技术领域technical field

本发明属于血液采集设备技术领域,具体涉及一种一次性简易自助无痛式采血装置。The invention belongs to the technical field of blood collection equipment, and in particular relates to a disposable simple self-service painless blood collection device.

背景技术Background technique

随着科学技术的飞速发展,医疗领域也紧跟着时代的步伐,人们在就医时,采血检查是常见的一种检查手段,通常采用的采血方法有静脉采血和指尖采血。静脉采血通常采血量较大,可以从1毫升到上百毫升不等。静脉采血的用途很多,可以用于生化检测、游离核酸检测等等。同时,静脉采血的装置也有很多种,可以分为血浆、血清等采血管。因此,静脉采血是当前血液检测中应用最广泛的采血方式。但是静脉采血通常需要由专业的医护人员手动处理操作,无法通过自助的形式进行采集,使医护人员的采血工作量较大。With the rapid development of science and technology, the medical field is also closely following the pace of the times. When people seek medical treatment, blood collection is a common inspection method. The commonly used blood collection methods include venous blood collection and fingertip blood collection. Venous blood collection usually takes a large amount of blood, which can vary from 1 milliliter to hundreds of milliliters. There are many uses of venous blood collection, which can be used for biochemical detection, cell-free nucleic acid detection, etc. At the same time, there are many kinds of venous blood collection devices, which can be divided into blood collection tubes such as plasma and serum. Therefore, venous blood collection is the most widely used blood collection method in current blood testing. However, venous blood collection usually needs to be handled manually by professional medical staff, and cannot be collected in the form of self-help, which makes the blood collection workload of medical staff large.

Before blood collection, when the annular silicone ring is pressed against the skin, it can compress the nerve endings to reduce pain, and at the same time, it can collect the blood at the attachment site, which is convenient for blood collection and improves the blood collection effect;

2、抽取血液时,使用人只需将按压块往下按压,即可通过负压,将人体的血液由第一金属针头抽出,经过空腔内部的导液接头流至各个塑料导液管,最后采集的血液流经第二金属针头采集至储血腔中;2. When drawing blood, the user only needs to press down the pressing block, and the blood of the human body can be drawn out from the first metal needle through the negative pressure, and flow to each plastic catheter through the catheterization joint inside the cavity. The blood finally collected flows through the second metal needle and is collected into the blood storage cavity;

3、采集完成后,松开按压块,弹簧弹性回弹复位,带动环形限位挡块上升,从而使按压块上升,从而将第一金属针头重新缩回下腔体中,避免人体误触造成伤害,同时第二金属针头上升复位脱离弹性橡胶片缩回上腔体中;3. After the collection is completed, release the pressing block, the spring elastically rebounds and resets, and drives the annular limit block to rise, so that the pressing block rises, thereby retracting the first metal needle into the lower cavity again to avoid the accidental contact of the human body. Injury, at the same time the second metal needle rises, resets, detaches from the elastic rubber sheet and retracts into the upper cavity;

4、锥形微孔由于弹性橡胶片本身的弹性,能够将锥形微孔下端弹性封堵,避免下腔体与环形围挡之间的真空环境中进入空气;当第二金属针头插入弹性橡胶片时,第二金属针头引起插入弹性橡胶片弹性扩张,使锥形微孔变大,从而使第二金属针头能够方便的插入下腔体中,通过下腔体与环形围挡之间抽真空处理形成负压抽取血液,抽取完成后,拔出第二金属针头,弹性橡胶片回弹,锥形微孔回到初始状态,从而使血液不会从弹性橡胶片漏出,使血液能够得到很好地保存,便于携带。4. Due to the elasticity of the elastic rubber sheet itself, the conical micro-hole can elastically seal the lower end of the conical micro-hole to prevent air from entering the vacuum environment between the lower cavity and the annular enclosure; when the second metal needle is inserted into the elastic rubber When the second metal needle is inserted into the elastic rubber sheet, the elastic expansion of the elastic rubber sheet causes the conical micro-hole to become larger, so that the second metal needle can be easily inserted into the lower cavity, and the vacuum is drawn between the lower cavity and the annular enclosure. The treatment forms a negative pressure to extract blood. After the extraction is completed, the second metal needle is pulled out, the elastic rubber sheet rebounds, and the conical micro-hole returns to the initial state, so that the blood will not leak from the elastic rubber sheet, so that the blood can be obtained well. It can be stored on the ground and easy to carry.

