Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment and relates to a novel non-invasive positive pressure ventilation mask specially used for bronchoscope. Background Art

[0002] Bronchoscope is a medical device that is placed into the patient's lower respiratory tract through the mouth or nose and is used for observation, biopsy sampling, bacteriology and cytology of bronchial lesions in the lobes, segments and subsegments. It can be used for photography, teaching and dynamic recording with the TV system. The connected biopsy sampling accessories can assist in the discovery of early lesions and can be used for internal surgical operations such as polypectomy. It is suitable for bronchial and lung disease research and postoperative examinations.

[0003] The process of bronchoscopy is as follows: first insert the laryngoscope, then insert the catheter into the patient's trachea, then remove the laryngoscope, then fix the catheter, and finally perform bronchial examination and treatment.

[0004] Clinically, many patients undergo final bronchial examination and treatment after intubation. At the same time, many patients with respiratory failure require non-invasive positive pressure assisted ventilation treatment. During the final bronchial examination and treatment, if the ventilation mask is not worn for a long time, it will be detrimental to the patient's treatment.

[0005] Clinically, during the final bronchial examination and treatment, the nurse will knock a small hole in the patient's ventilation mask, put on the ventilation mask, and pass the bronchoscope catheter through the hole in the mask, so that positive pressure assisted ventilation treatment can be performed at the same time as the final bronchial examination and treatment. However, during actual use, there is a gap between the bronchoscope catheter and the hole in the mask, and gas will overflow from these gaps, greatly reducing the treatment effect. Utility Model Content

[0006] The utility model aims to solve the above problems existing in the existing bronchoscopic examination and treatment process, and proposes a ventilation mask that can perform positive pressure assisted ventilation treatment and reduce air leakage while performing the final bronchoscopic examination and treatment.

[0008] A novel non-invasive positive pressure ventilation mask for bronchoscope, characterized in that it includes a mask body and a tracheal joint and a catheter joint arranged on the mask body, the inner side of the mask body fits the human face, the tracheal joint and the catheter joint are arranged on the outer side of the mask body and are connected to the inner side of the mask body, the catheter of the bronchoscope passes through the catheter joint, and a pipe plug is also provided on the outer side of the mask body to seal the outer opening of the catheter joint.

[0009] In the above-mentioned novel non-invasive positive pressure ventilation mask for bronchoscope, there are two catheter connectors, which are arranged symmetrically on the left and right, and each catheter connector is correspondingly provided with a tube plug.

[0010] In the above-mentioned new type of non-invasive positive pressure ventilation mask for bronchoscope, one end of the tube plug is fixedly connected to the outer surface of the mask body through a connecting piece, and the connecting piece is an elastic plastic sheet. The tube plug is moved through the connecting piece to allow the tube plug to be inserted into the outer opening of the catheter connector or pulled out from the outer opening of the catheter connector.

[0011] In the above-mentioned novel non-invasive positive pressure ventilation mask for bronchoscope, the catheter connector, tracheal connector and mask body are integrally formed.

[0012] In the above-mentioned novel non-invasive positive pressure ventilation mask for bronchoscope, the inner hole size of the catheter connector is matched with the outer diameter size of the catheter of the bronchoscope.

[0013] In the above-mentioned new type of non-invasive positive pressure ventilation mask dedicated to bronchoscope, the cross-sectional shape of the tube plug is T-shaped, and the tube plug includes a plug body and an end cover, the end cover is arranged on the outer side of the plug body, the above-mentioned connecting piece is fixedly connected to the end cover, the outer diameter size of the plug body is adapted to the inner hole size of the catheter connector, the plug body is inserted into the catheter connector, and the end cover is against the outer side of the catheter connector.

[0014] In the above-mentioned novel non-invasive positive pressure ventilation mask for bronchoscope, the catheter connector is arranged just above the mouth and nose of the face.

[0015] In the above-mentioned novel non-invasive positive pressure ventilation mask for bronchoscope, the catheter joint, tracheal joint and mask body are made of transparent materials.

[0016] In the above-mentioned novel non-invasive positive pressure ventilation mask for bronchoscope, a hanging buckle is provided on the outer side surface of the mask body.

[0017] The utility model has the following beneficial effects:

[0018] 1. Easy to use. After the laryngoscope is taken out, the catheter of the bronchoscope can be passed through the catheter connector from the inner side of the ventilation mask, and then the ventilation mask can be put on. While the bronchial examination and treatment are being carried out, positive pressure assisted ventilation treatment can be carried out through the ventilation mask;

[0019] 2. When performing normal positive pressure assisted ventilation treatment, insert the tube plug into the opening of the catheter connector to block the opening and reduce the leakage of the ventilation mask;

[0020] 3. The pipe plug is fixed on the ventilation mask through a connector. Since the pipe plug is small, it is prevented from being lost or dropped after opening the pipe plug;

[0021] 4. When performing bronchoscopy, when a tracheal tube is used, only one tube connector can be used, and the other tube connector can be blocked with a tube plug; when an esophageal-tracheal combined catheter ETC is used, the esophagus and trachea can be connected through two tube connectors respectively, which has good applicability;

[0022] 5. There are several hooks on the outer side of the mask body. When the ventilation mask is in use, the mask will be temporarily removed and hung on the bed or around the bed through the hooks for easy access. BRIEF DESCRIPTION OF THE DRAWINGS
