Description

Technical Field

[0001] The invention relates to the technical field of CT examination protection, and in particular to a matching protection device for a CT examination bed. Background Art

[0002] CT is a medical imaging technology that uses precise X-ray beams and high-sensitivity detectors to scan the human body layer by layer, and uses a computer to process the scanned data to generate high-resolution images of the body's internal cross-sectional, coronal or sagittal planes.

[0003] A CT bed refers to a specific device used for CT scanning. Its main purpose is to support and position the patient to ensure clear and accurate images can be obtained during the scanning process.

[0004] During the existing CT examination process, sensitive parts of the patient such as the prostate need to be protected to reduce the impact of radiation on the patient. The lead suit needs to be worn by the patient when in use, and patients of different body shapes need to use adapted lead suits. Wearing a lead suit that is too large will affect the protective effect. At the same time, when the lead cloth is used to cover the patient, it may fall off as the scanning bed moves. When scanning the abdomen or pelvis, the patient needs to lie on his side. Some patients are in poor health and cannot lie on their side, so they need auxiliary support. Therefore, the present application provides a CT examination bed supporting protective device to meet the needs. Summary of the invention

[0051] like Figures 1 to 5As shown, an embodiment of the present invention provides a protective device for a CT examination bed, including a CT scanner 1, a scanning bed body 2 is fixedly connected to the CT scanner 1, the CT scanner 1 and the scanning bed body 2 are prior art, a lying plate structure 3 is located on the scanning bed body 2 and connected, the lying plate structure 3 is used to provide a lying position for a patient to be subjected to a CT examination, and is convenient for disassembly and disinfection, an adjustment structure 4 is located inside the lying plate structure 3 and connected, a winding structure 8 is connected inside the adjustment structure 4, a lead cloth 7 is installed on the winding structure 8, the adjustment structure 4 is used to provide an installation space for the lead cloth 7 and the winding structure 8, and medical staff can move the adjustment structure 4 to prevent the patient from lying flat. The lead cloth 7 is driven to move so that the lead cloth 7 moves and adapts to the position of the patient to be protected. The headrest structure 5 is located on the lying board structure 3 and is connected to the headrest structure 5. The headrest structure 5 is used to stabilize the patient's head and position the patient's head. When the patient needs to lie on his side for scanning, the headrest structure 5 assists in supporting the patient to lie on his side. When the patient undergoes a CT scan, the patient lies flat on the lying board structure 3 with the patient's head resting on the headrest structure 5. When the patient's sensitive parts need to be protected, the adjustment structure 4 is moved to move the lead cloth 7 on the adjustment structure 4 to the position of the patient to be protected, and the lead cloth 7 on the winding structure 8 is pulled to cover the patient's sensitive parts for protection.

[0052] like Figures 3 to 6As shown, the lying plate structure 3 includes a lying plate 31 clamped on the scanning bed body 2, the bottom of the lying plate 31 is convex, and is used to fit with the surface of the scanning bed body 2, and the top is flat, which is convenient for the patient to lie flat, and the lying plate 31 is an integrally formed structure by injection molding. The integrally formed lying plate 31 shortens the production cycle, reduces labor costs and material waste, and a through hollow groove 315 is opened on one side of the lying plate 31. The shape of the hollow groove 315 is consistent with that of the lying plate 31, and is used to provide an installation position for the adjustment structure 4, so that the adjustment structure 4 can move inside the hollow groove 315. Cover plates 33 are clamped at both ends of the lying plate 31 close to the hollow groove 315, and the cover plate 33 is detachable. When the lead cloth 7 and the winding structure 8 inside the adjustment structure 4 are damaged, the lead cloth 7 and the winding structure 8 can be repaired and replaced by removing the cover plate 33. A symmetrical adjustment slide groove 316 is provided inside the hollow groove 315. The adjustment slide groove 316 is used to provide a sliding track for the adjustment structure 4 and limit its position. Lead cloth first perforations 313 connected to the hollow groove 315 are provided on both sides of the lying plate 31. The lead cloth first perforations 313 are used to connect the hollow groove 315 with the outside, so that the adjustment structure 4 can be extended from the lead cloth first perforations 313 to the outside of the lying plate 31 when the adjustment structure 4 is installed inside. At the same time, it is convenient for the lead cloth 7 inside the adjustment structure 4 to be adjusted from the two lead cloth first perforations The through hole 313 is passed through, and a headrest groove 311 connected to the hollow groove 315 is provided on the upper surface of the lying plate 31. The headrest groove 311 is used to install the headrest structure 5 and provide a sliding track for the headrest structure 5. Two symmetrical sets of adapter grooves 312 are provided on both sides of the upper surface of the lying plate 31 near the headrest groove 311. The adapter groove 312 and the hidden self-adjusting structure 6 also include a card connection unit for the lying plate structure 3 to be connected to the scanning bed body 2. The card connection unit is used to detachably connect the lying plate 31 to the scanning bed body 2, so that the entire lying plate structure 3 is detachable for easy maintenance and replacement. The card connection unit includes a clamping plate 32 fixedly connected to both sides of the lying plate 31. The clamping plate 32 is an elastic structure. The inner concave side of the clamping plate 32 is opened A plurality of mutually symmetrical groups of jacks 314 are provided, and each group of jacks 314 is plugged with a locking elastic sheet 34, which is an elastic structure. The concave side of the locking elastic sheet 34 fits with one side of the scanning bed 2, and the outer sides of the two splints 32 are fixedly connected with corresponding mounting handles 321. The thickness of the splints 32 gradually changes from thin to thick from the middle to the two sides. Therefore, when the staff bends the mounting handles 321, the splints 32 can be pulled to deform outwards. When the splints 32 are deformed, the locking elastic sheet 34 installed on the inner side thereof is also deformed, and the locking elastic sheets 34 on the two splints 32 are clamped into the two sides of the scanning bed 2, so that the lying board 31 is clamped on the scanning bed 2.

