[0002] Accidental extubation in ICU refers to self-extubation without the consent of medical staff and failure to meet the gatekeeping characteristics. At present, the main reasons for accidental extubation in ICU patients are: (1) ICU patients will appear restless and unconscious after waking up , delirium state, leading to self-extubation
(2) Conscious and irritable patients lack effective restraint and continuous sedation, and the existence of foreign objects such as tracheal intubation and gastric tube intubation stimulates and oppresses the nasal cavity and oral mucosa, causing pain, which leads to self-extubation
(3) The unfamiliar environment of the ICU makes the patient fearful, and the alarm sound of the instrument brings psychological hints and psychological pressure to the patient, causing the patient to extubate himself
In this patent, the movement of the fingers is not restrained, and limited movement within the specified range of motion cannot be achieved

Embodiment
[0028] figure 1 It is a structural diagram of a specific embodiment of a hand immobilization device for limiting accidental extubation of ICU patients according to the present invention.
[0029] In this example, if figure 1 As shown, a hand immobilization device of the present invention that restricts accidental extubation of ICU patients includes: 1-back of hand immobilization part, 2-spring pretensioning part and 3-finger immobilization part;
[0030] Among them, such as figure 2 As shown, 1-hand back fixing part includes 1.1-bandage, 1.2-fixing plate and 1.3-dovetail wedge;
[0031] 1.2-The fixed plate is bound on the back of the human hand through the 1.1-strap, and the 1.1-strap can be adjusted according to the patient’s needs; 2-The spring pre-tensioning mechanism is stuck on the 1.2-fixed plate through the 1.3-dovetail wedge, and then through 1.2 - the threaded holes on the fixing plate are fixed on the 1.2-fixing plate;
[0032] Such as image 3 As shown, 2-spri...

The invention discloses a hand immobilization device for limiting accidental extubation of ICU patients, which includes a dorsal immobilization part, a spring pretensioning part and a finger immobilization part; It is fixed on the pre-tightening bolt, so the pre-tightening bolt and the pre-tightening nut will move in the spring sleeve at the same time; since the pre-tightening spring is in contact with one side of the pre-tightening nut, the pre-tightening spring will be compressed when the pre-tightening nut moves, and the pre-tightening nut The tightening spring will generate elastic force to hinder the movement of the pre-tightening nut, and the magnitude of the force generated by the pre-tightening spring will increase with the movement of the pre-tightening nut until the patient's grasping force is not greater than the resistance generated by the pre-tightening spring, thereby effectively limiting the patient's ability to extubation action.
Description
technical field [0001] The invention belongs to the technical field of medical devices, and more specifically relates to a hand immobilization device for limiting accidental extubation of ICU patients. Background technique [0002] Accidental extubation in ICU refers to self-extubation without the consent of medical staff and failure to meet the gatekeeping characteristics. At present, the main reasons for accidental extubation in ICU patients are: (1) ICU patients will appear restless and unconscious after waking up , Delirium state, leading to self-extubation of the patient. (2) Awake and irritable patients lack effective restraint and continuous sedation, and the existence of foreign objects such as tracheal intubation and gastric tube intubation stimulates and compresses the nasal cavity and oral mucosa, causing pain, which leads to self-extubation. (3) The unfamiliar environment of the ICU makes the patient fearful, and the alarm sound of the instrument brings psycholo...
