Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly relates to an adjustable tracheotomy tube plugging device. Background Art

[0002] It is known that tracheotomy is an important rescue measure for critically ill patients or patients with moderate to severe inhalation injuries to maintain airway patency and improve respiration. Before extubation, tracheotomy patients usually need to try tube plugging. The purpose of trying tube plugging is to observe whether the patient can transition to oral and nasal breathing, can expectorate sputum by themselves, and can be smoothly extubated after the respiration is stable, without chest tightness, shortness of breath and being able to expectorate sputum by themselves. The existing tracheotomy tube plugging methods are as follows:

[0003] First, the rubber glove finger cot tube plugging method - it uses the finger cot part of a sterile rubber glove, cuts it off and covers the head of the tracheotomy catheter, and fixes it with 3M tape;

[0004] Second, the transparent dressing tube plugging method - it uses 3M transparent dressing to cover the tracheotomy catheter opening, and tightly adheres to the catheter root. If partial tube plugging is needed, a few small holes can be punctured at the top with a needle;

[0005] Third, the sterile vacuum tube cap tube plugging method - remove the sterile vacuum tube cap, take out the rubber in the cap, and plug the rubber cap into the tracheotomy catheter. This method has firm fixation, is not easy to fall off, and is also convenient to pull out the cap plug;

[0006] Fourth, the Murphy's dropper tube plugging method - cut the middle 1 / 2 of the Murphy's dropper of the infusion set, and put the Murphy's dropper on the tracheotomy catheter. This method is convenient for obtaining materials, simple to manufacture, has firm fixation, and can also be used for partial tube plugging.

[0007] Fifth, tracheotomy metal catheter tube plugging - use the rubber stopper of a disposable syringe, remove it and cover the concave surface on the outer periphery of the inner catheter opening. If semi-tube plugging is needed, a small hole can be cut in the center of the rubber stopper with a sterile scissors, and the hole diameter is gradually reduced from large to small until complete tube plugging.

[0008] To sum up, the existing tracheotomy tube plugging cannot be adjusted. Since many patients cannot tolerate full closure tube plugging, this cannot be adjusted according to the actual needs of patients, which will greatly affect the use safety and subsequent rehabilitation of patients. According to this situation, it is necessary to make improvements. Summary of the Invention

[0036] To make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the drawings and embodiments. However, it should be understood that the specific embodiments described herein are only used to explain the present invention and do not limit the scope of the present invention. In addition, in the following description, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present invention.

[0037] Example 1: Refer to Figure 1 and Figure 3 , an adjustable tracheotomy plugging device, including a tracheotomy cannula connecting tube 1, an inner core tube 2 is arranged on the tracheotomy cannula connecting tube 1, a screw cap 3 is arranged on the inner core tube 2, and a manual adjustment plugging member 4 for adjusting the air intake amount is arranged on the screw cap 3 and the inner core tube 2. When in use, by adjusting the manual adjustment plugging member 4, the ventilation (inlet and outlet air) of the screw cap 3 can be adjusted, which can not only achieve the traditional full closure and full opening, but also can adjust the ventilation amount according to needs. This is beneficial for many tracheotomy patients to avoid safety problems such as asphyxia and respiratory distress caused by their inability to tolerate full closure plugging, and is also more conducive to the progressive plugging training and rehabilitation of patients, improving the success rate of extubation for tracheotomy patients, having great market value and stronger practicability.

