Description

Technical Field

[0001] The invention relates to the field of medical instruments, and in particular to a comprehensive oral treatment chair. Background Art

[0002] A dental comprehensive treatment chair is a device used in dental medical treatment, which can provide a variety of treatment functions, including teeth cleaning, filling, tooth extraction, root canal treatment, etc. This chair usually has adjustable height and angle to meet the needs of different patients.

[0003] After searching in the publication (announcement) number: CN111658415B, a mechanically controlled comprehensive dental treatment chair is disclosed, including a base frame, a seat frame is slidably connected to the upper side of the base frame, and lifting screws are slidably provided on both sides of the seat frame, the lower ends of the lifting screws are fixedly connected to the base frame, and both sides of the seat frame are rotatably connected to bevel gears 1 whose middle parts are threadedly connected to the lifting screws; a drive shaft is rotatably connected in the seat frame, and the drive shaft is fixedly connected to drive gear 1, a seat plate is slidably connected to the upper side of the seat frame, and a fixed frame is fixedly connected to the lower side of the seat plate, and a movable shaft 1 is rotatably connected to the lower end of the fixed frame, and both ends of the movable shaft 1 are fixedly connected to bevel gear 2, and the movable shaft 1 is fixedly connected to drive gear 2; the seat frame is fixedly connected to a push spring which can push the fixed frame to move upward under normal conditions until bevel gear 2 is meshed with bevel gear 1, and at the same time, drive gear 2 is meshed with drive gear 1.

[0004] Although the above solution can achieve the adjustment of the treatment chair, the patient's mouth will inevitably produce a large amount of saliva during dental treatment. Due to the excessive secretion of saliva, it may interfere with the clarity of the visual field of the treatment operation and affect the treatment effect. Therefore, it is usually necessary to equip a special saliva adsorption device to deal with this problem. However, many adsorption devices currently have a common defect, that is, they cannot effectively control the adsorption speed. This situation can easily cause patients to feel uncomfortable during treatment, such as damage to the oral mucosa due to excessive suction or nausea. Summary of the invention

[0005] The main purpose of the present invention is to provide a comprehensive oral treatment chair, which solves the problem that the adsorption speed cannot be effectively controlled, which easily causes the patient to feel uncomfortable during the treatment process, such as damage to the oral mucosa or nausea due to excessive suction, by providing a saliva suction mechanism, a control mechanism and a purification mechanism.

[0006] To achieve the above object, the technical solution adopted by the present invention is:

[0007] A comprehensive oral treatment chair, comprising:

[0008] The seat body has a collecting tank and a purification box disposed on one side of the seat body in sequence, and the interior of the collecting tank is connected to the interior of the purification box through a vacuum pump;

[0009] The purification mechanism includes a plurality of parallel partitions arranged on the inner side wall of the purification box, and activated carbon placed on the top of the partitions for purifying the air, each of the partitions is provided with a through hole on the top, and the through holes on any two adjacent partitions are staggered;

[0010] The positioning mechanism includes a driving member connected to the seat body, and two sets of clamping plates movably arranged on the top plate of the seat body for fixing the head;

[0011] The saliva suction mechanism includes an electric telescopic rod fixedly connected to the outer side wall of the clamping plate, a bearing frame fixedly connected to the output end of the electric telescopic rod, and a suction head movably arranged on the top of the bearing frame for sucking saliva, wherein the suction head is connected to the interior of the collection tank through a telescopic hose;

[0012] The control mechanism includes a fixing ring fixedly connected to the outer wall of the adsorption head, a limiting rod and a distance measuring sensor fixedly connected to the inner top wall of the fixing ring, and a floating plate sleeved on the outer wall of the limiting rod.

[0013] Preferably, the purification mechanism further comprises an upper air outlet pipe and a lower air outlet pipe fixedly connected to the outer side wall of the purification box, and a guide plate fixedly connected to one of the partition side walls, and the projection of the upper air outlet pipe can be projected onto the outer surface of the guide plate.

[0014] Preferably, the purification mechanism also includes two sets of parallel sealing plates fixedly connected to the inner wall of the purification box, a movable shaft movably arranged on the inner wall of the through hole, and a first movable plate fixedly connected to the outer wall of the movable shaft, and the first movable plate will face the upper air outlet pipe.

[0015] Preferably, the purification mechanism further comprises a second movable plate fixedly connected to the outer side wall of the movable shaft, the second movable plate and the first movable plate are distributed along two specific points on the outer surface of the movable shaft, and the angle between the two specific points is ninety degrees.

