[0002] Purposeless abnormal behaviors caused by disorientation or hallucinations in patients with impaired consciousness have become a key aspect of clinical nursing safety management. In states of illness such as delirium, hepatic encephalopathy, or hypoglycemic coma, patients often present with complex clinical manifestations due to acute cognitive impairment and loss of behavioral control: mild cases may present with restlessness and repeated attempts to get out of bed, while severe cases may have a sudden increase in the risk of falling from the bed due to spatial disorientation, or self-injurious scratching, ramming, or other behaviors induced by persecutory delusions, or even purposeless aggressive tendencies due to agitated psychotic symptoms.

[0003] Loss of control not only threatens the patient's safety but also increases the difficulty of nursing procedures, requiring comprehensive management through early identification of the primary disease characteristics, dynamic assessment of consciousness, and the appropriate use of protective restraints and pharmacological interventions. Currently, restraint garments are commonly used in clinical practice to immobilize the patient's upper body to prevent falls, self-harm, or harm to others; however, these restraint garments have problems, as covering the patient's upper body makes it difficult for medical staff to directly observe the patient's skin condition, wound condition, and whether intravenous lines under the garment are compressed, hindering timely detection of abnormalities; for larger patients, the restraint garment's straps may create a feeling of pressure, reducing patient comfort; existing techniques also use straps to restrain the patient's limbs individually, but the release is not convenient and cannot be quickly achieved in emergency situations.

[0004] Therefore, how to design a restraint strap quick-release structure that allows for intuitive observation of the patient's condition, timely detection of abnormalities, and improved patient comfort is a technical problem that has not yet been solved in the existing technology. Utility Model Content

[0032] The present application will now be described in detail with reference to the accompanying drawings and embodiments. Example

[0033] This embodiment provides a structure for the rapid deployment and retraction of a constraint strap, such as... Figure 1-4As shown, the device includes: a mounting plate 1, a connecting plate 13, connecting bolts 15, and a strap retractor 2; the mounting plate 1 is at least one, suitable for installation under at least one side of the hospital bed; the connecting plate 13 is at least two, respectively fixedly disposed on both sides above the mounting plate 1, and the connecting plate 13 has threaded through holes 14; the connecting bolts 15 are screwed into the threaded through holes 14 and then abut against the hospital bed, thereby installing the mounting plate 1 under the hospital bed; alternatively, mounting threaded holes corresponding to the threaded through holes 14 can also be opened on the hospital bed, and the connecting bolts 15 can pass through the threaded through holes 14 and continue to be screwed into the mounting threaded holes, thereby achieving a more stable installation; the strap retractor 2 is movably installed under the mounting plate 1, and includes a main body 3, a movable mounting structure, and a fixing plate. 4. A winding shaft 5, a limiting structure, an operating structure, and a pre-pressing structure; wherein, the main body 3 has an internal threaded through hole; a movable mounting structure is disposed above the main body 3 for movable mounting with the mounting plate 1; two fixing plates 4 are fixedly disposed below the main body 3 and are arranged opposite to each other; the winding shaft 5 is rotatably mounted on the two fixing plates 4 for winding the constraint band; the limiting structure is disposed outside one of the fixing plates 4 for limiting the rotation of the winding shaft 5; the operating structure is disposed outside the other fixing plate 4 for operating the rotation of the winding shaft 5; the pre-pressing structure is disposed on the main body 3 between the two fixing plates 4, located above the winding shaft 5, for pre-pressing the constraint band wound on the winding shaft 5.

