Three Balls Incentive Spirometer

Basic Product Definition

The Three Balls Incentive Spirometer is a handheld respiratory rehabilitation device that meets medical-grade standards. It is primarily designed to guide users in performing scientific slow deep breathing exercises to strengthen respiratory muscles, improve pulmonary ventilation, and increase vital capacity.Equipped with a visual three-ball flow feedback system, it quantifies and tracks the breathing training process. It is a standard device worldwide for perioperative pulmonary care, rehabilitation of chronic respiratory diseases, and home-based lung health management.Unlike traditional single-mode spirometers, its core innovation lies in its dual-mode inhalation and exhalation integrated design, allowing one device to fully support both inspiratory and expiratory training.

Core Design & Functional Highlights

1. Dual-Mode Bidirectional Training System

This device is one of the few on the market that supports both inhalation and exhalation training. No additional accessories are required; users only need to adjust the device orientation to switch modes:

Upright position: standard inhalation training mode

Inverted position: automatic switch to exhalation training mode

A single device meets the full-cycle respiratory training needs of patients for preoperative preparation, postoperative rehabilitation, and chronic disease management, greatly reducing procurement costs for institutions and usage costs for individuals.

2. Three-Ball Graded Visual Flow Calibration System

The device features a three-color ball grading design, where different colored balls correspond to different inhalation flow and volume levels. During training, the balls rise and fall synchronously with breathing airflow, providing instant and intuitive visual feedback.This helps users precisely control breathing rhythm and intensity, and enables medical staff to quickly evaluate patients’ respiratory recovery and develop personalized rehabilitation plans.The chamber is made of highly transparent medical-grade material with precise calibration scales, allowing direct reading of training volume data to ensure standardized and traceable training.

3. Medical-Grade Precision Structure & Safety Configuration

The entire device is made of medical-grade PVC, ABS, PP, and PE materials, with biocompatibility meeting medical device standards. It is odorless, free of harmful substances, and safe for long-term clinical and home use.The body adopts an integrated seamless sealing process to prevent air leakage during training, ensuring stable airflow pressure and accurate training data.It is equipped with soft, skin-friendly medical-grade inhalation tubing and a sealed mouthpiece. The mouthpiece fits the human oral structure for a tight seal to avoid air leakage, and the flexible tubing adapts to training in multiple body positions.

Technical Specifications

Clinical & Home Application Value

With its dual-mode design and medical-grade quality, the Three Balls Incentive Spirometer is widely applicable in clinical settings, professional rehabilitation, and home care. Its core values include:

Perioperative Prevention of Pulmonary Complications

For patients undergoing thoracic, abdominal, orthopedic, or neurosurgical procedures who require long-term bed rest, preoperative training and regular postoperative use effectively maintain lung ventilation, promote airway secretion clearance, and significantly reduce the risk of common postoperative pulmonary complications such as atelectasis and hypostatic pneumonia, shortening the hospital stay and rehabilitation period.

Rehabilitation Management for Chronic Respiratory Diseases

For patients with chronic obstructive pulmonary disease (COPD), bronchial asthma, pulmonary fibrosis, and other chronic respiratory conditions, regular bidirectional breathing training strengthens respiratory muscles such as the diaphragm, improves pulmonary ventilation efficiency, relieves shortness of breath and wheezing, and enhances daily activity and quality of life.

Pulmonary Care for Long-Term Bedridden Patients

For elderly, paralyzed, or mobility-impaired individuals, daily use maintains lung activity and airway patency, preventing lung infections and respiratory decline caused by insufficient long-term ventilation.

Lung Function Exercise for Healthy Individuals

Suitable for smokers, people exposed to dust, vocal performers, and athletes for daily lung function training to improve vital capacity and breathing control.

Standardized Full-Process Operation Guide

To ensure training effectiveness and safety, strictly follow the operating procedures below.

Preparation

Sit upright or in a semi-recumbent position. Place the device steadily, connect the inhalation tubing, main unit, and mouthpiece, and inspect the device for damage or loose connections.

Inhalation Training Mode (Device Upright)

1.Place the mouthpiece fully in the mouth and seal it tightly with lips to prevent air leakage.

2.Inhale slowly and deeply through the mouthpiece to lift the balls steadily.

3.After reaching maximum comfortable inhalation, hold breath for 3–5 seconds to keep the balls elevated and fully expand alveoli.

4.Release the mouthpiece and exhale evenly through the nose, allowing the balls to fall naturally. Rest for 5–10 seconds to complete one cycle.

Exhalation Training Mode (Device Inverted)

1.Invert the entire device and secure the tubing and mouthpiece. Maintain a comfortable position.

2.Inhale deeply through the nose until the lungs are fully inflated.

3.Seal the mouthpiece with lips and blow slowly and evenly into the device to lift all three balls sequentially.

4.After full exhalation, release the mouthpiece and exhale through the nose. Rest briefly to complete one cycle.

Recommended Training Frequency

Training frequency should follow clinical medical guidance. The general recommendation is approximately 10 cycles per hour while awake, with intensity increased gradually to avoid discomfort.

Safety Instructions & Daily Maintenance

Safety Precautions

● Stop training immediately and rest if dizziness, chest tightness, or shortness of breath occurs. Seek medical attention if symptoms persist.

● This device is for single-patient use only. Do not share to avoid cross-infection.

● Train gradually. Do not hold breath excessively to raise the balls. Patients with cardiac insufficiency or severe lung disease must follow medical advice strictly.

● Discontinue use and replace the device if the chamber is cracked, poorly sealed, or the tubing is damaged.

Daily Maintenance

● Clean the mouthpiece and inhalation tubing with medical alcohol or neutral detergent after each use. Air-dry and store in a dry, clean area away from direct sunlight.

● Avoid dropping or squeezing the main unit to prevent chamber damage that may affect scale accuracy and sealing.

● Thoroughly clean and air-dry the device before long-term storage, then seal it to prevent moisture and contamination.
