Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a medical oral saliva processing device. Background Art

[0002] The tongue is a highly active and multifunctional organ in the human oral cavity. Among them, grooved tongue is a typical oral disease. The main symptom is the presence of vertical and horizontal grooves on the tongue surface. According to clinical diagnosis, some patients have grooves or cracks on the back of the tongue that are more than 2mm deep and more than 15mm long, and they feel pain when eating irritating foods. Therefore, it is usually treated with surgery. During the operation, a V-shaped incision will be made along the groove, and then the epithelium in the groove will be removed and sutured to eliminate the patient's grooves and fissures. After the operation, patients usually apply drugs to prevent bacteria, but saliva will be continuously secreted in the mouth. Due to the presence of a large number of bacteria in the saliva, when the patient swallows saliva, the saliva will flow to the post-operative tongue surface and enter the throat, which will not only wash away the medicine, but the saliva will also adhere to the wound and further aggravate the infection of the wound. Therefore, it is usually necessary to treat the saliva that is often secreted in the patient's mouth.

[0003] Long-term clinical diagnosis has found that the use of medical absorption sponges or absorption pads has a strong adsorption capacity and can effectively process the patient's saliva. The absorption pad usually only needs to be placed on the patient's lower jaw near the root of the tongue, and it can absorb the patient's saliva secreted at any time. However, with clinical use, it has been found that the use of the absorption pad needs to be replaced frequently, which undoubtedly greatly increases the workload of medical staff. In addition, foreign matter enters the oral cavity, which can easily cause the patient's saliva secretion to accelerate, so the use effect is not ideal. Therefore, considering portability, the current clinical application of saliva suction treatment devices mainly relies on external suction components to achieve the suction of saliva accumulated in the oral cavity. The treatment device usually includes a hand-held airbag, a accommodating chamber and a suction hose, wherein the accommodating chamber has two openings, one of which is connected to the hand-held airbag, and the other opening is connected to the suction hose. When in use, the patient places the suction hose in the lower jaw of the oral cavity and squeezes the hand-held airbag to allow the saliva in the mouth to be sucked.

[0004] However, the above-mentioned existing oral saliva processing devices mainly use adsorption to process the saliva accumulated in the lower jaw of the oral cavity when the patient's saliva accumulates too much. Although it avoids the patient's frequent swallowing of saliva and reduces the infection of the tongue wound, foreign matter entering the oral cavity and medicine applied on the tongue will continuously stimulate the patient's oral cavity and continuously secrete more saliva, which forces the patient to frequently suck the saliva, which is troublesome and blindly sucking the saliva will easily make the patient's throat dry, and often experience dry throat nausea and even dehydration, thereby causing physical discomfort to the patient. Summary of the invention

[0005] The present invention provides a medical oral saliva processing device, which can process the saliva accumulated by the patient in a portable manner and improve the comfort of the patient in use.

The one-way valve includes two semicircular fan plates that can rotate close to each other and a reset member connected to the two fan plates. As the piston body slides toward the side close to the first port, the fan plates in the through pipe are rotated and spliced ​​into a circular plate shape to block the through pipe. The two fan plates in the suction pipe are in an open state to suck the patient's saliva. When the piston body slides in the opposite direction, the saliva poured into the through pipe is squeezed to the second port.

[0009] Preferably, the height of the through tube gradually decreases from the turning section toward the side adjacent to the suction tube, and the height of the through tube gradually increases in the direction of extension from the side adjacent to the suction tube to the second port, so that after the patient wears it, the second port is just on the upper surface of the tongue root and close to the throat entrance.

[0010] Preferably, the reset member includes a semi-annular sleeve, a semi-annular ring tube movably connected in the sleeve, and a reset spring, the end of the ring tube is fixedly connected to one of the fan plates, and the sleeve is fixedly connected to the other fan plate. The one-way valve also includes a shaft body, which is fixedly connected to the center of the fourth port of the through pipe or the suction pipe. The shaft body has the same inner diameter length as the through pipe or the suction pipe, and the straight side walls of the two semicircular fan plates are hinged to the side walls of the shaft body.

