Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and particularly relates to a nuclear medicine isolation screen. Background Art

[0002] Nuclear medicine is a new discipline that uses nuclear technology to diagnose, treat and study diseases. It is the product of the combination of modern scientific and technological fields such as nuclear technology, electronic technology, computer technology, chemistry, physics and biology. Nuclear medicine can be divided into two categories, namely clinical nuclear medicine and basic nuclear medicine or experimental nuclear medicine.

[0003] The utility model with the publication number CN209747141U discloses a nuclear medicine isolation screen, which includes an arc-shaped outer cover and a storage device connected to the arc-shaped outer cover; the arc-shaped outer cover includes an inner side wall and an outer side wall corresponding to the inner side wall, a lead plate is arranged between the inner side wall and the outer side wall, and an operating device is arranged on the lead plate and the inner side wall; the operating device includes an operating plate slidably connected to the arc-shaped outer cover and a first transmission structure cooperating with the operating plate. When using this device by nuclear medicine staff, because the lengths of each person's arms are different, the rotating table can be rotated. The rotating table will drive the support box fixedly connected to the support plate to rotate, and the rotating disk on the support box will also rotate accordingly, turning the rotating disk to a position suitable for oneself; when nuclear medicine staff view radioactive drugs or medical devices and patients undergoing nuclear treatment, the limit pin can be pulled out from the limit right-angle plate and the support block, and then the arc-shaped outer cover can be used alone. Its operation for closing or opening the overall device is rather troublesome and not conducive to frequent daily use. Content of the Utility Model

[0004] The purpose of the utility model is to provide a nuclear medicine isolation screen, which solves the existing problems.

[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0006] The utility model is a nuclear medicine isolation screen, which includes an arc-shaped outer cover. A hydraulic cylinder is arranged at the bottom inside the arc-shaped outer cover, and the output end of the hydraulic cylinder is fixedly connected with a seat. A closing mechanism is arranged inside the arc-shaped outer cover. The closing mechanism includes a cover door and a slot. The cover door is slidably connected inside the arc-shaped outer cover. A transparent window is opened on the surface of the cover door. One end of the cover door away from the inside of the arc-shaped outer cover is fixedly connected with an insertion block. A groove is opened on the surface of the insertion block. A telescopic spring is arranged inside the groove. An arc-shaped block is slidably connected inside the groove through the telescopic spring. The slot is opened at one end of the arc-shaped outer cover away from the cover door. A clamping groove is opened on the inner wall of the slot. A resisting rod penetrates through and is slidably connected at one end of the slot away from the cover door. A buffer mechanism is arranged inside the slot.

[0007] Furthermore, the size of the insertion block corresponds to the size of the slot opening, and the depth of the slot is greater than the length of the insertion block, so that the insertion block can be inserted into the slot.

[0008] Furthermore, the opening size of the groove is equal to the opening size of the card slot, and the arc-shaped block is made of stainless steel. The arc-shaped block can enter the card slot, and the arc-shaped block made of stainless steel has high strength and is not easy to rust and damage.

[0009] Furthermore, the arc surface of the arc-shaped block faces the outside of the arc-shaped outer cover, and the depth of the groove is greater than the length of the arc-shaped block. When the arc surface of the arc-shaped block is squeezed, it will move into the groove, and the arc-shaped block can be completely retracted into the groove.

[0010] Furthermore, the buffer mechanism includes a buffer spring, a buffer plate and a speed bump. The buffer plate is slidably connected to the inside of the slot through the buffer spring. A contact rod is fixedly connected to the side surface of the buffer plate, and the speed bump is fixedly connected to the inner side wall of the slot.

[0011] Furthermore, the buffer plate is square as a whole, and the length of the contact rod is greater than the distance between the speed bumps on the side surface of the buffer plate. When the buffer plate moves, it will drive the contact rod to move and contact the speed bump.

[0012] Furthermore, both the buffer plate and the speed bump are made of rubber. The overall shape of the speed bump is semi-cylindrical. The rubber buffer plate itself plays a certain buffering role, and a certain resistance will be generated when the contact rod presses against the speed bump.

[0013] The utility model has the following beneficial effects:

[0014] 1. By providing a closing mechanism, when it is necessary to close the arc-shaped outer cover as a whole, the cover door can be pulled so that the insertion block at its side end is inserted into the slot. At this time, the arc-shaped block will automatically snap into the card slot, making the cover door unable to be opened again. When it is necessary to open the cover door, pressing the abutting rod can drive the arc-shaped block out of the card slot, and then the cover door can be pulled open.

