Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically, to a dual adjustable restraint strap. Background Technology

[0002] In clinical medicine, to prevent patients with impaired consciousness, such as those still under anesthesia, incoherent, or comatose, from falling out of bed, pulling out tubes, scratching, or bumping themselves due to agitation, restraint straps are often used for protective restraint with the consent of the patient's family. Traditional restraint straps are generally rectangular straps with four straps on opposite sides. When using them, the straps are used to wrap around the patient's limbs before securing them, or the patient's limbs are directly tied to the bed edge or other fixed supports. Existing restraint structures generally use Velcro for fixation, or Velcro combined with magnetic fasteners for secondary fixation. However, using Velcro directly results in insufficient tightness, and when using magnetic fasteners for secondary fixation, the magnetic fasteners need to be used with metal fasteners. This poses a significant risk to the patient, and metal fasteners are generally thin and prone to deformation during use, rendering them unusable. Furthermore, the adjustable range of metal fasteners is limited, and during restraint, the patient's struggle can cause the fasteners to slide in one direction, resulting in excessive tightness and increasing the risk of fractures or blood flow obstruction. Utility Model Content

[0003] This utility model discloses a dual adjustable constraint strap, which aims to solve the problems mentioned above.

[0004] The present invention adopts the following solution: This application provides a dual adjustable restraint strap, including a strap connector. Both ends of the strap connector are respectively provided with strap structures suitable for tightening on a user's limb. The strap structure includes a strip-shaped body. One side of the strip-shaped body is provided with a barbed hook and loop fastener segment and a rough hook and loop fastener segment. The rough hook and loop fastener segment is adapted to pass through an annular buckle provided on the strap connector so that the strip-shaped body forms a strap space suitable for being fitted on the user's limb. The rough hook and loop fastener segment is adapted to connect with the barbed hook and loop fastener after passing through the annular buckle so as to tighten the user's limb within the strap space. The strip-shaped body is provided with an outwardly extending cable tie structure, one end of which is fixed within the strip-shaped body, and the other end extends out of the strip-shaped body. The main body of the cable tie is provided with a locking structure, which forms a channel for the cable tie to pass through. An elastic buckle is provided within the channel, which is adapted to cooperate with a hook tooth structure provided on the cable tie to restrict the cable tie structure within the locking structure. Furthermore, by driving the elastic buckle, the locking of the hook tooth structure can be released, so as to adjust the tightness of the cable tie structure.

[0005] Furthermore, one side of the main body of the strap is provided with a foldable cover structure, which is adapted to cover the strap structure and the buckle structure when the strap structure is fixed in the buckle structure.

[0006] Furthermore, the cover structure is foldably attached to the strap connector via a Velcro structure.

[0007] Furthermore, each strap structure has two sets of cable tie structures arranged in parallel, and each end of the strap connector has two locking structures that match the cable tie structure.

[0008] Furthermore, the cable tie structure is detachably mounted on the strap structure.

[0009] Furthermore, the locking structure includes a locking body fixed to the strap connector, the locking body having a channel formed therein suitable for the cable tie structure to pass through; an elastic buckle and a movable through groove suitable for the movement of the elastic buckle are provided on the side of the locking body away from the strap connector; the side of the elastic buckle facing the channel has movable hooks suitable for locking the hook tooth structure on the cable tie structure to restrict the movement of the cable tie structure in the direction of loosening; pressing the elastic buckle allows the movable hooks to disengage from the hook tooth mechanism so that the cable tie structure is suitable for movement in the direction of loosening.

[0010] Furthermore, the end of the elastic buckle is provided with a limiting part, which is adapted to be engaged with the top surface of the locking body to prevent the elastic buckle from falling into the movable through groove in the locked state; an avoidance groove is formed on one side of the limiting part on the locking body, and by driving the limiting part of the elastic buckle to move toward one side of the avoidance groove, the limiting part is adapted to be pressed into the avoidance groove so as to unlock the cable tie structure.

