Abstract

This invention discloses a detection and protection device for corneal treatment, comprising a medical bed, a detection instrument, and a detection frame. The detection frame has two arc-shaped plates for limiting the patient's head. These arc-shaped plates are controlled by a pushing mechanism to move closer to or away from the patient's head. The arc-shaped plates have a first protective component to prevent excessive pressure on the patient's head. Below the detection instrument is a mask for protecting the patient's face. The mask is movably mounted on the detection instrument via a buffer component. Both the detection instrument and the mask are controlled by a lifting mechanism to move closer to or away from the patient's eyes. The detection instrument has a second protective component to prevent excessive pressure on the patient's face from the mask. This second protective component is triggered by the buffer component. This invention, through the first and second protective components, ensures that the arc-shaped plates and mask can limit the patient's head without causing excessive pressure, and is easy to operate.

Description

Technical Field

[0001] This invention relates to the field of ophthalmic technology, and more specifically to a detection and protection device for treating corneas. Background Technology

[0002] The cornea, the outermost transparent tissue at the front of the eyeball, is known as the "window to the eye." It directly determines whether light can enter the eye smoothly and form a clear image, while also playing a vital role in protecting the internal eye tissues. Although only 0.5-1.0 millimeters thick (thinner in the center and thicker at the periphery), it is composed of multiple intricate layers. Abnormalities in any layer can affect vision or even lead to blindness. There are many types of corneal diseases, including corneal foreign body removal (a minor outpatient procedure), corneal cross-linking (for keratoconus), laser corneal surgery, and lamellar keratoplasty. These surgeries can take anywhere from a few minutes to over two hours, making patient protection extremely important during eye treatments.

[0003] During corneal treatment, the eyes need to remain stationary for extended periods. Therefore, it is necessary to restrict the patient's head to prevent movement. However, current technology cannot fully restrict the patient's head, leading to the risk of head movement. Furthermore, there is a lack of effective protective mechanisms when restricting the patient's head, which can easily result in excessive restriction and discomfort over time. Summary of the Invention

[0004] The purpose of this invention is to provide a detection and protection device for treating corneas, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a detection and protection device for treating cornea, comprising a medical bed, a detection instrument, and a detection frame, wherein the detection frame is detachably connected to the medical bed, and the detection instrument is mounted on the detection frame;

[0006] The front of the testing frame has a vertical plate in the middle, and two arc-shaped plates on both sides of the vertical plate for limiting the patient's head. The two arc-shaped plates are inclined and symmetrical. The arc-shaped plates are controlled to move closer to or away from the patient's head by a pushing mechanism.

[0007] The arc-shaped plate is equipped with a protective component 1 to prevent the arc-shaped plate from excessively squeezing the patient's head. When the arc-shaped plate limits the patient's head, the protective component 1 operates to brake the pushing mechanism.

[0008] The detector is equipped with a face shield for protecting the patient's face. The face shield is movably mounted on the detector via a buffer assembly. Both the detector and the face shield are controlled to move closer to or away from the patient's eyes via a lifting mechanism.

[0009] The detector is equipped with a second protective component to prevent the mask from excessively compressing the patient's face. The second protective component is triggered by a buffer component.

[0010] When the mask descends and contacts the patient's head, the second protective component starts to operate, gradually slowing down the descent speed of the mask. When the mask excessively compresses the patient's head, the second protective component operates, causing the lifting mechanism to drive the detector and the mask to rise, preventing the mask from continuing to compress the patient's head downwards.

[0011] Preferably, the pushing mechanism includes a circular rack located in the middle of the outer arc surface of the arc plate, and support plates are provided on both sides of the upright plate. The two circular racks are slidably connected to the two support plates respectively. Gear 1 and Gear 2 are rotatably installed on one side of the support plate, and Gear 1 and Gear 2 are connected coaxially. Gear 1 meshes with the circular rack.

