Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a tracheostomy tube with a humidification tubing. Background Technology

[0002] A tracheostomy tube is a medical device inserted into a patient's trachea to replace or assist airway ventilation. It can establish a stable, long-term artificial breathing channel for patients who cannot maintain a patent airway or require long-term mechanical ventilation after tracheostomy. Tracheostomy is a surgical procedure that involves cutting open the anterior wall of the cervical trachea and inserting a tracheostomy tube to create an artificial airway. It is used to relieve acute respiratory distress such as laryngeal obstruction or lower respiratory tract secretion retention, or to maintain the respiratory channel for patients requiring long-term mechanical ventilation. This procedure involves separating the neck tissue and making an incision at the 2nd-4th tracheal rings for tube insertion. A tracheostomy tube is a key auxiliary device for patients requiring prolonged ventilation support after clinical anesthesia, and is also an essential measure to maintain airway patency and ensure respiratory function in critically ill patients with laryngeal obstruction, severe coma, or chronic respiratory failure.

[0003] However, when a tracheostomy tube is inserted, the airflow entering and leaving the lungs is not moistened by the nasal cavity, which often leads to excessively dry air in the trachea. This can cause respiratory secretions inside the trachea or lungs to dry and solidify, blocking the inserted trachea and posing a risk of tracheal function loss.

[0004] Therefore, existing technologies still need to be improved and developed. Summary of the Invention

[0026] In the current technology, special attention needs to be paid to the hydration of the trachea in the monitoring of patients with tracheostomy and intubation. Although the current technology also considers nebulization and humidification, it is often not compatible with the structure of the trachea. This often leads to the air in the trachea being too dry, causing the respiratory secretions in the trachea or lungs to dry and solidify, or even block the inserted trachea, resulting in loss of tracheal function.

[0027] See Figure 1 , Figure 2 and Figure 3 In one embodiment of this invention application, a tracheostomy tube with a humidification tubing 20 is disclosed, comprising a tube body 10 and a humidification tubing 20, wherein an artificial airway 11 is provided on the tube body 10; the humidification tubing 20 is connected to the tube body 10; the humidification tubing 20 is connected to the artificial airway 11 and is used to introduce humidifying liquid into the artificial airway 11.

[0028] The tracheostomy tube with humidification tubing 20 disclosed in this embodiment can inject physiological saline or humidifying water into the artificial airway 11 to form a humidified intubation channel.

[0029] After the intubation tube body 10 enters the trachea, humidifying fluid is continuously or intermittently delivered, allowing the humidifying fluid to enter the artificial airway 11 along the humidification tubing 20. At an appropriate speed, the humidifying fluid flows only along the side wall of the artificial airway 11 without splashing inside the intubation tube body 10, thereby increasing the time that the humidifying fluid adheres to the inner wall of the intubation tube body 10, maintaining a lasting moisturizing effect, keeping the artificial airway 11 moist, preventing secretions from solidifying, preventing damage to the mucosa, and maintaining the normal use of the tracheostomy tube.

[0030] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, in another embodiment of this invention, the cannula body 10 includes a fixing base 12 and a core 13. The fixing base 12 is provided with a main channel 121 and a first side channel 122. The core 13 is nested within the main channel 121. The core 13 is provided with the artificial airway 11 and an inflow channel 131. One end of the inflow channel 131 is connected to the first side channel 122, and the other end is connected to the artificial airway 11. By connecting the humidification tubing 20 through the first side channel 122, the humidification tubing 20 is connected to the gas channel.

[0031] Specifically, the first side channel 122 is inclinedly arranged next to the main channel 121, and the inlet of the first side channel 122 and the main channel 121 are spaced a certain distance apart to facilitate the connection of different components and prevent mutual interference. Specifically, the humidification pipeline 20 includes a connecting pipe 21 and an infusion connector 22. One end of the connecting pipe 21 is inserted into the first side channel 122 and extends to the inlet edge of the inflow channel 131; the other end of the connecting pipe 21 is provided with the infusion connector 22.

[0032] In this embodiment, the connecting tube 21 is inserted into the first side channel 122 to extend directly to the port of the inflow channel 131. Preferably, the outer diameter of the connecting tube 21 is equal to the diameter of the first side channel 122. The side wall of the first side channel 122 contacts the connecting tube 21, generating friction, which can improve the stability of the connecting tube 21 and keep its position stable. The connecting tube 21 extends directly to the inlet edge of the inflow channel 131, so the humidifying liquid can slowly flow out through the connecting tube 21 and flow through the inflow channel 131 to the side wall of the artificial airway 11.

