Non-contact blood sampling device and control method thereof

Abstract

The invention provides a non-contact blood sampling device. The non-contact blood sampling device comprises a support plate, a support frame, a horizontal guide rail, a connecting frame, a blood sampling frame, a puncturing arm, a puncturing power mechanism, a blood sampling needle clamping device, an assisting arm, a first auxiliary power mechanism and a second auxiliary power mechanism, whereinthe support plate is horizontally arranged; the support frame is vertically arranged on the support plate, and can axially move along the support plate; the horizontal guide rail is horizontally and perpendicularly arranged on the support frame, and can axially move along the support frame; the connecting frame can be arranged on the horizontal guide rail in a sliding manner; the blood sampling frame is rotatably arranged on the connecting frame; the puncturing arm is rotatably arranged at one end away from the horizontal guide rail, of the blood sampling frame; the puncturing power mechanismis fixedly arranged on the puncturing arm; the blood sampling needle clamping device is fixedly arranged at an output end of the puncturing power mechanism, and is used for clamping a blood sampling needle; the assisting arm is rotatably arranged at one end close to the horizontal guide rail, of the blood sampling frame; the first auxiliary power mechanism is fixedly arranged on the assisting arm;and the second auxiliary power mechanism is fixedly arranged on the first auxiliary power mechanism, and a pasting part is arranged at the output end. The invention provides a control method of the non-contact blood sampling device.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a non-contact blood sample collection device and a control method thereof. Background technique [0002] Superficial venipuncture is a very common operation in clinical practice. At present, it is basically done manually by medical staff. The success rate of one-time puncture has a lot to do with the experience of medical staff, which also leads to uneven success rate of one-time venipuncture. It not only reduces the medical efficiency, but also increases the suffering of patients, and even affects the harmonious relationship between doctors and patients in severe cases. Although the success rate of venipuncture can be improved to a certain extent with the help of vein imaging equipment, the uncertainty of manual puncture is still unavoidable. In addition, there will inevitably be contact between people during manual puncture, and there is a higher probability of outbreaks of infe...

Problems solved by technology

However, this device only controls the horizontal and vertical position, rotation angle and needle depth of the blood collection needle through a linear relationship, which inevitably produces certain errors and affects the success rate of puncture.

[0005] And the above-mentioned equipment is only theoretically realized or semi-automatic equipment. The replacement of the blood collection needle, the disinfection before the puncture, and the application of the hemostatic applicator after the puncture all need to be manually operated, and there will still be contact with everyone or indirectly. possible
