Description

Thoracic closed drainage tube with negative pressure suction device

Technical Field

The utility model belongs to the technical field of the negative pressure drainage technique and specifically relates to a take thoracic cavity closed drainage tube of negative pressure suction device.

Background

1. The existing closed thoracic drainage tube has a thick general tube diameter and a good drainage effect on pneumothorax patients, but for pleural effusion patients, if the skin of the thick closed thoracic drainage tube needs to be cut by 1-2 cm, pleural effusion can seep from the cut part and even cause infection in the thoracic cavity;

2. secondly, in clinical work, an Arrow tube or a pigtail tube for deep venipuncture is usually selected, the Arrow tube drainage has the main problem that the diameter of a tube opening is small, and the tube opening can drain the pleural effusion at the initial stage of tube placement, but the pleural effusion can not be drained at the second day or the third day after clamping because the drainage liquid volume can not exceed 1000ml each day, and the two factors can be related to: firstly, a pleural effusion drainage port is blocked by visible components in pleural effusion; ② after pleural cavity reduces pleural effusion, the lung after reopening leads to the drainage tube in pleural cavity to buckle, leads to pleural effusion drainage failure. Compared with Arrow tubes, the pigtail type thoracic drainage tube has the advantages of being not easy to block and bend, but has the disadvantages that: the pleural cavity belongs to annular airtight structure, and the patient takes the half-sitting position or the position of lying to have a rest more, and pleural effusion is because of the action of gravity, and the collection is in the lower position of position to the poly, can lead to the difficult pleural effusion of drainage play lower position like this, if pleural effusion exists for a long time, then easily leads to adhesion, parcel to appear in the pleural cavity, the pleural bodiness even.

3. And thirdly, under the normal condition, the negative pressure environment is in the pleural cavity, but the balance of the normal negative pressure environment is broken after the drainage is performed, if a drainage bag with a negative pressure device is connected to the drainage tube outside the pleural cavity, the drainage bag can continuously drain the pleural water, the tube placing time of a patient can be greatly reduced, and the infection probability of the pleural cavity is reduced.

4. Finally, the thorax closed drainage tube that uses often in clinical work at present does not have more ideal fixing device, and at the in-process of placing, the condition that thorax closed drainage tube deviates from outside the pleural cavity occasionally takes place (thorax closed drainage tube is heavier at the weight of pleural cavity outside portion, and the possibility of inwards sliding in is extremely low), if can design the thorax closed drainage tube that the antiskid is taken off on traditional drainage tube basis, then the emergence of the above-mentioned condition that can significantly reduce.

SUMMERY OF THE UTILITY MODEL
