[0005] ③ Three-way connector: connects the suction tube, ventilator circuit and artificial airway interface.

[0006] ④Flush port: used to connect physiological saline to clean the inside of the suction tube to prevent blockage.

[0007] For patients with tracheostomy tubes connected to mechanical ventilation, the traditional closed suction tube is too high and cannot be adjusted, which will cause the tracheostomy tube to tilt, affect the patient's fistula and compress the mucosa around the air bag, etc. In addition, when performing bronchoscopy, there is no operating hole for bronchoscopy, so it is necessary to change to an elbow threaded tube with an operating port. Therefore, it is necessary to develop a rotatable closed suction tube to make it more suitable for tracheostomy patients and facilitate bronchoscopy. Summary of the invention

[0008] The purpose of the present invention is to address the technical problems in the prior art that the closed sputum suction tube is too high for tracheotomy patients and cannot be adjusted after being connected to the mechanical ventilation equipment, which easily causes the tracheotomy tube to tilt and causes compression on the patient's fistula. The present invention provides a rotatable closed sputum suction tube, which is suitable for patients with mechanical ventilation. When doing bronchoscopy, it is only necessary to rotate the sputum suction tube to perform bronchoscopy through the operating port exposed on the top, and there is no need to change to an elbow threaded tube.

[0009] In order to achieve the above-mentioned purpose, the present invention provides a rotatable closed sputum suction tube, including a sputum suction tube assembly and a three-way joint connected to the sputum suction tube assembly, the sputum suction tube assembly includes a sputum suction tube and a thin film protective cover arranged outside the sputum suction tube, the three-way joint is provided with a tracheal intubation interface, a ventilator interface and a sputum suction tube interface, the sputum suction tube is connected to the sputum suction tube interface through a first set of sputum suction tube joints, and a part of the sputum suction tube is rotatably connected to the first set of sputum suction tube joints.

One end of the valve channel of the rotatable one-way valve is fixedly connected to the suction tube, and the pipeline of the suction tube is connected to the valve channel of the rotatable one-way valve.

[0011] Preferably, a bronchoscope insertion port is provided above the first sleeve joint of the suction tube, directly opposite to the rotatable one-way valve. The rotatable one-way valve is a sphere with a notch at one end and the same diameter as the first sleeve joint of the suction tube. The notch is located at the other end of the valve channel of the rotatable one-way valve.

[0012] Preferably, a bayonet is provided at the end of the first sleeve joint of the sputum suction tube, and the sputum suction tube is connected to the bayonet by means of a bayonet connection or a pin connection.

[0014] Preferably, the three-way connector is also provided with a drug inlet interface and a cleaning interface, and the drug inlet interface and the cleaning interface are located on opposite sides of the ventilator interface.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] (1) The present invention solves the problem that the suction tube is too high and cannot be adjusted for tracheotomy patients after being connected to the mechanical ventilation equipment by designing a rotatable closed suction tube. The rotatable design can adjust the position of the tube as needed to make it more suitable for the patient's tracheotomy tube without affecting the stability of the ventilator circuit, while reducing the problem of patient discomfort caused by inappropriate height and angle.

[0017] (2) Make the suction tube more in line with the actual needs of patients and improve the convenience of suction operation: by optimizing the height and angle design, avoid compression on the tracheostomy tube fistula and surrounding tissues, and improve the comfort and safety of patients; when suction is needed, the suction tube can be adjusted to the appropriate position by simple rotation, and can be reset after use, which not only reduces complex operating steps, but also ensures that the position of the equipment is reasonable and tidy when not in use; and avoids frequent disassembly or readjustment of the equipment, thereby improving the efficiency of medical operations and the safety of patients.

[0018] (3) Integrated function: The operating port can be rotated upward by adjusting the rotation, which not only supports daily suction operations, but also enables direct bronchoscopy operations, achieving seamless connection between suction and bronchoscopy. This design is based on the concept of reducing equipment switching and maintaining a sterile environment.

[0019] (4) Wide scope of application: The suction tube of the present invention is suitable for various tracheotomy patients and mechanical ventilation environments, can meet different clinical needs, and has good versatility; the suction tube not only improves the adaptability and functional integration of the equipment, but also greatly optimizes the operating experience, taking into account patient safety and operating efficiency, and has broad application prospects.

[0026] In order to make the present invention more clearly understood, preferred embodiments are described in detail below with reference to the accompanying drawings.

