Fig. 1 is the schematic diagram of the fluid infusion pipeline assembly for being administered patient.Fig. 2 a to Fig. 2 f It it is the puncture needle receiver for fluid infusion pipeline assembly according to a kind of embodiment of the present utility model Schematic diagram, wherein, Fig. 2 a and Fig. 2 e be fluid infusion pipeline assembly use before puncture needle receiver close View when closing, state when Fig. 2 b is to tear release paper before fluid infusion pipeline assembly uses is shown Being intended to, Fig. 2 c is puncture needle receiver view when opening, and Fig. 2 d is fluid infusion pipeline group View when part is again switched off after using after pin is received, Fig. 2 f is single puncture needle receiver Schematic diagram.

As shown in Fig. 1 to Fig. 2 f, present embodiments provide for a kind of wearing for fluid infusion pipeline assembly Pricker receiver 1, this puncture needle receiver 1 includes box body 11 and lid 12, box body 11 include for Receive the puncture needle incorporating section 111 of puncture needle 2 and for receiving the flap incorporating section of the flap 3 of puncture needle 112, wherein, puncture needle incorporating section 111 is positioned at the bottom of flap incorporating section 112, with flap incorporating section 112 Being connected, the junction of puncture needle incorporating section 111 and flap incorporating section 112 has to stretch into for puncture needle wears First opening 113 of pricker incorporating section, lid 12 is for engaging with box body 11 to receive puncture needle and flap It is contained in box body 11.

Preferably, puncture needle incorporating section 111 be downwardly extend out from the bottom of flap incorporating section 112 in The cavity of cone shape, with the puncture needle 2 of storage bending (such as, puncture needle 2 can be 90 degree curved The draw point of folding).Box body 11 and lid 12 are all made of plastics, and puncture needle incorporating section 111 and flap are received Receive the one-body molded formation in portion 112 box body 11.The puncture needle receiver 1 shape in approximately parallelepiped body, its end The puncture needle incorporating section of a cone shape is stretched out in portion.

The passed through for the flexible pipe 4 that is connected with puncture needle 2 it is provided with on the sidewall of flap incorporating section 112 Two openings 114.At the first opening 113, it is provided with the pin supporting construction 118 supporting puncture needle 2, is protecting The flap supporting construction 119 supporting flap it is provided with on the bottom of wing incorporating section 112.By supporting construction with The cooperation of lid, in transport or storing process, puncture needle and the flap of fluid infusion pipeline assembly will not Puncture needle receiver moves up and down.Preferably, lid also can be provided with the supporting construction matched, Do not move up and down in puncture needle receiver with the most fixing puncture needle and flap.Preferably, second open The height of mouth 114 can match with the height of pin supporting construction so that infusion flexible pipe 4 enters puncture needle The position of receiver 1 will not be bent because height is different.

Puncture needle receiver 1 includes that buckle structure, buckle structure include a pair snap features 13a and 13b, its Middle snap features 13a is arranged on box body 11, and snap features 13b is arranged on lid 12, snap features 13a, Can interact between 13b with by box cover buckling on box body, it is to avoid puncture needle receiver 1 in transportation It is opened.As shown in Fig. 2 a and Fig. 2 c, fluid infusion pipeline assembly before use, puncture needle 2 and flap 3 All being accommodated in puncture needle receiver 1, now puncture needle receiver 1 is closed, by snap features 13a, 13b Between interaction so that transport storing process in puncture needle receiver 1 be not switched on, needs use During fluid infusion pipeline assembly, puncture needle receiver 1 can be opened, with puncture needle and flap are taken out into Exercise and use.Such as, can be interference fit between snap features 13a, 13b, therefore transportation puncture Pin receiver 1 is difficult to be opened, and the interference of the interference fit between snap features 13a, 13b is little simultaneously, Thus puncture needle receiver 1 can be opened when needs use fluid infusion pipeline assembly.Such as, buckle Feature 13a and 13b are all made of plastics, and snap features 13a is the groove being arranged on box body 11, and buckle is special Levying 13b is the projection being arranged on lid 12, and when closing puncture needle receiver, the deformation utilizing plastics is special Property makes the projection of snap features 13b can clamp-on in the groove of snap features 13a, snap features 13a, 13b Between match to keep puncture needle receiver 1 to be closed.

Puncture needle receiver 1 may also include another buckle structure, and this buckle structure includes snap features 14a And 14b, the interference fit between snap features 14a, 14b is bigger.Owing to fluid infusion pipeline assembly is one Plant discardable consumptive material, the most in the present embodiment, after fluid infusion pipeline assembly uses, need Puncture needle and flap it is accommodated in puncture needle receiver again and to carry out again abandoning (as shown in Figure 2 d), Owing to the interference of snap features 14a, the interference fit of 14b is relatively big, buckle it at snap features 14a, 14b card After, interaction between the two can be closed receiver and is not easy to be opened, thus prevents the puncture discarded Draw point injure patient or other people.Such as, snap features 14a and 14b are all made of plastics, snap features 14a is the hasp stretched out away from box body 11 side, is provided with projection, and snap features 14b is The groove being arranged on lid, the bump sizes of snap features 14a is more than the groove size of snap features 14b. Puncture needle and flap be again accommodated in puncture needle receiver needs to abandon time, utilize the change of plastics Shape characteristic, can be by the protruding groove inserting snap features 14b of snap features 14a.Simultaneously because buckle The bump sizes of feature 14a differs more with the groove size of snap features 14b, convex in snap features 14a Rise insert snap features 14b groove in after, between the two interact so that puncture needle receiver not Easily it is opened.

It is additionally provided with the release paper 32 pasted on pad for flap 3 on the box body 11 of puncture needle receiver 1 to stretch out The 3rd opening 115.As shown in Figure 2 a and 2 b, before using fluid infusion pipeline assembly, puncturing Under pin receiver 1 closed mode, user can be torn release paper 32 safely by the 3rd opening 115, To be exposed in air by stickup pad, fluid infusion pipeline assembly can be received by user from puncture needle afterwards Taking out in box 1, puncture needle 2 is punctured into patient skin by hand-held flap 3, now pastes pad Pasting in patient With fixing puncture needle 2 on skin.Release paper herein is that one is i.e. possible to prevent to paste pad adhesion, the most permissible Protection is pasted and is padded not by the separate paper of outside contamination, and release paper is releasably attachable to paste pad before use On, need to be torn off this release paper when using stickup pad.

The 4th opening 121, and/or the end of flap incorporating section 112 it is provided with on the lid 12 of puncture needle receiver 1 It is provided with in portion on the 5th opening 116, and/or described puncture needle incorporating section and is provided with the 6th opening 117.This Sample, under puncture needle receiver closure state, can wear being accommodated in fluid infusion pipeline assembly therein Pricker and flap carry out disinfection.

Understanding in conjunction with Fig. 2 a to Fig. 2 e, in the present embodiment, puncture needle receiver 1 in transit and uses Front lid 2 is closed, thus protect puncture needle 1 not by accidental damage or injure patient or other people.Use Before, under lid 2 closed mode, user can be torn release paper by the 3rd opening 115, then leads to Cross be separately positioned on box body and lid two handles 15,16 (can be the most in specie, such as different Two handles of shape) open the lid, thus take out the extrusion infusing pipeline including puncture needle and flap.? After fluid infusion pipeline assembly uses, then puncture needle and flap are put back in puncture needle receiver 1, close box Lid, withholds snap features 14a, 14b is to prevent puncture needle receiver 1 to be opened simultaneously, thus avoids giving up The puncture needle of the fluid infusion pipeline assembly abandoned injure patient or other people.
