Description

Technical Field

[0001] The present invention relates to the technical field of sputum aspiration treatment devices, and particularly to a sputum aspiration treatment device for pediatric surgical care. Background Art

[0002] In pediatric surgical care, sputum aspiration treatment is one of the common operations, mainly used to remove sputum in the respiratory tract, keep the respiratory tract unobstructed, and prevent complications such as respiratory tract infections. During the sputum aspiration treatment process, the stent plays a crucial role. The stent is mainly used to fix the sputum aspiration device and related components to ensure its stability during the operation.

[0003] Chinese Patent (Publication No.: CN119139571B), this solution specifically includes a left bottle, a right bottle, an air delivery mechanism, a mounting bracket, and a commutation mechanism. To improve the sputum aspiration efficiency and reduce the discomfort of patients, a single-tube delivery method is adopted, which can perform sputum aspiration treatment and expectoration treatment on patients respectively, reduce the number of tubes inserted into the affected area, and at the same time, the steps of pulling out and inserting the tube and expectoration treatment when dealing with thick sputum can be optimized, shortening the treatment time while improving the sputum aspiration efficiency, solving the problems that the traditional sputum aspiration device cannot perform expectoration treatment and there are too many tubes inserted into the affected area during sputum aspiration treatment. At the same time, the adjustment methods for sputum aspiration and expectoration are simple, only need to switch the coil magnet and exchange the trigger judgments of the left trigger and the right trigger, which helps medical staff master the usage method faster, improve work efficiency, and save precious time.

[0004] The sputum aspiration treatment device in the above patent mainly discharges sputum from the patient's respiratory tract through negative pressure suction. However, when used in pediatrics, it lacks the optimization and adjustment of the child's body position, cannot make full use of the gravity effect to promote sputum discharge, and fails to effectively combine auxiliary sputum discharge means such as back patting, resulting in low sputum discharge efficiency and easy irritation to the child's respiratory tract. At the same time, the existing postural drainage methods are mostly manual operations, which are difficult to achieve precise body position adjustment and continuous body position changes, thus difficult to meet the sputum discharge needs of children with viscous sputum.

Specific embodiments

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0035] Please refer to Figures 1 to 9 , the present invention provides a technical solution: a sputum suction treatment device for pediatric surgical care, including a base 1 and legs 2 for adjusting the horizontal height of the base 1, and further including a body plate 3 provided on the base 1 and an intubation tube provided thereon for penetrating into the respiratory tract of children. A body position adjustment mechanism for adjusting the body position of children to promote expectoration is provided on the base 1;

[0036] The body position adjustment mechanism comprises an axis seat 4 fixedly connected to the base 1, a positioning worm wheel 5 is fixedly connected to the axis seat 4, the body plate 3 comprises an integrally formed shaft swing portion 301 at a position corresponding to the axis seat 4, an arc groove for sliding connection of the shaft swing portion 301 is provided on the axis seat 4, a U-shaped support seat 7 is fixedly connected to the body plate 3, a vertical axis 6 is fixedly rotated on the U-shaped support seat 7, and a swing worm 8 meshingly connected to the positioning worm wheel 5 is fixedly sleeved on the vertical axis 6;

[0037] The body plate 3 is provided with a negative pressure cylinder 28 in communication with the cannula gas, and the body plate 3 is provided with a negative suction component for driving the negative pressure cylinder 28 to suck the gas in the cannula;

[0038] An arc-shaped elastic patting seat 19 for patting the child's back is provided on the upper surface of the body plate 3, and a patting component is provided on the body plate 3 for adjusting the distance between the arc-shaped elastic patting seat 19 and the upper surface of the body plate 3 when its own orientation changes. An avoidance groove is opened in the middle of the body plate 3, and a pushing component is provided at the avoidance groove for supporting the child's lower jaw to promote unobstructed airway.

