This emergency gastric lavage nursing assistance device includes a bed frame 1. The bed frame 1 is a square frame structure. Semi-circular plates 11 are provided on the opposite sides of the bottom of the bed frame 1. The centers of the semi-circular plates 11 are located above the horizontal plane of the bed frame 1. Bed backs 15 are provided on the opposite sides of the top of the bed frame 1. A bed seat 14 is installed in the middle of the bed frame 1. A flipping component 6 is provided below the bed seat 14. The bed frame 1, the semi-circular plates 11, the bed seat 14 and the bed backs 15 are an integral whole. The flipping component 6 is used to drive the bed frame 1 to rotate arcuately with the center of the semi-circular plates 11 as the axis. A bed board 7 is provided above the bed seat 14. Pull handles 71 are respectively installed on the opposite sides of the bed board 7. The pull handles 71 are located on one side of the bedside, facilitating the pushing and pulling operation of the bed board 7. A locking groove 72 is opened on one side of the bed board 7 close to the bed back 15. A locking component 3 is provided at the bottom of the bed back 15. The locking component 3 is used to lock the bed board 7. Pressing components 2 are respectively provided on the opposite sides of the bed back 15. The locking component 3 includes a locking seat 31, and the pressing component 2 includes a pressing frame 26. Blocking components 4 are provided on the opposite sides of the semi-circular plates 11. The blocking components 4 include baffle plates 41. A driving component 5 is provided below the bed seat 14. The driving component 5 is used to drive the baffle plate 41 to rotate to a state perpendicular to the bed seat 14, so that the locking seat 31 is inserted into the locking groove 72 for locking, and the pressing frame 26 rotates to a state parallel to the bed seat 14.

[0041] Combined with the attached Figure 3 , Figure 4 , Figure 6 and Figure 7 , an activity groove 151 is opened at the bottom of the bed back 15. The locking seat 31 is limited to move in the activity groove 151. Two bevels are symmetrically opened on the side of the locking seat 31 facing the locking groove 72, which are used to guide the elastic insertion of the locking seat 31 into the locking groove 72. At the center position of the top of the locking seat 31, on the side away from the bed seat 14, a U-shaped groove 33 is opened. An armrest 36 is installed in the middle of the U-shaped groove 33. Two pin shafts 35 are oppositely arranged in the U-shaped groove 33. One end of the pin shaft 35 is connected to a connecting plate 34. The connecting plate 34 is connected to the bed back 15. A spring 37 is sleeved outside the pin shaft 35. The spring 37 is used to drive the locking seat 31 to move towards the locking groove 72. The other end of the pin shaft 35 movably penetrates to the side of the locking seat 31 away from the bed back 15. The end of the locking seat 31 away from the bed back 15 is inserted and matched with the locking groove 72. When the bed board 7 is replaced, the specific operation is as follows: Push the bed board 7 directly from the side of the bed frame 1 onto the bed seat 14. As the bed board 7 is pushed, the two sides of the bed board 7 abut against the bevels of the locking seats 31 on both sides, so that the locking seats 31 move away from the bed board 7. During this process, the end of the pin shaft 35 is always located inside the locking seat 31. The two sides of the locking groove 72 of the bed board 7 are respectively attached to the side of the bed back 15. As the bed board 7 is continuously pushed, the locking seat 31 is driven by the spring 37 to be inserted into the locking groove 72. At this time, the bed board 7 is exactly installed above the bed seat 14.

