Description
Technical field
The present invention relates to venous detaining needle technical fields, more particularly to a kind of anti-venous indwelling needle.
Background technique
In recent years, venous detaining needle application range constantly expands, and is widely used in clinical Zhong Ge department.Vein stays
Set needle use can be reduced patient due to venipuncture repeatedly caused by pain and to the fear having an injection, mitigate the impatience of family members
Mood is convenient for clinical application, mitigates the workload of nurse, reduces patient pain.The withdraw of the needle after use of existing venous detaining needle,
Syringe needle is polluted by the blood of patient, and medical staff is easy to be stabbed and held by syringe needle when pulling away or clearing up discarding remaining needle
Easy infection disease, while discarded syringe needle is exposed be easy to cause environmental pollution in the environment, there are serious security risks.Research
Prove that nurse is the high-risk professional colony of blood born diseases, nurse avoids needle from stabbing infection in venipuncture in order to prevent
Risk has had anti-venous indwelling needle to wrap needle point with special device using telescopic design at present, or with stainless
The mode that the modes such as steel bomb piece, card, intermediate plate wrap needle point stabs risk to reduce needle, directly utilizes there are also a kind of structure
Intermediate irregularity body axis decentraction stops needle point to pass through, but existing technology can not fully meet zero wind stabbed
Danger.
Therefore, to solve the above problems, the present invention provides a kind of new technical solutions.
Summary of the invention
The object of the present invention is to provide a kind of anti-venous indwelling needles.
Used technical solution is the present invention in view of the above technical defects:
A kind of anti-venous indwelling needle, including puncture needle, threeway catheter block, casing and needle stand, the puncture needle is movably
The front end of threeway catheter block is plugged, the rear end detachable connection casing of the threeway catheter block, described sleeve pipe is with respect to three admittances
The other end of tube socket connects needle stand, and described sleeve pipe is set as a section fishing rod shape, a section card of fishing rod shape casing front end
In threeway catheter block, one section of rearmost end of fishing rod shape casing is stuck in needle stand.
Further, several sections in centre of the fishing rod shape casing block mutually, are fixed connection.
Further, being internally provided with for a section of the front end of the fishing rod shape casing just reaches the seam that puncture needle passes through
Gap.
Further, the length that the length of a section of the front end of the fishing rod shape casing is greater than gap protects needle point not outer
Dew.
Further, the fishing rod shape casing is retractable structure, and casing shrink is in needle stand when leaving unused, casing when use
Fishing rod construction open stretching, extension section by section.
Further, the threeway catheter block is transparent material.
The beneficial effects of the present invention are: general structure of the invention is set as fishing rod shape, pass through beating section by section for fishing rod casing
Stretching, extension is opened, all after stretching, extension, in one section of front end of the needle point retraction fishing rod casing with blood, and by the way that gap is arranged,
It after puncture needle pinch in, can not be just pierced by gap, protect needle point not exposed, realize anti-acupuncture effect.
Detailed description of the invention
Present invention is further described in detail with reference to the accompanying drawings and detailed description.
Fig. 1 is the structural diagram of the present invention.
Wherein: 1, puncture needle, 2, threeway catheter block, 3, casing, 4, needle stand.
Specific embodiment
In order to deepen the understanding of the present invention, below in conjunction with embodiment and attached drawing, the invention will be further described, should
The examples are only for explaining the invention, does not restrict the protection scope of the present invention.
A kind of anti-venous indwelling needle as shown in Figure 1, including puncture needle 1, threeway catheter block 2, casing 3 and needle stand 4,
Puncture needle 1 movably plugs the front end of threeway catheter block 2, the rear end detachable connection casing 3 of threeway catheter block 2, casing 3
The other end of opposite threeway catheter block 2 connects needle stand 4, and casing 3 is set as a section fishing rod shape, fishing rod shape casing 3 most before
One section at end is stuck in threeway catheter block 2, and one section of rearmost end of fishing rod shape casing 3 is stuck in needle stand 4.
In the present embodiment, several sections in the centre of fishing rod shape casing 3 block mutually, are fixed connection.
In the present embodiment, being internally provided with for a section of the front end of fishing rod shape casing 3 just reaches what puncture needle passed through
Gap, gap is comparatively fine, and depth is preferably 5mm, and the length of a section of 3 front end of fishing rod shape casing is considerably beyond 5mm, fish
The length that the length of one section of the front end of pole shape casing 3 is greater than gap protects needle point not exposed,.
In the present embodiment, fishing rod shape casing 3 is retractable structure, and casing 3 is contracted in needle stand 4 when idle, when use
The fishing rod construction of casing 3 opens stretching, extension section by section.
In the present embodiment, threeway catheter block is transparent material.
In actual use, puncture needle 1 punctures human body, starts to pull out needle after puncturing successfully, is stuck in that on threeway catheter block 2
One section is fixed, from it after fishing rod casing 3 open stretching, extension section by section, until all stretching, extension finishes, the retraction of needle point with blood
In one section of front end of fishing rod casing 3, slightly firmly that section of front end is extracted from threeway catheter block 2, puncture needle passes through
It just can not be again pierced by tiny gap in gap retraction casing 3, protect needle point not exposed, realize anti-pricker principle.
The beneficial effects of the present invention are: general structure of the invention is set as fishing rod shape, pass through beating section by section for fishing rod casing
Stretching, extension is opened, all after stretching, extension, in one section of front end of the needle point retraction fishing rod casing with blood, and by the way that gap is arranged,
It after puncture needle pinch in, can not be just pierced by gap, protect needle point not exposed, realize anti-acupuncture effect.
These are only the preferred embodiment of the present invention, is not intended to restrict the invention, for those skilled in the art
For member, the invention may be variously modified and varied.All within the spirits and principles of the present invention, it is made it is any modification,
Equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
