Abstract
Description
本新型創作是有關於一種採血器。This new creation is about a blood collection device.
近來，隨著醫學技術的不斷發展，通過驗血診斷各種疾病的技術已相當發達，其結果在診斷各種疾病時經常要求驗血。根據不同的疾病，血液檢驗包括：生化檢驗、血清免疫檢驗以及血球檢驗等，但主要是實施血清檢驗。在進行血液檢驗時，檢驗所需的血清來自血液，而該血液是通過採血裝置從人體而採得。採得的血液通過離心分離器的處理過程而分離成血清和凝血（由血球和血纖維的混合物形成的凝膠狀物質），檢驗人員則分離出血清後進行有關的檢驗工作。Recently, with the continuous development of medical technology, techniques for diagnosing various diseases by blood tests have been quite developed, and as a result, blood tests are often required in the diagnosis of various diseases. According to different diseases, blood tests include: biochemical tests, serum immunoassays, and blood cell tests, but mainly for the implementation of serum tests. In the blood test, the serum required for the test is from the blood, and the blood is taken from the human body by the blood collection device. The collected blood is separated into serum and coagulation (gel-like substance formed by a mixture of blood cells and blood fibers) by a centrifugal separator process, and the examiner separates the serum and performs related inspection work.
目前，雖然有多種採血裝置，但近來主要採用由一次性注射器、固定器及特殊針頭構成的真空採血管，即主要採用通過壓力差而採血的方法。At present, although there are various blood collection devices, a vacuum blood collection tube composed of a disposable syringe, a holder, and a special needle has recently been mainly used, that is, a method of collecting blood by a pressure difference is mainly employed.
本新型創作提供一種採血管，藉由其內的攪拌軸而受注入管內的血液驅動而旋轉以達到攪拌血液的效果。The novel creation provides a blood collection tube that is driven by blood in the injection tube to rotate by the agitating shaft therein to achieve the effect of stirring blood.
本新型創作的採血管，適用於真空採血裝置。採血管包括管體、蓋體與攪拌軸。蓋體組裝於管體而形成封閉空間。蓋體適於可拆卸地組裝於真空採血裝置。攪拌軸自由樞接於管體與蓋體的至少其一，而位於封閉空間，其中當血液經由真空採血裝置採集而進入封閉空間時，攪拌軸受血液驅動而旋轉並攪拌血液。The blood collection tube created by the novel is suitable for a vacuum blood collection device. The blood collection tube includes a tube body, a lid body and a stirring shaft. The cover body is assembled to the tubular body to form an enclosed space. The cover is adapted to be detachably assembled to a vacuum blood collection device. The agitating shaft is freely pivotally connected to at least one of the tube body and the lid body, and is located in the closed space, wherein when the blood is collected through the vacuum blood collecting device and enters the closed space, the stirring shaft is driven by the blood to rotate and stir the blood.
基於上述，藉由在採血管內設置能自由樞轉的攪拌軸，因而當血液被真空採血裝置採集而注入採血管時，即能驅動攪拌軸旋轉，因而造成血液能被攪拌軸進行攪拌的效果，進而避免採血管因人為疏失而發生未搖晃而容易產生凝結的情形。Based on the above, by providing a stirring shaft that can pivot freely in the blood collection tube, when the blood is collected by the vacuum blood collection device and injected into the blood collection tube, the stirring shaft can be driven to rotate, thereby causing the blood to be stirred by the stirring shaft. In addition, the blood collection tube is prevented from being clogged by the human being due to human error.
為讓本新型創作的上述特徵和優點能更明顯易懂，下文特舉實施例，並配合所附圖式作詳細說明如下。The above described features and advantages of the present invention will become more apparent and understood from the following description.
圖1是依據本新型創作一實施例的採血管的***圖。請參考圖1，在本實施例中，採血管100包括管體120、蓋體130以及攪拌軸110，其中蓋體130組裝於管體120而形成封閉空間，攪拌軸110自由樞接於管體120與蓋體130的至少其一，而位於所述封閉空間。此時，當採血管未被使用時，所述封閉空間實質為真空。1 is an exploded view of a blood collection tube in accordance with an embodiment of the present invention. Referring to FIG. 1 , in the embodiment, the blood collection tube 100 includes a tube body 120 , a lid body 130 , and a stirring shaft 110 . The lid body 130 is assembled to the tube body 120 to form a closed space, and the agitating shaft 110 is freely pivoted to the tube body. 120 and at least one of the cover bodies 130 are located in the enclosed space. At this time, when the blood collection tube is not used, the closed space is substantially vacuum.
