Description

Technical Field

[0001] This utility model relates to the field of closed suction tube technology, specifically a closed suction tube guide auxiliary connector. Background Technology

[0002] In clinical settings such as ICU, operating room, and respiratory ward, sputum suctioning is one of the most frequently used and important procedures in nursing work.

[0003] The closed suction catheter guide connector uses negative pressure to suction sputum and aspirated material from the trachea through the suction catheter, thus maintaining airway patency. Closed suction allows for continuous mechanical ventilation, ensuring relative stability of intrapulmonary pressure before and after suctioning. Closed suction is a core operation for maintaining airway patency in mechanically ventilated patients, as it ensures stable intrapulmonary pressure before and after suctioning through continuous ventilation, reducing the risk of hypoxia.

[0004] However, the above-mentioned equipment has obvious shortcomings in use. The outer diameter of the endotracheal tube connector is used in conjunction with the inner diameter of the large rotary connector of the closed suction tube. The endotracheal tube connector has a certain wall thickness. This wall thickness and the inner diameter of the large rotary connector of the closed suction tube will form an upward slope with a small inclination. When the suction tube enters the endotracheal tube connector, if the suction tube is advancing along the inner wall of the machine end, the suction tube is relatively soft. Under the action of gravity, the head of the suction tube will bend after hitting this slope, making it difficult to enter the endotracheal tube. In view of this, we propose a closed suction tube guide auxiliary connector. Utility Model Content

[0005] The purpose of this invention is to provide a sealed suction catheter guide auxiliary connector to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A closed suction catheter guide auxiliary connector includes a large rotary connector, wherein a connecting assembly is provided on the large rotary connector, and the connecting assembly includes: A stepped ramp is formed inside the large rotary joint. A short cylinder is fixedly installed on one end of the large rotary joint, a conical cylinder is fixedly installed on the other end of the short cylinder, and an arc-shaped connecting plate is fixedly installed on the other end of the conical cylinder. The mounting cylinder is fixedly installed at the other end of the arc-shaped connecting plate. A cylindrical knob is rotatably installed between the conical cylinder and the mounting cylinder. The cylindrical knob has an anti-slip groove, and a threaded auger is fixedly installed inside the cylindrical knob. A tapered auger bar is fixedly installed on the threaded auger bar. A ring is rotatably installed inside the short cylinder. A connector is snapped onto the mounting cylinder, and a flexible hose is fixedly installed on the connector.

[0007] In a further embodiment, multiple sets of the arc-shaped connecting plates and anti-slip grooves are provided, and the cylindrical knob and anti-slip grooves are arranged between multiple sets of arc-shaped connecting plates.

[0008] In a further embodiment, the large rotary joint, short cylinder, conical cylinder, mounting cylinder, cylindrical knob, connector, and hose internal spaces are interconnected.

[0009] In a further embodiment, the threaded auger bar is disposed inside the cylindrical knob, the conical auger bar is disposed inside the conical cylinder, and the ring is fixedly installed on the conical auger bar.

[0010] In a further embodiment, the mounting cylinder is provided with a snap-fit ​​assembly, the snap-fit ​​assembly including a bonding plate, the bonding plate being fixedly mounted on the mounting cylinder, the bonding plate having a slot, a thin plate being fixedly mounted on the connector head, and a locking block being fixedly mounted on the thin plate.

[0011] In a further embodiment, multiple sets of card slots and card blocks are provided, with multiple sets of card blocks disposed inside the card slots.

[0012] In a further embodiment, the bonding plate and the thin plate are bonded together, and a sealing ring is snapped onto the bonding plate and the thin plate at the bonding point.

[0013] Compared with the prior art, this utility model provides a sealed suction catheter guide auxiliary connector, which has the following beneficial effects: 1. This closed suction catheter guide auxiliary connector, in order to meet the safety and efficiency requirements of closed suction in clinical practice, is equipped with a connecting component. This component works in conjunction with the stepped ramp inside the large rotary connector to keep it flush with the inner wall of the endotracheal tube connector, eliminating the uphill surface of traditional connections and preventing the suction catheter from bending due to gravity. This allows the suction catheter to smoothly enter the endotracheal tube along the inner wall. The cylindrical knob drives the threaded auger and the conical auger to rotate, forming a guiding thrust to assist in the advancement of the soft suction catheter. There is no need to use an overly rigid suction catheter, reducing mechanical damage to the airway mucosa.

[0014] 2. This closed-type suction catheter guide auxiliary connector, in order to reduce the clinical operation risk of the device, is equipped with a snap-fit ​​component. When the connector and the installation cylinder are connected, multiple sets of snap-fit ​​blocks are precisely embedded in the slots to achieve rapid positioning and installation. Compared with the traditional threaded connection, the efficiency is improved. The bonding plate and the thin plate fit tightly together, and the sealing ring of the snap-fit ​​installation forms a double seal to avoid negative pressure leakage and ensure stable negative pressure during suctioning. The symmetrical distribution of multiple slots and snap-fit ​​blocks enhances the connection strength and prevents the connector from falling off during suctioning. Attached Figure Description

Those skilled in the art can understand the specific meaning of these terms in this application according to the specific circumstances.

