Description

Technical Field

[0001] This utility model relates to the field of medical devices, specifically a tubing fixing device. Background Technology

[0002] In intensive care units, many patients with endotracheal intubation or tracheotomy require invasive mechanical ventilation to sustain their lives. Although improvements to ventilator tubing have significantly reduced water accumulation in recent years, various factors, such as the ventilator's heating base and heating wires, still cause condensation to form in the tubing after contact with cold air. This condensation sometimes accumulates in the suction extension tube and enters the patient's airway during ventilation, triggering a coughing reflex. Simultaneously, the patient's sputum is aspirated into the ventilator circuit, posing a risk of microaspiration and contaminating the tubing, necessitating tubing replacement and increasing the patient's financial burden. This also reduces the ventilator's practicality. Utility Model Content

[0003] The purpose of this invention is to provide a tubing fixing device that connects the patient end and the ventilator end through connecting tubes, and collects condensate in the tubing through a guide tube. After collecting a certain amount of condensate, it is suctioned out from the suction port to prevent condensate from entering the patient's airway and causing aspiration. In addition, the spherical airbag can strengthen the stability of the tubing and reduce the traction on the artificial airway caused by the weight of the device, making it more practical.

[0004] To achieve the above objectives, this utility model employs the following technical solution:

[0005] A tubing fixing device includes a connecting tube, with its two ends connected to a patient end and a ventilator end respectively via tubing. The connecting tube is also provided with a guide tube, and the connecting tube and the guide tube form a T-shaped structure. The guide tube is internally divided into two cavities by a partition, and the two cavities correspond to the patient end and the ventilator end respectively. The guide tube is covered with a spherical air bag, and the spherical air bag is provided with an inflation nozzle. The bottom end of the guide tube passes through the spherical air bag and is provided with a suction port, and two suction ports are also provided corresponding to the two cavities.

[0006] Furthermore, the bottom of the spherical airbag is provided with water bladders located on both sides of the guide tube, and the water bladders are provided with water inlets.

[0007] Furthermore, the top of the guide tube has a funnel-shaped structure.

[0008] Furthermore, the top of the partition is provided with a cross-shaped grid support, and the two ends of the grid support in the horizontal direction are in contact with the inner wall of the opening at the top of the guide pipe.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] This patented technology incorporates a connecting tube, with one end connected to the patient's suction extension tube and the other end connected to the ventilator tubing. The connecting tube is integrated with the guide tube in a T-shape, allowing condensate from the ventilator tubing to flow through the connecting tube into the corresponding cavity of the guide tube for collection and accumulation at the bottom. Simultaneously, small amounts of sputum and condensate from the suction extension tube also flow into the corresponding cavity of the guide tube for collection. When the condensate volume in the cavity exceeds half its capacity, it can be suctioned out through the suction port. This prevents condensate from accumulating in the suction extension tube and entering the patient's airway during ventilation, thus avoiding accidental suction and choking reflexes, ensuring patient safety. It also prevents sputum from being aspirated into the ventilator circuit during coughing, reducing the cost of replacing ventilator tubing. Furthermore, the inflatable spherical cuff provides support for the ventilator tubing, reinforcing its stability and reducing traction on the artificial airway caused by the tubing's gravity.

[0014] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.

[0015] This utility model describes a tubing fixing device. The main structure includes a connecting pipe 1, with its two ends connected to the patient's suction extension tube and the ventilator end respectively via tubing. A guide tube 2 is also provided on the connecting pipe 1. The connecting pipe 1 and the guide tube 2 form a T-shape. The guide tube 2 is internally divided into two cavities by a partition 3, with each cavity corresponding to the suction extension tube end and the ventilator end, respectively. This allows condensate generated in the ventilator tubing and suction extension tube to flow into the corresponding cavities for collection. A spherical air bag 4 is fitted over the guide tube 2, and the spherical air bag 4 has an inflation nozzle 5. Inflation of the spherical air bag 4 through the inflation nozzle 5 causes it to expand, providing support for the ventilator tubing and preventing sagging. To prevent bending that could affect the patient's breathing and to reduce traction on the artificial airway due to the gravity of the tubing, the bottom end of the guide tube 2 is connected to the spherical air bag 4 and has a suction port 6. There are two suction ports 6 corresponding to the two cavities. The condensate generated in the ventilator tubing can flow into the corresponding cavity of the guide tube 2 through the connecting tube 1 and be collected and accumulated at the bottom of the guide tube 2. At the same time, a small amount of sputum and condensate in the suction extension tube can also flow into the corresponding cavity of the guide tube 2 for collection. When the amount of condensate in the cavity exceeds 1 / 2, it can be suctioned out through the suction port 6. A syringe can be used to connect to the suction port 6 for suctioning to prevent the condensate in the ventilator tubing from accumulating at the suction extension tube and entering the patient's airway with ventilation, thus avoiding the patient's aspiration and coughing reflex.

[0016] Preferably, the bottom of the spherical airbag 4 is provided with water bladders 7 located on both sides of the guide tube 2. The water bladders 7 are provided with water inlets 8. By injecting water into the water bladders 7, the weight of the spherical airbag 4 is increased to a certain extent, maintaining the stability of the bottom of the spherical airbag 4, reducing the drag on the ventilator tubing caused by the patient's movements, and further reducing the traction on the artificial airway caused by the gravity of the tubing.

[0017] Preferably, the top of the guide pipe 2 has a funnel-shaped structure, which can better guide the condensate flowing into the connecting pipe 1 into the guide pipe 2 for collection.

[0018] Preferably, the top of the partition 3 is provided with a cross-shaped grid support 9. The two ends of the grid support 9 in the horizontal direction are in contact with the inner wall of the top opening of the guide tube 2, so that the grid support 9 plays a filtering role. The grid support 9 can filter and block small foreign objects from entering the tube from the patient's mouth, avoid clogging the guide tube 2 and the suction port 6, and thus ensure that the condensate in the ventilator tube can be suctioned normally.

[0019] This patent allows condensate generated in the ventilator tubing to flow into the corresponding cavity of the guide tube 2 through the connecting tube 1 and collect at the bottom of the guide tube 2. At the same time, a small amount of sputum and condensate in the suction extension tube can also flow into the corresponding cavity of the guide tube 2 for collection. When the amount of condensate in the cavity exceeds 1 / 2, it can be suctioned out through the suction port 6, preventing condensate in the ventilator tubing from accumulating at the suction extension tube and entering the patient's airway with ventilation. This avoids the patient accidentally aspirating and triggering a cough reflex, ensuring patient safety. It also prevents sputum from being aspirated into the ventilator circuit when the patient coughs, reducing the cost of replacing the ventilator tubing. In addition, the inflated spherical cuff 4 can provide support for the ventilator tubing, and the water-filled spherical cuff 7 increases the weight at the bottom of the spherical cuff after being filled with water, which can strengthen the stability of the ventilator tubing and reduce the traction on the artificial airway caused by the gravity of the tubing.
