Embodiment Construction
[0045] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0046] The blood collection device provided by the embodiment of the present invention is composed of a plurality of microneedles with small diameters arranged in order to form a microneedle array. The wound on the skin is very small, so the person receiving the blood collection will not feel any pain. During the blood collection process, the downward movement of the first microneedle assembly can be precisely controlled. Cortex, and inject the anesthetic into the skin tissue of the blood-collected person, and then control the second microneedle assembly to move downward, so that the microneedle pe...

The present invention is applicable to the field of medical equipment, and provides a blood collection device and its control equipment. The blood collection device includes: a first microneedle assembly with an anesthetic release channel; a second microneedle assembly with a blood collection channel; driving the first microneedle assembly A microneedle assembly injects the first moving structure of anesthetic into the epidermis; drives the second microneedle assembly to collect blood from the skin; and communicates with the second microneedle assembly for storing the collected Blood storage structure for blood. The blood collection device provided by the present invention has a plurality of microneedles with small diameters arranged in an orderly manner to form a microneedle array, and the wound formed by the needle piercing the skin is small; and the penetration depth of the microneedles can be precisely controlled during the blood collection process, The anesthetic is released when it is inserted into the epidermis of the skin. After the anesthesia is completed, it is inserted into the dermis to draw blood. During the whole process, the patient will not feel pain, and blood can be collected without pain.
Description
technical field [0001] The invention belongs to the field of medical equipment, in particular to a blood sampling device and its control equipment. Background technique [0002] Collecting blood to provide laboratory samples is one of the routine testing methods in clinical testing. In the prior art, the commonly used blood collection method is to puncture a vein and collect blood, or to prick the tip of a finger, and then squeeze out the blood and collect it. This method is mostly used for the regular detection of blood sugar levels in diabetic patients. [0003] However, during the research and practice of the prior art, the applicant of the present application found that the prior art has the following defects: venipuncture blood collection is usually painful, and generally requires professional medical personnel to perform it to reduce damage; However, the method of needling the tip of the finger has less blood collection and is more painful, and for children, because c...
