PATIALA: Researchers at the Indian Institute of Technology (IIT), Ropar has developed electronic massage for calf muscles that can reduce the risk of fainting between blood donors during or after blood donation.
According to them, an adult contributed 450ml of blood, which is about 10% of the volume of blood, which is considered safe and usually does not cause adverse effects.
However, rarely, donors can experience side reactions during or after contributions such as weakness, dizziness, cold sweat, fainting and other symptoms.
It has been seen by the maximum donor that their blood pressure can go down or the heartbeat slows suddenly and donors may feel fainted, nausea, or light-headed or, in some cases, loss of consciousness.
The researchers said this work was carried out in collaboration with the Department of Transfusion Medicine from the Institute of Education and Medical Research (PGI) Postgraduate (PGI), Chandigarh.
The clinical trial of this device is being carried out under the supervision of Dr.
Suchet Sachdev from PGI.
The massager developed by IIT Ropar has a programmed circuit that can control the vacuum pump so that it can expand and deflate cuffs synergistically.
This can relax blood donors so as to reduce anxiety before blood donation and thus transfer from the triggers of blood donors and improve peripheral blood circulation so as to improve blood circulation to the heart.
“It is expected to reduce the risk of vasovagal syncope (dizziness, nausea, and fainting),” said Ashish Sahani, assistant professor, the biomedical engineering department.
“This device is simple, safe and portable to reduce the incidence of vasovagal syncope in blood donors.
It is non-invasive and non-pharmacological.
It works only by giving a massage on the donor calf muscles so that it pumps back blood collected to the heart that can improve Heart pulse and heart contraction, where blood is pumped into a donor blood pressure artery and also prevents mental transfer that can avoid triggering vasovagal syncope.
This device can help in reducing the drop-out level of blood donor due to vasovagal reaction, “explained Sahani.
Ravinder Kumar, scholar research, biomedical engineering, IIT Ropar said, “This device ideally will be installed on the blood donor chair itself.
To operate this device, low pressure sets are governed by the operator and then the device is turned on.
Cufflinks begin to end and de Clap According to the pressure ceiling set by the knob.
The set-point is increasing slowly until someone can feel a relaxed massage effect on the calf muscle.
If the pressure setpoint is set too high, the patient may feel uncomfortable and in this case the setpoint must be reduced by the appropriate control signal Through the knob.
After this blood donor process starts.
After the donation is complete, the device is turned off and the cuff is removed.
“He added,” Dizziness, nausea, and fainting is why people find unpleasant blood donors.
This device can make them feel pleasant when contributing and Afterwards.
