Description

Technical Field

[0001] The present invention relates to the technical field of computer tomography (CT) examination bed related equipment, in particular to a bed-mounting auxiliary mechanism for a CT examination bed. Background Art

[0002] The CT examination table is an important component of the CT scanning equipment, which is used to support the patient and achieve precise positioning and movement during the scanning process.

[0003] The Chinese patent with application number CN202110508030.3 reduces manual operation with the help of a sliding lifting receiving mechanism, but its design does not take into account the particularity of the concave surface of the CT examination bed, resulting in limitations in achieving accurate and safe patient transfer. In the operation of traditional medical beds, due to height differences and concave surface adaptation issues, medical staff need to participate in the movement of patients, which leads to errors, safety risks, and excessive labor intensity. With the diversification of modern medical scenarios and the increase in efficiency (such as the need to examine patients before thrombolysis for cerebral infarction) and safety requirements, it is particularly important to design efficient, intelligent, adaptive concave and labor-saving auxiliary equipment for CT examination beds. Summary of the invention

[0004] The object of the present invention is to provide a bed-mounting auxiliary mechanism for a CT examination bed, so as to solve the problems raised in the above-mentioned background technology.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] The present invention is a bed-mounting auxiliary mechanism for a CT examination bed, comprising a frame, a lifting component, a moving component, an adjustment component and other auxiliary components;

[0007] The specific work is as follows;

[0008] A lifting component is installed on the frame, a moving component is installed on the top of the lifting component, and the moving component moves horizontally along the top of the lifting component to move the patient;

[0009] The moving assembly is provided with a conveyor belt, the running speed of which is maintained in the range of 0.1 m / s, and can carry a patient weight of up to 100 kg, for further moving the patient;

[0010] The moving assembly includes a moving frame and a rotating frame, wherein the rotating frame is rotatably connected to one end of the moving frame, and the rotating frame can achieve precise adjustment of 5° to 60° to match the concave surface requirements of the mainstream CT examination bed;

[0011] An adjustment component for adjusting the support of the rotating frame is installed at the bottom of the rotating frame.

[0012] The purpose of the above arrangement is that the lifting assembly on the rack can adjust the height of the top moving assembly thereof. When the patient needs to be moved, the moving assembly can be adjusted to a suitable height according to the height of the patient's bed and the height difference with the examination bed through the lifting assembly to prepare for the subsequent movement of the patient;

[0013] When the lifting assembly adjusts the moving assembly to a suitable height, the moving assembly moves horizontally to approach the examination bed, then moves the patient above it, and then moves horizontally toward the examination bed, thereby achieving preliminary movement of the patient;

[0014] After the moving assembly moves the patient onto it, the conveyor belt can be started to further move the patient in a smoother and more convenient manner, slowly transporting the patient to the examination bed;

[0015] When the patient needs to be moved to the examination bed, since the examination bed may have a concave surface, the rotating frame can be rotated and adjusted according to the shape of the concave surface, so that the entire moving assembly can better fit the shape of the examination bed, allowing the patient to be moved to the examination bed smoothly and accurately.

[0016] When the rotating frame rotates to adapt to the concave surface of the examination bed, the adjustment assembly can provide a stable supporting force to ensure that the rotating angle of the rotating frame is accurate and stable, thereby ensuring the safety and accuracy of the entire moving process.

[0017] Further, the lifting assembly includes a first motor, a connecting frame, a support platform and a guide rod, a plurality of the guide rods are connected to the lower surface of the support platform, and the guide rods are slidably connected to the top of the frame;

[0018] The connecting frame is connected to the lower surface of the support platform, the first motor is installed on the upper surface of the frame, the connecting frame is connected to the lower surface of the support platform, a screw is installed on the output shaft of the first motor, and the screw passes through the bottom of the connecting frame and is threaded. The first motor drive can achieve stepless adjustment of the height between 1 and 10 mm.