[0011] Preferably, the driving part comprises: an upper jaw hoop, two cylinders, and two piston rods. The upper jaw hoop has the same shape as the two through tubes after being spliced ​​together, and its size is smaller than that of the two through tubes after being spliced ​​together. The upper jaw hoop is symmetrically arranged above the two through tubes for fitting with the patient's upper jaw. The pipe section of the upper jaw hoop close to the first port of the through tube is also a straight section. The two lower ends of the upper jaw hoop away from the straight section are respectively hinged to the side walls of the two through tubes close to the corresponding suction tubes. The lower ends of the two cylinders are respectively sealed and connected with the first ports of the corresponding through tubes through a rotating sleeve, the rotating sleeve is sleeved at the first port of the through tube and the two are rotatably connected, the two piston rods are respectively sealed and slidably connected in the two cylinders, the upper end of the piston rod is fixedly connected with a sleeve, and the sleeve is rotatably sleeved on the straight section of the upper jaw hoop, the gas in the cavity between the piston rod and the piston body is compressed gas, and the lower end of the piston of the piston rod is connected with an extrusion spring.

[0012] Preferably, the second pipe section and the pipe section of the through pipe from the side adjacent to the suction pipe to the second port are made of food-grade rubber material.

[0013] Preferably, the second end of the through pipe is connected to a liquid balancing pan, and the liquid balancing pan is provided with a plurality of openings.

[0014] Preferably, the cavity between the piston rod and the piston body is filled with a liquid medium, and the piston of the piston rod and the piston body are connected by a pulling rope.

[0015] Preferably, the height at which the first tube portion obliquely extends upward is higher than the bottom of the patient's tongue base.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: compared with the existing oral saliva processing device, the present device can directly adsorb the accumulated saliva in the patient's oral cavity, and can directly deliver the adsorbed saliva to the patient's throat entrance, thereby avoiding the patient's frequent and troublesome saliva suction outwards. While ensuring that the medicine on the patient's upper tongue surface is not washed away, the present device delivers the saliva secreted in the patient's oral cavity to the throat entrance, thereby avoiding the patient's oral cavity and throat cavity from being easily dry, and also preventing the phenomenon of dry throat, nausea and even dehydration. Therefore, the patient's use experience is greatly improved. Specifically, the present device can be placed in the patient's lower jaw in the oral cavity by being arranged on two through tubes. On both sides, each through tube is connected with a suction tube, so that the double channels can be used to respectively realize the effect of efficiently suctioning the saliva that is easy to gather in the patient's lower jaw. By limiting the two through tubes to be U-shaped and symmetrical, it can match the patient's lower jaw shape, specifically the U-shape on the inner side of the lower teeth, so that the patient can wear it more comfortably and place it more stably. By limiting the second port of the through tube to be able to extend into the entrance of the patient's laryngeal cavity, it can be achieved that after the saliva is transported to the second port, the saliva can directly flow into the entrance of the patient's laryngeal cavity, thereby facilitating the patient to swallow the saliva and achieving the effect of moisturizing the throat with native saliva. Specifically, since the lower jaw of the patient's mouth is usually higher than the root of the tongue near the teeth, if Figure 1 As shown, the second port extends upward, and its height is higher than the upper tongue surface of the tongue root, and extends downward through the third port of the suction tube. When the patient wears it, the third port of the suction tube extends just toward the lowest point of the patient's lower jaw. When saliva gathers in the patient's lower jaw, the gathered saliva is sucked out by the guide component, and the sucked saliva can enter the through tube through the suction tube. The set driving part can drive the piston body to slide left and right along the horizontal section of the through tube. When the piston body slides toward the first port of the through tube, that is, to the left, it can achieve negative pressure suction force on the suction tube. When the piston body slides along the horizontal section of the through tube toward the second port of the through tube, that is, to the right, it can achieve the effect of squeezing saliva.

