Description

Technical Field

[0001] This utility model relates to the field of medical supplies technology, specifically a saliva suction device for patients with oral intubation. Background Technology

[0002] In the care of patients with oral intubation, retention of oral secretions (saliva) is a significant contributing factor to aspiration pneumonia, catheter obstruction, and patient discomfort. Statistics show that oral intubation patients secrete 500–1500 ml of saliva daily. Traditional methods of managing this have significant drawbacks: disposable suction catheters are commonly used to directly aspirate saliva, but these have issues such as excessively large diameters (the average width of the oral vestibule is only 18–22 mm) and hard materials, leading to a high rate of mucosal damage; the negative pressure adjustment range is mismatched with the viscosity of saliva, easily causing tissue damage or incomplete aspiration; traditional procedures require manual holding of the suction catheter for repeated aspiration, with each session taking an average of 8–12 minutes, and nurses performing 20–30 procedures daily; the lack of a fixation device results in a high rate of catheter displacement, requiring frequent adjustments and increasing the risk of cross-infection; mechanically ventilated patients require ventilation to be paused for aspiration, increasing the probability of a drop in blood oxygen saturation; agitated patients require two-person operation, consuming medical resources. Utility Model Content

[0003] In view of the shortcomings of the prior art, a saliva suction device for patients with oral intubation is provided, which can be used with the occlusal pad of the oral intubation tube to perform saliva suction operation. The saliva suction operation is convenient, reduces damage to the oral mucosa, and reduces the intensity of nursing care.

[0004] To achieve the above-mentioned objectives and other related objectives, this utility model proposes... A saliva suction device for patients with oral intubation, comprising: A bite pad is inserted into the patient's mouth. An oral intubation tube is fixed to the occlusal pad and inserted into the patient's oral airway; A suction tube is installed on the occlusal pad and can be slidably adjusted on the occlusal pad. The suction tube opening extending out of the occlusal pad is connected to a negative pressure suction device, and a suction operation is performed on the suction tube. A counterweight is installed at the end of the suction tube, allowing the suction tube to move and fall into the oral cavity while positioned on the occlusal pad. The negative pressure suction device is then activated to perform suction of saliva from the oral cavity.

[0005] In one embodiment of this utility model, the occlusal pad is made of flexible silicone and is generally arc-shaped. The occlusal pad has slots on both the inner and outer sides for engaging the oral cannula and is arranged through the occlusal pad along its length.

[0006] In one embodiment of the present invention, both the inner and outer sides of the biting pad are provided with biting grooves, and multiple sets of biting grooves are arranged at intervals along the length of the biting pad.

[0007] In one embodiment of the present invention, the occlusal pad is provided with a through hole, the through hole is arranged through the length of the occlusal pad, and the suction tube is located inside the through hole.

[0008] In one embodiment of this utility model, an enlarged cavity is provided at the opening of the through hole, and the counterweight and the enlarged cavity are engaged or disengaged.

[0009] In one embodiment of the present invention, the outer wall of the suction tube is provided with a protrusion, the counterweight is provided with an annular groove, the counterweight is sleeved on the outer wall of the tube end of the suction tube, and the protrusion and the annular groove cooperate with each other.

[0010] In one embodiment of the present invention, one end of the suction tube extends out of the counterweight, and the end of the suction tube is arranged in a constricted shape.

[0011] In one embodiment of this utility model, a gasket is slidably sleeved on the suction tube, and the two sides of the gasket abut against the counterweight and the bottom of the enlarged cavity.

[0012] In one embodiment of this utility model, the other end of the suction tube extending out of the through hole is provided with a threaded section, and a fixing adjustment cap is provided on the threaded section. The fixing adjustment cap abuts against or separates from one end of the engagement pad.

[0013] By adopting the above technical solution, the technical effect of this utility model is as follows: through the gravity-coordinated design of the counterweight and the suction tube, the end of the suction tube can automatically conform to the oral anatomical structure (such as the tongue floor and posterior pharyngeal wall), and can cover hidden areas that are difficult to reach by traditional equipment (such as the piriform crypt) without manual adjustment, thereby increasing the effective suction area.

Detailed Implementation

[0016] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0017] It should be noted that the illustrations provided in this embodiment are only schematic representations of the basic concept of this utility model. Therefore, the drawings only show the components related to this utility model and are not drawn according to the actual number, shape and size of the components. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0018] Disposable suction catheters are commonly used in clinical practice to directly aspirate saliva, but they have drawbacks such as excessively large diameter and rigid materials, leading to a high rate of mucosal damage. The negative pressure adjustment range is mismatched with the viscosity of saliva, easily causing tissue damage or incomplete aspiration. Traditional procedures require manual holding of the suction catheter for repeated aspiration, and the lack of a fixing device results in a high rate of catheter displacement, requiring frequent adjustments and increasing the risk of cross-infection. Furthermore, mechanically ventilated patients require ventilation to be paused for aspiration, increasing the probability of a significant drop in blood oxygen saturation. Additionally, agitated patients may require two-person operation, consuming medical resources. To address these issues, a saliva aspirator for patients with oral intubation is proposed, comprising: an occlusal pad 10. The oral cannula 20 is used to fix the oral cannula 20 and extend into the patient's oral cavity; the oral cannula 20 is fixed on the occlusal pad 10 and extends into the patient's oral airway; the suction tube 30 is installed on the occlusal pad 10 and can slide and adjust on the occlusal pad 10, the opening of the suction tube 30 extending out of the occlusal pad 10 is connected to the negative pressure suction device, and the suction tube 30 is used to perform suction operation; the counterweight 40 is installed at the end of the suction tube 30, and allows the suction tube 30 to move on the occlusal pad 10 and fall into the oral cavity, and the negative pressure suction device is activated to perform suction operation of saliva in the oral cavity.

