Description

Technical Field

[0001] The present invention relates to the field of sputum aspiration, and specifically to a sputum aspiration device and a method for using the same. Background Art

[0002] In clinical practice, when there is too much thick sputum and viscous fluid in the throat of pediatric patients, the sputum and viscous fluid block the respiratory tract, causing difficulty in breathing. If not treated in time, a critical situation of pediatric asphyxia and death will occur.

[0003] Currently, most of the respiratory tracts are cleared by using sputum aspiration devices. However, the existing pediatric sputum aspiration devices directly aspirate sputum into the respiratory tract of children. The viscosity of the sputum is very high, and a large suction force is required to aspirate the undiluted sputum, which will cause serious discomfort to children during the sputum aspiration process. At the same time, during the process of inserting the suction tube into the sputum aspiration position, visual operation cannot be performed, making it difficult for the suction tube to accurately reach the place where sputum needs to be aspirated, resulting in an unsatisfactory sputum aspiration effect. Moreover, the respiratory tract of children is relatively more fragile than that of adults, so special attention needs to be paid to the time of using the sputum aspiration device for sputum aspiration.

[0041] In order to enable those skilled in the art of the present technology to better understand the solution of this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.

[0042] Embodiment 1

[0043] Please refer to Figure 1 - Figure 11, A sputum suction device, comprising a housing 1, an adjustable sputum suction device 3, an atomizer 4, an insertion tube, a display screen 15 and an electronic timer 19. Cavities for placing a detection tank 2, an adjustable sputum suction device 3 and an atomizer 4 are respectively formed inside the housing 1. A support ring 5 for placing a sputum suction tank 6 is fixed to the upper end of one side of the adjustable sputum suction device 3. Sealing covers 7 are provided at the upper ends of both the sputum suction tank 6 and the detection tank 2. The sealing cover 7 installed at the upper end of the sputum suction tank 6 is respectively communicated with a negative pressure tube 8 and a connecting tube 9. The other end of the negative pressure tube 8 is connected to the negative pressure nozzle of the pump body inside the adjustable sputum suction device 3. The other end of the connecting tube 9 is communicated with the first docking nozzle 10 of the insertion tube through a pipe clamp. The inside of the first docking nozzle 10 is communicated with the sputum suction cavity in the middle of the insertion tube. An atomized liquid cavity for diluting sputum is also formed in the middle of the insertion tube. One side of the atomized liquid cavity is communicated with a telescopic tube 12 through a second docking nozzle 11 and a pipe clamp. The other end of the telescopic tube 12 is fixed to the mouth of the atomized medicine tank of the atomizer 4 through the housing 1 and a pipe clamp;

[0044] An inner cavity for placing an endoscope 13 and a lighting lamp 14 is formed inside the wall of the insertion tube. Perspective protection covers are fixed at the ends of both inner cavities. The tail end of the endoscope 13 passes through the inner cavity through a wire and is connected to the display screen 15;

