背景技术Background Art
在现代医学检验领域，血液样本的采集是诊断疾病的重要手段之一。然而，传统的血液采集方式存在诸多不便，尤其是在家庭环境中，这些不便更加明显。随着社会的发展和医疗需求的增加，家庭环境下的血液样本采集技术变得尤为重要。以下是对现有血液采集（或采样）技术的分析和对新型血液采集装置的展望。In the field of modern medical testing, the collection of blood samples is one of the important means of diagnosing diseases. However, traditional blood collection methods have many inconveniences, especially in a home environment, where these inconveniences are more obvious. With the development of society and the increase in medical needs, blood sample collection technology in a home environment has become particularly important. The following is an analysis of existing blood collection (or sampling) technology and a prospect for new blood collection devices.
现有血液采集技术的局限性，包括：医院采血的不便：医院作为传统的采血场所，常常面临排队时间长、环境复杂等问题，特别是对于老人、小孩以及行动不便的患者，到医院采血尤为困难。专业技术人员依赖：血液样本的采集通常需要专业医护人员操作，这不仅限制了采血的地点，也增加了医疗资源的负担。交叉感染风险：传统的采血技术可能存在交叉感染的风险，尤其是在多次使用同一采血设备的情况下。技术局限性：现有的多针穿刺采集技术和真空采血管技术，虽然在一定程度上解决了血液采集的问题，但仍然存在操作复杂、负压不稳定等技术难题。The limitations of existing blood collection technology include: The inconvenience of blood collection in hospitals: As a traditional blood collection site, hospitals often face problems such as long waiting times and complex environments. It is particularly difficult for the elderly, children, and patients with limited mobility to have blood drawn in hospitals. Dependence on professional technicians: The collection of blood samples usually requires professional medical staff, which not only limits the location of blood collection, but also increases the burden on medical resources. Risk of cross-infection: Traditional blood collection technology may have the risk of cross-infection, especially when the same blood collection equipment is used multiple times. Technical limitations: Although the existing multi-needle puncture collection technology and vacuum blood collection tube technology have solved the problem of blood collection to a certain extent, there are still technical difficulties such as complex operation and unstable negative pressure.

优选的，所述第一状态变为第二状态的具体过程如下：Preferably, the specific process of changing the first state to the second state is as follows:
把手下移阶段1：所述第一弹簧强度高于所述底盖的所述螺旋弹片，所述第一弹簧被压缩，在活塞继续下移过程中，所述螺旋弹片被压缩，所述第二弹簧被压缩，所述针托止口臂的斜面卡件D抵挡于所述发射筒的阻止件E，此时，所述活塞的挤推件C尚未与所述针托止口臂的斜面卡件D接触，所述单向阀盖排出气体；Handle moving down stage 1: The first spring is stronger than the spiral spring sheet of the bottom cover, the first spring is compressed, and when the piston continues to move down, the spiral spring sheet is compressed, the second spring is compressed, the inclined clamping member D of the needle holder stop arm is against the blocking member E of the launching tube, at this time, the pushing member C of the piston has not yet contacted the inclined clamping member D of the needle holder stop arm, and the one-way valve cover discharges gas;
把手下移阶段2：所述第一弹簧和所述第二弹簧继续被压缩，所述发射筒随之下移，直至所述发射筒底部中央伸出所述密封罩的A面与皮肤接触，所述发射筒抵挡于所述密封罩不再移动，所述活塞的挤推件C与所述针托止口臂的斜面卡件D接触，此时状态为第一状态；Handle down stage 2: The first spring and the second spring continue to be compressed, and the launch tube moves down accordingly, until the A surface of the sealing cover extends out of the center of the bottom of the launch tube and contacts the skin, the launch tube is blocked by the sealing cover and no longer moves, and the pushing member C of the piston contacts the inclined clamping member D of the needle holder stop arm, and the state is the first state at this time;
把手下移阶段3：所述第一弹簧、所述第二弹簧继续被压缩；所述活塞的挤推件C在所述针托止口臂的斜面卡件D的斜面上相对运动，将所述针托止口臂的斜面卡件D沿斜面向内挤压；Handle down stage 3: the first spring and the second spring continue to be compressed; the piston pushing member C moves relatively on the inclined surface of the inclined surface clamping member D of the needle holder stop arm, and squeezes the inclined surface clamping member D of the needle holder stop arm inward along the inclined surface;

使用时，将把手12逆时针旋转一定角度，听见“达”的一声，卡件061进入凹陷定位孔121位置；按图21的方向，将粘胶面014的保护膜13撕掉，将A面贴紧皮肤，按下把手12从B位置至所述顶盖顶部，所述活塞06朝相对于皮肤的方向移动，该方向为第一方向。When in use, rotate the handle 12 counterclockwise for a certain angle, and hear a "click" sound, and the clamp 061 enters the recessed positioning hole 121; according to the direction of Figure 21, tear off the protective film 13 of the adhesive surface 014, press the A surface against the skin, press the handle 12 from the B position to the top of the top cover, and the piston 06 moves in the direction relative to the skin, which is the first direction.
