Detailed description of the invention
Embodiments of the invention are described below in detail, and the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or has the element of same or like function from start to finish.
In describing the invention, it will be appreciated that, term " " center ", " longitudinally ", " laterally ", " length ", " width ", " thickness ", on " ", D score, " front ", " afterwards ", " left ", " right ", " vertically ", " level ", " push up ", " end ", " interior ", " outward ", " axially ", " radially ", " circumferential ", the orientation of the instruction such as " back and forth " or position relationship are for based on orientation shown in the drawings or position relationship, it is for only for ease of the description present invention and simplify description, rather than device or the element of instruction or hint indication must have specific orientation, with specific azimuth configuration and operation, therefore it is not considered as limiting the invention.
Additionally, term " first ", " second " are only used for describing purpose, and it is not intended that instruction or hint relative importance or the implicit quantity indicating indicated technical characteristic.Thus, define " first ", the feature of " second " can express or implicitly include at least one this feature.In describing the invention, " multiple " are meant that at least two, such as two, three etc., unless otherwise expressly limited specifically.
The embodiment describing below with reference to accompanying drawing is exemplary, it is intended to is used for explaining the present invention, and is not considered as limiting the invention.It is described in detail below in conjunction with each technical scheme to the present invention for the specific embodiment.
As Fig. 1～3 show, the sealing shroud 1 of the present invention includes: seal body 10 and installation chimb 20.Wherein, described installation chimb 20 is positioned on the lateral surface of described sealed cylinder 10.Preferably, the material of described sealing shroud 1 is isoprene or silica gel.
Described seal body 10 includes: sealed cylinder 11 and some sealing flaps 12.Wherein, the through setting of described sealed cylinder 11, and described sealed cylinder 11 has upper end open and lower ending opening, the upper end of described some sealing flaps 12 is connected with the lower ending opening of described sealed cylinder 11, and described lower ending opening realizes selectively opened or Guan Bi by described some sealing flaps 12.Described sealed cylinder 11 is made of one piece with some sealing flaps 12, and described one-body molded mode can be injection etc..It should be noted that " upper end " referred to herein and " lower end " be with puncture outfit puncture direction as reference direction, i.e. the direction by " upper end " sensing " lower end " is the puncture direction of puncture outfit.In like manner, following " on ", D score is all with described puncture direction as reference direction.
As in figure 2 it is shown, specifically, when insert puncture core bar when, under puncturing the active force that core bar applies, some sealing flaps 12 are separated from each other, thus the lower ending opening of sealed cylinder 11 is opened, and puncture cannula is internally formed can the passage of supplied gas circulation；When extracting puncture core bar, puncturing the active force disappearance that core bar applies, some sealing flaps 12 close under natural resiliency restoring force and gas shock power effect automatically, thus lower ending opening respective closed.Now, the lower edge 123 of described some sealing flaps 12 abuts, lower ending opening is closed by some sealing flaps 12, and the air-flow of the upper and lower both sides of some sealing flaps 12 cannot circulate.
Further, in above-mentioned embodiment, for the ease of the automatic Guan Bi of some sealing flaps 12, and good sealing is formed.Arbitrary sealing flap 12 has end face 120 and the bottom surface 121 opposing with described end face 120, and wherein, described end face 120 is arranged towards described upper end open, and described bottom surface 121 forms the acting surface that the gas with perfusion in abdominal cavity of patients acts on.The curved surface that described bottom surface 121 is indent.Bottom surface 121 is designed as the curved surface of indent, for opposite planar, the force-bearing surfaces increasing bottom surface 121 amasss, thus when puncturing core bar and extracting, bottom surface 121 can be by bigger active force, under this active force, be conducive to the Guan Bi of some sealing flaps 12, and form good sealing, it the sealing of passage that puncture cannula formed has been effectively ensured, it is to avoid the generation of leakage problem.
Additionally, be additionally provided with protruding 122 on the end face 120 of arbitrary sealing flap 12, the described effect of protruding 122 is: the 1st, its intensity that can improve described sealing flap 12 and elastic-restoring force, the beneficially Guan Bi of sealing flap 12；2nd, sealing flap 12 can be played a protective role by it because, when puncture core bar tip pass through when, can first with described protruding 122 thus avoid damaging sealing flap 12., described protruding 122 extend to the lower end of described sealing flap 12 end face from the upper end of the end face of described sealing flap 12.Preferably, the described thickness of protruding 122 from top to bottom, is first gradually reduced, then is gradually increased, be finally gradually reduced.Being arranged such, the angle being formed between protruding 122 is less, is conducive to protecting to sealing flap 12.Because if the angle between protruding 122 is relatively big, being unfavorable for that first the tip puncturing core bar contacts with protruding 122..Wherein, the corresponding part of maximum thickness is positioned at the zone line of place end face.
As a kind of embodiment, the quantity of described sealing flap 12 is two, and now, two sealing flaps 12 are symmetrical arranged.Alternately, the quantity of described sealing flap 12 can also be three, and now, the lower edge of three sealing flaps 12 cooperates, and the lower edge of three sealing flaps 12 is Y-shaped.The quantity of described sealing flap 12 can also be four, and now, the lower edge of four sealing flaps 12 cooperates, and the lower edge of four sealing flaps 12 is cross.It should be noted that in other embodiments, the quantity of sealing flap 12 can be set greater than four as required, it is preferable that multiple sealing flaps are symmetrical arranged, and are not illustrated herein.
Described installation chimb 20 is used for realizing that installation in puncture outfit for the sealing shroud is fixed.Specifically, described installation chimb 20 is positioned on the lateral surface 110 of described sealed cylinder 11, described installation chimb 20 is connected with the lateral surface of described sealed cylinder 11, or, described installation chimb 20 integrally extends on described lateral surface 110, described seal body 10 is made of one piece with installing chimb 20, and described one-body molded mode can be injection etc..Meanwhile, described installation chimb 20 is perpendicular with described lateral surface.
Additionally, be further opened with some installing holes 21 on described installation chimb 20.Preferably, described installation chimb 20 is loop configuration, and the circumferential direction that described some installing holes 21 install chimb 20 along described annular is equidistantly spaced.Further, having stage portion 22 between described installation chimb 20 and the lateral surface of described sealed cylinder 11, described stage portion 22 is positioned on the bottom surface of described installation chimb 20, and described stage portion 22 is arranged continuously.
Based on sealing shroud 1 as above, the present invention also provides a kind of puncture outfit, and described lancet device has sealing shroud as above.
In sum, the sealing shroud of the present invention is by being optimized design to sealing flap so that when extracting puncture core bar, sealing shroud can preferably close, and the sealing of passage that puncture cannula formed is effectively ensured, it is to avoid the generation of leakage problem.
