201103500 九、發明說明： 【發明所屬之技術領域】 本發明係有關於一種使用於醫院、防止血液交叉感染的一次性採血裝 置，尤指一種能利用將採血針高速刺進皮膚以減少疼痛，以及可調整刺進 皮膚深淺以利不同部位採血的裝置。 【先前技術】 Φ 比較輕巧便宜而普遍採用的採血裝置一般分成兩種。一種是將一次性 使用的採血針（lancet)裝在採血筆（lancingdevice)裡面，用完之後再將使 用過的採血針丟棄，換上新的採血針。這種採血方式個人自己使用可以， 醫院一般不採用，因為採血筆的頭採血時有可能會沾到血跡而將疾病感染 給不同患者。所以，為了防止交叉感染，醫院通常會使用一次14的安全採 血針筆（safety lancet)。但是，目前所有的一次性的安全採血針筆都用簡單 的彈簧結構，導致患者採血時疼痛不已。同時，隨著越來越多的血糖檢測 φ 試片能使用指尖血以外部位（如手臂採血）所採集的血作血糖測試，傳統 的一次性安全採血針筆沒辦法調整採血針進人皮膚的深淺，只能做指尖採 血，作手臂採血雖然比較不痛，但是無法調整採血針進人皮膚深一點，所 以不容易採到適當的血量。本發明專利就是為了克服這個缺點設計而成。 它不但能調整採血針進入皮膚的深淺以利不同部位採血，也能以高速將採 血針刺入皮膚以減少疼痛感，而且它只能一次使用，用完就失效，不能第 二次使用。 5 201103500 【發明內容】 本發明是有關於一種能利用撞擊原理將採血針高速刺進皮膚以減少疼 痛，以及可調整刺進皮膚深淺以利不同部位採血的裝置。本創作之上述及 其他目的與優點，可從下述圖中，獲得深人了解。 【實施方式】 如第一圖及第二圖所示，一個圓形上蓋中空體1，内置有一已壓縮的上 彈簧2及一撞擊塊3，而此圓形上蓋中空體1有一圓型開□ 可讓已壓縮 的上彈簧2將撞擊塊3以一定速度射出。圓形上蓋中空體1可為塑膠或橡 膠材質’而撞擊塊3可為金屬、陶瓷或塑膠材質，但必須比採血針座4重。 此圓形上蓋中空體1又與一外殼6相連接，而此外殼6内置有一採血針座4〇 較重的撞擊塊3以低速撞擊較輕的採血針座4，使得較輕的採血針座4能以 較高速度射出。外殼6上設有一凸塊20與包覆其上的外筒7的斜開口 30 相崁人。因此，當外殼6與外筒7之間旋轉一些角度時，此採血針筆可以 具有調整採血針刺入皮膚深淺的功能，以利於調整較淺的手指採血或較深 的手臂採血。 第一圖所示的圓形上蓋中空體1内置有一已壓縮的上彈簧2及一撞擊塊 3。已壓縮的上彈簧2有彈力欲把撞擊塊3往圓形上蓋中空體1的圓型開口 10推出，但是由於圓型開口 10的直徑較撞擊塊3的上緣11的直徑小，所 以藉由橡膠或塑膠材料的彈性該圓形上蓋中空體1能將已壓縮的上彈簧2 及一撞擊塊3限制在該圓形上蓋中空體1内。要使用本發明所揭示的採血 針筆時，必須先把連接於採血針座4上的針套14移除，露出採血針15，然 201103500 後由圓形上蓋中空體1上方出力往下壓，如第三圖所示。當撞擊塊3受來 自圓形上蓋中空體1上方壓擠而使得撞擊塊3的上緣11要通過圓形上蓋中 空體1的圓型開口 10時，圓形上蓋中空體1於圚型開口 10的凸環16會往 下擴張變形使得撞擊塊3的上緣11能通過圓形上蓋中空體1的圓型開口 10,因而圓形上蓋中空體1内置的已壓縮的上彈簧2會將撞擊塊3向下快速 推出去撞擊採血針座4。由於撞擊塊3的重量大於採血針座4，所以，被撞 的採血針座4會以比撞擊塊3更高的速度往下運動。而被撞的採血針座4 上兩側各有一外凸條17 (如第四圖所示）崁入並沿著外殼6內側的兩條内 凹槽18 (如第五圖所示）往下行進，直到採血針座4下方的斜條19碰到外 殼6內側下方的內斜面21時停止（如第六圖所示），而此時下彈簧5會先被 採血針座4壓縮後再將採血針座4往上推（如第七圖所示）。在第六圖中， 採血針座4下方採血針15突出於外筒7下方的開孔22的長度就是採血針 15刺進皮膚的深度。 夕卜殻6上設有一凸塊20與包覆其上的外筒7的斜開口 30相崁人使得 外殼6與外筒7可以相互旋轉並根據凸塊20與斜開口 30的相對位置來決定 採血針15刺進皮膚的深度’如第八圖所示。最左邊的採血針丨5刺進皮膚的 深度最淺，而最右邊的採血針15刺進皮膚的深度最深。 本專利的另一種設計是如第九圖及第十圖所示。它包含有一個圓形上 蓋中空體1 ’内置有一已壓縮的上彈簧2及一與上彈簧2相銜接的採血針座 4,而此圓形上蓋中空體有一圓型開口 1〇可讓已壓縮的上彈賽2將採血針座 4射出並拉回。此圓形上蓋中空體1又與一外殻6相連接。外殼6上設有— 201103500 凸塊20與包覆其上的外筒7的斜開口 30相崁人。因此，當外殻6與外筒7 之間旋轉一些角度時，此採血針筆可以具有調整採血針刺入皮膚深淺的功 能，以利於調整較淺的手指採血或較深的手臂採血。 第九及第十圖所示的圓形上蓋中空體1内置有一已壓縮的上彈簧2 及固定一採血針座4。該圓形上蓋中空體1内側上方有一圓型固定環23 扣住上彈簧2，而採血針座4的上端亦設有一圓型固定環23扣住上彈簧 2。已壓縮的上彈簧2有彈力欲把採血針座4往圓形上蓋中空體1的圓 型開□ 10推出，但是由於圓型開口 10的直徑較採血針座4的上緣11 的直徑小，所以藉由橡膠或塑膠材質的彈性該圓形上蓋中空體1能將已 壓縮的上彈簧2及採血針座4限制在該圓形上蓋中空體1上。要使用本 發明所揭示的採血針筆時，必須先把連接於採血針座4上的針套14移 除，露出採血針15，然後由圓形上蓋中空體1上方出力往下壓，如第十 一圖所示。當採血針座4受來自圓形上蓋中空體1上方壓擠而使得採血 針座4的上緣11要通過圓形上蓋中空體1的圓型開口 1〇時，圓形上蓋 中空體1於圓型開口 10的凸環16會往下擴張便行使得採血針座4的上 緣11能通過圓形上蓋中空體1的圓型開口 10，因而圓形上蓋中空體1 內置的已壓縮的上彈簧2會將採血針座4向下快速推出去。採血針座4 上方設有一圓型固定環23以固定住上彈簧2。採血針座4上兩側各有一 外凸條17 (如第十圖所示）崁人並沿著外殼6內側的兩條內凹槽18 (如 第五圖所示）往下行進，直到採血針座4下方的斜條19碰到外殻6内 側下方的内斜面21時停止（如第十二圖所示），而此時上彈簧2會將採 201103500 血針座4拉回（如第十二圖所示）。在第十二圖中，採血針座4下方採 血針15突出於外筒7下方的開孔22的長度就是採血針15刺進皮膚的深 度。 夕卜殻6上設有一凸塊20與包覆其上的外筒7的斜開□ 3〇相崁入使得 外殼6與外筒7可以相互旋轉並根據凸塊2〇與斜開口 3〇的相對位置來決定 採血針15刺進皮膚的深度，如第十四圖所示。最左邊的採血針15刺進皮膚 的深度最淺’而最右邊的採血針15刺進皮膚的深度最深。 本專利的又另一種設計是如第十五到第十七圖所示。它包含有一個圓形 上蓋中空體1，内置有一已壓縮的上彈簧2及一撞擊塊3，而此撞擊塊3的 上緣11有一斜面與外殼6内徑上方的三個或四個凸柱31的斜面些接觸。圓 形上蓋中空體1可為塑膠或橡膠材質，而撞擊塊3可為金屬、陶瓷或塑膠 材質’但必須比採血針座4重。此圓形上蓋中空體1又與一外殼6相連接， 而此外殼6内置有一採血針座4。較重的撞擊塊3以低速撞擊較輕的採血針 座4 ’使得較輕的採血針座4能以較高速度射出。外殼6上設有一凸塊20 與包覆其上的外筒7的斜開口 30相崁入。