Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, and in particular to a CT examination bed. Background Art

[0002] The CT examination bed is an important component of the computed tomography (CT) equipment. It is responsible for smoothly and accurately moving the patient into and out of the scanning area during the CT scanning process. The CT examination bed is usually equipped with an advanced control system that can make fine position adjustments according to the doctor's instructions to ensure the accuracy of the scan and the comfort of the patient.

[0003] Since CT scans use X-rays to penetrate the body and capture images of different tissues that absorb different amounts of X-rays, a certain amount of radiation is generated in the process. Therefore, when patients undergo CT scans clinically, they are required to wear lead suits. However, lead suits are very heavy, especially for frail elderly people. Not only do they consume a lot of physical strength and time, but they also cause oppression to the patient, increasing discomfort and inconvenience in movement.

[0004] In addition, when patients undergo CT examinations on existing CT examination beds, they usually need to lie on an examination bed covered with a sheet. Medical institutions generally decide whether to change the sheet based on the patient's usage and the infection control standards in the hospital. Therefore, most CT examination beds do not have the function of automatically changing the sheet. Especially for CT examination beds with lower infection control standards, medical staff usually need to manually change and disinfect them, which has low replacement efficiency and large workload. In order to solve the shortcomings of the existing technology, we propose a CT examination bed. Summary of the invention

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. In the present invention, wide sheets and narrow sheets are arranged on the top of the movable bed board to replace the sheets horizontally. Compared with the traditional vertical replacement of sheets, faster replacement of sheets can be achieved, and the original depression on the top of the movable bed board is compensated, which causes the sheets to be pressed and deformed when the patient lies on the top of the movable bed board, resulting in the deviation of the sheets, affecting the rolling effect of the sheets.

[0020] 2. In the present invention, a segmented design of wide sheets and narrow sheets is utilized so that the length of the first winding roller is longer than that of the second winding roller.

Therefore, when a CT examination bed with a lower infection control standard is used, simple disinfection can be achieved between different patients, thereby reducing the frequency of patient infection.

[0023] 5. In the present invention, the first electric telescopic rod is controlled to contract so that the first sliding cross frame slides on the first supporting longitudinal rod. At this time, the first lead cloth will be affected by gravity, and the middle part will begin to sag and press on the patient's body. As the first electric telescopic rod contracts, the first lead cloth will be spread flat on the patient's body to cover the parts of the patient that do not need to be examined. The patient does not need to wear a lead suit, thereby improving the patient's examination efficiency.

[0024] 6. In the present invention, the first fixing plate and the second fixing plate are unfolded, and the first lead cloth and the second lead cloth are combined to increase the range of shielding of the patient's body parts. When the first shielding member and the second shielding member are unfolded, the spring button is pressed to disengage from the inside of the positioning hole, and the first shielding member and the second shielding member are separated, thereby shielding both ends of the patient's examination part, so that the shielding device can be freely adjusted according to the examination part, and is more flexible to use.

DETAILED DESCRIPTION

[0036] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0037] Embodiment 1, as Figure 1 - Figure 4 As shown, a CT examination bed comprises an examination bed body 1, a bed sheet changing device 3 is arranged on the top of the examination bed body 1, and a shielding device 2 is slidably installed on the outer surface of the bed sheet changing device 3;

[0038] The inspection bed body 1 includes a lifting base 11, a fixed bed board 12 is fixedly installed on the top of the lifting base 11, a movable bed board 13 is arranged on the top of the fixed bed board 12, a head bracket 14 is fixedly connected to the right end of the movable bed board 13, a fixing frame 16 is fixedly installed on both sides of the left end of the fixed bed board 12, a first sliding track 17 is fixedly installed on the side of the fixing frame 16, and a storage box 15 is fixedly installed on the top of the left end of the fixed bed board 12;