[0042] Combined with the attached Figure 2 、 Figure 6 and Figure 7 , on the side of the locking seat 31 away from the bed base 14, two abutting grooves 32 are relatively provided. On one side of the baffle 41, an L-shaped plate 42 is vertically connected. On the side of the L-shaped plate 42 away from the baffle 41, a pressing plate 43 is installed. The pressing plate 43 has a triangular structure. When the baffle 41 rotates to a state perpendicular to the bed base 14, the pressing plate 43 is made to cooperate and abut against the abutting groove 32, as Figure 1 shown in the state. When the baffle 41 is parallel to the bed base 14, it is suitable for pushing or pulling out the bed board 7 at this time, as Figure 2 shown. When the baffle 41 is in a state perpendicular to the bed base 14, at this time, the baffle 41 rotates from the horizontal state to the vertical state, and the L-shaped plate 42 rotates to a state close to the headboard 15. At this time, exactly the pressing plate 43 presses downward at the position of the abutting groove 32, and exactly the movement of the locking seat 31 that has been in an inserted state with the locking groove 72 is limited, thereby realizing the locking of the installation of the bed board 7. And the baffle 41 in the vertical state is located on both sides of the bed frame 1 and flips with the bed frame 1 to play a protective role for the patients on the bed board 7. Through the driving assembly 5, the gear position assembly 4 can be controlled to return to the horizontal state, and the locking of the bed board 7 is unlocked. At this time, the bed board 7 can be directly pulled away from the bed base 14, realizing the convenient installation of the bed board 7 and facilitating the flipping and gastric lavage care of a batch of patients.

[0043] Combined with the attached Figure 1 、 Figure 2 、 Figure 3 、 Figure 9 and Figure 10 , the flipping assembly 6 includes a protective box 62. On the opposite sides of the protective box 62, base plates 16 are respectively installed. The base plates 16 are used to support the semi-circular arc plate 11. On the side of the base plate 16 away from the protective box 62, side plates 64 are installed. The top of the base plate 16 has an arc-shaped structure. The bottom of the semi-circular arc plate 11 is seated above the base plate 16. On the side of the semi-circular arc plate 11 close to the side plate 64, an arc-shaped sliding strip 12 is installed. On the side of the side plate 64 close to the base plate 16, an arc-shaped groove 641 is provided. The two ends of the arc-shaped groove 641 respectively penetrate through both sides of the side plate 64. The arc-shaped sliding strip 12 is limited to slide in the arc-shaped groove 641 to limit the flipping of the semi-circular arc plate 11 and ensure the stability of the flipping of the bed frame 1. A number of racks 13 are equidistantly installed on the inner side of the semi-circular arc plate 11. A gear 61 is arranged inside the semi-circular arc plate 11. The gear 61 is meshed and matched with the rack 13. A driving shaft 65 is concentrically connected between the two gears 61. The end of the driving shaft 65 is movably connected to the side plate 64. By rotating the gear 61, the rack 13 is pushed to move, so that the semi-circular arc plate 11 rotates in an arc along its own center. When it rotates to the state where the bed board 7 faces the right, it is in a state of flipping to the right. When it rotates in the reverse direction to the state where the bed board 7 faces the left, it is in a state of flipping to the left.

[0044] Combined with the attached Figure 9 and Figure 10 , a third worm gear 66 is concentrically connected to the outside of the drive shaft 65. A third worm 68 is arranged in cooperation with the lower part of the third worm gear 66. A second motor 67 is installed in the protective box 62. The output shaft of the second motor 67 is concentrically installed with the third worm 68. A protective cover 63 is installed on the top of the protective box 62. The protective cover 63 is located below the bed base 14. By controlling the rotation of the third worm 68 with the second motor 67, and using the transmission effect of the third worm 68 on the third worm gear 66, the rotation of the drive shaft 65 is realized. When the second motor 67 drives in the reverse direction, the corresponding drive shaft 65 drives in the reverse direction.