因此，當外殼6與外筒7之間旋 轉一些角度時，此採血針筆可以具有調整採血針刺人皮膚深淺的功能，以 利於調整較淺的手指採血或較深的手臂採血。 第十五圖所示的圓形上蓋中空體1内置有一已壓縮的上彈簧2及一撞擊 塊3。已壓縮的上彈簧2有彈力欲把撞擊塊3藉由撞擊塊3的上緣11將凸 柱31往外變型之際往下推出。要使用本發明所揭示的採血針筆時，必須先 把連接於採血針座4上的針套14移除，露出採血針15，然後由圓形上蓋中 201103500 空體1上方出力往下壓。當撞擊塊3受來自圓形上蓋中空體1上方壓擠而 使得撞擊塊3的上緣11的斜面要迫使凸柱31往外變形讓撞擊塊3通過凸柱 31，因而圓形上蓋中空體1內置的已壓缩的上彈簧2會將撞擊塊3向下快速 推出去撞擊採血針座4。由於撞擊塊3的重量大於採血針座4，所以，被撞 的採血針座4會以比撞擊塊3更高的速度往下運動。而被撞的採血針座4 上兩側各有一外凸條17 (如第四圖所示）崁人並沿著外殼6内側的兩條内 凹槽18 (如第五圖所示）往下行進，直到採血針座4下方的斜條19碰到外 殼6内側下方的内斜面21時停止（如第六圖所示），而此時下彈簧5會先被 採血針座4壓縮後再將採血針座4往上推（如第七圖所示）。在第六圖中， 採血針座4下方採血針15突出於外筒7下方的開孔22的長度就是採血針 15刺進皮膚的深度。 外殻6上設有一凸塊20與包覆其上的外筒7的斜開口 30相崁人使得 外殼6與外筒7可以相互旋轉並根據凸塊20與斜開口 30的相對位置來決定 採血針15刺進皮膚的深度，如第八圖所示。最左邊的採血針15刺進皮膚的 深度最淺’而最右邊的採血針15刺進皮膚的深度最深。 第十五到第十七圖所揭示之設計的外殼6與外筒7與第一圖的外殼6 與外筒7有所不同，其中外筒7的斜開口 30上方有數個凹齒36與外殻6 上的凸塊20接觸’以防止當上蓋中空體1上方受到壓擠時，外殼6與外筒 7之間會有相互運動。同時外筒7的内徑也設有數個内凹條34與外殼6上 的微凸塊35接觸’以防止當上蓋中空體丨上方受到壓濟時，外殻6與外筒 7之間會有相互運動。 201103500 由以上詳細說明’可使熟知本項技藝者明瞭本創作的確可達成前述目 的’實已符合專利法之規定，爰提出專利申請。 惟以上所述者’僅為本創作之較佳實施例而已，當不能以此限定本創作 實施之範圍；故’凡依本創作申請專利範圍及創作說明書內容所作之簡單 的等效變化與修飾，皆應仍屬本創作專利涵蓋之範圍内。 【圖式簡單說明】 Φ 第一圖，係含有撞擊塊的採血針筆的剖面示意圖 第二圖，係含有撞撃塊的採血針筆的零件示意圖 第三圖，係將含有撞擊塊的採血針筆由上方圓形上蓋中空體往下壓的剖面 示意圖 第四圖，係含有撞擊塊的採血針筆的採血針座零件示意圖 第五圖，係含有撞擊塊的採血針筆的外殼零件示意圖 第六圖，係將含有撞擊塊的採血針筆由上方圓形上蓋中空體往下壓而採血 • 針座到達底部的剖面示意圖 第七圖，係將含有撞擊塊的採血針筆由上方圓形上蓋中空體往下壓而採血 針座到達底部並被下彈簧往上推回的剖面示意圖 第八圖，係將含有撞擊塊的採血針筆由調整外殻與外筒相對位置使得採血 針能突出不同長度的剖面及外觀示意圖 第九圖，係不含有撞擊塊的採血針筆的剖面示意圖 第十圖，係不含有撞擊塊的採血針筆的零件示意圖 第十一圖，係將不含有撞擊塊的採血針筆由上方圓形上蓋中空體往下壓的 201103500 剖面示意圖 第十二圖，係將不含有撞擊塊的採血針筆由上方圓形上蓋中空體往下壓而 採血針座到達底部的剖面示意圖 第十三圖，係將不含有撞擊塊的採血針筆由上方橡皮中空體往下壓而採血 針座到達底部並被上彈簧往上拉回的剖面示意圖 第十四圖’係將不含有撞擊塊的採血針筆由調整外殼與外筒相對位置使得 採血針能突出不同長度的剖面及外觀示意圖 ® 第十五圖’係另一種含有撞擊塊的採血針筆的剖面示意圖 第十六圖’係另一種含有撞擊塊的採血針筆的零件示意圖 第十七圖’係第十六圖裡的第七號零件放大示意圖 【主要元件符號說明】 1. 圓形上蓋中空體 2. 上彈簧 • 3.撞擊塊 4：.採ώι針座 5. 下彈簧 6. 外殼 7. 外筒 10. 圓型開口 11. 上緣 14. 針套 15. 採血針 16. 凸環 17. 外凸條 12 201103500 18. 內凹槽 19. 斜條 20. 凸塊 21. 內斜面 22. 開孔 23. 圓型固定環 30. 斜開口 31. 凸柱 34. 內凹條 35. 微凸塊 36. 凹齒201103500 IX. Description of the Invention: [Technical Field] The present invention relates to a disposable blood collection device for use in a hospital to prevent cross-infection of blood, and more particularly to a method for using a blood collection needle to penetrate the skin at high speed to reduce pain, and It can adjust the depth of the skin to facilitate the blood collection in different parts. [Prior Art] Φ Lighter and cheaper blood-collecting devices are generally divided into two types. One is to put a disposable lancet in a lancing device. After use, discard the used lancet and replace it with a new lancet. This kind of blood collection method can be used by the individual, and the hospital generally does not use it, because the blood of the blood collection pen may be contaminated with blood to infect the disease to different patients. Therefore, in order to prevent cross-infection, hospitals usually use a 14 safety lancet. However, all current disposable safety lancets use a simple spring structure that causes pain in the patient's blood collection. At the same time, as more and more blood glucose test φ test strips can use blood collected from other parts of the