Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a capillary blood collection device that can be operated by prying. Background Technology

[0002] A disposable capillary blood collection device is a medical device used to collect capillary blood. It typically consists of a needle, a tubing, a housing, and operating components. Its working principle is to collect a small amount of blood by piercing a capillary blood vessel such as a finger or earlobe, and then deliver it to the tubing for collection and analysis.

[0003] After a finger is cut, a capillary blood collection tube and a negative pressure collection bottle are generally used to draw blood from the finger. Because capillary blood collection tubes are small, the position of the finger and the capillary blood collection tube needs to be constantly adjusted during collection to ensure effective aspiration. Negative pressure collection bottles are easy to operate, but if the negative pressure is insufficient due to operation or other reasons, resulting in no blood being drawn in or a small amount being drawn in, and the negative pressure aspiration is not completed in one go, the negative pressure collection bottle will lose its negative pressure effect and cannot be used again, requiring replacement with a new negative pressure collection bottle.

[0004] To address the issues of inconvenient operation of capillary blood collection tubes and the need to replace negative pressure collection bottles if negative pressure aspiration is not completed in one go, a convenient and reusable peripheral blood collection device is designed to overcome these problems. Utility Model Content

A connecting rod 4 is fixedly connected to the lower end of the slider 3, and a spring 5 is sleeved on the connecting rod 4. A pin 6 is fixedly connected to the lower end of the connecting rod 4. A support plate 7 is fixedly connected inside the transparent shell 1. The surface of the support plate 7 has an opening. The spring 5 is used to spring back the button 2. The opening on the surface of the support plate 7 allows the pin 6 to pass through. An arc-shaped opening is provided on one side of the lower end of the transparent shell 1. The arc-shaped opening at the lower end of the transparent shell 1 allows a finger to be inserted. An arc-shaped groove is provided at the lower end of the transparent shell 1. An opening is provided at the upper end of the arc-shaped groove at the lower end of the transparent shell 1. The pin 6 is located above the opening of the arc-shaped groove at the lower end of the transparent shell 1. The arc-shaped opening at the lower end of the transparent shell 1 can position the finger, thereby facilitating blood collection.

[0030] Please see Figure 6 - Figure 9 In this embodiment, the collection assembly includes a guide vessel 9. A guide vessel 9 is fixedly connected to one side of the transparent shell 1, penetrating the transparent shell 1. One end of the guide vessel 9 is located inside a side insertion port 8. A storage vessel 10 is slidably connected inside the side insertion port 8. A rubber stopper 11 is fixedly connected to one end of the storage vessel 10. One end of the guide vessel 9 passes through the rubber stopper 11 and is located inside the storage vessel 10. An upper catheter 13 is fixedly connected to the upper end of the storage vessel 10. The lower end of the upper catheter 13 passes through the storage vessel 10. A piston 18 is slidably connected inside the upper catheter 13. A threaded rod 16 is fixedly connected to the upper end of the piston 18. A lever 17 is fixedly connected to the upper end of the threaded rod 16 for rotating the threaded rod 16. A threaded cap 12 is fixedly connected to the upper end of the upper catheter 13, and the threaded cap 12 is threadedly connected to the threaded rod 16. Side catheter 14 and side catheter 2 15 are fixedly connected to one side of the upper catheter 13. Side catheter 14 is located outside the storage vessel 10, and side catheter 2 15 is located inside the storage vessel 10. Piston 2 19 is slidably connected inside side catheter 14. Spring 2 20 is provided inside side catheter 14 to determine the position of piston 2 19. Piston 3 21 is slidably connected inside side catheter 2 15. Spring 3 22 is provided inside side catheter 2 15 to determine the position of spring 3 22. Both piston 2 19 and side catheter 14 have openings on their surfaces. Initially, the opening of piston 2 19 is located on the side of side catheter 14 closer to the opening of upper catheter 13. Both piston 3 21 and side catheter 2 15 have openings on their surfaces. Initially, the opening of piston 3 21 is located on the side of side catheter 2 15 away from the opening of upper catheter 13.

[0031] During use, first align the lower opening of the transparent casing 1 with the outstretched finger placed on the table. Then, quickly press button 2. Simultaneously, the slider 3 at the lower end of button 2 moves downward, and the pin 6 at the lower end of the connecting rod 4 cuts the finger. After the pin 6 cuts, the spring 5 at the support plate 7 springs the pin 6 back, and blood flows out. Then, use your thumb to turn the dial 17. As the dial 17 rotates, the threaded rod 16 on the threaded cover 12 moves upward, and the piston 18 at the lower end of the threaded rod 16 moves upward in the upper conduit 13. The gas pressure in the upper conduit 13 decreases, and under the action of pressure, piston 21 moves to one side. When the opening of piston 21 coincides with the opening of the side conduit 15, a small amount of gas in the storage tube 10 is drawn into the upper conduit 13, and the pressure in the storage tube 10 decreases, creating a negative pressure. Due to the negative pressure, blood from the finger is drawn into the storage tube 10 through the guide tube 9, thus completing the blood collection. After completing the above steps, remove the storage tube 1. Remove the rubber stopper 11 from the side port 8. The rubber stopper 11 not only secures the connection between the blood storage tube 10 and the side port 8, but also automatically closes the opening of the rubber stopper 11 after the blood storage tube 10 is removed, thus ensuring blood storage. Due to operational reasons, insufficient airtightness often leads to insufficient negative pressure, resulting in blood not being able to be drawn in or only a small amount being drawn in. Existing negative pressure collection devices cannot recreate a negative pressure environment after the negative pressure is drawn in, and collection cannot be performed again when the above situation occurs. When this blood collection device encounters this situation, the dial 17 is rotated in the opposite direction, the threaded rod 16 is lowered, and the piston 18 simultaneously squeezes the air downwards. At this time, the piston 3 21 is pulled back to its original position by the spring 3 22. The gas in the upper conduit 13 can only squeeze the piston 2 19. When the opening of the piston 2 19 coincides with the opening of the side conduit 14, the air in the upper conduit 13 is forced out. When the dial 17 is rotated again to make the piston 18 move upwards, a negative pressure environment can be generated again, and blood can be drawn in again.

[0032] Through the above steps, this capillary blood collection device can collect blood immediately after pricking the fingertip. Compared with existing capillary collection tubes, the negative pressure suction operation generated by flicking is more convenient and stable. Compared with existing negative pressure collection bottles, when the negative pressure is insufficient due to insufficient airtightness caused by operation or other reasons, resulting in insufficient blood suction or insufficient suction volume, negative pressure suction can be performed again without replacement.

[0033] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
