The invention discloses a knee joint injection patient body position placing device, and relates to the technical field of medical instruments, the knee joint injection patient body position placing device comprises a supporting plate, a lifting assembly is arranged on one side of the top surface of the supporting plate, the lifting assembly comprises a first lead screw, two lower supporting plates and two upper supporting plates, the first lead screw is rotatably arranged above the supporting plate, and the lower supporting plates and the upper supporting plates are rotatably arranged on the supporting plate; the two lower supporting plates are fixedly connected to the top face of the supporting plate, the two upper supporting plates are fixedly connected to the two ends of the bottom face of the bearing platform plate, the lower supporting plates and the upper supporting plates are arranged in an up-down corresponding mode, and a moving assembly is arranged on the supporting plate. The knee joint injection patient body position placing device has the advantages that a medical worker does not need to manually lift the legs of a patient and keep the thighs and the shanks at a certain bending angle, the operation difficulty is lowered, the knee joint injection efficiency is improved, the body position of the legs of the patient is limited, and the patient can conveniently and rapidly place the body position. The body position change of the patient due to pain during injection is avoided, and the technical effect of knee joint injection effect is ensured.

This utility model provides a bending test device for heated seat cushions, belonging to the field of testing tooling technology. It includes: a frame with a roller and a movable sliding seat; a linear drive element mounted on the frame and connected to the sliding seat; a tensioning element with a second connecting part for connecting to the other end of the heated seat cushion; a straight line A passing through the sliding seat and tangent to the roller and a straight line B passing through the tensioning element and tangent to the roller are not collinear; the sliding seat moves along straight line A, and the tensioning element moves along straight line B. The advantages of this utility model are: it provides a device capable of automatically testing the bending of heated seat cushions; the sliding seat and tensioning element can pull the heated seat cushion back and forth relative to the roller, thereby causing the heated seat cushion to be repeatedly squeezed by the roller to simulate a bending effect, achieving full automation and improving testing efficiency.
