Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a sputum suction tube for preventing accidental aspiration. Background Art

[0002] Sputum suction refers to a method of sucking out respiratory secretions through the oral cavity, nasal cavity, and artificial airway to keep the respiratory tract unobstructed and prevent complications such as aspiration pneumonia, atelectasis, and suffocation. It is suitable for patients in coma, patients with a lot of sputum who may suffocate, patients who need intratracheal medication, contrast agent injection, or sputum dilution. Contraindications are that nasal catheter suction is prohibited for patients with skull base fractures. Patients with endotracheal intubation or tracheotomy cannot spit actively, and patients often need sputum suction when spitting. Patients with lung infections also need sputum suction when spitting. When suctioning sputum, a suction tube is generally used. The outer wall of the suction tube is smooth, and a joint and a switch are provided on the suction tube. After one end of the suction tube is inserted into the trachea, the other end is connected to a negative pressure generating device to use negative pressure to suction sputum. In the prior art, the suction tube has a simple structure and can only be used for suctioning sputum. When the patient's oral cavity, nasal cavity, and respiratory tract are accumulated with sputum or saliva for a long time, it is easy to cause adverse consequences such as false suction and infection of the patient.

[0003] To this end, the prior art provides many solutions, such as providing an airbag structure on the intubation device to solve the problem of aspiration. For example, the existing patent CA2871922A1 provides a sputum suction device, which includes a suction pipeline, a switching unit, a measuring unit and a control unit. The suction pipeline has a suction port and a receiving portion, and the receiving portion receives the sucked sputum and maintains a negative pressure. The switching unit can switch between a first state and a second state. The first state connects the suction port to the receiving portion. The second state separates the suction port from the receiving portion. The switching unit is placed in the suction pipeline. In the first state, the measuring unit measures the exhaled air sucked into the receiving portion, but the above technical solution still has no better solution for the patient's oral fluid accumulation. Summary of the invention

[0004] The purpose of the present invention is to provide a sputum suction tube that prevents accidental aspiration, which can solve the problems of liquid accumulation in the patient's mouth and foreign objects in the mouth, avoid choking and suffocation caused by accidental aspiration, and reduce the mortality rate of critically ill patients.

[0005] In order to solve the above technical problems, the present invention specifically provides the following technical solutions: a sputum suction tube for preventing accidental aspiration, comprising a plug body, the plug body is connected to a first tube portion that can be placed in the airway, the plug body is connected to a liquid collecting piece placed in the oral cavity, the plug body is provided with a second tube body connected to the liquid collecting piece, the connecting end of the second tube body is connected to a second bottle body, and the second bottle body is connected to a pump body. The present invention provides a plug body that can serve as a base for placing the first tube part to intubate the patient's airway. The plug body is used to limit the patient's oral teeth from biting the first tube part, causing the first tube part to deform and form a contact gap with the airway wall, so as to prevent gastric liquid / object reflux from causing aspiration. At the same time, a liquid collecting piece is provided to solve the problem of sputum and saliva in the patient's mouth. The medium in the oral cavity is collected into the second bottle body, which is conducive to distinguishing the amount of sputum collected in the oral cavity and the first tube part for the doctor to judge. On the one hand, it solves the potential risk of aspiration of the medium in the patient's mouth. On the other hand, by providing a liquid collecting piece at the patient's mouth, the space in the patient's mouth is appropriately filled, so that the patient's teeth have a bite contact object, reducing the probability of the teeth biting the first tube part and providing a basis for the appropriate bite movement of the teeth, which has an effect of reducing the discomfort inside the patient's mouth.

[0006] According to one embodiment of the present invention, the first tube portion is connected to the second tube portion connected thereto, the end of the second tube portion is connected to the first bottle body, and the first bottle body is connected to the pump body. The pump body is used to form a negative pressure inside the first bottle body so as to suck sputum into the first bottle body. The sucked sputum can assist doctors in judging the patient's condition.

[0007] According to an embodiment of the present invention, an air bag is provided on the first tube part, and an air pump connected to the air bag is provided on the second tube part. The air bag is used to prevent oropharyngeal secretions or refluxed gastric contents from entering the lungs through the airway.

