Abstract
Provided is a method for locating a human target using superficial vein characteristics, which includes acquiring a model displaying both of the human target and superficial veins; projecting the model on a body surface where the superficial veins are located, so that a ratio of a projection on the body surface to actual dimensions of a human body is (0.9-1.1):1; and adjusting a position of the projection of the model, observing the superficial veins, and making at least two of the superficial veins coincide with veins in the projection of the model, and determining that a position of the human target in the projection of the model is a projection of the human target on the actual body surface.
Claims20
A method for locating a human target using superficial vein characteristics, comprising:
- acquiring a model displaying both of the human target and superficial veins;
- projecting the model on a body surface where the superficial veins are located, so that a ratio of a projection on the body surface to actual dimensions of a human body is (0.9-1.1):
- 1;
- or printing, by using a transparent material, the model according to a size ratio, (0.9-1.1):
- 1, of the model to a human body so as to form a superficial vein mold;
- and
- adjusting a position of the projection of the model, observing the superficial veins, and making at least two of the superficial veins coincide with veins in the projection of the model, and determining that a position of the human target in the projection of the model is a projection of the human target on the actual body surface;
- or placing the superficial vein mold on the body surface, adjusting a position of the superficial vein mold, observing the superficial veins, and making at least two of the superficial veins coincide with veins in the superficial vein mold, and determining that a position of the human target on the superficial vein mold is a projection of the human target on the actual body surface.
A device for locating a human target using superficial vein characteristics, comprising:
- a vein display device, a brace and a human target matching device, wherein
- the brace comprises a ring-shaped bracket and a plurality of legs connected to the ring-shaped bracket;
- the vein display device is disposed on the ring-shaped bracket;
- and the human target matching device is a superficial vein mold or a projector, wherein the superficial vein mold comprises a transparent material on which a vein map and a human target hole are disposed, in a case where the human target matching device is the projector, the projector is connected to the vein display device;
- and
- the ring-shaped bracket is provided with at least one support ring for supporting the vein display device;
- and a number of the plurality of legs is at least three, and each of the legs comprises a slip ring and a support rod connected to the slip ring, wherein the slip ring is sleeved on the vein display device.
