Description
Technical Field
[0001] The utility model belongs to the technical field of medical devices, and in particular relates to a visible closed sputum suction tube. Background Art
[0002] When treating patients with severe respiratory diseases, hospitals often need to perform visual airway management to evaluate the effectiveness of suction and airway clearance, observe the airway mucosa, and promptly suction out the patient's respiratory secretions to avoid blocking the airway and worsening the condition. At the same time, attention must be paid to the disinfection of medical equipment to avoid nosocomial infections.
[0003] Currently, a closed suction tube is generally used to suck out respiratory secretions, but this method cannot provide visualized airway management, cannot observe the depth of endotracheal intubation, and cannot promptly detect sudden airway emergencies (endotracheal tube slippage, sputum crust formation, tracheospasm, gastric reflux), etc. Although bronchoscopes can perform visualized airway management, the examination is expensive, and the use of bronchoscopes is very irritating to patients and can easily cause damage to the trachea, which is difficult for patients to tolerate. It is not suitable for frequent use on the same patient, and it takes a long time to prepare, is inconvenient to operate, and consumes manpower and material resources. Utility Model Content

[0006] A visual closed sputum suction tube comprises a flushing module, a sputum suction tube, a joint and a camera module, wherein the flushing module is composed of a negative pressure switch, a sterile bag, a first liquid injection port and a second liquid injection port, wherein the first liquid injection port and the second liquid injection port can be used for injecting drugs or washing with clean water; the sputum suction tube passes through the joint and the sterile bag and is connected to the negative pressure switch, the sputum suction tube is wrapped inside the sterile bag and is not in contact with the outside world, thereby avoiding cross infection in the hospital; the end of the joint is connected to the sterile bag, and the side is connected to the first liquid injection port and the second liquid injection port; the camera module is composed of a guide wire and a camera at the end of the guide wire, wherein the guide wire is arranged inside the sputum suction tube, and the camera is pumped to a suitable position of an endotracheal intubation through the sputum suction tube, so as to perform visual and refined airway management on the patient; when the camera is blurred, the sputum suction tube can be pulled out to the end of the joint, the negative pressure switch can be turned on, and physiological saline can be injected from the first liquid injection port or the second liquid injection port, and the physiological saline is sucked out through the sputum suction tube by the negative pressure, and the camera is cleaned at the same time.
[0007] As another preferred embodiment of the present invention, the diameter of the suction tube is larger than the inner diameter of the cavity at the end of the connector, and the suction tube has good sealing properties with the end of the connector when the suction tube is in and out. When cleaning the camera, physiological saline only enters the suction tube and does not enter the sterile bag, thereby avoiding residue inside the sterile bag.
[0008] An interface module is provided at the interface of the camera pipe. The suction end of the suction tube is an inclined suction hole, and a plurality of side holes are provided on the side to increase the suction area in the suction tube that is reduced due to the influence of the guide wire and the camera volume.
[0009] As another preferred embodiment of the present invention, the guide wire is made of high-toughness metal material so that it will not be broken when the suction tube is pulled out.
[0010] As another preferred solution of the utility model, the guide wire is connected to a USB interface with charging and data transmission functions, which can be connected to a computer screen for real-time observation, so that doctors can better perform refined airway management.
[0011] As another preferred solution of the present utility model, the camera is provided with a light source.
[0012] As another preferred embodiment of the present invention, the guide wire and the camera are both covered with a plastic film to prevent respiratory secretions from contaminating the guide wire and the camera.
[0013] Compared with the prior art, the visible closed sputum suction tube provided by the utility model has the following enhancement effects:
[0014] (1) The operation of the utility model is similar to that of a suction tube, which is simple and convenient. The camera inside the suction tube realizes the visual and refined airway management of the patient, and can observe the internal situation of the artificial airway in real time, timely discover and prevent airway problems, and assist in percutaneous tracheotomy. When the camera is blurred, the flushing module can also be used to clean the camera.
[0015] (2) Compared with traditional bronchoscopes, the present invention has fewer contraindications, causes less damage to the airway, and is easier for patients to tolerate.
[0016] (3) The suction tube and camera of the utility model are wrapped in a sterile bag, thereby avoiding cross infection within the hospital. BRIEF DESCRIPTION OF THE DRAWINGS
