Abstract
The utility model relates to a novel venous indwelling needle. The novel venous indwelling needle comprises an indwelling needle seat and an indwelling needle sleeve connected with the indwelling needle seat, one end of the indwelling needle, connected with the indwelling needle sleeve, is arranged into a slope which is inclined towards the axis of the indwelling needle sleeve, and a position of the slope, connected with the indwelling needle sleeve, has the same diameter as the indwelling needle sleeve. The novel venous indwelling needle is simple in structure and safe to use, the one end of the indwelling needle seat, connected with the indwelling needle sleeve, is arranged into a slope structure, the condition of bending cannot occur, infusion is smooth, an inclined angle is formed between the slope and the axis of the indwelling needle sleeve, and therefore skin is unlikely to be compressed to cause pressure sores.
Description
Technical field
This utility model relates to area of medical devices, specifically, relates to a kind of venous detaining needle.
Background technology
Venous detaining needle is called again the trocar, is a kind of medical apparatus and instruments for infusion, is usually used in being heavy patient's rescue, cancer of late stage, patient infusion that venipuncture difficulty is large.At present, venous detaining needle uses increasingly extensive clinically, especially is difficult to cooperate the patient of infusion treatment to use more to the patient of old inconvenient activity, infant and some.But the remaining needle that uses at present, the needle stand a of its sleeve pipe b root is transverse section (as shown in Figure 1), in using the remaining needle process, have following shortcoming: (1) sleeve pipe very easily gives a discount, and affects the unobstructed of liquid input; (2) edge of transverse section compressing skin forms cut channel easily on the skin, cause pressure ulcer; (3) infant is when using venous detaining needle, and great majority are used in head, after remaining needle is extracted, damage easily vein blood vessel, and vein blood vessel is scrapped.
The utility model content
The purpose of this utility model is the problems referred to above of existing for existing venous detaining needle, provide a kind of simple in structure, use safety, the unimpeded Novel intravenous catheter of transfusion.
The technical solution of the utility model is: a kind of Novel intravenous catheter, this venous detaining needle comprises needle seat of remaining needle and is connected the remaining needle sleeve pipe with needle seat of remaining needle, the end that needle seat of remaining needle is connected with the remaining needle sleeve pipe is set to the inclined-plane that tilts to the remaining needle casing axis, and the diameter of this inclined-plane and remaining needle sleeve pipe junction is identical with the diameter of remaining needle sleeve pipe.
The beneficial effects of the utility model are: this utility model is simple in structure, use safety, the end that needle seat of remaining needle is connected with the remaining needle sleeve pipe is set to ramp structure, the situation that can not occur bending, make transfusion unobstructed, and the angle of inclined plane and remaining needle casing axis is to be unlikely to oppress skin and to cause pressure ulcer.
Description of drawings
Accompanying drawing 1 is the structural representation of common venous detaining needle;
Accompanying drawing 2 is the structural representation of this utility model specific embodiment.
The specific embodiment
The specific embodiment: as shown in Figure 2, a kind of Novel intravenous catheter, this venous detaining needle comprises needle seat of remaining needle 1 and is connected remaining needle sleeve pipe 2 with needle seat of remaining needle 1, the end that needle seat of remaining needle 1 is connected with remaining needle sleeve pipe 2 is set to the inclined-plane 3 that tilts to the remaining needle casing axis, and the diameter of this inclined-plane 3 and remaining needle sleeve pipe junction is identical with the diameter of remaining needle sleeve pipe 2.
Claims (1)
