Description

Medical protective helmet with replaceable face screen

Technical Field

The utility model relates to a personal protection field and medical field, concretely relates to medical protective helmet of removable face screen.

Background

In the infection room that carries the virus, medical personnel often are infected because the protection is inefficacy, and the face screen of especially helmet class protective equipment among most protective equipment is mostly for being difficult for wasing and changing, has reduced protective equipment's reuse rate, and wears for a long time that the remaining germ of face screen can increase medical personnel's infection rate, for reducing helmet class protective equipment's use cost, reduces medical personnel's infection rate, the utility model relates to a medical protective helmet of removable face screen.

Disclosure of Invention

The utility model discloses a purpose design is a medical protective helmet of removable face screen.

The functions of the device are realized by the following technical scheme:

a medical protection helmet with a replaceable face screen comprises the replaceable face screen, an elastic apron, fixing round holes, face screen buckles, a helmet body, an elastic knob, an airflow pipeline, a centrifugal fan, a filter screen cover and an external power supply port. The method is characterized in that: the helmet body top be provided with centrifugal fan, centrifugal fan connect the air current pipeline, helmet body front surface be equipped with the face screen buckle, removable face screen dig three fixed round hole, fixed round hole buckle on the face screen buckle, removable face screen even have the elasticity apron through cold stamping, helmet body rear portion be equipped with external power supply port.

Further, the centrifugal fan is installed at the top of the helmet body.

Further, the filter screen cover is a device capable of replacing the filter element, and the filter layer disinfection device is placed at an inlet of the centrifugal fan.

Furthermore, the face is covered by the replaceable face screen and the elastic apron to form a positive pressure area.

Further, the tightness degree of the head strap can be adjusted through the tightness knob.

Furthermore, the external power supply port can be connected with a mobile charging power supply.

The centrifugal fan (8) is driven by the current of the power supply of the external power supply port (9) to absorb external unclean airflow, the unclean airflow passes through the filter screen cover (7), the airflow is filtered and sterilized, and clean and comfortable breathing airflow is provided for a user through the airflow pipeline (4).

The beneficial effects of the utility model

The utility model provides a medical protective helmet of removable face screen ensures that medical personnel can keep apart the bacterial virus more effectively to provide clear respiratory airflow, reduce the infection rate.

The utility model discloses make helmet class protective apparatus's face screen can dismantle, make things convenient for the person of wearing to disinfect and change, reduce use cost and avoid medical personnel to be infected because of there is remaining germ at the face screen as far as possible.

Drawings

Fig. 1 is an overall three-dimensional structure diagram of the present invention.

FIG. 2 is an enlarged view of a portion of a face shield clip of the replaceable face shield.

Fig. 3 is a schematic view of the structure of the replaceable panel.

In the figure: 1. the elastic apron comprises an elastic apron body, 2 parts of a replaceable face screen, 3 parts of a fixing circular hole, 4 parts of an airflow pipeline, 5 parts of a helmet body, 6 parts of a face screen buckle, 7 parts of a filtering net cover, 8 parts of a centrifugal fan, 9 parts of an external power supply port, and 10 parts of an elastic knob.

Detailed Description

Example 1: referring to fig. 1, the present invention provides a medical protective helmet with a replaceable face screen, which comprises: the detachable helmet comprises an elastic apron 1, a replaceable panel 2, a fixing round hole 3, an airflow pipeline 4, a helmet body 5, a panel buckle 6, a filter screen cover 7, a centrifugal fan 8, an external power supply port 9 and an elastic knob 10. The face-replaceable air flow filter is characterized in that when the centrifugal fan 8 works, outside dirty air is sucked in, and the air enters a space formed by the face-replaceable screen 2 and a human face through the filter screen cover 7 and the air flow pipeline 4, so that clean and comfortable safe air flow is provided for medical staff.

Example 2: please refer to fig. 2 and fig. 3, the utility model relates to a medical protective helmet of removable face screen, removable face screen 2 upper portion dig three fixed round hole 3, three fixed round hole 3 and the three face screen buckle 6 of the helmet body 5 front surface link to each other with fastening respectively, the disinfection and the change of person of facilitating the use to the face screen reduce medical personnel's infection rate.
