Problems solved by technology

Since the puncture angle and the length of the puncture needle need to be mastered manually under the guidance of B-ultrasound, it can only be used to puncture actual sexual organs and large lesions, and cannot achieve superficial venipuncture

Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings and specific examples.

[0020] As shown in FIGS. 1 and 2 , this example includes a B ultrahigh frequency linear array probe 2 with a wire 3 . A fixing frame 1 is fixed at the bottom of the B ultrahigh frequency linear array probe 2 , and the bottom surface of the fixing frame 1 is on the same plane as the bottom surface of the B ultrahigh frequency linear array probe 2 . An oblique puncture frame 5 is fixed on one side of the fixed frame 1 , and the overall direction axis 15 of the puncture frame 5 forms an included angle of 30° with the bottom surface of the B ultrahigh frequency linear array probe 2 . The setting of the puncture frame 5 requires ensuring that the overall direction axis 15 of the puncture frame 5 intersects with the vertical line downward from the center point of the B ultrahigh frequency line array probe 2 (this line is perpendicular to the bottom surf...

Abstract

The utility model relates to a superficial venipuncture spear guided by type-B ultrasonic and a calculation method of the needle insertion length, which comprises a type-B ultrasonic high frequency linear-array probe (2), the overall trend axes (15) of a puncture frame (5) is at an angle of 30 degrees to the bottom surface of the type-B ultrasonic high frequency linear-array probe (2); a puncture bolt (10) is slide-arranged on the puncture frame (5), a puncture needle (11) is fixedly connected with the puncture bolt (10), the needle shank trend of the puncture needle (11) is parallel to the overall trend axes (15) of the puncture frame (5); the front-end of the puncture frame (5) is slide-connected with a locating bolt (4); the front-end of the puncture frame (5) is also provided with a size scale mark (12). The utility model realizes an accurate superficial venipuncture guided by type-B ultrasonic, has a convenient and quick operation, and avoids the pain of patients caused by repeating punctures for seeking the blood vessel.

Description

technical field [0001] The invention relates to a puncture device, in particular to a superficial vein puncture device. It also relates to a method for calculating the needle insertion length of the superficial venipuncture device. Background technique [0002] Superficial venipuncture is a frequent medical method, and the current practice is to insert the needle manually based on perception and experience. On the one hand, it is troublesome to find veins, and it is difficult to accurately grasp the needle insertion angle and length, especially for some patients with fat body, thin blood vessels, and vasoconstriction; to greater pain. [0003] At present, there are many B-ultrasound-guided positioning puncture devices on the market. Its general structure is that the fixed frame is fixed on the B-ultrasound probe, and the puncture device is installed on the fixed frame. Since the puncture angle and the length of the puncture needle need to be mastered manually under the g...
