[0029] The camera 32 is used to image a venous blood vessel of a human body part to obtain an image of a venous blood vessel. In this embodiment, the lens (not shown) of the camera 32 is an infrared coated lens. It should be noted that the camera 32 may be fixed to a specific position of the slide rail 31, or may be configured as a movable structure, that is, the camera 32 may be moved on the slide rail 31 to adjust the camera. 32 location [0030] The laser irradiation unit 33 includes a motor 330, a pulley 331, a fixed shaft 332, a laser generator 333, and a laser filter 334. The pulley 331 is disposed on the slide rail 31. The motor 330 is disposed at a position below the pulley 33 1 . The fixed shaft 332 is disposed at a lower position of the motor 330, the laser generator 333 is disposed at a bottom of the fixed shaft 332, and the laser filter 334 is disposed at the laser generator 33.

When the first rotating shaft 361 and the second rotating shaft 362 are rotated, the roll is rotated, and the position of the light-transmitting hole 360 is changed. In the present embodiment, the roll 363 is a black opaque roll. The controller 37 is electrically connected to the first rotating shaft 361 and the second rotating shaft 362 for controlling the rotation of the first rotating shaft 361 and the second rotating shaft 362 to drive the roll 363 to move, thereby changing The position of the light transmission hole 360.

[0038] When the position of the light transmission hole 360 on the cylinder cover 36 is changed, the laser irradiation portion 33 moves along the slide rail 31 so that the infrared laser light generated by the laser generator 333 is always irradiated to the light transmission. Hole 360.

By attaching the canopy 36 to the body part, it is possible to avoid more or less scattering of the infrared laser, and it is possible to more accurately image the vein of the human body.

[0040] The camera 32, the laser irradiation portion 33, the telescopic cylinder 35, and the cylinder cover 36 are all electrically connected to the controller 37.

The controller 37 is for controlling the camera 32, the laser irradiation portion 33, the telescopic cylinder 35, and the cylinder cover 36.

[0041] Specifically, the controller 37 controls the telescopic cylinder 35 to expand and contract, and attaches the cylinder cover 36 to the human body part. The controller 37 controls the canister 36 and adjusts the position of the light-transmissive aperture 360 on the canister 36. The controller 37 controls the laser irradiation portion 33 to generate infrared laser light, controls the laser irradiation portion 33 to move along the slide rail 30, and irradiates the infrared laser light to the human body portion through the light transmission hole 360. The controller 37 controls the camera 333 to image a vein of a human body portion irradiated with infrared laser to obtain an image of a vein.

[0042] The working principle of the venous blood vessel imaging device 3 for improving imaging sharpness is as follows: The venous blood vessel imaging device 3 is placed on a human body part, and the controller 37 controls the venous blood vessel imaging device 3 to start. The telescopic cylinder 35 is elongated and the cylinder cover 36 is attached to the human body part. The laser generator 333 generates infrared laser light and is irradiated to the human body part through the light transmission hole 360. The camera 32 is transparent to the human body. The venous blood vessel of the human body part in the hole 3 60 is imaged to obtain an image of the venous blood vessel to which the canopy 36 is attached to the position of the human body part.
