Description

Technical Field

[0002] As an effective means of artificially replacing the spontaneous ventilation function, ventilators have been widely used in modern clinical medicine. They are mainly used for respiratory failure caused by various reasons, anesthesia respiratory management during surgery, respiratory support therapy and emergency resuscitation, and they play a very important role in the field of modern medicine. Among them, the breathing tube of the ventilator is usually a corrugated tube. Due to the internal threaded structure, the breathing tube is not easy to clean.

[0003] The traditional way to clean the breathing tube is mainly manual cleaning. Although there are also automated cleaning equipment for cleaning breathing tubes in the prior art, such as the Chinese invention patent with announcement number CN108311483B, which sets an adjustment module, a clamping module, an outer wall cleaning module and an inner wall cleaning module to work together to achieve effective scrubbing of the inner and outer walls of the breathing tube, the technical solution still has the technical problem of low functionality. The disinfection and drying of the breathing tube after cleaning require additional equipment for processing, and it cannot be cleaned in one go, which makes the breathing tube prone to secondary contamination during transportation.

[0045] The nozzle unit 5 is arranged at the upper part of the equipment box 1 relative to the vertical axis of the clamping unit 4; it is worth noting that the nozzle unit 5 has a flushing state, a disinfection state and a drying state, and the flushing state, the disinfection state and the drying state are integrated in the same vertical axis through the integrated structure 8; wherein, the nozzle unit 5 includes a spray rod 501 that can be extended into the breathing tube, and a nozzle structure is arranged at the lower end of the spray rod 501, and the nozzle structure has a flow channel A and a flow channel B; the flow channel A is a side output flow channel for the outflow of cleaning water and disinfection foam; the flow channel B is a bottom output flow channel for the outflow of dry air.

[0046] like Figure 2 As shown, the mobile unit 6 is arranged inside the equipment box 1 on a side relative to the clamping unit 4, and the mobile end of the mobile unit 6 is fixedly connected to the fixed end of the nozzle unit 5; in an embodiment of the present invention, the mobile unit 6 is a conventional structure in the prior art in which a motor drives a screw to perform linear movement, and the fixed end of the spray rod 501 is fixedly connected to the mobile end of the screw linear moving structure through a connecting seat 9.

[0047] like Figure 1 As shown, the sewage discharge unit 7 is axially arranged at the lower part of the equipment case 1 relative to the clamping unit 4; in an embodiment of the present invention, the sewage discharge unit 7 includes a guide seat 701 fixedly arranged at the inner bottom of the equipment case 1, and the guide seat 701 is provided with a sewage discharge cavity relative to the position of the breathing tube. The sewage discharge cavity is connected to the outside through the sewage discharge port on the equipment case 1, which is used for the outflow of waste after cleaning the breathing tube.

[0048] like Figure 3 , Figure 4 and Figure 5 As shown, the integrated structure 8 includes a plurality of separation blocks A801 ​​and a plurality of separation blocks B802, and the plurality of separation blocks A801 ​​and the plurality of separation blocks B802 are staggered and spliced ​​to form a contact protrusion adapted to the inner wall of the breathing tube thread;

[0049] It is worth mentioning that the separation block A801 ​​and the separation block B802 can move upwards respectively; Figure 7 As shown, when the separation block A801 ​​is tightly connected with the separation block B802, the contact protrusion forms a fully closed brushing structure; Figure 8 As shown, when the separation block A801 ​​moves upward alone, the contact protrusion forms a half-open flushing structure; Fig. 9 As shown, when the separation block A801 ​​and the separation block B802 move upward in sequence, the contact protrusions form a fully open disinfection structure.

[0050] To achieve the above structural changes, specifically, Figure 4 , Figure 6 and Fig.10As shown, the integrated structure 8 also includes a central tube 803 fixedly arranged inside the spray rod 501 through a connecting protrusion, the lower end of the central tube 803 extends out of the lower end of the spray rod 501 and is fixedly connected to a base 804; the base 804 and the spray rod 501 are gap-matched to form a flow channel A, and the contact protrusion is arranged in the flow channel A; a Venturi tube cavity 805 is opened inside the central tube 803, and an air tube 807 is movably connected to the input end of the Venturi tube cavity 805, and the outer wall of the air tube 807 is movably sealed with the inner wall of the central tube 803, and the air tube The tail end of 807 is connected to a cylinder A806 fixed on the spray rod 501, and the input end of the air pipe 807 passes through the wall of the spray rod 501 through the ventilation pipeline and is connected to the external air supply mechanism. The output end of the venturi tube cavity 805 extends to the outside through the base 804, and the air pipe 807 cavity is connected to the venturi tube cavity 805 to form a flow channel B. The present invention utilizes the gradual structure of the venturi tube cavity 805, so that the air flow rate increases continuously as the cross-section of the venturi tube cavity 805 continues to shrink, and the air is more dispersed after being sprayed out from the air pipe 807.

