Research On A Clinically Oriented Fully Automatic Blood Collecting Test Tube Capping System

Currently,the capping of blood collection tubes in clinical laboratories is mostly done manually by medical personnel.Manual capping results in heavy labor and low work efficiency for medical personnel.There are also the following problems:due to improper force by medical personnel,the tube mouth is broken,causing scratches,contaminating blood samples,exposing medical personnel to highly pathogenic environments,and endangering the health of medical personnel.However,the current large-scale commercial assembly lines are expensive,costly in consumables,and difficult to fully popularize due to their numerous functions.Therefore,clinical laboratories currently rely mainly on manual capping of test tube caps.Therefore,it is of great significance to carry out research on the clinically oriented automated blood collection tube capping system.To meet the needs of clinical laboratories for capping blood collection tubes,this article has conducted research and development on the capping system from structural design,finite element analysis,control system,and other aspects,and implemented clinical applications in clinical laboratories.The research content of this article is as follows:Firstly,the functional requirements of the system were clarified.Aiming at the functional requirements of the fully automatic blood collection tube cap system,the overall scheme design and process planning of the system were completed,and three-dimensional modeling was completed using SolidWorks software.Using ANSYS Workbench finite element software,the modal analysis of the working table of the capping mechanism was carried out;At the same time,the software is used for static analysis of the support structure cap system was analyzed using ADAMS software.During the simulation,different speed drive signals were used to drive the cylinder and motor,and the vibration simulation of each shaft was observed.According to the design requirements and structural scheme,the control logic of the cap system is designed.Use Stateflow software to simulate the timing logic of the control logic to confirm the correctness of the logic.Allocate ports to the PLC based on the controlled quantities of the two modules.Finally,the physical construction is completed and the system is tested.It mainly involves functional experiments on the feeding module and the gland module to verify the realizability.Observe the problems encountered in clinical application experiments of the system,analyze the problems,and propose solutions.
