Description

Technical Field

[0001] This utility model belongs to the field of body fluid drainage, specifically relating to a cerebrospinal fluid otorrhea drainage device. Background Technology

[0002] Cerebrospinal fluid (CSF) leakage is a common clinical phenomenon, mainly manifested as clear fluid discharge from the ear and nose, accompanied by a series of symptoms such as low intracranial pressure. The main causes are trauma and skull base sinus surgery. Cerebrospinal fluid otorrhea occurs when CSF leaks into the nasal cavity or nasopharynx through bone defects, typically presenting as clear fluid accumulation in the tympanic cavity or leakage through a perforated tympanic membrane or Eustachian tube. Recurrent CSF leakage can lead to chronic inflammation of the middle ear and mastoid process, hearing loss, and in severe cases, intracranial infection requiring surgical treatment. The standard treatment for CSF otorrhea is medical care, primarily involving bed rest, lateral decubitus positioning, and ear canal packing with sterile absorbent cotton.

[0003] Prolonged use of the affected side lying position may cause pressure injury to the auricle on the affected side. If sterile absorbent cotton is not changed in time, it may lead to retrograde infection of the ear canal, resulting in intracranial infection. At the same time, failure to change sterile absorbent cotton in time may cause external auditory canal infection. In addition, continuous outflow of cerebrospinal fluid may cause the ear skin to be moist, increasing the risk of pressure injury. Therefore, a new technology is needed to improve this situation.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0019] like Figures 1-4 As shown, a cerebrospinal fluid otorrhea drainage device includes a pressure relief cover 1. The pressure relief cover 1 is connected from top to bottom by an elastic part 1a and a guide plate 1b. The upper end of the elastic part 1a covers the root of the ear. The setting of the elastic part 1a ensures that when the patient lies on the affected side, the ear on the affected side is in a suspended and decompressed state. The suspended setting of the ear avoids an increase in the area of ​​moist skin on the ear, thereby reducing the risk of pressure injury to the ear caused by prolonged lying on the affected side.

[0020] In this embodiment, the guide plate 1b is arranged at an angle, which enhances its guiding effect. A groove 3 protrudes through the guide plate 1b, and the inner cavity of the outer tube 4 communicates with the inner cavity of the pressure relief shroud 1 through the groove 3. The end of the outer tube 4 is connected to the container 5. This arrangement facilitates the guidance of cerebrospinal fluid flowing on the guide plate 1b through the groove 3 to the outer tube 4, while simultaneously collecting the cerebrospinal fluid through the container 5.

[0021] In this embodiment, the inner cavity of the decompression cover 1 is provided with an inner tube 2b. When the patient is in the affected side lying position, the elastic part 1a is pressed tightly against the upper surface of the guide plate 1b due to compression. The inner tube 2b opens the guide plate 1b and the elastic part 1a, so that the cerebrospinal fluid flowing on the guide plate 1b can be guided to the outer tube 4 through the groove 3.

[0022] In this embodiment, the inner wall of one end of the inner tube 2b is connected to the outer surface of one end of the absorbent sponge 2a, and the other end of the absorbent sponge 2a protrudes from one end of the inner tube 2b. The external auditory canal is blocked by the absorbent sponge 2a, and cerebrospinal fluid is introduced into the inner tube 2b through the connection between the inner tube 2b and the absorbent sponge 2a.

[0023] In this embodiment, the other end of the inner tube 2b extends into the inner cavity of the outer tube 4 through the groove 3. Cerebrospinal fluid is introduced into the inner tube 2b through the absorbent sponge 2a. When the leakage of cerebrospinal fluid exceeds the speed at which the absorbent sponge 2a introduces cerebrospinal fluid into the inner tube 2b, the cerebrospinal fluid drips onto the guide plate 1b. Through the guiding effect of the guide plate 1b, the fluid flows to the outer tube 4 through the groove 3. The superposition of the two guiding effects ensures the dryness of the external auditory canal and avoids the risk of pressure injury to the ear.

[0024] This invention uses a pressure relief cover 1 to suspend and depress the affected ear. By combining the drainage effect of the absorbent sponge 2a and the inner tube 2b with the overall drainage effect of the guide plate 1b, groove 3, and outer tube 4, the external auditory canal is kept dry, reducing the risk of pressure injury to the ear.

[0025] In this embodiment, the upper end of the elastic part 1a is fixed to the ear root by adhesive, which makes it easy to fix the whole device to the ear root.

[0026] In this embodiment, the groove 3 is located at the lower end of the obliquely arranged guide plate 1b. The cross-section of the groove 3 is semi-circular. When the leakage of cerebrospinal fluid exceeds the speed at which the absorbent sponge 2a introduces the inner tube 2b, the cerebrospinal fluid drips onto the guide plate 1b. Since the groove 3 is located at the lower end of the obliquely arranged guide plate 1b, the cerebrospinal fluid flows towards the groove 3. The semi-circular groove 3 facilitates the concentration of the cerebrospinal fluid on the guide plate 1b to the groove 3, and then flows to the outer tube 4 through the groove 3.

[0027] In this embodiment, the inner cavity of the decompression cover 1 is connected from top to bottom by a cylindrical cavity 6a and a drainage cavity 6b. The contour of one side of the drainage cavity 6b coincides with the contour of one side of the cylindrical cavity 6a, and the contour of the other side of the drainage cavity 6b is located outside the contour of the other side of the cylindrical cavity 6a. The opening of the groove 3 is located on the other side of the drainage cavity 6b. When the patient changes position, the cerebrospinal fluid on the drainage plate 1b flows to the other side of the drainage cavity 6b, preventing the cerebrospinal fluid on the drainage plate 1b from flowing back into the ear canal.

[0028] In this embodiment, the inner tube 2b and the outer tube 4 are flexible hoses. The elastic part 1a is filled with cotton, which has a good elastic effect and serves as a pressure-reducing filler. The outer surface of the elastic part 1a is provided with a waterproof layer, which facilitates cleaning and prevents the cotton filled in the elastic part 1a from becoming damp, thus reducing the pressure-reducing effect.

[0029] The operation process in this embodiment is as follows:

[0030] S1 connection: Insert the other end of the absorbent sponge 2a into the external auditory canal, so that the absorbent sponge 2a and the external auditory canal form a pre-tight force, and place the container 5 below the plane of the ear;

[0031] S2 Fixation: The upper end of the elastic part 1a is fixed to the root of the ear by adhesive, so that the groove 3 is located below the affected ear;

[0032] S3 position: The patient lies on the affected side with the lower end of the drainage plate 1b suspended in the air. Since the drainage plate 1b is arranged at an angle, when the leakage of cerebrospinal fluid exceeds the speed at which the absorbent sponge 2a introduces the cerebrospinal fluid into the inner tube 2b, the cerebrospinal fluid flowing on the drainage plate 1b flows into the groove 3 and then through the outer tube 4 to the container 5. At the same time, the absorbent sponge 2a guides the cerebrospinal fluid to the inner tube 2b, and then through the inner tube 2b to the container 5. By combining the drainage effects of the absorbent sponge 2a and the inner tube 2b with the overall drainage effect of the drainage plate 1b, groove 3, and outer tube 4, the external auditory canal is kept dry, reducing the risk of pressure injury to the ear. Meanwhile, since the container 5 is positioned below the ear plane, the patient's cerebrospinal fluid is introduced into the container 5.
