Description

Technical Field

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

[0002] Tracheotomy is a commonly used rescue and treatment method in clinical practice. Usually, a "tracheotomy tube" is used to perform oxygen inhalation and sputum suction on tracheotomy patients. Before extubation, it is usually necessary to try to block the tube to determine whether the patient can breathe independently. For some patients who are not suitable for complete tube blocking, it is necessary to transition from a semi-blocked state to a completely blocked state.

[0003] A blocking device for a tracheal tube is disclosed in Chinese utility model patent application No. CN204502011U; full blocking and semi-blocking operations of the tracheal tube are completed by a second plug body and a first plug body embedded in the second plug body, and the plug body made of rubber material ensures the sealing effect; when the tracheal tube is fully blocked and plate-blocked, the second plug body needs to be embedded in the trachea to complete semi-blocking, and the first plug body needs to be embedded in the vent to complete full blocking; the device is inconvenient to fix during use, and when the patient chokes and coughs, the first plug body is easily washed away, and it is not convenient to adjust the blockage degree of the trachea in real time; therefore, we propose a tracheal tube blocking device to solve the above problems. Utility Model Content

[0004] The utility model aims to solve the shortcomings of the background technology and proposes a tracheal tube blocking device.

[0005] To achieve the above objectives, the technical solution adopted by the utility model is: a tracheal tube blocking device, comprising: an air outlet pipe, a mounting seat, a rubber sleeve, a blocking seat, a support rod, a circular seat, a threaded hole, a threaded rod, a knob, and a blocking head. The mounting seat is fixedly installed on the left side of the air outlet pipe, the rubber sleeve is fixedly installed on the left side of the mounting seat, the blocking seat is fixedly installed on the right side of the air outlet pipe, a plurality of support rods are fixedly installed on the right edge of the blocking seat, a circular seat is fixedly installed on the right side of the support rod, a threaded hole is provided in the middle of the circular seat, a threaded rod is threadedly connected inside the threaded hole, a knob is fixedly installed on the right side of the threaded rod, a blocking head is fixedly installed on the left side of the threaded rod, and the blocking head is movably installed inside the blocking seat.

[0006] Preferably, there is an equidistant spacing between the mounting seat and the rubber sleeve.

[0007] Preferably, the plugging head and the plugging seat are both arranged in a conical structure, and the plugging head is adapted to the inside of the plugging seat.

[0008] Preferably, the blocking seat is made of a transparent plastic structure.

[0009] Preferably, the plug is made of rubber.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] (1) By rotating the knob, the threaded rod can be driven to rotate inside the threaded hole, so that the threaded rod can synchronously drive the plugging head to rotate and move. When the plugging head is completely moved into the plugging seat, the air outlet pipe can be completely blocked, and the trachea can be blocked synchronously. When the plugging head is slowly moved out from the plugging seat, there will be an equidistant gap between the plugging head and the plugging seat, so that the gas can flow out from the gap, thereby semi-blocking the air outlet pipe. The more the plugging head is moved out, the larger the distance between the plugging head and the plugging seat will be. Therefore, the blockage degree of the air outlet pipe can be adjusted according to the patient's comfort level, and the blockage degree of the trachea can be adjusted synchronously, so that it is easy to adjust during use.

[0012] (2) The mounting seat can be embedded in the trachea, so that the outlet pipe is easy to install on the trachea, and the rubber sleeve can be closely attached to the surface of the trachea, thereby improving the sealing between the mounting seat and the trachea.