[0012] The front of the upright plate is provided with two guide posts 1. The guide posts 1 are slidably connected to push rods. Side plates are provided on both sides of the push rods. Straight racks 1 are provided on the inner side of the side plates. The two straight racks 1 are respectively meshed with two gears 2. A return spring 1 is sleeved on the guide posts 1.

[0013] When the push rod is pushed, two curved plates move closer to the patient's head and limit the movement of the two sides of the top of the head.

[0014] Preferably, the protective component includes a protective plate, the protective plate having an arc-shaped structure and being coaxial with the arc-shaped plate, the protective plate being made of an elastic material, and having a plurality of ventilation holes evenly distributed on the protective plate;

[0015] The protective plate has outer edge plates at both ends, and multiple guide posts are provided on the end face of the outer edge plates. The guide posts are slidably connected to the arc plate, and a return spring is sleeved on the outside of each guide post.

[0016] An electromagnetic block is fixedly installed on the front of the upright plate, a magnetic block is provided at the upper end of the middle part of the push rod, and a tactile switch is provided in the middle of the inner arc surface of the arc plate.

[0017] When the protective plate presses against the tactile switch, the electromagnetic block is energized and attracts the magnetic block, preventing the push rod from moving.

[0018] Preferably, the lifting mechanism includes a lifting plate, the detector is fixedly installed on the front of the lifting plate, the detection frame is provided with two guide columns three, the lifting plate is provided with guide blocks one on both sides, the guide blocks one is slidably connected to the guide columns three, and a support spring is sleeved on the guide columns three, the support spring is located at the lower end of the guide block;

[0019] A motor is fixedly installed on the detection frame. The output end of the motor is provided with a gear three. A rack two is provided on the back of the lifting plate. The gear three is meshed with the rack two.

[0020] Preferably, the buffer assembly includes two guide posts four fixed to the upper end of the mask, a limiting plate at the upper end of the guide post four, a guide block two at the bottom of the front of the detector, the guide post four and the guide block two slidingly connected, and a reset spring three sleeved on the guide post four.

[0021] Preferably, the second protective component includes a sliding rheostat located on the front of the detector, and a driving block for controlling the resistance value of the sliding rheostat is provided on one side of the limiting plate. When the mask rises, the driving block rises, which increases the resistance value of the sliding rheostat and slows down the motor speed.

[0022] The detector is also equipped with a pressure sensor on the front. When the limiting plate rises and presses against the pressure sensor, the motor reverses to make the detector and mask rise.

[0023] Preferably, the upper end of the stand plate is provided with an operating plate for supporting the doctor's elbow, and the middle of the upper end of the operating plate is provided with an operating handle for controlling the movement of the detector.

[0024] Preferably, the bottom of the mask is provided with an elastic pad for protecting the patient's forehead.

[0025] Preferably, the detachable structure is provided in two sets, which are respectively fixedly installed on both sides of the medical bed;

[0026] The detachable structure includes a base, on which two C-shaped buckles are rotatably mounted at the upper center. A fixing block is provided on the outer arc side of the buckle, and a compression spring is connected between the fixing block and the base. Two locking posts are provided on both sides of the testing frame to match the two sets of buckles. When the locking posts enter the buckle, the testing frame engages with the medical bed.

[0027] Preferably, the bottom of the testing frame is equipped with multiple sets of casters.

[0028] Compared with the prior art, the beneficial effects of the present invention are:

[0029] This invention uses a pushing mechanism and a protective component to push an arc-shaped plate and a protective plate to limit the patient's head. When the arc-shaped plate and the protective plate can limit the patient's head without causing excessive pressure, the protective plate will touch a touch switch to brake the push rod, thereby maintaining the limiting relationship between the arc-shaped plate, the protective plate and the patient's head. Therefore, it will not cause excessive pressure on the patient's head, and the doctor can directly push the push rod to operate, which is very convenient.

