Description

A fixation device for anesthesiology

technical field

The invention relates to the technical field of medical anesthesiology, in particular to a fixing device used in anesthesia.

Background technique

Anesthesia is generally believed to be a reversible functional inhibition of the central and peripheral nervous systems produced by drugs or other methods. This inhibition is mainly characterized by loss of sensation, especially pain, and is often used in various clinical operations. use.

General anesthesia referred to as general anesthesia: refers to the inhalation of anesthetics through the respiratory tract, intravenous or intramuscular injection into the body, resulting in temporary depression of the central nervous system, clinical manifestations of loss of consciousness, loss of general pain, amnesia, reflex inhibition and skeletal muscle relaxation; The degree of nervous system inhibition is related to the concentration of drugs in the blood, and can be controlled and regulated; this inhibition is completely reversible. When the drug is metabolized or excreted from the body, the patient's consciousness and various reflexes gradually recover, and the general anesthesia operation wakes up. After the patient is prone to restlessness, mainly manifested as excitement, involuntary limb movement, etc., resulting in increased heart rate and blood pressure, and the patient's unconscious movement and struggle can easily cause the catheter to fall off. When the restless patient feels the bronchial intubation When the catheters such as oxygen masks and oxygen masks are interfered, it is easy to subconsciously pull them by hand.

Therefore, medical staff need to take necessary measures to fix the patient. Most of the existing auxiliary fixation devices use straps to tie the patient's limbs to the bed. Some patients with severe restlessness will use straps to fix the trunk to the bed. body.

In the auxiliary fixing device of the prior art, the following situations generally cause great inconvenience to the medical staff: the fixation is not firm and the fixing effect is not good: when the medical staff fixes the restless patient on the bed, most The patient's limbs are tied tightly with cloth belts, elastic straps, etc. Due to the unsatisfactory fixation effect, the patient's restless struggle can easily break free from the restraint of the cloth belt, which will lead to accidents and cause secondary injuries to the patient.
