Description

Technical Field

[0001] The present application relates to the technical field of medical auxiliary devices, and in particular to a drainage tube joint fixing device for a three-chamber chest closed drainage bottle. Background Art

[0002] Currently, when three-chamber chest closed drainage bottles are installed in hospitals, a gap exists between the drainage tube and the chest bottle joint. This allows the drainage tube to move freely, causing the tube to rotate with the patient's daily activities. This often causes the chest tube to twist and bend as the patient moves with the drainage tube, resulting in poor drainage and affecting the patient's postoperative recovery. To address this issue, the present invention proposes a drainage tube joint fixing device for a three-chamber chest closed drainage bottle. Utility Model Content

[0003] An embodiment of the present application provides a drainage tube joint fixing device for a three-chamber chest closed drainage bottle, which can cooperate with the connecting tube to lock and fix the drainage tube to prevent it from moving and causing chest tube blockage.

[0004] In view of this, the present application provides a drainage tube joint fixing device for a three-chamber chest closed drainage bottle, including: an extrusion piece for filling between the drainage tube and the connecting tube, and the extrusion piece is provided with a first bayonet for fitting with the curvature of the outer peripheral surface of the drainage tube.

[0005] Optionally, the extrusion piece has a C-shaped structure.

[0006] Optionally, the width of the extruded piece is 7-8 mm.

[0007] Optionally, an anti-slip structure is provided on the first bayonet.

[0008] Optionally, a second bayonet for fitting with the curvature of the outer peripheral surface of the connecting pipe is provided on a side of the extrusion piece away from the first bayonet.

[0009] Optionally, an anti-slip structure is provided on the second bayonet.

[0010] Optionally, the anti-slip structure is a hemispherical raised structure.

[0011] Optionally, the extrusion piece has a double C-shaped structure.

[0012] Optionally, the extrusion member is made of elastic material.

[0013] Optionally, the elastic material is rubber or silicone.

[0014] As can be seen from the above technical solution, the embodiments of the present application have the following advantages: the drainage tube connector fixing device for a three-chamber closed chest drainage bottle includes an extrusion member for filling between the drainage tube and the connecting tube, and the extrusion member is provided with a first clip for conforming to the curvature of the outer circumference of the drainage tube. During use, by installing the first clip between the drainage tube and the connecting tube with the first clip facing the drainage tube, the gap between the drainage tube and the connecting tube can be completely filled, and the gap between the drainage tube and the chest bottle connector can be compressed to secure the drainage tube and prevent the tube from moving and causing chest tube blockage.

[0021] In order to help those skilled in the art better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of this application.

[0022] In the description of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate the description of this application and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0023] Unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be interpreted broadly. For example, they can refer to fixed, removable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this application.

[0024] The inventors discovered that there is a small distance between the drainage tube interface and the connecting tube interface of the three-chamber chest closed drainage bottle. After the drainage tube and the connecting tube are installed, there is a distance of about 5-6 mm between the two. After using external force to fill the gap between the drainage tube and the connecting tube with an object of similar width, the drainage tube will be stuck and unable to rotate.

[0025] This application provides an embodiment of a drainage tube joint fixing device for a three-chamber chest closed drainage bottle. Figure 1 .

[0026] The drainage tube joint fixing device for a three-chamber chest closed drainage bottle in this embodiment includes: an extrusion piece 1 for filling between the drainage tube and the connecting tube, and a first bayonet 11 is provided on the extrusion piece 1 for fitting with the curvature of the outer peripheral surface of the drainage tube.

[0027] It should be noted that when in use, by installing the first bayonet 11 between the drainage tube and the connecting tube toward the drainage tube, the gap between the drainage tube and the connecting tube can be completely filled, and the gap between the drainage tube and the chest bottle connector can be compressed to fix the drainage tube and prevent it from moving and causing chest tube blockage.

[0028] The above is the embodiment of the present invention provided by the embodiment of a drainage tube joint fixing device for a three-chamber chest cavity closed drainage bottle. The following is the embodiment of the present invention provided by the embodiment of a drainage tube joint fixing device for a three-chamber chest cavity closed drainage bottle. For details, please refer to Figures 1 to 4 .

[0029] The drainage tube joint fixing device for a three-chamber chest closed drainage bottle in this embodiment includes: an extrusion piece 1 for filling between the drainage tube and the connecting tube, and a first bayonet 11 is provided on the extrusion piece 1 for fitting with the curvature of the outer peripheral surface of the drainage tube.

[0030] Understandably, if a patient's chest tube rotates at the connection between the tube and the three-chamber chest tube during daily activities, causing twisting and kinking, the current clinical solution is for a nurse to rotate the tube against the direction of the twisting until the tube is straightened and untwisted. However, this can only be addressed promptly during a nurse's shift check. If the patient moves after the nurse has checked the tube, the tube may twist again, often unnoticed by the patient themselves. Family members and nurses don't routinely pull up the patient's clothing to check for blockage. Most cases are discovered and addressed only during the next shift check, or after the patient has already experienced symptoms such as chest tightness, shortness of breath, and difficulty breathing due to the blockage. Compared to existing solutions, the present drainage tube connector fixing device, once installed (by locking the gap between the drainage tube and the connecting tube), addresses the problem of rotation caused by the large range of motion at the connection between the drainage tube and the chest tube, significantly reducing the likelihood of chest tube twisting and blockage.

[0031] Specifically, such as Figure 2 As shown, the extrusion piece 1 can be in a C-shaped structure, which can fit the curvature of the drainage tube while blocking the gap between the drainage tube and the connecting tube, making it easy to disassemble.

[0032] The height of the extruded part 1 may be 15-16 mm, the width may be 7-8 mm, the inner diameter may be 12-13 mm, and the outer diameter may be 26-29 mm.

[0033] It can be understood that the width of the extrusion piece 1 is slightly larger than the gap between the drainage tube and the connecting tube, so that the extrusion piece 1 can be stuck between the drainage tube and the connecting tube to fix the drainage tube.

[0034] The first bayonet 11 may be provided with an anti-slip structure to increase friction and further prevent the drainage tube from rotating.

[0035] A second bayonet 12 for fitting with the curvature of the outer peripheral surface of the connecting pipe may be provided on a side of the extrusion piece 1 away from the first bayonet 11 .

[0036] The second bayonet 12 may be provided with an anti-slip structure, which can increase the friction between the contact surface of the extrusion piece 1 and the connecting pipe, and further improve the fixing effect.

[0037] Specifically, the anti-slip structure may be a hemispherical protrusion structure 13 , which is evenly distributed on the first bayonet 11 and the second bayonet 12 , and serves to increase friction and prevent the drainage tube from rotating.

[0038] like Figure 3 As shown, the extruded part 1 has a double C-shaped structure.

[0039] The extrusion member 1 is made of an elastic material, specifically, rubber or silicone.

[0040] As described above, the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
