Description
Technical Field
The utility model relates to the technical field of medical supplies, in particular to an abdominal cavity drainage tube fixing component for joint clamping inside and outside a abdominal wall.
Background
The abdominal cavity drainage tube is one of the most commonly used medical supplies in abdominal surgery, and is widely used in general surgery, but in the clinical practice process, the drainage tube is frequently fallen off from the abdominal cavity or enters the abdominal cavity to cause the adverse events of infection, which is usually related to the weak fixation of the drainage tube in the abdominal cavity of a patient.
According to literature investigation, the fatality rate of patients needing to be subjected to intubation replacement after accidental intubation is up to 25%, and the secondary infection rate of intubation replacement is obviously higher than that of patients subjected to planned intubation.
The conventional fixing method of the clinical abdominal cavity drainage tube at present is to sew the drainage tube on the skin of a patient by using a suture, and has the following defects:
1. the patient's postoperative activity often causes the traction displacement of the drainage tube, suture fracture, slippage, the above-mentioned condition of fixing not firmly is unfavorable for the patient's postoperative early stage to get out of bed activity, thus make the peristaltic function of gastrointestinal tract of the patient resume the speed to slow down, and increase the risk of infection, even lead to the abdominal cavity to accumulate pus or abscess to form;
2. the traction of the suture line easily causes pain at the intubation part of a patient, the patient easily becomes fussy and irritable under the driving of the pain, and the overstimulation of the autonomous tube drawing action is adopted, so that the tube needs to be replaced, and the infection is easily caused.
The external fixing mode of the Simle button or the 3M adhesive tape is adopted on the market, the defects existing in the mode of fixing the drainage tube by a suture can be overcome to a certain degree, but the fixing mode can cause certain damage to the wound and the external skin, the abdominal cavity drainage tube cannot be completely and effectively prevented from slipping, and a serious patient can cause infection, so that the external fixing mode is not used in a large range in the current market.
