Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and more particularly, to a head fixation device for otolaryngology examinations. Background Art

[0002] Otolaryngology was formerly known as "Department of Ophthalmology, Otorhinolaryngology and Stomatology", and was officially named "Otolaryngology" after the reform of the Ministry of Health. The classification of otolaryngology diseases is mainly based on some common diseases that often occur in the ears, nose, and throat. Otolaryngology examinations must be carried out carefully because the ears, nose, and throat are all deep and small cavities, so special lighting devices and examination instruments must be used for examinations. When the examination instruments enter the patient's ears, nose, and throat, the patient often struggles due to the discomfort caused by the entry of the instruments, which is not conducive to the examination of their ears, nose, and throat. Therefore, in current hospitals, relevant head fixation devices are usually used to fix the patient's head to ensure better examination of the ears, nose, and throat.

[0003] The existing head fixation devices for otolaryngology examinations have the following disadvantages:

[0004] 1. The existing devices usually completely imprison the patient's head. During actual examinations, the patient often needs to cooperate with the doctor and move the head to a certain extent according to the doctor's instructions to facilitate the doctor's better observation of the affected area.

[0005] 2. Some existing devices cannot be flexibly adjusted according to the individual differences of patients to adapt to the physical characteristics of different patients, thus affecting comfort. Summary of the Invention

[0006] The object of the present invention is to provide a head fixation device for otolaryngology examinations, which can fix the patient's head so that it cannot move widely, and at the same time can make small movements to cooperate with the doctor's examination to facilitate better observation of the ears, nose, and throat, and can also make corresponding adjustments to adapt to the individual differences of patients.

[0007] The above technical object of the present invention is achieved through the following technical solutions: An otolaryngology examination head fixation device, comprising a base and a neck fixator. At the center of the top of the base, there is a hydraulic lifting rod 1, which is fixedly connected to a hydraulic lifting regulator 1. The top of the hydraulic lifting rod 1 is fixedly connected to a seat plate. On both sides of the back plate, there are symmetrically arranged connecting rods extending from back to front, and the connecting rods are fixedly connected to pedals. The seat plate is movably connected to the back plate. On the back of the back plate, there is a fixing plate. At the center of the fixing plate, there is a hydraulic lifting rod 2, which is fixedly connected to a hydraulic lifting regulator 2. The top of the hydraulic lifting rod 2 is fixedly connected to a connecting plate. On both sides of the connecting plate, there are symmetrically arranged fixing rods, and the fixing rods are rotatably connected to L-shaped rotating rods. One of the L-shaped rotating rods is connected to a connecting component 1, and the other L-shaped rotating rod is connected to a connecting component 2. The connecting component 1 is rotatably connected to a chin engaging device, and the two ends of the neck fixator are respectively fixedly connected to the connecting component 1 and the connecting component 2. The neck fixator is detachably connected to a backrest.

[0008] By adopting the above technical solutions, in the present invention, a large framework of the device is constituted by the base, the hydraulic lifting rod 1, the hydraulic lifting regulator 1, the seat plate, the back plate, the armrests symmetrically designed on both sides of the seat plate, and the pedals welded on the hydraulic lifting rod 1, for the patient to sit down so as to facilitate the examination. With the cooperation of the hydraulic lifting rod 1 and the hydraulic lifting regulator 1, its height can match the height of the patient. During the examination, the patient can place the feet on the pedals, increasing the comfort of the patient during the examination.

[0009] And the fixing plate arranged on the back of the back plate is mainly used to fix the hydraulic lifting rod 2, and the height of the hydraulic lifting rod 2 is controlled by the hydraulic lifting regulator 2. The telescopic movement of the hydraulic lifting rod 2 will drive the connecting plate fixedly connected thereto to move up and down, and then drive a series of structures such as the fixing rods, the L-shaped rotating rods, the connecting component 1, the connecting component 2, the chin engaging device, and the neck fixator to move up and down, so that it can cooperate with the height of the upper body of the patient to better fix the head of the patient.

