Detailed description of the invention:
The application is not limited by following embodiment, can determine specific embodiment according to the technical scheme of the application and practical situation.
As Fig. 1 is to shown in 5, and closed blood sampling transfusion system includes Taper Pipe 1 and bottle cork needle 2 outside venous detaining needle 14, closed transfusion adaptor, Rule；The end of venous detaining needle 14 is provided with fluid injection joint 3, and closed transfusion adaptor includes female end and separation membrane end；Fluid injection joint 3 is connected with the female end of closed transfusion adaptor; the separation membrane end of closed transfusion adaptor mates to seal with the miner diameter end of Taper Pipe outside Rule 1 and is connected; outside Rule, the bigger diameter end of Taper Pipe 1 is connected with bottle cork needle 2, and bottle cork needle 2 fixed sleeves is equipped with puncturing protection set 4.
During blood sampling, fix after venous detaining needle 14 is punctured successfully, the collection blood vial that bottle cork needle 2 inserts sealing starts blood sampling, from the separation membrane end of closed transfusion adaptor, Taper Pipe 1 outside Rule is extracted after blood sampling, then directly transfusion device is connected with the separation membrane end of closed transfusion adaptor, after carrying out liquid washing pipe, starts transfusion.Whole process only needs one-time puncture, simple to operate, and blood sampling, transfusion time are greatly reduced, and is reduced to 1-3 minute from original 5-10 minute, reduces nursing cost, improves work efficiency；For patients such as the old age worked poor, children, promote patient satisfaction, increase treatment enthusiasm, it is to avoid patient causes de-pipe because coordinating time length or worked poor by conditions affect, promotes nursing quality.The cushioning effect of closed transfusion adaptor can effectively control speed of taking a blood sample, it is to avoid the blood sampling haemolysis that causes of excessive velocities and the blood coagulation phenomenon caused the most slowly occur；And owing to closed transfusion adaptor has one-way valve effect, extracting outside Rule after Taper Pipe 1 from closed transfusion adaptor, the effective outflow stoping blood, decrease the space of microbe survival, reduce pollution and the Hematogenous infection of device.Outside closed transfusion adaptor, Rule, Taper Pipe 1, the equal needleless of transfusion device are arranged, and bottle cork needle 2 also has puncture protection set 4 protection, and in blood sampling infusion process, the probability of stabbing of medical personnel is substantially reduced, it is to avoid and reduce occupational exposure risk.Closed transfusion adaptor can use existing public separation membrane Needleless seal transfusion joint, and it uses transparent material, it is simple to observes and assesses blood collection procedure；The smooth easy cleaning of its inner surface, remained blood and medicinal liquid easily wash down.
As shown in Figures 1 to 3, closed transfusion adaptor includes left shell 5, right shell body 6 and glue valve 7；Left shell 5 and right shell body 6 coupling are fixed together and form the cavity 8 of annular hollow, left shell 5 left end is provided with the first nipple 9, fluid injection joint 3 is provided with the first coupling 10, and fluid injection joint 3 is fixedly linked logical by the first nipple 9 with the sealed engagement of mating of the first coupling 10 with left shell 5；Right shell body 6 right-hand member is provided with the second coupling 11；Described glue valve 7 sealing shroud is contained in formation separation membrane end inside cavity 8 right-hand member, and described glue valve 7 center is provided with and coaxially and is under normal conditions in self-enclosed infusion channel 13 with cavity 8, and outside Rule, the miner diameter end coupling sealing shroud of Taper Pipe 1 is contained in infusion channel 13.Outside Rule, the miner diameter end of Taper Pipe 1 can mate the infusion channel 13 inserting glue valve 7 center, forms blood sampling passage；After outside Rule, Taper Pipe 1 is extracted from infusion channel 13, infusion channel 13 return to normal under self-enclosed；Washing pipe, transfusion can be started after transfusion device inserts infusion channel 13.Such without needle construction can reduce medical personnel because of maloperation infected risk；There is not the possibility that rubber blanket chip drops, it is to avoid chip drops in transfusion path, and causes the infection of patient simultaneously.Infusion channel 13 remains to keep self-enclosed after repeated multiple times plug, prevents antibacterial from entering patient fluid infusion's pipeline, it is ensured that patient fluid infusion's safety.
As shown in Figure 2,3, the cross section of glue valve 7 is I-shaped and is installed on inside cavity 8 right-hand member by two terminations, and the right end of glue valve 7 is in the shape that caves inward.So glue valve 7 is fixing reliable, it is simple to repeatedly plugs and does not gets loose；Glue valve 7 right end is easy to Taper Pipe 1 or transfusion device insertion infusion channel 13 outside Rule in the shape that caves inward, it is simple to opening of infusion channel 13.
As shown in Figure 4,5, in " one " font or " ten " font under infusion channel 13 normality.When so Taper Pipe 1 or transfusion device insert infusion channel 13 outside Rule, can evenly extrude infusion channel 13, increase the service life of glue valve 7.
As it is shown in figure 1, the outside of Taper Pipe 1 bigger diameter end is circumferentially uniformly provided with at least four Anti-skid sheet 12 outside Rule.When being inserted into bottle cork needle 2 to collection blood vial, owing to puncturing the setting of protection set 4, needing to overcome bigger resistance, arranging of Anti-skid sheet 12 can increase finger and the frictional force of Taper Pipe 1 outside Rule, it is to avoid finger sliding injury.
Above technical characteristic constitutes the most preferred embodiment of the application, and it has stronger adaptability and optimal implementation result, can increase and decrease inessential technical characteristic according to actual needs, meet the needs of different situations.
