Description

Technical Field

[0001] This utility model relates to a tracheostomy tube sealing cap, belonging to the field of medical device technology. Background Technology

[0002] After a tracheostomized patient's condition stabilizes to a certain extent, the endotracheal cannula, which has been gradually replaced with a metal one, needs to be removed and sealed to restore normal airway access through the nose and mouth. Currently, sealing is mostly done by direct closure. Before sealing, family members often improvise with whatever materials are available, such as syringe needle caps, cut-off tips from suction catheters, or homemade plugs made from cotton balls and gauze. There are no standardized or dedicated materials available. Most of the temporary substitutes are inserted into the inner wall of the cannula for fixation and are not disposable, which can easily lead to contamination and infection, and makes it difficult to control and quantify ventilation.

[0003] Currently, there are other types of sealing devices on the market, but they all have problems such as complex structure, large weight and size, high cost, and inconvenience of use.

[0004] Therefore, there is an urgent need to design a tracheostomy tube sealing cap that can solve the above-mentioned technical problems. Utility Model Content

[0005] To address the shortcomings of the existing technology, this invention provides a tracheostomy tube sealing cap with a reasonable structural design and a gradual sealing method, aiming to help patients adapt gradually and reduce discomfort and infection risks.

[0006] A tracheostomy tube sealing cap is characterized by comprising a first cap body 1, a second cap body 2, and a third cap body 3. The first cap body 1 and the second cap body 2 are respectively provided with a first air inlet 5 and a second air inlet 6. The diameter of the first air inlet 5 is larger than that of the second air inlet 6. The third cap body 3 is a closed design that can completely seal the tracheostomy tube 4. The above three cap bodies are alternately installed on the tracheostomy tube 4 according to the actual situation to achieve progressive sealing of the tracheostomy tube 4.

[0007] Preferably, the upper surface of the cap body is provided with a plurality of spaced-apart pillars 7, the height of which is 3-5 mm;

[0008] Preferably, the first air inlet 5 is located at the center of the first cap body 1. The first air inlet 5 is composed of a first suction hole 5-1 and a semi-circular through hole 5-2. The diameter of the first suction hole 5-1 is smaller than that of the semi-circular through hole 5-2, and the first suction hole 5-1 and the semi-circular through hole 5-2 partially intersect.

[0009] Preferably, the second air inlet 6 is located at the center of the second cap 2, and the second air inlet 6 is the same size as the first suction hole 5-1;

[0010] Preferably, the cap body is made of medical polyethylene material;

[0011] Preferably, the cap body is snapped onto the end of the tracheal cannula 4, and the snapping point between the cap body and the tracheal cannula 4 is designed as a three-point snap-fit ​​type. Specifically, the cap body is provided with three vertically downward extending snap arms 8, the three snap arms 8 are spaced apart, the side of the snap arm 8 facing the tracheal cannula 4 is provided with a convex structure 8-1, and the bottom of the snap arm 8 is provided with an outwardly extending flap 8-2.

[0012] The tracheostomy tube sealing cap of this utility model has an ingenious design, and its beneficial effects are analyzed as follows:

[0013] 1. The occlusion cap comes in three types, and is selected gradually in three stages. For the initial test occlusion, the first cap with a slightly larger air inlet is used, and the patient's reaction is observed afterward. If there is no discomfort, the second cap is used to further reduce the air intake, forcing the patient to open and restore the nasal and oral airways. After a period of observation confirming that the patient has no hypoxia or discomfort, the third cap, which provides complete occlusion, can be used. The test occlusion continues until the patient adapts, at which point the cannula can be removed for complete occlusion. This invention employs a gradual occlusion process, allowing the patient to gradually adapt to the occlusion process, ensuring safety and controllability.

[0014] 2. Except for the third cap body that achieves complete occlusion, the other two cap bodies have suction holes for easy suctioning and sputum removal.

[0015] 3. The cap has a support post on top, which can support the dustproof gauze. When installing, the thumb can press the top of the post without touching the air inlet of the cap, reducing the chance of contamination and infection and preventing inhalation.

[0016] 4. Simple structure, lightweight and does not increase pressure on the neck and throat.

[0017] 5. The degree of blocking is selectable, controllable, quantifiable, economical and practical.

