Description

Ear suction tube

Technical Field

The utility model relates to a medical instrument field for otolaryngology branch of academic or vocational study especially relates to an ear attracts pipe.

Background

Cross infection of the ear canal results in the formation of a scab or crust with fungi at the inner ear canal segment and on the surface of the tympanic membrane. Due to the special position and structure and the sensitive and delicate characteristics of the ear canal wall, the damage of the ear canal wall caused by the traditional ear suction tube design in the examination, operation and treatment can cause pain and trouble for patients.

The conventional ear suction tube is flat in whole, for example, ZL201821428487.3 discloses a multifunctional suction head for ear, nose, throat, head and neck surgery, which is actually a flat ear suction tube. Some ear suction tubes are curved, and the curved portion is close to the middle portion, which has the effect of facilitating the operation, for example, the ear suction tubes disclosed in ZL201620398438.4 and ZL 201220097726.8. The portion of the ear suction tube that enters the ear canal is still straight.

Human ear canal structure is shown in fig. 1, and a section (namely d department) that external auditory canal is close to the tympanic membrane is recessed, and straight ear suction tube is difficult for attracting the material of external auditory canal low department and tympanic membrane lower part surface, often need oppress the ear canal wall hard and make the ear canal warp just can inhale, and this often makes this department ear canal wall congestion, red swelling or even hemorrhage for patient is comparatively painful. For pediatric patients, it is more difficult to attract substances at the bottom wall of the external auditory canal and on the lower surface of the tympanic membrane due to the smaller ear canal.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is: an ear suction tube capable of facilitating suction of a substance on the lower part of the external auditory canal and the lower part of the tympanic membrane is provided.

The technical scheme adopted for solving the problems is as follows: the ear suction tube comprises a suction tube main body, the front end of the suction tube main body is bent downwards to form a suction tube bending section, the bending angle of the suction tube bending section is a, a is more than or equal to 25 degrees and less than or equal to 35 degrees, the length of the suction tube bending section is b, and b is more than or equal to 4mm and less than or equal to 6 mm.

Further, the method comprises the following steps: the front end of the bent section of the suction tube is provided with a flexible end head.

Further, the method comprises the following steps: the included angle between the end surface of the bent section of the suction tube and the axis of the bent section of the suction tube is c, and c is 40 degrees.

Further, the method comprises the following steps: the flexible end is made of silica gel.

Further, the method comprises the following steps: a is 30 degrees and b is 5 mm.

The utility model has the advantages that: the utility model discloses match more with human duct shape. When in use, as shown in fig. 5, the bent section of the suction tube can easily enter the lower concave part of the external auditory canal near the tympanic membrane to suck the substances at the position, which is beneficial to ensuring the suction effect of the auditory canal; and the ear canal does not need to be deformed by pressing the ear canal wall, so that the pain of the patient can be greatly relieved.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and the following detailed description.

As shown in fig. 2 to 4, the ear suction tube includes a suction tube main body 1, and a front end of the suction tube main body 1 is bent downward to form a suction tube bent section 11.

The utility model discloses match more with human duct 2 shapes. When in use, as shown in fig. 5, the bent section 11 of the suction tube can easily enter the lower concave part of the auditory canal 2 close to the tympanic membrane 3 to suck the substances at the position, which is beneficial to ensuring the suction effect of the auditory canal 2; and the ear canal 2 does not need to be deformed by pressing the ear canal wall, thereby greatly relieving the pain of the patient.

As for the specific parameters of the suction tube bent section 11, the inventor finds out according to a large number of medical practices that the specific parameters of the suction tube bent section 11 are preferably: the bending angle of the suction tube bending section 11 is a, a is more than or equal to 25 degrees and less than or equal to 35 degrees, the length of the suction tube bending section 11 is b, and b is more than or equal to 4mm and less than or equal to 6 mm. Particularly preferably, a is 30 ° and b is 5 mm.

Adult's 2 diameters in the duct are 5 ~ 8mm usually, and 2 diameters in the duct of juveniles are 4 ~ 6mm usually, the utility model discloses attract 1 front end of pipe main part to attract pipe height to increase for current ear, nevertheless attract pipe main part 1 diameter to get when the maximum value is got for conventional diameter a and b simultaneously, attract the height of 1 front end of pipe main part still to be less than adult's 2 diameters in the duct, consequently attract pipe main part 1 can get into duct 2 smoothly. For minor adults, b may take a smaller value.

The lower end of the bent section 11 of the suction tube is relatively sharp, and in order to prevent the lower end of the bent section 11 of the suction tube from damaging the auditory canal 2 when the main body 1 of the suction tube enters the auditory canal 2, the front end of the bent section 11 of the suction tube is preferably provided with a flexible tip 111. So that the patient does not feel any significant discomfort even if the lower end of the curved section 11 of the suction tube hits the auditory canal 2. The flexible tip 111 may be made of silicone.

The end surface of the suction tube curved section 11 may be perpendicular to the axis of the suction tube curved section 11 as shown in fig. 3. When the device is used, the end surface of the bent section 11 of the suction tube is inclined downwards, so that the device is favorable for sucking substances positioned in the lower concave part of the auditory canal 2; however, the end surface of the curved section 11 of the suction tube is difficult to move forward, which is not favorable for sucking the substances adhered to the surface of the tympanic membrane 3.

The angle between the end surface of the suction tube bending section 11 and the axis of the suction tube bending section 11 is preferably c, and c is 40 degrees. When the ear canal suction device is used, the end face of the bent section 11 of the suction tube can face forwards, so that substances adhered to the surface of the tympanic membrane 3 can be sucked, and meanwhile, the ear canal suction device has a good suction effect on substances in the lower recess of the ear canal 2.
