Description

Technical Field

[0001] This invention belongs to the field of oral care technology, specifically a nursing device that integrates saliva suction and moisture isolation during oral treatment. Background Technology

[0002] During oral diagnosis and treatment, especially clinical procedures such as teeth cleaning and dental treatment, saliva, waste fluid, tartar, and dental debris are continuously produced in the oral cavity. Timely suctioning of saliva and cleaning of debris are key steps to ensure the smooth progress of diagnosis and treatment.

[0003] Currently, the traditional saliva suction devices commonly used in clinical practice have relatively limited functions. During the procedure, the suction channel is easily blocked by large pieces of tartar and tooth debris. Once the channel is blocked, medical staff need to suspend treatment, manually disassemble the tubing, clean the blockage, and reposition it. This not only interrupts the treatment process and reduces operational efficiency, but also seriously affects the continuity of treatment. Summary of the Invention

[0004] The purpose of this invention is to provide an integrated nursing device for saliva suction and moisture isolation during oral treatment, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an integrated saliva suction and moisture isolation nursing device for oral treatment, comprising:

[0006] The base is installed on one side of the negative pressure suction component for opening support, and a baffle plate is provided on one side of the base;

[0007] The saliva suction and debris removal structure includes a sliding tube that is slidably disposed through a base for absorbing saliva; the saliva suction and debris removal structure is also provided with a reset component for resetting the sliding tube after debris removal and continuing to absorb saliva.

[0008] The chip removal assembly includes a chip removal rod disposed within a sliding tube for clearing debris that clogs one end of the sliding tube.

[0009] As a further preferred embodiment of this technical solution, the saliva suction and debris removal structure further includes: a saliva suction port, which is provided at one end of the sliding tube for suction, and is used to provide a suction channel for saliva; and a fixed tube, which is installed on the inner wall of the base, with the sliding tube sleeved on the outside of the fixed tube.

[0010] As a further preferred embodiment of this technical solution: a sealing gasket is provided at the sliding connection between the sliding tube and the fixed tube to ensure the sealing between the sliding tube and the fixed tube.

[0011] As a further preferred embodiment of this technical solution: the inner end of the fixing tube near the saliva inlet is designed with an inner cone shape to prevent fine particles inside from remaining at one end of the fixing tube during saliva suction.

[0012] As a further preferred embodiment of this technical solution, the saliva suction and debris removal structure further includes: a limiting groove, which is formed on both sides of the outside of the fixed tube and is used to limit the sliding tube, and the limiting block at one end of the sliding tube is slidably connected in the limiting groove; a reset spring, one end of which is connected to the negative pressure suction component and the other end of which is connected to the sliding tube; and a sealing quick connector, which is installed at the end of the fixed tube away from the sliding tube and is used to connect the negative pressure suction component.

[0013] As a further preferred embodiment of this technical solution: a fixed tube passes through one side of the base and is fixedly connected to a sealing quick-connect fitting, used to connect the negative pressure transmission hose of the negative pressure suction component.

[0014] As a further preferred embodiment of this technical solution, the chip removal assembly further includes: a support plate, which is fixedly arranged at one end inside the fixed tube to support the chip removal rod, and the chip removal rod is fixedly arranged on the support plate; and a chip collection cavity, which is opened inside the lower end of the base to collect larger particles of debris.

[0015] As a further preferred embodiment of this technical solution: several sets of saliva suction ports and several sets of chip removal rods are provided, and each set of chip removal rods corresponds to a saliva suction port.

[0016] As a further preferred embodiment of this technical solution: the diameter of the chip removal rod is smaller than the diameter of the saliva suction port.

[0017] As a further preferred embodiment of this technical solution, the support plate is configured with a cross structure.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. In this invention, the functions of suctioning, chip removal, and repositioning are integrated into an integrated suction and chip removal mechanism. The negative pressure difference automatically triggers the clearing action. When tartar or tooth debris blocks the suction channel, the chip removal and repositioning are completed automatically without manual intervention. This avoids tube blockage from the root cause, ensures continuous and unobstructed suction during the operation, and significantly improves the continuity of diagnosis and treatment and operational efficiency.