[0051] Furthermore, a water inlet pipe 808 is sleeved on the outside of the air pipe 807, and the tail end of the water inlet pipe 808 is connected to the cylinder B826 fixed on the spray rod 501, and the input end of the water inlet pipe 808 passes through the wall of the spray rod 501 through the water supply pipeline and is connected to the external water supply mechanism; the upper outer side of the water inlet pipe 808 is rotatably connected with two sealing disks 809 in a parallel structure, which is conducive to the upper and lower isolation of this section of the structure; the sealing disk 809 slides linearly inside the spray rod 501 through the limiting protrusion 810, and the limiting protrusion 810 not only limits the sealing disk 809, but also limits the sealing disk 809. 09 can rotate, and can also provide supporting strength for the inner wall of the spray rod 501; a cleaning agent storage box 811 is sleeved between the two sealing disks 809 on the outside of the water inlet pipe 808, the cleaning agent storage box 811 is fixedly connected to the inner wall of the spray rod 501, and a cleaning agent outlet is provided on the sliding surface of the cleaning agent storage box 811 and the water inlet pipe 808, and a mixing inlet movably connected to the cleaning agent outlet is provided on the wall of the water inlet pipe 808, and the top of the cleaning agent storage box 811 passes through the wall of the spray rod 501 through a liquid supply pipeline and is connected to an external liquid supply mechanism.

[0052] The lower outer portion of the water inlet pipe 808 is rotatably connected to a mixing impeller 812. Figure 6 As shown, the mixing impeller 812 includes a bottom plate movably embedded on the outside of the water inlet pipe 808 and a plurality of blades on the bottom plate, wherein it is worth noting that the bottom plate is a hollow structure, which is conducive to drainage; a plurality of drainage ports 813 are provided in a circular shape at equal intervals on the lower wall surface of the water inlet pipe 808 relative to the position of the mixing impeller 812. When cleaning water and detergent are added to the water inlet pipe 808, when the two components are discharged through the drainage ports 813, the impact force of the liquid impacts the mixing impeller 812, and under the unloading effect of the curved surface of the blades, the impact force of the liquid drives the mixing impeller 812 to rotate, so that the cleaning water and detergent are fully integrated and form foam with cleaning and disinfecting effects.

[0053] It is worth mentioning that Figure 6 As shown, the positions of the outer wall of the central tube 803 relative to the plurality of separation blocks A801 ​​and the plurality of separation blocks B802 are slidably connected with an adjusting link A814 and an adjusting link B815 through limiting grooves, and the lower ends of the adjusting link A814 and the adjusting link B815 are movably connected with the separation blocks A801 ​​and B802 respectively through a quadrilateral connecting rod mechanism; the upper end of the adjusting link A814 is fixedly connected with the lower end of the water inlet pipe 808, and when the water inlet pipe 808 is pulled upward by the cylinder B826, the adjusting link A814 drives the separation block A801 ​​to move upward, and the quadrilateral connecting rod mechanism tends to fold under the tension, as shown in FIG. Figure 8 As shown, at this time, the contact protrusion forms a flushing structure in which the flow channel A is half-open, and the spray head unit 5 is in a flushing state that is convenient for flushing out the cleaning water.

[0054] The upper end of the adjusting link B815 is fixedly connected to the lower end of the air pipe 807. When the water inlet pipe 80 and the air pipe 807 are pulled upward by the cylinder B826 and the cylinder A806 respectively, the adjusting link A814 drives the separation block A801 ​​to move upward first, and then the adjusting link B815 drives the separation block B802 to move upward, and the contact protrusion forms a disinfection structure in which the flow channel A is fully opened. At this time, the nozzle unit 5 is in a disinfection state in which clean foam is flushed out;

[0055] When separation block A801 ​​is tightly connected with separation block B802, the contact protrusion forms a fully closed brushing structure of the circulation channel A. At this time, the nozzle unit 5 is in a dry state with air blown out. This fully closed structure is conducive to one-way blowing of air in the breathing tube, avoiding the problem of water droplets splashing due to air blowing on the inner wall of the breathing tube after cleaning and disinfection.

