Description

Technical Field

[0001] The invention relates to the technical field of medical instruments, in particular to an ear canal cleaning device for otolaryngology. Background Art

[0002] Otolaryngology is a surgical discipline that diagnoses and treats the ear, nose, pharynx, larynx and related areas. The ear canal is usually divided into the external ear canal and the internal ear canal in clinical practice. The ear consists of three parts: the external ear, the middle ear and the inner ear. Since the ear cavity constantly secretes substances that protect the eardrum, over time, a certain amount of dirt will accumulate in the ear cavity. In addition, due to problems such as bacterial infection, the ear cavity will also develop some diseases. At this time, the ear canal needs to be cleaned to thoroughly clean the secretions or lesions in the ear canal, which is convenient for clinical treatment and subsequent medication; The traditional cleaning method is that the nurse draws saline solution with a medical syringe, holds the syringe in one hand and holds a cleaning cotton swab in the other hand, and cleans the ear canal while injecting saline solution into the patient's ear canal. This method is extremely inconvenient. There is currently an ear canal cleaning device dedicated to otolaryngology. When in use, the hand guard handheld device is used, and the cleaning cotton component attached is driven by mechanical rotation to move. This method is not sufficient in actual use, and the nurse is often required to clean it multiple times. At the same time, a single treatment also requires the nurse's free hand to assist in the operation, which greatly affects the patient's medical experience. Therefore, the existing ear canal cleaning device dedicated to otolaryngology is still inconvenient, and needs to be improved in terms of the convenience of operation for medical staff and the actual use experience of patients.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] For example, see Figures 1 to 7 The present invention provides an ear canal cleaning device for otolaryngology, comprising a main body 1, a shell 2 is fixedly connected to the surface of the main body 1, and a cleaning cotton component 3 is arranged on the side of the main body 1; The surface of the body 1 is detachably connected with a cleaning tank 4, the surface of the shell 2 is fixedly connected with a water guide plate 5, the surface of the water guide plate 5 is fixedly connected with two cleaning pipes 6, and the two cleaning pipes 6 are respectively located on both sides of the cleaning cotton component 3; It also includes a cleaning component, an injection component and an adjustment component. The cleaning component is arranged in the body 1, the injection component is transmission-connected with the cleaning component, and the adjustment component is arranged on the cleaning component.

[0019] In this embodiment, when it is necessary to clean the patient's ear canal, the nurse first installs the cleaning tank body 4 filled with saline on the device, and then allows the patient to sit down. The nurse holds the device in hand, so that the cleaning cotton component 3 is inserted into the patient's ear canal, and then starts the cleaning component to operate. Through the operation of the cleaning component, the cleaning cotton component 3 rotates and moves back and forth at the same time, so that the patient's ear canal is fully and fully cleaned. During the cleaning process, the injection component is driven to operate synchronously, so that the saline in the cleaning tank body 4 is intermittently discharged from the two cleaning tubes 6. In this way, the ear canal can be fully cleaned by flushing with saline and coordinating the movement of the cleaning cotton component 3. At the same time, this can avoid excessive flow of saline into the ear canal at one time, resulting in waste, and the use of saline is more reasonable; It is worth noting that when the nurse inserts the cleaning cotton assembly 3 into the patient's ear canal during the first use, the front ends of the two cleaning tubes 6 also extend into the ear canal. The position setting of the two cleaning tubes 6 can play a role in expanding and fixing the patient's ear canal, thereby ensuring the cleaning effect. It is also worth noting that due to the different infection conditions and sensitivities in the ear canals of different patients, if the patient feels uncomfortable with the movement of the cleaning cotton assembly 3 in the ear canal, the reciprocating displacement amplitude of the cleaning cotton assembly 3 can be controlled by adjusting the components to avoid causing discomfort to the patient or damage to the patient's ear canal.

