[0024] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0025] Please refer to Figure 1-Figure 8 The patient anti-slip restraint mechanism comprises: a gantry 1, two hoops 2 are fixedly installed at the bottom of the gantry 1, which is convenient for installing the device on the bed, and a frame 3 is provided in the gantry 1, a bidirectional screw 4 is rotatably installed in the frame 3, two linkage seats 5 are threadedly installed on the bidirectional screw 4, and two support rods 1 are fixed in the frame 3, both of which penetrate the linkage seat 5 and are slidably connected thereto, a limited opening is provided at the bottom of the frame 3, the bottoms of the two linkage seats 5 are both passed through the limited opening and contact with the inner wall of the limited opening, thereby limiting the linkage seat 5 so that it can only move linearly horizontally, and a connecting piece 6 is fixedly installed at the bottom of the two linkage seats 5, and the two connecting pieces 6 are fixedly installed at the bottom of the two linkage seats 5. The top of the connecting piece 6 is in contact with the bottom of the frame 3, and the bottom of the two connecting pieces 6 is fixedly installed with a cylinder 7, and the two cylinders 7 are slidably installed with a restraint rod 8, and the bottom ends of the two restraint rods 8 extend to the bottom of the two cylinders 7 respectively. In addition, a rubber sleeve 9 is fixedly sleeved on the two restraint rods 8, which can form soft protection for the patient's armpits, and a top screw 10 is threadedly installed on the two cylinders 7, and the ends of the two top screws 10 are in conflict with the corresponding restraint rods 8, so that the restraint rod 8 can be fixed to prevent it from loosening, and a position adjustment mechanism is provided on the gantry 1, which is used to adjust the spatial position of the restraint rod 8 so that it can be stuck in the patient's armpit.

[0026] In the above-mentioned manner, the position adjustment mechanism provided includes an internal threaded sleeve 11, which is rotatably mounted on the top of the gantry 1, and the internal threaded sleeve 11 is internally threaded with a lifting screw 12, and the bottom end of the lifting screw 12 is fixedly mounted with a U-shaped frame 13, and a limit rod is slidably mounted on the gantry 1, and the bottom end of the limit rod is fixed to the U-shaped frame 13, thereby indirectly providing a limit to the lifting screw 12 so that it cannot rotate, and at the top of the gantry 1 A motor is fixedly installed, and its output shaft and the internal threaded sleeve 11 are fixedly sleeved with bevel teeth, and the two bevel teeth are meshed with each other. Through the operation of the motor, the internal threaded sleeve 11 can be driven to rotate, and a longitudinal screw 14 is rotatably installed in the U-shaped frame 13, and a sliding plate 15 is threadedly installed on the longitudinal screw 14. The bottom of the sliding plate 15 is fixedly connected to the frame 3, and two support rods 2 are fixed in the U-shaped frame 13, and the two support rods 2 both penetrate the sliding plate 15 and are slidably connected thereto.

[0027] In this embodiment, in order to ensure the stability of the longitudinal horizontal movement of the frame 3, horizontal platforms 16 are fixedly installed on both sides of the U-shaped frame 13, and slide rails 17 are fixedly installed at the bottom of the two horizontal platforms 16. Slide blocks 18 are slidably installed on the two slide rails 17, and the bottoms of the two slide blocks 18 are fixedly connected to the frame 3.

[0028] In this method, in order to ensure that the restraint rod 8 slides up and down stably, two sliding openings are opened on the cylinder 7, and sliding rods are slidably installed in the two sliding openings. The ends of the two sliding rods close to each other are fixedly connected to the corresponding restraint rod 8.

[0029] The working principle of the patient anti-slip restraint mechanism provided by the utility model is as follows:

[0030] When the patient needs to be adjusted to a semi-recumbent position, first adjust the angle of the upper part of the bed, slowly lift the patient's upper body, and finally put it in a semi-recumbent position, then fix the gantry 1 to the guardrails on both sides of the bed through two clamps 2, and the installation position can be adjusted according to the position of the patient's upper body. After installation, first twist the two top screws 10 to separate the top screws 10 from the restraint rods 8;

[0031] Then, the motor is started in the forward direction, and the meshing of the two bevel teeth can drive the internal threaded sleeve 11 to rotate, and the lifting screw 12 brings the U-shaped frame 13 and the frame body 3 down together, until the restraint rod 8 contacts the inclined bed body and then the motor is turned off. At this time, the patient's upper body is between the two restraint rods 8, and the restraint rod 8 does not contact the patient's armpits on both sides. Then, the spacing between the two restraint rods 8 is adjusted according to the width of the patient's upper body. When adjusting, the two-way screw 4 is directly rotated, and the two linkage seats 5 move in the direction of approaching each other until the two restraint rods 8 contact the two sides of the patient's upper body respectively. Then, the longitudinal screw 1 is rotated. 4, the sliding plate 15 will move the frame 3 horizontally and longitudinally, and the two restraint rods 8 will follow it and move horizontally, and the restraint rods 8 will gradually approach the patient's armpits. At the same time, the restraint rods 8 are active at this time. When they rise along the tilt angle of the bed, the restraint rods 8 will retract into the cylinder 7 until the two restraint rods 8 are stuck in the armpits on both sides of the patient. Then, the rotation of the longitudinal lead screw 14 is stopped, and the two top screws 10 are tightened to fix the restraint rods 8. At this time, the two restraint rods 8 are firmly stuck in the armpits on both sides of the patient, thereby completing the restraint, and then the patient can be fed with medicine and other nursing work.

[0032] Compared with the related art, the patient anti-slip restraint mechanism provided by the utility model has the following beneficial effects:

[0033] The utility model provides a patient anti-slip restraint mechanism, which can clamp the two restraint rods 8 under the patient's armpits through various adjustment methods such as rotating the bidirectional screw 4, thereby forming an anti-slip restraint, and the anti-slip effect is reliable. Compared with traditional manual support, this method can bring convenience to nursing work to a greater extent, and the setting of the adjustment mechanism can be suitable for anti-slip restraint work for patients of different body shapes, and has good applicability.
