Description

Technical Field

[0001] This invention relates to the field of medical device cleaning and disinfection technology, and in particular to a tracheal cannula cleaning and disinfection device. Background Technology

[0002] Tracheostomy is a crucial medical procedure for rescuing critically ill patients and maintaining airway patency, requiring the insertion of a tracheostomy tube post-operatively. The tracheostomy tube consists of an outer cannula, an inner cannula placed inside the outer cannula, and a core within the inner cannula. The outer and inner cannulas are similar in shape, both being approximately a quarter-circle arc. Placed within the trachea, the tracheostomy tube connects to the respiratory tract and is prone to accumulating large amounts of secretions. To prevent respiratory diseases, regular cleaning, disinfection, and replacement of the tracheostomy tube are necessary. Currently, medical institutions primarily rely on traditional manual cleaning and disinfection methods for handling tracheostomy tubes. The procedure typically involves: initially rinsing the used tube, followed by manual scrubbing by medical staff using cotton swabs, brushes, and tubing brushes to repeatedly clean the inner and outer walls and lumen of the tube to remove adhering sputum, secretions, and other contaminants. Due to the specific arc-shaped structure of the tracheostomy tube, especially the inner wall and lumen, it is very easy for viscous sputum and biofilm to adhere. Manual cleaning is not only time-consuming and laborious, but also difficult to ensure that every tiny corner is thoroughly cleaned. CN202411321329.8 discloses a rotary tracheostomy tube cleaner, which improves the efficiency of cleaning and disinfecting the tracheostomy tube to a certain extent. However, the cleaning roller used for automatic cleaning still adopts a straight roller structure, which is difficult to adapt to the arc-shaped inner wall structure of the tracheostomy tube, resulting in cleaning dead corners during the cleaning process. Therefore, a tracheostomy tube cleaning and disinfection device has been developed. Summary of the Invention

[0009] Furthermore, a sludge tank is provided on the upper part of the workbench below the spindle, and a rinsing frame is fixedly installed on the outside of the sludge tank. A drain pipe is provided at the bottom of the sludge tank and connected thereto. A rinsing nozzle is detachably mounted on the rinsing frame. The rinsing nozzle is connected to an external water source through a rinsing water supply pipe, which is a retractable corrugated pipe structure.

[0010] Furthermore, a horizontal first limiting plate is fixedly installed below the lower positioning roller on the upright plate. A vertical support rod is slidably installed on the first limiting plate. A limiting head is fixedly installed at the lower end of the support rod. A U-shaped mounting seat is fixedly installed at the upper end of the support rod.

[0011] Furthermore, the drive motor is specifically configured as a servo motor, and two contact switches are symmetrically fixedly arranged on both sides of the drive gear on the upright plate. Two contact rods adapted to the two contact switches are symmetrically fixedly arranged on the outer side of the sector gear near both ends. A controller is also fixedly arranged on the upright plate, and the drive motor and the two contact switches are electrically connected to the controller.

[0012] Furthermore, each of the clamping drive mechanisms includes two mounting plates disposed opposite to each other on the back side of the upright plate.

The invention employs an arc-shaped brush rod structure that matches the shape of the tracheal cannula and reciprocates under the drive motor, ensuring that the bristles can reach every corner of the cannula's inner wall, especially the curved sections, fundamentally solving the problem of cleaning dead zones. Furthermore, this invention achieves a synergistic effect of "mechanical brushing + fluid rinsing." The physical friction of the brush removes firmly adhered phlegm and biofilm, while the cleaning fluid is directly and continuously sprayed from the outlet holes on the brush rod through the supply pipe to the brushing points. This "brush-and-rinse" mode immediately washes away the brushed-off dirt, preventing secondary adhesion and greatly improving the efficiency and cleanliness of tracheal cannula cleaning.

Detailed Implementation

[0019] like Figures 1-9 As shown, a tracheostomy tube cleaning and disinfection device includes a workbench 1, on which a cleaning device and a disinfection device are provided.

[0020] The cleaning device includes a vertical plate 2 fixedly mounted on one upper end of the workbench. A horizontal main shaft 3 is rotatably mounted on the lower part of the vertical plate 2. A radial connecting rod 6 is fixedly mounted on the outer peripheral wall of the main shaft 3 along its radial direction. A drive mechanism for driving the radial connecting rod to reciprocate is fixedly mounted on the vertical plate. In this embodiment, the drive mechanism includes a drive motor 4 fixedly mounted on the upper part of the vertical plate 2. A drive gear 5 is mounted on the drive shaft of the drive motor 4. The main shaft and the drive gear are located on the same side of the vertical plate. The end of the radial connecting rod 6 away from the main shaft 3 is fixedly connected to the bottom end of a sector gear 7. The axis of the sector gear 7 coincides with the axis of the main shaft 3. The upper part of the sector gear 7 meshes with the drive gear 5. When the drive motor 4 drives the drive gear 5 to rotate, the radial connecting rod 6 rotates around the main shaft 3 through the meshing transmission relationship between the drive gear 5 and the sector gear 7.

