A device for blocking and sealing tracheotomy patients

Abstract

The present invention discloses a device for blocking and sealing the tube of a tracheotomy patient, which relates to the field of medical devices and includes a catheter, wherein a tube holder is installed on the surface of the catheter, and a plug is provided inside the tube holder. The device and method for blocking and sealing the tube of a tracheotomy patient described in the present invention are provided with an extrusion cone, an extrusion rod and a movable rod. Since the shape of the rubber plug is adapted to the shape of the tube holder, catheters of generally large and small diameters are smaller than the size of the tube holder, it is possible to ensure that the end of the catheter is blocked. At this time, during the downward movement of the extrusion cone, its surface will continuously squeeze the extrusion rod, so that the extrusion rod drives the movable rod close to the inside of the catheter, and the extrusion plug will slowly rest against the inner wall of the catheter. The extrusion plug is made of nitrile rubber, which can ensure that there is sufficient friction between the extrusion plug and the catheter, thereby preventing the plug from falling off, ensuring the overall sealing, and adapting to different catheters at the same time.

Description

Technical Field

[0001] The present invention relates to the field of medical instruments, and in particular to a device for blocking and sealing the tracheotomy tube of a patient. Background Art

[0002] Tracheotomy is a procedure that cuts open the cervical trachea and inserts a metal tracheal tube and a silicone tube. It is a common surgery to relieve dyspnea caused by laryngeal origin, respiratory dysfunction or retention of lower respiratory tract secretions. Long-term tracheotomy will increase or aggravate lung infection. Usually, sputum discharge can be promoted by turning over and patting the back. Therefore, timely sealing of the tube is required. It can not only reduce tracheal infection and prevent aspiration pneumonia caused by aspiration, but also restore and exercise the patient's language and swallowing functions as soon as possible.

[0003] There is no corresponding tube blocking device in clinical practice. Medical staff usually use rubber bottle stoppers to block the pipes. However, for different types of trachea, the size of the tube opening and the length of the tube are different. Therefore, different sizes of rubber are needed to block the tubes. At this time, multiple rubber stoppers are needed. Summary of the Invention

[0004] The main purpose of the present invention is to provide a device for blocking and sealing the tracheotomy tube of a patient, which can effectively solve the problems in the background technology.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a device for blocking and sealing the tube of a tracheotomy patient, comprising a catheter, a tube support is installed on the surface of the catheter, a plug is provided inside the tube support, a rubber plug of a matching shape is installed between the plug and the tube support, a moving rod is installed on the surface of the plug, a fixing assembly is installed between the moving rod and the plug, an extrusion cone is installed at the bottom of the moving rod, a rotating rod assembly is installed on the lower surface of the plug, the surface of the lower end of the extrusion cone abuts against the surface of the rotating rod assembly, an extrusion plug is installed on the surface of the rotating rod assembly, and the extrusion plug abuts against the inner wall of the catheter.

[0006] The rotating rod assembly includes a movable rod, a mounting bracket is installed on the lower surface of the plug, a rotating shaft is installed inside the mounting bracket, the movable rod is fixedly installed on the surface of the rotating shaft, an extrusion rod is installed on the surface of the movable rod, and the end of the extrusion rod is against the surface of the extrusion plug.

[0007] Circular grooves are provided on both sides of the interior of the mounting frame, and both ends of the rotating shaft are movably installed inside the circular grooves. A torsion spring is sleeved on the surface of the rotating shaft, one end of the torsion spring is installed inside the circular groove, and the other end of the torsion spring is installed on the surface of the movable rod.

[0008] The fixing assembly includes a first thread groove, which is opened in the middle of the plug. The surface of the moving rod is provided with a thread, and the moving rod is threadedly installed inside the first thread groove.

[0009] The movable rod includes a first rectangular rod and a second rectangular rod. The bottom of the first rectangular rod is provided with a second thread groove. The top of the second rectangular rod is provided with a thread rod. The thread rod is stuck in the second thread groove.

