What technical requirements must a universal patient bed in a healthcare facility in Vietnam meet?

Hello, Lawnet would like to answer as follows:

1. What technical requirements must a universal patient bed in a healthcare facility in Vietnam meet?

According to TCVN 6790:2001, the technical requirements for a four-section, three-crank universal patient bed with wheels and without wheels, used in healthcare facilities, are as follows:

(1) General requirements

The bed must have a sturdy and durable structure capable of bearing a load of at least 400 kg. The bed frame and bed slats must be able to bear a load of 100 kg (normal load).

The bed must maintain stability and not vibrate in any position.

The welding joints must be smooth and without defects or cracks, according to TCVN 1691:1975.

All parts of the bed must have rounded edges or chamfered edges, with three smooth surfaces.

Stainless steel parts must have a polished surface with a roughness value of Ra ≤ 0.63 µm.

Carbon steel parts must be coated with a layer of electrostatic powder paint with a thickness of 0.15 ÷ 0.25 mm or nickel-chrome plating with a thickness of 10 ÷ 13 µm.

The bed must withstand a hot and humid environment without damage (peeling paint, rust).

The bed must be able to be disassembled into separate components (head frame, main frame, side rails, armrests, curtain posts, and wheels) for convenient storage and transportation.

After assembly, the bed must be symmetrical, without any tilting or warping. The bed surface in the initial position must be taut and flat. The maximum deviation on the entire bed surface must not exceed 10 mm.

(2) Requirements for major components

The mattress surface must be taut, flat, water-repellent, and not absorb blood or other fluids. The mattress must be easy to clean and not retain an odor after cleaning.

The lifting screws for the bed slats must be smooth. The bed slats must move smoothly without jamming, slipping, shaking, or producing noise.

The range of adjustment for the bed slats is as follows:

The backrest slats can be adjusted to a maximum height difference of 240 mm from the initial position.

The headrest slats can be adjusted to an angle of up to 200 degrees from the initial plane, corresponding to the maximum adjustment position of the backrest slats.

The seat slats can be adjusted to a maximum height difference of 200 mm from the initial position.

The legrest slats can be adjusted to an angle of up to 700 degrees from the initial plane, corresponding to the maximum adjustment position of the seat slats.

The four wheels must rotate smoothly around their axes. When the brakes are applied to two wheels, the bed must be firmly fixed.

The patient record holder must be securely attached to the lower head frame and be symmetrical. The record holder must securely hold and easily remove paper, with the ability to hold 1 to 15 layers of 0.1 mm thick paper without wrinkling.

2. What are some testing methods for a universal patient bed before it is put into use in Vietnam?

According to TCVN 6790:2001, the testing methods for a universal patient bed are as follows:

(1) Before testing, the bed should be assembled according to the manufacturer's instructions.

(2) Check the basic dimensions and shape of the bed using visual inspection and common measuring tools.

(3) Load-bearing capacity test.

Place the bed on a flat surface. Apply a load of 400 kg, evenly distributed over the entire bed surface, for 60 seconds. Apply a load of 100 kg, evenly distributed on any bed slat, for 60 seconds.

The result is considered satisfactory if: the components are not damaged. The bed frame and slats are not deformed. The welding joints are not peeled. The connections are not loose. The maximum deviation of the slats at any position does not exceed 20 mm.

(4) Mechanical strength test.

- Test the strength of the bed surface.

- Test the impact resistance.

(5) Position stability test.

Place the bed on a 100-degree inclined surface compared to the horizontal plane. Block the four legs with a 40-mm-high stopper. Apply a load of 100 kg on the bed edge near the inclined end.

(6) Test the operation of the screws and bed slats.

Test the operation of the screws and slats by applying a force of 500 N to the center of gravity of each slat (backrest, seat, and legrest). The torque required for adjustment should not exceed 70 N at any adjustment position.

(7) Brake test.

Apply a load of 100 kg, evenly distributed on the bed. Place the bed on a 100-degree slope. Apply the brakes to the two wheels.

The result is considered satisfactory if: the bed does not slide.

(8) Rust resistance test

Test the rust resistance under the following conditions: place the bed in a test chamber with a temperature of 27 ± 2°C and a humidity of 90% for 16 consecutive hours. Then, spray ion-free water (soft water) at a temperature of 40°C for 6 days.

The result is considered satisfactory if: the bed surfaces do not show signs of rust. The plated details do not exhibit peeling or blistering.