[0053] like Figures 3 to 5 and Fig.14As shown, the side of the adapting groove 312 near the headrest groove 311 is connected with a self-adjusting structure 6, and the self-adjusting structure 6 includes a rotating plate 61 rotatably connected to the two ends of the adapting groove 312. The self-adjusting structure 6 is composed of two sets of mutually symmetrical rotating plates 61, and both ends of the rotating plate 61 are fixedly connected with a rotating shaft. The adapting groove 312 and the rotating plate 61 are rotatably connected through the rotating shaft. The inner side of the rotating plate 61 is provided with a plurality of storage grooves 611, and the storage grooves 611 and the elastic strips 612 are adapted to each other, so that the elastic strips 612 can be adjusted. The elastic strip 612 can be stored in the storage groove 611. The bottom end of the storage groove 611 is fixedly connected with an elastic strip 612. The elastic strip 612 and the rotating plate 61 form an angle of 60 degrees. The elastic strip 612 is an elastic structure. In the initial state, the rotating plate 61 will be supported by the elastic strip 612 and tilted 60 degrees on the adapting groove 312. When the patient lies on the lying plate 31, the patient's back will contact the rotating plate 61, thereby squeezing the rotating plate 61. The rotating plate 61 is squeezed by the patient's back. After the force is applied, it will rotate in the direction of the adapter groove 312, and compress the elastic strip 612 while rotating until the elastic strip 612 is squeezed into the storage groove 611, and the entire rotating plate 61 is hidden in the adapter groove 312. The side of the patient's back cannot provide sufficient pressure, so the entire rotating plate 61 will not be squeezed into the adapter groove 312. The rotating plate 61 will also squeeze the patient's back under the support of the elastic strip 612. When the patient's lying position is offset, the squeezing force of the rotating plates 61 on both sides on the patient's back is different. Due to the different squeezing forces on the patient's back, the patient will feel uncomfortable on the back, so he will move and adjust by himself until the body is in the central axis position of the lying board 31. At this time, the pressure on the back is consistent. The self-adjusting structure 6 can assist medical staff in adjusting the patient's lying position on the lying board 31, so that the patient can adjust independently and keep the body in the center of the lying board 31 to ensure the accuracy of the scanned image, while saving the time of medical staff in adjusting the patient's position and increasing the efficiency of CT examination.