[0008] According to one embodiment of the present invention, the liquid collection piece includes a first sleeve, the interior of the first sleeve is connected to the second sleeve by a connecting plate, the first sleeve and the second sleeve are both provided with a first through hole on their surfaces, and the first sleeve and the second sleeve are provided with a spacing distance, so that the patient's mouth can perform appropriate biting movements to relieve oral muscle fatigue. The first sleeve and the second sleeve can control the range of their extrusion and deformation, and then control the amplitude of the patient's bite. When the first sleeve and the second sleeve are deformed by external force, negative pressure can be formed inside, which has the effect of pre-collecting liquid and foreign matter in the patient's mouth, such as pre-collecting food residues in the patient's mouth, and using a double-layer structure to squeeze and damage the pre-collected objects, which is convenient for subsequent suction to prevent blockage. The liquid can enter the first sleeve and the second sleeve through the first through hole, thereby transferring the position of the liquid inside the patient's mouth to prevent the patient from aspirating by mistake.

[0009] According to one embodiment of the present invention, annular strips are arranged at intervals on the surface of the first sleeve to reduce the probability of the liquid collection piece moving in the patient's mouth, specifically increasing the contact surface between the first sleeve surface and the oral cavity to reduce the probability of the first sleeve sliding too much in the oral cavity.

[0010] According to one embodiment of the present invention, the plug body has a column sleeve that can be plugged into the first tube part, the end of the column sleeve has a flexible plate, the side of the column sleeve is provided with a second interface that can communicate with the interior thereof, the flexible plate is provided with a first interface, one end of the first interface is connected to the liquid collecting piece, and the other end is connected to the second tube body. The present invention can intubate the patient's airway by setting the plug body as a base for placing the first tube part, and use the plug body to restrict the patient's oral teeth from biting the first tube part. The plug body provided in addition is used to connect with an external line or tube body, that is, specifically, the first interface and the second interface connection pipeline are regulated, the external device is concentrated on the outside of the patient's mouth, and is reasonably regulated to reserve an effective observation space for the patient's mouth, so that medical staff can observe whether the patient has any abnormality.

[0011] According to one embodiment of the present invention, a filter element is provided on the second tube body, and the filter element includes a filter sleeve of a columnar structure, a limiting ring is provided on the end of the filter sleeve, a filter plate is provided around the inner side of the limiting ring, the end of the filter plate is bent toward the center of the limiting ring, at least one sphere is placed between the filter plates, one end of the filter sleeve can be connected to the second tube body or the first interface, and the other end of the filter sleeve is provided with a connecting tube body, which can be connected to the second tube body or the second bottle body. The filter element is specifically provided to filter the medium flowing through the filter plate inside the filter sleeve to prevent foreign matter from blocking the entire second tube body and causing difficulty in sucking liquid from the patient's mouth. The sphere is provided to automatically squeeze the sphere to control the adjacent spacing of the filter plates according to the filtering situation, so as to ensure the flow path of the filter medium. Based on this, the gap between the filter plates and the situation of the second tube body filtering the medium can be used to warn whether there are foreign matter in the patient's mouth or even whether there is gastric reflux.

[0012] According to an embodiment of the present invention, the pump body is connected to a first controller for controlling the pump body, and the first controller is connected to an industrial computer. The industrial computer is also connected to the air pump to control the start and stop of the air pump.

[0013] Compared with the prior art, the present invention has the following beneficial effects: the present invention provides a plug body that can serve as a base for placing the first tube portion to intubate the patient's airway, and uses the plug body to restrict the patient's oral teeth from biting the first tube portion, causing the first tube portion to deform and resulting in a contact gap with the airway wall, so as to prevent the reflux of gastric substances from causing aspiration, and at the same time, a liquid collection piece is provided to solve the problem of sputum and saliva in the patient's mouth, and the medium in the oral cavity is collected into the second bottle body, which is conducive to distinguishing the amount of sputum collected in the oral cavity and the first tube portion for the doctor to judge.