[0016] Preferably, the saliva suction mechanism also includes a permanent magnetic rod and an annular sleeve fixedly connected to the inner side wall of the carrying frame, a knob penetrating the side wall of the carrying frame and rotatably connected to the side wall, and a magnetic isolation block fixedly connected to the side of the knob close to the permanent magnetic rod, the annular sleeve is sleeved on the outer surface of the permanent magnetic rod, and the magnetic isolation block is located between the annular sleeve and the permanent magnetic rod, and the annular sleeve is composed of four arc-shaped blocks connected end to end.

[0017] Preferably, the saliva suction mechanism further comprises a slider sleeved on the outer side wall of the annular sleeve, and a magnetic block adsorbed on the outer side wall of the slider.

[0018] Preferably, the driving member comprises a servo motor fixedly connected to the outer side wall of the seat body, a forward and reverse ball screw fixedly connected to the output end of the servo motor, and two sets of movable seats threadedly connected to the outer side wall of the forward and reverse ball screw;

[0019] The clamping plate is fixedly connected to the top of the movable seat, and the two groups of movable seats are symmetrically arranged with respect to the mid-vertical plane of the forward and reverse ball screws.

[0020] Preferably, a driving motor is fixedly connected to the inner wall of the collecting tank, and a stirring blade is fixedly connected to the outer wall of the output end of the driving motor.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. In the present invention, the servo motor is started to rotate forward, thereby driving the forward and reverse ball screws to rotate, thereby driving the two movable seats and the splint to move toward each other until the splint contacts the patient's head, thereby fixing the patient's head and facilitating the doctor's treatment.

[0023] 2. In the present invention, the slider is pushed and pulled to move it to a suitable position, that is, flush with the patient's mouth, and then the knob is turned to rotate it ninety degrees, thereby driving the magnetic isolation block to rotate and making the magnetic isolation block overlap with the magnetic isolation material of the annular sleeve. At this time, the permanent magnetic rod will adsorb the slider to fix the slider, and then the magnetic block is removed, and the adsorption head is placed in the groove of the slider. Finally, the magnetic block and the slider are adsorbed to fix the adsorption head, and finally the electric telescopic rod is contracted to plug the adsorption head into the patient's mouth. Because the position of the adsorption head is adjustable, it can be adapted to different patients, thereby improving the applicability of the device.

[0024] 3. In the present invention, by inserting the adsorption head into the patient's mouth and starting the vacuum pump, the interior of the collection tank is made to have a negative pressure. At this time, the saliva and blood in the patient's mouth will pass through the adsorption head and the telescopic hose in turn under the action of pressure and finally enter the interior of the collection tank. In this process, by starting the drive motor, the saliva is fully mixed with the disinfectant in the collection tank, which can effectively kill these pathogens and reduce the risk of infection between patients and medical staff. When there is a lot of blood in the patient's mouth, it will drive the float plate to move up until the distance measuring sensor detects that the distance of the float plate reaches the set value. At this time, the distance measuring sensor will increase the suction force of the vacuum pump, thereby increasing the adsorption force of the adsorption head to prevent excessive blood in the patient's mouth.

[0025] 4. In the present invention, by strengthening the suction of the vacuum pump, the air flows faster inside the purification box, thereby pushing the first movable plate and driving the movable shaft to rotate until the side of the first movable plate abuts against the inner wall of the purification box, so that the two sealing plates and the first movable plate seal the opening of the upper air outlet pipe. At this time, the second movable plate will rotate upward under the action of the movable shaft, thereby opening the through hole. At this time, the air will be discharged from the lower air outlet pipe, thereby extending the circulation time of the air inside the purification box, thereby avoiding the phenomenon of incomplete purification due to excessive air flow rate.

[0047] Embodiment 2

[0048] Please refer to Figure 1 - Figure 7 As shown, the present invention is a comprehensive oral treatment chair, comprising:

[0049] The seat body 1, a collecting tank 2 and a purification box 3 are sequentially arranged on one side of the seat body 1, and the interior of the collecting tank 2 is connected to the interior of the purification box 3 through a vacuum pump 201;

[0050] The purification mechanism includes a plurality of parallel partitions 301 arranged on the inner side wall of the purification box 3, and activated carbon placed on the top of the partitions 301 for purifying the air. A through hole is opened on the top of each partition 301, and the through holes on any two adjacent partitions 301 are staggered;

