Description

Technical Field

[0001] This utility model relates to the field of tracheostomy catheter technology, and more specifically, to a tracheostomy catheter for a ventilator. Background Technology

[0002] In the medical field, ventilators are important equipment for maintaining the respiratory function of critically ill patients. Especially for patients whose spontaneous breathing ability is impaired due to various reasons, ventilators are a key component of the life support system. The tracheostomy tube (tracheostomy cannula) serves as a bridge connecting patients and ventilators, and its design is directly related to ventilation efficiency, patient comfort, and prevention of complications.

[0003] Traditional tracheostomy tube designs typically place the ventilator connection tubing directly at the tip of the tube. This design faces several problems over prolonged use; when a patient coughs up sputum, the sputum can easily enter the ventilator connection tubing, potentially causing blockage and affecting ventilation efficiency. Therefore, we have made an improvement by proposing a tracheostomy tube for ventilators. Summary of the Invention

[0004] The purpose of this invention is to address the problem that when patients cough up phlegm, the sputum that splashes out can easily enter the ventilator's connecting tubing, potentially blocking the tubing and affecting ventilation efficiency.

[0005] To achieve the above-mentioned objectives, this invention provides a tracheostomy tube for ventilators to improve the aforementioned problems.

[0006] The application is as follows:

[0007] A tracheostomy tube for a ventilator includes a tube body, a ventilator connection tube fixedly connected to the side of the tube body for connecting to a ventilator, and a funnel disposed inside the tube body for isolating the ventilator connection tube located at one end inside the tube body.

[0008] As a preferred technical solution of this application, the ventilator connecting tube is bent upwards.

[0009] As a preferred technical solution of this application, the funnel has a top opening and a bottom opening, and the diameter of the top opening of the funnel is smaller than the diameter of the bottom opening.

[0010] As a preferred technical solution of this application, one end of the ventilator connecting tube located inside the catheter body is higher than the bottom opening of the funnel and lower than the top opening of the funnel.

[0011] As a preferred technical solution of this application, the end of the catheter body away from the ventilator connecting tube is fixedly connected to a sputum drainage tube, and the position of the sputum drainage tube corresponds to the position of the bottom opening of the funnel.

[0012] As a preferred technical solution of this application, a sealing cap is provided at the top of the catheter body.

[0013] As a preferred technical solution of this application, the outer surface of the catheter body is provided with a limiting part, which is used for binding and limiting the catheter body.

[0014] As a preferred technical solution of this application, the limiting part includes a wing plate, which is disposed on the outer surface of the guide tube.

[0015] As a preferred technical solution of this application, a connection port is provided at one end of the wing plate, and a strap is fixedly connected to the other end of the wing plate.

[0016] As a preferred technical solution of this application, the strap is provided with a first Velcro strap and a second Velcro strap.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] In the scheme of this application:

[0019] To address the problem in existing technologies where sputum sprayed out during coughing can easily enter the ventilator connection tubing, potentially causing blockage and affecting ventilation efficiency, this application addresses this issue by placing the ventilator connection tubing on the side of the tubing rather than at the front. This effectively reduces the likelihood of sputum directly impacting and accidentally entering the ventilator connection tubing, thereby lowering the risk of ventilator tubing blockage and cross-infection. When sputum is coughed up, the funnel design acts as a sputum-blocking mechanism in the ventilator connection tubing, further reducing the likelihood of sputum entering the ventilator connection tubing.

[0026] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0027] As described in the background section, traditional tracheostomy tube designs typically place the ventilator connection tubing directly at the front end of the tube. This design faces some problems during long-term use. When patients cough up sputum, the sputum that splashes out can easily enter the ventilator connection tubing, potentially blocking the tubing and affecting ventilation efficiency.

[0028] To solve this technical problem, this utility model provides a tracheostomy tube for a ventilator.

[0029] For details, please refer to Figures 1-4 Tracheostomy tubes for ventilators specifically include:

[0030] The catheter body 1 has a ventilator connection tube 2 fixedly connected to its side. The ventilator connection tube 2 is used to connect to the ventilator. A funnel 3 is provided inside the catheter body 1. The funnel 3 is used to isolate the ventilator connection tube 2 located at one end inside the catheter body 1.

