Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of medical instruments, more particularly, relates to a medical carrier horizontal movement mechanism and medical carrier. BACKGROUND

[0002] With the development of medicine and the progress of science and technology, medical imaging equipment has made great progress. The existing medical imaging equipment generally includes a patient carrier such as a scanning bed, and the carrier can move up and down and horizontally relative to the base.

[0003] In the patient carrier with the base movement dimension, the contact surface of the guide rail is usually designed to face upward, and the contact surface of the sliding block faces downward. In order to shield the guide rail from being exposed to the outside, and to shield the internal structure of the base, the following two structures are usually used as shielding structures: 1. Roller shutter as shielding structure, because the base is near the patient upper carrier stepping area, and in the actual operation process of the hospital, patient family members / nurses are often introduced as helpers to assist patients in loading the carrier and positioning, which causes the roller shutter of the base to be stepped on to varying degrees, and dust and foreign matter can easily enter the roller shutter, which has high requirements for the reliability of the roller shutter. 2. Organ type guide rail protective cover as shielding structure, the organ type guide rail protective cover cannot withstand large external force, and is required to meet the requirements of the relevant regulations and standards of the capture area, so the gap needs to be as small as possible. The smaller gap results in a thinner structure unit, which puts higher requirements on the structural strength of the protective cover.

[0004] Moreover, these two shielding structures have a common technical problem: the need for storage space. The roller shutter usually needs to use a roll-type storage box to store the roller shutter structure. The organ cover also needs a certain length of space to store the organ structure of the folded part. The storage space will accordingly occupy the space in the length direction of the carrier.

DETAILED DESCRIPTION

[0034] In order to make the technical problems, technical solutions and beneficial effects of the present application clearer, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the present application.

[0035] It should be noted that when an element is referred to as being "fixed" or "disposed" on another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0037] In addition, the terms "first", "second" are only for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "multiple" is two or more, unless otherwise specifically limited.

[0038] With the development of medicine and the progress of science and technology, medical imaging equipment such as positron emission tomography (PET) and computed tomography (CT) has made great progress. The existing medical imaging equipment generally includes a patient carrier such as a scanning bed, and the carrier can move up and down and horizontally relative to the base.

[0039] At present, the patient carrier containing the base motion dimension is usually designed as the contact surface of the guide rail upward, and the contact surface of the slider downward. In order to shield the guide rail from being exposed to the outside, and to shield the internal structure of the base, the following two structures are usually used as shielding structures: 1. The roller shutter is used as a shielding structure, because the base is near the patient loading area, and the patient family members / nurses are often introduced as helpers to assist the patient in loading and positioning the carrier during the actual operation of the hospital, which causes the roller shutter of the base to be stepped on to different degrees, and dust and foreign matter can easily enter the roller shutter, so that the reliability of the roller shutter is required. 2. The organ type guide rail protective cover is used as a shielding structure, and the organ type guide rail protective cover cannot withstand large external force, and is required to meet the requirements of the relevant regulations and standards of the capture area, so the gap needs to be as small as possible. The smaller gap leads to a thinner structure unit, and higher requirements are put forward for the structural strength of the protective cover.

[0040] Moreover, the two shielding structures have a common technical problem: the need for storage space. The roller shutter usually needs to use a roll type storage box to store the roller shutter structure. The organ cover also needs a certain length space to store the folded part of the organ structure. The storage space will correspondingly occupy the space in the length direction of the carrier.

[0041] The space in the length direction of the patient carrier has a decisive influence on the length direction space of the whole machine. Smaller carrier length has great benefits for the site, especially when the user cannot provide enough site for the scanning room. For multi-modal products such as PET / CT, the large site occupation has always been the main short board of the single-dimensional horizontal motion examination bed. It is necessary to shorten the length of the examination bed. The design of avoiding the organ type guide rail protective cover and the roller shutter can effectively reduce the space occupation in the length direction.

[0042] In order to solve the above technical problems, the utility model embodiment provides a medical carrier horizontal motion mechanism and a medical carrier. The horizontal motion mechanism comprises a base 10 and a stand 20 connected to the base 10, the base 10 is at least partially wrapped by the stand 20, thereby forming a "sky covering ground" structure, the sliding fit structure between the base 10 and the stand 20 is arranged on the extension structure 12 and the covering structure 22 respectively, the first sliding fit part 31 and the second sliding fit part 32 are hiddenly arranged and will not be exposed on the top of the base 10, which can reduce the invasion of dust and foreign matter, and there is no need to design the organ type guide rail protective cover, the roller shutter and other structures, so that the space occupation in the length direction can be reduced.

