Abstract
The utility model discloses a kind of syringe needle slip-off preventing transfusion device, belong to the technical field of medical apparatus and instruments.According to the technical scheme that this utility model provides, described syringe needle slip-off preventing transfusion device comprises transfusion device body and is arranged on the slip-off preventing elater of transfusion device feed liquor inner needle wall, slip-off preventing elater inserts mouth of infusion bottle plug inside when infusing with transfusion device feed liquor syringe needle, form clip after getting loose, transfusion device is fixed in transfusing container port plug by feed liquor syringe needle.The risk that when this utility model can be avoided infusing, transfusion device feed liquor syringe needle comes off, wide accommodation, cost is low, safe and reliable.
Description
Technical field
This utility model relates to a kind of transfusion device, and especially a kind of syringe needle slip-off preventing transfusion device, belongs to the technical field of medical apparatus and instruments.
Background technology
In infusion process, Chang Fashengyin patient is not intended to that mesosome is dynamic or unconscious body is dynamic causes transfusion device feed liquor pin to be pulled out, and then the ground pollution that drops.Patient need change transfusion device in time when ward, causes waste, and comparatively bothers.If patient in transhipment distance, then cannot change transfusion device, need temporary close transfusion device, wait transhipment to complete replacing, often because the waiting time is after causing venous detaining needle to block for a long time, need pull out and again have an acupuncture treatment, not only wasting but also bring misery to patient.
Summary of the invention
The purpose of this utility model overcomes the deficiencies in the prior art, provides a kind of syringe needle slip-off preventing transfusion device, reduce transfusion device and extract in transfusion, and its structure is simple, and easy to use, cost is low, safe and reliable.
According to the technical scheme that this utility model provides, described syringe needle slip-off preventing transfusion device, comprise transfusion device body and be arranged on the slip-off preventing elater of transfusion device feed liquor inner needle wall, inner needle wall passage is set in described transfusion device feed liquor inner needle wall in order to embedding fixing slip-off preventing elater.Described inner needle wall passage is divided into stationary conduit, ejection gap, sliding channel and control gap four sections by needle tip successively to Aculeata.Described slip-off preventing elater is divided into fixing elater, protrusion arc elater and slip elater three sections by needle tip successively to Aculeata.By fixing, elater is embedding to be fixed in stationary conduit described slip-off preventing elater.Described protrusion arc elater is exposed to outside feed liquor inner needle wall by ejecting gap.Described slip elater is embedded in sliding channel, and slip elater tail end sidewall is exposed to the connection of control gap internal fixtion and arranges control knob, can control the unidirectional slip in inner needle wall passage of slip elater by regulable control button.
The total length of described slip-off preventing elater is slightly less than the total length of inner needle wall passage, protruding arc elater under naturalness keeps arc to protrude by natural resiliency, when regulable control button slides to the end of inner needle wall passage, protrusion arc elater arc protrudes to be straightened and slips in inner needle wall passage.
Advantage of the present utility model: avoid transfusion device to extract in transfusion, its structure is simple, and easy to use, cost is low, safe and reliable.

Description of reference numerals: 1-transfusion device body, 10-feed liquor inner needle wall, 11-stationary conduit, 12-eject gap, 13-sliding channel, 14-controls gap, 2-control knob, 3-slip-off preventing elater, 31-fixes elater, 32-protrudes arc elater and 33-slip elater.
Detailed description of the invention
Below in conjunction with concrete drawings and Examples, the utility model is described in further detail.
As shown in Figures 1 and 2, described a kind of syringe needle slip-off preventing transfusion device, comprises transfusion device body 1 and is arranged on the slip-off preventing elater 3 of transfusion device feed liquor inner needle wall 10.Inner needle wall passage is set in described transfusion device feed liquor inner needle wall 10 in order to embedding fixing slip-off preventing elater 3.Described inner needle wall passage is divided into stationary conduit 11, ejection gap 12, sliding channel 13 and control gap 14 4 sections by needle tip successively to Aculeata.Described slip-off preventing elater 3 is divided into fixing elater 31 by needle tip successively to Aculeata, protrudes arc elater 32 and slip elater 33 3 sections.By fixing, elater 31 is embedding to be fixed in stationary conduit 11 described slip-off preventing elater 3.Described protrusion arc elater 32 is exposed to outside feed liquor inner needle wall 10 by ejecting gap 12.Described slip elater 33 is embedded in sliding channel 13, and slip elater 33 tail end sidewall is exposed to the connection of control gap 14 internal fixtion and arranges control knob 2, can control slip elater 33 unidirectional slip in inner needle wall passage by regulable control button 2.
The total length of described slip-off preventing elater 3 is slightly less than the total length of inner needle wall passage, protrudes arc elater 32 and keep arc to protrude by natural resiliency under naturalness.When regulable control button 2 slides to the end of inner needle wall passage, protrusion arc elater 32 arc protrudes to be straightened and slips in inner needle wall passage.
Concrete, described slip-off preventing elater 3 is tinsel, and before transfusion device feed liquor syringe needle inserts infusion vessel, regulable control button 2 slides to the end of inner needle wall passage.Now, protrusion arc elater 32 arc protrudes to be straightened and slips in inner needle wall passage, and the arc convex protruding arc elater 32 disappears, and transfusion device feed liquor syringe needle easily inserts in the bottle stopper of infusion vessel.Unclamp control knob 2, protrude arc elater 32 and keep arc to protrude at type infusion bottle plug upper space by natural resiliency.
In transfusion, if transfusion device is pulled by external force, protrude arc elater 32 upwards stressed, arc protrudes and is held distortion, and slip elater 33 has the trend of upward sliding, and because control knob 2 is fixedly connected with slip-off preventing elater 3, slip elater 33 cannot upward sliding.Under the arc protruding arc elater 32 protrudes position-limiting action, transfusion device feed liquor syringe needle cannot deviate from transfusion device bottle stopper.
When infusion-completed needs to change fluid infusion, regulable control button 2 slides to the end of inner needle wall passage, and now, protrusion arc elater 32 arc protrudes to be straightened and slips in inner needle wall passage, the arc convex protruding arc elater 32 disappears, and infusion vessel bottle stopper easily extracted by transfusion device feed liquor syringe needle.
In a word: this utility model is regulated the arc protrusion protruding arc elater 32 by control knob 2, control the plug or fixing of transfusion device feed liquor syringe needle, in transfusion, avoid transfusion device to extract, replacing fluid infusion is unaffected, and structure is simple, easy to use, wide accommodation, cost is low, safe and reliable.
