Multi-link mechanism for blood sampling robot device

Abstract

The invention provides a multi-link mechanism for a blood sampling robot device. The multi-link mechanism comprises a driving connecting rod, a fixed connecting rod, a first connecting rod, a second connecting rod, a third connecting rod and a fixed plate. The driving connecting rod is connected with the driving device and can rotate around the first center under the driving of the driving device.The fixed connecting rod is hinged to the driving connecting rod at the first center and fixed to a ultrasonic probe fixing clamp. The first connecting rod is parallel to the fixed connecting rod andhinged to the driving connecting rod. The second connecting rod is parallel to the driving connecting rod and hinged to the fixed connecting rod and the first connecting rod. The third connecting rodis parallel to the fixed connecting rod and hinged to the driving connecting rod and the second connecting rod at the same time. The fixed plate is hinged to the first connecting rod at the third center and hinged to the third connecting rod at the fourth center. The connecting line of the third center and the fourth center is parallel to the driving connecting rod. By means of the multi-link mechanism, the blood taking needle can stably and accurately move.

Description

technical field [0001] The present disclosure relates to the technical field of medical devices, in particular to a multi-link mechanism for a blood collection robot. Background technique [0002] At present, when nurses use the existing artificial venous blood collection methods, there are problems such as heavy workload, complicated procedures, and difficult to find blood vessels, which not only brings a lot of inconvenience to their work, but also increases the suffering of patients. In the process of blood collection, contact and exposure between medical staff and patients cannot be avoided, and there is a risk of bacterial infection, which brings about hidden dangers in the occupational safety of medical staff. At present, the automatic venous blood collection robot technology has shortcomings such as insufficient blood collection success rate. One of the reasons for the insufficient blood collection success rate is that the design structure related to the movement of t...

[0002] At present, when nurses use the existing artificial venous blood collection methods, there are problems such as heavy workload, complicated procedures, and difficult to find blood vessels, which not only brings a lot of inconvenience to their work, but also increases the suffering of patients

In the process of blood collection, contact and exposure between medical staff and patients cannot be avoided, and there is a risk of bacterial infection, which brings about hidden dangers in the occupational safety of medical staff.

At this stage, the automatic venous blood collection robot technology has shortcomings such as insufficient blood collection success rate. One of the reasons for the insufficient blood collection success rate is that the design structure related to the movement of the blood collection needle cannot make the blood collection needle move stably and accurately.
