Description

Technical Field

[0001] This utility model relates to the technical field of postoperative oral care equipment, specifically a postoperative oral care suction and rinsing device. Background Technology

[0002] Postoperative oral surgery patients often experience problems such as intraoral wound pain, limited mouth opening, and nasogastric feeding, and may even experience intraoral wound bleeding. This makes postoperative oral hygiene inconvenient, and postoperative oral irrigation is extremely important. Timely suctioning of oral secretions and keeping the mouth clean and dry can not only prevent wound infection but also promote skin flap survival and improve patient comfort. Current techniques often use suction devices to remove saliva from the patient's mouth and then use irrigating devices to rinse the mouth. Obviously, irrigation and suction are performed separately, making postoperative oral care relatively complicated. Utility Model Content

[0003] The present invention aims to at least partially solve one of the technical problems in the related art: to provide a postoperative oral care suction and rinsing device that can simultaneously suction saliva from the patient's mouth and rinse the wound.

[0004] Therefore, one objective of this utility model is to provide a postoperative oral care suction and irrigation device, which includes an inner tube and an outer tube sleeved outside the inner tube. The upper end of the outer tube is fixed and sealed to the wall of the inner tube. The outer tube and the inner tube together form an annular drainage chamber. The outer wall of the outer tube is provided with a plurality of suction holes near the upper end. Each suction hole is evenly distributed along the circumference of the outer tube and communicates with the drainage chamber. The upper end of the inner tube is provided with a liquid outlet, the lower end of the inner tube is provided with a liquid inlet, and the lower end of the outer tube is provided with a drainage outlet communicating with the drainage chamber.

[0005] Preferably, the inner tube and the outer tube are an integral structure.

[0006] Preferably, the inner tube and the outer tube are made of flexible silicone material.

[0007] Preferably, the inner tube is equipped with a valve-type one-way valve to restrict the flushing fluid in the inner tube to flow only towards the outlet.

[0008] Preferably, the inner tube has a flexible brush head at the outlet, the brush head has a central channel communicating with the outlet, and the outer wall of the brush head has several bristles.

[0009] Preferably, the brush head is detachably connected to the upper end of the inner tube.

[0010] Preferably, the brush head and the inner tube are interlocked.

[0011] The above technical solution has the following advantages or beneficial effects: First, the rinsing fluid can be pumped from the inner cavity of the inner tube to the outlet to form a jet, which rinses and cleans the patient's oral cavity. The rinsing fluid, along with the patient's saliva and other secretions, can be drawn out from the outlet through the suction hole and the drainage chamber. Second, the inner tube is equipped with a valve-type one-way valve to prevent saliva from flowing back into the inner tube. Third, the brush head at the front end of the inner tube has bristles that can be used to wipe the patient's oral cavity, and the brush head can be disassembled and replaced.

[0012] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0020] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0021] The postoperative oral care suction and rinsing device according to an embodiment of the present invention will now be described in detail with reference to the accompanying drawings.

[0022] This utility model provides a postoperative oral care suction and irrigation device, as shown in the figure, including an inner tube 1 and an outer tube 2 sleeved outside the inner tube 1. The upper end of the outer tube 2 is fixed and sealed to the wall of the inner tube 1. The outer tube 2 and the inner tube 1 together form an annular drainage chamber 3. The outer wall of the outer tube 2 is provided with a plurality of suction holes 2.1 near the upper end. Each suction hole 2.1 is evenly distributed along the circumference of the outer tube 2 and communicates with the drainage chamber 3. The upper end of the inner tube 1 is provided with a liquid outlet 1.1 and the lower end of the inner tube 1 is provided with a liquid inlet 1.2. The lower end of the outer tube 2 is provided with a drainage outlet 2.2 communicating with the drainage chamber 3.

[0023] In a preferred embodiment as described above, the inner tube 1 and the outer tube 2 are made of flexible silicone material. Furthermore, the inner tube 1 and the outer tube 2 are an integral structure.

[0024] like Figure 5 As shown, the inner tube 1 is equipped with a valve-type one-way valve 4, which restricts the flushing fluid in the inner tube 1 to flow only towards the outlet 1.1. The valve-type one-way valve 4 is a very common type of existing one-way valve. It consists of a flexible diaphragm. When the flushing fluid flows upward, the pressure of the flushing fluid can drive the diaphragm to bend and deform upward, thereby opening the inner cavity of the inner tube 1. Conversely, when the liquid enters from the inlet 1.2 and flows downward along the inner tube 1, the diaphragm can automatically close the inner cavity of the inner tube 1.

[0025] Preferably, the inner tube 1 has a flexible brush head 5 at its outlet 1.1, the brush head 5 having a central channel 5.1 communicating with the outlet 1.1, and a plurality of bristles 5.2 on its outer side wall. The bristles 5.2 are integral with the brush head.

[0026] Based on the above-mentioned preferred brush head 5, the brush head 5 is detachably connected to the upper end of the inner tube 1.

[0027] Specifically, such as Figure 3 and Figure 5 As shown, the brush head 5 is inserted into the inner tube 1. The lower end of the brush head 5 is provided with a snap-fit ​​interface, and the upper end of the inner tube 1 is provided with a snap-fit ​​fastener that matches the snap-fit ​​interface. The brush head 5 is inserted and fixed to the upper end of the inner tube 1 through the snap-fit ​​connection between the snap-fit ​​interface and the snap-fit ​​fastener.

[0028] like Figure 6As shown, the drain port 2.2 at the lower end of the outer tube 2 is designed to match the interface on an existing suction device, allowing direct connection to the suction end of the existing suction device. This suction device, also known as a negative pressure suction device, is a commonly used commercially available product in clinical practice. The lower end of the inner tube 1 penetrates the side wall of the outer tube 2 and extends outside the outer tube 2, forming a drain port 1.2 at the exposed end of the lower end of the inner tube 1. This drain port 1.2 is designed to match the outlet end of an existing irrigator, allowing direct connection to the existing irrigator. This irrigator is a commonly used commercially available product in dental clinics. Its basic working principle is to use a miniature water pump to draw irrigation fluid from the container and pump it out through the outlet end.

[0029] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.

[0030] For those skilled in the art, various changes and modifications will undoubtedly be apparent after reading the above description. Therefore, the appended claims should be considered as covering all changes and modifications that encompass the true intent and scope of this utility model. Any and all equivalent scope and content within the scope of the claims should be considered as still falling within the intent and scope of this utility model.
