Title: Robot for medical assistance

Description:
FIELD OF INVENTION 
     The present invention relates to a robot for medical assistance, and more particularly, the present invention relates to a robot for taking the vitals of a patient. 
     BACKGROUND 
     Hospital-acquired infections, also known as nosocomial infections, are infections contracted under hospital settings. Doctors and nurses who treat the patients are at a greater risk of contracting the infections. Particularly, in the intensive care units where highly infectious diseases are treated, are the source for the maximum number of hospital-acquired infections. Nurses must frequently take the vitals of the patients, which exposes them to a greater risk of contracting the infection. The nurses in turn may become a source of the spread of the infection to other patients and people. Doctors and nurses generally use face masks, gloves, or personal protective kits for protection, however, such protective kits offer limited protection. Certain infectious diseases, such as SARS or COVID-19 are highly infectious and despite all the precautions, may spread to other persons. 
     Thus, a need is appreciated for a medical aid that can assist medical professionals in taking vitals of a patient and other functions of a nurse. 
     SUMMARY OF THE INVENTION 
     The principal object of the present invention is therefore directed to a robot for medical assistance. 
     It is another object of the present invention that the robot can take vital of a patient independently. 
     It is still another object of the present invention that the robot can sanitize its body. 
     It is yet another object of the present invention that the robot can be remotely controlled. 
     It a further object of the present invention that the robot allows videoconferencing with medical staff. 
     It is an additional object of the present invention that the robot is economical to manufacture. 
     In one aspect, disclosed is a robot that can be remotely controlled for taking vitals of a patient without the need for the clinical staff to come in contact with the patient. The robot can have a face resembling the face of clinical staff, and a body and wheels. To the body of the robot can be coupled diagnostic devices positioned to be within the reach of a patient. A camera can be coupled to the face, maybe two cameras can be coupled forming the eyes of the robot. A speaker can be coupled below the eyes forming a mouth. The robot can include a central processing unit for controlling the different components of the robot and remotely connecting to other computing devices. The camera and the speakers can provide video conferring between the patient and the clinical staff. The diagnostic devices can include the blood pressure monitoring device having a cuff coupled to an outer surface of the body, such as a patient can insert his arm in the cuff. The diagnostic devices can also include a pulse oximeter and an IR thermometer.

     The disclosed robot can include diagnostic devices to take the vitals of a patient. The diagnostic devices can be operably connected to the central processing unit of the robot. The robot through the diagnostic devices can measure the vitals and transmit the same to the clinical staff device. The diagnostic devices can work in sync with the instructions on the display. The diagnostic devices can include a blood pressure measuring device for taking the blood pressure of the patient.  FIG. 1  shows a cuff  165  on the side of the body of the robot. The display can show instructions on how to insert the hand into the cuff. The position of the cuff is such that the patient can easily insert and hold his arm in the cuff for taking the blood pressure. One or more cameras can be focused on the cuff to ensure that the hand is properly positioned into the cuff. Alternatively, sensors can be used to check the cuff around the arm. 
       FIG. 1  also shows a pulse oximeter  170  configured in the body of the robot. The pulse oximeter  170  can receive the pulse rate and oxygen saturation of the patient. The pulse oximeter can also be connected to the central processing unit of the robot that can transmit the diagnostic data to the clinical staff device. Additionally, can be provided an infrared thermometer to measure the temperature of the patient. The infrared thermometer  175  can also be connected to the central processing unit of the robot that can transmit the diagnostic data to the clinical staff device. 
     The robot can have a wheelbase, such as Arduino controlled wheels that allow the robot to move around on the floor. The robot can be programmed to take the vitals of the patient at the desired time. The robot can itself move towards the patient and take the vitals. The measurements can be then sent by the robot to the clinical staff device, without the intervention of the clinical staff. Alternately, the robot can be controlled by remote control handled by the clinical staff for taking the vitals of the patient. For example, the clinical staff member, at the safe distance from the patient, can maneuver the robot towards the patient through the remote control. 
     The disclosed robot can sanitize itself for preventing the spread of infection to other patients. After getting in touch with a patient, the robot can undergo a disinfection process to remove microorganisms. For example, the robot can have inbuilt UV lamps that can irradiate the areas coming in contact with the patient. Additionally, the robot can have a layer of antimicrobial composition that can kill the microorganisms and prevent their growth. In one exemplary embodiment, the outer layer of the robot can have a network of micro-showers that apply a thin layer of disinfectant liquid on the robot&#39;s outer surface and the diagnostic devices. The network of micro-showers can be connected to a reservoir containing the disinfectant liquid.
