[0032] The exemplary embodiments will be described in detail herein with reference to the accompanying drawings. In the following description, unless otherwise indicated, like numbers in the different drawings represent the same or similar elements. The following exemplary embodiments described therein represent the best known uses of the application at the time of development. However, these embodiments are merely examples of apparatuses and methods in accordance with some aspects of the application as detailed in the attached claims.
[0033] To solve the problems in the related art, the application provides a drainage and flushing device. The drainage and flushing device comprises a support and a negative pressure tube. The negative pressure tube is arranged between a top wall and a bottom wall of the support. A first end of the top wall is provided with an arc-shaped plate. An end of the arc-shaped plate away from the top wall is bent towards the bottom wall. In a use state, the first end of the top wall extends into an oral cavity of a patient. A side of the arc-shaped plate away from the bottom wall is used to contact the palate of the oral cavity. In the embodiment, the side of the arc-shaped plate away from the bottom wall on the top wall of the support can contact the palate of the oral cavity of the patient. Thus, the support is supported and fixed, so that the user licking the support cannot cause the position of the support to deviate and cannot normally suck off the secretion at a specific position. This is beneficial to improving the drainage and flushing effect.
[0034] According to an exemplary embodiment of the application, as shown in Figure 1 The application provides a drainage and flushing device for collecting and draining secretion in the oral cavity of a critically ill patient. The drainage and flushing device for collecting and draining secretion in the oral cavity of a critically ill patient can extend into the oral cavity of the critically ill patient and drain the secretion in the oral cavity to the outside of the oral cavity by means of negative pressure, so as to avoid the secretion breeding bacteria in the oral cavity to infect the patient. The secretion in the oral cavity is, for example, saliva, sputum, etc.
[0035] As shown in Figure 1 and Figure 2 The drainage and flushing device for collecting and draining secretion in the oral cavity of a critically ill patient comprises a support 100 and a negative pressure tube 200. The support 100 comprises opposite top and bottom walls 10 and 20. The negative pressure tube 200 is connected to the support 100 and located between the top and bottom walls 10 and 20. In a use state, the top and bottom walls 10 and 20 of the support 100 abut the upper and lower teeth of the user, respectively, so as to avoid the negative pressure tube 200 being unable to normally drain the secretion under pressure.
[0036] Referring to Figure 1 andFigure 2 One end of the support 100 is inserted into the oral cavity, while the other end remains outside the oral cavity. (Continue reading...) Figure 1 and Figure 2 An arc-shaped plate 11 is provided at the first end of the top wall 10 of the bracket 100, along the length direction of the bracket 100. Figure 1 As shown in the x-direction, the end of the curved plate 11 furthest from the top wall 10 bends towards the bottom wall 20, and the side of the curved plate 11 facing away from the bottom wall 20 is used to contact the patient's palate. It is understood that the curved plate 11 can contact the palate to support and fix the support 100, preventing the user from licking the support 100 and causing it to shift position, thus preventing proper suctioning of secretions from specific locations. This embodiment does not impose excessive limitations on the specific dimensional parameters of the curved plate 11; for example, a specific size of curved plate 11 can be selected based on the user's age.
[0037] In this embodiment, the side of the arc-shaped plate 11 on the top wall 10 of the stent 100 that is opposite to the bottom wall 20 can contact the patient's palate, thereby supporting and fixing the stent 100 to prevent the user from licking the stent 100, which would cause the stent 100 to shift position and fail to properly remove secretions from specific locations, thus improving the drainage and flushing effect.
[0038] In one exemplary embodiment, such as Figure 1 and Figure 2 As shown, this embodiment provides a device for collecting, draining, and rinsing oral secretions in critically ill patients. The device includes a support 100 and a negative pressure tube 200. The negative pressure tube 200 is disposed between the top wall 10 and the bottom wall 20 of the support 100.

In use, the first end of the top wall 10 extends into the patient's oral cavity, and the side of the arc-shaped plate 11 facing away from the bottom wall 20 is used to contact the palate.
[0039] Among them, such as Figure 1 As shown, the curved plate 11 has an elastic structure. The elastic curved plate 11 allows for better contact with the palate and prevents hard objects from injuring the palate when the oral secretion collection and drainage irrigation device is placed in the mouth of critically ill patients, thus optimizing the patient's experience. The curved plate 11 can be made of materials such as rubber or silicone.
[0040] Among them, such as Figure 2 As shown, a sector-shaped plate 21 is provided at the first end of the bottom wall 20 of the bracket 100. The sector-shaped plate 21 is configured such that, along the direction away from the bottom wall 20, the width of the sector-shaped plate 21 is ( Figure 1The width of the bottom wall 20 gradually increases along the y direction shown in FIG. 2. In use, the bottom wall 20 of the fan-shaped plate 21 is used to contact the upper surface of the tongue of a patient to provide reliable support for the bracket 100, so as to avoid the position of the oral secretion collection and drainage flushing device from being deviated due to the collection of oral secretions of a critical patient. For example, refer to Figure 1 The width of the position where the fan-shaped plate 21 is connected with the bottom wall 20 is the same as the width of the bottom wall 20, and the connection position has a rounded corner. In an alternative embodiment, the fan-shaped plate 21 and the bottom wall 20 are integrated.
