SUMMERY OF THE UTILITY MODEL
The utility model discloses an among the solution above-mentioned background art, current syringe does not have filter equipment, the insoluble particle in the liquid medicine can't be filtered, there is insoluble particle to get into the human body and can not be metabolized at the injection in-process, can block up heart brain or pulmonary blood vessel or form the parcel at the part of blocking and be called granuloma, it is healthy or cause life danger to influence, the technology is complicated simultaneously, the cost is high, difficult realization, it is inconvenient to use, waste sanitary resource scheduling problem, filter equipment is laid in syringe needle department to this patent, good manufacturing, the cost is low, high durability and convenient use, need not change the syringe structure yet, and provide a syringe needle that has filtering capability.
A syringe needle with a filtering function comprises a needle body, a first filter screen, a second filter screen, a first round ball and a second round ball, wherein the first filter screen is arranged in the needle body;
a first channel and a second channel are arranged in the needle head main body;
a first inverted conical hole is formed in the first channel;
a second inverted conical hole is formed in the second channel;
the first inverted conical hole and the second inverted conical hole are opposite in direction;
the first filter screen is arranged in the front of the first inverted conical hole;
the second filter screen is arranged at the front part of the second inverted conical hole;
the first round ball is arranged between the first filter screen and the first inverted conical hole;
the second round ball is arranged between the second filter screen and the second inverted conical hole;
the utility model discloses a theory of operation and process:
when the liquid medicine is extracted, the liquid medicine enters the first channel and the second channel respectively, when the liquid medicine passes through the first channel, the first round ball moves backwards, the first inverted conical hole is opened, the first channel is smooth, when the liquid medicine passes through the second channel, the second round ball moves backwards, the second inverted conical hole is blocked by the second round ball, the second channel is closed, the liquid medicine passes through the first channel, the first inverted conical hole and the first filter screen enter the injector, when the liquid medicine passes through the first filter screen, the first filter screen filters the liquid medicine once, and particles are left on the surface of the first filter screen.
When the liquid medicine is injected, the liquid medicine enters the first channel and the second channel respectively, when the liquid medicine passes through the first channel, the first round ball moves forwards, the first inverted conical hole is blocked by the first round ball, the first channel is closed, when the liquid medicine passes through the second channel, the second round ball moves forwards, the second inverted conical hole is opened, the second channel is unblocked, the liquid medicine passes through the second channel, the second inverted conical hole and the second filter screen enter a human body, when the liquid medicine passes through the second filter screen, the second filter screen performs secondary filtration on the liquid medicine, and particles are left on the surface of the second filter screen.
The utility model has the advantages that:
the utility model discloses simple structure, convenient operation carries out twice filtration to the liquid medicine, and the filter screen can effectively filter the particle in the liquid medicine, improves medical personnel work efficiency, can avoid the interior granule of injection liquid to get into the human body, guarantees to use medicine safety, prevents that the granule from blockking up heart brain or pulmonary blood vessel, improves the security to the human body.