[0019] The purpose of the above setting is that when the first motor is started, it drives the screw to rotate, and the guide rod plays a guiding and supporting role. The support platform can move up and down stably when the screw rotates. When the screw rotates, the screw is threadedly connected to the connecting frame, and the connecting frame drives the support platform to move up and down along the guide rod, thereby realizing the lifting function.

[0020] Furthermore, teeth and grooves are respectively provided at both ends of the support platform, and the moving component cooperates with the teeth and grooves.

[0021] The purpose of the above arrangement is that the tooth grooves support and move the moving components.

[0022] Furthermore, the moving assembly also includes gears and a motor, the moving frame is slidably connected in the tooth groove, the motor is installed inside one end of the moving frame, the output shaft of the motor passes through the moving frame and is installed with a gear, and the gear is meshed with the tooth groove.

[0023] The purpose of the above arrangement is that when the motor is started, it drives the gear to rotate. Since the gear and the tooth groove are meshed with each other, the movable frame can slide in the tooth groove, thereby realizing the horizontal movement of the movable assembly along the support platform.

[0024] Furthermore, enclosure plates are respectively installed on the tops of the movable frame and the rotating frame.

[0025] The purpose of the above-mentioned setting is that when the patient is moved to the mobile rack or the rotating rack, the enclosure can block the patient to a certain extent on all sides, thereby improving the safety of the patient during the movement. Several rubber strips are arranged on the outer wall of the conveyor belt to play an anti-slip role.

[0026] Furthermore, a sliding groove is provided at the bottom of the rotating frame, and the adjustment assembly includes a cylinder, a rotating rod is rotatably connected to the output end of the cylinder, a long rod is rotatably connected to the top of the rotating rod, and sliding blocks are respectively connected to the two ends of the long rod, and the sliding blocks are slidably connected to the sliding groove.

[0027] The purpose of the above arrangement is that the adjustment component at the bottom of the rotating frame is used to adjust the posture of the rotating frame to adapt to the concave surface of the examination bed. A rotating rod is rotatably connected to the output end of the cylinder, and the top of the rotating rod is rotatably connected to a long rod. The sliding blocks at both ends of the long rod are slidably connected to the sliding groove at the bottom of the rotating frame. When the cylinder is extended or retracted, the sliding block slides in the sliding groove through the transmission of the rotating rod and the long rod, thereby driving the rotating frame to rotate relative to the mobile frame to adapt to the concave shape of the examination bed.

[0028] Furthermore, cylinders are respectively connected to the inner walls on both sides of the movable frame and the rotating frame, and the tops of the cylinders are connected to a plurality of connecting blocks, and the tops of the connecting blocks are rotatably connected to rotating wheels.

[0029] The purpose of the above arrangement is that when the patient moves in the mobile rack or the rotating rack, the rotating wheels can roll, thereby making the patient's movement smoother. At the same time, the patient's own weight squeezes the conveyor belt. During the rotation of the rotating wheels, the patient's back is massaged by the rollers, which has the effect of relieving stress and relaxing the patient.

[0030] Furthermore, rollers are rotatably connected inside the movable frame and the rotating frame respectively, a second motor is installed on the movable frame, an output shaft of the second motor is connected to one of the rollers, the conveyor belt is connected to the outer walls of the two rollers, and a plurality of rubber strips are arranged on the outer wall of the conveyor belt.

[0031] The purpose of the above setting is that the output shaft of the second motor is connected to one of the rollers, and the other roller and this roller jointly support the conveyor belt. When the second motor is started, it drives the roller connected to it to rotate. Since the conveyor belt is connected to the outer walls of the two rollers, the conveyor belt starts to run, thereby realizing auxiliary movement of the patient. Several rubber strips are arranged on the outer wall of the conveyor belt to play an anti-slip role.

[0032] Furthermore, the bottom of the frame is rotatably connected to wheels, and a friction limit assembly is installed at the bottom of the frame.