[0021] An arc-shaped brush rod 8 is fixedly installed at the middle of the radial connecting rod 6, and the axis of the arc-shaped brush rod 8 coincides with the axis of the main shaft 3. Multiple brushes 9 are fixedly installed on the arc-shaped brush rod 8.

[0022] In this embodiment, a connecting sleeve 10 is fixedly provided at one end of the radial connecting rod 6 near the main shaft 3. The connecting sleeve 10 is fitted onto the outer peripheral wall of the main shaft 3 and fixedly connected to the main shaft 3 by a fixing bolt 11. With the above arrangement, the fixing bolt 11 can be removed to maintain or replace the arc-shaped brush rod 8 and the brush 9 on the radial connecting rod 6.

[0023] Two upper positioning rollers 12 are symmetrically rotatably mounted above the radial connecting rod 6 on the upright plate 2, and a lower positioning roller 13 is rotatably mounted in the middle below the radial connecting rod 6 on the upright plate 2. Specifically, a horizontal first limiting plate 14 is fixedly arranged below the lower positioning roller 13 on the upright plate 2. A vertical support rod 15 is slidably mounted on the first limiting plate 14. The support rod 15 is slidably engaged with a through hole opened on the first limiting plate 14. A limiting head 16 is fixedly arranged at the lower end of the support rod 15. The diameter of the limiting head 16 is larger than the inner diameter of the through hole on the first limiting plate 14. A U-shaped mounting base 17 is fixedly connected to the upper end of the support rod 15, and a first spring 18 is fitted on the support rod 15 at the position between the mounting base 17 and the first limiting plate 14. The lower positioning roller 13 is rotatably mounted on the mounting base 17.

[0024] like Figure 5 As shown, when installing the tracheal sleeve 19 to be cleaned, the present invention sleeves the tracheal sleeve 19 over the outside of the arc-shaped brush rod 8 and the brush 9. The tracheal sleeve 19 is initially positioned by two upper positioning rollers 12 and the lower positioning roller 13. Under the action of the slidable support rod 15, the lower positioning roller 13 installed on the mounting base 17 can automatically adjust its position in the vertical direction, which is more conducive to the installation of the tracheal sleeve 19 on the arc-shaped brush rod 8.

[0025] The upright plate 2 has two clamping blocks 20 slidably mounted on each other between the two upper positioning rollers 12 and the lower positioning rollers 13, and the back side of the upright plate 2 is provided with two sets of clamping drive mechanisms for driving the two opposing clamping blocks 20 to slide towards or away from each other.

[0026] In this example, each clamping drive mechanism includes two mounting plates 21 oppositely disposed on the back side of the upright plate 2. A bidirectional screw 22 is rotatably mounted between the two mounting plates 21. The bidirectional screw 22 is arranged in the radial direction of the main shaft 3 and the external threads at its two ends rotate in opposite directions. A clamping motor 23 for driving the bidirectional screw 22 to rotate is fixedly mounted on the outer side of one of the mounting plates 21. Two threaded sleeves 24 are respectively threaded to the two ends of the bidirectional screw 22. The outer peripheral walls of the two threaded sleeves 24 near the upright plate 2 are respectively fixedly connected to one end of two sliding connecting rods 25. The middle parts of the two sliding connecting rods 25 are respectively slidably engaged with limiting grooves 26 formed on the upright plate 2. The limiting grooves 26 are arranged in the radial direction of the main shaft 3. The other ends of the two sliding connecting rods 25 are respectively fixedly connected to two opposing clamping blocks 20.

[0027] After the air tube sleeve 19, which is fitted outside the arc-shaped brush rod 8, is initially positioned by the two upper positioning rollers 12 and the lower positioning rollers 13, the two clamping motors 23 are started to drive the corresponding bidirectional screws 22 to rotate. During the rotation of the bidirectional screws 22, the threaded sleeves 24 installed at both ends of the screws move towards each other, thereby driving the two clamping blocks 20 to move relative to each other through the sliding connecting rod 25, thus clamping the air tube sleeve 19 together. In addition, V-shaped grooves 27 are respectively opened on the opposite sides of the two opposing clamping blocks 20. The setting of the V-shaped grooves 27 can improve the clamping stability of the air tube sleeve 19 by the two clamping blocks 20.

