Description

TECHNICAL FIELD

[0001] The utility model relates to medical equipment technical field, concretely relates to a kind of switching device for plastic tracheostomy tube and lung function filter. BACKGROUND

[0002] Tracheostomy is widely used in airway obstruction, neuromuscular diseases and patients who need long-term mechanical ventilation. This technique is by cutting the neck section of trachea and putting a tracheostomy tube into it, which effectively relieves respiratory distress and effectively removes the secretions in the lower respiratory tract to keep the airway unobstructed. Plastic tracheostomy tube can provide airtight airway due to its airbag feature, and can be connected to a ventilator, commonly used for patients with early tracheostomy, continuous mechanical ventilation or risk of coughing.

[0003] In the management of tracheostomy patients, lung function test can help the medical team to comprehensively evaluate the respiratory status of the patients, so as to provide more effective treatment and care. Especially for patients with airway involvement (such as airway amyloidosis, recurrent polychondritis, granulomatous polyangiitis, etc.), the use of plastic tracheostomy tube is required in a short period of time after airway intervention. Lung function test can help medical staff to directly understand the recovery of patient's respiratory function and guide the follow-up treatment plan. However, for such patients who cannot perform oral lung function test temporarily, only tracheostomy tube can be used for examination, but the existing lung function respiratory filter device cannot be effectively matched with the plastic tracheostomy tube. The connection between the respiratory filter device and the plastic tracheostomy tube will leak during detection, resulting in errors in test results. If a breathing extension tube is used for switching, the extra resistance will be too high due to the long intermediate pipeline, which will also affect the accuracy of the test results. SUMMARY

[0029] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0030] like Figures 1-4 The device shown is an adapter for a plastic tracheostomy tube and a pulmonary function filter, including a hollow and interconnected first connecting tube 1 and a second connecting tube 2. The diameter of the opening of the second connecting tube 2 is larger than the diameter of the opening of the first connecting tube 1. The first connecting tube 1 is adapted to be connected to the plastic tracheostomy tube 3, and the second connecting tube 2 is adapted to be connected to the respiratory filter 4. Both the first connecting tube 1 and the second connecting tube 2 are made of elastic transparent material.

[0031] The adapter for the plastic tracheostomy tube and the pulmonary function filter connects the plastic tracheostomy tube 3 through the first connecting pipe 1, connects the respiratory filter 4 through the second connecting pipe 2, and realizes the connection between the plastic tracheostomy tube 3 and the respiratory filter 4; the pipe opening diameter of the second connecting pipe 2 is larger than that of the first connecting pipe 1, which facilitates the matching of the existing port of the plastic tracheostomy tube 3 and the respiratory filter 4; the first connecting pipe 1 and the second connecting pipe 2 are made of elastic material, which can tightly connect the first connecting pipe 1, the second connecting pipe 2 and the corresponding pipe opening, realize the perfect adaptation between the plastic tracheostomy tube 3 and the respiratory filter 4 pipeline, ensure the qualified filtering effect under the premise of not affecting the air flow resistance, avoid air leakage at the connection, ensure the accuracy of the determination of the lung function of the tracheostomy patient, and ensure the authenticity and reliability of the test results; meanwhile, the first connecting pipe 1 and the second connecting pipe 2 are made of transparent material, which can more conveniently observe the airway condition of the patient.

[0032] In the embodiment, the first connecting pipe 1 and the second connecting pipe 2 are made of transparent silica gel. In this way, the friction between the first connecting pipe 1 and the plastic tracheostomy tube 3 and the friction between the second connecting pipe 2 and the respiratory filter 4 can be increased, the anti-skid performance can be improved, and the risk of falling after installation can be reduced. Specifically, the first connecting pipe 1 and the second connecting pipe 2 are integrally formed. Specifically, the pipe opening diameter of the first connecting pipe 1 is 15 mm, and the pipe opening diameter of the second connecting pipe 2 is 22 mm. Specifically, the length of the first connecting pipe 1 is 15 mm, and the length of the second connecting pipe 2 is the same as that of the first connecting pipe 1.

[0033] In the embodiment, the first connecting pipe 1 and the second connecting pipe 2 have a mesh structure inside the side wall. In this way, the mesh structure can reduce the weight of the adapter, making it more portable; at the same time, the mesh structure can increase the durability of the first connecting pipe 1 and the second connecting pipe 2, increasing their wear resistance and tear resistance.

[0034] In an alternative embodiment, the thickness of the pipe opening of the first connecting pipe 1 is greater than the thickness of the pipe wall thereof, and the thickness of the pipe opening of the second connecting pipe 2 is greater than the thickness of the pipe wall thereof. In this way, the connection strength between the pipe opening of the first connecting pipe 1 and the plastic tracheostomy tube 3 can be improved, the connection strength between the pipe opening of the second connecting pipe 2 and the respiratory filter 4 can be improved, and the connection stability between the adapter and the plastic tracheostomy tube 3 and the respiratory filter 4 can be further improved.

[0035] In an alternative embodiment, a corrugated hose is communicated between the first connecting pipe 1 and the second connecting pipe 2. In this way, the adapter can be applied between the plastic tracheostomy tube 3 and the respiratory filter 4 which need to be connected in a bent manner.

[0036] Usage: before the lung function test of the tracheostomy patient, replace the plastic tracheostomy tube 3 and inflate the airbag on the plastic tracheostomy tube 3, clamp the nose and close the mouth, so that the tracheostomy patient only breathes from the plastic tracheostomy tube 3. As shown in Figure 4 , when the tracheostomy patient exhales, the exhaled air flows through the plastic tracheostomy tube 3, the first connecting tube 1, the second connecting tube 2, the ventilation pipeline 5, the breathing filter 4, the air outlet pipeline 6, and then enters the lung function instrument. When the tracheostomy patient inhales, the air flow runs in the opposite direction, and the lung function test is performed in this way. The overall air flow process avoids air leakage and ensures the accuracy of the lung function test.

[0037] In summary, the adapter for connecting the plastic tracheostomy tube and the lung function filter connects the plastic tracheostomy tube 3 through the first connecting tube 1 and connects the breathing filter 4 through the second connecting tube 2, realizing the connection between the plastic tracheostomy tube 3 and the breathing filter 4. The port diameter of the second connecting tube 2 is larger than that of the first connecting tube 1, which facilitates the matching of the existing plastic tracheostomy tube 3 and the breathing filter 4. The first connecting tube 1 and the second connecting tube 2 are made of elastic material, which can tightly connect the first connecting tube 1 and the second connecting tube 2 with their corresponding ports, realize the perfect adaptation between the plastic tracheostomy tube 3 and the breathing filter 4, ensure the qualified filtering effect under the premise of not affecting the air flow resistance, avoid air leakage at the connection, ensure the accuracy of the lung function test of the tracheostomy patient, and ensure the authenticity and reliability of the test results. At the same time, the first connecting tube 1 and the second connecting tube 2 are made of transparent material, which can more conveniently observe the airway condition of the patient.

[0038] Obviously, the above embodiments are only examples for clear illustration, and are not limitations of the embodiments. Based on the above description, other different forms of changes or variations can be made by those skilled in the art. Here, it is not necessary and impossible to exhaust all the embodiments. The obvious changes or variations derived therefrom are still within the protection scope of the present application.
