Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of medical devices, and particularly to a multifunctional dental treatment cart. Background Art
[0002] The multifunctional dental treatment cart is an indispensable device in dental diagnosis and treatment, with a variety of practical functions, which greatly facilitates the work of dentists. The dental cart is designed with multiple drawers and compartments, facilitating dentists to neatly store various dental tools and materials. In this way, during the treatment process, dentists can quickly find the required tools, improving work efficiency. At the same time, reasonable storage also helps to keep the tools clean and hygienic, reducing the risk of cross-infection. The design of the cart enables it to serve as a temporary workbench, facilitating dentists to access tools and materials at any time during the treatment process.
[0003] Clinically, the original design intention of the dental cart is to facilitate dentists to obtain various dental tools to assist in their daily treatment work. However, currently, the design functions of the dental cart do not have the function of recycling the stagnant cleaning water in the dental chair. Specifically, clinically, dental chairs usually have multiple functions. Generally, dental chairs are equipped with a saliva aspirator, a high-speed handpiece connector, and other components. Among them, each time the dental chair is turned on and used, the high-speed handpiece connector is needed to pump out the stagnant cleaning water in the dental chair. Otherwise, bacteria will breed due to the stagnant cleaning water, and cross-infection is likely to occur during treatment.
[0004] In the prior art, most dentists use a flip-top trash can or a simple collection bucket made of a waste plastic cylinder. The collection bucket is provided with a collection cavity. Medical staff hold the high-speed handpiece connector and insert it into a pre-opened hole in the collection bucket, allowing the stagnant cleaning water in the dental chair to flow into the collection bucket. During this process, when the high-speed handpiece connector is inserted into the hole and enters the collection bucket to contact the already collected cleaning liquid, the high-speed handpiece connector is easily infected by the bacteria bred in the water already collected in the collection bucket. When the high-speed handpiece connector is taken out for treatment operations, it is likely to cause bacterial cross-infection in the patient's oral cavity, bringing secondary harm to the patient. In addition, when the collection bucket is full, medical staff still have to move it to the disposal room for dumping and cleaning and disinfection. On the one hand, it is inconvenient to exert force to move it, and it is easy to shake and splash when moving. On the other hand, generally only disinfectant is used to rinse and disinfect it, and there are still dead corners on its inner wall that are not cleaned properly, with residual bacteria. Once the quick-connect head is inserted into the hole, cross-infection is likely to occur. Summary of the Invention
[0005] The purpose of the present invention is to provide a multifunctional dental treatment cart to solve the problems raised in the above background art.
[0006] To achieve the above purpose, the present invention provides the following technical solution: A multifunctional dental treatment cart, including a vehicle body, and a detachable recycling bucket is provided on the vehicle body;
[0007] It further includes a linkage rod extending into the recycling bin and a baffle plate sleeved on the outer wall of the linkage rod and capable of tilting and swinging with the linkage rod as the swing center. The upper end face of the baffle plate is a receiving surface, and a thin rubber ring is provided at the edge of the baffle plate. The thin rubber ring divides the recycling bin into two independent upper and lower spaces. The thin rubber ring selectively contacts the inner wall of the return bin to control whether the lower independent space in the recycling bin is communicated with the outside;
[0008] A cleaning member, the cleaning member includes an elastic connecting rod fixed to the side of the bottom end of the linkage rod and a longitudinal rod fixed to the end of the elastic connecting rod. The elastic connecting rod is attached to the inner bottom wall of the recycling bin, and the longitudinal rod is attached to the inner radial side wall of the recycling bin;
[0009] When the elastic connecting rod bends and deforms away from the linkage rod, the contact force between it and the inner wall of the recycling bin increases, and the contact force between the longitudinal rod and the inner radial side wall of the recycling bin increases synchronously. The linkage rod rotates and adjusts, and the elastic connecting rod and the longitudinal rod move in a circular motion trajectory to scrape and clean the inner bottom wall and the radial side wall of the recycling bin.
