Abstract

The thoracentesis drainage device belongs to the field of medical equipment, and is composed of a puncture needle, a drainage tube, a one-way drainage pump and a drainage bag connected in sequence, and has a simple structure, is convenient to use, does not require artificial suction, saves time and effort, and is low in cost. It integrates diagnosis and treatment, and can perform puncture, drainage and intrapleural administration. The repeated operations can be carried out as one operation, which obviously reduces the suffering of patients, can be widely used in hospitals and clinics at all levels and can develop international markets.

Description

Thoracentesis

本实用新型为一种胸腔穿刺引流器，属于医疗器械技术领域。The utility model relates to a chest cavity puncture drainage device, which belongs to the technical field of medical instruments.

目前临床上用于诊断或治疗的穿刺针性能单一，只能穿刺不能引流，需多次更换注射器人工抽吸引流，操作费时费力，容易导致逆行感染或继发性气胸，医务人员劳动强度大。而单一的引流管引流胸水无引流袋不能计量，易继发感染，且无速度控制器，不能控制引流速度易致胸膜反应是其缺陷。Currently, the puncture needles used clinically for diagnosis or treatment have single performance. They can only puncture but not drain, and manual suction and drainage need to be replaced many times. And single drainage tube drainage pleural effusion can not be measured without drainage bag, easy to secondary infection, and has no speed controller, can not control the drainage speed and is easy to cause pleural reaction is its defect.

本实用新型的目的在于克服以上缺点，提供一种操作简单，使用方便，不污染环境的胸穿引流器，它不仅可以胸腔穿刺、胸水引流，而且还可以胸腔内给药，不用人工抽吸，从而大大地减轻了医务人员的劳动强度。The purpose of this utility model is to overcome the above disadvantages, to provide a thoracic drainage device that is simple to operate, convenient to use, and does not pollute the environment. Thereby greatly reducing the labor intensity of medical personnel.

为了达到上述目的，本实用新型采用以下技术方案，现结合附图加以说明。In order to achieve the above object, the utility model adopts the following technical solutions, which are now described in conjunction with the accompanying drawings.

附图1是本实用新型的结构示意图。Accompanying drawing 1 is the structural representation of the utility model.

如图1所示，穿刺针(1)的尾端和引流管(3)的一端相连接，引流管的另一端和引流袋(4)相连接。引流管上近端按有单向引流泵(2)，远端另有一速度控制器(5)；引流袋上方装有固定用挂带(6)，表面有计量刻度(7)，其下方设有阀门(8)。As shown in Figure 1, the tail end of the puncture needle (1) is connected to one end of the drainage tube (3), and the other end of the drainage tube is connected to the drainage bag (4). There is a one-way drainage pump (2) on the proximal end of the drainage tube, and a speed controller (5) on the far end; a fixing strap (6) is installed on the top of the drainage bag, and a measuring scale (7) is arranged on the surface. There is a valve (8).

下面以实施例的形式对本实用新型做进一步说明。The utility model is described further below with the form of embodiment.

穿刺针为8-12号针头，长约5-8cm，针头座和直径为4-5mm、长度为50-60cm引流管的一端套接，其另一端和容量为1000ml的引流袋输入口相套接。引流管和引流袋均采用无色透明医用塑料。The puncture needle is a No. 8-12 needle, about 5-8cm long, the needle seat is socketed with one end of the drainage tube with a diameter of 4-5mm and a length of 50-60cm, and the other end is matched with the input port of the drainage bag with a capacity of 1000ml catch. Both the drainage tube and the drainage bag are made of colorless transparent medical plastic.

使用时，把引流袋上方的挂带挂在床边，先将速度控制器关闭，当穿刺针通过皮肤肌肉进入胸膜腔后就可见胸水流出，调节速度控制器控制胸水流速，由于单向引流泵的作用胸水单向外流。若需取样化验或排出袋内流体可打开引流袋下方的阀门，若需胸腔内给药关闭速度控制器，通过引流管注入药物。When using, hang the lanyard above the drainage bag on the bedside, first turn off the speed controller, when the puncture needle enters the pleural cavity through the skin and muscles, you can see the pleural fluid flow out, adjust the speed controller to control the flow rate of the pleural fluid, because the one-way drainage pump The role of pleural effusion unidirectional outflow. If it is necessary to take a sample test or discharge the fluid in the bag, the valve under the drainage bag can be opened, and if intrathoracic administration is required, the speed controller is closed, and the drug is injected through the drainage tube.

本实用新型是一种理想的医疗器械，适用于各级医院和诊所，并可开发国际市场，具有广泛的社会效益和经济效益。The utility model is an ideal medical device, which is suitable for hospitals and clinics at all levels, and can be developed into an international market, and has extensive social and economic benefits.
