Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described in further detail, so that those skilled in the art understand.
Embodiment 1
As shown in Figure 1: a kind of double end precision filter infusion set distinguishing speed governing, the shunting lid 2 comprising dropping funnel 1 and be arranged on dropping funnel 1, shunting lid 2 is arranged side by side the tributary flexible pipe 3 through shunting lid 2, tributary flexible pipe 3 end is provided with air filter 4, air filter 4 end is provided with bottle plug puncture unit 5, and dropping funnel 1 lower end is connected with flow regulator 7, female Luer 8, intravenous needle extension tube 9 and intravenous needle 10 in turn by total tube for transfusion 6; Tributary flexible pipe 3 is provided with arm flow regulator 11.Total tube for transfusion 6 between flow regulator 7 and female Luer 8 is provided with accurate filter 7.
When needs of patients two kinds of liquid input simultaneously, respectively two bottle plug puncture units 5 are inserted infusion bottle, regulate the roller of two flow regulators 11 more respectively, observe a speed of liquid in dropping funnel, two kinds of liquid input two-path liquid simultaneously, arrive tube for transfusion bottom in dropping funnel 1, at dropping funnel 1, place converges, mixed liquid, flows through accurate filter 12 respectively, and female Luer 8, intravenous needle 10 are transported to human vein.Which solve former Dual-head infusion device due to pressure inequality, two groups can not drip simultaneously, or cause pressure large one group of liquid first drips, another group is not dripped, or occurred different problem consuming time due to capacity difference, the bad infusion reaction symptom of patient can be alleviated, and make drug effect better.
Embodiment 2
As shown in Figure 2: the present embodiment is substantially identical with the technical scheme of embodiment 1, and difference is:
Infusion flow adjuster 11 is flow control valve, the profile of flow control valve 11 is in " ear " type, and top one side opening of the flow control valve outside framework of " ear " type, the top frame inwall of flow control valve opening part is provided with row's regulating tooth mouth 11.1.
Infusion flow adjuster 11 is flow control valve, the profile of flow control valve 11 is in " ear " type, and top one side opening of the flow control valve outside framework of " ear " type, flow control valve one end top frame inwall is provided with row's regulating tooth mouth 11.1, flow control valve other end elastic card 11.4 triangular in shape.
When needs of patients two-way liquid inputs simultaneously, respectively two bottle plug puncture units 5 are inserted infusion bottle, the elastic card of adjust flux by-pass cock 11 is stuck on different regulating tooth mouths 11.1 again, thus realizing the different Flow-rate adjustment needed, two kinds of liquid input two-path liquid simultaneously, arrive tube for transfusion bottom in dropping funnel 1, at dropping funnel 1, place converges, mixed liquid, flows through accurate filter 12 respectively, and female Luer 8, intravenous needle 10 are transported to human vein.Solve former Dual-head infusion device and can not regulate flow velocity on arm, and do not reach requirement due to flow velocity, cause injection process uneven, or cause due to capacity difference the problem that both sides can not drip off simultaneously.
Embodiment 3
