Embodiment 2

[0054] Figure 10 It shows a structural cross-sectional view of a split-type disposable array injection needle according to an embodiment of the present invention, which includes a needle seat 6, which is a hollow structure with two ports, and the distance between the normal lines of the two ports is Parallel or perpendicular to each other or form other set angles, the inlet port of the two ports is used to connect the nozzle of the syringe or the interface of the infusion tube, and the outlet port uses structural glue 7 to seal and fix the metal needle tube array element at the port. The positioning part 2 and the needle holder 6 in the metal needle tube array element are made in a separate form.

[0055] The disposable array injection needle of this embodiment also includes a needle tube protective cover (not shown in the figure), which is a hollow tube with a single end opening, and the open end of the hollow tube is covered on the needle holder 6 to protect the metal needl...

Embodiment 3

[0063] Figure 15 A cross-sectional view of the structure of a disposable array injection needle that can be used in conjunction with an insulin injection pen according to an embodiment of the present invention is shown, which includes a needle hub 6 , a needle tube protective sheath 12 and a needle hub protective sheath 13 . The needle base 6 is a cylindrical tube with an open bottom, a top cover and a second positioning through hole 9 on it, the bottom end of which is used to connect with the injection fluid reservoir; the metal needle tube array element is sealed and fixed above the top cover , and a chamber 10 is formed between the top cover; a liquid-taking needle 11 is inserted into the second positioning through hole 9, and one end of the liquid-taking needle 11 communicates with the chamber 10, and the other end is a needle located in the columnar tube, The needle is used to extract the infusion solution from the infusion solution reservoir to the chamber 10 .

Abstract

The invention discloses a metal needle tube array component which comprises a metal needle tube array, a structural adhesive substrate and a locating piece. The metal needle tube array comprises at least two metal tubes. The two metal tubes are used for transmitting liquid, are arrayed at a preset interval and are fixed on the structural adhesive substrate. One end of each metal tube is used as a needle tip for puncture, and the other end of each metal tube penetrates through the structural adhesive substrate and is inserted in a locating through hole of the locating piece connected with the structural adhesive substrate. The metal needle tubes and the locating piece are sealed and combined into a whole in an adhesive mode by the structural adhesive substrate so that liquid can only pass through the inside of the metal needle tubes. The invention further discloses an injection needle head based on the metal needle tube array component. Lot manufacturing, with low cost and a high finished product rate, of the he metal needle tube array component and the injection needle head can be realized by utilization of existing mature processing technology and specified conventional medical materials. Blanks in relevant application fields are expected to be filled. Consequently, enormous economic benefit and social benefit can be created, and contribution is conducted to health and beautiful life of human beings.

Description

technical field [0001] The invention relates to the technical fields of medical equipment, beauty equipment and medicine, in particular to a metal needle tube array element and its injection needle. Background technique [0002] Injection technology and injection devices play an important role in medical cosmetology and treatment of diseases such as diabetes. In recent years, cosmetic and plastic surgery has become more and more popular around the world. Disposable syringes have been widely used for injection of fillers on the forehead, corners of the eyes, between the eyebrows, nasolabial folds, corners of the mouth, neck and other parts of the face and other parts of the body. In plastic surgery, it is usually necessary to inject uniformly at a certain depth in an area, but the existing injection needles only have a single needle tube, so only repeated injections can only be performed at this time, the treatment time is long, the patient suffers a lot, and it is difficult ...
