技术领域 technical field
本实用新型属于医疗器械技术领域，更具体是涉及一次性胸腹腔穿刺套管针。The utility model belongs to the technical field of medical instruments, in particular to a disposable thoracoabdominal cavity puncture trocar.
背景技术 Background technique
临床上广泛运用胸腹腔穿刺术诊断与治疗胸腹腔疾患。目前胸腹腔穿刺术操作流程中仍使用带有乳胶管的钢针穿刺，抽液时需两人操作。这样操作医生很担心针尖刺着脏器，每抽一次液者重新穿刺一次，工作量大，容易污染环境，。许多医生多年的愿望：采用导管代替锋利的穿刺针进行胸腹腔抽液。Clinically, thoracentesis is widely used in the diagnosis and treatment of thoracic and abdominal diseases. At present, steel needles with latex tubes are still used in the operation process of thoracentesis, and two people are required to perform fluid extraction. In this way, the doctor is very worried about the needle tip piercing the viscera. Every time the liquid is pumped, the person will puncture again. The workload is heavy and the environment is easily polluted. The desire of many doctors for many years: to use catheters instead of sharp puncture needles for thoracoperitoneal fluid aspiration.
目前有报道用腹腔穿刺套管针、静脉留置针或中心静脉导管代替带有乳胶管的钢针进行胸腹腔穿刺引流。但这些医疗器材留置时易堵管不易固定，成本高。At present, it has been reported to replace the steel needle with latex tube for thoracoperitoneal drainage with a paracentesis trocar, venous catheter or central venous catheter. However, these medical devices are easy to block and not easy to fix when indwelling, and the cost is high.
实用新型内容 Utility model content
本实用新型的目的在于克服现有技术存在的不足，提供一次性胸腹腔穿刺套管针。本实用新型具有设计合理，结构简单，操作方便，使用安全、有效防止感染等优点。The purpose of the utility model is to overcome the deficiencies in the prior art and provide a disposable thoracoabdominal puncture trocar. The utility model has the advantages of reasonable design, simple structure, convenient operation, safe use, effective infection prevention and the like.
为达到上述目的，本实用新型采取了如下的技术方案：In order to achieve the above object, the utility model has taken the following technical solutions:
一次性胸腹腔穿刺套管针，由套管穿刺针、伞状针柄、双腔导管及防逆流装置组成；套管穿刺针与伞状针柄一端相连；双腔导管的一端连在伞状针柄上，另一端则连有防逆流装置。Disposable thoracoperitoneal trocar is composed of trocar puncture needle, umbrella-shaped needle handle, double-lumen catheter and anti-reflux device; trocar puncture needle is connected to one end of umbrella-shaped needle handle; one end of double-lumen catheter is connected to umbrella-shaped On the needle handle, the other end is connected with an anti-reflux device.
作为上述技术方案的改进，在套管穿刺针的侧面上开有侧孔。As an improvement of the above technical solution, a side hole is opened on the side of the cannula puncture needle.
作为上述技术方案的另一种改进，在双腔导管的前端还设有调速开关。As another improvement of the above technical solution, a speed regulating switch is also provided at the front end of the double lumen catheter.
与现有技术相比，本实用新型具有如下的有益效果：Compared with the prior art, the utility model has the following beneficial effects:
1.本实用新型很好的结合了留置针的特点，密闭设计，在穿刺成功后撤出针芯时，白色隔离塞能自动密封，保证医护人员免受体液污染。具有结构简单，操作方便，减少反复穿刺的痛苦，减轻医护人员的工作量。1. The utility model combines the characteristics of the indwelling needle well, and the airtight design, when the needle core is withdrawn after the puncture is successful, the white isolation plug can be automatically sealed to ensure that the medical staff are free from body fluid pollution. The utility model has the advantages of simple structure and convenient operation, reduces the pain of repeated puncture, and reduces the workload of medical staff.
2.本实用新型多侧孔套管，不易堵管，可延长置管时间。套管采用与组织相容性好的软质材料，套管在留置期间让病人感觉更为舒适。2. The multi-side hole casing of the utility model is not easy to block the tube and can prolong the time of tube placement. The cannula is made of soft material with good tissue compatibility, and the cannula makes the patient feel more comfortable during the indwelling period.
3.本实用新型为伞状针柄，不仅便于固定与引流，还使穿刺点保持无菌，防止感染。3. The utility model has an umbrella-shaped needle handle, which is not only convenient for fixation and drainage, but also keeps the puncture point sterile and prevents infection.
4.本实用新型针柄处分为二路，即为双导管。一路为胸腹腔引流(出路)；另一路为胸腹腔内用药(进路)。出路口设置在距针柄20厘米处，可接普通的一次性引流袋；进路口设置在距针柄10厘米处接肝素帽。双导管及引流管末端防逆流装置的设计，有效防止逆行感染。4. The needle handle of the utility model is divided into two channels, which are double catheters. One way is thoracoabdominal drainage (outlet); the other way is intraperitoneal medication (access). The outlet is set at 20 cm away from the needle handle, which can be connected with ordinary disposable drainage bag; the inlet is set at 10 cm away from the needle handle to connect with the heparin cap. The design of the double catheter and the anti-reflux device at the end of the drainage tube can effectively prevent retrograde infection.