[0054] like Figures 3 to 5 and Figures 15 to 19As shown, the headrest structure 5 includes three moving blocks 51 slidably connected to the headrest groove 311. The moving blocks 51 are of an "I"-shaped structure. The moving blocks 51 are stuck on the headrest groove 311 and can slide on the headrest groove 311. The moving blocks 51 can drive the headrest 52 and the support unit 53 fixed on the top thereof to move by sliding. Thus, the headrest 52 moves to adapt to patients of different heights. The tops of the three moving blocks 51 are respectively fixedly connected with a headrest 52 and two support units 53. 3. The top middle position of the headrest 52 is concave, which is used to adapt to the shape of the patient's head and provide support for the patient's head. The support unit 53 is used to assist in supporting the patient's body. At the same time, its initial state is consistent with the shape of the headrest 52. The support unit 53 includes a fixed pillow 531 fixedly connected to the top of the moving block 51, one side of the fixed pillow 531 is rotatably connected to the moving pillow 532, the bottom of the fixed pillow 531 is fixed to the moving block 51, one side of the fixed pillow 531 is hinged to the moving pillow 532, and both sides of the moving pillow 532 are open. An extension slot 536 is provided, and an extension slot 537 is provided on the surface of the extension slot 536 close to the movable pillow 532. An extension piece 535 is slidably connected in the extension slot 536. An extension block 533 and a limit block 534 are fixedly connected at both ends of the extension piece 535. The limit block 534 is used to prevent the entire extension piece 535 from being pulled out. The shape of the extension block 533 is consistent with the shape of the extension slot 537. The depth of the extension slot 536 is slightly less than the depth of the extension block 533, the limit block 534 and the extension piece 535. Therefore, when the extension piece 535 is fully inserted into the extension slot 536, a part of the extension block 533 will be retained outside the extension block 533, which is convenient for medical staff to pull out the extension piece 535. The shape of the extension slot 536 is consistent with the shape of the limit block 534. The extension slot 537 reduces the extension slot 536 so that the intersection of the extension slot 536 and the extension slot 537 is consistent with the shape of the extension piece 535, which is used to limit the limit block 534 to prevent the entire extension piece 535 from being pulled out.

[0055] When the patient needs to lie on his side for examination and cannot lie on his side, the patient lies on his side on the reclining board 31, moves the two supporting units 53 to the patient's waist and chest respectively, rotates the movable pillow 532 to make it fit with the surface of the fixed pillow 531, and then the curved surface at the bottom of the movable pillow 532 rotates to face the patient, so that the patient's chest and waist are supported by the curved surface of the movable pillow 532, and the patient is assisted to lie on his side, which is convenient for medical staff to perform CT examinations. When the patient is large in size, the curved surface of the movable pillow 532 is small, and the patient's comfort will be affected when supporting the patient's body. The expansion block 533 can be pulled to pull out the extension piece 535, and the contact area between the movable pillow 532 and the patient's body is increased by the extension piece 535, thereby increasing the patient's comfort.

[0057] like Figure 7 , Fig. 9 and Fig.10As shown, the winding structure 8 includes a first mounting plate 81 fixedly connected to the inner wall of one side of the lead cloth adjusting frame 41, the shape of the first mounting plate 81 is fitted with the bottom end of the lead cloth adjusting frame 41, the inner wall of the lead cloth adjusting frame 41 is fixedly connected to the side opposite to the first mounting plate 81 with a second mounting plate 82, the second mounting plate 82 is fitted with the top end of the lead cloth adjusting frame 41, and the two sides of the first mounting plate 81 are fixedly connected with a corresponding plurality of first mounting rods 811, and the top ends of every two corresponding first mounting rods 811 are fixedly connected with fixed rods 812, and the plurality of fixed rods 812 are all in At the same horizontal height, since the first mounting piece 81 is an arc-shaped piece, and each fixed rod 812 is at the same horizontal height, the length of the first mounting rod 811 gradually changes from long to short from the middle to the two ends, so that when the lead cloth 7 installed inside is stretched to the maximum length, the lead cloth 7 is in a straight state, and the lead cloth 7 is in contact with the outer wall of the fixed rod 812. The two sides of the second mounting piece 82 are fixedly connected with a corresponding number of second mounting rods 821, and the tops of every two corresponding second mounting rods 821 are slidably connected with a moving rod 822. The first mounting rods 811 and the second mounting rods 811 are connected to the fixed rods 812. The mounting rods 821 are arranged alternately with each other, and the distance between the top end of each second mounting rod 821 and the surface of the arc-shaped first mounting piece 81 is 3CM, which can effectively increase the length of the lead cloth 7 interlaced on the first mounting rod 811 and the second mounting rod 821, and also includes a sliding unit for sliding the movable rod 822 on the second mounting rod 821. The sliding unit is used to realize the sliding of the movable rod 822 on the second mounting rod 821. The sliding unit includes a sliding groove opened on one side of the second mounting rod 821, and the two ends of the sliding groove are fixedly connected with a sliding rod 823, and the sliding rod 823 is sleeved A return spring 824 and a slip ring 825 are provided, and the two ends of the return spring 824 are fixedly connected to the bottom end of the sliding groove and one side of the slip ring 825 respectively, and the outer wall of the slip ring 825 is fixedly connected to the end corresponding to the movable rod 822. When the movable rod 822 is subjected to extrusion force, the slip ring 825 fixed at both ends of the movable rod 822 will be driven to move, and the slip ring 825 compresses the return spring 824 on the sliding rod 823 to move. When the movable rod 822 loses pressure, the slip ring 825 returns to its initial position under the return elastic force of the return spring 824, thereby driving the movable rod 822 to move to its initial position.