[0017] By providing a one-way valve at the fourth port of the suction tube close to one side of the through tube and at a position in the through tube between the second port and the fourth port of the suction tube, its purpose is that when the piston body slides toward the first port of the through tube, that is, to the left, the fourth port of the suction tube is in an open state, and the position in the through tube between the second port and the fourth port of the suction tube is in a sealed state. At this time, as the piston body continues to slide, a negative pressure suction force is provided to the suction tube so that saliva is sucked and enters the through tube. At the same time, when the piston body slides toward the second port of the through tube, that is, to the right, the fourth port can be blocked, and the second port of the through tube can be ensured to be in an open state, so that saliva can smoothly pass through the one-way valve in the through tube and enter the patient's throat. Therefore, this structure is realized by adopting two fan plates with elastic reset ability. Specifically, when a force is given to the two fan plates in the through tube toward the second port, the two fan plates can rotate toward the second port. When the force disappears, the two fan plates can return to a circular plate-shaped structure under the effect of the reset member. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] refer to Figure 1 , Figure 2 and Figure 3The present invention provides a medical oral saliva processing device, comprising two through tubes 1 for being placed on both sides of the lower jaw in the oral cavity of a patient, two suction tubes 2 and two guide components 3. The two through tubes 1 are symmetrical in a U shape, the first ports 11 of the two through tubes 1 are straight and opposite, and the second ports 12 are used to extend into the entrance of the laryngeal cavity of the patient, the two suction tubes 2 are respectively connected to the side walls of the two through tubes 1 near the respective second ports 12, the suction tubes 2 extend downward away from the third port 21 of the through tubes 1, and are used to extend into the lower jaw of the patient where saliva is collected, the guide component 3 is used to suck saliva into the through tube 1 through the suction tube 2 and send it to the entrance of the laryngeal cavity of the patient through the through tube 1, the guide component 3 comprises: a piston body 31 and two one-way valves, the piston body 31 is placed in the through tube 1, and the section between the turning part of the through tube 1 and the suction tube 2 is a straight section, The piston body 31 is movably connected to the straight section of the through pipe 1. The piston body 31 slides back and forth along the straight section of the through pipe 1 under the drive of the driving part 32. The two one-way valves are respectively connected to the fourth port 22 of the suction pipe 2 close to the through pipe 1 and a position in the through pipe 1 between the second port 12 and the fourth port 22 of the suction pipe 2. The one-way valve includes two semicircular fan plates 33 that can rotate close to each other and a reset member 34 connected to the two fan plates 33. As the piston body 31 slides toward the side close to the first port 11, the fan plates 33 in the through pipe 1 are rotated and spliced ​​into a circular plate shape to block the through pipe 1. The two fan plates 33 located in the suction pipe 2 are in an open state to suck the patient's saliva. When the piston body 31 slides in the opposite direction, the saliva poured into the through pipe 1 is squeezed to the second port 12.

[0031] In the above embodiments, compared with the existing oral saliva processing device, the present device can directly adsorb the accumulated saliva in the patient's oral cavity, and can directly deliver the adsorbed saliva to the entrance of the patient's laryngeal cavity, thereby avoiding the patient's frequent and troublesome suction of saliva outwards. While ensuring that the medicine on the patient's upper tongue surface is not washed away, the present device delivers the saliva secreted in the patient's oral cavity to the entrance of the laryngeal cavity, thereby avoiding the patient's oral cavity and laryngeal cavity from being easily dry, and will not cause dry throat, nausea or even dehydration. Therefore, the patient's user experience is greatly improved. Specifically, the present device is provided with two through tubes 1, which can be placed on both sides of the patient's lower jaw in the oral cavity, and each through tube 1 is The suction tube 2 is connected, and the dual channels can be used to respectively realize the effect of efficiently suctioning the saliva that is easy to gather in the patient's lower jaw. By limiting the two through tubes 1 to be symmetrical in a U-shape, it can match the shape of the patient's lower jaw, specifically the U-shape on the inner side of the lower teeth, so that the patient can wear it more comfortably and place it more stably. By limiting the second port 12 of the through tube 1 to be able to extend into the entrance of the patient's laryngeal cavity, it can be achieved that after the saliva is transported to the second port 12, the saliva can directly flow into the entrance of the patient's laryngeal cavity, thereby facilitating the patient to swallow the saliva and achieving the effect of moisturizing the throat with native saliva. Specifically, since the lower jaw of the patient's mouth is usually higher than the root of the tongue near the teeth, Figure 1As shown, the second port 12 extends upward, and its height is higher than the upper tongue surface of the tongue root, and extends downward through the third port 21 of the suction tube 2. When the patient wears it, the third port 21 of the suction tube 2 extends just toward the lowest point of the patient's lower jaw. When saliva gathers on the patient's lower jaw, the gathered saliva is sucked by the guide component 3, and the sucked saliva can enter the through tube 1 through the suction tube 2. The set driving part 32 can drive the piston body 31 to slide left and right along the horizontal section of the through tube 1. When the piston body 31 slides toward the first port 11 of the through tube 1, that is, slides to the left, it can achieve negative pressure suction force on the suction tube 2. When the piston body 31 slides along the horizontal section of the through tube 1 toward the second port 12 of the through tube 1, that is, slides to the right, it can achieve the effect of squeezing saliva.