[0010] In addition, since the L-shaped rotating rod is rotatably connected to the fixing rod, the L-shaped rotating rod can rotate a certain angle relative to the fixing rod, so as to further adjust the size of the neck fixator. The connecting component 1 and the connecting component 2 are used to assemble the neck fixator and the chin engaging device, and the backrest is used to support the head of the patient to a certain extent.

[0011] The above device can fix the head of the patient so that it cannot move in a large range, and at the same time can make small-scale movements in cooperation with the doctor's examination to facilitate better observation of the ear, nose and throat, and can also make corresponding adjustments to adapt to the individual differences of the patient.

[0012] The present invention is further configured such that: a main fixing beam and a secondary fixing beam are fixedly connected to the bottom of the seat board, a bayonet is provided on the main fixing beam, and a moving groove is provided on the secondary fixing beam;

[0013] A fixing cross beam penetrating the back board is provided at the central position of the back board, position fixers located on both sides of the back board are symmetrically provided at both ends of the fixing cross beam, a connecting beam is sleeved on the part of the fixing cross beam between the position fixer and the back board, an adjusting frame is provided at the other end of the connecting beam, an adjusting cross beam is provided inside the adjusting frame, handles are symmetrically provided at both ends of the adjusting cross beam, and a space is provided above both the main fixing beam and the secondary fixing beam for the adjusting cross beam to move.

[0014] By adopting the above technical solution, by lifting the handle and moving the adjusting cross beam to different bayonet positions, the inclination adjustment of the back board can be realized, making the device more adaptable to inspections in different situations, and further making the comfort level of the patient during the inspection higher.

[0015] Since an adjusting frame is provided on the connecting beam, it is not necessary to exert too much force to lift the handle to realize the position movement of the adjusting cross beam. In addition, since no bayonet is provided on the secondary fixing beam, it will be more convenient during the movement.

[0016] The present invention is further configured such that: the first connecting component is L-shaped, and a locking structure is provided at its top end to prevent the components connected to it from falling off.

[0017] By adopting the above technical solution, the L-shaped first connecting component can better connect the L-shaped rotating rod, the neck fixer and the chin fastener, and a locking structure is provided at its top end to prevent the neck fixer and the chin fastener from falling off.

[0018] The present invention is further configured such that: the second connecting component is L-shaped, and its height is 5 - 10 cm higher than that of the first connecting component.

[0019] By adopting the above technical solution, the L-shaped second connecting component can better connect the L-shaped rotating rod and the neck fixer. Its height being 5 - 10 cm higher than that of the first connecting component can more conveniently wind the fixing belt so that the fixing belt can be connected to it. At the same time, since no locking structure is provided at its top end, it is more convenient to open the fixing belt from the second connecting component.

[0024] By adopting the above technical solution, the patient's head leans on the backrest. Since there is a section of elastic member in the middle of the elastic column, the elastic member will deform when being squeezed. When it is necessary to cooperate with the adjustment in a certain direction for the doctor to observe better, the patient can appropriately move his / her head to apply a certain pressure on the backrest to make it deform.

[0025] The elastic member is wrapped with a soft wrapping member on the outside, which can prevent it from directly contacting the air, extend its service life, and at the same time, if the patient has long hair, the hair will not be entangled with it, causing unnecessary time waste and discomfort to the patient.

[0026] The present invention is further configured such that: the soft wrapping member has the ability of elastic deformation.

[0027] By adopting the above technical solution, the soft wrapping member has the ability of elastic deformation so that it can cooperate with the elastic member to change when the elastic member deforms.

[0028] The present invention is further configured such that: the neck fixator includes a first adjusting arc-shaped plate, a second adjusting arc-shaped plate, and a third adjusting arc-shaped plate. The two ends of the second adjusting arc-shaped plate are respectively movably connected to the first adjusting arc-shaped plate and the second adjusting arc-shaped plate. Fixing rings are provided at the ends of the first adjusting arc-shaped plate and the third adjusting arc-shaped plate away from the second adjusting arc-shaped plate.