[0051] The positioning mechanism includes a driving member connected to the seat body 1 and two sets of clamping plates 404 movably arranged on the top plate of the seat body 1 for fixing the head;

[0052] The saliva suction mechanism includes an electric telescopic rod 501 fixedly connected to the outer wall of the clamping plate 404, a bearing frame 502 fixedly connected to the output end of the electric telescopic rod 501, and an adsorption head 503 movably arranged on the top of the bearing frame 502 for absorbing saliva, and the adsorption head 503 is connected to the interior of the collection tank 2 through a telescopic hose 504;

[0053] The control mechanism includes a fixed ring 601 fixedly connected to the outer wall of the adsorption head 503, a limit rod 602 and a distance sensor 604 fixedly connected to the inner top wall of the fixed ring 601, and a floating plate 603 mounted on the outer wall of the limit rod 602. The distance sensor 604 can control the adsorption force of the vacuum pump 201.

[0054] The saliva suction mechanism also includes a permanent magnetic rod 505 and an annular sleeve 506 fixedly connected to the inner wall of the supporting frame 502, a knob 507 that penetrates the side wall of the supporting frame 502 and is rotatably connected to the side wall, and a magnetic isolation block 508 fixedly connected to the knob 507 on the side close to the permanent magnetic rod 505. The annular sleeve 506 is sleeved on the outer surface of the permanent magnetic rod 505, and the magnetic isolation block 508 is located between the annular sleeve 506 and the permanent magnetic rod 505. The annular sleeve 506 is composed of four arc blocks connected end to end, and two arc blocks that are arranged opposite to each other are made of magnetic isolation material. The magnetic isolation block 508 is driven to rotate by the knob 507. The magnetic performance of the permanent magnetic rod 505 to the outside world can be controlled by the relative position (interlaced or overlapped) of the magnetic isolation block 508 and the magnetic isolation material of the annular sleeve 506.

[0055] The saliva suction mechanism also includes a slider 509 sleeved on the outer wall of the annular sleeve 506, and a magnetic block 5010 adsorbed on the outer wall of the slider 509, wherein the slider 509 is made of ferromagnetic material, and the adsorption head 503 is fixed by placing the adsorption head 503 in the groove of the slider 509 and snapping the magnetic block 5010 on the outer surface of the adsorption head 503.

[0056] The inner wall of the collection tank 2 is fixedly connected to a drive motor 202, and the outer wall of the output end of the drive motor 202 is fixedly connected to a stirring fan blade 203. By adding disinfectant to the interior of the collection tank 2 and then starting the drive motor 202, the saliva and the disinfectant are fully mixed, thereby effectively killing these pathogens and reducing the risk of infection between patients and medical staff.

[0057] When the patient's head is fixed, push and pull the slider 509 to move it to a suitable position, that is, flush with the patient's mouth, and then turn the knob 507 to rotate it ninety degrees, thereby driving the magnetic isolation block 508 to rotate and making the magnetic isolation block 508 overlap with the magnetic isolation material of the annular sleeve 506. At this time, the permanent magnetic rod 505 will adsorb the slider 509 to fix the slider 509, and then remove the magnetic block 5010, and place the adsorption head 503 in the groove of the slider 509, and finally adsorb the magnetic block 5010 and the slider 509 to fix the adsorption head 503, and finally retract the electric telescopic rod 501 to insert the adsorption head 503 into the patient's mouth. Through the above operations, the position of the adsorption head 503 can be adjusted to adapt to different patients.

[0058] When the doctor is treating the patient's oral cavity, the suction head 503 is inserted into the patient's mouth and the vacuum pump 201 is started, so that the interior of the collection tank 2 is under negative pressure. At this time, the saliva and blood in the patient's mouth will pass through the suction head 503 and the telescopic hose 504 in turn under the action of pressure, and finally enter the interior of the collection tank 2. In this process, the drive motor 202 is started to fully mix the saliva with the disinfectant in the collection tank 2, which can effectively kill these pathogens and reduce the risk of infection between patients and medical staff.

[0059] When there is a lot of blood and water in the patient's mouth, the float plate 603 will be driven to move upward until the distance sensor 604 detects that the distance of the float plate 603 reaches the set value. At this time, the distance sensor 604 will increase the suction of the vacuum pump 201, thereby increasing the adsorption force of the adsorption head 503 to prevent excessive blood and water in the patient's mouth. When there is less blood and water in the patient's mouth, the distance sensor 604 can reduce the suction of the vacuum pump 201 to avoid damage to the oral mucosa or nausea due to excessive suction.

