Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to a tracheotomy tube blocking device. Background Art

[0002] In recent years, tracheotomy has been widely used clinically and has become a well-known primary rescue measure for airway obstruction and dyspnea. Compared to disposable plastic endotracheal tubes, metal endotracheal tubes offer advantages such as a thinner tube diameter, a larger gap between the outer tube and the tracheal wall, a lack of a cuff, a smooth tube wall, reduced adhesion to the tracheal wall, and easier coughing up of sputum after tube obstruction. These advantages make them suitable for patients who require medium- to long-term endotracheal tube use and those recovering from spontaneous breathing.

[0003] The following problems exist in current clinical work:

[0004] The outer opening of the tracheostomy tube is sealed with a simple silicone cap, which is snapped on to the tube. It is easy to loosen or fall off due to pressure and vibration during breathing or daily life, resulting in poor sealing of the tube plugger. Frequent loosening and falling of the tube plugger will cause its inner side to be exposed to the air, further making it difficult to ensure the sanitary conditions of the tube and cap. In addition, when the patient takes off the tube plugger cap with difficulty breathing, the removed cap is easy to be lost and contaminated, and ordinary plugs and caps can only achieve full blocking or full opening after disassembly, which is of no help for recovery training. The above defects are problems that need to be urgently solved by technical personnel in this field. Utility Model Content

[0005] In view of the prior art, the purpose of the present invention is to provide.

[0006] In order to achieve the above purpose, the technical solution adopted by the present invention is: a tracheostomy tube plugging device, including: a silicone collar seat, the inner side of the silicone collar seat fits the inner tube of the throat tracheostomy tube and extends into the incision from the inside of the silicone collar seat, and the external blocking tube opening of the tracheostomy tube is exposed on the outside of the silicone collar seat; a blocking cap, threadedly connected to the blocking tube opening, used to block and seal it, and an elastic part and an abutting sealing plate are provided in the blocking cap; an accommodating column, arranged on the side of the silicone collar seat opposite to the blocking tube opening, used for placing the blocking cap.

[0007] As a further arrangement of the above scheme, the pipe blocking cap includes a full blocker and a trainer, and the trainer is provided with a plurality of air vents on the side wall relative to the abutting sealing plate and the movable elastic part, and the abutting sealing plate arranged on the trainer is provided with an air flow channel connected to the inner cavity of the pipe blocking cap.

[0008] As a further configuration of the above scheme, a silicone layer is provided on one side of the abutting sealing plate abutting against the end face of the pipe blocking port, and the other side of the abutting sealing plate abuts against an elastic member, which is used to elastically push it toward the pipe blocking port.

[0009] As a further configuration of the above scheme, the pipe blocking cap includes a front tube and a threaded rear sleeve, the opening of the front tube facing the pipe blocking port is smaller than the diameter of its internal cavity, and the diameter of the opening is smaller than the diameter of the abutting sealing plate.

[0010] As a further configuration of the above solution, the threads of the accommodating column and the pipe blocking port are configured in the same manner, and the pipe blocking cap has an internal thread that matches the internal thread for threaded connection.

[0011] As a further configuration of the above solution, an anti-slip groove is further provided on the end surface of the pipe blocking port, and the anti-slip groove is a shallow annular groove with a notch in the circumferential direction.

[0012] As a further configuration of the above solution, the pipe blocking cap is provided with an anti-lost rope, and the silicone collar seat is provided with a rope hole and a strap hole for the collar strap.

[0013] Beneficial effect: The utility model of the tracheotomy tube plugging device improves the design of the plugging cap.

[0014] 1. A plug cap structure with a threaded connection to the tracheostomy tube is provided, and a retractable elastic abutment plate is provided in the inner hole of the plug cap. The abutment between the abutment plate and the end of the tracheostomy tube enhances the sealing effect of the simple plug cap thread locking;

[0015] 2.

Part of the silicone material deforms and embeds into the shallow groove, which enhances the friction and makes the pipe cap less likely to rotate and loosen under normal shaking and collision, thereby improving its usability.