[0028] In this embodiment, the drive motor 4 is specifically configured as a servo motor. Two contact switches 28 are symmetrically fixedly mounted on both outer ends of the drive gear 5 on the upright plate 2. Two contact rods 29, each adapted to one of the two contact switches 28, are symmetrically fixedly mounted on the outer side of the sector gear 7 near both ends. A controller (not shown in the figure) is also fixedly mounted on the upright plate 2. The drive motor 4 and the two contact switches 28 are electrically connected to the controller. After the drive motor 4 starts, it drives the sector gear 7 to rotate via the drive gear 5. When one contact rod 29 of the sector gear 7 contacts the corresponding contact switch 28, the contact switch 28 sends a sensing signal to the controller. The controller sends a control command to cause the drive motor 4 to rotate the sector gear 7 in the opposite direction until the other contact rod 29 contacts the contact switch 28. Then, the controller controls the drive motor 4 to adjust its direction again. This rotation, through the forward and reverse switching of the drive motor 4, causes the sector gear 7 to drive the radial connecting rod 6 and the arc-shaped brush rod 8 to reciprocate.

[0029] The arc-shaped brush rod 8 has a liquid-filled cavity 30 inside, and multiple sets of liquid outlet holes 31 are evenly opened circumferentially on the outer peripheral wall of the arc-shaped brush rod 8. The end of the liquid-filled cavity 30 near the radial connecting rod 6 is connected to one end of the connector 32 fixedly installed on the radial connecting rod 6. The connector 32 has external threads and is threadedly connected to the threaded hole in the radial connecting rod 6, thereby facilitating the disassembly of the arc-shaped brush rod 8. The other end of the connector 32 is connected to the cleaning fluid tank 34 fixedly installed at the bottom of the workbench 1 through a liquid supply pipe 33. The liquid supply pipe 33 is a telescopic corrugated pipe, and its flexible telescopic performance can meet the reciprocating movement range of the arc-shaped brush rod 8. The cleaning fluid tank 34 contains cleaning fluid for cleaning the inside of the air tube sleeve, and a power pump is installed in the part of the liquid supply pipe 33 inside the cleaning fluid tank 34. In this embodiment, the power pump can be a common micro liquid pump, the purpose of which is to pump the cleaning liquid in the cleaning liquid tank 34 to the liquid supply pipe 33. The specific model and installation method of the power pump can be conventionally selected according to the flow rate and pressure requirements, and will not be described in detail in this specification.

[0030] In this embodiment, each brush 9 includes multiple flexible bristles evenly arranged along the outer periphery of the arc-shaped brush rod 8, and each brush 9 is evenly spaced from each set of liquid outlet holes 31. When the drive motor 4 drives the arc-shaped brush rod 8 to reciprocate, the brushes 9 on the arc-shaped brush rod 8 repeatedly rub against the inner wall of the tracheal sleeve 19, thereby brushing away the dirt adhering to the inner wall of the tracheal sleeve 19. At the same time, under the action of the corresponding power pump, the cleaning liquid in the cleaning liquid tank 34 is transported through the liquid supply pipe 33 and the connector 32 to the liquid passage chamber 30 of the arc-shaped brush rod 8, and sprayed outward from each liquid outlet hole 31, thereby cooperating with the brushes 9 to rinse and disinfect the inner wall of the tracheal sleeve 19.

[0031] A wastewater tank 35 is provided on the upper part of the workbench 1 below the main shaft 3 to hold the cleaning wastewater generated during the operation of the device. A drain pipe 36 is fixedly installed at the bottom of the wastewater tank 35 and connected to it, through which the wastewater in the wastewater tank 35 is discharged. A rinsing frame 37 is fixedly installed on the outside of the wastewater tank 35 on the workbench 1. A rinsing nozzle 38 is detachably mounted on the rinsing frame 37. The rinsing nozzle 38 is connected to an external water source through a rinsing water supply pipe 39. The rinsing water supply pipe 39 is a retractable corrugated pipe structure. After cleaning the inside of the air pipe sleeve, the operator removes the air pipe sleeve and turns on the rinsing nozzle 38 to further rinse the air pipe sleeve with clean water to ensure cleanliness. In addition, the rinsing nozzle 38 can also clean the arc-shaped brush rod and the brush.

