Description

Technical Field

[0001] This utility model relates to the field of human necessities, especially to the field of medical assistive devices, and in particular to a limb restraint device with a loosening alarm function. Background Technology

[0002] In clinical practice, NICU patients are often unconscious, restless, or still recovering from postoperative anesthesia or sedation. To ensure the safety of both the patient and the catheter, protective restraints are necessary. Protective restraints involve using physical or mechanical devices, materials, or tools attached to or near the patient's body to restrict their free movement. These restraints should not be easily removed by the patient or prevent them from accessing their own body normally. Protective restraints play a crucial role in ensuring patient safety and the smooth progress of treatment and nursing care.

[0003] In the existing technology, limb restraint devices are usually used to protect patients. These devices are mostly cylindrical structures that restrain patients by surrounding their limbs. They also usually have adjustable tightness restraint straps to accommodate people of different body types and needs.

[0004] However, existing limb restraint devices still have the following drawbacks:

[0005] 1. Most existing restraint devices are cylindrical in shape. Patients may rotate their arms and roll along with the restraint device, causing displacement. Continuous displacement will accelerate the loosening of the restraint straps, causing them to come loose and leading to restraint failure.

[0006] 2. If the adjustable restraint straps become loose, the restraints will not be secure, allowing the patient to break free. Once freed, there will be no warning or alarm, making it difficult for medical staff to detect, which may lead to serious unplanned extubation accidents. Utility Model Content

[0007] The purpose of this utility model is to provide a limb restraint device with a loosening alarm function. The limb restraint device with a loosening alarm function aims to solve the technical problem in the prior art where patients roll their arms and the restraint device together, accelerating the loosening of the restraint straps, and the loosening of the restraint straps is difficult for medical staff to detect.

[0008] A limb restraint device with a loose strap alarm function includes a first restraint plate, a second restraint plate, and a third restraint plate. The right side of the first restraint plate is hinged to the left side of the second restraint plate, the right side of the second restraint plate is hinged to the left side of the third restraint plate, and the right side of the third restraint plate is close to the other left side of the first restraint plate. The first, second, and third restraint plates form a hollow triangular prism structure. The device includes a restraint strap that passes sequentially over the outer surfaces of the first, second, and third restraint plates and is then connected end-to-end by a locking device. A loose strap detection device is provided on one of the first, second, or third restraint plates. The loose strap detection device includes a housing, with openings on both sides of the housing. A first strip-shaped through hole and a second strip-shaped through hole; a first limiting block is provided on the left side of the inner cavity of the housing, a second limiting block is provided on the right side of the inner cavity of the housing, a contact switch is provided on the left side of the second limiting block, the trigger end of the contact switch abuts against the right side of the first limiting block, and the first limiting block and the second limiting block are connected to each other by a spring; the constraint belt includes a front belt body and a rear belt body, the right end of the front belt body passes through the first strip-shaped through hole and is fixed to the left side of the first limiting block, and the left end of the rear belt body passes through the second strip-shaped through hole and is fixed to the right side of the second limiting block; a buzzer, a main switch and a power supply are also provided on the same constraint plate as the loose belt detection device, and the contact switch, buzzer, main switch and power supply are connected in series.

[0009] Furthermore, the device includes two or more restraint straps, the number of strap slack detection devices being the same as the number of restraint straps, each restraint strap being connected to one strap slack detection device, and all the contact switches being connected in parallel.

[0010] Furthermore, the front section of the belt is provided with a length adjustment buckle, and the length adjustment buckle is provided with a locking nut, the bottom end of which abuts against the front section of the belt.

[0011] Compared with existing technologies, the advantages of this invention are positive and obvious:

[0012] 1. The first restraint plate, the second restraint plate and the third restraint plate of this utility model form a hollow triangular prism structure, which prevents the patient from rotating their arm and rolling over with the restraint device, thus improving stability and slowing down the loosening speed of the restraint strap.

[0013] 2. The loose strap detection device of this utility model can detect whether the restraint strap is loose, and at the same time alert medical staff through a buzzer to avoid consequences such as unplanned extubation after the patient breaks free. Attached Figure Description

[0020] The following embodiments will further illustrate the present invention, but are not intended to limit the present invention.

[0021] like Figures 1 to 5 As shown, this embodiment provides a limb restraint device with a loosening alarm function. The device consists of three restraint plates: a first restraint plate 1, a second restraint plate 2, and a third restraint plate 3. The right side of the first restraint plate 1 is hinged to the left side of the second restraint plate 2, the right side of the second restraint plate 2 is hinged to the left side of the third restraint plate 3, and the right side of the third restraint plate 3 is close to the other left side of the first restraint plate 1. This allows the first restraint plate 1, the second restraint plate 2, and the third restraint plate 3 to form a hollow triangular prism structure. The three restraint plates are the three sides of the triangular prism. By wrapping the patient's limb within the triangular prism structure, the three restraint plates contact the limb from three angles to achieve the restraint effect. Memory foam pads are installed on the side of each restraint plate closest to the patient, increasing the contact area with the patient's limb, improving comfort, and preventing pressure sores. The triangular prism provides stability, preventing the restraint device from rolling and displacing when the patient rotates their arm, thus improving stability and slowing the loosening speed of the restraint straps 4.

