Description

Technical Field

[0001] This utility model relates to the field of sputum suction device technology, and in particular to a sputum suction device for respiratory medicine. Background Technology

[0002] Suctioning devices are commonly used medical equipment in respiratory medicine. Their main function is to help patients clear secretions from the airway, such as sputum, blood, or food residue, in order to keep the airway clear and prevent aspiration pneumonia.

[0003] Patent specification CN218589434U discloses an emergency suction device for respiratory medicine, including a device body. A mounting plate is fixedly connected to the middle of the bottom of the device body. Connecting plates are threadedly connected to both sides of the mounting plate via connecting bolts. A first leg and a second leg are fixedly connected to the middle of the two connecting plates, respectively. A connector is fixedly connected to the middle of one side of the device body. This utility model, an emergency suction device for respiratory medicine, adds a supporting structure to the device body by setting up the mounting plate, connecting blocks, first leg, and second leg. When using it, the user can install the first leg and second leg, place the device body on the bed frame, pull the piston with one hand, and insert the suction tube into the patient's throat with the other hand. It is more convenient to use and there is no need to worry about the user losing control of the device body and causing an accident. Furthermore, the setting of connecting tube and connector makes it easy to disassemble and clean the device body, making it more convenient to use.

[0004] However, during the implementation of the relevant technology, the above-mentioned emergency suction device for respiratory medicine has the following problems: When the device removes foreign objects from the patient's throat, one hand needs to insert the suction tube into the patient's throat, and the other hand needs to manually pull the lever. This operation is prone to the device moving because the piston resistance exceeds the weight of the device itself. However, the automatic suction devices on the market are large, have high manufacturing costs, and are not easy to carry, making them unsuitable for use in hospitals with limited medical resources. In view of this, a suction device for respiratory medicine is provided to overcome the above defects. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a sputum suction device for respiratory medicine.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a suction device for respiratory medicine, comprising a suction tube, an installation head engaged on the outer side of the top left end of the suction tube, a sputum storage container fixedly connected to the bottom of the installation head, a suction tube fixedly connected to the left end face of the installation head, a bracket fixedly connected to the lower right side of the suction tube, a one-way valve fixedly connected to the middle of the upper left end of the suction tube, a piston slidably connected to the inner wall of the suction tube, a connecting block fixedly connected to the right end face of the piston, a turntable fixedly connected to the right end face of the connecting block, a threaded rod fixedly connected to the middle of the right end face of the turntable, a fixed plate fixedly connected to the top right side of the inner wall of the suction tube, a sliding groove opened on the right side of the fixed plate, a rotating block slidably connected to the inner wall of the sliding groove on the right side of the fixed plate, a linkage gear fixedly connected to the right end face of the rotating block, an internal thread provided inside the linkage gear, a housing fixedly connected to the outer right side of the suction tube, a micro motor fixedly connected to the upper left side of the housing, and a drive gear fixedly connected to the output end of the micro motor.

[0007] As a further description of the above technical solution: the fixed plate is rotatably connected to the outside of the threaded rod while sliding inside the middle of the fixed plate; the internal thread of the linkage gear is helically connected to the outside of the threaded rod; the left end face of the linkage gear is in contact with the right end face of the fixed plate; the lower part of the drive gear meshes with the upper part of the linkage gear; the middle of the top right side of the suction tube is fixedly connected to the bottom of the micro motor; the lower right side of the housing is rotatably connected to the outside of the threaded rod while sliding inside the housing. This can drive the linkage gear on the right end face of the suction tube to rotate, and cause the internal thread of the linkage gear to drive the threaded rod to rotate, thereby automatically driving the piston in the suction tube to perform suction operation. This frees the operator's hands and makes it easier to insert the suction tube into the patient's throat.

[0008] As a further description of the above technical solution: the output end of the micro motor is provided with an output shaft, and the end of the output shaft away from the micro motor is fixedly connected to the middle of the left end face of the drive gear. The tooth pitch of the drive gear is one-third of the tooth pitch of the linkage gear, so that the drive gear drives the linkage gear to rotate, thereby realizing the purpose of the threaded rod driving the piston to move in the suction pipe.

