Description

Technical Field

[0001] This invention relates to the field of oral surgery technology, specifically to an oral care device for postoperative oral and maxillofacial surgery. Background Technology

[0002] Postoperative care in oral and maxillofacial surgery involves a series of measures that patients must follow after surgery to promote wound healing, reduce the risk of complications, and ensure that patients recover normal function as soon as possible. These measures mainly include wound care, oral hygiene, dietary regulation, hot and cold compresses, and pain management. Among these, wound care and oral hygiene are particularly important, as they directly affect the healing of the surgical site and the patient's overall recovery.

[0003] For example, an oral care device for postoperative use in oral and maxillofacial surgery, as disclosed in announcement number CN119770783A, includes a body assembly and an oral sealing mechanism. The body assembly includes a main base, side bases, and a media storage bottle. The side bases are snapped onto one side of the main base, the media storage bottle is located on one side of the main base, and the oral sealing mechanism is located above the main base. Two rotating frames are driven by a micro-gear motor. The rotating frames, in conjunction with rolling rollers, roll the outer sides of the media delivery pipe and the drainage pipe, respectively. This allows for the simultaneous injection of medication or saline solution into the patient's oral cavity using the media delivery pipe and media guiding mechanism, while the drainage pipe, in conjunction with the media guiding mechanism, removes accumulated fluid from the patient's oral cavity. This simplifies the oral care process and, by using an injection method, reduces the impact on oral wounds during care, improving patient comfort.

[0004] Post-operative oral wound care requires adjustments to the position of the infusion head based on the healing stage. The core principle is to avoid blood clots in the wound and gradually move towards the cleaned area. The infusion head should be at least 5 mm away from the wound surface, aiming at the wound edge for infusion. Direct infusion at the center of the blood clot is prohibited. In clinical practice, a low flow rate should be used for the core area of ​​the wound to avoid excessive water pressure that could open sutures, damage newly formed granulation tissue, and prevent contaminants from being washed into deeper tissues, increasing the risk of infection. For the wound edge and other areas of the oral cavity, the infusion flow rate should be appropriately increased to more thoroughly remove residual secretions and ensure the effectiveness of oral care. Existing oral care infusion devices do not allow for flexible control of the infusion flow rate according to the wound location, and the injected care solution needs to be withdrawn promptly to avoid repeated soaking of the wound by stagnant liquid, which can prolong the wound healing time. Summary of the Invention

[0005] The purpose of this invention is to provide an oral care device for postoperative oral and maxillofacial surgery, which solves the problems of existing oral care injection devices, such as inconvenience in flexibly controlling the injection flow according to the wound location, poor adaptability, and inconvenience in timely extraction of the care solution.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a postoperative oral care device for oral and maxillofacial surgery, comprising a mounting cover, a connecting plate, and a blocking plate fixedly connected to one side of the mounting cover, wherein a liquid storage cylinder is fixedly connected to one side of the connecting plate;

[0007] Also includes:

[0008] The mounting cover is equipped with a liquid injection assembly, and the connecting plate is equipped with a drive assembly.

[0009] The injection assembly includes an injection tube and an extraction tube fixedly connected to one side of the baffle plate. An adjustment cover is vertically and rotatably installed inside the mounting cover. Two injection heads are installed in parallel inside the adjustment cover. A horizontal shaft and a gear are rotatably installed inside the adjustment cover. A main pulley is also fixedly connected to the outside of the horizontal shaft.

[0010] A fixed cylinder is fixedly connected to the side of the extraction tube away from the connecting plate, and a rotating cylinder is rotatably installed on the outside of the fixed cylinder.

[0011] Preferably, a vertical shaft is fixedly connected to the top of the adjusting cover, the vertical shaft is rotatably connected to the top of the mounting cover, a clamping bolt is threaded to the outer side of the vertical shaft, both injection heads are connected to injection pipes, and two baffles are symmetrically fixedly connected to both sides of the inner wall of the adjusting cover, the two baffles are slidably installed with the injection heads on both sides respectively.