[0010] In a further embodiment, it further includes a drainage cover covering the upper opening of the recycling bin. The upper opening of the recycling bin is provided with an enlarged end with an arc-shaped structure, and the bottom end of the outer wall of the drainage cover is attached to the surface of the enlarged end;
[0011] The drainage cover is gradually bent and narrowed towards the center inside the drainage cover from top to bottom, forming a closed and narrowed end. The closed and narrowed end is provided with an insertion hole for the linkage rod to penetrate.
[0012] In a further embodiment, the drainage cover has a plurality of drainage holes for injecting recycled liquid into the recycling bin;
[0013] The drainage holes are distributed on the radial side wall of the drainage cover, and the drainage holes extend obliquely downward towards the center of the drainage cover.
[0014] In a further embodiment, a spherical support block is provided at a position of the linkage rod closer to the upper part. The upper end face of the baffle plate bulges upward to form a spherical structure. A hollow rotating seat is fixed at the center position of the receiving surface. The hollow rotating seat has open structures at both the upper and lower parts and is rotatably sleeved on the spherical support block. The hollow rotating seat can swing up and down on the outer wall of the spherical support block.
[0015] In a further embodiment, when the baffle plate is horizontally distributed, the thin rubber ring contacts the inner side wall of the recycling bin, and the upper and lower two spaces are independently distributed;
[0016] When the baffle plate receives the liquid injected from the drainage holes, the baffle plate swings due to uneven force, and a gap is generated between the thin rubber ring and the recycling bin. The upper and lower two independent spaces are communicated, and the recycled liquid flows from the upper independent space into the lower independent space.
[0017] In a further embodiment, the linkage rod includes an upper rod and a lower rod. The upper rod rotates through the drainage cover and enters the recovery barrel. The lower rod is located inside the recovery barrel, and a sliding sleeve is fixed at the top end. The bottom end of the upper rod extends into the sliding sleeve and a limiting disc is fixed.
[0018] An upwardly curved elastic connecting rod is fixed between the sliding sleeve and the longitudinal rod. An L-shaped connecting rod is fixed at a position near the bottom end of the outer wall of the upper rod, and a C-shaped clamping seat pressing on the elastic connecting rod is fixed at the bottom end of the L-shaped connecting rod.
[0019] In a further embodiment, cleaning wiping sleeves are fixedly sleeved on the outer walls of both the elastic connecting rod and the longitudinal rod.

During the recycling process, it can also prevent contamination when the quick-connect head is inserted into the barrel and prevent the splashing of cleaning liquid during the recycling process, facilitating clinical treatment by dental doctors and meeting the needs of dental clinical use.
[0025] 2. When the elastic connecting rod of the present invention bends and deforms towards the side away from the linkage rod, the contact force between it and the inner wall of the recovery barrel increases, and the contact force between the longitudinal rod and the radial side wall inside the recovery barrel increases synchronously. The linkage rod rotates and adjusts, and the elastic connecting rod and the longitudinal rod move in an annular motion trajectory, scraping and cleaning the inner bottom wall and the radial side wall of the recovery barrel more thoroughly.

[0039] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0040] Embodiment. This embodiment provides a multi-functional dental treatment vehicle, including a vehicle body 1, and a detachable recycling bin 2 is provided on the vehicle body 1, as Figure 1 and Figure 2As shown in the figure, a recessed groove 11 for placing the recycling bucket 2 is provided on the upper end surface of the vehicle body 1. The recycling bucket 2 has a cylindrical structure. The recycling bucket 2 is vertically lowered from the upper opening of the recessed groove 11 and is seated on the vehicle body 1 for recycling the cleaning liquid remaining in the dental chair. A handle is provided on the upper edge side wall of the recycling bucket 2. When the recycling amount in the recycling bucket 2 is about to be full, the medical staff can hold the handle and lift the recycling bucket 2 upward, pull it out of the recessed groove 11, pour out the recycled liquid and disinfect it for reuse.