[0029] The present invention is further configured such that: the second adjusting arc-shaped plate is movably connected to the first adjusting arc-shaped plate through adjusting component one, the second adjusting arc-shaped plate is movably connected to the third adjusting arc-shaped plate through adjusting component two. A clamping component one is provided at the center of the first adjusting arc-shaped plate, a clamping component two is provided at the center of the second adjusting arc-shaped plate, and a clamping component three is provided at the center of the third adjusting arc-shaped plate.

[0034] Since the L-shaped rotating rod is rotatably connected to the fixed rod, the L-shaped rotating rod can rotate a certain angle relative to the fixed rod to further adjust the size of the neck fixator. The first connecting component and the second connecting component are used to assemble the neck fixator and the chin holder, and the backrest is used to support the patient's head to a certain extent.

[0035] The patient's head leans on the backrest. Since a section of elastic member is provided in the middle of the elastic column, the elastic member will deform when it is squeezed. When it is necessary to cooperate with the adjustment in a certain direction for the doctor to observe better, the patient can appropriately move his head to apply a certain pressure to the backrest to make it deform.

[0036] A soft wrapping member is wrapped outside the elastic member, which can prevent it from coming into direct contact with air, prolong its service life. At the same time, if the patient has long hair, the hair will not be entangled with it, causing unnecessary time waste and discomfort to the patient.

[0037] The distance between the first adjustable arc plate, the second adjustable arc plate and the third adjustable arc plate is adjusted by adjusting the first adjusting component and the second adjusting component, so that it can better adapt to the necks of different patients.

A bayonet 305 is provided on the main fixing beam 306, and a moving groove 309 is provided on the secondary fixing beam 308; at the center position of the back plate 4, there is a fixing cross beam 301 passing through the back plate 4. At both ends of the fixing cross beam 301, position fixators 302 located on both sides of the back plate 4 are symmetrically arranged. A connecting beam 310 is sleeved on the part of the fixing cross beam 301 between the position fixator 302 and the back plate 4. At the other end of the connecting beam 310, there is an adjusting frame 303. An adjusting cross beam 307 is provided inside the adjusting frame 303. At both ends of the adjusting cross beam 307, handles 304 are symmetrically arranged. A space is provided above both the main fixing beam 306 and the secondary fixing beam 308 for the adjusting cross beam 307 to move. By lifting the handle 304 and moving the adjusting cross beam 307 to different bayonet 305 positions, the inclination angle of the back plate 4 can be adjusted, making the device more suitable for examinations in different situations, and thus making the comfort of the patient during the examination process higher. When the back plate 4 is adjusted, since the pedal 2 is fixedly connected to the back plate 4 through a connecting rod 22, it will also move with the adjustment, making it more convenient for the patient to place their feet, and its comfort is also higher.

[0050] In the above structure, the large framework of the device is composed of the base 1, the first hydraulic lifting rod 7, the first hydraulic lifting regulator 6, the seat plate 5, the back plate 4, and the armrests symmetrically designed on both sides of the seat plate 5. On both sides of the back plate 4, connecting rods 22 extending from back to front are symmetrically provided. The connecting rods 22 are fixedly connected to the pedal 2 for the patient to sit down to facilitate the examination. With the cooperation of the first hydraulic lifting rod 7 and the first hydraulic lifting regulator 6, its height can match the height of the patient. During the examination, the patient's feet can be placed on the pedal 2, increasing the comfort of the patient during the examination process.

