Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a connection device for the end of an endotracheal intubation / stomosis. Background Technology

[0002] Endotracheal intubation and tracheotomy are crucial procedures for maintaining airway patency in clinical emergency and intensive care. During these procedures, connecting devices such as ventilators, oxygen therapy equipment, and airway humidifiers are used to link to the patient's artificial airway to assist with ventilation, oxygen therapy, and airway care. However, suctioning, a key step in the routine care of these patients, often involves the splashing of sputum and aerosols, which can easily lead to the spread of pathogens and increase the risk of infection for healthcare workers.

[0003] In existing technologies, endotracheal intubation (tracheostomy) end-connection devices have limited functionality, typically supporting only a single device (such as a ventilator or oxygen delivery system), and cannot simultaneously meet multiple needs such as oxygen delivery, humidification, ventilator support, and splash-proof suctioning. For example:

[0004] Functional limitations: Traditional connectors lack integrated design, requiring frequent replacement of different devices, which leads to cumbersome operation and is prone to contamination of the connection port;

[0005] Splash protection defect: During suctioning, sputum and aerosols can easily be sprayed out through the gap between the suction tube and the interface, resulting in insufficient protection.

[0006] Insufficient flexibility: Most existing devices are fixed structures, which cannot adjust the angle according to the patient's position or treatment needs, affecting the ease of operation.

[0007] Although some improvement solutions attempt to optimize splash prevention by adding sealing structures or suction channels, the following problems still exist:

[0008] The complex sealing structure affects operational efficiency.

[0009] The suction channel and suction tube have poor compatibility, and the anti-splash effect is unstable;

[0010] Lacking steering capability, it cannot adapt to complex clinical scenarios.

[0011] Therefore, an end connector with anti-splash and steering functions urgently needs to be studied. Summary of the Invention

[0012] The purpose of this invention is to solve the problems mentioned in the background art by providing a splash-proof diverter for endotracheal intubation / stomosis, which solves the problems of single function, high risk of splashing and insufficient operational flexibility in the prior art, thereby improving the safety and convenience of medical operations.

[0013] To solve the above technical problems, the technical solution provided by the present invention is: a splash-proof diverting connector for the end of endotracheal intubation / stomosis, including a connector main body, the connector main body being a bottomless cylinder, the connector main body having a first connecting part, a second connecting head, and a third connecting head on its side, the second connecting head and the third connecting head being located on the same side, and the first connecting part being located on the opposite side of the second connecting head and the third connecting head;

[0014] The first connecting part has the same inner diameter as the main connector, and the first connecting part is horizontally inclined downward.

[0015] The second connector and the third connector are used to connect the oxygen inhalation device and the airway humidification device, respectively, and the second connector and the third connector are set horizontally upward.

[0016] The top of the connector tube is provided with a suction tube hole, and the top side of the connector tube is provided with a cap through a connecting strip. The cap is used in conjunction with the suction tube hole.

[0017] The bottom of the main connector is a bottom connector, and a steering mechanism is provided inside the bottom connector.

[0018] As a preferred embodiment, the steering mechanism is a universal joint or a rotary shaft structure.

[0019] As a preferred embodiment, the first connecting part, the second connecting head, and the third connecting head are all provided with sealing rings or sealing thread structures to ensure the airtightness of the connection.

[0020] As a preferred embodiment, the cap is provided with an elastic sealing gasket on the outside to maintain a seal when it is inserted into the suction tube hole.

[0021] As a preferred embodiment, the main connector, the first connecting part, the second connecting head, and the third connecting head are made of medical-grade polycarbonate or biocompatible polymer materials.

[0022] The advantages of this invention compared to existing technologies are: integrated design and multi-functional interfaces reduce the frequency of equipment replacement and lower the risk of infection; highly efficient splash protection, with a double-sealed structure that reduces aerosol leakage rate by more than 90%; flexible steering to adapt to different body positions and operating angles, improving the comfort of medical staff; and safe materials, with medical-grade materials that are corrosion-resistant, biocompatible, and suitable for long-term use.

Furthermore, terms such as "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0029] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or a point connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0030] Referring to the accompanying drawings, a splash-proof diverter for endotracheal intubation / cutoff ends includes a main connector 1, which is a bottomless cylinder. The main connector 1 has a first connecting part 2, a second connecting head 3, and a third connecting head 4 on its side. The second connecting head 3 and the third connecting head 4 are located on the same side, and the first connecting part 2 is located on the opposite side of the second connecting head 3 and the third connecting head 4.

[0031] The first connecting part 2 has the same inner diameter as the main connector 1, and the first connecting part 2 is set horizontally downward.

[0032] The second connector 3 and the third connector 4 are used to connect the oxygen inhalation device and the airway humidification device, respectively. The second connector 3 and the third connector 4 are set horizontally upward at an angle.

[0033] The top of the connector tube 1 is provided with a suction tube hole 5, and the top side of the connector tube 1 is provided with a cap 7 via a connecting strip 6. The cap 7 is used in conjunction with the suction tube hole 5.

[0034] The bottom of the main connector 1 is the bottom connector 8, and the bottom connector 8 is equipped with a steering mechanism 9.

[0035] Steering mechanism 9 is a universal joint or rotary shaft structure.

[0036] The first connecting part 2, the second connecting head 3, and the third connecting head 4 are all equipped with sealing rings or sealing thread structures to ensure the airtightness of the connection.

[0037] The cap 7 has an elastic sealing gasket on the outside to maintain a seal when it is inserted into the suction tube hole 5.

[0039] In a specific implementation of this invention, the steering mechanism is located inside the bottom joint and adopts a universal joint structure. It achieves multi-directional rotation through a spherical hinge, and the friction force is adjustable to adapt to different operating requirements. Each connector and suction tube hole is equipped with a silicone sealing ring or threaded sealing structure to ensure airtightness. The cap is fixed to the main body by a buckle, and only requires light pressure or rotation to open and close, making operation convenient.

[0040] Operating method

[0041] During the suctioning procedure, first confirm that the connector is tightly connected to the end of the endotracheal tube, and that the ventilator, oxygen supply, and humidification device are connected to the corresponding interfaces; gently press the top of the cap, rotate it 90°, and remove the cap to expose the suction tube hole; vertically insert the disposable DRE suction tube into the hole until it reaches the target position of the endotracheal tube; start negative pressure suction, and the sputum is discharged through the suction tube, while the aerosol is confined inside the connector; after suctioning, remove the suction tube, reset the cap, and tighten it, ensuring that the elastic sealing gasket completely seals the opening.

[0042] Working principle

[0043] Anti-splash principle: The interference fit between the suction catheter and the suction catheter hole forms the first barrier, and the elastic sealing gasket of the cap is the second line of defense, thus doubly blocking splashes;

[0044] Function of the steering mechanism: The universal joint adjusts friction through an internal spring, allowing medical staff to adjust the joint angle with one hand and prevent tubing from twisting;

[0045] Multi-interface collaboration: The ventilator, oxygen supply and humidification device work through independent channels without interfering with each other, ensuring the continuity of treatment.

[0046] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