[0032] The disinfection device includes a disinfection box 40 fixedly installed at the other end of the upper part of the workbench 1. A disinfection inlet pipe 55 and a disinfection outlet pipe 56 are fixedly installed and connected to the disinfection box 40. The disinfection inlet pipe 55 is connected to an external pure water source and is equipped with a water pump and an on / off valve; the disinfection outlet pipe 56 is connected to an external drainage pipe and is equipped with an on / off valve. A heater 41 is fixedly installed inside the disinfection box 40 near the lower end. The heater 41 is an electric heater used to heat and boil the pure water inside the disinfection box 40. A sealing lid 42 is provided on the upper part of the disinfection box 40. Specifically, two vertical electric cylinders 43 are symmetrically fixedly installed on the outer side of the disinfection box 40. Connecting ears 44 are fixedly provided on both sides of the sealing lid 42 at positions corresponding to the two electric cylinders 43. The two connecting ears 44 are fixedly connected to the telescopic ends of the corresponding electric cylinders 43. The opening and closing operation of the sealing lid 42 relative to the disinfection box 40 is achieved by the telescopic movement of the two electric cylinders 43. Two L-shaped placement racks 45 are symmetrically fixed at the bottom of the sealed box cover 42, and a disinfection basket 46 is placed on both placement racks 45.

[0033] In this example, the upper sides of the disinfection basket 46 are respectively fixedly provided with overlapping plates 47 that overlap with the two placement racks 45. A second limiting plate 48 perpendicular to the upper part of one end of each overlapping plate 47 near the placement rack 45 is fixedly provided. A sleeve 49 is fixedly provided on the opposite side of each of the two second limiting plates 48. A locking rod 50 is slidably mounted on each sleeve 49 and the corresponding second limiting plate 48. A limiting slide 51 is fixedly provided on the part of the locking rod 50 inside the sleeve 49, and a second spring 52 is sleeved on the locking rod 50 at the ends of the limiting slide 51 and the sleeve 49. A lifting head 53 is fixedly provided on one end of the locking rod 50, and the other end of the locking rod 50 is inserted into a locking hole 54 opened on the corresponding placement rack 45. When the disinfection basket 46 containing the cleaned tracheal cannula is placed inside the disinfection box 40 for boiling disinfection, the stability of the disinfection box 40 can be ensured by the insertion and locking relationship between the two locking rods 50 and the corresponding locking holes 54.

[0034] The working process of this invention is as follows: The operator places the tracheal cannula 19 to be cleaned onto the outside of the arc-shaped brush rod 8 and the brush 9. The tracheal cannula 19 is initially positioned using two upper positioning rollers 12 and the lower positioning roller 13. Then, two clamping motors 23 are activated to drive the corresponding bidirectional screws 22 to rotate. During the rotation of the bidirectional screws 22, the threaded sleeves 24 installed at both ends move towards each other, thereby driving the two clamping blocks 20 to move relative to each other via the sliding connecting rod 25, thus clamping the tracheal cannula 19. After the tracheal cannula 19 is positioned and clamped, the drive motor 4 is activated. The forward and reverse switching of the drive motor 4 causes the sector gear 7 to drive the radial connecting rod 6 and the arc-shaped brush rod 8 to reciprocate. When the arc-shaped brush rod 8 reciprocates, the brush 9 on the arc-shaped brush rod 8 repeatedly rubs against the inner wall of the tracheal cannula 19, thereby brushing away the dirt adhering to the inner wall of the tracheal cannula 19. Meanwhile, under the action of the power pump, the cleaning solution in the cleaning solution tank 34 is delivered through the supply pipe 33 and the connector 32 to the liquid passage chamber 30 of the arc-shaped brush rod 8, and sprayed outward from each liquid outlet 31, thereby cooperating with the brush 9 to rinse and disinfect the inner wall of the tracheal sleeve 19. After the rinsing and disinfection of the inner wall of the tracheal sleeve 19 is completed, the drive motor 4 stops, and the two clamping motors 23 drive the bidirectional screw 22 to rotate in opposite directions, causing the two opposing clamping blocks 20 to move in opposite directions and loosen their clamping effect on the tracheal sleeve 19, so that the staff can remove the tracheal sleeve 19 after the inner wall has been cleaned. After the staff removes the tracheal sleeve that has been cleaned internally, they turn on the rinsing nozzle 38 to further rinse the tracheal sleeve with clean water to ensure cleanliness. The rinsed tracheostomy tubes are then placed in a sterilization basket. This process is repeated to complete the cleaning and rinsing of a batch of tracheostomy tubes. Afterward, the staff places the sterilization basket 46 containing the tracheostomy tubes on two racks 45 and locks the basket in place using the locking rod 50 and locking hole 54. Then, two electric cylinders 43 simultaneously extend and retract to close the sealing lid 42, allowing the sterilization basket 46 to enter the sterilization chamber 40. The electric heater 41 is then activated to boil and sterilize the tracheostomy tubes 19 placed in the sterilization chamber 40.

[0035] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention.
