Description

Technical Field

[0001] This utility model relates to the technical field of negative pressure suction devices, and in particular to a medical oral continuous negative pressure suction device. Background Technology

[0002] In existing technologies, one end of the suction tube is directly connected to the collection tube on the collection bottle, while the other end is simply inserted into the oral cavity for suction. This design has significant shortcomings. First, when the suction tube is directly inserted into the oral cavity, the lack of a specialized design to adapt to the oral structure causes significant discomfort to the patient. Not only can the hard material irritate or damage the oral mucosa, but the absence of a proper cushioning mechanism also makes prolonged use more painful. Furthermore, the connection method in traditional designs is not very secure, and in actual use, the suction tube is easily dislodged due to slight patient movements or improper operation. This not only seriously affects the suction effect and treatment progress, but the unstable connection may also lead to fluid leakage, increasing the risk of cross-infection. Therefore, we propose a medical oral continuous negative pressure suction device. Utility Model Content

[0003] The main objective of this invention is to provide a medical oral continuous negative pressure suction device that can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A medical oral continuous negative pressure suction device includes a collection bottle. A connecting protrusion is integrally formed on the upper end of the collection bottle. A bottle cap is detachably mounted on the upper end of the collection bottle via the connecting protrusion. Two symmetrically arranged handles are fixedly connected to the upper end of the bottle cap. A connecting tube communicating with the interior of the collection bottle is inserted through the middle of the upper end of the bottle cap. A vacuum negative pressure suction pump is fixedly connected to the upper end of the connecting tube. A pressure gauge is installed on the upper end of the vacuum negative pressure suction pump. A collection tube communicating with the interior of the collection bottle is inserted through one side of the outer surface of the collection bottle. A suction body is provided at one end of the collection tube, and fasteners are provided on the collection tube.

[0006] Preferably, the suction body includes a suction tube, one end of which is inserted into the collection tube and fixed by a fastener, and the other end of the suction tube is fixedly connected to a connector, and the end of the connector away from the suction tube is detachably fitted with a mouthpiece.

[0007] By adopting the above technical solution, quick assembly and disassembly are achieved through the threaded connection between the mouthpiece and the connector on the suction tube, which not only facilitates cleaning and replacement but also effectively prevents cross-infection.

[0008] Preferably, the fastener includes a fixing plate, which is fixedly sleeved on the liquid collection pipe. One end of the liquid collection pipe is fixedly connected to two support plates that are symmetrically distributed vertically. The middle of each of the two support plates is threaded with an adjusting screw, and the opposite ends of each of the two adjusting screws are movably connected with a clamping block.

[0009] By adopting the above technical solution, the two clamping blocks are driven to cooperate and clamp and fix the suction tube by rotating the adjusting screw, thereby improving the firmness of the connection between the suction tube and the collection tube and avoiding the problem of loose connection of the suction tube during use.

[0010] Preferably, the clamping block has an arc-shaped structure, and the two clamping blocks are arranged symmetrically from top to bottom, with rubber pads fixedly connected to the opposite ends of the two clamping blocks.

[0011] By adopting the above technical solution, the rubber pads on the surface of the clamping block not only increase friction and make the clamping more stable, but also protect the suction tube from damage and extend its service life.

[0012] Preferably, the mouthpiece includes an installation tube, which is threadedly connected to a connector. One end of the installation tube is fixedly connected to an external protective block, and the end of the external protective block away from the installation tube is fixedly connected to an internal soft suction block.

[0013] By adopting the above technical solutions, both the external protective block and the intraoral soft suction block are made of medical-grade silicone, ensuring that they do not irritate or damage the oral mucosa during use, and can adapt to the oral cavity shape of different patients to improve comfort. At the same time, the design of the external protective block is to prevent patients from accidentally swallowing the oral component during use, and also provides an external support point to increase the stability and comfort of use.

[0014] Preferably, the interior of the intraoral soft suction block is hollow, and a number of suction holes are dispersed on the outer surface of the intraoral soft suction block.

[0015] By adopting the above technical solution, the dispersed design of the suction holes can not only evenly distribute negative pressure, but also reduce local pressure on oral tissues and avoid damage.

[0016] Preferably, the bottom of the liquid collecting bottle is integrally formed with a base, and the bottom area of ​​the base is larger than the bottom area of ​​the liquid collecting bottle.

[0017] By adopting the above technical solution, the base significantly improves the stability of the entire device by increasing the contact area with the placement surface, thus avoiding liquid leakage or equipment damage caused by tipping.

[0018] Preferably, the connecting pipe is equipped with an anti-overflow valve.

[0019] By adopting the above technical solution, the anti-overflow valve ensures that liquid backflow will not occur even when the negative pressure is too high or the collection bottle is full, thus increasing the safety of use.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. Through innovative design of the suction unit, the mouthpiece is equipped with an external protective block and an internal soft suction block. Both the external protective block and the internal soft suction block are made of medical-grade silicone, ensuring no irritation or damage to the oral mucosa during use and improving comfort. The external protective block prevents patients from accidentally swallowing the mouthpiece during use and provides an external support point to increase stability and comfort. The internal soft suction block has multiple suction holes on its surface, ensuring gentle handling of the patient's oral mucosa during operation and reducing discomfort and the risk of injury. Furthermore, the mouthpiece is connected to the suction tube via a threaded connector, making assembly and disassembly simple and quick, facilitating cleaning and replacement, and effectively preventing cross-infection. This is especially suitable for situations requiring frequent equipment changes or cleaning.