[0009] As a further description of the above technical solution: the length of the threaded rod matches the left and right lengths of the suction pipe, and through holes are provided in the middle of the inside of the fixed plate and the lower middle of the inside of the housing. The diameter of the through holes matches the longitudinal section diameter of the threaded rod, allowing the threaded rod to pass through the fixed plate and the housing, thus preventing the fixed plate and the housing from affecting the normal movement of the threaded rod.

[0010] As a further description of the above technical solution: the cross-sectional shape of the connecting block is T-shaped, the left end face of the connecting block is fixed to the right end face of the piston by adhesive, and the right end face of the connecting block is fixed to the left end face of the turntable by welding.

[0011] As a further description of the above technical solution: the cross-sectional shape of the rotating block is convex, the number of the rotating blocks is two sets, and the rotating blocks are distributed at the upper and lower ends of the linkage gear. The cross-sectional shape of the sliding groove inside the fixed disk corresponds to the cross-sectional shape of the rotating block, which can achieve the purpose of preventing the linkage gear from being removed while rotating on the right end face of the fixed disk.

[0012] As a further description of the above technical solution: the one-way valve can only perform exhaust operation. The top of the bracket is fixed to the outside of the exhaust pipe near the housing. The one-way valve can exhaust the gas in the exhaust pipe when the piston is inside the exhaust pipe and moves from right to left. The one-way valve closes when the piston is outside the exhaust pipe and moves from left to right to avoid gas leakage.

[0013] This utility model has the following beneficial effects:

[0014] This invention relates to a respiratory medicine suction device. Through the design and coordination of a micro motor and a drive gear, the device can drive the linkage gear on the right end of the suction tube to rotate, and the internal thread in the middle of the linkage gear drives the threaded rod to rotate, thereby automatically driving the piston in the suction tube to perform the suction operation. This frees the operator's hands and makes it easier to insert the suction tube into the patient's throat. Compared with large suction devices, the device of this application has the advantages of small size, easy portability, low cost, and automatic suction, and is suitable for widespread use.

[0021] Reference Figures 1 to 4This utility model provides a sputum suction device for respiratory medicine, including a suction tube 1. The outer side of the left top of the suction tube 1 is fitted and secured by an installation head 2. A sputum storage container 3 is located at the bottom of the installation head 2. A suction tube 4 is located on the left end face of the installation head 2. A bracket 5 is fixed to the lower right side of the suction tube 1 by bolts. A one-way valve 6 is located in the middle of the upper left side of the suction tube 1. A piston 9 is inserted into the inner wall of the suction tube 1 and slides laterally. A connecting block 16 is glued to the right end face of the piston 9. A turntable 10 is welded to the right end face of the connecting block 16. A threaded rod 8 is welded to the middle of the right end face of the turntable 10. A fixing plate 11 is welded to the top right side of the inner wall of the suction tube 1. A sliding groove 15 is formed on the right side of the inside of the fixing plate 11. A rotating block 17 is inserted into and slides through the inner wall of the sliding groove 15 on the right side of the fixing plate 11. A linkage gear 12 is welded to the right end face of the rotating block 17. The linkage gear 12 has an internal thread 18. A housing 7 is fixed to the outer right side of the suction tube 1 by bolts. The micro motor 13 is fixed to the upper left side of the housing 7 by bolts. The output shaft of the micro motor 13 is welded to the top active gear 14. The middle of the fixed plate 11 is rotatably connected to the outer side of the threaded rod 8 while sliding. The internal thread 18 in the middle of the linkage gear 12 is helically connected to the outer side of the threaded rod 8. The left end face of the linkage gear 12 contacts the right end face of the fixed plate 11. The lower part of the active gear 14 meshes with the upper part of the linkage gear 12. The middle of the upper right side of the suction tube 1 is fixedly connected to the bottom of the micro motor 13. The lower right side of the housing 7 is rotatably connected to the outer side of the threaded rod 8 while sliding. This can drive the linkage gear 12 on the right end face of the suction tube 1 to rotate, and the internal thread 18 in the middle of the linkage gear 12 drives the threaded rod 8 to rotate, realizing the automatic driving of the piston 9 in the suction tube 1 to perform the suction operation. The operator is freed from hands and can more easily insert the suction tube 4 into the patient's throat.

