Technical Field

[0001] The utility model relates to the technical field of sputum suction tubes, in particular to a closed sputum suction tube with anti - aspiration function. Background Technique

[0002] Sputum suction is one of the most common and important operations in nursing work. Its purpose is to use the negative pressure to suck out the sputum and aspirated substances in the trachea through a closed sputum suction tube to keep the respiratory tract unobstructed. The closed sputum suction can maintain mechanical ventilation and ensure the relative stability of the intrapulmonary pressure before and after sputum suction.

[0003] After retrieval, the utility model patent with the Chinese patent publication number CN215690348U discloses a closed sputum suction tube with anti - aspiration function, which includes a sputum suction tube body, a flushing tube, a duck - bill valve and a transparent film sleeve. A negative - pressure connector is installed at the bottom end of the sputum suction tube body, a sputum suction tube connector is installed at the top end of the sputum suction tube body, the transparent film sleeve is installed around the sputum suction tube body, a connecting tube is arranged at the top end of the sputum suction tube connector, and a trachea connector is installed at the top end of the connecting tube. The beneficial effects are as follows: through the design of the flushing tube, the transparent film sleeve and the duck - bill valve, the sputum suction tube can always be in a closed space before and after use, effectively avoiding the pollution of the sputum suction tube during use, enabling the sputum suction tube to be reused multiple times, and being able to flush the sputum suction tube in time after use. At the same time, through the check - valve function of the duck - bill valve, the backflow of water in the sputum suction tube into the trachea is effectively avoided, greatly improving the flushing efficiency and the safety of use of the sputum suction tube.

[0004] After retrieval, the above - mentioned patent solves the problem of facilitating the flushing of the sputum suction tube, but lacks the collection, observation and treatment of the sputum drawn from the patient's body, resulting in that the operator can only make a rough calculation and cannot ensure the accuracy of measurement.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0022] Refer to Figures 1-3, A closed suction catheter with anti - aspiration function, including a suction catheter 1 and a collection box 11. The suction catheter 1 is rotatably connected to a sphere 2. A cavity 3 is arranged inside the sphere 2. Notches 4 are symmetrically arranged on the side wall of the sphere 2. A through - hole 5 is arranged on the side wall of the sphere 2. Both the notch 4 and the through - hole 5 are communicated with the cavity 3. The upper end of the suction catheter 1 penetrates and is fixedly connected to a flushing tube 9. A connecting hose 10 is communicated between the suction catheter 1 and the collection box 11. A cover plate 12 is rotatably connected to the side of the collection box 11 by threads. A connecting pipe 13 penetrates and is fixedly connected to the side wall of the collection box 11. The end of the suction catheter 1 is snap - connected to a connector 14. A torsion block 19 is rotatably connected to the side wall of the connector 14. A trachea 21 penetrates and is fixedly connected inside the connector 14. A scale is arranged on the side wall of the collection box 11. The operator snap - connects the connector 14 to the suction catheter 1, so that the trachea 21 is communicated with the inside of the suction catheter 1, connects the negative pressure device to the connecting pipe 13, and then connects the external joint to the flushing tube 9. At the same time, the sphere 2 is rotated so that the two notches 4 are level. At this time, the through - hole 5 is closed. Then the negative pressure device is started, and the sputum in the patient's body is sucked out through the trachea 21, the suction catheter 1 and the connecting hose 10 and is drawn into the collection box 11.

[0023] A knob 6 is rotatably connected through the side wall of the suction catheter 1, and the end of the knob 6 is fixedly connected to the side wall of the sphere 2. The operator manually rotates the knob 6 to make the sphere 2 rotate.

[0024] Limiting grooves 8 are arranged on the inner walls at both ends of the suction catheter 1. A limiting block 7 is fixedly connected to the side wall of the sphere 2. The limiting groove 8 and the limiting block 7 cooperate with each other. Through the cooperation between the limiting groove 8 and the limiting block 7, the sphere 2 can be limited, so as to prevent the sphere 2 from being rotated in the wrong direction, resulting in the patient accidentally inhaling the cleaning liquid into the body.

[0025] A plurality of clamping blocks 15 are slidably connected inside the connector 14. A connecting rope 20 is fixedly connected between the end of the clamping block 15 and the inner wall of the torsion block 19. A convex block 16 is arranged at the end of the suction catheter 1. There are a plurality of convex blocks 16, and the plurality of convex blocks 16 are annularly arranged around the center point of the suction catheter 1. The clamping block 15 cooperates with the convex block 16. The lower end of the clamping block 15 is arc - shaped, and the end of the convex block 16 is inclined. By rotating the torsion block 19 to rotate and wind the connecting rope 20, the clamping block 15 contracts and disengages from the convex block 16.

[0026] A slider 17 is fixedly connected to the side wall of the clamping block 15. A spring 18 is fixedly connected between the slider 17 and the inside of the connector 14. When the operator releases the torsion block 19, the clamping block 15 automatically resets due to the elasticity of the spring 18.

[0027] A sealing gasket 22 is fixedly connected to the side wall of the connector 14. The side wall of the sealing gasket 22 fits with the inner wall of the suction catheter 1. By installing the sealing gasket 22, it can prevent side leakage when sucking sputum from the patient.

[0028] In the present utility model, an operator slides a plurality of bumps 16 into the inside of the connector 14, so that the latch 15 engages with the bumps 16. At this time, the trachea 21 is in communication with the inside of the sputum suction tube 1, and at the same time, the sealing gasket 22 fits against the inner wall of the sputum suction tube 1. When it is necessary to separate the connector 14 from the sputum suction tube 1, the operator rotates the torsion block 19 to wind the connecting rope 20, so that the latch 15 contracts and disengages from the bumps 16 to separate the two.

[0029] Connect the negative pressure device to the connecting pipe 13, and rotate the knob 6 so that the two notches 4 inside the sphere 2 are level. At this time, the through hole 5 is closed, and thus the negative pressure device is started. The sputum in the patient's body is sucked into the inside of the collection box 11 through the trachea 21, the sputum suction tube 1 and the connecting hose 10.

[0030] When it is necessary to clean the inside of the sputum suction tube 1, the operator rotates the knob 6 so that the through hole 5 is located below the flushing tube 9. At this time, one of the notches 4 fits against the inner wall of the sputum suction tube 1 and closes. At the same time, through the cooperation between the limit groove 8 and the limit block 7, the sphere 2 can be limited to prevent the sphere 2 from being misaligned, which may cause the patient to accidentally inhale the cleaning solution into the body. The cleaning solution is introduced into the cavity 3 through the through hole 5, and then the cleaning solution is discharged through the other notch 4 to clean the inside of the sputum suction tube 1.

[0031] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
