Abstract
The utility model discloses a safety vein needle which comprises a puncture needle, a needle base connected with the tail end of the puncture needle, a shell used for containing the puncture needle and the needle base and a guide pipe connected with the needle base. The two sides of the needle base are respectively connected with a butterfly wing and sliding ways are formed in the two sides of the shell and matched with the butterfly wings. The safety vein needle is characterized in that a limiting clamping tongue is arranged on the upper portion of the needle base; a first limiting clamping groove and a second limiting clamping groove are formed in the portion, close to the outer end, of the shell and the portion, close to the inner end, of the shell respectively; when the limiting clamping tongue is clamped in the first limiting clamping groove, the puncture needle stretches out of the shell; when the limiting clamping tongue is clamped in the second limiting clamping groove, the puncture needle is contained in the shell. According to the safety vein needle, the use safety of the vein needle is effectively improved.
Description
Technical field
this utility model relates to a kind of medical apparatus and instruments, is specifically related to a kind of safety intravenous needle.
Background technology
intravenous needle is a kind of conventional medical apparatus and instruments, mainly supplies medical institutions and disposable infusion (blood) device, disposable sterilized syringe to support the use, and is mainly used to be clinically used as venous transfusion, blood transfusion or employing.Disposable use intravenous needle is mainly made up of needle tubing, needle handle, flexible pipe, needle stand, protective cover etc.; intravenous needle in use, first pulls out protective cover, exposes needle tubing; then use needle tubing to transfuse blood or the operation such as employing; after end of operation, then extract needle tubing, intravenous needle is placed into the sequestration site of appointment; but needle tubing is exposed in this process; lack corresponding protective measure, medical personnel very likely can be accidentally injured by syringe needle, thereby cause cross infection.
the problem existing for intravenous needle, many corrective measures are there are on the market, patent documentation WO2012032378A1, WO2010038844A1, CN03102395.9, CN201110308424.0, CN201080008965.5 all relates to the protection scheme of intravenous needle, what wherein WO2010038844A1 recorded is a kind of anti-acupuncture system, housing unit wherein has main element, main element has far-end, cylindrical shell between near-end and far-end and near-end, cylindrical shell is the major length part of main element, near-end and far-end are formed with respectively hole, shank is made up of upper cover and lower cover, upper cover and lower cover are by pair of flexible chain connection, the upper end of flexible hinge connects the far-end of upper cover and the far-end of lower end connection lower cover, make the operation that upper cover and lower cover can be between closure and open position.To use the venous needle having been polluted, recyclable retraction is in shank, and carries out blocking with the line of rabbet joint forming between upper cover and the opposite edges of lower cover and make intravenous needle be positioned, in the cylindrical shell of safe needle sleeve, to want to reach with this object of safe retraction intravenous needle.
find in practice, more or less all there is defect in the vein needle protection structure using at present, for example not firm for used syringe needle blocking, easily causes syringe needle to be exposed to outside protection structure, and still still may accidentally injure medical personnel causes cross infection.
Summary of the invention
this utility model object is to provide a kind of safety intravenous needle, by the improvement to structure, has improved the safety in utilization of intravenous needle.
the technical solution of the utility model is: a kind of safety intravenous needle, comprise puncture needle, the needle stand being connected with puncture needle tail end, for the conduit that holds the shell of puncture needle and needle stand and be connected with needle stand, needle stand both sides are connected with respectively the butterfly wing, be engaged in shell both sides with the described butterfly wing and offer respectively chute, described needle stand top offers spacing block tongue, on described shell, nearly outer end place and inner place offer respectively the first spacing draw-in groove and the second spacing draw-in groove, in the time that spacing block tongue is arranged in the first spacing draw-in groove, described puncture needle stretches out described shell, in the time that spacing block tongue is arranged in the second spacing draw-in groove, described puncture needle is accommodated in described shell.
further technical scheme, described shell is made up of upper casing and lower casing, engagement connection between described upper casing and lower casing.
further technical scheme, described shell outer end is also connected with protective sleeve.
further technical scheme, the described butterfly wing is provided with non-slipping block.
the utility model has the advantages that: this utility model by arranging spacing block tongue on needle stand, be engaged in nearly outer end on shell with spacing block tongue and offer respectively first and second spacing draw-in groove with inner place, in the time that spacing block tongue is stuck in the first spacing draw-in groove, puncture needle stretches out in shell, can normally use, in the time that spacing block tongue is stuck in the second spacing draw-in groove, puncture needle is accommodated in shell, prevent accidental injury, thereby improved the safety in utilization of intravenous needle.
Accompanying drawing explanation
below in conjunction with drawings and Examples, this utility model is further described:
fig. 1 is the schematic diagram of this utility model embodiment mono-;
fig. 2 is the cutaway view of this utility model embodiment mono-.
wherein: 1, puncture needle; 2, needle stand; 3, shell; 4, conduit; 5, the butterfly wing; 6, chute; 7, spacing block tongue; 8, the first spacing draw-in groove; 9, the second spacing draw-in groove; 10, protective sleeve.
The specific embodiment
embodiment mono-: referring to Fig. 1, shown in 2, a kind of safety intravenous needle, comprise puncture needle 1, the needle stand 2 being connected with puncture needle 1 tail end, for the conduit 4 that holds the shell 3 of puncture needle 1 and needle stand 2 and be connected with needle stand 2, needle stand 2 both sides are connected with respectively the butterfly wing 5, the described butterfly wing 5 is provided with non-slipping block, be engaged in shell 3 both sides with the described butterfly wing 5 and offer respectively chute 6, described needle stand 2 tops offer spacing block tongue 7, on described shell 3, nearly outer end place and inner place offer respectively the first spacing draw-in groove 8 and the second spacing draw-in groove 9, in the time that spacing block tongue 7 is arranged in the first spacing draw-in groove 8, described puncture needle 1 stretches out described shell 3, in the time that spacing block tongue 7 is arranged in the second spacing draw-in groove 9, described puncture needle 1 is accommodated in described shell 3.
described shell is made up of upper casing and lower casing, is respectively equipped with fixture block and the draw-in groove of engaging use on upper casing and lower casing, or other dismountable engagement connection structure, makes engagement connection between upper casing and lower casing.