[0039] The bed sheet changing device 3 includes two storage boxes 31, which are fixedly mounted on both sides of the bottom of the movable bed board 13, and the side of the storage box 31 is fixedly mounted with a second sliding track 33, the position of the second sliding track 33 is flush with the first sliding track 17, and is located on one side of the first sliding track 17, and the top of the storage box 31 is hingedly connected with a box cover 32, and the box cover 32 is fixedly connected to one side of the storage box 31 by bolts, and forms a movable groove 310 with the top of the storage box 31, and the storage box 31 is internally connected to the storage box 31. A support frame 37 is fixedly installed at the lower end, and a first winding roller 38 and a second winding roller 39 are rotatably installed on both sides of the support frame 37, and a winding motor 36 is fixedly installed on both sides of the storage box 31, and the winding motors 36 on both sides are fixedly connected to the first winding roller 38 and the second winding roller 39 respectively, the outer surface of the first winding roller 38 is wrapped with a wide sheet 34, and the outer surface of the second winding roller 39 is wrapped with a narrow sheet 35, a disinfection component 4 is fixedly connected to the middle of the storage box 31, and a through groove is opened at the bottom of the storage box 31.

[0040] The bottom of the storage box 31 is provided with a through groove to facilitate the volatilization of the disinfectant and improve the drying effect of the rolled-up bed sheet.

[0041] Among them, the support frame 37 is "Z"-shaped and is located on the left side of the storage box 31. The wide sheet 34 and the narrow sheet 35 are respectively movably connected to the top of the movable bed board 13, and the left side of the wide sheet 34 covers the right side of the narrow sheet 35.

[0042] By setting the support frame 37 in a "Z" shape, the first winding roller 38 and the second winding roller 39 can be overlapped with each other, so that the left side of the wide sheet 34 covers the right side of the narrow sheet 35, avoiding the presence of gaps when the wide sheet 34 and the narrow sheet 35 cover the top of the movable bed board 13, resulting in the inability to fully cover the movable bed board 13.

[0043] The two storage boxes 31 are fixedly installed on both sides of the bottom of the movable bed board 13. When changing the bed sheets, the two winding motors 36 on both sides of the storage box 31 at one end of the rolled-up bed sheets are started synchronously, so that the first winding roller 38 and the second winding roller 39 are used to wind up the bed sheets. At this time, the first winding roller 38 and the second winding roller 39 inside the storage box 31 at the other end are unwound synchronously to realize the replacement of the bed sheets.

[0044] The wide bed sheet 34 and the narrow bed sheet 35 are arranged on the top of the movable bed board 13 to perform horizontal bed sheet replacement. Compared with the traditional vertical bed sheet replacement, faster bed sheet replacement can be achieved and the original depression on the top of the movable bed board 13 can be compensated. When the patient lies on the top of the movable bed board 13, the bed sheet is pressed by the patient and deformed, causing the bed sheet to shift, affecting the rolling effect of the bed sheet (in order to facilitate the patient to lie in the middle of the movable bed board 13, the examination bed is usually designed with a depression on the top of the movable bed board 13, so that the patient can lie in the center of the movable bed board 13, which is convenient for CT examination).

[0045] By utilizing a segmented design of wide sheets 34 and narrow sheets 35, the support frame 37 is located on the left side of the storage box 31, so that the length of the first winding roller 38 is longer than the length of the second winding roller 39. When it comes to children or patients with smaller stature, the first winding roller 38 can be wound up and replaced alone, thereby reducing the loss of sheets.

[0046] Embodiment 2, as Figure 1 , Figure 4 - Figure 6As shown, the disinfection component 4 includes a liquid storage tank 41, which is fixedly installed in the middle of the storage box 31, and a liquid inlet 42 is arranged on the top of the liquid storage tank 41. A first spray nozzle 45 is fixedly installed on the lower side of the right end of the liquid storage tank 41, and a limiting groove 43 is formed between the first spray nozzle 45 and the liquid storage tank 41. A first solenoid valve 44 is fixedly connected to the left side of the liquid storage tank 41, and the first solenoid valve 44 is connected to the first spray nozzle 45. The outer surface of the first spray nozzle 45 is sleeved with a first wiping cotton 46, and a second solenoid valve 47 is fixedly connected to the right side of the liquid storage tank 41.

The disinfection component 4 is fixed in the middle of the storage box 31, so that the first winding roller 38 and the second winding roller 39 are respectively located on both sides of the disinfection component 4. The disinfection component 4 does not affect the replacement of the wide sheets 34 and the narrow sheets 35 wound on the outer surfaces of the first winding roller 38 and the second winding roller 39. When replacing the sheets, the box cover 32 is opened by bolts to realize the removal and replacement of the wide sheets 34 and the narrow sheets 35.

