Negative pressure drainage device type II is a medical device mainly used in surgical procedures, trauma care, and wound management. It helps to remove wound exudate and promote wound healing through negative pressure suction. The following is a detailed introduction to the negative pressure drainage device type II:

---

### **1.  Product Overview**

Negative pressure drainage device type II is a portable and reusable negative pressure drainage device, usually consisting of a drainage bottle, connecting tube, negative pressure pump, and dressing. It helps to remove wound exudate, reduce the risk of infection, promote granulation tissue growth, and accelerate wound healing by creating a continuous negative pressure environment.

### **2.  Main components**

-Drainage bottle: used to collect wound exudate, usually with a scale for easy observation of drainage volume.

-Connecting tube: Connect the wound dressing and drainage bottle to ensure smooth drainage of the fluid.

-Negative pressure pump: a manual or electric pump used to create a negative pressure environment.

-* * Dressing * *: It covers the wound surface and is usually made of porous foam or gauze to help distribute negative pressure evenly.

---

### **3.  Working principle**

The negative pressure drainage device type II generates negative pressure through a negative pressure pump, and sucks the wound exudate into the drainage bottle through a connecting tube. Meanwhile, negative pressure environment can promote blood circulation in the surrounding tissues of the wound, stimulate granulation tissue growth, and accelerate wound healing.

### **4.  Main purpose**

-Surgical procedure: Used for postoperative wound drainage to prevent fluid accumulation and infection.

-Trauma care: Used to treat acute or chronic wounds, such as burns, ulcers, pressure sores, etc.

-Infection control: By removing exudate and necrotic tissue, the risk of infection is reduced.

-* * Promote healing * *: Promote granulation tissue growth and wound closure through negative pressure stimulation.

---

### **5.  Product Features**

-* * Portability * *: Small size, light weight, convenient for patients to carry.

-* * Reusable * *: The drainage bottle and negative pressure pump can be cleaned, disinfected, and reused.

-Adjustable Negative Pressure: Adjust the negative pressure intensity according to the wound condition to ensure better results.

-Safe and reliable: Made of medical grade materials, non-toxic and harmless, in compliance with medical standards.

### **6.  Usage method**

1. * * Preparation * *: Clean the wound and choose a suitable dressing to cover it.

2. * * Connection device * *: Connect one end of the connection tube to the dressing and the other end to the drainage bottle.

3. * * Start negative pressure * *: Use a negative pressure pump to generate negative pressure and ensure the drainage system is sealed.

4. * * Observation Record * *: Regularly observe the drainage volume and wound condition, and replace drainage bottles and dressings in a timely manner.

5. * * End of use * *: When the drainage volume decreases or the wound heals, stop using and clean the equipment.

### **7.  Precautions**

-Before use, check if the equipment is in good condition to ensure there are no leaks or blockages.

-Regularly replace dressings and drainage bottles to avoid infection.

-Adjust the negative pressure intensity according to the doctor's advice to avoid tissue damage caused by excessive negative pressure.

-If any abnormalities occur during use (such as pain, infection, etc.), stop using immediately and consult a doctor.

---

### **8.  Applicable population**

-Postoperative patients

-Patients with chronic wounds (such as diabetes foot and pressure sore)

-Acute trauma patients (such as burns, lacerations)

-Patients who require long-term wound care

---

### **10.  Advantages**

-Accelerate wound healing and reduce hospitalization time.

-Reduce the risk of infection and improve nursing effectiveness.

-Easy to operate, suitable for home care and hospital use.
