Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a cerebrospinal fluid otorrhea drainage device. Background Art

[0002] Cerebrospinal fluid otorrhea is mainly seen in craniocerebral injuries and skull base fractures caused by traffic injuries, falls from heights and blows, which can cause complications such as intracranial infection (such as meningitis, ventriculitis, brain abscess), subdural hematoma, tension pneumocephalus, etc. In severe cases, it will endanger the patient's life and lead to death. The most common clinical manifestation of cerebrospinal fluid otorrhea is the outflow of clear intracranial fluid, namely cerebrospinal fluid, through the ears. The patient has a feeling of ear distension, which may be accompanied by hearing loss, pulsatile tinnitus and vertigo.

[0003] When a patient has cerebrospinal fluid otorrhea, it is necessary to ensure effective drainage of the cerebrospinal fluid. The external auditory canal should not be blocked or flushed. At present, the patient is generally placed in the affected side lying position to allow the cerebrospinal fluid to flow out naturally until it heals naturally. Sterile cotton balls are often placed at the opening of the patient's external auditory canal to attract the cerebrospinal fluid from the ear leakage to prevent the cerebrospinal fluid from flowing back into the skull and causing secondary intracranial infection. However, this cotton ball suction method has the following problems: (1) To prevent the cerebrospinal fluid from flowing back and causing retrograde intracranial infection, the cotton ball can only be placed at the opening of the external auditory canal and cannot be placed deep inside. It is easy to fall off with changes in body position and head and facial movements (talking, eating, coughing, etc.); (2) It blocks the external auditory canal, affects hearing, and is uncomfortable; (3) It is impossible to accurately measure the drainage volume and observe its properties and color to guide treatment; (4) When the volume is large, it needs to be replaced frequently, which increases the workload and affects sleep at night. Therefore, there is an urgent need for a cerebrospinal fluid otorrhea drainage device that can continuously and effectively drain the cerebrospinal fluid from the ear leakage, does not affect hearing, is easy to use, has high comfort, and is easy to carry.

[0023] The utility model is described in detail below in conjunction with the accompanying drawings.

[0024] As attached Figure 1 To Attachment Figure 5 As shown,

[0025] Specific embodiment: A cerebrospinal fluid ear leakage drainage device comprises a drainage earplug 1, wherein the drainage earplug 1 comprises a shell 1-1, a protruding connecting tube 1-2 is provided at one end of the shell 1-1, the connecting tube 1-2 is communicated with the inside of the shell 1-1, a silicone earmuff 1-3 is fixedly sleeved on the connecting tube 1-2, the silicone earmuff 1-3 can be inserted into the patient's external auditory canal, and cerebrospinal fluid enters the inside of the shell 1-1 through the connecting tube 1-2; a drainage port 1-4 is provided at the bottom of the shell 1-1, an inclined guide wall 1-5 is provided inside the shell 1-1, the lowest point of the guide wall 1-5 is located above the drainage port 1-4, a through hole is provided at the top of the shell 1-1, a vibrating membrane 1-6 is provided above the through hole, the vibrating membrane 1-6 is adhered to the top of the shell 1-1 and completely covers the through hole, a hinged arc-shaped hanging ear ring 1-7 is provided on the outer side of the shell 1-1 away from the silicone earmuff 1-3, the drainage port 1-4 is connected to the drainage tube 2, and the drainage tube 2 is connected to the drainage bag 3. During actual use, the silicone earmuff 1-3 is inserted into the patient's external auditory canal, and the cerebrospinal fluid enters the shell 1-1 through the connecting tube 1-2, and is guided to the drainage port 1-4 through the guide wall 1-5. Since the inclined guide wall 1-5 is set, the cerebrospinal fluid can smoothly enter the drainage port when the patient changes his body position and moves his head and face. In addition, a vibration membrane 1-6 is set to ensure the sealing of the shell while allowing the patient to hear the sound more clearly. The sound waves cause the vibration membrane 1-6 to vibrate, which will cause the air inside the shell 1-1 to vibrate and transmit the sound waves to the patient's ears.

[0026] When the drainage earplug 1 is cleaned or removed and placed in the wrong direction, the vibration membrane 1-6 is easily contaminated or even damaged. For this purpose, the following structure is designed: a first annular plate 4 which is an integral structure with the shell 1-1 is provided below the through hole, and a plurality of first openings 5 ​​are provided on the first annular plate 4. The outer ring of the first annular plate 4 is rotatably connected to a second annular plate 6, and a plurality of second openings 7 corresponding to the first openings are provided on the second annular plate 6. When the first opening 5 and the second opening 7 are aligned, the internal spaces of the shell 1-1 and the first annular plate 4 are connected, and the sound waves can propagate normally. At this time, if the shell 1-1 is cleaned or inverted, the liquid inside will contact the vibration membrane 1-6 and cause contamination. When the first opening 5 and the second opening 7 are misaligned, the liquid inside will no longer be able to contact the vibration membrane 1-6. An umbrella-shaped baffle 8 is fixed at the bottom of the second annular plate 6 to prevent the splashed liquid from contaminating the vibration membrane 1-6. A plurality of guide posts 9 are fixed at the top of the second annular plate 6. The guide posts 9 are slidably connected to the arc-shaped slide groove 10 at the top of the shell 1-1. A connecting block 11 is fixed at the top of the guide post 9. A spring 12 is provided at the bottom of the connecting block 11 to be sleeved with the guide post 9. The spring 12 is arranged in a spring seat 13 above the arc-shaped slide groove 10. The elastic force of the spring 12 makes the second annular plate 6 tightly pressed against the shell 1-1 to ensure the sealing of the connection. The tops of the plurality of connecting blocks 11 are fixedly connected to the annular ring 14. By pressing the annular ring 14 and rotating it, the guide post 9 slides along the arc-shaped slide groove 10, driving the second annular plate 6 to rotate, and the originally aligned first opening 5 and second opening 7 can be rotated to a dislocated state.

[0027] The drainage tube 2 is provided with an earplug interface 15, which is connected to the drainage port 1-4 of another drainage earplug 1 through a branch tube 16. The two drainage earplugs 1 are symmetrical and are used for drainage of the left and right ears respectively. This state is suitable for patients who need bilateral drainage. Preferably, the earplug interface 15 is a cap plug structure, which is connected to the piston on the branch tube 16.

[0028] The drainage tube 2 is provided with a storage bag 17, and a stop valve 18 is provided between the storage bag 17 and the drainage bag 3. The stop valve 18 is preferably a stop ball valve. When a new drainage bag 2 needs to be replaced, the stop valve 18 is closed.

[0029] A fixing clip 19 is provided on the drainage tube 2. The fixing clip 19 can be used to clamp the drainage tube 2 on clothes for temporary fixation, so as to prevent the drainage tube 2 from affecting the movement of the patient.

[0030] The drainage tube 2 is connected to the drainage bag 3 through a one-way valve 20 connector, the one-way valve 20 connector includes a valve seat 20-1, a one-way conducting valve 20-2 and a connecting cap 20-3, the valve seat 20-1 is inserted into the end of the drainage tube 2, the one-way conducting valve 20-2 is arranged on the valve seat 20-1, the connecting cap 20-3 is sleeved behind the valve seat 20-1, and the connecting cap 20-3 is threadedly connected to the threaded interface of the drainage bag 3. The one-way valve 2 can be used to avoid reflux.

[0031] The drainage bag 3 is a three-dimensional silicone bag, which can restore its original shape after being squeezed, thereby generating negative pressure. The drainage bag 3 is provided with a pouring port 3-1 and a volume scale 3-2.
