Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of mental illness treatment equipment, and particularly relates to a mental illness patient wearable restraint device. BACKGROUND

[0002] When mental illness patients are in the onset of the disease, they often lose effective control over their own behavior, and some patients may fall into an extremely excited and agitated state, exhibiting dangerous behaviors such as attacking others, self-injury, and self-harm. Some other patients may exhibit behavioral disorders and cognitive impairment, and are unable to normally cooperate with treatment and nursing work. These behaviors not only seriously threaten the life safety and physical health of the patients themselves, but also bring great difficulties and risks to the treatment and nursing work of medical staff.

[0003] In order to ensure the safety of mental illness patients during the onset of the disease and at the same time ensure the smooth progress of treatment and nursing work, it is necessary to restrain the patients. In the related art, a patient limb and trunk restraint device is disclosed in Chinese patent CN221814579U. The patient limb and trunk restraint device includes two upper limb wearers, two lower limb wearers, and four belt reeling devices. The belt reeling device uses an existing automobile safety belt reeling device. The restraint belt of the belt reeling device is connected to the upper limb wearer / lower limb wearer. After the patient wears the upper limb wearer and the lower limb wearer, the restraint belt of the belt reeling device restricts the slow movement of the patient's limbs within a permissible range, further avoids the patient from making harmful actions, and ensures the safety of the patient.

[0004] However, the above-mentioned patient limb and trunk restraint device also has some problems in actual use: when the patient moves slowly, based on the working characteristics of the belt reeling device, the restraint belt basically does not have the expected restraining effect on the patient's limb movement, which undoubtedly affects the normal nursing work of medical staff and increases the risk and difficulty in the nursing process; when the patient moves violently, due to the working characteristics of the belt reeling device, the restraint belt will be quickly and completely straightened, and in this case, the upper limb wearer and the lower limb wearer will generate excessive pressure on the patient's limbs, thereby easily causing damage to the patient's limbs and increasing the risk of life safety of the patient.

[0005] Moreover, the existing restraint device can only adapt to the shape of the patient's limbs in the circumferential direction, resulting in that the restraining effect on the patient's limbs mainly exists in the circumferential tension area. When the patient exerts force on the restraint device in the onset state, due to the limited contact area between the restraint device and the patient's limbs, a large pressure may be generated in the local area, which may cause excessive damage to the patient's limbs.

[0037] As attached Figures 1-10 As shown in the embodiment of the present invention, a wearable restraint device for patients with mental illness includes a retractable assembly 1, a restraint assembly 2, a fixing assembly 3, and a connecting strap 4. The connecting strap 4 is movably inserted through the retractable assembly 1. One end of the connecting strap 4 extends to one side and is fixed to the restraint assembly 2, and the other end of the connecting strap 4 extends to the other side and is fixed to the fixing assembly 3. In use, the restraint assembly 2 can be fitted onto the patient's limbs, and the fixing assembly 3 can be fitted onto a preset position, such as the railing of the bed, thereby forming a restraint state.

[0038] like Figure 5As shown, the winding assembly 1 comprises a base shell 11, a shell cover 12, a knob part 13, a winding part 14 and a coil spring 15. The shell cover 12 is arranged on the top of the base shell 11, the knob part 13 is inserted into the top of the shell cover 12, the winding part 14 is coaxial with the knob part 13 and arranged inside the base shell 11, the coil spring 15 is arranged between the shell cover 12 and the winding part 14 and connected with the knob part 13 and the winding part 14 respectively. The connecting belt 4 enters from one side wall of the base shell 11 and exits from the other side wall of the base shell 11. The part of the connecting belt 4 inside the base shell 11 is wound around the bottom of the winding part 14. The knob part 13 can move along the axis direction to make it clamped or unclamped with the shell cover 12. After the knob part 13 is unclamped, it can rotate around the axis to change the initial elastic force of the coil spring 15. The winding part 14 is driven to rotate by the coil spring 15, so as to adjust the tightness of the connecting belt 4 adaptively, and adjust the restraint force between the bed body and the patient.

