Description

Shoulder pad for brachial plexus block

Technical Field

The application relates to the technical field of brachial plexus block, in particular to a shoulder pad for brachial plexus block.

Background

Brachial plexus block anesthesia is an anesthesia method for injecting local anesthetic around brachial plexus nerve trunk to generate nerve conduction block in the area dominated by the brachial plexus nerve trunk, and is suitable for various operations of hands, forearms, upper arms and shoulders. Among them, the intermuscular groove approach and the axillary approach are the most commonly used approaches at present.

The injection part of the intertuscular groove access is positioned at the level of the patient's neck cricoid cartilage and the intersection point of the anterior oblique muscle and the central oblique muscle, and during clinical treatment, the patient is usually required to lift one side of the shoulder upwards and keep the posture unchanged so as to facilitate the injection of anesthetic by a clinician; the injection part of the axillary route is positioned in the axillary fossa of a patient, and usually shoulder joints of the patient are required to be abducted and lifted, elbow joints are required to be bent, the back of the hand is pasted on a bed, and a 'military ceremony' posture is put out to better expose the local part of the axillary fossa.

With respect to the related art in the above, the inventors consider that the following problems exist: the patient need remove the limb that suffers from at the in-process that the position was put, leads to suffering from the pain aggravation of limb to lead to patient's degree of cooperation relatively poor, be unfavorable for the exposure of puncture position, thereby influence anesthesia effect.