[0011] Beneficial effects: This solution utilizes both barbed and hook-and-loop fasteners on the binding structure to create a first layer of tightening, achieving initial limb locking. After this initial locking, a second layer of locking is achieved through the binding structure to ensure complete limb restraint and prevent escape. The binding structure avoids damage to existing binding structures caused by excessive patient force, facilitates precise size adjustment, and offers a longer adjustment range to accommodate patients of different body types. It also eliminates the use of metal restraint structures, preventing deformation and potential accidents. Furthermore, elastic buckles lock the binding structure, facilitating easy unlocking and adjustment. A limiting element prevents accidental activation of the elastic buckles and loosening of the binding structure while locked. A cover structure conceals the binding and locking structures, preventing loosening due to pressure from the person being bound. Compared to existing technologies, this structure is lower in cost, simpler and more convenient to use, and offers higher safety. Attached Figure Description

Detailed Implementation

[0013] Combination Figures 1 to 7As shown, this embodiment provides a dual adjustable restraint strap, including a strap connector 1. Both ends of the strap connector 1 are respectively provided with strap structures 2 suitable for tightening onto a user's limb. The strap structure 2 includes a strip 21, one side of which is provided with a barbed hook and loop fastener segment 22 and a rough hook and loop fastener segment 23. The rough hook and loop fastener segment 23 is adapted to pass through an annular buckle 24 provided on the strap connector 1 so that the strip 21 forms a strap space suitable for fitting onto the user's limb. Furthermore, the rough hook and loop fastener segment 23 is adapted to connect with the barbed hook and loop fastener after passing through the annular buckle 24, thereby tightening the user's limb. Within the binding space; a cable tie structure 3 is provided within the strip 21, suitable for extending outwards. One end of the cable tie structure 3 is fixed within the strip 21, and the other end extends out of the strip 21. A locking structure 4 is provided on the main body of the binding tie, and the locking structure 4 forms a channel 45 through which the cable tie passes. An elastic buckle 42 is provided within the channel 45, and the elastic buckle 42 is adapted to cooperate with the hook tooth structure 31 provided on the cable tie to restrict the cable tie structure 3 within the locking structure 4. Moreover, by driving the elastic buckle 42, the locking of the hook tooth structure can be released, so as to adjust the tightness of the cable tie structure 3.

[0014] Combination Figures 1 to 4 As shown, in this embodiment, the strap connector 1 can be made of existing fabric or fiber fabric to ensure connection strength. The strip 21 has a multi-layer structure; specifically, its interior can be a high-strength fabric, such as existing nylon webbing, that is fixedly connected to the strap connector 1. The first side of the strip 21 is provided with a barbed hook and loop fastener section 22 and a loose hook and loop fastener section 23, the length of which can be set in various specifications to form different sizes of strapping spaces. The second side of the strip 21 is provided with a flexible pad to improve comfort when in contact with the user's limb. The ring buckle 24 is fixed to the strap connector 1 for the strip 21 to pass through, and after the strip 21 passes through, it is pulled back to make the loose hook and loop fastener suitable for cooperation with the barbed hook and loop fastener, and to form a strapping space that is fitted over the outside of the user's limb.

[0015] Combination Figures 4 to 7 As shown, the cable tie structure 3 can be a nylon cable tie with movable hooks 43. One end of the cable tie structure 3 can be fixed to the strip body 21, and the other end extends out of the strip body 21 and can be inserted into the locking structure 4 provided on the strap connector 1 to achieve a second locking. Here, the cable tie structure 3 can be fixed to the strip body 21 by weaving, or it can be detachably connected to the strip body 21 by existing locking methods to facilitate the replacement of the cable tie structure 3.

[0016] The solution in this embodiment can achieve a double locking effect of the strap structure 2, while also being easy to adjust; and since the strap structure 3 requires the user to pull it from the outside to lock it, it can avoid the problem of the strap becoming tighter due to excessive force exerted by the user, and the avoidance of using metal components can improve safety.

[0017] Combination Figure 4 As shown, in a preferred embodiment, a foldable cover structure 48 is provided on one side of the main body of the strap. The cover structure 48 is adapted to cover the cable tie structure 3 and the locking structure 4 when the cable tie structure 3 is fixed inside the locking structure 4. Here, the cover structure 48 can be foldably connected to the strap connector 1 via a Velcro structure. Specifically, one side of the cover structure 48 can be fixed to one side of the strap connector 1, and the other side is provided with a Velcro loop surface for engaging with the Velcro barbed surface provided on the strap connector 1. When adjustment or tightening is required, the cover structure 48 is flipped open to expose the cable tie structure 3 and the locking structure 4 for easy user operation; after operation, the cover structure 48 is folded back to connect the Velcro loop surface with the Velcro barbed surface, covering the locking structure 4 and the cable tie structure 3, effectively preventing the exposed locking structure from being touched by the person being strapped, thus improving safety.