[0030] The lifting mechanism lowers the lifting plate and detector to examine the cornea. When the elastic pad at the bottom of the mask contacts the patient's forehead, the guide post four and the limiting plate at the top of the mask rise, causing the drive block to drive the sliding rheostat, which slows down the motor speed and gradually reduces the descent speed of the detector and mask. This reduces the pressure on the patient's forehead caused by the mask. When the detector reaches the appropriate position, the lifting mechanism stops. The return spring three ensures that the micro-elastic force of the mask in the vertical direction does not excessively compress the patient's forehead, but also limits the patient's head and ensures that the distance between the detector and the patient's eye is within reasonable parameters. If the doctor makes an operational error or the equipment malfunctions, and the mask continues to descend after limiting the patient's head, the limiting plate will touch the pressure sensor upwards, causing the motor to reverse and the detector and mask to rise and detach from the patient's face, preventing the mask from continuously pressing down on the patient's head and causing head injury.

[0031] The equipment's flexibility and mobility are improved by incorporating casters at the bottom of the testing frame and designing the testing frame as a separate unit from the medical bed. Attached Figure Description

[0043] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] Please see Figure 1-10 The present invention provides a technical solution: a detection and protection device for treating cornea, including a medical bed 1, a detector 2 and a detection frame 3. The detection frame 3 is detachably connected to the medical bed 1 by a detachable structure 4. The detector 2 is installed on the detection frame 3. The bottom of the detection frame 3 is provided with multiple sets of universal wheels 34.

[0045] The detachable structure 4 has two sets, which are fixedly installed on both sides of the medical bed 1. The detachable structure 4 includes a base 41. Two C-shaped buckles 42 are rotatably installed in the middle of the upper end of the base 41. A fixing block 43 is provided on the outer arc side of the buckle 42. A compression spring 44 is connected between the fixing block 43 and the base 41. Two locking posts 45 are provided on both sides of the detection frame 3, which match the two sets of buckles 42. When the locking posts 45 enter the buckle 42, the detection frame 3 is engaged with the medical bed 1.

[0046] When surgery is required, the patient first lies on the medical bed 1 with their head resting on the headrest. Then, the testing frame 3 is pushed to the head position on the medical bed 1, aligning the locking posts 45 on both sides of the testing frame 3 with the latches 42. Pushing the testing frame 3 causes the locking posts 45 to press against the opening of the latches 42, compressing the compression springs 44 on both sides of the latches 42. At the same time, the opening of the latches 42 opens. Continuing to push the testing frame 3 causes the locking posts 45 to engage inside the latches 42. The compression springs 44 are no longer under pressure, causing the latches 42 to return to their initial position, thus securing the testing frame 3. This prevents the testing frame 3 from easily moving during corneal treatment. The separate design of the testing frame 3 and the medical bed 1 improves the flexibility and mobility of the equipment.

[0047] The front of the testing frame 3 has a vertical plate 31 in the middle, and two arc-shaped plates 51 on both sides of the vertical plate 31 for limiting the patient's head. Both arc-shaped plates 51 are inclined and symmetrical. The arc-shaped plates 51 are controlled to move closer to or away from the patient's head by the pushing mechanism 5.

[0048] The curved plate 51 is equipped with a protective component 6 to prevent the curved plate 51 from excessively squeezing the patient's head. When the curved plate 51 limits the patient's head, the protective component 6 operates and brakes the pushing mechanism 5.

[0049] The pushing mechanism 5 includes a circular rack 52 located in the middle of the outer arc surface of the arc plate 51. The upright plate 31 has a support plate 32 on both sides. The two circular racks 52 are slidably connected to the two support plates 32 respectively. A gear 1 53 and a gear 2 54 are rotatably installed on one side of the support plate 32. The gear 1 53 and the gear 2 54 are connected coaxially. The gear 1 53 is meshed with the circular rack 52. The upright plate 31 has two guide posts 55 on the front. The guide posts 55 are slidably connected to a push rod 56. The push rod 56 has a side plate 57 on both sides. The side plate 57 has a straight rack 58 on the inner side. The two straight racks 58 are meshed with the two gears 2 54 respectively. A return spring 59 is sleeved on the guide post 55. When the push rod 56 is pushed, the two arc plates 51 move closer to the patient's head and limit the two sides of the top of the head.

