How Should Nurses Use These Medical Instruments?

Medical devices refer to instruments, equipment, appliances, in vitro diagnostic reagents and calibrators, materials and other similar or related items used directly or indirectly in the human body, including computer software required. Medical device adverse events refer to all kinds of harmful events that occur or may lead to human injury that occur under normal use of medical devices of qualified quality approved for marketing.



How Should Nurses Use These Medical Instruments?

Disposable Infusion Set

Disposable infusion set is mainly used for clinical gravity infusion. Adverse events that may occur during use include: chills, high fever, nausea, vomiting, infusion set leak, foreign body, etc.



Venous Indwelling Needle

Intravenous indwelling needles, also known as trocars, are soft in texture and can bend with the shape of blood vessels. They are difficult to puncture the walls of blood vessels when placed in blood vessels, which can reduce the rate of repeated puncture and reduce patient suffering. Adverse events that may occur during the use of intravenous indwelling needles include: leakage of indwelling needles (at the interface and the tail), cannula detachment, cannula blockage, cannula rupture, redness, swelling, pain, and phlebitis in the puncture site.



Urinary Catheter

Catheters are mainly used in the clinic to insert the bladder through the urethra to drain urine. Adverse events that may occur during use include: urethral swelling, pain, secretions, hematuria, low back pain, urinary catheter blockage, shedding, and balloon rupture, etc.



Infusion Pump

An infusion pump is an instrument that controls the flow rate or flow rate of a medicinal solution and inputs the medicinal solution into a patient's body through an applied pressure to achieve the purpose of treatment. Adverse events that may occur during the use of the infusion pump include: uncontrolled drip rate, inaccurate drip volume, fluid leakage, alarm failure, etc.



Medical Monitor

The monitor is an instrument used to accurately understand the changes in the patient's physical condition to reduce the workload of the hospital nurse. According to different clinical applications, the monitor is generally divided into anesthesia monitor, pulmonary function monitor, electrocardiogram monitor, and EEG monitoring instrument. The monitor may occur during use: monitoring data is inaccurate or not displayed, black screen, freezes, etc.




The ventilator is a necessary rescue device for large and medium-sized hospitals at present, it is a necessary device for the treatment of respiratory failure, rescue of critically ill patients, and anesthesia and respiratory management. It is an important tool for prolonging the life of patients and gaining valuable time for further treatment. The ventilator may occur during use: excessive tidal volume, insufficient ventilation, unstable oxygen flow, and leaks in the circuit.



Baby Incubator

Infant incubator is a kind of infant cabin that uses heated air to control the temperature of the baby's environment. It is mainly used for low-temperature infants, critically ill infants, newborns' constant temperature culture, temperature resuscitation, infusion, oxygen transfusion, rescue, hospital observation and so on. Incubation of the baby incubator may cause temperature runaway and alarm failure.



Peripherally Inserted Central Venous Catheter

The peripherally inserted central venous catheter is mainly used in supportive venous infusion therapy and blood sampling in the clinic. During use, the catheter may fall off, break and slip into the body, phlebitis, infection, and leakage after rupture of the catheter.




Sphygmomanometers are instruments for measuring blood pressure, which are mainly divided into two categories: mercury column sphygmomanometers and electronic (aneroid) sphygmomanometers. The adverse events that may occur in the use of the sphygmomanometer are mainly inaccurate measurement results, intermittent black screens, and no display of blood pressure values.




A thermometer is an instrument for measuring body temperature. There are a glass thermometer, an electronic thermometer, and an infrared thermometer. In use of the thermometer, inaccurate measurement results may occur, the mercury column does not rise or fall, and it cannot count.



Blood Glucose Meter

The blood glucose meter is a device used for self-monitoring of diabetic patients. In use, blood glucose measurement values may be inaccurate, blood glucose values may not be displayed clearly, and the screen may not be displayed.



Insulin Injection Pen

Insulin injection pen is an ideal injection device for insulin treatment of diabetic patients. The front end is an injection needle, and the sleeve on the back is filled with insulin. The size of the sleeve varies according to the type of insulin. Adverse events that may occur during the use of insulin injection pens include: pain at the injection site, leakage of the injection needle, difficulty in pushing, tight seal of the refill, and discoloration of the refill.


Many serious medical device adverse events can be life-threatening and cause death. For the safety of patients and not to hurt themselves, once a nurse friend finds that these medical devices are suspected of adverse events in clinical work, they must remember to report it! Or when an adverse event is caused by a user's operation error, it should also be reported. This is because regulatory authorities or manufacturing companies can improve product functions based on the information reported, such as modifying medical device specifications or labels, redesigning, and so on, while promoting the development and development of new products. Only in this way can we reduce or avoid the recurrence of adverse events of similar medical devices and reduce the risk of patients, medical staff or other people using medical devices.
