Abstract

The utility model relates to an arc-shaped venipuncture remaining needle suitable for the external jugular vein and the greater saphenous vein, which belongs to the field of medical apparatus and instruments. The arc-shaped venipuncture remaining needle comprises a metal puncture needle core with a needle handle, and a flexible plastic sleeve capable of being sheathed outside the metal puncture needle core, wherein a nipple connector of an injector is arranged at the tail end of the needle core and the sleeve. In order to change the structural angles of a needle point and a needle rod, the front one-third section, the middle one-third section or the overall section of the metal needle core is bent into the arc shape and can be smoothly pulled out from a straight sleeve, the inclined plane of the needle point of the arc-shaped needle core faces to the arc core side, and the inclined plane of the metal needle core exactly passes through the round head of the sleeve. The needle point faces to the arc core side so as to enable the front section of the needle point and the vein to be parallel during the puncturing process, and the inclined plane of the metal needle core exactly passes through the round head of the sleeve so as to enable the sleeve to be led to the vein through the needle core. The utility model aims to provide the venipuncture remaining needle which can be held conveniently, effectively avoid the perforation of the rear wall of the blood vessel, and be convenient for the remaining. The arc-shaped venipuncture remaining needle is particularly suitable for the puncture of the proximal end of the tibia medial condyle of the external jugular vein and the middle section of the external jugular vein.

Description

Arc venipuncture remaining needle
Technical field
This utility model relates to a kind of medical apparatus and instruments.Particularly a kind of arc venipuncture remaining needle that is suitable for external jugular vein and great saphenous vein puncture indwelling.
Background technology
The venipuncture remaining needle that uses on the market was straight type pin in the past, during venipuncture, need directly advance directly to move back, and very easily wore out the vein rear wall, caused puncture failure.When the puncture of external jugular vein and great saphenous vein, even by experience person's puncture is arranged, but because angle of mandible or tuberosity of tibia,internal, still can not change shank and venous angle to the stopping of shank to parallel.Needle point is still easily worn out blood vessel to subcutaneous extvavasated blood or hematoma, puncture failure rate height.In secular working practice, particularly in operation process, extremity puncture inconvenience or puncture owing to the deep vein puncture complication is many, and need good pricking body position at need, and the cervical region blood vessel has become the first-selection of quick transfusion.The patent No. is 902040391 utility model patent, non-ly directly advances the method for directly moving back for venipuncture provides a kind of, but the novel patent of this kind there is no obvious advantage when puncture external jugular vein and great saphenous vein.Also there is the people that curved the having a certain degree of remaining needle carried out outer or other venipunctures of neck.And clinical practice confirms, when whole remaining needle is curved the angle that is certain and punctures, and the nook closing member frangibility, and after puncturing successfully, nook closing member is difficult to be extracted from sleeve pipe.
Summary of the invention
The purpose of this utility model provides a kind of hand-held convenience, can effectively avoid the arc venipuncture remaining needle of wearing out the blood vessel rear wall and conveniently keeping somewhere.
Arc venipuncture remaining needle of the present utility model, constitute by curved metal puncture nook closing member that has needle handle and straight shape sleeve pipe, nook closing member and sleeve pipe tail end have the syringe nipple joint, it is characterized in that: the metal nook closing member first three/one section, in 1/3rd sections or whole nook closing member curved, the nook closing member segmental arc can penetrate, extract soft tube smoothly.
The puncture nook closing member is the stainless steel metal nook closing member of plastic type, and straight shape sleeve pipe is the plastic bushing of plastic type.
The nook closing member inclined-plane of curved metal puncture nook closing member is towards the arc core side, and metal nook closing member inclined-plane is shortly past the sleeve pipe round end.
The nook closing member segmental arc be arranged in the metal nook closing member first three/place or 1/3rd places, or whole nook closing member is the identical arc of radius of curvature.
The technical scheme that its technical problem that solves this utility model adopts is: the straight shape sleeve pipe of curved metal puncture nook closing member overcoat, sleeve pipe handle tail end and needle handle tail end fixedly comprise with duroplasts respectively, the syringe nipple joint, needle handle syringe nipple joint is by piston closes, the nook closing member head end extends for the nook closing member inclined-plane, straight shape sleeve pipe head end extends for the sleeve pipe round end, the structure angle of needle point and shank for a change, with the metal nook closing member first three/one section, in 1/3rd sections or whole nook closing member bending curved, the nook closing member segmental arc can penetrate smoothly, extract soft tube, with the nook closing member inclined-plane of arc nook closing member towards the arc core side, so that when puncture the needle point leading portion parallel with vein, and with metal nook closing member inclined-plane shortly past the sleeve pipe round end, so that nook closing member grip pipe racks is gone into vein, the butterfly wing is attached on the sleeve pipe handle, is convenient to fixed sleeving on skin.
This utility model is specially adapted to the puncture in great saphenous vein tuberosity of tibia,internal proximal part, external jugular vein stage casing, has hand-held reaching and punctures conveniently the advantage that puncture success rate is high.
Description of drawings
Below in conjunction with accompanying drawing this utility model is described in detail.
Fig. 1 is the cutaway view of arc venipuncture remaining needle of the present utility model.
1. sleeve pipes among Fig. 1,2. nook closing member, 3. sleeve pipe handle, 4. needle handle, 5. nook closing member inclined-plane, 6. sleeve pipe round end, 7. the butterfly wing, 8. piston.
The specific embodiment
With reference to accompanying drawing.This utility model comprises directly moulding expects sleeve pipe 1, sleeve pipe handle 3 and curved metal nook closing member 2 and needle handle 4.After nook closing member was put into sleeve pipe, its pinpoint inclined plane 5 had just exposed telescopic round end 6.Sleeve pipe handle and needle handle tail end are covered by duroplasts, leave air chamber, and promptly the syringe nipple joint has piston 8 sealings.The butterfly wing 7 is arranged on the sleeve pipe handle 3.Realize that the purpose of this utility model is by following approach: choose that 1cm place is a point of puncture on the tuberosity of tibia,internal of the mid point of external jugular vein or great saphenous vein.The arc nook closing member is inserted plastic bushing, and can extract smoothly.The routine disinfection point of puncture, hand thumb is held needle handle, and forefinger and middle finger are held the butterfly wing, the nook closing member inclined-plane is thrusted straightly into vein, see blood back after, the needle handle of loweing, make the arc of needle point place section and the vein arc is consistent and on choose vein and enter 0.5cm again, the right hand is nook closing member fixedly, and left hand is held the sleeve pipe handle and along arc plastic bushing sent into vein, behind the plastic bushing intravasation, recover its straight shape, keep somewhere and the fixed plastics sleeve pipe, sleeve pipe handle tail end nipple joint connects syringe or transfusion device, finishes venipuncture procedure.Because the arc and the vein arc of puncture needle needle point place section are consistent, and, farthest avoided wearing out the incidence rate that the vein rear wall causes complication such as hematoma, subcutaneous extvavasated blood owing to taked to choose the method puncture of puncture needle.
