Description

Technical Field

[0001] The present invention relates to the field of oral treatment equipment, in particular to a visual negative pressure suction probe used for visualizing and clearly suctioning foreign matter in the oral cavity. Background Art

[0002] Vacuum suction during oral treatment is a crucial procedure for removing foreign matter from the patient's mouth, reducing the risk of choking and coughing, and ensuring smooth oral treatment. During oral treatment, vacuum suction is often performed by a nurse holding a vacuum suction probe.

[0003] The principle of the suction device is very simple. It is to create a negative pressure state in the suction head through a certain method. In this way, the atmospheric pressure will squeeze the material outside the suction head into the suction head, thus achieving the "suction" effect. Negative pressure suction is a key step required for almost all oral treatments. Currently, negative pressure suction devices with visual designs are large and costly. Repeated disinfection during use not only shortens the service life but also increases the risk of cross-infection. In addition, there is generally a deviation in the design of the visual lens and the suction part, which reduces the accuracy of the doctor's operation. Utility Model Content

[0004] The purpose of this utility model is to solve the shortcomings of the existing technology and to propose a disposable probe that is used in conjunction with a visualization probe to reduce the size of the equipment while reducing medical costs and cross-infection and improving the suction accuracy of an oral chair-based visualization negative pressure suction probe.

[0005] To achieve the above-mentioned purpose, the present invention adopts the following technical solution: a visual negative pressure suction probe for an oral chair position, comprising a connecting tube, a fiber optic camera, a disposable probe and a fixing device, one end of the connecting tube being connected to a dedicated negative pressure generator, and the other end passing through the fixing device and connected to the disposable probe, the fiber optic camera being adhered to the lower surface of the connecting tube and one end of the camera passing through the fixing device.

[0006] Preferably, the disposable probe is made of a hard transparent material and includes a horizontal end, a suction end and an anti-backflow baffle. The horizontal end is inserted into the connecting tube, and the suction end is offset downward so that the center of the port is flush with the fiber optic camera to facilitate accurate positioning of the suction position. The anti-backflow baffle is arranged on the inner wall of the disposable probe.

[0007] Preferably, the fixing device includes two through holes for fixing the connecting tube and the optical fiber camera within a certain range so that they will not be displaced during use.

[0008] Preferably, the connecting tube is made of PVC and connects the disposable probe and the professional negative pressure generator.

[0009] Preferably, the optical fiber camera includes a lens portion and a channel portion, the lens portion passes through the fixing device, and the channel portion is adhered to the lower surface of the connecting tube.

[0010] Compared with the existing technology, the beneficial effects of the present invention are as follows: (1) The use of a replaceable disposable probe at the front end of the probe reduces medical costs and the risk of cross-infection; (2) The probe is equipped with a fiber optic camera to determine the suction position, which improves the accuracy of the suction work. The suction end of the disposable probe is moved down to be flush with the camera, which can more accurately determine the suction position. (3) The overall structure of the probe is simple and compact, which is more convenient to use. The overall cost is low and reduces the financial burden on patients. (4) The combination of the disposable probe and the connecting tube connection design and the fixing device makes the entire probe more secure during use and reduces problems such as displacement or falling off.

[0014] In order to provide a further understanding of the purpose, structure, features, and functions of the present invention, the following detailed description is provided in conjunction with the embodiments. Figure 1 As shown, an oral chair position visualization negative pressure suction probe includes a connecting tube 1, a fiber optic camera 2, a disposable probe 3 and a fixing device 4. One end of the connecting tube 1 is connected to a dedicated negative pressure generator, and the other end passes through the fixing device 4 and is connected to the disposable probe 3. The fiber optic camera 2 is adhered to the lower surface of the connecting tube 1 and the camera end passes through the fixing device 4.

[0015] like Figure 2As shown, the disposable probe 3 includes a horizontal end 301, a suction end 302 and an anti-backflow baffle 303. The horizontal end 301 is inserted into the interior of the connecting tube 1. The suction end 302 is offset downward so that the center of the port is flush with the fiber optic camera 2. Therefore, the part photographed by the fiber optic camera 2 is the suction part, which makes it convenient for the doctor to accurately determine the suction position during operation. The anti-backflow baffle 303 is provided on the inner wall of the disposable probe 3 to avoid the backflow of adsorbents during operation and to avoid secondary infection of the suction position. The fiber optic camera 2 includes a lens part 201 and a channel part 202. The lens part 201 passes through the fixing device 4, and the channel part 202 is adhered to the lower surface of the connecting tube 1 and cooperates with the fixing device 4 to make the entire probe more secure when used, reducing problems such as displacement or falling off.

[0016] like Figure 3 As shown, the fixing device 4 includes a hole 401 and a hole 402 , the hole 401 is used to fix the connecting tube 1 , and the hole 402 is used to fix the optical fiber camera 2 .

[0017] During use: align the lens part 201 of the fiber optic camera 2 with one port of the connecting tube 1, and then adhere its channel part 202 to the lower surface of the connecting tube 1. Then, align the fixed fiber optic camera 2 and the connecting tube 1 with the hole 402 and the hole 401 of the fixing device 4 respectively, and then pass through the fixing device 4 to align the hole with the lens part 201. Take out the disposable probe 3 and insert the horizontal end 301 into the connecting tube 1 in the fixing device 4. Then, connect the movable port of the connecting tube 1 to the dedicated negative pressure generator, turn on the display connected to the fiber optic camera 2 to confirm that the suction end 302 flush with the lens is in the suction position. Finally, start the negative pressure generator to operate on the objects that need to be adsorbed.

[0018] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