fingertips (such as arm blood collection) for blood glucose test, the traditional disposable safety blood collection needle can't adjust the blood collection needle into the skin. The depth of the blood can only be used to collect blood from the fingertips. Although it is not painful to collect blood from the arm, it is impossible to adjust the blood collection needle into the skin, so it is not easy to get the proper blood volume. The invention patent is designed to overcome this disadvantage. It can not only adjust the depth of the blood collection needle into the skin to facilitate blood collection in different parts, but also can puncture the blood collection needle into the skin at high speed to reduce the pain, and it can only be used once, and it will be used up and will not be used for the second time. 5 201103500 SUMMARY OF THE INVENTION The present invention relates to a device capable of using a collision principle to puncture a blood collection needle into the skin at a high speed to reduce pain, and to adjust the depth of penetration into the skin to facilitate blood collection in different parts. The above and other objects and advantages of the present invention can be obtained from the following figures. [Embodiment] As shown in the first figure and the second figure, a circular upper cover hollow body 1 has a built-in compressed upper spring 2 and an impact block 3, and the circular upper cover hollow body 1 has a circular opening. The compressed upper spring 2 is allowed to eject the impact block 3 at a certain speed. The circular upper cover hollow body 1 may be a plastic or rubber material' and the impact block 3 may be made of metal, ceramic or plastic, but must be heavier than the blood collection needle holder 4. The circular upper cover hollow body 1 is in turn connected to a casing 6, and the outer casing 6 has a blood collection needle holder 4, and the heavier impact block 3 hits the lighter blood collection needle holder 4 at a low speed, so that the lighter blood collection needle holder is made. 4 can be shot at a higher speed. The outer casing 6 is provided with a projection 20 which is comparable to the oblique opening 30 of the outer cylinder 7 coated thereon. Therefore, when the outer casing 6 and the outer cylinder 7 are rotated at some angles, the lancet pen can have the function of adjusting the depth of penetration of the blood collection needle into the skin to facilitate adjustment of shallow finger blood collection or deep arm blood collection. The circular upper cover hollow body 1 shown in the first figure has a built-in compressed upper spring 2 and an impact block 3. The compressed upper spring 2 has an elastic force to push the impact block 3 toward the circular opening 10 of the circular upper cover hollow body 1, but since the diameter of the circular opening 10 is smaller than the diameter of the upper edge 11 of the impact block 3, Elasticity of the rubber or plastic material The circular upper cover hollow body 1 can restrain the compressed upper spring 2 and an