DETAILED DESCRIPTION

[0020] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] The components of the embodiments of the present invention generally described and shown in the drawings herein may be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention.

[0022] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present invention.

[0023] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0024] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] Example 1 This embodiment provides a maternal postoperative pain assessment and medication device, such as Figure 1 and Figure 2 As shown, it includes a mounting base 1, a stepper motor 2 and a fixing ring 3 are fixedly mounted on the top of the mounting base 1, the stepper motor 2 is electrically connected to a pain assessor 9 connected to a human body, and a controller is electrically connected between the pain assessor 9 and the stepper motor 2. The pain assessor 9 assesses the postoperative pain of the parturient, and the pain assessor 9 transmits the assessment value to the controller, and the controller rotates the stepper motor 2 to a corresponding angle according to the postoperative pain value of the parturient.

[0026] like Figure 3-Figure 5 As shown, a conversion assembly 6 is provided at the end of the stepper motor 2, and the conversion assembly 6 includes a turntable 61, a coaxial disk 62, a first torque spring 63, a conversion disk 65, a notch 66 and a positioning assembly. The output shaft of the stepper motor 2 is fixedly connected to the turntable 61, and the center of the turntable 61 is rotatably connected to the coaxial disk 62 through a rotating shaft. The side of the coaxial disk 62 away from the turntable 61 is rotatably connected to the fixed ring 3, and the first torque spring 63 is elastically connected to the rotating shaft between the turntable 61 and the coaxial disk 62. A docking shaft 64 is fixedly installed on the side of the coaxial disk 62, and the end of the docking shaft 64 is fixedly connected to the conversion disk 65.

[0027] Among them, three control components 8 are arranged in a circular shape with equal angles inside the conversion disk 65. Different kinds of painkillers flow inside the three control components 8. A medicine receiving bottle is placed at the end of one of the control components 8. The stepper motor 2 drives the conversion disk 65 to rotate by using the turntable 61, the coaxial disk 62, the first torque spring 63 and the docking shaft 64, thereby changing the position of the control components 8 on the position conversion disk 65, so that the three control components 8 change their positions, so that the painkillers needed by the mother after surgery are moved to the medicine receiving bottle, and the appropriate painkillers are selected. like Figure 4 As shown, three notches 66 distributed in an annular manner with equal angles are provided on the arc surface of the coaxial disk 62, and a positioning component is provided on the side of the fixed ring 3. The positioning component is engaged with the notch 66 on the outer arc surface of the coaxial disk 62. The positioning component can fix the position of the quantity control component 8 where the selected painkiller tablets are located to avoid misalignment of the quantity control component 8 and the medicine bottle.

[0028] It is worth mentioning that the positioning assembly includes a latch tooth 67, a slide rail box 68 and a coil spring 69. The slide rail box 68 is fixedly installed on the side of the stepper motor 2. The internal sliding connection of the slide rail box 68 is connected to the latch tooth 67. The top of the latch tooth 67 is directly elastically connected to the slide rail box 68 and the coil spring 69. The bottom end of the latch tooth 67 adopts a triangular structure, and the latch tooth 67 is engaged with the notch 66 on the arc surface of the coaxial disk 62.

[0029] In addition, the rotation of the stepper motor 2 drives the turntable 61 to rotate. Since the coaxial disk 62 is limited by the latch tooth 67, the coaxial disk 62 and the turntable 61 jointly compress the first torque spring 63. When the elastic force generated by the compression of the first torque spring 63 is greater than the resistance of the latch tooth 67 and the slide rail box 68 to the coaxial disk 62, the latch tooth 67 is squeezed into the spiral spring 69, and the coaxial disk 62 can rotate. The elastic force of the first torque spring 63 rotates the coaxial disk 62 quickly, and moves another notch 66 on the coaxial disk 62 to the latch tooth 67. The latch tooth 67 engages the coaxial disk 62 again, thereby achieving the effect of converting the control component 8 and positioning the control component 8.

[0030] According to the three-step analgesia principle, pain is divided into mild pain, moderate pain and severe pain. Within the range of mild pain, the position of the quantity control component 8 remains unchanged. When the pain exceeds the mild pain, the elastic force generated by the compression of the first torque spring 63 is greater than the resistance of the latch teeth 67 and the slide rail box 68 to the coaxial disk 62, so that the position of the quantity control component 8 is changed, and the pain-relieving tablets suitable for moderate pain can be released. Before the quantity control component 8 is changed, the position of the quantity control component 8 remains unchanged, and the quantity control component 8 is always aligned with the medicine bottle.

[0031] In this embodiment, a support rod 4 is fixedly mounted on the side of the fixed ring 3, a support ring 5 is fixedly mounted on the end of the support rod 4, the conversion disk 65 rotates at the inner ring of the support ring 5, a protective shell is clamped on the outside of the support ring 5, and an avoidance groove is provided on the protective shell. The protective shell prevents the control assembly 8 from touching the medical staff during conversion.

