Description
Technical field
The present invention relates to armarium, especially a kind of remaining needle safety Paracentesis needle holder.
Background technology
Venous detaining needle is a kind of medical apparatus and instruments for infusion, and venous detaining needle is easy to operate, it is adaptable to
The puncture at any position, while alleviating the pain of patient's repeated localised puncture, alleviates the workload of nursing staff, clinically deep
Suffered from by shield and being welcome.In Clinical practice, puncture needle leads remaining needle sleeve pipe to enter the vein blood vessel of human body.After seeing blood back, really
Recognize venipuncture success, puncture needle is extracted out, and only the remaining needle sleeve pipe of made of soft is retained in vein blood vessel.Medicinal liquid leads to
Cross remaining needle sleeve pipe input human body.Remaining needle sleeve pipe is made using the soft material with certain elasticity, can pacify in human vein
Use in full indwelling time, and synchronous with vein with people's limb motion bend so that injection site still can free action, will not
The anxiety of spinosity perforating veins.So avoid frequently to puncture to cause suffering to patient.
But find in clinical manipulation, when medical personnel extract the puncture needle of venous detaining needle out, the needle point of puncture needle
Have and certainly possible stab medical personnel.The reason for causing this accident is commonly seen but generally by people's ignorance mainly due to a kind of
Natural reaction, by taking the action for extracting bottle stopper common in life as an example：When people grips on the other hand bottle remains stationary, another handss are used
When power extracts bottle stopper, the handss for holding bottle stopper have a rapid stopping during the whipping away from bottle is tended to and reversely bounce back
Action, the action is the natural reaction that people bumps against hard thing in order to avoid handss in quick whipping, basic to be difficult to be overcome.
As uncorking the bottle, after firmly puncture needle is extracted, the handss for holding draw point equally have the process of a retraction to medical personnel,
And now syringe needle corresponds to the another handss of medical personnel just.Once retracting action is excessive, the puncture needle of blood samples of patients is stained with
Medical personnel can be accidentally injured, and then medical personnel can be caused by entrained courses of infection in blood samples of patients.In addition, it is useless when processing
It is equally possible when abandoning puncture needle to cause staff to be wounded by stabbing, difficulty is caused to medical waste special treatment, it is serious so as to cause
Social safety hidden danger.
The content of the invention
The present invention is in order to solve above-mentioned problem, there is provided excessively a kind of remaining needle safety Paracentesis needle holder.
The technical scheme is that what is be achieved in that：
A kind of remaining needle safety Paracentesis needle holder, including Paracentesis needle holder, the Paracentesis needle holder is fastenedly connected with puncture needle, punctures
Needle stand and puncture needle connection end are provided with protective cover, telescopic arm that the protective cover includes both sides and the guarantor being fixedly connected with telescopic arm
Shield glue.
The telescopic arm includes some crossbars being end-to-end, and crossbar includes that two middle parts overlap and in overlapping riveting
The expansion link for connecing.
The protective cover maximum development length is more than needle length 0.1-0.5cm.
The Protection glue external diameter is consistent with the internal diameter of general indwelling needle.
The telescopic arm is arranged on the outer both sides of puncture needle.
Once the present invention is solved during current puncture needle use, and retracting action is excessive, the puncture steel of blood samples of patients is stained with
Pin can accidentally injure medical personnel, and then can cause medical personnel by the problem of entrained courses of infection in blood samples of patients, and the present invention
It is simple and practical, it is adaptable to straight type and Y type remaining needles, with great market popularization value.

Specific embodiment
Embodiment one
As shown in figure 1, the present invention includes Paracentesis needle holder, the Paracentesis needle holder is fastenedly connected with puncture needle, Paracentesis needle holder and puncture
Pin connection end is provided with protective cover, telescopic arm that the protective cover includes both sides and the Protection glue being fixedly connected with telescopic arm, such as Fig. 4
Shown, the telescopic arm includes some crossbars being end-to-end, and crossbar includes that two middle parts overlap and in overlapping riveting
Expansion link, protective cover maximum development length is more than needle length 0.1-0.5cm, and the Protection glue external diameter is stayed with general
The internal diameter for putting needle stand is consistent, and the telescopic arm is arranged on the outer both sides of puncture needle.
As shown in Fig. 2 the present invention is after lancet puncture blood vessel, when extracting puncture needle out, due to Protection glue it is fully-inserted extremely
In indwelling needle, and Protection glue external diameter is completely the same with the internal diameter of indwelling needle, as shown in figure 1, not being fully drawn out in puncture needle
In indwelling needle, now, Protection glue is not protected on the contrary in glue outer wall and indwelling needle by the pull strength of telescopic arm
The frictional force of wall, therefore Protection glue remained in indwelling needle, telescopic arm is stretched with the rear shifting of Paracentesis needle holder, stretching
To the limit, as shown in figure 3, Protection glue now is subject to the pull strength of telescopic arm to exit indwelling needle, and because of the pole of protective cover
Limit tensile elongation, makes the puncture needle head exited completely in indwelling needle be wrapped in completely in Protection glue, effectively prevents from stabbing.
Embodiment 2
The present embodiment is roughly the same with the architectural feature of embodiment 1, as shown in figure 5, its difference is：The protective cover include with
Lead that Paracentesis needle holder is fixedly connected and the Protection glue being fixedly connected with lead, the protective cover maximum development length is more than puncturing
Pin length 0.1-0.5cm, the Protection glue external diameter is consistent with the internal diameter of general indwelling needle, and the lead is arranged on puncture needle
Both sides, at least two, most preferably three or more than three, the lead.
As shown in fig. 6, the present invention is after lancet puncture blood vessel, when extracting puncture needle out, due to Protection glue it is fully-inserted extremely
In indwelling needle, and Protection glue external diameter is completely the same with the internal diameter of indwelling needle, is not fully drawn out in indwelling needle in puncture needle,
Now, Protection glue is not had on the contrary the frictional force for being protected glue outer wall and indwelling needle inwall by the pull strength of lead, because
This Protection glue is remained in indwelling needle, and lead is stretched with the rear shifting of Paracentesis needle holder, after being stretched to the limit, now
Protection glue is subject to the pull strength of lead to exit indwelling needle, and because of the ultimate tensile elongation of protective cover, as shown in fig. 7, making completely
The puncture needle head exited in indwelling needle is wrapped in completely in Protection glue, effectively prevents from stabbing.
