Armpit protection pad used after cardiac pacemaker implantation

Abstract

The armpit protection pad comprises a strap, a first supporting rod, a second supporting rod and a protection pad assembly, the strap is fixed to an arm, a mounting cavity is formed in the first supporting rod, one end of the first supporting rod is connected with the strap, a mounting hole is formed in the other end of the first supporting rod, one end of the second supporting rod is inserted into the mounting cavity, and the other end of the second supporting rod is connected with the protection pad assembly. A spring is arranged between the second supporting rod and the installation cavity. When in use, the strap is fixed on the upper arm of a patient, the protection pad is positioned in the armpit, and the spring is compressed, so that when the position of the upper arm of the patient is changed, the protection pad cannot fall off from the armpit under the supporting action of the strap, the first supporting rod and the second supporting rod, and even if the upper arm of the patient slightly extends outwards, the protection pad cannot fall off from the armpit under the jacking action of the spring. The protection pad can still be kept in the armpit and cannot fall off from the armpit, so that absorption of sweat in the armpit can be prevented from being affected, and the situation that the workload is increased due to the fact that medical workers place protection pads again for a patient frequently can be avoided.
