Description

Technical Field

[0001] This application relates to the field of blood sampling device technology, specifically to an automated blood collection device. Background Technology

[0002] In medical testing and physical examinations, finger-prick blood collection is a common method for collecting blood samples. The procedure typically involves a medical professional or user manually aligning their fingertip with the collection card, puncturing the finger with a lancet, and then manually squeezing the finger to allow blood to drip onto the card. However, existing methods have limitations: in self-service collection, users often experience finger misalignment due to unfamiliarity with the procedure, resulting in inaccurate blood dripping onto the card. Furthermore, the manual contact increases the risk of cross-infection. In addition, traditional blood collection methods require manual intervention for card placement, replacement, and finger fixation, leading to low automation and efficiency, making it unsuitable for large-scale, unattended blood collection scenarios.

[0020] Reference Figure 1-5 The present application proposes an embodiment of the automatic blood collection device, which includes: The mounting base 10 has a data acquisition position 11 for placing the data acquisition card 90; Mounting base 20 is disposed above the fixed base 10 and connected to the drive mechanism 30; The positioning element 40 is detachably disposed above the fixed base 10; The squeezing member 50 is detachably mounted on the mounting base 20. A collection notch 60 corresponding to the upper and lower collection position is provided between the positioning member 40 and the squeezing member 50. The positioning member 40 is used for placing the finger to be collected and aligning the fingertip with the collection notch 60. The drive mechanism 30 is used to drive the mounting base 20 to move the pressing member 50 back and forth above the fixed base 10 to move closer to or further away from the positioning member 40 and to press the fingertip of the finger placed on the positioning member 40.

[0021] This application achieves automatic finger positioning and blood collection through the cooperation of a fixed base 10, a mounting base 20, a positioning component 40, a squeezing component 50, and a driving mechanism 30. The positioning component 40 ensures that the fingertip is accurately aligned with the collection notch 60, and the driving mechanism 30 drives the squeezing component 50 to reciprocate, which can stably control the squeezing force and frequency, simplifying the operation process, making it suitable for self-use by non-professionals, and improving the automation and reliability of blood collection. Meanwhile, the positioning component 40 and the squeezing component 50 are detachable. After the previous person finishes squeezing blood, the positioning component 40 and the squeezing component 50 used by them can be removed. When the next person needs to have blood squeezed, the new positioning component 40 and the squeezing component 50 can be placed again to squeeze blood for the next person, thus avoiding cross-infection.

[0022] The drive mechanism 30 uses a servo motor in conjunction with a lead screw slide, and the mounting base 20 is fixed on the slide. It can drive the extruder 50 to reciprocate vertically above the fixed base 10. Preferably, a finger pressing mechanism 70 is also included, which is used to press a finger onto the positioning member 40.

[0023] The finger pressing mechanism 70 can fix the finger on the positioning part 40, preventing the finger from shifting due to force during the squeezing process, ensuring that the fingertip is always aligned with the collection notch 60, further improving the accuracy of the blood collection position, and reducing the deviation of blood collection volume or blood leakage caused by finger movement.

[0024] In this embodiment, the finger pressing mechanism 70 includes a lifting drive component 71 and a pressing component 72. The pressing component 72 is mounted on the lifting drive component 71 and located above the fixed base 10. The positioning component 40 has an arc-shaped plate structure with an arc adapted to the natural bending state of the finger. The lifting drive component 71 is a miniature cylinder, which drives the pressing component 72 to lift and lower to achieve finger pressing. The structure is simple and easy to control. The output force of the lifting drive component 71 can be adjusted to avoid excessive pressing and user discomfort.

[0025] Preferably, a laser emitting device (not shown in the figure) is also included. The fixed base 10 is provided with a through hole 12 that runs vertically through it corresponding to the acquisition position 11. The laser emitting device is disposed on the fixed base 10 and located below the through hole 12. The laser emitting device is used to emit laser upwards and irradiate the finger placed at the acquisition notch 60.

[0026] The laser emitting device emits a laser upward through the through hole 12 and irradiates the finger, piercing it. This eliminates the need for medical staff to hold a blood collection needle and pierce the finger, thus improving the level of automation.

[0027] Furthermore, it also includes a paper feeding mechanism 80, wherein the positioning member 40, the squeezing member 50 and the mounting base 20 have a gap with the fixed base 10, and the paper feeding mechanism 80 is used to transport the acquisition card 90 from one side of the fixed base 10 to the acquisition position 11, and is also used to send the acquisition card 90 out from the other side of the fixed base 10.