impact block 3 in the circular upper cover hollow body 1. In order to use the blood collection needle disclosed in the present invention, the needle sleeve 14 connected to the blood collection needle holder 4 must first be removed to expose the blood collection needle 15, and after 201103500, the force is pressed downward from the upper hollow body 1 of the circular upper cover. As shown in the third figure. When the impingement block 3 is squeezed from above the circular upper cover hollow body 1 such that the upper edge 11 of the impact block 3 passes through the circular opening 10 of the circular upper cover hollow body 1, the circular upper cover hollow body 1 is in the 圚-shaped opening 10 The convex ring 16 is expanded and deformed downward so that the upper edge 11 of the impact block 3 can pass through the circular opening 10 of the circular upper cover hollow body 1, so that the compressed upper spring 2 built in the circular upper cover hollow body 1 will hit the impact block. 3 Quickly push down to hit the blood collection needle holder 4. Since the weight of the impact block 3 is larger than that of the blood collection needle holder 4, the collided blood collection needle holder 4 moves downward at a higher speed than the impact block 3. The lancet holder 4 on the side of the lancet has an outer rib 17 (as shown in the fourth figure) which is broken into and along the two inner grooves 18 on the inner side of the outer casing 6 (as shown in the fifth figure). Traveling until the diagonal strip 19 below the blood collection needle holder 4 comes into contact with the inner inclined surface 21 below the inner side of the outer casing 6 (as shown in the sixth figure), and at this time, the lower spring 5 is first compressed by the blood collection needle holder 4 and then The blood collection needle holder 4 is pushed up (as shown in the seventh figure). In the sixth figure, the length of the opening 22 below the outer tube 7 below the blood collection needle holder 4 is the depth at which the blood collection needle 15 penetrates into the skin. The ridge shell 6 is provided with a projection 20 opposite to the oblique opening 30 of the outer cylinder 7 coated thereon, so that the outer casing 6 and the outer cylinder 7 can rotate relative to each other and are determined according to the relative positions of the projection 20 and the oblique opening 30. The depth at which the blood collection needle 15 penetrates into the skin is as shown in the eighth figure. The leftmost blood collection needle 5 penetrates the skin to the shallowest depth, while the rightmost blood collection needle 15 penetrates the skin to the deepest depth. Another design of this patent is as shown in the ninth and tenth figures. The utility model comprises a circular upper cover hollow body 1 'with a compressed upper spring 2 and a blood collection needle holder 4 which is engaged with the upper spring 2, and the circular upper cover hollow body has a circular opening 1 〇 for the compressed The play-up match 2 shoots and