Description

Technical Field

[0001] This utility model relates to the field of dental treatment instruments, and in particular to an intraoral anti-aspiration device for oral treatment. Background Technology

[0002] During oral surgery, especially root canal treatment, there is a risk that the instruments used by the dentist (such as root canal reamers, files, implants, etc.) may fall out of the patient's mouth. If they fall out, they may be inhaled into the trachea or swallowed into the digestive tract, causing serious consequences.

[0003] To prevent this from happening, there are several traditional methods:

[0004] Using a rubber dam is the most professional method. However, it has several drawbacks: First, doctors report that installing a rubber dam is very time-consuming, with doctors spending at least 20 minutes on preparation and installation for each surgery. Second, while the rubber dam itself is not expensive, the instruments used for it are, and some small clinics may be unwilling to purchase them due to cost considerations. Third, the rubber dam needs to be inserted into the patient's teeth, which can be uncomfortable for some patients, and some may even require anesthesia for successful installation. Therefore, using a rubber dam solely to prevent accidental inhalation of foreign objects is not entirely worthwhile.

[0005] Experienced dentists will thread a suture through the root canal reamer or file and hang it in their hand to prevent it from accidentally falling into the patient's mouth. The disadvantage is that a single surgery uses many different types of small dental instruments, each of which needs to be threaded, which is very time-consuming for the dentist. In addition, the shape of some instruments is not suitable for threading (such as pulp apex needles, pulp washing needles, implants, etc.). Utility Model Content

[0006] To overcome the above-mentioned defects, this utility model provides an intraoral anti-aspiration device for oral treatment. This intraoral anti-aspiration device for oral treatment is easy to use, will not cause discomfort to the patient, and can effectively prevent the treatment instrument from falling into the patient's mouth, thus fully protecting the patient's oral cavity.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: an intraoral anti-aspiration device for oral treatment, including a rigid support and an elastic sleeve. The rigid support forms a V-shaped structure, and the elastic sleeve, made of elastic material, is tightly fitted on the outside of the rigid support. The rigid support and the elastic sleeve together form a V-shaped shielding structure that matches the shape of the patient's open maxilla and mandible. One end of the V-shaped shielding structure can abut against the alveolar bone around the patient's mandibular tongue, and the other end can abut against the palate of the patient's maxilla.

[0008] As a further improvement of this utility model, the rigid support is an annular rigid support tube formed by connecting the ends. The rigid support tube is bent from the middle of the annulus to form a V-shaped ring. An elastic sleeve is tightly fitted on the outside of the rigid support tube to form a V-shaped shielding structure. It is also provided with a saliva suction tube connector and a saliva suction tube. At least one saliva suction tube connector is fixedly installed on the side wall of the rigid support tube. The connector end of the saliva suction tube connector extends to the outside of the elastic sleeve. One end of the saliva suction tube is sealed and fitted on the connector end of the saliva suction tube connector to achieve communication with the inner channel of the rigid support tube. The other end of the saliva suction tube can be connected to a saliva suction device. The saliva suction device can draw saliva into the rigid support tube through the saliva suction tube. The rigid support tube and the elastic sleeve are provided with a number of saliva inlet holes corresponding to each other. The saliva secreted by the patient during oral treatment can enter the rigid support tube through the saliva inlet holes.

[0009] As a further improvement of this utility model, the rigid support tube includes an upper support section, a lower support section, and a middle support section. The upper support section forms a semi-elliptical arc structure that matches the upper jaw of the human mouth, the lower support section forms a semi-elliptical arc structure that matches the lower jaw of the human mouth, and the middle support section is a straight or arc structure. The saliva suction tube connector is located on the middle support section. Both ends of the upper support section are connected to one end of the two middle support sections, and both ends of the lower support section are connected to the other end of the two middle support sections. The upper support section, the middle support section, and the lower support section together form a flat-bottomed V-shaped structure or an arc-bottomed V-shaped structure.