[0022] As a further implementation of the above technical solution: the output end of the micro motor 13 is provided with an output shaft, and the end of the output shaft away from the micro motor 13 is fixedly connected to the middle of the left end face of the drive gear 14. The tooth pitch of the drive gear 14 is one-third of the tooth pitch of the linkage gear 12, so that the drive gear 14 can drive the linkage gear 12 to rotate, thereby realizing the purpose of the threaded rod 8 driving the piston 9 to move in the suction pipe 1.

[0023] As a further implementation of the above technical solution: the length of the threaded rod 8 matches the left and right lengths of the suction pipe 1. Through holes are provided in the middle of the inside of the fixed plate 11 and the lower middle of the inside of the housing 7. The diameter of the through holes matches the longitudinal section diameter of the threaded rod 8, allowing the threaded rod 8 to pass through the fixed plate 11 and the housing 7, thus preventing the fixed plate 11 and the housing 7 from affecting the normal movement of the threaded rod 8.

[0024] As a further implementation of the above technical solution: the cross-sectional shape of the connecting block 16 is T-shaped, the left end face of the connecting block 16 is fixed to the right end face of the piston 9 by adhesive, and the right end face of the connecting block 16 is fixed to the left end face of the turntable 10 by welding.

[0025] As a further implementation of the above technical solution: the cross-sectional shape of the rotating block 17 is convex, there are two sets of rotating blocks 17, and the rotating blocks 17 are distributed at the upper and lower ends of the linkage gear 12. The cross-sectional shape of the sliding groove 15 inside the fixed disk 11 corresponds to the cross-sectional shape of the rotating block 17, so that the linkage gear 12 cannot be removed while rotating on the right end face of the fixed disk 11.

[0026] As a further implementation of the above technical solution: the one-way valve 6 can only perform exhaust operation. The top of the bracket 5 is fixed to the outside of the exhaust pipe 1 near the housing 7. The one-way valve 6 can exhaust the gas in the exhaust pipe 1 when the piston 9 is in the exhaust pipe 1 and moves from right to left. The one-way valve 6 closes when the piston 9 is out of the exhaust pipe 1 and moves from left to right to avoid gas leakage.

[0027] Working principle:

[0028] When using this invention, the mounting head 2 is fitted onto the outer side of the left top of the suction tube 1. The suction tube 1 is then placed near the patient who needs suctioning. The suction tube 4 on the left end of the mounting head 2 is inserted into the patient's throat. Once in position, the micro motor 13 located on the upper part of the housing 7 on the right side of the suction tube 1 is activated. The micro motor 13 drives the output gear 14 to rotate, which in turn drives the meshing linkage gear 12 below to rotate synchronously. The rotating block 17 on the left end of the linkage gear 12 slides within the groove 15 on the right end of the fixing plate 11 at the top right side of the suction tube 1. At this time, the internal thread 18 inside the linkage gear 12... The threaded rod 8, connected by a rotating screw, moves from left to right. The threaded rod 8, through the turntable 10 and connecting block 16, drives the piston 9 to move from left to right within the suction tube 1. The negative pressure generated within the suction tube 1 draws foreign objects from the patient's throat into the mounting head 2 and suction tube 4, where they fall into the sputum collection container 3. When the piston 9 moves to the top right side of the suction tube 1, the micro motor 13 reverses direction, and the piston 9 moves from right to left within the suction tube 1. At this time, the gas in the inflation tube is discharged outward through the one-way valve 6, leaving only a small amount of gas to enter the patient's throat through the suction tube 4, but this has no effect. This cycle continues until the foreign objects in the patient's throat are completely cleared.

[0029] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