[0041] As Figure 3 、 Figure 5 and Figure 6 shown, it also includes a linkage rod extending into the recycling bucket 2 and a baffle plate 7 sleeved on the outer wall of the linkage rod and capable of tilting and swinging with the linkage rod as the swing center. Specifically, the upper end surface of the baffle plate 7 is a receiving surface, and the receiving surface is the receiving side wall for the cleaning liquid ejected from the quick-connect body of the dental chair. A thin rubber ring 71 is provided on the edge of the baffle plate 7. The thickness of the thin rubber ring 71 is only 1-2 mm and is made of medical soft silicone with a soft texture. When the side wall of the edge of the thin rubber ring 71 contacts the inner wall of the recycling bucket 2, it can fit well with the inner wall, thereby dividing the recycling bucket 2 into two independent upper and lower spaces. The upper space is used to receive the cleaning liquid ejected from the quick-connect body of the dental chair, and the lower space is for the temporarily stored and hermetically recycled cleaning liquid to avoid communicating with the outside, so as to prevent the smell of the cleaning liquid from escaping and affecting the air quality of the consulting room.
[0042] By selectively contacting the thin rubber ring 71 with the inner wall of the recycling bucket, it is used to control whether the lower independent space in the recycling bucket 2 communicates with the outside, and thus control whether the cleaning liquid is received into the lower independent space. Specifically, as Figure 7 shown, a spherical support block 35 is provided at a position above the linkage rod. The upper end surface of the baffle plate 7 bulges upward to form a spherical structure. A hollow rotating seat is fixed at the center position of the receiving surface. The hollow rotating seat has open structures at both the upper and lower ends and is rotatably sleeved on the spherical support block 35. The hollow rotating seat can swing up and down on the outer wall of the spherical support block 35. Specifically, under normal conditions, when the baffle plate 7 is horizontally distributed, the thin rubber ring 71 contacts the inner side wall of the recycling bucket 2, and the upper and lower spaces are independently distributed. It is used to block the communication between the lower space and the outside and prevent strange smells from escaping from the recycling bucket 2. When the baffle plate 7 receives the cleaning liquid injected from the drainage hole 61, the baffle plate 7 swings due to uneven force, and a gap is generated between the thin rubber ring 71 and the recycling bucket 2, and the upper and lower independent spaces communicate, and the recycled liquid flows from the upper independent space into the lower independent space.
[0043] When the recycling bucket 2 is full, the recycling bucket 2 is pulled out of the recessed groove 11, the recycled cleaning liquid is poured out, and the inner wall of the bucket is cleaned.
[0044] Therefore, a cleaning part is also disclosed in this embodiment. As Figure 3 、 Figure 4 and Figure 5As shown in the figure, the cleaning member includes an elastic connecting rod 81 fixed to the side of the bottom end of the linkage rod and a longitudinal rod 82 fixed to the end of the elastic connecting rod 81. The elastic connecting rod 81 is in contact with the inner bottom wall of the recycling bin 2, and the longitudinal rod 82 is in contact with the inner radial side wall of the recycling bin 2. Cleaning wiping sleeves 8 are fixedly sleeved on the outer walls of both the elastic connecting rod 81 and the longitudinal rod 82. At the same time, the linkage rod includes an upper rod 3 and a lower rod 31. The upper rod 3 rotates through the drainage cover 6 and enters the recycling bin 2. The lower rod 31 is located inside the recycling bin 2, and a sliding sleeve 34 is fixed to the top end. The bottom end of the upper rod 3 extends into the sliding sleeve 34 and a limit disk is fixed. An upwardly curved elastic connecting rod 32 is fixed between the sliding sleeve 34 and the longitudinal rod 82. An L-shaped connecting rod is fixed at a position near the bottom end of the outer wall of the upper rod 3, and a C-shaped clamping seat 33 pressing on the elastic connecting rod 32 is fixed to the bottom end of the L-shaped connecting rod.
