Description

Technical Field

[0001] This utility model belongs to the field of medical and nursing device technology, specifically an adjustable and multifunctional protective restraint device for psychiatry. Background Technology

[0002] In psychiatric care, patients sometimes exhibit agitation, aggression towards others, or self-harm due to the specific nature of their condition. To protect the safety of patients and those around them, healthcare professionals need to implement appropriate restraint measures. These measures must effectively limit the patient's freedom of movement while ensuring their comfort and safety.

[0003] Traditional restraint tools, such as ropes and straps, while meeting restraint needs to some extent, have many limitations. For example, ropes and similar tools can easily leave marks on the skin during a patient's struggle, or even cause skin abrasions, resulting in significant pain. Furthermore, these traditional restraint tools cannot guarantee the patient's safety and comfort during restraint. Even more professional restraint tools, such as limb restraint belts, which can wrap around the patient's limbs and restrict movement with fixing straps, still use buckle-locking fasteners. This may not perfectly conform to the patient's limb contours, leading to situations where the belt is too loose and slips off, or too tight and restricts blood flow and causes friction damage to the patient's skin. Moreover, medical staff must use a key to open the buckles on the surface of the restraint belt to adjust the tightness, a cumbersome operation that also increases the risk of the patient breaking free, threatening the personal safety of medical staff.

[0004] Therefore, it is necessary to propose a psychiatric adjustable multi-functional protective restraint device that can conveniently adjust and lock the tightness of the restraint strap on the patient's limbs at any time, and can adjust the tightness without any settings to achieve the best wrapping effect of the restraint strap on the patient's limbs, reducing the risk of the patient breaking free while improving the comfort of the restraint strap. Utility Model Content

[0005] To address the aforementioned problems, the purpose of this invention is to provide an adjustable, multifunctional protective restraint device for psychiatric patients. By pressing a knob to unlock and rotating it to adjust the length of the adjustment strap, and releasing the knob to relock, the patient's limbs are wrapped in the appropriate tightness of the adjustment strap. The length of the fixing strap can be adjusted using a length adjuster, enhancing the convenience and safety of the adjustment operation and improving the efficiency and quality of psychiatric nursing work.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows: A psychiatric adjustable multifunctional protective restraint device includes a restraint belt and a fixing belt. An adjustment component is provided on one side of the restraint belt, and the side of the adjustment component away from the restraint belt is fixedly connected to the fixing belt. The other end of the fixing belt is connected to a nursing bed.

[0007] The adjustment assembly includes an adjustment kit axially fixedly sleeved on one side of the constraint band. A locking spring is fixedly connected to the center of the outer surface of the adjustment kit. A knob is slidably connected to the end of the locking spring away from the adjustment kit. An axial toothed ring is fixedly connected to the side of the knob near the locking spring. An adjustment shaft is engaged with the side of the axial toothed ring near the adjustment kit. The adjustment shaft passes vertically through the adjustment kit and the constraint band and is rotatably connected to the inner walls on both sides of the adjustment kit. A toothed belt assembly is engaged with the adjustment shaft located in the adjustment kit. Several locking grooves facing the adjustment shaft are opened inside the outer wall of the adjustment kit. Locking arc strips are slidably fitted in each locking groove. Locking teeth are fixedly connected to the end of each locking arc strip near the adjustment shaft. Arc strip springs are axially fixedly connected to the end of each locking arc strip away from the locking teeth. The other end of each arc strip spring is fixedly connected to the inner wall of the corresponding locking groove. A sliding arc block is fixedly connected to the side of each locking arc strip near the knob. Circumferential tooth grooves corresponding to the locking teeth are opened on the outer periphery of the adjustment shaft. The locking teeth are engaged with the circumferential tooth grooves.

