Abstract

The utility model relates to the improvement of an easy-open cap structure for a transfusion bottle, comprising a circular cap whose cap surface is provided with a hole, and an easy-open plug covered on the hole. The easy-open plug is clamped in the hole. The utility model overcomes the problems that the pull ring of an existing easy-open cap for a transfusion bottle can be easily broken, the nurse's hands can be easily hurt when pulling the hole to sterilize, as the punching hole of an aluminium cap is thin, the punching hole can be broken sometimes, and the cap can not be opened, etc. The utility model has the advantages of low cost, simple structure, convenient operation, etc., and the utility model can be widely used for the medical industry.

Description

Easyly opening lid for transfusion bottle

This utility model relates to a kind of improvement of infusion bottle easy-open lid structure.

At present, the Infusion bottle lid of using in the clinical medicine mostly adopts aluminium lid both at home and abroad, in actual use, must use the tamper tool aluminium lid earlier, insert transfusion needle then, because aluminium lid has certain intensity, so effort, time-consuming, the instrument of prying open simultaneously must strict sterilization.The domestic infusion bottle easy-open lid that also has part medical institutions now to use is to make according to the principle of pop can, and this structure has characteristics easy to use than original aluminium lid.But there are more following shortcomings: the one, draw ring is easily broken, produces overlap, the careless slightly hands that easily punctures of nurse's pulling eye sterilization; The 2nd, concave surface is too dark, has amassed dust and has been difficult to handle; The 3rd, the punching of aluminium lid own is too thin, and punching slips off sometimes and makes capping can not draw away.

The purpose of this utility model is to provide a kind of safe, convenient, reliable infusion bottle easy-open lid of operation.

This utility model is made up of capping dome with holes and the Easy-to-pull cork that is covered on the hole, and Easy-to-pull cork is stuck in the hole.

The dome capping is provided with center hole, and center hole is a crimping in the capping; Be covered on the dome cover center circular hole Easy-to-pull cork by draw ring and below have several blades of circular distribution shape the lid body forms, the inner face that the blade circular arc of lid body is formed has circular groove, groove is close to week in the blade, is convenient to mechanization and presses; Draw ring can be same plane with the lid body, and is gapped therebetween, and draw ring girth four minutes has three places to be connected with the lid body, and two relative places connect for point, and another place can guarantee the disposable use of draw ring for section connects, and meets the hygienic practice standard.The draw ring of Easy-to-pull cork also can be located at the lid centre of side on one's body, and covering square centre on one's body has concave surface.

This utility model compared with prior art, have simple in structure, sealing is tight, anti-laying dust, easily sterilization, advantage such as easy to operate; The Easy-to-pull cork that is covered on the dome cover center circular hole can adopt high temperature resistant non-toxic plastic to make, and can save aluminium like this, and the sterilization of nurse's pulling eye is unlikely and punctures hands, and each and every one is easy-to-draw.

Below in conjunction with accompanying drawing embodiment of the present utility model is described.