[0020] When using it for the next patient, the cleaning cotton on the cleaning cotton assembly 3 is removed, replaced with a disposable new cleaning cotton, and the two cleaning tubes 6 are wiped with iodine tincture for disinfection.

[0021] The detachable connection mode of the cleaning tank body 4 is a snap-on connection.

[0022] See also Figures 3 to 7 The cleaning component includes a main shaft 7, and a motor 32 is fixedly connected to the inner wall of the main body 1. The output end of the motor 32 is fixedly connected to the end of the main shaft 7. By starting the motor 32, the main shaft 7 can be easily driven to rotate.

[0023] The shaft arm of the main shaft 7 is fixedly connected with a gear 18, the inner wall of the main body 1 is fixedly connected with a shaft body 9, the surface of the shaft body 9 is rotatably connected with a sleeve 10, the outer wall of the sleeve 10 is fixedly connected with a gear 2 11, the teeth of the gear 18 are meshed with the teeth of the gear 2 11, the outer wall of the sleeve 10 is rotatably connected with the inner wall of the main body 1, the end of the shaft body 9 is fixedly connected with a bevel gear 12, the inner wall of the sleeve 10 is fixedly connected with a rotating rod 13, the rod wall of the rotating rod 13 is rotatably connected with a bevel gear 2 14, the teeth of the bevel gear 2 14 are meshed with the teeth of the bevel gear 12, and the bevel gear 12 is meshed with the teeth of the bevel gear 12. A displacement groove 15 is provided on the surface of the gear 2 14, and a threaded rod 16 is rotatably connected to the groove wall of the displacement groove 15, and an adjusting block 17 is threadedly connected to the rod wall of the threaded rod 16, and a fixed shaft 18 is fixedly connected to the surface of the adjusting block 17. A transmission cylinder 19 is sleeved on the inner wall of the shell 2, and an annular groove 20 is provided on the inner wall of the transmission cylinder 19. The shaft arm of the fixed shaft 18 is slidably connected to the groove wall of the annular groove 20, and the transmission cylinder 19 is spline-slidably connected to the outer wall of the sleeve 10. The cleaning cotton assembly 3 is fixedly connected to the surface of the transmission cylinder 19, and a through opening for displacement of the transmission cylinder 19 is provided on the surface of the shell 2.

[0024] In this embodiment, the main shaft 7 can be rotated to drive the gear 1 8 to rotate, so that the gear 1 8 rotates, and the gear 2 11 rotates, and then the sleeve 10 is synchronously driven to rotate through the rotation of the gear 2 11. It is worth noting that the shaft 9 does not rotate on its own. The rotation of the sleeve 10 can make the rotating rod 13 revolve, and the bevel gear 2 14 can be revolved through the revolution of the rotating rod 13. Since the bevel gear 2 14 is in meshing state with the bevel gear 1 12, the bevel gear 2 14 will rotate while revolving through its cooperation with the bevel gear 1 12. The orbital and simultaneous rotation of the bevel gear 2 14 can synchronously drive the adjusting block 17 on the back thereof to move synchronously, and the movement of the adjusting block 17 can make the connected fixed shaft 18 revolve while The rotating rod 13 is used as the axis for circumferential displacement. When the fixed shaft 18 is displaced in a circle with the rotating rod 13 as the axis, since the annular groove 20 always keeps its limit, the fixed shaft 18 will push the annular groove 20 to move back and forth, that is, through the transmission of the annular groove 20, the fixed shaft 18 pushes the transmission cylinder 19 to move back and forth, that is, at this time, the position of the fixed shaft 18 will continue to change with the rotating rod 13 as a reference. Since the transmission cylinder 19 will also be driven by the sleeve 10 to rotate, in this way, the transmission cylinder 19 can be rotated and moved back and forth at the same time. By rotating the transmission cylinder 19 and moving back and forth at the same time, the cleaning cotton component 3 can be rotated and moved back and forth at the same time. By rotating the cleaning cotton component 3 and moving back and forth at the same time, the patient's ear canal can be fully cleaned. The two forms of movement are coordinated to make the cleaning process more comprehensive.