[0033] The purpose of the above arrangement is that the wheels rotatably connected to the bottom of the frame facilitate the movement of the entire bed-entering auxiliary mechanism, and the friction limit assembly is used to control the movement state of the frame.

[0034] Furthermore, the friction limit assembly includes a sliding rod, which is slidably connected to the frame, a friction plate is connected to the bottom end of the frame, a spring is arranged between the friction plate and the frame, a connecting rod is connected to the top outer wall of the sliding rod, a limiting rod is slidably connected to the outer wall of the connecting rod, a plurality of limiting holes are arranged on the outer wall of the frame, and one end of the limiting rod is inserted into the limiting hole.

[0035] The purpose of the above arrangement is that the wheels connected to the bottom of the frame are rotatably connected to facilitate the movement of the entire bed-entering auxiliary mechanism, and the friction limit assembly is used to control the movement state of the frame. The sliding rod in the friction limit assembly is slidably connected to the frame, and a spring is arranged between the friction plate and the frame. When the movement of the frame needs to be limited, the connecting rod and the limit rod at the top of the sliding rod are operated to insert one end of the limit rod into the limit hole on the outer wall of the frame, and at the same time, the sliding rod presses down the friction plate to increase the friction between the friction plate and the ground, thereby limiting the movement of the frame;

[0036] When the rack needs to be moved, the operation is reversed to reduce the friction between the friction plate and the ground, so that the wheels can rotate normally and the rack can be moved.

[0037] The present invention has the following beneficial effects:

[0038] (1) The present invention provides a moving component and an adjusting component. When the patient needs to be moved to the CT examination bed, since the CT examination bed may have a concave surface, the rotating frame can be rotated and adjusted according to the shape of the concave surface. In this way, the entire moving component can better fit the shape of the CT examination bed, so that the patient can be smoothly and accurately moved to the CT examination bed. During the process of the rotating frame rotating to adapt to the concave surface of the CT examination bed, the adjusting component can provide a stable supporting force to ensure that the rotation angle of the rotating frame is accurate and stable, thereby ensuring the safety and accuracy of the entire moving process. The problem that the prior art cannot adapt to the concave surface of the CT examination bed is completely solved, and the flexibility and versatility of the equipment are improved. It is particularly suitable for examinations of emergency departments that require rapid CT scans, bedridden patients, the elderly, and patients with limited mobility.

[0039] (2) The introduction of the conveyor belt allows patients to be moved more accurately and slowly, reducing the jerky movement or patient discomfort caused by manual operation.

[0040] (3) The present invention can reduce the labor intensity of medical staff, improve the efficiency of patient transfer operations, and reduce the average operation time by more than half.

[0041] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

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.

[0056] The present invention is a bed-mounting auxiliary mechanism for a CT examination bed, such as Figure 1 - Fig.10 As shown, it includes a frame 1, a lifting assembly 6 is installed on the frame 1, a moving assembly 7 is installed on the top of the lifting assembly 6, and the moving assembly 7 moves horizontally along the top of the lifting assembly 6 to move the patient;

[0057] A conveyor belt 5 is mounted on the moving assembly 7 for further moving the patient;

[0058] The moving assembly 7 includes a moving frame 701 and a rotating frame 702. The rotating frame 702 is rotatably connected to one end of the moving frame 701 to adapt to the concave surface of the CT examination bed;

[0059] An adjustment component 4 for supporting and adjusting the rotating frame 702 is installed at the bottom of the rotating frame 702 .

[0060] In this embodiment, the purpose of the above arrangement is that the lifting assembly 6 on the rack 1 can adjust the height of the top moving assembly 7 thereof. When the patient needs to be moved, the moving assembly 7 can be adjusted to a suitable height by the lifting assembly 6 according to the height of the patient's bed and the height difference with the CT examination bed, so as to prepare for the subsequent movement of the patient.