[0018] 6. It features a three-point snap-on design, making it easy to remove by simply lifting one of the tabs upwards with your fingernail.

[0019] 7. The cap is individually packaged and sterilized for single use, reducing the risk of infection.

[0020] 8. The cap is fixed to the outer periphery of the tracheostomy tube, which can reduce infection and contamination.

[0021] In summary, the tracheostomy cannula occlusion cap of this invention provides a safe and effective occlusion material and method for tracheostomy patients. It helps patients reduce pain, lower the risk of infection, better participate in rehabilitation training and daily life, and alleviate the nursing burden on medical staff and their families, thereby reducing medical and nursing costs.

[0031] The following detailed description of the present invention is provided with reference to the accompanying drawings.

[0032] Example 1

[0033] This embodiment provides a tracheostomy tube sealing cap, see attached figure. Figure 1-9 It includes a first cap 1, a second cap 2, and a third cap 3. The first cap 1 and the second cap 2 are respectively provided with a first air inlet 5 and a second air inlet 6. The diameter of the first air inlet 5 is larger than that of the second air inlet 6. The third cap 3 is a closed design that can completely block the tracheal tube 4. The above three caps are alternately installed on the tracheal tube 4 according to the actual situation to achieve the gradual blocking of the tracheal tube 4.

[0034] In this embodiment, the upper surface of the cap is provided with multiple spaced-apart pillars 7, each pillar 7 being 3-5 mm high. The dustproof covering gauze is supported by the pillars 7. During installation, the top of the pillar 7 is pressed with the thumb to snap the cap onto the port of the tracheal cannula 4, preventing the hand from touching the air inlet of the cap, thus reducing the chance of contamination and infection and preventing inhalation.

[0035] In this embodiment, the first air inlet 5 is located at the center of the first cap 1. The first air inlet 5 consists of a first suction hole 5-1 and a semi-circular through hole 5-2. The diameter of the first suction hole 5-1 is smaller than that of the semi-circular through hole 5-2, and the first suction hole 5-1 and the semi-circular through hole 5-2 partially intersect. The second air inlet 6 is located at the center of the second cap 2, and the second air inlet 6 is the same size as the first suction hole 5-1. The air inlets gradually decrease in size until they are completely blocked, allowing the patient to gradually adapt to the blocking process, which is safe and controllable.

[0036] The cap in this embodiment is made of medical-grade polyethylene material. This allows for controllability and quantification.

[0037] In this embodiment, the cap body is snapped onto the end of the tracheostomy tube 4. The snap-fit ​​design between the cap body and the tracheostomy tube 4 is a three-point snap-fit ​​type. Specifically, the cap body has three vertically downward extending locking arms 8, which are spaced apart. The side of the locking arm 8 facing the tracheostomy tube 4 has a convex structure 8-1, and the bottom of the locking arm 8 has an outwardly extending flap 8-2. With the three-point snap-fit ​​fixation of this embodiment, it can be easily removed by simply lifting one of the flaps 8-2 upwards with a fingernail.

[0038] Sterilized individual packages are for single use, reducing the risk of infection.

[0039] The sealing cap in this embodiment comes in three types, and should be selected progressively in three stages during use:

[0040] 1. Half-blocking test: For the first test block, select half of the first cap 1 and install the first cap 1 on the tracheostomy tube 4. Observe the patient's reaction after use.

[0041] 2. Three-quarters blockage: If there is no discomfort, proceed to the intermediate stage and block three-quarters of the cap, i.e., the second cap 2. Remove the first cap 1 and install the second cap 2 on the tracheostomy tube 4 to further reduce the intake volume and force the patient to use the nasal and oral airways to restore airway.

[0042] 3. Complete occlusion: After observing and confirming that the patient has no hypoxia or discomfort after blocking three-quarters of the orifice for a period of time, the complete occlusion cap can be selected. That is, the second cap 2 is removed and the third cap 3 is installed on the tracheostomy tube 4. After the patient adapts, the primary condition for complete occlusion is met.

[0043] The occlusion cap of this embodiment provides a safe and effective occlusion material and method for tracheotomized patients. It helps patients reduce pain, lower the risk of infection, better participate in rehabilitation training and daily life, and alleviate the care burden on medical staff and their families, thereby reducing medical care costs.