[0008] The basic principle is as follows: Medical staff press the knob, pushing the sliding block and locking arc strip to compress the arc strip spring and disengage the adjusting shaft. Rotating the knob drives the adjusting shaft to rotate via the axial toothed ring, engaging the adjusting shaft with the toothed belt assembly, thereby tightening or loosening the restraint belt. When adjusted to the appropriate position, the knob is released, the locking spring pushes the knob back to its original position, and simultaneously the sliding block and locking arc strip are pushed back to the locked position by the arc strip spring. The locking teeth engage with the circumferential grooves of the adjusting shaft, locking the position of the adjusting shaft.

[0009] The basic solution offers the following benefits: 1. Through the innovative combination of knobs and adjusting shafts, medical staff can easily and quickly adjust the tightness of the restraints without complicated operating procedures or additional tools, greatly saving time. During adjustment, the precise meshing of the toothed belt assembly and the adjusting shaft ensures accuracy, avoiding the problems of inaccurate or over-adjustment common in traditional restraint devices.

[0010] 2. The ingenious design of the locking arc and locking teeth achieves a dual locking mechanism for the adjustment shaft. When the knob is not pressed, the locking arc, under the action of the lever spring, tightly locks the adjustment shaft, ensuring that the adjustment shaft will not rotate on its own due to the patient's struggle or accidental touch, effectively preventing the safety risks caused by the restraint straps accidentally loosening. The linkage design between the sliding arc block and the knob requires a clear pressing action for unlocking, avoiding the possibility of misoperation and further improving safety performance.

[0011] 3. The tightness of the restraints can be precisely adjusted according to the patient's body shape and comfort needs, avoiding the pressure or discomfort caused by the fixed length of traditional restraint devices. The restraints are made of soft and wear-resistant materials, reducing friction with the patient's skin, lowering the risk of skin damage, and improving the patient's overall comfort.

[0012] 4. The multi-functional design of this restraint device allows medical staff to flexibly choose the restraint method and location according to the specific situation of different patients, thereby improving the pertinence and effectiveness of nursing work.

[0013] Furthermore, the toothed belt assembly includes several gear disks rotatably connected to the inner wall of the adjustment kit. Adjacent gear disks mesh with each other, and the two gear disks in the center of the adjustment kit mesh with the adjustment shaft. Each gear disk has a triangular shaft coaxially fixedly connected to one side. The triangular shafts pass through the constraint belt and are rotatably connected to the inner wall of the other side of the adjustment kit. The constraint belt has an annular cavity inside, and several adjustment belts corresponding to the gear disks slide in the annular cavity. Both ends of the adjustment belts are fixedly connected to the two sides of the corresponding triangular shafts.

[0014] The beneficial effects of the basic scheme are: 1. By introducing several gear discs that are rotatably connected to the inner wall of the adjusting kit and meshing with each other, a highly efficient transmission system is formed. This design not only ensures that the adjusting shaft can precisely drive all gear discs to rotate synchronously when rotating, but also further amplifies the driving force of the adjusting shaft through the cascading effect of the gear discs, making the tightening or loosening process of the adjusting belt faster and smoother.

[0015] 2. The triangular shaft coaxially fixedly connected to one side of the gear disk, and the adjusting belt fixedly connected to the triangular shaft, form a stable triangular winch structure, which enhances the stability and durability of the adjusting belt. The adjusting belt can slide freely in the annular cavity, improving the flexibility and accuracy of adjustment.

[0016] 3. The annular cavity design not only provides sufficient sliding space for the adjustment belt but also makes the entire restraint device more compact, reducing unnecessary space occupation. This design facilitates rapid operation by medical staff during care and makes the restraint device more suitable for installation on nursing beds of various sizes, improving its applicability and flexibility. The compact layout of the gear disc and triangular shaft, and their ingenious connection with the restraint belt and adjustment kit, ensures that the entire adjustment assembly maintains efficient transmission while possessing good structural strength and stability, guaranteeing reliability and safety under long-term use.