[0028] The paper feeding mechanism 80 automatically delivers the collection card 90. In this embodiment, after the finger is placed at the collection notch 60, the paper feeding mechanism 80 delivers the collection card 90 to the collection position 11. The driving mechanism 30 is activated and drives the squeezing member 50 to move back and forth to squeeze blood. After the blood collection is completed, the paper feeding mechanism 80 continues to deliver the collection card 90, so that the collection card 90 is delivered from the other side of the fixed seat 10. There is no need to manually place the collection card 90, avoiding hand contact with the collection card 90 and causing contamination. At the same time, it realizes continuous blood collection operation, improves the efficiency of batch blood collection, and is especially suitable for scenarios such as physical examination centers.

[0029] Referring to the attached drawings, the paper feeding mechanism 80 includes a pair of paper feeding wheels 82 arranged opposite to each other. The paper feeding wheels 82 rotate in opposite directions and transport the collection card 90 to the collection position 11 by friction. After the blood is squeezed out, the paper feeding wheels 82 start to rotate again so that the collection card 90 is sent out from the other side of the fixed seat 10 and can be removed. The paper feeding mechanism 80 can then transport the next collection card 90.

[0030] Preferably, the paper feeding mechanism 80 further includes a paper feeding device 83, which is used to transport stacked collection cards 90 one by one to the paper feeding roller pair 82. The structure and working principle of the paper feeding device 83 are prior art, and this application will not describe its structure and working principle in detail.

[0031] In this embodiment, the positioning member 40 is slidably connected to the squeezing member 50. The squeezing member 50 is mounted on the mounting base 20 and moves back and forth relative to the positioning member 40 with the mounting base 20. When installing the squeezing member 50 and the positioning member 40, simply installing the squeezing member 50 on the mounting base 20 completes the installation. Similarly, after blood collection, removing the squeezing member 50 allows both the squeezing member 50 and the positioning member 40 to be removed simultaneously, making it more convenient to use.

[0032] Furthermore, the upper end of the fixed base 10 is provided with protrusions 13 on both sides opposite to the collection position 11. The positioning member 40 is placed on the upper end of the protrusion 13 so that the positioning member 40 can be stably placed on the protrusion 13 under the action of the finger placed on it. When the squeezing member 50 moves back and forth relative to the positioning member 40, the positioning member 40 can also be stably placed.

[0033] In this embodiment, the extrusion member 50 is U-shaped with the opening facing upward. The upper ends of both sides of the extrusion member 50 are detachably connected to the mounting base 20. An avoidance hole 51 is provided on one side of the lower end of the extrusion member 50. The positioning member 40 is disposed at the avoidance hole 51 and is slidably connected to the extrusion member 50.

[0034] Referring to the accompanying drawings, the extrusion member 50 has grooves on both sides of the clearance hole 51, and the positioning member 40 has sliding strips on both sides that match the grooves. In this embodiment, the positioning member 40 is U-shaped, with one end slidably connected to the extrusion member 50 and the other end placed on the upper end of the boss 13. The other end of the positioning member 40 has small holes corresponding to the upper and lower parts of the collection notch, allowing blood to fall onto the collection position through the collection notch and the small holes.

[0035] Furthermore, the mounting base 20 includes two positioning strips 21, each with a positioning post 22. The upper ends of both sides of the extrusion member 50 are respectively provided with outward flanges, each with a positioning hole 52. The outward flanges are placed on the positioning strips 21, and the positioning posts 22 extend into the positioning holes 52, thereby enabling the installation of the extrusion member 50 and facilitating its assembly and disassembly.

[0036] It also includes a gravity detection mechanism (not shown in the figure), which is used to weigh the fixed platform. In this embodiment, the gravity detection mechanism can monitor the weight change of the collection card 90 on the fixed platform in real time to determine whether the amount of blood dripping onto the collection card 90 is sufficient, so that the device can automatically trigger subsequent operations, such as sending the collection card 90 out of the collection position 11. The gravity detection mechanism uses a piezoelectric weighing sensor, which is installed at the bottom of the fixed base 10. During the blood collection process, the weight change at the bottom of the fixed base 10 is used to determine whether blood has dripped onto the collection card 90.

[0037] It also includes an ultraviolet (UV) disinfection mechanism (not shown in the figure), which is installed on the mounting base 10 and used to disinfect the mounting base 10 by UV irradiation. The UV disinfection mechanism can disinfect the mounting platform and surrounding components, reducing residual bacteria, viruses, and other contaminants during multiple blood collections, lowering the risk of cross-infection, and is especially suitable for scenarios where multiple people share the equipment, improving the hygiene and safety of the blood collection process. In this embodiment, the UV disinfection mechanism is distributed on the upper edge of the mounting base 10, and can irradiate the mounting base 10 and its surroundings. After each blood collection, the UV lamp is turned on for disinfection.

[0038] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
