【摘要】：在現代醫(yī)療過程中,皮下靜脈穿刺已成為重要的醫(yī)療手段,無論是在診斷或是治療的過程中都起著重要的作用。然而,傳統(tǒng)的皮下靜脈穿刺過程通常是由操作人員裸眼對穿刺對象的皮下靜脈血管進行觀察與定位。因此,該操作過程將依賴于操作人員的操作經驗、操作環(huán)境以及穿刺對象特征等因素。如當遇到肥胖、膚色較深或皮膚腫脹等穿刺對象,操作人員將難以直接通過裸眼對穿刺對象的皮下靜脈血管進行觀察與定位,從而使皮下靜脈穿刺操作難以進行。針對上述在皮下靜脈穿刺過程中遇到的問題,隨著科學技術的發(fā)展與進步,出現了皮下靜脈顯影系統(tǒng)。皮下靜脈顯影系統(tǒng)通過提高穿刺對象的皮下靜脈血管與其周圍組織的對比度,輔助操作人員對穿刺對象進行皮下靜脈血管定位,使操作人員能準確地定位至穿刺對象的目標穿刺血管,從而降低了皮下靜脈穿刺操作的難度和風險。本文對目前具有的幾種皮下靜脈顯影系統(tǒng)進行研究并分類,同時對它們的工作原理、成像特點、系統(tǒng)架構等方面進行分析。通過對這幾類系統(tǒng)的分析結果進行比較和總結,本文提出了基于Zynq異構片上系統(tǒng)的皮下靜脈顯影系統(tǒng)架構。Zynq是由Xilinx公司推出的全可編程異構片上系統(tǒng)平臺。該平臺在單片芯片上集成了處理系統(tǒng)PS(Processing System)部分和可編程邏輯PL(Programmable Logic)部分。處理系統(tǒng)PS部分可提供高速的基于程序的運算性能,而可編程邏輯PL部分則可提供靈活的基于硬件的處理能力,兩部分通過AXI(Advanced Extensible Interface)總線連接,具有很高的數據傳輸帶寬。因此,基于Zynq異構片上系統(tǒng)的皮下靜脈顯影系統(tǒng)架構具有高運算性能、控制靈活、系統(tǒng)體積小等特點。根據提出的設計方案,本文對設計方案進行實現,并對其功能進行驗證,實驗結果顯示該系統(tǒng)滿足設計方案的預期目標,可實現皮下靜脈圖像顯影增強功能,并具有高運算性能、控制靈活、系統(tǒng)體積小等特點。該系統(tǒng)可輔助對皮下靜脈血管進行觀察與定位,有助于提高皮下靜脈穿刺操作的成功率,這無論是對個人健康、家庭幸福以及社會的穩(wěn)定發(fā)展都起著積極的作用。
[Abstract]:In modern medical process, subcutaneous venipuncture has become an important medical means, both in the diagnosis and treatment process plays an important role. However, the traditional procedure of subcutaneous venipuncture is usually observed and localized by the operator naked eyes. Therefore, the operation process will depend on the operator's operation experience, operating environment and puncture object characteristics. For example, when the puncture objects such as obesity, dark skin color or skin swelling are encountered, it will be difficult for the operator to observe and locate the subcutaneous vein vessels directly through the naked eye, thus making the subcutaneous vein puncture difficult to carry out. In view of the above problems encountered in the process of subcutaneous venipuncture, with the development and progress of science and technology, subcutaneous vein imaging system appeared. By improving the contrast between the subcutaneous vein vessel and the surrounding tissue, the subcutaneous vein development system assists the operator to locate the subcutaneous vein vessel of the puncture object. Therefore, the difficulty and risk of subcutaneous venipuncture can be reduced. In this paper, several kinds of subcutaneous vein imaging systems are studied and classified, and their working principle, imaging characteristics and system architecture are analyzed. By comparing and summarizing the analysis results of these kinds of systems, this paper presents the architecture of subcutaneous vein development system based on Zynq isomerous system. Zynq is a fully programmable isomerous system platform developed by Xilinx Company. The platform integrates the processing system PS(Processing system and the programmable logic PL(Programmable logic on a single chip. The PS part of the processing system can provide high-speed program-based computing performance, while the programmable logic PL part can provide flexible hardware-based processing capability. The two parts are connected by the AXI(Advanced Extensible Interface bus and have a high data transmission bandwidth. Therefore, the architecture of subcutaneous vein development system based on Zynq isomerous system has the advantages of high computational performance, flexible control and small system volume. According to the proposed design scheme, the design scheme is implemented in this paper, and its function is verified. The experimental results show that the system meets the expected goal of the design scheme and can realize the enhancement function of subcutaneous vein image development. And has the high computation performance, the control is flexible, the system volume is small and so on characteristic. The system can assist the observation and localization of subcutaneous vein vessels, and help to improve the success rate of subcutaneous venipuncture, which plays an active role in personal health, family happiness and the stable development of society.