[0056] It is worth mentioning that Fig.14 As shown, a one-way output valve 816 is arranged in the cleaning agent outlet. Fig.12 As shown, a one-way input valve 817 is arranged in the mixing inlet; when the contact protrusion is fully closed, the one-way output valve 816 and the one-way input valve 817 not only have a height difference, but also have a position distribution in opposite directions; when the contact protrusion is fully opened, the one-way output valve 816 and the one-way input valve 817 are docked opposite to each other at the same horizontal height; in addition, a docking groove 820 with a small depth is left between the inlet of the one-way output valve 816 and the outer diameter of the cleaning agent outlet, and the outlet of the one-way input valve 817 is connected to a docking seat 819 through an elastic member 818 (which can be a spring), and the docking seat 819 is movably engaged with the docking groove 820, which is beneficial to the interface docking of the one-way output valve 816 and the one-way input valve 817, thereby reducing the possibility of leakage; it is worth noting that the docking seat 819 is a square structure and the outer surface has rounded corners.

[0057] It is worth noting that Fig.12 As shown, the water inlet pipe 808 is a multi-section pipeline structure, including a pipe body A827 fixedly connected to the adjusting connecting rod A814, a pipe body B828 fixedly connected to the water supply pipeline, and a pipe body C829 rotatably connected to the pipe body A827 and the pipe body B828; the sealing disk 809 located on the upper side is fixedly connected to the pipe body B828, and the sealing disk 809 located on the lower side is fixedly connected to the pipe body A827, and the mixing inlet is arranged on the pipe body C829; the inner wall of the pipe body C829 is provided with a guide groove 821 relative to the position of the detergent storage box 811, and the outer wall of the air pipe 807 is fixedly connected with a ejector pin 825 (a kind of elastic round-head telescopic structure in the prior art, such as Fig.14 The guide groove 821 is composed of a vertical slide groove 822 and a curved groove 823. The height of the vertical slide groove 822 is adapted to the moving height of the separation block A801, so that when the water inlet pipe 808 is pulled upward by the cylinder B826, the ejector pin 825 slides down to the low point along the vertical slide groove 822 and enters the curved groove 823; the spiral height of the curved groove 823 is adapted to the moving height of the separation block B802, so that when the air pipe 807 is pulled upward by the cylinder A806, the ejector pin 825 squeezes the inclined surface in the curved groove 823 to cause the rotation of the tube body C829, so that the one-way input valve 817 on the tube body C829 is docked with the one-way output valve 816.

[0058] It is worth noting that in the present invention, the lower end of the curved groove 823 is connected to the lower end of the vertical slide groove 822 to form a stepped structure in which the depth of the curved groove 823 is greater than the depth of the vertical slide groove 822, so that the ejector pin 825 slides down from the vertical slide groove 822 into the curved groove 823. At this time, the ejector pin 825 is extended into the curved groove 823, which is beneficial for the ejector pin 825 to actively squeeze the inner wall of the curved groove 823 when the air pipe 807 is pulled upward by the cylinder A806, thereby causing the tube body C829 to rotate.