[0010] As a further improvement of this utility model, the upper support section and half of the middle support section of the rigid support tube are integrally formed into an upper support tube, and the lower support section and the other half of the middle support section are integrally formed into a lower support tube. The saliva suction tube connector is a three-way tube. The first channel of the three-way tube is fixedly connected to the end of the upper support tube and is internally connected. The second channel of the three-way tube is fixedly connected to the end of the lower support tube and is internally connected. The third channel of the three-way tube forms the connector end of the saliva suction tube connector.

[0011] As a further improvement of this utility model, the rigid support tube is composed of at least one straight tube and at least one corrugated tube along its extension direction. By stretching the corrugated tube, the size of the V-shaped structure formed by the rigid support tube and the included angle of the V-shaped structure can be changed.

[0012] As a further improvement of this utility model, a built-in flexible tube is also provided. Two built-in flexible tubes are respectively inserted into the upper support tube and the lower support tube, and the two ends of the built-in flexible tubes extend out of the outer side of the ends of the upper support tube and the lower support tube by a certain length. The two ends of the built-in flexible tubes are respectively sleeved on the outer side of the first channel and the second channel of the three-way tube for sealing and connection. The saliva inlet hole penetrates through the side wall of the built-in flexible tube.

[0013] As a further improvement of this utility model, the distribution density of the saliva inlets corresponding to each other on the rigid support tube and the elastic sleeve is greater near the various salivary glands of the patient's mandible than in other locations.

[0014] As a further improvement of this utility model, the rigid support tube is a plastic straw.

[0015] As a further improvement of this utility model, the elastic sleeve is an oval-shaped bag-like latex sleeve with an open end.

[0016] The beneficial effects of this invention are as follows: This invention uses a rigid support tube to form a V-shaped structure that matches the shape of the patient's open mouth, and an elastic sleeve is fitted over it. In use, the invention is inserted into the patient's mouth, pressing against the patient's maxilla and palate, and the area around the tongue and mandible. The patient's mouth is in contact with the elastic sleeve, causing no discomfort. Simultaneously, the elastic sleeve provides protection for the patient's throat, maxilla, and tongue, preventing accidental aspiration of the small oral treatment device and protecting the patient's tongue. Furthermore, the invention uses a corrugated plastic straw as the rigid support tube, which allows for deformation and size adjustment. This device is easy to place in the patient's mouth and can be used in oral cavities of different sizes, saving the doctor's operating time. It employs a combined inner flexible tube and an outer rigid tube design. The outer rigid tube can be bent, stretched, and shaped, while the inner flexible tube has resilience. This allows for better retention by referencing the patient's dental arch shape and bending the combined tube to match the arch. Utilizing the rigidity and resilience of the combined tube, it functions as an intraoral mouth opener, making it effortless for the patient to open their mouth, and eliminating the doctor's concern about being bitten on the finger. It can also be connected to an external saliva suction device, providing a large suction range without frequently inserting the suction device into the patient's mouth, thus avoiding interference with the doctor's operation. Because the components are low-cost to manufacture and disposable, this device helps prevent cross-infection and reduces costs for clinics. Attached Figure Description

[0046] Example: An intraoral aspiration prevention device for oral cavity treatment 5 includes a rigid support 1 and an elastic sleeve 2. The rigid support 1 forms a V-shaped structure. The elastic sleeve 2, made of elastic material, is tightly fitted on the outside of the rigid support. The rigid support 1 and the elastic sleeve 2 together form a V-shaped shielding structure that matches the shape of the maxilla and mandible of the patient's open oral cavity 5. One end of the V-shaped shielding structure can abut against the alveolar bone 51 around the tongue of the patient's mandible, and the other end can abut against the palate 52 of the patient's maxilla. The device uses a rigid support 1 bent into a V-shape as the shielding connector. The outer side is tightly covered with an elastic sleeve 2, which contacts the patient's oral cavity 5. The elastic sleeve 2 is made of silicone, which is closer to human skin. The elastic sleeve 2 forms a shielding surface. This device is inserted into the patient's oral cavity 5, pressing against the patient's maxillary palate 52 and mandibular tongue area, blocking the patient's throat. It plays a role in preventing the patient from accidentally inhaling the tiny oral cavity treatment instrument that may fall out. It is convenient to use, saves doctors' operation time, and improves the patient's comfort.