[0012] By adopting the above technical solution, during injection, the injection head will move from both sides of the wound edge towards the center of the wound. As the injection head moves, the injection flow rate will automatically decrease, thereby maintaining a large flow rate injected into the wound edge area and a small flow rate injected into the wound center area. At the same time, when the injection flow rate of the injection head increases or decreases, the extraction flow rate of the extraction tube can be driven to increase or decrease accordingly.

[0013] Preferably, a limiting block is fixedly connected to the end of the baffle away from the adjusting cover. The limiting block is located inside the injection head. An electric push rod is fixedly installed vertically inside the adjusting cover. A fixing block is fixedly connected to the telescopic end of the electric push rod. A connecting block is fixedly connected to one side of the fixing block. The two connecting blocks are respectively fixedly connected to the two injection heads.

[0014] By adopting the above technical solution, the electric push rod drives the fixed block to move, the fixed block drives the connecting block and the injection head to move, the two injection heads move closer to each other, the baffle plate remains stationary, the baffle plate limits the movement of the injection head, thereby expanding the flow cross section inside the injection head, thus slowly increasing the injection flow rate of the injection head.

[0015] Preferably, a toothed plate is fixedly connected to the outside of the connecting block, two vertical plates are symmetrically fixedly connected to the inner bottom surface of the adjusting cover, the horizontal shaft is rotatably installed between the two vertical plates, the gear is fixedly connected to the horizontal shaft, the two toothed plates are respectively located at the top and bottom of the gear, and both toothed plates are meshed with the gear.

[0016] By adopting the above technical solution, when the connecting block drives the toothed plate to move, the toothed plate will also drive the gear to rotate, so that the gear drives the horizontal shaft and the main pulley to rotate.

[0017] Preferably, a driven pulley is fixedly connected to the outer side of the rotating cylinder, and a toothed belt is adapted to connect the main pulley and the driven pulley. Both the main pulley and the driven pulley are meshed with the toothed belt. The toothed belt is slidably connected to the adjusting cover. A mounting plate is fixedly connected to one side of the bottom of the adjusting cover, and the mounting plate is fixedly installed with the extraction tube.

[0018] By adopting the above technical solution, the main pulley drives the driven pulley on the outside of the rotating drum to rotate through the toothed belt, thereby driving the rotating drum to rotate.

[0019] Preferably, a fixed disk is fixedly connected inside the fixed cylinder, and a turntable is fixedly connected inside the rotating cylinder. The fixed disk and the turntable are tightly fitted together. Four through holes 2 are symmetrically opened inside the fixed disk, and six through holes 1 are opened on the outer side of the turntable. Initially, only two of the through holes 1 and 2 overlap. After the turntable rotates forty-five degrees, four of the through holes 1 and 2 will overlap.

[0020] By adopting the above technical solution, when the injection head moves to the maximum distance, the rotating cylinder and the turntable rotate forty-five degrees, so that the number of connection holes between the two through holes one on the turntable and the through hole two on the fixed plate changes from two to four, thereby adapting to increase the extraction flow rate of the extraction tube.

[0021] Preferably, the drive assembly includes two cylinders that are fixedly installed in parallel inside the connecting plate. A breather valve is fixedly installed on one side of the top of the liquid storage cylinder. One side of the cylinder is fixedly connected to the injection pipe, and an inlet pipe is fixedly connected between the cylinder and the liquid storage cylinder. The other side of the cylinder is fixedly connected to the extraction pipe, and a discharge pipe is fixedly connected to the side of the other side of the cylinder closest to the liquid storage cylinder.

[0022] By adopting the above technical solution, the breather valve is used to maintain the air pressure balance inside the liquid storage tank.

[0023] Preferably, a fixed box is fixedly connected to the top of the connecting plate, a servo motor is fixedly installed inside the fixed box, a drive tooth is fixedly connected to the output end of the servo motor, a square groove is also opened on the top of the connecting plate, and a gear ring is rotatably installed on the middle of the outer side of the cylinder.