[0059] In addition, in the present invention, a cross groove 824 is provided on the sliding surface of the cleaning agent storage box 811 and the water inlet pipe 808, the cross groove 824 is in sliding contact with the docking seat 819, and the clearance height of the docking seat 819 constrained by the cross groove 824 is smaller than the sliding length of the ejector pin 825 on the step structure; through the above arrangement, when the water inlet pipe 808 is pulled upward by the cylinder B826, the docking seat 819 follows the tube body C829 upward until it reaches the intersection of the cross groove 824, as shown in FIG. Fig.14position; when the air pipe 807 is pulled upward by the cylinder A806, based on the relative extrusion of the ejector pin 825 and the curved groove 823, the docking seat 819 is ejected into the docking groove 820 after axial rotation, and the one-way output valve 816 and the one-way input valve 817 are interfaced; after the external liquid supply mechanism pumps the cleaning agent, the cleaning agent flows into the one-way input valve 817 through the one-way output valve 816, and then enters the water inlet pipe 808; when the above action is returned, the air pipe 807 is pushed downward by the cylinder A806, the curved groove 823 actively moves downward and is squeezed by the ejector pin 825 to force the tube body C829 to rotate and reset, and the docking seat 819 comes to the intersection of the cross groove 824 again, as shown in FIG. Fig.14 position; when the water inlet pipe 808 is pushed downward by the cylinder B826, the docking seat 819 begins to slide in the radial groove direction of the cross groove 824, and the gap height a gradually decreases. At the same time, the ejector pin 825 slides on the stepped structure, but is limited by the depth of the step and cannot go out from the deep curved groove 823 to the shallow vertical slide groove 822. At this time, under the influence of the squeezing of the curved groove 823, the tube body C829 has the possibility of secondary axial rotation; but when the docking seat 819 slides into the radial groove of the cross groove 824, it is limited by the side wall of the radial groove and the clearance height of the constraint is less than the sliding length of the ejector pin 825 on the stepped structure, and the docking seat 819 can only slide downward in a straight line. At this time, the ejector pin 825, which is still sliding on the stepped structure, is constrained by the movement of the docking seat 819 and has to go out from the vertical slide groove 822 inward of the curved groove 823, so that the water inlet pipe 808 can be reset downward.

[0060] Working principle: This embodiment provides a breathing tube cleaning, disinfecting and drying machine. When in use, open the movable door on the front of the equipment box 1, straighten the breathing tube to be cleaned and clamp it on the two tube clamps in sequence, and close the movable door; drive the lower end of the nozzle unit 5 to extend into the inner side of the upper part of the breathing tube through the movable unit 6; use the cylinder B826 to pull the water inlet pipe 808 upward, at this time, the tube body A827, the tube body B828 and the tube body C829 move upward as a whole, and the adjusting connecting rod A814 is pulled by the tube body A827 to move linearly upward on the surface of the central tube 803, and the lower end of the several separation blocks A801 ​​movably connected by the quadrilateral connecting rod mechanism are pulled into the inner side of the lower end of the spray rod 501. The contact protrusion forms a flushing structure in which the flow channel A is half open. Water is pumped by an external water supply mechanism, and the cleaning water is ejected laterally from the half-open flow channel A and impacts the inner wall of the breathing tube. At the same time, the ejector pin 825 slides along the vertical slide groove 822 to the lowest point, thereby entering the curved groove 823. The moving unit 6 is then used to reciprocate and drive the nozzle unit 5 to move up and down, so that the inner wall of the breathing tube can be evenly flushed. After the breathing tube is cleaned, the air tube 807 is pulled upward by the cylinder A806, and the ejector pin 825 squeezes the inclined surface in the curved groove 823 to cause the tube body C829 to rotate, causing the one-way input valve 817 on the tube body C829 to dock with the one-way output valve 816. When the air pipe 807 is in the air, the adjusting connecting rod B815 fixedly connected to the air pipe 807 drives the separation block B802 to move upward, and contacts the protrusion to form a disinfection structure with the circulation channel A fully opened. Then, the cleaning liquid is pumped into the external liquid supply mechanism, so that the cleaning liquid can flow down in the water inlet pipe 808. After the water supply mechanism pumps water, the cleaning water and the cleaning liquid are discharged through the drain port 813. The impact force of the liquid impacts the mixing impeller 812. Under the unloading effect of the curved surface of the blade, the impact force of the liquid drives the mixing impeller 812 to rotate, so that the cleaning water and the detergent are fully integrated and form a foam with cleaning and disinfecting effects. This disinfecting foam flows out laterally from the fully opened circulation channel A and adheres to the inner wall of the breathing tube. The moving unit 6 reciprocatingly drives the nozzle unit 5 to move up and down, and the disinfection foam can be evenly adhered to the inner wall of the breathing tube; based on the directional operation of the above-mentioned action, the separation block A801 ​​and the separation block B802 can be reconnected tightly, and the contact protrusion forms a fully closed brushing structure of the flow channel A. The moving unit 6 reciprocatingly drives the nozzle unit 5 to move up and down, and the inner wall of the breathing tube can be reciprocated and brushed. By utilizing the adaptability of the contact protrusion and the inner wall of the breathing tube thread, the disinfection and cleaning of the inner wall of the breathing tube thread can be increased, which is beneficial to improving the cleaning effect; finally, dry air is pumped into the breathing tube through the external air supply mechanism, so as to achieve blowing and draining of the inner wall of the breathing tube, thereby achieving drying of the breathing tube.