The present invention provides a plug body 13 that can serve as a base for placing the first tube part 10 to intubate the patient's airway. The plug body 13 is used to limit the patient's oral teeth from biting the first tube part 10, causing the first tube part to deform and resulting in a contact gap with the airway wall, so as to prevent gastric liquid / object reflux from causing aspiration. At the same time, a liquid collecting piece 40 is provided to solve the problem of sputum and saliva in the patient's mouth, and the medium in the oral cavity is collected into the second bottle body 24 to facilitate the distinction between the amount of sputum collected in the oral cavity and the first tube part 10 for the doctor to judge. On the one hand, it solves the potential risk of aspiration of the medium in the patient's mouth. On the other hand, by providing the liquid collecting piece 40 in the patient's mouth, the patient's oral space is appropriately filled, so that the patient's teeth have a bite contact object, reducing the probability of the teeth biting the first tube part 10 and providing a basis for the appropriate bite movement of the teeth, which has an effect of reducing the discomfort inside the patient's mouth.

[0028] The first tube portion 10 is connected to the second tube portion 20 which is in communication therewith. The end of the second tube portion 20 is connected to the first bottle body 22. The first bottle body 22 is connected to the pump body 32. The pump body 32 is used to form a negative pressure inside the first bottle body 22 so that sputum is sucked into the first bottle body 22. The sucked sputum can assist doctors in judging the patient's condition.

[0029] The first tube 11 is provided with an air bag 11, and the second tube 20 is provided with an air pump 33 connected to the air bag 11. The air bag 11 is used to prevent oropharyngeal secretions or refluxed gastric contents from entering the lungs through the airway. In this embodiment, a pressure sensor can be provided inside the air bag 11 and connected to an external device to monitor the internal pressure of the air bag 11 to prevent the air bag 11 from leaking and failing to respond to the patient in time.

[0030] The liquid collecting member 40 includes a first sleeve 41, and the interior of the first sleeve 41 is connected to the second sleeve 44 through a connecting plate 45. The surfaces of the first sleeve 41 and the second sleeve 44 are both provided with a first through hole 43. The first sleeve 41 and the second sleeve 44 are provided with a spacing distance, so that the patient's mouth can perform appropriate biting exercises to relieve oral muscle fatigue. The first sleeve 41 and the second sleeve 44 can control the range of their extrusion and deformation, and then control the amplitude of the patient's bite. When the first sleeve 41 and the second sleeve 44 are deformed by external force, negative pressure can be formed inside, which has the effect of pre-collecting liquid and foreign matter in the patient's mouth, such as pre-collecting food residues in the patient's mouth, and using a double-layer structure to squeeze and damage the pre-collected objects, so as to facilitate subsequent suction and prevent blockage. The liquid can enter the first sleeve 41 and the second sleeve 44 through the first through hole 43, so as to transfer the position of the liquid inside the patient's mouth to prevent the patient from aspirating by mistake.

[0031] Annular strips 42 are arranged at intervals on the surface of the first sleeve 41 to reduce the probability of the liquid collecting member 40 moving in the patient's mouth. Specifically, the contact surface between the first sleeve 41 and the oral cavity is increased to reduce the probability of the first sleeve 41 sliding too much in the oral cavity.

[0032] The plug body 13 has a column sleeve that can be plugged into the first tube part 10, and the end of the column sleeve has a flexible plate. The side of the column sleeve is provided with a second interface 132 that can communicate with the inside thereof, and the flexible plate is provided with a first interface 131, one end of the first interface 131 is connected to the liquid collecting member 40, and the other end is connected to the second tube body 24. The present invention can be used as a base for placing the first tube part 10 to intubate the patient's airway by setting the plug body 13, and the plug body 13 is used to limit the patient's oral teeth from biting the first tube part 10. The plug body 13 is also provided for connecting with an external line or tube body, that is, specifically, the first interface 131 and the second interface 132 are connected to the pipeline, and the external device is concentrated on the outside of the patient's mouth, and is reasonably regulated to reserve an effective observation space for the patient's mouth, so that medical staff can observe whether the patient has any abnormality.

[0033] The material of the liquid collecting piece 40 is preferably made of medical silicone rubber. The liquid collecting piece 40 is soft and non-irritating, and each component is rounded. The liquid collecting piece 40 in this embodiment is disposable to avoid the risk of pathogen infection when used alternately by patients.

[0034] The first tube portion 10 is soft and non-irritating, and the front end of the tube is rounded to prevent respiratory tract damage and bleeding during intubation, greatly alleviating the patient's pain. The first tube portion 10 is treated with an ultra-slip process and is very smooth, making intubation easier and more convenient. The tube body of the first tube portion 10 is printed with scales to make it easier to learn to grasp the intubation depth.

