Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular relates to a lower limb restraint belt assembly and a restraint bed. Background Art

[0002] A restraint belt is a tool used to restrict the patient's body or limb movements to prevent the patient from hurting himself or others. For example, the patent number CN215192752U is an adjustable restraint belt, and the content of the patent is "including a belt, a sponge belt is connected to the outside of the belt, and tightening devices for tightening the belt are connected to both sides of the belt, and a roller device for facilitating the tightening of the belt is connected to the top of the tightening device, and a fixing device for installation and fixing is connected to the bottom of the tightening device..."

[0021] The nouns, conjunctions or adjectives involved in the above technical solution are explained as follows:

[0022] Fixed connection refers to a connection in which parts or components are fixed without any relative movement. There are two types of connection: detachable and non-detachable.

[0023] (1) A removable connection is a connection that uses screws, splines, wedge pins, etc. to hold parts together. This type of connection can be disassembled for maintenance without damaging the parts. However, the specifications of the connectors used must be correct (such as the length of the bolts, keys, and wedge pins) and they must be properly tightened.

[0024] (2) Non-detachable connections mainly refer to welding, riveting and tenoning. Since they need to be disassembled by forging, sawing or oxygen cutting for maintenance or replacement, spare parts generally cannot be reused. At the same time, when making connections, attention should be paid to process quality, technical inspection and remedial measures (such as calibration, polishing, etc.).

[0025] A threaded connection refers to a detachable connection in which the connected parts are connected together using threaded parts (or the threaded parts of the connected parts).

[0026] A sliding connection is when two objects are in contact but not fixed and can slide relative to each other.

[0027] A rotational connection is a connection between parts that allows the parts to rotate relative to each other.

[0028] Beneficial effects of the present invention:

[0029] The medical staff inserts the patient's lower limbs into the restraint belt. First, the second bidirectional screw is rotated to drive the two second drive plates to move in opposite directions, the second drive plate drives the connecting plate to move, the connecting plate drives the rotating shaft to move, the two rotating shafts move in opposite directions, the distance increases, and the restraint belt is pulled to both ends to tighten the restraint belt. Next, the first bidirectional screw is rotated to drive the two first drive plates to move toward each other, the first drive plate drives the connecting rod to move, the connecting rod drives the restraint member to move, and the two restraint members approach each other until they are in close contact with the patient's lower limbs. Through the restraint of the restraint member, the space on the side of the limb is squeezed and reduced by the restraint member, so that the patient's limb is subject to sufficient restraint force.
