本發明涉及一種醫療器械，特別涉及一種輸液用的流速調節器。The present invention relates to a medical device, and more particularly to a flow rate regulator for infusion.
輸液時的流速控制是非常重要的，合理的流速有助於提高療效，減少輸液時的風險。臨床中，醫囑在一般情況下有以滴速下達，病情較重或特殊需要時會以流量下達，特殊用藥要求流速精準到「滴」。特別地，對心功能不全、兒童、新生兒、老年病人、危重病人進行輸液時，如果輸液速度過快，單位時間進入體內的液體過多或藥物劑量過大，會誘發心力衰竭、血壓下降過快等導致病人病情加重。如果輸液速度過慢，單位時間進入體內的液體不足或藥物劑量過少，會導致無法糾正休克、血壓居高不下等。輸液速度和輸液量不精準，輕則耽誤治療，影響病人病情恢復和加重病人經濟負擔；重則延誤搶救時機，導致病人病情加重甚至死亡。Flow rate control during infusion is very important, and a reasonable flow rate helps to improve the efficacy and reduce the risk of infusion. In clinical practice, the doctor's order is usually delivered at a drip rate. If the condition is heavier or special needs, the flow rate will be released. The flow rate of the special medication is accurate to the "drop". In particular, when infusion of heart dysfunction, children, newborns, elderly patients, and critically ill patients, if the infusion rate is too fast, too much liquid per unit time or excessive dose of the drug will induce heart failure, blood pressure drops too fast, etc. Causes the patient to get worse. If the infusion rate is too slow, the amount of fluid entering the body per unit time or the dose of the drug is too small, which may result in failure to correct shock and high blood pressure. The infusion speed and infusion volume are not accurate, and the treatment is delayed, which affects the recovery of the patient's condition and aggravates the patient's economic burden. When the delay is delayed, the patient's condition is aggravated or even died.
臨床上也有使用流量設定式輸液器，但操作者往往無法直接按滴速醫囑處理，需花費一定時間進行換算，延誤治療。習知的流量設定式輸液器均採用無段調節輸液通道橫截面大小的方法，僅設有若干個輸液流量刻度標識可直接簡單估讀，可使用標識刻度間數值跨度較大，即使對應某一刻度進行調速，實際液流通道與刻度標識仍會存在一定的對位偏差導致實際流速偏差，當使用非輸液流量標識刻度時需由操作者進行估算，但臨床上估算值往往偏差較大，導致實際流速偏差更大。Clinically, there is also a flow setting type infusion set, but the operator often cannot directly treat the drip speed, and it takes a certain time to convert and delay the treatment. The conventional flow-setting infusion set adopts a method of adjusting the cross-sectional size of the infusion channel without a segment. Only a plurality of infusion flow scale marks can be directly estimated, and the value span between the used scales can be used even if it corresponds to a certain moment. The speed is adjusted, and the actual flow channel and the scale mark still have a certain deviation of the deviation, which leads to the actual flow velocity deviation. When the non-infusion flow identification scale is used, the operator needs to estimate it, but the clinical estimation value tends to be biased. This causes the actual flow rate deviation to be greater.
習知的輸液流速調節器的基本原理大致相同，普遍通過擠壓輸液導管使其發生形變，改變導管的橫截面積來調節流速。這種調節方式簡便，可以實現流速的無段調節，但是存在難以精確度量流速，需要進行多次調節才可以達到預期值。流量的調節更多依賴於操作者的經驗，而非流速調節器本身。在需要精確控制流速調控的時候，無法應用。The basic principles of conventional infusion flow rate regulators are generally the same, generally by squeezing the infusion catheter to deform it, changing the cross-sectional area of the catheter to adjust the flow rate. This adjustment method is simple and can realize the stepless adjustment of the flow rate, but it is difficult to accurately measure the flow rate, and it is necessary to perform multiple adjustments to achieve the desired value. The regulation of the flow is more dependent on the operator's experience than the flow regulator itself. It cannot be applied when precise control of flow rate regulation is required.
在需要精確控制輸液流速時，普遍使用輸液泵，但是輸液泵價格高昂，不利推廣且操作過於複雜，不夠直觀簡便，尤其是在普通病人病情急變時，需費時安裝調試方可投入應用。Infusion pumps are commonly used when precise control of infusion flow rate is required, but infusion pumps are expensive, unfavorable to promote and complicated to operate, not intuitive and simple, especially when the patient's condition is rapidly changing, and it takes time and effort to install and debug.

當流速調節通道設置於流速調節板時，液體通過進液口進入主槽，之後依次通過調速凹槽和密封墊上的通孔進入出液口；類似地，當流速調節通道設置於固定底座時，液體通過進液口依次進入密封墊上的通孔和進入調速凹槽，接著進入主槽，最終通過出液口流出。When the flow rate adjusting passage is disposed on the flow rate adjusting plate, the liquid enters the main groove through the liquid inlet, and then enters the liquid outlet through the through hole of the speed regulating groove and the sealing block; similarly, when the flow rate adjusting channel is set on the fixed base The liquid enters the through hole on the gasket through the liquid inlet and enters the speed control groove, then enters the main groove, and finally flows out through the liquid outlet.