[0039] As shown, Figure 4 The connecting belt 4 is provided with two stop blocks 41 in the length direction and arranged at the two sides of the base shell 11 outside the winding assembly 1 and form stop cooperation with the two sides of the base shell 11. When the winding assembly 1 is not tightened, the two stop blocks 41 on the connecting belt 4 are not close to the two sides of the base shell 11.

[0040] During use, after the restraint assembly 2 and the fixing assembly 3 are sequentially sleeved in the appropriate position, the hand holding part 131 of the knob part 13 is pulled outwards to make the first ring tooth 133 and the second ring tooth 121 unclamped. Then, the rotation number of the knob is adjusted according to the struggling degree of different patients. When the knob is rotated, the coil spring 15 is tightened, and when the coil spring 15 is tightened, the winding part 14 is driven to rotate, and when the winding part 14 is rotated, the connecting belt 4 is wound by the winding and unwinding rod 142 until the two stop blocks 41 are close to the two sides of the base shell 11 and form stop cooperation with the two sides of the base shell 11. With the continuous tightening of the coil spring 15, the connecting belt 4 in the base shell 11 is completely tensioned, so that the outer end of the coil spring 15 is fixed. With the continuous rotation of the knob part 13, the coil spring 15 is continuously tightened, so as to change the initial elastic force of the coil spring 15. Finally, the hand holding part 131 of the knob part 13 is inserted inwards to make the first ring tooth 133 and the second ring tooth 121 re-engage and clamp, so as to lock the knob part 13.

[0041] When the struggling degree of the patient is large, the force applied on the connecting belt 4 by the patient will also increase accordingly. At this time, the rotation number of the knob is adjusted, so that the coil spring 15 has a larger initial elastic force, which can effectively resist the external force applied by the patient, so that the connecting belt 4 is more difficult to stretch out of the base shell 11, and the restraint assembly 2 can tightly bind the patient's limbs under the pulling of the connecting belt 4, so as to prevent the patient from breaking free from the restraint due to excessive struggling, thereby ensuring the restraint effect and maximizing the safety of the patient himself and the surrounding personnel (such as medical staff).

[0042] When the patient struggles to a small degree, the force applied on the connecting belt 4 is relatively small, at this time, the number of rotations of the adjusting knob is adjusted, the coil spring 15 has a small initial elastic force, so that the connecting belt 4 is relatively easy to stretch out of the base shell 11, under the pulling of the connecting belt 4, the restraint belt assembly can not only ensure that the patient can be effectively restrained to prevent the patient from dangerous behavior due to loss of restraint, but also can give the patient a certain amount of freedom of movement to a certain extent.

[0043] In the specific embodiments of the present application, in order to improve the service life of the connecting belt 4, a protective layer 42 is sleeved on the outer periphery of the connecting belt 4; as shown in Figure 1 and Figure 4 The protective layer 42 is provided in a tubular structure and is divided into two sections, one section of the protective layer 42 is sleeved on the connecting belt 4 between the restraint assembly 2 and the base shell 11, and the other section of the protective layer 42 is sleeved on the connecting belt 4 between the fixing assembly 3 and the base shell 11.

[0044] Considering that the patient with mental illness may generate a large force when the disease occurs, in order to improve the restraint force on the patient, while being able to buffer the struggling force of the patient to a certain extent, and avoid causing excessive harm to the patient; the connecting belt 4 can be made of elastic materials such as natural rubber, polyurethane elastomer, etc., which have good elastic recovery performance and high strength, and can elastically deform under a certain tension, and quickly recover to the original state after the tension disappears.

[0045] During use, when the patient applies force to the connecting belt 4, the connecting belt 4 synchronously elastically stretches, the elastic stretching of the connecting belt 4 can absorb and buffer part of the force applied by the patient, avoiding that other components of the restraint device instantaneously bear excessive stress and be damaged or fail; at the same time, the elastic stretching of the connecting belt 4 will generate a reverse tension, which will increase with the increase of the force applied by the patient, thereby further enhancing the restraint force on the patient's limbs.

[0046] The top of the winding member 14 is provided with a mounting groove 141, and the bottom of the winding member 14 is vertically provided with two winding rods 142, and part of the connecting belt 4 penetrating the base shell 11 is commonly wound on the two winding rods 142, the coil spring 15 is arranged in the mounting groove 141, and the outer end thereof is connected and fixed with the circumferential side wall of the mounting groove 141.