[0034] Before using it on a patient with impaired consciousness, first place the mounting plate 1 under the bed, then rotate the connecting bolt 15 inward to press the mounting plate 1 onto the bed. Next, adjust the strap retractor 2 to the appropriate position according to the patient's height. After adjustment, use a dovetail bolt to screw into the internal threaded through hole, and rotate the dovetail bolt inward to abut against the bed, thereby limiting and fixing the strap retractor 2. Alternatively, a mounting threaded hole corresponding to the internal threaded through hole can also be made on the bed, and the dovetail bolt can pass through the internal threaded through hole and continue to be screwed into the mounting threaded hole, thereby achieving a more stable limiting and fixing. When used on a patient, the two ends of the restraint strap are wound onto the winding shaft 5. By rotating the winding shaft 5 clockwise using the operating mechanism, the restraint strap is gradually tightened to a suitable tightness, thus restraining the patient. Once the suitable tightness is reached, the rotation of the winding shaft 5 is stopped, and the limiting structure locks the winding shaft 5 to prevent rotation. During the winding process, the pre-pressure structure continuously applies pre-pressure to the restraint strap, ensuring that the restraint strap is evenly tightened on the winding shaft 5. The continuous pressure from the pre-pressure structure prevents the restraint strap from loosening from the winding shaft. In case of an emergency requiring rapid release of restraint, the restraint strap is released, and then quickly pulled along the extension direction of the restraint strap to allow it to be quickly removed from the bed, ensuring the patient can be evacuated quickly. Compared to traditional restraint garments, the quick-release structure of the restraint strap in this embodiment, used in conjunction with the restraint strap, ensures effective restraint of the patient while allowing medical staff to visually observe changes in the patient's vital signs to identify abnormalities. It also allows for precise control of the restraint tightness, avoiding discomfort caused by improper pressure. In addition, the restraint can be quickly released in case of an emergency, improving the safety and convenience of use.

[0035] like Figure 3 As shown, the movable mounting structure includes a slide rail 11 and a slide groove 12; wherein, the slide rail 11 is disposed below the mounting plate 1; the slide groove 12 is formed above the main body 3, the slide groove 12 is matched and installed with the slide rail 11, and can slide along the slide rail 11, thereby making the main body 3 and the mounting plate 1 movable.

[0036] The two fixed plates 4 are provided with rotating through holes 41 facing each other, and the winding shaft 5 is rotatably mounted on the two fixed plates 4 through the rotating through holes 41.

[0037] The winding shaft 5 has elongated openings 51 extending through both sides. The constraint strap is adapted to pass through the elongated openings 51 and can be wound around the winding shaft 5 when it rotates. After the constraint strap passes through the elongated openings 51, it is wound without needing to be fixed to the winding shaft 5. It can be automatically tightened when the winding shaft 5 is rotated.

[0038] like Figure 5-6As shown, the limiting structure includes a rotating ratchet 6, a pawl 62, a mounting base 63, a mounting groove 64, a first elastic element 65, and a limiting shaft 66; wherein, the rotating ratchet 6 is fixedly disposed at one end of the winding shaft 5, located on the outside of one of the fixed plates 4, and the rotating ratchet 6 has ratchet teeth 61; the pawl 62 is rotatably mounted on the outer wall of one of the fixed plates 4, and one end of the pawl 62 can extend between two adjacent ratchet teeth 61, and rotating the rotating ratchet 6 can drive the pawl 62 to rotate through the ratchet teeth 61; the mounting base 63 is disposed on the outer wall of one of the fixed plates 4, and the mounting base 63 has a mounting... The mounting cavity has an end opening; a mounting groove 64 is formed on the side of the pawl 62 opposite to the mounting seat 63; one end of the first elastic member 65 is installed in the mounting cavity and abuts against the inner bottom wall of the mounting cavity, and the other end is installed in the mounting groove 64 and abuts against the inner bottom wall of the mounting groove 64; a limiting shaft 66 is disposed on the outer wall of the fixing plate 4, and is positioned on the side of the pawl 62 away from the mounting groove 64; in the limiting state, the pawl 62 abuts against the limiting shaft 66 under the elastic thrust of the first elastic member 65, and the pawl 62 can prevent the rotating ratchet 6 from rotating in the opposite direction.

