Technical Field

[0001] The invention relates to the technical field of medical devices, in particular to a visual sputum suction tube. Background Art

[0002] Suction tubes are a common medical device used to help clear secretions from the patient's respiratory tract. Traditional suction tubes usually do not have a visualization function, and doctors cannot intuitively see the location and state of the sputum during operation, which may lead to low suction efficiency and even damage to the patient's respiratory tract.

[0003] Suction tubes are usually disposable consumables. Although the prior art, such as CN111012994A, discloses a visual suction tube, the camera and the suction tube cannot be disassembled, resulting in the high cost of the suction tube as a whole, making it difficult to popularize. Suction tubes with detachable cameras require a certain amount of time to install the camera on the suction tube before suctioning. Patients with phlegm stuck in the respiratory tract usually require quick response and treatment.

[0004] Therefore, there is a need for a visual sputum suction tube that can be used for emergency treatment of patients and has low manufacturing cost. Summary of the invention

[0005] The technical problem to be solved by the present invention is: in view of the shortcomings of the prior art, a visual sputum suction tube is proposed. The present invention can be used as an ordinary sputum suction tube to quickly suction sputum from patients. When the suction is not smooth and it is difficult to find the location of sputum, the camera accessory can be quickly inserted to perform sputum suction under visual conditions. The technical solution provided by the present invention is as follows:

[0006] A visual sputum suction tube, comprising a tube body and a tube seat, wherein the tube body is provided with a sputum suction channel, a camera placement portion is provided at the end of the tube body, and a sputum suction hole is provided on the tube body near the camera placement portion;

[0009] As an improvement, a fixing ring is provided outside the one-way valve, and an arc-shaped valve is provided inside the fixing ring. The number of the arc-shaped valves is three and they are arranged in a circumferential array inside the fixing ring. The valve is fixedly connected to the fixing ring at the outer position, and a bending portion bent toward the end of the tube body is provided near the center position;

[0010] During suction, the three arc-shaped valves are pressed toward the center of the fixing ring under the action of air pressure and close the accommodating cavity and the sputum suction channel.

[0011] As an improvement, the top of the rotary cover is provided with an opening, an elastic sealing pad is provided in the opening, and a through hole is provided in the middle of the elastic sealing pad;

[0012] A threaded interface is provided at the insertion end of the camera, and a connecting portion matching the threaded interface is provided at the bottom of the rotary cover.

[0036] Example 1

[0037] The present embodiment discloses a visual sputum suction tube, comprising a tube body 1 and a tube seat 2. A sputum suction channel 11 is provided in the tube body 1. A camera placement portion 3 is provided at the end of the tube body 1. A sputum suction hole 12 is provided near the camera placement portion 3 in the tube body 1.

[0038] The camera placement portion 3 is provided with a receiving cavity 31 for placing the camera, the receiving cavity 31 is communicated with the sputum suction channel 11 , and a one-way valve 4 is provided between the receiving cavity 31 and the sputum suction channel 11 .

[0039] A fixing ring 41 is provided outside the one-way valve 4, and an arc-shaped valve 42 is provided inside the fixing ring 41. There are three arc-shaped valves 42 and they are arranged in a circular array inside the fixing ring 41. The arc-shaped valve 42 is fixedly connected to the fixing ring 41 at the outer position, and a bending portion 43 bent toward the end of the tube body 1 is provided near the center.

[0040] When suction is performed, the three arc-shaped valves 42 are pressed toward the center of the fixing ring 41 under the action of air pressure and close the accommodating cavity 31 and the sputum suction channel 11. In addition, the two ends of the bent portion 43 of the arc-shaped valve 42 are also fixed on the fixing ring 41, thereby ensuring that the arc-shaped valve 42 will not bend back and can always remain in a closed state under negative pressure suction.

[0041] When the camera needs to be inserted, since the arc-shaped valve 42 is made of a flexible material, such as silicone, the camera can push open the arc-shaped valve 42 and directly enter the accommodating cavity 31 .

[0042] The end of the tube base 2 is provided with a camera insertion end 21, and a screw cap 5 is provided at the camera insertion end 21. The tube base 2 is provided with a side branch pipe 22, and the end of the side branch pipe 22 is provided with a connector 23 connected to the negative pressure device, and the side branch pipe 22 is provided with a suction adjustment member 6.

[0043] The suction force adjustment member 6 is a second branch pipe 61 provided on the side branch pipe 22, and a plug 62 is provided at the end of the second branch pipe 61. After the connector 23 is connected to the negative pressure device of the hospital or the negative pressure pipe beside the bed, the plug 62 is opened, and the airflow is directly sucked from the second branch pipe 61, and no negative pressure is generated in the pipe body 1. After the plug 52 is plugged, negative pressure can be formed in the pipe body 1 to perform sputum suction operation.

[0044] An opening 51 is provided at the top of the rotary cover 5, an elastic sealing pad 52 is provided in the opening 51, and a through hole 53 is provided in the middle of the elastic sealing pad 52. The suction force adjustment member 6 is provided near the camera insertion end 21, and the plug 62 is flush with the rotary cover 5. When the camera is not inserted, the through hole 53 can be pressed by the thumb to avoid air leakage from the through hole 53 during the suction process, so as to improve the suction force. After the camera is inserted, the through hole 53 can be pressed tightly against the connection line of the camera to complete the sealing.

[0045] A threaded interface 24 is provided at the camera insertion end 21 , and a connecting portion 54 matching with the threaded interface 24 is provided at the bottom of the rotary cover 5 .

[0046] This embodiment also discloses a camera accessory for a visual sputum suction tube, comprising a connecting line 7 and a camera unit 8. An insertion seat 71 is provided at the end of the connecting line 7, and the connecting line 7 is detachably connected to the camera unit 8 through the insertion seat 71.

[0047] An insertion hole 72 is provided at the insertion seat 71, and an insertion bolt 81 is provided at the rear of the camera unit 8. A fill light 82 and a micro camera 83 are provided at the front end of the camera unit 8; three connection points 84 are provided at the insertion bolt 81, and the three connection points 84 are respectively connected to the positive electrode, the negative electrode and the data transmission line to supply power to the fill light 82 and the micro camera 83 and to transmit data. Electrodes corresponding to the three connection points 84 are provided in the insertion hole 72.

[0048] The diameter of the connecting line 7 is larger than the inner diameter of the through hole 53 . After the camera is inserted into the sputum suction tube through the through hole 53 , the elastic force of the elastic sealing pad 52 keeps the connection in a sealed state.

[0049] This solution can be used as an ordinary sputum suction tube for emergency sputum suction operation, but when sputum suction encounters difficulties and it is difficult to find the location of sputum, the screw cap 5 can be unscrewed, the connecting line 7 can be inserted from the through hole 53, and then the insertion plug 81 can be inserted into the insertion hole 72. Then the camera part 8 and the connecting line 7 are sent into the sputum suction channel 11. The arc valve 42 is made of flexible material. Under normal suction state, the arc valve 42 can effectively close the sputum suction channel 11. After penetrating the camera part 8, the camera part 8 can push the arc valve 42 to reach the position of the accommodating cavity 31, so as to perform subsequent visualized sputum suction operation. After the camera part 8 enters the accommodating cavity 31, the camera part 8 can block the accommodating cavity 31, and the arc valve 42 is tightly attached to the connecting line under the action of negative pressure suction and its own elastic force, and can still maintain good sealing performance.

[0050] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
