Technical Field

[0001] The invention relates to the technical field of slit lamp microscopes, and in particular to a slit lamp microscope inspection instrument that is easy to use. Background Art

[0002] The slit lamp microscope is an essential instrument for ophthalmic examination. It also plays a key role in the detection of diabetic retinopathy. It consists of a lighting system and a binocular microscope. It can not only observe superficial lesions very clearly, but also adjust the focus and width of the light source to make an "optical section", thereby clearly showing lesions in deep tissues.

[0003] A slit lamp microscope is disclosed in the patent with patent publication number CN212574857U, which includes a base, a bottom frame fixedly mounted on the top of the base, a support frame and a lamp frame arranged on the top of the bottom frame, a microscope fixedly mounted on the top of the support frame, and a light source arranged on the top of the lamp frame.

[0004] However, the patent has the following problems: when in use, the patient supports the head by placing the chin on the lower support and the forehead on the forehead support, which is convenient for medical staff to perform eye examinations. However, special groups may have difficulty keeping their heads fixed during the test, including elderly patients who may suffer from muscle weakness, joint stiffness or neck discomfort; young children or uncooperative children; patients with attention deficit hyperactivity disorder (ADHD); patients with Parkinson's disease or other neurological diseases who have involuntary tremors or movements; visually impaired people or patients after ophthalmic surgery. This movement may affect the slit lamp microscope's accurate measurement of the eye position and angle, resulting in errors in the test results and affecting the accuracy of the diagnosis. Summary of the invention

[0005] In view of the problem in the prior art that special groups of people may find it difficult to keep their heads stable during examinations, and are prone to move their heads unconsciously, which affects the accurate measurement of the position and angle of the eyes by the slit lamp microscope, an easy-to-use slit lamp microscope examination instrument is proposed.

[0006] One aspect of the present application provides an easy-to-use slit lamp microscope examination instrument, the purpose of which is to add a structure to support and fix the patient's head to prevent the patient's head from moving during the inspection process, thereby ensuring that the slit lamp microscope can accurately measure the position and angle of the patient's eyes.

[0007] The technical solution of the present invention is: a slit lamp microscope inspection instrument that is easy to use, including a base plate, a fixed seat arranged on the top surface of the base plate, a sliding seat arranged on the top of the fixed seat, a detection microscope arranged on the top of the sliding seat, a slit illumination light source arranged on the top of the sliding seat, a mounting rod arranged on the side wall of the base plate, a support bracket arranged on the rod wall of the mounting rod, and a support bracket arranged on the top of the mounting rod, an arc plate is slidably installed on the top of the support bracket, a reinforcement plate for assisting in fixing the patient's head is slidably installed on the top of the support bracket, an elastic rubber pad is arranged on a side of the reinforcement plate close to the arc plate, and the elastic rubber pad is adapted to the shape of the human head; a control component for limiting the sliding speed of the reinforcement plate is arranged at the bottom of the support bracket.

[0008] Furthermore, the control component includes a U-shaped tube arranged on the bottom surface of the support bracket, a narrow section arranged in the middle of the U-shaped tube, a first piston rod arranged at one end of the U-shaped tube, a third through groove opened on the outer wall of the support bracket for sliding of the first piston rod, a first elastic member sleeved on the rod wall of the first piston rod, a second piston rod arranged at the other end of the U-shaped tube, and a lifting plate arranged at the top end of the second piston rod, and the top end of the first piston rod is fixedly connected to the bottom surface of the arc plate, one end of the first elastic member is fixedly connected to the bottom surface of the arc plate, and the other end of the first elastic member is fixedly connected to the top surface of the support bracket, and the sliding speed of the reinforcement plate is controlled by the lifting speed of the lifting plate.

[0009] Furthermore, the control component also includes a guide rod arranged on the bottom surface of the arc-shaped plate, and a second through groove opened on the outer wall of the support bracket for the guide rod to slide.

