Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to an oral medication delivery device for comatose patients. Background Technology

[0002] Comatose patients, due to loss of consciousness, are unable to cooperate with oral care and medication administration, posing numerous challenges to clinical nursing. Currently, oral medication administration for comatose patients mainly relies on manual operation. Medical staff must manually open the patient's mouth and then use tools such as cotton swabs and syringes to apply or spray the medication to the affected area.

[0003] When a patient's jaw is clenched, manually opening the mouth can easily cause damage to the gums and teeth, and it is difficult to maintain a stable operating space, which increases the difficulty of accurate medication application. When applying medication with traditional tools, the medication is prone to dripping or scattering, and cannot be directed to the wound, which not only causes waste but may also contaminate other areas of the oral cavity. Manual operation makes it difficult to accurately control the dosage of medication. Too much dosage may cause adverse reactions, while too little dosage will affect the treatment effect.

[0019] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0020] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways than those described herein, and therefore the invention is not limited to the specific embodiments disclosed in the following specification.

[0021] like Figure 5-6As shown, an oral medication application device for comatose patients includes a frame 1, a slider 10, a central shaft 11 rotatably connected to the center of the slider 10, a mounting frame 12 slidably connected inside the central shaft 11, the slider 10 slidably connected inside the frame 1, the central shaft 11 is a ball bearing, and the mounting frame 12 is slidably connected inside the ball bearing, so that the mounting frame 12 can rotate, extend and retract back and forth, and slide left and right, and the position of the mounting frame 12 can be easily adjusted.

[0022] like Figure 6 As shown, the mounting frame 12 is a hollow tubular frame, and two horizontal plates are fixedly connected inside the mounting frame 12, dividing the interior of the mounting frame 12 into three parts: left, middle and right. The medicine moves from right to left through the process of applying medicine, dispensing medicine, and spraying medicine.

[0023] Furthermore, the interior of the left horizontal plate of the mounting bracket 12 is equipped with a drive mechanism 14, and the interior of the hollow position in the middle of the mounting bracket 12 is equipped with a limiting mechanism 15. like Figure 6-7 As shown, the drive mechanism 14 includes a support rod 1401, which is slidably connected to the inside of the left horizontal plate. A rack 1402 is provided on the surface of the support rod 1401, and a drive gear 1403 is meshed on the side of the rack 1402. When the drive gear 1403 starts to rotate, the meshing with the rack 1402 drives the support rod 1401 to move to one side of the left horizontal plate.

[0024] like Figure 7 As shown, a pawl 1404 is rotatably connected to the side of the support rod 1401 away from the rack 1402. A ratchet gear 1405 meshes with the side of the mounting bracket 12 near the pawl 1404. A pressure rod 1406 is fixedly connected to the surface of the ratchet gear 1405. There are multiple pawls 1404, which are evenly distributed on the surface of the support rod 1401. A limit plate is fixedly connected to the right side of the pawl 1404. The shaft of the pawl 1404 is elastically connected to the support rod 1401 through a torsion spring 7. When the pawl... When pawl 1404 moves to the right, it collides with ratchet 1405 and rotates into the support rod 1401 without obstruction. When pawl 1404 moves to the left, it is blocked by the limiting plate and meshes with ratchet 1405, causing ratchet 1405 to rotate. The axis of ratchet 1405 is also elastically connected to the cross plate through torsion spring 7, so that ratchet 1405 maintains its original position when support rod 1401 moves to the right and starts to rotate when support rod 1401 moves to the left.

[0025] like Figure 7As shown, a movable plate 1407 is slidably connected to the lower side of the mounting bracket 12 near the ratchet 1405. A transmission rod 1408 is rotatably connected to the lower surface of the movable plate 1407. A sliding gear 1409 is rotatably connected to the end of the transmission rod 1408 away from the movable plate 1407. A motion groove is provided inside the horizontal plate on the left side of the mounting bracket 12. The movable plate 1407 is slidably connected inside the motion groove, and the ratchet 1405 is located at the top of the motion groove. When the ratchet 1405 rotates, the pressure rod 1406 can press the movable plate 1407 downward. A slide rail is provided inside the motion groove, and the sliding gear 1409 is slidably connected inside the slide rail. A torsion spring 7 is elastically connected inside the rotating shaft that rotatably connects the transmission rod 1408 and the sliding gear 1409. When the pressure rod 1406 rotates downward, it presses the movable plate 1407 downward. The downward movement of the movable plate 1407 drives the transmission rod 1408 to rotate. The rotation of the transmission rod 1408 drives the sliding gear 1409 to slide inside the slide rail.