[0047] The rigid support 1 is an annular rigid support tube formed by connecting the ends. The rigid support tube is bent from the middle of the annulus to form a V-shaped ring. The elastic sleeve 2 is tightly fitted on the outside of the rigid support tube to form a V-shaped shielding structure. It is also provided with a saliva suction tube connector 3 and a saliva suction tube 4. At least one saliva suction tube connector 3 is fixedly installed on the side wall of the rigid support tube. The connector end 31 of the saliva suction tube connector 3 extends to the outside of the elastic sleeve 2. One end of the saliva suction tube 4 is sealed and fitted on the connector end 31 of the saliva suction tube connector 3 to achieve communication with the inner channel of the rigid support tube. The other end of the saliva suction tube 4 can be connected to a saliva suction device. The saliva suction device can draw saliva into the rigid support tube through the saliva suction tube 4. The rigid support tube and the elastic sleeve 2 are provided with a number of saliva inlet holes 11 corresponding to each other. The saliva secreted by the patient during oral treatment 5 can enter the rigid support tube through the saliva inlet holes 11.

[0048] By bending the rigid support tube into a V-shaped ring as an internal support, and utilizing its internal channels to form a saliva-containing and flow channel, during oral treatment, the saliva and other treatment fluids in the patient's mouth can be promptly suctioned away by the saliva aspirator through the saliva aspirator tube connector 3 and the saliva aspirator tube 4, keeping the patient's oral cavity clean, preventing excessive saliva from affecting the doctor's operation, and also avoiding the patient from choking on excessive saliva that may be aspirated into the trachea during treatment.

[0049] The rigid support tube includes an upper support section, a lower support section, and a middle support section. The upper support section forms a semi-elliptical arc structure that matches the maxilla of the human oral cavity 5, and the lower support section forms a semi-elliptical arc structure that matches the mandible of the human oral cavity 5. The middle support section has a straight or arc-shaped structure. The suction tube connector 3 is located on the middle support section. Both ends of the upper support section are connected to one end of each of the two middle support sections, and both ends of the lower support section are connected to the other ends of each of the two middle support sections. The upper support section, middle support section, and lower support section together form a flat-bottomed V-shaped structure or an arc-bottomed V-shaped structure. This structure allows the rigid support tube to form a flat-bottomed or arc-bottomed V-shaped structure, which better matches the human oral cavity 5 and can fully protect the patient's pharynx.

[0050] The rigid support tube has its upper section and half of the middle support section integrally formed as an upper support tube 12, and its lower section and the other half of the middle support section integrally formed as a lower support tube 13. The saliva suction tube connector 3 is a T-junction. The first channel of the T-junction is fixedly connected to the end of the upper support tube 12 and internally connected. The second channel of the T-junction is fixedly connected to the end of the lower support tube 13 and internally connected. The third channel of the T-junction forms the connector end 31 of the saliva suction tube connector 3. The upper support tube 12 and the lower support tube 13 are connected through two T-junctions. The split structure is easy to manufacture.

[0051] The rigid support tube consists of at least one straight tube 15 and at least one corrugated tube 14 along its extension direction. By stretching the corrugated tube 14, the size and angle of the V-shaped structure formed by the rigid support tube can be changed. The size and shape of the rigid support tube can be adjusted using the expansion and contraction capability of the corrugated tube 14, adapting to the size and shape of different patients' oral cavity 5. Besides using a structure where the corrugated tube 14 and the straight tube 15 cooperate to adjust the length and shape of the rigid support tube, an outer tube can be used to enclose the inner tube, changing the length of the rigid support tube by pulling. The rigid support tube can be made of a material with bending capabilities to achieve shape adjustment.

[0052] It also includes two internal flexible tubes 6, which are respectively inserted into the upper support tube 12 and the lower support tube 13. Both ends of the internal flexible tubes 6 extend a predetermined length beyond the outer sides of the ends of the upper and lower support tubes 12 and 13, respectively. The two ends of the internal flexible tubes 6 are respectively fitted onto the outer sides of the first and second channels of the three-way tube for sealing and connection. The saliva inlet 11 penetrates the sidewall of the internal flexible tubes 6. This combined design of the internal flexible tubes 6 and the external rigid support tubes allows for shaping of the external rigid support tubes and provides resilience to the internal flexible tubes 6. This allows for adaptation to the patient's dental arch shape, and the combined tubes can be bent to match the patient's dental arch shape for better retention.

