Abstract
The utility model discloses a kind of highly reliable infusion bag opener, it comprises welding base (1) and tube for transfusion (2), tube for transfusion (2) is arranged on welding base (1) top, welding base (1) and tube for transfusion (2) junction are provided with ladder hole (6), sealing ring (3) is installed in the macropore of ladder hole (6), in sealing ring (3), has pilot hole (4).The beneficial effects of the utility model are: this device has that structure is simple, sealing is good, medicinal liquid can be protected not to be subject to polluting, puncture is without advantages such as residue generation, reliable clamping, easy to operate and penetration Resistance are little.
Description
Technical field
This utility model relates to infusion bag opener, particularly a kind of highly reliable infusion bag opener.
Background technology
Transfusion bag is by bag and infusion bag opener are welded together to form an entirety, in welding process, by the restriction of joint geometry or welding procedure, may cause be welded with residue and residual stay in transfusion bag or welded seal poor.In use, medical personnel need to be thrust in transfusion bag by transfusion needle and liquid could be derived, under existing technical conditions, the mouth of pipe majority of tube for transfusion is equipped with aluminium-plastic combined cover, then need aluminum material to tear before using, syringe needle could be thrust in plastic plug, but aluminum material may tear and causes producing irregular opening in the process of tearing, easy scuffing medical personnel, also can produce some plastic residues and be mixed in medicinal liquid and pollute medicinal liquid when punctures plastic plug.
Utility model content
The purpose of this utility model is the shortcoming overcoming prior art, provides the highly reliable infusion bag opener that a kind of structure is simple, easy to use, and this device sealing is good, reliable clamping, can not polluted by available protecting medicinal liquid.
The purpose of this utility model is achieved through the following technical solutions: a kind of highly reliable infusion bag opener, it comprises welding base and tube for transfusion, tube for transfusion is arranged on above welding base, welding base and tube for transfusion junction are provided with ladder hole, in the macropore of ladder hole, sealing ring is installed, in sealing ring, has pilot hole.
Described welding base is rounded diamond, has several grooves at four sides.
Described sealing ring is arranged in the macropore of ladder hole by interference fit.
Described pilot hole is tapered blind hole, and its outside diameter is greater than the diameter of tube for transfusion syringe needle, and its central diameter is less than the diameter of tube for transfusion syringe needle.
This utility model has the following advantages: this utility model structure is simple, easy to use, can penetration Resistance be reduced by arranging conical pilot hole, avoiding producing residue, facilitating medical personnel to operate, and reliable clamping, sealing are good, make can not produce leakage during transfusion.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of highly reliable infusion bag opener.
In figure, 1-welds base, 2-tube for transfusion, 3-sealing ring, 4-pilot hole 5-groove, 6-ladder hole.
Detailed description of the invention
Be further described this utility model below in conjunction with accompanying drawing, protection domain of the present utility model is not limited to the following stated:
As shown in Figure 1, a kind of highly reliable infusion bag opener, it comprises welding base 1 and tube for transfusion 2, in the present embodiment, described welding base 1 is rounded diamond, several grooves 5 are had at four sides, tube for transfusion 2 is arranged on above welding base 1, welding base 1 is provided with ladder hole 6 with tube for transfusion 2 junction, sealing ring 3 is installed in the macropore of ladder hole 6, in the present embodiment, described sealing ring 3 is arranged on by interference fit in the macropore of ladder hole 6, pilot hole 4 is had in sealing ring 3, in the present embodiment, described pilot hole 4 is tapered blind hole, its outside diameter is greater than the diameter of tube for transfusion syringe needle, its central diameter is less than the diameter of tube for transfusion syringe needle.
Work process of the present utility model is as follows: coordinated with transfusion bag by welding base 1 and weld together, the welding base 1 of rounded diamond shape can make welding base 1 contact with transfusion bag well, groove 5 can reduce welding base 1 and the contact area of transfusion bag, avoids transfusion bag because causing failure welding too greatly by heat transition contraction or solder side thus affect sealing.
During use, infusion bag opener is placed upward, tube for transfusion syringe needle is thrust sealing ring 3 by pilot hole 4 and pierces through, due to pilot hole 4 is set and pilot hole 4 base wall thin can effectively reduce penetration Resistance and avoid producing residue be mixed into medicinal liquid medicinal liquid polluted, due in sealing ring 3 to be arranged on ladder hole 6 macropore by interference fit and the diameter that the outside diameter of pilot hole 4 is greater than the diameter of tube for transfusion syringe needle, central diameter is less than tube for transfusion syringe needle can ensure that reliable clamping, sealing ring and tube for transfusion syringe needle can not drop.
Tube for transfusion 2 can arrange any type of sealing device or protector, do not polluted to protect pilot hole 4.
