Description

An endoscopic respiratory tract flushing device

Technical field

The present invention relates to a medical device, in particular to a fiberoptic bronchoscope respiratory tract flushing tube and its endoscope and a fiberoptic bronchoscope respiratory tract end cleaning device based on the above content, specifically an endoscopic respiratory tract flushing device.

Background technique

Bronchial endoscopy is generally used for bronchial examination, sputum suction, and cleaning operations. It plays the role of removing sputum plugs and sputum, and cleaning the patient's airway. The common method of suctioning sputum is to first flush with water, and then perform a suction operation. The flushing method is to pour water directly to the front. Flushing and suctioning share the same channel. This traditional fiberoptic bronchoscope respiratory tract cleaning (sputum suction) method has the following clinical pain points: 1) It is difficult to quickly clean or aspirate thick or dry sputum adhered to the bronchial mucosa, which seriously affects the ventilation function and even endangers the patient. life; 2) Its product structure and operating performance are not enough to remove inflammatory secretions or foreign matter from the respiratory tract terminals; 3) The product design of traditional fiberoptic bronchoscope can only use the working mode of flushing and then suctioning, and cannot quickly clear the respiratory tract. , it takes a long time and significantly increases the risk of operation; 4) During operation, flush first and then suction. The same lumen is used for flushing and suction, which can easily cause contamination of the sputum suction pipe and may cause suffocation and other safety hazards to the patient. Therefore, it is difficult for existing products to completely and quickly clean adherent sputum and deep peripheral bronchial sputum. The operation is risky, relatively time-consuming and labor-intensive. Therefore, there is an urgent clinical need to innovate and design a device that can quickly and effectively wash and clean the respiratory mucosa and suction sputum, and can clear respiratory terminal secretions through rapid siphoning. For this reason, Chinese patent ZL202120352400.4 has better solved such problems. The applicant found that the irrigation tube and suction tube used in the patent are both fixed in the endoscopic surgical channel, and it uses the outer tube of the endoscope as the infusion channel. During the spraying process, flushing can only be carried out at the same time, and spray flushing cannot be carried out at a fixed point or direction for fine peripheral bronchi. It is inconvenient to use, and at the same time, it cannot realize off-peak flushing and cleaning of thick sputum, so as to achieve the precise positioning and flushing effect of fine peripheral bronchial tubes. At the same time, the problem of increased operation time must be solved.

Contents of the invention

The purpose of the present invention is to design an endoscopic respiratory tract flushing device in view of the problems that existing fiberoptic bronchoscopes (i.e. endoscopes) have limited flushing range and the flushing tube cannot flush fine peripheral bronchial sputum at fixed points and directions.

The invention adopts an integrated flushing and suctioning style, and a hand-held control bending device. The flushing and suctioning are divided into different lumens, and are flushed through the tube wall at 360°. The water flow diverges and flushes directly towards the tracheal mucosa, which solves the problem of direct flushing into the tracheal mucosa in the past. The problem is that water is injected into the airway but the mucous membrane cannot be pressurized to flush and clean the bronchus. Since flushing and suction are controlled through independent channels, different operating modes can be conveniently and flexibly adopted, such as simultaneous flushing, staggered flushing, siphon flushing, etc., to achieve the purpose of cleaning the respiratory tract efficiently and quickly, and effectively cleaning the respiratory tract endings. Moreover, the operation is time-saving and labor-saving, and there is no secondary contamination of sputum. It can significantly shorten the operation time and reduce the operational risk of cleaning up inflammatory secretions in the respiratory tract during bronchoscopy.

The control host 27 is composed of: a host computer and software (which can be compiled by oneself using existing technology or directly entrusted to write the corresponding software) to control pulse-type and intermittent flushing, and the flushing direction is adjustable. It solves the problem of airway suffocation caused by continuous water injection and cleaning. It is equipped with an endoscopic lens to visually clean the airway. It is equipped with a biopsy hole and can promptly clean patients with phlegm plugs. It is easy for doctors to operate. The bell-mouthed arc-shaped and tapered design of the head makes it easier to clean the small bronchus 360 degrees, and the water flow is sprayed in an annular and diagonal shape.

Directional flushing, peak-shifting flushing - Two holes and single holes can be opened separately for peak-steering flushing, diverting flushing and cleaning the bronchial wall sputum more thoroughly.

Fixed-point irrigation: It is not necessary to open the entire lumen. It can be used to flush the delicate bronchial terminals at fixed points without opening the entire lumen. It can protect the mucosa of the terminal bronchi.

The invention has a simple structure, is safe, stable and reliable. The invention realizes the precise, fast and directional flushing characteristics of the flushing tube. The main body of the endoscope can be used repeatedly after routine disinfection. At the same time, it realizes the multi-purpose of the scope, which can be used for both routine inspection and It is used to clean the lungs, quickly save the lives of patients with emphysema or lung obstruction, and keep breathing smooth.

The present invention can also control the time of water injection and suction to cause the water rushing into the pulmonary alveoli to lose pressure instantly and quickly enter the suction tube, thereby cleaning the mucus in the pulmonary alveoli and saving the lives of patients with severe pneumonia. Solve the current problem of being unable to effectively clean lung air bubble mucus.