[0051] On the back of the backboard 4, there is a fixing plate 9. At the center of the fixing plate 9, there is a second hydraulic lifting rod 10. The second hydraulic lifting rod 10 is fixedly connected to a second hydraulic lifting regulator 8. The top of the second hydraulic lifting rod 10 is fixedly connected to a connecting plate 11. On both sides of the connecting plate 11, there are symmetrically arranged fixing rods 12. The fixing rods 12 are rotatably connected to L-shaped rotating rods 13. One of the L-shaped rotating rods 13 is connected to a first connecting component 14, and the other L-shaped rotating rod 13 is connected to a second connecting component 18. The first connecting component 14 is rotatably connected to a chin fastener 20. Both ends of the neck fixator 15 are respectively fixedly connected to the first connecting component 14 and the second connecting component 18. The neck fixator 15 and the first connecting component 14 and the second connecting component 18 can be connected by welding. The neck fixator 15 is detachably connected to a backrest 17.

[0052] The fixing plate 9 arranged on the back of the backboard 4 is mainly used to fix the second hydraulic lifting rod 10. The height of the second hydraulic lifting rod 10 is controlled by the second hydraulic lifting regulator 8. The telescoping of the second hydraulic lifting rod 10 will drive the connecting plate 11 fixedly connected thereto to move up and down, and further drive a series of structures such as the fixing rods 12, L-shaped rotating rods 13, first connecting component 14, second connecting component 18, chin fastener 20, and neck fixator 15 to move up and down, so that it can cooperate with the height of the patient's upper body to better fix the patient's head.

[0053] Since the L-shaped rotating rod 13 is rotatably connected to the fixing rod 12, the L-shaped rotating rod 13 can rotate a certain angle relative to the fixing rod 12 to further adjust the size of the neck fixator 15. The first connecting component 14 and the second connecting component 18 are used to assemble the neck fixator 15 and the chin fastener 20, and the backrest 17 is used to support the patient's head to a certain extent.

[0054] The first connecting component 14 is L-shaped, and there is a locking structure at its top to prevent the components connected to it from falling off; the second connecting component 18 is L-shaped, and its height is 5 - 10 cm higher than that of the first connecting component 14.

[0055] One end of the chin fastener 20 is provided with a rotating ring 21, and the other end is provided with a fixing strap 19. The rotating ring 21 is rotatably connected to the first connecting component 14 and is placed between the locking joint at the top of the first connecting component 14 and the neck fixator 15. The distance between the neck fixator 15 and the locking mechanism can be 1 - 2 cm greater than the height of the rotating ring 21, making it easier for the rotating ring 21 to rotate. The fixing strap 19 is detachably connected to the second connecting component 18. A circle larger than the diameter of the second connecting component 18 can be tied to the head of the fixing strap 19, and it can be quickly fixed by putting it on and taking it off during daily use.

[0056] There is an elastic column 16 at the bottom of the backrest 17. The neck fixator 15 is connected to the backrest 17 through the elastic column 16, and the elastic column 16 is detachably connected to the neck fixator 15. The elastic column 16 includes an upper fixing column 1601, a lower fixing column 1603, an elastic member 1602, and a soft wrapping member 1604. The bottom of the upper fixing column 1601 is fixedly connected to the elastic member 1602, the top of the lower fixing column 1603 is fixedly connected to the elastic member 1602, the inner side wall of the upper end of the soft wrapping member 1604 is fixedly connected to the outer side wall of the lower end of the upper fixing column 1601, and the inner side wall of the lower end of the soft wrapping member 1604 is fixedly connected to the outer side wall of the upper end of the lower fixing column 1603. The soft wrapping member 1604 has the ability of elastic deformation.

[0057] The patient's head leans on the backrest 17. Since there is a section of elastic member 1602 in the middle of the elastic column 16, the elastic member 1602 will deform when being squeezed. When it is necessary to cooperate with the adjustment in a certain direction for the doctor to observe better, the patient can appropriately move his / her head to exert a certain pressure on the backrest 17 to make it deform.

[0058] The elastic member 1602 is wrapped with a soft wrapping member 1604, which can prevent it from being in direct contact with the air, extend its service life. At the same time, if the patient has long hair, the hair will not be entangled with it, causing unnecessary time waste and discomfort to the patient.

