Description
Technical field：
The present invention relates to medical infusion equipment technical field, specifically one kind can effectively prevent blood backflow, block up
Fill in the medical infusion forward flow piecing devices in woven hose/hole.
Background technology：
At present, when hospital is transfused liquid to patient, it will usually the infusion attachment device of connector etc is used, in order to
Connection liquid being transported to from a medical instrument between another medical instrument, such as infusion apparatus and remaining needle.Positive pressure is defeated
It is a kind of infusion device of needleless to note attachment device, avoids needle point and punctures the exfoliation pollution liquid generated, while avoid needle
Point accidentally injures medical staff, and connection can generate positive pressure after disconnecting, and avoids generating happening for plugging because of blood back.
Patent document CN 104815363A disclose a kind of positive pressure connector, including needleless joint and rubber plug, rubber plug by
Solid part and hollow part composition, rubber plug is placed in the inner cavity of needleless joint, positive pressure connector access external infusion equipment during use,
External equipment oppresses the upper surface of solid part, the deformation of solid part compression rearward recess, while solid part compressing hollow part is deformed,
External equipment and the unimpeded connection in inner cavity, after external equipment leaves, hollow part rebound.In order to improve the resilience of hollow part,
Above-mentioned document describes and rib is equipped on the outside of hollow part, rib be interruption or horizontal by 70 °, 85 °, 30 ° of angles or be X
Type combines rib, for easily being blocked when solving the problems, such as that hollow part resilience is weak or hollow part is sprung back.
And in fact, the infusion pressure of external equipment direction determine hollow part optimal deformation direction should in hollow part
Axis overlaps, and only hollow part is arranged on when rib is overlapped with hollow part central axes namely rib is straight in above-mentioned technical proposal
When on outer wall, the screen resilience of best results can be obtained, remaining scheme for example rib interruption or rib horizontal by 70 °, 85 °,
During actual loading, screen resilience is disperseed 30 ° of angles by rib, reduces hollow part instead and is smoothly returned along its central axes
The effect of bullet, and interim card easily occurs along rib direction；When rib is straight setting or X-type combination rib, although can obtain
Preferable screen resilience is obtained, but hollow part can be deformed upon and cause obstacle, is caused when external infusion equipment accesses, hollow part is not
Enough deformation can be generated under the effect of external infusion pressure, influence positive pressure effect.
In addition to this, the input terminal of prior art center tap is soft elastic component, is open on elastic component, liquid passes through opening
Input.When in use, when infusion apparatus, which accesses, squeezes elastic component, due to the elasticity of elastic component itself, it can cause to squeeze and not fill
Point, elastic component cannot reduce to greatest extent；And the opening on elastic component, which can be squeezed, to become smaller, and it is obstructed to be easy to cause infusion
The phenomenon that.