[0010] Furthermore, the control component also includes a sliding tube mounted on the outer wall of the lifting plate, a limiting tube arranged on the outer wall of the support bracket, a connecting rod arranged on the side of the reinforcement plate away from the arc plate, a first hinged rod arranged on the outer wall of the limiting tube, and a second hinged rod arranged on the outer wall of the reinforcement plate, and the connecting rod slides inside the limiting tube, one end of the first hinged rod away from the limiting tube is hinged to the outer wall of the sliding tube, and one end of the second hinged rod away from the reinforcement plate is hinged to the outer wall of the sliding tube.

[0011] Furthermore, hydraulic oil is arranged inside the U-shaped tube.

[0012] Furthermore, the control component also includes a shaft shoulder arranged on the rod wall of the second piston rod, a first through groove opened on the outer wall of the lifting plate for the second piston rod to slide, and a buffer member arranged between the lifting plate and the shaft shoulder.

[0013] Furthermore, the buffer member is a second elastic member, and one end of the second elastic member is fixedly connected to the bottom surface of the lifting plate, and the other end of the second elastic member is fixedly connected to the top surface of the shaft shoulder.

[0014] Furthermore, a shielding plate is provided on the bottom surface of the support bracket.

[0015] Furthermore, a rod wall of the mounting rod is provided with a fixing piece for fixing the position of the supporting bracket, and the fixing piece is located below the shielding plate.

[0016] Furthermore, a first padding paper is arranged on a side surface of the elastic rubber pad close to the arc-shaped plate, and a second padding paper is arranged on the top surface of the arc-shaped plate.

[0017] Beneficial effects of the present invention:

[0018] 1. The patient sits in front of the support and places his chin on the arc-shaped plate, which can drive the second elastic member and the lifting plate to rise. At this time, the second elastic member is almost not compressed. The lifting plate rises and drives the two reinforcement plates to move in relative directions until the two elastic rubber pads fit the patient's head. Thus, the device can further clamp, support and fix the patient's head to ensure that the patient's head can be firmly clamped and supported, which can effectively reduce unnecessary head movement of special groups during the test, including elderly patients, young children or uncooperative children, patients with ADHD, patients with Parkinson's disease or other neurological diseases, visually impaired people and patients after ophthalmic surgery.

[0019] 2. By controlling the U-shaped tube and the narrow section in the component, the descending speed of the arc plate and the sliding speed of the reinforcement plate can be limited, and finally the two reinforcement plates can be controlled to move slowly in relative directions, driving the two elastic rubber pads to slowly approach the patient's head, thereby effectively protecting the patient's head and preventing the two reinforcement plates from clamping the patient's head quickly and suddenly, causing damage and psychological pressure to the patient.

[0020] 3. Through the cooperation between the shaft shoulder, the second elastic part and the lifting plate, when the two elastic rubber pads are in contact with the patient's head, the arc plate is still descending and has not reached the bottom. At this time, the second piston rod and the shaft shoulder continue to rise, the lifting plate stops rising, and the second elastic part is compressed. Therefore, the device can meet the needs of patients with different head widths, ensure the comfort of patients, and prevent the two reinforcement plates from excessively clamping the patient's head and causing discomfort to the patient.

[0021] 4. The first pad paper and the second pad paper and their fixing device make it easier to clean the elastic rubber pad and the support bracket. After each use, the patient can tear off the outermost first pad paper and the second pad paper respectively, which is convenient for the next person to be tested to fix his head. At the same time, the combination of the first threaded barrel, the second threaded barrel and the T-shaped screw rod is easy to disassemble and install the first pad paper and the second pad paper, and has certain durability and stability, making it easier to maintain the first pad paper and the second pad paper, which helps to maintain long-term hygiene standards.

