Not many people like injections. For children, injections may bring special trauma, because fear will make what might have been only a brief scratching become worse. Fortunately, there is a potential solution, because doctors are using virtual reality (VR) as a means to relieve fear and make those injections less likely to end in trauma.
Prior to this, people have noticed that VR can be used to combat the anxiety and pain of robots. Medical staff at General Hospitals in the North of England use this technology to help patients distract, and American pediatricians believe that this idea may be beneficial to children help.
Chad Rudnick, founder of Bokawi Pediatrics, said: “When an 8-year-old patient walked into his office with a VR helmet, the child did not even flinch at the time of the injection. He was inspired and decided to use VR for Distraction therapy."
Although VR is widely used in healthcare, there is no specific research on the use of VR for childhood immunizations, so Rudnick tested his theory with the help of two medical students. The two medical students are also co-authors of the study, Emaan Sulaiman and Jillian Orden, who are members of the Charles E. Schmidt School of Science at FAU.
Participants in this study were between 6 and 17 years old, and they completed a pre- and post-questionnaire that assessed their pain, fear, and anxiety levels. Rudnick used a 3D VR helmet with a smartphone app to let the children choose to ride a roller coaster, a helicopter, or a hot air balloon. Children can enjoy a short VR experience during the injection.
The results showed that pain and fear of 94.1% of the study subjects were reduced.
Reverse Conducting Thyristor(RCT)
Reverse Conducting Thyristor(RCT) is also called Reverse- appreciation Thyristor.The characteristic is that a diode is connected in reverse parallel between the anode and cathode of thyristor, so that the transmitting junction of anode and cathode is short-circuited.As a result of this special circuit structure, it has high voltage resistance, high temperature resistance, short turn-off time, low switching voltage and other good performance.For example, the turn-off time of the reverse thyristor is only a few microseconds, and the working frequency is dozens of KHZ, which is better than the fast thyristor (FSCR).This device is suitable for switching power supply and UPS uninterrupted power supply. One RCT can replace one thyristor and one continuous current diode respectively.
