免針筒式指尖負壓採血器Needleless fingertip negative pressure blood collection device
本創作係有關於一種採血器，尤指一種免針筒式指尖負壓採血器。This creation is about a blood collection device, especially a needle-free negative finger pressure blood collection device.
實驗室測試中所用血樣經常籍由將皮下注射針頭刺入對象靜脈中之靜脈穿刺採得。皮下注射針頭所抽出之血液可被直接吸入注射器或者一個或多個密封小瓶中，以供後繼處理使用。當靜脈穿刺難以或無法實施，諸如對於新生兒等情形，可採用足跟穿刺或其它部位穿刺等非靜脈穿刺採集血樣供測試。所採集之血樣通常經封裝、傳遞至處理中心以供分析。 傳統用途之穿刺裝置，其通常具有一剛性本體及一自一端突起的無菌針。穿刺裝置可以用於穿透皮膚，以便能夠從該開口收集血液樣本。然後，血液傳送至一測試收集裝置。血液最常取自於指尖。舉例而言，藉由此系統，特別是在醫院之環境中，通常穿刺一病患，經由毛細作用收集血液樣本於微移液管中，然後自移液管輸送血液樣本至測試收集裝置。 然而，習用穿刺裝置具有缺陷。舉例而言，最基礎之測試除外，當前可用之血液測試通常須要求從對象抽取相當大量之血液。因須要大量之血液，經常不採用從痛苦較少和/或侵入較少之替用部位抽取血樣，如耳垂，蓋因其無法產出習用穿刺裝置所需之血液量。而指尖中安置有大量之小血管，所以在該處通常有豐富之血液供應量，惟指尖之曲線形表面需施加正確數量之壓力，才能從病患快速及有效地擷取體積足夠之血液，但因指尖於皮下組織具有大量神經末梢，抽血過程中容易對病患造成顯著的疼痛，且對於一些慢性病患，例如糖尿病患者經常都需要抽血作測試更是苦不堪言，其指尖重複穿刺會產生皮膚角質化或是導致形成繭，結果造成抽血時必須刺入更深之部位而產生更疼痛感。在某些情形下，因指尖穿刺引起之病患顧慮可使病患不遵守測試方案。故，ㄧ般習用者係無法符合使用者於實際使用時之所需。Blood samples used in laboratory tests are often obtained by venipuncture of a hypodermic needle into a subject's vein. Blood drawn from a hypodermic needle can be drawn directly into a syringe or one or more sealed vials for subsequent processing. When venipuncture is difficult or impossible, such as for newborns, a non-venous puncture such as heel puncture or other site puncture can be used to collect blood samples for testing. Collected blood samples are usually packaged and transferred to a processing center for analysis. Conventional puncture devices usually have a rigid body and a sterile needle protruding from one end. The puncture device can be used to penetrate the skin so that a blood sample can be collected from the opening. The blood is then transferred to a test collection device. Blood is most often taken from the fingertips. For example, with this system, especially in a hospital environment, a patient is usually punctured, a blood sample is collected in a micropipette via capillary action, and then a blood sample is delivered from the pipette to a test collection device. However, conventional puncturing devices have drawbacks. For example, with the exception of the most basic tests, currently available blood tests usually require a substantial amount of blood to be drawn from the subject. Because a large amount of blood is required, blood samples are often not taken from alternative sites that are less painful and / or less invasive, such as earlobe, and Gein cannot produce the amount of blood needed for conventional puncture devices. There are a large number of small blood vessels in the fingertips, so there is usually ample blood supply there, but the curved surface of the fingertips needs to apply the correct amount of pressure in order to quickly and effectively retrieve a sufficient volume from the patient. Blood, but because the fingertips have a large number of nerve endings in the subcutaneous tissue, it is easy to cause significant pain to the patient during blood drawing, and for some chronic patients, such as diabetic patients, it is often difficult to take blood for testing, Repeated puncture of the fingertips can cause keratinization of the skin or cause cocoon formation. As a result, deeper parts must be penetrated when blood is drawn, resulting in more pain. In some cases, patient concerns caused by fingertip punctures can prevent patients from following the test protocol. Therefore, ordinary users cannot meet the needs of users in actual use.