[0020] 2. In this invention, the base integrates functions of mouth opening support, cheek retraction, and tongue blocking and moisture isolation. It is disposable and can be operated by a single person without the need for additional cotton rolls or rubber barriers, thus reducing the cost of medical staff cooperation. The flexible and fitting design reduces the feeling of foreign objects in the mouth and the nausea reflex, improving the patient's comfort and cooperation during treatment.

[0021] 3. Fine saliva and waste liquid enter the negative pressure saliva collection cylinder through the tube, while large pieces of tartar and debris automatically fall into the base debris collection cavity for centralized collection, achieving solid-liquid separation. This prevents large pieces of debris from entering the negative pressure main unit and causing malfunctions, while also reducing debris backflow and diffusion, effectively reducing the risk of cross-infection, ensuring the surgical area is dry and clean, and improving the quality of treatment.

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0036] like Figures 1 to 7 Schematic diagrams of some embodiments of the integrated saliva suction and moisture-proof nursing device provided in this application.

[0037] In some embodiments, the integrated saliva suction and moisture-proof nursing device can be an integrated saliva suction and moisture-proof device, a rubber dam integrated device, a portable foldable nursing device, or an orthodontic-specific nursing device. Among them, the integrated saliva suction and moisture-proof device can be, but is not limited to, a disposable base type, a reusable modular type, a flexible split type, or an aerosol-resistant reinforced type. Figure 1 In this embodiment, a disposable base-type saliva suction and moisture-proof integrated nursing device is used as an example for description. Of course, other types of saliva suction and moisture-proof integrated nursing devices can also adopt a similar structure, which will not be described in detail below.

[0038] Understandable Figure 1 The illustration only shows some of the components of the integrated saliva suction and moisture-proof nursing device. The actual shape, size, location, and construction of these components are not subject to change. Figure 1 Due to limitations, integrated saliva suction and moisture-proof nursing devices can also include, compared to... Figure 1 More or fewer parts.

[0039] In some embodiments, the integrated saliva suction and moisture isolation device may include a negative pressure suction component 1 and a base 2. The base 2 may be detachably connected to the negative pressure suction component 1. For example, when the integrated saliva suction and moisture isolation device is a disposable base 2 type integrated saliva suction and moisture isolation device, the base 2 may be a disposable medical rigid / soft plastic substrate, and the negative pressure suction component 1 may be a component that integrates negative pressure suction and saliva storage.

[0040] For example, the integrated saliva suction and moisture isolation nursing device may also include a tongue guard 5, which can be installed at the front end of the base 2 to isolate, protect and isolate the tongue in the oral cavity.

[0041] The negative pressure suction assembly 1 consists of a mobile vehicle, a negative pressure saliva pump, a saliva collection container, hoses, a pressure gauge, and a controller. The mobile vehicle is used to carry and move the various functional components, allowing for flexible placement in the examination room. The negative pressure saliva pump provides negative pressure power to the system and is connected to the base 2 via hoses to transport and collect saliva, waste liquid, and small debris. The saliva collection container is used to temporarily store waste liquid to prevent backflow and contamination. The pressure gauge displays the negative pressure value of the pipeline in real time, allowing medical staff to monitor the suction force. The controller is used to start and stop the negative pressure saliva pump and adjust the negative pressure level to adapt to different treatment scenarios and patient tolerance, ensuring a stable and safe saliva suction process.

[0042] Among them, when the integrated saliva suction and moisture isolation nursing device is a disposable base 2 type integrated saliva suction and moisture isolation device, the base 2 can be a U-shaped occlusal support base 2, which has the functions of mouth opening support, cheek retraction and surgical area moisture isolation.