[0032] In this embodiment, according to the three-step analgesia principle, when the pain exceeds mild pain, the elastic force generated by the compression of the first torque spring 63 is greater than the resistance of the latch teeth 67 and the slide box 68 to the coaxial disk 62, so that the position of the quantity control component 8 is changed, and the pain-relieving tablets suitable for moderate pain can be released at this time. Before the quantity control component 8 is changed, the position of the quantity control component 8 remains unchanged, and the quantity control component 8 is always aligned with the medicine receiving bottle. After the change, the quantity control component 8 where the moderate pain-relieving tablets are located is transferred to the medicine receiving bottle, and the position of the quantity control component 8 is automatically changed and aligned with the medicine receiving bottle to prevent it from falling.

[0033] Example 2 Based on Example 1, this example proposes a maternal postoperative pain assessment and medication device, such as Figure 5 and Figure 6As shown, an insertion component 7 is provided on the side of the fixed ring 3, and the insertion component 7 includes a medicine tube 71, a first magnetic plate 73, an avoidance spring 74 and a misalignment platform 75. The medicine tube 71 passes through the conversion disk 65 and slides left and right along the axial direction of the conversion disk 65. The end of the medicine tube 71 is fixedly installed with the avoidance spring 74, and the end of the avoidance spring 74 is fixedly installed with the first magnetic plate 73. The misalignment platform 75 is fixedly installed on the side of the fixed ring 3 away from the coaxial disk 62, and the end of the misalignment platform 75 adopts an inclined surface structure.

[0034] In this embodiment, a second magnetic plate 76 is fixedly installed at the inclined surface of the offset platform 75 and at the tip. The second magnetic plate 76 has opposite magnetism to the end facing the first magnetic plate 73. When the coaxial disk 62 drives the docking shaft 64 and the conversion disk 65 to rotate to convert the quantity control component 8, the conversion disk 65 drives the medicine tube 71 to rotate, and the medicine tube 71 drives the first magnetic plate 73 to rotate. When the quantity control component 8 where the selected painkiller tablet is located moves to the extension line of the second magnetic plate 76, the offset platform 75 and the second magnetic plate 76 push the first magnetic plate 73, and the first magnetic plate 73 and the telescopic rod 72 extend, thereby extending the quantity control component 8 where the selected painkiller tablet is located.

[0035] like Figure 6 As shown, a telescopic rod 72 is passed through the axis of the avoidance spring 74, and the two ends of the telescopic rod 72 are fixedly connected to the medicine tube 71 and the first magnetic plate 73 respectively. Three medicine tubes 71 are arranged and distributed at equal angles in a ring shape on the conversion disk 65. A clearance opening 77 is opened at the center of the offset platform 75.

[0036] When the quantity control component 8 is extended, if there is an obstacle at the end of the quantity control component 8, the quantity control component 8 and the medicine tube 71 jointly compress the avoidance spring 74 to avoid it. The avoidance spring 74 is used for buffering to prevent the quantity control component 8 from extending quickly and hitting the human body to cause injury. The telescopic rod 72 prevents the avoidance spring 74 from bending under force.

[0037] The elastic force of the air spring is smaller than the elastic force of the avoidance spring 74. The tube body of the medicine tube 71 is connected to the analgesic tablet delivery tube. After the first magnetic plate 73 is squeezed by the offset platform 75 and the second magnetic plate 76, the medicine tube 71 is pushed toward the direction of the conversion disk 65, so that the control assembly 8 is extended. The three control assemblies 8 are quickly switched positions through the conversion assembly 6. After the switch, the control assembly 8 is quickly extended and extends into the medicine bottle.

[0038] The medicine tube 71 is extended through the repulsive force between the second magnetic plate 76 and the first magnetic plate 73, so that the quantity control component 8 is extended. During the rotation of the conversion disk 65, there must be a quantity control component 8 that does not need to take medicine and is located on the extension line of the second magnetic plate 76. Since the conversion disk 65 rotates quickly, the repulsive force between the second magnetic plate 76 and the first magnetic plate 73 is short. After the second magnetic plate 76 and the first magnetic plate 73 are misaligned, the magnetic force of the first magnetic plate 73 attracts the misalignment platform 75. Since the position of the misalignment platform 75 cannot be changed, the first magnetic plate 73 moves toward the direction of the misalignment platform 75. Therefore, the medicine tube 71 will not be pushed out to avoid the quantity control component 8 that does not need to take medicine from extending. At the same time, since there is a distance between the second magnetic plate 76 and the first magnetic plate 73, when the quantity control component 8 encounters an obstacle after extending, there is a distance between the second magnetic plate 76 and the first magnetic plate 73 as an avoidance space.

