Abdominal drainage tube fixing assembly and method for jointly clamping inside and outside abdominal wall

Abstract

The invention discloses an abdominal drainage tube fixing assembly and method for jointly clamping inside and outside the abdominal wall, and relates to the technical field of medical supplies. The abdominal drainage tube fixing assembly comprises a drainage tube, a hard sleeve, a flexible sleeve, an inner locking ring and an outer locking ring, wherein a buckle is arranged at one end of the hard sleeve, a chute is arranged at the other end of the hard sleeve, and a bayonet is arranged in the chute; a plurality of kidney-shaped holes are formed in the flexible sleeve, strip-shaped petals are formed between the adjacent kidney-shaped holes of the flexible sleeve, and the hard sleeve is movably sleeved with the flexible sleeve; external threads are arranged on the outer circular surface of the inner locking ring, convex teeth are arranged in an inner hole, and the inner locking ring is movably sleeved on the hard sleeve; an annular flash is arranged at one end of the outer locking ring, and an inner thread is arranged in the inner hole. The abdominal drainage tube indwelling and extubating training method is applied to an abdominal drainage tube fixing assembly jointly clamped inside and outside the abdominal wall, and acts on a human body abdomen model. The abdominal drainage tube fixing device solves the problem that a wound or external skin is easily injured due to infirm fixing.

Description

technical field [0001] The invention relates to the technical field of medical supplies, in particular to an abdominal drainage tube fixing component and method that are jointly clamped inside and outside the abdominal wall. Background technique [0002] Abdominal drainage tube is one of the most commonly used medical supplies in abdominal surgery. It is widely used in general surgery. However, in clinical practice, there are often adverse events that the drainage tube falls off from the abdominal cavity or penetrates into the abdominal cavity to cause infection. This is usually related to the patient's intraperitoneal The drainage tube is not fixed firmly. [0003] According to the literature survey, the fatality rate of patients who need re-cannulation after accidental extubation is as high as 25%, and the secondary infection rate of intubation reset is significantly higher than that of patients with planned extubation. [0004] The current routine fixation method of clin...