[0019] In one embodiment, see Figure 3 and Figure 6 As shown, a counterweight 40 is provided on the suction tube 30. When it is necessary to aspirate saliva from the patient's mouth, the suction tube 30 is released. Under the gravity of the counterweight 40, the suction tube 30 falls into the mouth and can adaptively fall into a more hidden area, such as the piriform crypt, thereby activating the negative pressure suction device to aspirate saliva from the patient's mouth.

[0020] In one embodiment, the counterweight 40 may be made of smooth ceramic or food-grade silicone, which allows the suction tube 30 to fall into the oral cavity to suction saliva from hidden areas of the oral cavity.

[0021] In one embodiment, the occlusal pad 10 may be made of food-grade silicone with a Shore hardness of around 30A to avoid causing mechanical abrasion to the patient's oral cavity.

[0022] In one embodiment, the occlusal pad 10 is generally arc-shaped, and its main outline matches the anatomical structure of the human oral cavity, making the patient more comfortable when actually biting.

[0023] In one embodiment, slots 11 are provided on both the inner and outer sides of the occlusal pad 10. The slots 11 are used to engage the oral insertion tube 20 and are arranged through the occlusal pad 10 along its length.

[0024] The occlusal pad 10 has slots 11 on both its inner and outer sides, which can be used to restrict and fix the oral insertion tube 20 according to actual use.

[0025] In one embodiment, to prevent the occlusal pad from stably occluding with the patient's teeth, occlusal grooves 12 are provided on both the inner and outer sides of the occlusal pad 10, and multiple sets of occlusal grooves 12 are arranged at intervals along the length of the occlusal pad 10.

[0026] In one embodiment, to install the suction tube 30, the occlusal pad 10 is provided with a through hole 13, which is arranged through the length of the occlusal pad 10. The suction tube 30 is located in the through hole 13 and can be pulled out within the through hole 13. When suction is needed, the suction tube 30 is released. When suction is not needed, the suction tube 30 is raised so that the counterweight 40 abuts against one end of the occlusal pad 10, avoiding discomfort caused by the counterweight 40 being located at the bottom of the patient's mouth.

[0027] In one embodiment, see Figure 4 In order to allow the counterweight 40 to be accommodated in the through hole 13, an enlarged cavity 131 is provided at the opening of the through hole 13, and the counterweight 40 and the enlarged cavity 131 are engaged or disengaged.

[0028] In one embodiment, the contour of the enlarged cavity 131 is consistent with the outer contour of the counterweight 40. When it is not necessary to aspirate the patient's saliva, the counterweight 40 is placed inside the enlarged cavity 131 by pulling the suction tube 30, thereby avoiding the discomfort caused by the counterweight 40 falling into the oral cavity.

[0029] In one embodiment, see Figures 5 to 7 To achieve the connection between the counterweight 40 and the suction tube 30, the outer wall of the suction tube 30 is provided with a protrusion 31, and the counterweight 40 is provided with an annular groove 41. The counterweight 40 is sleeved on the outer wall of the tube end of the suction tube 30, and the protrusion 31 and the annular groove 41 cooperate.

[0030] In one embodiment, one end of the suction tube 30 extends out of the counterweight 40, and the end of the suction tube 30 is arranged in a constricted shape.

[0031] In one embodiment, a gasket 32 ​​is slidably sleeved on the suction tube 30, and the two sides of the gasket 32 ​​abut against the counterweight 40 and the bottom of the enlarged cavity 131.

[0032] In one embodiment, the suction tube 30 extends out of the through hole 13 and has a threaded section at the other end. A fixing adjustment cap 34 is provided on the threaded section, and the fixing adjustment cap 34 abuts against or separates from one end of the engagement pad 10.

[0033] In actual use, when suction is not required, the caregiver holds the suction tube 30 and rotates the fixing adjustment cap 34 so that the fixing adjustment cap 34 abuts against one end of the occlusal pad 10, thereby allowing the suction tube 30 to be pulled out from the through hole 13 until the counterweight 40 is located in the enlarged cavity 131; when saliva needs to be suctioned, the fixing adjustment cap 34 is rotated in the opposite direction so that the fixing adjustment cap 34 separates from the threaded section. Under the action of the counterweight 40, the suction tube can fall into a hidden area of ​​the oral cavity, and the negative pressure suction device is activated to achieve suction of saliva in the oral cavity.

[0034] Therefore, through the gravity-coordinated design of the counterweight 40 and the suction tube 30, the end of the suction tube 30 can automatically conform to the oral anatomical structure (such as the tongue floor and posterior pharyngeal wall), and can cover hidden areas that are difficult to reach by traditional devices (such as the piriform crypt) without manual adjustment, thereby increasing the effective suction area.

[0035] The above description is only a preferred embodiment of this application and an explanation of the technical principles used. Those skilled in the art should understand that the scope involved in this application is not limited to the technical solutions formed by a specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the inventive concept.
