Description

Technical Field

[0001] The utility model relates to the technical field of bronchial inspection instruments, in particular to a droplet-proof protective cover for fiberoptic bronchoscopy inspection. Background Art

[0002] Fiberoptic bronchoscope is suitable for observation of lesions in lobes, segments and subsegments of bronchus, biopsy sampling, bacteriology and cytology examination, and can be used for photography, teaching and dynamic recording with TV system. Fiberoptic bronchoscope is equipped with biopsy sampling mechanism, which can help to find early lesions and perform internal surgical operations such as polypectomy. It is a good precision instrument for bronchial and lung disease research and postoperative examination.

[0003] When medical staff perform bronchoscopy on patients, there are two types of anesthesia for patients undergoing bronchoscopy: general anesthesia and local anesthesia. Local anesthesia is generally used, but during bronchoscopy, the endoscope body irritates the patient's airway mucosa, causing reflex coughing and expectoration, which can cause infection to medical staff.

[0004] Chinese patent CN213758140U provides a device for preventing droplet transmission for bronchoscopic diagnosis and treatment under the protection of respiratory infectious diseases, including a mask and a mouth mask, which can block the secretions splashed from the patient's respiratory tract. However, there is no saliva collection device inside the device, which makes it easy for saliva to contaminate the patient's face; at the same time, the bronchoscope hole structure of the device is simple and cannot adapt well to different models of fiberoptic bronchoscopes.

[0005] Chinese patent CN212729746U provides a painless fiberoptic bronchoscopic anesthesia pipeline adjustment device, including a limit mechanism, which adjusts the distance between the limit plates by rotating the limit valve to adapt to different fiberoptic bronchoscopic devices. The device adapts to different fiberoptic bronchoscopic devices and requires manual adjustment of the limit valve, and the device cannot change the entry angle of the fiberoptic bronchoscopic device as needed during use.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The utility model provides a technical solution: a droplet-proof protective cover for fiberoptic bronchoscopy, comprising a fitting frame 1, a face shield 2 embedded in the fitting frame; the face shield 2 is provided with a microscope access tube 3 at a position corresponding to the nostril, and the microscope access tube 3 is provided with a limit mechanism 4. The face shield 2 is provided with an arc-shaped protrusion at the mouth; a groove 11 is provided at the lower part of the fitting frame; a mask body 5 is installed on the groove 11; a liquid-absorbing cotton is connected to the inner surface of the mask body 5; and a plurality of vents 6 are symmetrically provided on the front end surface of the face shield 2 near the edges on both sides. Ears are also provided on both sides of the fitting frame 1, and the two ears are connected by an elastic binding belt 7.

[0025] Specifically, the limiting mechanism includes a sleeve 8 threadedly connected to the access tube 3 and a conical sleeve arranged inside the sleeve. The upper end of the conical sleeve is fixedly connected to the sleeve 8 by bending outward. The conical sleeve and the sleeve 8 are integrally injection molded with hard plastic. The conical sleeve is composed of a plurality of tiles 9. There is a gap between two adjacent tiles 9, so that a single tile 9 is elastic. A flange 10 is extended inward in a circle inside the access tube orifice, and the conical sleeve is inserted into the flange 10. The conical sleeve can adapt to bronchoscope catheters of different diameters. The method of use is: after inserting the bronchoscope into place, tighten the conical sleeve composed of a plurality of tiles 9 to push the conical sleeve forward, and the conical sleeve and the flange 10 form a conical surface match, thereby causing the feeding tile 9 to shrink inward to clamp and fix the bronchoscope catheter.

[0026] Specifically, the mask has a human face shape and includes a fitting frame 1 and a face shield 2. The fitting frame 1 is used to fit closely with the human face to block air circulation; the face shield 2 is transparent in design, which is convenient for medical staff to observe the patient's reaction and also ensures that the patient is comfortable wearing.

[0027] Preferably, the mask body 5 is a disposable mask, and liquid absorbent cotton is connected to the inner surface; the shape of the lower edge of the mask body 5 is adapted to the shape of the lower inner edge of the frame.

[0028] In this embodiment, a microscopic inspection tube 3 and a limiting mechanism 4 are provided at the position corresponding to the nostrils on the face shield, which serve as the entry end of the fiberoptic bronchoscope; the face shield 2 has a protrusion with a considerable space at the position corresponding to the mouth, and is equipped with a mask body 5 and absorbent cotton, so that the droplets sprayed by the patient when coughing are well blocked inside the mask body 5, so as not to splash into the surrounding air, and at the same time absorb the saliva secreted by the patient. After the inspection, only the mask body 5 and the absorbent cotton need to be replaced, which effectively avoids the spread of the disease. The elastic binding belt 7 can fix the mask tightly on the patient's face to prevent the droplets from spreading to the surrounding air.

[0029] In this embodiment, a limiting mechanism 4 is provided in the endoscope passage tube 3, so as to facilitate the passage of bronchoscopes of different diameters into the patient's nostrils through the endoscope passage tube 3 and improve the stability during use. When inserting a bronchoscope, in order to adapt to the diameter of the bronchoscope catheter, the cone sleeve supports the bronchoscope catheter during the use of the bronchoscope, thereby improving the stability during use and reducing the sliding of the bronchoscope catheter during use.
