Abstract
The utility model discloses a rubber plug used for injection, comprising a top cover, and an inside sealing part and an outside sealing part which are connected on the top cover; wherein a bottleneck part of an injection bottle extends to the position between the inside sealing part and the outside sealing part. The rubber plug of the utility model is additionally provided with one sealing part on the basis of the existing rubber plug, i.e., the top cover of the existing rubber plug used for injection is only provided with one sealing part, while the rubber plug of the utility model is provided with the inside sealing part and the outside sealing part. When the rubber plug is in use, the bottleneck part of the injection bottle extends to the position between the inside sealing part and the outside sealing part for performing sealing, so that the rubber plug has a good sealing performance, even if a slight liquid leakage phenomenon occurs on the bottle, the leaked liquid can flow into a sealing cavity between the inside sealing part and the outside sealing part, and cannot flow out of the injection bottle to cause pain of a patient, thereby reducing the risk of liquid leakage, in addition, the rubber plug of the utility model enables a medical worker to clearly identify an injection port and an exhaust port during the process of injection, thereby raising work efficiency of the medical worker.
Description
Technical field
This utility model relates to plug technical field, particularly relates to a kind of injection plug.
Background technology
The inherent cleanliness factor of butyl rubber bottle stopper, chemical stability, air-tightness, biological property are all fine, but because of fill a prescription complexity and add the relation of raw material Concentraton gradient, after the more intense drug pack of some molecular activities, by drug absorption, absorption, leaching, infiltration, produced the consistency problem of plug and medicine, relatively more outstanding is part cephalosporins, part infusion solutions class and more Chinese medicine injection liquid formulation etc.So by selecting the soft coating of a kind of inertia, cover plug surface, isolation medicine contacts with the direct of bottle closure of rubber, can obviously improve like this compatibility with medicine.Country to all medical rubber plugs (comprising each dosage form plugs such as transfusion, oral liquid) before the end of the year 2004 are stopped using Ordinary natural rubber stoppers without exception; The medicine rubber stopper in all pharmaceutical factories all will use butyl rubber plug.
But, butyl rubber bung is in the process of promoting the use of, the subject matter running into is: fragmentation, leakage, the problems such as wall built-up, along with industry formula and the processing technique of butyl rubber stoppers reach its maturity, fragmentation and wall built-up problem have obtained good solution, but adopt the seal rubber plug of original plug structure, also there will be once in a while the phenomenon of leakage, thereby cause the patient's of injecting fluid pain and uncomfortable phenomenon, trace it to its cause, because the sealing property deficiency of plug causes, in addition, existing injection butyl rubber bung, above it without distinctive mark, be not easy to just enter a profession or unskilled medical personnel use, when use, also need to inquire injection mouth and the air vent of just knowing plug everywhere, it is not very convenient using.
Utility model content
In order to overcome above-mentioned the deficiencies in the prior art, this utility model provides a kind of injection plug, its object is to improve the sealing property of existing plug, thereby avoids the phenomenon of leakage of injection in the time of injection, removes pain and uncomfortable phenomenon that transfusion patient causes due to leakage from.
The technical scheme that this utility model adopts is: a kind of injection plug, comprise top cover, plug also comprises the interior sealing being connected on top cover, outer seal portion, the bottleneck portion of injection bottle stretches between interior sealing and outer seal portion, the wall thickness of outer seal portion is less than or equal to the wall thickness of interior sealing, make plug there is higher sealing property, plug of the present utility model, on the basis of existing plug, be provided with sealing one more, that is to say existing injection plug, on its top cover, be only provided with one sealing, and this utility model is provided with interior sealing and outer seal portion, when use, the bottleneck portion of injection bottle is stretched between interior sealing and outer seal portion and sealed, make plug there is good sealing property, even if there is the slight phenomenon of leakage in bottle, leakage also can flow in the annular seal space between interior sealing and outer seal portion, can not flow out injection bottle, cause Principle of Pain, reduce the risk of leakage.
Further, in order to adapt to the shape of injection bottle, top cover is circular, and interior sealing and outer seal portion are cylindricality.
Again further, be also provided with inlet opening and steam vent on top cover, inlet opening is counter sink, and steam vent is bellmouth, thereby has alleviated the dynamics of voluntary labor service author in the time of acupuncture injection bottle, and alleviates bits.
In addition, inlet opening one side is also provided with feed liquor label, and steam vent one side is also provided with aerofluxus label, so that medical personnel energy cheer and bright ground identification injection mouth and air vent in the time of injection are increased work efficiency.
Above the top cover of plug, be also provided with equably some projections; so that when acupuncture; can just can sting the aluminum protecting film that comes unglued and comprise beyond the Great Wall with less dynamics; and on the inward flange of outer seal portion, be also provided with screw thread; so that and the threaded engagement of injection bottle, thereby the sealing property of increase injection bottle.The bottom of top cover is also provided with some mastoid processes, the shape of mastoid process can be rule or irregular shape, and as semicircle, box-shaped, taper shape, or other irregularly shapedly all can, to slow down the speed of leakage, alleviate pain and uncomfortable sensation that transfusion patient causes due to leakage.
Compared with prior art, the beneficial effects of the utility model are: plug of the present utility model, on the basis of existing plug, be provided with sealing one more, that is to say existing injection plug, on its top cover, be only provided with one sealing, and this utility model is provided with interior sealing and outer seal portion, when use, the bottleneck portion of injection bottle is stretched between interior sealing and outer seal portion and sealed, make plug there is good sealing property, even if there is the slight phenomenon of leakage in bottle, leakage also can flow in the annular seal space between interior sealing and outer seal portion, can not flow out injection bottle, cause Principle of Pain, reduce the risk of leakage.
Phenomenon of leakage when this utility model has avoided plug for injection bottle, the discomfort while having reduced patient's leakage, and make the medical personnel can cheer and bright ground identification injection mouth and air vent in the time of injection, improve medical personnel's work efficiency.
