Description

Technical Field

[0001] The present invention relates to the technical field of medical auxiliary supplies, and particularly relates to a rapid retracting and releasing structure for a restraint belt and a restraint device. Background Art

[0002] The aimless abnormal behaviors caused by loss of orientation or hallucinations in patients with disturbance of consciousness have become the key prevention and control links in clinical nursing safety management. In disease states such as delirium, hepatic encephalopathy, or hypoglycemic coma, due to acute cognitive dysfunction and loss of behavior control ability, patients often show complex clinical manifestations: the mild ones are manifested as restlessness and repeated attempts to get out of bed, and the severe ones may have a sudden increase in the risk of falling out of bed due to spatial orientation errors, or self-harming scratching, hitting and other behaviors induced by persecutory delusions, or even aimless aggressive tendencies due to agitated mental symptoms.

[0003] The phenomenon of behavioral out-of-control not only threatens the safety of the patients themselves, but also increases the difficulty of nursing operations. Comprehensive management needs to be implemented through means such as early identification of the characteristics of the primary disease, dynamic assessment of the consciousness state, reasonable use of protective restraints and drug interventions. Currently, the commonly used restraint garments in clinical practice (refer to Figure 14 as shown) are used to fix the upper body of the patient to prevent falling out of bed, self-harm or harming others; however, the problem with this kind of restraint garment is that covering the upper body of the patient will make it difficult for medical staff to directly observe the skin condition of the patient, the wound condition and whether the infusion tube under the clothes is compressed, which is not conducive to timely detection of abnormalities; for patients with a larger body size, the binding straps of the restraint garment may cause a sense of compression after being fixed, resulting in a decrease in the comfort of the patient; in the prior art, there are also cases where the limbs of the patient are restrained separately with binding straps, but the operation is not convenient enough when releasing, and rapid release cannot be achieved in case of an emergency.

[0004] Therefore, how to design a rapid retracting and releasing structure for a restraint belt that can visually observe the patient's condition, timely detect abnormalities, and improve the comfort of the patient is a technical problem that has not been solved in the prior art. Summary of the Invention

[0040] The following will describe this application in detail with reference to the drawings and in combination with embodiments. Embodiment 1

[0041] This embodiment provides a fast winding and unwinding structure for a restraint belt, as Figures 1-4 shown, including: a mounting plate 1 and a restraint belt winding and unwinding seat 2; at least one mounting plate 1 is suitable for being mounted under at least one side of a hospital bed; the restraint belt winding and unwinding seat 2 is movably mounted under the mounting plate 1, and includes a main body member 3, a movable mounting structure, a fixing plate 4, a winding shaft 5, a limiting structure, an operating structure and a preloading structure; wherein, an internally threaded through hole is formed in the main body member 3; the movable mounting structure is arranged above the main body member 3 and is used for movably mounting with the mounting plate 1; there are two fixing plates 4, which are fixedly arranged under the main body member 3 and are arranged oppositely; the winding shaft 5 is rotatably mounted on the two fixing plates 4 and is used for winding the restraint belt; the limiting structure is arranged outside one of the fixing plates 4 and is used for limiting the rotation of the winding shaft 5; the operating structure is arranged outside the other fixing plate 4 and is used for operating the rotation of the winding shaft 5; the preloading structure is arranged on the main body member 3 between the two fixing plates 4 and above the winding shaft 5 and is used for preloading the restraint belt wound on the winding shaft 5.

[0042] Before using it on patients with impaired consciousness, first install the mounting plate 1 on both sides of the hospital bed, and then adjust the belt retractor seat 2 to an appropriate position according to the patient's height. After adjustment, use the dovetail bolt to threadedly connect with the internal thread through hole, and rotate the dovetail bolt inward to abut against the hospital bed, so as to limit and fix the belt retractor seat 2; alternatively, installation threaded holes corresponding to the internal thread through holes are also opened on the hospital bed, and after the dovetail bolt passes through the internal thread through hole, it continues to be threadedly connected with the installation threaded hole, so as to achieve more stable limit fixation. When using it on patients, wind the two ends of the restraint belt around the winding shaft 5 respectively, and gradually tighten the restraint belt to an appropriate tightness by operating the structure to rotate the winding shaft 5 clockwise to complete the restraint of the patient; stop rotating the winding shaft 5 after reaching the appropriate tightness, and the limit structure locks the winding shaft 5 to prevent rotation; during the winding process, the preloading structure continuously applies a pre-pressure to the restraint belt, so that the restraint belt is evenly tightened on the winding shaft 5; through the continuous pressure of the preloading structure, the restraint belt wound around the winding shaft can be prevented from loosening. Compared with the traditional restraint gown, the restraint belt quick retraction and release structure of this embodiment is used in cooperation with the restraint belt. While ensuring effective restraint of the patient, it is convenient for medical staff to directly observe the patient's physical signs changes to identify abnormal conditions, and can accurately adjust the restraint tightness, avoid discomfort caused by improper pressure, and can also achieve quick retraction and release, with convenient operation.