[0039] like Figures 1 - 3 As shown, when suctioning a child, the child is made to stand on the base 1 and the body plate 3, with the child's face facing the side of the body plate 3, and the intubation tube is inserted into the child's respiratory tract to a certain depth, wherein the support leg 2 is a telescopic leg structure, and the height of the support leg 2 is adaptively adjusted according to the child's height so that the connection position of the body plate 3 and the support leg 2 is roughly at the child's waist position.

[0040] At the same time, the vertical shaft 6 connected to the motor output shaft by the motor drive fixed on the body plate 3 rotates, wherein the swing worm 8 is meshedly connected with the positioning worm wheel 5, and the positioning worm wheel 5 is fixedly connected to the base 1 through the axis seat 4, and then when the vertical shaft 6 drives the swing worm 8 to rotate, it can drive the shaft swing part 301 integrally formed on the body plate 3 to rotate on the axis seat 4, thereby changing the angle between the body plate 3 and the base 1. In the initial state, the body plate 3 is vertically downward. As the vertical shaft 6 rotates, the angle between the vertical shaft 6 and the base 1 changes. In actual use, the child's upper body is supported on the body plate 3 by the hands, and then the rotation direction of the vertical shaft 6 changes to cause the body plate 3 to repeatedly deflect in the vertical direction, so that the child's back is bent and the respiratory tract is facing downward. The body position adjustment helps to utilize the effect of gravity to make it easier for sputum to move from the lungs and bronchi to the trachea, thereby promoting expectoration.

[0041] At the same time, when the angle between the body plate 3 and the base 1 gradually changes, the sputum in the child's airway can be sucked into the intubation tube through the negative pressure cylinder 28 under the drive of the negative suction component to assist the child in expelling the sputum, and, through the coordinated use of the inter-patting component, the arc-shaped elastic patting seat 19 can be driven to pat the child's back reciprocally to simulate the manual back-tapping technique for expectoration. By patting the child's back, the sputum attached to the airway wall can be loosened, making it easier to be coughed out or discharged through the suction tube.

[0042] It should be noted that, in actual use, the movement stroke of the arc-shaped elastic seat 19 when it moves toward the body plate 3 is fixed. Therefore, the initial distance between the arc-shaped elastic seat 19 and the upper surface of the body plate 3 can be changed to ensure that the arc-shaped elastic seat 19 can hit the child's back without causing discomfort to the child due to excessive hitting.

[0043] Furthermore, when the body plate 3 deflects in the vertical direction, the pushing assembly can slightly push the child's lower jaw to promote a slight synchronous lift of the child, thereby combining with the change in the child's body position, and the child's respiratory tract remains open to promote the discharge of sputum.

[0044] At the same time, during actual use, multiple sets of positioning worm gears 5 can be fixedly set on the base 1 through the axis seat 4, and multiple sets of swing worm gears 8 meshing with the positioning worm gears 5 can be set on the body plate 3, and the multiple sets of swing worm gears 8 are connected by transmission to ensure the stability of the body plate 3 during the swinging process.

[0045] In one of the more preferred embodiments, the negative suction assembly includes a co-located worm 9 fixedly sleeved on the vertical shaft 6, the co-located worm 9 is meshingly connected with a side worm wheel 10, a mortise plate fixedly connected to the lower surface of the body plate 3, and the side worm wheel 10 is fixedly rotated on the mortise plate;

[0046] The side worm wheel 10 is coaxially fixed with a torsion gear 11, and the torsion gear 11 is meshed with a rack 12. A sliding frame 13 is fixedly connected to the lower surface of the body plate 3, and a groove body 1 is provided on the sliding frame 13 for the rack 12 to be slidably connected.

[0047] The rack 12 is fixedly connected to one end of the negative pressure cylinder 28 with a sealing plate 27, and the outer peripheral surface of the sealing plate 27 is in sliding contact with the inner wall of the negative pressure cylinder 28. The negative pressure cylinder 28 includes an integrally formed air inlet channel 29 and an air outlet channel. The air inlet channel 29 is fixedly connected to the cannula, and the negative pressure cylinder 28 is fixedly connected to the body plate 3.

