Description

醫療用導管控制閥Medical catheter control valve

本發明係有關一種醫療用導管控制閥,尤指一種實施於醫療器材流體導管上之控制閥,如輸血管或藥液注射管,可單手控制流體流通或停止之控制閥設計。The invention relates to a medical catheter control valve, in particular to a control valve implemented on a fluid conduit of a medical device, such as a blood vessel or a liquid medicine injection tube, and a control valve design capable of controlling fluid circulation or stopping with one hand.

按,醫療機構通常所使用如輸血及注射之管件,為使能將血液或注射液輸至病患或自病患身體輸出收集,均會於管件上設有一控制裝置,特別於手術室中使用時,為使能於手術中操作方便,故需有一可單手操作且操作簡便之控制閥。According to the regulations, such as blood transfusion and injection, commonly used in medical institutions, in order to enable blood or injection to be delivered to the patient or to be collected from the patient's body, a control device is provided on the tube, especially in the operating room. In order to facilitate the operation during surgery, it is necessary to have a control valve that can be operated with one hand and is easy to operate.

而習知之設計,如第九圖及第十圖所示,其主要係於控制閥(7)之通道(71)內穿設有一軟管(72),並於控制閥(7)上,設有一受推移件(8)控制之壓柱(82),推移件(8)下方設有一斜面(81),當推移該推移件(8)使其下方斜面(81)將壓柱(82)下推進入控制閥(7)內將內部之軟管(72)擠壓變形而產生封閉,進而達到阻斷流體通過之目的。The conventional design, as shown in the ninth and tenth figures, is mainly provided with a hose (72) in the passage (71) of the control valve (7), and is provided on the control valve (7). There is a pressing column (82) controlled by the pushing member (8), and a slope (81) is arranged under the pushing member (8). When the pushing member (8) is pushed, the lower inclined surface (81) is pressed under the pressing column (82). Pushing into the control valve (7), the inner hose (72) is pressed and deformed to form a seal, thereby blocking the passage of the fluid.

但習知之設計,其軟管(72)係設於控制閥(7)之內孔,其受擠壓時,軟管(72)雖被擠壓變形,但向兩側膨脹,但因被控制閥(7)內孔空間限制,而使軟管(72)之左右膨脹空間受到限制,進而無法使軟管被完全擠壓封閉,而均會產生一間隙(A),而無法完全阻止流體通過,進而對手術醫療造成影響。However, the conventional design has a hose (72) which is provided in the inner hole of the control valve (7). When it is squeezed, the hose (72) is squeezed and deformed, but expands to both sides, but is controlled The inner space of the valve (7) is limited, and the left and right expansion space of the hose (72) is restricted, so that the hose cannot be completely squeezed and closed, and a gap (A) is generated, and the fluid cannot be completely prevented from passing through. And thus affect the surgical treatment.
