Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, and in particular relates to a modified silicone spiral tracheostomy tube occlusion device. Background Technology

[0002] Tracheostomy is currently one of the common measures for maintaining airway patency, preventing aspiration and respiratory failure, and saving lives in critically ill emergency patients. Early and successful extubation of tracheostomized patients is crucial to their prognosis. Long-term cannula indwelling or difficult extubation not only increases the risk of pulmonary infection, but may also cause swallowing dysfunction, airway stenosis, tracheoesophageal fistula, cannula blockage by sputum crusts, tracheomalacia, etc. These complications not only affect the patient's recovery process, but also increase the difficulty of clinical nursing and medical burden. Therefore, scientific assessment and selection of the appropriate extubation time are very important for the patient's prognosis and to avoid re-intubation. The series of operations from plastic cannula to metal cannula, to occlusion and extubation are crucial to the patient's recovery and prognosis. The occlusion test performed on tracheostomized patients before extubation is crucial to the success rate of extubation. The occlusion test is mainly used for patients who have changed from plastic cannula to metal cannula.

[0003] Currently, there is no unified or standardized procedure in clinical practice for the use of specialized equipment for endotracheal tube occlusion before extubation in tracheostomized patients. Medical staff need to prepare before removing the endotracheal cannula, primarily by observing the patient's blood oxygen saturation, respiratory rate, and ability to cough up sputum. The procedure typically begins with partial occlusion, progressing to partial occlusion, then partial occlusion, then partial occlusion, and finally complete occlusion. Therefore, clinical practice generally requires nursing staff to conduct occlusion training as needed or on a regular basis, depending on the patient's condition. Medical staff use wooden wedges to occlude the tube and observe the patient's condition before extubation based on clinical experience, but this method has the following drawbacks:

[0004] 1. The endotracheal cannula plugs used in clinical practice are made of wood. They have a long service life and require repeated cleaning, disinfection and soaking treatment, which makes them prone to breakage, increasing the risk of accidents during hospitalization. Due to infection control requirements and aseptic concepts, they need to be replaced frequently over a long period of time, which can easily increase the risk of secondary infection.

[0005] 2. Depending on the material and diameter of the patient's cannula, wooden wedges need to be shaped by family members themselves. If the size is not right, they cannot be used and the depth cannot be adjusted. This can result in the cannula being blocked too deeply or too shallowly, which is difficult to control. Moreover, the appearance is rough and unsightly, which affects the patient's image and increases psychological burden.

[0006] 3. For patients in the rehabilitation department whose condition is stable and who need to have their tracheostomy tubes removed, long-term use of wooden tubes may cause wooden wedges to fall off, resulting in foreign body obstruction and increasing the risk of airway blockage.

[0007] 4. There is no experimental data to support the use of this type of wood-molded material in hospital wards, and it lacks safety and standardization.

[0008] 5. The use of wooden wedges lacks evidence-based medical support and is therefore questionable.

[0009] Based on this, this utility model designs an improved silicone spiral tracheotomy tube plugging device to solve the above problems. Utility Model Content

[0010] The purpose of this invention is to address the problems of existing tracheal occluders requiring repeated cleaning, disinfection, and soaking during use, which can easily lead to breakage and increase the risk of accidents during hospitalization; the need for frequent replacement due to infection control requirements and aseptic concepts, which can easily increase the risk of secondary infection; and the risk of wooden wedges falling off due to long-term use of wooden cannulas, which can cause foreign objects to become lodged and increase the risk of airway obstruction. Therefore, this invention proposes an improved silicone spiral tracheostomy cannula occluder.

[0011] To achieve the above objectives, the present invention adopts the following technical solution:

[0012] An improved silicone spiral tracheostomy tube occlusion device includes an occlusion assembly. The occlusion assembly includes an integrally formed knuckle tube and an occlusion device body. The occlusion device body and the knuckle tube are hollow structures. A spiral anti-dislodgement strip is wound and connected to the inclined surface of the occlusion device body. The occlusion device body, the knuckle tube, and the spiral anti-dislodgement strip are all made of silicone rubber.

[0013] As a further description of the above technical solution:

[0014] The finger tube is fitted with a limiting finger plate, which has an external connection hole. The limiting finger plate is connected to the air duct through the external connection hole to prevent it from falling.

[0015] As a further description of the above technical solution:

[0016] A nameplate is connected to the limiting finger plate, and the nameplate is provided with the diameter scale of the plug body.

[0017] As a further description of the above technical solution:

[0018] The tail end of the knuckle tube is connected to a pressurizing and expanding assembly. The pressurizing and expanding assembly includes a pressurizing connector connected to the tail end of the knuckle tube. The other end of the pressurizing connector is connected to a pressurizing connecting tube. The other end of the pressurizing connecting tube is connected to a connector that is connected to a syringe. A tube clamp is fitted onto the pressurizing connecting tube.

[0019] As a further description of the above technical solution:

[0020] The pressure boosting connector is connected to a pressure relief pipe, and a pressure relief valve is installed on the pressure relief pipe.

