Medical Suction and Perfusion Platform
中文介绍
- 定义与性质：医用吸引灌注平台是一种重要的医疗器械，主要用于外科手术及一些内窥镜诊疗过程中，通过精准控制液体的灌注与吸引，为手术操作提供良好条件，属于手术辅助设备6。
- 结构与组成：一般由灌注装置、吸引装置、主控单元和监测系统等组成3。灌注装置包含储液容器、灌注泵和灌注管，用于储存和输送灌注液5。吸引装置由负压泵、吸引管和收集容器构成，可产生负压吸除废液3。主控单元负责整体功能控制与参数调节，监测系统通常有压力传感器等，用于实时监测腔内压力、流量等参数3。
- 工作原理：灌注装置根据手术需求，由灌注泵将储液容器中的液体（如生理盐水）通过灌注管输送到手术部位，以保持手术区域清晰、湿润，或为内窥镜提供清晰视野6。吸引装置则通过负压泵产生负压，经吸引管将手术部位的血液、组织液、碎屑等废液吸入收集容器3。同时，监测系统实时监测腔内压力和流量等数据，主控单元根据预设参数和监测数据，自动调节灌注泵和负压泵的工作状态，确保腔内压力稳定在安全范围3。
- 功能模式1：通常具备多种模式，如生理灌注模式，可提供稳定的基础灌注流量，维持手术区域正常生理环境；负压吸引模式，能根据需求调节负压，高效吸除废液；灌注吸引自动模式，可根据腔内液体压力值自动调节负压泵与灌注泵，使腔内液体压力维持在设定的安全范围。
- 应用场景：广泛应用于泌尿外科、肝胆外科、妇产科等多种科室的手术。如在泌尿外科的输尿管软镜碎石手术中，可配合碎石设备，在碎石时维持腔内压力，吸除结石碎片；在肝胆手术中，可用于清除手术视野中的血液和组织碎屑，保持视野清晰；在宫腔镜手术中，能为宫腔提供灌注，维持宫腔膨胀，同时吸除宫腔内的血液和分泌物4。
英语介绍
- Definition and nature：The medical suction and perfusion platform is an important medical device, mainly used in surgical operations and some endoscopic diagnosis and treatment processes. It provides good conditions for surgical operations through precise control of liquid perfusion and suction, and belongs to surgical – assisting equipment6.
- Structure and composition：It is generally composed of a perfusion device, a suction device, a main control unit and a monitoring system3. The perfusion device includes a liquid – storage container, a perfusion pump and a perfusion tube, which are used to store and transport perfusion fluid5. The suction device is composed of a negative – pressure pump, a suction tube and a collection container, which can generate negative pressure to suck out waste liquid3. The main control unit is responsible for overall function control and parameter adjustment, and the monitoring system usually has pressure sensors and other components, which are used to real – time monitor parameters such as intra – cavity pressure and flow rate3.
- Working principle：According to the surgical needs, the perfusion device uses the perfusion pump to transport the liquid (such as normal saline) in the liquid – storage container to the surgical site through the perfusion tube, so as to keep the surgical area clear and moist, or to provide a clear vision for the endoscope6. The suction device generates negative pressure through the negative – pressure pump, and sucks the waste liquid such as blood, tissue fluid and debris at the surgical site into the collection container through the suction tube3. At the same time, the monitoring system real – time monitors the data such as intra – cavity pressure and flow rate, and the main control unit automatically adjusts the working states of the perfusion pump and the negative – pressure pump according to the preset parameters and the monitored data, so as to ensure that the intra – cavity pressure is stable within a safe range3.
- Functional modes1：It usually has a variety of modes. For example, the physiological perfusion mode can provide a stable basic perfusion flow to maintain the normal physiological environment of the surgical area. The negative – pressure suction mode can adjust the negative pressure according to the needs to efficiently suck out waste liquid. The automatic perfusion and suction mode can automatically adjust the negative – pressure pump and the perfusion pump according to the intra – cavity liquid pressure value, so as to maintain the intra – cavity liquid pressure within the set safe range.
- Application scenarios：It is widely used in surgeries of various departments, such as urology, hepatobiliary surgery, and obstetrics and gynecology. For example, in urological ureteroscopic lithotripsy, it can cooperate with lithotripsy equipment to maintain intra – cavity pressure and suck out stone fragments during lithotripsy. In hepatobiliary surgery, it can be used to remove blood and tissue debris in the surgical field of view to keep the view clear. In hysteroscopic surgery, it can provide perfusion for the uterine cavity, maintain uterine cavity expansion, and at the same time suck out the blood and secretions in the uterine cavity4.
