Abstract
An oral-nasal protective cover matched with an insertion instrument for use comprises a protective cover body, a pair of retaining rings and an elastic protective film; the protective cover body is provided with a hole, and a pair of retaining rings are tightly matched on the hole; an elastic protective film is clamped between the pair of retaining rings; the elastic protective film is provided with a small hole, and the diameter of the small hole is smaller than that of the insertion instrument. A protective film is pasted on the small hole of the elastic protective film. The protective cover body is an international standard mask. The utility model is a protective sleeve which is used in cooperation with the sample collection or operation which needs to use an endoscope or other instruments and enters from the oral cavity or the nasal cavity. After the endoscope and other inserted instruments enter the small hole, the elastic membrane wraps the outer wall of the instrument, so that the phenomenon of air leakage cannot be caused. The utility model discloses effectively avoided the person of examining to propagate the infection source for other contacters in medical personnel and the environment through the respiratory track to do not influence the person of examining to breathe, it is simple and convenient to use.
Description
Technical Field
The utility model belongs to the technical field of medical equipment, concretely relates to mouth nose protection casing that cooperation insertion instrument used.
Background
The insertion instruments such as endoscopes can enter the digestive system and respiratory system through mouth and nasal cavity or enter the body through other natural orifices. Since a lesion which cannot be displayed by X-ray can be seen by an endoscope, it is very useful for a doctor. For example, with the aid of an endoscopist, an ulcer, hemorrhage or tumor in the stomach can be observed, sampled, subjected to minimally invasive surgery or an optimal treatment can be made based thereon.
The traditional method uses an insertion instrument such as an endoscope and the like to directly observe the oral cavity of a patient by medical staff, and the exhaled droplets and aerosols of the patient are one of the main transmission ways of pathogens (such as novel coronavirus). Therefore, the prior art has higher infection risk for nursing personnel and surrounding waiting personnel during the process of using the endoscope.
Disclosure of Invention
The utility model aims to solve the technical problem that an oronasal protection casing that the cooperation was inserted the apparatus and is used is provided, reduces or avoids when carrying out oral cavity sample collection or operation, and the patient will infect the source and spread for medical personnel through the respiratory track.
The utility model discloses a realize like this:
an oral-nasal protective cover matched with an insertion instrument for use comprises a protective cover body, a pair of retaining rings and an elastic protective film; the protective cover body is provided with a hole, and the pair of retaining rings are tightly matched on the hole; the elastic protective film is clamped between the pair of retaining rings; the elastic protective film is provided with a small hole, and the diameter of the small hole is smaller than that of the insertion instrument.
Furthermore, a protective film is attached to the small hole of the elastic protective film.
Further, the protection casing body is the international standard gauze mask.
Furthermore, the inner retaining ring of the pair of retaining rings close to the oral cavity and the nasal cavity is connected with the mouthpiece accessory into a whole, so that the inserting device is prevented from being bitten by the examinee while respiratory infectious diseases are prevented.
The utility model has the advantages that: the utility model is a protective sleeve which is used for sample collection or operation which needs to use an endoscope or other insertion instruments and enters from the oral cavity or the nasal cavity. After the insertion instruments such as the endoscope enter the small hole, the elastic protective film wraps the outer wall of the insertion instruments such as the endoscope, so that the phenomenon of air leakage cannot be caused. A protective film is stuck to the middle hole of the elastic protective film, and the protective film is stuck to the elastic protective film before an inserter such as an endoscope enters the oral cavity to prevent an infection source from being exhaled from the small hole. When it is necessary to insert an insertion instrument such as an endoscope into the mouth of a patient, the protective film is torn. The utility model discloses when guaranteeing by examiner's normal breathing, effectively avoided the patient to propagate the infection source for medical personnel and other examined personnel through the respiratory track, need not special environment such as laminar flow ward can normally carry out the endoscope and diagnose to it is very convenient to use.
Drawings
The invention will be further described with reference to the following examples with reference to the accompanying drawings.
Fig. 1 is a schematic view of the exploded structure of the present invention.
Fig. 2 is a schematic view of the overall structure of the present invention.
Detailed Description
As shown in figures 1 and 2, the mouth-nose protective cover used with an insertion instrument comprises a protective cover body 1, a pair of retaining rings 21 and 22 and an elastic protective film 3.
The protective cover body 1 can be an international standard mask, a hole 11 is arranged on the protective cover body, and a pair of retaining rings 21 and 22 are tightly matched on the hole 11; an elastic protective film 3 is clamped between the pair of retaining rings 21 and 22; the elastic protective film 3 is provided with a small hole 31, and the diameter of the small hole 31 is smaller than that of the insertion instrument. After the insertion instrument enters the small hole 31, the elastic protective film 3 will wrap the outer wall of the insertion instrument, so that the phenomenon of air leakage can not be caused.
A protection film 4 is adhered to the small hole 31 of the elastic protection film 3. A protective film 4 is attached to the elastic protective film 3 at the central hole, and the protective film 4 is attached to the elastic protective film 3 before the insertion instrument enters the oral cavity or nasal cavity to prevent the infectious agent from being exhaled from the small hole 31. When it is desired to insert an instrument or an endoscope into the mouth of a patient, the protective film 4 is torn.
In practice, the inner clasp 21 of a pair of clasps near the oral nasal cavity may be integrated with a mouthpiece attachment (not shown) for protection against respiratory tract infections while also preventing the insertion device from being bitten by the subject.
The utility model is a protective sleeve which is used for sample collection or operation which needs to use an endoscope or other insertion instruments and enters from the oral cavity or the nasal cavity. After the insertion instruments such as the endoscope enter the small hole 31, the elastic protective film 3 is wrapped on the outer wall of the insertion instruments such as the endoscope, so that the phenomenon of air leakage cannot be caused. A protective film 4 is attached to the middle hole of the elastic protection cover 3, and the protective film 4 is attached to the elastic protection cover 3 before an insertion instrument such as an endoscope enters the oral cavity to prevent the infection source from being exhaled from the small hole 31. When it is necessary to insert an insertion instrument such as an endoscope into the mouth of a patient, the protective film 4 is torn. The utility model discloses effectively avoided the person of examining to propagate the infection source for other contacters in medical personnel and the environment through the respiratory track to do not influence the person of examining to breathe, it is simple and convenient to use. When the insert contains an endoscope, the endoscopic image also effectively guides the insertion process with visual assistance.
The above embodiments and drawings are not intended to limit the form and style of the present invention, and any suitable changes or modifications made by those skilled in the art should not be construed as departing from the scope of the present invention.