如第11圖所示，由主槽和調速凹槽共同構成的流速調節通道也可以是一條環形的凹槽C1，該凹槽的橫截面積依次變小，與進液口或出液口相連的尾端C的橫截面積最大。這樣凹槽轉動時，凹槽與出口之間的橫截面積也隨之變化，實現對流速的調節。As shown in Fig. 11, the flow rate adjusting passage formed by the main groove and the speed regulating groove may also be an annular groove C1, and the cross-sectional area of the groove is successively smaller, and the liquid inlet or the liquid outlet The connected end C has the largest cross-sectional area. When the groove is rotated, the cross-sectional area between the groove and the outlet also changes, and the flow rate is adjusted.
較佳地，上述調節器中，流速調節板2和固定底座1中的至少一個設有至少一個滅菌用通孔22，滅菌用通孔較佳至少有兩個，其中一個用於輸入滅菌液(氣)，另外一個用於匯出入滅菌液(氣)。在組裝完畢後，滅菌用通孔處於封閉狀態。Preferably, in the regulator, at least one of the flow rate adjusting plate 2 and the fixed base 1 is provided with at least one through hole 22 for sterilization, and at least two through holes for sterilization are preferably used for inputting the sterilization liquid ( Gas), the other is used to recirculate the sterilizing liquid (gas).

當液流通道為間隔分佈的凹槽或流速調節通道採用間隔式調速凹槽時，凹槽具有不同的孔徑(橫截面積)。較佳地，凹槽為徑向分佈，不同的凹槽的長度相同。特別地，相鄰的凹槽的最小橫截面積朝一個方向依次增大，如由左至右依次增大，這樣在進行流速調節時，可以使流速順次增大或減小，方便調節流速；這些間隔的凹槽既可以單獨作為液流通道調節流速，也可以是多個凹槽共同組合形成液流通道，這樣可以更為精確的調節液流通道的面積，對流速進行更為精確的調節。凹槽的橫截面可以是矩形、半圓形、管狀或其他形狀。The grooves have different apertures (cross-sectional areas) when the flow channels are spaced-apart grooves or the flow rate adjustment channels are spaced-available. Preferably, the grooves are radially distributed and the different grooves have the same length. In particular, the minimum cross-sectional area of adjacent grooves sequentially increases in one direction, such as from left to right, so that when the flow rate is adjusted, the flow rate can be sequentially increased or decreased to facilitate the adjustment of the flow rate; These spaced grooves can be used as a liquid flow channel to adjust the flow rate alone, or a plurality of grooves can be combined to form a liquid flow channel, which can more precisely adjust the area of the liquid flow channel and more precisely adjust the flow rate. . The cross section of the groove can be rectangular, semi-circular, tubular or other shape.
當液流通道為橫截面積連續變化的凹槽或流速調節通道採用環形調速凹槽時，凹槽較佳為圓弧形。液流通道或環形調速凹槽也可以由多條凹槽共同組成，這些凹槽彼此間共圓心。這種情況下，液流通道的橫截面積為多條凹槽的總橫截面積。當凹槽移動時，其與密封墊之間的橫截面積也隨之變化，進而控制流速。橫截面積較佳沿一個方向連續增大或減小，方便使流速相應地連續增大或減小。凹槽的橫截面可以是矩形、半圓形或其他半封閉形狀。When the liquid flow path is a groove in which the cross-sectional area continuously changes or the flow velocity adjustment passage adopts a ring-shaped speed control groove, the groove is preferably a circular arc shape. The flow channel or the annular velocity regulating groove may also be composed of a plurality of grooves which are concentric with each other. In this case, the cross-sectional area of the flow passage is the total cross-sectional area of the plurality of grooves. When the groove moves, its horizontal relationship with the gasketThe cross-sectional area also changes, which in turn controls the flow rate. The cross-sectional area is preferably continuously increased or decreased in one direction, so that the flow rate is continuously increased or decreased correspondingly. The cross section of the groove can be rectangular, semi-circular or other semi-closed shape.
較佳地，上述調節器中，固定底座1向外延伸有定位底盤13，流速調節板2向外延伸有定位動盤23，定位底盤13和定位動盤23之間設有定位塊24。Preferably, in the adjuster, the fixed base 1 has a positioning chassis 13 extending outwardly, and the flow rate adjusting plate 2 extends outwardly with a positioning movable plate 23, and a positioning block 24 is disposed between the positioning chassis 13 and the positioning movable plate 23.
定位塊可以是相互配合的定位凸起和定位凹槽，特別地，定位塊為相互配合的半球狀凸起和半球狀凹陷。定位塊較佳有多組。定位塊的設置可以指示調速是否到位，方便流速的設定，避免調節時出現失誤，影響輸液的進程。定位塊的設置還可以保證在設定流速後，不會輕易變化，導致流速漂移。The positioning block may be a matching positioning protrusion and a positioning groove, and in particular, the positioning block is a hemispherical protrusion and a hemispherical depression which cooperate with each other.