[0048] like Figure 2 and Figure 8As shown, when the vertical shaft 6 rotates to adjust the orientation of the body plate 3, it can synchronously drive the coaxial worm 9 fixedly arranged on the vertical shaft 6 to rotate, and then drive the side worm wheel 10 meshed with the coaxial worm 9 to rotate on the body plate 3. Among them, the swing gear 11 is coaxially fixed with the side worm wheel 10 and rotates synchronously with the side worm wheel 10. Therefore, when the side worm wheel 10 rotates, it can drive the rack 12 to slide along the surface of the body plate 3.

[0049] At the same time, when the angle between the body plate 3 and the leg 2 becomes smaller, the rack 12 can move away from the negative pressure cylinder 28, and then promote the sealing plate 27 on the rack 12 to gradually move away from the negative pressure cylinder 28. Thus, under the movement state of the sealing plate 27, negative pressure suction is generated in the negative pressure cylinder 28. This suction is transmitted to the intubation tube through the air intake passage 29, and then promotes the sputum in the child's respiratory tract to be sucked into the intubation tube under this negative pressure.

[0050] It should be noted that during actual use, the air intake passage 29 is detachably connected to the intubation tube. The intubation tube can be a disposable product. At the same time, a sputum filtering net can be arranged at the air intake passage 29 to prevent sputum from entering the negative pressure cylinder 28. At the same time, a set of one-way valves are respectively arranged on the air intake passage 29 and the air outlet passage, and the valve ports of the two sets of one-way valves are in opposite directions. When the sealing plate 27 moves away from the negative pressure cylinder 28, it can drive the negative pressure suction at the air intake passage 29 to be transmitted to the intubation tube, and at the same time prevent the sputum already sucked out in the intubation tube from being pushed back into the respiratory tract again.

[0051] Based on the negative suction component embodiment, the intermittent percussion component includes an L-shaped fixed extension rod 17 arranged on one side of the body plate 3 and reciprocating perpendicular to the upper surface of the body plate 3. A rectangular seat 18 is fixedly connected to the body plate 3, and a rectangular through groove for the L-shaped fixed extension rod 17 to slide through is opened on the rectangular seat 18;

[0052] The arc-shaped elastic percussion seat 19 is fixedly connected to the L-shaped fixed extension rod 17, and the arc-shaped elastic percussion seat 19 faces the upper surface of the body plate 3.

[0053] The side worm wheel 10 is coaxially fixed with a special-shaped disc 14. One end of the L-shaped fixed extension rod 17 facing the special-shaped disc 14 is fixedly connected with a limit pin 15, and a flower-shaped groove 16 for the limit pin 15 to slide and connect is opened on the special-shaped disc 14.

[0054] Such as Figure 1 、 Figure 4 and Figure 5As shown, when the side worm gear 10 rotates, it can drive the special-shaped disk 14 fixed coaxially therewith to rotate synchronously, wherein the limit pin 15 fixedly arranged on the L-shaped fixed extension rod 17 is slidably connected to the special-shaped disk 14 through the flower-shaped groove 16, and then when the special-shaped disk 14 rotates, the relative positions of the limit pin 15 and the flower-shaped groove 16 can be changed. At the same time, the L-shaped fixed extension rod 17 slides through the rectangular seat 18, and the rectangular seat 18 is fixedly arranged on the body plate 3, and then when the special-shaped disk 14 rotates, the arc-shaped elastic seat 19 fixedly arranged on the L-shaped fixed extension rod 17 can move close to or away from the upper surface of the body plate 3.

[0055] It should be noted that, in actual use, in order to take into account the differences in body shape and the strength of slapping that different children can withstand, the L-shaped fixed extension rod 17 can be a telescopic structure to adjust the distance between the arc-shaped elastic slap seat 19 and the upper surface of the body plate 3 in the initial state, thereby ensuring the slapping effect while avoiding the discomfort caused by excessive slapping. At the same time, vibration can be generated by slapping the back to loosen the sputum attached to the airway wall, reduce the adhesion of the sputum to the airway wall, and make it easier to be coughed out or discharged through the negative suction component.

