Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to an intelligent lip moisturizing device for patients after surgery. Background Art

[0002] Currently, in clinical hospitals, patients are often required to abstain from food and water for a period of time before and after surgery, which can lead to chapped lips. A common approach to addressing this chapped lip condition is to wet the lips with a cotton swab. However, this wet swab method is cumbersome and time-consuming, requiring frequent bedside care by a dedicated person, which increases the nursing workload. Patent application publication number CN118649345A discloses an intelligent lip balm device and method. The device comprises a lip balm box, a visual positioning camera disposed on the upper cover of the box, and a lip balm block disposed at the front end of the box. A water pipe has an inlet end extending into a liquid storage bottle and an outlet end extending into a hollowed-out groove, with an atomizing nozzle disposed at the outlet end. A guide rail assembly comprises an X-axis guide rail, a Z-axis guide rail, and a Y-axis guide rail connected in sequence, with the lip balm box connected to the X-axis guide rail. A support rod has one end fixedly connected to the Y-axis guide rail and the other end provided with a clamping buckle. The visual positioning camera, the guide rail assembly, a micro water pump, and a timer are all coupled to an integrated controller. Through the intelligent control of the visual positioning camera, guide rail assembly, micro water pump, and timer through an integrated controller, the lip moistening device can automatically spray water on the lips of patients who are deprived of water, reducing the pressure of care. The device also takes a photo to locate the patient's lips before each lip moistening, improving the accuracy of the lip moistening procedure. However, this technical solution still has the following drawbacks: the lip moistening device cannot be moved arbitrarily; the lip moistening device must maintain the position of the patient's head and cannot move with the patient's head; it cannot adapt to different patients' lips, such as swollen lips after surgery and asymmetrical lips after surgery; and the lip moistening medium remains in a liquid state when it is not in contact with the lips.

DETAILED DESCRIPTION

[0016] The following will provide a clear and complete description of the technical solutions in the embodiments of the present invention, in conjunction with the accompanying drawings. Obviously, the described embodiments are only a portion of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0017] As shown in Figure 1-7, an intelligent lip balm device for postoperative patients includes a chassis 1, and a self-locking universal wheel 2 is provided at the bottom end of the chassis 1. By providing the universal wheel 2 at the bottom end of the chassis 1, medical staff can move the lip balm device at will according to the on-site environment; the upper end of the chassis 1 is fixedly connected to an outer sleeve 3, and an inner sleeve 4 that can move up and down is provided in the outer sleeve 3, and the top end of the inner sleeve 4 is fixedly connected to a support plate 6, and a hinge rod assembly 12 is provided on the support plate 6, and a hinge rod assembly 12 is provided on the support plate 6. The hinged rod assembly 12 is a telescopic driving structure, and a shell 5 covering the driving structure is provided on the support plate 6. The other end of the hinged rod assembly 12 is movably connected to the connecting plate 13. The bottom end of the connecting plate 13 is provided with a movable structure 14. The bottom end of the movable structure 14 is fixedly connected to an elastic structure 15. The bottom end of the elastic structure 15 is threadedly connected to a lip balm block 16 with an adaptive lip shape. The bottom end of the lip balm block 16 is provided with a plurality of rectangularly arranged adaptive liquid supply components 165 that can resist discharge.

[0018] Specifically, the outer sleeve 3 is a vertical rectangular parallelepiped structure, the length of the inner sleeve 4 is smaller than the length of the inner wall of the outer sleeve 3, and the total length of the outer sleeve 3 and the inner sleeve 4 is greater than the height of the patient when lying flat; the articulated rod assembly 12 is formed by cross-hinging a plurality of connecting rod assemblies, the two intersection points of one end of the articulated rod assembly 12 are set at the bottom end of the support plate 6, and the other end is set at the upper end of the connecting plate 13, and the extendable length of the articulated rod assembly 12 is greater than the width of the bed; by setting a driving structure, the extension or shortening state of the articulated rod assembly 12 can be changed to adapt to the position of the patient's head; by setting the lip balm block 16 in the moving structure The bottom end of the structure 14 can adjust the moving distance of the lip balm block 16 according to the length of the patient's lips; because the patient's mouth is an arc-shaped structure, when the lip balm block 16 is always in a parallel state and moves, it can only moisturize the highest point of the patient's mouth, and the other positions cannot achieve the lip moisturizing effect. In this case, it is necessary to connect the elastic structure 15 to the upper end of the lip balm block 16. By providing the elastic structure 15, the lip balm block 16 can move up and down when passing through the lips, so as to completely apply the lip balm to the patient's lips; when it moves to the lip edge position, the lip balm block 16 is at the lowest point and can abut against the positions on both sides of the lips. When it moves to the lip high position, the lip balm block 16 can abut against the lip high position; The lip balm block 16 is deformed under the action of pressure, so that the bottom end of the lip balm block 16 forms a curved surface that matches the anatomical curve of the lips; when the bottom end of the lip balm block 16 touches the patient's mouth, it can be completely fitted. When the lip balm block 16 and the mouth reach a certain pressure, the adaptive liquid supply component 165 discharges liquid, achieving the effect of supplying liquid when in contact and stopping liquid when leaving the lips.

