Detailed description of the invention

In order to make of the present utility model to realize technological means, creation characteristic, reach purpose and be easy to understand with effect, under Face combines and is specifically illustrating, and this utility model is expanded on further.

Disclosed in this utility model, a kind of novel infusion container needleless composite cover is arranged on infusion vessel use, defeated Liquid container plays the effect sealing container when storing, for being attached with no-needle transfusion device during use.

Referring in particular to Fig. 1 to Fig. 3, needleless composite cover of the present utility model includes lid 1, needleless joint 2 and pad 3, When typically implementing, the main part of said structure is all cylindric, certainly, in some embodiments, and the main part of said structure Dividing can be polygonized structure.Needleless joint 2 is located at the top of lid 1, and the size of needleless joint 2 is big less than lid 1 bottom Little.This needleless joint 2 is for being connected with no-needle transfusion device, and its periphery is provided with and rotates screw thread accordingly, during use, and this needleless joint 2 are directed at insertion with the connection end of no-needle transfusion device, then rotate clamping.

Pad 3 is formed in one structure, and it is preferably silica gel pad, have good airproof performance, be easily installed, use safety, Free of contamination advantage.So that pad 3 can be compactly installed inside lid 1 and needleless joint 2, the bottom of pad 3 is The first step 31 mated with lid 1 lower shape, top is and the second step 32 of needleless joint 2 form fit, First Rank 31 coupling is flush-mounted in lid 1, and second step 32 coupling is flush-mounted in needleless joint 2.The downside of pad 3 i.e. first step 31 Downside be uncovered, the upside of the pad 3 i.e. top of second step 32 is the mounting 34 being provided with pre-opening 33.This pre-opening 33 is excellent Elect the gap cutting gained on mounting 34 as.When specifically installing, only pad 3 entirety need to be consolidated after the downside of lid 1 is inserted Fixed.In order to be more convenient for installing, pad 3 is preferably provided with transition shoulder 35 between first step 31 and second step 32, this Transition shoulder 35 is so that the insertion installation process of pad 3 is convenient, it addition, the diameter of pad 3 after using said structure Can the gradually transition to top from bottom, more smooth and easy when medicinal liquid circulates wherein.

The top of needleless joint 2 of the present utility model is provided with protruding 4, these protruding 4 generally circular in cross section projections.Weld on protruding 4 Being connected to easily tore film 5, easily tore film 5 coordinates with lid 1, needleless joint 2 and pad 3 can be carried out good sealing.During use, only need Being torn by easily tore film 5, the pre-opening 33 on pad 3 can expose, and is then connected with no-needle transfusion device by composite cover, connection procedure Mounting 34 is carried out extruding and being squeezed by pre-opening 33 by middle no-needle transfusion device, and pad 3 can form infusion channel, in infusion vessel Medicinal liquid can be delivered in no-needle transfusion device by this infusion channel.Whole process is no longer necessary to puncture procedure, and operation obtains Simplify, use convenient, effectively avoid and puncture exfoliation present in piercing process, pad 3 caves in problem, it is ensured that medicine Liquid is the most contaminated, also will not produce infusion hole blocking.

So that the connection between pad 3 and lid 1 is more stable tight, the inner side of lid 1 is provided with plastic strip 6, lid Body 1 is fixed with pad 3 rivet welding by plastic strip 6.During concrete operations, ultrasound wave can be passed to plastic strip 6 He by soldering tip On pad 3, making both composition surfaces because being produced severe friction by ul-trasonic irradiation, both frictional heats composition surface is melted and is completed glue Close.

As it is shown in figure 1, this utility model the most also includes the step cutting pattern 7 for being connected with infusion vessel, it is preferable that two Individual or above composite cover is fixed in side by side on step cutting pattern 7 by the bottom side of lid 1.This structure is installed by step cutting pattern 7 Time on infusion vessel, this infusion vessel is i.e. furnished with two or more composite covers so that single infusion vessel can be with two Or above no-needle transfusion device is attached.

The foregoing is only preferred embodiment of the present utility model, be not limited to this utility model, for this For the technical staff in field, this utility model can have various modifications and variations.All in spirit of the present utility model and principle Within, any modification, equivalent substitution and improvement etc. made, within should be included in protection domain of the present utility model.