[0024] By adopting the above technical solution, the servo motor will drive the drive teeth to rotate, and the drive teeth will drive the gear rings on both sides to rotate, with the two gear rings rotating in the same direction.

[0025] Preferably, the drive tooth passes through the square groove and meshes with both gear rings. A connecting rod is fixedly connected to the inner side of the gear ring, and an impeller is fixedly connected to the side of the connecting rod away from the gear ring. The installation directions of the two impellers are opposite.

[0026] By adopting the above technical solution, the two impellers are installed in opposite directions. One impeller rotates forward and draws the nursing fluid from the storage tank through the cylinder. The nursing fluid enters the injection pipe, which facilitates subsequent injection operations. The other impeller rotates in reverse and draws the injected nursing fluid through the extraction pipe.

[0027] Compared with the prior art, the beneficial effects of the present invention are as follows: By setting up an injection assembly, during injection, the injection head moves from both sides of the wound edge towards the center of the wound. As the injection head moves, the injection flow rate automatically decreases, thus maintaining a large flow rate injected into the wound edge area and a small flow rate injected into the wound center area. Simultaneously, when the injection flow rate of the injection head increases or decreases, the extraction flow rate of the extraction tube can be driven to increase or decrease accordingly, making the extraction of the nursing solution compatible with the injection. This avoids excessive accumulation of nursing solution due to increased flow rate. It achieves both adapting the injection flow rate to different areas of the wound, avoiding damage to the wound area caused by excessive injection flow, and efficiently cleaning residues in the edge area. Furthermore, it can automatically adapt and adjust the extraction flow rate of the nursing solution after injection, reducing the soaking damage to the wound caused by residual nursing solution. This improves the adaptability and flexibility of oral wound injection. The specific details are as follows:

[0028] 1. By setting up the injection assembly, medical staff first loosen the clamping bolt, pull the adjusting cover to rotate, and the adjusting cover drives the clamping bolt to rotate, so that the injection head is aligned with the wound area. Then, tighten the clamping bolt to limit the vertical axis, which facilitates the angle adjustment of the adjusting cover and the injection head. Next, place the mounting cover inside the patient's mouth, and the patient bites down on the mounting cover. The baffle plate blocks the patient's mouth, reducing the outflow of nursing fluid. The nursing fluid is input into the injection tube through the drive assembly, and then flows into the two injection heads, and is injected into the wound area from the injection heads. By activating the two electric push rods to retract, the electric push rods drive the fixed block to move, and the fixed block drives the connecting block and the injection head to move. The two injection heads move closer to each other, and the baffle plate does not move. The baffle plate limits the movement of the injection heads, which expands the flow cross section inside the injection head, thereby slowly increasing the injection pressure. The fluid flow rate is adjusted, and the connecting block also drives the toothed plate to move. The movement of the toothed plate drives the gear to rotate, which in turn drives the horizontal shaft and the main pulley to rotate. The main pulley drives the driven pulley on the outside of the rotating cylinder to rotate via a toothed belt, thereby driving the rotating cylinder to rotate. The rotating cylinder drives the turntable to rotate, and when the injection head moves to the maximum distance, the rotating cylinder and the turntable rotate 45 degrees, which increases the number of connection holes between the two through holes one on the turntable and the two through holes two on the fixed plate from two to four. This allows for an increase in the extraction flow rate of the extraction tube, enabling the adjustment of the injection flow rate to suit different areas of the wound. This avoids damage to the wound area caused by excessive injection flow rate and efficiently cleans the residue in the edge area. It can also autonomously adjust the extraction flow rate of the post-injection care solution, reducing the soaking damage to the wound caused by residual care solution, and improving the adaptability and flexibility of oral wound injection.

