[0033] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6In one or more embodiments, a head placement piece for a prone position is provided, including a base 100 and a bottom plate 101. The top of the base 100 is hinged to the bottom left side of the bottom plate 101. A slide groove 102 and a limit groove 103 are symmetrically opened inside the base 100 with a horizontal center line of the base 100. The slide groove 102 and the limit groove 103 are connected to each other. A slider 104 is arranged inside the slide groove 102. A fixed column 105 is arranged on the surface of the slider 104. The other end of the fixed column 105 passes through the limit groove 103 and extends to the outside of the base 100. A connecting rod 106 is movably connected to the surface of the fixed column 105 and is located outside the base 100. The other end of the connecting rod 106 is connected to the The surface of the bottom plate 101 is movably connected, and a threaded rod 107 is movably connected to one side of the inner wall of one of the slide grooves 102, and the slider 104 is threadedly connected to the surface of the threaded rod 107, and the other end of the threaded rod 107 extends to the outside of the base 100. A facial perforation 108 is opened inside the bottom plate 101, and a soft pad 109 is provided on the top of the bottom plate 101. An elastic band 119 is provided on the inner wall of the facial perforation 108. The other end of the threaded rod 107 extends to the outside of the base 100 and is connected to a rotating plate 121. A fixed pad 122 is provided on the surface of the base 100, and the surface of the fixed pad 122 is in contact with the surface of the rotating plate 121. The material of the soft pad 109 is polymer gel.

[0034] In this embodiment, according to the actual situation of the patient, the threaded rod 107 can be driven to rotate by the rotating plate 121. Since the threaded rod 107 is limited to rotation and cannot change its position, the slider 104 is displaced on the surface of the threaded rod 107, and the fixed column 105 is displaced along with the slider 104. When it is rotated to an appropriate position, the position of the rotating plate 121 can be fixed by the squeezing action of the fixed pad 122. In this process, the position and deflection angle of the connecting rod 106 are changed, thereby changing the deflection angle of the bottom plate 101, and then the position of the cushion 109 can be adjusted according to the individual differences of the patient; the patient's face will be placed at the facial perforation 108, and the cushion 109 will contact the patient, and the elastic band 119 can contact the patient's forehead to ensure the stability of the patient's head position; the material of the cushion 109 includes but is not limited to the above-mentioned materials.

[0036] In this embodiment, the facial perforation 108 corresponds to the mirror 112, and the deflection angle of the mirror 112 can be changed by the universal joint 111, thereby cooperating with the angle deflection of the base plate 101, and then reflecting the patient's face, so that medical staff can check the facial condition of the patient in the prone position.

[0037] See also Figure 1 , Figure 2 and Figure 3 In some embodiments, a U-shaped frame 113 is provided on the left side of the base 100, and a lifting rod 114 is connected to the internal thread of the U-shaped frame 113. An extrusion plate 115 is provided at one end of the lifting rod 114 and is located in the restricted area of ​​the U-shaped frame 113. The other end of the lifting rod 114 extends to the outside of the U-shaped frame 113, and an anti-slip pad 120 is provided at the bottom of the extrusion plate 115.

[0038] In this embodiment, the U-shaped frame 113 can be placed on the bed board, and then the lifting rod 114 can be rotated. Since the lifting rod 114 and the U-shaped frame 113 are connected by threads, the extrusion plate 115 can drive the anti-skid pad 120 to move until the anti-skid pad 120 contacts the bed board, and the bed board is squeezed by the anti-skid pad 120 to be fixed. At the same time, the extrusion plate 115 and the anti-skid pad 120 can be fixed by means of the self-locking effect of the thread.

[0039] See also Figure 4 and Figure 5 In some embodiments, a tracheal tube channel 116 is opened inside the base 100, and the number of the tracheal tube channel 116 is multiple.

[0040] In this embodiment, the endotracheal tube can be passed through the endotracheal tube channel 116 according to actual conditions, thereby keeping the patient's breathing unobstructed to prevent the corresponding pipeline from being bent or falling off and affecting the patient's breathing state.

[0041] See also Figure 1 , Figure 2 , Figure 3 and Figure 6 In some embodiments, a groove 117 is opened inside the soft cushion 109, and a soft support column 118 is provided on the inner wall of the groove 117. The number of the grooves 117 is multiple, and the number of the soft support columns 118 is multiple with the number of the grooves 117.

[0042] In this embodiment, the patient's face will come into contact with the cushion 109, and after the cushion 109 is deformed, the patient's face will come into contact with the soft support column 118. The multiple soft support columns 118 can change the force distribution to avoid pressure injuries.

[0043] Specifically, the working principle of a head placement piece for prone position provided in the present application is:

[0044] The U-shaped frame 113 can be placed on the bed board, and then the lifting rod 114 is rotated. Since the lifting rod 114 and the U-shaped frame 113 are threadedly connected, the squeezing plate 115 can drive the anti-skid pad 120 to move until the anti-skid pad 120 contacts the bed board, and the bed board is squeezed by the anti-skid pad 120 to achieve fixation; according to the actual situation of the patient, the threaded rod 107 can be driven to rotate by the rotating plate 121. Since the threaded rod 107 is limited to rotation and cannot achieve position change, the slider 104 is displaced on the surface of the threaded rod 107, and the fixing column 105 is displaced with the slider 104. After it is rotated to a suitable position, the position of the rotating plate 121 can be fixed by the squeezing action of the fixing pad 122. In this process, the position and deflection angle of the connecting rod 106 are changed to change the position. The deflection angle of the base plate 101 can be changed, and the position of the cushion 109 can be adjusted according to the individual differences of the patients; the patient's face will be placed at the facial perforation 108, and the cushion 109 will contact the patient, and the elastic band 119 can contact the patient's forehead to ensure the stability of the patient's head position; the material of the cushion 109 includes but is not limited to the above-mentioned materials; the facial perforation 108 corresponds to the mirror 112, and the deflection angle of the mirror 112 can be changed by the universal joint 111, and then cooperate with the angle deflection of the base plate 101, and then the patient's face can be reflected, so that medical staff can check the patient's facial state in the prone position; the endotracheal tube can be passed through the endotracheal tube channel 116 according to actual conditions, so as to keep the patient's breathing unobstructed, so as to avoid the corresponding pipeline from being bent or falling off and affecting the patient's breathing state.
