detailed description

The present invention will be further described below in conjunction with the accompanying drawings.

As shown in Figure 1, a patient transfer device that can be used as a hospital bed includes a load-bearing unit, a lifting unit and a support unit, and the load-bearing unit includes two vertically symmetrical vertical supports fixed on the base 1 beside the bed 2 and the horizontal bar 3 fixedly connected to the top; the load-bearing unit is an aluminum alloy bracket, which is firm and reliable, and has a good appearance.

The lifting unit includes a lifting group and a translation group, and the lifting group includes a fixed pulley 7 respectively connected to a fixed pulley 7 by a lifting rope 8 at both ends of a horizontally arranged lifting crossbar 4, and the fixed pulley 7 is fixed on the horizontal crossbar. 3; the translation group is a translation pulley 5 arranged on the lifting crossbar 4, and the translation pulley 5 translates and slides along the translation track on the lifting crossbar 4, and the translation pulley 5 and the translation track form a Small assembly of translation group. The lifting unit raises the patient to satisfy the transfer; using the translation pulley 5, the translation of the patient can be realized smoothly and easily.

Lifting rope 8 passes through described fixed pulley 7, and the other end is connected with self-locking hand-operated device 6, and described self-locking hand-operated device 6 is fixedly arranged on the bottom of described vertical support 2; Set along the vertical support 2. As shown in Figure 4, the self-locking hand crank device 6 is fixed on the lower part of one of the vertical supports 2, and the upper part of the vertical support 2 is fixedly provided with No. 3 fixed pulley 7-3; Respectively connect No. 1 fixed pulley 7-1 and No. 2 fixed pulley 7-2 by lifting rope 8, then merge together and pass through described No. 3 fixed pulley 7-3, and then wind with described self-locking hand-cranking device 6 Roller 601 is connected. Self-locking hand-operated device 6 controls the hoisting rope 8 at both ends to go up and down simultaneously, and keeps the hoisting cross bar 4 balanced all the time. Because of the soft cloth carrying the patient, the lifting distance is always equal, so as long as the lengths of the lifting ropes at both ends are adjusted during manufacture, the balance of the lifting crossbar can be guaranteed. .

As shown in Figures 2 and 3, the self-locking hand-operated device 6 uses a combination of a worm 606 and a helical gear 605, which can reduce the lifting force to 1/20 of the patient's weight, and realize easy operation by one person. The self-locking hand-operated device 6 adopts a combination of a worm 606 and a helical gear 605, and the winding roller 601 and the helical gear 605 are fixed on the rotating shaft 602 in turn, and the rotating shaft 602 between the two is provided with a jack, and the jack is provided with There is a safety pin 603 matched therewith, and the safety pin 603 uses a spring 604 to push into the socket. The spring 604 withstands the safety pin 603. Specifically, the upper end of the spring 604 withstands the cover plate on the upper part of the self-locking hand crank device 6, and the lower end of the spring 604 withstands the lower end of the safety pin 603. In a natural state, the safety pin 603 is pressed by the spring force 604. It is inserted into the hole of the rotating shaft 602, so that the rotating shaft 602 cannot rotate and is in a locked state. When an upward external force pulls the upper end of the safety pin 603, and the pulling force is greater than the force of the spring 604, the safety pin 603 can be disengaged. The rotating shaft 602 is rotated so that the rotating shaft 602 can rotate. The safety pin 603 supported by the spring 604 is always inserted in the hole of the rotating shaft 602 when there is no external force; the safety pin 603 must be pulled up with one hand, and the other hand can turn the handle 607 to realize the lifting of the patient. This guarantee guarantees the safety of patients to the greatest extent.

The lower end of the translation pulley 5 is connected to the bracket unit arranged horizontally. The bracket unit is composed of two aluminum alloy fixing tubes 12 and a shaped soft cloth 11 fixedly connected therebetween. Two groups of hooks 10 are arranged symmetrically on the fixing tubes 12 on both sides. The translation pulley 5 is fixedly connected with the hook 10 through the steel wire 9, and hangs the soft cloth bed steadily at four points to realize lifting. Through the bracket unit composed of aluminum alloy fixing tube 12, shaped soft cloth 11, neck protection pad 13, and side protection pads 14, the patient's body position will not change during the transfer process, and the patient is protected from secondary damage to the greatest extent. harm.

Example

When the patient was admitted to the hospital, the soft cloth 11 for setting the shape was just laid on the first hospital bed or the mobile bed that the patient lay on, and followed the patient in the following pre-rehabilitation time. When the patient needs to be transferred, the target bed is first placed on the side of the bed currently used by the patient, and the aluminum alloy bracket load-bearing unit is installed on the bed. The two vertical supports 2 are respectively on the outside of the two beds, and the two beds are surrounded on the inside. Horizontal cross bar 3 is placed in the position directly above two beds. Use the hook 10 to hook the four hanging points around the shaped soft cloth 11, turn the handle 607 of the self-locking hand-operated device 6, raise the patient, and slowly drag it to the top of the target bed, then unlock the self-locking hand-operated device 6, slowly Put down the patient. During this process, the patient only contacts with the shaped soft cloth 11 all the time, avoiding the secondary injury caused by moving.

A method for a patient transfer device that can be used as a hospital bed, comprising the following steps:

1) Ascent: Turn the handle 607 of the self-locking hand-operated device 6, start the self-locking hand-operated device 6, pull back the lifting rope 8 connected thereto to move downward, and the lifting rope 8 passes through the fixed The pulley 7, the other end of which acts on the elevating bar 4, pulls it up, and the elevating bar 4 drives the support unit to rise from the original bed; stop the self-locking hand device 6;

2) Translation: slide the translation pulley 5 to other positions of the elevating bar 4, and correspondingly, the support unit can be translated to the required horizontal position, that is, the target bed;

3) Falling: start the self-locking hand-cranking device 6 in reverse, release the lifting rope 8 outward, and the lifting bar 4 and the bracket unit pull the lifting rope 8 down to the required height together , that is, to the target bed.

The above is only a preferred embodiment of the present invention, it should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, some improvements and modifications can also be made, and these improvements and modifications are also possible. It should be regarded as the protection scope of the present invention.
