Abstract
The utility model discloses an interface-sealing device used for a soft infusion bag, which solves the problem that the sealing quality of the prior soft infusion bag is hard to control, and has the advantages of simple structure, convenient use and elimination of the potential safety hazard. The utility model consists of an easy-open end, a sealing rubber plug and a connecting body. A through hole is arranged in the connecting body. One end of the connecting body is a clamping interface, which is firmly rabbeted with the sealing rubber plug and the easy-open end to form a clamping embedded-connection sealing structure, the other interface of the connecting body is sealed and connected with the infusion bag. A lined ring which is coordinated with the easy-open end is arranged on the connecting body.
Description
Technical field
This utility model relates to a kind of sealing joint device, particularly a kind of transfusion flexible bag interface sealing device.
Background technology
Present America and Europe and developed country are used for being tightly connected of transfusion flexible bag and generally include: be plugged on the plug on the transfusion flexible bag mouth pipe, loaded onto plug at the plug top, put aluminium alloy cap seal mouth, it is in light weight, transportation, use easy to carry, open aluminium alloy lid hole during use, insert transfusion device and derive medicinal liquid, automatic retraction does not need air inlet during transfusion.Its design is easy to use, thereby has obtained extensive use.
The shortcoming of this structure is to need aluminium alloy lid distortion closing in compression plug to reach sealing effectiveness at seal process, and aluminium alloy covers in seal process because of the distortion friction of closing up produces aluminum bits, microgranule, is difficult to this deadly defect of control of quality, also exists the high complex structure and other problems of cost simultaneously.Thereby the further deeper popularization that has influenced soft bag infusion develops.
Therefore the needs design is a kind of can eliminate above-mentioned hidden danger fully, and single between structure, easy to operate sealing joint device.Chinese patent 2005200856935 has provided a kind of non-PVC-soft-bag transfusion dosing connection tube flap, and it adopts plastic union pipe, and rubber stopper is set in the mouth of pipe reaches the lid that is connected with the mouth of pipe, be elastic closure flat pipe at the hypomere of plastic union pipe.This structure has solved the problems referred to above to a certain extent, but it also exists lid and mouth of pipe junction poorly sealed, easily comes off, to use problem such as make troubles.
Summary of the invention
The technical problems to be solved in the utility model is to solve the foreign material that produce in the present seal process makes airtight quality be difficult to control, product is poorly sealed, be prone to problem such as come off, provide a kind of have simple in structure, easy to use, can eliminate the transfusion flexible bag interface sealing device of advantages such as above-mentioned potential safety hazard.
For achieving the above object, this utility model is by the following technical solutions:
A kind of transfusion flexible bag interface sealing device, it is made up of easy-open end, sealing plug, connector, and consistent reach through hole is arranged in the connector, and connector one end is the plug-in port, this port is closely rabbeted with sealing plug and easy-open end, forms cassette and embeds the connection hermetically-sealed construction; Connector another port and transfusion bag are tightly connected, and described connector top is provided with the grommet that matches with easy-open end.
Described easy-open end is the medicated cap shape, and inner hollow has easy opened handle on its top cover, and there is at least one groove at its waistline place.
Described sealing plug is a T shape, its underpart hollow, and the center, top is the concave arc sphere, is provided with bulge loop in the periphery that seals plug, and the bulge loop downside is a crown, and what seal plug is cervical vertebra bottom, and the cervical vertebra excircle is the conical surface.
Described grommet is in the boss inboard of connector upper port; The connector lower port is a rhombus, with the transfusion bag welded seal.
This utility model on the basis of existing technology, be provided with grommet on connector top, it cooperates with easy-open end, can strengthen sealing, strengthen connection power, the accident that prevents easy-open end breaks away from, improved the safety of medication, the whole particular design that adopts the cassette down to go into to connect of this utility model, utilize the liner baffle ring structure in the connected body upper port to cooperate with T pattern sealing plug, T type sealing rubber plug bizet cervical region makes its formation interference fit reach sealing with the easy-open end that the interior liner baffle ring mutual dependence for existence in connected body upper end goes into to have groove at down respectively.Also avoided simultaneously phenomenon such as leakage and Tuo Gai under specific condition.Plug top concave ball shape is the acupuncture position, operates the smooth and easy puncture center of finding accurately for making things convenient for medical personnel.Because the connection place of body and soft bag is thin-walled, the soft bag transfusion package product that circulates on the present relatively market is material-saving more, thereby has reduced cost.
The beneficial effects of the utility model are: adopt juncture to go into to connect for the cassette down, thereby avoided because of aluminium alloy distortion friction produce aluminum bits, microgranule and lid and mouth of pipe junction poorly sealed, defective such as easily come off.
Description of drawings
Fig. 1 is this utility model assembly structure sketch map;
Fig. 2 is described fractionation parts master cutaway view.
Wherein, 1. easy-open end 2. seals plug, 3. connector, 4. grommet, 5. crown, 6. cervical vertebra, 7. boss.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and embodiment.
Among Fig. 1, Fig. 2, this utility model transfusion flexible bag interface sealing device is made up of easy-open end 1, plug 2, connector 3.Easy-open end 1 is for having easy opened handle, its waistline place fluted on cap shaped, hollow, the top cover.The similar T shape of plug 2 type shapes, bottom hollow, center, top are the concave arc sphere, comprise crown 5 and cervical vertebra 6 that cervical vertebra 6 excircles have certain conical surface.
Easy-open end 1 is made by the polyolefine material that meets national medical regulation with connected body 3, and plug 2 is made by the rubber that meets national medical regulation.
Assembling process of the present utility model: easy-open end 1 is combined into one, embeds in connected body 3 cassette interfaces with plug 2 and engages.
Go into the reliability of concavo-convex recessed bayonet socket in order to increase down; it is that grommet 4 is protected that this utility model has designed interior Liner Seal Ring; embed boss 7 positions of connector 3 when the groove of easy-open end 1; the outer shroud of described grommet 4 and easy-open end 1 hollow wall cooperatively interact; the inner ring surface of grommet 4 and the cervical vertebra of plug are combined closely, and rely on protection to make camphane go into the formula bayonet socket under the effect that is subjected to external force mutually any variation does not take place.
When easy-open end 1 presses down, simultaneously the inwall of grommet 5 is subjected to plug 2 extruding force effects simultaneously, the cervical vertebra diameter increases gradually, thereby reaches cervical vertebra 6 and grommet inwall interference fit, has increased the sealing that down is gone into the back inwall.
When easy-open end 1 presses down, plug crown 5 is subjected to the power supporting role distortion of top, grommet 4 top to reach crown 5 and grommet 4 sealings.
Closely cooperate and locked the probability of easy-open end 1 groove slippage connector 3 boss 7 simultaneously when easy-open end 1 presses down its hollow wall and grommet 4 outer walls.
Using method of the present utility model
Open the easy opened handle of easy-open end 1, the site of puncture of plug 2 is just exposed, and with the transfusion apparatus derivation medicinal liquid that punctures, automatic retraction does not need air inlet during transfusion.