[0047] In order to more clearly describe the positional relationship between the connecting belt 4 and the winding rod 142, as shown in Figure 4As shown, the two take-up and release rods 142 are placed at an interval from left to right. After the connecting strip 4 passes through the base shell 11, the part of the connecting strip 4 located inside the base shell 11 is folded in half to form two connecting strips 4. The two ends of the original connecting strip 4 remain unchanged, and the loop-shaped part formed by bending the middle section after folding is fitted onto the left take-up and release rod 142. One connecting strip 4 passes over the top of the left take-up and release rod 142, the top of the right take-up and release rod 142, and the right side in sequence, and finally passes down through the base shell 11 and extends outward. The other connecting strip 4 passes through the gap between the two take-up and release rods 142, passes over the top, right side, and bottom of the right take-up and release rod 142 in sequence, and then passes over the bottom, left side, and top of the left take-up and release rod 142, and finally passes up through the base shell 11 and extends outward. Thus, the part of the connecting strip 4 located inside the base shell 11 can be wound around the two take-up and release rods 142. When the take-up member 14 is driven to rotate, the two take-up and release rods 142 can take up and release the connecting strip 4.

[0048] The knob 13 has a handle 131 at its top and a connecting part 132 at its bottom. The connecting part 132 has a first ring tooth 133 on its outer periphery and a columnar protrusion 134 at its bottom center. The top of the cover 12 has a latch that matches the connecting part 132. The circumferential sidewall of the latch has a second ring tooth 121 that matches the first ring tooth 133. Initially, the knob 13 engages with the second ring tooth 121 of the cover 12 through the first ring tooth 133. The columnar protrusion 134 passes through the latch, abuts against the top of the winding member 14, and is connected and fixed to the inner end of the coil spring 15.

[0049] Optionally, such as Figure 1 As shown, to prevent slipping, several strip-shaped protrusions are provided on the outer peripheral sidewall of the handgrip 131.

[0050] In a specific embodiment of the present invention, such as Figure 2 and Figure 3 As shown, the restraint assembly 2 includes a first restraint member 21 and a second restraint member 22. The second restraint member 22 is inserted into the first restraint member 21. One end of the connecting strap 4 passes through the first restraint member 21 and is connected and fixed to the second restraint member 22. In this way, the dual restraint of the first restraint member 21 and the second restraint member 22 can effectively prevent the restraint device from coming loose due to the patient's exertion of force, enhance the stability and reliability of the restraint on the patient's limbs, reduce the life safety risk of the patient due to restraint failure, and at the same time reduce the difficulty of nursing work for medical staff and improve the efficiency and safety of nursing work.

[0051] The first constraint 21 comprises an elastic constraint band 211 and detachable connectors 212, the detachable connectors 212 are respectively arranged at two ends of the elastic constraint band 211, the two ends of the elastic constraint band 211 are connected to form a first annular structure through the detachable connectors 212, the inside of the elastic constraint band 211 is hollow, and the second constraint 22 is arranged in the inside of the elastic constraint band 211; in order to guarantee the constraint effect of the constraint assembly 2, the elastic constraint band 211 is in a tension state during use, which can be approximately regarded as a rubber band in an expansion state, so that when a patient's limb is constrained, the constraint assembly 2 can avoid the occurrence of a circumferential overlapping area and an inward protruding part, thereby effectively avoiding the discomfort or even the pressure injury of the patient caused by the existence of the inward protruding part.

[0052] Optionally, the detachable connectors 212 can be connected in cooperation with magic hooks and magic tapes, can be connected in cooperation with adhesive tapes, and can also be connected in cooperation with hooks and hanging rings.

[0053] Specifically, as shown in Figure 6 The second constraint 22 comprises a plurality of chain links 221 and a plurality of pin shafts 222, the plurality of chain links 221 are hingedly connected through the pin shafts 222 to form a detachable second annular structure, so that the constraint assembly 2 can be flexibly adjusted according to different sizes and shapes of patient's limbs, is suitable for patients of different body types, has good universality, and one end of the connecting band 4 is fixed on an outer arc surface of one of the chain links 221 of the second constraint 22.