圖2是圖1的採血管應用於真空採血裝置的簡單示意圖。請同時參考圖1與圖2，在本實施例中，採血管100適於藉由蓋體130而可拆卸地組裝於真空採血裝置200，亦即，當真空採血裝置200進行採血動作時，採血管100可在血液採集完成後進行更換（前一採血管100注滿血液後可從真空採血裝置200卸除，並裝上另一未使用的採血管100），而達到能接續採血且不中斷的效果。同時，未使用前的採血管100的封閉空間實質為真空，而有利於當真空採血裝置200的針頭***血管時，血管內的血液由於壓力差而通過針頭流入到採血管100內。2 is a simplified schematic view of the blood collection tube of FIG. 1 applied to a vacuum blood collection device. Referring to FIG. 1 and FIG. 2 simultaneously, in the present embodiment, the blood collection tube 100 is adapted to be detachably assembled to the vacuum blood collection device 200 by the cover 130, that is, when the vacuum blood collection device 200 performs a blood collection operation, The blood vessel 100 can be replaced after the blood collection is completed (the first blood collection tube 100 can be removed from the vacuum blood collection device 200 after being filled with blood, and another unused blood collection tube 100 is installed), and the blood collection can be continued without interruption. Effect. At the same time, the closed space of the blood collection tube 100 before use is substantially vacuum, and when the needle of the vacuum blood collection device 200 is inserted into the blood vessel, the blood in the blood vessel flows into the blood collection tube 100 through the needle due to the pressure difference.
再者，蓋體130還具有通道與逆止結構（未繪示），採血管組裝至真空採血裝置200時，便能驅動逆止結構而使通道開啟，以利於讓血液經由通道注入管體120。當採到一定量的血液而把真空採血裝置200的針頭抽出血管後，即能因所述逆止結構而使蓋體130的通道密合，從而使採血管100的封閉空間與外部環境隔絕，而達到防止空氣流入或血液流出之狀態。惟，所述通道與逆止結構已能由現有技術得知，故在此毋須贅述。Furthermore, the cover body 130 also has a passage and a backstop structure (not shown). When the blood collection tube is assembled to the vacuum blood collection device 200, the backstop structure can be driven to open the channel to facilitate the injection of blood into the tube body 120 through the channel. . When a certain amount of blood is taken and the needle of the vacuum blood collection device 200 is withdrawn from the blood vessel, the passage of the cover 130 can be closed by the backstop structure, thereby isolating the enclosed space of the blood collection tube 100 from the external environment. It is in a state of preventing the inflow of air or the outflow of blood. However, the passage and the reverse stop structure can be known from the prior art, and therefore need not be described here.
值得注意的是，由於攪拌軸110是自由樞接於封閉空間中，在此繪示攪拌軸110的第一端E1自由樞接于蓋體130，而第二端E2自由樞接於管體120的底部，因此攪拌軸110能以軸心L1進行自由樞轉（但不以此為限，攪拌軸110僅以第一端E1或第二端E2樞接時，同樣能達到樞轉效果），亦即當血液經由真空採血裝置200的採集而注入採血管100時，血液進入封閉空間的同時便會驅動攪拌軸110以軸心L1旋轉，如此一來，在封閉空間中的攪拌軸110便能提供血液攪拌的效果。It is noted that the first end E1 of the agitating shaft 110 is freely pivotally connected to the cover body 130, and the second end E2 is freely pivotally connected to the tubular body 120, because the agitating shaft 110 is freely pivoted in the closed space. Therefore, the agitating shaft 110 can be freely pivoted by the axis L1 (but not limited thereto, the pivoting effect can also be achieved when the agitating shaft 110 is only pivoted by the first end E1 or the second end E2), That is, when the blood is injected into the blood collection tube 100 through the collection of the vacuum blood collection device 200, the blood enters the closed space and the stirring shaft 110 is driven to rotate with the axis L1, so that the stirring shaft 110 in the closed space can be Provides the effect of blood agitation.
詳細而言，攪拌軸110具有環繞軸心L1的螺旋溝槽，且所述溝槽實質上面對蓋體130設置，也就是說，當血液注入封閉空間時，便存在較大機率而衝擊攪拌軸110的螺旋溝槽，進而讓血液注入封閉空間的動力能據以成為攪拌軸110以軸心L1旋轉的動力。據此，螺旋溝槽在靠近蓋體130處（即鄰近第一端E1處）具有較大的螺旋半徑，而在靠近管體120底部處（即鄰近第二端E2處）則具有較小螺旋半徑，因而在從蓋體130朝向管體120底部的方向上，螺旋溝槽是呈現朝向軸心L1收斂的輪廓，據以讓血液在剛注入管體120時（具有較大動力時）即能衝擊螺旋溝槽而提供攪拌軸110足夠的旋轉動力。In detail, the agitating shaft 110 has a spiral groove surrounding the axis L1, and the groove is substantially disposed facing the cover 130, that is, when blood is injected into the closed space, there is a large probability of impact stirring. The spiral groove of the shaft 110, which in turn allows the power of the blood to be injected into the enclosed space, to be the power for the agitator shaft 110 to rotate with the axis L1. Accordingly, the spiral groove has a larger spiral radius near the cover 130 (ie, adjacent to the first end E1) and a smaller spiral near the bottom of the tubular body 120 (ie, adjacent to the second end E2). The radius, thus in the direction from the cover 130 toward the bottom of the tubular body 120, the spiral groove presents a contour that converges toward the axis L1, so that the blood can be injected into the tubular body 120 (when there is greater power) The spiral groove is impacted to provide sufficient rotational power of the agitator shaft 110.
