Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an automatically detachable tympanic membrane ventilation tube. Background Art

[0002] The Otolaryngology Department is a department set up at the entrance of each hospital to treat people's ear, nose and throat diseases, including the ears, nose, throat and other parts. These are some of the parts of the human body that are most prone to disease. They are also the diseases that are most likely to bother and affect people's normal work and life. If they are not treated in time, it is easy to cause various other complications.

[0003] Tympanostomy tube placement is one of the common surgeries in otolaryngology. Currently, the most commonly implanted ventilation tubes are generally "T"-shaped or "I"-shaped. This type of tube is stable and not easy to fall off. However, some secretory otitis media recovers quickly after tube placement, and tympanic membrane ventilation tubes implanted for too long are prone to re-infection of the middle ear. In this case, the patient needs to remove the tympanic membrane ventilation tube after the condition improves. For adults, it can be removed in an outpatient clinic without spending too much money. However, it is not so easy to remove the tube for children. Children cannot tolerate pain as well as adults, and they often do not cooperate when the ventilation tube is removed. At this time, family members need to forcibly fix the child or remove it under basic anesthesia. Forced removal will undoubtedly cause physical and psychological harm to the child, and basic anesthesia greatly increases the cost of patient treatment. Therefore, it is necessary to provide a tympanic membrane ventilation tube that can reduce the pain of patient treatment. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides an automatically detachable tympanic membrane ventilation tube which can reduce the pain of treatment for patients.

[0005] The utility model provides an automatically detachable tympanic membrane ventilation tube, comprising a ventilation tube body, one end of which is provided with an inclined end surface, an inner cavity of which is provided with a discharge channel, an end of which is away from the inclined end surface is provided with a first auxiliary mechanism, one end of which is provided with a second auxiliary mechanism, and both the first auxiliary mechanism and the second auxiliary mechanism are used to improve the stability of the device and facilitate fitting with the tympanic membrane.

[0006] As the utility model provides an automatically detachable tympanic membrane ventilation tube, preferably, the first auxiliary mechanism includes a first cone block, one end of the first cone block is fixedly connected to one end of the ventilation tube body, the end of the first cone block away from the ventilation tube body is fixedly connected to a connecting block, and one side of the connecting block is fixedly connected to a second cone block.

[0007] As the utility model provides an automatically detachable tympanic membrane ventilation tube, preferably, the second auxiliary mechanism includes a chuck, the inner cavity of the chuck is provided with a discharge hole, the outer side of the chuck is provided with a slot, and the inner cavity of the slot is clamped with a rubber ring.

[0008] As the utility model provides an automatically detachable tympanic membrane ventilation tube, preferably, the diameter of the discharge hole is consistent with the diameter of the discharge channel, so as to facilitate the discharge of tympanic cavity secretions as much as possible.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

DETAILED DESCRIPTION

[0014] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0015] Please refer to Figure 1 and Figure 2 ,in Figure 1 A schematic structural diagram of a preferred embodiment of the automatically detachable tympanic membrane ventilation tube provided by the utility model; Figure 2The schematic diagram of the structure of the utility model is as follows. An automatically detachable eardrum ventilation tube comprises a ventilation tube body 1, one end of which is provided with an inclined end surface 2, an inner cavity of the ventilation tube body 1 is provided with a discharge channel 3, an end of the ventilation tube body 1 away from the inclined end surface 2 is provided with a first auxiliary mechanism 4, one end of the first auxiliary mechanism 4 is provided with a second auxiliary mechanism 5, and both the first auxiliary mechanism 4 and the second auxiliary mechanism 5 are used to improve the stability of the device and facilitate the fitting with the eardrum;

[0016] The first auxiliary mechanism 4 includes a first cone block 401, one end of the first cone block 401 is fixedly connected to one end of the ventilation pipe body 1, one end of the first cone block 401 away from the ventilation pipe body 1 is fixedly connected to a connecting block 402, and one side of the connecting block 402 is fixedly connected to a second cone block 403;

[0017] The second auxiliary mechanism 5 includes a chuck 501, the inner cavity of the chuck 501 is provided with a discharge hole 502, the outer side of the chuck 501 is provided with a clamping groove 503, and the inner cavity of the clamping groove 503 is clamped with a rubber ring 504;

[0018] The diameter of the discharge hole 502 is consistent with the diameter of the discharge channel 3, so as to discharge the tympanic secretions as much as possible.

[0019] It should be noted that the entire device (except the rubber ring 504) is made of green hard plastic. The hard material can ensure that it is not easy to deform and reduce the risk of blockage. The green material is bright in color and is not easily confused with ear canal secretions such as blood and cerumen, which is convenient for doctors to identify. One end of the ventilation tube body 1 is provided with an inclined end face 2. The inclined end face 2 is an inclined circular surface, so that it can easily penetrate the tympanic membrane and enter the tympanic cavity. The inclination angle of the inclined end face 2 is 45°. Because the angle of the Eustachian tube is 45°, it is convenient to drain the secretions out of the tympanic cavity and minimize the residue. The inner cavities of the first cone block 401, the connecting block 402 and the second cone block 403 are all provided with through holes. The diameter of the through hole is the same as that of the discharge channel 3. The diameter of the exhaust passage 3 is the same as or larger than that of the exhaust passage 3 to avoid possible blockage. By setting the first cone block 401, the connecting block 402 and the second cone block 403, the ventilation tube body 1 can be tightly fixed to the tympanic membrane at this position after implantation to avoid early falling off. By setting the chuck 501, the ventilation tube body 1 can be prevented from falling into the tympanic cavity, and at the same time, it can be closely attached to the tympanic membrane so that the ventilation tube body 1 is tightly fixed to the tympanic membrane without leaving a gap between the tympanic membrane, which can not only prevent the ventilation tube body 1 from falling off early but also increase its stability. One side of the chuck 501 is fixedly connected to one end of the second cone block 403. The rubber ring 504 set at the chuck 501 can increase the friction between the chuck 504 and external objects.

[0020] The working principle of the automatically detachable tympanic membrane ventilation tube provided by the utility model is as follows:

[0021] The device is made of green hard plastic. The hard material can ensure that it is not easy to deform and reduce the risk of blockage. The green material is bright in color and is not easily confused with ear canal secretions such as blood and cerumen, which is convenient for doctors to identify. One end of the ventilation tube body 1 is provided with an inclined end surface 2. The inclined end surface 2 is an inclined circular surface, so that it can easily penetrate the tympanic membrane and enter the tympanic cavity. The inclination angle of the inclined end surface 2 is 45°. Because the angle of the Eustachian tube is 45°, it is convenient to drain the secretions out of the tympanic cavity and minimize the residue. By setting the first cone block 401, the connecting block 402 and the second cone block 403, the ventilation tube body 1 can be tightly connected to the tympanic membrane at this position after implantation. Fixation can prevent early falling off. By setting the chuck 501, the ventilation tube main body 1 can be prevented from falling into the tympanic cavity, and at the same time, it can be close to the tympanic membrane, so that the ventilation tube main body 1 is tightly fixed to the tympanic membrane without leaving a gap between the tympanic membrane, which can not only prevent the ventilation tube main body 1 from falling off early but also increase its stability. The device does not require a special implantation device, and the operation can be completed with ear grain forceps or knee-shaped forceps. The implantation is convenient, and the device does not need to be specially removed after implantation, and can fall off automatically, reducing the trauma to the patient caused by removing the tympanic membrane ventilation tube again, reducing medical expenses. The device is especially suitable for children who are not suitable for long-term tube placement, and greatly reduces the cost of tube removal.
