Description

Transfusion device

Technical field

This utility model relates to a kind of medical apparatus and instruments, relates in particular to a kind of transfusion device.

Background technology

At present, a lot of patients can not in time be found when venous transfusion finishes for various reasons, to such an extent as to and cause medicinal liquid in the infusion bottle to be dripped fully occurring blood back to the greatest extent, bring fear for patient and medical personnel.

Summary of the invention

The purpose of this utility model provides a kind of safe and reliable transfusion device.

For achieving the above object, the technical solution adopted in the utility model is:

A kind of transfusion device, include bottle plug puncture unit, bottle plug puncture unit includes pedestal, be fixedly connected with puncture tube above the pedestal, have inlet on the puncture tube, be fixedly connected with the transfusion connection tube below the pedestal, the airtight inlet pipe connection that is connected with of transfusion connection tube one side, the airtight air induction hose that is communicated with of the free end of inlet pipe connection, the airtight air filter that is communicated with of the air induction hose other end, puncture tube, transfusion connection tube, inlet pipe connection and air induction hose is airtight communicates; The free end of transfusion connection tube drips kettle by airtight being communicated with of infusion tube, drip the kettle rear end by the airtight liquid medicine filter that is communicated with of infusion tube, drip on the infusion tube between kettle and the liquid medicine filter and be installed with flow regulator, the liquid medicine filter rear end is by the airtight intravenous needle that is communicated with of infusion tube, it is characterized in that: drip kettle and include the kettle body, be connected with anti-down card thorn on the inwall of kettle body, anti-down card thorn is thorn-like, the thorn point is downward, and anti-down card thorn is structure as a whole with the kettle body; Being provided with the obstruction that suspends in the kettle body, suspending to stop up is inverted cone, and the cone bottom diameter of the obstruction that suspends is greater than the internal diameter that drips kettle rear end infusion tube; The thorn point floor projection of anti-down card thorn is positioned at the flat perspective plane of awl bottom water that suspends and stop up, and has vacuum chamber in the middle of suspension is stopped up, and the conical surface that stops up that suspends concaves.

Because stopping up, the suspension in this utility model is inverted cone, in the venous transfusion process, suspension is blocked under the medicinal liquid buoyancy function and floats on above the medicinal liquid, do not influence normally carrying out of transfusion, when the medicine liquid droplet in dripping kettle is clean, suspension is blocked in and drop to the infusion tube inlet that drips the kettle rear end under the effect of self gravitation, thereby infusion tube is blocked, the medicinal liquid that stoping suspends stops up the rear end continues to import to human body, simultaneously, the setting of anti-down card thorn make suspend be blocked in drip in the kettle can only under can not go up, effectively stoping suspends stops up upwards rollback, the generation of control blood back, so this utility model uses safe and reliable.