[0031] The tracheostomy tube for ventilators provided by this utility model effectively reduces the possibility of sputum directly impacting and accidentally entering the ventilator connecting tube 2 by placing the ventilator connecting tube 2 on the side of the tube body 1 instead of the front end. This reduces the risk of ventilator tubing blockage and cross-infection. When sputum is coughed up, the funnel 3 can block the sputum in the ventilator connecting tube 2, further reducing the possibility of sputum entering the ventilator connecting tube 2.

[0032] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0033] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0034] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0035] Example 1, please refer to Figures 1-4 A tracheostomy tube for a ventilator includes a tube body 1, with a ventilator connection tube 2 fixedly connected to the side of the tube body 1 for connecting to a ventilator. A funnel 3 is provided inside the tube body 1 to isolate the ventilator connection tube 2 located at one end inside the tube body 1. By placing the ventilator connection tube 2 on the side of the tube body 1 instead of the front end, this application effectively reduces the possibility of sputum directly impacting and accidentally entering the ventilator connection tube 2, thereby reducing the risk of ventilator tubing blockage and cross-infection. When sputum is coughed up, the funnel 3 can act as a sputum blocker in the ventilator connection tube 2, further reducing the possibility of sputum entering the ventilator connection tube 2.

[0036] Furthermore, such as Figure 3 and Figure 4 As shown, the ventilator connection tube 2 is bent upwards to further reduce the possibility of sputum entering the ventilator tubing through the ventilator connection tube 2.

[0037] Example 2 further optimizes the tracheostomy tube for ventilators provided in Example 1, specifically, as follows: Figure 4 As shown, the funnel 3 has a top opening and a bottom opening, and the diameter of the top opening of the funnel 3 is smaller than the diameter of the bottom opening. The design of the funnel 3 can reduce the backflow of the ejected sputum.

[0038] Furthermore, such as Figure 3 and Figure 4 As shown, the end of the ventilator connection tube 2 located inside the tubing body 1 is higher than the bottom opening of the funnel 3 and lower than the top opening of the funnel 3, so that the ventilator connection tube 2 is within the blocking and protective range of the funnel 3, reducing the possibility of sputum being sprayed into the ventilator connection tube 2 during sputum spraying.

[0039] Furthermore, such as Figure 4 As shown, the end of the catheter body 1 away from the ventilator connecting tube 2 is fixedly connected to the sputum drainage tube 4. The position of the sputum drainage tube 4 corresponds to the position of the bottom opening of the funnel 3. The sputum sprayed from the top opening of the funnel 3 flows back to the sputum drainage tube 4 from the outer surface of the funnel 3 and is finally discharged through the sputum drainage tube 4.

[0040] Furthermore, such as Figure 1 As shown, a sealing cap 6 is provided at the top of the catheter body 1. The sealing cap 6 can protect the top of the catheter body 1. The inner wall of the sealing cap 6 and the top of the catheter body 1 are both provided with threads, and the sealing cap 6 and the catheter body 1 are threadedly connected.

[0041] Example 3 further optimizes the tracheostomy tube for ventilators provided in Example 1 or 2. Specifically, a limiting part is provided on the outer surface of the tube body 1, which is used for binding and limiting the tube body 1.

[0042] Furthermore, such as Figure 1As shown, the limiting part includes a wing plate 5, which is disposed on the outer surface of the guide tube 1.

[0043] Furthermore, such as Figure 1 As shown, a connection port 501 is provided at one end of the wing plate 5, and a strap 502 is fixedly connected to the other end of the wing plate 5. The strap 502 has a free end. The free end of the strap 502 passes around the back of the patient's neck and through the connection port 501 to fix the wing plate 5 to the patient's throat.

[0044] Furthermore, such as Figure 1 As shown, the strap 502 is provided with a first Velcro 503 and a second Velcro 504. The free end of the strap 502 passes around the back of the patient's neck and through the connection port 501. Then the first Velcro 503 and the second Velcro 504 are glued together to achieve fixation.
