Abstract
The invention discloses a safety indwelling needle which comprises a steel needle, a connecting tube, a vacuum tube and an extension tube. The steel needle is communicated with the extension tube through the connecting tube. The safety indwelling needle is characterized in that an isolation plug is arranged between the steel needle and the extension tube, one end of the extension tube is provided with a heparin cap, the side wall of the heparin cap is provided with an air outlet, steps are arranged on the periphery of the inner side of the air outlet in a surrounding mode, a filter film is welded to the steps, a safety cap is arranged on the outer side of the filter film, and the safety cap is connected to the bottom end of the heparin cap through the connecting tube. According to the safety indwelling needle, the defects of gas propulsion or inverted liquid input caused when medical staff adds medicine into the indwelling needle in the prior art are overcome, the aeroembolism caused by the indwelling needle is avoided, and safety and operability are improved.
Description
Technical field
The present invention relates to technical field of medical treatment mechanical, be specifically related to a kind of safety indwelling needle.
Background technology
Domestic and international companies drops into the research and development of safety blood taking medical device energetically, and safety indwelling needle is in the market very many, and these safety blood taking equipment have a lot of deficiency: first production cost is very high; It two is complex manufacturing; Its three be the quality of production be difficult to ensure; It four is medical personnel's complex operations; Its five be security function be difficult to ensure.At present, conventional disposable remaining needle before use, to need to needle guard on pinhead sleeve to protect syringe needle, such as, prevent syringe needle to be bent or collision etc.During use, when pulling out needle guard, easily cause pricking hazard, but real danger disposal stage after blood sampling completes, after extracting in person of blood collecting's body, when carrying out waste disposal, no matter putting into the process cartridge of specialty or bringing needle guard, the danger of being all easily wounded by stabbing, causes the serious consequences such as medical staff infection.
Summary of the invention
The object of this invention is to provide higher, the sensitiveer safety indwelling needle of a kind of safety to make up the deficiency of above technology.
The technical scheme that the present invention adopts for its technical problem of solution is,
A kind of safety indwelling needle, comprise draw point, connection tube, vacuum tube, extension tube, draw point is communicated with extension tube by connection tube, be provided with batching pig between described draw point and described extension tube, one end of described extension tube is provided with calparine cap, and the sidewall of this calparine cap is provided with air vent, the inside circumference of described air vent is surrounded with step, described step is welded with filter membrane, and described filter membrane arranged outside has safety helmet, and this safety helmet is connected to the bottom of described calparine cap by connection tube.
Further, described step is looped around described air vent inwall, in even convex architecture.
Further, described air vent is made up of transparent material, is convenient to medical worker and observes inside exhaust ports.
The invention has the advantages that, this safety indwelling needle solves when medical worker is to causing gas propulsive during remaining needle dosing or being inverted the shortcoming inputting liquid in the middle of prior art, thus the aeroembolism preventing remaining needle from occurring, improve safety and operability.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of safety indwelling needle that the present invention proposes;
Fig. 2 is the air vent schematic diagram of a kind of safety indwelling needle that the present invention proposes;
Wherein: 1, draw point, 2, connection tube, 3, vacuum tube, 4, extension tube, 5, batching pig, 6, calparine cap, 7, air vent, 8, step, 9, filter membrane, 10, safety helmet.
Detailed description of the invention
The technological means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with diagram and specific embodiment, setting forth the present invention further.
As Fig. 1, shown in Fig. 2, a kind of safety indwelling needle that the present invention proposes, comprise draw point 1, connection tube 2, vacuum tube 3, extension tube 4, draw point 1 is communicated with extension tube 4 by connection tube 2, batching pig 5 is provided with between described draw point 1 and described extension tube 4, one end of described extension tube 4 is provided with calparine cap 6, the sidewall of this calparine cap 6 is provided with air vent 7, the inside circumference of described air vent 7 is surrounded with step 8, described step 8 is welded with filter membrane 9, described filter membrane 9 arranged outside has safety helmet 10, this safety helmet 10 is connected to the bottom of described calparine cap 6 by connection tube 2.
Further, described step 8 is looped around described air vent 7 inwall, in even convex architecture.
Further, described air vent 7 is made up of transparent material, is convenient to medical worker and observes air vent 7 inside.This safety indwelling needle solves when medical worker is to causing gas propulsive during remaining needle dosing or being inverted the shortcoming inputting liquid in the middle of prior art, thus the aeroembolism preventing remaining needle from occurring, improve safety and operability.
More than show and describe ultimate principle of the present invention, principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present invention; the present invention also has various changes and modifications without departing from the spirit and scope of the present invention, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