[0017] 4. The precise adjustment function of the straps allows medical staff to make personalized adjustments based on the patient's specific condition and comfort needs. This design not only helps reduce patient discomfort and pressure during restraint but also improves their overall comfort and satisfaction.

[0018] Furthermore, an axial connecting belt is slidably fitted inside the annular cavity on the side away from the adjusting kit, and the connecting belt and the adjusting belt are fixedly connected.

[0019] The beneficial effects of the basic design are as follows: 1. The clever design of the connecting belt connects the adjusting belt within the annular cavity, forming a more stable overall structure. This not only enhances the stability of the adjusting belt during sliding but also improves the structural strength and durability of the entire constraint device. The fixed connection between the connecting belt and the adjusting belt ensures that all adjusting belts can respond synchronously and uniformly to the movement of the adjusting shaft during adjustment, guaranteeing the accuracy and consistency of the adjustment. This design helps reduce errors and deviations during the adjustment process, improving the precision and reliability of the adjustment.

[0020] 2. The sliding fit design of the connecting strap within the annular cavity allows the adjustment strap to move more flexibly and smoothly when tightening or loosening. This design not only improves the adjustment response speed but also allows the restraint device to better distribute the pressure force during restraint through the area of ​​the connecting strap, forming a more uniform and stable pressure distribution, which helps reduce the patient's discomfort and pressure during the restraint process.

[0021] Furthermore, the outer edge of the knob near the adjustment kit and the sliding block are in sliding engagement.

[0022] The advantages of the basic design are: 1. The sliding engagement between the knob and the sliding block allows the knob to smoothly push the sliding block during circumferential movement, thereby locking or unlocking the adjustment shaft. This design not only simplifies the operation steps but also makes the adjustment process smoother and more efficient.

[0023] 2. The sliding engagement design of the knob and the sliding block makes the entire adjustment assembly more compact and rational in structure. This design reduces unnecessary space occupation and improves the overall reliability and practicality of the restraint device.

[0024] Furthermore, protective blocks located on both sides of the knob are fixedly connected to the outer wall of the adjustment kit, and the protective blocks are fixedly connected to the fixing strap.

[0025] The beneficial effects of the basic design are: 1. The protective blocks are cleverly designed and located on both sides of the knob, and are fixedly connected to the fixing strap, forming an effective protective barrier. This not only prevents medical staff from accidentally turning the knob due to mis-touching or improper operation during adjustment, but also prevents patients or other personnel from accidentally touching the knob, thereby reducing the risk of accidental unlocking or adjustment and enhancing operational safety.

[0026] 2. The secure connection between the protective block and the fixing strap not only strengthens the connection between the adjustment kit and the fixing strap, but also makes the entire restraint apparatus structurally more stable and reliable. This design helps reduce structural loosening or damage caused by prolonged use or accidental impacts, extending the service life of the restraint apparatus.

[0027] 3. The protective block is designed with ergonomic principles in mind. Its shape and position have been carefully designed and adjusted to ensure that medical staff can comfortably hold and operate the knob. This not only improves the convenience and efficiency of operation but also reduces hand fatigue or discomfort caused by prolonged operation, thus optimizing the user experience.

[0028] Furthermore, the end of the adjusting shaft near the knob has an axial toothed groove, which meshes with the axial toothed ring.

[0029] The beneficial effects of the basic design are: 1. The meshing design of the axial toothed groove and axial toothed ring allows the rotational action of the knob to be precisely transmitted to the adjusting shaft, thereby achieving fine adjustment of the constraint belt. This design reduces errors and deviations during the adjustment process and improves the accuracy of adjustment. The meshing transmission method has high stability and reliability, ensuring that the transmission relationship between the adjusting shaft and the knob remains consistent during long-term use. This helps to reduce safety hazards caused by transmission failure.

