Description
Technical field
Technical field of medical equipment of the present utility model, is specifically related to a kind of medical hermetically-sealed construction.
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 adopts nontoxic plastic cement to make, and is restricted to single use.The drug bag frequency of utilization used when infusion is quite high, and its sealing requirements is naturally very high.The common practices of hospital carries out transfusion operation to drug bag configuration hermetically-sealed construction.And existingly generally all comprise a Connection Block be connected with drug bag and a sealing-plug for processing this hermetically-sealed construction for drug bag, and the technique of processing described Connection Block and sealing-plug is all need separately be processed by mould usually, then assemble, so can cause secondary pollution; And before rare by sealing-plug and Connection Block one-body molded, but it also needs in process of production by mould open/close twice, and 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 to provide a kind of medical hermetically-sealed construction, and it has integrated seal cover, avoids secondary to assemble the pollution brought, saves production cost.
For achieving the above object, this utility model adopts following technical scheme:
A kind of medical hermetically-sealed construction, comprise integrated seal cover, the inside of sealing lid is provided with medicine liquid channel, sealant and container cavity from the bottom to top successively, and sealant is for isolating medicine liquid channel and container cavity; The lower end of medicine liquid channel has medicinal liquid import; The sidewall of container cavity is provided with a breach, and in container cavity, injection mo(u)lding has packed layer, and the medial wall of the lateral wall of packed layer and container cavity is sealed and matched, and packed layer has one and is filled in protuberance in breach.
Preferably, the end face of packed layer is provided with needle pierces hole.
Preferably, sealing covers end and is also sticked for sealing the sealing film establishing this packed layer.
Preferably, the sealing film part protruded from outside seal cover forms a tear film hands position.
Preferably, sealing structure also comprises a drug bag, and seal cover and outside drug bag are tightly connected in a welding manner; Medicinal liquid import is communicated with described drug bag.
Preferably, packed layer is thermoplastic elastic material packed layer.
The beneficial effects of the utility model are:
Compared to prior art, medical hermetically-sealed construction of the present utility model, its seal cover is one-body molded, and secondary can be avoided to assemble the pollution brought; In addition, its container cavity be provided with can be used as the die cavity for sealing-plug molding in process of manufacture, the packed layer of sealing-plug effect can have been had in interior injection mo(u)lding, and the breach that container cavity is offered can be used as injection moulding import, avoid twice-die-opening, one-shot forming, saves production cost, and enhances productivity.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the partial structurtes schematic diagram of seal cover of the present utility model;
Fig. 3 is the structural representation of packed layer of the present utility model.
Wherein, 10, Connection Block; 11, medicine liquid channel; 12, container cavity; 121, breach; 13, diaphragm seal; 20, packed layer; 21, needle pierces hole; 22, protuberance; 30, sealing film; 31, tear film hands position.
Detailed description of the invention
Below, by reference to the accompanying drawings and detailed description of the invention, this utility model is described further:
The medical hermetically-sealed construction of one as shown in Figure 1, Figure 2 and shown in Fig. 3, comprises seal cover 10, and sealing lid 10 is one-body molded, injection moulding can be completed in one set of die, being equivalent to Connection Block of the prior art and sealing-plug one-shot forming, without the need to manually assembling again, and assembling reliable non-loosening.
The inside of concrete sealing lid 10 is provided with medicine liquid channel 11, sealant 13 and container cavity 12 from the bottom to top successively, and the lower end of medicine liquid channel 11 has medicinal liquid import, for guiding medicinal liquid; Have packed layer 20 in container cavity 12 injection mo(u)lding, and the medial wall of the lateral wall of packed layer 20 and container cavity 12 is sealed and matched, so, this packed layer 20 can play the effect of sealing-plug, for sealing drug bag; And above-mentioned sealant 13 can be used for the diaphragm seal 13 that obstruct container cavity 12 is communicated with medicine liquid outlet, prevent packed layer 20 in use procedure from directly directly contacting with the medicinal liquid in medicine liquid channel 11, pollute.
In addition, the sidewall of container cavity 12 is provided with a breach 121, when injection moulding, is first processed by seal cover 10 by mould, the container cavity 12 that the seal cover 10 processed has, directly can be used as the die cavity of sealing-plug, and the breach 121 that container cavity 12 is offered can be used as injection moulding import, be shaped to packed layer 20 when just container cavity 12 can be entered through this breach 121 without the need to thermoplastic when die sinking, avoid twice-die-opening in process of production, one-shot forming, saves production cost, and enhances productivity; The packed layer 20 so processed has a protuberance 22, and this protuberance 22 coincide with above-mentioned breach 121 structure, and after packed layer 20 injection formed in container cavity 12, this protuberance 22 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.
When using above-mentioned hermetically-sealed construction, seal cover 10 is connected with the drug bag that medicinal liquid is housed, and the coupling part on the mode of welding and drug bag specifically can be adopted to be sealed and matched, for sealing the medicinal liquid in drug bag.And the import of above-mentioned medicine medicinal liquid is communicated with described drug bag, for entering medicine; In addition, needle pierces hole 21 can be provided with at the end face of packed layer 20, facilitate fluid-directing needle to poke packed layer 20 and diaphragm seal 13 successively, thus with medicine liquid outlet conducting, medicinal liquid is derived.
Preferably, the upper end of above-mentioned seal cover 10 has also been sticked sealing film 30, and sealing thin film 30 establishes packed layer 20 for envelope, can prevent extraneous dust from dropping on packed layer 20, can strengthen the sealing of sealing structure further.Further, sealing thin film 30 part protruded from outside seal cover 10 can form a tear film hands position 31, and thin film is torn by person easy to use.
To one skilled in the art, according to technical scheme described above and design, other various corresponding change and deformation can be made, and all these change and deformation all should belong within the protection domain of this utility model claim.
