Abstract
Description
Technical Field
[0001] This utility model belongs to the field of dental medical device technology, specifically relating to an oral drainage device that can perform rinsing. Background Technology
[0002] An oral drainage device is a medical device specifically designed for irrigation and drainage of infections in the oral and maxillofacial spaces. After mandibular angle reduction surgery or other oral surgeries, drainage tubes are often needed to remove exudate or blood from the incision and surrounding areas to accelerate wound healing and reduce infection. However, if medication is needed during drainage, the drainage process must be repeated, leading to product waste and increased medical costs. Furthermore, given the oral environment, a single drainage tube sometimes cannot adequately drain both jaws, resulting in poor drainage effectiveness and a high risk of infection. Therefore, there is an urgent need for an oral drainage device that can simultaneously perform irrigation. Summary of the Invention
[0003] This invention provides an oral drainage device capable of rinsing, thereby solving the problem in the prior art that it is impossible to simultaneously perform rinsing and bimaxillary drainage.
[0004] To achieve the above objectives, the specific technical solution provided by this utility model is as follows:
[0005] An oral drainage device capable of rinsing includes a drainage ball, with a negative pressure indicator and a first one-way valve sequentially connected above the drainage ball via a connecting tube; a first drainage tube is connected below the drainage ball, and an rinsing tube is connected to the first drainage tube for administration or rinsing; the first drainage tube has rinsing holes and drainage holes evenly arranged on it, which are respectively connected to the rinsing chamber and the drainage chamber, and the first drainage tube directly adopts the cross-shaped or cross-shaped hollow drainage tube in the prior art.
[0006] A first Robert clamp is installed on the connecting tube above the drainage ball to disconnect the negative pressure indicator from the drainage ball; a duckbill one-way valve is installed below the drainage ball to prevent backflow of the drainage fluid; a second Robert clamp is installed on the first drainage tube below the duckbill one-way valve to close the second Robert clamp and maintain negative pressure when medication or flushing is needed during suction.
[0007] The drainage ball is equipped with a drainage ball scale to indicate the volume of drainage fluid.
[0008] The first drainage tube is marked with a drainage tube scale, with the 0 mark starting from the top and moving towards the end of the drainage tube, which is used by doctors to determine the length and cut the tube according to the actual situation; more preferably, the first drainage tube is provided with an imaging line, so that the current insertion position of the drainage tube can be viewed by X-ray if necessary.
[0009] The flushing tube is connected to the flushing chamber of the first drainage tube, and a second one-way valve is provided above the flushing tube.
[0010] A further technical solution involves connecting a second drainage tube to the first drainage tube when bimaxillary drainage is required. In use, the two drainage tubes are located on the inner sides of the bimaxilla in the oral cavity, which can ensure the effectiveness of bimaxillary drainage and reduce the risk of infection.
[0011] A further advanced technical solution, for cases with large postoperative drainage volume, involves installing a T-connector between the negative pressure indicator and the drainage ball, and connecting a negative pressure device or collection bag through the T-connector to collect the drainage fluid, allowing for timely cleaning of the drainage fluid.
[0012] Compared with the prior art, the oral drainage device provided by this utility model is equipped with a rinsing tube, which can be used for drug administration or rinsing, realizing simultaneous drainage and rinsing; the two drainage tubes can be used for drainage of both jaws, ensuring the drainage effect; for cases with large postoperative drainage volume, a three-way connector is set between the negative pressure indicator and the drainage ball to connect a negative pressure device or collection bag, which can promptly clean the drainage fluid and reduce the risk of infection.

[0024] A first Robert clamp 3 is installed on the connecting tube 4 above the drainage ball 5 to cut off the connection between the negative pressure indicator 2 and the drainage ball 5; a duckbill one-way valve 6 is installed below the drainage ball 5 to prevent backflow of drainage fluid; a second Robert clamp 7 is installed on the first drainage tube 9 below the duckbill one-way valve 6 to close the second Robert clamp 7 to maintain negative pressure when medication or flushing is needed during suction.
[0025] The drainage ball 5 is equipped with a drainage ball scale 5-1 to indicate the volume of drainage fluid.
[0026] like Figure 3 , Figure 4 As shown, the first drainage tube 9 can be a cross-shaped or cross-shaped hollow drainage tube as used in the prior art.
[0027] More preferably, the first drainage tube 9 is provided with imaging lines 9-6, so that the current insertion position of the drainage tube can be viewed by X-ray if necessary.
[0028] The flushing pipe 8 is connected to the flushing chamber 9-4 of the first drainage pipe 9, and a second one-way valve 8-1 is provided above the flushing pipe 8.
[0029] like Figure 2 As shown, the first drainage tube 9 is marked with a drainage tube scale 9-1, with the 0 mark starting from the top and moving towards the end of the drainage tube, which is used by doctors to determine the length and cut the tube according to the actual situation; the first drainage tube 9 is evenly provided with irrigation holes 9-2 and drainage holes 9-3, which are connected to the irrigation chamber 9-4 and the drainage chamber 9-5 respectively.
[0030] When using this procedure, first close the second Robert clamp 7. Use a syringe to draw gas from the negative pressure indicator 2 and the drainage ball 5 through the first one-way valve 1. At this time, the negative pressure indicator 2 and the drainage ball 5 will be deflated. Insert the first drainage tube 9 into the inside of the patient's mouth. Fix the external tubing to the skin outside the patient's mouth with medical tape. Open the second Robert clamp 7 and perform the drainage operation.