[0060] Embodiment 3

[0061] Please refer to Figure 8 - Fig.10 As shown, the present invention is a comprehensive oral treatment chair, comprising:

[0062] The seat body 1, a collecting tank 2 and a purification box 3 are sequentially arranged on one side of the seat body 1, and the interior of the collecting tank 2 is connected to the interior of the purification box 3 through a vacuum pump 201;

[0063] The purification mechanism includes a plurality of parallel partitions 301 arranged on the inner side wall of the purification box 3, and activated carbon placed on the top of the partitions 301 for purifying the air. A through hole is opened on the top of each partition 301, and the through holes on any two adjacent partitions 301 are staggered;

[0064] The positioning mechanism includes a driving member connected to the seat body 1 and two sets of clamping plates 404 movably arranged on the top plate of the seat body 1 for fixing the head;

[0065] The saliva suction mechanism includes an electric telescopic rod 501 fixedly connected to the outer wall of the clamping plate 404, a bearing frame 502 fixedly connected to the output end of the electric telescopic rod 501, and an adsorption head 503 movably arranged on the top of the bearing frame 502 for absorbing saliva, and the adsorption head 503 is connected to the interior of the collection tank 2 through a telescopic hose 504;

[0066] The control mechanism includes a fixed ring 601 fixedly connected to the outer wall of the adsorption head 503, a limit rod 602 and a distance sensor 604 fixedly connected to the inner top wall of the fixed ring 601, and a floating plate 603 mounted on the outer wall of the limit rod 602. The distance sensor 604 can control the adsorption force of the vacuum pump 201.

[0067] The purification mechanism also includes an upper air outlet pipe 302 and a lower air outlet pipe 303 fixedly connected to the outer wall of the purification box 3, and a guide plate 308 fixedly connected to the side wall of a partition 301. The projection of the upper air outlet pipe 302 can be projected on the outer surface of the guide plate 308, and the guide plate 308 can change the direction of the wind so that it blows obliquely upward.

[0068] The purification mechanism also includes two sets of parallel sealing plates 304 fixedly connected to the inner wall of the purification box 3, a movable shaft 305 movably set on the inner wall of the through hole, and a first movable plate 306 fixedly connected to the outer wall of the movable shaft 305. The first movable plate 306 will face the upper air outlet pipe 302, wherein the distance between the two sealing plates 304 is definitely matched with the first movable plate 306. When the vacuum pump 201 delivers air into the purification box 3 at a faster flow rate, it will push the first movable plate 306 to drive the movable shaft 305 to rotate until the side of the first movable plate 306 abuts against the inner wall of the purification box 3, thereby allowing the two sealing plates 304 and the first movable plate 306 to seal the opening of the upper air outlet pipe 302.

[0069] The purification mechanism also includes a second movable plate 307 fixedly connected to the outer wall of the movable shaft 305. The second movable plate 307 and the first movable plate 306 are distributed along two specific points on the outer surface of the movable shaft 305, and the angle between the two specific points is ninety degrees. When the second movable plate 307 is in the initial position, a through hole can be sealed so that air is discharged from the upper air outlet pipe 302. When the movable shaft 305 rotates, the second movable plate 307 will be driven to rotate, thereby opening the through hole of the partition 301, so that the purified air will be discharged from the lower air outlet pipe 303.

[0070] The multiple groups of partitions 301 can extend the circulation time of air in the purification box 3, thereby improving the purification effect of the air. When the suction force of the vacuum pump 201 is weak, the air flow rate in the purification box 3 will not be able to drive the movable shaft 305 to rotate, so that the air will be discharged from the upper air outlet pipe 302. At this time, the direction of the air (such as Fig. 9 ) as indicated by the dotted line in ;

[0071] If the suction force of the vacuum pump 201 is strengthened, the air will flow faster inside the purification box 3, thereby pushing the first movable plate 306 and driving the movable shaft 305 to rotate until the side of the first movable plate 306 abuts against the inner wall of the purification box 3, so that the two sealing plates 304 and the first movable plate 306 seal the opening of the upper air outlet pipe 302. At this time, the second movable plate 307 will rotate upward under the action of the movable shaft 305, thereby opening the through hole, and the air will be discharged from the lower air outlet pipe 303 (the direction of the air at this time is as shown in FIG. Fig.10 The above operation can extend the circulation time of air in the purification box 3, thereby avoiding the phenomenon of incomplete purification caused by too fast flow rate.