[0045] The exhaust nozzle of the adjustable sputum aspirator 3 is connected to a treatment tube 16. The other end of the treatment tube 16 penetrates into the interior of the filter box 17. The filter box 17 is fixed inside the cavity by screws. The front end of the adjustable sputum aspirator 3 is provided with a control panel 18. The control panel 18 is also connected to an electronic timer 19 through a wire. A speaker 20 is installed at the front end of the electronic timer 19. First, considering that existing pediatric sputum aspiration devices directly aspirate sputum into the respiratory tract of children, the viscosity of the sputum is very high. Sputum that has not been diluted requires a large suction force to be aspirated, which will cause severe discomfort to children during the sputum aspiration process. The insertion tube of the present invention adopts a double-chamber design. Therefore, before sputum aspiration, the atomized liquid medicine for diluting sputum can be transported to the sputum aspiration position through the nebulizer 4 and the telescopic tube 12, so as to moisten the viscous sputum, and then it is easy to aspirate the diluted sputum when using the insertion tube for sputum aspiration; Second, considering that during the process of inserting the suction tube into the sputum aspiration position, visual operation cannot be performed, making it difficult for the suction tube to accurately reach the place where sputum needs to be aspirated, resulting in an unsatisfactory sputum aspiration effect. The present invention can use the lighting lamp 14 and the endoscope 13 at the end of the insertion tube in cooperation with the display screen 15 on the upper end of the gripper 40 to perform visual operation on the process of inserting the insertion tube, thereby helping the insertion tube to reach the sputum aspiration position smoothly, avoiding discomfort caused by touching the child's respiratory tract during the insertion of the pipeline, and the visual operation helps medical staff to accurately insert the insertion tube into the sputum aspiration position for sputum aspiration operation. Finally, considering that the respiratory tract of children is relatively fragile compared to that of adults, so the time for using the sputum aspiration device for sputum aspiration needs to be particularly noted. The present invention realizes the timing function of the negative pressure intensity, the suction time and the interval time for aspirating sputum by using the adjustable sputum aspirator 3 with adjustable negative pressure and the electronic timer 19, effectively avoiding the situation of damage to the respiratory mucosa of children caused by too long sputum aspiration time and too large negative pressure intensity. When the duration of the electronic timer 19 reaches, the speaker 20 can make a sound to remind the device operator.

[0046] Please refer particularly to Figure 1 and Figure 7 As shown, fixed buckles 21 are rotatably connected to both sides of the two sealing covers 7. Sealing rings 22 that contact the inner walls of the detection tank 2 or the sputum aspiration tank 6 are installed on the outer parts of the lower ends of the two sealing covers 7. And fixing sleeves 23 through which pipelines penetrate are fixed to the upper ends of the sputum aspiration tank 6 and the adjustable sputum aspirator 3. By setting the fixed buckles 21, it plays a role in conveniently fixing the connection between the sealing covers 7 and the detection tank 2 and the sputum aspiration tank 6. The presence of the sealing rings 22 improves the sealing performance of the sealing covers 7.

[0047] Please refer particularly to Figure 1 and Figure 7As shown, a threaded cap 24 for abutting against the annular gasket is threadedly connected to the upper end of each fixed sleeve 23. A reserved hole adapted to the outer dimensions of the connecting pipe 9, the negative pressure pipe 8, and the treatment pipe 16 is penetrated through the middle of the threaded cap 24, and a positioning ring 25 is fixedly sleeved on the outer parts of the connecting pipe 9, the negative pressure pipe 8, and the treatment pipe 16. By setting the threaded cap 24 to cooperate with the fixed sleeve 23, the positioning ring 25 is fixed. After the fixing ring is fixed by the extrusion of the threaded cap 24 and the fixed sleeve 23, the loosening of the connecting pipe 9, the negative pressure pipe 8, and the treatment pipe 16 is effectively prevented.

[0048] Please refer specifically to Figure 1 、 Figure 4 、 Figure 8 and Figure 11 As shown, a positioning bolt 26 for fixing the sputum suction can 6 is threadedly connected to the front end of the supporting ring 5. A kit 28 for threadedly connecting the filter element 27 is fixedly installed in the middle of the sputum suction can 6. Both sides of the upper end of the filter element 27 are fixedly provided with convex ends 29 for the user to turn. A relief hole for the connecting pipe 9 to penetrate is penetrated through one side of the middle of the filter element 27. A sunken hole for placing the waterproof and breathable membrane 30 is provided on the other side of the middle of the filter element 27. A limiting ring 31 for abutting against the waterproof and breathable membrane 30 is threadedly connected to the upper end of the sunken hole. External threads adapted to the internal thread grooves of the sunken hole are provided on the limiting ring 31. By setting the waterproof and breathable membrane 30, the sputum is prevented from being sucked into the treatment pipe 16 through negative pressure, playing an insulating role, that is, the sputum remains inside the sputum suction can 6, and the gas enters the inside of the filter box 17 through the treatment pipe 16.