[0043] As Figure 3 shown, the movable mounting structure includes a slideway 11 and a chute 12; wherein, the slideway 11 is arranged below the mounting plate 1; the chute 12 is opened above the main body part 3, and the chute 12 is matched and installed with the slideway 11 and can slide along the slideway 11, so that the main body part 3 and the mounting plate 1 are movably installed.

[0044] The two fixing plates 4 are oppositely provided with rotation through holes 41, and the winding shaft 5 is rotatably installed on the two fixing plates 4 through the rotation through holes 41; the winding shaft 5 is provided with a long strip opening 51 penetrating through both sides, and the restraint belt is adapted to pass through the long strip opening 51 and can be wound around the winding shaft 5 when the winding shaft 5 rotates. After the restraint belt passes through the long strip opening 51 and is wound, it is not necessary to fix the restraint belt on the winding shaft 5, and automatic pressing can be achieved when the winding shaft 5 rotates.

[0045] As Figures 5-6As shown in the figure, the limiting structure includes a rotating ratchet wheel 6, a pawl 62, a mounting seat 63, a mounting groove 64, a first elastic member 65 and a limiting shaft 66. Among them, the rotating ratchet wheel 6 is fixedly arranged at one end of the winding shaft 5, outside one of the fixing plates 4. The rotating ratchet wheel 6 has ratchet teeth 61. The pawl 62 is rotatably mounted on the outer wall of one of the fixing plates 4, and one end of the pawl 62 can extend between two adjacent ratchet teeth 61. The mounting seat 63 is arranged on the outer wall of one of the fixing plates 4. The mounting seat 63 has a mounting cavity with an end opening. The mounting groove 64 is opened on the side of the pawl 62 opposite to the mounting seat 63. One end of the first elastic member 65 is mounted in the mounting cavity and abuts against the inner bottom wall of the mounting cavity, and the other end is mounted in the mounting groove 64 and abuts against the inner bottom wall of the mounting groove 64. The limiting shaft 66 is arranged on the outer wall of one of the fixing plates 4, and is arranged on the other 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 wheel 6 from rotating in the reverse direction. It further includes an operating handle 67, and the operating handle 67 is arranged at the other end of the pawl 62. When it is necessary to release the limit, the operating handle 67 is toggled to drive one end of the pawl 62 to rotate towards the direction close to the mounting seat 63 and compress the first elastic member 65, so that one end of the pawl 62 disengages from between two adjacent ratchet teeth 61, and then the rotating ratchet wheel 6 can rotate in the reverse direction.

[0046] As Figure 9 shown in the figure, the operating structure includes a connecting head 52, a rotating handle 54 and a connecting cap 55. Among them, the connecting head 52 is fixedly sleeved at the other end of the winding shaft 5, outside the other fixing plate 4. The connecting head 52 is provided with a connecting through hole 53, and a through hole is also opened on the winding shaft 5 opposite to the connecting through hole 53. The rotating handle 54 is installed on the connecting head 52 after passing through the connecting through hole 53 and the through hole opened on the winding shaft 5. The end of the rotating handle 54 is provided with an external thread. The inner part of the connecting cap 55 is provided with an internal thread and is screwed with the end of the rotating handle 54, so as to install the rotating handle 54 on the connecting head 52.

[0047] As Figures 7-9As shown in the figure, the preloading structure includes a preloading member 7, a limiting post 72, a second elastic member 73, and a limiting seat 74. Among them, the preloading member 7 is movably installed up and down between the two fixing plates 4. An inner concave arc surface 71 capable of preloading in matching with the winding shaft 5 is provided below the preloading member 7. There are two limiting posts 72, which are vertically arranged inside the preloading member 7 at a certain distance apart. There are two second elastic members 73, one end of each of which is sleeved on the limiting post 72 respectively. There are two limiting seats 74, which are arranged below the main body member 3 and are vertically opposite to the two limiting posts 72. The limiting seat 74 has a limiting groove 75, and the limiting groove 75 has an opening at the bottom. The other end of the second elastic member 73 passes through the bottom opening and is installed in the limiting groove 75. When winding the restraint belt, the preloading member 7 continuously applies pressure to the restraint belt through the elastic thrust of the second elastic member 73, so that the restraint belt can be evenly tightened. When the patient pulls the restraint belt, through the continuous pressure applied by the preloading member 7, it can prevent the restraint belt from loosening due to external force.

[0048] The usage method of the restraint belt quick retracting and releasing structure in this embodiment is as follows: Before using it on a patient with impaired consciousness, first install the mounting plate 1 on both sides of the hospital bed, and then adjust the belt retracting and releasing seat 2 to an appropriate position according to the patient's height through the cooperation of the slideway 11 and the chute 12. When using it on the patient, pass the two ends of the restraint belt through the long strip opening 51 respectively and wind them on the winding shaft 5. Rotate the winding shaft 5 clockwise by turning the handle 54 to gradually tighten the restraint belt to a suitable tightness to complete 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 member 65. One end of the pawl 62 is restricted between two adjacent ratchet teeth 61, thereby limiting the winding shaft 5 to prevent it from rotating back. During the winding process, the preloading member 7 continuously applies a preload to the restraint belt, so that the restraint belt is evenly tightened on the winding shaft 5.