[0043] Among them, the tongue plate 5 can be a flexible silicone tongue plate 5, an arc-shaped tongue plate 5, a hollow tongue plate 5, etc.

[0044] In some embodiments, the following are included:

[0045] The saliva suction and debris removal structure includes a sliding tube 301 that is slidably disposed within the base 2 for absorbing saliva; the saliva suction and debris removal structure is also provided with a reset component for resetting the sliding tube 301 after debris removal and for continuing to absorb saliva.

[0046] The chip removal assembly includes a chip removal rod 401 arranged inside the sliding tube 301 for cleaning debris that is blocked at one end of the sliding tube 301.

[0047] In this process, after the base 2 is placed in the cavity and clamped, the negative pressure suction component 1 is activated. The negative pressure generated by the negative pressure suction component 1 is transmitted to the sliding tube 301 through the hose. The negative pressure of the sliding tube 301 suctions the saliva produced in the mouth. When the saliva contains large debris, it blocks the sliding tube 301, thus forming a seal inside the sliding tube 301. The continuous suction of the negative pressure drives the sliding tube 301 to slide to one side on the base 2. When the sliding tube 301 contacts the chip removal rod 401, the debris blocking one side of the sliding tube 301 is cleared.

[0048] In this embodiment, the sliding tube 301 is moved to one side to contact the chip removal rod 401 to clean the debris by blocking it. When the debris is pushed out by the chip removal rod 401, the suction force of the negative pressure on the debris decreases, and the debris falls off by its own weight. The cleaned sliding tube 301 automatically resets, thereby preventing larger debris from clogging the negative pressure suction component 1, and can automatically collect larger debris to maintain the continuity of saliva suction.

[0049] It should be noted that debris includes, for example, tartar and tooth debris.

[0050] In some embodiments, the saliva suction and debris removal structure further includes: a saliva suction port 302, which is provided at one end of the sliding tube 301 for suction, and is used to provide a suction channel for saliva; and a fixed tube 303, which is installed on the inner wall of the base 2, and the sliding tube 301 is sleeved on the outside of the fixed tube 303.

[0051] When the sliding tube 301 draws saliva through the negative pressure suction component 1, the saliva enters the sliding tube 301 through the suction port 302 and then enters the fixed tube 303. When the saliva contains large particles, it can cause blockage of the suction port 302. The negative pressure suction of the negative pressure suction component 1 causes the sliding tube 301 to slide to one side outside the fixed tube 303, and at the same time, it brings the adsorbed debris into the base 2.

[0052] In this embodiment, the sliding tube 301 is sealed by blocking the saliva inlet 302 with a blockage material, thereby moving the sliding tube 301 through negative pressure to self-clean larger debris.

[0053] It should be noted that a sealing gasket is provided at the sliding connection between the sliding tube 301 and the fixed tube 303 to ensure the sealing between the sliding tube 301 and the fixed tube 303.

[0054] The fixed tube 303 has an inner conical shape at the end near the saliva inlet 302 to prevent small particles from remaining at the end of the fixed tube 303 during saliva suction.

[0055] In some embodiments, the saliva suction and debris removal structure further includes: a limiting groove 304, which is formed on both sides of the outside of the fixed tube 303, for limiting the sliding tube 301, and the limiting block at one end of the sliding tube 301 is slidably connected in the limiting groove 304; a reset spring 305, one end of which is connected to the negative pressure suction component 1, and the other end of which is connected to the sliding tube 301; and a sealing quick connector 306, which is installed at the end of the fixed tube 303 away from the sliding tube 301, for connecting the negative pressure suction component 1.

[0056] In this process, the blocked sliding tube 301 slides on the limiting groove 304 and compresses the reset spring 305.

[0057] In this embodiment, the sliding tube 301 is kept in a horizontal moving state during the movement by setting the limiting groove 304, and the negative pressure of the sliding tube 301 compresses the reset spring 305, which facilitates the subsequent reset of the sliding tube 301.

