Description

Technical Field

[0001] This utility model relates to the field of intensive care technology, specifically a restraint device. Background Technology

[0002] Intensive care refers to the intensive treatment and nursing care provided to critically ill patients using various advanced medical technologies and modern monitoring and resuscitation equipment, in order to maximize the patient's survival and subsequent quality of life. Intensive care restraint devices are used to restrain the limbs of critically ill patients to prevent them from moving around and affecting their treatment.

[0003] Some patients may struggle or resist during treatment, requiring temporary restraint. However, existing restraint devices are not easily adjustable to fit the patient's body size, which may cause greater discomfort and harm.

[0004] Therefore, those skilled in the art have provided a restraint device to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to provide a restraint device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A restraint device includes a main plate, a hand fixing mechanism, and a leg fixing mechanism. A pull-out plate is slidably connected to one end of the main plate. Multiple sets of support rods are fixedly connected to the bottom ends of both the main plate and the pull-out plate. Each support rod is equipped with a caster wheel at its bottom end. Arm fixing sleeves are slidably connected to both the left and right ends of the main plate. A hand fixing mechanism is provided at the upper end of the arm fixing sleeve. A leg fixing sleeve is fixedly connected to the upper end of the pull-out plate. A leg fixing mechanism is provided inside the leg fixing sleeve.

[0008] As a further embodiment of this utility model: a threaded rod is rotatably connected to one side wall of the main body plate, and a sliding rod is fixedly connected to the other side wall of the main body plate. A sliding sleeve is slidably connected to the outer side wall of the sliding rod. A threaded sleeve is threadedly connected to the outer side wall of the threaded rod. A movable plate is fixedly connected to the upper end of both the threaded sleeve and the sliding sleeve. A first connecting rod is fixedly connected to the bottom end of each movable plate. Two sets of first connecting rods are fixedly connected. A second connecting rod is fixedly connected to the upper end of each movable plate. The second connecting rods are fixedly connected to the arm fixing sleeve. A slot is opened on the inner side of each arm fixing sleeve. A T-shaped locking block is slidably connected in each slot. A connecting plate is fixedly connected to the upper end of each T-shaped locking block. A fixing elastic band is fixedly connected between the two sets of connecting plates.

[0009] As a further embodiment of this utility model: each of the arm fixing sleeves is rotatably connected to a driven gear, one end of which is rotatably connected to a driving gear, and a servo motor is fixedly connected to the upper end of the driving gear. Both the arm fixing sleeve and the driven gear are provided with fixing grooves. Multiple sets of arc-shaped grooves are provided on the outer wall of the driven gear. Each arc-shaped groove is slidably connected to a limit rod. The other end of each limit rod is hinged to a hinge rod, and the other end of each hinge rod is hinged to a fixing block. The fixing blocks abut against each other with adjacent fixing blocks.

[0010] As a further embodiment of this utility model: a bidirectional lead screw is rotatably connected inside the leg fixing sleeve, and movable sleeves are threaded to the outer walls of both the left and right ends of the bidirectional lead screw. A first fixing ring is fixedly connected to the upper end of each movable sleeve, and a second fixing ring is fixedly connected to both the left and right ends inside the leg fixing sleeve. A power motor is fixedly connected to one end of the bidirectional lead screw.

[0011] As a further improvement of this utility model, the driven gear and the driving gear are both meshed.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] Because it has a hand fixation mechanism, the screw rod rotates by shaking the rocker arm, which in turn moves the screw sleeve horizontally. This allows for precise adjustment of the arm fixation sleeve's position. The rotation of the limiting rod within the arc-shaped groove and the action of the hinge rod ensure that multiple fixation blocks can evenly and uniformly clamp the patient's arm. It can be adjusted according to different patient body shapes and needs. Through the slots and elastic bands within the fixation sleeve, it can provide maximum comfort while ensuring fixation effectiveness. Because it has a leg fixation mechanism, the precise control of the bidirectional screw allows the first fixation ring to move precisely to the second fixation ring, thereby achieving precise fixation of the patient's legs and avoiding errors or unnecessary adjustments. The position of the fixation rings can be flexibly adjusted according to different patient leg sizes and treatment needs, thus meeting the requirements of different treatment plans and exhibiting good adaptability.