[0035] It should be noted that the plug body 13 can be equipped with corresponding extensions according to different departments or patient conditions so that medical staff can distinguish and handle them.

[0036] A filter element is provided on the second tube body 24, and the filter element includes a filter sleeve 136 of a columnar structure. A limiting ring 134 is sleeved on the end of the filter sleeve 136. A filter plate 135 is arranged around the inner side of the limiting ring 134. The end of the filter plate 135 is bent toward the center of the limiting ring 134. At least one sphere 133 is placed between the filter plates 135. One end of the filter sleeve 136 can be connected to the second tube body 24 or the first interface 131. The other end of the filter sleeve 136 is provided with a connecting tube body 137. The connecting tube body 137 can be connected to the second tube body 24 or the second bottle body 23. The filter element is specifically used to filter the medium flowing through the filter plate 135 inside the filter sleeve 136 to prevent foreign matter from clogging the entire second tube body 24 and causing difficulty in sucking liquid from the patient's mouth. The ball 133 is provided to automatically squeeze the ball 133 according to the filtering situation to control the adjacent spacing of the filter plate 135 to ensure the flow path of the filtered medium. Based on this, the gap between the filter plate 135 and the medium extraction situation of the second tube body 24 can be used to warn the patient whether there is foreign matter in the mouth of the patient or even whether gastric reflux problems occur.

[0037] The pump body 32 is connected to a first controller 31 for controlling the pump body 32, and the first controller 31 is connected to an industrial computer 30. The industrial computer 30 is also connected to an air pump 33 to control the start and stop of the air pump 33. It should be noted that the negative pressure of sputum suction is specifically adjusted according to the age and condition of the patient, and the setting of negative pressure is not provided. Therefore, the industrial computer 30 needs to be set to control the individual components, such as the first controller 31 and the air pump 33.

[0038] Embodiment 2:

[0039] Compared with the solution of Example 1, this embodiment further improves the solution as follows: Figure 7As shown, the inner wall of the second tube portion 20 has a second annular tube body, and the second annular tube body separates the tube body structure of the second tube portion 20 into an inner tube body and an air pipe 16. A first opening 14 is opened on the second tube portion 20 of the air pipe 16, and an air bag 11 is arranged on the outer side of the second tube portion 20 where the first opening 14 is arranged. A rubber plug 18 and a sliding sleeve 15 are arranged on the inner wall of the air pipe 16. The rubber plug 18 and the sliding sleeve 15 are respectively arranged on both sides of the first opening 14. The rubber plug 18 and the sliding sleeve 15 are connected by a first spring 17. The sliding sleeve 15 can slide relative to the air pipe 16 to seal the first opening 14. Both ends of the sliding sleeve 15 are sealed, and the sliding sleeve 15 can slide relative to the air pipe 16.

[0040] The airbag 11 is capable of filling the gap between the first tube portion 10 and the patient's airway wall, thereby preventing oropharyngeal secretions or refluxed gastric contents from entering the lungs through the airway. On this basis, the airbag 11 needs to be filled with sufficient gas through an external air pump 33 to ensure effective contact between the airbag 11 and the patient's airway wall. The trachea 16 provided in the scheme of the present invention can realize the connection between the air pump 33 and the airbag 11, and at the same time, a first opening 14 connected to the trachea 16 is provided on the second tube portion 20, thereby realizing the control of the expansion of the airbag 11.

[0041] A further solution of arranging a rubber plug 18 and a sliding sleeve 15 in the trachea 16 is used to control the blocking of the first opening 14. During inflation, air pressure is used to push the sliding sleeve 15 to move relative to the trachea 16, and the trachea 16 and the first opening 14 are connected to inflate the airbag 11. After the inflation is completed, the reduction in air pressure causes the sliding sleeve 15 to slide under the push of the first spring 17, thereby ensuring the overall filling state of the airbag 11, and reserving space between the sliding sleeve 15 and the rubber plug 18 to provide deformation range control for the airbag 11, so that the airbag 11 can have a certain deformation and always fit with the expansion and contraction of the muscle tissue of the patient's airway wall, thereby solving the problem of airway edema caused by the continuous high-pressure expansion state of the airbag 11.