把手12下移阶段1：所述第一弹簧05强度高于所述底盖02的所述螺旋弹片021，所述第一弹簧05被压缩，在活塞06继续下移过程中，所述螺旋弹片021被压缩，所述第二弹簧09被压缩，所述针托04止口臂的斜面卡件D抵挡于所述发射筒11的阻止件E，此时，所述活塞06的挤推件C尚未与所述针托04止口臂的斜面卡件D接触，所述单向阀盖07排出气体；Stage 1 of downward movement of the handle 12: the first spring 05 is stronger than the spiral spring piece 021 of the bottom cover 02, the first spring 05 is compressed, and when the piston 06 continues to move downward, the spiral spring piece 021 is compressed, the second spring 09 is compressed, and the inclined clamping piece D of the stopper arm of the needle holder 04 is against the blocking piece E of the launching tube 11. At this time, the pushing piece C of the piston 06 has not yet contacted the inclined clamping piece D of the stopper arm of the needle holder 04, and the one-way valve cover 07 discharges gas;
把手12下移阶段2：所述第一弹簧05和所述第二弹簧09继续被压缩，所述发射筒11随之下移，直至所述发射筒11底部中央伸出所述密封罩01的A面与皮肤接触，所述发射筒11抵挡于所述密封罩01不再移动，此时，所述活塞06的挤推件C与所述针托04止口臂的斜面卡件D接触，此时状态为第一状态；Stage 2 of downward movement of the handle 12: the first spring 05 and the second spring 09 continue to be compressed, and the launch tube 11 moves downward accordingly, until the center of the bottom of the launch tube 11 extends out of the A surface of the sealing cover 01 and contacts the skin, and the launch tube 11 is blocked by the sealing cover 01 and no longer moves. At this time, the pushing part C of the piston 06 contacts the inclined clamping part D of the stopper arm of the needle holder 04, and the state is the first state;
把手12下移阶段3：所述第一弹簧05、所述第二弹簧09继续被压缩；所述活塞6的挤推件C在所述针托04止口臂的斜面卡件D的斜面上相对运动，将所述针托04止口臂的斜面卡件D沿斜面向内挤压；Stage 3 of the downward movement of the handle 12: the first spring 05 and the second spring 09 continue to be compressed; the pushing member C of the piston 6 moves relatively on the inclined surface of the inclined surface clamping member D of the stopper arm of the needle holder 04, and squeezes the inclined surface clamping member D of the stopper arm of the needle holder 04 inward along the inclined surface;
把手12下移阶段4：将所述针托04止口臂的斜面卡件D向内挤压出扣位，直至所述活塞06的挤推件C与所述发射筒11的阻止件E接触，所述采血针10被激发，此时状态为第二状态。所述采血针10和所述针托04在所述第一弹簧05作用下被推出所述发射筒11，所述采血针10与皮肤接触，完成穿刺并快速被所述第一弹簧05拉回。由于发射筒11的阻止件E的存在，使得针托04的斜面卡件D的上表面抵挡于发射筒11的阻止件E的下表面，使得采血针10无法复位进行第二次的穿刺；此时，所述采血针10和所述针托04一起隐藏在所述发射筒11内，实现采血针一次性激发后无法进行第二次的穿刺，避免多次穿刺导致交叉感染的问题。Stage 4 of the downward movement of the handle 12: the inclined clamp D of the stopper arm of the needle holder 04 is squeezed inward to get out of the buckle position until the pushing member C of the piston 06 contacts the blocking member E of the launch tube 11, and the blood collection needle 10 is activated. At this time, the state is the second state. The blood collection needle 10 and the needle holder 04 are pushed out of the launch tube 11 under the action of the first spring 05, and the blood collection needle 10 contacts the skin, completes the puncture, and is quickly pulled back by the first spring 