Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of war injury first-aid medical devices, in particular to a percutaneous puncture abdominal war injury early-stage multifunctional first-aid kit. BACKGROUND

[0002] In modern warfare and high-energy trauma scenes, the incidence of abdominal war injury accounts for 15%-20% of the whole body trauma, among which the rupture of abdominal cavity organs (such as stomach, small intestine, colon, gallbladder) is a typical type of severe injury. After the rupture of the hollow organs, the highly corrosive digestive juice (such as gastric acid, bile), feces containing a large number of pathogenic bacteria and other pollutants will quickly spread to the abdominal cavity, and the probability of causing abdominal infection within 6 hours is more than 70%; if the infection is not controlled in time, the risk of progressing to septic shock within 24 hours is 40%, and the mortality rate is more than 35%, which is one of the core inducements for the death of abdominal war injury patients within the "golden 1 hour" after injury.

[0003] At present, the treatment of abdominal war injury relies on the ladder process of "accurate diagnosis-infection control-damage repair": with the popularization of portable abdominal B-ultrasound (weight <5 kg), mobile CT (adapted to medical vehicles / warships) and other imaging equipment in the field medical unit, medical staff can complete the positioning and diagnosis of the abdominal infection site (such as liver abscess, pelvic abscess) within 30 minutes after injury, but the subsequent infection control link still faces significant technical bottlenecks. The existing infection control methods mainly fall into two categories: one is laparotomy, which requires full anesthesia equipment, surgical shadowless lamp and professional surgical team, and the operation time is more than 90 minutes on average, and the postoperative recovery period is long, which is completely unable to adapt to the rapid treatment needs in the field; the second is the clinically mainstream percutaneous puncture catheter drainage (PCD) technology guided by B-ultrasound / CT, which is relatively simple to operate, but the instruments used have multiple inherent defects.

[0004] Firstly, the drainage catheter (such as pig tail catheter, central venous catheter) used in traditional PCD technology has an inner diameter of only 2-4 mm, the number of side holes is only 3-5, and the diameter of the side hole is <2 mm, so the abdominal cavity viscous pus, necrotic tissue fragments and fecal residues are easy to block the lumen - clinical data shows that even if 3-5 times of daily manual normal saline flushing is performed, 62% of patients still have tube blockage within 24 hours, resulting in residual infection foci, which requires secondary puncture, not only prolonging the treatment period, but also increasing the pain and infection spread risk of patients. Secondly, the existing PCD technology lacks a "flushing-drainage" integrated device: manual flushing cannot guarantee that the flushing liquid uniformly covers the infection site, which is easy to form a "flushing blind area"; negative pressure suction relies on a simple syringe for suction, and the negative pressure value fluctuates greatly (-0.01~-0.08MPa), and too high negative pressure will damage the fragile tissues (such as intestinal wall, peritoneum) in the abdominal cavity, and too low negative pressure will not completely drain.

[0005] In addition, the field treatment has high requirements for the "portability, integration and rapid deployment" of equipment, and the existing PCD related instruments are mostly scattered components (puncture needle, drainage tube, flushing fluid bag and negative pressure device are placed separately), and medical staff need to assemble them on site in a bumpy medical vehicle / warship, which takes an average of 15 minutes to assemble, and is easy to cause instrument pollution (about 8% pollution rate) due to operation errors; at the same time, there is a lack of special depth control and positioning auxiliary structure during puncture, and the puncture depth is only determined by the experience of medical staff, which is easy to damage blood vessels (such as abdominal aortic branches) or solid organs (such as liver and spleen) in the abdominal cavity due to deviation, further increasing the risk of treatment.

[0006] In summary, in the field of early infection control of abdominal war injury, there is an urgent need for an emergency kit that can cooperate with portable imaging equipment, has precise puncture guidance, continuous and stable flushing and drainage, anti-clogging tube, multifunctional integration and portability, to break through the technical bottleneck of "unable to quickly and effectively control infection after diagnosis", and meet the needs of rapid, accurate, safe and efficient treatment in the field.