[0019] During operation, the lip balm device is pushed to make the outer surface of the outer sleeve 3 contact the edge of the bed, and the height of the inner sleeve 4 is adjusted so that the height of the support plate 6 is higher than the height of the patient lying flat; the driving mechanism is activated, and the hinged rod assembly 12 is extended to drive the lip balm block 16 to move to the lip position; the moving mechanism 14 is activated to adjust the distance the lip balm block 16 moves left and right according to the position of the patient's lips; To ensure the intelligence of the lip balm device, a visual positioning camera and a timer are provided at the upper end of the connecting plate 13, and an integrated controller is provided on the supporting plate 6. The visual positioning camera, driving structure, moving structure, and timer are all coupled to the integrated controller. In this embodiment, the timer can be integrated into the integrated controller. The integrated controller intelligently controls the visual positioning camera, driving structure, moving structure, and timer. The visual positioning camera locates the patient's lip position, controls the driving structure to move the lip balm block 16 to the patient's lip position, and controls the moving structure to move the lip balm block 16 left and right about the mouth. The timer records the time each time the intelligent lip balm device is activated and the duration of the left and right movement of the lip balm block 16. This allows for automatic and timed spraying of water on the lips of patients who are deprived of water, reducing nursing pressure. Furthermore, a photo is taken to locate the patient's lips before each lip balm treatment, improving the accuracy of the lip balm treatment. The integrated controller and timer can be integrated into a mobile device, such as a remote control, for flexible control of the intelligent lip balm device.

[0020] like Figure 3 As shown, first racks 31 are fixedly connected to both sides of the inner wall of the outer sleeve 3, and a first gear 18 meshing with the first rack 31 is provided at the bottom end of the inner sleeve 4. A stepping motor 19 is provided on any of the first gears 18.

[0021] Specifically, grooves 17 are provided on both sides of the bottom end of the inner sleeve 4, and symmetrical connecting rods are fixedly connected in the grooves 17. The first gear 18 is rotatably connected to the connecting rods. The vertical side walls of the groove 17 are provided with a base, and a stepping motor 19 is fixedly connected to the base; when adjusting the height of the inner sleeve 4, the stepping motor 19 is started, and the output end of the stepping motor 19 drives the first gear 18 on one side to rotate, and the first gear 18 is engaged with the first rack 31, and the inner sleeve 4 moves upward; in order to ensure that the inner sleeve 4 descends to a certain position for limiting, a block with the same transverse cross-section as the inner wall of the outer sleeve 3 is fixedly connected to the bottom end of the first rack 31.

[0022] like Figure 2 As shown, two first strip grooves 11 are provided on one side of the upper surface of the support plate 6 facing the hinged rod assembly 12, and the upper ends of the two hinged rods of the hinged rod assembly 12 corresponding to the first end of the support plate 6 are provided with guide rods, and the upper ends of the guide rods pass through the first strip grooves 11, and a second gear 10 is rotatably mounted on one of the guide rods, and the second gear 10 cooperates with the driving structure, and the upper end of the other guide rod is provided with a fixing block fixedly connected to the upper side surface of the support plate 6; Specifically, the driving structure includes two pulleys 7 rotatably connected to the support plate 6 and a belt 8 connected between the two pulleys 7. The belt 8 is provided with a second rack 9 meshing with the second gear 10 on the side facing the hinged rod assembly 12, and the bottom end of the support plate 6 is provided with a first motor that drives the pulley 7 to rotate; in order to meet the maximum or minimum distance that the hinged rod assembly 12 can move during the movement process, the length of the first strip groove 11 where the second gear 10 is located is set to be greater than the length of the first strip groove 11 where the fixed block is located; when the first motor is started, the output shaft of the first motor drives the pulley 7 on one side to rotate, and the pulley 7 drives the belt 8 to rotate, and the gear on the belt 8 rotates clockwise or counterclockwise and meshes with the second gear 10, and the second gear 10 drives the lower guide rod to move left and right, so that the hinged rod assembly 12 contracts or extends, and the position of the lip balm block 16 is adjusted.