[0026] like Figure 7 As shown, a transmission gear 1410 meshes with the lower side of the sliding gear 1409. A baffle 1411 is fixedly connected to the center of the transmission gear 1410. Through holes are provided on both the upper and lower sides of the horizontal plate on the left side of the mounting bracket 12. The baffle 1411 is rotatably connected inside the through hole, and the diameter of the baffle 1411 is the same as the diameter of the through hole. When the sliding gear 1409 slides, the transmission gear 1410 starts to rotate. The transmission gear 1410 drives the baffle 1411 to rotate, and the baffle 1411 opens the through hole. The powder inside the middle cavity of the mounting bracket 12 can enter the left side through the through hole.

[0027] like Figure 7-9 As shown, the limiting rod 1501 is fixedly connected to the center of the middle cavity of the mounting bracket 12. The limiting rod 1501 is inserted into the inside of the round shaft 1606, so that the push plate 1601 can slide on the surface of the limiting rod 1501.

[0028] like Figure 8-9 As shown, the limiting mechanism 15 includes a limiting rod 1501, a limiting groove 1502 is formed inside the limiting rod 1501, a limiting block 1503 is slidably connected inside the limiting groove 1502, an ejector spring 1504 is fixedly connected to the side wall of the limiting block 1503, an electromagnetic block 1505 is fixedly connected to the side of the limiting rod 1501 near the limiting groove 1502, the limiting groove 1502 is located on both sides of the limiting rod 1501, and the limiting block 1503 is a magnetic block. The near ends of the limiting block 1503 and the electromagnetic block 1505 are magnetic poles of the same name. When the electromagnetic block 1505 is energized, it generates a magnetic force to push the limiting blocks 1503 on both sides to overcome the elastic force of the ejector spring 1504 and move to the outside of the limiting groove 1502. When the push plate 1601 moves to the position of the limiting block 1503, it can be blocked, thus limiting the movement of the push plate 1601.

[0029] like Figure 8 As shown, the blocking mechanism 16 includes a push plate 1601, and a telescopic tube 1602 is fixedly connected to the side of the push plate 1601. The end of the telescopic tube 1602 away from the push plate 1601 is fixedly connected to the surface of the right horizontal plate. A through hole is opened on the surface of the right horizontal plate, and the axis of the telescopic tube 1602 and the center of the through hole are located on the same axis line.

[0030] like Figure 8 As shown, circular holes 1603 are provided on both sides of the surface of the push plate 1601. A one-way valve 1604 is provided inside the circular hole 1603. The axis of the telescopic tube 1602 and the center of the circular hole 1603 are on the same axis, so that the through hole on the right horizontal plate is connected to the circular hole 1603, and the powder can be transferred to the left side of the push plate 1601 during the transfer.

[0031] like Figure 8 As shown, a rubber strip 1605 is fixedly connected to the inside of the side wall of the push plate 1601. A round shaft 1606 is provided at the center of the surface of the push plate 1601. The cavity size of the push plate 1601 and the center position of the mounting bracket 12 are the same. The rubber strip 1605 on the edge increases the sealing of the push plate 1601. When the push plate 1601 moves to the left, the powder inside the cavity at the center position of the mounting bracket 12 can be pushed out.

[0032] like Figure 6 and 10 As shown in Figure -11, a connecting mechanism 17 is provided on the right side inside the mounting bracket 12, a snap-fit ​​mechanism 18 is provided on the right side of the mounting bracket 12 near the connecting mechanism 17, a syringe 13 is inserted into the rightmost end inside the mounting bracket 12, a hose 19 is fixedly connected to the left side inside the mounting bracket 12, and a fitting mechanism 20 is provided at the leftmost end of the mounting bracket 12.

