Description

Technical Field

[0001] This utility model relates to a veterinary visual endotracheal tube, belonging to the field of endotracheal tube technology. Background Technology

[0002] A veterinary endotracheal tube is a medical device used to maintain a patent airway in animals during anesthesia or emergency care, and is widely used in veterinary clinical practice. The functions of a veterinary endotracheal tube are: maintaining airway patency: ensuring the animal can breathe normally during anesthesia or emergency care; assisting ventilation: providing mechanical ventilation support to the animal by connecting to a ventilator through the tube; and preventing aspiration: reducing the risk of gastric contents reflux into the airway during anesthesia. They are classified by material into silicone tubes and PVC tubes. Silicone tubes are soft and durable, suitable for prolonged use, while PVC tubes are less expensive and suitable for single use. Veterinary endotracheal tubes are an important tool in veterinary clinical practice, used in scenarios such as anesthesia, emergency care, and intensive care. Correct selection and use of the tube can effectively ensure the respiratory safety of animals.

[0003] When performing surgery or emergency treatment on an animal, the first step is to use a laryngoscope (which provides a light source and presses down on the base of the tongue) to open the animal's mouth. Next, an endotracheal tube is inserted into the mouth and trachea, typically from the lips to the tip of the tracheal branch. After inflation, the air sac expands and is fixed to the trachea. Then, oxygen or anesthetic gas is connected to perform the medical procedure.

[0004] During animal treatment, the lack of cooperation from the animal may make it difficult to operate quickly, especially when intubating animals with narrow mouths. This can make it difficult to insert the tracheal tube smoothly, and poor visibility may also lead to problems such as incomplete insertion or damage to the animal's trachea, thus affecting the smooth insertion of the tracheal tube.

Detailed Implementation

[0029] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0030] like Figure 1-6 As shown, the veterinary visual endotracheal cannula includes:

[0031] The tube body 1 has a connector 2 and a front airbag 12 fixedly connected to both ends. A rigid tube 9 is movably sleeved on the surface of the tube body 1 and is fixedly connected to the rear airbag 10. An illumination lamp 3 is provided inside the front end of the tube body 1. A viewing lens 6 is provided inside the tube body 1 at the illumination lamp 3 and is connected to the inner wall of the tube body 1 through a reset mechanism. The front airbag 12 and the rear airbag 10 are connected by a connecting tube 13, which is located inside the tube body 1. The connector 2 is connected to a sealing plug 15 through a connecting strap 14. The connecting tube 13 is fixedly connected to both ends of a three-way pipe 19. One end of the three-way pipe 19 is fixedly connected to a valve 22, and the other end of the three-way pipe 19 is connected to an air intake pipe 21.

[0032] The tube body 1 is made of a flexible structural material. One end of the tube body 1 is sleeved with the connector 2, and the inside of the connector 2 is fitted with the sealing plug 15. One end of the sealing plug 15 is fixedly connected with a rubber ring 16. A notch 18 is opened on one side of the sealing plug 15. The inside of the sealing plug 15 is inserted through the connecting pipe 17, and the connecting pipe 17 is connected to the oxygen or anesthetic gas pipeline. The viewing lens 6 is fixedly connected to the connecting line 5. The surface of the connecting line 5 is provided with a tensile sleeve, and the connecting line 5 is located inside the tube body 1.

[0033] In this technical solution, after the tube body 1 is inserted into the animal's trachea, the connecting tube 13 and the connecting line 5 are both located inside the tube body 1. When the sealing plug 15 is inserted, the connecting tube 13 and the connecting line 5 are both located at the notch 18, which facilitates the easy insertion of the sealing plug 15. At this time, the deformation of the rubber ring 16 abuts against the connecting line 5 and the connecting tube 13 to block the tube body 1, which facilitates the subsequent delivery of oxygen or anesthetic gas.

[0034] The reset mechanism consists of a fixing block 4, with a connecting line 5 inserted through the inside of the fixing block 4. The fixing block 4 is connected to the viewing lens 6 via a spring 7, and the connecting line 5 is sleeved inside the spring 7. The fixing block 4 is fixedly connected to the inner wall of the tube body 1 via a support rod. The inner wall of the tube body 1 is fitted and connected to the annular scraper 8, and the scraper 8 is connected to the edge of the viewing lens 6 via multiple elastic strips. The scraper 8 is located between the fixing block 4 and the lighting lamp 3, and the scraper 8 is an elastic structure distributed corresponding to the lighting lamp 3.

[0035] In this technical solution, during insertion, one end of the tube body 1 is held and the connecting wire 5 is pulled. The connecting wire 5 pulls the viewing lens 6 to the front end of the tube body 1. At this time, the lighting lamp 3 provides illumination, and the viewing lens 6 captures the front view of the tube body 1 in real time. When the lighting lamp 3 is contaminated by mucus or other substances, the connecting wire 5 is loosened appropriately, so that the elasticity of the spring 7 can move the lens forward a certain distance and move the scraper 8 out. When the scraper 8 contacts the surface of the lighting lamp 3, it removes the dirt. Then, the connecting wire 5 is pulled to retract the viewing lens 6, so that the scraper 8 will not block the lighting lamp 3, thus improving the lighting effect. The sleeve on the connecting wire 5 can improve the tensile strength and increase the service life.

[0036] The connecting pipe 13 penetrates the inner wall of the pipe body 1 and communicates with the front airbag 12. The outer diameter of the front airbag 12 is smaller than the outer diameter of the rear airbag 10, and the surface of the rear airbag 10 is provided with a reinforcing layer 11. One end of the three-way pipe 19 is threadedly connected to the screw cap 20, and the screw cap 20 is fixedly connected to the air inlet pipe 21. Two valves 22 are provided on the three-way pipe 19. The two valves 22 correspond to the two connecting pipes 13 respectively, and the two valves 22 are located on both sides of the three-way pipe 19 respectively.

[0037] In this technical solution, before endotracheal intubation, the rear air bladder 10 is moved to move the rigid tube 9 on the surface of the tube body 1, so that the front air bladder 12 and the rear air bladder 10 come into contact with each other. At this time, the rear air bladder 10 is placed inside the animal's oral cavity, and the front end of the tube body 1 does not extend too far into the larynx. At this time, one of the valves 22 is closed, and the cap 20 is tightened on the three-way tube 19. The air inlet tube 21 is connected to an external air source so that gas enters the connecting tube 13 from one end of the three-way tube 19 and enters the rear air bladder 10. When the rear air bladder 10 inflates, it opens the animal's oral cavity. With the end airbag 10 fixed in the animal's mouth, the tube 1 can move inside the rigid tube 9. At this time, while holding the connecting line 5, the tube 1 is slowly inserted into the trachea by relying on the viewing lens 6, which allows for real-time observation during the insertion process. After the tube 1 is inserted into place, another valve 22 is opened to allow gas to enter the front airbag 12 from the other end of the three-way tube 19, causing it to inflate and be fixed on the trachea. At this time, after blocking the sealing plug 15, oxygen or anesthetic gas is connected to the connecting tube 17 to be delivered to the trachea through the tube 1 to achieve the therapeutic function.