[0023] like Figure 4 As shown, the movable structure 14 includes a long plate 141 fixedly connected to both sides of the connecting plate 13, a threaded rod 142 rotatably connected to the long plate 141, a guide rod 143 fixedly connected to the long plate 141, a slider 144 slidably connected to the guide rod 143 and an arc plate 145 fixedly connected to the slider 144, and the arc plate 145 can move left and right in the threaded rod 142.

[0024] Specifically, the connecting plate 13 is provided with a second strip groove of the same length and relative to the first strip groove 11 provided on the support plate 6, and the hinged rod assembly 12 is fixedly connected to a guide rod at the movable end and the fixed end on the connecting plate 13, and the fixed block fixedly connected to the guide rod is slidably connected to the connecting plate 13 and fixedly connected to the connecting plate 13 respectively; when the hinged rod assembly 12 is in a shortened state, the movable end of the hinged rod assembly 12 is at the edge of the second strip groove, and when the hinged rod assembly 12 is in an extended state, the movable end of the hinged rod assembly 12 is at the edge of the second strip groove close to the fixed end; The long strip 141 is placed longitudinally, and corresponding vertical openings are opened on the two long strips. The opening on the upper side is rotatably connected to the threaded rod 142, and the opening on the lower side is fixedly connected to the guide rod 143. One side of the connecting plate 13 is fixedly connected to the side plate, and one end of the threaded rod 142 passes through the long strip 141 and is connected to the second motor fixedly connected to the side plate. The curved plate 145 is consistent with the slide on the threaded rod 142; when working, the second motor is started, and the second motor drives the threaded rod 142 to rotate, and the curved plate 145 that contacts the threaded rod 142 moves left and right, and the slider 144 moves with the curved plate 145.

[0025] like Figure 5As shown, the elastic structure 15 includes a fixed cylinder 151 fixedly connected to the bottom end of the slider 144 , a moving cylinder 152 slidably connected in the fixed cylinder 151 , and a first spring 153 fixedly connected between the fixed cylinder 151 and the moving cylinder 152 .

[0026] Specifically, the bottom end of the fixed cylinder 151 is fixedly connected to a circular baffle, and the upper end of the movable cylinder 152 is fixedly connected to a circular plate that can abut against the circular baffle to prevent the movable cylinder 152 from shifting during movement; the depth inside the fixed cylinder 151 is greater than the height of the movable cylinder 152; in the initial state, the distance between the inner wall of the fixed cylinder 151 and the top of the movable cylinder 152 is greater than the distance from the highest point to the lowest point of the lips; when moisturizing the patient's lips, it is only necessary to make the lip moisturizing block 16 in the initial state abut against the corner of the mouth (at this time the first spring 153 is not compressed).

[0027] like Figure 5 As shown, the lip balm block 16 includes a connecting block 161 threadedly connected to the bottom end of the movable cylinder 152, a connecting shell 162 fixedly connected to the bottom end of the connecting block 161 and integrally formed, a flexible substrate 163 fixedly connected to the bottom of the connecting shell 162, an adaptive liquid supply component 165 fixedly connected to the inner side surface of the flexible substrate 163 and a ball 166 hinged to the bottom end of the adaptive liquid supply component 165, and the flexible substrate 163 is provided with a conical hole 1631 relative to the position of the adaptive liquid supply component 165.

[0028] Specifically, the bottom end of the movable cylinder 152 is provided with an external thread that mates with the inner wall of the connecting block 161. The flexible substrate 163 is made of medical silicone material. Under the elastic deformation of the silicone, the flexible substrate 163 forms a curved surface that matches the lips, which can adapt to the morphological differences between thin lips and thick lips. The diameter of the small diameter end of the tapered hole 1631 is larger than the diameter of the ball 166, which allows the ball 166 to have movement deviation in the vertical direction and the lateral rotation direction. To facilitate the injection of lip balm medium into the connecting shell 162, an injection hole 164 is provided at the upper end of the connecting shell 162, and a rubber stopper is installed in the injection hole 164. To facilitate medical staff or family members to inject lip balm medium in a timely manner, a hanging rod 20 is threadedly connected to the upper end of the outer shell 5. A refill bottle 21 containing lip balm medium is hung on the hanging rod 20. The refill bottle 21 is connected to the injection hole 164 by a hose. The length of the hose is greater than the longest distance after the hinged rod is deformed. The connecting shell 162 is filled with lip balm medium, which is water or lip oil.

