The causes include complications of otitis media and middle ear cholesteatoma, incision infection after ear surgery, suppurative perichondritis of the auricle, etc. In addition to conventional antibiotic treatment, surgical drainage of abscesses is also an important treatment method. The diameter, design, fixing method, and flushing method of current surgical drainage tubes are mostly designed for wound and abscess drainage in general surgery, and do not take into account the characteristics of ear diseases and periauricular anatomy. Therefore, it is necessary to design a drainage device for ear infection abscesses.

[0003] For example, CN109718399A discloses a tympanic cavity-Eustachian tube drainage device, which includes a support sheet and a drainage strip, the support sheet is connected to one end of the drainage strip, and the surfaces of the support sheet and the drainage strip have drainage grooves, and the drainage grooves include a first drainage groove and a second drainage groove. The support sheet can cover the tympanic cavity mucosa while the drainage strip can be inserted into the Eustachian tube, the first drainage groove drains the secretions in the tympanic cavity to the drainage strip, and the second drainage groove drains the secretions drained by the first drainage groove to the outside of the tympanic cavity. The tympanic cavity-Eustachian tube drainage device can prevent adhesion of the tympanic cavity and adhesion of the tube mouth of the Eustachian tube, and drain the secretions in the tympanic cavity.

[0004] However, the existing ear drainage devices are inconvenient to use, have poor placement stability, lack a good fixing mechanism, and the drainage material is easy to spread and difficult to concentrate, and it is easy to cause reflux infection, resulting in low drainage efficiency.

[0023] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0024] The inner side of the ear abscess is mostly hard tissue, such as the temporal bone, skull or maxillofacial bone, and the outer side is soft tissue such as skin, subcutaneous tissue, fat, etc. Therefore, deep abscesses are relatively shallow on the coronal plane, but deep in the sinus or irregular in shape on the sagittal plane. Deep ear abscesses are generally irregular or deep, and there may be important blood vessels and nerves in the deep, which should be avoided from damage. The end of the drainage tube should not be sharp or hard; the existence of the auricle structure provides a good attachment point for the proper fixation of the drainage tube; ear infection abscesses often require long-term drainage, such as the formation of deep sinuses after ear surgery and the formation of abscesses due to suppurative perichondritis of the auricle, which requires the drainage tube to be properly fixed; gauze pressure bandages may be required around ear infections, and gauze bandages may cause displacement of the drainage tube, and the drainage tube also needs to be relatively stably fixed in one place; and the drainage tube can continue to exist during daily activities, and the patient does not need to stay in bed for a long time; most ear abscesses are caused by Pseudomonas aeruginosa infection, which may require continuous flushing with antibiotic liquid, and the flushing can be turned off at any time when not needed. Therefore, the present invention is designed according to the characteristics, structural characteristics and treatment needs of ear diseases.

[0025] like Figure 1 As shown, the utility model provides an integrated drainage and flushing device for otolaryngology, which can be used for drainage of infected abscesses in the outer ear and the neck around the ear. Specifically, it includes a fixing mechanism 1, a drainage tube 2, a flushing tube 3 and a downpipe 4; the fixing mechanism 1 is a hollow arc structure, and the arc structure includes a first cavity 5, a second cavity 6 and a third cavity 7, the first cavity 5 is connected to a flushing port 8 on the outside, the second cavity 6 is detachably connected to the drainage tube 2 on the inside, and the third cavity 7 is connected to the downpipe 4 on the outside; the flushing tube 3 extends to the outlet end of the drainage tube 2 through the flushing port 8, the drainage tube 2 is provided with a plurality of drainage holes 9, and the downpipe 4 is connected to a negative pressure device.

[0026] In the utility model, the arc-shaped fixing mechanism can be firmly fixed at the postauricular groove behind the auricle, and the drainage tube is beneficial to the healing and shrinkage of the tissues in the sinus tract and the abscess cavity and the reduction of the abscess cavity, and can attract secretions at multiple angles, the drainage is easy to concentrate, and the drainage efficiency is high; at the same time, the flushing tube can flush the pus in the abscess cavity and discharge the flushing liquid from the sewer pipe, so as not to generate backflow and cause pollution.

[0028] In one embodiment, if Figure 2 As shown, the drainage tube 2 is a hollow pipe structure that is from thick to thin and is in a flat shuttle shape. A plurality of drainage holes 9 are evenly distributed on the side wall 1-2 cm from the outlet end of the drainage tube 2. For example, 4-6 drainage holes can be distributed on one side. This tubular structure design that gradually becomes thinner and flat is very conducive to the healing and retraction of tissues in the sinus tract and abscess cavity and the reduction of the abscess cavity. The multiple holes 1-2 cm from the outlet end can attract secretions from multiple angles and avoid blockage.

[0029] In one embodiment, the flushing tube 3 can be used to inject antibiotics or other anti-inflammatory liquids or saline to flush the pus in the abscess cavity, and can also deliver drugs to the abscess cavity. The flushing tube 3 is provided with a clamping switch, which is arranged at the entrance end of the flushing tube 3, and can be a medical clamp, for example, for clamping; it is opened when continuous flushing with antibiotic liquid is required, and the flushing can be closed at any time when it is not required to prevent external pollutants from entering.

[0030] In one embodiment, a distance is left between the outlet end of the drainage tube 2 and the outlet end of the flushing tube 3 .

[0031] In one embodiment, the downpipe 4 also provides an external negative pressure suction interface, and some negative pressure suction devices such as a negative pressure device can be directly connected to the downpipe 4, so as to more effectively attract pus or secretions in the abscess cavity. The downpipe 4 is independent of the flushing pipe 3 and the drainage pipe 2, and the flushing liquid can also be discharged from the downpipe 4, so as not to cause contamination such as backflow.

[0032] In one embodiment, if Figure 2 As shown, the drainage tube 2 includes a first side wall 10 and a second side wall 11, and the angle between the plane where the first side wall 10 is located and the plane where the second side wall 11 is located is 10-30°, for example, can be 15°.

[0035] In one embodiment, the length of the arc-shaped structure is 10-14 cm, for example, 12 cm.

[0036] In the above implementation, by limiting the above parameters, the functions of fixing, drainage, flushing and draining can be better achieved, thereby improving the drainage efficiency.

[0037] In one embodiment, the fixing mechanism 1 is made of plastic or silicone, the drainage pipe 2 is made of plastic or silicone, the flushing pipe 3 is made of silicone, and the downpipe 4 is made of plastic or silicone.

[0038] In one embodiment, the position of the drainage tube is not fixed, but is detachably connected to the second cavity of the fixing mechanism, and can be changed according to actual conditions; the arc-shaped fixing mechanism is installed in the groove behind the ear, and medical tape can be used to stick it to the surrounding skin to strengthen fixation.