[0029] 2. By setting up a drive assembly, the reservoir is filled with nursing fluid. The breather valve is used to maintain the air pressure balance inside the reservoir. The servo motor drives the drive gear to rotate, which in turn drives the gear rings on both sides to rotate. The two gear rings rotate in the same direction, which in turn drives the connecting rod to rotate. The connecting rod drives the impeller to rotate, and the two impellers are installed in opposite directions. One impeller rotates forward, drawing nursing fluid from the reservoir through the cylinder. The nursing fluid enters the injection tube, facilitating subsequent injection operations. The other impeller rotates in reverse, drawing the injected nursing fluid through the extraction tube. The extracted nursing fluid flows back through the discharge tube and is discharged into an external collection box, achieving stable input and injection of nursing fluid and synchronous extraction and recovery.

Detailed Implementation

[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] Please see Figure 1 - Figure 3 The present invention provides a technical solution: an oral care device for postoperative oral and maxillofacial surgery, including a mounting cover 1, a connecting plate 3 and a blocking plate 2 fixedly connected to one side of the mounting cover 1, and a liquid storage cylinder 4 fixedly connected to one side of the connecting plate 3.

[0046] like Figure 1 and Figure 3 - Figure 10 As shown, the installation cover 1 is equipped with an injection assembly 5. The injection assembly 5 includes an injection pipe 51 and an extraction pipe 52 fixedly connected to one side of the baffle plate 2. The injection pipe 51 is a flexible hose. An adjustment cover 54 is vertically and rotatably installed inside the installation cover 1. Two injection heads 56 are installed in parallel inside the adjustment cover 54. The extraction pipe 52 and the injection heads 56 are stainless steel pipes that will not bend. A horizontal shaft 513 and a gear 514 are rotatably installed inside the adjustment cover 54. A main pulley 515 is also fixedly connected to the outside of the horizontal shaft 513.

[0047] A vertical shaft 53 is fixedly connected to the top of the adjusting cover 54. The vertical shaft 53 is rotatably connected to the top of the mounting cover 1. A clamping bolt 55 is threadedly connected to the outside of the vertical shaft 53. Both injection heads 56 are connected to the injection pipe 51. Two baffles 57 are symmetrically fixedly connected to both sides of the inner wall of the adjusting cover 54. The two baffles 57 are slidably installed with the injection heads 56 on both sides. A sliding groove is opened on the outside of the injection head 56. The baffles 57 are slidably connected to the sliding groove. The connection gap of the sliding groove is provided with a sealing waterproof layer to reduce the leakage of the care solution.

[0048] A limit block is fixedly connected to the end of the baffle 57 away from the regulating cover 54. The limit block is located inside the injection head 56. An electric push rod 58 is fixedly installed vertically inside the regulating cover 54. A fixing block 59 is fixedly connected to the telescopic end of the electric push rod 58. A connecting block 510 is fixedly connected to one side of the fixing block 59. The two connecting blocks 510 are fixedly connected to the two injection heads 56 respectively.

[0049] A toothed plate 511 is fixedly connected to the outside of the connecting block 510. Two vertical plates 512 are symmetrically fixedly connected to the inner bottom surface of the adjusting cover 54. A horizontal shaft 513 is rotatably installed between the two vertical plates 512. A gear 514 is fixedly connected to the horizontal shaft 513. The two toothed plates 511 are located at the top and bottom of the gear 514 respectively. Both toothed plates 511 are meshed with the gear 514, so that when the two injection heads 56 approach each other, the two toothed plates 511 will drive the gear 514 to rotate in one direction.

[0050] A driven pulley is fixedly connected to the outer side of the rotating drum 519. A toothed belt 516 is adapted to connect the main pulley 515 and the driven pulley. Both the main pulley 515 and the driven pulley are meshed with the toothed belt 516 to maintain the stability of the transmission. The toothed belt 516 is slidably connected to the adjusting cover 54. A mounting plate 517 is fixedly connected to one side of the bottom of the adjusting cover 54. The mounting plate 517 is fixedly installed with the extraction tube 52.

[0051] A fixed cylinder 518 is fixedly connected to the side of the extraction tube 52 away from the connecting plate 3, and a rotating cylinder 519 is rotatably installed on the outside of the fixed cylinder 518.