[0039] It also includes an operating handle 67, which is located at the other end of the pawl 62. When the limit needs to be released, the operating handle 67 is moved to drive one end of the pawl 62 to rotate toward the mounting base 63 and squeeze the first elastic member 65, so that one end of the pawl 62 disengages from the two adjacent ratchet teeth 61, thereby enabling the rotating ratchet 6 to rotate in the opposite direction.

[0040] like Figure 9 As shown, the operating structure includes a connector 52, a rotating handle 54, and a connecting cap 55. The connector 52 is fixedly sleeved on the other end of the winding shaft 5, located outside the other fixing plate 4. The connector 52 has a connecting through hole 53, and a through hole is also provided on the winding shaft 5 opposite to the connecting through hole 53. The rotating handle 54 passes through the connecting through hole 53 and the through hole on the winding shaft 5 and is installed on the connector 52. The end of the rotating handle 54 is provided with an external thread. The connecting cap 55 has an internal thread and is screwed to the end of the rotating handle 54, thereby installing the rotating handle 54 on the connector 52.

[0041] like Figure 7-9 As shown, the pre-compression structure includes a pre-compression component 7; wherein, the pre-compression component 7 is movably installed between the two fixed plates 4, and a concave arc surface 71 is provided below the pre-compression component 7 to match the winding shaft 5 for pre-compression.

[0042] It also includes limiting posts 72, second elastic elements 73, and limiting seats 74; wherein, there are two limiting posts 72, which are vertically arranged inside the pre-compression member 7 at a certain distance; there are two second elastic elements 73, one end of which is respectively sleeved on the limiting post 72; there are two limiting seats 74, which are arranged below the main body 3 and are vertically opposite to the two limiting posts 72; the limiting seat 74 has a limiting groove 75, which has a bottom opening, and the other end of the second elastic element 73 passes through the bottom opening and is installed in the limiting groove 75. When winding the restraint strap, the pre-compression member 7 continuously applies pressure to the restraint strap through the elastic thrust of the second elastic element 73, so that the restraint strap can be tightened evenly; when the patient pulls the restraint strap, the continuous pressure of the pre-compression member 7 can prevent the restraint strap from loosening due to external force.

[0043] It also includes a protective plate 8, which is detachably mounted on the fixed plate 4 on which the pawl 62 is installed; the protective plate 8 has an arc-shaped opening 81, and the operating handle 67 extends outward from the arc-shaped opening 81 and can move along the arc-shaped opening 81.

[0044] The quick-release and retraction structure of the restraint strap in this embodiment is used as follows: Before using it on a patient with impaired consciousness, first place the mounting plate 1 under the bed, then rotate the connecting bolt 15 inward to press the mounting plate 1 onto the bed. Then, adjust the restraint strap retraction seat 2 to the appropriate position according to the patient's height through the cooperation of the slide 11 and the slide groove 12. When using it on the patient, pass both ends of the restraint strap through the long strip opening 51 and then wind it onto the winding shaft 5. By rotating the handle 54 clockwise, rotate the winding shaft 5 to gradually tighten the restraint strap to a suitable tightness, thus completing the restraint of the patient. After reaching the appropriate tightness, stop rotating the winding shaft 5. The pawl 62 abuts against the limiting shaft 66 through the elastic thrust of the first elastic element 65. One end of the pawl 62 is restricted between two adjacent ratchet teeth 61, thereby limiting the winding shaft 5 and preventing it from rotating back. During the winding process, the pre-pressure element 7 continuously applies pre-pressure to the restraint strap. The restraint strap is evenly tightened on the winding shaft 5. The continuous pressure from the pre-compression member 7 prevents the restraint strap wrapped around the winding shaft from loosening. In case of an emergency requiring rapid release of the restraint, press down on the operating handle 67. One end of the pawl 62 rotates towards the mounting base 63 and squeezes the first elastic member 65, causing one end of the pawl 62 to disengage from the two adjacent ratchet teeth 61. Then, pull quickly along the extension direction of the restraint strap to allow the restraint strap to be quickly removed from the bed, thus ensuring that the patient can be evacuated quickly.

[0045] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this innovative technical solution.
