Embodiment Construction

[0039] The invention provides a one-time use aseptic microparticle retention syringe, which is modified according to the existing structure of the syringe, and a filter device is added at the top of the syringe to achieve the purpose of intercepting the microparticles in the liquid medicine during injection and ensuring injection safety.

[0040] Such as figure 1 As shown, the disposable sterile microparticle retention syringe provided by the present invention includes an outer cylinder 3 of an existing common syringe, a liquid pushing rod 4 placed in the outer cylinder, and a needle seat 5 on the front end side of the outer cylinder for holding needles. , The feature of the present invention is that it also includes a filter device 6, which is embedded in the inner wall of the front end of the outer cylinder 3, and is facing the position of the liquid outlet of the needle seat 5.

[0041] This filtering device 6 is made up of a diaphragm 1 and an insert 2, see image 3 shown...

Abstract

The invention discloses a disposable sterile particulate-retaining syringe, which comprises a barrel, a plunger, a needle holder and a filter, the plunger is arranged in the barrel, the needle holder is arranged on one side of the front end of the barrel and is used for holding a needle, the barrel is communicated with the needle holder through a liquid outlet, and the filter is provided with a filter membrane, which is attached on the liquid outlet and can be closed toward the front end and opened toward the rear end. According to the structure design, the thickened interlayer-wrapped round unilaterally hung filter is only arranged in the tip of a conventional and ordinary syringe, the syringe can be automatically opened and closed and suck dissolved medicine during the microflow of the liquid, and can retain particulates in the injection in one step, so that particulates which are 0.45Mu m or bigger cannot be produced in the discharged liquid any more, and thereby the safety of injection is guaranteed.

Description

technical field [0001] The invention belongs to the field of medical equipment, and relates to a syringe, in particular to a disposable aseptic microparticle retention syringe. Background technique [0002] Infusion therapy is an important treatment method, especially intravenous infusion and intravenous injection are widely used because the medicinal liquid directly enters the blood circulation system, and the drug effect is quickly exerted. However, in recent years, the harm caused by foreign matter and particle pollution in injection fluid, especially infusion, has aroused widespread concern, and it is urgent to solve particle pollution. [0003] Intravenous drip and intravenous injection. Particles refer to unintentionally added mobile and insoluble foreign substances and soluble and undissolved drugs in the liquid. Insoluble particles include rubber particles, polyester flakes, flakes, and color spots. , insoluble inorganic salts, activated carbon particles, fibers, an...