[0016] 3. Compared with the existing complex pipe plugging devices, the pipe plugging device of this embodiment can be disassembled by simply rotating the thread, which is very convenient for disassembly, cleaning and disinfection, and is easy for users to operate;

DETAILED DESCRIPTION

[0023] In order to more clearly understand the above-mentioned objectives, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0024] like Figure 1-4 The tracheostomy tube plugging device shown includes: a silicone collar seat 1, the inner side of the silicone collar seat 1 fits the inner tube of the pharyngeal tracheostomy tube 2 and extends into the incision from the inner side of the silicone collar seat 1, and the external blocking tube opening 3 of the tracheostomy tube 2 is exposed on the outside of the silicone collar seat 1; a blocking cap 4, threadedly connected to the blocking tube opening 3, used to block and block it, and an elastic member 41 and an abutting sealing plate 42 are provided in the blocking cap 4; an accommodating column 5, arranged on the side of the silicone collar seat 1 opposite to the blocking tube opening 3, used for placing the blocking cap 4.

[0025] As a further arrangement of the above scheme, the pipe blocking cap 4 includes a full blocker 45 and a trainer 46. The trainer 46 is provided with a plurality of air vents 44 on the side wall relative to the abutting sealing plate 42 and the movable elastic member 41. The abutting sealing plate 42 arranged on the trainer 46 has an air flow channel 43 connected to the inner cavity of the pipe blocking cap 4.

[0026] As a further arrangement of the above scheme, a silicone layer 47 is provided on the side of the abutting sealing plate 42 abutting against the end face of the pipe blocking port 3, and the other side of the abutting sealing plate 42 abuts against the elastic member 41, which is used to elastically push it toward the pipe blocking port 3.

[0027] As a further arrangement of the above scheme, the pipe blocking cap 4 includes a front tube 49 and a threadedly locked rear sleeve 48, the opening 491 of the front tube 49 facing the pipe blocking port 3 is smaller than the diameter of its internal cavity 492, and the diameter of the opening 491 is smaller than the diameter of the abutting sealing plate 42.

[0028] As a further configuration of the above solution, the threads of the accommodating column 5 and the pipe blocking port 3 are configured in the same manner, and the pipe blocking cap 4 has an internal thread that matches and is threadedly connected thereto.

[0029] As a further configuration of the above solution, an anti-slip groove 6 is further provided on the end surface of the pipe blocking port 3 , and the anti-slip groove 6 is a shallow annular groove with a notch in the circumferential direction.

[0030] As a further configuration of the above solution, the pipe blocking cap 4 is provided with an anti-lost rope 8, and the silicone collar seat 1 is provided with a rope hole 81 and a strap hole 10 for the collar strap.

[0031] The tracheotomy tube blocking device of this embodiment is as follows Figure 1-4 The device shown is mainly composed of a silicone collar seat 1 with a cannula and a tube blocking cap 4. The unique design in this embodiment is that a accommodating column 5 is also provided on one side of the main tracheostomy cannula 2. The purpose of providing the accommodating column 5 is to place the tube blocking cap 4 for disassembly by thread, and based on the structural setting of the tube blocking cap 4 itself in this embodiment, an abutting sealing plate 42 with an elastic member 41 is provided inside it. When in use, the abutting sealing plate 42 abuts against the end of the tracheostomy cannula 2 based on the elastic force of the elastic member 41. The silicone layer 47 provided on the end face of the abutting sealing plate 42 has a certain elasticity. When abutting, the elastic force of the elastic member 41 compresses to form a certain deformation to improve the sealing, and the elasticity improved by the elastic member 41 enhances the friction force. Compared with the prior art, the tube blocking cap 4 is avoided due to various actions when worn, which causes the threads of the tube blocking cap 4 and the outer wall of the tracheostomy cannula 2 to become loose, thereby avoiding the problem of loosening and falling off.

[0032] In addition, the tube blocking cap 4 of this embodiment is provided with a full blocker 45 and a trainer 46. The full blocker 45 is used to completely close the tracheostomy tube 2. However, when the patient is in the recovery period and needs to gradually adapt to normal breathing, and it is not convenient to open it fully directly, the full blocker 45 can be replaced on the accommodating column 5, and the trainer 46 can be screwed onto the tracheostomy tube 2. By continuously tightening the thread, the axial movement of the abutting sealing plate 42 can be controlled, thereby adjusting the number of holes on the outer wall of the trainer 46 that are connected to the tracheostomy tube 2 through the airflow channel 43, thereby realizing the adjustment of the airflow volume and achieving the purpose of gradual adaptation.

[0033] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
