Description
Technical field
It is specifically a kind of when it is connected to one the present invention relates to the field of medical instrument technology being transfused for liquid
During medical instrument, the circulation of liquid, when being disconnected with upstream medical instrument, liquid can be carried out between another medical instrument
The positive pressure threeway for producing the forward flow to outlet and downstream medical instrument direction is transfused attachment device.
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 transfusion device 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 produced, while avoids pin
Point accidentally injures medical staff, and connection can produce positive pressure after disconnecting, and the situation for avoiding producing plugging because of blood back occurs.
Patent document CN 104815363A disclose a kind of positive pressure connector, it includes 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, which describes, is equipped with rib on the outside of hollow part, rib be interrupted or horizontal by 70 °, 85 °, 30 ° of angles or be X
Type combines rib, and for solving the problems, such as that hollow part resilience is weak or hollow part is sprung back when easily blocks.
And in fact, the infusion pressure of external equipment direction determine hollow part optimal deformation direction should with hollow part
Axis overlaps, and only when rib is overlapped with hollow part central axes in above-mentioned technical proposal, namely rib is straight is arranged on hollow part
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, its screen resilience is disperseed 30 ° of angles by rib, reduces hollow part on the contrary 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 combines 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 produced under the effect of exterior infusion pressure, influence positive pressure effect.
In addition, existing capsule solid part is unfavorable for liquid communication, due to solid part is identical with capsule portion of material,
