[0059] Example 1

[0060] Please see Figure 1-2 Specifically, in the embodiment of this closed suction device, the closed suction device provided in this application specifically includes a suction tube 1, a protective sleeve 2, a connector 3, a camera 4, and a negative pressure connector 5. The suction tube 1 has a suction chamber 11 and a viewing chamber 12 inside, both arranged along the length of the suction tube 1. The viewing chamber 12 is independent of the suction chamber 11. One end of the suction tube 1 has a suction hole 13 that is connected to the suction chamber 11. The protective sleeve 2 is fitted around the suction tube 1 to protect it. The end of the sleeve 2 away from the suction hole 13 is fixedly connected to the other end of the suction tube 1. The end of the protective sleeve 2 near the suction hole 13 is provided with a connecting end. The connector 3 is detachably connected to the connecting end. The connector 3 has a connecting channel. The inner cavity of the protective sleeve 2 is connected to the connecting channel of the connector 3. The camera 4 is fixed in the visual cavity 12 at the end near the suction hole 13. The camera 4 is connected to an external display terminal. The negative pressure connector 5 is fixed in the other end of the suction tube 1. The negative pressure connector 5 has a negative pressure channel. The negative pressure channel is connected to the suction cavity 11.

[0061] Specifically, this utility model embodiment provides a closed suction device, including a suction tube 1, a protective sleeve 2, a connector 3, a camera 4, and a negative pressure connector 5. The suction tube 1 has a suction chamber 11 and a viewing chamber 12 inside, both arranged side-by-side along the length of the suction tube 1. The viewing chamber 12 is independent of the suction chamber 11 and not connected to it. One end of the suction tube 1 has a suction hole 13 that is connected to the suction chamber 11. The protective sleeve 2 is fitted around the suction tube 1. The protective sleeve 2, located away from the suction hole 13, is fixedly connected to the other end of the suction tube 1. A connecting end is provided at the end of the protective sleeve 2 closest to the suction hole 13. The connector 3 is detachably connected to the connecting end and has a connecting channel. The inner cavity of the protective sleeve 2 communicates with the connecting channel of the connector 3. A camera 4 is fixed inside the viewing cavity 12 at the end closest to the suction hole 13 and is communicatively connected to an external display terminal. A negative pressure connector 5 is fixed to the other end of the suction tube 1 and has a negative pressure channel that communicates with the suction cavity 11. This embodiment of the application, by setting up a viewing cavity 12 and fixing the camera 4 at the end of the viewing cavity 12, allows observation of sputum in the patient's airway, tracheostomy tube, nasal passage, and oropharynx after the end is inserted into the patient's airway. This avoids blind suction, improves suction efficiency and accuracy, achieves precise suction, and reduces patient discomfort. By making the connector 3 detachably connected to the protective sleeve 2, the airtightness of the suction tube 1 can be ensured, and it can be adapted to different patient needs, such as ordinary patients who do not need to wear a ventilator and patients who need to wear a ventilator.

[0062] In one possible implementation, the end of the negative pressure connector 5 away from the suction tube 1 is connected to an external negative pressure suction tube to provide negative pressure suction to the suction tube 1 through the external negative pressure suction tube.

[0063] In one possible implementation, a negative pressure control valve 6 is provided at the connection point between the negative pressure connector 5 and the suction tube 1. The negative pressure control valve 6 is communicatively connected to an external display terminal. Opening and closing commands can be sent to the negative pressure control valve 6 through the external display terminal to control the start and stop of the negative pressure control valve 6, thereby facilitating the operation of negative pressure suction.

[0064] In one possible implementation, a scale mark 14 is provided on the outer wall of the suction tube 1 to facilitate observation of the insertion depth of the suction tube 1, avoid excessive insertion which may cause symptoms such as coughing, shortness of breath, and respiratory discomfort in the patient, and reduce the patient's suffering.

[0065] In one possible implementation, a switch 7 is provided on the negative pressure connector 5, and the switch 7 is electrically connected to the camera 4. By pressing the switch 7, the camera 4 is turned on to visualize the suctioning process.

[0066] In one possible implementation, such as Figure 1-2 As shown, the connector 3 includes a three-way connector 31, an endotracheal bronchus 32, a breathing bronchus 33, a humidification fluid bronchus 34, and a flushing assembly 35. One end of the endotracheal bronchus 32 is fixedly connected to the first end of the three-way connector 31; one end of the breathing bronchus 33 is fixedly connected to the second end of the three-way connector; one end of the humidification fluid bronchus 34 is disposed on the side wall of the three-way connector 31 and is connected to the three-way connector 31; one end of the flushing assembly 35 is fixedly connected to the third end of the three-way connector 31, and the other end of the flushing assembly 35 is detachably connected to the connection end of the protective sleeve.