[0025] It is worth noting that the spline sliding connection between the transmission cylinder 19 and the sleeve 10 is a prior art, that is, when the transmission cylinder 19 moves itself, it does not affect the rotation transmission of the sleeve 10 to it, and the specific structure will not be repeated here.

[0026] See also Figures 2 to 4 The injection component includes an incomplete gear 21, which is fixedly connected to the wall of the sleeve 10, a connecting shaft 22 is fixedly connected to the inner wall of the body 1, an injection gear 23 is rotatably connected to the shaft arm of the connecting shaft 22, the teeth of the injection gear 23 are meshed with the teeth of the incomplete gear 21, a hinge shaft 24 is fixedly connected to the surface of the injection gear 23, a hinge shaft 25 is rotatably connected to the shaft arm of the hinge shaft 24, a displacement plate 26 is hinged to the end of the hinge rod 25, a piston cylinder 27 is fixedly connected to the inner wall of the body 1, and the displacement plate 26 is slidably connected to the inner wall of the piston cylinder 27; The inner wall of the piston cylinder 27 is fixedly connected with a liquid inlet pipe 28 and a liquid outlet pipe 29, both of which pass through the main body 1. The inner walls of the liquid inlet pipe 28 and the liquid outlet pipe 29 are provided with a one-way valve. The liquid inlet pipe 28 is connected to the cleaning tank body 4, and the end of the liquid outlet pipe 29 is fixedly connected with a shunt pipe 30, and the end of the shunt pipe 30 is fixedly connected to the water guide pan 5.

[0027] In this embodiment, during the rotation of the sleeve 10, the incomplete gear 21 is synchronously driven to rotate. Through the rotation of the incomplete gear 21, when the teeth of the incomplete gear 21 mesh with the teeth of the injection gear 23, the injection gear 23 can be driven to rotate. When the teeth of the incomplete gear 21 are disengaged from the teeth of the injection gear 23, the teeth of the injection gear 23 will slide along the arc edge of the incomplete gear 21. At this time, the injection gear 23 does not rotate. In this way, the injection gear 23 can be intermittently rotated by the continuous rotation of the incomplete gear 21, and the intermittent rotation of the injection gear 23 can synchronously make the hinge shaft 24 intermittently displaced in a circumferential manner. When the hinge shaft 24 is displaced in a circumferential manner, the displacement plate 26 is moved in the piston cylinder 27 through the transmission of the hinge rod 25. The displacement plate 26 is displaced back and forth, so that the displacement plate 26 can be displaced back and forth intermittently through the transmission of the hinge shaft 24. Through the displacement plate 26, when it is far away from the connection between the inlet pipe 28, the outlet pipe 29 and the piston cylinder 27, the one-way valve on the inlet pipe 28 is opened, and the one-way valve on the outlet pipe 29 is closed, so that the saline in the cleaning tank body 4 can be drawn into the piston cylinder 27. When the displacement plate 26 is close to the connection between the inlet pipe 28, the outlet pipe 29 and the piston cylinder 27, the one-way valve on the inlet pipe 28 is closed, and the one-way valve on the outlet pipe 29 is opened, so that the saline drawn into the piston cylinder 27 can be pushed out from the outlet pipe 29. At this time, the saline passes through the outlet pipe 29 and enters the water guide plate 5 from the shunt pipe 30, and is then discharged from the two cleaning pipes 6 on the water guide plate 5 to wash the ear canal. By discharging physiological saline intermittently from the two cleaning tubes 6, the movement of the cleaning cotton component 3 can be coordinated to intermittently and fully clean the ear canal. At the same time, since the displacement of the displacement plate 26 is intermittent, that is, the two cleaning tubes 6 do not always spray physiological saline, this can avoid excessive physiological saline flowing into the ear canal at one time and causing waste, and the use of physiological saline is more reasonable.

