CN103007387A - Detaining needle port protection cap - Google Patents

Abstract

The invention discloses a detaining needle port protection cap. The detaining needle port protection cap comprises a cylindrical body with one end open, sponge, a capsule, disinfectants and a seal, an internal thread is arranged on the internal surface of the open end and is a standard Luer internal thread, the sponge is positioned in a hollow cavity of the body, a spike is arranged at one closed end of the body, the capsule is positioned between the spike and the sponge, the disinfectants are disposed in the capsule, and the seal is positioned at the open end of the body to enable the open end of the body to be sealed. The capsule is made of gelatin and is punctured easily by the spike under the action of external force, and an anti-slip stripe projection structure is arranged on the outside of the body. The detaining needle port protection cap is disposable, small in size, simple to use and capable of effectively preventing contamination of a detaining needle port, and not only can achieve physical dust prevention and bacteria prevention but also can continuously disinfect an infusion connector through the disinfectants in the sponge.

Description

Remaining needle port protection medicated cap

Technical field

The present invention relates to a kind of remaining needle port protection medicated cap, belong to disposable use medical apparatus and instruments.

Background technology

Venous duct generally uses clinically, yet annual because its joint pollutes the but constantly increase of case that causes iatrogenic disease.Remaining needle for example, claim again the venous cannula pin, can reduce the vascular puncture number of times, alleviate patient's misery, at present in clinical extensive use, but present remaining needle port just arbitrarily is exposed in the air when not using owing to adopt one-way valve structures, enters the probability that vein infects thereby increased from port.

Summary of the invention

The objective of the invention is effectively to prevent patient's infected new type medical equipment remaining needle port protection medicated cap when infusing in order to provide a kind of.It is dustproof both can to have played physics, and the purpose of bacteriological protection can continue disinfective action to infusion connector by the disinfectant solution in the sponge again.

For achieving the above object, the present invention includes main body, sponge, capsule, disinfectant and Sealing piece; Described main body is cylindrical, an end opening, and the inner surface of opening one end is provided with female thread, and female thread is standard Luer interface female thread; Described sponge is positioned at body cavity, and the closed end of main body is provided with a sharp shaped material, and capsule is between sharp shaped material and sponge, and described disinfectant places in the capsule; Sealing piece is positioned at body openings one end, makes body openings one end airtight.Described capsule is that gelatin is made, and is easily punctured by sharp shaped material under external force; Described main body outside is provided with anti-skidding striped bulge-structure.

Adopt said structure, the disposable use of the present invention, structure is small and exquisite, use is simple, can effectively prevent the pollution to the remaining needle port, plays the effect of protecting from infection.

The specific embodiment

The present invention includesmain body 1, sponge 2, capsule 3, disinfectant 4 and Sealing piece 5; Describedmain body 1 is cylindrical, an end opening, and the inner surface of opening one end is provided with female thread 6, and female thread 6 is standard Luer interface female thread; Described sponge 2 is positioned atmain body 1 cavity, and main body 1 a closed end is provided with a sharpshaped material 7, and capsule 3 is between sharpshaped material 7 and sponge 2, and described disinfectant 4 places in the capsule 3; Sealing piece 5 is positioned atmain body 1 opening one end, makesmain body 1 opening one end airtight.Described capsule 3 is made for gelatin, is easily punctured by sharpshaped material 7 under external force.Describedmain body 1 outside is provided with anti-skidding striped bulge-structure 7.Describedmain body 1 is made by medical plastic or medical grade rubber or medical silica-gel or metal.Described disinfectant 3 is 70-75% ethanol, povidone iodine or 70-75% isopropyl alcohol.Described sponge 2 is to be made by medical macromolecular materials.Described medical macromolecular materials are to be made by natural macromolecular material or synthesized polymer material.Described natural macromolecular material refers to Cotton Gossypii, silk, chitin.Described synthesized polymer material refers to polrvinyl chloride, natural rubber, polyethylene, polyamide, polypropylene, polystyrene, silicone rubber, polyester, politef, polymethyl methacrylate or polyurethane.

The Sealing piece 4 of tearing first during use, the female Luer of remaining needle port is screwed in the female thread 5 ofmain body 1 of the present invention, sponge 2 and capsule 3 in extrudingmain body 1 cavity, because capsule 3 is made for gelatin, easily punctured by sharpshaped material 7 under external force, after capsule 3 is punctured, disinfectant 4 in the capsule 3 is released, sponge 2 absorption with high-hydroscopicity energy, when remaining needle port andmain body 1 screwed, sponge 2 discharged the disinfectant 4 of its absorption, and the remaining needle port is immersed in the disinfectant 3, port is continued sterilization, and it is dustproof to play physics, the effect of bacteriological protection.