pulls back the blood collection needle holder 4. The circular upper cover hollow body 1 is in turn connected to a casing 6. The outer casing 6 is provided with a - 201103500 bump 20 which is comparable to the oblique opening 30 of the outer cylinder 7 coated thereon. Therefore, when the outer casing 6 and the outer cylinder 7 are rotated at some angles, the lancet pen can have the function of adjusting the depth of penetration of the blood collection needle into the skin to facilitate adjustment of shallow finger blood collection or deep arm blood collection. The circular upper cover hollow body 1 shown in the ninth and tenth figures has a built-in upper spring 2 and a blood collection needle holder 4. A circular fixing ring 23 is fastened on the inner side of the circular upper cover hollow body 1 to fasten the upper spring 2, and the upper end of the blood collecting needle holder 4 is also provided with a circular fixing ring 23 to catch the upper spring 2. The compressed upper spring 2 has an elastic force to push the blood collection needle holder 4 toward the circular opening 10 of the circular upper cover hollow body 1, but since the diameter of the circular opening 10 is smaller than the diameter of the upper edge 11 of the blood collection needle holder 4, Therefore, the circular upper cover hollow body 1 can restrain the compressed upper spring 2 and the blood collection needle holder 4 on the circular upper cover hollow body 1 by the elasticity of rubber or plastic material. To use the blood collection needle disclosed in the present invention, the needle cover 14 attached to the blood collection needle holder 4 must be removed first, and the blood collection needle 15 is exposed, and then the force is pressed downward by the circular upper cover hollow body 1, as in the first Figure 11 shows. When the blood collection needle holder 4 is squeezed from above the circular upper cover hollow body 1 so that the upper edge 11 of the blood collection needle holder 4 passes through the circular opening 1 of the circular upper cover hollow body 1, the circular upper cover hollow body 1 is rounded The convex ring 16 of the type opening 10 is expanded downward so that the upper edge 11 of the blood collection needle holder 4 can pass through the circular opening 10 of the circular upper cover hollow body 1, so that the circular upper cover hollow body 1 has a built-in compressed upper spring. 2 will push the blood collection needle holder 4 down quickly. A round retaining ring 23 is provided above the blood collection needle holder 4 to fix the upper spring 2. The upper side of the blood collection needle holder 4 has an outer rib 17 (as shown in the tenth figure) and descends along the two inner grooves 18 on the inner side of the outer casing 6 (as shown in the fifth figure) until the blood is collected. When the diagonal strip 19 below the needle hub 4 hits the inner inclined surface 21 below the inner side of the outer casing 6, it stops (as shown in Fig. 12), and at this time, the upper spring 2 will pull