[0058] It should be noted that the fixed tube 303 passes through one side of the base 2 and is fixedly connected to the sealing quick connector 306, which is used to connect the negative pressure transmission hose of the negative pressure suction assembly 1.

[0059] One end of the negative pressure hose is provided with a connection socket that matches the sealing quick connector 306, which facilitates communication with the sealing quick connector 306, and the connection can be maintained by a sealing gasket.

[0060] In some embodiments, the chip removal assembly further includes: a support plate 402, fixedly disposed at one end inside the fixed tube 303, for supporting the chip removal rod 401, and the chip removal rod 401 is fixedly disposed on the support plate 402; and a chip collection cavity 403, opened inside the lower end of the base 2, for collecting larger particles of debris.

[0061] During normal suction, saliva enters the sealed quick-connect joint 306 through the fixed tube 303 and is collected in the collection cylinder on the negative pressure suction assembly 1 through the connected hose. When the sliding tube 301 moves to the moving position due to blockage, the chip removal rod 401 is inserted into the suction port 302. As the sliding tube 301 continues to move, the chip removal rod 401 extends further out of the suction port 302. When the chip removal rod 401 pushes the blocked debris out of the suction port 302, the increased distance between the debris and the suction port 302 reduces the adhesion force of the debris, and the debris falls into the chip collection chamber 403 by its own weight for centralized collection.

[0062] In this embodiment, by cleaning the debris, the sliding tube 301 is released from its closed state, the internal negative pressure is reduced, and the sliding tube 301 is reset by the rebound action of the return spring 305, thereby achieving self-cleaning and collection of larger particles and ensuring the continuity of saliva suction.

[0063] It should be noted that there are several sets of saliva suction ports 302 and several sets of chip removal rods 401, and each set of chip removal rods 401 corresponds to the saliva suction port 302.

[0064] Furthermore, the diameter of the chip removal rod 401 is smaller than the diameter of the suction port 302, which facilitates the reduction of negative pressure inside the sliding tube 301 after cleaning up the debris, thereby allowing it to reset.

[0065] The support plate 402 has a cross-shaped structure to ensure the flow of saliva.

[0066] Working principle or structural principle: When in use, the disposable base 2 is placed in the patient's mouth, the occlusal pad supports the mouth opening, the tongue guard 5 isolates the tongue and forms a moisture barrier in the surgical area, thus achieving mouth opening support, cheek retraction, tongue isolation and surgical area closure. The negative pressure suction component 1 is activated, and the negative pressure power is transmitted to the fixed tube 303 through the hose and the sealed quick connector 306, and then enters the sliding tube 301. Saliva, rinsing water and fine debris in the oral cavity are sucked into the tube through the saliva suction port 302 and finally flow into the saliva collection tube of the negative pressure suction component 1.

[0067] When larger particles such as tartar and tooth debris block the suction port 302, the front end of the sliding tube 301 is sealed, and the internal negative pressure increases. Under the continuous negative pressure, the sliding tube 301 is driven to slide backward along the outside of the fixed tube 303, while the return spring 305 is compressed. During the backward movement of the sliding tube 301, the chip removal rod 401 fixed inside is inserted from the outside of the suction port 302 to push the blockage debris outward. After the debris loses the negative pressure adsorption force, it falls into the chip collection cavity 403 inside the base 2 by its own weight to complete the collection.

[0068] After the debris is removed, the negative pressure inside the sliding tube 301 returns to balance, the reset spring 305 rebounds, and the sliding tube 301 is moved forward to reset, the saliva suction channel is reopened, and the instrument returns to normal saliva suction state. The whole process is automatically triggered, automatically removes debris, and automatically resets through negative pressure difference, without manual intervention. It continuously maintains unobstructed saliva suction and moisture isolation, realizing continuous suction of saliva, waste fluid, and fine debris during the operation, as well as automatic cleaning and centralized collection of large particles, ensuring that the treatment process is continuous, efficient, and safe.