[0033] like Figure 10-11 As shown, the connecting mechanism 17 includes a storage compartment 1701, and a connecting pipe 1702 is fixedly connected to the left side of the storage compartment 1701, as shown. Figure 11 As shown, a groove 1703 is formed inside the right sidewall of the storage chamber 1701, and a through hole is formed in the center of the right sidewall of the storage chamber 1701. The groove 1703 is formed inside the sidewall of the through hole. The injection head portion of the syringe 13 has the same diameter as the through hole. Figure 6 As shown, the end of the connecting pipe 1702 away from the storage compartment 1701 is connected to the horizontal plate, and the axis of the connecting pipe 1702 and the through hole on the surface of the horizontal plate are on the same axis, so that the storage compartment 1701 and the cavity at the center of the mounting bracket 12 are interconnected.

[0034] like Figure 11As shown, a sealing block 1704 is slidably connected inside the groove 1703. A compression spring 1705 is fixedly connected to the side of the sealing block 1704 near the bottom of the groove 1703. A sealing strip 1706 is fixedly connected to the side of the sealing block 1704 away from the compression spring 1705. The groove 1703 is an annular groove, and the sealing block 1704 is an annular block. The sealing strip 1706 is tightly attached to the surface of the injection head of the syringe 13, which enhances the sealing between the syringe 13 and the storage chamber 1701. When the powder is injected into the storage chamber 1701, the powder enters the telescopic tube 1602 through the connecting tube 1702 on the side of the storage chamber 1701, and enters the middle cavity of the mounting bracket 12 through the one-way valve 1604 inside the push plate 1601.

[0035] like Figure 10 As shown, the locking mechanism 18 includes a movable groove 1801, and a locking block 1802 is slidably connected inside the movable groove 1801. A positioning spring 1803 is fixedly connected to the surface of the locking block 1802 near the movable groove 1801. The surface of the locking block 1802 is made of rough rubber material, and the movable groove 1801 is an annular groove and the locking block 1802 is an annular block. When the syringe 13 is inserted into the mounting bracket 12, the locking block 1802 can clamp the end of the syringe 13 under the action of the positioning spring 1803. The friction between the locking block 1802 and the syringe 13 is large, which increases the stability of the syringe 13 inside the mounting bracket 12.

[0036] like Figure 12 As shown, the bonding mechanism 20 includes a nozzle 2001, an active cavity 2002 is provided inside the nozzle 2001, a corrugated tube 2003 is fixedly connected to the surface of the nozzle 2001, and a bonding piece is fixedly connected to the top end of the corrugated tube 2003. The bonding piece is a flexible plastic thin elastic sheet that is horizontal with the corrugated tube 2003 and can be bonded to the surface of the oral cavity.

[0037] like Figure 12 As shown, a pressure switch 2004 is fixedly connected to the top of the nozzle 2001, and an illumination lamp 2005 is fixedly connected to the edge of the nozzle 2001. A power supply is provided inside the mounting bracket 12, and the pressure switch 2004 is connected to the power supply.

[0038] like Figure 6-8 As shown in Figure 12, pressure switch 2004 is connected to, via wires, as shown in Figure 12. Figure 7 The drive gear 1403 shown is connected, and a motor is installed inside the shaft of the drive gear 1403. When the pressure switch 2004 is pressed, the motor is energized and drives the drive gear 1403 to rotate. The drive gear 1403 begins to rotate, enabling the bellows 2003 to fit around the wound in the oral cavity where medication needs to be sprayed. At this time, the mounting bracket 12 is pressed against the skin. Figure 12As shown, the pressure switch 2004 is pressed against the skin surface. When the pressure switch 2004 is pressed, the drive gear 1403 starts to work. The drive gear 1403 drives the support rod 1401 on its side to move to the left side of the mounting bracket 12. When the support rod 1401 moves to the left, the baffle 1411 opens the through hole inside the left horizontal plate. Figure 8 As shown, the end of the support rod 1401 is fixedly connected to the surface of the push plate 1601. At this time, the powder inside the central cavity of the mounting frame 12 is squeezed by the push plate 1601 and enters the inside of the hose 19 through the through hole of the left horizontal plate. It then enters the inside of the active cavity 2002 through the hose 19 and is sprayed onto the wound through the nozzle 2001.

[0039] like Figure 13 As shown, the triggering mechanism 21 includes a sliding frame 2101, which is fixedly connected to the surface of the mounting frame 12.