[0045] Embodiment 2

[0046] Refer to Figure 1-8 , which is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is:

[0047] Combined with the attached Figure 1 , Figure 5 , Figure 7 and Figure 8 , a first rotating shaft 22 is installed at the bottom of the pressing frame 26. One end of the first rotating shaft 22 is movably connected to the headrest 15. The other end of the first rotating shaft 22 is concentrically sleeved with a first worm gear 21. A first worm 23 is arranged below the first worm gear 21. A second rotating shaft 24 is movably installed on one side of the headrest 15. The first worm 23 is concentrically sleeved outside the second rotating shaft 24. The bottom of the side of the L-shaped plate 42 close to the baffle 41 is connected with a third rotating shaft 44. The driving assembly 5 includes two parallel fourth rotating shafts 51. The two ends of the fourth rotating shaft 51 respectively pass through the two semi-circular plates 11 movably. The third rotating shaft 44 is concentrically connected to the end of the fourth rotating shaft 51. The second rotating shaft 24 and the end of the fourth rotating shaft 51 are synchronously driven by a first synchronous belt 25. A plurality of spline grooves are provided at the end of the fourth rotating shaft 51. A plurality of spline teeth are arranged on the inner side of the first synchronous belt 25. A plurality of spline grooves are provided at the end of the second rotating shaft 24. The principle of the rotation of the pressing and positioning assembly 2 is: when the fourth rotating shaft 51 starts to rotate, it drives the third rotating shaft 44 to rotate 90°, so that the baffle 41 rotates from the horizontal state to the vertical state; at the same time, when the fourth rotating shaft 51 rotates, through the transmission of the first synchronous belt 25, the second rotating shaft 24 rotates 90°, so that the first worm 23 meshes with the first worm gear 21 and drives, so that the pressing frame 26 rotates 90°. The pressing frame 26 rotates from the vertical state to the horizontal state. The horizontal pressing frame 26 presses on the body part of the patient without affecting the part for gastric lavage, and it is not the head and crotch. In this way, the pressing and positioning assembly 2 rotates along with the bed frame 1. During the rotation process, the pressing frame 26 and the baffle 41 assist in positioning the patient's body to ensure the balance of the patient's body and achieve a better effect of gastric lavage.

[0048] Combined with the attached Figure 5and Figure 8 , two fifth rotating shafts 52 are arranged in parallel at the bottom of the bed base 14. The axis line of the fifth rotating shaft 52 is perpendicular to the axis line of the fourth rotating shaft 51. A number of first positioning seats 55 and a number of second positioning seats 56 are respectively installed at the bottom of the bed base 14. The fourth rotating shaft 51 movably penetrates through the corresponding first positioning seats 55, and the fifth rotating shaft 52 movably penetrates through the corresponding fifth rotating shaft 52. A first motor 58 is installed in the middle of the bed base 14. The first motor 58 and the two fifth rotating shafts 52 are synchronously driven by a second synchronous belt 57. The axis line of the first motor 58 and the axis lines of the two fifth rotating shafts 52 are not in the same horizontal plane, so that the second synchronous belt 57 is driven in a triangular state. A number of spline teeth are arranged on the inner wall of the second synchronous belt 57. A number of spline grooves are arranged at the corresponding positions of the output shaft of the first motor 58 and the fifth rotating shaft 52. The spline teeth are engaged with the spline grooves. The end of the fifth rotating shaft 52 is concentrically connected with a second worm 53. A second worm gear 54 is arranged below the second worm 53. The second worm gear 54 is concentrically sleeved outside the fourth rotating shaft 51. The principle of the driving assembly 5 for driving the fourth rotating shaft 51 to rotate is as follows Figure 8 As shown in the figure, by rotating the first motor 58, the driving direction of the second synchronous belt 57 is controlled, so that the two fifth rotating shafts 52 rotate. The ends of the fifth rotating shafts 52 are respectively controlled to rotate at the ends of the fourth rotating shafts 51 through the meshing of the second worm 53 and the second worm gear 54. According to the designed driving direction of the second worm 53 and the second worm gear 54, the two fourth rotating shafts 51 rotate simultaneously, but in opposite directions. Thus, the bed bases 14 on both sides of the headrest 15 can be respectively rotated from the horizontal state to the vertical state. And through the design of the driving direction of the pressing frames 26 and the first worm 23 on both sides of the headrest 15, the pressing frames 26 on both sides of the headrest 15 can be simultaneously rotated from the vertical state to the horizontal state