[0020] like Figure 1-5The tracheal tube blocking device shown comprises: an air outlet pipe 1, a mounting seat 2, a rubber sleeve 3, a blocking seat 4, a support rod 5, a circular seat 6, a threaded hole 7, a threaded rod 8, a knob 9, and a blocking head 10. The mounting seat 2 is fixedly installed on the left side of the air outlet pipe 1, the rubber sleeve 3 is fixedly installed on the left side of the mounting seat 1, the blocking seat 4 is fixedly installed on the right side of the air outlet pipe 1, a plurality of support rods 5 are fixedly installed on the right edge of the blocking seat 4, a circular seat 6 is fixedly installed on the right side of the support rod 5, a threaded hole 7 is provided in the middle part of the circular seat 6, a threaded rod 8 is threadedly connected inside the threaded hole 7, a knob 9 is fixedly installed on the right side of the threaded rod 8, a blocking head 10 is fixedly installed on the left side of the threaded rod 8, and the blocking head 10 is movably installed inside the blocking seat 4.

[0021] In this embodiment, there is an equidistant distance between the mounting seat 2 and the rubber sleeve 3 .

[0022] During specific use, the mounting base 2 can be embedded in the trachea, so that the air outlet pipe 1 is easy to install on the trachea, and the rubber sleeve 3 can be closely attached to the surface of the trachea, thereby improving the sealing between the mounting base 2 and the trachea.

[0023] In this embodiment, the plugging head 10 and the plugging seat 4 are both arranged in a conical structure, and the plugging head 10 is adapted to the inside of the plugging seat 4 .

[0024] During specific use, the threaded rod 8 can be driven to rotate inside the threaded hole 8 by rotating the knob 9, so that the threaded rod 8 can synchronously drive the plugging head 10 to rotate and move. When the plugging head 10 is completely moved to the inside of the plugging seat 4, the air outlet pipe 1 can be completely blocked, and the trachea can be blocked synchronously. When the plugging head 10 is slowly moved out from the inside of the plugging seat 4, there will be an equidistant gap between the plugging head 10 and the plugging seat 4, so that the gas can flow out from the gap, thereby semi-blocking the air outlet pipe 1, and the more the plugging head 10 is moved out, the larger the distance between the plugging head 10 and the plugging seat 4 will be, so that the blockage degree of the air outlet pipe 1 can be adjusted according to the patient's comfort level, and the blockage degree of the trachea can be adjusted synchronously, so that it is convenient to adjust during use.

[0025] In this embodiment, the blocking seat 4 is made of a transparent plastic structure.

[0026] During specific use, the plugging seat 4 is made of a transparent plastic structure, so that the distance between the plugging head 10 and the plugging seat 4 can be easily observed.

[0027] In this embodiment, the plug 10 is made of rubber.

[0028] During specific use, the plugging head 10 is made of rubber material, so when the plugging head 10 is completely moved into the plugging seat 4, the plugging head 10 can be tightly attached to the inside of the plugging seat 4 due to its own elasticity, thereby improving the sealing between the plugging head 10 and the plugging seat 4.

[0029] The working principle of the tracheal tube blocking device mentioned in the utility model is as follows:

[0030] When in use, the mounting seat 2 can be embedded in the trachea, so that the outlet pipe 1 is easy to install on the trachea, and the rubber sleeve 3 can be closely attached to the surface of the trachea, thereby improving the sealing between the mounting seat 2 and the trachea;

[0031] Then, by rotating the knob 9, the threaded rod 8 can be driven to rotate inside the threaded hole 8, so that the threaded rod 8 can synchronously drive the plugging head 10 to rotate and move. When the plugging head 10 is completely moved to the inside of the plugging seat 4, the air outlet pipe 1 can be completely blocked, and the trachea can be blocked synchronously. When the plugging head 10 is slowly moved out from the inside of the plugging seat 4, there will be an equidistant gap between the plugging head 10 and the plugging seat 4, so that the gas can flow out from the gap, thereby semi-blocking the air outlet pipe 1, and the more the plugging head 10 is moved out, the larger the distance between the plugging head 10 and the plugging seat 4 will be, so that the blockage degree of the air outlet pipe 1 can be adjusted according to the patient's comfort level, and the blockage degree of the trachea can be adjusted synchronously, so that it is convenient to adjust during use.