[0050] The protective component 6 includes a protective plate 61, which has an arc-shaped structure and is coaxial with the arc-shaped plate 51. The protective plate 61 is made of elastic material and has several ventilation holes evenly distributed on it. The protective plate 61 has outer edge plates 62 at both ends, and multiple guide posts 63 are provided on the end face of the outer edge plates 62. The guide posts 63 are slidably connected to the arc-shaped plate 51. Each guide post 63 is fitted with a reset spring 64. An electromagnetic block 65 is fixedly installed on the front of the upright plate 31. A magnetic block 66 is provided at the upper end of the middle of the push rod 56. A tactile switch 67 is provided in the middle of the inner arc surface of the arc-shaped plate 51. When the protective plate 61 presses the tactile switch 67, the electromagnetic block 65 is energized and attracts the magnetic block 66, making the push rod 56 unable to move.

[0051] After the patient lies on the medical bed 1, the position of the patient's head needs to be adjusted so that the patient's head is in the middle of the medical bed 1. The doctor sits in front of the examination frame 3, that is, at the head position of the medical bed 1. Then the doctor pushes the push rod 56 with both hands, causing the push rod 56 to slide on the guide post 55. This causes the straight rack 58 on both sides of the push rod 56 to move, causing the gear 2 54 and gear 1 53 to rotate, causing the circular rack 52 to move, so that the arc plate 51 and the protective plate 61 are aligned with the patient's head. As the protective plate 61 approaches the patient's head, it experiences pressure, causing the guide posts 63 on the outer edges 62 of the protective plate 61 to slide on the outer edges 62 of the arc-shaped plate 51. This causes the outer arc surface of the protective plate 61 to press against the tactile switch 67 on the inner arc surface of the arc-shaped plate 51. When the tactile switch 67 is pressed, the electromagnetic block 65 is energized, generating a magnetic attraction force. This causes the magnetic block 66 on the push rod 56 to adhere to the bottom of the electromagnetic block 65, preventing the push rod 56 from moving further. At this point, both sets of... The protective plate 61 and the curved plate 51 can limit the patient's head to two positions, preventing the patient from moving horizontally. The reset spring 64 sleeved on the guide post 63 creates a buffer area between the protective plate 61 and the curved plate 51, preventing the curved plate 51 from rigidly limiting the patient's head and causing discomfort. Moreover, the protective plate 61 is made of elastic material, further ensuring the comfort of the patient's head. When the curved plate 51 and the protective plate 61 can limit the patient's head without causing excessive pressure, the protective plate 61 will touch the touch switch 67 to brake the push rod 56, thereby maintaining the limiting relationship between the curved plate 51, the protective plate 61 and the patient's head, thus preventing excessive pressure on the patient's head. The doctor can directly push the push rod 56 to operate, which is very convenient. When the corneal treatment is completed, the power to the electromagnetic block 65 is turned off, and the reset spring 59 on the guide post 55 rebounds, allowing the push rod 56, the curved plate 51 and the protective plate 61 to return to their initial positions.

[0052] Below the detector 2 is a mask 7 for protecting the patient's face. At the bottom of the mask 7 is an elastic pad 71 for protecting the patient's forehead. The mask 7 is movably mounted on the detector 2 via a buffer assembly 9. Both the detector 2 and the mask 7 are controlled by a lifting mechanism 8 to move closer to or further away from the patient's eyes.

[0053] The detector 2 is equipped with a second protective component 10 to prevent the mask 7 from excessively compressing the patient's face. The second protective component 10 is triggered to operate by the buffer component 9.