[0030] 2. The restraint straps can be quickly adjusted by rotating the knob. This one-button operation simplifies the process and reduces the steps and time costs for medical staff. The meshing transmission design allows the rotation of the knob to be quickly transmitted to the adjustment shaft, resulting in a rapid response to the restraint straps. This helps improve the work efficiency of medical staff, especially in emergency situations.

[0031] 3. The meshing design of the axial toothed groove and axial toothed ring makes the knob and adjusting shaft easier and quicker to disassemble and assemble. This helps medical staff perform regular maintenance and cleaning. The simplified structure and easy-to-disassemble design reduce maintenance and time costs, making restraint equipment more economical and practical.

[0032] Furthermore, the outer diameter of the triangular shaft is smaller than the outer diameter of the gear disk.

[0033] The beneficial effects of the basic design are: 1. The difference in outer diameter between the triangular shaft and the gear disc makes the entire transmission system more compact in structure. This helps reduce the space occupied by the triangular shaft during the rotation of the winch adjustment belt, making the restraint device smaller, lighter, and easier to carry and store.

[0034] 2. When locked, the tension of the adjusting belt on the triangular bearing is distributed to the gear disk, thereby reducing the load of the adjusting shaft locking.

[0035] Furthermore, the inner and outer walls of the restraint straps and adjustment kits are covered with flexible layers.

[0036] The benefits of the basic solution are: 1. The flexible layer makes the restraints and adjustment kits softer and more conforming to the patient's skin when in contact, effectively reducing the pressure and discomfort that may be caused by traditional rigid materials. The flexible layer is usually made of breathable materials, which helps keep the skin in the restraint area dry and comfortable, reducing problems such as skin dampness and itching caused by prolonged restraint.

[0037] 2. The presence of a flexible layer prevents the edges of the restraint straps and adjustment kit from directly rubbing against the patient's skin, effectively preventing abrasions and skin damage. The flexible layer can evenly distribute the pressure of the restraint straps on the patient's body, reducing excessive local pressure and helping to protect the patient's skin from injury.

[0038] 3. The softness and conformability of the flexible layer make the restraint straps more comfortable for patients, reducing their feeling of constraint and anxiety, and helping to improve the smoothness of the treatment process. Although the flexible layer increases the softness of the restraint straps, its material and design still ensure the restraint straps' fixation effect, preventing patients from accidentally breaking free or causing other safety hazards.

[0039] Furthermore, the fixing strap is fixedly connected to the nursing bed via a length adjuster.

[0040] The beneficial effects of the basic solution are: 1. The introduction of the length adjuster allows the restraint straps to be flexibly adjusted according to the patient's body shape, height, and the specific position of the nursing bed. This design ensures that the restraint device can tighten the patient and the nursing bed to restrain limb movement, improving the stability and safety of the restraint. Regardless of the patient's body size or the type of nursing bed, the length adjuster can achieve a suitable fit for the restraint straps. This wide applicability makes the restraint device suitable for different scenarios and patient groups, increasing its practical value.

[0041] 2. The length adjuster allows the restraint straps to maintain sufficient restraint while reducing excessive constriction on the patient's body. This design helps reduce the patient's feeling of restraint and discomfort, improving their comfort during treatment. The length adjuster allows the restraint straps to extend or retract as needed, thereby optimizing the use of space around the nursing bed. This design allows the restraint equipment to fit snugly against the nursing bed without affecting the patient's movement space, improving the overall design's rationality.

[0042] Furthermore, the knob has anti-slip textured edges on its circumferential sidewalls.

[0043] The beneficial effects of the basic design are: 1. The anti-slip texture effectively increases the coefficient of friction on the knob surface, allowing medical staff to obtain a better grip and stability when rotating the knob. This helps prevent operational errors or safety hazards caused by slippery hands or an overly smooth knob surface.

[0044] 2. The anti-slip texture allows medical staff to more precisely control the rotation angle and force of the knob, thereby achieving fine adjustment of the restraint strap length. This design helps improve the accuracy and reliability of the operation, ensuring that the restraint equipment can meet the needs of different patients.

