Description

Technical Field

[0001] This utility model relates to the field of laryngeal stoma technology, specifically to an expandable stoma balloon catheter. Background Technology

[0002] Balloon catheters are used to provide assisted ventilation to patients during anesthesia. In the field of laryngostomy, balloon catheters can be used to dilate stoma stenosis after total laryngoma surgery, ensuring air delivery while preventing suffocation and coughing. Through clinical use research, the inventors of this application have found that existing balloon catheters mostly use a spherical or conical balloon design. However, the small contact area between the spherical or conical balloon and the stoma makes it prone to slippage due to increased sputum or patient movement. Furthermore, the relatively long catheter length can affect sputum drainage and increase the difficulty of operation. Therefore, there is an urgent need to improve existing balloon catheters. Utility Model Content

[0003] The existing balloon catheters mostly use a spherical or conical design for the balloon, but the spherical or conical balloon has a small contact area with the stoma, which is easy to slip off due to increased sputum or patient movement. In addition, the catheter is long, which can affect the discharge of sputum and increase the difficulty of operation. This utility model provides a balloon catheter that can expand the stoma.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] An expandable stoma balloon catheter includes a catheter, one end of which is fixedly connected to an intubation tube, the outer end of which is fixedly connected to a first connector communicating with the catheter, the other end of which is designated as an insertion end, and a balloon fixedly connected around the catheter near the insertion end, the width of the balloon at both ends being greater than the width at the middle, a ventilation tube fixedly connected to the balloon, a cuff fixedly connected to the end of the ventilation tube away from the balloon, and a second connector communicating with the ventilation tube fixedly connected to the cuff.

[0006] Compared with existing technologies, the expandable stoma cuff catheter provided by this utility model has two advantages. First, by wrapping and fixing the cuff around the catheter near the insertion end, and with the width at both ends of the cuff being greater than the width in the middle, the cuff is designed as a concave structure that is wider at both ends and narrower in the middle. This increases the contact area with the stoma, effectively improving its fixation within the patient's airway and preventing slippage or aspiration due to increased sputum or patient movement, thus improving safety during respiration. Second, by fixing an intubation tube to one end of the catheter, and fixing a first connector connected to the catheter at the outer end of the intubation tube, one end of the catheter can be cut according to actual needs, and then the intubation tube with the first connector fixedly connected can be fixedly inserted into the catheter. That is, the length of the catheter can be cut according to actual needs, thereby reducing the space occupied by the catheter in the airway, facilitating the drainage of sputum, and simplifying the operation.

[0007] Furthermore, the catheter is made of medical-grade polyvinyl chloride, and the airbag is made of medical-grade silicone.

[0008] Furthermore, the catheter is provided with depth markings and multiple length markings.

[0009] Furthermore, the insertion end is a beveled cut, and the catheter inside the beveled cut is provided with a Murphy hole.

[0010] Furthermore, the airbag is fixedly connected to the conduit between the Murphy orifice and the depth marker.

[0011] Furthermore, the diameter of the first connector is larger than the diameter of the cannula, and the cannula is fixedly inserted into the inside of the catheter.

[0012] Furthermore, the bladder is equipped with a one-way valve, and the diameter of the venting tube is smaller than the diameter of the duct. Attached Figure Description

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0019] In the description of this utility model, it should be understood that the terms "longitudinal," "radial," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0020] In the description of this utility model, 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 an electrical 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 utility model based on the specific circumstances.

[0021] Please refer to Figures 1 to 4 As shown, this utility model provides an expandable stoma balloon catheter, including a catheter 1. One end of the catheter 1 is fixedly connected to an insertion tube 2. The outer end of the insertion tube 2 is fixedly connected to a first connector 3 that communicates with the catheter 1. That is, after the insertion tube 2 is inserted into one end of the catheter 1, the first connector 3 fixedly connected to the outer end of the insertion tube 2 is in communication with the catheter 1. The other end of the catheter 1 is designated as an insertion end 101. An air balloon 4 is fixedly connected around the catheter 1 near the insertion end 101. The width of the air balloon 4 at both ends is greater than the width in the middle, thus designing the air balloon 4 to be a shape that is wide at both ends and narrow in the middle. A ventilation tube 5 is fixedly connected to the air balloon 4. A cuff 6 is fixedly connected to the end of the ventilation tube 5 away from the air balloon 4. A second connector 7 that communicates with the ventilation tube 5 is fixedly connected to the cuff 6.

