Description

Technical Field

[0001] This utility model relates to the field of respiratory equipment technology, and in particular to an adjustable respiratory resistance tracheostomy cannula sealer. Background Technology

[0002] Currently, patients with respiratory failure frequently use ventilators, and some require tracheotomy to connect to a ventilator, which is then disconnected once their condition improves. When spontaneous breathing resumes, respiratory function needs to be gradually trained before the tracheostomy tube can be closed to transition to spontaneous breathing mode.

[0003] For example, Chinese utility model patent CN217287105U, with an authorization announcement date of August 26, 2022, discloses a respiratory trainer suitable for tracheotomy patients. The trainer includes a main body with a tubing interface, an expiratory assembly, and an inspiratory assembly. One end of the tubing interface connects to the inspiratory assembly, while the other end connects to a threaded hose, a T-tube, a bacterial filter, and a straight connector, and connects to the expiratory assembly at the top. The inspiratory assembly contains an inspiratory resistance adjustment device. The tracheostomy tube is connected to the bacterial filter via the straight connector. The bottom plate of the inspiratory assembly has four circular perforated holes of varying diameters, evenly distributed along a semicircle. The inspiratory resistance adjustment device is installed below the bottom plate.

[0004] Tracheostomy patients can perform breathing training using the breathing trainer itself. They can manually rotate the handle to adjust the inspiratory resistance, selecting an appropriate opening to adjust the resistance. However, existing breathing trainers are large and complex, making them difficult to connect flexibly to the tracheostomy tube. Dust and dryness in the inhaled air can easily irritate the trachea and cause respiratory discomfort. Utility Model Content

[0005] The technical problem this invention aims to solve is that existing breathing trainers are large and complex in structure, making them difficult to connect flexibly to the tracheostomy tube. The dust and dryness of the inhaled air can easily irritate the trachea and cause respiratory discomfort.

[0006] To solve the above-mentioned technical problems, this utility model provides a technical solution for an adjustable breathing resistance tracheostomy cannula sealer:

[0007] The adjustable breathing resistance tracheostomy tube sealer includes a sealer housing, an inhalation adjustment structure, and a gas filter assembly. One end of the sealer housing is provided with an inhalation port, and the other end of the sealer housing is provided with a connection port.

[0008] The air intake adjustment structure is installed at the air intake port. The air intake adjustment structure includes a fan-shaped sealing membrane and a fan-shaped breathable membrane. The fan-shaped sealing membrane and the fan-shaped breathable membrane are connected to form a sealing membrane. The fan-shaped sealing membrane and the fan-shaped breathable membrane are used to unfold or fold along the circumferential direction to adjust the air intake resistance.

[0009] The sealing device housing has a side interface on its side wall for connecting to a ventilator. The gas filter assembly is installed inside the sealing device housing and is located between the side interface and the connection port. The gas filter assembly has a filter layer and a humidification layer.

[0010] Furthermore, the air inlet is circular in shape, and the air intake adjustment structure includes a circular outer frame, which is fixedly connected to the air inlet. The fan-shaped sealing membrane and the fan-shaped breathable membrane are respectively installed inside the circular outer frame.

[0011] Furthermore, the air intake adjustment structure also includes a fixed shaft and a rotating shaft. The fixed shaft is arranged in the radial direction of the circular outer frame and has a central end corresponding to the center of the air intake port. The rotating shaft is slidably installed on the inner side of the air intake port and rotatably connected to the central end.

[0012] Furthermore, one straight edge of the fan-shaped sealing film is connected to the fixed shaft, the other straight edge of the fan-shaped sealing film is connected to the rotating shaft, and the arc edge of the fan-shaped sealing film is sealed to the circular outer frame.

[0013] Furthermore, one straight edge of the fan-shaped breathable membrane is connected to the fixed shaft, the other straight edge of the fan-shaped breathable membrane is connected to the rotating shaft, and the arc edge of the fan-shaped breathable membrane is sealed to the circular outer frame.

[0014] Furthermore, the fan-shaped sealing membrane is a flexible plastic membrane, and the fan-shaped breathable membrane is a microporous breathable membrane.

[0015] Furthermore, it also includes an air-oxygen mixer, which is provided with an oxygen interface, an air interface and a mixing interface. The oxygen interface and the air interface are arranged on the air inlet side of the air-oxygen mixer, and the mixing interface is arranged on the air outlet side of the air-oxygen mixer. The mixing interface is connected to the side interface.

[0016] Furthermore, the outer side of the connection port is provided with a buckle or external thread section, which is used for detachable connection with the tracheotomy sleeve.

[0017] Compared with the prior art, the adjustable breathing resistance tracheostomy tube sealing device of this utility model has the following advantages: The adjustable breathing resistance tracheostomy tube sealing device adopts a design of sealing device shell, inhalation adjustment structure and gas filter assembly. One end of the sealing device shell is provided with an inhalation port, and the other end of the sealing device shell is provided with a connection port. The inhalation adjustment structure is installed at the inhalation port. The inhalation adjustment structure includes a connected fan-shaped sealing membrane and a fan-shaped breathable membrane. The fan-shaped sealing membrane and the fan-shaped breathable membrane form a sealing membrane that is partially sealed and partially breathable. The entire sealing device is compact and simple in structure. The sealing device can be flexibly connected to the tracheostomy tube through the connection port.

[0018] Both the fan-shaped sealing membrane and the fan-shaped breathable membrane can be unfolded or folded along the circumference. Unfolding the fan-shaped sealing membrane while folding the fan-shaped breathable membrane allows for sealing the inhalation port; conversely, folding the fan-shaped sealing membrane while unfolding the fan-shaped breathable membrane allows for ventilation. This two-part fan-shaped membrane structure, with its separate sealing and breathable functions, meets the need for flexible adjustment of breathing resistance.

