Description
Technical field
Technical field of medical equipment of the present utility model, is specifically related to a kind of medical sealing structure of simple type.
Background technology
Along with the day by day development of medical skill, the product requirement of armarium class is more and more higher, and most armarium all adopt nontoxic plastic cement to make, and are limited to single use.The drug bag used when infusion uses frequency to be at a relatively high, and its sealing requirements is naturally significantly high.The common practices of hospital is to seal structure (as sealed lid, seal nipple etc.) to drug bag configuration to carry out transfusion operation.Seal nipple usually directly connects in the blank area of drug bag, but existing seal nipple is formed by different assembling parts, processes each part and assembling aspect all relative complex, and sealing effectiveness is poor, can cause secondary pollution simultaneously；And rare integrated seal nipple is also required in process of production by mould open/close twice, production cost is high, and production efficiency is low.
Utility model content
For the deficiencies in the prior art, the purpose of this utility model is in that to provide a kind of medical sealing structure of simple type, and its seal nipple is one-body molded, good sealing effect, and is avoided that secondary assembles the pollution brought.
For achieving the above object, this utility model adopts the following technical scheme that
A kind of medical sealing structure of simple type, including a drug bag with medicine liquid outlet and for sealing the seal nipple of described medicine liquid outlet, seal nipple is one-body molded, the inside of seal nipple is from top to bottom sequentially provided with the medicine liquid channel holding chamber, sealant and connecting with drug bag, sealant is used for isolating accommodation chamber and medicine liquid channel, and the lower end of seal nipple forms connecting portion, the lateral wall of this connecting portion seals with the medial wall of described medicine liquid outlet and coordinates, and the inner side of this connecting portion forms described medicine liquid channel；The lower end outside of connecting portion is provided with Access Division, and connecting portion is inserted in medicine liquid outlet, and this Access Division is arranged on the medial wall of drug bag；The sidewall holding chamber is provided with a breach, holds intracavity and is injection molded with packed layer, and the lateral wall of packed layer seals with the medial wall holding chamber and coordinates, and packed layer has a protuberance being filled in breach.
Preferably, Access Division is wedge shaped.
Preferably, hold and the inwall in chamber offers multiple cannelure.
Preferably, packed layer is thermoplastic elastic material packed layer.
Preferably, the upper end of seal nipple is also sticked for sealing the sealing film setting this packed layer.
The beneficial effects of the utility model are in that:
Compared to prior art, sealing structure of the present utility model, its seal nipple is one-body molded, it is possible to avoid secondary to assemble the pollution brought；The medicine liquid outlet of its connecting portion drug bag seals and coordinates, good sealing effect；Additionally, the accommodation chamber that it is provided with can be used as the die cavity in process of manufacture for sealing-plug molding, can at the interior packed layer being injection molded with sealing-plug effect, and hold the breach offered on chamber and can be used as injection moulding import, avoid twice-die-opening, one-shot forming, saves production cost, improves production efficiency.

Detailed description of the invention
Below, in conjunction with accompanying drawing and detailed description of the invention, this utility model is described further:
The medical sealing structure of a kind of simple type as shown in Figure 1, Figure 2 and shown in Fig. 3, including drug bag 40 and seal nipple 10, this seal nipple 10 is for sealing the medicine liquid outlet of drug bag 40, and seal nipple 10 is one-body molded, injection moulding can be completed in one set of die, without manually assembling again, good sealing effect.
Accommodation chamber 13, sealant 12 and medicine liquid channel 111 from top to bottom it is sequentially provided with in concrete seal nipple 10, and the lower end of seal nipple 10 is formed with a junction 11, it is internal that connecting portion 11 extends downward described drug bag 40, can seal nipple 10 be directly fixed on drug bag 40, and the lateral wall of connecting portion 11 seals with the medial wall of described medicine liquid outlet and coordinates, the medicine liquid outlet of such salable above-mentioned drug bag 40, good sealing effect；Above-mentioned medicine liquid channel 111 is formed at the inside of connecting portion 11 simultaneously, makes this medicine liquid channel 111 connect with drug bag 40, for being derived by medicinal liquid；
In addition, the lower end outside of connecting portion 11 is provided with an Access Division 110, and connecting portion 11 is inserted in medicine liquid outlet, and Access Division 110 is arranged on the medial wall of drug bag 40；Make seal nipple 10 more firm with the annexation of drug bag 40.Certainly, this connecting portion 110 also can adopt hot melting process to seal with medicine liquid outlet, and structure is more firm.Further, Access Division 110 can be wedge shaped, and this wedge-shaped design is conducive to connecting portion 11 to be connected with medicine liquid outlet better seal.
Being injection molded with packed layer 20 holding chamber 13, and the lateral wall of packed layer 20 seals with the medial wall holding chamber 13 and coordinates, so, this packed layer 20 can play the effect of sealing-plug, for drug bag 40 is sealed；Above-mentioned sealant 12 then can intercept accommodation chamber 13 and connect with medicine liquid channel, it is prevented that in use procedure, packed layer 20 directly directly contacts with the medicinal liquid in medicine liquid channel 111, pollutes.
Additionally, the sidewall in above-mentioned accommodation chamber 13 is provided with a breach 131, when injection moulding, first seal nipple 10 is processed by mould, the accommodation chamber 13 that the seal nipple 10 processed has, die cavity can be directly used as, and hold the breach 131 offered on chamber 13 and can be used as injection moulding import, so, when without die sinking, thermoplastic just can enter accommodation chamber 13 through this breach 131 and be shaped to packed layer 20, and this packed layer 20 can play the effect of sealing-plug, avoid twice-die-opening in process of production, one-shot forming, saves production cost, improves production efficiency；And the packed layer 20 processed has a protuberance 21, this protuberance 21 coincide with above-mentioned breach 131 structure, and after packed layer 20 injection formed held in chamber 13, this protuberance 21 can play the effect of sealing.The material of concrete above-mentioned packed layer 20 can be thermoplastic elastomer (TPE), facilitates injection mo(u)lding.
Preferably, in the present embodiment, the inwall in above-mentioned accommodation chamber 13 offers multiple cannelure 132, packed layer 20 bottom face being so molded in this accommodation chamber 13 also has matched groove position, when extracting poke packed layer 20 and sealant 12 successively at fluid-directing needle after, the existence of this cannelure 132 and groove position can effectively prevent dead space capacity leakage in fluid-directing needle, and sealing effectiveness is better.
Preferably, the upper end of seal nipple 10 has also been sticked sealing film 30, and this sealing film 30 sets packed layer 20 for envelope, can prevent extraneous dust from dropping on packed layer 20, can further enhance the sealing of this seal nipple 10.
It will be apparent to those skilled in the art that can technical scheme as described above and design, make other various corresponding changes and deformation, and all these change and deformation all should belong within this utility model scope of the claims.