[0021] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0022] 1. In this utility model, silicone rubber is a high-performance polymer medical material. It is used as a medical artificial material. It has a low cost, high practicality, is not prone to rejection reactions, does not cause any harm to the human body, and has good biological adaptability. As gas is continuously injected into the occluder body, the gas pressure gradually increases, and the occluder body expands. The expanded occluder body tightly adheres to the inner wall of the trachea, forming a good sealing effect. Moreover, no force is required when inserting the occluder body into the trachea, making it convenient to use.

[0023] 2. In this utility model, silicone rubber products have excellent medical properties. The material is colorless, non-toxic, oxidation-resistant, flexible, acid and alkali resistant, high temperature resistant, free of leachates, oil-resistant, drop-resistant and rust-free, biocompatible, and non-allergenic. It also has excellent wear resistance, soft touch, and moisture resistance. Silicone rubber products can solve difficult medical problems and meet the medical needs of patients.

[0024] 3. The silicone rubber spiral occluder of this utility model is economical and affordable, making it accessible to most families and reducing the financial burden on patients. It can be cleaned, disinfected, and reused repeatedly after soaking, ensuring cleanliness and reducing the risk of infection. Furthermore, it is simple and easy to operate, making it suitable for patients with long-term tracheostomy and rehabilitation patients receiving home care.

[0025] 4. In this utility model, the silicone rubber spiral occluder can be selected according to the patient's condition and the type of cannula. Especially in the pre-extubation preparation stage, the cannula can be gradually blocked. The operation is simple and easy to educate patients on its use. Family members and caregivers can observe blood oxygen saturation and respiratory rate, as well as the patient's comfort, thus reducing the workload of medical staff.

[0026] 5. In this utility model, when the silicone rubber spiral occluder is used to block the tube, observe the possible breathing difficulties and select an occluder of appropriate diameter according to the doctor's advice. This can make the patient's breathing smoother, prevent hypoxia, prevent the accumulation of sputum locally, and ensure proper local cleaning to prevent infection.

[0027] 6. In this utility model, it is fixed tightly to the tracheal cannula, which can avoid the phenomenon of wedge falling off compared to wooden ones, and it will not fall off when turning over.

[0028] 7. In this utility model, the silicone spiral occluder is designed with a tube diameter scale, which can be seen directly from the appearance to see how much tube is blocked, accurately record the patient's tube blockage status, and provide a reliable basis for observing the progress of the condition.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0036] Please see the appendix Figure 1 - Appendix Figure 4 This utility model provides a technical solution: a modified silicone spiral tracheotomy tube occluder, including an occluder assembly 1. The occluder assembly 1 includes an integrally formed knuckle tube 101 and an occluder body 102. The occluder body 102 and the knuckle tube 101 are hollow structures. A spiral anti-dislodgement strip 103 is wound and connected to the inclined surface of the occluder body 102. The occluder body 102, the knuckle tube 101 and the spiral anti-dislodgement strip 103 are all made of silicone rubber.

[0037] Specifically, a limiting finger plate 2 is fitted on the finger tube 101. The limiting finger plate 2 has an external connection hole 3. The limiting finger plate 2 is connected to the air duct through the external connection hole 3 to prevent it from falling.

[0038] Specifically, a nameplate 4 is connected to the limit finger plate 2, and the nameplate 4 is provided with the diameter scale of the plug body 102.

[0039] Specifically, the tail end of the knuckle tube 101 is connected to a pressurizing expansion assembly 5. The pressurizing expansion assembly 5 includes a pressurizing connector 501 connected to the tail end of the knuckle tube 101. The other end of the pressurizing connector 501 is connected to a pressurizing connecting tube 502. The other end of the pressurizing connecting tube 502 is connected to a connector 503 connected to a syringe. A tube clamp 504 is sleeved on the pressurizing connecting tube 502.

[0040] Specifically, a pressure relief pipe 6 is connected to the pressure boosting connector 501, and a pressure relief valve 7 is installed on the pressure relief pipe 6.

[0041] Working principle and usage:

[0042] Medical staff use a knuckle tube 101 to insert the occluder body 102 into the trachea. Then, they use a medical cotton swab soaked in disinfectant alcohol to wipe the connector 503. Next, they insert a syringe into the connector 503, then open the clamp 504 and push the syringe. The gas in the syringe enters the pressurizing connecting tube 502 through the connector 503, and then enters the occluder body 102 and the knuckle tube 101 through the pressurizing connector 501. As gas is continuously injected, the gas pressure in the occluder body 102 gradually increases, and the occluder body 102 expands. The expanded occluder body 102 adheres tightly to the inner wall of the trachea, forming a good occlusion effect. Moreover, no force is required when inserting the occluder body 102 into the trachea, making it convenient to use.

[0043] If the patient experiences discomfort during the process of injecting gas into the occluder body 102, the gas inside the occluder body 102 can be discharged through the pressure relief pipe 6 by operating the pressure relief valve 7.
