Embodiment Construction

[0029] Below in conjunction with specific embodiments, the present invention is further described, such as Figures 1 to 7 As shown, a precise positioning device for radial artery includes a base 1, the upper end surface of the base 1 is an arc surface, an arc-shaped chute 101 is opened in the longitudinal direction of the base 1, and the arc-shaped fixed support part includes a strap and a lateral arrangement The arc-shaped plate 2 is provided below the arc-shaped plate 2 with a connecting rod 3 slidably connected to the arc-shaped chute 101 , and a fine-tuning mechanism is disposed on one side of the arc-shaped plate 2 . The strap includes an arm strap 12 and a wrist strap 13. The arm strap 12 and the wrist strap 13 are respectively arranged on both sides of the arc plate 2, and the connection point between the wrist strap 13 and the arc plate 2 is lower than the arm strap. 12 The connection point with the arc plate 2.

Abstract

The accurate positioning device comprises a base, the upper end face of the base is an arc-shaped face, an arc-shaped sliding groove is formed in the base in the longitudinal direction, an arc-shaped fixing and supporting part comprises a bandage and a transversely-arranged arc-shaped plate, a connecting rod connected into the arc-shaped sliding groove in a sliding mode is arranged below the arc-shaped plate, and a fine adjustment mechanism is arranged on one side of the arc-shaped plate; the fine adjustment mechanism comprises a control rod, a handle and a positioning wedge block, the control rod is connected with the handle, and the connecting rod is connected with the control rod; auxiliary positioning mechanisms are connected to the two sides of the base in the longitudinal direction in a sliding mode and used for indicating the vertical intersection point position of the longitudinal direction of the scratchbone styloid process and the transverse direction of the index finger. The handle of the fine adjustment mechanism drives the operation rod and the arc-shaped plate to rotate, bending of wrist blood vessels is reduced, the vertical intersection point position of the longitudinal direction of the scratchbone styloid process and the transverse direction of the index finger is found through the auxiliary positioning mechanism, rapid positioning of the scratchbone artery and puncture operation are achieved, and the puncture efficiency of the radial artery of a patient is improved.

Description

technical field [0001] The invention relates to the technical field of medical auxiliary appliances, in particular to a precise positioning device for radial artery. Background technique [0002] The radial artery is located between the brachioradialis tendon and the flexor carpi radialis tendon. There is a 2cm palpable pulse from the wrist to the distal end of the radius. Radial artery puncture is widely used in the anesthesiology department to monitor real-time arterial blood pressure in surgical patients. The radial artery puncture of the method relies on hyperextension of the wrist. During the puncture, the patient is in a supine position, the upper limbs remain in the natural position, the palms are kept upward, and the wrist is fully exposed. The part is overextended by 30°. [0003] However, this method is a blind puncture method, which relies on the experience of medical staff to find the puncture position. The success rate depends on the clinical experience of medi...