[0058] like Figures 7 to 13As shown, one end of the lead cloth 7 passes through one of the first through-holes 313 of the lead cloth and penetrates the second through-hole 412 of the lead cloth connected thereto, and passes through the outer sides of the staggered fixed rods 812 and the movable rods 822 in sequence, until it passes through another second through-hole 412 of the lead cloth and the first through-hole 313 of the lead cloth connected thereto, and the two ends of the lead cloth 7 are respectively fixedly connected with the first plug-in strip 71 and the second plug-in strip 72, one side of the second plug-in strip 72 is fixedly connected with the embedding strip 721, the two ends of the first plug-in strip 71 are fixedly connected to the inner side of the moving handle 42, and the top of the first plug-in strip 71 is provided with an embedding groove 71 adapted to the embedding strip 721. 1. When the position to be protected of the patient needs to be protected by the lead cloth 7, the second plug-in strip 72 is pulled to pull the lead cloth 7 out of the winding structure 8, and the pulled-out lead cloth 7 covers the position to be protected of the patient until the embedding strip 721 is inserted into the embedding groove 711 on the first plug-in strip 71. Since the embedding strip 721 is a mushroom-shaped structure, when the embedding strip 721 is squeezed, the embedding strip 721 made of rubber material is deformed under the squeezing force of the notch of the embedding groove 711 until the top end of the embedding strip 721 is squeezed into the embedding groove 711, and then the embedding strip 721 recovers its deformation, thereby clamping the second plug-in strip 72 on the first plug-in strip 71.

[0059] The working principle of the technical solution provided by the present invention is as follows: the lying plate structure 3 is installed on the scanning bed 2. During installation, when the staff bends the installation handle 321, the clamping plate 32 can be pulled outward to deform. When the clamping plate 32 deforms, the deformation of the engaging elastic sheet 34 installed on the inner side thereof is driven to deform, and the engaging elastic sheets 34 on the two clamping plates 32 are inserted into the two sides of the scanning bed 2, thereby engaging the lying plate 31 on the scanning bed 2.

[0060] When a patient is subjected to a CT scan, the patient lies flat on the reclining board 31. When the patient's lying position is offset, the rotating plates 61 on both sides exert different squeezing forces on the patient's back. Due to the different squeezing forces on the patient's back, the patient's back will feel uncomfortable, so the patient will move and adjust by himself until the body is in the central axis position of the reclining board 31. At this time, the pressure on the back is consistent, and the two sides of the back feel consistent. The patient is in a comfortable state, and then the headrest structure 5 is moved to the position of the patient's head so that the patient's head is resting on the headrest structure 5.

[0061] When it is necessary to protect the patient's sensitive parts, the moving handle 42 on the moving adjustment structure 4 can be bent by the medical staff to drive the lead cloth adjustment frame 41 to slide in the hollow groove 315 until it moves to the patient's protection position, and the second plug-in strip 72 is pulled to pull the lead cloth 7 out of the winding structure 8. When pulling, the lead cloth 7 squeezes the moving rod 822. When the moving rod 822 is subjected to the squeezing force, it will drive the slip ring 825 fixed at both ends of the moving rod 822 to move. The slip ring 825 compresses the reset spring 824 on the slide rod 823 to move. When the moving rod 822 is in the compressed position, the lead cloth 7 is released until the pulled out lead cloth 7 covers the patient's protection position, until the embedded strip 721 is inserted into the embedded groove 711 on the first plug-in strip 71 for protection.

[0062] When the patient needs to lie on his side for examination and cannot lie on his side, the patient lies on his side on the reclining board 31, moves the two supporting units 53 to the patient's waist and chest respectively, rotates the movable pillow 532 to make it fit with the surface of the fixed pillow 531, and then the curved surface at the bottom of the movable pillow 532 rotates to face the patient, so that the patient's chest and waist are supported by the curved surface of the movable pillow 532, and the patient is assisted to lie on his side, which is convenient for medical staff to perform CT examinations. When the patient is large in size, the curved surface of the movable pillow 532 is small, and the patient's comfort will be affected when supporting the patient's body. The expansion block 533 can be pulled to pull out the extension piece 535, and the contact area between the movable pillow 532 and the patient's body is increased by the extension piece 535, thereby increasing the patient's comfort.
