Examples

The shifting machine is a movable apparatus for shifting users (such as patients or old people) with body mobility deficiency, so that the users can be conveniently shifted in the scenes of bed-to-wheelchair, wheelchair-to-toilet, wheelchair-to-bathing equipment and the like, and the burden of nursing staff is reduced. The armpit support 200 is arranged on the existing shifting machine to serve as a human body supporting device, the armpit support 200 is connected to the armpit of a user, and the user can easily slide or fall off the armpit support 200 in the using process.

Figures 1 and 2 show the displacement machine of this embodiment with a personal support device that prevents the user from slipping.

The shifter comprises a frame 100, the lower end of the frame 100 is connected with a chassis which can be stepped, the upper end of the frame 100 is connected with a supporting arm 110, and the human body supporting device is arranged at the tail end of the supporting arm 110.

The human body supporting device comprises a U-shaped armpit support 200 and a protective belt 300, wherein the armpit support 200 is arranged at the tail end of the supporting arm 110, and the protective belt 300 is connected with the armpit support 200.

U-shaped armpit holds in the palm 200 and forms the backward cavity of opening, user's chest back sets up in the cavity, its antethorax is towards the cavity, its armpit puts up on two support arms of U-shaped armpit support 200, the both ends of protecting band 300 are connected at the armpit and are held in the palm 200 both ends, in order to walk around user's back and seal the opening of cavity, thereby the cavity inner wall and the protecting band 300 that the armpit held in the palm 200 form the closed loop, the chest back position of user trunk is located this closed loop, the user can not follow the armpit and hold in the palm the slippage on 200, protecting band 300 supports at user's back, can prevent that user's upper part from leaning on backward and falling, of course, under the cavity restriction, the user also can not topple over forward or fall to the side about or fall to the side, solve the easy problem of falling or.

The support arm 110 may be further hinged to the frame 100, so that the support arm 110 can rotate, a pitch push rod 120 is disposed between the frame 100 and the support arm 110, one end of the pitch push rod 120 is hinged to the frame 100, and the other end is hinged to the support arm 110. The pitching push rod 120 stretches and retracts to push the supporting arm 110 to rotate, so that the armpit support 200 at the tail end of the supporting arm 110 generates height change, and the height of the armpit support 200 is adjusted to be convenient for being suitable for users with different heights. When the pitching push rod 120 stops stretching, the rack 100, the supporting arm 110 and the pitching push rod 120 form a triangular supporting structure, so that the internal stress of the shifter is stable, and the stability of the shifter is improved.

In addition, under the supporting and fixing of the pitching push rod 120 and the supporting arm 110, the angle of the armpit support 200 is in a forward tilting state, the stress at the concave cavity is relatively increased, the stress of the protective belt 300 is relatively reduced, and the function of further preventing the user from bending backwards and falling is achieved.

Further, the armpit support 200 can be telescopically arranged on the supporting arm 110, so that the position of the armpit support 200 in the front-back direction of the displacement machine can be adjusted conveniently, and users with different body types can use the displacement machine conveniently. As shown in fig. 1, a telescopic push rod 111 is provided on the support arm 110, and an armpit 200 is mounted at the end of the telescopic push rod 111. When the telescopic push rod 111 extends out, the armpit support 200 is far away from the support arm 110 and the machine frame 100; when the telescopic rod 111 is retracted, the armpit 200 is close to the support arm 110 and the frame 100.

Because the user's both legs are inconvenient, under the fixed condition of the position of running-board 131, can appear stepping on empty problem, and the leg opens and shuts the angle uncomfortable and also can appear both legs unstability and lead to the removal process not smooth, even the safety risk that drags the line or falls appears. To solve this problem, the aforementioned treadable chassis is configured as two support legs 130 hinged at the lower end of the frame 100, and each support leg 130 is provided with a foot pedal 131. The position of the pedal 131 can be adjusted by rotating the support leg 130, so that the position of the pedal 131 is adjusted to a position where a user can step on the pedal comfortably, and the risk of instability is reduced.

In addition, as seen in fig. 1, the rollers of the displacer include two rollers mounted at the lower end of the frame 100 and two rollers at the rear ends of the two support legs 130, that is, the displacer is supported on the ground by the two rollers at the lower end of the frame 100 and the two rollers at the rear ends of the support legs 130. When two supporting legs 130 expand relatively, two gyro wheel intervals grow of rear end, and the support area increase that four gyro wheels formed is equivalent to the change and has increased the chassis area mutually, makes the aversion machine more stable, is difficult to the slope and leads to equipment to overturn or the user to fall down.

When moving the user onto the displacement machine, the following operations may be performed:

the armpit of the user is erected on the armpit support 200, so that the chest and the back of the user are positioned in the concave cavity of the armpit support 200 sealed by the protective belt 300. The two support legs 130 are closed to bring the two foot pedals 131 close together, and the caregiver places the user's legs on the left and right foot pedals 131. The pedal 131 is close to the pedal, so that the pedal can be conveniently stepped on, and the function of preventing stepping empty is achieved. Then the two support legs 130 are properly opened and the position of the pedal 131 is adjusted to make the pedal 131 in a comfortable position for the user.

Further, at least one end of the protective band 300 is detachably connected to the armpit 200 to facilitate the movement of the user into the cavity. In the process that a nursing person moves a user to the shifting machine, one end of the protective belt 300 can be detached to open the opening of the cavity, so that the two support arms of the armpit support 200 penetrate under the armpit to support the user, then the movable end of the protective belt 300 is wound around the back of the user and is connected to the armpit support 200 to be fixed, and the protective belt 300 seals the cavity and supports the back of the user. The length of the guard band 300 is adjustable to accommodate users of different sizes.

In order to further reduce the risk of the user slipping off the armpit 200 backward when the user has been put on the armpit 200 while the guard band 300 is temporarily not mounted during the movement of the user to the shifter by the caregiver, the left and right ends of the armpit 200 are set to be bent upward to form the escape prevention portion 210. The anti-slip part 210 extends from the armpit of the user to the shoulder to be supported behind the shoulder of the user, and the nursing staff is not easy to slip after taking off the hand, and can vacate the hands to fix the protection belt 300. In addition, the separation prevention part 210 and the guard band 300 together provide a supporting force on the back of the user during the movement of the shifter to prevent the user from bending backward.