[0061] When the lifting assembly 6 adjusts the moving assembly 7 to a suitable height, the moving assembly 7 moves horizontally to approach the CT examination bed, then moves the patient above it, and then moves horizontally toward the CT examination bed, thereby achieving the initial movement of the patient;

[0062] After the moving assembly 7 moves the patient onto it, the conveyor belt 5 can be started to further move the patient in a smoother and more convenient manner, and slowly transport the patient to the CT examination bed;

[0063] When the patient needs to be moved to the CT examination bed, since the CT examination bed may have a concave surface, the rotating frame 702 can be rotated and adjusted according to the shape of the concave surface, so that the entire moving assembly 7 can better fit the shape of the CT examination bed, allowing the patient to be moved to the CT examination bed smoothly and accurately.

[0064] When the rotating frame 702 rotates to adapt to the concave surface of the CT examination bed, the adjustment component 4 can provide a stable supporting force to ensure that the rotation angle of the rotating frame 702 is accurate and stable, thereby ensuring the safety and accuracy of the entire moving process.

[0065] As an implementation method, Figure 4 As shown, further:

[0066] The lifting assembly 6 includes a first motor 601, a connecting frame 602, a support platform 604 and a guide rod 606. A plurality of guide rods 606 are connected to the lower surface of the support platform 604. The guide rods 606 are slidably connected to the top of the frame 1.

[0067] The connecting frame 602 is connected to the lower surface of the support platform 604, the first motor 601 is installed on the upper surface of the frame 1, the connecting frame 602 is connected to the lower surface of the support platform 604, and a screw 603 is installed on the output shaft of the first motor 601. The screw 603 passes through the bottom of the connecting frame 602 and is threadedly connected.

[0068] In this embodiment, the purpose of the above-mentioned setting is that when the first motor 601 is started, it drives the screw 603 to rotate, and the guide rod 606 plays a guiding and supporting role. The support platform 604 can move up and down stably when the screw 603 rotates. When the screw 603 rotates, the screw 603 is threadedly connected to the connecting frame 602, and the connecting frame 602 drives the support platform 604 to move up and down along the guide rod 606, thereby realizing the lifting function.

[0069] As an implementation method, Figure 4 and Figure 6 As shown, further:

[0070] The two ends of the support platform 604 are respectively provided with tooth grooves 605 , and the moving component 7 cooperates with the tooth grooves 605 .

[0071] In this embodiment, the purpose of the above arrangement is that the tooth groove 605 supports and moves the moving component 7 .

[0072] As an implementation method, Figure 6 As shown, further:

[0073] The moving assembly 7 also includes a gear 703 and a motor 705. The moving frame 701 is slidably connected in the tooth groove 605. The motor 705 is installed inside one end of the moving frame 701. The output shaft of the motor 705 passes through the moving frame 701 and is installed with a gear 703. The gear 703 and the tooth groove 605 are meshed with each other.

[0074] In this embodiment, the purpose of the above arrangement is that when the motor 705 is started, the gear 703 is driven to rotate. Since the gear 703 and the tooth groove 605 are meshed with each other, the movable frame 701 can slide in the tooth groove 605, thereby realizing the horizontal movement of the movable component 7 along the support platform 604.

[0075] As an implementation method, Figure 6 As shown, further:

[0076] Enclosures 704 are respectively installed on the tops of the movable frame 701 and the rotating frame 702 .

[0077] In this embodiment, the purpose of the above-mentioned setting is that when the patient is moved to the mobile frame 701 or the rotating frame 702, the enclosure 704 can provide a certain degree of blocking for the patient on all sides, thereby improving the safety of the patient during the movement. A plurality of rubber strips 501 are provided on the outer wall of the conveyor belt 5 to play an anti-slip role.