[0029] like Figure 6As shown, the adaptive liquid supply assembly 165 includes an inverted piston cylinder 1651 fixedly connected to the tapered hole, a second spring 1652 fixedly connected to the top wall of the piston cylinder 1651, a piston rod 1653 fixedly connected to the bottom end of the second spring 1652, a hinged ball base 1654 threadedly connected to the bottom end of the piston rod 1653, and a piston 1655 fixedly connected to the piston rod 1653. The bottom end of the hinged ball base 1654 is provided with a ball 166. The outer side surface of the bottom end of the piston cylinder 1651 is provided with circumferentially arranged liquid permeable holes 1656 that communicate with the interior of the connecting shell 162. When in the initial position, the piston 1655 blocks the liquid permeable holes 1656. Specifically, a valve is provided on the liquid permeable hole 1656. In the initial position, the piston 1655 blocks the liquid permeable hole 1656. Initial state: the second spring 1652 is at its free length (pre-compression 0), and the piston 1655 is pressed against the entrance of the liquid permeable hole 1656 under the thrust of the second spring 1652, forming a seal; at this time, the liquid permeable hole 1656 is completely closed, the valve is closed, and liquid cannot pass through; when pressure is triggered: when the ball 166 contacts the lip and is subjected to vertical pressure, it pushes the hinged ball base 1654 upward, and the piston rod 1653 compresses the second spring 1652, driving the piston 1655 to move upward synchronously. When the pressure increases to a certain level, the valve opens, and an annular gap is formed between the piston 1655 and the liquid permeable hole 1656; the greater the resistance pressure, the greater the compression of the second spring 1652, and the annular gap The height of the annular gap increases linearly, and the liquid supply flow rate increases; the liquid stored in the connecting shell 162 enters the inner cavity of the piston cylinder 1651 through the annular gap of the liquid permeable hole 1656, and the liquid flows downward along the gap between the piston rod 1653 and the inner wall of the piston cylinder 1651, and finally seeps out from the surface of the ball 166; when the external pressure disappears, the second spring 1652 pushes the piston rod 1653 to move downward, and the piston 1655 re-blocks the liquid permeable hole 1656, and the liquid supply is terminated; the universal joint structure of the articulated ball base 1654 ensures that the ball 166 automatically returns to its initial position; the second spring 1652 and the piston 1655 are linked to achieve "liquid supply on demand" without the need for electronic sensors or external energy.

[0030] like Figure 7As shown, the ball 166 is provided with an inner shell 1661, a sustained-release layer 1662 and a contact layer 1663 from the inside to the outside; a countersunk hole is provided at the upper end of the inner shell 1661, a threaded hole is provided in the countersunk hole, and a threaded section provided at the bottom end of the articulated ball base 1654 is connected to the threaded hole; the sustained-release layer 1662 is a 3D printed honeycomb structure with a pore size of 100 μm, loaded with antimicrobial peptides or analgesics, and the microcapsules are triggered to rupture by the rotation and friction of the ball 166; the contact layer 1663 is a thermosensitive The gel layer has a phase change property at 32°C, and its contraction / expansion is triggered by body temperature to achieve adaptive lip fitting. It is bonded to the middle layer through plasma treatment. The sustained-release layer 1662 is etched with microchannels arranged spirally along the circumference of the ball 166, which is seamlessly integrated with the drug loading area. The microchannels and the drug sustained-release channels form a "main-branch" network to achieve precise controlled release. The surface of the contact layer 1663 is distributed with micron-sized holes, which are aligned with the outlet of the middle-layer microchannel. When heated and contracted, the holes expand by 30%, enhancing the efficiency of liquid seepage.

[0031] The working process of the intelligent lip moisturizing device for postoperative patients provided by the present invention is as follows: During use, the lip balm device is pushed to the side of the bed at the patient's head; the stepper motor is started to adjust the height of the inner sleeve 4 so that the height of the connecting plate 13 is greater than the head position; the visual positioning camera is turned on to locate the patient's lip position, and the first motor is started at this time to adjust the length of the hinged rod assembly 12 to the upper side of the patient's lips; the inner sleeve 4 is lowered so that the lip balm block 16 contacts the patient's lips; at this time, the flexible substrate 163 at the bottom end of the lip balm block 16 fits the patient's lips, and the ball 166 is pressed to move upward, and the lip balm medium enters the inner cavity of the piston cylinder 1651 from the liquid permeable hole 1656, and the lip balm medium enters from the microchannel and seeps out from the surface of the contact layer 1663; the second motor is started to move the lip balm block 16 left and right to moisturize the patient's lips (the timer starts at this time), and when the time is up, the longitudinal position of the inner sleeve 4 rises, and the lateral position remains unchanged; after completing the overall operation, medical staff can perform timed lip balm operations according to the patient's condition.

[0032] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