[0022] Compared with existing technologies, the expandable stoma cuff catheter provided by this utility model has two advantages. First, by wrapping and fixing the cuff around the catheter near the insertion end, and with the width at both ends of the cuff being greater than the width in the middle, the cuff is designed as a concave structure that is wider at both ends and narrower in the middle. This increases the contact area with the stoma, effectively improving its fixation within the patient's airway and preventing slippage or aspiration due to increased sputum or patient movement, thus improving safety during respiration. Second, by fixing an intubation tube to one end of the catheter, and fixing a first connector connected to the catheter at the outer end of the intubation tube, one end of the catheter can be cut according to actual needs, and then the intubation tube with the first connector fixedly connected can be fixedly inserted into the catheter. That is, the length of the catheter can be cut according to actual needs, thereby reducing the space occupied by the catheter in the airway, facilitating the drainage of sputum, and simplifying the operation.

[0023] As a specific embodiment, the catheter 1 is made of medical-grade polyvinyl chloride, which is favored due to its non-toxic, corrosion-resistant, waterproof, wear-resistant, high-temperature resistant, and easy-to-process properties. Furthermore, its excellent transparency makes it easy to observe the gas delivery within the tube. The airbag 4 is made of medical-grade silicone, which has good biocompatibility, is non-irritating, non-toxic, non-allergenic, and causes minimal rejection by the body. It also possesses good physicochemical properties, maintaining its original elasticity and softness during contact with body fluids and tissues, and is not degraded. It is a relatively stable inert material, easy to process and mold, and therefore very suitable for use in this application.

[0024] For a specific embodiment, please refer to Figure 1 As shown, the catheter 1 is provided with a depth mark 8 and a plurality of length marks 9. Thus, when the insertion end 101 of the catheter 1 is inserted into the patient's airway, the depth of insertion of the catheter 1 can be observed and determined by the depth mark 8, and the actual required length of the catheter 1 after being cut can be observed by setting the plurality of length marks 9.

[0025] For a specific embodiment, please refer to Figure 1 and Figure 2 As shown, the insertion end 101 is a beveled incision, which facilitates insertion into the patient's airway; the catheter 1 inside the beveled incision is provided with a Murphy hole 102, so that ventilation can be maintained through the Murphy hole 102 when the beveled incision is in close contact with the airway wall or when it is blocked for other reasons.

[0026] For a specific embodiment, please refer to Figure 1 As shown, the airbag 4 is fixedly connected to the conduit 1 between the Murphy orifice 102 and the depth mark 8, thereby allowing the airbag 4 to make good contact with the stoma and be fixed at the stoma.

[0027] For a specific embodiment, please refer to Figure 1 , Figure 3 and Figure 4 As shown, the diameter of the first connector 3 is larger than the diameter of the insertion tube 2. The insertion tube 2 is fixedly inserted into the inside of the catheter 1, which can effectively ensure the airtightness of the connection between the first connector 3 and the catheter 1 and prevent air leakage.

[0028] As a specific embodiment, the cuff 6 is provided with a one-way valve, which can prevent the gas entering the ventilation tube 5 through the second connector 7 from returning; the diameter of the ventilation tube 5 is smaller than the diameter of the catheter 1, which can ensure that the catheter 1 can be smoothly inserted into the patient's airway.

[0029] To better understand the expandable stoma balloon catheter provided by this utility model, its working principle will be briefly explained below: During operation, firstly, select an appropriate balloon 2 and catheter 1 according to the patient's age, weight, and airway size. At this time, one end of the catheter 1 can be cut off. Then, insert the cannula 2 into the catheter 1 and fix it. Insert the insertion end 101 of the catheter 1 into the patient's airway through the nasal cavity or oral cavity. Determine the insertion depth of the catheter 1 by using the depth mark 8. Then, connect the external inflation device to the second connector 7, and inject an appropriate amount of gas into the balloon 4 through the cuff 6 from the ventilation tube 5 to expand the balloon 4 and fix it at the stoma. After determining the fixed state of the balloon 4, connect the first connector 3 to the external anesthesia machine to deliver anesthetic gas. After the anesthesia ends, deflate the balloon 4, and finally pull out the catheter 1.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
