Technical Field
[0001] This utility model relates to the field of suction tube technology, specifically a dense suction tube that is easy to connect and operate. Background Technology
[0002] In clinical nursing, closed suction catheters are medical devices used to clear airway secretions and play a vital role in clinical care. They effectively remove airway secretions from the patient through a closed system, avoiding the risk of airway infection that may occur during traditional open suctioning. Currently available clump-type suction catheters, which are easy to connect and operate, require connecting to the artificial airway, ventilator tubing, and negative pressure suction tubing via a pre-installed three-way connector before use. However, considering that some novice medical staff may not be proficient in the operation and may exert excessive force during the connection process, the main tracheal connector may easily loosen or detach from the pre-embedded endotracheal tube, increasing the number of times the trachea needs to be reconnected and prolonging the preparation time before using the suction catheter. To address these issues, a clump-type suction catheter that is easy to connect and operate is proposed. Utility Model Content
[0003] The purpose of this utility model is to provide a clump-type suction catheter that is easy to connect and operate, in order to solve the problem mentioned in the background art that when the existing clump-type suction catheters that are easy to connect and operate are subjected to large pulling force, the main tracheal interface is easily loosened and detached from the pre-embedded endotracheal tube.
[0004] To achieve the above objectives, this utility model provides the following technical solution: A clump-type suction catheter for easy connection and operation includes a rotary switch. A short tube on the left side of the rotary switch, away from the rotary switch, is connected to an endotracheal intubation interface. A pre-installed endotracheal plug is inserted into the endotracheal intubation interface on the side away from the left side of the short tube. An outer ring is fixedly connected to the outside of the endotracheal intubation interface. A limiting short rod is slidably connected to the right side of the inner side of the outer ring. A hinged buckle is fixedly connected to the left side of the limiting short rod. A hinged short shaft is rotatably connected to the middle of the hinged buckle. A movable long rod is fixedly connected between the two hinged short shafts. A locking block is fixedly connected to the movable long rod on the side away from the limiting short rod. A pull rod, slidably connected to the outer ring, is fixedly connected to the right side of the limiting short rod. A spring is sleeved on the outside of the pull rod. A torsion spring is sleeved in the gap between the hinged short shaft and the hinged buckle. A traction outer ring is fixedly connected to the pull rod on the side away from the limiting short rod. A movable notch is provided on the outer surface of the outer ring.
[0005] Preferably, the side of the short tube on the right side of the rotary switch away from the rotary switch is connected to a suction tube interface, and the upper part of the short tube on the right side of the rotary switch is connected to a second bend interface.
[0006] Preferably, the upper part of the left short tube of the rotary switch is connected to a ventilator interface, and the lower part of the left short tube of the rotary switch is connected to a first bend interface. The inlet ends of the first bend interface and the second bend interface are both connected to a conical connector structure, and the first bend interface and the second bend interface are L-shaped.
[0007] Preferably, the number of movable notches corresponds one-to-one with the number of movable long rods, and the arrangement positions of the movable long rods and the arrangement positions of the movable notches are arranged opposite to each other. The movable long rods are rotatably connected together by a hinged short shaft and a hinged buckle plate, and the shape of the hinged short shaft is a "T" shaped structure.
[0008] Preferably, the outer outer ring and the traction outer ring are coaxially arranged, the traction outer ring is located outside the endotracheal tube interface, one side of the traction outer ring is fixedly connected to one side of the spring, the other side of the spring is fixedly connected to one side of the traction outer ring, and the front and rear ends of the torsion spring are respectively fixedly connected to the outer convex plate of the hinged short shaft and the hinged buckle plate.
[0009] Compared with the prior art, the beneficial effects of this utility model are: In this invention, the inclusion of an outer outer ring, a movable long rod, a locking block, a movable notch, a limiting short rod, a hinged buckle plate, a hinged short shaft, a pull rod, a spring, a torsion spring, and a traction outer ring facilitates the connection of the ductal suction tube. After the endotracheal tube is connected via the endotracheal intubation interface, the spring-loaded locking structure, composed of the outer outer ring, movable long rod, locking block, movable notch, limiting short rod, hinged buckle plate, hinged short shaft, pull rod, spring, torsion spring, and traction outer ring, reinforces and limits the connection between the endotracheal tube and the endotracheal intubation interface. This prevents the endotracheal tube connection assembly from loosening due to excessive subsequent connection tension, and also reduces the number of times the endotracheal tube needs to be reconnected.