[0028] Embodiment 2, based on the above embodiment: See also Figures 5 to 7 The adjusting component includes an adjusting motor 31 , which is fixedly connected to the inner wall of the displacement slot 15 , and an output end of the adjusting motor 31 is fixedly connected to the end of the threaded rod 16 .

[0029] In this embodiment, due to the different infection conditions and ear canal sensitivities of different patients, if the patient feels uncomfortable with the movement of the cleaning cotton assembly 3 in the ear canal, the adjusting motor 31 can be started to rotate the threaded rod 16. The rotation of the threaded rod 16 can cause the adjustment block 17 to be displaced, so that the distance between the adjustment block 17 and the center of the bevel gear 14 can be changed. This can change the distance that the bevel gear 14 pushes the transmission cylinder 19 to move when it revolves and rotates. In this way, adjustment can be made as needed to reduce patient discomfort, make the equipment more widely applicable, and avoid causing discomfort to the patient or causing damage to the patient's ear canal.

[0030] Embodiment 3, based on the above embodiment: See also Figure 3 The main body 1 and the surface of the shell 2 are respectively fixedly connected with two fixtures 33, and the liquid outlet pipe 29 passes through the four fixtures 33 in sequence. Through the setting of the fixture 33, the liquid outlet pipe 29 will not shake during use, making the equipment more practical and will not block the field of vision of medical staff.

[0031] See also Figure 1 Anti-skid stickers 34 are provided on both sides of the body 1, and the surfaces of the two anti-skid stickers 34 are provided with anti-skid patterns. With the provision of the anti-skid stickers 34, nurses can hold the device more stably without slipping.

[0032] Also, see Figures 1 to 3 The materials of the two cleaning tubes 6 are both hard shell plastic material, and the sizes of the two cleaning tubes 6 are adapted to the size of the cleaning cotton assembly 3.

[0033] In this embodiment, by limiting the material and size of the cleaning tube 6, when the nurse inserts the cleaning cotton assembly 3 into the patient's ear canal during the first use, the front ends of the two cleaning tubes 6 are also inserted into the ear canal. The position setting of the two cleaning tubes 6 can expand and fix the patient's ear canal, thereby ensuring the cleaning effect.

[0034] Working principle: When the ear canal cleaning device for ENT department is used, when the patient's ear canal needs to be cleaned, the nurse first installs the cleaning tank 4 filled with physiological saline on the device, and then allows the patient to sit down. The nurse holds the device in hand, so that the cleaning cotton component 3 is inserted into the patient's ear canal, and then starts the motor 32 to rotate the main shaft 7, thereby rotating the gear 1 8, so that the gear 2 11 is rotated, and then the sleeve 10 is synchronously driven to rotate through the transmission of the gear 2 11. At this time, the bevel gear 12 and the bevel gear 2 14 cooperate to make the ear canal rotate. The transmission cylinder 19 rotates and moves back and forth at the same time, so that the cleaning cotton assembly 3 rotates and moves back and forth at the same time, so that the patient's ear canal is fully and comprehensively cleaned. During the cleaning process, the incomplete gear 21 cooperates with the injection gear 23 to synchronously make the saline in the cleaning tank 4 intermittently discharged from the two cleaning pipes 6, so that the flushing of the saline and the movement of the cleaning cotton assembly 3 can be coordinated to intermittently and fully clean the ear canal. At the same time, this can avoid excessive saline flowing into the ear canal at one time, resulting in waste, and the use of saline is more reasonable; During the ear canal cleaning process, due to the different infection conditions and sensitivities in the ear canals of different patients, if the patient feels uncomfortable with the movement of the cleaning cotton component 3 in the ear canal, the adjustment motor 31 can be started to control the reciprocating displacement amplitude of the cleaning cotton component 3 until an amplitude that the patient is more acceptable is found, thereby avoiding causing discomfort to the patient or causing damage to the patient's ear canal.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