[0018] In this embodiment, two sets of cable tie structures 3 are arranged in parallel on each strap structure 2, and two locking structures 4 matching the cable tie structures 3 are provided on the strap connector 1 at each end. The two cable tie structures 3 can make the force evenly distributed and prevent the adverse effects of localized force.

[0019] Combination Figures 4 to 7 As shown, in a preferred embodiment, the locking structure 4 includes a locking body 41 fixed to the strap connector 1, with a channel 45 formed within the locking body 41 suitable for the cable tie structure 3 to pass through. An elastic buckle 42 and a movable through groove 44 suitable for the elastic buckle 42 are provided on the side of the locking body 41 away from the strap connector 1. A movable hook 43 is provided on the side of the elastic buckle 42 facing the channel 45, suitable for engaging the hook tooth structure 31 on the cable tie structure 3 to restrict the cable tie structure 3 from moving in the direction of loosening. Pressing the elastic buckle 42 allows the movable hook 43 to disengage from the hook tooth structure 31, thus allowing the cable tie structure 3 to move in the direction of loosening. By pressing the elastic buckle 42, the movable hook 43 can be disengaged inward from the hook tooth structure 31, thereby releasing the locking of the cable tie structure 3. It should be noted that the elastic buckle 42 mentioned here refers to the movable buckle part provided on the locking body 41, which moves within the movable through groove 44 by operating the elastic buckle part.

[0020] Combination Figure 7 As shown, in a preferred embodiment, a limiting part 46 is provided at the end of the elastic buckle 42. The limiting part 46 is adapted to engage with the top surface of the locking body 41 to prevent the elastic buckle 42 from falling into the movable through groove 44 in the locked state. A relief groove 47 is formed on one side of the limiting part 46 on the locking body 41. By driving the limiting part 46 of the elastic buckle 42 to move toward the relief groove 47, the limiting part 46 is adapted to be pressed into the relief groove 47 to unlock the cable tie structure 3. The limiting part 46 prevents the elastic buckle 42 from being pressed into the movable through groove 44 in the locked state. By providing the relief groove 47, the limiting part 46 can only sink into the relief groove 47 after the user drives the elastic buckle 42 to shift laterally by a certain distance, so that the elastic buckle 42 swings and releases the restriction on the cable tie structure 3. It should be noted that the elastic buckle 42 described here can be made of materials such as plastic or nylon, which have high strength and can only move a small distance laterally. Specifically, a recess can be provided at the connection between the elastic buckle 42 and the locking body 41 to allow the elastic buckle 42 to shift laterally at a certain angle. In addition, it should be noted that when the elastic buckle 42 is pressed, the limiting part 4646 remains within the clearance groove 47 to prevent it from entering the channel 45 and affecting the movement of the cable tie structure 3.

[0021] This embodiment achieves initial locking of the limb by forming a first-layer binding structure with barbed hook and loop fastener sections 22 and rough hook and loop fastener sections 23 on the binding structure 2. After initial locking, a second layer of locking is achieved through the cable tie structure 3 to ensure the limb is locked and prevent escape. The cable tie structure 3 avoids damage to the existing cable tie structure 3 caused by excessive force from the patient, facilitates precise size adjustment, and has a longer adjustment range to accommodate patients of different body types. It also eliminates the need for metal binding structures, avoiding deformation and potential accidents. Furthermore, the cable tie structure 3 is locked by an elastic buckle 42, facilitating unlocking and adjustment. A limiting part 46 prevents accidental activation of the elastic buckle 42 and loosening of the cable tie structure 3 while it is locked. A cover structure 48 covers the cable tie structure 3 and the locking structure 4, preventing the bound person from pressing and loosening it. Compared to existing technologies, this structure is lower in cost, simpler and more convenient to use, and more secure.
