Description
Technical field
This utility model relates to transfusion bag joint, particularly a kind of cap-rotating type transfusion bag joint.
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; the cap-rotating type transfusion bag joint providing a kind of structure simple, easy to use, this device sealing is good, reliable clamping, can not polluted and can not produce the rubbish such as dyestripping or draw ring by available protecting medicinal liquid.
The purpose of this utility model is achieved through the following technical solutions: a kind of cap-rotating type transfusion bag joint, it comprises welding base, tube for transfusion and seal cover, 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, pilot hole is had in sealing ring, seal cover is arranged on tube for transfusion, seal cover is provided with pressing plate and rotating shaft bottom outlet, by rotating shaft, rotation cover is installed between seal cover and pressing plate, rotation cover has rotating shaft through hole with rotating shaft corresponding position.
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.
Described rotating shaft is by matched in clearance through rotating shaft through hole, and rotating shaft is arranged in rotating shaft bottom outlet by interference fit.
Described rotation cover is arranged between seal cover and pressing plate by interference fits.
This utility model has the following advantages: this utility model structure is simple, easy to use, penetration Resistance can be reduced by arranging conical pilot hole, avoid producing residue, medical personnel are facilitated to operate, and reliable clamping, sealing are good, making can not produce leakage during transfusion, can not produce as the rubbish such as dyestripping or draw ring by adopting rotary cover plate.

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 cap-rotating type transfusion bag joint, it comprises welding base 1, tube for transfusion 2 and seal cover 4, tube for transfusion 2 is arranged on above welding base 1, in the present embodiment, described welding base 1 is rounded diamond, several grooves 9 are had at four sides, welding base 1 is provided with ladder hole 10 with tube for transfusion 2 junction, sealing ring 3 is installed in the macropore of ladder hole 10, in the present embodiment, described sealing ring 3 is arranged on by interference fit in the macropore of ladder hole 10, pilot hole 6 is had in sealing ring 3, described pilot hole 6 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, seal cover 4 is arranged on tube for transfusion 2, seal cover 4 is provided with pressing plate 5 and rotating shaft bottom outlet 12, by rotating shaft 7, rotation cover 8 is installed between seal cover 4 and pressing plate 5, in the present embodiment, described rotation cover 8 is arranged between seal cover 4 and pressing plate 5 by interference fits, rotation cover 8 has rotating shaft through hole 11 with rotating shaft 7 corresponding position, in the present embodiment, described rotating shaft 7 passes rotating shaft through hole 11 by matched in clearance, rotating shaft 7 is arranged in rotating shaft bottom outlet 12 by interference fit.
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 9 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, rotation cover 8 is exerted a force, it is made to rotate to expose pilot hole 6 around rotating shaft 7, tube for transfusion syringe needle is thrust sealing ring 3 by pilot hole 6 and pierces through, due to pilot hole 6 is set and pilot hole 6 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 10 macropore by interference fit and the outside diameter of pilot hole 6 be greater than the diameter of tube for transfusion syringe needle, the diameter that central diameter is less than tube for transfusion syringe needle can ensure reliable clamping, sealing ring 3 and tube for transfusion syringe needle can not drop.