[0034] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0035] Example 1, reference Figure 1-Figure 6, which is the first embodiment of the present invention, provides a slit lamp microscope inspection instrument that is easy to use, including a base plate 1, a fixed seat 2 fixedly mounted on the top surface of the base plate 1, a sliding seat 3 slidably mounted on the top of the fixed seat 2, a detection microscope 4 fixedly mounted on the top of the sliding seat 3, a slit illumination light source 5 fixedly mounted on the top of the sliding seat 3, a mounting rod 6 fixedly mounted on the side wall of the base plate 1, a support bracket 7 slidably mounted on the rod wall of the mounting rod 6, and a support bracket 8 fixedly mounted on the top of the mounting rod 6, an arc plate 9 is slidably mounted on the top of the support bracket 7, a reinforcement plate 10 for assisting in fixing the patient's head is slidably mounted on the top of the support bracket 7, an elastic rubber pad 11 is fixedly mounted on a side of the reinforcement plate 10 close to the arc plate 9, and the elastic rubber pad 11 is adapted to the shape of the human head.

[0036] Specifically, the sliding seat 3 slides on the top of the fixed seat 2 by electric means, wherein the working principles of the sliding seat 3, the detection microscope 4, and the slit illumination light source 5 are all existing technologies and will not be elaborated on herein. An arc-shaped groove adapted to the arc-shaped plate 9 is provided on the top surface of the support bracket 7, two reinforcement plates 10 are provided, and the two reinforcement plates 10 are installed opposite to each other. The elastic rubber pad 11 specifically includes an internally arranged sponge pad and an externally coated rubber pad, so that the elastic rubber pad 11 can fit patients with different head shapes and sizes, thereby improving the applicability of the device.

[0037] When the patient places his chin on the arc plate 9, the arc plate 9 descends and drives the two reinforcement plates 10 to move in opposite directions until the two elastic rubber pads 11 fit the patient's head. The two reinforcement plates 10 can reinforce, support and fix the patient's head.

[0038] Reference Figure 1-Figure 8 A control component for limiting the sliding speed of the reinforcement plate 10 is provided at the bottom of the support bracket 7.

[0039] Specifically, through the control components that are set, the descending speed of the arc plate 9 and the sliding speed of the reinforcement plate 10 can be limited, and finally the two reinforcement plates 10 are controlled to move slowly in relative directions, so as to effectively protect the patient's head and prevent the two reinforcement plates 10 from clamping the patient's head quickly and suddenly, causing damage and psychological pressure to the patient.

[0040] Reference Figure 1-Figure 3 A shielding plate 12 is fixedly mounted on the bottom surface of the support bracket 7 .

[0041] Specifically, the shielding plate 12 faces the direction of the patient and can shield the parts of the control component, thereby improving the overall aesthetics of the device and alleviating the psychological pressure of the patient.

[0042] Reference Figure 1-Figure 3A fixing member 13 for fixing the position of the support bracket 7 is slidably installed on the rod wall of the mounting rod 6 , and the fixing member 13 is located below the shielding plate 12 .

[0043] Specifically, the fixing member 13 can be a fixing structure such as a clamp or a fastening bolt commonly used in the prior art, which will not be elaborated here. By setting the fixing member 13, the shielding plate 12 and the support bracket 7 can be blocked to prevent the support bracket 7 and the shielding plate 12 from continuing to descend.

[0044] Reference Figure 4-Figure 6 The control component includes a U-shaped tube 17 fixedly mounted on the bottom surface of the support bracket 7, a narrow section 18 arranged in the middle of the U-shaped tube 17, a first piston rod 15 slidably mounted at one end of the U-shaped tube 17, a third through groove 30 opened on the outer wall of the support bracket 7 for the first piston rod 15 to slide, a first elastic member 16 sleeved on the rod wall of the first piston rod 15, a second piston rod 19 slidably mounted at the other end of the U-shaped tube 17, and a lifting plate 20 arranged at the top end of the second piston rod 19, and the top end of the first piston rod 15 is fixedly connected to the bottom surface of the arc plate 9, one end of the first elastic member 16 is fixedly connected to the bottom surface of the arc plate 9, and the other end of the first elastic member 16 is fixedly connected to the top surface of the support bracket 7, the sliding speed of the reinforcement plate 10 is controlled by the lifting speed of the lifting plate 20, and hydraulic oil 27 is arranged inside the U-shaped tube 17.