[0053] The saliva inlets 11 on the rigid support tube and elastic sleeve 2 have a higher distribution density near the salivary glands of the patient's mandible than in other locations. This allows for the immediate suction of saliva secreted in the patient's oral cavity 5.

[0054] The rigid support tube is a plastic straw. The plastic straw itself has 14 corrugated sections, which is easy to manufacture and inexpensive, resulting in extremely low production costs. It can be used for single purposes, which helps prevent cross-infection and also helps clinics reduce costs. In addition, the rigid support tube can also be made of metal tubes or other plastic tubes, as long as they have a certain supporting strength and preferably a certain degree of bending and deformation ability.

[0055] The elastic sleeve 2 is an oval-shaped, bag-like latex sleeve with an open end.

[0056] The method for manufacturing the oral cavity treatment intraoral aspiration prevention device includes the following steps:

[0057] Step 1: Measure the length of the inner arch of the alveolar ridge of the maxillary palatal region 52 and the mandibular lingual region of the patient's oral cavity 5, and cut two silicone inner tubes 6 according to this length.

[0058] Step 2: Cut two plastic straws with a corrugated tube 14 in the middle, about 2 / 3 to 3 / 4 of the length of the inner tube 6, so that they are symmetrical at both ends with the corrugated tube 14 in the middle as the center.

[0059] Step 3: Insert the inner tube 6 into the cut plastic straw, with both ends of the inner tube 6 extending symmetrically outwards from both ends of the plastic straw. Since the inner tube 6 is relatively long, ensure that both sides of the inner tube 6 are symmetrically exposed, forming a combined tube that is soft inside and hard outside.

[0060] Step 4: Insert the two coaxial ends of the T-shaped three-way tube into the built-in flexible tubes 6 that extend to the outside of the two plastic straws to achieve a sealed connection, thereby forming a closed loop tube;

[0061] Step 5: Place the oval-shaped latex sleeve with one open end over the outside of the ring tube formed in step 3, narrow and flatten the ring tube, rotate the tee tube to make it on the same plane as the ring tube, and fully insert the ring tube into the latex sleeve from the open end of the latex sleeve.

[0062] Step 6: Rotate the two T-tubes inside the latex sleeve so that their connector ends 31 are upright. At this time, the connector ends 31 of the T-tubes protrude and press against the latex sleeve. Use a probe to pierce the protruding latex sleeve and extend the connector ends 31 of the T-tubes out of the latex sleeve.

[0063] Step 7: Attach one end of the saliva suction tube 4 to the connector end 31 of the exposed latex sleeve of the three-way tube, and install a reducing two-way connector on the other end of the saliva suction tube 4 for connecting to a saliva suction device during surgery.

[0064] Step 8: Use a punch to punch holes in the plastic straw and inner tube 6 inside the latex sleeve to form saliva inlet holes 11, so that water can enter the inner wall of the tube when sucking saliva and eventually be sucked out by the saliva suction tube. Make as many holes as possible without affecting the strength, especially near the salivary glands in the lower jaw, so that it is easier to suck saliva after it is placed in the mouth 5.

[0065] When using the device, bend it appropriately according to the direction of the upper and lower jaws, and place it into the patient's oral cavity 5, ensuring it is stably positioned within the dental arch on the inner side of the alveolar bone 51 of the palate and lower tongue. Note that after the latex sleeve is fully inserted, the open side is the lower jaw, and the closed side is the upper jaw. Then, slightly bend the connecting tube again to make its shape more closely resemble the dental arch shape on the inner side of the alveolar bone 51 of the patient's oral cavity 5, completely obstructing the patient's throat without affecting breathing or the field of vision of the teeth on the affected side. Connect the saliva suction tube to the suction tube of the treatment machine using a reducing two-way connector. The aspiration prevention device is now installed. After the doctor finishes treatment, remove the aspiration prevention device and dispose of it properly.