[0048] Among them, the wide sheet 34 is movably sleeved inside the limiting groove 43 and slides on the side of the first wiping cotton 46, and the side of the narrow sheet 35 is slidably installed on the outer surface of the second wiping cotton 49. The positions of the first wiping cotton 46 and the second wiping cotton 49 correspond to the positions of the first winding roller 38 and the second winding roller 39 respectively.

[0049] When changing the bed sheets, the two winding motors 36 on both sides of the storage box 31 at one end of the rolled-up bed sheets are started synchronously, so that the first winding roller 38 and the second winding roller 39 roll up the bed sheets. At the same time, the first solenoid valve 44 and the second solenoid valve 47 are started, so that the disinfectant inside the liquid storage tank 41 is sprayed out through the first spray nozzle 45 and the second spray nozzle 48 to moisten the first wiping cotton 46 and the second wiping cotton 49, and the wide bed sheet 34 and the narrow bed sheet 35 are wiped by the first wiping cotton 46 and the second wiping cotton 49 to achieve disinfection of the rolled-up bed sheets.

[0050] When using a CT examination bed with a lower infection control standard, after the patient uses it, when changing the bed sheet, the two winding motors 36 on both sides of the storage box 31 at the right end of the rolled bed sheet are started synchronously, so that the first winding roller 38 and the second winding roller 39 wind the bed sheet to the right, and the first solenoid valve 44 and the second solenoid valve 47 on the right end are started, so that the disinfectant inside the liquid storage tank 41 is sprayed through the first spray nozzle 45 and the second spray nozzle 48, and the rolled wide bed sheet 34 and the narrow bed sheet 35 are wiped by the first wiping cotton 46 and the second wiping cotton 49 to achieve disinfection of the rolled bed sheet. At this time, the first winding roller 38 and the second winding roller 39 inside the left storage box 31 are unwound synchronously to achieve the replacement of the bed sheet. After the next patient uses it, the rolled bed sheet is The two winding motors 36 on both sides of the storage box 31 at the left end are started synchronously, so that the first winding roller 38 and the second winding roller 39 wind the bed sheet to the left side, and the first solenoid valve 44 and the second solenoid valve 47 at the left end are started, so that the disinfectant inside the liquid storage tank 41 is sprayed out through the first spray nozzle 45 and the second spray nozzle 48, and the wide bed sheet 34 and the narrow bed sheet 35 rolled up on the left side are wiped by the first wiping cotton 46 and the second wiping cotton 49 to disinfect the rolled up bed sheets. At this time, the first winding roller 38 and the second winding roller 39 inside the storage box 31 on the right side are unwound synchronously to replace the bed sheets, so that when the CT examination bed with a lower infection control standard is used, simple disinfection can be achieved between different patients, thereby reducing the frequency of patient infection.

The first lead cloth 2115 and the second lead cloth 229 are combined to increase the range of covering the patient's body parts.

[0059] In addition, when the first shielding member 21 and the second shielding member 22 are unfolded, the spring button 2112 is pressed to disengage the spring button 2112 from the interior of the positioning hole 218, and the sliding main frame 212 is pulled again to make the movable inner frame 219 slide inside the fixed sleeve 214, so that the first shielding member 21 and the second shielding member 22 are separated. At this time, the sliding groove 223 at the left end of the sliding frame 222 is located on the outer surface of the fixing bolt 2111, so that the two ends of the patient's examination part can be shielded, so that the shielding device 2 can be freely adjusted according to the examination part, and the use is more flexible.

