A drug delivery puncture needle

Abstract

A drug delivery puncture needle comprises a puncture needle tube, wherein one side of the outer surface of the puncture needle tube is provided with a plurality of first reflective surfaces distributed at equal intervals along the length direction, and a second reflective surface facing the other side is provided near the head end of the puncture needle tube. After the puncture needle tube is inserted, the first reflective surface on the puncture needle tube can be observed with the help of an ultrasonic imaging system to confirm the scope of the inserted area. When the designated area is about to be reached, the puncture needle tube is rotated, and at this time, the ultrasonic imaging system receives the second reflective surface, and can accurately capture the position of the needle tip, so that the needle tip can be accurately inserted into the drug delivery area to achieve accurate drug delivery.

[0029] The specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that those skilled in the art can more clearly understand how to practice the present invention. Although the present invention is described in conjunction with its preferred specific embodiments, these embodiments are only illustrative, rather than limiting the scope of the present invention.

[0030] Example 1

[0031] See also Figure 1 and Figure 2 A drug administration puncture needle comprises a puncture needle tube 1, on the outer surface of which a plurality of first reflection surfaces 101 are evenly spaced along the length direction of the puncture needle tube 1, and on the outer surface of the puncture needle tube 1 a second reflection surface 102 is provided near the head end.

[0032] The first reflecting surface 101 and the second reflecting surface 102 are respectively arranged on both sides of the puncture needle tube 1. The first reflecting surface 101 and the second reflecting surface 102 are both composed of two concave planes arranged along the length direction of the puncture needle tube 1 and arranged at an angle.

[0033] Example 2

[0034] See also Figure 3 and Figure 4 A drug administration puncture needle comprises a puncture needle tube 1, on the outer surface of which a plurality of first reflection surfaces 101 are evenly spaced and distributed along the length direction of the puncture needle tube 1 are provided, a notch 102 is provided on the side of the head of the puncture needle tube 1, and a second reflection surface 103 is provided at the head of the inner surface of the puncture needle tube 1 corresponding to the notch 102.

[0035] The first reflecting surface 101 and the notch 102 are respectively arranged on both sides of the puncture needle tube 1. The first reflecting surface 101 is composed of two concave planes arranged along the length direction of the puncture needle tube 1 and arranged at an angle. The head end of the second reflecting surface 103 is connected to the inner surface of the puncture needle tube 1, and the tail end of the second reflecting surface 103 is inclined toward the side where the first reflecting surface 101 on the puncture needle tube 1 is located, and extends backward to the head of the notch 102.

[0036] Example 3

[0037] See also Figures 5 to 7A drug administration puncture needle comprises a puncture needle tube 1, on the outer surface of which a plurality of first reflection surfaces 101 are evenly spaced and distributed along the length direction of the puncture needle tube 1, a notch 102 is provided on the side of the head of the puncture needle tube 1, and a reflection arm 103 having a second reflection surface is connected to the head end of the notch 102.

[0038] The first reflecting surface 101 and the notch 102 are respectively arranged on both sides of the puncture needle tube 1. The first reflecting surface 101 is composed of two concave planes arranged along the length direction of the puncture needle tube 1 and arranged at an angle. The head end of the reflecting arm 103 is connected to the head end of the notch 102, and the tail end of the reflecting arm 103 is inclined toward the side where the first reflecting surface 101 on the puncture needle tube 1 is located.

[0039] Example 4

[0040] See also Figure 8 and Fig. 9 A drug administration puncture needle comprises a puncture needle tube 1 and an insert 2, wherein the outer surface of the puncture needle tube 1 is provided with a plurality of first reflection surfaces 101 equally spaced along the length direction of the puncture needle tube 1, and the inner side of the head end of the puncture needle tube 1 is inlaid with an insert 2 having a second reflection surface 201.

[0041] The first reflecting surface 101 is disposed on one side of the puncture needle tube 1 , and the second reflecting surface 201 of the insert 2 faces the other side of the puncture needle tube 1 .

[0042] The operating principles of all the above embodiments are as follows: after the puncture needle tube 1 is inserted, the ultrasonic imaging system is used to observe the multiple first reflective surfaces on the outer surface of the puncture needle tube 1 to confirm the area where the puncture needle tube 1 is inserted. When it is about to reach the designated area, the puncture needle tube 1 is rotated. At this time, the ultrasonic imaging system receives the second reflective surface close to the needle tip at the head end, and can accurately capture the position of the needle tip, so that it can accurately pierce the drug delivery area and achieve precise drug delivery.

[0043] In addition, the second reflecting surface can not only be composed of two concave planes arranged at an angle as shown in the above embodiment, which has the advantage of simple processing, greatly reduces the difficulty of operation, and solves the problem of misoperation caused by unclear reflecting surface, but also can adopt a concave spherical structure, which can concentrate on enhancing the signal and has a stronger signal performance.

The above embodiments are merely illustrative of the invention, not limiting thereof. In short, the scope of protection of the invention should include those variations or substitutions and modifications that are obvious to a person of ordinary skill in the art.
