Abstract

The utility model relates to a medical device, in particular to an intravenous syringe used for intravenous injection. The intravenous syringe comprises a syringe cylinder, a syringe needle and a propulsion stopper, wherein the syringe needle is connected with the front end of the syringe cylinder and communicated with an inner cavity of the syringe cylinder; the propulsion stopper is positioned in the syringe cylinder; the intravenous syringe is characterized in that a filter syringe needle is inserted on the syringe needle; a filter sheet is arranged in an inner cavity of the filter syringe needle, which is communicated with the syringe needle; and by adopting the intravenous syringe, contaminants harmful to the human body can be filtered, such as rubber particulates, fiber and bacteria in liquid medicine, and harm to a patient can be reduced to the greatest extent; moreover, the intravenous syringe is simple, convenient, practical and effective.

Description

Intravenous injector

Technical field

This utility model relates to a kind of medical apparatus and instruments, especially a kind ofly is used for intravenous intravenous injector.

Background technology

The intravenous injection medicinal liquid is one of important means in the treatment, clinically in the layoutprocedure of Chang Yong some intravenous injection medicinal liquids, all to pass the medicine bottle cap rubber stopper repeatedly for several times, like this, with regard to the rubber particle that will have inevitably, fiber and germ contamination medicinal liquid, existing most disposable intravenous injector is that syringe needle is directly advanced by in injector's body, there is not defecator, like this, a large amount of rubber particles, fiber and antibacterial are both with the medicinal liquid intravasation, because the diameter of this microgranule is greater than the diameter of blood capillary, thereby can bring various disease of capillaries for the patient.

Summary of the invention

The purpose of this utility model provides a kind ofly can carry out filtering intravenous injector to medicinal liquid, the rubber particle in the medicinal liquid, fiber and antibacterial can be filtered out.

This utility model is that the technical scheme that the technical solution problem is adopted is:

Intravenous injector, comprise syringe, be connected the syringe needle of syringe front end and syringe intracavity inter-connection and be positioned at the promotion plug of syringe, it is characterized in that: plug-in mounting filtering needle on the described syringe needle, be provided with filter, the draw point of the other end plug-in mounting hollow of filtering needle in described filtering needle and the inner chamber that syringe needle is connected.

Owing to adopted said structure, but harmful pollutant such as the rubber particle in this utility model filtering liquid medicine, fiber and antibacterial reduce the injury to the patient to greatest extent, and this utility model is simple, convenient, effective.

Description of drawings

Fig. 1 is the structural representation of an embodiment of this utility model.

Fig. 2 is the enlarged diagram of this utility model defecator.

The specific embodiment

As shown in the figure, intravenous injector described in the utility model, comprise syringe 1, be connected the syringe needle 2 of syringe 1 front end and syringe 1 intracavity inter-connection and be positioned at the promotion plug 3 of syringe 1, plug-in mounting filtering needle 4 on the described syringe needle 2, filtering needle 4 is similar with syringe needle 2 shapes, the needle guard end of filtering needle 4 is sleeved on the entry needle of syringe needle 2, be provided with filter 5 in described filtering needle 4 and the inner chamber that syringe needle 2 is connected, and the internal chamber wall of the filtering needle 4 at the size of filter 5 and place, filter 5 places is complementary the draw point 6 of the other end plug-in mounting hollow of filtering needle 4.Filter 5 is divided into two chambeies with the inner chamber of filtering needle 4, medicinal liquid is because the extruding of promotion plug 3 flows into filtering needle 4 by syringe needle 2, after filter 5 filtrations, squeeze in patient's body by the entry needle of filtering needle 4, after medicinal liquid filters through filter 5, can significantly reduce morbific pollutant such as rubber particle, fiber and antibacterial wherein, reduce infringement to greatest extent the patient.

Claims

1. intravenous injector, comprise syringe (1), be connected syringe (1) front end and syringe (1) intracavity inter-connection syringe needle (2), be positioned at the promotion plug (3) of syringe (1), it is characterized in that: described syringe needle (2) is gone up plug-in mounting filtering needle (4), be provided with filter (5), the draw point (6) of the other end plug-in mounting hollow of filtering needle (4) in described filtering needle (4) and the inner chamber that syringe needle (2) is connected.
