Description

Technical Field

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

[0002] Saliva drainage is an important requirement in medical care and certain special scenarios. For example, for some patients after oral surgery, patients with specific neurological diseases that affect swallowing function, or people who are in a special position and bedridden for a long time, they cannot control the swallowing of saliva on their own. Excessive saliva accumulation in the mouth may cause serious complications such as choking and aspiration pneumonia, so effective saliva drainage measures are needed.

[0003] Traditional saliva drainage methods are often simple and extensive, usually using ordinary drainage tubes or cotton balls for adsorption, which lack adaptability to changes in patient position. In actual situations, patients may frequently change their side-lying direction, and traditional drainage devices cannot automatically adjust the drainage site according to the body position, which may lead to untimely or incomplete saliva drainage. When the patient lies on his side, more saliva tends to accumulate on the lower side of the mouth. If this side cannot be effectively drained, saliva may overflow, causing discomfort to the patient and increasing the difficulty and risk of care.

[0004] In addition, some existing drainage devices have obvious deficiencies in automation and intelligence. Most of them rely on manual observation and manual operation to adjust the drainage position, which not only increases the workload of medical staff, but also cannot guarantee the timeliness and accuracy of drainage, making it difficult to meet the requirements of modern medical care for comfortable patient care and efficient treatment.

[0005] In summary, the development of a device that can automatically and accurately drain unilateral saliva according to the patient's lateral lying direction has important practical significance and urgent clinical needs, which has also become the key problem that the present invention is committed to solving. Summary of the invention

[0006] The purpose of the present invention is to overcome the defects of the above-mentioned prior art and to provide a saliva drainage device which can automatically and accurately drain saliva on one side according to the patient's side-lying direction.

[0007] The purpose of the present invention can be achieved by the following technical solutions:

[0008] The invention provides a saliva drainage device, comprising a left cheek cotton piece, a first drainage tube, a first electromagnetic valve, a right cheek cotton piece, a second drainage tube, a second electromagnetic valve, a suction pump, a confluence pipe, a liquid storage bag and a controller.

[0013] A second drainage tube, one end of which is connected to the right cheek cotton piece;

[0014] A second solenoid valve, disposed on the second drainage pipe;

[0015] A suction pump connected to the other ends of the first drainage tube and the second drainage tube;

[0016] A manifold connected to the suction pump;

[0017] A liquid storage bag connected to the manifold;

[0018] The controller is respectively connected to the first gravity sensor, the second gravity sensor, the first solenoid valve, and the second solenoid valve for communicating with each other, and is used to instruct the first solenoid valve or the second solenoid valve to open according to the side-lying direction, so as to realize unilateral saliva drainage and suction.

[0019] Furthermore, adhesive is provided on one side of the liquid storage bag for attaching the liquid storage bag to a target position.

[0020] Furthermore, the first gravity sensor is glued and fixed in the left cheek cotton piece, and the outer surface of the first gravity sensor is encapsulated with a sealing film for waterproofing.

[0026] Furthermore, the suction pump is a peristaltic pump.

[0027] Furthermore, one end of the first drainage tube and the second drainage tube are respectively glued or sewed to the left cheek cotton piece and the right cheek cotton piece.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] The present invention provides a first gravity sensor and a second gravity sensor, which are respectively located on the left cheek cotton pad and the right cheek cotton pad, and can obtain the patient's side-lying direction. The controller can instruct the first solenoid valve or the second solenoid valve to open according to the side-lying direction information fed back by the gravity sensor, thereby realizing unilateral saliva drainage and suction. For example, when the patient lies on the left side, the controller can accurately control the opening of the corresponding solenoid valve on the left side to drain the saliva on the corresponding side; the same applies when lying on the right side. This intelligent control method can automatically adapt the drainage operation according to the changes in the patient's body position. Compared with traditional drainage devices without such automatic sensing control, it greatly improves the pertinence and accuracy of saliva drainage, and can effectively avoid unnecessary bilateral drainage or poor drainage.

[0031] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0034] Among them, a first gravity sensor is provided on the left cheek pad, and a second gravity sensor is provided on the right cheek pad, which are used to obtain the patient's side-lying direction. The first and second drainage tubes are connected to the left and right cheek pads respectively, and the first and second solenoid valves are provided on each pipeline. The suction pump is connected to the other end of the drainage tubes on both sides at the same time, and is connected to the liquid storage bag through the manifold. The controller is connected to each gravity sensor and the solenoid valve in communication, and can open the corresponding solenoid valve according to the side-lying direction instruction to achieve unilateral saliva drainage suction. In addition, there is adhesive on one side of the liquid storage bag for easy fixation, the gravity sensor has a waterproof sealing film and is equipped with a micro lithium battery, and the outer interlayer of the suction pump housing is equipped with a lithium battery to power the controller and related components. These components cooperate with each other to form a complete and innovative saliva drainage device system.