05. Due to the existence of the blocking member E of the launch tube 11, the upper surface of the inclined clamp D of the needle holder 04 is against the lower surface of the blocking member E of the launch tube 11, so that the blood collection needle 10 cannot be reset for a second puncture; at this time, the blood collection needle 10 and the needle holder 04 are hidden together in the launch tube 11, so that the blood collection needle cannot be punctured for a second time after being activated once, avoiding the problem of cross infection caused by multiple punctures.
松开把手12，所述活塞06在所述第二弹簧09的作用恢复至初始B位置，因空间密封形成负压；所述发射筒11在所述底盖02的所述螺旋弹簧片21作用下回升至原位置；When the handle 12 is released, the piston 06 returns to the initial position B under the action of the second spring 09, and negative pressure is formed due to the space sealing; the launch tube 11 returns to the original position under the action of the spiral spring sheet 21 of the bottom cover 02;
同时，在负压作用下，被针刺破皮肤会持续流出少量血液，血液汇总后，在重力作用下顺着所述密封罩01的所述导向槽015汇入所述采集管011内。At the same time, under the action of negative pressure, a small amount of blood will continue to flow out from the skin pierced by the needle. After the blood is collected, it flows into the collection tube 011 along the guide groove 015 of the sealing cover 01 under the action of gravity.
采血针形成创伤，血液样本渗出后，由于量少，血液会滞留在原位，至血液达到一定体积互相吸附到一起会，且因亲水性差异，血液会顺着创伤形成流到留至所述密封罩01内。The blood collection needle forms a wound. After the blood sample seeps out, the blood will remain in place due to its small amount. When the blood reaches a certain volume, it will adsorb together. Due to the difference in hydrophilicity, the blood will flow along the wound and stay in the sealing cover 01.
所述密封罩01的A面紧密粘贴在皮肤上，加上所述唇形密封环013凸台在负压情况下紧贴皮肤，所述斜面012给血液样本流下提供缓冲，因所述斜面012为疏水新材料，表面不沾样本，汇总样本在重力作用下顺着所述导向槽015流道加速流至所述采集管011内。The A surface of the sealing cover 01 is tightly attached to the skin, and the lip-shaped sealing ring 013 boss is tightly attached to the skin under negative pressure. The inclined surface 012 provides a buffer for the blood sample to flow down. Since the inclined surface 012 is a new hydrophobic material, the surface does not stick to the sample. The collected samples are accelerated along the guide groove 015 flow channel to the collection tube 011 under the action of gravity.
隔一段时间因泄露负压会降低，可以再次压下B，所述活塞06被压缩，内部空气被排出，所述采血针10因所述发射筒11阻隔无法接触皮肤形成2次创伤，所述活塞06被放开后内部空间负压继续恢复；可以用加强负压的方式保证采血量。After a period of time, the negative pressure will decrease due to leakage, and B can be pressed again, the piston 06 is compressed, and the internal air is discharged. The blood collection needle 10 cannot contact the skin due to the obstruction of the launch tube 11, forming a second trauma. After the piston 06 is released, the negative pressure in the internal space continues to recover; the blood collection amount can be ensured by strengthening the negative pressure.
