Abstract
The utility model relates to the technical field of medical instrument, that is a dropper of infusion device with automatic protection function, which comprises a dropper body and a dropper cap covering on the dropper body, a liquid inlet on the dropper cap, a feeding opening and a feeding opening cap covering on the feeding opening, a gasvent and an air filter mounted inside the gasvent as well as a liquid outlet, wherein, the inner chamber of the dropper body has a hollow spherical sealing ball, and the surface of the liquid outlet on the inner chamber of the dropper body is a smooth arc surface which can be pressed close to the outline of the sealing ball. The dropper is characterized in that when the liquid is nearly to run out during the intravenous injection, the sealing ball will block the liquid outlet of the dropper of infusion device automatically to avoid injecting the air into the blood of the patient to endanger the patient, receiving the effect of safeguarding the patient automatically.
Description
Technical field:
This utility model relates to technical field of medical instruments, refers in particular to a kind of transfusion device burette with automatic protection functions.
Background technology:
In existing transfusion device, mostly on tube for transfusion, connect a burette, be used to adjust the rate of titration of transfusion, add usefulness such as medicinal liquid, but the patient is in infusion process, since nurse job is busy or the careless liquid of not finding of nursing staff near being totally lost, at this moment, close tube for transfusion or extract infusion needle as if untimely, air will be imported in the blood samples of patients, air in the input blood samples of patients is too much, will bring life danger to the patient, 02216958.X number Chinese patent discloses a kind of structure improved transfusion device burette, problem is when approaching being totally lost of liquid that the patient infuses, if burette has certain inclination, then gasket seal is not necessarily just just sealed liquid outlet, and loses sealing function.
The utility model content:
The purpose of this utility model provide a kind of patient in transfusion when being totally lost, the device of the liquid outlet on the close transfusion device burette automatically causes danger to avoid air imported in the blood samples of patients.
This utility model is achieved in that the transfusion device burette of band automatic protection functions; by body and lid Guan Gai, inlet that pipe covers, filling opening and lid thereon thereon liquid feeding flap, blow vent and be installed in its inner air filter and liquid outlet is formed, wherein: the inner chamber at body has the hollow ball shape ball sealer of an external diameter greater than the liquid outlet diameter.
The surface of the liquid outlet of above-mentioned tube cavity is the curved surfaces of the slyness that can fit with the profile of hollow ball shape ball sealer.
The outstanding compared to existing technology advantage of this utility model is: when the liquid of patient's transfusion when being totally lost; ball sealer is with the liquid outlet of automatic closed infusion set burette; thereby avoid air imported in the blood samples of patients and, played automatic protection patient's effect to the danger that the patient brings.
