Description

TECHNICAL FIELD

[0001] The utility model relates to the instrument that will medium input in the human body or to the instrument on the human body, such as trachea with cannula, specifically related to a tracheostomy cannula that can be washed in the process of cannula. BACKGROUND

[0002] Tracheotomy is to cut open the neck section of the trachea and insert a metal trachea cannula or a silicone cannula, which is a common operation to relieve laryngeal respiratory difficulty, respiratory dysfunction or respiratory difficulty caused by retention of lower respiratory tract secretions. There are two problems in the process of this operation. First, the process of inserting the tracheostomy cannula after tracheotomy cannot be visualized. The current tracheostomy cannula can only solve the problem of visualization after insertion, but cannot solve the problem of visualization during insertion. It is very important to realize the visualization of the insertion process, otherwise it is easy to insert the tracheostomy cannula into the soft tissue in front of the neck instead of the trachea, causing trauma to the soft tissue in front of the neck or even subcutaneous emphysema, and aggravating the problem of airway obstruction in patients. The wrong placement of the cannula may even cause suffocation and death in the patient within a few minutes. Second, after the current tracheostomy cannula is inserted, the blood continuously flowing out of the tracheostomy stoma will accumulate in the gap between the trachea and the tracheostomy cannula. Due to the blockage of the tracheostomy cannula cuff, the blood cannot continue to flow to the distal end of the trachea and be sucked out. These accumulated blood in the gap may cause infection, and more importantly, if the tracheostomy cannula needs to be removed, the blood clots may block the trachea after the tracheostomy cannula is removed, causing suffocation and death in the patient within a few minutes. There is currently no tracheostomy cannula that can solve the above two problems during tracheostomy. SUMMARY

[0003] The utility model embodiment provides a tracheostomy cannula that can be visualized and washed during cannulation, which can visualize cannulation and fully wash the blood in the gap between the trachea and the tracheostomy cannula during long-term indwelling.

[0004] According to one aspect of the utility model, a tracheostomy cannula that can be visualized and washed during cannulation is provided, which includes an outer tube and a tube core adapted thereto. The outer tube is provided with an annular air bag on the outside. The annular air bag is connected to an inflation balloon through a thin tube one in the tube wall of the outer tube. The outer tube is also provided with an annular tube one. The annular tube one is uniformly distributed with at least four suction holes one in the circumferential direction and is connected to a washing and suction end one through a thin tube two in the tube wall of the outer tube. A miniature camera one and a cold light source one are attached to the inner wall of the outer tube. A miniature camera two and a cold light source two are provided at the end of the distal end of the tube core. The miniature camera one and the miniature camera two are respectively electrically connected to an OTG interface one and an OTG interface two through wires. The OTG interface one and the OTG interface two are electrically connected to an external display terminal.

[0005] In some embodiments, the outer tube is further provided with a second annular tube adjacent to the annular balloon, the second annular tube is uniformly distributed with at least four suction holes two along the circumference and connected with a second flushing suction end through a third thin tube in the wall of the outer tube.

[0006] In some embodiments, the upper part of the outer tube is provided with a band fixing plate, both ends of the band fixing plate are provided with through holes.

[0007] In some embodiments, the inner diameter of the outer tube is 7.5mm, and the maximum diameter of the tip of the tube core is 7mm.

[0008] In some embodiments, the distance H between the first annular tube and the band fixing plate is 2cm-4cm.

[0009] In some embodiments, the top of the outer tube is provided with a joint for connecting a breathing machine threaded tube.

[0010] In some embodiments, the joint part of the tube core is clamped in the joint.

[0011] Based on the above technical solution, the utility model has at least the following beneficial effects:

[0012] The micro camera one is used for observing the situation in the airway in real time during the tracheal cannula placement process, the process of placing the tracheal cannula after tracheotomy is visualized, the possibility of placing the tracheal cannula in the soft tissue interlayer is avoided, the success rate of cannulation is improved, and the incidence of situations such as endangering the safety of patients due to incorrect cannulation position is reduced. The micro camera two is used for observing the situation in the airway in real time during the whole retention process after the tracheal cannula is placed. Meanwhile, the blood accumulated in the gap between the trachea and the tracheal cannula after tracheotomy can be sucked out from the suction hole one and the suction hole two by the flushing suction end one and the flushing suction end two in time, so that the accumulated blood is effectively and sufficiently removed through repeated flushing and suction, the patient is prevented from being infected, and the formation of blood clots is avoided, thereby greatly reducing the incidence of suffocation and death of patients caused by blood clots blocking the trachea when the tracheal cannula is pulled out.

In the embodiment, the annular tube 1 9 is connected with the flushing and suction end 1 6, and the annular tube 2 1 0 is connected with the flushing and suction end 2 7. The accumulated blood is sucked into the annular tube 1 9 and the annular tube 2 1 0 through the suction holes 1 20 and the suction holes 2 1 respectively, and then is finally sucked out by the flushing and suction end 1 6 and the flushing and suction end 2 7 through the thin tube 2 2 and the thin tube 3 2 3 respectively, so as to repeatedly flush and suck the accumulated blood, avoid infection of the patient, and more importantly, avoid the formation of blood clots, thereby avoiding the obstruction of the airway caused by the blood clots when the tracheostomy tube is pulled out, and thus avoiding the danger to the safety of the patient.

[0021] The inner wall of the outer tube 1 is attached with a micro camera 17, and the end of the tip 13 of the tube core 11 is provided with a micro camera 14, and the micro camera 17 and the micro camera 14 are respectively provided with a cold light source 1 (not shown in the figure) and a cold light source 2 (not shown in the figure), and the micro camera 17 and the micro camera 14 are respectively connected with an OTG interface 18 and an OTG interface 15 through wires, the OTG interface 18 and the OTG interface 15 are respectively connected with an external display terminal commonly used in the art, and the OTG interface 18 and the OTG interface 15 also respectively provide power for the micro camera 17 and the micro camera 14. The above-mentioned micro camera 17, micro camera 14, cold light source 1, cold light source 2, wire, OTG interface 18, OTG interface 15, external display terminal are all mature products, and the specific connection mode is a conventional technical means in the art, which will not be described here. The tracheostomy cannula of the present application is used by sleeving the tube core 11 into the outer tube 1, turning on the external display terminal, ensuring that the two cameras and the power supply work normally and display, and after the trachea is cut, the whole tracheostomy cannula is put into the tracheostomy, and the tracheal cannula is observed by the two cameras during the tracheal cannula placement process and after the tracheal cannula placement process, so that the whole tracheal cannula placement process and the tracheal cannula placement process are carried out under the condition of being observed, and the appearance of the tracheal ring on the external display terminal indicates that the tracheostomy cannula is placed in the trachea, and it is not misdirected into the soft tissue interlayer.