[0033] The humidification operation disclosed in this embodiment can be continuous or intermittent. Therefore, the infusion connector 22 is provided to seal the port of the connecting tube 21 when no humidification liquid is being infused, so as to prevent foreign matter or bacteria from entering the artificial airway 11 and prevent inflammation or complications.

[0034] Specifically, as another embodiment of this invention, the infusion connector 22 is disclosed as a diaphragm-type needleless closed-loop infusion connector 22. The diaphragm-type needleless closed-loop infusion connector 22 is a high-tech, sterile medical connection device installed at the end of an infusion line. Its core function is to achieve a safe and sealed infusion connection without using a needle, thereby significantly reducing the risk of infection and improving operational safety. When connection is needed, simply connect the infusion set interface and open the diaphragm to form a channel for liquid to pass through; moreover, after removal, the elasticity of the membrane will immediately and automatically close it, restoring the sealed state. Therefore, by setting the diaphragm-type needleless closed-loop infusion connector 22, the connecting tube 21 can be opened or closed at any time to facilitate intermittent humidification operations.

[0035] The intubation body 10 disclosed in this embodiment is inserted into the trachea at the tail end and fixed to the larynx at the head end during use. It needs to be stable during use and to minimize damage to the trachea. Therefore, it has high requirements for the adaptability of the structure.

[0036] Preferably, such as Figure 2 As shown, in this embodiment, the core 13 is detachably connected to the fixing base 12; and the head end of the fixing base 12 is provided with a first positioning structure 126, and the outer surface of the core 13 is provided with a second positioning structure 133.

[0037] First, during the use of the tracheostomy tube, it is necessary to ensure accurate alignment between the inflow channel 131 and the first side channel 122. Therefore, a first positioning structure 126 and a second positioning structure 133 are provided. By aligning the first positioning structure 126 and the second positioning structure 133, it can be determined that the angle of the tube core 13 assembly is accurate, thereby improving the assembly precision, reducing misalignment problems caused by minor deviations, and making the liquid flow more smoothly. Specifically, the first positioning structure 126 and the second positioning structure 133 disclosed in this embodiment can be directly formed by means of protrusions, grooves, engravings, etc.

[0038] Secondly, to ensure stability, the fixing base 12 and the core 13 disclosed in this embodiment are generally made of medical-grade plastic, taking into account stability, flexibility, and sterility. Furthermore, by manufacturing the fixing base 12 and the core 13 separately in this embodiment, the structural complexity of the components is reduced, thus lowering production costs.

[0039] It should be noted that this embodiment only illustrates the material types of the core 13 and the fixing seat 12, but the scope of protection of the present invention is not limited to this. Other types of materials, as long as they can achieve the technical effects disclosed in this application, can be used as equivalent substitutions for the concept of the present invention and should also be within the scope of protection of this application.

[0040] Third, after prolonged use, secretions will adhere to the core tube 13. Separating the core tube 13 from the mounting base 12 allows for separate cleaning and maintenance, reducing contamination and extending the service life of the tracheostomy tube.

[0041] Specifically, as another embodiment of this invention, a portion of the fixing seat 12 is protruding and fitted with a sealing ring. The tube core 13 is nested on the protrusion of the fixing seat 12. The sealing ring enhances the airtightness of the connection between the tube core 13 and the fixing seat 12, making the entire artificial airway 11 more complete and reducing the probability of air leakage.

[0042] It should be noted that this embodiment only illustrates the connection method between the core 13 and the fixing seat 12, but the protection scope of the present invention is not limited to this. Other types of connection methods, such as interference fit, snap-fit, etc., as long as they can achieve the technical effect disclosed in this application, can be used as equivalent replacements for the concept of the present invention and should also be within the protection scope of this application.

[0043] like Figure 1 , Figure 2 and Figure 3 As shown, in another embodiment of this invention, the fixing base 12 is provided with a first flat strap 60 and a second flat strap 70 on both sides respectively. The first flat strap 60 is provided with a hook and loop fastener 61, and the second flat strap 70 is provided with a hook and loop fastener 71. The hook and loop fastener 61 is used to engage with the hook and loop fastener 71.

[0044] The first flat band 60 and the second flat band 70 disclosed in this embodiment can be cut from skin-friendly fabric, or made of soft rubber material or synthetic resin. Both the first flat band 60 and the second flat band 70 have soft characteristics. In use, the fixing seat 12 is fixed at the incision position, and the first flat band 60 and the second flat band 70 are wrapped around the neck or head from both sides to achieve at least partial overlap. At this time, the hook side 61 and the loop side 71 of the Velcro come into contact, achieving adhesion and maintaining tension, thus stabilizing the fixing seat 12. Overall, the stability of the tracheostomy tube is achieved. When removing, simply tearing apart the first flat band 60 and the second flat band 70 allows for quick contact and locking, making the operation convenient.

