Description
TECHNICAL FIELD
[0001] The utility model belongs to the technical field of medical auxiliary instrument, more specifically, relate to a radial artery puncture fixed bracket. BACKGROUND
[0002] Radial artery is an important peripheral artery of human body, which is located on the radial side of forearm (close to the thumb side). Radial artery originates from the bifurcation of brachial artery, runs down along the forearm, and finally forms radial artery pulsation near the wrist, which is also the place we usually use to measure pulse.
[0003] Radial artery puncture is a common medical operation, which is usually used to obtain arterial blood sample for blood gas analysis or for arterial catheterization. When performing radial artery puncture, the patient is usually required to stretch the arm and tilt the palm upward to make the radial artery in the upper position. The medical staff finds the pulsation point of the radial artery by touching the position near the thumb side of the wrist, fixes the patient's wrist with one hand, and then inserts the needle into the skin at an appropriate angle until it enters the radial artery. After confirming the correct position of the needle, the required amount of arterial blood is drawn, and finally the needle is pulled out.
[0004] When performing radial artery puncture, the medical staff needs to fix the patient's wrist with one hand to keep the radial artery on the wrist straight, and operate with the other hand, which not only has high difficulty, but also may cause the needle to move if the patient's wrist moves accidentally, which requires re-puncture and increases the patient's pain. UTILITY MODEL CONTENTS
[0005] The utility model aims at providing a radial artery puncture fixed bracket, which aims to solve the problem of high difficulty of single-handed operation of medical staff and easy movement of patient's wrist to cause the needle to move during radial artery puncture.
[0006] To achieve the above-mentioned purpose, the utility model adopts the technical scheme of providing a radial artery puncture fixed bracket, which comprises:
[0007] A bracket main body, the bracket main body comprises a bottom supporting plate and a side baffle, the side baffle is vertically arranged on the outer side of the upper end surface of the bottom supporting plate, and an arc-shaped supporting surface for tilting and supporting the forearm is formed between the bottom supporting plate and the side baffle;
[0008] A fixing bandage, the fixing bandage comprises a front side bandage and a rear side bandage, the front side bandage is arranged on the front side of the bracket main body for fixing the palm of the patient, and the rear side bandage is arranged on the rear side of the bracket main body for fixing the forearm of the patient;
[0009] Supporting pads are arranged on the arc-shaped supporting surface, and the supporting pads are located between the front side strap and the rear side strap for oblique supporting of the wrist of the patient.
[0010] In a possible implementation, the bottom supporting plate and the side plate are integrally formed.
[0011] In a possible implementation, the surface of the arc-shaped supporting surface is provided with an elastic layer.
[0012] In a possible implementation, the length of the bracket body is 25-40 cm.
[0013] In a possible implementation, the supporting pad is a silica gel soft pad or an air bag.
[0014] In a possible implementation, the upper end surface of the supporting pad is provided with an oblique supporting surface for oblique supporting of the wrist of the patient, and the two sides of the oblique supporting surface are provided with arc-shaped transition surfaces.
[0015] In a possible implementation, the angle between the oblique supporting surface and the horizontal plane is 30-60°.
[0016] In a possible implementation, the front side strap and the rear side strap are both elastic straps.
[0017] The radial artery puncture fixing bracket has the advantages that before radial artery puncture is performed, the patient first tilts the forearm upward and overlaps the forearm on the arc-shaped supporting surface between the bottom supporting plate and the side plate, at this time, the wrist of the patient overlaps the supporting pad, so that the wrist of the patient is supported upward to keep the radial artery on the wrist in a straightened state, the front side strap is used to fix the palm of the patient, the rear side strap is used to fix the forearm of the patient, and finally the forearm of the patient is fixed on the bracket body. The radial artery puncture fixing bracket can fix the forearm of the patient in a state that the wrist is supported upward, ensure that the radial artery on the wrist is always in a straightened state, and the medical staff can perform radial artery puncture with both hands without fixing the arm of the patient with one hand, so that the radial artery puncture is convenient and the occurrence of "needle running" is reduced.
