Description

Multimodal shifter

The present invention relates to a shifting machine, and more particularly to a multimodal shifting machine that facilitates the transfer of a patient with poor mobility to a wheelchair, a bed, a toilet, and a car seat.

Generally, there are many tools for moving patients who have poor mobility, such as patients or people with disabilities. The most common ones are wheelchairs. However, in terms of nursing care, patients with poor general mobility often need to go to and from beds, bathroom equipment, and car seats. Therefore, although the wheelchair is suitable as a tool for moving patients, when the patient moves between the wheelchair and the car seat, the bed, and the bathroom, it is usually carried by the caregiver. Because the general care workers are mostly women, This way of moving patients is indeed a great burden on the physical care staff.

In order to change the above missing, there is a hanging type shifting machine as shown in FIG. 1 , which mainly comprises: a rectangular bottom frame 11 , a plurality of casters 12 mounted under the bottom frame 11 , and a a strut 13 inclined from the bottom frame 11 to the upper rear, a pair of handles 14 fixedly mounted on the strut 13 and adjacent thereto, a suspension arm 15 pivotally mounted above the strut 13 and extending forward, a top A hydraulic cylinder 16 supported between the strut 13 and the suspension arm 15, and a hammock 17 suspended from the front lower side of the suspension arm 15.

When in use, the patient is moved into the hammock 17, and then the hydraulic cylinder 16 is controlled to move the suspension end 151 of the suspension arm 15 upward, so that the patient can be lifted, and the caregiver who assists the handling only needs to hold the handle 14 , you can push the entire lift to move.

Although the conventional hanging type shifting machine can hang the patient with poor mobility, it is necessary to move the patient with difficulty in movement to the soft hammock 17 and then remove the patient from the hammock 17 after reaching the destination. The use mode is not only troublesome when moving, high risk, and long shift operation time, and it is also easy to cause discomfort in use for a patient who is not very comfortable with the body. On the other hand, the conventional hanging type shifting machine can only select the hanging method to move the patient, and its function is not only monotonous, but also can not select a safe and comfortable moving mode according to the needs of different patients, so the design is not ideal.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a multi-modal lift that reduces the burden on a caregiver while moving a patient while enhancing the safety and comfort of the patient while moving.

The multimodal shifting machine of the present invention comprises: a moving mechanism, a skeleton unit mounted on the moving mechanism, a lifting mechanism movable up and down along the skeleton unit, a connecting mechanism mounted on the lifting mechanism, and an alternative A load bearing module mounted on the link mechanism and a support module replaceably mounted on the skeleton unit. Wherein the skeleton unit comprises a nursing push frame and an adjusting main shaft having a screw portion, and the lifting mechanism comprises a lifting main seat, a lifting unit synchronously lifting and lowering with the lifting main seat, and a driving unit for driving the lifting unit The driving unit may be configured to allow the patient to ride, stand or lie on the basis of the need, and the connecting mechanism installs the carrying module on the lifting main seat in a detachable manner, and the supporting module is Removably mounted on the adjustment spindle, and depending on the need to take a seat belt, armrest, table, protection or sling to assist the patient's upper body positioning, or to assist in fixing the carrier module.

The beneficial effect of the invention is that: the carrying module and the supporting module can be matched according to the needs of the patient, and the shifting machine can easily approach the patient and easily move the patient, so the design of the shifting machine of the invention can not only It reduces the burden on the caregiver when moving the patient, and also improves the comfort and safety of the patient when they are moved.
