The injector type to injects the pump application quality influence the experimental study

Appraises the different disable syringe injector to inject the pump application quality the influence. Method: The shell bright 8714843 injection pump separately with 10ml Bei Lang, clean auspicious, the new Tianjin sign injector and 50ml Bei Lang, clean Switzerland, the jade rises the sign injector coordination use, examines its actual speed of flow, the contrast result. Finally: When uses the 10ml non-shell bright injector, the current syringr for single use error exceeds the allowed figure seriously, respectively is 7.30% and - 14.14%. When uses the 50ml non-shell bright injector, the accuracy change is small, the average error respectively is 0.23% and - 1.15%. Conclusion: The injector type to injects the pump application quality the influence to be noticeable, should choose prudently in the clinical use.

a false setting on the syringe was suspected to be the cause of the problem.

In the second patient, however, a false setting on the syringe was suspected to be the cause of the problem. In order to prove this, we tried to reproduce the situation where a syringe pump, due to a false syringe setting, abruptly Special Syringe while giving a "syringe loss" warning, after a period of precise functioning. Once we had determined how a false setting of the syringe could occur without the syringe pump giving off an alarm from the onset, we collaborated with the Terumo Company to revise their current medical syringe manual to incorporate this as a warning. We also helped in the development of a new model, including a new safety feature that would prevent a false setting of the syringe from occurring at all.

New multi-purpose automatic control infusion installment infusion speed stability examination

Examines one kind of insulin syringe innovation invention the new multi-purpose automatic control solution infusion speed stability. Method: In view of different model injection needle, wrap base pin as well as different type liquid test new infusion installment infusion speed stability. Finally: The infusion speed with injects needle's size to become is being related, but by no means linear relation. infusion set the infusion speed will increase thickly along with the set of base pin inside diameter increases. The different type liquid's infusion speed is inconsistent, the concentration red blood cell is slowest, but the physiological saline is quickest. Does not pressurize when in each kind of situation each kind of liquid highest insulin pen needle speed basic constant. Conclusion: The new infusion installment infusion accuracy is high, the speed of flow control is accurate, ease of operation, portable.