[0045] 3. The anti-slip texture typically provides a distinct tactile feel, allowing healthcare workers to quickly identify and accurately operate the knobs. This design facilitates rapid adjustment of restraints in emergency situations, improving emergency response speed. Attached Figure Description

Detailed Implementation

[0051] The following detailed description illustrates the specific implementation method:

[0052] Example 1

[0053] The basics are as follows: Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown: A psychiatric adjustable multifunctional protective restraint device includes a restraint strap 1 and a fixing strap 4. An adjustment component is installed on one side of the restraint strap 1, and the side of the adjustment component away from the restraint strap 1 is fixedly hooked to the fixing strap 4. The other end of the fixing strap 4 is hooked to a nursing bed through a length adjuster.

[0054] The adjustment assembly includes an adjustment kit 2 axially fixed to one side of the constraint band 1. A locking spring 14 is welded to the center of the outer surface of the adjustment kit 2. A knob 5 is slidably connected to the end of the locking spring 14 away from the adjustment kit 2. An axial toothed ring 15 is welded to the side of the knob 5 near the locking spring 14. An adjustment shaft 17 is engaged with the side of the axial toothed ring 15 near the adjustment kit 2. An axial toothed groove 16 is axially formed at the end of the adjustment shaft 17 near the knob 5. The axial toothed groove 16 engages with the axial toothed ring 15. The adjustment shaft 17 passes vertically through the adjustment kit 2 and the constraint band 1 and is rotatably connected to the inner walls of both sides of the adjustment kit 2 by pins. The adjustment shaft 17 located in the adjustment kit 2 is engaged with a toothed belt assembly. Several locking grooves facing the adjustment shaft 17 are formed inside the outer wall of the adjustment kit 2. Each locking groove has a sliding locking arc. The locking arc strip 13 is fixedly connected to a locking tooth 19 at one end near the adjusting shaft 17. The locking arc strip 13 is axially bonded to an arc spring 12 at the other end away from the locking tooth 19. The other end of the arc spring 12 is bonded to the inner wall of the corresponding locking groove. A sliding arc block 7 is welded to the side of the locking arc strip 13 near the knob 5. The outer edge of the knob 5 near the adjusting kit 2 is slidably engaged with the sliding arc block 7. The outer circumference of the adjusting shaft 17 has a circumferential tooth groove 18 corresponding to the locking tooth 19. The locking tooth 19 meshes with the circumferential tooth groove 18. Protective blocks 3 located on both sides of the knob 5 are welded to the outer wall of the adjusting kit 2. The protective blocks 3 are fixedly hung with the fixing strap 4. The inner and outer walls of the constraint strap 1 and the adjusting kit 2 are covered with a flexible layer 8. The circumferential side wall of the knob 5 has anti-slip texture 6, which can improve the rotation accuracy of the knob 5.

[0055] The specific implementation process is as follows: Traditional restraint belt 1 uses a belt buckle for locking, so it can only be adjusted in multiple tightnesses according to the position of the buckle. Moreover, when medical staff adjust it, they need to loosen the belt to lock it, which is not only complicated to operate, but also easy to cause the patient's limbs to break free, affecting the restraint effect and the patient's comfort.

[0056] like Figure 4 As shown, this device uses a knob 5 design. A suitable restraint strap 1 is selected and fitted onto the patient's limb. Then, the fixed strap 4 on the protective block 3 connects to the length adjuster on the nursing bed to restrain the patient's limb movement. The protective block 3 not only enhances the connection strength with the fixed strap 4 but also protects the knob 5 from accidental activation by the patient. Pressing the knob 5 compresses the locking spring 14, causing the knob 5 to descend and fully engage the inner axial toothed ring 15 with the axial toothed groove 16. Simultaneously, the outer edge of the knob 5 presses down on the sliding arc block 7, converting the downward force into a force that pushes the locking arc strip 13 axially away from the adjusting shaft 17. At this time, the locking arc strip 13 compresses the arc strip spring 12, causing the locking tooth 19 to disengage from the circumferential toothed groove 18 on the adjusting shaft 17, releasing the rotational lock on the adjusting shaft 17. Rotating the knob 5 then allows adjustment of the restraint strap 1's tightness to a suitable level through the toothed strap assembly engaged with the adjusting shaft 17, improving the comfort, safety, and convenience of the restraint device.