[0059] The neck fixator 15 includes a first adjustable arc plate 1503, a second adjustable arc plate 1506, and a third adjustable arc plate 1509. The two ends of the second adjustable arc plate 1506 are respectively movably connected to the first adjustable arc plate 1503 and the second adjustable arc plate 1506. Fixed rings 1501 are provided at the ends of the first adjustable arc plate 1503 and the third adjustable arc plate 1509 away from the second adjustable arc plate 1506. The second adjustable arc plate 1506 is movably connected to the first adjustable arc plate 1503 through an adjustment component one 1504, and the second adjustable arc plate 1506 is movably connected to the third adjustable arc plate 1509 through an adjustment component two 1507. A clamping component one 1502 is provided at the center of the first adjustable arc plate 1503, a clamping component two 1505 is provided at the center of the second adjustable arc plate 1506, and a clamping component three 1508 is provided at the center of the third adjustable arc plate 1509. The clamping component one 1502, the clamping component two 1505, and the clamping component three 1508 are used to connect the elastic column 16. The clamping component one 1502, the clamping component two 1505, and the clamping component three 1508 include a hole and a button for adjusting the hole. The structure is similar to the adjustment method of the height of the car seat headrest. When the button is pressed, the hole opens, and the elastic column 16 can be smoothly inserted. After no longer pressing, the fixing structure inside the hole pops out to fix the elastic column 16.

[0060] The adjustment of the spacing between the first adjustable arc plate 1503, the second adjustable arc plate 1506 and the third adjustable arc plate 1509 is achieved by adjusting component one 1504 and adjusting component two 1507, so that it can better adapt to the necks of different patients. The structures of adjusting component one 1504 and adjusting component two 1507 are similar to the adjustment method of the height of a car seat headrest. It includes a pressed button and an arc structure inserted into the first adjustable arc plate 1503, the second adjustable arc plate 1506 and the third adjustable arc plate 1509. By pressing the button, the length of the arc structure inserted into the first adjustable arc plate 1503, the second adjustable arc plate 1506 and the third adjustable arc plate 1509 can be adjusted. A locking structure is provided at the end of the arc structure to prevent it from falling off from the first adjustable arc plate, the second adjustable arc plate 1506 and the third adjustable arc plate 1509.

[0061] Connect the first engaging component 1502, the second engaging component 1505 and the third engaging component 1508 to the elastic column 16 according to requirements. For example, the second engaging component 1505 is connected to the elastic column 16. The patient can adopt a reclined posture to cooperate with the doctor's examination, while if the first engaging component 1502 or the third engaging component 1508 is connected to the elastic column 16, the patient can adopt a posture with the head tilted to the left or right side to cooperate with the doctor's examination.

[0062] Working principle: When this device is in use, the patient sits on the seat board 5. The height of the seat board 5 is adjusted by the first hydraulic lifting regulator 6, so that the device can adapt to the patient's leg length and reduce discomfort during the examination. Lean against the back board 4. The height of the neck fixator 15 is adjusted by the second hydraulic lifting regulator 8, so that it just fits the patient's shoulders and clamps the patient's neck. Then fix the fixing belt 19 to the second connecting component 18, so that the patient's chin is higher than the chin clipper 20. At this time, the movement range of the patient's head has been limited, and the only movable range is the point where the head can move relative to the neck.

[0063] According to the condition of the patient's affected area, insert the elastic column 16 connected to the backrest 17 into the corresponding position. When inserted into the first engaging component 1502, it is used to examine the patient's right ear. When inserted into the third engaging component 1508, it is used to examine the patient's left ear. When inserted into the second engaging component 1505, it is used to examine the patient's throat and nasal cavity.

[0064] This specific embodiment is only an explanation of the present invention, and it is not a limitation of the present invention. After reading this specification, those skilled in the art can make modifications to this embodiment without creative contributions according to needs, but as long as it is within the scope of the claims of the present invention, it is protected by the patent law.
