Technical field

The utility model relates to the equipment of medication injections, specifically, is the anti-skidding syringe needle of single intravenous infusion.

Background technology

Venous transfusion is to utilize atmospheric pressure and fluid pressure principle to be inputted internal by vein by a large amount of sterile liquids, electrolyte, medicine Method.

By substantial amounts of liquid, electrolyte or blood by being injected intravenously referred to as phleboclysis.Because of the position injected and transfusion not With, Peripheral vein infusion, peri-operative central venous infusion, high nutrition infusion (TPN) and blood transfusion etc. can be divided into.

Venous transfusion connects human vas and extraneous infusion niidl is essential.

Patent document CN 204246613 U (applying date 2014.11.20) discloses a kind of children and uses environment-friendlycomfortable comfortable type venous transfusion Fixing torr.Having base body, base body is to use wood pulp or paper pulp to make, and it has the vertical flanging of end face and surrounding and surrounds, described End face, by asking metacarpus and torr wrist to constitute, is provided with four finger recesses on torr metacarpus, is provided with 2-3 bar at torr wrist the most anti-skidding Groove, and ask wrist slightly below to hold in the palm metacarpus；It is positioned at torr metacarpus side at base body end face and asks wrist side to be respectively provided with an eyelet, Equipped with gluing fastener-type binding strap in each eyelet.

The utility model environmental protection, uses comfort and convenient, and the syringe needle changing of the relative positions that when can effectively prevent child infusion, movability causes is made Become liquid to transport to outside blood vessel, leakage, swelling pain etc. occur, mainly uses when intravenous transfusion into hand of child.

Patent document CN 204601261 U (applying date 2015.05.13) discloses a kind of intravenous infusion apparatus needle protection set.Bag Including protection set body, protection set body is hollow structure, also includes pedestal and handle, and protection set body lower end is solid with pedestal upper end Fixed connection, handle is fixing with pedestal side to be connected, and has through hole in pedestal, and the side of protection set body has in the linear pattern of two ends Between the slideway of camber.

The beneficial effects of the utility model are: use protection set to protect syringe needle for transfusion device, solve existing syringe needle The difficult problem that head is easily hurted sb.'s feelings.

Above-mentioned patent document has the disadvantage that 1, the most anti-skidding 2, puncture failure rate is high.

Utility model content

The utility model purpose is intended to provide the anti-skidding syringe needle of single intravenous infusion that a kind of puncture failure rate is low.

For realizing above-mentioned technical purpose, the technical solution adopted in the utility model is as follows:

The anti-skidding syringe needle of single intravenous infusion, including needle handle, is positioned at the conduit of needle handle rear end, is positioned at the syringe needle of needle handle front end, Described needle handle front end edge syringe needle direction is provided with support column.

Using the utility model of technique scheme, the traditional needle angle of venipuncture is 15 °～30 °, through clinical practice Find that increasing the needle angle between syringe needle and skin is more easy to puncture, and owing to angle is big, reduced by the time of skin corium, can Alleviate pain that inserting needle causes or reach painless.

The technical program is by needle handle extension supporting post, on the one hand, increases the friction of hand and needle handle, has reached skidproof effect, Improve puncture success rate, on the other hand, by support column, more preferably grasp the needle angle punctured, decrease and pass through skin corium Time.

Limiting further, described needle handle front end is provided with at least two adjusting grooves, and described adjusting grooves is provided with internal thread, described Support column includes the first support column for inserting adjusting grooves, is positioned at the second support column of the first support column rear end, described first Support column is provided with and the external screw thread of internal thread coupling.

Needle handle front end is provided with at least two adjusting grooves, it is possible to adapt to different size of hand-type, makes use convenient, anti-skidding effect Fruit is more preferably.

Limiting further, also include that strapping, described needle handle are fan shape, described needle handle is radially provided with for connecting strapping Manhole, is positioned at the snap close seat of manhole right, and described strapping left end connects manhole, and its right-hand member connects snap close seat.

Strapping can fixed needle, make syringe needle be unlikely to slide, prevent from injuring patient, easy to use.

Limiting further, described strapping is two elastic bands.

Strapping is two elastic bands, makes fixing more firm, and strapping has elasticity, can allow patient comfort.

Limiting further, described adjusting grooves is three, and two-by-two at a distance of 3-5cm, described first supports column length 1cm, described Second supports column length 2cm.

Being provided with three adjusting grooves, use convenient, three grooves enough adapt to the hand-type of all sizes, and structure is simplified.

Compared to existing technology, simple in construction, anti-skidding, puncture success rate is high for the utility model.