[0019] Please see Figures 1-6 This utility model provides a technical solution: A closed suction catheter guide auxiliary connector includes a large rotary connector 1.

[0020] In one embodiment of this utility model, a connecting component 2 is provided on the large rotary joint 1. The connecting component 2 includes a stepped ramp 21, which is formed inside the large rotary joint 1. One end of a short cylinder 22 is fixedly installed on the large rotary joint 1, and one end of a conical cylinder 23 is fixedly installed on the other end of the short cylinder 22. One end of an arc-shaped connecting plate 24 is fixedly installed on the other end of the conical cylinder 23, and an installation cylinder 25 is fixedly installed on the other end of the arc-shaped connecting plate 24. A cylindrical knob 26 is rotatably installed between the conical cylinder 23 and the installation cylinder 25. The cylindrical knob 26 has an anti-slip groove 27, and a threaded auger 28 is fixedly installed inside the cylindrical knob 26. The conical auger 29 is fixedly installed... The short cylinder 22 is mounted on the threaded auger bar 28. A ring 210 is rotatably installed inside the short cylinder 22. A connector 211 is snapped onto the mounting cylinder 25. A hose 212 is fixedly installed on the connector 211. Multiple sets of arc-shaped connecting plates 24 and anti-slip grooves 27 are provided. A cylindrical knob 26 and anti-slip grooves 27 are provided between multiple sets of arc-shaped connecting plates 24. The internal spaces of the large rotary joint 1, short cylinder 22, conical cylinder 23, mounting cylinder 25, cylindrical knob 26, connector 211 and hose 212 are connected. The threaded auger bar 28 is located inside the cylindrical knob 26. A conical auger bar 29 is located inside the conical cylinder 23. The ring 210 is fixedly installed on the conical auger bar 29.

[0021] In this embodiment, firstly, the large rotary connector 1 is connected to the patient end of the endotracheal tube connector. The stepped ramp 21 structure inside the large rotary connector 1 keeps its inner wall flush with or slightly higher than the inner wall of the endotracheal tube connector, thus transforming the upward slope in traditional connections into a flat or downward slope. This fundamentally eliminates the obstacle of the suction tube tip bending due to gravity against the tube wall, creating a prerequisite for smooth passage of the suction tube. When suctioning is required, the medical staff holds the connector 211 at the end of the tubing 212 and pushes it towards the mounting cylinder 25. During the pushing process, if the suction tube is difficult to advance due to its soft material, the medical staff can hold the anti-slip knob 26 on the cylinder. The groove 27 rotates, and the rotation of the cylindrical knob 26 drives the internal threaded auger 28 and the connected conical auger 29 to rotate together. The rotating conical auger 29 and the threaded auger 28 will generate a forward guiding and propulsive force on the suction tube, helping it to overcome resistance and smoothly pass through the conical cylinder 23 and the short cylinder 22. Finally, it smoothly enters the endotracheal tube through the stepped ramp 21 inside the large rotary joint 1, thereby reducing the requirement for the rigidity of the suction tube. This allows for the use of a relatively softer suction tube that is safer for the patient's airway mucosa, effectively reducing the risk of mechanical damage to the mucosa. At the same time, the ring 210 is used to stabilize the rotational movement of the conical auger 29.

[0022] In one embodiment of this utility model, a buckle assembly 3 is provided on the mounting cylinder 25. The buckle assembly 3 includes a bonding plate 31, which is fixedly installed on the mounting cylinder 25. A slot 32 is provided on the bonding plate 31. A thin plate 33 is fixedly installed on the connector 211. A locking block 34 is fixedly installed on the thin plate 33. Multiple sets of slots 32 and locking blocks 34 are provided. Multiple sets of locking blocks 34 are disposed inside the slots 32. The bonding plate 31 and the thin plate 33 are bonded to each other. A sealing ring 35 is snapped onto the bonding point of the bonding plate 31 and the thin plate 33.

[0023] In this embodiment, during connection, the thin plate 33 on the connector 211 is aligned with the fitting plate 31 on the mounting cylinder 25, so that the multiple sets of locking blocks 34 on the thin plate 33 are aligned with the multiple sets of locking grooves 32 on the fitting plate 31. Then, pressure is applied until the locking blocks 34 are fully embedded in the locking grooves 32. This process is accompanied by a noticeable feeling of blockage until a click is heard, indicating that the connection is in place. Compared with the traditional threaded connection, this snap-fit ​​connection is faster and can significantly improve the efficiency of clinical operation. After the connection is completed, the fitting plate 31 and the thin plate 33 are tightly fitted together. At the same time, the sealing ring 35 that is snapped onto the outside of both forms an effective sealing interface. This double sealing structure can effectively prevent leakage during the negative pressure operation of sputum suction, ensure the stability of negative pressure, and guarantee the sputum suction effect.

The specific connection methods of each part are all conventional methods such as riveting and welding that are mature in the prior art.
