Abstract
A kind of safety-type Paracentesis needle holder of remaining needle, including Paracentesis needle holder, the Paracentesis needle holder is fastenedly connected with puncture needle, Paracentesis needle holder is provided with protective cover with puncture needle connection end, the Protection glue that the protective cover includes the telescopic arm of both sides and is fixedly connected with telescopic arm, once retracting action is excessive during the utility model solves current puncture needle use, medical personnel can be accidentally injured by being stained with the puncture needle of blood samples of patients, and then medical personnel can be caused by blood samples of patients the problem of entrained courses of infection, and the utility model is simple and practical, suitable for straight type and Y type remaining needles, with great market popularization value.
Description
Technical field
Medical Devices are the utility model is related to, the safety-type Paracentesis needle holder of especially a kind of remaining needle.
Background technology
Venous detaining needle is a kind of medicine equipment for infusion, and venous detaining needle is easy to operate, is applied to
The puncture at any position, while the pain that patient punctures repeatedly is alleviated, the workload of nursing staff is alleviated, it is clinically deep
Suffered from by shield and welcome.In Clinical practice, puncture needle leads remaining needle sleeve pipe into the vein blood vessel of human body.After seeing blood back, really
Recognize venipuncture success, puncture needle is extracted out, and only the soft remaining needle sleeve pipe of material is retained in vein blood vessel.Decoction leads to
Cross remaining needle sleeve pipe input human body.Remaining needle sleeve pipe is made of the soft material with certain elasticity, can be pacified in human vein
Used in full indwelling time, and the bending synchronous with vein with people's limb motion so that injection site still can be acted freely, will not
The anxiety of spinosity perforating veins.So avoid frequently to puncture to cause suffering to patient.
But found 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 of extraction bottle stopper common in life as an example：When people grips bottle remains stationary on the other hand, another hand is used
When power extracts bottle stopper, the hand for holding bottle stopper has a rapid stopping during the whipping away from bottle is tended to and reversely bounced back
Action, the action is the natural reaction that people bumps against hard thing in order to avoid hand in quick whipping, and basic is difficult to be overcome.
As uncorking the bottle, for medical personnel after firmly puncture needle is extracted, the hand for holding draw point equally has the process of a retraction,
And now syringe needle corresponds to the another hand 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, when processing is useless
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 utility model is in order to solve above-mentioned problem, there is provided the safety-type Paracentesis needle holder of excessively a kind of remaining needle.
What the technical solution of the utility model was realized in：
A kind of remaining needle safety-type Paracentesis needle holder, including Paracentesis needle holder, the Paracentesis needle holder are fastenedly connected with puncture needle,
Paracentesis needle holder is provided with protective cover with puncture needle connection end, and the protective cover includes the telescopic arm of both sides and is fixedly connected with telescopic arm
Protection glue.
The telescopic arm includes some crossbars being end-to-end, and crossbar is overlapping including two middle parts and in overlapping riveting
The expansion link connect.
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 retracting action is excessive during the utility model solves current puncture needle use, wearing for blood samples of patients is stained with
Thorn draw point can accidentally injure medical personnel, and then can cause medical personnel by blood samples of patients the problem of entrained courses of infection, and this
Utility model is simple and practical, suitable for straight type and Y type remaining needles, has great market popularization value.

Embodiment
Embodiment one
As shown in figure 1, the utility model includes Paracentesis needle holder, the Paracentesis needle holder is fastenedly connected with puncture needle, puncture needle
Seat is provided with protective cover, the protection that the protective cover includes the telescopic arm of both sides and is fixedly connected with telescopic arm with puncture needle connection end
Glue, as shown in figure 4, the telescopic arm includes some crossbars being end-to-end, crossbar is overlapping including two middle parts and in weight
The expansion link of folded place's riveting, the protective cover maximum development length are more than needle length 0.1-0.5cm, the Protection glue external diameter
Consistent with the internal diameter of general indwelling needle, the telescopic arm is arranged on the outer both sides of puncture needle.
As shown in Fig. 2 the utility model is after lancet puncture blood vessel, when extracting puncture needle out, because Protection glue is inserted completely
Enter to indwelling needle, and the internal diameter of Protection glue external diameter and indwelling needle is completely the same, as shown in figure 1, incomplete in puncture needle
Extract out in indwelling needle, now, Protection glue is not protected glue outer wall and remaining needle on the contrary by the tractive force of telescopic arm
The frictional force of seat inwall, therefore Protection glue is remained in indwelling needle, telescopic arm stretches with the rear shifting of Paracentesis needle holder,
After being stretched to the limit, as shown in figure 3, Protection glue now is exited indwelling needle by the tractive force of telescopic arm, and because of protective cover
Ultimate tensile elongation, the puncture needle head for making to exit completely in indwelling needle is wrapped in Protection glue, effectively prevents completely
Stab.
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 bag
The lead being fixedly connected with Paracentesis needle holder and the Protection glue being fixedly connected with lead are included, 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, and the lead is arranged on puncture
The both sides of pin, at least two, most preferably three or more than three, the lead.
As shown in fig. 6, the utility model is after lancet puncture blood vessel, when extracting puncture needle out, because Protection glue is inserted completely
Enter to indwelling needle, and the internal diameter of Protection glue external diameter and indwelling needle is completely the same, and remaining needle is not fully drawn out in puncture needle
In seat, now, Protection glue is not had on the contrary by the tractive force of lead is protected rubbing for glue outer wall and indwelling needle inwall
Power, therefore Protection glue is remained in indwelling needle, lead stretches with the rear shifting of Paracentesis needle holder, after being stretched to the limit,
Protection glue now is exited indwelling needle by the tractive force of lead, and because of the ultimate tensile elongation of protective cover, as shown in fig. 7,
The puncture needle head for making to exit completely in indwelling needle is wrapped in Protection glue completely, effectively prevents from stabbing.
