Description

Closed chest drainage device

technical field

The utility model relates to the technical field of medical supplies, in particular to a closed chest drainage device. the

Background technique

Chest closed drainage bottle is a commonly used medical device, and it is a device for draining pleural fluid and air out of the body. The chest drainage device of the prior art is directly connected to the patient and the drainage bottle by the drainage connecting tube. Therefore, in the drainage process after empyema, hemothorax and chest surgery, pus and blood clots often occur to block the drainage port, causing the drainage tube to lose its capacity. Drainage effect. Closed thoracic drainage tubes cannot be flushed like abdominal drainage tubes, and can only be squeezed to remove blockages. However, the tube wall of chest cavity drainage tubes is relatively hard, and the extrusion pressure is small, so the effect is not good, and it is difficult to discharge blockages; In addition, the existing closed chest drainage device must clamp the drainage tube with a hemostat when the patient is moving and transferring to prevent the backflow of drainage fluid and gas. Frequent clamping will cause damage to the drainage tube and lead to failure of chest drainage .           

Contents of the invention

To sum up, the purpose of this utility model is to provide a closed chest drainage device. the

The purpose of this utility model is achieved by the following technologies:

A pleural irrigation and drainage device is composed of an upper drainage catheter, a three-way valve, a lower drainage catheter and a drainage bottle. The three-way valve is provided with a rotary valve; one end of the upper drainage catheter is connected to the chest drainage puncture catheter through the connector II, and the other One end is connected to the first port of the three-way valve through the connector I; the upper end of the drainage catheter is connected to the second port of the three-way valve, and the lower end is soaked in the drainage bottle; the upper part of the drainage bottle is provided with an air filter plug, and the lower part is provided with a drain mouth.

Air vents are arranged in the above-mentioned air filter plug, and air filter paper is attached to the lower end. the

The above-mentioned drainage bottle is provided with a scale. the

The above-mentioned liquid discharge port and the tee of the three-way valve are closed by a heparin cap. the

Advantages and beneficial effects of the utility model:

1. The utility model can attract the drainage of the upper catheter through the three-way valve upwards, and can flush the drainage of the lower catheter downward to keep the thoracic closed drainage device unobstructed, and at the same time maintain the drainage of the upper catheter during the flushing and suction process Always under negative pressure.

2. The utility model can close or open the upper drainage catheter and the lower drainage catheter by changing the direction of the three-way valve, so that when the patient is transported or the body position is changed, the damage to the drainage tube caused by clamping with the hemostat can be avoided. the

3. The utility model can maintain the airtightness and sterility of the whole thoracic closed drainage device through the pinhole plug of the standby air filter paper arranged at the air opening of the drainage bottle. the

4. The utility model releases the drainage liquid and infuses sterilized distilled water through the liquid discharge port under the drainage bottle, so as to prevent the pollution caused by frequently opening the drainage bottle cork to discharge the liquid and perfuse the sterilized distilled water, and also saves the workload. the

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described:

As shown in Figures 1 and 2, a chest irrigation drainage device is composed of an upper drainage catheter 1, a three-way valve 3, a lower drainage catheter 4, and a drainage bottle 5. The three-way valve 3 is provided with a rotary valve 9; One end of catheter 1 is connected to the chest drainage puncture catheter through connector II8, and the other end is connected to the first port of three-way valve 3 through connector I2; the upper end of catheter 4 is connected to the second port of three-way valve 3, and the lower end is soaked in the drainage bottle. 5; the upper part of the drainage bottle 5 is provided with an air filter plug 6, and the lower part is provided with a liquid discharge port 7; the air filter plug 6 has air holes, and the lower end is attached with air filter paper; the drainage bottle 5 is provided with a scale; The port 7 and the tee of the three-way valve 3 are closed by a heparin cap 10 .

Example

After successful thoracentesis and drainage, the upper drainage catheter 1 is connected to the puncture catheter for thoracic drainage, the three-way valve 3 is connected to the upper drainage catheter 1 through the connector I2, and the lower drainage catheter 4 passes through the stopper of the drainage bottle 5 to the drainage bottle 5 At the bottom, the drainage bottle 5 is closed with a cork, and an air filter plug 6 is arranged on the bottle stopper; air filter paper is attached to the inner surface of the air filter plug 6; the liquid discharge port 7 at the side end of the bottom of the drainage bottle 5 is closed with a heparin cap. the

During operation, if there is drainage material in the upper drainage catheter 1, by rotating the rotary valve 9 of the three-way valve 3, the outer convex end thereof communicates with the upper drainage catheter 1. Connect the three-way of the three-way valve 3 with an empty needle, and suction the fluid with negative pressure to keep it unobstructed. the

If there is drainage material in the drainage catheter 4, by rotating the rotary valve 9 of the three-way valve 3, its outer convex end communicates with the drainage catheter 4. At this time, the drainage upper catheter 1 is closed, and the medical staff passes through the empty needle for sterile injection. Connect the three-way of the three-way valve 3, flush the drainage with positive pressure to keep it unobstructed. the

If the patient's body position changes, getting out of bed, and carrying, the rotary valve 9 of the three-way valve 3 can be rotated to keep the drainage upper catheter 1 in a closed state to prevent air from flowing back into the chest cavity. the

When the liquid in the drainage bottle 5 needs to be replaced, the liquid can be discharged through the discharge port 7, and then the sterilized distilled water is infused into the drainage bottle 5 through the discharge port 7 to complete the replacement of the liquid in the drainage bottle 5. the