[0045] The base 10 is fixedly arranged, and the column 20 slides relative to the base 10 in a horizontal direction. The sliding fitting structure between the column 20 and the base 10 can be understood as a sliding rail, a sliding block, a sliding groove or the like. Since the column at least partially wraps the base 10, the sliding fitting structure can be shielded, without the need to open a gap on the top of the base 10 or to arrange a shielding structure.

[0078] In some embodiments of the utility model, please refer to Figure 3 The medical carrier horizontal movement mechanism further comprises a driving assembly 40, the driving assembly 40 comprises a driver 41, a synchronous belt assembly 43 and a clutch 42, the driver 41 is used for driving the synchronous belt assembly 43, the belt 432 of the synchronous belt assembly 43 is fixedly connected with the stand column 20, and the driver 41 is selectively in transmission connection with the synchronous belt assembly 43 or separated from each other through the clutch 42.

[0079] The driving assembly 40 is used for driving the column 20 to move in the horizontal direction, and the driving assembly 40 can output linear motion. The driver 41 is selectively connected or separated from the synchronous belt assembly 43 through the clutch 42, and it can be understood that the driver 41 can be connected or separated from the synchronous belt assembly 43 through the clutch 42. When the driver 41 is connected to the synchronous belt assembly 43 through the clutch 42, the motion output shaft 411 of the driver 41, the clutch 42 and the pulley 431 of the synchronous belt assembly 43 are sequentially connected in transmission, and the inner ring 421 and the outer ring 422 of the clutch 42 are engaged with each other, so that the column 20 can be driven to move horizontally by the driver 41. When the driver 41 is separated from the synchronous belt assembly 43 through the clutch 42, the inner ring 421 and the outer ring 422 of the clutch 42 are separated from each other, and the power of the driver 41 cannot be transmitted to the synchronous belt assembly 43.

[0080] Through the setting of the clutch 42, the column 20 can be selectively driven by the driving assembly 40. The column 20 can be directly driven to move by the driving assembly 40, or the column 20 can be moved by an external force. When the column 20 is moved by an external force, the inner ring 421 and the outer ring 422 of the clutch 42 are separated from each other, and the external pushing force required by the column 20 is small, and the operation is more labor-saving without overcoming the internal resistance of the driver 41.

[0081] In some embodiments of the utility model, please refer to Figure 3 The synchronous belt assembly 43 is arranged between the driver 41 and the clutch 42. The axial direction of the driver 41 (the axial direction of the motion output shaft 411), the axial direction of the clutch 42 and the axial direction of the synchronous belt assembly 43 (the axial direction of the pulley 431) are arranged in parallel or coincide with each other, and in the axial direction, the synchronous belt assembly 43 is arranged between the driver 41 and the clutch 42.

[0082] In the related art, the general structure sequence of the driving assembly is: synchronous belt assembly-clutch-driver. However, in the scene where the synchronous belt is placed on one side, the single-side space is greatly occupied, which leads to that the width of the patient carrier is too wide and greatly affects the space occupation. In the embodiment, the synchronous belt assembly 43 is located in the middle part, and the occupation of the single-side space is smaller, and the layout is more reasonable.

[0083] In some embodiments, please refer to Figure 3 and Figure 4The hollow structure of the pulley 431 can be understood as that the pulley 431 has a central hole 4311 penetrating through both ends of the pulley 431 in the axial direction, and the motion output shaft 411 of the driver 41 penetrates through the central hole 4311 and is connected with the inner rotor ring 421. When the column 20 is driven to move by the driving assembly 40, the motion output shaft 411 of the driver 41 drives the inner rotor ring 421 to move, the inner rotor ring 421 and the outer rotor ring 422 are engaged with each other, the power is transmitted to the pulley 431, and the column 20 is driven to move horizontally by the synchronous belt assembly 43. When the column 20 is driven to move by the external thrust, the inner rotor ring 421 and the outer rotor ring 422 are separated from each other, the transmission connection between the synchronous belt assembly 43 and the driver 41 is disconnected, and only the inner resistance of the synchronous belt assembly 43 needs to be overcome to drive the column 20.

