Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to a sputum suction and drainage tube flushing device. Background Art

[0002] Suctioning is a technique that uses negative pressure to remove secretions from the respiratory tract through a catheter, oral cavity, nasal cavity, or artificial airway. The goal of suctioning is to maintain airway patency and prevent complications such as aspiration pneumonia, atelectasis, and asphyxiation.

[0003] Currently, negative pressure suction is performed clinically by connecting a suction tube to a negative pressure device via a drainage tube. The tube is then inserted into the patient's respiratory tract through the mouth, nose, or artificial airway to suction the sputum. Because suction tubes are inserted into the body and are typically disposable, they must be disposed of as medical waste after suctioning. Drainage tubes, on the other hand, do not need to be inserted into the body and are not typically disposable clinically. Instead, they are rinsed and disinfected after each suctioning session so they can be reused.

[0004] The current clinical method of flushing the drainage tube is to separate the drainage tube from the suction tube, insert the tube connector of the drainage tube into a bottle containing a flushing solution, and then tilt the bottle sideways to immerse the tube connector in the flushing solution. Under the suction action of the negative pressure device, the flushing solution enters the drainage tube through the tube connector to flush the drainage tube. This flushing method has at least the following disadvantages: 1) When the tube connector of the used drainage tube is inserted into the bottle through the bottle mouth, it is easy to contaminate the bottle mouth, and when the tube connector of the drainage tube is immersed in the flushing solution, it is easy to cause contamination of the entire bottle of flushing solution; 2) The flushing solution directly enters the tube cavity through the tube connector, which is not easy to flush the tube wall, making it easy for sputum to remain on the tube wall. The sputum on the tube wall is not easy to flush clean, which is a common problem of this current flushing method.

[0005] Therefore, it is necessary to design a flushing device that will not contaminate the entire bottle of flushing fluid and can thoroughly clean the tube wall of the drainage tube. Utility Model Content

[0016] A support column is provided at the center of the liquid outlet pipe;

[0017] There are multiple guide plates, each of which is spiral and evenly arranged inside the liquid outlet pipe along the circumferential direction. One end of the guide plate is fixedly connected to the support column, and the other end is fixedly connected to the inner wall of the liquid outlet pipe 5.

[0018] Furthermore, it also includes:

[0021] Furthermore, it also includes:

[0022] The air-permeable cover can be opened and closed to cover the liquid filling port.

[0023] Furthermore, the control valve is a one-way throttle valve.

[0041] The present application will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0042] This embodiment provides a sputum suction and drainage tube flushing device, such as Figure 1-4 As shown, it includes a liquid storage tank 1, a T-tube 3, a control valve 2, an air inlet pipe 4 and a liquid outlet pipe 5; the liquid storage tank 1 is used to contain flushing liquid, and is provided with a liquid filling port 11 on the top and a first liquid outlet 12 on the bottom; the T-tube 3 includes a horizontal pipe 31 and a vertical pipe 32 arranged in the middle of the horizontal pipe 31, and the pipe mouth at the upper end of the vertical pipe 32 is fixedly connected to the first liquid outlet 12; the control valve 2 is installed on the vertical pipe 32, and is used to control the on and off of the vertical pipe 32; the air inlet pipe 4 is connected with the pipe mouth on one side of the horizontal pipe 31; the liquid outlet pipe 5 is connected with the pipe mouth on the other side of the horizontal pipe 31, and the interior of the liquid outlet pipe 5 is provided with a diversion structure, which can make the flushing liquid flowing out of the liquid outlet pipe 5 spray outward in a spiral diffusion form; the liquid outlet pipe 5 is suitable for docking with the drainage pipe.

[0043] The suction drainage tube flushing device of this embodiment requires that the liquid outlet pipe 5 be docked and connected to the drainage tube to be flushed during the cleaning operation. For example, the free end of the liquid outlet pipe 5 can be inserted into the drainage tube and sealed to the drainage tube. When in use, first close the control valve 2, then pour the flushing liquid into the liquid storage tank 1 through the liquid filling port 11; dock the liquid outlet pipe 5 with the drainage tube, and then turn on the negative pressure device; open the control valve 2, so that the flushing liquid is sprayed into the drainage tube in a spiral diffusion form through the liquid outlet pipe 5 under the action of negative pressure; when the drainage tube is flushed, the control valve 2 can be closed first, and then the negative pressure device can be turned off, and finally the drainage tube can be removed from the liquid outlet pipe 5.

[0044] In this embodiment, the flushing liquid is contained in the liquid storage tank 1, which can be added on demand to avoid waste; the drainage tube is not in direct contact with the flushing liquid in the liquid storage tank 1, thereby preventing the drainage tube from contaminating unused flushing liquid; the diversion structure can make the flushing liquid flowing out of the liquid outlet pipe 5 spray outward in a spiral diffusion form, so that the flushing liquid can flush the wall of the drainage tube.

