[0006] BACKGROUND

[0007] There are several types of respiratory protective systems present. Several types of such systems are currently available on the market for use in surgical areas, in “clean room” environments, or in hazardous or contaminated environments. The surgical helmet system is a personal protection system in healthcare with operating theatres during surgical procedures to provide a sterile barrier between the surgical personnel and the patient. During operation or surgical procedures, it is possible that blood, bodily fluids, bacteria, viruses and air borne pathogens and particles may travel or splash from the patient to the surgeon. It is also possible that certain fluids and particles, such as sweat drops and hair, can fall from the surgeon into the surgical site of the patient. Exhaled air from the surgeon or support staff in the operating theatre, could also trigger infections. Also, during hip or knee replacement, surgeries are prone for infection, hence needs extremely sterile operation theatre environment. Currently existing protection systems includes helmet, protective sterile surgical hoods, integral gown, and the like. The existing protective systems does not provide overall protection and are costly. Also, the existing helmets are having chin bar which restricts movement of the wearer. Further, the existing systems are heavy in weight and are unergonomic hence are not comfortable to wear for log duration in case of complicated surgery.

[0008] There is need of a protective system that is light, ergonomic and comfortable to wear for long duration surgeries. Also, there is a need for a system that eliminates expensive battery charging units. Further, there is a need for a system which is flexible to adjust according to head size of the wearer.

[0009] Hence, there is a need for a surgical helmet system and a method for operating the same that addresses the aforementioned issues.

[0010] OBJECTIVE OF THE INVENTION

[0011] An objective of the present invention is to design a surgical helmet system to protect the medical professionals.

[0012] Another objective of the present invention is to eliminate the presence of a chin bar thereby reducing the weight of the surgical helmet system and allowing a user to move his / her head freely during the act of wearing the surgical helmet system.

[0013] Another objective of the present invention is to eliminate expensive battery charging units and making the surgical helmet system lightweight.

[0014] Yet, another objective of the present invention is to provide comfort to the user when used for long time.

[0015] Further, an objective of the present invention is to provide adjustable helmet based on the size and shape of the head of the user.

[0016] Furthermore, an objective of the present invention is to protect the user from small particles such as bone debris and particulate matter or filter the cautery smoke. Furthermore, an objective of the present invention is to protect patients from exhaled air from surgeons hence avoid post-surgery infections.

7. The surgical helmet system (100) as claimed in claim 1, wherein the at least two fastening mechanisms (106a, 106b) are Velcro fasteners or an optional fastening mechanism.

8. The surgical helmet system (100) as claimed in claim 1, comprises a power bank for providing energy to the at least one fan (114).

9. A method (200) for operating the surgical helmet system comprising: providing, a headband of a helmet assembly for mounting along circumference of head of a user; (202)arranging, at least two projections on the opposite sides of the headband and positioning at a proximal end to the ears of the user, wherein the at least two projections are inversely angulated; (204) accommodating, by the at least two projections of the head band of the helmet assembly, at least two fastening mechanisms or an optional fastening mechanism; (206) mounting, a housing unit of the helmet assembly, on a top portion of the head of the user; (208) providing, an aerodynamic shaped structure in contact with a top portion of the head of the user; (210) providing, by a plurality of grills of the aerodynamic shaped structure, ventilation to the user; (212) filtering, by a filter of the aerodynamic shaped structure, smoke that enters into the grill structure from the external air; (214) regulating, by a switch of the housing unit, the airflow; (216) replacing, a chin bar by an inverted T- shaped structure extend from an inclined portion of the aerodynamic -shaped structure; (218) adjusting, by a knob of the control unit, the circumference of the headband based on the size of the user’s head; (220) adjusting, by a height-adjustable connector of the control unit, the height of the housing unit in response to a user pressing a push button; (222) detachably connecting, a sterile surgical hood with the at least two fastening mechanisms and mounting atop the aerodynamic shaped structure; (224) engaging, a visor via the hook configured on the inverted T-shaped structure; (226) andproviding, a slot for engaging with the housing unit and configured to place at a predefined distance from the face of the user to allow air circulation.
