Compared with the prior art, the utility model, have and to realize negative pressure and keep apart, can realize the advantage of negative pressure fog inhalation again.
Description
The technical field is as follows:
the utility model relates to a nursing apparatus.
Background art:
along with the outbreak of novel coronavirus, more and more new coronary pneumonia patients need treat, in order to avoid the infection, during the treatment, generally be medical personnel and wear good complete protective clothing after, carry out the outbreak of fulminating infectious diseases such as treatment to the patient in special medical care room and bring very big risk for first-line medical personnel, when implementing atomizing treatment for this type of patient, can lead to the infection risk to increase because aerial fog production aerosol releases the pathogen in to the environment. How to atomize patients and prevent aerosol from diffusing to the surrounding environment, and reduce the risk of infection of medical staff is one of the problems to be solved urgently. The negative pressure atomization device can establish a stable negative pressure environment around the atomizer, and a patient can inhale atomized medicine, but air with pathogens is sucked, filtered and discharged into the air, so that the chance of infection of medical staff is reduced.
The existing 'negative pressure air isolation cover' and 'negative pressure isolation hood' are only technologies for extracting air under negative pressure, and cannot realize atomization treatment under the negative pressure environment.
The invention content is as follows:
an object of the utility model is to provide a can realize negative pressure and keep apart, can realize the treatment of negative pressure fog inhalation again and use protection hood.
The utility model discloses a realize like this, include the guarantor's type hood that covers the head front portion is sealed, the setting is at guarantor's hood rope binding all around, its special character lies in the middle part protrusion that the guarantor's type hood forms the bulge, the outer convex that the inner chamber that makes this bulge forms the department of the mouth nose that corresponds with the face of the person, be provided with all around of the inner chamber of this bulge and lean on to facial flange, the bulge is provided with the air guide hole that has the pipeline interface in the department of corresponding nose, be provided with the export of being connected with the air duct near guarantor's type hood edge, the export of leading passes through the air duct and links to each other with the negative.
When the air suction hood is used, oxygen or atomized medicine is introduced through the air guide holes so as to be absorbed by a patient, the negative pressure suction device sucks air in the hood, the hood forms negative pressure, the air in the hood is prevented from overflowing and polluting surrounding air, and when the air in the hood is sucked, the sucked air is filtered and sterilized through the filtering and sterilizing device and then is discharged. The periphery of the inner cavity of the protruding part is provided with a flange leaning against the face, so that oxygen or atomized medicine guided from the air guide hole is prevented from flowing to the guide outlet rapidly and not being sucked by a patient, meanwhile, a gap is reserved between the flange and the face of the patient, and air exhaled by the patient can enter the hood through the gap and is guided out from the guide outlet.
Compared with the prior art, the utility model, have and to realize negative pressure and keep apart, can realize the advantage of negative pressure fog inhalation again.
Description of the drawings:
fig. 1 is a schematic structural view of the present invention;
FIG. 2 is a side view of the present invention;
fig. 3 is a sectional view a-a of fig. 2.
The specific implementation mode is as follows:
the present invention will now be described in further detail with reference to the accompanying drawings and examples:
as shown in figures 1 and 2, the head protecting hood comprises a head protecting hood 1 for hermetically covering the front part of the head of a person and binding ropes 2 arranged on the periphery of the head protecting hood 1, so that tension is applied to the head protecting hood 1 through the binding ropes 2 to enable the bottom edge of the head protecting hood 1 to abut against the skin of the front part of the head of the person to form sealing contact, and the head protecting hood is characterized in that a convex part 10 is formed in the middle of the head protecting hood 1 in a protruding mode, an inner cavity of the convex part 10 forms an outer convex shape corresponding to the mouth and nose of the face of the person, a flange 3 which is close to the face is arranged on the periphery of the inner cavity of the convex part 10, an air guide hole 5 with a pipeline interface 4 is arranged below the convex part 2 corresponding to the nose, an air guide outlet 7 connected with an air guide pipe 6 is arranged on the edge close to the head protecting hood 1, and the air.
As shown in fig. 1 and 3, the flanges 3 at both sides of the upper portion of the protrusion 10 are provided with air outlets 11 formed by notches, and the outlet 7 is located at the edge of the upper portion of the shape-preserving hood 1, so that exhaust gas exhaled by a person can be smoothly guided out from bottom to top, and the exhaust gas is prevented from being retained in the shape-preserving hood 1.
The flange 3 is a soft form-retaining flange and the peripheral edge of the form-retaining hood 1 is a soft edge. The soft edge is adopted, so that the shape of the flange 3 and the shape-preserving hood 1 after being worn can be kept, the inner cavity of the bulge part 10 and the shape-preserving hood 1 are ensured to have enough space to enable air to flow smoothly, and meanwhile, the shape-preserving hood can adapt to the change of the face of different wearers.
A cushion 12 is arranged along the peripheral edge of the shape-preserving hood 1. By adopting the soft cushion 12, the edge can be ensured to be attached to the skin, and the comfort can be improved.
The shape-preserving head cover 1 with the convex part 10 is integrally formed by injection molding and is a transparent head cover which is made of TPU or PVC.
A check valve 13 is provided between the lead-out port 7 and the filter sterilization treatment device 8 or in the lead-out port 7 to prevent backflow of exhaust gas.