[0032] One-way valves are provided at the fourth port 22 of the suction tube 2 close to the through tube 1 and at a position between the second port 12 and the fourth port 22 of the suction tube 2 in the through tube 1. When the piston body 31 slides toward the first port 11 of the through tube 1, that is, to the left, the fourth port 22 of the suction tube 2 is in an open state, and the position between the second port 12 and the fourth port 22 of the suction tube 2 in the through tube 1 is in a sealed state. At this time, as the piston body 31 continues to slide, negative pressure suction force is provided to the suction tube 2, so that saliva is sucked and enters the through tube 1. At the same time, when When the piston body 31 slides toward the second port 12 of the through tube 1, that is, to the right, the fourth port 22 can be blocked and the second port 12 of the through tube 1 can be ensured to be in an open state, so that saliva can smoothly pass through the one-way valve in the through tube 1 and enter the patient's throat. Therefore, the present structure is implemented by using two fan plates 33 with elastic reset capability. Specifically, when a force is applied to the two fan plates 33 in the through tube 1 toward the second port 12, the two fan plates 33 can rotate toward the second port 12. When the force disappears, the two fan plates 33 can return to a circular plate-shaped structure under the effect of the reset member 34.

[0033] Further, refer to Figure 2 The distance between the two through pipes 1 at the turning section is greater than the distance between the second ends 12 of the two through pipes 1 .

[0034] In the above embodiments, by limiting the spacing dimension between the two through tubes 1 at the turning sections to be larger than the spacing dimension between the second ports 12 of the two through tubes 1, the purpose is to match the space dimension of the patient's lower jaw close to the oral cavity to be larger than the space dimension close to the root of the tongue, thereby ensuring the patient's comfort and avoiding a strong foreign body sensation after the patient wears the product.

[0035] Further, refer to Figure 1 , Figure 2 and Figure 4The suction pipe 2 includes a first pipe section 23 connected to the through pipe 1 and a second pipe section 24 connected to the first pipe section 23. The third port 21 is located on the second pipe section 24. The fourth port 22 is located at the first pipe section 23. The portion of the first pipe section 23 away from the fourth port 22 extends upward at an angle. The second pipe section 24 connected to the first pipe section 23 is in the shape of a curved pipe extending downward.

[0036] In the above embodiment, by limiting the first tube segment 23 to extend upwardly at an angle away from the fourth port 22, it is possible to achieve that after the second tube segment 24 draws saliva to a position close to the first tube segment 23, the saliva can automatically flow to the fourth port 22 by gravity, thereby facilitating the collection of saliva.

[0037] Further, refer to Figure 3 The height of the through tube 1 decreases gradually from the turning section toward the side adjacent to the suction tube 2, and the height of the through tube 1 increases gradually in the extending direction from the side adjacent to the suction tube 2 to the second port 12, so that after the patient wears it, the second port 12 is just on the upper surface of the tongue root and close to the throat entrance.

[0038] In the above embodiments, by limiting the height of the through tube 1 to gradually decrease from the turning section toward the side adjacent to the suction tube 2, it can be achieved that when saliva is sucked into the through tube 1, it will preferentially gather and flow toward the side close to its corresponding one-way valve.

[0039] Further, refer to Figure 6 and Figure 7 The reset member 34 includes a semi-annular sleeve 341, a semi-annular ring tube 342 movably connected in the sleeve 341, and a reset spring 343. The end of the ring tube 342 is fixedly connected to one of the fan plates 33, and the sleeve 341 is fixedly connected to the other fan plate 33. The one-way valve also includes a shaft body 35, which is fixedly connected to the center of the fourth port 22 of the through pipe 1 or the suction pipe 2. The shaft body 35 has the same inner diameter as the through pipe 1 or the suction pipe 2. The straight side walls of the two semicircular fan plates 33 are hinged to the side walls of the shaft body 35.

[0040] In the above embodiments, the annular tube 342 can rotate and slide inside the sleeve 341, and the centers of the two circles are concentrically arranged. When the two fan plates 33 rotate toward each other on the shaft 35, the sleeve 341 and the annular tube 342 will rotate in opposite directions. At this time, the internal return spring 343 is in a compressed state. Specifically, when the two fan plates 33 are combined into a circular plate shape, the relative position of the annular tube 342 and the sleeve 341 is fixed, and the two fan plates 33 will not continue to rotate toward the side away from the sleeve 341. Furthermore, the outer wall of the fan plate 33 is provided with a sealing rubber ring, which can achieve a sealing effect.