[0027] Example 1

[0028] This embodiment provides a rotatable closed sputum suction tube, such as Figures 1 to 5 As shown, it includes a sputum suction tube assembly 2, a first joint 1 and a second joint 3. The sputum suction tube assembly 2 includes a sputum suction tube 201. The first joint 1 is a three-way joint, and the second joint 3 is a joint for connecting a negative pressure device. One end of the sputum suction tube 201 passes through the interior of the three-way joint 1, and the other end passes through the interior of the second joint 3. A one-way rotating valve is provided on the three-way head. The sputum suction tube 201 is provided with a film protective sleeve 202 on the outer cover, and the two ends of the film protective sleeve 202 are detachably arranged at the ends of the first joint 1 and the second joint 3 through the sleeve joints that pass through the inside, and the film protective sleeve 202 and the sleeve joint are in close contact to form a closed space. Among them:

[0029] The first joint 1 is a T-shaped or substantially T-shaped three-way joint, one straight end of which is an endotracheal tube interface 101, the other end is a sputum suction tube interface 103, and the non-straight end is a ventilator interface 102. The three-way joint is also provided with a drug inlet interface 104 and a cleaning interface 105; the sputum suction tube 201 is connected to the sputum suction tube interface 103 in a detachable manner through the first sputum suction tube joint 203, and the sputum suction tube 201 is rotatably connected to the first sputum suction tube joint 203. Specifically, a bayonet 203a is provided at the end of the first sputum suction tube joint 203, and the sputum suction tube 201 is rotatably connected to the buckle 203a by snap connection or pin connection, and a small section of the sputum suction tube 201 can be fixed on a snap connection seat (not shown in the figure) that matches the shape of the buckle, and the snap connection seat is snapped on the buckle 203a or connected to the bayonet 203 by a pin (snap connection or pin connection is an existing connection method, not shown in the figure). By rotatably connecting with the first sleeve joint 203 of the sputum suction tube, the height position of the sputum suction tube 202 can be adjusted by rotation during the sputum suction operation, thereby avoiding compression of the tracheotomy tube fistula and surrounding tissues;

[0030] The first sleeve joint 203 of the sputum suction tube is also provided with a rotatable one-way valve 204. The material of the rotatable one-way valve 204 can be selected from medical silicone or rubber. The rotatable one-way valve 204 is fixedly connected to the sputum suction tube 201, and the sputum suction tube 201 pipeline is connected with the valve channel of the rotatable one-way valve 204. The first sleeve joint 203 of the sputum suction tube is provided with a bronchoscope insertion port 205 directly above the rotatable one-way valve 204. The rotatable one-way valve 204 is hemispherical or spherical with a notch. When the sputum suction operation is performed, the end with the notch is located in the horizontal direction. The diameter of the rotatable one-way valve 204 in the vertical direction is equivalent to the diameter of the first sleeve joint 203 of the suction tube, and because it is made of silicone or rubber, it can form a seal, which is conducive to suction operation in a closed space after connecting negative pressure; when bronchoscopy is required, the suction tube 201 is rotated, and the suction tube 201 drives the rotatable one-way valve 204 to rotate, so that its notch is rotated in the vertical direction to form a bronchoscope operation port, and the bronchoscope is inserted into the patient's airway through the bronchoscope insertion port 205 and the operation port exposed on the rotatable one-way valve 204 to observe the patient's airway condition.

[0031] The method of using the sputum suction tube of the present invention:

[0032] 1. Suctioning

[0033] Suction preparation: Make sure the closed suction tube is properly connected to the three-way connector between the patient's tracheostomy tube and the ventilator circuit. Check whether the suction tube is in the proper position and whether the rotatable part of the tube is flexible.

[0034] Suction tube adjustment: According to the patient's body position requirements, turn the suction tube to the angle and position required for suction.

[0035] Suction process: Turn on the negative pressure suction device, insert the suction tube into the artificial airway, and clear the secretions.

[0036] After the operation is completed, clean the suction tube by injecting clean water through the cleaning interface on the three-way connector, and reset the suction tube to the default position to ensure that it does not affect the patient's daily breathing.

[0037] 2. Bronchoscopy

[0038] Inspection preparation: Turn the suction tube so that the operating port of the rotatable one-way valve is in the vertical direction, facing the bronchoscope insertion port 205, and ensure that the equipment is clean and correctly connected to the tracheostomy tube and ventilator circuit.

[0039] Inserting a bronchoscope: inserting a bronchoscope through the bronchoscope insertion port 205 and the operation port exposed on the rotatable one-way valve 204 avoids interrupting the patient's respiratory support. Observe the patient's airway condition through the bronchoscope to perform diagnostic or therapeutic operations.

[0040] By using the suction tube of the present invention, the suction tube position is adjusted by rotation and the operation port is exposed, so that suction and bronchoscopy can be completed more efficiently, the operation process is simple, and the tedious steps of frequent replacement of pipes in traditional equipment are avoided, thereby improving the comfort and safety of patients.

[0041] The above-mentioned implementation cases are only preferred implementation cases of the present invention and are not any formal and substantial limitations of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and supplements without departing from the present invention, and these improvements and supplements should also be regarded as the scope of protection of the present invention.
