Description
Technical field
The utility model is related to a kind of remaining needles, and in particular to a kind of to facilitate the fixed remaining needle of inserting needle.
Background technology
Venous detaining needle is also known as venous catheter needle.The building block of core includes that leading for endovascular softness can be retained in
Pipe, and the guiding puncture needle core of stainless steel.Conduit and needle core punctured into together during use it is intravascular, when conduit fully enters
After blood vessel, clinically correct operating method is：15 ~ 30 degree of angle inserting needles of the needle wing are held, inserting needle is preferably slow, when seeing blood back, reduces angle 5
~ 15 degree, then inserting needle 2mm, to ensure hose in the blood vessels, needle core can not be extracted immediately after seeing blood back, it is necessary to it reduces angle and send needle,
May be at this time draw point in the blood vessels, needle core is withdrawn out, only by soft catheter retaining in the blood vessels so as to carry out infusion treatment.
The application of venous detaining needle is the preferable method of clinical transfusion, on the one hand can mitigate infant and be brought because scalp acupuncture punctures repeatedly
Pain, suitable for the patient of long-term infusion, on the other hand also mitigate the workload of clinical nurse, improve nursing staff and work effect
The advantages that rate.But it after the completion of clinical vein remaining needle operation inserting needle, needs entire remaining needle being fixed on patient infusion position, again
Because the transparent threeway of remaining needle is cylinder, pad pasting or Elastic bandage are fixed, and general indwelling time is longer, therefore current remaining needle
Contour structures necessarily lead to stress injury to skin, such as press red, pit, ulceration, pressure sore, indwelling even will appear when serious
Needle volume for common scalp needle for infusion is bigger than normal, also because the limitation of structure causes needle angle big, it is difficult to control
The defects of.

Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
It clearly and completely describes, it is clear that the described embodiments are only a part of the embodiments of the utility model rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without making creative work
All other embodiments obtained shall fall within the protection scope of the present invention.
As shown in Figure 1, the utility model includes transparent threeway 1, pasting board 2 and positive pressure connector 9, transparent threeway 1 passes through extension
Pipe 13 is connected with positive pressure connector 9, as shown in figure 4, the bottom surface of transparent threeway 1 is flat pattern, as shown in Figures 2 and 3, pasting board 2
Bottom surface is equipped with viscous layer 4, and 4 bottom surface of viscous layer is equipped with anti-sticking pad pasting 6, and the side on 2 surface of pasting board is equipped with fixed patch 5,2 positive table of pasting board
Face longitudinal midline position sets shallow slot 3, and shallow slot 3 is gradually lower along inserting needle direction, ecto-entad height, the bottom surface of transparent threeway 1
Longitudinal midline position is provided with the protrusion 7 being adapted to shallow slot 3, and 9 bottom surface of positive pressure connector is flat.
In use, selection blood vessel, pasting board 2 is placed on patient needs to have an acupuncture treatment the rear side of inserting needle, the center line of shallow slot 3 preferably with
Acupuncture treatment point is conllinear, and then transparent threeway 1 is placed in shallow slot 3 and (does not need to assemble, the condition of 2 thickness low LCL of pasting board assembling）It holds
The needle wing 11 starts inserting needle, is angled requirement when operating inserting needle, when encountering specific blood vessels needs to be close to skin inserting needle, inserting needle angle
When degree needs minimum, the bottom surface of transparent threeway 1 is flat pattern, reduces needle angle, pasting board 2 is located at transparent threeway 1 and people
It between skin, avoids transparent threeway 1 directly and skin contact, reduces the frictional force of inserting needle, greatly facilitate the operation of inserting needle,
The shallow slot 3 of pasting board 2 and the protrusion 7 of transparent threeway 1 coordinate in inserting needle, and shallow slot 3 gradually becomes along inserting needle direction, ecto-entad height
It is low, ensure the direction of inserting needle to a certain extent, assist personnel inserting needle after the completion of inserting needle, is torn anti-sticking from 2 bottom of pasting board
Pasting board 2 is tightly sticked on patient skin by pad pasting 6 by viscous layer 4, then by the fixed patch 5 of 2 surface side of pasting board from transparent
The top of threeway 1 is pulled by the lateral opposite side, and in threeway both sides plasticity, is attached on 2 opposite side of pasting board or patient skin
Can, so as to which transparent threeway 1 is fixed on pasting board 2, as shown in figure 5, being cased with aerofoil profile patch 12, aerofoil profile on the outside of the tube wall of extension tube 13
Patch 12 is located at extension tube 13 and 9 junction of positive pressure connector, and after transparent threeway 1 fixes, aerofoil profile of tearing pastes the pad pasting of 12 bottom surfaces,
Aerofoil profile patch 12 is attached on patient skin, so as to fixed positive pressure connector 9；The bottom surface of transparent threeway 1 is flat pattern, by transparent three
Logical 1 contact with the line of patient's script and becomes face and contact, and reduction pressure is alleviated and presses against sense.
In order to ensure that transparent threeway 1 is located at 2 top of pasting board, prevent the transparent threeway 1 after fixing from shifting, 3 inserting needle side of shallow slot
Most inner side is provided with postive stop baffle 10, when the protrusion 7 of transparent 1 lower section of threeway is contacted with postive stop baffle 10 for transparent threeway 1 most
Greatly into needle stroke；Fixed patch 5 fixes patch 5 for three foldings, facilitates fixation under the premise of inserting needle is not interfered；Anti-sticking 6 outer side edges of pad pasting
Edge is provided with pad pasting and tears first 8, and pad pasting is torn there are two first 8, and two pad pastings tear first 8 and anti-sticking pad pasting 6 is divided into two parts, tear
When, pad pasting tears first 8 and tears round about, convenient after the completion of inserting needle, and anti-sticking pad pasting 6 is torn under the premise of not moving pasting board 2；
Not easily shifted transparent threeway 1 after the completion of inserting needle, for this purpose, two pad pastings are torn into first 8 left and right sides for being separately positioned on shallow slot 3,
Transparent threeway 1 will not be touched by tearing when pad pasting tears first 8.