[0052] A fixed plate 520 is fixedly connected inside the fixed cylinder 518. The outer ring of the fixed plate 520 is connected to the inner wall of the fixed cylinder 518. A turntable 521 is fixedly connected inside the rotating cylinder 519. The outer ring of the turntable 521 is connected to the inner wall of the rotating cylinder 519. The fixed plate 520 and the turntable 521 are tightly fitted together. Four through holes 2 are symmetrically opened inside the fixed plate 520. Six through holes 1 are opened on the outer side of the turntable 521. Initially, only two of the through holes 1 and 2 overlap. After the turntable 521 rotates forty-five degrees, four of the through holes 1 and 2 will overlap.

[0053] Example 1: As Figure 3 - Figure 10 As shown, medical staff first loosen the clamping bolt 55, pull the adjusting cover 54 to rotate, and the adjusting cover 54 drives the clamping bolt 55 to rotate, so that the injection head 56 is aligned with the wound area. Then tighten the clamping bolt 55 to limit the vertical axis 53, so as to facilitate the angle adjustment of the adjusting cover 54 and the injection head 56. Next, the mounting cover 1 is placed inside the patient's mouth, and the patient bites the mounting cover 1 with his teeth. The baffle plate 2 blocks the patient's mouth to reduce the outflow of nursing fluid. The nursing fluid is input into the injection tube 51 through the driving component 6, and then flows into the two injection heads 56, and is injected into the wound area from the injection heads 56.

[0054] By activating the two electric push rods 58 to retract, the electric push rods 58 drive the fixed block 59 to move, and the fixed block 59 drives the connecting block 510 and the injection head 56 to move. The two injection heads 56 move closer to each other, and the baffle plate 57 remains stationary. The baffle plate 57 limits the movement of the injection head 56, which expands the flow cross section inside the injection head 56, thereby slowly increasing the injection flow rate of the injection head 56. In addition, the connecting block 510 also drives the toothed plate 511 to move. The movement of the toothed plate 511 drives the gear 514 to rotate. The gear 514 drives the horizontal shaft 513 and the main pulley 515 to rotate. The main pulley 515 drives the driven pulley on the outside of the rotating cylinder 519 to rotate through the toothed belt 516, thereby driving the rotating cylinder 519 to rotate. The rotating cylinder 519 drives the turntable 521 to rotate.

[0055] When the injection head 56 moves to its maximum distance, the rotating cylinder 519 and the turntable 521 rotate 45 degrees, increasing the number of connection holes between the two through holes 1 on the turntable 521 and the through hole 2 on the fixed plate 520 from two to four. This allows for an increase in the extraction flow rate of the extraction tube 52, enabling the adjustment of the injection flow rate to suit different areas of the wound. This avoids damage to the wound area caused by excessive injection flow and efficiently cleans residues in the edge areas. Furthermore, it can autonomously adjust the extraction flow rate of the post-injection care solution, reducing the soaking damage to the wound caused by residual care solution, thus improving the adaptability and flexibility of oral wound injection.

[0056] Similarly, when the electric push rod 58 extends, the two injection heads 56 move away from each other and reset, the gear 514 and the horizontal shaft 513 rotate, causing the rotating cylinder 519 and the turntable 521 to also rotate, keeping the injection heads 56 reciprocating to inject fluid into the center and edge of the wound.

[0057] like Figure 1 and Figure 11 - Figure 13 As shown, a drive assembly 6 is provided inside the connecting plate 3. The drive assembly 6 includes two cylinders 61 that are fixedly installed in parallel inside the connecting plate 3. A breather valve 7 is fixedly installed on one side of the top of the liquid storage cylinder 4. The breather valve 7 keeps the air pressure inside the liquid storage cylinder 4 stable. One cylinder 61 is fixedly connected to the injection pipe 51, and an inlet pipe 62 is fixedly connected between the one cylinder 61 and the liquid storage cylinder 4. The other cylinder 61 is fixedly connected to the extraction pipe 52, and a discharge pipe 63 is fixedly connected to the side of the other cylinder 61 near the liquid storage cylinder 4.

