Embodiment Construction
[0015] In order to make the technical problems, technical solutions and beneficial effects to be solved by 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.
[0016] see Figure 1 to Figure 5 In a preferred embodiment of the present invention, the laser blood collection instrument includes a housing 10, a power supply circuit 11 and a laser control circuit 12 arranged in the housing 10, a buzzer 13, an operation button 14 arranged on the surface of the housing 10, and Display 15.
[0017] The laser control circuit 12 includes a control unit 121, an impedance detection circuit 122 connected to the control unit 121, a laser trigger circuit 123 connected to the control unit 121, a detection electrode 124 connected to the i...

A laser blood collection instrument, comprising a housing, a power supply circuit arranged in the housing, and a laser control circuit, the laser control circuit comprising a control unit, an impedance detection circuit connected to the control unit, and a circuit connected to the control unit A laser trigger circuit, a detection electrode connected to the impedance detection circuit, and a laser head connected to the laser trigger circuit, the laser head and the detection electrode are arranged on the outer surface of the housing; the impedance detection circuit passes the detection The electrode detects the characteristic value of the human body impedance of the person to be blood sampled, and the control unit controls the laser trigger circuit to trigger the laser head to emit a laser with a corresponding intensity level according to the characteristic value of the human body impedance. In this way, according to the skin characteristics of different people, accurate Automatically set the laser intensity level, avoiding the excessive damage caused by too high laser intensity during blood collection, and the problem of blood collection failure caused by too low laser intensity.
Description
technical field [0001] The invention relates to medical instruments, in particular to a laser blood sampling instrument. Background technique [0002] As a medical clinical test, the most common way to collect blood as a test sample is to quickly pierce the fingertip with a disposable blood collection needle. Although this method is very simple, it has many shortcomings: First, it tears the skin tissue irregularly. Dehiscence, the second is closely related to the operator's proficiency in the operation, and the blood-collected patients often feel very intense pain, especially infants, who often cry, which affects the operation, and usually causes a large amount of interstitial fluid, extracellular fluid and other impurities to leak out of the epidermis , mixed with blood samples to affect the test results, accompanied by local edema on the skin surface. Therefore, blood collection in wards in some hospitals has been replaced by complicated and costly venous blood. However,...