[0040] like Figure 8 and 13 As shown, the sliding frame 2101 has a sliding groove 2102 inside, and a sliding block 2103 is slidably connected inside the sliding groove 2102. Contacts 2104 are fixedly connected inside the side wall of the sliding groove 2102, and three contacts 2104 are arranged on the inner side wall of the sliding groove 2102, as shown. Figure 8 As shown, three electromagnetic blocks 1505 are fixedly connected inside the limiting rod 1501. The three electromagnetic blocks 1505 divide the limiting rod 1501 into three equal parts. The three contacts 2104 are connected to the three electromagnetic blocks 1505 inside the limiting rod 1501. like Figure 13 As shown, a circular groove 2105 is provided on the side wall of the sliding block 2103. A trigger block 2106 is slidably connected inside the circular groove 2105. A connecting spring 2107 is fixedly connected to the side of the trigger block 2106 near the bottom of the circular groove 2105. The mounting bracket 12 is equipped with a power supply. The trigger block 2106 is connected to the power supply through a wire. When the trigger block 2106 contacts the contact point 2104, the electromagnetic block 1505 is energized and pushes the limiting blocks 1503 on both sides out of the limiting groove 1502. When the push plate 1601 moves to this position, it can be limited by the limiting block 1503. The volume of the cavity between the left horizontal plate of the mounting bracket 12 and the push plate 1601 changes.

[0041] In this embodiment of the invention, specifically: the syringe 13 is inserted into the inside of the mounting frame 12 from the right side of the mounting frame 12, the end of the syringe 13 is snapped into the inside of the storage compartment 1701, and its end is snapped into the sealing block 1704, and the root position of the syringe 13 port is snapped into the snapping block 1802, so that the syringe 13 will not slip during injection and the stability of the syringe 13 is maintained.

[0042] Adjust the position of the front and rear and rotate the mounting bracket 12, and observe the position and size of the wound inside the patient's oral cavity through the illumination lamp 2005 at the top of the nozzle 2001. Then, attach the corrugated tube 2003 on the surface of the nozzle 2001 to the surface around the wound. At this time, adjust the position of the sliding block 2103 inside the sliding bracket 2101 according to the size of the wound. When the wound is small, slide the sliding block 2103 to the left side of the sliding bracket 2101. The trigger block 2106 contacts the contact point 2104 on the left side. At this time, the limiting block 1503 inside the left side of the limiting rod 1501 extends to the outside of the limiting groove 1502 under the push of the electromagnetic block 1505. The powder inside the syringe 13 is injected into the storage chamber 1701 and then fed into the telescopic tube 1602 through the connecting tube 1702 on the side of the storage chamber 1701. As the pressure increases, it breaks through the one-way valve 1604 and enters the cavity inside the mounting bracket 12 on the left side of the push plate 1601. As the amount of powder inside the cavity increases, the pressure gradually increases. Under the action of the pressure, the push plate 1601 moves to the right side of the cavity inside the mounting bracket 12 until it stops at the position of the limit block 1503, thus realizing the function of adjusting the amount of medicine sprayed.

[0043] Pushing the nozzle 2001 towards the skin causes the pressure switch 2004 to contact and be pressed. At this time, the motor inside the drive gear 1403 starts to rotate, and the drive gear 1403 rotates accordingly, driving the support rod 1401 to move to the left. When the support rod 1401 moves, the pawl 1404 engages with the ratchet gear 1405. The ratchet gear 1405 rotates and drives the pressure rod 1406 to press the movable plate 1407. When the movable plate 1407 moves downward, it drives the sliding gear 1409 to slide to the other side of the slide rail through the transmission rod 1408. The transmission gear 1410 engages with the sliding gear 1409. The rotation of the transmission gear 1410 drives the baffle 1411 to open the through hole inside the horizontal plate. The medicine enters the hose 19 and is sprayed onto the surface of the wound through the nozzle 2001. The corrugated tube 2003 wraps around the wound to prevent the medicine from spilling, thus achieving the effect of quantitative and targeted spraying of medicine powder according to the size of the wound.