[0045] When cleaning the inner wall of the recycling bin 2, first pour out the recycled cleaning liquid, then inject clean disinfectant water into the bin, and then insert the elastic connecting rod 81 and the longitudinal rod 82 into the recycling bin 2. Here, there are two elastic connecting rods 81 and longitudinal rods 82 respectively. As Figure 3 shown, the inner bottom wall of the recycling bin 2 is a spherical structure. Here, the elastic connecting rod 81 is a quarter-circular structure. When cleaning the barrel wall, manually press the upper rod 3. Here, a circular operation disk is provided at the top end of the upper rod 3 to facilitate gripping and pressing down the upper rod 3, so that the limit disk at the bottom end of the upper rod 3 slides down along the inside of the sliding sleeve 34. While sliding down, the L-shaped connecting rod can be used to drive the C-shaped clamping seat 33 to press down the elastic connecting rod 32, so that the elastic connecting rod 32 can be straightened and deformed, and then the elastic connecting rod 81 can be bent and deformed towards the side away from the linkage rod, increasing the contact force between it and the inner wall of the recycling bin 2. At the same time, the longitudinal rod 82 is driven to further press against the inner radial side wall of the recycling bin 2, and the contact force between it and the inner radial side wall of the recycling bin 2 increases synchronously. Since the C-shaped clamping seat 33 is stuck on the elastic connecting rod 32, when the upper rod 3 is rotated, the lower rod 31, the elastic connecting rod 32, the longitudinal rod 82 and the elastic connecting rod 81 can be driven to make a circular motion. The circular motion trajectories of the elastic connecting rod 81 and the longitudinal rod 82 can use the cleaning wiping sleeves 8 to scrape and clean the inner bottom wall and the radial side wall of the recycling bin 2.
[0046] The purpose of the above design is that the inner wall of the recycling bin 2 has a relatively deep depth. When cleaning the inner wall, it is not convenient for the cleaning personnel to apply force horizontally to wipe the inside of the barrel. Then, by applying force horizontally, with the deformation of the elastic connecting rod 81, the cleaning wiping sleeve 8 on the outer wall of the elastic connecting rod 81 is driven to closely fit the inner bottom wall of the barrel, and at the same time, the cleaning wiping sleeve 8 on the outer wall of the longitudinal rod 82 is closely fit with the inner radial side wall of the barrel. As long as the cleaning wiping sleeve 8 makes a circular motion, the inner wall of the barrel can be better cleaned.
[0047] As Figure 3 and Figure 4As shown, it further includes a drainage cover 6 covering the upper opening of the recycling bin 2. The upper opening of the recycling bin 2 is provided with an enlarged end having an arc-shaped structure. The bottom end of the outer wall of the drainage cover 6 is attached to the surface of the enlarged end. The purpose of the drainage cover 6 is to facilitate the quick-connect head to align with the inner space thereof without contacting its inner wall. The drainage cover 6 is gradually curved and narrowed from top to bottom towards the center inside the drainage cover 6 to form a closed and narrowed end for accommodating and receiving the injected cleaning liquid. The structure of the drainage cover 6 is as shown in Figure 4 When the cleaning liquid is injected, the cleaning liquid flows down along its arc-shaped inner wall, and it is not easy to generate splashing phenomenon.
[0048] The cleaning liquid is injected into the drainage cover 6. The drainage cover 6 has a plurality of drainage holes 61. Here, the drainage holes 61 are distributed on the radial side wall of the drainage cover 6 and are injected into the recycling bin 2 through the drainage holes 61. The closed and narrowed end is provided with an insertion hole for the linkage rod to pass through. The drainage holes 61 are inclined and extended towards the lower part near the center of the drainage cover 6. The purpose of this move is, on the one hand, to facilitate the injected cleaning liquid to enter the upper independent space through the drainage holes 61. On the other hand, it avoids the cleaning liquid injected into the recycling bin 2 from splashing out of the drainage holes 61 and splashing back into the drainage cover 6 in the reverse direction, attaching to the quick-connect head inserted into the drainage cover 6, resulting in the surface of the quick-connect head being contaminated, and when treating patients, it is easy to generate the risk of cross-infection.
