Example two
On the basis of the first embodiment, further:
referring to fig. 2, 3 and 4, a buffering mechanism for preventing a patient from sliding off is arranged on a bed body 2, the buffering mechanism comprises a connecting block 10 in limited sliding connection with the surface of the bed body 2, a sliding groove 11 is formed in the surface of a base 1, a sliding block 12 fixedly connected with the connecting block 10 is in limited sliding connection in the sliding groove 11, two limiting rods 13 penetrating through the sliding block 12 and in sliding connection with the sliding block 12 are fixedly connected with the inner wall of the sliding groove 11, springs 14 for buffering the patient from sliding off are sleeved on the outer contours of the two limiting rods 13, and two ends of each spring 14 respectively abut against the inner wall of the sliding groove 11 and the sliding block 12.
Through being provided with the buffer gear that prevents the direct landing of patient on the bed body 2, prevent to slide fast at the in-process of bed body 2 slope, when the bed body 2 slope certain angle, make patient's sole and slider 12 contact, along with the patient continues to slide along the surface of bed body 2, can make the spring 14 that offsets with slider 12 on the gag lever post 13 compressed, the patient overcomes spring 14 elasticity and slides along the surface of bed body 2 this moment, thereby realize buffering the patient's landing through spring 14, thereby realize the protection to the patient, prevent that the patient from being directly by the roll-off at bed body 2.
Referring to fig. 4 and 5, an auxiliary mechanism is disposed on the bed 2, the auxiliary mechanism includes grooves 15 formed on two sides of the bed 2, the inner walls of the grooves 15 are penetrated and rotatably connected with a rotation shaft 16, the rotation shaft 16 is penetrated and fixedly connected with a support frame 17 for supporting armpits and arms of a patient, and grips 18 held by the patient are spaced on the inner walls of the support frame 17.
When the patient slides slowly along the surface of the bed body 2, ninety degrees of rotation is performed through the rotation shaft 16, and the power content of the rotation shaft 16 is disclosed in the following, so that the support frame 17 horizontally arranged and the bed body 2 are vertically arranged, and the armpits of the patient are supported, so that the patient can hold the grip 18 by both hands at the same time, the balance of the patient on the inclined bed body 2 is maintained, the patient is prevented from being directly washed out, and meanwhile, the patient can hold the grip 18 by both hands to assist in rising from the bed body 2.
Referring to fig. 4, 5, 6 and 7, a second mounting groove 19 is formed in the back of the bed body 2, two symmetrical L-shaped rods 20 fixedly connected with two sides of the slider 12 are in limited sliding connection in the second mounting groove 19, one end, far away from the slider 12, of each L-shaped rod 20 is fixedly connected with a sliding block 21 for driving the rotating shaft 16 to rotate, a sliding groove 22 is formed in the outer contour, close to the surface of the sliding block 21, of the rotating shaft 16, and a sliding rod 23 sliding with the sliding groove 22 is fixedly connected to the surface of the sliding block 21.
When the connecting block 10 contacts with the sole of the patient and the inclination angle of the bed body 2 is larger, the pressure applied by the patient to the connecting block 10 is larger and larger, the connecting block 10 is pushed to move against the elastic force of the spring 14, at the moment, the sliding block 12 fixedly connected with the connecting block 10 moves, so that the L-shaped rod 20 fixedly connected with the sliding block 12 pulls the sliding block 21 fixedly connected with the sliding block 21 to move away from the groove 15, the sliding rod 23 slidably connected with the sliding block 21 slides in the sliding groove 22 formed on the outer contour of the rotating shaft 16 through the movement of the sliding block 21, as shown in fig. 6, when the sliding block 21 slides in the sliding groove 22, the sliding rod 23 slides from the position A to the position B to the position C through the spiral sliding groove which is one-fourth, the rotating shaft 16 rapidly rotates to the position ninety degrees with the bed body 2, the sliding groove which is axially arranged from the position B to the position C is the sliding groove which is axially arranged with the rotating shaft 16, the rotating shaft 16 keeps the stable state which is ninety degrees with the bed body 2, the sliding rod 23 slides from the position B to the position C, the sliding groove 16 is arranged in the sliding groove, the sliding groove is arranged on the sliding body, the sliding body 16 is arranged on the sliding body, the sliding body 16 is supported by the sliding body, and the sliding body 2 is supported by the patient, and the patient can slide from the hand body 2 to the hand body 2.
Referring to fig. 2, the supporting frame 17 is disposed in a right trapezoid shape, and the width of the supporting frame 17 near the bed end is larger than the width near the bed head.
When the rotation axis 16 rotates to be ninety degrees states with the bed body 2, along with the bed body 2 continuing to be lifted, inclination is bigger and bigger, patient armpits slide along the outer wall of the supporting frame 17, meanwhile, the supporting frame 17 is in a right trapezoid shape, the width of the supporting frame 17 close to the bed tail is larger than the width of the supporting frame close to the bed head, so that the outer wall of the supporting frame 17, which is contacted with the patient, is inclined away from the bed body 2, and when the patient armpits slide along the outer wall of the supporting frame 17, the patient can be finally far away from the bed body 2, and 21 lifting is further assisted.
Example III
On the basis of the second embodiment, further:
referring to fig. 2, 3 and 5, an airbag 24 is disposed on the outer contour of the support frame 17 contacting with the patient, two inflators 25 for inflating the two airbags 24 are fixedly mounted in the second mounting groove 19, the air outlet ends of the inflators 25 are connected with a connecting pipe 26 extending toward the airbag 24 in a penetrating manner, one end of the connecting pipe 26 away from the inflators 25 is connected with the airbag 24 in a penetrating manner, and the connecting pipe 26 is a hose.
When the inflator 25 inflates the air bag 24 on the support frame 17 through the connecting pipe 26, specific inflation is disclosed in the following, the contact part between the patient and the air bag 24 is more comfortable, when the patient is prevented from sliding down on the bed body 2, the arm or the armpit of the patient is directly rubbed or offset with the contact part, the skin of the patient is damaged, the hose is used as a hose through the connecting pipe 26, and the hose has certain toughness, so that the connection part is disconnected when the rotating shaft 16 rotates and the air bag 24 is pulled.
Referring to fig. 2, a toothed plate one 27 is fixedly connected to opposite sides of the two L-shaped rods 20, a gear 28 meshed with the toothed plate one 27 is fixedly connected to one side, close to the toothed plate one 27, of the second mounting groove 19 in a rotating manner, a toothed plate two 29 meshed with the gear 28 is connected to the second mounting groove 19 in a limiting sliding manner, and a connecting column 30 for inflating the air bag 24 is fixedly connected to the end, close to the inflator pump 25, of the toothed plate two 29.
By the above-mentioned inclination along with the bed body 2 is bigger and bigger, can make the patient to the pressure that the connecting block 10 applyed and promote the connecting block 10 and remove, thereby make the L shape pole 20 that is connected with slider 12 fixed move, can make the pinion rack 27 that is connected with L shape pole 20 fixed move, respectively with pinion rack 27 and pinion rack two 29 through gear 28 meshing, and be located the both sides of gear 28, when pinion rack 27 keeps the same direction slider 12 direction motion with L shape pole 20, this moment pinion rack two 29 moves to the direction of connecting pipe 26, through pinion rack two 29 end fixed connection to the spliced pole 30 that inflates the gasbag 24, spliced pole 30 moves to the connecting pipe 26 direction and promotes the piston that is located the inflator 25, compress the gasbag 24 through connecting pipe 26 with the piston in the inflator 25, thereby realize the inflation to gasbag 24.