[0045] The sputum suction drainage tube flushing device of this embodiment further comprises a plurality of diversion channels 51 formed inside the liquid outlet pipe 5, wherein the plurality of diversion channels 51 extend spirally inside the liquid outlet pipe 5 along the length direction of the liquid outlet pipe 5 and form a corresponding second liquid outlet 50 at the free end of the liquid outlet pipe 5.

[0046] In this embodiment, the number of guide channels 51 can be set as needed, for example, it can be two or three or four or five, etc. When the flushing liquid in the horizontal tube 31 flows through the spirally extended guide channel 51, the flow direction of the flushing liquid will change from a direction parallel to the tube wall of the horizontal tube 31 to a direction forming a certain angle with the tube wall of the horizontal tube 31. Finally, the flushing liquid in multiple guide channels 51 converges at the second liquid outlet 50 and forms a spiral diffusion form, thereby flushing the tube wall of the drainage tube.

[0047] In the sputum suction and drainage tube flushing device of this embodiment, further, the second liquid outlets 50 are evenly distributed along the circumferential direction on the free end of the liquid outlet tube 5 .

[0048] The suction drainage tube flushing device of this embodiment has a guide structure which is a spiral guide member arranged inside the liquid outlet pipe 5, and the spiral guide member includes a support column 53 and a guide plate 55; the support column 53 is arranged at the central position inside the liquid outlet pipe 5; there are multiple guide plates 55, and the guide plates 55 are spiral-shaped and uniformly arranged inside the liquid outlet pipe 5 along the circumferential direction, and one end of the guide plate 55 is fixedly connected to the support column 53, and the other end is fixedly connected to the inner wall of the liquid outlet pipe 5.

[0049] In this embodiment, the number of guide plates 55 can be set as needed, for example, it can be two, three, four, or five, etc. After the flushing liquid in the horizontal tube 31 enters the liquid outlet pipe 5, the flushing liquid will be guided by the guide plates 55. The flow direction will change from a direction parallel to the tube wall of the horizontal tube 31 to a direction forming a certain angle with the tube wall of the horizontal tube 31, and finally converge at the second liquid outlet 50 and form a spiral diffusion form, thereby flushing the tube wall of the drainage tube.

[0050] The suction drainage tube flushing device of this embodiment further includes a base 6 and a bracket 7; the bracket 7 is fixedly mounted on the base 6, and the upper end is detachably connected to the bottom of the liquid storage tank 1, and the upper end of the bracket 7 is provided with a receiving cavity 71 for accommodating the control valve 2 and the T-tube 3.

[0051] The sputum suction and drainage tube flushing device of this embodiment further includes a breathable cover 8, which can be opened and closed to cover the liquid filling port 11, thereby preventing external pollutants from falling into the liquid storage tank.

[0052] In the sputum suction and drainage tube flushing device of this embodiment, further, the control valve 2 is a one-way throttle valve.

[0053] In this embodiment, the one-way throttle valve can regulate the flow rate of the flushing liquid by controlling the opening size, and on the other hand, it can prevent external pollutants from flowing back from the outlet of the one-way throttle valve into the liquid storage tank 1 and causing contamination of the flushing liquid.

[0054] The suction drainage tube flushing device of this embodiment further comprises the air inlet pipe 4 including a straight section 41 and a vertical section 42; one end of the straight section 41 is connected to the pipe opening on one side of the horizontal tube 31, and the other end extends horizontally in a direction away from the horizontal tube 31; the vertical section 42 is provided at the other end of the straight section 41 and extends upward in a vertical direction; the height of the opening at the free end of the vertical section 42 is higher than the height of the liquid filling port 11 of the liquid storage tank 1.

[0055] In this embodiment, the height of the opening of the free end of the vertical section 42 is higher than the height of the liquid filling port 11 of the liquid storage tank 1, which can prevent the flushing liquid from overflowing through the opening of the vertical section 42. For example, when the negative pressure device malfunctions and the suction force is insufficient to draw the flushing liquid into the drainage tube, or when the negative pressure device is turned off first after flushing but the control valve 2 is not closed, the flushing liquid will enter the air intake pipe 4 through the T-tube. In this case, if the height of the opening of the free end of the vertical section 42 is lower than the height of the liquid level in the liquid storage tank 1, the flushing liquid may overflow through the opening of the vertical section 42. However, if the opening of the free end of the vertical section 42 is set to be higher than the height of the liquid filling port 11 of the liquid storage tank 1, the flushing liquid can be prevented from overflowing from the opening of the vertical section 42.

[0056] In the sputum suction and drainage tube flushing device of this embodiment, further, the free end of the vertical section 42 is formed with an arc-shaped section 43 opening downward.

[0057] In this embodiment, a downwardly opening arc section 43 is provided at the free end of the vertical section 42 to prevent foreign matter from falling into the air inlet pipe 4, thereby contaminating or clogging the interior of the air inlet pipe 4 and affecting the flushing effect.

[0058] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of this innovative technical solution.