[0067] Furthermore, the flushing assembly 35 includes a two-way connecting pipe 351, a knob valve 352, and a flushing fluid branch pipe 353. One end of the two-way connecting pipe 351 is detachably connected to the connecting end of the protective sleeve. The knob valve 352 is located between the other end of the two-way connecting pipe 351 and the third end of the three-way connecting pipe 31, and the knob valve 352 controls the opening and closing between the two-way connecting pipe 351 and the three-way connecting pipe 31. The flushing fluid branch pipe 353 is located on the side wall of the two-way connecting pipe 351 and is connected to the two-way connecting pipe 351.

[0068] For ordinary patients who do not need to wear a ventilator, the connector 3 can be detached during actual use. At this time, the switch 7 of the camera 4 can be pressed, and the suction tube 1 can be extended from the connector end of the protective cover 2 to be inserted into the patient's airway for visual suction.

[0069] For patients who need to wear a ventilator, such as Figure 2 As shown, in actual use, the endotracheal bronchus 32 can be connected to an external endotracheal tube, and the breathing bronchus 33 can be connected to an external ventilator. At this time, the suction tube 1 is extended from the connecting end of the protective sleeve 2 and the connecting head 3 into the patient's airway. The depth of insertion into the airway can be observed through the scale on the suction tube 1, and the position of the sputum in the airway can be observed through the camera 4 to adjust the position of the suction tube 1 accordingly. When the sputum is too viscous and difficult to suction, humidifying fluid (such as normal saline) can be injected into the airway through the humidifying fluid bronchus 34 to improve the suction efficiency of the sputum. After suctioning, the suction tube 1 is returned to the two-way connecting tube 351. At this time, the knob valve 352 can be closed to completely isolate the channel between the three-way connecting tube 31 and the two-way connecting tube 351 to prevent the flushing fluid from entering the patient's airway. At this time, the flushing fluid can be injected through the flushing fluid bronchus 353. The flushing fluid enters the suction tube 1 through the suction hole 13 of the suction tube 1 to flush the inside of the suction tube 1.

[0070] It is understood that the connecting end of the protective sleeve 2 near the suction hole 13 can be a valve. When the valve is open, the suction tube 1 can extend from the valve opening to the outside of the protective sleeve 2 and then be inserted into the airway for suctioning. The valve and the connector 3 are detachably connected, specifically by a threaded connection to ensure a tight seal. At this time, the suction tube 1 can extend from the valve opening and the connecting channel of the connector 3.

[0071] In one possible implementation, there are two suction holes 13, which are spaced apart at one end of the suction tube 1. One suction hole 13 is located at the end of one end of the suction tube 1, and the other suction hole 13 is located on the side wall of one end of the suction tube 1.

[0072] Specifically, by setting one suction hole 13 at the end of the suction tube 1 and another suction hole 13 on the side wall of the suction tube 1, the suction efficiency of the suction tube 1 can be improved.

[0073] In one possible implementation, the other end of the tracheal bronchus 32 is connected to an external endotracheal tube, and the other end of the breathing bronchus 33 is connected to an external ventilator.

[0074] In one possible implementation, the other end of the humidifying fluid branch pipe 34 is connected to a first sealing plug 342 via a first connector 341; the other end of the flushing fluid branch pipe 353 is connected to a second sealing plug via a second connector.

[0075] Specifically, sealing plugs are installed to prevent dust and impurities from entering the humidifying fluid branch pipe 34 and the flushing fluid branch pipe 353 when they are not in use, thereby improving airtightness.

[0076] It should be noted that in this application, the suction chamber and the visual chamber are independent of each other, that is, they are not connected to each other. The tracheal bronchus, the breathing bronchus, the three-way connecting tube and the humidification fluid bronchus are connected. The knob valve is used to control the opening and closing of the three-way connecting tube and the two-way connecting tube. That is, when the knob valve is closed, neither gas nor liquid flows between the three-way connecting tube and the two-way connecting tube. When the knob valve is open, the suction tube can pass through the knob valve.

[0077] It should be noted that the structures, proportions, sizes, etc., illustrated in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of this invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of this invention, should still fall within the scope of the disclosed technical content.