[0049] Please refer specifically to Figure 1 、 Figure 3 and Figure 10 As shown, reserved slots for installing the plug boards 32 are provided at both the upper and lower ends inside the filter box 17. Lamp sockets 34 for installing the ultraviolet disinfection lamp strips 33 are fixedly installed on the opposite surfaces of the two plug boards 32. Transparent covers are covered on the opposite surfaces of the two lamp sockets 34, and card strips 36 for installing the air filter plates 35 are equally spaced and fixedly installed on the opposite surfaces of the two transparent covers. The card strips 36 are made of a transparent material. A discharge pipe 37 is installed on the other side of the filter box 17. The gas sucked out during the sputum suction process will be filtered by multiple air filter plates 35 and then discharged. Since the air filter plates 35 need to filter the discharged gas, bacteria may adhere to the air filter plates 35. When the device is not in use, the multiple air filter plates 35 will be disinfected by the ultraviolet disinfection lamp strips 33.

[0050] Please refer specifically to Figure 1 and Figure 9As shown, the front end of the shell 1 is fixed to the dustproof perspective plate 38 by screws, and an embedding groove for installing the air permeable net 39 is opened at the front end of the dustproof perspective plate 38. Considering that dust may enter the cavity when the device is not used for a long time, the dustproof perspective plate 38 will be fixed to the front end of the shell 1 by screws when the device is not used for a long time, so as to provide dustproof protection for the cavity. When the device is used, the screws need to be loosened and the dustproof perspective plate 38 needs to be removed, so as to facilitate the user to operate the equipment inside the cavity.

[0051] Please refer to Figure 1 , Figure 5 and Figure 6 As shown, a holder 40 is provided above the shell 1, and a positioning cavity for placing the insertion tube is opened through the inner part of the upper end of the holder 40, and the upper end of the positioning cavity is threadedly connected with a limit bolt 41, and the bottom of each limit bolt 41 is rotatably connected to the upper end of the resistance member 42 through a bearing, and a first rubber pad 43 is fixed to the lower surface of the resistance member 42, and a pad 44 is provided at the lower end of the inner part of the positioning cavity for contact with the surface of the insertion tube, and a second rubber pad 45 is fixed to the upper end of the two pads 44. The positioning is performed to position the insertion tube placed in the positioning cavity of the holder 40 by setting the limit matching resistance member 42 and the pad 44, which is convenient for medical staff to check the insertion process through the display above the holder 40 during the process of placing the insertion tube into the patient's respiratory tract.

[0052] Please refer to Figure 1 , Figure 5 and Figure 6 As shown, a support plate 47 is hingedly connected to the upper end of the holder 40 through a damping shaft 46, a groove for installing the display screen 15 is provided at the upper end of the support plate 47, and adsorption pads 48 are fixed to the bottom of the support plate 47 and the shell 1, and a magnetic block 49 is provided inside each adsorption pad 48. By arranging the support plate 47 to be installed with the damping shaft 46, it is convenient for medical staff to rotate the support plate 47 as needed to adjust the use angle of the display, thereby facilitating medical staff to check.

[0053] Please refer to Figure 1 As shown, a backup power module 50 for providing power to the display screen 15 is installed inside the holding end of the holder 40. The backup power module 50 is connected to the power supply interface on the side end of the holder 40 through a wire, and the backup power passes through the side of the holder 40 through the wire and is connected to the circuit of the lighting lamp 14. By setting up the backup power supply, when the external power supply is far away, the backup power supply can be used to supply power to the display screen 15, the lighting lamp 14 and the endoscope 13, and the backup power supply can be recharged through the power supply interface.

[0054] Embodiment 2

[0055] The present invention provides a method for using a sputum suction device, comprising the following steps:
