Abstract
The invention discloses a dual connector with threads. The dual connector comprises a base. A medicine mixing passageway and an infusion passageway are arranged on the base. The medicine mixing passageway and the infusion passageway extend out of one end of the base to form medicine mixing connector bodies of the cylindrical hollow structure respectively. A welding portion is arranged at the other end of the base. A tubular protruding portion is arranged at the upper end of each medicine mixing connector body. The inner diameter of the tubular protruding portions is the same as the inner diameter of the medicine mixing connector body. The external threads are arranged on the outer circumferences of the tubular protruding portions. Welding is conducted after the threads are connected with a corresponding outer cover. The process is easy and convenient and easy to operate. A closed thin film is arranged on the upper end face of each tubular protruding portion, and the phenomenon that impurities fall into an infusion bag in the welding process to contaminate medicine is effectively prevented.
Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, particularly relate to a kind of threaded double nip be connected with infusion vessel.
Background technology
In clinical treating disease, often give patient infusion or pass through intravenous drip directly by infusion of medicine body, medicine is often stored in transfusion bag, and the medicinal liquid in transfusion bag injects or output realizes often through hard double nip.
In prior art, double nip comprises pedestal, and pedestal has mixed medicine passage and an infusion channel, mixed medicine passage extends the mixed medicine interface that pedestal forms cylindrical hollow structure, and infusion channel extends the infusion connector that pedestal forms cylindrical hollow structure.
The hard double nip of said structure in use mainly exists following not enough: one, enclosing cover directly welds with double nip, and welding procedure is complicated, not easy to operate; Two, in welding process, have impurity and fall into transfusion bag, pollute medicine.
Summary of the invention
For above shortcomings in prior art, the invention provides a kind of being convenient to and weld, not easily to the threaded double nip that medicinal liquid pollutes.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of threaded double nip, comprise pedestal, described pedestal have mixed medicine passage and an infusion channel, described mixed medicine passage and infusion channel all extend the mixed medicine interface that pedestal respectively forms cylindrical hollow structure from one end of described pedestal, the other end of described pedestal is weld part, described mixed medicine interface upper end is provided with tubulose protuberance, described tubulose protuberance internal diameter is identical with described mixed medicine interface internal diameter, and its excircle is provided with external screw thread.
Further, described tubulose protuberance upper surface is provided with closed thin film.
The invention has the beneficial effects as follows: one, described mixed medicine interface upper end is provided with tubulose protuberance, described tubulose protuberance internal diameter is identical with described mixed medicine interface internal diameter, and its excircle is provided with external screw thread, and screw thread welds after being connected with corresponding enclosing cover again, simple process, is easy to operation; Two, tubulose protuberance upper surface is provided with closed thin film, effectively prevents in welding process, have impurity and falls into transfusion bag, pollutes medicine.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
As shown in Figure 1, the preferred embodiments of the present invention are: a kind of double nip of the welding wing, comprise pedestal 1, described pedestal 1 have mixed medicine passage 2 and an infusion channel 3, described mixed medicine passage 2 and infusion channel 3 all extend the mixed medicine interface 21 that pedestal 1 respectively forms cylindrical hollow structure from one end of described pedestal 1, the other end of described pedestal 1 is weld part 22, described mixed medicine interface 21 upper end is provided with tubulose protuberance 4, described tubulose protuberance 4 internal diameter is identical with described mixed medicine interface 21 internal diameter, its excircle is provided with external screw thread 41; Described tubulose protuberance 4 upper surface is provided with closed thin film 42.