[0060] It should be noted that the present invention is a CT examination bed. When a CT examination bed with a lower infection control standard is used, after the patient uses it, when changing the bed sheet, the two winding motors 36 on both sides of the storage box 31 at the right end of the rolled bed sheet are started synchronously, so that the first winding roller 38 and the second winding roller 39 wind the bed sheet to the right, and the first solenoid valve 44 and the second solenoid valve 47 at the right end are started, so that the disinfectant inside the liquid storage tank 41 is sprayed through the first spray nozzle 45 and the second spray nozzle 48, and the rolled wide bed sheet 34 and the narrow bed sheet 35 are wiped by the first wiping cotton 46 and the second wiping cotton 49 to achieve disinfection of the rolled bed sheet. At this time, the first winding roller 38 and the second winding roller 39 inside the left storage box 31 are unwound synchronously to achieve disinfection of the bed sheet. Replacement, after the next patient uses it, the two winding motors 36 on both sides of the storage box 31 at the left end of the rolled-up bed sheet are started synchronously, so that the first winding roller 38 and the second winding roller 39 wind the bed sheet to the left, and the first solenoid valve 44 and the second solenoid valve 47 at the left end are started, so that the disinfectant inside the liquid storage tank 41 is sprayed out through the first spray nozzle 45 and the second spray nozzle 48, and the rolled-up wide bed sheet 34 and the narrow bed sheet 35 are wiped by the first wiping cotton 46 and the second wiping cotton 49 to achieve the disinfection of the rolled-up bed sheet. At this time, the first winding roller 38 and the second winding roller 39 inside the right storage box 31 are unwound synchronously to achieve the replacement of the bed sheet, so that when the CT examination bed with a lower infection control standard is used, simple disinfection can be achieved between different patients;

[0061] When a CT examination bed with a high infection control standard is used, after the patient uses it, when changing the bed sheet, the two winding motors 36 on both sides of the storage box 31 at one end of the rolled bed sheet are started synchronously, so that the first winding roller 38 and the second winding roller 39 wind up the bed sheet. At this time, the first winding roller 38 and the second winding roller 39 inside the storage box 31 at the other end unwind synchronously to achieve the replacement of the bed sheet. Finally, the box cover 32 is opened by bolts, so that the wide bed sheet 34 and the narrow bed sheet 35 can be taken out and replaced.

[0062] When the patient lies flat on the top of the movable bed board 13, the first shielding member 21 is manually pulled to slide the main sliding frame 212 from the first sliding track 17 to the second sliding track 33 and move to the part that needs to be shielded, and the first electric telescopic rod 2113 is controlled to contract to make the first sliding cross frame 2114 slide on the first supporting longitudinal rod 2116. At this time, the first lead cloth 2115 will be affected by gravity, and the middle part will begin to sag and press on the patient's body. As the first electric telescopic rod 2113 contracts, the first lead cloth 2115 will be spread flat on the patient's body to shield the parts of the patient that do not need to be examined. The patient does not need to wear a lead suit, thereby improving the patient's examination efficiency. After the examination is completed, the first electric telescopic rod 2113 is extended again to make the first sliding cross frame 2114 move to both ends on the first supporting longitudinal rod 2116, and the first lead cloth 2115 is unfolded and hung;

[0063] Pressing the movable button 216 causes the spring bolt 217 to retract inside the connecting frame 215, and the spring bolt 217 is disengaged from the first supporting wheel 213. At this time, pulling the sliding main frame 212 causes the sliding frame 222 to slide on the top of the fixed sleeve 214, and the first fixed plate 211 and the second fixed plate 221 are unfolded. By contracting the second electric telescopic rod 227, the second sliding cross frame 228 is controlled to move, and the middle part of the second lead cloth 229 is drooped and laid on the patient's body, thereby increasing the range of covering the patient's body parts.

[0064] In addition, when the first shielding member 21 and the second shielding member 22 are unfolded, the spring button 2112 is pressed to disengage the spring button 2112 from the interior of the positioning hole 218, and the sliding main frame 212 is pulled again to slide the movable inner frame 219 inside the fixed sleeve 214, so that the first shielding member 21 and the second shielding member 22 are separated, thereby shielding both ends of the patient's examination area, so that the shielding device 2 can be freely adjusted according to the examination area;

[0065] After use, push the sliding main frame 212 toward the storage box 15, so that the movable inner frame 219 is retracted inside the fixed sleeve 214, and the spring button 2112 is engaged with the inside of the positioning hole 218, and continue to push the sliding main frame 212 to make the sliding frame 222 slide on the top of the fixed sleeve 214, completing the retraction of the first shielding member 21 and the second shielding member 22, and making the first shielding member 21 and the second shielding member 22 stay on the top of the storage box 15.