[0045] Specifically, by setting the thin and narrow section 18, the pressure when the first piston rod 15 slides can be increased. The first elastic member 16 can be a compression spring or a return spring commonly used in the prior art, and a compression spring is preferably used here. By setting the first elastic member 16, the arc plate 9 can be provided with a power for returning.

[0046] When the patient's chin is placed on the arc plate 9, the arc plate 9 and the first piston rod 15 can slowly descend, and then under the push of the hydraulic oil 27, the second piston rod 19 can be slowly driven to rise upward. The lifting plate 20 is connected to the second piston rod 19, and the lifting plate 20 is driven to rise by the second piston rod 19.

[0047] Reference Figure 5 The control component also includes a guide rod 14 fixedly mounted on the bottom surface of the arc plate 9, and a second through groove 29 provided on the outer wall of the support bracket 7 for the guide rod 14 to slide.

[0048] Specifically, through the cooperation between the guide rod 14 and the second through groove 29, the sliding trajectory of the arc plate 9 can be limited to ensure that the arc plate 9 can only perform lifting and lowering movements in the vertical direction, further improving the stability of the arc plate 9 in use.

[0049] Reference Figure 6The control component also includes a sliding tube 21 sleeved on the outer wall of the lifting plate 20, a limiting tube 22 fixedly installed on the outer wall of the support bracket 7, a connecting rod 23 fixedly installed on the side of the reinforcement plate 10 away from the arc plate 9, a first hinged rod 24 rotatably installed on the outer wall of the limiting tube 22, and a second hinged rod 25 rotatably installed on the outer wall of the reinforcement plate 10, and the connecting rod 23 slides inside the limiting tube 22, one end of the first hinged rod 24 away from the limiting tube 22 is hinged to the outer wall of the sliding tube 21, and one end of the second hinged rod 25 away from the reinforcement plate 10 is hinged to the outer wall of the sliding tube 21.

[0050] Specifically, through the cooperation between the limit tube 22 and the connecting rod 23, the sliding trajectory of the reinforcement plate 10 can be limited to ensure that the reinforcement plate 10 can only slide in the horizontal direction. Through the cooperation between the sliding tube 21, the first hinge rod 24 and the second hinge rod 25, the lifting plate 20 can be guaranteed to perform lifting and lowering movements in the vertical direction. When the lifting plate 20 rises, under the action of the first hinge rod 24 and the second hinge rod 25, the two reinforcement plates 10 can be driven to move in relative directions. When the lifting plate 20 descends, it can drive the two reinforcement plates 10 away from each other.

[0051] Example 2, reference Figure 7-Figure 8 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that the control component also includes a shoulder 26 fixedly mounted on the rod wall of the second piston rod 19, a first through groove 28 opened on the outer wall of the lifting plate 20 for the second piston rod 19 to slide, and a buffer member arranged between the lifting plate 20 and the shoulder 26.

[0052] Specifically, the pressure of the patient's chin on the arc plate 9 will drive the arc plate 9 to descend, and the head widths of different patients are different. In order to prevent the two reinforcement plates 10 from getting too close to each other, resulting in excessive clamping of the patient's head and causing discomfort to the patient, the device sets an elastic connection between the lifting plate 20 and the second piston rod 19, and the second piston rod 19 can slide inside the first through groove 28.

[0053] Reference Figure 7-Figure 8 The buffer member is a second elastic member 31 , and one end of the sliding tube 21 is fixedly connected to the bottom surface of the lifting plate 20 , and the other end of the sliding tube 21 is fixedly connected to the top surface of the shaft shoulder 26 .

[0054] Specifically, the second elastic member 31 may be a buffer spring or a return spring commonly used in the prior art, and is preferably a buffer spring.

