As shown in fig. 1, a mask for protecting a patient with an endotracheal tube comprises: comprises a protective part 10, fixing parts 20 arranged at two ends of the protective part, and a connecting part 30.
The protective part 10 is used for covering the mouth and the nose of a patient to avoid viral particles from leaking. The protection part 10 includes several filter layers, such as a coarse filter layer and a fine filter layer, which can filter and adsorb virus particles. The fine filter layer is used for carrying out the finest filtration, and a microporous filter layer can be selected, such as PTFE or PET, and the like is preferred; the coarse filter layer can be selected from coarse filter materials such as non-woven fabrics, gauze and active carbon.
One side of the protection part 10 is provided with a movable opening 11 (which can be arranged at any side, near the nose side or near the mouth), and the movable opening 11 comprises a first movable end 111 and a second movable end 112. The first movable end 111 and the second movable end 112 are movably connected and hermetically fixed by the connecting member 30.
The fixing piece can be selected from a suspension loop type or a strap type.
To facilitate the fixing of the patient by the nursing staff, the fixing member 20 is preferably provided as a strap type, the left and right straps (or a soft rope) have different lengths, and a longer strap can be wound around the back of the brain of the patient to be tied to the neck side.
The connecting member 30 may be a double-sided tape or a hook and loop fastener. The magic tape comprises a hair face part and a hook face part.
Example 1
The first movable end 111 and the second movable end 112 are respectively provided with a hook surface portion and a hair surface portion. When the mask with the pollution failure worn by the patient with the tracheal cannula needs to be replaced, the movable opening 11 is opened, for example, the first movable end 111 and/or the second movable end 112 are pulled open to be sleeved around the trachea, then the hook surface part and the hair surface part of the first movable end 111 and the second movable end 112 are correspondingly adhered and fixed, and the first movable end 111 and the second movable end 112 are movably sealed around the trachea to avoid the risk of aerosol or body fluid leakage to the maximum extent, as shown in fig. 2.
Example 2
As shown in fig. 3, the first movable end 111 is fixed (e.g., sewn) to one end of the connecting member 30, and the other end of the connecting member 30 and the second movable end 112 are respectively provided with a hair portion and a hook portion, so that the two can be fixed when sealing is required. When the mask with the pollution failure worn by the patient with the tracheal cannula needs to be replaced, the movable opening 11 is opened, if the first movable end 111 and/or the second movable end 112 are pulled open, the mask surrounds the trachea 1 in a sleeved mode, then the hook face portion and the hair face portion of the connecting piece 30 and the second movable end 112 are correspondingly adhered and fixed, and the first movable end 111 and the second movable end 112 are movably sealed around the trachea to avoid the risk of aerosol or body fluid leakage to the maximum extent.
Example 3
As shown in fig. 4, the first movable end 111 and the second movable end 112 are respectively provided with a recess near the center of the protection part 10, and the two recesses are not connected and can be combined to form a through hole 113 for housing an air tube. The aperture size of the through hole 113 is equal to or slightly smaller than the diameter of the trachea, so that the face of the patient can be more conveniently and tightly coated.
Example 4
The connecting member 30 is a double-sided tape (not shown) used in combination with a mask for protection. As shown in fig. 1, the mask for protection comprises a protection part 10 and a fixing part 20, wherein a movable opening 11 is disposed at one side of the protection part, and the movable opening 11 comprises a first movable end 111 and a second movable end 112. When the mask with the pollution failure worn by the patient with the tracheal cannula needs to be replaced, the movable opening 11 is opened, for example, the first movable end 111 and/or the second movable end 112 are pulled open, the mask is sleeved around the trachea 1, then the double-sided adhesive is adhered to the lower surface of the end part of the first movable end 111, and the outer surface of the double-sided adhesive is adhered to the upper surface of the second movable end, so that the first movable end 111 and the second movable end 112 are fixed around the trachea, and the risk of aerosol or body fluid leakage is avoided to the maximum extent.
In order to facilitate the operation, a double-sided adhesive tape may be reserved on the first movable end 111, and when the device is used, after the first movable end 111 and the second movable end 112 surround the trachea, the release film is privately removed, so that the adhesive layer of the double-sided adhesive tape is adhered to the second movable end, and the purpose of sealing and fixing is achieved. Therefore, the respirator pipeline does not need to be disconnected when the mask is replaced, the virus-containing aerosol can be greatly reduced from being sprayed, and nosocomial infection is avoided.
To make the wrapping more compact and to minimize the escape of aerosols or body fluids, a layer of resilient material (not shown) may be provided on the side wall of the first movable end 111 opposite the second movable end 112.
In some embodiments, the magic tape can be used in combination without being connected with the protective part as a connecting piece.
The special mask provided by the utility model does not need a special production line, and can be realized by simply processing the existing respiratory system diseases, especially infectious disease protective masks, such as disposable medical surgical masks or N95 masks. Or simply changing the existing mask production line.
To sum up, the technical idea of the present invention is to uniquely provide a solution from the perspective of reducing the possibility of aerosol or leakage of patients in order to improve the safety protection of medical personnel. The utility model provides a special gauze mask of protection for trachea cannula patient supplies the patient to wear, and the activity opening of its setting can conveniently be opened or airtight, can guarantee the airtight effect of gauze mask effectively, and convenient replacement, low cost uses the scene good.
While the present invention has been described in detail with reference to the preferred embodiments thereof, it should be understood that the above description should not be taken as limiting the present invention. Numerous modifications and alterations to the present invention will become apparent to those skilled in the art upon reading the foregoing description. Accordingly, the scope of the invention should be limited only by the attached claims.