[0038] Example 2: It can be described based on Example 1. As Figure 1 and Figure 3 shown, the manual adjustment plugging member 4 includes an inner semi-circular plate 41 arranged on the end face of the inner core tube 2 and an outer semi-circular plate 42 arranged on the end face of the screw cap 3. A through hole is arranged on the screw cap 3, and the inner core tube 2 and the through hole are in clearance fit, which is beneficial for the relative rotation of the inner core tube 2 and the screw cap 3. When the inner semi-circular plate 41 and the outer semi-circular plate 42 overlap with each other, the screw cap 3 and the inner core tube 2 are in a semi-ventilation state. When the inner core tube 2 and the screw cap 3 are relatively rotated, the inner semi-circular plate 41 and the outer semi-circular plate 42 are combined into a shaping circular plate, and at this time, the shaping circular plate can completely close the ventilation of the inner core tube 2 and the screw cap 3. During the rotation of the inner core tube 2 and the screw cap 3, the overlap degree of the inner semi-circular plate 41 and the outer semi-circular plate 42 causes the change of the ventilation amount of the inner core tube 2 and the screw cap 3. Further explanation, an angle scale line 43 is arranged on the outer surface of the inner semi-circular plate 41. Through the angle scale line 43, the rotation angle can be clearly understood, which is more beneficial for clearly adjusting the ventilation amount. In this embodiment, the angle scale line 43 is 0°, 25°, 50°, 75°, 100°, 125°, 150°, 175° and 180°. When the inner core tube 2 rotates at different angles in the screw cap 3, the overlap degree of the inner semi-circular plate 41 and the outer semi-circular plate 42 is adjusted, so as to realize the multi-angle adjustment of the inlet and outlet air according to needs, which is more beneficial to meet the adjustment requirements of users. What's more, the inner core tube 2 and the inner semi-circular plate 41 are integrally formed, and the screw cap 3 and the outer semi-circular plate 42 are integrally formed. This not only has a simple structure, is convenient for production and manufacturing, reduces the production and manufacturing cost, but also the combination of the inner semi-circular plate 41 and the outer semi-circular plate 42 into a shaping circular plate is more beneficial for achieving full closure.

[0039] Among them, the outer wall of the inner core tube 2 is provided with an external thread, and the corresponding through hole on the screw cap 3 is provided with an internal thread. The internal thread and the external thread cooperate with each other to facilitate the disassembly and installation of the inner core tube 2 and the screw cap 3. This is not easy to fall off and is relatively easy to fix.

[0040] The present invention can adjust the air intake volume only by relative rotation of the inner core tube 2 and the screw cap 3, which is beneficial to solve the problem that the existing tube blocking device requires manual selection of air intake holes with appropriate apertures according to the patient's tolerance level, requires repeated assembly, and is inconvenient to operate. In addition, repeated assembly has the risk of leakage and contamination, and may easily damage the lower jaw, which is not conducive to patient use.

[0041] Among them Figure 4 As shown, the screw cap 3 is provided with a flange 31 for folding outwards. This arrangement makes it easier to connect with the outside and more stable, and helps to improve the overall novelty.

[0042] Embodiment 3: It can be described on the basis of Embodiment 1 or Embodiment 2, such as Figure 4 and Figure 5 As shown, the tracheotomy sleeve connecting tube 1 includes a nut 11 sleeved in the end face of the inner core tube 2, and the nut 11 and the inner core tube 2 are interference fit, which improves the firmness and tightness of the connection, and a spiral body 12 is provided on the nut 11, and an outer sleeve 13 is provided on the spiral body 12. The nut 11, the spiral body 12 and the outer sleeve 13 are integrally formed, and the outer sleeve 13 and the inner core tube 2 are connected through the nut 11. This structure is simple, easy to manufacture, and also conducive to the user holding the spiral body 12 to rotate, and this spiral body 12 is conducive to making the inner core tube 2 and the nut 11 more tightly connected and sealed. Further explanation, the nut 11, the spiral body 12 and the outer sleeve 13 are made of medical stainless steel, which greatly improves the safety of use. Further explanation, the inner core tube 2 is made of elastic silicone material, which is easy to manufacture and also allows better connection to the nut 11.

[0043] It should be noted that, although the above embodiments have been described in this article, the scope of patent protection of the present invention is not limited thereby. Therefore, based on the innovative concept of the present invention, changes and modifications made to the embodiments described herein, or equivalent structures or equivalent process changes made using the contents of the present specification and drawings, directly or indirectly applying the above technical solutions to other related technical fields are all included in the scope of protection of the patent of the present invention.