[0044] like Figure 1-2 As shown, a lifting plate 2 is slidably connected to the side of the frame 1, a drive motor 3 is fixedly connected to the surface of the frame 1, and a threaded rod 4 is fixedly connected to the output shaft of the drive motor 3. A vertical groove is opened on the left side surface of the frame 1, and the threaded rod 4 is rotatably connected inside the vertical groove. A threaded groove is opened inside the lifting plate 2, and the threaded rod 4 is engaged inside the threaded groove. When the drive motor 3 is started, as the drive motor 3 rotates forward and reverses, it drives the threaded rod 4 to rotate forward and reverse, and the lifting plate 2 rises and falls along the surface of the threaded rod 4. like Figure 3-4As shown, a rotating plate 5 is rotatably connected to the side of the lifting plate 2 away from the frame 1. A roller 6 is rotatably connected to the outer surface of the rotating plate 5. A sponge pad is fixedly connected to the upper surface of the lifting plate 2. The surface of the roller 6 is wrapped with a sponge pad. The upper and lower rotating plates 5 are placed at an angle to form a cone. When the rotating plate 5 is inserted into the patient's mouth, the patient's mouth can be opened. The roller 6 on the surface of the rotating plate 5 rotates and rubs, and the surface is covered with a sponge pad to reduce the friction of the patient's teeth and prevent the teeth from being worn. When the patient's teeth move to the surface of the lifting plate 2 with the rotating plate 5, the drive motor 3 is started to rotate forward, the lifting plate 2 is lifted, and the patient's mouth is opened.

[0045] like Figure 4-5 As shown, the rotating shaft of the rotating plate 5 and the lifting plate 2 is provided with a torsion spring 7, the bottom of the rotating plate 5 is provided with a pulling mechanism 8, the right side surface of the frame 1 is provided with a slide groove 9, and the slider 10 is slidably connected inside the slide groove 9, so that the slider 10 can slide around the frame 1.

[0046] like Figure 5 As shown, the pulling mechanism 8 includes a support frame 801, a support plate 802 is fixedly connected to the inner wall surface of the support frame 801, a rotating roller 803 is fixedly connected to the surface of the support plate 802 away from the support frame 801, a torsion spring 7 is elastically connected inside the rotating roller 803, and the elastic force of the torsion spring 7 inside the rotating roller 803 is less than the elastic force of the torsion spring 7 inside the rotating plate 5, so that the rotating plate 5 can pull the rope 810.

[0047] like Figure 5 As shown, a rope-winding roller 804 is fixedly connected to the side of the rotating roller 803 away from the support plate 802. An insert rod 805 is fixedly connected to the surface of the support plate 802. A slide plate 806 is slidably connected to the surface of the insert rod 805. A slide rod 807 is fixedly connected to the side wall of the slide plate 806. A limit spring 808 is wound around the surface of the slide rod 807. A pressure plate 809 is fixedly connected to the end of the slide rod 807 away from the slide plate 806. A rope 810 is wound around the surface of the rope-winding roller 804. The end of the rope 810 away from the rotating roller 803 is fixedly connected to the lower surface of the rotating plate 5. When the pressure plate 809 is pressed, the pressure plate 809 drives the slide plate 806 to move into the support frame 801 through the slide rod 807. At this time, the insert rod 805 on the surface of the support plate 802 separates from the slide plate 806, the support frame 801 is not constrained, the torsion spring 7 at the rotating shaft of the rotating plate 5 drives the rotating plate 5 to rotate, the rope 810 is pulled out, and the rope-winding roller 804 rotates. When it is necessary to retrieve the rope 810, the rotating plate 5 rotates the roller 803, which is connected to the support frame 801 via the torsion spring 7. The support frame 801 drives the rotating roller 803 to rotate, and the rope winding roller 804 rotates accordingly, rewinding the rope 810 onto the surface of the rope winding roller 804. Then, the pressure plate 809 is released, and the sliding plate 806 returns to its original position under the action of the limit spring 808 and is inserted into the insertion rod 805 to lock the support plate 802, thus restricting the rotation of the rope winding roller 804.

