide bar 410.
Preferably, change the axial length of outer catheter 200, the axial expansion length of adjustment sacculus 210.As Fig. 3, described outer catheter 200 is made up of the first conduit 220, elastic component 230 and the second conduit 240, described first tubes connection is to described adapter 100, described second conduit 240 is connected to sacculus 210, and the two ends of described elastic component 230 connect described first conduit 220 and the second conduit 240 respectively.Elastic component 230 can be a spring, for ensureing sealing, can adhere to a sealing ring 250 outside this spring.After sacculus 210 is expanded, the distance of the first conduit 220 and the second conduit 240 changes, and then changes the exterior contour after expanding.
The foregoing is only preferred embodiment of the present utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
