Description
Technical field
This utility model relates to the medicine plug in field of medicaments, particularly a kind of disposable infusion bag medication plug.
Background technology
At present, the transfusion bag in medical field is provided with usually medicine plug and loading plug, loading plug is for connecting transfusion device and transfusion bag.Medicine plug for be injected device pierce through to add in transfusion bag other and transfusion with the use of ancillary drug.In addition, infusion bottle also can arrange bottle stopper, play the effect of medicine plug or loading plug.
In Chinese patent, disclose a kind of medical drugs plug and upper cover thereof, the patent No. is CN2009202231823, disclose in claim 8 and " be provided with in described upper end wall and pull folding hands handle, described folding handle of pulling comprises the root pulled folding part and be connected with the upper surface of upper end wall, the inner side of upper end wall is provided with easy fault trough, described easy fault trough is provided with the inclined plane part that the direction from top to bottom extends radially outwardly, easy dilapidated walls are formed " by described inclined plane part and the described edge line pulling the root of folding handle, therefore, when syringe will be utilized in transfusion bag to inject ancillary drug, repeatedly will certainly pull folding hands handle up and down, easy dilapidated walls are made to send fatigue damage and rupture, thus a hole could be opened so that inject ancillary drug in transfusion bag at upper tops, uncap and require great effort very much, and the rate of uncapping not is very high, in addition, in this patent, as can be seen from Fig. 3 of this patent, upper cover and lower part are fixed together by the form of clamping, this causes turning joins effort, and efficiency of assembling is low.
At present, the plug in the medical drugs plug used in various big hospital is thicker, is sometimes difficult to the injection head of syringe through this plug.Even sometimes, injection head is in the process inserting plug, and the external diameter due to injection head is comparatively large and the area of plug is less, causes plug to be injected head to squeeze in transfusion bag, not only waste medicine, and bring many troubles to the operation of medical worker, therefore, do not promote the use of.In addition, the structure of plug is different form, causes die cost high.
Utility model content
The purpose of this utility model is the shortcoming overcoming prior art, provides that a kind of structure is simple, efficiency of assembling is high, dosing is laborsaving, disposable infusion bag medication plug that low cost of manufacture, sealing are tight.
The purpose of this utility model is achieved through the following technical solutions: a kind of disposable infusion bag medication plug, it comprises upper cover, plug, lower part and pipe, the top surface of described upper cover is provided with through hole, the basal surface of upper cover is provided with two tapered poles, two tapered poles are symmetricly set on the both sides of through hole, the top of described lower part is provided with stepped hole, on the top of lower part and the both sides being positioned at stepped hole are provided with bellmouth, described upper cover is inserted into two bellmouth internal fixtion in lower part respectively through two tapered poles, the top shape spherical in shape of described plug, plug is arranged in stepped hole and plug is pressed between upper cover and lower part, the external diameter of described pipe is less than the diameter of through hole, the vertical setting of pipe, pipe is in turn through through hole and plug, the top of pipe is provided with the masking foil of O-ring pipe orifice, masking foil is arranged in through hole, the top surface of described upper cover is provided with the mucigel covered on through hole, mucigel is bonded with plastic plate, the top of plastic plate is provided with draw ring.
The top of described upper cover is provided with rounding.
This utility model has the following advantages: two tapered poles of (1) upper cover are inserted in bellmouth respectively, thus is fixed in lower part by upper cover fast, and be connected without the need to the form by clamping, efficiency of assembling is very high.(2) spheric end of plug of the present utility model and the basal surface contact area of upper cover little, avoid and interfere, ensure that plug tightly be pressed between upper cover and lower part, increase the sealing of plug, there is the tight feature of sealing.(3) plug of the present utility model is revolving body parts, and structure is simple, reduces the manufacturing cost of mould.(4) when utilizing syringe to add other ancillary drug in transfusion bag, only need first upwards to pull draw ring, draw ring drives plastic plate move upward thus destroyed by mucigel, through hole is exposed, masking foil is destroyed again with the injection head of syringe, ancillary drug can be added by via through holes in transfusion bag, pull folding handle without the need to repeatedly upper and lower, there is dosing labour-saving feature.