[0048] Working principle: The rotating plate 5 is inserted into the patient's oral cavity. The roller 6 connected to the outer surface of the rotating plate 5 is wrapped with a sponge pad, which contacts the teeth to reduce friction damage. The drive motor 3 on the surface of the frame 1 is started. The output shaft of the motor drives the threaded rod 4 to rotate. The threaded rod 4 engages with the threaded groove inside the lifting plate 2, which drives the lifting plate 2 to rise along the vertical groove on the left side of the frame 1. The lifting plate 2 drives the rotating plate 5 to move synchronously, which smoothly opens the patient's oral cavity and avoids damage to the gums and teeth caused by manual operation.

[0049] The rotating plate 5 and the lifting plate 2 are equipped with torsion springs 7 inside the rotating shaft to provide initial support force. In the pulling mechanism 8, one end of the rope 810 is fixed to the lower surface of the rotating plate 5, and the other end is wound around the rope roller 804 to help fix the position of the rotating plate 5. Pressing the pressure plate 809 causes the slide plate 806 to slide along the insertion rod 805 through the slide rod 807, releasing the constraint on the support plate 802. The tension of the rope 810 can be adjusted to finely adjust the oral cavity opening angle to adapt to different patients' oral cavity sizes.

[0050] The slider 10 is slidably connected to the inside of the slide groove 9 on the right side of the frame 1. The central shaft 11, which is rotatably connected at the center of the slider 10, is slidably connected to the mounting bracket 12 inside the ball bearing. By sliding the slider 10, rotating the central shaft 11, and extending and retracting the mounting bracket 12, the position of the mounting bracket 12 is adjusted. The irradiation lamp 2005 on the edge of the nozzle 2001 in the left end of the mounting bracket 12 is turned on to observe the position of the oral wound and to accurately align the nozzle 2001 with the affected area.

[0051] The syringe 13 containing the drug is inserted from the rightmost end of the mounting frame 12 into the locking mechanism 18. The locking block 1802 in the movable groove 1801, under the action of the positioning spring 1803, tightly clamps the base of the syringe 13 to prevent it from slipping. The end of the syringe 13 is inserted into the right through hole of the storage chamber 1701 of the connecting mechanism 17. The sealing block 1704 in the groove 1703 on the right side wall of the storage chamber 1701, under the action of the compression spring 1705, adheres to the port of the syringe 13 through the sealing strip 1706 to ensure a leak-free seal. The piston of the syringe 13 is pushed, and the drug enters the storage chamber 1701. It flows into the telescopic tube 1602 through the connecting tube 1702 on the left side of the storage chamber 1701, and finally breaks through the one-way valve 1604 in the round hole 1603 on the surface of the push plate 1601 in the blocking mechanism 16 and enters the middle cavity of the mounting frame 12.

[0052] Depending on the size of the wound, the sliding block 2103 in the sliding frame 2101 of the surface triggering mechanism 21 of the sliding mounting frame 12 causes the trigger block 2106 in the circular groove 2105 on the side wall of the sliding block 2103 to contact the specific contact point 2104 on the side wall of the sliding groove 2102 under the action of the connecting spring 2107. The power supply in the mounting frame 12 is connected to the power supply of the corresponding electromagnetic block 1505 in the limiting rod 1501 in the limiting mechanism 15 through the trigger block 2106 and the contact point 2104. The electromagnetic block 1505 generates magnetic force, which pushes the limiting block 1503 in the limiting groove 1502 to overcome the elastic force of the ejection spring 1504 and extend, limiting the maximum sliding stroke of the push plate 1601, thereby controlling the amount of drug stored in the intermediate cavity and realizing dosage adjustment.

[0053] The medication enters the active cavity 2002 inside the nozzle 2001 through the tubing 19, and is finally sprayed from the nozzle 2001 onto the wound. The corrugated tube 2003 tightly fits around the wound to form a closed space, preventing the medication from scattering and contaminating other areas of the oral cavity, thus achieving precise and targeted drug delivery.

[0054] After a single medication application is completed, the drive gear 1403 reverses, causing the support rod 1401 to reset. The ratchet 1405 returns to its original position under the action of its own torsion spring. The pressure rod 1406 disengages from the movable plate 1407, and the baffle 1411 closes the through hole of the left horizontal plate. When filling the medication later, the push plate 1601 can store the medication again at the new dosage setting. Repeating the above process can achieve multiple precise medication applications.

[0055] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
