Technical Field

[0001] The utility model relates to the technical field of medical devices, specifically a built-in plugging device for tracheotomy Background Art

[0002] When the patient cannot breathe, a tube needs to be cut in the patient's neck and breathing is assisted through the trachea. There are metal tracheas and plastic tracheas. The metal trachea is for long-term use and has calibers of 8mm, 9mm, 10mm and 11mm, which will be used according to the patient's condition. The plastic trachea is used for emergency rescue and is generally disposable. Tracheotomy is a common surgery to cut open the cervical trachea and insert a metal or disposable plastic trumpet-mouthed cannula to relieve laryngeal dyspnea, respiratory dysfunction or dyspnea caused by retention of lower respiratory tract secretions. The metal trachea is for long-term use and has calibers of 8mm, 9mm, 10mm and 11mm, which will be used according to the patient's condition.

[0023] To facilitate the solution of the problem, the embodiment of the present invention provides a built-in plug device for tracheotomy. The technical solutions in the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] Example 1, as Figures 1 to 5As shown, this embodiment provides a built-in plug device for tracheotomy, including a mounting plate 1, a closed plug assembly arranged at the bottom of the mounting plate 1 and a sealing detection assembly arranged at one end of the mounting plate 1, the closed plug assembly includes a bell-mouth sleeve 2 and an airbag 301 connected to the inside of the bell-mouth sleeve 2, one end of the airbag 301 is connected to a catheter 302, one end of the catheter 302 is connected to a joint 303, one end of the joint 303 is connected to an inflator 305, the airbag 301 is inflated and deflated by the inflator 305, the sealing detection assembly includes a sleeve 402 detachably connected to the surface of the airbag 301, a connecting hole 403 is opened inside the sleeve 402, there are multiple connecting holes 403, a fiber line 404 is movably connected inside the connecting hole 403, and the sealing effect is detected by the fiber line 404.

[0025] Embodiment 2. In addition to all the technical features of embodiment 1, this embodiment also includes: the sealing plug assembly also includes a one-way valve 304 that is cooperatively connected to one end of the connector 303, one end of the one-way valve 304 is cooperatively connected to the inside of the inflator 305, and a switch 306 is cooperatively connected to the surface of the inflator 305. The power supply of the inflator 305 is controlled by the switch 306. The switch 306 makes it easy for users to control the inflator 305 and to inflate the airbag 301. The one-way valve 304 prevents leakage of the airbag 301, which may cause leakage of the seal.

[0026] The small diameter tube mouth of the bell-mouth sleeve 2 is clamped in the through hole opened at the center of the mounting plate 1, and the sleeve 402 is clamped in the tube of the bell-mouth sleeve 2. The large diameter tube mouth of the bell-mouth sleeve 2 can be clamped and sleeved on the tube mouth of the patient's tracheal cannula, and then the airbag 301 is inflated to seal the inner wall of the bell-mouth sleeve 2, that is, the tracheal cannula in the patient's throat can be hiddenly blocked. The sealing detection component also includes a valve control button 401 connected to the surface of the inflator 305. One end of the valve control button 401 is electrically connected to the power input end of the one-way valve 304. The one-way valve 304 is controlled by the valve control button 401 to facilitate the deflation of the gas inside the airbag 301, which is convenient for extraction and use.

[0027] The surface of the sleeve 402 is connected to the inner wall surface of the bell-mouth sleeve 2. The sleeve 402 is made of soft rubber. The surface of the inflator 305 is connected to the wire 5. The ring is used to increase the detectability of the closure of the airbag 301, and the inflator 305 is powered by the wire 5.

[0028] Working principle: After the user installs the mounting plate 1 and the bell-mouth sleeve 2 in the predetermined position, the user turns on the power supply of the inflator 305 through the switch 306. The inflator 305 transmits the gas to the inside of the conduit 302 through the one-way valve 304, and fills the gas into the airbag 301 through the conduit 302, and inflates the airbag 301. After the airbag 301 expands, it expands and seals the space inside the bell-mouth sleeve 2, and seals the space inside the bell-mouth sleeve 2. At this time, after the airbag 301 reaches the predetermined expansion size and seals the inside of the bell-mouth sleeve 2, the one-way valve 304 is used to prevent gas backflow, so that the airbag 301 remains inflated, and the inside of the bell-mouth sleeve 2 is kept sealed. Then, when the bell-mouth sleeve plugging device is in use, it has a plugging device that can adapt to various structures of trachea, so that the trachea can be blocked and leakage is not likely to occur. In this case, when it is necessary to test the sealing condition of the blockage, the airbag 301 expands and drives the sleeve 402 connected to its surface to open, so that the sleeve 402 fits and squeezes the inner wall of the bell-mouth sleeve 2, and the multiple connection holes 403 opened inside the sleeve 402 connect the fiber line 404. When the sleeve 402 expands and squeezes, the space on the inner wall of the connection hole 403 is squeezed, thereby squeezing the fiber line 404. The user can pull the fiber line 404 to understand the sealing status. If the fiber line 404 can be pulled, it means that the blockage is not in place, and if it is in place, it is the opposite. Its structure is simple and easy to detect. Then, the plugging device of the bell-mouth sleeve has a detection device after the inside of its trachea is blocked when it is used, thereby improving the overall leakage detection performance, making it less likely to have a blockage that is not in place, and reducing unnecessary medical problems.
