Abstract
The utility model relates to a rubber plug for medicinal use, which has a rubber plug body. The rubber plug body consists of an upper part and a lower part which are connected with each other. The rubber plug for medicinal use is made of two materials, thereby partly breaking away from the dependence on butyl rubber, and reducing the cost. One of the two materials is butyl rubber, whichthereby meetsing the regulations set by the state national administrative departments in charge of medicines. The rubber plug for medicinal use does not need siliconizing and puts an end to the 'phenomenon of hanging onto a wall'; and the two materials are firmly and reliably connected with each other in the mode of chemical crosslinking, and the connection is firm and reliable.
Description
Technical field
This utility model relates to a kind of sealed piece of containers for medical use, particularly a kind of medical rubber plug.
Background technology
Medical rubber plug is the main sealed piece of bottled medicine, present widely used medical rubber plug comprise superposed plug hat and be positioned at plug hat bottom and connected plug neck, to fill in neck during use is pressed in the bottleneck, the plug hat is pressed in the bottleneck end, utilize the distinctive elasticity of rubber, reach the effect of sealing medicine, for the storage and the use of medicine are provided convenience.In order to guarantee drug safety, national medical authorities stipulate that domestic all medical rubber stoppers of beginning were stopped using common natural gum bottle stopper without exception in 2005, and what replace common natural gum bottle stopper is butyl rubber plug.Butyl rubber is elastomeric a kind of, and is synthetic by isobutene. and a small amount of isoprene, is characterized in good, heat-resisting, the anti-ozone of air-tightness, ageing-resistant, chemical-resistant resistance.Yet the enterprise that produces medical rubber plug at present is for the ease of packing and tamponade, and the mantle friction in the minimizing transportation handling process, avoids because of friction causes the buffings microgranule, all can carry out silicidation after sulfuration, flash trimming and cleaning.Yet with after medicated powder contact, medicated powder is easy to and can be adsorbed by silicone oil, forms colloid or medicated powder group through the medical rubber plug after the silicidation, and the plug contact area is big, and formed colloid or medicated powder group are also just many.Medicine dilution back is water insoluble because of silicone oil itself, so will produce muddy and medicated powder indissoluble phenomenon; Secondly, infusion products generally all can pass through high temperature sterilize, is cooled to room temperature then, because silicone oil molecular thermalmotion when high temperature aggravates, invests after the silicone oil on plug surface comes off on bottle wall and forms " wall built-up " phenomenon.In addition because the price of Butyl Rubber Closure in Medical Field is comparatively expensive, so the production cost of medical rubber plug is also higher relatively at present.
The utility model content
The purpose of this utility model is to provide a kind of does not need silicidation, and the relatively low medical rubber plug of cost.
The technical scheme that realizes this utility model purpose is: the utlity model has rubber plug body; Described rubber plug body is formed by connecting up and down by two parts.
The rubber plug body of above-mentioned medical rubber plug has plug and labels portion, plug hat bottom and the plug neck that is connected with plug hat lower end, bottom, two-part one of them part of described composition rubber plug body is labeled portion for plug, and another part is plug hat bottom and the plug neck that is connected with plug hat lower end, bottom.
The rubber plug body of above-mentioned medical rubber plug has plug and labels portion, plug hat bottom and the plug neck that is connected with plug hat lower end, bottom, two-part one of them part of described composition rubber plug body is labeled portion and plug hat bottom for plug, the plug neck of another part for being connected with plug hat lower end, bottom.
Connection between two parts of the rubber plug body of above-mentioned medical rubber plug is that chemical crosslinking connects.
One of them part main material of two parts of the rubber plug body of above-mentioned medical rubber plug is halogenated butyl rubber or common butyl rubber or synthetic rubber, and the main material of another part is thermoplastic elastomer (TPE) or plastics or synthetic rubber.
The utlity model has following characteristics:
(1) the present invention adopts two kinds of material be combined intos, thereby part has been broken away from the dependence to butyl rubber, has reduced cost;
(2) a kind of butyl rubber that is is arranged in two kinds of materials of the present invention, meet national medical authorities regulation.
(3) medical rubber plug of the present invention need not silicidation, " wall built-up " phenomenon can not occur;
(4) adopt the mode of chemical crosslinking to connect firm and reliable connection between two kinds of materials of the present invention.
Description of drawings