[0049] Meanwhile, in this embodiment, a plurality of drawers 4 that can be pulled out are provided on multiple side walls of the vehicle body 1 for classifying and storing dental instruments. Specifically, as shown in Figure 2 As shown, the vehicle body 1 is provided with pull-out grooves having an isosceles trapezoid structure on three circumferential side walls, and the three pull-out grooves at the same height are interconnected. Then, the three drawers 4 at the same height are distributed at the positions as shown in Figure 10 As shown. The three drawers 4 are adjacent to each other, without affecting the vertically opened recessed grooves 11 on the vehicle body 1, and the space utilization rate is relatively high. At the same time, the design method of using a plurality of small-sized drawers 4 is adopted. Since most of the dental instruments are of small-sized structures, such as mouth mirrors, probes, forceps, disposable cups, cotton swabs, cotton wool, etc., using a plurality of small-sized drawers 4 is convenient for classifying and storing the above items.
[0050] It further includes a base 5 rotatably installed on the bottom wall of the vehicle body 1. As shown in Figure 8 and Figure 9 As shown, specifically, a rotating column 12 having an inverted T-shaped structure is fixed to the bottom wall of the vehicle body 1. A matching groove for rotatably engaging with the rotating column 12 is provided on the upper end surface of the base 5. The dental doctor can manually rotate the vehicle body 1, and the vehicle body 1 can rotate on the upper end surface of the base 5. When the vehicle body 1 rotates on the base 5, it can adjust the distribution orientation of the drawers 4 on different side walls relative to the dental doctor. In this way, when the dental doctor performs clinical treatment, it is more convenient to open the side drawers 4 without having to lean over or stand up to change the body position.
[0051] What needs to be further limited here is that during the movement of the drawer 4, it may be pulled out along the sliding groove due to vibration, occupying the lateral space, or even completely sliding out and falling. Therefore, a limiting sliding groove 13 is opened on the inner bottom wall of the sliding groove, and at the same time, an elastic limiting hook 41 is fixed on the bottom wall of the drawer 4. As shown in Figure 9 、 Figure 11 and Figure 12 . When installing the drawer 4, push the drawer 4 horizontally deeper along the sliding groove. The elastic limiting hook 41 is hard-pressed by the inner bottom wall of the sliding groove and deforms towards the bottom wall of the drawer 4. When the elastic limiting hook 41 slides to the limiting sliding groove 13, it returns to its initial state. Without a strong hard pull on the drawer 4, the elastic limiting hook 41 will not easily be pulled out of the limiting sliding groove 13. Such a design can prevent the drawer 4 from sliding out of the sliding groove horizontally during the movement.
[0052] Moreover, a limiting convex block 14 is provided at one end of the inner bottom wall of the limiting sliding groove 13 away from the notch of the sliding groove. When the drawer 4 is completely pushed into the sliding groove, the elastic limiting hook 41 can cross the limiting convex block 14 and be stuck on the side wall of the limiting convex block 14 away from the notch of the sliding groove. The purpose of this design is to completely limit the drawer 4 in the sliding groove, avoiding the drawer 4 sliding open randomly along the sliding groove due to vibration during the movement of the vehicle, thereby avoiding occupying the lateral space, touching the corridor, the indoor wall, or hitting the patient.
[0053] At the same time, in order to conveniently move and adjust the use position of the entire vehicle according to the use requirements, as shown in Figure 1 、 Figure 9 , a brake universal wheel can be rotatably installed at the corner of the bottom wall of the vehicle body 1 on the bottom base 5. The brake universal wheel facilitates the easy movement of the entire vehicle.
[0054] In summary, the entire vehicle body 1 combines clinical treatment problems, integrating functions such as recycling and cleaning water, preventing odor backflow, facilitating the cleaning of the inner wall of the recycling bucket 2, and classifying and storing dental instruments. During the recycling process, it can also prevent contamination when the quick-connect head of the dental chair is inserted into the bucket and prevent the splashing of cleaning liquid during the recycling process, facilitating the clinical treatment of dentists and meeting the clinical use requirements of dentistry.
