Description

Chest Tube Lockout Device

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

Trauma-related mortality is increasing year by year, and the number of trauma-related medical visits and medical expenses have also increased a lot. Among them, the mortality rate of chest trauma accounts for about 20-25% of traumatic deaths, and chest trauma is also the second cause of traumatic death. Most patients with chest trauma will experience shortness of breath, dyspnea and other symptoms, and in the process of receiving treatment and examination, it often causes pain and anxiety and many other discomforts, and sometimes even the most basic physiological needs are affected. For such patients, when their condition changes, they should be actively treated as soon as possible.

The common treatment method is to perform drainage through a chest tube to drain air or liquid, so as to restore the negative pressure state in the chest cavity, so that the collapsed lung can be re-expanded. Patients with chest tube drainage must keep the chest tube drainage system unobstructed and sealed relative to the outside world during activities. If the chest tube breaks or the joint connected to the chest tube accidentally slips off, hemostatic forceps must be used immediately Hold the chest tube or reconnect the connector to prevent air from entering the chest cavity. However, because patients do not carry hemostatic forceps with them, in the event of an emergency such as a chest tube rupture, they often cannot clamp the chest tube in time, and must urgently ask nearby medical personnel for assistance. This process is very critical and time-consuming. Careless handling can easily lead to serious exacerbation of the condition. Therefore, this medical treatment method of closing the chest tube through a hemostat does have certain safety concerns, and needs to be improved.

Finally, the adjustment member 61 is driven to rotate relative to the adjustment pipe portion 33, so as to drive the adjustment member 61 to change to the second card with the convex card portion 613 against the second positioning surface 625 of the second positioning member 624. Arriving at the position, the piston 5 can be stably fixed at the blocking position.

When the piston 5 is to be transferred from the locked position to the open position, the adjustment member 61 is operated in reverse steps, and the adjustment member 61 is first driven to change from the second clamping position to the adjustable position, and the The adjusting member 61 is pulled outward until the protrusion 613 passes through the first through hole 623 , at this time, the piston 5 is already at the open position. Finally, the adjusting member 61 is driven to rotate to the second engaging position, so that the piston 5 can be stably fixed at the open position.

In the second embodiment, the positioning module 62 is defined by the first positioning member 621 and the second positioning member 624 which are spaced apart to define the first positioning surface 622 and the second positioning surface 625 respectively, but the implementation Meanwhile, in other embodiments of the present invention, the positioning module 62 can also be designed as a single component having the first positioning surface 622 and the second positioning surface 625 opposite to each other. In addition, in another embodiment of the present invention, it is not necessary that the first through hole 623 of the first positioning member 621 and the second through hole 626 of the second positioning member 624 correspond to each other in the axial direction. The shape of the first through hole 623 and the second through hole 626 is not limited to the one shown in the figure, and it can also be designed to extend to the first positioning part 621 and the second positioning part 624 respectively. The peripheral edge, and can be further designed to extend and open into a fan shape along its peripheral edge, as long as it can allow the axial displacement of the convex clamping portion 643 to pass through.
