Abstract
The invention belongs to medical instruments field, particularly novel children is with dripping core. Be desirable to provide a kind of novel children with dripping core, can either ensure to meet National Standard of the People's Republic of China does not have again complicated structure, various technique, Risk Reduction. Novel children is made up of inlet, liquid outlet, dropping funnel lid with dripping core. Novel children is disposable injection molded by injection machine with dripping core. Compared with prior art, product appearance is beautiful in the present invention, meets National Standard of the People's Republic of China, and operation design is easy, and safety and sanitation, have reduced artificial pollution, and automaticity is high, and efficiency is high, and risk is little, and running is smooth, has saved human and material resources.
Description
Technical field
The invention belongs to medical instruments field, particularly novel children is with dripping core.
Background technology
In National Standard of the People's Republic of China's disposable infusion set gravity infusion formula (GB8368-2005), dropping funnel and dropper part are done to following requirement: dropping funnel should Continuous Observation drop. Liquid should enter dropping funnel through the dropper of an insertion dropping funnel. The end of dropper to the distance of dropping funnel outlet should be not less than 40mm, or distance between dropper and liquid medicine filter should be not less than 20mm. The distance of dropping funnel wall and dropper terminal should be not less than 5mm. Be that under the condition of (50 ± 10) drip/min, dropper oozes 20 or 60 distilled water and should be (1 ± 0.1) ml{(1 ± 0.1 at (23 ± 2) DEG C, flow velocity) g}. 20 be applicable to adult, 60 be applicable to children. At present, dropping funnel is by drop bottle and drip a core and form, due to children with dropping funnel drip speed require stricter, therefore children formed by inlet (1), dropping funnel lid (2), liquid outlet (3), connector (4), rigidity dropper (5) with a droplet core, as shown in Figure 1. Being connected of dropping funnel lid and connector, connector are all to adopt manual type to bond together at workshop with being connected of rigidity dropper. The children of this kind of structure are with dripping cored structure complexity, and manufacturing process is various, the bonding increased risk that causes of connector and dropping funnel lid, connector and rigidity dropper.
Based on above demand, be desirable to provide a kind of novel children with dripping core, can either ensure to meet National Standard of the People's Republic of China does not have again complicated structure, various technique, Risk Reduction.
Summary of the invention
The technical issues that need to address are: be desirable to provide a kind of novel children with dripping core, can either ensure to meet National Standard of the People's Republic of China does not have again complicated structure, various technique, Risk Reduction.
The present invention adopts following technical proposals to realize: novel children is made up of inlet (1), liquid outlet (3), dropping funnel lid (2) with dripping core. Novel children is disposable injection molded by injection machine with dripping core. Inlet and liquid outlet are in dripping the center position of core, and inlet and liquid outlet are on same vertical axis. The fluid passage length range 19mm-25mm of inlet and liquid outlet composition, liquid outlet tip length scope is that 0.5mm-6mm place is tapered, liquid outlet end internal diameter 0.5mm-0.9mm.
Compared with prior art, product appearance is beautiful in the present invention, meets National Standard of the People's Republic of China, and operation design is easy, and safety and sanitation, have reduced artificial pollution, and automaticity is high, and efficiency is high, and risk is little, and running is smooth, has saved human and material resources.

Detailed description of the invention
As shown in Figure 2, novel children is made up of inlet (1), liquid outlet (3), dropping funnel lid (2) with dripping core. Novel children is disposable injection molded by injection machine with dripping core. Inlet and liquid outlet are in dripping the center position of core, inlet and liquid outlet are on same vertical axis, as shown in Figure 3, the fluid passage length range 19mm-25mm of inlet and liquid outlet composition, liquid outlet tip length scope is that 0.5mm-6mm place is tapered, liquid outlet end internal diameter 0.5mm-0.9mm.
Claims (2)
1. children, with dripping a core, are made up of inlet, liquid outlet, dropping funnel lid, it is characterized in that described children are with dripping core by injection mouldingMachine is disposable injection molded, and the fluid passage length range of inlet and liquid outlet composition is 19mm-25mm, and liquid outlet end is longDegree scope is 0.5mm-6mm, and liquid outlet end is tapered, and described taper is wide at the top and narrow at the bottom and narrows gradually from top to bottom, goes outLiquid mouth end inside diameter ranges is 0.5mm-0.9mm.
2. use and drip a core according to children claimed in claim 1, it is characterized in that, inlet and the liquid outlet center position in a core,Inlet and liquid outlet are on same vertical axis.
