Abstract
The utility model relates to a liquid-saving bottle cork puncture in a disposable infusion system; the structure of the part above a needle tip liquid inlet is the same with that of the prior art and is sequentially connected with a needle tip, a cylinder and an air filter; the diameter of the bottom of the needle tip is more than the diameter of the biggest part of the cylinder which is connected with the needle tip; the distance from the bottom end of the liquid inlet on the needle tip to the bottom of the needle tip is 3mm; the length of the cylinder which is connected with the needle tip is shorter than that of the prior art; and the spacing between an air inlet hole and the liquid inlet is reduced to 0.7mm. When an infusion bottle is changed, liquid medicine on the height of 3mm is only left in the bottle, so as to prevent unnecessary medicine waste; and in addition, the stability is improved, so that the puncture is not easy to fall off, and production materials are reduced.
Description
Technical field
This utility model relates to the joint liquid bottle plug puncture unit in the disposable transfusion device, and it can make the big to the greatest extent limit of the medicinal liquid ground output in the infusion bottle, avoids unnecessary medicine waste, has increased stability in addition, and perforator is difficult drop-off more, and has reduced the production material.
Background technology
At present, the bottle plug puncture unit in the known disposable transfusion device has 34mm long to the needle point top more than air filter, is respectively that inlet opening has 8mm long to the needle point top bottom, and the cylinder that inlet opening connects bottom to air filter promptly has 26mm long.The thickness that deducts bottle stopper during transfusion is exactly that bottle plug puncture unit enters the interior height of bottle, the high medicinal liquid of the rarest 16mm can not be exported and remain in the bottle in the infusion bottle when the liquid of being totally lost changes bottle, bottleneck diameter is big more residual many more, formed the medicine waste, in addition, the cylinder of needle point bottom and the cylinder that connects needle point are the same diameters, make that bottle plug puncture unit is oversize and come off sometimes.
Summary of the invention
In order to reduce the waste that bottle plug puncture unit caused in the existing disposable transfusion device and to increase its stability, this utility model provides a kind of joint liquid bottle plug puncture unit, this perforator can not only maximum reduce the medicine waste, and its gravity that can bear is bigger than present, feasible puncture part is difficult drop-off more, and has reduced the material of making perforator.
The technical scheme that its technical problem that solves this utility model adopts is: the needle point of the joint liquid bottle plug puncture unit in disposable transfusion device structure partly is with present the same, but the needle point bottom is a cylinder, inlet on the needle point has the distance of 3mm to the needle point bottom, the big 0.8mm of maximum gauge when the needle point base diameter is connected cylinder than with it, cylindrical length is advisable with 17mm, this perforator in use, it inserts in the bottle partly only is the needle point part, when in infusion process, changing bottle, the high medicinal liquid of its only residual naturally 3mm, thereby greatly reduce the waste of medicine, because the needle point base diameter is connected cylindrical maximum gauge than with it big, so increased degree of stability, shortened because of overall length so save material in addition.
The beneficial effects of the utility model are: when transfusion is changed bottle each time, make the high medicinal liquid of only residual naturally 3mm in the bottle, greatly reduce the waste of medicine; Increased degree of stability in addition, the perforator part is difficult drop-off more; And reduced the material of making perforator, the end is mentioned partly with original the same, simple in structure.

Concrete embodiment
The technical scheme that its technical problem that solves this utility model adopts is: the inlet of the joint liquid bottle plug puncture unit in the disposable transfusion device with the shape of upper part with present the same.The perforator total length has reduced 6mm, the needle point bottom is a cylinder, diameter of a circle is 5.2mm, inlet on the needle point has the distance of 3mm bottom to the needle point bottom, the needle point base diameter is connected the long 0.8mm of cylindrical diameter than with it, the needle point bottom is two concentric circulars with being connected cylindrical profile, the diameter of cylinder the inside air inlet and inlet opening is with present the same, but being reduced to, the spacing of air inlet and inlet opening has only 0.7mm, cylindrical outward flange reduces to 0.7mm to the weakness of the spacing of air inlet and inlet opening, and cylindrical length is advisable with 17mm.When this perforator uses in transfusion, its insert in the bottle only is needle point partly, when in infusion process, changing bottle, the high medicinal liquid of its only residual 3mm, thereby greatly reduce the waste of medicine, puncture difficult drop-off and reduced the material of making perforator more partly in addition.
Claims (3)
1. the joint liquid bottle plug puncture unit in the disposable transfusion device, be linked in sequence by needle point, cylinder, air filter, it is characterized in that: the inlet opening on the big 0.8mm needle point of cylindrical diameter that the diameter of its needle point bottom is connected than with it is 3mm to the vertical distance of cylinder that connects, cylindrical length 17mm.