[0019] In addition, the sealing device housing has a side interface on its side wall. The gas filter assembly is installed inside the sealing device housing and located between the side interface and the connection port. The gas filter assembly has a filter element layer and a humidification layer. The ventilator can be connected to the side interface of the sealing device housing. The oxygen from the ventilator and the air intake from the inhalation port are filtered by the filter element layer to remove dust, and the humidification layer increases the humidity of the mixed gas, preventing irritation of the trachea due to dust in the inhaled air and dry gas, thus ensuring the patient's breathing comfort.

The fan-shaped sealing membrane 21 and the fan-shaped breathable membrane 22 are connected to form a sealing membrane.

[0029] The fan-shaped sealing membrane 21 and the fan-shaped breathable membrane 22 are used to unfold or fold along the circumferential direction to adjust the resistance of inhalation; the side wall of the sealing device housing 1 is provided with a side interface 13, which is used to connect to the ventilator; the gas filter assembly 3 is installed inside the sealing device housing 1, and the gas filter assembly 3 is located between the side interface 13 and the connection port 12; the gas filter assembly 3 has a filter element layer 31 and a humidifying layer 32.

[0030] This adjustable breathing resistance tracheostomy tube sealing device adopts a design of sealing device housing 1, inhalation adjustment structure 2, and gas filter assembly 3. One end of the sealing device housing 1 is provided with an inhalation port 11, and the other end of the sealing device housing 1 is provided with a connection port 12. The inhalation adjustment structure 2 is installed at the inhalation port 11. The inhalation adjustment structure 2 includes a connected fan-shaped sealing membrane 21 and a fan-shaped breathable membrane 22. The fan-shaped sealing membrane 21 and the fan-shaped breathable membrane 22 form a sealing membrane that is partially sealed and partially breathable. The entire sealing device is compact and simple in structure. The sealing device can be flexibly connected to the tracheostomy tube through the connection port 12.

[0031] Both the fan-shaped sealing membrane 21 and the fan-shaped breathable membrane 22 can be unfolded or folded along the circumference. While unfolding the fan-shaped sealing membrane 21, the fan-shaped breathable membrane 22 can be folded, allowing the inhalation port 11 to be sealed off. Conversely, while folding the fan-shaped sealing membrane 21, the fan-shaped breathable membrane 22 can be unfolded, allowing the inhalation port 11 to be open and breathable. This two-part fan-shaped membrane structure, with its separate sealing and breathable functions, meets the need for flexible adjustment of breathing resistance.

[0032] In addition, a side interface 13 is provided on the side wall of the sealing device housing 1. The gas filter assembly 3 is installed inside the sealing device housing 1 and located between the side interface 13 and the connection port 12. The gas filter assembly 3 has a filter element layer 31 and a humidification layer 32. The ventilator can be connected to the side interface 13 of the sealing device housing 1. The oxygen from the ventilator and the air intake from the inhalation port 11 are filtered by the filter element layer 31 to remove dust, and the humidification layer 32 increases the humidity of the mixed gas, preventing irritation of the trachea due to dust in the inhaled air and dry gas, thus ensuring the patient's breathing comfort.

[0033] In this embodiment, the air intake 11 is circular in shape, and the air intake adjustment structure 2 includes a circular outer frame 23, which is fixedly installed at the air intake 11. The fan-shaped sealing membrane 21 and the fan-shaped breathable membrane 22 are respectively disposed inside the circular outer frame 23. The outer contours of both the air intake 11 and the air intake adjustment structure 2 are designed to be circular, ensuring the matching degree of the shape between the air intake adjustment structure 2 and the air intake 11, and facilitating the unfolding and folding adjustment of the fan-shaped sealing membrane 21 and the fan-shaped breathable membrane 22 along the circumferential direction.

[0034] As a further preferred embodiment, the inhalation adjustment structure 2 also includes a fixed shaft 24 and a rotating shaft 25. The fixed shaft 24 is located in the radial direction of the circular outer frame 23 and has a central end corresponding to the center of the inhalation port 11. The rotating shaft 25 is slidably mounted on the inner side of the inhalation port 11 and rotatably connected to the central end. One straight edge of the fan-shaped sealing membrane 21 is connected to the fixed shaft 24, and the other straight edge of the fan-shaped sealing membrane 21 is connected to the rotating shaft 25. The arc edge of the fan-shaped sealing membrane 21 is in a sealing fit with the circular outer frame 23. Correspondingly, one straight edge of the fan-shaped breathable membrane 22 is connected to the fixed shaft 24, and the other straight edge of the fan-shaped breathable membrane 22 is connected to the rotating shaft 25.

[0035] The fixed shaft 24 fixes one straight edge of the sector-shaped sealing membrane 21 and one straight edge of the sector-shaped breathable membrane 22. Rotating the rotating shaft 25 around the center of the fixed shaft 24 causes the other straight edges of the sector-shaped sealing membrane 21 and the sector-shaped breathable membrane 22 to rotate synchronously, achieving the simultaneous unfolding / folding of the sector-shaped sealing membrane 21 and the sector-shaped breathable membrane 22. Furthermore, the arc-shaped edge of the sector-shaped sealing membrane 21 and the arc-shaped edge of the sector-shaped breathable membrane 22 are sealed together, ensuring smooth movement of the membrane edges and improving the airtightness of the sealing membrane edges.

[0036] In this embodiment, the adjustable breathing resistance tracheostomy cannula sealer also includes an air-oxygen mixer 4.