[0079] A sliding groove is provided at the bottom of the rotating frame 702, and the adjustment component 4 includes a cylinder 401, a rotating rod 402 is rotatably connected to the output end of the cylinder 401, a long rod 403 is rotatably connected to the top of the rotating rod 402, and sliding blocks 404 are respectively connected to the two ends of the long rod 403, and the sliding blocks 404 are slidably connected to the sliding groove.

[0080] In this embodiment, the purpose of the above-mentioned arrangement is that the adjustment component 4 at the bottom of the rotating frame 702 is used to adjust the posture of the rotating frame 702 to adapt to the concave surface of the CT examination bed. The output end of the cylinder 401 is rotatably connected to the rotating rod 402, and the top of the rotating rod 402 is rotatably connected to the long rod 403. The sliding blocks 404 at both ends of the long rod 403 are slidably connected to the sliding groove at the bottom of the rotating frame 702. When the cylinder 401 is extended or retracted, the sliding block 404 slides in the sliding groove through the transmission of the rotating rod 402 and the long rod 403, thereby driving the rotating frame 702 to rotate relative to the mobile frame 701 to adapt to the concave shape of the CT examination bed.

[0081] As an implementation method, Figure 7 and Figure 8 As shown, further:

[0082] Cylinders 8 are connected to the inner walls of both sides of the mobile frame 701 and the rotating frame 702 respectively. The top of the cylinder 8 is connected to a plurality of connecting blocks, and the top of the connecting block is rotatably connected to a rotating wheel 9.

[0083] In this embodiment, the purpose of the above-mentioned arrangement is that when the patient moves in the mobile frame 701 or the rotating frame 702, the rotating wheel 9 can roll, thereby making the patient's movement smoother. At the same time, the patient's own weight squeezes the conveyor belt 5. During the rotation of the rotating wheel 9, a roller massage is performed on the patient's back, which has the effect of relieving stress and relaxing the patient.

[0086] In this embodiment, the purpose of the above-mentioned setting is that the output shaft of the second motor 11 is connected to one of the rollers 10, and the other roller 10 and this roller 10 jointly support the conveyor belt 5. When the second motor 11 is started, the roller 10 connected thereto is driven to rotate. Since the conveyor belt 5 is connected to the outer walls of the two rollers 10, the conveyor belt 5 starts to run, thereby realizing auxiliary movement of the patient. A number of rubber strips 501 are arranged on the outer wall of the conveyor belt 5 to play an anti-slip role.

[0087] As an implementation method, Figure 1 and Figure 3 As shown, further:

[0088] The bottom of the frame 1 is rotatably connected to a wheel 2 , and a friction limit assembly 3 is installed at the bottom of the frame 1 .

[0089] In this embodiment, the purpose of the above arrangement is that the wheels 2 rotatably connected to the bottom of the frame 1 facilitate the movement of the entire bed-entering auxiliary mechanism, and the friction limit assembly 3 is used to control the movement state of the frame 1.

[0090] As an implementation method, Figure 3 As shown, further:

[0091] The friction limit assembly 3 includes a sliding rod 301, which is slidably connected to the frame 1. The bottom end of the frame 1 is connected to a friction plate 303. A spring 302 is arranged between the friction plate 303 and the frame 1. A connecting rod 304 is connected to the top outer wall of the sliding rod 301. A limiting rod 305 is slidably connected to the outer wall of the connecting rod 304. A plurality of limiting holes are arranged on the outer wall of the frame 1. One end of the limiting rod 305 is inserted into the limiting hole.

