[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 fixing device for limiting accidental extubation of an intensive care unit (ICU) patient. The hand fixing device comprises a hand back fixing part, spring pre-tighteningparts and finger fixing parts. When the fingers of a patient do a grasp, Bowden cables are pulled, and since each Bowden cable is fixed onto a corresponding pre-tightening bolt, the pre-tightening bolt and a corresponding pre-tightening nut can move in a spring sleeve simultaneously; since each pre-tightening spring is in contact with one side of the corresponding pre-tightening nut, the pre-tightening spring can be compressed when the corresponding pre-tightening nut moves; each pre-tightening spring can generate elastic force to hinder movement of the corresponding pre-tightening nut; and the magnitude of force generated by each pre-tightening spring increases along with movement of the corresponding pre-tightening nut until grasp force of the patient is not greater than resistance generated by the pre-tightening spring, thereby effectively limiting the extubation of the patient.
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...
