Carried on the exploration testing of flow rate of infusion device about industry standard YY 0451-2010. Engaged in flow rate experiments adopting different method that are provided by new and old industry standard for samples of the same type. Compared with the result of the dangerous coefficient by calculating the test data, the old standard can be more sensitive to reflect the situation of product flow rate, so it can be applied to conventional control of the products. The method which provided by the new industry standard is suitable for evaluating periodicity the level of product contaminated.

Today, the pharmaceutical departments of hospitals have still manufactured intravenous solution by backward equipments to use in hospital including the central hospitals. Therefore, the problem that using and supply the solutions, is anxiety of many person include health staffs and patients in areas when used such self supplied products.

OBJECTIVE: Analyze and conclude the new quality control process, so as to improve the quality control efficiency. METHODS: Statistical analysis was conducted on the flow rate quality control data of infusion pump in 2020, with a total of 330 times of quality control data. RESULTS: The pump with qualified flow rate entered and maintained the qualified state from the third minute, while the pump with unqualified flow rate entered and maintained the unqualified state from the second minute. CONCLUSIONS Take the third minute to enter the qualified range and continue for 2 minutes to judge that the flow rate quality control is qualified. The accuracy of this new rule is as high as 100%, and the time of flow rate quality control can be reduced from 60 minutes to 10 minutes, which greatly improves the work efficiency.

A comparison test on the number of puncture coring is conducted using the normal needle and the Huber needle in the injection area of the implantable drug-supplying device separately. The result indicates that the number of coring using the Huber needle is much less than that using the normal needle during the puncturing. So it is suggested to popularize the Huber needle in the drug transfusion of the implantable drug-supplying device.

To evaluate the influence of different brands of syringes on performance parameters and application quality of syringe pump, we carried out matching experiment of infusion/syringe pump analyzer Rigel Multi-Flo, made by ALK Co. in Sweden, for 3 different types of syringes to measure the flow rate, occlusion alarm pressure, occlusion time and bolus volume of 26 syringe pumps. Data of quality control were analyzed with statistical method. The results demonstrated that there were significant differences in the flow rate, occlusion alarm pressure, occlusion time and bolus volume (P<0. 01) between those of common syringes and original syringes. This study points out that the health care providers should select compatible syringes for syringe pumps, which provides evidence and guidance to assure the reasonable and safe application of syringe pumps in clinical practice.

BACKGROUND: In dental intravenous sedation, continuous intravenous infusion of a low-dose drug requires an infusion pump such as a syringe pump. To develop a new syringe pump for clinical use, the functions of the pump must meet certain international standards. Various safety and efficacy tests must be performed on the syringe pump, as stipulated by these standards, and an approval must be received from the approving agency based on such test results. METHODS: The authors of the present study developed a novel syringe pump and performed efficacy evaluation by testing its infusion speed at 1 and 25 ml/h, and infusion performance testing at 2 and 24 h. Moreover, performance evaluation was conducted by comparing the novel pump to an existing pump with the infusion speed varied from 1 to 5 ml/h. RESULTS: In the efficacy testing on the newly developed syringe pump, infusion with the infusion speed initially set to 1 ml/h resulted in infusion speeds of 1.00 and 0.99 ml/h in the 2- and 24-h assessment, respectively. Changing the infusion speed setting to 25 ml/h resulted in an infusion speed of 25.09 and 23.92 ml/h in the 2- and 24-h assessment, respectively. These results show no significant differences when compared with other commercially available pumps. CONCLUSIONS: The efficacy testing of the newly developed syringe pump showed the accuracy to be within tolerance. Based on these findings, we believe that the newly developed syringe pump is suitable for clinical use.

The clinical application value of infusion pumps dedicated infusion device was evaluated through the comparison on the accuracy between dedicated and non-specific infusion devices. Experiments were conducted by using five test points each repeated three times to detecting accuracy of the infusion of the three kinds of infusion devices. Through the analysis of test results, we found out that the infusion accuracy of special and non-dedicated infusion devices in the experiment, exists significant differences (P < 0.05), and we believe that the use of infusion pumps dedicated infusion device can guarantees safety and reduces medical risks in clinical.

PURPOSE: Evaluation of the effects of a vehicle's movement/ operation on fluid flow regulators during patient transport. To determine whether or not vehicle trembling during idling and movement during patient transport are factors affecting the velocity of fluid injection. METHODS: The volume of fluid, as measured in an idling or moving vehicle, was evaluated using three different types of marketed flow regulators at three different injection speeds: 10, 20 and 40 ml/hr. RESULTS: In all cases, when the vehicle was idling or in motion, discrepancies were observed between the pre-calculated amount of fluid and the actual amount of fluid injected. However, a greater discrepancy was observed to exist in a moving vehicle. CONCLUSION: The trembling and movement of a vehicle during patient transport affects fluid injection results.

BACKGROUND: Many infusion devices have been used in anesthetic practice, some of them are balloon type infusor consisted of rubber or silicone materials. This study was done on the basis of that the flow rate will vary according to the volume of balloon type infusor because the shape and elasticity of the balloon is changed. METHODS: We examed infusor-A consisted of silicone (n=15) and Infusor-B consisted of rubber (n=15). Each model was 2 ml/h, total volume 100 ml type. The infusor was filled with normal saline 100 ml and the inside pressure of the infusor was measured according to the reservoir volume change. Infusion rate was calculated by dividing the infused volume by infused time. The infused volume was measured by the weight reduction of the reservoir. RESULTS: The monitored inside pressure of the reservoir was divided into 3 ranges; the range of the pressure decreasing (100-85 ml), maintaining (85-8 ml), and increasing (8-0 ml) with the infusor volume. The flow rate varied with the infusor volume; in the large (100-85 ml) and small (8-0 ml) infusor volume, the infusion rate was higher than other volume range (85-8 ml). CONCLUSIONS: In the balloon type infusor, the inside pressure of the balloon reservoir was not sustained evenly in the total reservoir volume range. But the infusion rate was parallel with the inside pressure of the reservoir and influenced by the reservoir volume. This may be owing to the change of the elasticity and tensile force of the reservoir according to the time and volume.