[0041] Further, refer to Figure 1 Figure 2 and Figure 3The driving part 32 includes: an upper jaw hoop 321, two cylinders 322, and two piston rods 323. The upper jaw hoop 321 has the same shape as the two through tubes 1 after being spliced ​​together. The size of the upper jaw hoop 321 is smaller than the size of the two through tubes 1 after being spliced ​​together. The upper jaw hoop 321 is symmetrically arranged above the two through tubes 1 to fit the upper jaw of the patient. The pipe section of the upper jaw hoop 321 close to the first port 11 of the through tube 1 is also a straight section. The two lower ends of the upper jaw hoop 321 away from the straight section are respectively hinged to the side walls of the two through tubes 1 close to the corresponding suction tube 2. The two cylinders 322 The lower ends are sealed and connected with the first ports 11 of the corresponding through pipes 1 through the rotating sleeves 3211, the cylinder 322 is fixedly connected with the rotating sleeve 3211, the rotating sleeve 3211 is rotatably sleeved at the first port 11 of the through pipe 1, the two piston rods 323 are sealed and slidably connected in the two cylinders 322, the upper end of the piston rod 323 is fixedly connected with the sleeve 3212, the sleeve 3212 is rotatably sleeved on the straight section of the upper jaw hoop 321, the gas in the cavity between the piston rod 323 and the piston body 31 is compressed gas, and the lower end of the piston of the piston rod 323 is connected with an extrusion spring 324.

[0042] In the above embodiments, the upper jaw hoop 321 is provided, so that the patient can suction saliva at any time and in a portable manner. Specifically, the squeezing spring 324 is in an extended state in the initial state, and the patient can ensure the space between the upper jaw and the lower jaw without opening his mouth, thereby laying a foundation for the tongue not to contact the saliva. At the same time, when the patient needs to suction saliva, he only needs to control his upper jaw to squeeze downward. At this time, the upper jaw hoop 321 will squeeze the piston rod 323 downward. The piston rod 323 can slide along the cylinder 322 with the support of the rotating sleeve 3211 and the sleeve body 3212, thereby achieving the squeezing effect. Of course, when the upper jaw is no longer squeezed, the squeezing spring 324 will give a reset force, which can realize the upward movement of the piston rod 323, thereby ultimately controlling the reciprocating displacement of the piston body 31, and ultimately achieving the effect of the piston body 31 sucking and squeezing the saliva.

[0043] Further, refer to Figure 1 The second pipe section 24 and the pipe section of the through pipe 1 from the side adjacent to the suction pipe 2 to the second port 12 are made of food grade rubber.

[0044] Further, refer to Figure 2 The second port 12 of the through pipe 1 is connected to a liquid balancing pan 4 , and the liquid balancing pan 4 is provided with a plurality of openings 41 .

[0045] In the above embodiments, by providing the liquid equalizing plate 4, it is possible to further achieve that the saliva flowing out of the second port 12 can be evenly distributed to the throat of the patient, thereby achieving a global throat moisturizing effect.

[0046] Further, refer to Figure 3The cavity between the piston rod 323 and the piston body 31 is filled with liquid medium 5, and the piston of the piston rod 323 is connected to the piston body 31 through a pulling rope 6.

[0047] In the above embodiment, when the piston rod 323 moves downward, the liquid medium 5 can be used to squeeze the piston body 31 so that it slides along the through tube 1. The pulling rope 6 provided therein can have the beneficial effect of pulling and controlling the piston body 31 when the piston rod 323 moves upward.

[0048] Further, refer to Figure 3 and Figure 4 The first tube portion extends obliquely upward to a height that is higher than the bottom of the patient's tongue root.

[0049] In the above embodiments, in order to prevent the medicine on the upper tongue from being dispersed and causing bacterial growth in the wound, most patients will press the tip of the tongue against the upper palate to lift the tongue. Over time, they will feel very tired. When the tongue is relaxed and the patient's throat is in the process of swallowing saliva, saliva is easy to flow into the upper tongue. Therefore, the device can provide a certain lifting force for the patient's tongue by limiting the height of the first tube portion extending upward at an angle higher than the bottom height of the patient's tongue root. When the patient uses the device, the tongue can be assisted in lifting up without feeling tired, thereby improving the patient's comfort. In order to further improve the comfort of the patient's tongue, a food-grade rubber or latex tongue support 7 is provided on the first tube segment 23 adjacent to the second tube segment 24. Specifically, the tongue support 7 has a plurality of through holes opened vertically.

[0050] The material of the through pipe 1, the upper jaw hoop 321, the piston rod 323 and the cylinder body 322 are all 304 steel.

[0051] By limiting the material of the through tube 1, the upper jaw hoop 321, the piston rod 323 and the cylinder 322 to 304 steel, it is possible to ensure the safety of patients while reducing the weight.

[0052] This embodiment takes into account that some patients' saliva may be mixed with food residues, which may easily clog the suction tube 2 over time. Therefore, an isolation net 8 for blocking food residues in the patient's mouth is connected to the third port 21 extending downward from the suction tube 2. The isolation net 8 is made of 304 steel.

[0053] The above disclosures are only several specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