再者，在本實施例中，管體120的內部或/及攪拌軸110的表面還塗佈有抗凝血劑，因此當攪拌軸110受血液驅動而以軸心L1旋轉並對血液造成攪拌效果時，即能有效地將抗凝血劑與血液進行充分地混合。如此一來，將能因攪拌軸110受血液驅動的旋轉運動，而讓操作者即使忘了搖晃採血管100，仍能使採集的血液與抗凝血劑順利混合，而克服可能的人為疏失。Furthermore, in the present embodiment, the inside of the tubular body 120 or/and the surface of the agitating shaft 110 are also coated with an anticoagulant, so that when the agitating shaft 110 is driven by blood, it rotates with the axis L1 and causes agitation of the blood. When the effect is achieved, the anticoagulant can be effectively mixed with the blood. In this way, due to the rotational movement of the agitator shaft 110 by the blood, the operator can smoothly mix the collected blood and the anticoagulant even if he forgets to shake the blood collection tube 100, thereby overcoming possible human error.
圖3是本新型創作另一實施例的採血管的局部示意圖。請參考圖3，與前述實施例不同的是，本實施例的攪拌軸320上的螺旋溝槽是具有一致的螺旋半徑，也就是說，異於前述實施例的攪拌軸110是呈圓錐體，本實施例的攪拌軸320則是呈現圓柱體，然當血液注入採血管時，其仍能因與攪拌軸320上的螺旋溝槽衝擊，而據以驅動攪拌軸320以軸心L2進行旋轉，同樣能達到攪拌血液的效果。3 is a partial schematic view of a blood collection tube of another embodiment of the present invention. Referring to FIG. 3, unlike the foregoing embodiment, the spiral groove on the agitating shaft 320 of the present embodiment has a uniform spiral radius, that is, the agitating shaft 110 different from the foregoing embodiment is a cone. The agitating shaft 320 of the present embodiment is a cylindrical body. However, when the blood is injected into the blood collecting tube, it can still be rotated by the spiral groove on the stirring shaft 320, thereby driving the stirring shaft 320 to rotate with the axis L2. The same effect can be achieved by stirring the blood.
綜上所述，在本新型創作的上述實施例中，藉由在採血管內設置能自由樞轉的攪拌軸，因而當血液被真空採血裝置採集而注入採血管時，即能驅動攪拌軸旋轉，因而造成血液能被攪拌軸進行攪拌的效果，進而避免採血管因人為疏失而發生未搖晃而容易產生凝結的情形。In summary, in the above embodiment of the present invention, by providing a freely pivotable agitating shaft in the blood collection tube, when the blood is collected by the vacuum blood collection device and injected into the blood collection tube, the stirring shaft can be driven to rotate. Therefore, the blood can be stirred by the stirring shaft, thereby avoiding the situation that the blood collection tube is easily shaken due to human error and is not swayed.
進一步地說，由於攪拌軸的表面設置有螺旋溝槽，而使注入封閉空間的血液能與螺旋溝槽產生衝擊並據以提供驅動攪拌軸旋轉的動力，在一實施例中，所述螺旋溝槽具有朝向軸心收斂的輪廓，而在另一實施例中，螺旋溝槽具有一致的螺旋半徑，其皆能讓注入的血液據以驅動攪拌軸沿軸心旋轉，而達到所需的攪拌效果。Further, since the surface of the agitating shaft is provided with a spiral groove, the blood injected into the closed space can be impacted with the spiral groove and accordingly provide power for driving the rotation of the stirring shaft. In an embodiment, the spiral groove The groove has a contour that converges toward the axis, while in another embodiment, the spiral groove has a uniform radius of helix, which allows the injected blood to drive the agitator shaft to rotate along the axis to achieve the desired agitation effect. .
雖然本新型創作已以實施例揭露如上，然其並非用以限定本新型創作，任何所屬技術領域中具有通常知識者，在不脫離本新型創作的精神和範圍內，當可作些許的更動與潤飾，故本新型創作的保護範圍當視後附的申請專利範圍所界定者為準。Although the present invention has been disclosed in the above embodiments, it is not intended to limit the novel creation, and any person skilled in the art can make some changes without departing from the spirit and scope of the novel creation. Retouching, the scope of protection of this new creation is subject to the definition of the scope of the patent application attached.
