Detailed description of the invention
For summary of the invention of the present invention, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1-10, the disposable lower triggered safety hemostix of rapid-assembling can be realized, be made up of following a few part:
Comprise overcoat 1, overcoat has front opening end and rear opening end, the inner surface of sleeve side wall is arranged with two groups of raised ribs, 101, two groups of raised ribs that the line direction along the rear ends of overcoat extends and forms twice draw-in grooves 102.
Comprise inner sleeve 2, be inside placed in overcoat inner chamber, and can along the line direction linear slide of the rear ends of overcoat.The straight-line guidance structure matched is set usually between inner sleeve with overcoat, such as symmetrical and two guide protrusions 201 extended along inner sleeve rear ends line direction are set at the outer surface of sidewall of the inside race, the internal chamber wall of overcoat arranges symmetrical gathering sill, wherein gathering sill can directly be formed on the internal chamber wall of overcoat, two groups of raised ribs described above also can be set, between raised ribs, form gathering sill 103.By coordinating of guide protrusions and gathering sill, make inner sleeve linear slide in overcoat.The leading section of inner sleeve is provided with needle outlet 202, the rearward end of inner sleeve is opening end, the leading section of inner sleeve is stretched out from opening end before overcoat, and makes inner sleeve overhanging spacing by the inner retaining side 104 that is arranged on overcoat leading section and the fit structure of projection that is arranged on sidewall of the inside race.The sidewall of inner sleeve is arranged with the gathering sill 203 that two rear ends line directions along inner sleeve extend, and concrete, this gathering sill extends to the rear end face of inner sleeve, but leaves the distance of setting with the front end face of inner sleeve.Be respectively equipped with a flanging 204 in the position that the rearward end of inner sleeve is corresponding with arranging two gathering sills, two flangings are equipped with a width, and to be less than the gathering sill of opening 205, two opening of gathering sill width and correspondence position through, makes inner sleeve form expansion sleeve type structure.
Comprise blood taking needle 3, blood taking needle is placed in overcoat inner chamber, blood taking needle is made up of needle handle 301 and the needle body 302 be arranged on needle handle, the needle portion of needle body is stretched out from the front end of needle handle, needle handle is arranged with two guide vanes 303 corresponding with two gathering sills on interior cover, like this in the process of blood taking needle percussion, slide in two guide vanes, two gathering sills respectively on sidewall of the inside race, thus achieve blood taking needle linearly non-beat inserting needle.
Comprise bonnet 4, bonnet is fixed on the rear opening end of overcoat, and described bonnet is by covering the end 401 and two of being symmetrical arranged on lid end inner face press arm 402 and form, and two ends pressing arm form wedge shape plug by arranging wedge surface.
Comprise percussion spring 5, percussion spring is placed in the inner chamber of overcoat, and the leading section of percussion spring and rearward end are connected with the rearward end of needle handle and bonnet respectively.
Comprise sterile sealing cap 6, sterile sealing cap and needle portion are tightly connected, and its leading section is stretched out from the front end needle outlet of inner sleeve.
On above-mentioned needle handle, match with the opening of inner sleeve two flanging respectively and form blood taking needle locking structure in the leading section of two guide vanes, and make percussion spring be in compression to treat cock, concrete, width because of guide vane is greater than the width of corresponding flanging upper shed under natural shape body, therefore a spacing table top is formed on the both sides of flanging upper shed, the front end of guide vane is against on corresponding spacing table top, makes blood taking needle realize locking.Under the unexcited state of blood taking needle, two flangings of above-mentioned inner sleeve coordinate with the twice draw-in groove setting-in put outward respectively and form inner sleeve and limit swollen structure.Under the state of inner sleeve leading section retraction overcoat inner chamber, two wedge shape plugs on above-mentioned bonnet match with the opening on inner sleeve two flanging respectively, make inner sleeve distending, and form blood taking needle unlocking structure.The reason that the above-mentioned inner surface at sleeve side wall arranges raised ribs and forms draw-in groove is: because hemostix is when assembling, percussion spring has certain decrement, so certain active force is applied with to blood taking needle, because inner sleeve is thinner, for avoiding inner sleeve insufficient strength and stressed distending, therefore raised ribs being set on outer casing inner wall, forming draw-in groove, the flanging of inner sleeve is clamped, thus mistakenly hit is sent out or advanced primer ignition under unexcited state to avoid blood taking needle.The effective length of the above-mentioned draw-in groove formed by raised ribs and the position of distance overcoat rear end need to ensure under the unexcited state of hemostix on the one hand, flanging is fitted in draw-in groove, and needing the moment of percussion, flanging departs from the constraint of draw-in groove, thus be enclosed within ensure that bonnet press the effect of arm under and distending, realize the smooth unblock of blood taking needle.
