【摘要】: 近年來(lái),緊身褲襪、塑身內(nèi)衣、牛仔褲等各類(lèi)緊身服裝被眾多消費(fèi)者所青睞,緊身壓迫可能對(duì)人體形態(tài)和生理系統(tǒng)產(chǎn)生正面或負(fù)面的復(fù)雜影響,著裝壓迫的安全性和舒適性越來(lái)越多地受到從業(yè)人員和消費(fèi)者的重視。 本課題著眼于調(diào)查下肢著裝壓迫對(duì)皮膚血流的影響。選擇五位健康的男研究生為受試者,以腳踝和小腿為研究對(duì)象,采用血壓計(jì)對(duì)下肢交替加壓(無(wú)壓和有壓)模擬著裝壓迫狀態(tài),測(cè)試受壓部位的皮膚血流信號(hào)。主要從壓力大小、姿勢(shì)的影響、部位的差異三個(gè)方面比較了壓迫引起的皮膚血流變化,同時(shí)利用小波分析方法對(duì)皮膚血流信號(hào)進(jìn)行頻譜分析,并結(jié)合微循環(huán)控制理論探討壓迫引起皮膚血流變化的作用機(jī)制。分析皮膚血流的變化,得到的主要結(jié)果如下:(1)施加壓力在一定范圍內(nèi),受壓部位的皮膚血流量增加,且血流增量隨壓力的增加而變大;(2)當(dāng)壓力超過(guò)某一臨界值時(shí),皮膚血流量增量開(kāi)始減小,躺姿下的該臨界值小于坐姿,而腳踝處的臨界值比小腿處高;(3)如果壓力進(jìn)一步增加,皮膚血流又會(huì)轉(zhuǎn)而下降。對(duì)血流信號(hào)進(jìn)行小波分析發(fā)現(xiàn):加壓時(shí),肌原性活動(dòng)峰振幅增加,其特征頻率下降。 分析壓迫引起皮膚血流變化的作用機(jī)制:一方面一定的機(jī)械壓迫使蘊(yùn)含在皮膚里的微動(dòng)脈被擠壓,微動(dòng)脈里的血流量減少,流向其連接的毛細(xì)血管內(nèi)的血流受阻,為了獲得同樣的氧濃度,毛細(xì)血管開(kāi)放時(shí)間延長(zhǎng),從而毛細(xì)血管的開(kāi)閉活動(dòng)頻率減小,毛細(xì)血管開(kāi)放率增加,皮膚血流增加;另一方面當(dāng)外部壓迫大于微動(dòng)脈平均血壓,部分微動(dòng)脈血管被壓扁,流向其連接的毛細(xì)血管內(nèi)的血流被阻斷,從而皮膚血流減少。皮膚血流的上升、增量大小以及下降是以上兩方面作用平衡的結(jié)果。本研究結(jié)果將為緊身類(lèi)服裝壓力設(shè)計(jì)與開(kāi)發(fā)提供生理學(xué)的基礎(chǔ),同時(shí)也為消費(fèi)者的穿著與選擇提供科學(xué)指導(dǎo)。
[Abstract]:In recent years, tight fitting tights, plastic underwear, jeans and other tight clothing have been favored by many consumers. Tight compression may have a positive or negative impact on human form and physiological system. The safety and comfort of loading oppression are being paid more and more attention by employees and consumers.
The subject is to investigate the influence of lower extremity dressing compression on skin blood flow. Five healthy male postgraduates were selected as subjects with ankle and calf as the research object, and the pressure meter was used to simulate the compression state of the lower limb alternately pressure (no pressure and pressure) and to test the skin blood flow signals at the compression position, mainly from the size of pressure and posture. The variation of skin blood flow caused by oppression was compared in three aspects. At the same time, the skin blood flow signal was analyzed by wavelet analysis, and the mechanism of skin blood flow changes caused by compression was discussed with the theory of microcirculation control. The changes of skin blood flow were analyzed. The main results were as follows: (1) exerting pressure In a certain range, the blood flow of the skin increased and the increment of blood flow increased with the increase of pressure. (2) when the pressure exceeded a certain critical value, the increment of blood flow in the skin began to decrease, the critical value under the lying position was smaller than the sitting position, and the critical value at the ankle was higher than that in the small leg; (3) the blood flow would turn if the pressure was further increased. The wavelet analysis of blood flow signals showed that the peak amplitude of myogenic activity increased and the characteristic frequency decreased.
Analysis of the mechanism of skin blood flow changes caused by compression: on the one hand, certain mechanical compression makes the microarteries contained in the skin squeezed, the blood flow in the arteriole decreases, and the blood flow in the capillaries connected to the blood is blocked. In order to obtain the same oxygen concentration, the opening time of the capillary blood tube is prolonged, thus the capillaries are open and closed. On the other hand, when the external compression is greater than the mean blood pressure of the Microartery, the blood flow in the capillary of the capillary is blocked and the blood flow is reduced. The blood flow of the skin is reduced. The increase of the skin blood flow, the increment and the decline are two aspects. The results of this study will provide a physiological basis for the design and development of tight clothing pressure, and provide scientific guidance for the wear and selection of consumers.