[0055] When the two elastic rubber pads 11 are not in contact with the patient's head, the second piston rod 19 rises, which can drive the second elastic member 31 and the lifting plate 20 to rise, and the second elastic member 31 is almost not compressed at this time. When the two elastic rubber pads 11 are already in contact with the patient's head, the second piston rod 19 and the shoulder 26 continue to rise, the lifting plate 20 stops rising, and the second elastic member 31 is compressed. After the examination is completed, the first elastic member 16 drives the arc plate 9 to reset, and then the second elastic member 31 drives the lifting plate 20 and the reinforcement plate 10 to reset. The rest of the structure is the same as that of Example 1.

[0056] Example 3, reference Figure 9-10 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that a first padding paper 32 is provided on a side of the elastic rubber pad 11 close to the arc plate 9, and a second padding paper 33 is provided on the top surface of the arc plate 9.

[0057] Specifically, the first pad paper 32 and the second pad paper 33 are both disposable pad papers, and during installation, there are multiple first pad papers 32 and the second pad paper 33, not just one (the outermost first pad paper 32 and the second pad paper 33 are directly torn off after the previous patient has used them, so that they can be used by the next patient), which is beneficial to improving the hygiene and safety of the use of the device. The elastic rubber pad 11 is fixedly connected to a first threaded cylinder on one side close to the arc plate 9. Two first threaded cylinders are provided and have a certain length, so that multiple first pad papers 32 can be hung on the first threaded cylinder. The outer wall of the first pad paper 32 is provided with a first through hole for the first threaded cylinder to pass through. After multiple first pad papers 32 are hung on the two first threaded cylinders, finally a T-shaped screw with a pattern (straight or cross-shaped) is screwed into the interior of the first threaded cylinder, so that the first pad paper 32 can be fixed on the elastic rubber pad 11, thereby improving the stability of the first pad paper 32 during the inspection process.

[0058] The top surface of the arc plate 9 is fixedly connected with a second threaded cylinder. Two second threaded cylinders are provided and have a certain length, so that multiple second padding papers 33 are placed on the two second threaded cylinders. The outer wall of the second padding paper 33 is provided with a second through hole for the second threaded cylinder to pass through. After placing multiple second padding papers 33 on the two second threaded cylinders, the second padding paper 33 is finally fixed on the arc plate 9 by screwing a T-shaped screw with a pattern (straight or cross-shaped) into the interior of the second threaded cylinder, thereby improving the stability of the second padding paper 33 during the inspection process.

[0059] Based on Example 1 to Example 3, the working principle of the present invention is as follows:

[0060] When it is necessary to test the patient for diabetic retinopathy, the first pad paper 32 is first installed on the elastic rubber pad 11, and the second pad paper 33 is installed on the arc plate 9. The patient sits in front of the support bracket 7, and the medical staff sits opposite the patient.

[0061] Then the patient places his chin on the second pad paper 33 on the arc plate 9. The pressure of the head causes the arc plate 9 to descend. At the same time, the narrow section 18 increases the resistance of the first piston rod 15 when it slides. The first piston rod 15 slowly descends, driving the second piston rod 19 and the second elastic member 31 and the lifting plate 20 to rise until the first pad paper 32 on the two elastic rubber pads 11 fits the patient's head, ensuring that the head is firmly supported and avoiding unnecessary movement.

[0062] When the two elastic rubber pads 11 fit the patient's head, the arc plate 9 has not reached the bottom, the second piston rod 19 and the shoulder 26 continue to rise, the lifting plate 20 stops rising, and the second elastic member 31 is compressed. After the inspection, the first elastic member 16 drives the arc plate 9 to reset, and the second elastic member 31 drives the lifting plate 20 and the reinforcement plate 10 to reset, so as to adapt to patients with different head widths, ensure comfort in use, and prevent discomfort caused by excessive clamping. After the inspection, the patient can tear off the outermost first pad paper 32 and the second pad paper 33 respectively to ensure the hygiene of the instrument.

[0063] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