[0010] The end of the moving rod is provided with a knob horizontal plate.

[0011] There are multiple rotating rod assemblies arranged in an annular array on the surface of the extrusion cone.

[0012] A method for blocking and sealing a tracheotomy tube for a patient having tracheotomy, comprising the following steps: S1, aligning a rubber stopper with the interior of a tube holder and locking it against the inner wall of the tube holder, with the extrusion stopper and a rotating rod assembly positioned within the tube; and S2, fitting the stopper and the tube holder together and rotating the movable rod downward until the movable rod can no longer rotate.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. In the present invention, by providing an extrusion cone, an extrusion rod and a movable rod, since the shape of the rubber plug is adapted to the shape of the tube holder, generally, the diameters of catheters of different sizes are smaller than the size of the tube holder, so that the end of the catheter can be blocked. At this time, during the downward movement of the extrusion cone, its surface will continuously squeeze the extrusion rod, so that the extrusion rod drives the movable rod close to the inside of the catheter, and the extrusion plug will slowly rest against the inner wall of the catheter. The extrusion plug is made of nitrile rubber, which can ensure that there is sufficient friction between the extrusion plug and the catheter, thereby preventing the plug from falling off, ensuring the overall sealing, and adapting to different catheters.

[0015] 2. In the present invention, by setting a torsion spring, a rotating shaft and a circular groove, the initial action force of the torsion spring is to make the extrusion rod always press against the surface of the extrusion cone. At this time, when the plug is held horizontally, the torsion spring located on the surface of the lowest movable rod will rely on its own elastic force to offset the gravity of the movable rod itself, ensuring that all the extrusion rods can be placed just inside the catheter, making the plug more convenient to use.

[0016] 3. In the present invention, by providing a threaded rod and a second thread groove, the threaded rod is rotated so that its surface protrudes from a portion of the second thread groove, thereby indirectly increasing the length of the movable rod. When the extrusion plug is pressed against the inner wall of the catheter, the stability of the connection can be improved. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0025] like Figure 1-6 As shown, a device for blocking and sealing the tube of a tracheotomy patient comprises a catheter 1, a tube holder 2 is installed on the surface of the catheter 1, a plug 3 is provided inside the tube holder 2, the shape of the plug 3 is adapted to the internal shape of the tube holder 2, a rubber plug 4 of adapted shape is installed between the plug 3 and the tube holder 2, the rubber plug 4 is located inside the tube holder 2, a moving rod 5 is installed on the surface of the plug 3, a fixing assembly is installed between the moving rod 5 and the plug 3, an extrusion cone 6 is installed at the bottom of the moving rod 5, the lower end diameter of the extrusion cone 6 is smaller than the diameter of the upper end, a rotating rod assembly is installed on the lower surface of the plug 3, the surface of the lower end of the extrusion cone 6 abuts against the surface of the rotating rod assembly, an extrusion plug 7 is installed on the surface of the rotating rod assembly, and the extrusion plug 7 abuts against the inner wall of the catheter 1.

[0026] When in use, since the shape of the rubber stopper 4 is adapted to the shape of the tube holder 2, the diameter of the catheter 1 of generally large and small diameters is smaller than the size of the tube holder 2, so the end of the catheter 1 can be blocked. At this time, the moving rod 5 is moved so that the extrusion cone 6 is always against the surface of the rotating rod assembly until the rotating rod assembly is against the inside of the catheter 1. Regardless of the diameter and size of the catheter 1, the end can be blocked.

[0027] The rotating rod assembly includes a movable rod 8, which rotates along the diameter of the catheter 1. A mounting bracket 9 is installed on the lower surface of the plug 3, and a rotating shaft 10 is installed inside the mounting bracket 9. The movable rod 8 is fixedly mounted on the surface of the rotating shaft 10, and the rotating shaft 10 rotates on the surface of the mounting bracket 9. An extrusion rod 11 is installed on the surface of the movable rod 8, and the end of the extrusion rod 11 is against the surface of the extrusion plug 7.