back the 201103500 blood needle seat 4 (such as Figure 12). In the twelfth figure, the length of the opening 22 below the blood collection needle holder 4 which protrudes below the outer cylinder 7 is the depth at which the blood collection needle 15 penetrates into the skin. The outer casing 6 is provided with a projection 20 and a slanting opening of the outer cylinder 7 coated thereon so that the outer casing 6 and the outer cylinder 7 can rotate relative to each other and according to the projection 2 and the oblique opening 3 The relative position determines the depth of the lance 15 to penetrate the skin, as shown in Figure 14. The leftmost blood collection needle 15 penetrates the skin to the shallowest depth, while the rightmost blood collection needle 15 penetrates the skin to the deepest depth. Yet another design of the patent is as shown in the fifteenth to seventeenth. The utility model comprises a circular upper cover hollow body 1 , which has a compressed upper spring 2 and an impact block 3 , and the upper edge 11 of the impact block 3 has a slope and three or four protrusions above the inner diameter of the outer casing 6 . Some of the slopes of 31 are in contact. The circular upper cover hollow body 1 may be of plastic or rubber, and the impact block 3 may be of metal, ceramic or plastic material 'but must be heavier than the blood collection needle holder 4. The circular upper cover hollow body 1 is in turn connected to a casing 6, and the casing 6 has a blood collection needle holder 4 built therein. The heavier impact block 3 hits the lighter blood collection needle holder 4' at a low speed so that the lighter blood collection needle holder 4 can be ejected at a higher speed. The outer casing 6 is provided with a projection 20 which is inserted into the oblique opening 30 of the outer cylinder 7 coated thereon. Therefore, when the outer casing 6 and the outer cylinder 7 are rotated at some angles, the lancet pen can have the function of adjusting the depth of the skin of the blood collection needle to facilitate adjustment of the shallow finger blood collection or the deeper arm blood collection. The circular upper cover hollow body 1 shown in Fig. 15 has a built-in compressed upper spring 2 and a striking block 3. The compressed upper spring 2 has an elastic force to push the striking block 3 downward by the upper edge 11 of the striking block 3 to deform the stud 31 outward. To use the blood collection needle disclosed in the present invention, the needle cover 14 attached to the blood collection needle holder 4 must first be removed to expose the blood collection needle 15, and then pressed downward by the upper force of the 201103500 hollow body 1 in the circular upper cover. When the impact block 3 is squeezed from above the circular upper cover hollow body 1 so that the inclined surface of the upper edge 11 of the impact block 3 forces the protrusion 31 to deform outwardly so that the impact block 3 passes through the boss 31, the circular upper cover hollow body 1 is built in. The