[0058] A fixed box 64 is fixedly connected to the top of the connecting plate 3. A servo motor 65 is fixedly installed inside the fixed box 64. A drive gear 66 is fixedly connected to the output end of the servo motor 65. A square groove 67 is also opened on the top of the connecting plate 3. A gear ring 68 is rotatably installed on the middle of the outer side of the cylinder 61.

[0059] The drive tooth 66 passes through the square groove 67 and meshes with both gear rings 68. A connecting rod 69 is fixedly connected to the inner side of the gear ring 68. An impeller 610 is fixedly connected to the side of the connecting rod 69 away from the gear ring 68. The two impellers 610 are installed in opposite directions.

[0060] Example 2: Figure 11 - Figure 13 As shown, the reservoir 4 is filled with nursing fluid. The breather valve 7 is used to maintain the air pressure balance inside the reservoir 4. The servo motor 65 drives the drive gear 66 to rotate. The drive gear 66 drives the gear rings 68 on both sides to rotate. The two gear rings 68 rotate in the same direction. The gear rings 68 drive the connecting rod 69 to rotate. The connecting rod 69 drives the impeller 610 to rotate. The two impellers 610 are installed in opposite directions.

[0061] One impeller 610 rotates forward, drawing nursing fluid from the storage tank 4 through the cylinder 61. The nursing fluid enters the injection pipe 51 for subsequent injection operations. The other impeller 610 rotates in reverse, drawing the injected nursing fluid through the extraction pipe 52. The extracted and returned nursing fluid is discharged into the external collection box through the discharge pipe 63, thus achieving stable input and injection of nursing fluid and synchronous extraction and recovery.

[0062] Working principle: When using this device, firstly, as... Figure 1 - Figure 13As shown, medical staff first loosen the clamping bolt 55, pull the adjusting cover 54 to rotate, and the adjusting cover 54 drives the clamping bolt 55 to rotate, so that the injection head 56 is aligned with the wound area. Then, tighten the clamping bolt 55 to limit the vertical axis 53, so as to facilitate the angle adjustment of the adjusting cover 54 and the injection head 56. Next, the mounting cover 1 is placed inside the patient's mouth, and the patient bites the mounting cover 1 with their teeth. The blocking plate 2 blocks the patient's mouth. The servo motor 65 works to drive the drive gear 66 to rotate. The impeller 610 on one side rotates forward and draws nursing fluid from the reservoir 4 through the cylinder 61. The nursing fluid enters the injection tube 51. The impeller 610 on the other side rotates in reverse and draws the injected nursing fluid through the extraction tube 52. The nursing fluid drawn back is discharged into the external collection box through the discharge tube 63. The nursing fluid in the injection tube 51 flows into the two injection heads 56 and is injected into the wound area through the injection heads 56. By activating the two electric push rods 58, the wound area is retracted. Push rod 58 drives fixed block 59 to move, fixed block 59 drives connecting block 510 and injection head 56 to move, the two injection heads 56 move closer to each other, slowly increasing the injection flow rate of injection head 56, and the movement of toothed plate 511 drives gear 514 to rotate, gear 514 drives horizontal shaft 513 and main pulley 515 to rotate, main pulley 515 drives the driven pulley on the outside of rotating cylinder 519 to rotate through toothed belt 516, thereby driving rotating cylinder 519 to rotate, rotating cylinder 519 drives turntable 521 to rotate, and when injection head 56 moves to the maximum distance, rotating cylinder 519 and turntable 521 rotate forty-five degrees, and adapt to increase the extraction flow rate of extraction tube 52, adapt to different areas of wound to adjust injection flow rate, avoid wound area damage caused by excessive injection flow rate, and efficiently clean the residue in the edge area, and can also independently adapt to adjust the extraction flow rate of nursing solution after injection, reducing the soaking damage of nursing solution residue to wound.
