Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an oral irrigation and suction device with an adjustable angle. Background Technology

[0002] In existing technology, Swiftsure's Swishkit kit uses a combination of a water inlet (rinsing end) and a suction end to insert into both sides of the patient's mouth, rinsing the oral cavity and aspirating the rinsing fluid and residue to reduce the risk of oral infection in intubated patients. However, the angle between the water inlet and suction ends is fixed and cannot be adjusted according to the patient's actual mouth opening width. For some patients with oral diseases (such as those with limited mouth opening) or children, the fixed angle of the water inlet and suction ends makes effective insertion difficult due to their smaller mouth opening width, leading to operational difficulties and potentially causing tearing of the corners of the mouth due to forced insertion of the instruments, affecting the safety and universality of clinical use. Utility Model Content

[0003] The purpose of this invention is to provide an adjustable-angle oral irrigation and suction device to solve the aforementioned problems in the prior art.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0005] An adjustable-angle oral irrigation and suction device includes a water inlet plate, a liquid suction plate, and a central column. The tail of the water inlet plate and the tail of the liquid suction plate are respectively provided with a first connecting plate and a second connecting plate. The first connecting plate is coaxially rotatably connected to the second connecting plate through the central column. A clamping module is provided outside the central column.

[0006] The beneficial effects of this invention are as follows: When the patient's mouth opening width is small, pressing the first and second connecting pieces near the water inlet and suction pieces causes them to rotate around the central column, reducing the angle between the water inlet and suction pieces, allowing the device to be inserted into the patient's mouth with a small mouth opening width. This enables the device to adapt to different patients' mouth opening widths, making it particularly suitable for patients with small mouth opening widths. It effectively solves the problem of insufficient device compatibility in existing technologies, significantly improving the ease of operation and patient safety.

[0007] Based on the above technical solution, the present invention can be further improved as follows.

[0008] Furthermore, it also includes a torsion spring, with a torsion spring sleeved on the central column, and both ends of the torsion spring being fixedly connected to the ends of the first connecting piece and the second connecting piece near the water inlet piece and the liquid absorption piece, respectively.

[0009] The further beneficial effects of adopting the above are: the torsion spring facilitates the reset of the first and second connecting pieces, enabling the water inlet piece and the suction piece to open autonomously after entering the patient's oral cavity, and to achieve rinsing and collection of rinsing fluid and residue on both sides of the patient's gums; the water inlet piece and the suction piece achieve angular stability under the reset force of the torsion spring and the limitation of the muscles on both sides of the patient's oral cavity.

[0010] Furthermore, the outer end of the central column extends beyond the first connecting piece and is threaded, with the clamping module being a nut, which is threadedly connected to the outer end of the central column.

[0011] The further beneficial effects of adopting the above are: tightening the nut can clamp the first connecting piece and the second connecting piece on the central column, thereby fixing the angle between the water inlet piece and the liquid suction piece; the limiting effect is good and the nut adjustment is simple.

[0018] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0019] Example 1

[0020] like Figures 1 to 4As shown, an adjustable-angle oral irrigation and suction device includes a water inlet plate 1, a liquid suction plate 2, and a central column 3. The tail of the water inlet plate 1 and the tail of the liquid suction plate 2 are respectively provided with a first connecting plate 11 and a second connecting plate 21. The first connecting plate 11 is coaxially rotatably connected to the second connecting plate 21 through the central column 3. A clamping module is provided outside the central column 3.

[0021] When the patient's mouth opening angle is wide enough, press the first connecting piece 11 and the second connecting piece 21 at the end near the water inlet piece 1 and the suction piece 2, causing the first connecting piece 11 and the second connecting piece 21 to rotate around the central column 3. The included angle between the water inlet piece 1 and the suction piece 2 decreases, allowing it to be placed into the mouth of a patient with a small mouth opening. This allows the device to adapt to different patients' mouth opening widths, making it especially suitable for patients with a small mouth opening width. It effectively solves the problem of insufficient device compatibility in existing technologies and significantly improves the convenience of operation and patient safety.

[0022] Example 2

[0023] like Figure 2 As shown, this embodiment is a further improvement on embodiment 1, as detailed below:

[0024] It also includes a torsion spring 31, which is sleeved on the central post 3. Both ends of the torsion spring 31 are fixedly connected to the first connecting piece 11 and the second connecting piece 21, respectively, near the end of the water inlet piece 1 and the suction piece 2. The torsion spring 31 facilitates the repositioning of the first connecting piece 11 and the second connecting piece 21, allowing the water inlet piece 1 and the suction piece 2 to open automatically after entering the patient's oral cavity, enabling rinsing and collection of rinsing fluid and residue on both sides of the patient's gums. The angle of the water inlet piece 1 and the suction piece 2 is stabilized by the repositioning force of the torsion spring 31 and the limiting force of the muscles on both sides of the patient's oral cavity. In practice, to ensure patient comfort, the elasticity of the torsion spring 31 should not be too large.

[0025] The outer end of the central column 3 extends beyond the first connecting piece 11 and is threaded. The clamping module is a nut 32, which is threaded onto the outer end of the central column 3. Rotating the nut 32 can clamp the first connecting piece 11 and the second connecting piece 21 onto the central column 3, thereby fixing the angle between the water inlet piece 1 and the liquid suction piece 2. The limiting effect is good, and the nut 32 is easy to adjust.

[0026] Example 3

[0027] like Figure 1 As shown, this embodiment is a further improvement on any one of embodiments 1 to 3, as detailed below:

[0028] Nut 32 is equipped with anti-slip teeth. This increases the friction with the fingers of medical staff and prevents slippage when rotating nut 32.

[0029] The water inlet plate 1 and the liquid suction plate 2 are connected to an external syringe and an external suction machine via the water inlet pipe 12 and the liquid suction pipe 22, respectively. The external syringe provides the flushing fluid, and the external suction machine provides the suction pressure, which is simple and efficient.

[0030] Example 5

[0031] like Figure 1 As shown, this embodiment is a further improvement on any one of embodiments 1 to 3, as detailed below:

[0032] Both the water inlet plate 1 and the liquid absorption plate 2 are made of medical-grade silicone. Medical-grade silicone is non-toxic, odorless, and has good biocompatibility.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
