The main pull rope 9 is conveyed to the lower side from the upper end of the guide plate 2, the first springs 4 can be arranged in a plurality of numbers and are positioned on two sides of the main pull rope 9, meanwhile, arc-shaped guide grooves can be formed in the upper wall and the lower wall of the inner cavity of the guide plate 2, and the first springs 4 are arranged in the guide grooves to avoid the front-back sliding of the first springs 4. Here, the retraction and inversion of the flap 5 are synchronized, which increases the space above the patient's face.

Still including setting up the operating device who is used for conveniently inhaling the phlegm and trampling the mechanism of being connected with total stay cord 9 at the front end of check curtain 6, trampling the mechanism and installing subaerially around the head of a bed side, and trampling the mechanism and can step on through medical personnel and press pulling total stay cord 9 in order to realize that baffle 5 accomodate left and anticlockwise upset. The operating mechanism is convenient for sputum suction operation, when sputum is normally sucked, the baffle 6 is not taken away to avoid sputum spraying, and the baffle 5 is turned over to facilitate other treatment and nursing. The pedal mechanism utilizes the gravity of medical personnel to drive the main pull rope 9, so that the baffle 5 is contracted and overturned at the same time.

The operating mechanism comprises an operating opening 10 arranged at the front end of the stop curtain 6, a movable curtain 11 for shielding downwards is fixed on the operating opening 10, and the lower end of the movable curtain 11 is bent outwards in an arc shape to form a lifting part 12 convenient for being held by hands. The opening part 12 extends out of the operation opening 10, therefore, sputum cannot be stained with, the hand pinch is convenient, the check curtain 6 can adopt a soft silica gel layer, the cleaning and the disinfection are convenient, and meanwhile, the toughness is realized. The opening part 12 is provided with a hanging hole, and the baffle 5 is provided with a first hook ring 13 which is convenient for hanging the hanging hole. Facilitating the fixing of the raised curtain 6.

The treading mechanism comprises two dorsad bottom plates 26 which are right-angled and fixed at the lower end of the supporting rod 1, the two bottom plates 26 are fixed together, the free ends of the two bottom plates 26 extend out of the sickbed and then are fixed with bases 21 which can be clamped into the ground, the ground is clamped for reducing the height, the bases 21 are in a square shell shape with an upper end opening, pedals 22 which can move up and down and are in square adaptation with a shell shape with a lower opening are inserted in the bases 21, the top wall of the inner cavity of each pedal 22 is connected with the bottom wall of the inner cavity of each base 21 through a plurality of second springs 23, a rotating shaft 24 is rotatably connected between the upper sides of the front and rear walls of the inner cavity of each base 21, the two rotating shafts 24 oppositely penetrate through the bases 21 and then are connected with winding wheels 25, the middle parts of the winding wheels 25 are provided with antiskid winding grooves, the winding grooves are fixed with branch pull ropes 27, the branch pull ropes 27 are fixed with a main pull rope 9 after extending along the bottom plates, a plurality of guide rings for guiding the branch pull ropes 27 are fixed on the bottom plates 26, the fixed point of the branch pulling rope 27 is close to the supporting rod 1, and the fixed point can not be close to the bending part of the bottom plate 26, so that the branch pulling rope 27 on the opposite side is prevented from being pulled. The same guide ring that is fixed with the direction to total stay cord 9 on the bracing piece 1 guarantees that total stay cord 9 can be along the vertical downwards of bracing piece 1, and the opening 28 that corresponds with pivot 24 is all seted up to the front and back end of footboard 22, and opening 28 supports pivot 24 when avoiding footboard 22 to move down, still including setting up the drive mechanism between pivot 24 and footboard 21, and transport mechanism can drive pivot 24 when moving down and rotate the coiling in order to realize coiling wheel 25. The transmission mechanism has a transmission ratio, that is, the linear speed of the winding wheel 25 is multiple of the descending speed of the pedal 22, so that the small-distance movement of the pedal 22 can generate a larger pulling distance, thereby the height of the pedal 22 is lower, and the pedal is not easy to have a sharp feeling when being stepped on, and the characteristic that the weight of medical staff or family members is far more than the pulling force is fully utilized. The transmission mechanism comprises a tooth groove 29 formed in the circumferential direction of the middle of the rotating shaft 24, a rack 30 which is downward and meshed with the tooth groove 29 is fixed on the top wall of an inner cavity of the pedal 21, the rack 30 is located on one side of the rotating shaft 24, the diameter of the winding wheel 25 is multiple times of that of the rotating shaft 24 and can be 3-10 times, and the transmission mechanism can be specifically determined according to the diameter of the winding wheel 25 and the telescopic distance of the baffle 5.
