Abstract
The utility model discloses a kind of anti-particle pass filters of syringe, including syringe needle and syringe, it is characterised in that: syringe needle is connected with syringe by filtering converter, and syringe needle back-end sealing is arranged on syringe needle connector, and filtration converter is arranged in upper end；When taking out medicine, without using filtration converter, syringe needle directly connect use with syringe, drug is extracted and is prepared, after the completion of extraction when injecting human body, syringe needle is removed, syringe needle, syringe are connected with filtration converter, then injection drug is carried out to patient, particle, impurity are directly blocked in empty cylinder by strainer, guarantee that drug enters in human body safely without particle.The utility model structure is simple and convenient to operate, securely and reliably, and low cost is easily promoted, and be can avoid injecting fluid endoparticle and is entered human body, guarantees drug safety, is prevented particle blocking heart and brain or pulmonary vascular, is improved the safety to human body.
Description
Technical field
The utility model relates to a kind of medical instrument, in particular to a kind of anti-particle pass filter of syringe.
Background technique
Syringe be by syringe needle (by needle point, needle stalk, pintle constitutes) and syringe (by nipple, sky cylinder, piston, piston shaft and
Piston handle constitute) constitute, mainly with inject or take out vehicle, especially be used for intramuscular, subcutaneous, intradermal, acupuncture point, intravenous injection
With venous transfusion dosing with make up a prescription；The syringe of clinical application at present is especially repeated multiple times when syringe needle penetrates into bottle cap to be pierced into such as
Preparing hypersensitive test medical fluid or preparing the medical fluids such as venous transfusion is that may generating insoluble micro-particle, it enters as a kind of foreign matter
Human body cannot be metabolized, and can block heart and brain or pulmonary vascular, unhealthful or cause life danger, or cause human body long-term
, potential, irreversible damage, particle pollution is one of the major issue of current clinical application, in syringe needle or syringe cream
Filter device is added at head, manufacture is difficult, cost height increases Medical Expense for Patients and waste health resources.
Summary of the invention
The purpose of this utility model is to solve above-mentioned existing syringe itself there are insoluble micro-particles during injection
Into human body, it cannot be metabolized in human body, can block heart and brain or pulmonary vascular, unhealthful or cause life danger, existing
The problems such as pintle portion adds the high-leveled and difficult realization of filter device its cost, and provide a kind of anti-particle pass filter of syringe.
A kind of anti-particle pass filter of syringe, including syringe needle and syringe, it is characterised in that: syringe needle and syringe are turned by filtration
Parallel operation is connected, and has the first external screw thread on the nipple of syringe front end, filtration converter includes conversion head and strainer, inside conversion head
For through-hole, rear end has the first internal screw thread, and front end has syringe needle connector, has the second external screw thread, strainer on syringe needle connector
It is arranged in conversion head, syringe needle back-end sealing is arranged on syringe needle connector, on the first internal screw thread and nipple of conversion head rear end
The first external screw thread match, filtration converter setting has the second internal screw thread in upper end in the rear end pintle of syringe needle, the
Two internal screw threads are matched with Supramammillary first external screw thread, and the second internal screw thread is matched with the second external screw thread.
The working principle and process of the utility model:
When taking out medicine, without using filtration converter, syringe needle directly connect use with syringe, is extracted and matched to drug
System, after the completion of extraction before injecting human body, syringe needle is removed, the second internal screw thread is matched with the second external screw thread, the first internal screw thread
It is matched with Supramammillary first external screw thread, syringe needle, syringe is connected with filtration converter connector, then patient is infused
Drug is penetrated, particle, impurity are directly blocked in empty cylinder by strainer, guarantee that drug enters in human body safely without particle.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the structural decomposition diagram of the utility model.
Fig. 3 is the structural schematic diagram of the utility model filtering crossover sub.
Specific embodiment
It please refers to shown in Fig. 1, Fig. 2 and Fig. 3, a kind of anti-particle pass filter of syringe, including syringe needle 1 and syringe 2, feature
Be: syringe needle 1 is connected with syringe 2 by filtering converter 3, has the first external screw thread 211, filter on 2 front end nipple 21 of syringe

Back-end sealing is arranged on syringe needle connector 312, the first internal screw thread 311 and the first outer spiral shell on nipple 21 of 31 rear end of conversion head
Line 211 matches, and filtration converter 3, which is arranged in 2 upper end of syringe, the rear end pintle of syringe needle 1, has the second internal screw thread 11, and second
Internal screw thread 11 is matched with the first external screw thread 211 on nipple 21, and the second internal screw thread 11 is matched with the second external screw thread 313.
The working principle and process of the utility model:
It please refers to shown in Fig. 1, Fig. 2 and Fig. 3, when taking out medicine, without using filtration converter 3, the second internal screw thread 11 and cream
The first external screw thread 211 on first 21 matches, and syringe needle 1 directly connect use with syringe 2, is extracted and is prepared to drug, takes out
In injection human body Xiao after the completion of taking, syringe needle 1 is removed, the second internal screw thread 11 is matched with the second external screw thread 313, the first internal screw thread
311 match with the first external screw thread 211 on nipple 21, syringe needle 1, syringe 2 are connected with filtration converter 3, then to disease
People carries out injection drug, and particle, impurity are directly blocked in empty cylinder by strainer 32, guarantees that drug enters in human body safely without micro-
Grain.
