Problems solved by technology

[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 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

Embodiment 1

[0034] Such as Figure 1~4 As shown, the present invention is an intelligent blood collection machine capable of automatic needle exchange, comprising an operating arm 1 of a blood drawing robot, a needle lowering adjustment bracket 2 is arranged at the end of the operating arm 1, and a syringe 30, a needle exchange mechanism, a pusher Needle mechanism, blood drawing and needle removal mechanism, needle sealing mechanism, among which:

[0035] The needle changing mechanism includes a large cylinder 3 and a small cylinder, the circumferential side walls of the large cylinder 3 and the small cylinder are integrally formed and connected, and the central axes are parallel to each other, and the large cylinder 3 is connected with the lower needle adjustment bracket 2 through the mounting bracket. The bottom end is connected, and a circle of superior arc baffles 4 and inferior arc baffles 5 are arranged in the large cylinder 3, and the superior arc baffles 4 and inferior arc baffles...

Embodiment 2

[0044] Such as Figure 5 As shown, on the basis of Embodiment 1, the return spring 12 includes a limiting cylinder 121, a coil spring 122, an A arc-shaped plate 123, and a B arc-shaped plate 124. One end of the limiting cylinder 121 is connected to the A arc-shaped The plate 123 is connected, and the other end is the open end of the oval inner cavity. The coil spring 122 is matched with the oval inner cavity of the limiting cylinder 121. One end of the coil spring 122 is placed in the limiting cylinder and A arc-shaped plate 123 connection, and the other end is connected to the B arc-shaped plate 124. The inventor designed the limiting cylinder as an ellipse, which can greatly increase the cross-sectional area of ​​the coil spring along the axial direction of the large cylinder, further limit the force direction of the coil spring, improve the stability of the coil spring, and make the service life of the needle changing mechanism Huge improvements.

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 ...
