Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a tracheal intubation device for multi-directional subglottic suction. Background Technology

[0002] Subglottic suction refers to the method of using an endotracheal tube with a subglottic suction structure to directly suction secretions accumulated above the cuff through negative pressure. Subglottic suction helps clear secretions accumulated above the cuff, reducing the incidence of ventilator-associated pneumonia (VAP) and shortening the duration of mechanical ventilation.

[0003] Currently, the endotracheal tubes with subglottic suction structures commonly used in clinical practice have the following defects: the subglottic suction structure has only a single opening above the cuff, which can only suction sputum at the opening. It is difficult to clear sputum from other locations, and in other locations, sputum is very likely to accumulate in a viscous manner. When the patient coughs violently or the cuff is deflated, the viscous accumulated sputum will fall into the airway and cause ventilator-associated pneumonia. Utility Model Content

[0004] The purpose of this invention is to provide a multi-directional subglottic suction endotracheal intubation device that addresses the current state of the technology. This device can achieve multi-directional subglottic suction, thoroughly clear sputum above the cuff, prevent sputum accumulation above the cuff, prevent lung infection, and improve patient prognosis.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A multi-directional subglottic suction endotracheal intubation device includes an endotracheal tube, an endotracheal connector, a cuff, an inflation tube, and an inflation connector. The endotracheal connector is connected to the upper end of the endotracheal tube. The cuff is fixed to the endotracheal tube. The endotracheal tube has an inflation channel on its wall, with one end of the inflation channel connected to the cuff and the other end connected to the inflation connector via the inflation tube. The device also includes a manifold and a suction connector. The endotracheal tube has three or four suction channels on its wall, which are evenly arranged around the circumference of the endotracheal tube. One end of each suction channel is located above the cuff, and the other end is connected to the inlet end of the manifold via the suction tube. The outlet end of the manifold is connected to the suction connector.

[0007] Furthermore, the suction connector tubing includes a syringe connector, a suction connector, and a Y-shaped tube. The Y-shaped tube has a first interface and two second interfaces. The first interface of the Y-shaped tube is connected to the outlet end of the manifold. The syringe connector and the suction connector are respectively connected to the two second interfaces of the Y-shaped tube, and both the syringe connector and the suction connector are provided with end caps.

[0008] Furthermore, the end caps on the syringe connector and the suction connector are connected to the Y-shaped tube via an anti-loss rope.

[0009] Furthermore, the manifold is provided with a main channel and branch channels extending inward along its side. The number of branch channels is the same as the number of suction tubes, and each branch channel is connected to the main channel. The main channel is provided with a first connector connected to it, and the branch channel is provided with a second connector connected to it.

[0010] Furthermore, the combiner is made of polytetrafluoroethylene (PTFE).

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings.

[0021] Please see Figures 1-2 As shown, a multi-directional subglottic suction endotracheal intubation device includes an endotracheal tube 1, an endotracheal connector 2, an air bag 3, an inflation tube 4 (soft tube), and an inflation connector 5. The endotracheal connector 2 is connected to the upper end of the endotracheal tube 1. The air bag 3 is fixed on the endotracheal tube 1. An inflation channel (not shown in the figure) is provided on the wall of the endotracheal tube 1, and one end of the inflation channel is connected to the air bag 3, while the other end is connected to the inflation connector 5 through the inflation tube 4.

[0022] The inflation connector 5 contains a pressure sensor and a one-way inflation valve. When in use, air is inflated into the airbag 3 through the inflation channel provided on the wall of the tracheal tube 1.

[0023] The above technical solution also includes a manifold 9 and a suction connector tubing. The endotracheal tube 1 has three or four suction channels 6 on its wall. The suction channels 6 are evenly arranged around the circumference of the endotracheal tube 1. One end of the suction channel 6 is located above the cuff 3, and the other end is connected to the inlet end of the manifold 9 through the suction tube 7 (soft tube). The outlet end of the manifold 9 is connected to the suction connector tubing.

[0024] The manifold 9 connects the suction tubes 7 corresponding to each suction channel 6 to the suction connector tubing. When in use, the suction channel 6 on the wall of the endotracheal tube 1 is used to suction and remove sputum above the air bag 3.

[0025] According to the above design, the endotracheal intubation device can achieve multi-directional subglottic suction, thoroughly clear sputum from the upper three sides of the cuff, avoid sputum accumulation above the cuff, prevent lung infection, and improve patient prognosis.

[0026] Specifically, the manifold 9 has a main channel 901 and a branch channel 902 extending inward along its side. The number of branch channels 902 is the same as the number of suction tubes 7, and each branch channel 902 is connected to the main channel 901. The main channel 901 is provided with a first connector 11 (the first connector 11 serves as the outlet end of the manifold 9), and the branch channel 902 is provided with a second connector 10 (the second connector 10 serves as the inlet end of the manifold 9).

[0027] In this embodiment, for example, the manifold 9 is made of polytetrafluoroethylene material; the first connector 11 and the main channel 901 and the second connector 10 and the branch channel 902 are all threaded connections.

[0028] Please see Figure 2As shown, in one embodiment, the suction connector tubing includes a syringe connector 13, a suction connector 14, and a Y-shaped tube 12. The Y-shaped tube 12 has a first interface and two second interfaces. The first interface of the Y-shaped tube 12 is connected to the outlet end of the manifold 9. The syringe connector 13 and the suction connector 14 are respectively connected to the two second interfaces of the Y-shaped tube 12, and both the syringe connector 13 and the suction connector 14 are provided with end caps 15. The Y-shaped tube 12 includes a tee connector, and each interface of the tee connector is connected to a tube segment (tight tubing).

[0029] Preferably, the end caps 15 on the syringe connector 13 and the suction connector 14 are connected to the Y-tube 12 by an anti-loss rope 16 to prevent the end caps 15 from being lost.

[0030] In this embodiment, for example, the anti-loss rope 16 and the end cap 15 are integrally formed.

[0031] According to the above design, this endotracheal intubation device can be adapted for both syringe suction and suction device suction, making it convenient and flexible for medical personnel to operate. It is particularly important to note that when suctioning with a syringe, the corresponding end cap 15 must be used to seal the suction device connector 14; when suctioning with a suction device, the corresponding end cap 15 must be used to seal the syringe connector 13.

[0032] Please see Figure 1 As shown, in one embodiment, a bundle sleeve 8 is provided on the suction tube 7 between the suction channel 6 and the manifold 9 to prevent the suction tube 7 from becoming scattered or tangled.

[0033] Preferably, the cluster sleeve 8 is provided with cluster channels (not shown in the figure) that match the number of suction tubes 7, and the suction tubes 7 are inserted one by one into the cluster channels provided in the cluster sleeve 8.