[0045] Specifically, to accommodate different patients, the first flat strap 60 or the second flat strap 70 can be set as an elastic rope, elastic bandage, etc., to ensure that the fixation seat 12 can be pulled.

[0046] Specifically, as another implementation of this embodiment, a single flat strap can be used, with a Velcro strap at each end. The ends of the strap are then inserted into the holes on both sides of the mounting base 12, allowing the mounting base 12 to be secured around the neck or head.

[0047] In summary, this embodiment uses Velcro for fixation, which can maintain tension for a long time, is easy to operate, improves work efficiency, and does not cause too much pressure on the patient.

[0048] Preferably, to further reduce pressure on the patient's neck, the width of the Velcro can be increased to approximately 3-8 cm, which can reduce pressure and further increase the stability of the connection. Preferably, soft padding, such as sponge padding, silicone padding, latex padding, etc., can also be provided on the first flat strap 60 or the second flat strap 70 to further reduce discomfort during wear.

[0049] For example Figure 3 As shown, in another embodiment of this invention, the tracheostomy cannula further includes a fluid delivery structure 80 (the accompanying drawings are only simplified schematic diagrams and do not represent a specific structure or shape). The fluid delivery structure 80 is connected to the humidification tubing 20 and is used to deliver humidified liquid and control the flow rate of the liquid. The fluid delivery structure 80 includes any one of a syringe, an infusion pump, or a disposable intravenous infusion set. The syringe disclosed in this embodiment is a medical syringe, which can be operated manually or by a machine, robotic arm, or robot.

[0050] The syringe pumps disclosed in this embodiment include, but are not limited to, electric syringe pumps, push-type syringe pumps, and programmable syringe pumps. The disposable intravenous infusion set disclosed in this embodiment consists of core components such as an intravenous needle, infusion tubing, and a drug solution filter, used to establish a venous and drug solution channel, and incorporates special functional designs such as automatic stoppage and precision filtration. The delivery structure 80 disclosed in this embodiment has the ability to push humidified liquid, and the pushing force is controllable. By precisely controlling the pushing force, the humidified liquid flows smoothly and continuously into the gas channel.

[0051] In addition, the artificial airway 11 can be cleaned by controlling the flow rate of the humidifying liquid in this embodiment. Specifically, after prolonged use, secretions or impurities may remain in the trachea. In this case, the flow rate of the humidifying liquid can be increased to flush the airway and keep the inside of the intubation tube 10 clear. Furthermore, when the patient's trachea is small, or in other situations requiring slow infusion, the flow rate of the humidifying liquid can be reduced to avoid excessive moisture in the artificial airway 11, thus preventing the risk of choking.

[0052] In actual use, when cleaning with humidifying liquid, more liquid enters the trachea, posing a risk of choking. For example... Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, in another embodiment of this invention, the head end of the fixing base 12 is provided with a first side channel 122, and the tail end of the fixing base 12 is provided with a second side channel 123; furthermore, a negative pressure suction channel 124 is provided on the outside of the fixing base 12, the outlet of the negative pressure suction channel 124 is used to connect to the negative pressure suction device 30 (the accompanying drawings are only simple schematic diagrams and do not represent specific structures or shapes), and the inlet of the negative pressure suction channel 124 is connected to the second side channel 123; the core tube 13 is provided with an outflow channel 132, the inlet of the outflow channel 132 is connected to the artificial airway 11, and the outlet of the outflow channel 132 is connected to the second side channel 123.

[0053] In this embodiment, a negative pressure suction device 30 and a negative pressure suction channel 124 are provided to form a suction port with negative pressure on the inner wall of the intubation body 10. During use or flushing, when the humidifying liquid, secretions, impurities, etc. on the side wall of the artificial airway 11 pass through the inlet of the outflow channel 132, they are sucked into the outflow channel 132, then enter the second side channel 123, and are suctioned out of the patient's body through the negative pressure suction channel 124, thereby reducing the risk of coughing and improving the safety of use.

[0054] like Figure 8 and Figure 9 As shown, in another embodiment of this invention, the outflow channel 132 includes multiple branch segments 1321 communicating with the artificial airway 11 and a confluence section 1322 connecting all the branch segments 1321. The multiple branch segments 1321 are arranged in a ring around the artificial airway 11. The humidification pipeline 20 disclosed in this embodiment is connected to the artificial airway 11 and humidifies the liquid with a small initial velocity. Under the influence of gravity, the humidified liquid flows freely and may flow to any position in the artificial airway 11. Therefore, in order to remove excess liquid, secretions, impurities, etc. as much as possible, multiple branch segments 1321 are arranged in a ring along the radial direction of the artificial airway 11 in this embodiment. The liquid sucked in by the multiple branch segments 1321 converges into the confluence section 1322, enters the negative pressure suction channel 124 through the second side channel 123, and is sucked out by the negative pressure suction device 30, thus taking into account both suction efficiency and suction range.

