Detailed Description

The present invention will be described in further detail with reference to the following examples and drawings.

As shown in fig. 1, the tracheotomy sealing device comprises a sleeve 1 externally connected with a tracheal cannula, wherein the sleeve 1 is made of transparent materials, and the sleeve 1 is formed by one-time injection molding. The sleeve pipe 1 is used for sealing the mouth of pipe of the tracheotomy tube, preventing infection, and facilitating the patient to enter a general ward or transfer from a severe ward. The size of the area of the tube opening of the sleeve 1 is changed, so that when a patient just pulls out the breathing machine, a short adaptation period is provided for the patient, the tracheotomy tube is prevented from being blocked completely at once, and discomfort is brought to the patient.

The lower end of the sleeve 1 is provided with an air outlet end 2 communicated with the trachea cannula, and the upper end of the sleeve 1 is provided with an air inlet end 3 communicated with the outside air.

With reference to fig. 2-4, the end surface of the air inlet end 3 is connected to a nozzle inlet flow rate adjustable adjusting device 4, the adjusting device includes a flow adjusting ring 401 and a plurality of elastic pieces 402 extending outwards along the air inlet end, and the end of the elastic pieces 402 close to the circumferential surface and far away from the air inlet end 3 can be bent outwards. An axially-arranged adjusting groove 101 is formed in the outer wall of the sleeve 1, the cross section of the adjusting groove 101 is T-shaped, and a plurality of limiting grooves 102 are vertically formed in one side of the adjusting groove 101; the bottom of the flow adjusting ring 401 is provided with a connecting rod 403, the connecting rod 403 is provided with a limiting rod 404 extending into the adjusting groove 101, and the end of the limiting rod 404 is provided with a limiting head 405.

Through the cooperation of gag lever post and adjustment tank, the vertical upward movement that the flow control ring can be shown along figure 1, and flow control ring moves to the assigned position after, rotates the flow control ring and lets the gag lever post get into the spacing groove thereby accomplish the injecing of flow control ring position.

As shown in fig. 5, one end of the elastic piece 402 away from the air inlet end 3 is provided with a plurality of shielding pieces 406 extending toward the center of the nozzle, and the plurality of shielding pieces 406 enclose a circular shape covering the nozzle. In order to ensure the sealing performance of the circular shape enclosed by the shielding sheet 406, preferably, a magnet 5 is embedded in the shielding sheet 406 near the center of the nozzle. When the shielding sheet 406 is enclosed into a circle, the adjacent magnets 5 are attracted to each other, so that the sealing effect is further ensured. In this embodiment, the elastic pieces 402 and the shielding pieces 406 are integrally formed, and the number of the elastic pieces 402 and the shielding pieces 406 is 4.

The flow adjusting ring moves upwards as shown in figure 1, so that the elastic pieces are controlled to gather, the shielding pieces are controlled to approach, and the ventilation quantity of the air inlet end is gradually reduced.

When the patient is in a better state and needs to be separated from a breathing machine to train mouth and nose breathing for the patient, according to the patient condition, when the patient is in a serious state, the flow adjusting ring 401 moves to the lowest end of the elastic sheet 402, at the moment, the gap between the adjacent elastic sheets 402 is kept to be the largest, namely, the gap between the adjacent elastic sheets 402 is in an inverted triangle shape, the shielding sheets 406 are farthest away from the center of the pipe orifice, namely, the shielding sheets 406 are all outwards radiated along the center of the pipe orifice in a synchronous and symmetrical mode and are in a divergent mode. At this time, the amount of intake air from the nozzle of the intake end 3 is kept to the maximum.

When the patient is required to train mouth-nose breathing when the condition of the patient is improved, the flow adjusting ring 401 is moved upwards to reduce the gap between the elastic pieces 402, meanwhile, the shielding piece 406 gradually approaches to the center of the tube opening, air can enter the body from the gap to provide the required oxygen amount, and the oxygen sucked from the nose is prevented from leaking from the opening at the lower end to a certain extent, and can be gradually reduced until the gap is closed according to the recovery condition of the patient.

In another embodiment of the present application, a more preferred tracheotomy sealing device structure is provided, as shown in fig. 1. Specifically, the side surface of the sleeve 1 is provided with an oxygen delivery port 7 matched with the breathing machine connector, and the oxygen delivery port 7 is communicated with the inner cavity of the sleeve 1. If the patient's condition suddenly changes and the patient is allowed to cooperate with the breathing machine to assist breathing, the flow adjustment ring 401 is located at the highest position outside the elastic pieces 402, and at the moment, the gap between the adjacent elastic pieces 402 is kept to be minimum, namely, the adjacent elastic pieces 402 are tightly attached. At the same time, the resultant circular shape enclosed by the shielding plate 406 completely covers the pipe orifice, and at this time, the air inlet end 3 stops air inlet. And the joint of the breathing machine is connected into the tube orifice of the tracheotomy tube through the oxygen delivery port 7, so as to provide auxiliary breathing for the patient.

The side surface of the sleeve 1 is also provided with an introducing port 8 matched with the sputum suction tube, and the introducing port 8 is communicated with the inner cavity of the sleeve 1. When the patient has sputum, the sputum suction tube is connected into the tube opening of the tracheotomy tube through the introducing port 8 to perform sputum clearing treatment on the patient.

As shown in fig. 6, in order to prevent contamination of the oxygen inlet 7 and the introduction port 8 when not in use, it is further preferable that both the oxygen inlet 7 and the introduction port 8 are fitted with a cap 9. In this embodiment, the entire plugging cap 9 is white and is formed by one-time injection molding.

The plugging cap 9 comprises a plug 901 and a plugging handle 902, the plugging handle 902 is arranged at the bottom of the plug 901, and the plugging handle 902 is in sealing fit with the inner walls of the oxygen delivery port 7 and the introducing port 8.

In yet another embodiment of the present application, a more preferred tracheotomy sealing device structure is provided, as shown in fig. 1. Specifically, an air filter bag 6 is arranged in the inner cavity of the sleeve 1 and close to the air inlet end 3. The air filter material is arranged in the air filter bag 6, so that air entering the patient body is effectively filtered, clean air can be inhaled by the patient in the autonomous respiration process of the patient in the recovery period, and infection caused by air pollution is avoided. In this embodiment, the air filter bag 6 is an activated carbon bag.

Further preferably, an air humidification block 10 is disposed on the side of the air filter pack adjacent to the air outlet end. Specifically, the air humidification block 10 may be a water-storing medical sponge, and may perform a regular water-replenishing operation on the medical sponge to ensure the humidification of the air inhaled by the patient and to prolong the service life of the cannula 1.

The present invention is not limited to the above-mentioned preferred embodiments, and any other products in various forms can be obtained by the teaching of the present invention, but any changes in the shape or structure thereof, which have the same or similar technical solutions as the present invention, fall within the protection scope of the present invention.
