Technical field
The utility model belongs to technical field of medical instrument, and in particular to a kind of remaining needle.
Background technology
With the continuous development of China's medical industry, market increasingly increases for the demand of various types of remaining needles.Stay
Put pin and be also known as venous catheter needle, its use can reduce patient because venipuncture repeatedly and caused by pain and the fear to having an injection
Sense, mitigate the impatience of family numbers of patients, be easy to clinical application, anxious, the rescue medication of critical patient, mitigate the work of nurse
Amount, patient pain is reduced, thus venous detaining needle is in wide clinical application.
Remaining needle, its main building block include to be retained in endovascular soft conduit, and stainless steel is worn
Thorn guiding needle tubing.Conduit and needle tubing punctured into together during use intravascular, after conduit fully enters blood vessel, withdraw out pin
Pipe, only by the catheter retaining of softness in the blood vessels so as to carrying out infusion treatment.
However, current remaining needle, needle tubing structure and specification is smaller, and needle tubing is very thin, very soft, insufficient strength, is not easy to be pierced into blood
Pipe, or even bending.
The content of the invention
To be solved in the utility model is existing remaining needle insufficient strength, is not easy to insert the technical problem of blood vessel, there is provided
A kind of intensity is big, easily inserts the remaining needle of blood vessel.
In order to solve technical problem of the present utility model, the utility model is achieved through the following technical solutions：It is a kind of
Remaining needle, including needle tubing component and infusion tube set, the needle tubing component include sheath 1, needle tubing 2, conduit 3, catheter block 5, every
From plug 6 and needle stand 8；The sheath 1 is enclosed on the needle tubing 2, and the catheter block 5 is connected by conduit wedge 4 with conduit 3, described
Batching pig 6 is arranged in the catheter block 5, and described one end of needle tubing 2 is through the batching pig 6 and extend into the conduit 3, separately
One end is fixed on the needle stand 8；The needle tubing 2 is provided with side opening 21, and the top of needle tubing 2 is provided with pin mouth 22, the side opening
21 opening directions are different from the bevel direction of pin mouth 22.
Preferably, the opening direction of side opening 21 differs 90 degree with the bevel direction of pin mouth 22, now column strength highest, no
Easy bending, effect are best.
Preferably, the needle tubing component also includes Needlestick prevention device 7, and the Needlestick prevention device 7 is fixed on the batching pig 6
Below, it is arranged in the catheter block 5, the needle tubing 2 extends there through.
Preferably, the infusion tube set is connected with the needle tubing component, and the infusion tube set includes extension tube 12
With infusion interface 10, described one end of extension tube 12 is connected with catheter block 5, and the other end is connected with the infusion interface 10.
Preferably, the extension tube 12 is provided with occluding device 9.
Preferably, the occluding device 9 is one-hand clip.
Preferably, the infusion interface 10 is positive pressure connector, needleless joint, threeway, two logical or calparine caps.
Preferably, the infusion interface 10 is provided with end cap 11, for fungi-proofing, clean hygiene.
Compared with prior art, the beneficial effect of the utility model acquisition is：
A kind of remaining needle provided by the utility model, the side opening opening direction on needle tubing and pin mouth bevel direction are arranged on
Different directions, strengthen the intensity of needle tubing bevel direction.Traditional remaining needle, needle tubing side opening are in one together with needle tubing pin mouth inclined-plane
Direction, it is to provoke piercing blood vessel upwards with bevel direction when nurse operation, side opening is the weak link of whole needle tubing, tradition
Side opening design so that column strength is inadequate, causes needle tubing to be not easy to be pierced into blood vessel, easy bending.And the utility model takes needle tubing
Upper-side hole opening direction is arranged on the design of different directions with pin mouth bevel direction, and then strengthens the strong of needle tubing bevel direction
Degree, solves needle tubing and is not easy to be pierced into blood vessel, the technical problem of easy bending.A kind of remaining needle provided by the utility model, provided with anti-
Needling device, is stabbed and cross-infection by mistake caused by being avoided that puncture needle, simple and compact for structure, easy to use, accommodation
Extensively, securely and reliably.

Embodiment
With reference to the accompanying drawings and examples, the utility model is described in further detail.
Referring to accompanying drawing 1, a kind of remaining needle, including needle tubing component and infusion tube set, the needle tubing component include sheath 1,
Needle tubing 2, conduit 3, catheter block 5, batching pig 6 and needle stand 8；The sheath 1 is enclosed on the needle tubing 2, and the catheter block 5 is by leading
Pipe wedge 4 is connected with conduit 3, and the batching pig 6 is arranged in the catheter block 5, and described one end of needle tubing 2 passes through the batching pig 6
And extend into the conduit 3, the other end is fixed on the needle stand 8；The needle tubing 2 is provided with side opening 21, and the needle tubing 2 pushes up
