Description

Chest tube locking device

The present invention relates to a device for drainage tube, in particular to a blocking device for drainage control of chest tube.

The trauma-related mortality rate is increasing year by year, and the number of medical visits and medical expenses for trauma have also increased a lot. Among them, the fatality rate of thoracic trauma accounts for about 20-25% of trauma deaths, and thoracic trauma is also the second cause of trauma death. Most patients with thoracic trauma will experience symptoms such as shortness of breath and dyspnea, and during the treatment and examination process, pain and anxiety are often caused, and sometimes even the most basic physiological needs are affected. Such patients should receive active treatment as soon as possible when their condition changes.

The common treatment method is to drain the gas or liquid through the chest tube, so as to rebuild the negative pressure state of the chest cavity, so that the collapsed lung can be re-expanded. When the chest tube is placed for drainage, the chest tube drainage system must be kept unobstructed and relatively closed to the outside world. If the chest tube is broken or the joint connected to the chest tube slips off accidentally, a hemostatic clamp must be used immediately. Hold or reconnect the chest tube to prevent air from entering the chest cavity. However, because the patient does not carry hemostatic forceps with them, in the event of the aforementioned chest tube rupture In emergency situations, it is often impossible to clamp the chest tube in time, and it is necessary to urgently request the assistance of nearby medical personnel. This process is very critical and time-consuming, and careless handling may cause serious aggravation of the disease. Therefore, this medical treatment method of closing the chest tube with hemostatic forceps does have certain safety concerns and needs to be improved.

Accordingly, it is an object of the present invention to provide a chest tube closure device that ameliorates at least one of the disadvantages of the prior art.

Therefore, the chest tube locking device of the present invention is suitable for connecting and connecting between a chest tube and a drainage tube. The chest tube locking device includes a communication tube and a locking mechanism mounted on the communication tube.

The communication pipe includes a central pipe portion, two connecting pipe portions extending outward from the central pipe portion and used to communicate with the chest tube and the drainage pipe respectively, and a regulating pipe portion extending outward from the central pipe portion . The locking mechanism includes a piston arranged in the central pipe portion and airtightly blocked between the connecting pipe portions and the adjusting pipe portion, and a piston connected to the piston and extending axially out of the adjusting pipe portion along the adjusting pipe portion An adjustment unit outside the tube section, the adjustment unit operable to drive the piston in a latched position hermetically blocked between the connecting tube sections and the adjustment tube section, and a displacement into the adjustment tube section to cause the Changes between the open positions where the connection pipe is connected.

The effect of the present invention is: through the communication tube of the chest tube locking device and the With the structural design of the locking mechanism, the medical staff can quickly adjust the piston to the locking position by rotating the adjusting unit to immediately close the chest tube, so as to obtain more rescue time for the patient.