[0035] During the specific implementation, the following process is included: the left cheek cotton piece 1 is used to stick to the left cheek mucosa, and the left cheek cotton piece 1 is provided with a first gravity sensor 2, and the first gravity sensor 2 is used to obtain the patient's side-lying direction; a first drainage tube 3, one end of which is connected to the left cheek cotton piece 1; a first solenoid valve 4 is provided on the first drainage tube 3; a right cheek cotton piece 5 is used to stick to the right cheek mucosa, and the right cheek cotton piece 4 is provided with a second gravity sensor 6, and the second gravity sensor 6 is used to obtain the patient's side-lying direction; a second drainage tube 7, one end of which is connected to the left cheek cotton piece 1; a first solenoid valve 4 is provided on the first drainage tube 3; One end is connected to the right cheek cotton piece 5; the second solenoid valve 10 is arranged on the second drainage tube 7; the suction pump 8 is connected to the other ends of the first drainage tube 3 and the second drainage tube 7 at the same time; the manifold 11 is connected to the suction pump 8; the liquid storage bag 12 is connected to the manifold 11; the controller 9 is respectively communicated with the first gravity sensor 2, the second gravity sensor 6, the first solenoid valve 4, and the second solenoid valve 10, and is used to instruct the first solenoid valve 4 or the second solenoid valve 10 to open according to the side-lying direction, so as to realize unilateral saliva drainage and suction.

[0036] The logic of the gravity sensor obtaining the patient's side-lying direction is the existing technology of the personnel in this field. The logic of the controller 9 obtaining the output signal of the gravity sensor and instructing the corresponding solenoid valve to open and close is also a common technical means of the personnel in this field, which will not be repeated here.

[0037] Adhesive is provided on one side of the liquid storage bag 12 for attaching the liquid storage bag 12 to a target position.

[0038] The first gravity sensor 2 is glued and fixed in the left cheek cotton sheet 1, and a sealing film for waterproofing is encapsulated on the outer surface of the first gravity sensor 2. The second gravity sensor 6 is glued and fixed in the right cheek cotton sheet 1, and a sealing film for waterproofing is encapsulated on the outer surface of the second gravity sensor 6. The first gravity sensor 2 and the second gravity sensor 6 are both equipped with miniature lithium batteries.

[0039] The controller 9 is a single-chip microcomputer, and the model of the single-chip microcomputer can be any model commonly used by people in this field. An outer interlayer is provided on the shell of the suction pump 8, and the controller 9 is fixed in the outer interlayer. A lithium battery is also provided in the outer interlayer, which is used to power the controller 9, the first solenoid valve 4, the second solenoid valve 10, and the suction pump 8. The suction pump 8 is a peristaltic pump. One end of the first drainage tube 3 and the second drainage tube 7 are respectively glued or sewn to the left cheek cotton sheet 1 and the right cheek cotton sheet 5. The electrical connection relationship involved in this technical solution is simple, and it is extremely easy to implement according to those skilled in the art, and Figure 1 The communication connection or electrical connection relationship has been shown by the dotted lines and will not be repeated here.

[0040] The overall structure of the bilateral cheek pads and drainage tubes: The left cheek pad and the right cheek pad are connected to the first drainage tube and the second drainage tube respectively. The bilateral setting can meet the patient's saliva collection needs in different side-lying directions, and can fully cover the parts where saliva may flow out in different body positions to ensure the comprehensiveness of drainage. In addition, one end of the drainage tube is firmly connected to the cheek pad (fixed by gluing or sewing), and the other end is connected to the suction pump, constructing a complete and reliable saliva drainage channel to ensure that saliva can be smoothly drained from the oral area to the subsequent conduit and liquid storage bag.

[0041] Reasonable layout of suction pump, manifold and liquid storage bag: The suction pump is connected to the drainage tubes on both sides at the same time, which plays a key role in extracting saliva and providing drainage power. The extracted saliva is then collected through the manifold and finally introduced into the liquid storage bag for storage. One side of the liquid storage bag is provided with adhesive to facilitate sticking to the target position, which is convenient for placing and fixing the liquid collected by the entire drainage device, making the overall structure compact and practical, forming an orderly and efficient process system from drainage to storage.

[0042] Detail optimization and innovation

[0043] Packaging and power supply guarantee of gravity sensor: The first gravity sensor and the second gravity sensor are not only glued and fixed in the cheek cotton sheet, but also have waterproof sealing films on their outer surfaces, which can effectively prevent saliva and other liquids in the mouth from damaging them and ensure their normal operation in a humid oral environment. At the same time, the gravity sensor is matched with a micro lithium battery for power supply to ensure its stable operation, further enhancing the reliability and durability of the entire device in actual use.

[0044] Layout and power supply of the controller and related components: The controller uses a single-chip microcomputer, which has good control performance and applicability. The controller is fixed in the outer interlayer of the suction pump housing, which makes rational use of space and makes the device structure more compact. In addition, a lithium battery is also provided in the outer interlayer to provide unified power supply for the controller, solenoid valve and suction pump. This centralized power supply and reasonable layout of the power supply reduces the complexity of wiring and improves the integration and portability of the entire device.

[0045] Reasonable selection of suction pump type: The suction pump uses a peristaltic pump. The peristaltic pump has the characteristics of good sealing, precise flow control and small shear force on the fluid. It is very suitable for drainage scenarios of relatively viscous liquids with small flow rates such as saliva. It can smoothly and accurately achieve saliva suction and ensure drainage effect.

[0046] The above description of the embodiments is to facilitate the understanding and use of the invention by those skilled in the art. It is obvious that those skilled in the art can easily make various modifications to these embodiments and apply the general principles described herein to other embodiments without creative work. Therefore, the present invention is not limited to the above embodiments, and improvements and modifications made by those skilled in the art based on the disclosure of the present invention without departing from the scope of the present invention should be within the scope of protection of the present invention.