[0028] Since the diameter of the lower end of the extrusion cone 6 is smaller than the diameter of the upper end, the surface of the extrusion cone 6 will continuously squeeze the extrusion rod 11 during the downward movement of the extrusion cone 6, so that the extrusion rod 11 drives the movable rod 8 close to the inside of the catheter 1, and the extrusion plug 7 will slowly rest against the inner wall of the catheter 1. The extrusion plug 7 is made of nitrile rubber, which can ensure that there is sufficient friction between the extrusion plug 7 and the catheter 1, thereby preventing the plug 3 from falling and ensuring the overall sealing.

[0029] Circular grooves 12 are provided on both sides of the interior of the mounting frame 9, and both ends of the rotating shaft 10 are movably mounted inside the circular grooves 12. A torsion spring 13 is sleeved on the surface of the rotating shaft 10, and one end of the torsion spring 13 is mounted inside the circular groove 12, and the other end of the torsion spring 13 is mounted on the surface of the movable rod 8. The initial action force of the torsion spring 13 is to make the extrusion rod 11 always press against the surface of the extrusion cone 6. At this time, when the plug 3 is held horizontally, the torsion spring 13 on the surface of the movable rod 8 at the bottom will rely on its own elastic force to offset the gravity of the movable rod 8 itself, ensuring that all the extrusion rods 11 can be just placed inside the catheter 1, making the plug 3 more convenient to use.

[0030] The fixing component includes a first thread groove 14, which is opened in the middle position of the plug 3. The surface of the moving rod 5 is provided with a thread, and the moving rod 5 is threadedly installed inside the first thread groove 14. During use, the moving rod 5 is rotated. During the rotation, the moving rod 5 will also move laterally. At the same time, in the absence of lateral external force, the moving rod 5 cooperates with the first thread groove 14 to have a certain fixing effect, thereby ensuring the stability of the seal.

[0031] The movable rod 8 includes a first rectangular rod 15 and a second rectangular rod 16. The cross-sections of the first rectangular rod 15 and the second rectangular rod 16 are both rectangular, which can make it easier to distinguish the positional relationship and ensure that the extrusion plug 7 is stably against the inside of the catheter 1. A second threaded groove 17 is provided at the bottom of the first rectangular rod 15, and a threaded rod 18 is installed at the top of the second rectangular rod 16. The threaded rod 18 is stuck in the inside of the second threaded groove 17. Due to different pipes, their lengths are different. In order to ensure the stability of the connection, for catheters 1 with longer pipe lengths, the threaded rod 18 can be rotated so that its surface protrudes from a part of the second threaded groove 17, thereby indirectly increasing the length of the movable rod 8.

[0032] A knob horizontal plate 19 is installed at the end of the moving rod 5. Rotating the knob horizontal plate 19 will drive the moving rod 5 to rotate.

[0033] There are multiple rotating rod assemblies arranged in an annular array on the surface of the extrusion cone 6 .

[0034] A method for blocking and sealing a tracheotomy tube for a patient undergoing tracheotomy, comprising the following steps: S1, aligning a rubber stopper 4 with the interior of a tube holder 2 and locking it against the inner wall of the tube holder 2, with an extrusion stopper 7 and a rotating rod assembly positioned within a catheter 1; S2, fitting the stopper 3 and the tube holder 2 together and rotating a moving rod 5 downward until the moving rod 5 can no longer rotate.

[0035] The cam 7 is pressed against the inner wall of the tube 1 and the cam 7 is pressed against the inner wall of the tube 1. When the cam 7 is pressed against the inner wall of the tube 1, the cam 7 and the movable rod 8 are pressed against the inner wall of the tube 1. When the cam 7 is pressed against the inner wall of the tube 1, the cam 7 is ...
