Material: PU Gel
Definition: It is a medical device which is used in an operating room to protect patient from pressure sores during surgery.
Model: Different positioners are used for different surgical positions
Color: Yellow, blue, green. Other colors and sizes can be customized
Product characteristics: Gel is a kind of high molecular material, with good softness, support, shock absorption and compression resistance, good compatibility with human tissues, X-ray transmission, insulation, non-conductive, easy to clean, convenient to disinfect, and does not support bacterial growth.
Function: Avoid pressure ulcer caused by long operation time

Product characteristics
1. The insulation is non-conductive, easy to clean and disinfect. It does not support bacterial growth and has good temperature resistance. The resistance temperature ranges from -10 ℃ to +50 ℃
2. It provides patients with good, comfortable and stable body position fixation. It maximizes the exposure of the surgical field, reduce the operation time, maximize the dispersion of pressure, and reduce the occurrence of pressure ulcer and nerve damage.

Cautions
1. Do not wash the product. If the surface is dirty, wipe the surface with a wet towel. It can also be cleaned with neutral cleaning spray for better effect.
2. After using the product, please clean the surface of the positioners on time to remove dirt, sweat, urine, etc. The fabric can be stored in a dry place after drying in a cool place. After storage, do not put heavy objects on top of the product.

Ulnar brachial nerve protector
What is ulnar nerve?
The ulnar nerve is a terminal branch of the medial cord of the brachial plexus. It contains mainly fibers from the anterior rami of spinal nerves C8 and T1, but may sometimes carry C7 fibers as well.

From its origin, the ulnar nerve courses distally through the axilla, arm and forearm into the hand. It is a mixed nerve and provides motor innervation to various muscles of the forearm and hand as well as sensory supply to the skin of the hand.

The ulnar nerve can broadly be described as the nerve of the hand, as it innervates the vast majority of the intrinsic hand muscles. It is one of the most clinically relevant nerves of the upper limb, due to its superficial course and clinically apparent role in hand function.

Arm
From the medial cord, the ulnar nerve passes distally through the axilla, medial to the axillary artery. It descends on the medial aspect of the arm, medial to the brachial artery and the biceps brachii muscle. In the mid-portion of the arm, the nerve pierces the medial intermuscular septum to enter the posterior compartment. Here, the nerve runs anterior to the medial head of triceps barchii muscle and in 70-80% of people, this nerve passes under the arcade of Struthers. This is a thin, aponeurotic band, that extends from the medial head of triceps to the medial intermuscular septum.

The ulnar nerve then passes between the medial epicondyle and olecranon in the groove for ulnar nerve to enter the anterior compartment of the forearm. Posterior to the medial epicondyle, the ulnar nerve is subcutaneous and easily palpable. It is commonly referred to as the “funny bone” in this region. The ulna nerve typically has no branches in the arm.