[0055] Specifically, as another embodiment of this invention, the negative pressure suction device 30 is disclosed as a tool that creates a negative pressure state at its suction head using a certain method, causing substances outside the suction head to be squeezed towards the suction head, thereby achieving a "suction" effect. The negative pressure suction device 30 includes a connecting hose, a pressure regulator, and a collection bottle. The pressure regulator controls the negative pressure within the collection bottle to achieve the purpose of drawing liquid into the collection bottle. Specifically, either a split-type negative pressure suction device or an integrated negative pressure suction device can be used.

[0056] like Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, in another embodiment of this invention, the tracheostomy cannula further includes a balloon 40 and an air supply line 50. The balloon 40 is nested at the tail end of the fixation base 12. The air supply line 50 is located on the outside of the fixation base 12 and connected to the balloon 40 for inflation and deflation of gas. The fixation base 12 is also provided with a subglottic suction channel 125, the inlet of which is located at the front end of the balloon 40. The outlet of the subglottic suction channel 125 is connected to the second side channel 123.

[0057] In this embodiment, after the tracheostomy tube is inserted into the trachea, an external air pump is connected to the air supply line 50 to inflate the balloon 40, causing the balloon 40 to fill the trachea and achieve stability within the trachea. Because the balloon 40 blocks the upper trachea, when secretions (such as phlegm) are produced in the larynx, the secretions tend to accumulate at the front end of the balloon 40, which can easily cause inflammation or laryngeal complications.

[0058] In this embodiment, by setting a subglottic suction channel 125 and connecting it to the second side channel 123, secretions can be aspirated, thereby reducing safety issues associated with intubation. Furthermore, in this embodiment, the negative pressure suction channel 124 simultaneously aspirates liquid from both the inner and outer sides of the intubation body 10, eliminating the need for a separate subglottic suction tube, simplifying the structure, reducing costs, and improving work efficiency.

[0059] For example Figure 7 As shown, in another embodiment of this invention, the inlet of the subglottic suction channel 125 is located between the inlet of the branch segment 1321 and the balloon 40. In this embodiment, when the tracheostomy tube is used, the inlet of the subglottic suction channel 125 is located above the balloon 40, and the inlet of the branch segment 1321 is located above the inlet of the subglottic suction channel 125. Therefore, the fluid in the artificial airway 11 is affected by gravity and has a chance to flow naturally to the outside of the fixation seat 12, leaving the artificial airway 11, thereby reducing the chance of fluid entering the lungs, which helps reduce infection and the risk of coughing. At the same time, because the position of the subglottic suction channel 125 is lower than that of the branch segment 1321, there is no need to worry about sputum or secretions flowing from the subglottic suction channel 125 into the artificial airway 11.

[0060] As another embodiment of this application, a tracheostomy dressing change kit is disclosed, comprising a tracheostomy tube configured with a humidification tubing 20 as described above, tracheostomy gauze, disposable iodine swabs, saline swabs, dry cotton swabs, a tracheostomy dust collar, a kidney dish, a double-headed cleaning brush, and protective face shield gloves. By combining various materials used for dressing changes, it facilitates storage, reduces contamination, and improves asepticity during surgery or dressing changes.

[0061] In summary, this application discloses a tracheostomy tube equipped with a humidification tubing 20, comprising a tube body 10 and a humidification tubing 20, wherein an artificial airway 11 is provided on the tube body 10; the humidification tubing 20 is connected to the tube body 10; the humidification tubing 20 is connected to the artificial airway 11 and is used to introduce humidifying liquid into the artificial airway 11. After the tracheostomy tube equipped with the humidification tubing 20 disclosed in this embodiment enters the trachea, the humidification liquid is continuously or intermittently introduced, allowing the humidification liquid to enter the artificial airway 11 along the humidification tubing 20. This maintains a moist environment within the artificial airway 11, prevents secretions from solidifying, prevents damage to the mucosa, and maintains the normal usability of the tracheostomy tube.

[0062] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0063] It should be noted that this invention uses a tracheostomy tube with a humidification system as an example to introduce the specific structure and working principle of the invention. However, the application of this invention is not limited to tracheostomy tubes with a humidification system, and can also be applied to the production and use of other similar workpieces.

[0064] It should be understood that the present invention is not limited to the precise structure described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. The scope of the invention is limited only by the appended claims.

[0065] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