[0022] 2. By setting fasteners on the collection pipe, the distance between the two clamping blocks can be precisely controlled by rotating the adjusting screw, thereby achieving a stable clamping of the suction pipe. This improves the firmness and stability of the connection between the suction pipe and the collection pipe, avoiding operational failures or interruptions due to loose connections. At the same time, the rubber pads on the surface of the clamping blocks increase friction and provide a protective layer, preventing the suction pipe from slipping and reducing its wear, extending the service life of the equipment, and improving the safety and reliability of the overall device.

[0028] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0029] Please see Figure 1-4 This utility model provides a technical solution:

[0030] A medical oral continuous negative pressure suction device includes a collection bottle 1. The upper end of the collection bottle 1 is integrally formed with a connecting protrusion 2. A bottle cap 3 is detachably installed on the upper end of the collection bottle 1 through the connecting protrusion 2. Two symmetrically arranged handles 11 are fixedly connected to the upper end of the bottle cap 3. A connecting tube 4 communicating with the inside of the collection bottle 1 is inserted through the middle of the upper end of the bottle cap 3. A vacuum negative pressure suction pump 5 is fixedly connected to the upper end of the connecting tube 4. A pressure gauge 6 is provided on the upper end of the vacuum negative pressure suction pump 5. A collection tube 7 communicating with the inside of the collection bottle 1 is inserted through one side of the outer surface of the collection bottle 1. A suction body 9 is provided at one end of the collection tube 7. Fasteners 8 are provided on the collection tube 7.

[0031] In this embodiment, the suction body 9 includes a suction tube 91. One end of the suction tube 91 is inserted into the collection tube 7 and fixed by a fastener 8. The other end of the suction tube 91 is fixedly connected to a connector 92. The end of the connector 92 away from the suction tube 91 is detachably fitted with an oral component 93. The oral component 93 includes an installation tube 94. The installation tube 94 is threadedly connected to the connector 92. One end of the installation tube 94 is fixedly connected to an external protective block 95. The end of the external protective block 95 away from the installation tube 94 is fixedly connected to an internal soft suction block 96. The internal soft suction block 96 has a hollow structure, and a plurality of suction holes 961 are dispersed on the outer surface of the internal soft suction block 96.

[0032] The above solution utilizes an innovative design for the suction unit 9, employing an oral component 93. The oral component 93 includes an external protective block 95 and an intraoral soft suction block 96, both made of medical-grade silicone. This ensures no irritation or damage to the oral mucosa during use, improving comfort. The external protective block 95 prevents accidental swallowing of the oral component 93 by the patient and provides an external support point to increase stability and comfort. The intraoral soft suction block 96 features multiple suction holes 961 on its surface, ensuring gentle handling of the patient's oral mucosa during operation and reducing discomfort and the risk of injury. Furthermore, the oral component 93 is threadedly connected to the suction tube 91 via an installation tube 94 and a connector 92, making assembly and disassembly simple and quick, facilitating cleaning and replacement, and effectively preventing cross-infection. This is particularly suitable for situations requiring frequent equipment changes or cleaning.

[0033] In this embodiment, the fastener 8 includes a fixing plate 81, which is fixedly sleeved on the liquid collection pipe 7. One end of the liquid collection pipe 7 is fixedly connected to two support plates 82 that are symmetrically distributed vertically. The middle of each support plate 82 is threaded with an adjusting screw 83, and the opposite ends of each adjusting screw 83 are movably connected with a clamping block 84. The clamping block 84 has an arc-shaped structure, and the two clamping blocks 84 are symmetrically arranged vertically. The opposite ends of each clamping block 84 are fixedly connected with a rubber pad 85.

[0034] The above solution involves setting fasteners 8 on the collection pipe 7 and precisely controlling the distance between the two clamping blocks 84 by rotating the adjusting screw 83. This achieves a stable clamping of the suction pipe 91, improving the firmness and stability of the connection between the suction pipe 91 and the collection pipe 7, and preventing operational failures or interruptions due to loose connections. At the same time, setting rubber pads 85 on the surface of the clamping blocks 84 increases friction and provides a protective layer, preventing the suction pipe 91 from sliding and reducing its wear, extending the service life of the equipment, and improving the safety and reliability of the overall device.

[0035] In this embodiment, the bottom of the liquid collecting bottle 1 is integrally formed with a base 10, and the bottom area of ​​the base 10 is larger than the bottom area of ​​the liquid collecting bottle 1; an anti-overflow valve 41 is provided on the connecting pipe 4.

[0036] Through the above solutions: the base 10 significantly improves the stability of the entire device by increasing the contact area with the placement surface, avoiding liquid leakage or equipment damage due to tipping; the anti-overflow valve 41 ensures that liquid backflow will not occur even when the negative pressure is too high or the collection bottle 1 is full, increasing the safety of use.

[0037] It should be noted that this utility model is a medical oral continuous negative pressure suction device. During use, the medical oral continuous negative pressure suction device is first started. At this time, the vacuum negative pressure suction pump 5 starts to work, and generates a continuous negative pressure inside the collection bottle 1 through the connecting pipe 4. This negative pressure is transmitted to the collection pipe 7 through the connecting pipe 4, and then further reaches the oral component 93 through the suction pipe 91 in the suction body 9. Under the action of the soft suction block 96 in the mouth, secretions or blood in the oral cavity are sucked in through several suction holes 961 on its surface, and enter the collection bottle 1 for collection along the suction pipe 91 and the collection pipe 7. At the same time, the anti-overflow valve 41 ensures that no liquid backflow will occur even if the negative pressure is too large or the collection bottle 1 is full, which increases the safety of use.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