After inner sleeve is assembled to overcoat, for ease of realize blood taking needle be installed to overcoat inner chamber time, with inner sleeve fast aligning position, the both sides that two flangings of inner sleeve are positioned at opening are arranged with the anticlinal stile of an anticlinal stile 206, two respectively further and form blood taking needle installation guiding structural.Concrete, when blood taking needle is installed, on blood taking needle needle handle two guide vanes are made to put the space that two anticlinal stiles are formed align with interior respectively, like this bonnet to be fixed on after overcoat after on opening end, the leading section of blood taking needle two guide vanes is pressed on the corresponding aperture position of two flangings respectively, and then achieves the only lock of blood taking needle.
Due to reasons such as extruding during for avoid in transportation or to store, the front end sponson of inner sleeve is bounced back, and causes blood taking needle mistakenly hit to be sent out.In the leading section of overcoat, further adapter sleeve is equipped with protective cap, and the front end sponson of inner sleeve is placed in protective cap.This protective cap and above-mentioned sterile sealing cap can adopt two style structure; Also can adopt integral structure, namely the front end of sterile sealing cap is connected with protective cap bottom interior surface.When protective cap and sterile sealing cap adopt two style structure, sterile sealing cap and the injection mo(u)lding of blood taking needle one mould, and when both adopt integral structure formula, sterile sealing cap and protective cap integrated injection moldings.
Originally the disposable lower triggered safety hemostix operation instruction of rapid-assembling can be realized:
When sterile sealing cap and protective cap adopt two style structure, the process of blood sampling is:
The first step: first pinch overcoat with a hand finger, another hand finger pinches protective cap, pulls up protective cap from the front end of overcoat, and makes the front end sponson of inner sleeve like this and the sterile sealing cap portion that stretches out from inner sleeve front end comes out;
Second step: pinch with finger the sterile sealing cap portion stretched out from inner sleeve front end, rotate a few circle, sterile sealing cap is loosened, and extracted the front end of sterile sealing cap from inner sleeve, like this, blood taking needle needle portion is just exposed in inner sleeve;
3rd step: pinch hemostix with finger, the needle outlet of inner sleeve front end is made to align finger abdomen by the person of adopting, and be applied to the power of overcoat towards the finger abdomen direction by the person of adopting, under this force, the front end sponson of inner sleeve is retracted in overcoat inner chamber gradually, be retracted in the process of overcoat inner chamber in inner sleeve, move after blood taking needle is synchronous under the effect of inner sleeve, and percussion spring is further compressed, when the front end sponson of inner sleeve will be retracted into overcoat inner chamber, the wedge shape plug that opening on inner sleeve flanging and bonnet press arm end starts to contact, in inner sleeve retraction process further, two wedge shape plugs pressing arm make two openings of inner sleeve flanging swell gradually respectively, when the size of opening swells to the width being a bit larger tham blood taking needle guide vane, blood taking needle departs from the restriction on inner sleeve flanging opening both sides, blood taking needle is unlocked, like this under the effect of rear end percussion spring, in the corresponding gathering sill that guide vane on blood taking needle needle handle puts in sliding into instantaneously, make blood taking needle fast downlink, penetrate into and refer in abdomen, then under the effect of percussion spring in fast retractile inner sleeve, and then medical personnel realize blood sampling.
When sterile sealing cap and protective cap adopt integral structure, the process of blood sampling is: first-selection pulls up protective cap, is also pulled up by sterile sealing cap simultaneously, next identical with the action of above-mentioned 3rd step, does not repeat them here.
The innovation reform that the disposable lower triggered safety hemostix that originally can realize rapid-assembling carries out for my invention " disposable touchpress safe hemostix causing no pain (patent No. CN201010574540.2) " and design.By the redesign of blood taking needle locking structure and unlocking structure, be enclosed within when being installed in overcoat in making, inner sleeve slips into the leading section of overcoat inner chamber instantaneously in " freely falling body " mode, thus realize disposable being in place, and then complete the assembling of inner sleeve fast, it need be placed on interior after in overcoat with Special-purpose forceps compared to existing, also need the mode forcing inner sleeve to head into the leading section of overcoat with " push rod " formula specific purpose tool, reduce the difficulty of assembling, significantly save and assemble man-hour, make original average used time 6-7 second, shorten to present 1.5-2 second, assembling work efficiency is made to improve 3.5-4 doubly, and then reduce assembly cost significantly.