compressed upper spring 2 will push the impact block 3 down quickly to impact the blood collection needle holder 4. Since the weight of the impact block 3 is larger than that of the blood collection needle holder 4, the collided blood collection needle holder 4 moves downward at a higher speed than the impact block 3. The lancet holder 4 on the side of the lancet has a ridge 17 (as shown in the fourth figure) on both sides and descends along the two inner grooves 18 on the inner side of the outer casing 6 (as shown in the fifth figure). Traveling until the diagonal strip 19 below the blood collection needle holder 4 comes into contact with the inner inclined surface 21 below the inner side of the outer casing 6 (as shown in the sixth figure), and at this time, the lower spring 5 is first compressed by the blood collection needle holder 4 and then The blood collection needle holder 4 is pushed up (as shown in the seventh figure). In the sixth figure, the length of the opening 22 below the outer tube 7 below the blood collection needle holder 4 is the depth at which the blood collection needle 15 penetrates into the skin. The outer casing 6 is provided with a projection 20 opposite to the oblique opening 30 of the outer cylinder 7 coated thereon so that the outer casing 6 and the outer cylinder 7 can rotate relative to each other and the blood collection is determined according to the relative positions of the projection 20 and the oblique opening 30. The depth of the needle 15 into the skin, as shown in the eighth figure. The leftmost blood collection needle 15 penetrates the skin to the shallowest depth, while the rightmost blood collection needle 15 penetrates the skin to the deepest depth. The outer casing 6 and the outer cylinder 7 of the design disclosed in the fifteenth to seventeenth embodiments are different from the outer casing 6 and the outer cylinder 7 of the first drawing, wherein the oblique opening 30 of the outer cylinder 7 has a plurality of concave teeth 36 and outer The projections 20 on the casing 6 are in contact with each other to prevent mutual movement between the outer casing 6 and the outer cylinder 7 when the upper cover hollow body 1 is pressed. At the same time, the inner diameter of the outer cylinder 7 is also provided with a plurality of inner concave strips 34 in contact with the micro-bumps 35 on the outer casing 6 to prevent between the outer casing 6 and the outer cylinder 7 when the upper cover hollow body is subjected to pressure. Exercise against each other. 201103500 From the above detailed description, it is possible to make a patent application by making it possible for the person skilled in the art to understand that the creation can achieve the above objectives. However, the above description is only a preferred embodiment of the present invention, and it is not possible to limit the scope of the creation of the creation; therefore, the simple equivalent changes and modifications made by the scope of the patent application and the content of the creation specification.
