Description
Technical Field
The utility model relates to the technical field of medical equipment, in particular to a wall-sticking prevention venous indwelling needle.
Background
The venous indwelling needle is also called a trocar and is widely applied to clinical workers as a substitute product of a scalp needle, has the advantages of simple operation, small stimulation to tissues, long indwelling time, difficult puncture of blood vessels and the like, can reduce the times of venous puncture, relieve the pain of patients and the workload of nursing, reduce the vein injury, reduce the infection rate of the tube, and is beneficial to clinical medication and rescue of the patients.
After the needle puncture is kept somewhere to clinical vein, nurse's conventionality need use the fixed needle of keeping somewhere of transparent dressing, when using the fixed vein of transparent dressing to keep somewhere needle file afterbody white isolation stopper, can give its decurrent pressure, according to lever principle, it takes place the bending in the blood vessel to keep somewhere the needle, the needle point department of syringe needle can slightly upwards perk, the needle point contacts the vascular wall and leads to the phenomenon that liquid does not drip, in the face of this kind of condition, nurse often need pull the pjncture needle backward through changing fixed transparent dressing or using medical adhesive tape and make to keep somewhere the needle and move towards the unanimity with the blood vessel and solve, but so not only can bring the discomfort for the patient, the needle retention time is obviously shortened is kept somewhere to the vein, aggravate patient's economic burden and added nurse's work load. Therefore, the utility model provides a prevent sticking to wall vein and keep somewhere needle to solve the above-mentioned problem that proposes.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a prevent pasting wall vein and keep somewhere needle to solve the problem that proposes among the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme:
the utility model provides a prevent pasting wall vein and stay needle, includes needle file, needle wing and Y type interface, the lower extreme of needle file is equipped with puncture needle tubing, puncture needle tubing's lower extreme is equipped with the puncture inclined plane, puncture needle tubing's outside cover is equipped with keeps somewhere the needle sleeve pipe, it is equipped with the sleeve pipe inclined plane to keep somewhere the sheathed tube lower extreme of needle, puncture needle tubing's that the inclined plane of puncture corresponds surface runs through and is equipped with first side opening, it is equipped with the second side opening to keep somewhere the sheathed tube surface of needle.
As a further proposal of the utility model, the inclined direction of the casing inclined plane at the lower end of the indwelling needle casing is opposite to that of the puncture inclined plane at the lower end of the puncture needle casing.
As the utility model discloses scheme further still, second side opening and first side opening all set up to the ellipse, the size of second side opening and first side opening is the same completely, just the center of first side opening and second side opening is on same straight line.
As the utility model discloses still further scheme, first side hole major axis diameter is 2 times of keeping somewhere needle cannula diameter, and the minor axis diameter is 1/2 of keeping somewhere needle cannula diameter.
Compared with the prior art, the beneficial effects of the utility model are that:
1. the utility model discloses during the use, the casing pipe inclined plane can avoid when medical personnel keeps somewhere the needle with the fixed vein of transparent dressing puncture inclined plane opposite direction hug closely the vascular wall and lead to the phenomenon that liquid does not drip, and first side opening and second side opening not only can increase the blood return volume when the vein keeps somewhere the needle and returns blood and confirm, make things convenient for the blood return to confirm, but also can guarantee when puncture needle tubing takes place the infusion not smooth, and liquid can pass through from first side opening and second side opening to the practicality of needle is kept somewhere to the vein has been increased.
2. The utility model has the characteristics of simple structure, it is convenient to make.

In the figure: 1. a needle seat; 2. a needle wing; 3. a Y-type interface; 4. puncturing a needle tube; 5. an indwelling needle cannula; 6. puncturing the inclined plane; 7. a first side hole; 8. a second side hole; 9. a beveled surface of the sleeve.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Please refer to fig. 1-3, in the embodiment of the utility model, an anti-wall-sticking vein indwelling needle, including needle file 1, needle wing 2 and Y type interface 3, the lower extreme of needle file 1 is equipped with puncture needle pipe 4, puncture needle pipe 4's lower extreme is equipped with puncture inclined plane 6, puncture needle pipe 4's outside cover is equipped with indwelling needle sleeve 5, indwelling needle sleeve 5's lower extreme is equipped with sleeve pipe inclined plane 9, indwelling needle sleeve 5's length is less than puncture needle pipe 4's length, puncture needle pipe 4's that puncture inclined plane 6 inclined plane corresponds surface runs through and is equipped with first side hole 7, indwelling needle sleeve 5's surface is equipped with second side hole 8.