[0054] Each chain link 221 is provided with a protruding plug on one side wall surface and is provided with a plug hole on the other side wall surface, and optionally, in order to guarantee the structural strength and rationality of the protruding plug of the chain link 221, the plug hole can be arranged in the middle of the chain link 221; when adjacent chain links 221 are connected and installed, the protruding plug of the latter chain link 221 is inserted into the plug hole of the former chain link 221, and then the pin shaft 222 is simultaneously inserted and installed on the protruding plug and the plug hole of the adjacent chain links 221.

[0055] Exemplarily, the number of chain links 221 can be eighteen, and the eighteen chain links 221 are arranged in a circumferential direction; during use, a corresponding number of pin shafts 222 can be pulled out according to the thickness of the patient's limb, then a corresponding number of chain links 221 are detached, then the protruding plugs and the plug holes of the two chain links 221 located at two ends of the remaining connected chain links 221 are inserted and connected and are fixed through any pin shaft 222, so that the remaining connected chain links 221 can form a second annular structure, and the second annular structure can be sleeved on the patient's limb; it can be understood that the number of chain links 221 can also be adjusted in advance according to the thickness of the patient's limb.

[0056] In the specific embodiments of the present application, as Figure 6As shown, each chain link 221 is arranged as an arc-shaped block structure, and each chain link 221 is provided with a mounting seat 223 on the inner side, and each mounting seat 223 is provided with a hinge column 224 on the left and right sides, and the mounting seat 223 is hinged to the inner side of the chain link 221 through the hinge column 224, and each mounting seat 223 is provided with a support strip 225 on the upper and lower sides respectively.

[0057] The mounting seat 223 and the chain link 221 are hingedly matched, so that the mounting seat 223 can rotate by a certain angle relative to the chain link 221, so that the plurality of support strips 225 can form a circular table structure, and then can adapt to the circular table shape of the patient's limb, and support the patient's limb in the extension direction of the patient's limb; in use, the linkage cooperation between the mounting seat 223 and the support strip 225 and the first and second annular structures can not only realize the circumferential contact and fixation of the patient's limb, but also realize the axial contact and fixation of the patient's limb, thereby increasing the contact area between the patient's limb and the patient's limb, and facilitating the dispersion of the contact pressure between the patient's limb and the patient's limb.

[0058] Specifically, the actual shape and contour of the patient's limb can be adaptively adjusted, and if the patient's limb has a certain degree of curvature or irregular shape, the mounting seat 223 can be flexibly rotated under the action of the hinge to make the support strip 225 closely fit the surface of the patient's limb, thereby more effectively dispersing the pressure of the restraint device on the patient's limb and avoiding excessive local pressure. At the same time, the hinge cooperation can also ensure that the support strip 225 can rotate accordingly with the movement of the limb when the patient's limb moves to a certain extent, without causing excessive restriction on the patient's normal activities, further improving the comfort and adaptability of the mental illness patient wearing the restraint assembly 2.

[0059] During use, when the restraint assembly 2 is sleeved on the patient's limb, the support strips 225 on the plurality of chain links 221 of the second restraint member 22 can form a continuous support surface along the extension direction of the patient's limb, which greatly increases the contact area with the patient's limb compared with the existing restraint mode relying only on circumferential tension; when the patient exerts force on the restraint device, due to the increase in the contact area, according to the pressure formula (P=F / S), the pressure will be dispersed to a larger area, and the local pressure will be reduced, thereby effectively avoiding the occurrence of excessive damage to the patient's limb. At the same time, the arrangement of the support strips 225 along the extension direction of the patient's limb can better adapt to the shape and movement characteristics of the patient's limb, provide effective restraint while giving the patient a certain activity space, improve the comfort of the patient wearing the restraint device, and also facilitate the treatment and nursing operation of medical staff, reduce the resistance of the patient due to discomfort, and further improve the effect and quality of the treatment and nursing work of the mental illness patient.

