Abstract
This case is related to a kind of indwelling needle lock, comprising: protective cover has for protecting the anti-extrusion indent for puncturing position and the first connecting plate and the second connecting plate positioned at the anti-extrusion indent two sides；Threeway card slot is fixedly connected on first connecting plate；Fixing belt is connected to first connecting plate and the second connecting plate；Tube sealing positive pressure folder, is located at close to the side of second connecting plate.The remaining needle fixer structure of this case is simple, can be avoided site of puncture infection, and fixation when being infused to patient, mitigates patient's pain；The tube sealing positive pressure folder of this case simultaneously can play the risk for preventing blood back flow from causing remaining needle plugging very well.
Description
Technical field
The utility model belongs to medical instruments field more particularly to a kind of indwelling needle lock.
Background technique
Nursing staff using remaining needle to patient when being infused at present, after piercing needle is pierced into patient's blood vessel, in order to
It avoids site of puncture from infecting, places sterilized cotton ball in site of puncture mostly, blend compounds cloth is fixed, and such mode of operation is number
It is tired, and fixed effect is insecure, brings unnecessary pain to patient sometimes.
Utility model content
Aiming at the deficiencies in the prior art, the purpose of this utility model is to provide one kind to carry out indwelling to patient
Needle can effectively avoid site of puncture from infecting and play the indwelling needle lock of protective action when being infused, stayed by positive pressure clip
Positive pressure is provided when setting needle tube sealing, prevents remaining needle from generating the problems such as adverse current is to cause plugging when not being infused.
To achieve the above object, the technical solution of the utility model is as follows:
A kind of indwelling needle lock comprising:
Protective cover has and punctures the anti-extrusion indent of position and positioned at the first connection of the anti-extrusion indent two sides for protecting
Plate and the second connecting plate；
Threeway card slot is fixedly connected on first connecting plate；
Fixing belt is connected to first connecting plate and the second connecting plate；
Tube sealing positive pressure folder, is located at close to the side of second connecting plate.
Preferably, the indwelling needle lock, wherein the slot of the notch of the threeway card slot and the anti-extrusion indent
Mouth is oppositely arranged.
Preferably, the indwelling needle lock, wherein the threeway card slot includes a main card position and a vice card
Position.
Preferably, the indwelling needle lock, wherein the fixing belt is elastic force non-woven fabrics.
Preferably, the indwelling needle lock, wherein tube sealing positive pressure folder include integrally formed fixture block,
Closing piece and card hole.
Preferably, the indwelling needle lock, wherein the tube sealing positive pressure clamp surface is equipped with anti-skidding raised line.
The beneficial effects of the utility model are: the remaining needle fixer structure of this case is simple, it can when being infused to patient
It avoids site of puncture from infecting, and fixation, mitigates patient's pain；The tube sealing positive pressure folder of this case simultaneously can be played very well and be prevented
Blood back flow causes the risk of remaining needle plugging.
Detailed description of the invention
Fig. 1 is the shaft side figure of indwelling needle lock.
Fig. 2 is the structural schematic diagram of protective cover and fixing belt in indwelling needle lock.
Fig. 3 is the structural schematic diagram of tube sealing positive pressure folder in indwelling needle lock.
Specific embodiment
The following describes the utility model in further detail with reference to the accompanying drawings, to enable those skilled in the art referring to explanation
Book text can be implemented accordingly.
Referring to Figure 1-3, illustrate the indwelling needle lock of one embodiment of this case comprising:
Protective cover 1 has and punctures the anti-extrusion indent 101 of position and positioned at anti-extrusion 101 two sides of indent for protecting
First connecting plate 102 and the second connecting plate 103；
Threeway card slot 2 is fixedly connected on the first connecting plate 102；
Fixing belt 3 is connected to the first connecting plate 102 and the second connecting plate 103；
Tube sealing positive pressure folder 4, is located at close to the side of the second connecting plate 103.
Wherein, the notch of threeway card slot 2 and the notch of anti-extrusion indent 101 are oppositely arranged.
Wherein, threeway card slot 2 includes a main card position 201 and a vice card position 202.
Wherein, fixing belt 3 is elastic force non-woven fabrics.
Wherein, tube sealing positive pressure folder 4 includes that the integrally formed tube sealing positive pressure that is located at presss from both sides the fixture block 401 of 4 upper ends, is located at tube sealing
The closing piece 402 in 4 left side of positive pressure folder and the card hole 403 inside tube sealing positive pressure folder 4.Fixture block 401 is pressed by finger to be bent directly
To being caught on by closing piece 402, the contraction of card hole 403 becomes smaller, and the bottom end squeezing tube of fixture block 401 is to reach tube sealing effect.
Wherein, tube sealing positive pressure presss from both sides 4 surfaces and is equipped with anti-skidding raised line 404, in order to one-handed performance.
In use, the anti-extrusion indent 101 of protective cover 1 is covered in and punctures position and indwelling after retained needle puncture sets pipe success
Above needle hose needle stand, the fixing belt 3 for connecting protective cover 1 is relatively fixed by anti-extrusion indent 101.It, will after retention needle infusion
Remaining needle threeway be fixed on threeway card slot 2 (can as needed by the fixed threeway main body in main card position 201, vice card position 202 it is fixed with
Threeway connection infusion tube), finally by tube sealing positive pressure folder 4 clamp transfusion catheter puncture position end generate the anti-Hemostatic Oral Liquid of positive pressure and
Liquid countercurrent.
It is not only in the description and the implementation although the embodiments of the present invention have been disclosed as above
Listed utilization, it can be applied to various fields suitable for the present invention completely, for those skilled in the art,
Other modifications may be easily implemented, therefore without departing from the general concept defined in the claims and the equivalent scope, this reality
It is not limited to specific details and legend shown and described herein with novel.