[0015] 2. By providing a buffer mechanism, through the cooperation of components such as the buffer plate, buffer spring and contact rod, it can play a buffering role when closing the cover door, preventing damage to the cover door caused by the impact generated by excessive force when closing the cover door.

[0016] Of course, when implementing any product of the utility model, it is not necessarily required to achieve all the above advantages at the same time. Description of the Drawings

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0027] Please refer to Figures 1-6, the utility model relates to a nuclear medicine isolation screen, which comprises an arc-shaped outer cover 1. A hydraulic cylinder 2 is arranged at the inner bottom of the arc-shaped outer cover 1. The output end of the hydraulic cylinder 2 is fixedly connected with a seat 3. A closing mechanism 4 is arranged inside the arc-shaped outer cover 1. The closing mechanism 4 comprises a cover door 41 and a slot 46. The cover door 41 is slidably connected inside the arc-shaped outer cover 1. A transparent window 42 is arranged on the surface of the cover door 41. One end of the cover door 41 far away from the inside of the arc-shaped outer cover 1 is fixedly connected with a plug 49. A groove 43 is arranged on the surface of the plug 49. A telescopic spring 44 is arranged inside the groove 43. An arc-shaped block 45 is slidably connected inside the groove 43 through the telescopic spring 44. The slot 46 is arranged at one end of the arc-shaped outer cover 1 far away from the cover door 41. A clamping groove 47 is arranged on the inner wall of the slot 46. A resisting rod 48 penetrates and is slidably connected at one end of the slot 46 far away from the cover door 41. A buffer mechanism 5 is arranged inside the slot 46.

[0028] The size of the plug 49 corresponds to the opening size of the slot 46. The depth of the slot 46 is greater than the length of the plug 49, and the plug 49 can be inserted into the slot 46.

[0029] The opening size of the groove 43 is equal to the opening size of the clamping groove 47. The arc-shaped block 45 is made of stainless steel. The arc-shaped block 45 can enter the clamping groove 47. The arc-shaped block 45 made of stainless steel has high strength and is not easy to rust and damage.

[0030] The arc surface of the arc-shaped block 45 faces the outside of the arc-shaped outer cover 1. The depth of the groove 43 is greater than the length of the arc-shaped block 45. When the arc surface of the arc-shaped block 45 is extruded, it will move into the groove 43, and the arc-shaped block 45 can be completely retracted into the groove 43.

[0031] The buffer mechanism 5 comprises a buffer spring 51, a buffer plate 52 and a speed bump 54. The buffer plate 52 is slidably connected inside the slot 46 through the buffer spring 51. A contact rod 53 is fixedly connected to the side surface of the buffer plate 52. The speed bump 54 is fixedly connected to the inner side wall of the slot 46.

[0032] The buffer plate 52 is integrally square. The length of the contact rod 53 is greater than the distance between the speed bumps 54 on the side surface of the buffer plate 52. When the buffer plate 52 moves, it will drive the contact rod 53 to move and contact with the speed bump 54.

[0033] Both the buffer plate 52 and the speed bump 54 are made of rubber. The overall shape of the speed bump 54 is semi-cylindrical. The rubber buffer plate 52 itself plays a certain buffering role, and a certain resistance will be generated when the contact rod 53 is squeezed with the speed bump 54.

[0034] A specific application of this embodiment is as follows: When the whole device needs to be used, let the patient enter the inner side of the arc-shaped outer cover 1 and sit on the seat 3. The height of the seat 3 can be adjusted by starting the hydraulic cylinder 2. When isolation treatment is needed for the patient, pull the cover door 41 to close the arc-shaped outer cover 1. At this time, the insertion block 49 on the side end of the cover door 41 will be inserted into the slot 46. At the beginning, the arc surface of the arc-shaped block 45 will be squeezed and thus retracted into the groove 43, and the telescopic spring 44 will be tightened. When the groove 43 fits with the card slot 47, the telescopic spring 44 rebounds to drive the arc-shaped block 45 to be stuck into the card slot 47, making the cover door 41 unable to be opened again. The internal patient can be observed through the transparent window 42. When the isolation treatment is over, the arc-shaped block 45 can be extruded out of the card slot 47 by pressing the abutting rod 48, so as to open the cover door 41 again. During the process of closing the cover door 41 so that the insertion block 49 is inserted into the slot 46, the insertion block 49 will contact the buffer plate 52. At this time, the buffer plate 52 and the buffer spring 51 will play a buffering role. At the same time, the movement of the buffer plate 52 will drive the contact rod 53 to squeeze the speed bump 54 to generate resistance, thereby further improving the buffering effect and preventing damage to the cover door 41 caused by the impact when closing the cover door 41 with too much force.
