Embodiment 1

[0030] Such as Figure 1-5 As shown, a closed chest drainage device includes a saline bucket 1 and a drainage bottle 2. The drainage bottle 2 is a hollow and closed cavity, the saline bucket 1 is an open mouth, and the top of the drainage bottle 2 is provided There is a drainage tube interface 3 and a water-sealing tube interface 4. The drainage bottle 2 is inserted into the saline bucket 1, and a hollow cavity structure of saline is formed between the bottom of the drainage bottle 2 and the cavity bottom of the saline bucket 1 The water-sealing tube 5 communicates the drainage bottle 2 with the inner cavity of the saline chamber through the water-sealing tube interface 4, and the free end of the water-sealing tube 5 extends below the surface of the physiological saline in the saline chamber. Since there is a gap between the water-sealing tank and the water-sealing pipe, there will be air circulation in this gap. The drainage bottle of the chest cavity closed drainage device o...

Embodiment 2

[0041] The same parts in this embodiment and Embodiment 1 will not be repeated, and the differences are as follows.

[0042] Such as Image 6 As shown, the drainage bottle 2 in this embodiment is not provided with a water-sealing tube clamping groove, but a plurality of vertical convex grooves 12 are provided on the side wall of the salt water bucket 1, and the water-sealing tube 5 passes through The convex groove 12 extends into the salt water chamber, and the cross section of the convex groove 12 is greater than or not less than the cross section of the water seal pipe 5. A number of exhaust gas corresponding to the convex groove 12 are provided on the side wall of the salt water bucket 1 For the liquid inlet 11, the convex groove 12 penetrates the upper and lower surfaces of the drainage bottle 2.

[0043] A number of vertical convex grooves 12 are provided on the side wall of the salt water bucket 1, and the water seal pipe 5 extends through the convex groove 12 into the salt w...

Abstract

The invention discloses a closed thoracic drainage device which comprises a saline bucket and a drainage bottle. The drainage bottle is a hollow closed cavity. The saline bucket is an open cavity. The top of the drainage bottle is provided with a drainage pipe connector and a water seal pipe connector. The drainage bottle is inserted into the saline bucket, and a saline chamber of a hollow cavity structure is formed between the bottom of the drainage bottle and the bottom of the cavity of the saline bucket. A water seal pipe communicates the drainage bottle with the inner cavity of the saline chamber through the water seal pipe connector, and the free end of the water seal pipe extends below the liquid face of normal saline in the saline chamber. The drainage bottle of the closed thoracic drainage device is inserted into the saline bucket to form an integral structure, and the situation that two independent bottle bodies in a traditional drainage device are inconvenient to use is avoided.

Description

Technical field [0001] The invention relates to a medical device, in particular to a closed chest drainage device. Background technique [0002] In the medical field, when gas and fluid accumulate in the chest cavity of a patient, it may cause lung collapse, decreased respiratory function, and even life-threatening. For such patients, closed chest drainage is usually required. The most commonly used drainage device in clinical medicine is the closed thoracic drainage bottle, which is composed of two bottles arranged side by side, including drainage cavity, saline cavity, catheter, water-sealed tube and trachea. The catheter is connected to the chest tube. The effusion and gas in the patient's pleural cavity enter the drainage cavity through the chest tube and catheter. The effusion is stored in the drainage cavity, and the overflowing gas enters the saline bottle from the water-sealed tube and then is discharged from the air outlet tube. Although this kind of closed thoracic dra...