[0039] In this embodiment, after the quantity control component 8 is converted, the first magnetic plate 73 is squeezed by the offset table 75 and the second magnetic plate 76 to push the medicine tube 71 in the direction of the conversion disk 65, so that the quantity control component 8 is extended and the quantity control component 8 is extended into the medicine receiving bottle to prevent the painkiller tablets from falling. When the medicine receiving bottle is not placed in the right position, the extension of the quantity control component 8 is hindered, and the medicine tube 71, the first magnetic plate 73 and the offset table 75 compress the avoidance spring 74 to avoid the quantity control component 8 from knocking over the medicine receiving bottle.

[0040] Example 3 Based on the above-mentioned embodiment 1 or 2, this embodiment proposes a maternal postoperative pain assessment and medication device, such as Figure 7 and Figure 8 As shown, the quantity control component 8 includes a sleeve 81, an extension tube 82, an elastic baffle 83, a guide cylinder 84 and a medicine discharging turntable 85. The sleeve 81 is fixedly mounted on the conversion disk 65. The interior of the extension tube 82 is slidably connected to the sleeve 81. The end of the sleeve 81 is connected to the medicine tube 71. The guide cylinder 84 is fixedly mounted on the side of the conversion disk 65. The inner wall of the sleeve 81 is rotatably connected to the medicine discharging turntable 85. The outer wall of the extension tube 82 is fixedly mounted with an elastic baffle 83. The elastic baffle 83 adopts an L-shaped structure. The bending part of the elastic baffle 83 is inserted into the extension tube 82 and is close to the position of the medicine discharging turntable 85.

[0041] When the extension tube 82 is retracted into the sleeve 81, the elastic baffle 83 is in a compressed state, and the elastic baffle 83 blocks the end outlet of the extension tube 82; when the extension tube 82 is extended from the sleeve 81, the elasticity of the elastic baffle 83 causes it to move and open the end outlet of the extension tube 82, thereby discharging the painkiller tablets.

[0042] like Figure 7As shown, the medicine discharging rotating rack 85 adopts a water-draining structure, and has a plurality of water-draining grooves on the medicine discharging rotating rack 85. The water-draining grooves store painkilling tablets, and the first magnetic plate 73 closes the water-draining groove at the lowest position, and the end of the first magnetic plate 73 contacts the medicine discharging rotating rack 85. The painkilling tablets are received by the water-draining grooves, and the number of painkilling tablets in the water-draining grooves is limited, thereby controlling the discharge amount of the painkilling tablets.

[0043] like Figure 8 As shown, the inner wall of the extending tube 82 is rotatably connected to a positioning rotating plate 86, and a second torque spring 87 is elastically connected between the positioning rotating plate 86 and the extending tube 82. A one-way limit block 88 is fixedly installed on the side of the positioning rotating plate 86, and the top surface of the one-way limit block 88 is in contact with the extending tube 82. The positioning rotating plate 86 is located on the rotation path of the medicine discharging rotating plate 85.

[0044] It should be noted that when the elastic baffle 83 is pressed into the extension tube 82 by the sleeve 81, the elastic baffle 83 pushes the medicine dispensing turntable 85 to rotate. The thrust of the elastic baffle 83 on the medicine dispensing turntable 85 is greater than the resistance of the positioning turntable 86. At this time, the medicine dispensing turntable 85 rotates one grid. At this time, there are painkiller tablets between the water drainage groove and the elastic baffle 83. When the elastic baffle 83 extends out of the sleeve 81, the elastic baffle 83 pops out from the extension tube 82 by elastic force, and the elastic baffle 83 opens the water drainage groove to discharge the painkiller tablets inside it.

[0045] Due to the cooperation between the medicine discharging turntable 85, the positioning turntable 86 and the second torque spring 87, the medicine discharging turntable 85 has a one-way rotation function. There are tablets in the water discharge groove of the left half of the medicine discharging turntable 85, while there are no tablets in the water discharge groove of the right half of the medicine discharging turntable 85. At this time, the medicine discharging turntable 85 is driven to rotate by the tablets, but the positioning turntable 86 limits the position of the medicine discharging turntable 85, so that the paddles on the medicine discharging turntable 85 are in a vertical state, so that the elastic blocking piece 83 can push the medicine discharging turntable 85 when it is extended next time.

[0046] In this embodiment, when the elastic baffle 83 is pressed into the extension tube 82 by the sleeve 81, the elastic baffle 83 pushes the medicine dispensing rotary 85 to rotate, so that the painkilling tablets enter the water drainage groove of the medicine dispensing rotary 85. When the elastic baffle 83 extends out of the sleeve 81, the elastic baffle 83 pops out from the extension tube 82 by elastic force, and the elastic baffle 83 opens the water drainage groove to discharge the painkilling tablets therein. The medicine dispensing rotary 85 is used to control the amount of medicine discharged to avoid discharging multiple painkilling tablets at one time.

[0047] The above specific embodiments are only several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant inspirations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