[0060] In further embodiments of the present application, as shown in Figures 7-10 The mounting base 223 is provided with a liquid bag 226, which is arranged on the inner side wall of the mounting base 223 so as to be in contact with the patient's limb. The mounting base 223 and the liquid bag 226 are filled with fluid and are in communication with each other. The mounting base 223 is provided with sliding rods 227 on the upper and lower sides. One end of the sliding rod 227 is inserted into the mounting base 223 and forms a piston stop cooperation structure with the mounting base 223. The other end of the sliding rod 227 extends out of the mounting base 223 and is connected to the support bar 225, which can extend and slide along the extension direction of the support bar 225.

[0061] The support bar 225 is provided in an M-shaped structure, with both ends fixed to the mounting base 223 and the middle part connected to the other end of the sliding rod 227.

[0062] In order to improve the patient's experience when the support bar 225 supports the patient's limb and ensure the support effect of the support bar 225, the support bar 225 can be provided with an outer layer structure and an inner layer structure, with the outer layer structure sleeved on the inner layer structure.

[0063] The outer layer structure can be made of elastic material, such as rubber, which has good elasticity and flexibility. When the support bar 225 is in contact with the patient's limb, the elasticity of the outer layer can play a buffering role, reducing the impact damage of the inner layer to the patient's limb. During the patient's illness, the patient's limb movements are often uncontrollable and violent. At this time, the elastic buffer of the outer layer can effectively avoid the hard extrusion or collision of the support bar 225 to the patient's limb, thereby improving the comfort of the patient and reducing the risk of physical injury caused by restraint.

[0064] At the same time, the inner layer structure can be provided in a chain-like structure. Under the rigid support of the chain-like structure, the support bar 225 cannot be deformed perpendicular to the extension direction of the support bar 225. At the same time, under the support of the outer layer structure, the inner layer chain-like structure can maintain an M shape, thereby ensuring the stability of the support to the patient's limb.

[0065] During use, when the liquid bag 226 is pressed by the patient's limb, the liquid bag 226 and the fluid in the mounting base 223 can push the sliding rods 227 on the upper and lower sides to slide outward, respectively, and push the middle part of the support bar 225 to move outward, thereby increasing the length of the support bar 225 and increasing the contact area between the support bar 225 and the patient's limb. In this way, when the patient's struggling force is large, the length of the support bar 225 is increased, and the contact area between the support bar 225 and the patient's limb is further increased, which is beneficial to further dispersing the contact pressure between the patient's limb and the mental illness patient wearing the restraint device.

[0066] When the liquid bag 226 is not pressed by the patient's limb, the liquid bag 226 is automatically reset under the elastic effect, so that a negative pressure appears in the mounting seat 223, and then a pressure difference appears on the two sides of the mounting seat 223, under the action of the external atmospheric pressure, the sliding rods 227 on the upper and lower sides slide inward, so that the supporting strips 225 return to the original length.

[0067] The fixing assembly 3 comprises a fixing belt 31, a lock frame 32 and an insertion rod (not shown in the figure), the lock frame 32 is fixed to one end of the fixing belt 31, the other end of the fixing belt 31 is provided with a plurality of lock holes 311, the insertion rod is installed in the lock frame 32 and can elastically slide in a direction perpendicular to the belt surface of the fixing belt 31 to be inserted into one of the lock holes 311 at the other end of the fixing belt 31; wherein the lock frame 32 is hollow inside to enable the other end of the fixing belt 31 to pass through the lock frame 32.

[0068] Specifically, in order to facilitate the elastic sliding of the insertion rod, the fixing assembly 3 further comprises a compression spring (not shown in the figure), the compression spring is installed in the lock frame 32 and connected between the lock frame 32 and the insertion rod; under the action of the compression spring, the insertion rod has a tendency to be inserted into the lock hole 311; in the use process, the fixing belt 31 is wound on the rail of the bed body, the other end of the fixing belt 31 passes through the lock frame 32, the belt surface presses the insertion rod to retract into the lock frame 32 during the sliding process, when one of the lock holes 311 is placed below the insertion rod, the insertion rod is inserted into the lock hole 311 under the action of the compression spring, so as to realize that the fixing belt 31 is sleeved on the rail of the bed body, and the tightness of the fixing belt 31 can be adaptively adjusted.
