Non-invasive ventilator housing | Housing accessory project for household respiratory assistive medical equipment

1. Project background

The client is a high-tech enterprise specializing in medical devices, developing and producing home non-invasive ventilators for home respiratory assistance therapy for individuals with sleep-related breathing disorders. The equipment requires long-term continuous operation. The interior of the shell integrates a fan, pressure sensing components, and an airflow channel. The shell not only needs to support the components but also requires regular cleaning and disinfection. The original shell air duct structure is unreasonable, resulting in relatively high airflow noise. The consistency of shell dimensions is poor, leading to low assembly efficiency. The material is not resistant to disinfection and is prone to aging after long-term use.

II. Core pain points of customers

1. The precision of the air duct molding inside the shell is insufficient, leading to turbulent airflow and high noise levels;

2. The shell has a large volume, poor consistency in injection molding dimensions, and uneven assembly gaps between the upper and lower shells;

3. Ordinary plastic is not resistant to medical disinfectants, and long-term wiping can cause the shell to age and discolor;

4. The tolerance of the mounting and positioning column of the shell is unstable, making it difficult to assemble the fan and sensor;

5. The entire machine generates heat during continuous operation, and the heat resistance of the shell material is insufficient.

III. Customized Solutions

1. Select low-leaching medical modified plastics to meet the safety requirements for household medical materials;

2. The shell mold is integrally formed to optimize the internal air duct structure, ensuring smooth airflow and reducing wind noise;

3. Strictly control the injection molding tolerance of the large shell, optimize the structure of the positioning column, and facilitate the assembly of fans and sensors;

4. Formula optimization, resistant to alcohol and medical disinfectant wiping, not prone to aging and discoloration;

5. The shell is reinforced with ribs to enhance its overall rigidity, and it also possesses good heat resistance, making it suitable for long-term continuous operation;

6. Complete reliability tests such as high and low temperature tests, aging tests, etc.

IV. Project Achievements

• The air duct is precisely shaped, ensuring smooth airflow through the equipment and effectively reducing operational noise;

• The shell size is stable, the assembly gaps are uniform, and the assembly efficiency is improved;

• The shell can withstand long-term disinfection and wiping without obvious aging or discoloration;

• Stably protect the fan and pressure sensing components to ensure long-term continuous operation of the ventilator;

• The ventilator casing has completed full-machine verification and is ready for bulk delivery.
