Technical Field
[0001] The utility model discloses a medical auxiliary device, in particular to a disposable first-line emergency simple thoracentesis negative pressure drainage suit. Background Art
[0002] At present, the main solution for first-line emergency treatment of tension pneumothorax is thoracentesis and decompression, which requires first-line rescue personnel to make a diagnosis and perform emergency thoracentesis and decompression. However, thoracentesis can only temporarily solve the problem of tension pneumothorax. As we all know, tension pneumothorax refers to the appearance of a one-way ventilation valve in the chest wall or lungs due to injury, resulting in increasing chest gas and compression of the lungs. This process will continue to occur, and a single thoracentesis cannot solve the problem. In the first-line of emergency treatment with a large number of patients, a lack of medical staff, or insufficient monitoring, there is an urgent need for a simple and easy-to-operate closed chest drainage kit suitable for the first-line of emergency treatment that can solve tension pneumothorax and subsequent thoracic hemothorax and other problems at one time.

DETAILED DESCRIPTION
[0021] The utility model is further described below in conjunction with the accompanying drawings.
[0022] Disposable first-line emergency simple thoracentesis negative pressure drainage kit, including Figure 1 The puncture needle 1 shown, such as Figure 2 The chest drainage device shown, such as Figure 4 Drainage device chest wall fixation device as shown Figure 5 The three-way valve 10 shown and Figure 6 The steering valve 9 is shown.
[0023] The chest drainage device comprises a chest wall external fixing plate 4, the upper surface of which is provided with a marking horizontal line 5 in the radial direction. A through hole is opened in the center of the chest wall external fixing plate 4, a threaded connection port 6 is provided on the upper end surface of the through hole, and a drainage tube 7 is connected to the lower end surface of the through hole.
[0024] like Figure 3 As shown, the tip of the puncture needle 1 can be inserted into the threaded connection port 6 and then pass through the drainage tube 7 with an interference fit, and extend from the bottom outlet of the drainage tube 7. After the puncture needle and the drainage tube are successfully punctured into the chest cavity, the puncture needle can slide out from the drainage tube 7, leaving the drainage tube 7 in the chest cavity, and the chest wall external fixing plate 4 is attached to the outer surface of the chest wall. Preferably, the surface of the puncture needle 1 is provided with a scale line 3. It can be used to assist the doctor to understand the puncture depth during puncture. The top of the puncture needle 1 is provided with a puncture needle handle 2. It is convenient for the doctor to operate.
[0025] The chest wall fixing device of the drainage device includes a fixing patch 8 with a central opening, and a protective film is attached to the adhesive surface of the fixing patch 8. After removing the protective film, the adhesive surface of the fixing patch 8 can be applied to the outer surface of the chest wall external fixing plate 4 and the chest wall around the chest wall external fixing plate. While the chest wall external fixing plate is fixed to the chest wall, the threaded connection port 6 can extend from the central opening of the fixing patch 8.
[0026] The connecting valve includes a steering valve 9 and a three-way valve 10. The steering valve 9 is an L-shaped structure. One end of the steering valve 9 is connected to the threaded connection port 6, and the other end of the steering valve 9 is connected to the liquid inlet of the three-way valve 10 through a pipeline. The first liquid outlet of the three-way valve 10 is connected to a negative pressure suction device or a drainage bag, and the second liquid outlet of the three-way valve 10 is used for suction or perfusion to maintain the pipeline unobstructed.
[0027] When using, Figure 7 As shown, connect the auxiliary puncture needle to the chest drainage device, determine the 4th to 5th ribs in the mid-axillary line, and the upper edge of the ribs enters the 4th to 5th intercostal space in the mid-axillary line. After disinfection and anesthesia, wear sterile gloves, hold the puncture needle handle, make the horizontal line marked on the chest wall external fixation plate flush with the upper edge of the 4th to 5th ribs in the mid-axillary line, make the puncture needle perpendicular to the chest wall, and apply force evenly. Focus on the auxiliary scale line on the puncture needle, wait until there is a breakthrough feeling in the hand, and the scale is accurate, push the chest wall external fixation plate toward the chest wall with one hand, and pull out the puncture needle with one hand to allow the drainage tube to enter the chest cavity. Use an empty syringe to aspirate the threaded connection port. If there is gas or bloody liquid flowing out smoothly, it is determined that the chest drainage device is correctly in place. If there is no gas or liquid, or the resistance is very large, insert the auxiliary puncture needle again for adjustment. After confirming the accurate position, use the chest wall fixing device of the drainage device to fix the chest drainage device, uncover the protective film of the chest wall fixing device of the drainage device, expose the adhesive surface, and expose the threaded connection port from the central opening of the fixing patch. The adhesive surface of the fixing patch can be applied to the outer surface of the chest wall external fixing plate and the chest wall around the chest wall external fixing plate, and the chest wall external fixing plate is fixed to the chest wall. Take out the steering valve and rotate and fix one end of the steering valve to the threaded connection port. The other end of the steering valve 9 is connected to the liquid inlet of the three-way valve 10 through a pipeline. The first liquid outlet of the three-way valve 10 is connected to a negative pressure suction device or a drainage bag, and the second liquid outlet of the three-way valve 10 is used for suction or perfusion to maintain the pipeline unobstructed. In addition, the steering valve described in this embodiment is fixed to the skin through a thread and a threaded connection port to reduce the risk of damage during pressure and transportation.
[0028] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
