Intelligent blood sampling device capable of achieving automatic needle exchange

Abstract

The invention discloses an intelligent blood sampling device capable of achieving automatic needle exchange. A propeller is removed from a needle insertion adjustment support at the tail end of an operation arm of an existing blood drawing robot, a needle exchange mechanism, a needle push mechanism, a blood drawing needle separation mechanism and a needle seal mechanism are added, the improved robot is provided with a specific syringe, through the structure, the improved blood drawing robot can automatically complete the processes of needle exchange, blood drawing, needle seal and needle separation, the manual labor amount is greatly reduced, the automation process of blood drawing of the robot is achieved, needle taking is conducted conveniently, the problem is effectively avoided that people are more easily scratched by a syringe needle during needle taking or assembly, and the device has high economic and practical value; meanwhile, by adopting the needle seal structure, a needle cover covers the syringe needle, bacteria in air can be prevented from entering blood of the syringe from a syringe needle hole, the precision of following blood detection can also be improved accordingly, and the device is safe and hygienic.

Description

technical field [0001] The invention relates to a medical robot, in particular to an intelligent blood collection machine capable of automatic needle replacement. Background technique [0002] In the process of manual blood drawing, if no vein is found or the needle is pierced too deeply, it will often bring pain to the patient. However, most hospitals now use manual blood drawing, and the experience of blood drawing is mostly the same as that of medical staff. Technology is closely related; and the manual blood drawing method is cumbersome and inefficient. [0003] Therefore, with the development of science and technology, medical devices are becoming more and more intelligent, and there are products on the market that use robots instead of manual blood draws. This blood collection robot uses infrared and ultrasonic imaging technology to replace nurses to give patients injections and blood draws. Although currently The probability of accurate blood drawing is 83%, but the ...

[0002] In the process of manual blood drawing, if no vein is found or the needle is pierced too deeply, it will often bring pain to the patient. However, most hospitals now use manual blood drawing, and the experience of blood drawing is mostly the same as that of medical staff.

[0003] Therefore, with the development of science and technology, medical devices are becoming more and more intelligent, and there are products on the market that use robots instead of manual blood draws. This blood collection robot uses infrared and ultrasonic imaging technology to replace nurses to give patients injections and blood draws. Although currently The probability of accurate blood drawing is 83%, but the whole blood drawing process still needs to be manually controlled, and the problem of being easily infected by the needle secondary injury in the existing manual blood drawing method cannot be avoided in each needle replacement process, and the replacement The needle blood drawing process cannot be fully automated, the overall efficiency is still low, and the problem of manual blood drawing has not been fundamentally solved
