The specific embodiment
The utility model is described in further detail below in conjunction with specific embodiments and the drawings; set forth more details in the following description so that fully understand this utility model; but this utility model obviously can be implemented with the multiple alternate manner that is different from this description; those skilled in the art can do similar popularization, deduction according to practical situations under the situation of this utility model intension, therefore should be with the content constraints of this specific embodiment protection domain of the present utility model.
As shown in Figure 1 to Figure 3, the buttferfly-type needle assembly comprises buttferfly-type pin 1 and protective sleeve 2.Buttferfly-type pin 1 is taken in by protective sleeve 2 or ccontaining or reception, state as shown in Figure 1 to Figure 3, and the pin portion of buttferfly-type pin 1 passes protective sleeve 2, is in not protected user mode, and user can and utilize pin portion to puncture by means of alar part this moment.To shown in Figure 10, the pin portion of buttferfly-type pin 1 is withdrawn in the protective sleeve 2, is in shielded retracted mode as Fig. 8.
To shown in Figure 14, buttferfly-type pin 1 has pin portion 12, shank 11 and alar part 13 as Figure 11, and alar part 13 has front 131 and reverse side 130, and reverse side 130 provides non skid matting usually, and front 131 provides sign usually, is generally smooth surface.Shank 11 is fixed on the centre of the reverse side 130 of alar part 13, and the front end of shank 11 connects pin portion 12 and the rear end generally is used for connecting flexible pipe 3 (as shown in figure 15).
To shown in Figure 7, protective sleeve 2 be the integral piece of injection mo(u)lding as Fig. 4, comprises that needle point protects 21, loam cake 22 and lower cover 23, and loam cake 22 and lower cover 23 are microscler parts, and it extends axially protective sleeve 2, has far-end and near-end respectively.Orientation aforementioned and described later term, for example upper and lower, far away, near, forward and backward etc. generally is normally to use the state of buttferfly-type assembly to be reference with respect to user.Needle point protection 21 be cylinder, and the center has the pin hole 210 that axially runs through, and it is used for receiving the needle point of the pin portion 12 that is in retracted mode, provides enclosed construction around needle point circumferential, to play protection people's effect, avoids needle point to sting and hurts sb.'s feelings.
Be formed with clamping structure between loam cake 22 and the lower cover 23, this clamping structure can cooperate with the alar part 13 of buttferfly-type pin 1, so that buttferfly-type pin 1 is fastened on as shown in Figure 1 user mode or locked retracted mode as shown in Figure 8, and clamping structure allows that also buttferfly-type pin 1 (applies by alar part 13 in the external force of design, if do not apply external force, then stiff) effect is axially movable to retracted mode down.Clamping structure can have multiple implementation.In preferred embodiment of the present utility model, clamping structure such as Fig. 4 are to shown in Figure 7, the lower limb of loam cake 22 located adjacent proximal end is formed with guiding domatic 220, this guides domatic 220 to play the effect that stops the 1 unexpected withdrawal of buttferfly-type pin on the one hand, when being convenient to the buttferfly-type pin 1 under the near-end pulling user mode on the other hand alar part 13 is played guiding function, make buttferfly-type pin 1 axially movable to retracted mode smoothly.The lower limb at loam cake 22 middle parts provides to lower convexity 224, until the top edge of lower cover 23, as shown in Figure 7, the middle part of loam cake 22 and lower cover 23 is enclosed construction all around like this to the protrusion distance of lower convexity 224.Loam cake 22 is adjacent to the lower limb of lower convexity 224 and is formed with into for the recess 221 that receives alar part 13, and recess 221 provides sidewall 2210, is used for cooperating with the blocking of 13 one-tenth 90 degree of alar part.
Continuation is with reference to Fig. 4 to Fig. 7, and lower cover 23 forms first and raises up and 231, the first raise up and 231 also be used for and 13 one-tenths 90 degree of alar part blocking cooperation in the inboard to lower convexity 224.The lower limb of lower cover 23 in the below of recess 221 is formed with second and raises up and 230, the second raise up and 230 be used for engaging with the hole slot 132 of alar part 13.
At the locking state of withdrawal, the alar part 13 of buttferfly-type pin 1 and the sidewall 2210, first of recess 221 raise up 231, second raise up 230 at least one play mating reaction.Second raises up 230 can not snap onto in the hole slot 132, and this moment, the sidewall 2210 and first 231 pairs of alar parts 13 that raise up played the blocking effect, and buttferfly-type pin 1 is locked in position as shown in Figure 8, made buttferfly-type pin 1 not move forward.Second raises up 230 snaps onto in the hole slot 132, and then sidewall 2210, first raises up and 231, second raises up and 230 play the blocking effect simultaneously.Sidewall 2210, first raises up and 231, second raises up and 230 provide triple blocking effects, and this will prevent thoroughly that buttferfly-type pin 1 from deviating from practice.
Be extruded with the keeper 223 of anchor shape at the near-end of loam cake 22, correspondingly, at the near-end of lower cover the lockhole 234 of step is arranged, keeper 223 is formed by elastomeric material, the size of keeper 223 is slightly larger than the size of lockhole 234, and keeper 223 and lockhole 234 just can removably engage like this.
Alar part 13 is that flexible material is made, and when medical personnel folded grasping alar part 13 in use, alar part 13 was more soft, and is easier to be folding, therefore obtains more grasping space.Alar part 13 can strut the centre of loam cake 22, lower cover 23 when crossing the enclosed construction of loam cake 22, lower cover 23 centres, and loam cake 22, lower cover 23 meeting elastic resets form enclosed construction again afterwards.
In other embodiment of the present utility model, alar part 13 can be one-body molded or independent molding and bonding by glue with shank 11.The Tip protection head 21 of protective sleeve 2, loam cake 22, lower cover 23 also can be to link together through folding, locking bolt, adhesion or welding after the molding respectively.
As Figure 11, shown in Figure 1, the front 131 of alar part 13 and the downside of loam cake 22 are toward each other, the upside of reverse side 130 and lower cover 23 toward each other, the sword face groove of the needle point 120 of pin portion 12 and positive 131 be same towards, and needle handle 11 is positioned at reverse side 130 sides of alar part 13.
As shown in figure 15, after the tail end of shank 11 connects flexible pipe 3, just can link together with hemostix or transfusion device.
In the previous embodiment, because protective sleeve 2 has needle point protection 21, after the needle point withdrawal, by complete closed, therefore inevitablely can not cause unexpected puncture injury around it, perhaps wear the infection risk that silk causes.And the part because protection 21 is formed in one, simple in structure, the surface is slick and sly or smooth, does not have outthrust, has feel preferably, therefore user is had better protection.
When protective sleeve 2 integral body were integrated injection molding, its building block is few, and was therefore simple in structure, was easy to produce in batches, and cost is low.
Though this utility model with preferred embodiment openly as above, but it is not to limit this utility model, any those skilled in the art are not in breaking away from spirit and scope of the present utility model, can make possible change and modification, aforesaid content is not limited to venous blood collection or puncture transfusion, also can be other medical applications.Therefore, every content that does not break away from technical solutions of the utility model, all falls within the protection domain that this utility model claim defines any modification, equivalent variations and modification that above embodiment does according to technical spirit of the present utility model.
