abdominal drainage tube

Abstract

The invention discloses a novel abdominal cavity drainage tube. The novel abdominal cavity drainage tube comprises a guiding tube made from a plastic material. The bottom end and the top end of the drainage tube are open ends, a pair of circular balloons which are arranged up and down along the axial direction of the guiding tube fixedly sleeve the outer contour surface of the guiding tube, communicating tubes communicating with the cavities of the circular balloons are fixed on the two circular balloons, and latex air bags with exhaust valves are fixed at the other ends of the communicating tubes. When the novel abdominal cavity drainage tube is used for draining hydrops in the abdominal cavity, the novel abdominal cavity drainage tube plays the roles of preventing blockage, leakage, slippage and being free of fixation, and is worth being popularized.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a peritoneal drainage tube used for drainage of peritoneal effusion. Background technique [0002] The purpose of surgical drainage is to guide the pus, blood, and exudate accumulated between human tissues or body cavities to the outside of the body to treat or prevent further deterioration of the disease. [0003] Most of the current drainage tubes are single hollow tubes. After one end is put into the abdominal cavity, the place where the drainage tube passes through the skin needs to be ligated and fixed on the skin with sutures; Loosening or falling off causes the drainage tube to come out, especially when the patient is active, the drainage tube is more likely to come out, and the peritoneal effusion cannot be drained out of the body, requiring re-intubation, which will increase the risk of infection and is extremely detrimental to the recovery of the patient.

[0003] Most of the current drainage tubes are single hollow tubes. After one end is put into the abdominal cavity, the place where the drainage tube passes through the skin needs to be ligated and fixed on the skin with sutures; Loosening or falling off causes the drainage tube to come out, especially when the patient is active, the drainage tube is more likely to come out, and the peritoneal effusion cannot be drained out of the body, requiring re-intubation, which will increase the risk of infection and is extremely detrimental to the recovery of the patient. Inconvenience to the work of medical staff

[0004] Chinese invention patent CN 105013066 A discloses a double-balloon drainage tube used in the abdominal cavity or thoracic cavity. Drainage cavity, the head of the tube body is provided with a drainage port; the tube body is provided with a scale mark for displaying the length from the head to the tail; the flushing tube is set in the tube body drainage cavity, attached to the inner wall of the tube body, and the upper part of the flushing tube is There are several flower holes; two balloons are symmetrically arranged on both sides of the tube near the head, and a plurality of drainage holes are symmetrically arranged on the tube between the two balloons; the cavity of the balloon and the wall of the tube The water injection or air injection tube cavity of the balloon is connected; the main purpose of this scheme is to prevent the drainage tube from protruding from the inner side of the abdominal wall or chest wall, so when the drainage tube extends into the abdominal wall or chest wall, its direction of insertion is not to the drainage. The position of the tube is limited, so it is necessary to additionally fix the insertion direction of the drainage tube, which causes another kind of trouble, or directly put the end of the drainage tube on the bottom of the abdominal cavity or chest cavity, but this will cause the patient's Discomfort, and two balloons are symmetrically arranged on both sides of the tube near the head, and multiple drainage holes are symmetrically arranged on the tube between the two balloons

The balloon here is not a ring-shaped balloon fixed on the tube body, so it can only play the role of blocking the drainage tube from the cavity of the abdominal wall or chest wall, but it cannot prevent the leakage of fluid in the abdominal cavity or pleural cavity. Out of the situation (when the patient's body turns, it will cause the fluid in the abdominal cavity or pleural cavity to flow out from the wound in the abdominal wall or thoracic wall)
