The embodiment needs to be explained as follows:
an air inlet pipe 3 and an air outlet pipe 4 are connected between the respirator 2 and the hood 1, wherein the air inlet pipe 3 is used for conveying air used for breathing in a positive pressure mode; the air outlet pipe 4 is used for exhausting the exhaled air of the wearer. Therefore, the risk of cross infection between doctors and patients can be reduced, and the safety of medical personnel is ensured.
The two sides of the respirator 2 are provided with straps 7. Through the design of braces 7, can make things convenient for the wearer to wear.
The respirator 2 comprises a respirator body 22, a filter box 21 and a battery; the filter box 21 and the battery are both mounted on the respirator body 22. The filter box 21 is used for filtering air entering from the outside; the entire respirator 2 is powered primarily by batteries.
The respirator body 22 is also provided with a blower, wherein the blower is powered by a battery, sucks air from the surrounding atmosphere, and delivers the clean air to the hood 1 through the air inlet pipe 3 after being filtered by the filter box 21.
An air outlet one-way valve 5 is arranged in the connection part of the air outlet pipe 4 and the head cover 1; and an air inlet one-way valve 6 is arranged at the joint of the air inlet pipe 3 and the head cover 1. The effect of this design is: the air inlet one-way valve 6 enables the outside air flow to enter the hood 1 for breathing, and the air outlet one-way valve 5 enables the exhaled air flow of the wearer to be discharged from the air outlet pipe 4 independently. The respiratory airflow and the exhaling airflow are independent from each other, and the cross infection is reduced.
The filter box 21 comprises a front cover 211, a particulate matter filter 212 and a gas filter 213; the particulate filter 212 is provided with a front cover 211 on the outer side and a gas filter 213 on the inner side. Wherein, the particulate filter 212 is used for filtering dust in the air; the gas filter 213 is used to purify and filter air.
The particle filter sheet 212 and the gas filter sheet 213 are designed to have arc surfaces. Wherein, the design of arcwall face, relative planar design has increased area of contact like this, and the air current filtration volume in the unit area is big.
The number of the gas filter sheets 213 is two. Wherein, adopt double-deck filtration, it is good to the purifying effect of air.
The head cover 1 comprises a head covering part 11 and a face covering part 12; the head covering part 11 is arranged at the lower edge of the face covering part 12; the internal channels of the head covering part 11 and the face covering part 12 are communicated. The head and abdomen part is used for covering the head of a wearer, the face covering part 12 is used for sealing the face of the wearer, and the internal channels in the head covering part 11 and the face covering part 12 are designed to be communicated with each other, so that the exchange of respiratory airflow is facilitated.
The head cover is made of cotton materials; the covering part 12 is made of transparent material. Wherein, the cotton material is adopted, so that the softness is good; and the transparent material is adopted, so that the observation is convenient.
The air outlet one-way valve 5 comprises a valve body 51 and a valve plate 52; one end of the valve body 51 is connected with a valve plate 52, and the valve plate 52 is converged into a point in a natural state and forms a funnel shape with the valve body 51. The effect of this design is: the valve plate 52 is arranged in a closed state from a natural state, so that outside airflow cannot enter, and when a wearer exhales airflow, the valve plate 52 is opened under the action of air pressure, so that the exhaled airflow is discharged, the independent air flow discharge is realized, and the design is ingenious.
The air inlet one-way valve 6 comprises a shell 61, a fixing rod 62, a sealing membrane 63 and a limiting ring 64; the fixing rod 62 is positioned in the center of the shell 61; the fixed rod 62 is movably connected with a sealing membrane 63; the upper edge of the sealing membrane 63 is provided with a limiting ring 64. The effect of this design is: when in the air inlet state, air pressure acts on the sealing diaphragm 63, the sealing diaphragm 63 is inclined after being pressed, and a gap is formed between the sealing diaphragm 63 and the inner wall of the shell 61, so that air inlet is facilitated; if the air flow in the hood 1 acts on the sealing membrane 63, the sealing membrane 63 will abut against the limiting ring 64 to achieve the sealing effect, so that the air flow in the hood 1 cannot be discharged.
An oxygen supply pipe is also arranged between the head cover 1 and the respirator 2. Wherein, can put into the oxygen bag in respirator 2, this oxygen bag is used for and supports union coupling, has realized carrying out the oxygen suppliment operation to the person of wearing to effectual oxygen deficiency prevention.
The utility model discloses a hospital feels protective helmet can realize independently admitting air and giving vent to anger, can reduce the cross infection risk between the doctor and the patient, ensures medical staff safety, can become a neotype medical instrument product, has extensive application prospect in clinical popularization.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and additions can be made without departing from the principles of the present invention, and these improvements and additions should also be regarded as the protection scope of the present invention.
