Description
技术领域technical field
本实用新型属于医疗器械领域，具体涉及一种一次性嵌套式胸腔闭式引流管。The utility model belongs to the field of medical equipment, in particular to a disposable nested chest closed drainage tube.
背景技术Background technique
胸部手术或外伤后的患者需要胸腔需置入胸腔闭式引流管，使引流液经胸腔闭式引流管流出体外。但目前所使用的胸腔闭式引流管仅为一根软管，其一端插在病人胸腔内，另一端位于病人体外，并通过连接头与闭式引流瓶相连，形成封闭结构。当需要对病人胸腔内进行给药时，一种方法为：医护人员拔掉连接头，将药物直接灌入软管内，使药物沿软管流入病人胸腔，并且在给药时为了防止空气进入软管从而造成病人气胸，医护人员在将药物灌入软管时要适时的捏住软管的不同部位，操作难度较大，常需要多人协同完成操作；另外使用同一根通道同时作为引流液的流出管和给药管，使病人逆行感染的风险增大；其次给药的部位和药物的停留时间都不能准确的得到控制，影响药效。另一种方法是对病人另行穿刺，穿入另外一根软管进行给药，这种方法虽然降低了逆行感染的风险，但重新穿刺会大大增加病人的痛苦，而且两次穿刺的位置需要严格控制，若经同一穿刺孔置管，空气有可能从两个软管间形成的缝隙进入病人胸腔，从而导致病人气胸。Patients after thoracic surgery or trauma need to have a closed thoracic drainage tube placed in the thoracic cavity, so that the drainage fluid can flow out of the body through the closed thoracic drainage tube. But the closed chest cavity drainage tube used at present is only a flexible pipe, and its one end is inserted in patient's chest cavity, and the other end is positioned at patient's body, and links to each other with closed drainage bottle by connector, forms closed structure. When it is necessary to administer medicine to the patient's chest cavity, one method is: the medical staff pulls out the connector, pours the medicine directly into the hose, so that the medicine flows into the patient's chest cavity along the hose, and in order to prevent air from entering The hose causes pneumothorax to the patient. When the medical staff pours the medicine into the hose, they must pinch different parts of the hose in a timely manner. The operation is difficult and often requires the cooperation of multiple people to complete the operation; in addition, the same channel is used as the drainage fluid at the same time The outflow tube and the drug delivery tube increase the risk of retrograde infection of the patient; secondly, the site of drug delivery and the residence time of the drug cannot be accurately controlled, which affects the efficacy of the drug. Another method is to puncture the patient separately and inject another flexible tube for administration. Although this method reduces the risk of retrograde infection, re-puncture will greatly increase the pain of the patient, and the position of the two punctures needs to be strictly controlled. Control, if the tube is placed through the same puncture hole, air may enter the patient's chest cavity from the gap formed between the two tubes, thereby causing the patient's pneumothorax.
