Abstract
The utility model provides a safety remaining needle, includes steel needle, connecting pipe, vacuum tube, extension pipe, the steel needle passes through connecting pipe and extension pipe intercommunication, and its characterized in that, the steel needle with be provided with the batching pig between the extension pipe, the one end of extension pipe is provided with the heparin cap, is provided with the gas vent on the lateral wall of this heparin cap, it has the step to encircle around the inboard of gas vent, the welding has filtration membrane on the step, the filtration membrane outside is provided with the safety helmet, and this safety helmet passes through the connecting pipe and connects the bottom of heparin cap. This safety remaining needle leads to the gaseous shortcoming that impels or invert input liquid as medical staff to keeping somewhere in the middle of having solved prior art when the needle adds the medicine to prevent to keep somewhere the aeroembolism that the needle appears, improve security and maneuverability.
Description
Technical field
This utility model relates to technical field of medical treatment mechanical, is specifically related to a kind of safety indwelling needle.
Background technology
Domestic and international companies puts into the research and development of safety blood taking medical device energetically, and safety indwelling needle in the market is very many, and these safety blood taking equipment have a lot of deficiency: first production cost is significantly high；It two is complex manufacturing；It three is that the quality of production is difficult to ensure that；It four is medical personnel's complex operations；It five is that security function is difficult to ensure that.At present, conventional disposable remaining needle is before use, it is necessary to needle guard on pinhead sleeve to protect syringe needle, for instance 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 put into process cartridge or the upper needle guard of band of specialty, the danger being all easily wounded by stabbing, causes the serious consequences such as medical staff infection.
Utility model content
The purpose of this utility model is to provide higher, the sensitiveer safety indwelling needle of a kind of safety to make up the deficiency of above technology.
This utility model be employed technical scheme comprise that by its technical problem of solution,
A kind of safety indwelling needle, including draw point, connecting tube, vacuum tube, extension tube, draw point is connected with extension tube by connecting tube, being provided with batching pig between described draw point and described extension tube, one end of described extension tube is provided with calparine cap, is provided with air vent on the sidewall of this calparine cap, the inside circumference of described air vent is surrounded with step, being welded with filter membrane on described step, described filter membrane arranged outside has safety helmet, and this safety helmet is connected to the bottom of described calparine cap by connecting tube.
Further, described step is looped around described air vent inwall, in uniform convex architecture.
Further, described air vent is made of clear material, it is simple to medical worker observes inside exhaust ports.
The utility model has the advantage of, this safety indwelling needle solves and causes gas propulsive in the middle of prior art when medical worker is to remaining needle dosing or be inverted the shortcoming of input liquid, thus preventing the aeroembolism that remaining needle occurs, improves safety and operability.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of safety indwelling needle that the utility model proposes；
Fig. 2 is the air vent schematic diagram of a kind of safety indwelling needle that the utility model proposes；
Wherein: 1, draw point, 2, connecting 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
For the technological means making this utility model realize, creation characteristic, reach purpose and effect and be easy to understand, below in conjunction with diagram and specific embodiment, this utility model is expanded on further.
Such as Fig. 1, shown in Fig. 2, a kind of safety indwelling needle that the utility model proposes, including draw point 1, connecting tube 2, vacuum tube 3, extension tube 4, draw point 1 is connected with extension tube 4 by connecting tube 2, it is provided with batching pig 5 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 connecting tube 2.
Further, described step 8 is looped around described air vent 7 inwall, in uniform convex architecture.
Further, described air vent 7 is made of clear material, it is simple to it is internal that medical worker observes air vent 7.This safety indwelling needle solves and causes gas propulsive in the middle of prior art when medical worker is to remaining needle dosing or be inverted the shortcoming of input liquid, thus preventing the aeroembolism that remaining needle occurs, improves safety and operability.
Of the present utility model ultimate principle, principal character and of the present utility model advantage have more than been shown and described.Skilled person will appreciate that of the industry; this utility model is not restricted to the described embodiments; described in above-described embodiment and description is that principle of the present utility model is described; under the premise without departing from this utility model spirit and scope, this utility model also has various changes and modifications, and these changes and improvements both fall within the scope of claimed this utility model.This utility model claims scope and is defined by appending claims and equivalent thereof.
