Description

Technical Field

[0032] Embodiment 2

[0033] As Figure 1 - Figure 4 shown, the embodiment of the present invention provides a respiration monitoring device for radiotherapy, including a reclining board 1. A support leg 2 is fixedly connected to the lower side of the reclining board 1. Slide grooves 8 are opened on the upper sides of the front and rear ends of the reclining board 1. A slide block 9 is slidably connected to the inside of the slide groove 8. A fastening unit 7 is arranged on the upper side of the slide block 9. A respiration monitor 6 is arranged on the upper side of the reclining board 1. Elastic bands 13 are fixedly connected to both the front and rear sides of the respiration monitor 6. A bottom plate 10 is fixedly connected to the lower side of the slide block 9. A moving block 11 is fixedly connected to the lower side of the bottom plate 10. Two bottom blocks 4 are fixedly connected to the lower side of the reclining board 1. A screw 12 is rotatably connected between the two bottom blocks 4. A motor 1 5 is fixedly connected to the outside of the bottom block 4. The screw 12 is threadedly connected to the moving block 11. The output end of the motor 1 5 is fixedly connected to the outer end of the screw 12. When monitoring the respiration of a patient, first, the patient lies on the reclining board 1, and then the motor 1 5 is started. The motor 1 5 drives the screw 12 to rotate. The screw 12 drives the moving block 11 to move. The moving block 11 drives the bottom plate 10 to move. The bottom plate 10 drives the slide block 9 to move left and right. The slide block 9 drives the fastening box 701 to move. Under the action of the elastic band 13, the respiration monitor 6 is controlled left and right, facilitating the respiration monitor 6 to move to the chest of the patient, and then the respiration monitor 6 is installed more stably through the fastening unit 7.

[0034] The fastening unit 7 includes a fastening box 701, which is fixedly connected to the upper side of the rear slider 9. A storage groove 715 is formed inside the fastening box 701. A rotating rod 716 is rotatably connected inside the storage groove 715. A winding roller 717 is fixedly connected to the outer side of the rotating rod 716. The winding roller 717 is fixedly connected to the elastic band 13. A second motor 702 is fixedly connected to the outer side of the fastening box 701. A fixed frame 703 is fixedly connected to the upper side of the front slider 9. An insertion box 705 is arranged inside the fixed frame 703. The insertion box 705 is fixedly connected to the elastic band 13. Limiting grooves 706 are formed in the left and right inner walls of the fixed frame 703. Insertion rods 707 are arranged inside the limiting grooves 706. One end of the insertion rod 707 is located inside the insertion box 705 and is provided with a rectangular groove 708. An inclined plate 709 is rotatably connected inside the rectangular groove 708. The outer sides of the upper ends of the inclined plates 709 on the left and right sides are rotatably connected to a rotating block 710. A lifting block 712 is fixedly connected to the upper side of the rotating block 710. A pull rod 713 is fixedly connected to the upper side of the lifting block 712. A pull plate 714 is fixedly connected to the upper end of the pull rod 713. A spring 711 is fixedly connected between the lifting block 712 and the insertion box 705. Before monitoring, first insert the insertion box 705 into the fixed frame 703 (at this time, pull the pull plate 714). Pulling the pull plate 714 drives the pull rod 713 to move. The pull rod 713 drives the lifting block 712 to rise. The lifting block 712 drives the inclined plate 709 to incline. Since the inclined plates 709 on both sides are symmetrically distributed, the inclined plate 709 drives the insertion rods 707 to approach each other. Under the action of the elastic force of the spring 711, when the insertion box 705 is inserted into the fixed frame 703 and then the hand is released, the insertion rods 707 on both sides are separated. The insertion rods 707 are inserted into the limiting grooves 706, so that the insertion box 705 is limited, and the two sides of the respiratory monitor 6 are preliminarily limited. Then start the second motor 702. The second motor 702 drives the rotating rod 716 to rotate. The rotating rod 716 drives the winding roller 717 to rotate, so that the winding roller 717 drives the elastic band 13 to tighten, making the respiratory monitor 6 closely attached to the patient's chest, facilitating subsequent monitoring.

[0035] Embodiment 2

[0036] As Figure 5 - Figure 7As shown in the figure, mounting boxes 704 are fixedly connected to both the left and right sides of the respiratory monitor 6. Rotating shafts 728 are rotatably connected to the outer sides of the front and rear ends of the mounting boxes 704. Stable clamping blocks 729 are fixedly connected to the outer ends of the front and rear rotating shafts 728. A pressure sensor 730 is fixedly connected to the lower side of the stable clamping block 729. A contact plate 731 is fixedly connected to the lower end of the pressure sensor 730. One end of the rotating shaft 728 is located inside the mounting box 704 and is fixedly connected to a gear 718. A moving groove 720 and a stable groove 726 are formed inside the mounting box 704. Connecting blocks 721 are slidably connected to the inner sides of the front and rear ends of the moving groove 720. A toothed plate 719 is fixedly connected to the upper side of the connecting block 721. An inclined plate two 722 is rotatably connected to the outer side of the toothed plate 719. Side blocks 723 are rotatably connected to the outer sides of the upper ends of the front and rear inclined plates two 722. A control block 724 is fixedly connected to the upper side of the side block 723. An electric push rod 725 is fixedly connected between the control block 724 and the mounting box 704. The toothed plate 719 is meshed with the gear 718. A stable block 727 is slidably connected to the inside of the stable groove 726. The stable block 727 is fixedly connected to the control block 724. Before monitoring, control the electric push rod 725 to drive the control block 724 to move upward. The control block 724 drives the inclined plate two 722 to rotate. Since the two inclined plates two 722 are symmetrically distributed, the inclined plate two 722 drives the toothed plate 719 to move. The front and rear toothed plates 719 approach each other. Since the toothed plate 719 is meshed with the gear 718, the gear 718 rotates. The gear 718 drives the rotating shaft 728 to rotate. The rotating shaft 728 drives the stable clamping block 729 to rotate, so that the front and rear stable clamping blocks 729 rotate in the direction close to the patient, and the stable clamping block 729 limits the respiratory monitor 6, increasing the stability during monitoring.

[0037] A respiratory monitoring method for radiotherapy includes the following steps:

[0038] S1. The patient lies on the lying board 1, and then starts the motor one 5 to control the movement of the respiratory monitor 6 so that the respiratory monitor 6 moves to the patient's chest.

[0039] S2. Pull the pull plate 714, insert the plug box 705 into the fixed frame 703, release the hand so that one end of the elastic band 13 is limited, and then start the motor two 702 to make the respiratory monitor 6 closely adhere to the patient's chest.

[0040] S3. Control the electric push rod 725 to drive the front and rear fastening clamping blocks 729 to rotate and contact the patient, limit the respiratory monitor 6, and then turn on the respiratory monitor 6 to monitor the patient.