[0092] In this embodiment, the purpose of the above arrangement is that the wheels 2 rotatably connected to the bottom of the frame 1 facilitate the movement of the entire bed-entering auxiliary mechanism, and the friction limit assembly 3 is used to control the moving state of the frame 1. The sliding rod 301 in the friction limit assembly 3 is slidably connected to the frame 1, and a spring 302 is arranged between the friction plate 303 and the frame 1. When it is necessary to limit the movement of the frame 1, the connecting rod 304 and the limit rod 305 at the top of the sliding rod 301 are operated to insert one end of the limit rod 305 into the limit hole on the outer wall of the frame 1, and at the same time, the sliding rod 301 presses down the friction plate 303 to increase the friction between the friction plate 303 and the ground, thereby limiting the movement of the frame 1;

[0093] When the frame 1 needs to be moved, the operation is reversed to reduce the friction between the friction plate 303 and the ground, and the wheels 2 can rotate normally to achieve the movement of the frame 1.

[0094] Working principle: When the first motor 601 is started, it drives the screw rod 603 to rotate, and the guide rod 606 plays a guiding and supporting role. The support platform 604 can stably move up and down when the screw rod 603 rotates. When the screw rod 603 rotates, the screw rod 603 is threadedly connected with the connecting frame 602, and the connecting frame 602 drives the support platform 604 to move up and down along the guide rod 606, thereby realizing the lifting function;

[0095] When the motor 705 is started, the gear 703 is driven to rotate. Since the gear 703 and the tooth groove 605 are meshed with each other, the movable frame 701 can slide in the tooth groove 605, thereby realizing the horizontal movement of the movable assembly 7 along the support platform 604;

[0096] The adjustment assembly 4 at the bottom of the rotating frame 702 is used to adjust the posture of the rotating frame 702 to adapt to the concave surface of the CT examination bed. The output end of the cylinder 401 is rotatably connected to the rotating rod 402, and the top of the rotating rod 402 is rotatably connected to the long rod 403. The sliding blocks 404 at both ends of the long rod 403 are slidably connected to the sliding groove at the bottom of the rotating frame 702. When the cylinder 401 is extended or retracted, the sliding blocks 404 slide in the sliding groove through the transmission of the rotating rod 402 and the long rod 403, thereby driving the rotating frame 702 to rotate relative to the mobile frame 701 to adapt to the concave shape of the CT examination bed;

[0097] The output shaft of the second motor 11 is connected to one of the roller shafts 10, and the other roller shaft 10 and the roller shaft 10 jointly support the conveyor belt 5. When the second motor 11 is started, the roller shaft 10 connected thereto is driven to rotate. Since the conveyor belt 5 is connected to the outer walls of the two roller shafts 10, the conveyor belt 5 starts to run, thereby realizing auxiliary movement of the patient;

[0098] When the patient is moved to the mobile rack 701 or the rotating rack 702, the enclosure 704 can block the patient to a certain extent on all sides to improve the safety of the patient during the movement. A plurality of rubber strips 501 are arranged on the outer wall of the conveyor belt 5 to play an anti-slip role;

[0099] When the patient moves in the mobile frame 701 or the rotating frame 702, the rotating wheel 9 can roll, so that the patient's movement is smoother. At the same time, the patient's own weight squeezes the conveyor belt 5. During the rotation of the rotating wheel 9, the patient's back is massaged by a roller, which relieves the patient's pressure and relaxes him.

[0100] The wheels 2 rotatably connected at the bottom of the frame 1 facilitate the movement of the entire bed-entering auxiliary mechanism, and the friction limit assembly 3 is used to control the moving state of the frame 1. The sliding rod 301 in the friction limit assembly 3 is slidably connected to the frame 1, and a spring 302 is arranged between the friction plate 303 and the frame 1. When it is necessary to limit the movement of the frame 1, the connecting rod 304 and the limit rod 305 at the top of the sliding rod 301 are operated to insert one end of the limit rod 305 into the limit hole on the outer wall of the frame 1, and at the same time, the sliding rod 301 presses down the friction plate 303 to increase the friction between the friction plate 303 and the ground, thereby limiting the movement of the frame 1;

[0101] When the frame 1 needs to be moved, the operation is reversed to reduce the friction between the friction plate 303 and the ground, and the wheels 2 can rotate normally to achieve the movement of the frame 1.