抽取血液时,使用人将按压块22往下按压,按压块22往下运动,使环形限位挡块222往下运动,克服弹簧33弹力将弹簧33压缩,一方面使下腔体3的第一金属针头23穿过第一橡胶封口34,从而使第一金属针头23能够穿刺人体血管采集血液,另一方面使上腔体2中的第二金属针头242能够穿过弹性橡胶片21,进入下腔体3与环形围挡31之间形成的储血腔32中,由于储血腔32中为真空状态,因此能够形成负压,将人体的血液由第一金属针头23抽出,经过空腔221内部的导液接头24流至各个塑料导液管241,最后采集的血液流经第二金属针头242采集至储血腔32中,并且储血腔32中还可放置抗凝血剂,避免采集的血液凝固;When the blood is drawn, the user presses the pressing block 22 downward, and the pressing block 22 moves downward, so that the annular limit stop 222 moves downward, and the spring 33 is compressed against the elastic force of the spring 33. A metal needle 23 passes through the first rubber seal 34, so that the first metal needle 23 can puncture a human blood vessel to collect blood, and on the other hand, the second metal needle 242 in the upper cavity 2 can pass through the elastic rubber sheet 21 and enter In the blood storage cavity 32 formed between the lower cavity 3 and the annular enclosure 31, since the blood storage cavity 32 is in a vacuum state, a negative pressure can be formed, and the blood of the human body can be drawn out from the first metal needle 23 and passed through the cavity. The catheter connector 24 inside the 221 flows to each plastic catheter 241, and the blood finally collected flows through the second metal needle 242 and is collected into the blood storage chamber 32, and an anticoagulant can also be placed in the blood storage chamber 32 to avoid The blood collected is clotted;

采集完成后,松开按压块22,弹簧33弹性回弹复位,带动环形限位挡块222上升,从而使按压块22上升,从而将第一金属针头23重新缩回下腔体3中,避免人体误触造成伤害,同时第二金属针头242上升复位脱离弹性橡胶片21缩回上腔体2中;After the collection is completed, release the pressing block 22, the spring 33 elastically rebounds and resets, and drives the annular limit stop 222 to rise, so that the pressing block 22 rises, thereby retracting the first metal needle 23 back into the lower cavity 3 to avoid The human body accidentally touches and causes injury, and at the same time, the second metal needle 242 rises, resets, separates from the elastic rubber sheet 21 and retracts into the upper cavity 2;

本发明只需人将装置按压于采血部位,将按压块往下按压即可对人体采血,结构简单,操作使用方便,可以通过自助的形式进行采集,减轻医护人员工作量。The invention only needs to press the device on the blood collection site and press the pressing block downwards to collect blood from the human body.

具体的,弹性橡胶片21上表面设有与第二金属针头242位置相匹配的锥形微孔211,锥形微孔211底面朝上,顶点朝下设置。这样的结构,当第二金属针头242未插入弹性橡胶片21时,锥形微孔211由于弹性橡胶片21本身的弹性,能够将锥形微孔211下端弹性封堵,避免下腔体3与环形围挡31之间的真空环境中进入空气;当第二金属针头242插入弹性橡胶片21时,第二金属针头242引起插入弹性橡胶片21弹性扩张,使锥形微孔211变大,从而使第二金属针头242能够方便的插入下腔体3中,通过下腔体3与环形围挡31之间抽真空处理形成负压抽取血液,抽取完成后,拔出第二金属针头242,弹性橡胶片21回弹,锥形微孔211回到初始状态,从而使血液不会从弹性橡胶片21漏出,使血液能够得到很好地保存,便于携带。实际上,也可根据情况考虑使用其他结构,使抽血后血液不会从弹性橡胶片21漏出,使血液能够得到很好地保存,便于携带。Specifically, the upper surface of the elastic rubber sheet 21 is provided with a tapered micro-hole 211 that matches the position of the second metal needle 242 , and the tapered micro-hole 211 is arranged with the bottom facing upward and the apex facing downward. With such a structure, when the second metal needle 242 is not inserted into the elastic rubber sheet 21, the conical micro-hole 211 can elastically seal the lower end of the conical micro-hole 211 due to the elasticity of the elastic rubber sheet 21, so as to prevent the lower cavity 3 from being connected with the elastic rubber sheet 21. Air enters into the vacuum environment between the annular enclosures 31; when the second metal needle 242 is inserted into the elastic rubber sheet 21, the second metal needle 242 causes the elastic rubber sheet 21 to be inserted elastically to expand, so that the conical micro-hole 211 becomes larger, thereby The second metal needle 242 can be easily inserted into the lower cavity 3, and the negative pressure is formed by vacuuming between the lower cavity 3 and the annular enclosure 31 to draw blood. After the extraction is completed, the second metal needle 242 is pulled out, elastic The rubber sheet 21 rebounds, and the conical micro-holes 211 return to the initial state, so that the blood will not leak from the elastic rubber sheet 21, so that the blood can be well preserved and easy to carry. In fact, other structures can also be considered according to the situation, so that the blood will not leak from the elastic rubber sheet 21 after the blood is drawn, so that the blood can be well preserved and easy to carry.

具体的,锥形微孔211底面形状为圆形及正多边形中任意一种。这样的结构,使锥形微孔211的结构简单,便于加工和生产。实际上,也可根据情况考虑使用其他结构,使锥形微孔211的结构简单,便于加工和生产。Specifically, the shape of the bottom surface of the tapered micro-hole 211 is any one of a circle and a regular polygon. Such a structure makes the structure of the tapered micro-hole 211 simple, and facilitates processing and production. In fact, other structures can also be considered according to the situation, so that the structure of the tapered micro-holes 211 is simple and convenient for processing and production.
