Abstract
The invention discloses a kind of anti-particulate pass filter 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 on its upper end；When taking out medicine, without using filtration converter, syringe needle is directly connected use with syringe, medicine is extracted and prepared, after the completion of extraction when injecting human body, syringe needle is removed, syringe needle, syringe are connected with filtration converter, then injection medicine is carried out to patient, particulate, impurity are directly blocked in empty cylinder by filter screen, ensure that medicine enters in human body safely without particulate.The present invention is simple in construction, easy to operate, safe and reliable, and low cost is easily promoted, and injecting fluid endoparticle can be avoided to enter human body, ensures drug safety, prevents particle from blocking heart and brain or pulmonary vascular, improves the security to human body.
Description
Technical field
The present invention relates to a kind of medical instrument, more particularly to a kind of anti-particulate pass filter of syringe.
Background technology
Syringe be by syringe needle (by needle point, pin stalk, pintle forms) and syringe (by nipple, empty cylinder, piston, piston shaft and
Piston handle is formed) form, mainly with injecting or taking out vehicle, particularly for intramuscular, subcutaneous, intracutaneous, acupuncture point, intravenous injection
With venous transfusion dosing with making up a prescription；The syringe of clinical practice at present is particularly repeated multiple times piercing when syringe needle penetrates into bottle cap such as
It is that may producing insoluble micro-particle, it enters as a kind of foreign matter to prepare hypersensitive test decoction or prepare the decoctions such as venous transfusion
Human body can not be metabolized, and can block heart and brain or pulmonary vascular, unhealthful or cause life danger, or cause human body long-term
, potential, irreversible infringement, particulate pollution is one of major issue of current clinical application, in syringe needle or syringe breast
Filter is added at head, manufacture is difficult, cost is high increases Medical Expense for Patients and waste health resources.
The content of the invention
The invention aims to solve above-mentioned existing syringe to have insoluble micro-particle entrance during injection in itself
It can not be metabolized human body in human body, can block heart and brain or pulmonary vascular, unhealthful or cause life danger, be existing in pin
Spigot adds its cost of filter high-leveled and difficult the problems such as realizing, and provides a kind of syringe anti-particulate pass filter.
A kind of anti-particulate pass filter of syringe, including syringe needle and syringe, it is characterised in that：Syringe needle is turned with syringe by filtration
Parallel operation is connected, and has the first external screw thread on the nipple of syringe front end, and filtration converter includes conversion head and filter screen, inside conversion head
For through hole, rear end has the first internal thread, and front end has syringe needle connector, has the second external screw thread, filter screen 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 thread and nipple of conversion head rear end
The first external screw thread be engaged, filtration converter is arranged on its upper end, has the second internal thread in the rear end pintle of syringe needle, the
Two internal threads are engaged with Supramammillary first external screw thread, and the second internal thread is engaged with the second external screw thread.
The operation principle and process of the present invention：
When taking out medicine, without using filtration converter, syringe needle is directly connected use with syringe, medicine is extracted and matched somebody with somebody
System, after the completion of extraction before human body is injected, syringe needle is removed, the second internal thread is engaged with the second external screw thread, the first internal thread
It is engaged with Supramammillary first external screw thread, syringe needle, syringe is connected with filtration converter joint, then patient noted
Medicine is penetrated, particulate, impurity are directly blocked in empty cylinder by filter screen, ensure that medicine enters in human body safely without particulate.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Fig. 2 is the structural decomposition diagram of the present invention.
Fig. 3 is the structural representation of present invention filtering crossover sub.

Back-end sealing is arranged on syringe needle connector 312, the first internal thread 311 and the first outer spiral shell on nipple 21 of the rear end of conversion head 31
Line 211 is engaged, and filtration converter 3 is arranged on the upper end of syringe 2, has the second internal thread 11 in the rear end pintle of syringe needle 1, and second
Internal thread 11 is engaged with the first external screw thread 211 on nipple 21, and the second internal thread 11 is engaged with the second external screw thread 313.
The operation principle and process of the present invention：
Refer to shown in Fig. 1, Fig. 2 and Fig. 3, when taking out medicine, without using filtration converter 3, the second internal thread 11 and breast
The first external screw thread 211 on first 21 is engaged, and syringe needle 1 is directly connected use with syringe 2, and medicine is extracted and prepared, and takes out
In injection human body Xiao after the completion of taking, syringe needle 1 is removed, the second internal thread 11 is engaged with the second external screw thread 313, the first internal thread
311 are engaged 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 medicine, and particulate, impurity are directly blocked in empty cylinder by filter screen 32, ensures that medicine enters in human body safely without micro-
Grain.