[0057] After adjusting to the appropriate tightness, the medical staff releases knob 5. Knob 5 is lifted by locking spring 14, causing axial toothed ring 15 to disengage from axial toothed groove 16. Locking arc strip 13, rebounded by arc strip spring 12, is pushed into the circumferential toothed groove 18 of adjusting shaft 17, thus firmly locking the tightness of restraint strap 1. At this point, rotation of knob 5 will not affect the locking of adjusting shaft 17. This is a second layer of protection against accidental activation added to knob 5 based on protective block 3, aiming to enhance the restraint effect and safety of the restraint device. The flexible layer 8 on restraint strap 1 and adjusting kit 2 prevents patients from struggling and injuring themselves during restraint. The anti-slip texture 6 on the side wall of knob 5 helps medical staff rotate knob 5 more easily and adjust the tightness of restraint strap 1 more precisely.

[0058] Example 2

[0059] The difference from the above embodiments is that, as shown in the appendix Figure 2 and Figure 4As shown: The gear belt assembly includes several gear disks 20 that are rotatably connected to the inner wall pins of the adjusting kit 2. Adjacent gear disks 20 mesh with each other, and the two gear disks 20 in the center of the adjusting kit 2 mesh with the adjusting shaft 17. A triangular shaft 21 is coaxially welded to one side of each gear disk 20. The outer diameter of the triangular shaft 21 is smaller than the outer diameter of the gear disk 20. The triangular shaft 21 passes through the constraint belt 1 and is rotatably connected to the inner wall pin on the other side of the adjusting kit 2. An annular cavity 9 is opened inside the constraint belt 1. Several adjusting belts 10 corresponding to the gear disks 20 are slidably fitted inside the annular cavity 9. Both ends of the adjusting belt 10 are bonded to the two sides of the corresponding triangular shaft 21. An axial connecting belt 11 is slidably fitted inside the side of the annular cavity 9 away from the adjusting kit 2. The connecting belt 11 is bonded to the adjusting belt 10.

[0060] The specific implementation process is as follows: When the medical staff rotates the knob 5, the adjusting shaft 17 rotates and drives the meshing gear disk 20 to rotate. The gear disk 20 then transmits the rotation to the adjacent gear disk 20. At the same time, the triangular shaft 21 on the gear disk 20 rotates synchronously to winch the adjusting belt 10, tightening or loosening the adjusting belt 10. The connecting belt 11 fixedly connected to the adjusting belt 10 not only connects all the adjusting belts 10, but also has a large area, which can well balance the pulling speed and force of each adjusting belt 10, and disperse the pressure of the adjusting belt 10 being tightened in the annular cavity 9. When the pressure is transmitted to the inside of the restraint belt 1, it will no longer cause discomfort to the patient's limbs.

[0061] like Figure 4 As shown, after being rotated to the appropriate tension, the adjusting belt 10 wound up by the triangular shaft 21 can be stored in the space between the outer diameter of the triangular shaft 21 and the gear disk 20, ensuring the smooth winding of the adjusting belt 10. At the same time, after the knob 5 is released and the adjusting shaft 17 is locked again, all gear disks 20 will be indirectly locked by the middle adjusting shaft 17, thereby fixing the constraint effect of the adjusting belt 10, and playing the role of adjusting and locking the tension of the constraint belt 1 at any time, enhancing the comfort and safety of the restraint device.