[0084] By setting the pulley 431 as a hollow structure, the motion output shaft 411 of the driver 41 can penetrate through the pulley 431 and be connected with the inner rotor ring 421 of the clutch 42, so that the synchronous belt assembly 43 is arranged between the driver 41 and the clutch 42.

[0085] In some embodiments, the driver 41 includes a motor and a speed reducer, the motor shaft is connected with the motion input shaft of the speed reducer, and the motion output shaft of the speed reducer is the motion output shaft 411 of the driver 41.

[0086] Optionally, the motion output end of the motor is provided with an encoder, generally an absolute encoder, for detecting the number of rotations of the motor.

[0087] In some embodiments, the driving assembly 40 further includes a horizontal position sensor for detecting the absolute position of the horizontal degree of freedom of the carrier body. The horizontal position sensor can be an encoder, such as a magnetic grating encoder, a wire-drawing encoder, etc.

[0088] In some embodiments, the axial end of the pulley 431 is fixedly connected with the outer rotor ring 422 of the clutch 42, and the axial other end of the pulley 431 is connected with the driver 41 through a bearing, that is, the axial other end of the pulley 431 is rotationally supported on the housing structure of the driver 41 through the bearing. In this way, the bearing can be arranged on the driver 41 to support the pulley 431, so that the rotation of the pulley 431 is more stable.

[0089] In some embodiments of the utility model, please refer to Figure 5The bottom of the column 20 is provided with a sensor 23 for detecting obstacles. The bottom of the column 20 is arranged close to the ground. The sensor 23 is used to detect obstacles, and when an obstacle is detected, an alarm can be sounded and the column 20 can be braked and the like.

[0090] The column 20 has a risk of collision with an operator, a patient's family member, or a surrounding structure during movement, and the sensor 23 can remind the user of the risk of collision and reduce the possibility of collision.

[0091] In some embodiments, the sensor 23 is a photoelectric sensor, and a suitable detection area (for example, about 50 mm) is designed. When the column 20 moves horizontally, if a foreign object that is easy to get entangled is detected, the movement is immediately stopped until the operator removes the risk of foreign objects, and the error is then cleared.

[0092] Optionally, the photoelectric sensor 23 is a diffuse reflection photoelectric sensor, which can adjust the detection area to prevent the sensing distance from being too large or from being frequently reported as an error due to conflict with machine components. The sensor 23 can be selected to be resistant to interference, and can be used without affecting the function under high brightness and high complexity of light conditions.

[0093] In some embodiments, the column 20 is provided with a sensor 23 at each of the four corners, which can detect obstacles at each position and reduce the risk of collision.

[0094] In some embodiments of the utility model, the surface of the column 20 close to the ground is smoothly arranged, which can be understood as that the edges, corners and the like of the column 20 close to the ground are all smooth structures such as round corner structures, which can prevent scratching people, and even if the column 20 collides with an object or a person, the collision will not be too serious.

[0095] Please refer to Figure 5 The utility model also provides a medical carrier, and the medical carrier comprises the medical carrier horizontal movement mechanism in any one of the above embodiments. The medical carrier can further comprise a carrier body, and the carrier body is fixedly connected with the column 20, so that the carrier body can move horizontally.

[0096] The medical carrier provided by the utility model adopts the medical carrier horizontal movement mechanism, the medical carrier horizontal movement mechanism comprises a base 10 and a stand 20 which is slidably arranged on the base 10, the base 10 comprises a first main body part 11 and an extension structure 12, the stand 20 comprises a second main body part 21 and a covering structure 22, and the covering structure 22 can cover the edge of the base 10. By arranging the first sliding fitting part 31 and the second sliding fitting part 32 on the extension structure 12 and the covering structure 22 respectively, the first sliding fitting part 31 and the second sliding fitting part 32 are arranged in a hidden mode and will not be exposed on the top of the base 10, so that the external dust can be reduced, and it is unnecessary to design a shielding structure and consider the structural strength and dustproof capacity of the shielding structure. By arranging the covering structure 22 to cover the edge of the base 10, the upper surface of the base 10 is not slitted, and the invasion of foreign matters into the base 10 is avoided.

[0097] The above merely describes the preferred embodiments of the utility model and is not intended to limit the utility model, and any modification, equivalent replacement and improvement made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
