AI Technical Summary
Existing tension pneumothorax puncture and drainage devices require separate operation of the puncture needle and adjustment mechanism, resulting in a window period that poses a risk of infection due to outside air entering the pleural cavity. Furthermore, their low integration level leads to secondary trauma.
A puncture and drainage device integrating drainage and decompression is designed. Through the sliding connection of the pull rod and the baffle, the drainage tube is immediately blocked when the puncture needle is pulled out. Combined with the limiting block, the gap period is avoided, and the drainage and decompression operations can be completed in one puncture.
This allows for drainage and decompression to be completed in a single puncture procedure, avoiding secondary trauma and infection risks, and improving the applicability and sealing protection of the device.

TECHNICAL FIELD
[0001] The present application relates to the technical field of puncture drainage, and in particular to a tension pneumothorax puncture drainage device for crush injury patients. BACKGROUND
[0002] Tension pneumothorax is caused by visceral pleura and lung tissue damage, and air continuously enters the pleural cavity; the damage site forms a flap, and gas continuously enters the pleural cavity but cannot be discharged, which will cause the air pressure in the chest to continuously rise, the lung tissue to be compressed and not to relax, and an emergency state of acute progressive respiratory and circulatory dysfunction. This is a common fatal acute and critical condition in pre-hospital emergency and emergency department. Among them, when treating crush injury patients, a tension pneumothorax puncture drainage device is needed.
[0003] At present, the tension pneumothorax puncture drainage device on the market often includes two treatment steps of pressure relief and drainage when treating tension pneumothorax, and often uses a puncture needle to pierce the chest cavity to relieve pressure and drain, and then uses a drainage tube to achieve the drainage effect. Since it is performed separately, two parts of the device are needed to achieve it, the integration degree is low, and the patient has secondary trauma. In the related technology, the puncture needle and the drainage tube are inserted into the patient's chest cavity together, the adjusting mechanism is inserted into the end of the drainage tube located outside, and the rotation is used to adjust which arc-shaped tube the drainage tube is connected to. According to the actual needs, water seal bottle drainage or pressure relief and drainage are selected. Compared with the prior art, the device integrates drainage and pressure relief and drainage in one device, and only needs to puncture the patient's chest cavity once during actual use, avoiding secondary trauma, achieving the beneficial effects of integrated drainage and pressure relief and drainage. However, there is a window period between the action of removing the puncture needle from the drainage tube and the action of inserting the adjusting mechanism into the drainage tube. At this time, the two ends of the drainage tube are in communication, which can easily cause external air to enter the pleural cavity, and there is a risk of infection. It has certain limitations and is not convenient to use. SUMMARY

[0013] Compared with the prior art, the utility model has the beneficial effects that: When the puncture needle is pulled out, the pull rod is pushed, the clamping block is inserted into the clamping groove, and the puncture needle is still in the cover at the same time. Then, the bottom of the drainage tube is blocked, the puncture needle is pulled outwards again, and the puncture needle is separated from the drainage tube.
