Description
Technical field
The present invention relates to medical device technical field of infusing, be specifically related to a kind of safety indwelling needle.
Background technology
Safety indwelling needle is widely applied in clinic at present, and it uses the form of flexible catheter set draw point, flexible catheter and steel
Pin puncture simultaneously human vas success after, extract out draw point and flexible catheter is retained in human vas, it can subtract in blood vessel indwelling a couple of days
Misery that few patient causes because of venipuncture repeatedly and to the fear having an injection, alleviates the impatience of patient, it is simple to clinical
Medication and critical, the infusion rescuing medication of critical patient, alleviate the workload of nurse.
Common safety indwelling needle is after clinic punctures, and the draw point of extraction is not because processing in time, or discarded
During, it is impossible to effectively protecting draw point so that in this process, exposed needle point is easily to patient or associated care
Personnel are formed and stab/scratch, and cause cross infection.Arbitrarily put simultaneously, easily cause environmental pollution.Therefore at secured location
After the success of pin puncture vessel, carry out draw point reclaiming protection be clinical in the urgent need to.
Therefore, for the problems referred to above, the present invention proposes a kind of new technical scheme.
Summary of the invention
It is an object of the invention to provide a kind of rational in infrastructure, operational approach, can reclaim draw point effectively, it is to avoid
The safety indwelling needle of potential safety hazard.
The present invention is achieved through the following technical solutions:
A kind of safety indwelling needle, including conduit, catheter block, draw point, recovery cylinder and slide assemblies, is provided with riveting in described catheter block
Nail, described rivet interlacement conduit, it is installed with batching pig in described catheter block, described draw point is through batching pig and stretches to lead
In pipe, matching with slide assemblies in the other one end of described draw point, described slide assemblies is positioned at recovery cylinder, and described slide assemblies includes
Slide rail and slide block, described draw point one end is connected with slide block, and described slide block is installed on the slide rail upper end of draw point both sides, described recovery
Drum outer wall sets and offers chute, and described chute is provided with manual block, and described manual block is connected with slide block, described recovery cylinder with lead
Base is structure as a whole.
Further, described catheter block one end connects positive pressure connector by extension tube, and described positive pressure connector is just provided with
Pressure valve.
Further, described extension tube is provided with and only stays valve.
Further, described rivet is plastic rivet.
Further, described catheter block is provided with and holds needle handle.
Further, it is provided with protective pipe sleeve outside described conduit.
The invention has the beneficial effects as follows: present configuration is simple, easy to operate, by the recovery cylinder of catheter block rear end, with
And draw point can be reclaimed by slide assemblies in recovery cylinder effectively, after preventing draw point from directly extracting out, if can not return in time
Receive, the potential safety hazard such as the cross-contamination caused, play the effect of protection, improve its practicality.

Detailed description of the invention
Illustrate below in conjunction with the accompanying drawings invention is described further.
As shown in Figure 1 and 2, a kind of safety indwelling needle, including conduit 3, catheter block 1, draw point 5, recovery cylinder 6 and slide assemblies,
Being provided with rivet 2 in catheter block 1, rivet 2 connects conduit 3, is installed with batching pig 4 in catheter block 1, and draw point 5 is through batching pig 4
And stretching in conduit 3, matching with slide assemblies in the other one end of draw point 5, slide assemblies is positioned at recovery cylinder 6, slide assemblies bag
Including slide rail 7 and slide block 8, draw point 5 one end is connected with slide block 8, and slide block 8 is installed on slide rail 7 upper end of draw point 5 both sides, recovery cylinder 6
Outer wall sets and offers chute 9, and chute 9 is provided with manual block 10, and manual block 10 is connected with slide block 8, recovery cylinder 6 and catheter block 1
It is structure as a whole.
In the present embodiment, catheter block 1 one end connects positive pressure connector 11 by extension tube 12, and positive pressure connector 11 is provided with
Positive valve 13.
In the present embodiment, extension tube 12 is provided with and only stays valve 14.
In the present embodiment, rivet 3 is plastic rivet.
In the present embodiment, catheter block 1 is provided with and holds needle handle 15.