[0056] Based on the embodiment of the inter-beat assembly, the push assembly includes a transverse rod 26 fixedly connected to the body plate 3, the transverse rod 26 is provided with a longitudinal push rod 25 that reciprocates along the laying direction of the body plate 3, and the transverse rod 26 is provided with a groove body 2 for the longitudinal push rod 25 to be slidably connected;

[0057] The longitudinal push rod 25 is provided with a jaw plate 30 that contacts with the child's lower jaw. The jaw plate 30 is detachably connected to the longitudinal push rod 25 , and a locking bolt that contacts with the longitudinal push rod 25 is threadedly connected to the jaw plate 30 .

[0058] The pushing assembly also includes a transverse shaft that rotates on the engagement plate, a swing rod 23 is fixedly sleeved on the transverse shaft, and a connecting rod 24 is fixedly rotated on one end of the swing rod 23 away from the transverse shaft, and the connecting rod 24 is fixedly rotated on the longitudinal push rod 25 on one end away from the swing rod 23.

[0059] like Figure 1 , Figure 2 and Figure 8As shown, when the horizontal axis reciprocally rotates by a certain angle on the body plate 3, it can drive the swing rod 23 fixedly arranged coaxially thereon to rotate synchronously. Among them, when the swing rod 23 swings towards the longitudinal push rod 25, it can drive the longitudinal push rod 25 to move upward above the body plate 3 through the connecting rod 24 arranged between the two. During actual use, the relative positions of the jaw position plate 30 and the longitudinal push rod 25 can be adjusted by the locking bolt, so as to drive the jaw position plate 30 to abut against the lower jaw position of the child, and promote the child's head to tilt slightly upward during the upward movement of the jaw position plate 30, so as to help the child keep the respiratory tract open, effectively relieve upper airway obstruction, promote smooth breathing, and can increase the breathing depth and coughing force, stimulate the cough reflex, and help sputum discharge from the trachea and bronchi.

[0060] On the basis of the embodiment of the pushing component, a longitudinal swing seat 22 is also fixedly sleeved on the horizontal axis. A positioning pin 21 is fixedly connected to one side surface of the swing gear 11 facing the longitudinal swing seat 22, and a positioning groove 222 for the positioning pin 21 to slide and connect is opened on the longitudinal swing seat 22.

[0061] A notch blocking ring 20 is fixedly connected to one side surface of the swing gear 11 facing the positioning pin 21. The longitudinal swing seat 22 includes two integrally formed side groove parts 221. The two side groove parts 221 are respectively located on both sides of the positioning groove 222, and both side groove parts 221 are in sliding contact with the notch blocking ring 20.

[0062] As Figure 2 、 Figure 6 and Figure 7 As shown, when the side-position worm gear 10 rotates, it can drive the swing gear 11 coaxially arranged with it to rotate synchronously. When the included angle between the body plate 3 and the base 1 initially changes, the positioning pin 21 fixedly arranged on the swing gear 11 can enter the positioning groove 222, and drive the longitudinal swing seat 22 to rotate through the positioning groove 222. The longitudinal swing seat 22 is coaxially fixed on the horizontal axis, so as to drive the swing rod 23 to rotate by a certain angle through the longitudinal swing seat 22. Furthermore, when the body plate 3 initially swings, the pushing component can be driven to operate to keep the child's respiratory tract open.

[0063] At the same time, when the positioning pin 21 disengages from the positioning groove 222, the longitudinal swing seat 22 and the horizontal axis will no longer rotate. At this time, the notch blocking ring 20 fixedly arranged on the swing gear 11 corresponds to one group of side groove parts 221, and then the outer peripheral surface of the notch blocking ring 20 is in sliding contact with this group of side groove parts 221 as the swing gear 11 rotates, so as to limit the arbitrary rotation of the longitudinal swing seat 22 under the action of external force through the notch blocking ring 20, so as to ensure that the jaw position plate 30 can always slightly lift the lower jaw position of the child, so as to always keep the airway open during subsequent body position changes.

[0064] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
