5. Preparation for use

Important The preparation for use of these devices must be performed by qualified personnel to ensure the specific suitability of the product for the user and the correct working order of all parts and accessories, as well as to provide clear instructions to the user.

5.1. Preliminary check

5.1.1. (STAND-UP ETM)

The STAND-UP ETM is shipped with the seat and backrest partially raised. Before using the device for the first time, it is recommended to perform a preliminary test as follows, including the raising and lowering of the seat without the user in position.

  • Press the ON/OFF button 1 to turn on the device (see 4.5, “Joystick use (STAND-UP ETM)”).

  • Check that the battery charge is at least over 60%, indicated by at least one green LED 2 being illuminated. If not, it is still possible to complete the tests, but it is recommended to perform a charging cycle for optimal use.

  • Press the ACTUATOR/TRACTION SELECTION button 3 (a yellow 1 will light up to indicate the selected ACTUATOR, and the green LEDs for traction will turn off).

  • Use the joystick to fully raise the seat to the vertical position, then lower it completely to the transfer position.

  • Press the ACTUATOR/TRACTION SELECTION button again, and this time the yellow 1 will turn off and the green LEDs for traction will light up.

  • Check the operation of the SLOW 4 and FAST 7 buttons (tortoise and hare symbols), and a green LED will move from minimum to maximum speed. It is advisable to start with a 30% setting to become familiar with the manoeuvring space and required clearance of the aid.

Schema delle parti di Happy Standing

  • The two levers located under the seat, at the level of the footplate, enable or disable the motor operation. By turning both levers forcefully outward (a tactile click can be felt), the motors are engaged and can be operated by the joystick.

  • By turning the levers inward by about half a turn (with force, feeling a tactile click at the end), the motors are inhibited, and the STAND-UP can be manually moved by an assistant.
Note The two levers are snap-back. This means that pulling them back and rotating them allows the handle’s position to be adjusted. This is convenient for when the previous position conflicts with other devices or the floor, but it can be confusing at first. Simply remember that rotating the levers inward stops the motors, while rotating them outward activates them.

The used batteries are 2 x 12VDC 17Ah. The batteries can remain constantly connected to the charger without any risk of overcharging.

If, for any reason, the batteries do not allow the descent operation, refer to Chapter 14, Manual activation of the actuator in case of emergency (STAND-UP ST, STAND-UP EE, STAND-UP ETM)

Unresolved directive in ../lingue/en/modelli/stabilizzatori/12_setup_stabilizzatori.adoc - include::../../../modelli/happy_standing/adjustments.adoc[leveloffset=+1]

13.2. STAND-UP ST, STAND-UP EE, STAND-UP ETM

Important For correct use and proper adjustment, consult a therapist or other qualified personnel
Note Especially at the beginning, qualified personnel’s assistance is essential to avoid any inconvenience. In some cases, upright positioning can create excessive load on the lower limbs and may require a personalized rehabilitation program. Especially at the beginning, the user may experience balance problems due to the unusual upright position. In this case, qualified personnel’s assistance is required for a rehabilitation program.
Important For safety reasons, always perform every ascent and descent operation with the parking brakes engaged.

13.2.1. Adjustment of the heel-stops

Before using for the first time, it is advisable to proceed with the adjustment of the heel-stops as follows:

  • Remove the fastening screws A.

  • Move the heel-stops to the desired position.

  • Reposition and secure the screws A.

STAND-UP Heel-stops

Velcro foot straps can be installed upon request.

13.2.2. Adjustment of the knee supports

Important The positioning of the knee supports should be done under the supervision of a therapist or qualified personnel. For safety reasons, any adjustments should be made with the parking brakes engaged. Perfect the adjustment with the user seated and proceed as follows:

HEIGHT ADJUSTMENT:

  • Loosen the two fastening screws B.

  • Position the supports at the desired height.

  • Tighten the two screws B again.

STAND-UP knee height adjustment

DEPTH ADJUSTMENT:

  • Loosen the two fastening screws C.

  • Position the supports at the desired width.

  • Tighten the two screws C again.

WIDTH ADJUSTMENT:

  • Loosen the two fastening screws D.

  • Position the supports at the desired depth.

  • Tighten the two screws D again.

STAND-UP knee depth adjustment

13.2.3. Adjustment of the chest support

If necessary, proceed with the adjustment of the chest support as follows:

HEIGHT ADJUSTMENT:

  • Loosen the two safety nuts E.

  • Loosen the positioning butterfly F.

  • Position the chest support G at the desired height.

  • Tighten the positioning butterfly F.

  • Secure the two safety nuts E.

STAND-UP Chest-support

DEPTH ADJUSTMENT:

  • Loosen the two fastening nuts H.

  • Position the chest support I at the desired depth.

  • Tighten the two nuts H again.

STAND-UP Chest-support

Now proceed with the user’s first elevation under the supervision of a therapist or qualified personnel, ensuring that:

  • The parking brakes are engaged.

  • The feet are stable and properly secured by the heel-stops.

  • The knee supports are in the correct position.

Note The actuator is active in elevation as long as the WRC1 button is pressed. Therefore, the control of the ascent must be operated manually by the person managing the control keyboard. The actuator is equipped with two limit switches (see 7.1, “Limit switches”). One determines the horizontal position (seated) and automatically stops the movement even if the WRC2 button continues to be pressed. The other controls the vertical position (upright), but in most cases, it is necessary to manually stop the elevation releasing the pressure from the WRC1 button before reaching the limit to avoid excessive pressure of the body on the chest support.

13.2.4. Adjustment of the table

The table should be adjusted with the user in an upright position; therefore, it is necessary to execute the user’s first elevation. This should be done under the supervision of a therapist or qualified personnel, ensuring that:

  • The feet are stable and properly secured by the heel-stops.

  • The knee supports are in the correct position.

Note The actuator is activated and controlled via a joystick. During the ascent, it is advisable to constantly monitor the user’s balance.
Important The actuator is equipped with two limit switches (see 7.1, “Limit switches”). One determines the horizontal position (seated), while the other controls the vertical position (upright). In most cases, it is necessary to halt the elevation before reaching the limit switch to prevent excessive pressure on the chest against the chest support.

The table’s position is subjective and depends on how the user intends to use it. Once the person is in an upright position, you can proceed with the table adjustment as follows:

  • Loosen the two fastening screws J.

  • Position the table at the desired location.

  • Tighten the two screws J again.

STAND-UP Heel-stops

14. Manual activation of the actuator in case of emergency (STAND-UP ST, STAND-UP EE, STAND-UP ETM)

Important When performing this operation, be extremely careful never to completely detach the actuator from the joint.

In case the user is in an upright position and due to a malfunction of the control board, the descent operation is not possible, it becomes necessary to manually intervene to return the user to a seated position. In this case, proceed as follows:

  • Remove the locking screw by unscrewing it with a 5 mm Allen key.

  • Unscrew the actuator by gripping the upper black tube and turning counterclockwise, (as described below) supporting the seat with one hand.

STAND-UP Heel-stops

Note To facilitate manual operation on the actuator, you can partially support the seat to avoid putting the entire load on the axis of the actuator to be turned. Exercise extreme caution and avoid excessive lifting that could dislodge the joint from the actuator and prevent supporting the entire user’s weight.
Important When performing the EMERGENCY operation, be mindful to avoid crushing fingers and hands between the mechanical arms.
Important Support the seat only by the back horizontal bar (indicated in the previous pictures) and avoid the vertical bars!
