Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary device technology, and in particular to a medical hand restraint device to prevent unplanned extubation of patients. Background Technology

[0002] In the medical setting, hospitalized patients (especially post-surgical patients) have various tubes inserted, including gastric tubes, urinary catheters, wound drainage tubes, and central venous catheters (CVCs). During the day, patients are conscious and can control their hand movements, avoiding touching the tubes. However, at night, during deep sleep, patients may experience itching or a foreign body sensation at the tube insertion sites, leading them to unconsciously pull out the tubes. When medical staff inquire about tube removal during morning rounds, patients often claim ignorance. Investigations reveal that over 70% of unplanned tube removals occur during deep sleep. To reduce the rate of unplanned tube removal in hospitals, appropriate hand restraint is necessary. Existing restraint methods, such as restraint straps and restraint garments, suffer from low comfort, potential skin damage, and excessive restriction of patient movement. They may also trigger psychological resistance and anxiety, even worsening the condition. In clinical practice, restraining hand movements is essential for patients who are agitated, confused, mentally ill, or experiencing post-operative delirium to prevent them from removing catheters, scratching wounds, or self-harm. Early restraint devices can be traced back to rigid restraints of the 19th century. Improvements in materials during the 20th century primarily employed rigid restraint tools made of leather, canvas, or metal, such as handcuffs or straps. These devices physically restrict patient movement, but they have the following significant drawbacks: 1. Low comfort: Traditional restraint tools, often made of rigid materials, can easily cause pressure sores and poor blood circulation with prolonged use. 2. Excessive restriction of movement: Completely restricting joint movement can easily lead to muscle atrophy or joint stiffness, increasing patient discomfort and psychological stress. 3. Lack of humanistic care: Traditional restraint methods neglect the psychological needs of conscious patients, easily causing negative emotions such as fear, anxiety, and resistance. The appearance of the devices can also evoke a sense of "punishment," exacerbating anxiety and resistance, which is detrimental to treatment and rehabilitation. 4. Inconvenient operation: Some traditional restraint tools are cumbersome to wear and require multiple people to operate, increasing the workload of medical staff. Furthermore, the existing restraints do not restrain the fingers. Even after restraint, the patient's fingers can still move, and they can still use their hands to untie the straps and break free of the restraints, which could lead to the removal of the tubes from their body.

[0003] In line with current changes in medical philosophy, market demands are increasing for more humane care, minimizing restraint, quick fixation, comfort, and pressure ulcer prevention designs. This reflects a shift in medical technology from "forceful control" to "humanized care," aiming to provide patients with a safer, more comfortable, and humane restraint method. Industry standards and regulations are driving this shift. International medical device regulatory agencies (such as the FDA and CE) have imposed stringent requirements on the biosafety, mechanical performance, and ethical compliance of restraint devices, further driving technological innovation. For example, the ISO 13485 standard requires restraint devices to be reusable and durable; self-injury prevention certification requires passing tests such as tear resistance and bite resistance to ensure that patients cannot free themselves.

[0004] Utility model patent with patent number 202120568110.3 discloses a medical hand restraint device. Its technical features include a hemispherical support, an upper restraint band, a lower restraint band, a fixing band, an adjusting band, and a rotation limiting component. The rotation limiting component is sleeved on the outside of the lower and upper restraint bands. The adjusting band is fixedly connected to the rotation limiting component. The edges of the upper and lower restraint bands are connected. Zippers are provided on the hand portions of the upper and lower restraint bands. Openings are formed at the wrist portions of the upper and lower restraint bands. Loops are detachably provided on the outside of the wrist portions of the upper and lower restraint bands. The inner hand portion of the upper restraint band is fixedly connected to the hemispherical support. A plastic plate is fixedly installed within the interlayer of the lower restraint band. After wearing the device, the hand is fully extended, with the palm pressed against a hard lower plate. The fingers cannot bend towards the palm. For patients requiring prolonged immobilization and unable to move their hands, this can easily cause frustration and affect the movement of the hand limbs, leading to joint stiffness and muscle atrophy in the hand.

[0005] Utility model patent with patent number 201922264713.X discloses a medical hand restraint device. Its technical features include: a connecting bag, a grip strengthener, a wrist fixation strap, and at least one restraint strap; the connecting bag is horizontally positioned; the grip strengthener is located at the front end of the connecting bag and below it, comprising a grip ring and five finger rings located outside the grip ring, each finger ring being integrally connected to the grip ring, and the grip ring and finger rings being made of rubber; the middle part of the wrist fixation strap is located at the rear end of the connecting bag, and the two ends of the wrist fixation strap are connected by an adjustable fastening structure; the upper surface of the wrist fixation strap has multiple positioning rings arranged sequentially along its length, and the restraint strap passes through each positioning ring sequentially.
