Abstract

The invention relates to a double tube intravenous injection needle and a use method thereof. The needle consists of a rubber section and a metal section, wherein the rubber section is composed of a rubber joint, a rubber plate and a rubber hose, the rubber joint and the rubber hose are hollow at the middle part, wherein one end of the rubber joint is connected with the rubber hose, the other end thereof is connected with a perfusion tube outside, and one end of the rubber plate is fastened to one side of the rubber joint; while the metal section is composed by connecting a metal plate and a metal needle, wherein the metal needle is of a hollow tubular structure and is sheathed outside the rubber hose, and the front end of the metal needle is pointed. The parts are connected, wherein the orifice of the rubber hose is arranged in the metal needle, and disinfection is carried out; the rubber joint is connected with an outside perfusion tube; the metal needle is pierced into the vein on the body surface while holding the rubber plate and the metal plate; the rubber hose is pushed into the vein deeply while pressing the metal plate and holding the rubber plate; the metal needle is pulled out skin with the rubber hose kept in the vein, while holding the rubber plate and the metal plate; and the rubber plate and the metal plate are fixed on skin by rubberized fabric. The invention is easy to operate and can be disposable after chemical or physical disinfection.

Description

Double tube intravenous injection needle and using method
Technical field
The present invention relates to a kind of double tube intravenous injection needle and using method.
Background technology
The metal intravenous infusion syringe that uses is not easy to fix at present, change with patient's limbs attitude easily to be shifted, thereby the piercing blood vessel wall causes edema, brings misery to patient.
Summary of the invention
The object of the present invention is to provide a kind of double tube intravenous injection needle and using method.
The double tube intravenous injection needle that the present invention proposes is made up of rubber part 1 and metal part 2.Wherein, rubber part 1 is made up of elastomer connector 3, rubber slab 4 and rubber hose 5, and elastomer connector 3 and rubber hose 5 are the middle part hollow-core construction, and elastomer connector 3 one ends connect rubber hose 5, the other end connects the external infusion pipe, and rubber slab 4 one ends are fixed in elastomer connector 3 one sides; Metal part 2 is connected to form by metallic plate 6 and metal needle 7, and metal needle 7 is a hollow tubular structures, and metal needle 7 is placed in outside the rubber hose 5, can move freely; Metal needle 7 front ends are sharp-pointed, are used to pierce through skin and superficial vein.
Among the present invention, rubber slab 4 and metallic plate 6 are used for skin surface is fixed in the present invention.
The using method of the double tube intravenous injection needle that the present invention proposes, concrete steps are as follows:
(1) said apparatus is connected, make the mouth of pipe of rubber hose 5 be positioned at metal needle 7, sterilization carries out disinfection;
(2) tube for transfusion of elastomer connector 3 with the outside is connected;
(3) hand-held rubber slab 4 and metallic plate 6 thrust the body surface vein with metal needle 7;
(4) pin metallic plate 6, hand-held rubber slab 4 pushes the vein depths with rubber hose 5;
(5) hand-held rubber slab 4 and metallic plate 6 withdraw from metal needle 2 from skin, only stay rubber hose 5 at intravenous;
(6) with medical proof fabric rubber slab 4 and metallic plate 6 are fixed on the skin.
Withdraw from skin after syringe needle outer layer metal syringe needle puncture of the present invention enters the body surface vein, the elastic hose of its internal layer is stayed in the vein blood vessel infused.Elastic hose can change in vein crooked with patient's posture, and the blunt mouth of pipe of its circle can piercing blood vessel, so can effectively reduce sense of discomfort and the danger that venous transfusion brings.
The present invention is easy and simple to handle to be easy to grasp, and need carry out disposable use behind chemistry or the physical disinfection.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 stretches into the generalized section of metal needle 7 for rubber hose 5 of the present invention.
The generalized section that Fig. 3 passes metal needle 7 for rubber hose 5 of the present invention.
Number in the figure: 1 is rubber part, and 2 is the metal part, and 3 are elastomer connector, and 4 is rubber slab, and 5 is rubber hose, and 6 is metallic plate, and 7 is metal needle.
The specific embodiment
Further specify the present invention in conjunction with the accompanying drawings below by embodiment.
Embodiment 1: following each parts are connected by Fig. 1-mode shown in Figure 3, and these those skilled in the art all can smooth implementation.
Elastomer connector 3 is a hollow tubular, is about 10mm, the about 5mm of external diameter, the about 4mm of internal diameter.Rubber slab 4 is the rectangle thin plate, is connected with elastomer connector 3, and thick about 0.5mm is about 10mm, wide about 5mm.Rubber hose 5 is a hollow tubular, with elastomer connector 3 be connected on one side, end circle is blunt, is about 20mm, the about 1mm of external diameter, the about 0.5mm of internal diameter.Metallic plate 6 is the rectangle thin plate, is connected with metal needle, and thick about 0.5mm is about 10mm, wide about 5mm.Metal needle 7 is a hollow tubular, is about 10mm, the about 1.5mm of external diameter, and the about 1mm of internal diameter is enclosed within rubber hose 5 outsides, can move freely on rubber hose 5, and one end circle is blunt, and an end is sharp keen, becomes 10-15 degree acute angle.
Using method is as follows:
(1) device provided by the invention is connected, makes the mouth of pipe (as shown in Figure 2) in metal needle 7 of rubber hose 5, be packaged into the sterilization paper bag after, sterilization carries out disinfection.
(2) use the front opening sterilization wrap, the tube for transfusion of elastomer connector 3 with the outside is connected, and define liquid and flow out from metal needle 2 front ends.
(3) sterilization skin surface, hand-held rubber slab 4 and metallic plate 6 thrust the body surface vein with metal needle 7.
(4) pin metallic plate 6, hand-held rubber slab 4 pushes vein depths (as shown in Figure 3) with rubber hose 5.
(5) hand-held rubber slab 4 and metallic plate 6 withdraw from metal needle 2 from skin, only stay rubber hose 5 at intravenous.With the special-purpose adhesive plaster of disinfectant rubber slab 4 and metallic plate 6 are fixed on the skin.
