Description

Technical Field

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

[0002] During clinical tracheotomy and intubation, the tube needs to be sealed gradually after the cause of the patient's illness is resolved, and the tube can be removed only after the patient has fully adapted. Currently, wooden plugs, cotton balls and other devices are usually used with the help of tape to seal the tube, which is more troublesome to operate, the seal is not tight, and there is a risk of debris entering the patient's body through the tube.

[0003] During clinical occlusion, complete occlusion cannot be performed in one go, so traditional methods are used, which requires frequent operations. Utility Model Content

[0004] The technical problem to be solved by the utility model is that: currently, wooden plugs, cotton balls and other devices are usually used to seal the tube with the help of tape, which is troublesome to operate and the seal is not tight. There is a risk of debris entering the patient's body through the cannula, and in order to control the size of the blocked air intake, continuous adjustment is required, which is relatively cumbersome.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A tracheal tube blocking device comprises a blocking seat, a through hole is provided in the middle of the blocking seat along the axis direction thereof, and an internal thread is provided in the through hole;

[0007] An adjusting knob with an inverted "T"-shaped cross section is arranged above the sealing plug seat, and the outer surface of the adjusting knob is threadedly connected with the through hole;

[0008] A ventilation blind hole is provided at the middle position of the top of the adjusting knob, and a lower exhaust layer, a middle exhaust layer and an upper exhaust layer are sequentially provided on the outer surface of the adjusting knob from the bottom to the top;

[0009] The lower exhaust layer, the middle exhaust layer and the upper exhaust layer are all composed of a plurality of exhaust holes connected with the ventilation blind hole, and the exhaust holes in the lower exhaust layer, the middle exhaust layer and the upper exhaust layer are all arranged at equal angles on the outer surface of the adjusting knob.

[0010] Furthermore, the number of exhaust holes in the lower exhaust layer, the middle exhaust layer and the upper exhaust layer decreases successively.

[0011] Furthermore, a plug hole connected to the blind vent hole is provided at the top of the adjusting knob, and a plug body is embedded in the plug hole.

[0012] Working principle and beneficial effects: The sealing plug is connected to the exposed end of the cannula, and then the adjusting knob is slowly screwed into the through hole on the sealing plug. Due to the special setting of the exhaust hole on the adjusting knob, as the adjusting knob is slowly screwed into the through hole of the sealing plug, the exhaust volume gradually decreases, and finally complete sealing is achieved. The structure is simple and easy to operate. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The present invention can be better understood according to the following embodiments.

[0019] The structures, proportions, sizes, etc. illustrated in the drawings of the specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the utility model, so they have no substantial technical significance. Any modification of the structure, change of the proportion relationship or adjustment of the size, without affecting the effect and purpose that can be achieved by the utility model, should still fall within the scope of the technical content disclosed by the utility model. At the same time, the terms such as "upper", "lower", "front", "back", "middle" and so on quoted in this specification are only for the convenience of description, and are not used to limit the scope of the implementation of the utility model. The change or adjustment of their relative relationship should also be regarded as the scope of the implementation of the utility model without substantial change of the technical content.

[0020] like Figure 1-4 As shown,

[0021] Example 1

[0022] A tracheal intubation blocking device comprises a blocking seat 1, a through hole is opened in the middle of the blocking seat 1 along its central axis, an internal thread is arranged in the through hole, an adjusting knob 2 with an inverted "T"-shaped cross-section is arranged above the blocking seat 1, the outer surface of the adjusting knob 2 is threadedly connected to the through hole, a ventilation blind hole is opened in the middle position of the top of the adjusting knob 2, and the outer surface of the adjusting knob 2 is sequentially provided with a lower exhaust layer, a middle exhaust layer and an upper exhaust layer from the bottom to the top, the lower exhaust layer, the middle exhaust layer and the upper exhaust layer are all composed of a plurality of exhaust holes 3 connected with the ventilation blind hole, and the exhaust holes in the lower exhaust layer, the middle exhaust layer and the upper exhaust layer are all arranged at equal angles on the outer surface of the adjusting knob 2.

[0023] When in use, first connect the sealing plug 1 to the exposed end of the insertion tube. The internal thread of the through hole on its inner surface is convenient for embedding and ensuring the tightness of the connection. After the sealing plug 1 is connected to the insertion tube, slowly screw the adjusting knob 2 into the through hole on the sealing plug 1. Due to the special setting of the exhaust hole 3 on the adjusting knob 2, as the adjusting knob 2 is slowly screwed into the through hole of the sealing plug 1, the exhaust volume gradually decreases, and finally complete sealing is achieved.

[0024] The structure is simple and easy to operate, and can slowly block the air intake to meet clinical needs. The number of exhaust holes 2 in the lower exhaust layer, the middle exhaust layer, and the upper exhaust layer is reduced successively to ensure effective regulation of the air intake and exhaust volumes.

[0025] In order to ensure that the installation of the device does not cause discomfort in the early stage, embodiment 2 is provided, in which a plug hole connected to the ventilation blind hole is provided at the top of the adjusting knob 2, and a plug body 4 is embedded in the plug hole.

[0026] That is, when the adjusting knob 2 is screwed in in Example 1, the plug body 4 is merged into the plug hole, and after the adjusting knob 2 is adjusted to a proper position (the exhaust hole 3 is not blocked), the plug body 4 is then inserted into the plug hole.