[0022] It includes two constraint straps 4, which are distributed at intervals along the length of the constraint plate. Each constraint strap 4 passes through the outer side of the first constraint plate 1, the second constraint plate 2 and the third constraint plate 3 in sequence and is connected end to end by a locking device 5. The locking device 5 is a known technology and includes a male buckle 502 and a female buckle 501. The male buckle 502 and the female buckle 501 are inserted into each other to achieve locking.

[0023] Two loose strap detection devices 6 are fixed on the first constraint plate 1, corresponding to the two constraint straps 4 respectively. Each constraint strap 4 is connected to one of the aforementioned loose strap detection devices 6. The loose strap detection devices 6 are used for loose strap detection, and at the same time, they also serve to fix the constraint straps 4 to the first constraint plate 1.

[0024] Any loose belt detection device 6 includes a housing 601, with a first strip-shaped through hole 606 and a second strip-shaped through hole 607 respectively opened on both sides of the housing 601; a first limiting block 602 is provided on the left side of the inner cavity of the housing 601, a second limiting block 603 is provided on the right side of the inner cavity of the housing 601, and a contact switch 605 is provided on the left side of the second limiting block 603.

[0025] The first limiting block 602 and the second limiting block 603 are connected to each other by a spring 604. The spring 604 biases the right side of the first limiting block 602 toward the left side of the second limiting block 603. In the free state of the spring 604, the trigger end of the contact switch 605 abuts against the right side of the first limiting block 602 to trigger the switch. When the first limiting block 602 and the second limiting block 603 move away from each other, the spring 604 is stretched, the first limiting block 602 no longer abuts against the contact switch 605, and the contact switch 605 is disconnected.

[0026] The restraint belt 4 includes a front belt body 401 and a rear belt body 402; the left end of the front belt body is fixedly connected to the male buckle 502, and the right end of the front belt body 401 passes through the first strip-shaped through hole 606 and is fixedly connected to the left side of the first limiting block 602; the right end of the rear belt body is fixedly connected to the female buckle 501, and the left end of the rear belt body 402 passes through the second strip-shaped through hole 607 and is fixedly connected to the right side of the second limiting block 603.

[0027] When the constraint band 4 is taut, the front section of the band 401 pulls the first limiting block 602 to the left, and the rear section of the band pulls the second limiting block 603 to the right, so that the first limiting block 602 and the second limiting block 603 abut against the two sides of the inner cavity of the housing 601 respectively, and the contact switch 605 is triggered to disconnect; when the constraint band 4 is slack, the first limiting block 602 and the second limiting block 603 approach each other under the action of the spring 604, triggering the contact switch 605.

[0028] On the same restraint plate as the loose strap detection device 6, there is also a buzzer 7, a main switch 8, and a power supply 9. Two parallel contact switches 605, the buzzer 7, the main switch 8, and the power supply 9 are connected in series. The two contact switches 605 are connected in parallel within the aforementioned series circuit. The main switch 8 controls whether the loose strap alarm function is activated. When the main switch 8 is activated, triggering either contact switch 605 will connect the circuit, thereby activating the buzzer 7 to sound an alarm, reminding medical personnel that the restraint of the restraint strap 4 has loosened. The connecting wires of the above electrical components are all embedded in the first restraint plate 1 to avoid exposed wires.

[0029] In this embodiment, the power source 9 is a lithium battery module with a charging module. In other embodiments, it can also be replaced by a dry cell battery or other power source 9. The charging port is located on the top surface of the first constraint plate 1 for easy use.

[0030] A length adjustment buckle 503 is installed on the front section 401 of any restraint strap 4. The length adjustment buckle 503 is a known technology and is similar to the length adjustment buckle 503 on a backpack. The length is adjusted by rewinding the restraint strap 4. In this embodiment, a locking nut 504 is threaded onto the length adjustment buckle 503. After tightening the locking nut 504, the bottom end of the locking nut 504 abuts against the front section 401, thereby facilitating the adjustment of the length of the restraint strap 4 while preventing the restraint strap 4 at the length adjustment buckle 503 from loosening and slowing down the loosening speed of the restraint strap 4.

[0031] How to use this embodiment:

[0032] The first restraint plate 1, the second restraint plate 2, and the third restraint plate 3 are wrapped around the patient's limb. By wrapping the patient's limb in a triangular prism structure, the three restraint plates abut against the limb from three angles to achieve the restraint effect.

[0033] Then, the two restraint straps 4 are connected end to end by the locking device 5, and the length of the restraint straps 4 is adjusted by the length adjustment buckle 503, so that the restraint straps 4 are tightened.

[0034] Turn on the main switch 8 to activate the belt loosening alarm function.

[0035] When the restraint band 4 is tightened, the first limit block 602 and the second limit block 603 in the slack band detection device 6 move away from each other, and the contact switch 605 is triggered to disconnect; when the restraint band 4 is loosened, the first limit block 602 and the second limit block 603 move closer together under the action of the spring 604, triggering the contact switch 605.

[0036] Triggering any contact switch 605 will connect the circuit, thereby activating the buzzer 7 to sound an alarm, reminding medical staff that the restraints on the restraint belt 4 have loosened.

[0037] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