[0026] The following description, in conjunction with the accompanying drawings and specific embodiments, provides further details: Example 1 like Figure 1As shown, a multifunctional early first aid kit for percutaneous abdominal trauma includes a Trocar puncture component 1, a double cannula 2, an external connector 3, an irrigation component 5, a collection bottle 7, and a negative pressure pump 8. The Trocar puncture component 1 is used to puncture the patient's abdominal cavity. The double cannula 2 is adapted to the Trocar puncture component 1 and is guided by the Trocar puncture component 1 to be inserted into the site of infection in the abdominal cavity. The double cannula 2 and the Trocar puncture component 1 facilitate both puncture of the patient's abdominal cavity and insertion of the double cannula 2 into the patient's abdominal cavity, thereby facilitating irrigation and drainage of the patient's abdominal cavity using the double cannula 2.

[0044] Working principle: In use, firstly, the patient's abdominal cavity is punctured using the Trocar puncture assembly 1. After puncture, the double cannula 2 is guided into the site of infection in the abdominal cavity through the assembly. At the same time, sampling can be completed with the help of the sampling tube 14 on the side of the Trocar puncture assembly 1. The inner side of the double cannula 2 is divided into an irrigation channel and a negative pressure drainage channel by a partition plate 22. An external connector 3 is installed at its open end. The two plugs 4431 of the external connector 3 are respectively inserted into two independent channels 23. The two external tubes 32 on the outer side are respectively connected to the irrigation tube 4 and the drainage tube 6. Next, the flushing assembly 5 is connected to the flushing channel of the double-walled tube 2 via the flushing tube 4. Physiological saline enters the abdominal cavity through the reservoir bag 51, connecting tube 513, throttle valve 514, flushing tube 4, and flushing channel. Multiple side holes 21 on the front side of the double-walled tube 2 further facilitate the even drainage of physiological saline into the abdominal cavity. Simultaneously, the air inlet of the negative pressure pump 8 is connected to the top of the collection bottle 7 via the suction tube 9. By adjusting the pressure adjustment knob 81 on the front of the negative pressure pump 8, a negative pressure is created inside the collection bottle 7, allowing the viscous pus and necrotic tissue in the abdominal cavity to be flushed out. After rinsing and flushing, the fluid enters the collection bottle 7 through the side hole 21 of the double sleeve 2, the negative pressure drainage channel, the drainage tube 6, the collection bottle 7, the drainage connector 721, and the suction tube 723 to achieve centralized collection, ultimately achieving simultaneous flushing and drainage of the abdominal cavity; in addition, when not in use, the Trocar puncture assembly 1, the double sleeve 2, the external connector 3, the flushing tube 4, the flushing assembly 5, and the drainage tube 6 can be stored together with the collection bottle 7 and the negative pressure pump 8 fixed in the storage box 10, which is convenient for battlefield carrying and quick assembly and use.

[0045] In summary, compared with existing technologies, the drainage anti-blockage tube of this application features: the side hole 21 on the side of the drainage channel inside the double-walled tube 2, in conjunction with continuous negative pressure, can effectively drain viscous pus and necrotic tissue, reducing the tube blockage rate; the continuous flushing channel inside the double-walled tube 2 can flush the lumen in real time, further preventing blockage. Precise and safe puncture: the scale design and positioning marker of the Trocar puncture component 1, combined with portable imaging equipment, can precisely control the puncture depth, avoiding damage to intra-abdominal blood vessels and solid organs. Multifunctional integration: integrating puncture, sampling, flushing, and drainage, eliminating the need for on-site assembly of scattered instruments, shortening deployment time, and meeting the "golden hour" treatment needs in battlefields. High portability and adaptability: the entire set of components is stored inside the storage box 10, adaptable to battlefield scenarios such as medical vehicles, warships, and ambulances, and includes built-in disinfection and anesthesia supplies, eliminating the need for additional carrying. Controllable and safe operation: The flow regulating valve 42 of the continuous flushing component 5 and the pressure regulating knob 81 of the negative pressure suction component can be dynamically adjusted according to the patient's infection level. The anti-backflow valve prevents contaminants from flowing back, and the antibacterial dressing reduces the risk of infection at the puncture site.