A movable long rod 5 is fixedly connected between the two hinged short shafts 10. A locking block 6 is fixedly connected to the side of the movable long rod 5 away from the limiting short rod 8. A pull rod 11 is fixedly connected to the right side of the limiting short rod 8 and is slidably connected to the outer ring 4. A spring 12 is sleeved on the outside of the pull rod 11. A torsion spring 13 is sleeved in the gap between the hinged short shaft 10 and the hinged buckle plate 9. A traction outer ring 18 is fixedly connected to the side of the pull rod 11 away from the limiting short rod 8. An movable notch 7 is opened on the outer surface of the outer ring 4.
[0014] like Figure 1 As shown, the side of the short tube on the right side of the rotary switch 1 away from the rotary switch 1 is connected to a suction tube interface 14. The upper part of the short tube on the right side of the rotary switch 1 is connected to a second bend interface 17. The second bend interface 17 and the suction tube interface 14 facilitate the connection of the medical device to the flushing line and the suction line. The upper part of the short tube on the left side of the rotary switch 1 is connected to a ventilator interface 16. The lower part of the short tube on the left side of the rotary switch 1 is connected to a first bend interface 15. The inlet ends of the first bend interface 15 and the second bend interface 17 are both connected to a conical connector structure. The first bend interface 15 and the second bend interface 17 are L-shaped. The first bend interface 15 is designed to assist the medical device in connecting to the drug infusion line.
[0015] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the number of movable notches 7 corresponds one-to-one with the number of movable long rods 5. The arrangement of the movable long rods 5 and the arrangement of the movable notches 7 are arranged opposite each other. The movable long rods 5 are rotatably connected together by the hinged short shaft 10 and the hinged buckle plate 9. The hinged short shaft 10 has a "T" shaped structure. The reserved setting of the movable notches 7 serves to assist the movable long rods 5 in flipping outward and unfolding. The outer ring 4 and the traction outer ring 18 are coaxially arranged. The traction outer ring 18 is set outside the endotracheal tube interface 2. One side of the traction outer ring 18 is fixedly connected to one side of the spring 12, and the other side of the spring 12 is fixedly connected to one side of the traction outer ring 18.

[0016] Workflow: Before using the medical device of this utility model, it is necessary to ensure that the endotracheal tube is pre-inserted into the patient's oral cavity or nasal cavity. Before using the clump-type suction tube to perform sputum suction on the patient, when multiple tube connections are required, firstly, with the auxiliary connection of the outer ring 4, push the traction outer ring 18 to the left, so that the pull rod 11 overcomes the rebound force generated by the spring 12 and is pushed into the inner part of the outer ring 4. The limiting short rod 8 will be pushed outward through the hinge assembly to obtain the movable long rod 5. After being pushed out in place, under the connection of the hinge buckle plate 9, the torsion spring 13, which was originally in a compressed state, begins to release and rebound. The movable long rod 5 will flip outward with the locking block 6 and lock into the inner part of the movable notch 7, realizing tilting and outward unfolding. Then, align with the reserved endotracheal tube and insert the reserved endotracheal tube plug 3 into the endotracheal tube interface 2. After being inserted in place, release the traction outer ring 18, and the spring 12 begins to release. The springback mechanism, along with lever 11, short lever 8, and movable long lever 5, extends to the right to a certain extent. Once fully extended, the movable long lever 5 retracts back into the outer ring 4 along with short lever 8, and the movable long lever 5, along with locking blocks 6, automatically flips back to its original horizontal position. The four locking blocks 6 precisely lock the pre-installed endotracheal plug 3, making its connection with the endotracheal tube interface 2 more secure. Then, following standard medical procedures, the suction tube interface 14 can be connected to the suction port with graduations, and the ventilator interface 16 can be connected to the ventilator's inlet and outlet tubing. Through the pre-installed conical connector structure, the first bend interface 15 and the second bend interface 17 can be connected to the irrigation fluid tubing and the drug delivery tubing, respectively. This completes the multi-tube connection operation, allowing medical staff to suction out sputum from the patient's airway according to standard suctioning techniques.