[0054] The upper end of the upright plate 31 is provided with an operating plate 33 for supporting the doctor's elbow, and the middle of the upper end of the operating plate 33 is provided with an operating handle 11 for controlling the movement of the detector 2.

[0055] When the mask 7 descends and contacts the patient's head, the second protective component 10 starts to operate, which gradually slows down the descent speed of the mask 7. When the mask 7 excessively squeezes the patient's head, the second protective component 10 operates, which causes the lifting mechanism 8 to drive the detector 2 and the mask 7 to rise, preventing the mask 7 from continuing to squeeze the patient's head downwards.

[0056] The lifting mechanism 8 includes a lifting plate 81, a detector 2 fixedly installed on the front of the lifting plate 81, two guide columns 83 on the detection frame 3, guide blocks 82 on both sides of the lifting plate 81, guide blocks 82 and guide columns 83 slidingly connected vertically, a support spring 84 is sleeved on the guide column 83, the support spring 84 is located at the lower end of the guide block 82, a motor 85 is fixedly installed on the detection frame 3, a gear 86 is provided at the output end of the motor 85, a rack 87 is provided on the back of the lifting plate 81, and the gear 86 meshes with the rack 87.

[0057] The buffer assembly 9 includes two guide posts 91 fixed to the upper end of the mask 7. A limiting plate 92 is provided at the upper end of the guide post 91. A guide block 93 is provided at the bottom of the front of the detector 2. The guide post 91 and the guide block 93 are slidably connected up and down. A reset spring 94 is sleeved on the guide post 91.

[0058] The second protective component 10 includes a sliding rheostat 101 located on the front of the detector 2. A drive block 102 is provided on one side of the limiting plate 92 to control the resistance value of the sliding rheostat 101. When the mask 7 rises, the drive block 102 rises, which increases the resistance value of the sliding rheostat 101 and slows down the speed of the motor 85.

[0059] The front of the detector 2 is also equipped with a pressure sensor 103. When the limit plate 92 rises and presses against the pressure sensor 103, the motor 85 reverses to make the detector 2 and the mask 7 rise.

[0060] In this process, after the arc-shaped plate 51 and the protective plate 61 are positioned above the patient's head by pushing mechanism 5 and protective component 6, the detector 2 can be finely adjusted by operating handle 11 so that the detector 2 corresponds vertically to the patient's eyes. Then, by using the foot pedal or button (not shown in the attached diagram), the lifting mechanism 8 can be activated, causing the lifting plate 81 and the detector 2 to descend for corneal detection. When the lifting mechanism 8 is running, motor 85 drives gear 3 86 to rotate. Through gear 3 86 and rack 2 87, the lifting plate 81 descends, causing the detector 2 and the mask 7 to descend. When the elastic pad 71 at the bottom of the mask 7 contacts the patient's forehead, the guide post 4 91 at the top of the mask 7 rises, causing the limiting plate 92 to rise. This causes the drive block 102 to drive the sliding rheostat 101, increasing the resistance of the sliding rheostat 101, decreasing the current in the circuit, and thus increasing the electrical current. As the rotation speed of motor 85 decreases, the descent of lifting plate 81 gradually slows down, thus reducing the pressure on the patient's forehead caused by mask 7. When detector 2 descends to the appropriate position, lifting mechanism 8 stops operating. Through return spring 94, the slight elasticity of mask 7 in the vertical direction not only prevents excessive pressure on the patient's forehead but also limits the patient's head position and ensures that the distance between detector 2 and the patient's eyes is within reasonable parameters. Mask 7 has cutouts to allow the patient's eyes to be exposed for treatment. If the doctor makes an operational error or the equipment malfunctions, and mask 7 continues to descend after limiting the patient's head position, limit plate 92 will touch pressure sensor 103 upwards, causing motor 85 to reverse and causing detector 2 and mask 7 to rise and detach from the patient's face, preventing mask 7 from continuously pressing down on the patient's head and causing head injury.
