The invention provides a sputum aspirator tube, which comprises a main tube 1 with an inner pipe 11 and an absorber ball 2 arranged at one end of the main tube 1, wherein the end of the main tube 1 far away from the absorber ball 2 is formed into a connecting end 12 to be connected with a negative pressure aspirator, as shown in fig. 1-3. The main body tube 1 and the absorption ball 2 are generally integrally manufactured from medical PVC material. Wherein the absorption ball 2 includes a convex portion radially protruding from an outer circumferential surface of the main body pipe 1, and an outer wall surface obliquely extending from the convex portion toward a central direction of the main body pipe 1 is formed on the absorption ball 2, and an absorption hole 21 communicating with an inner pipe 11 of the main body pipe 1 is provided on the outer wall surface. Here, the outer wall surface extending obliquely toward the center of the main body tube 1 means that the outer wall surface extends obliquely away from the center of the main body tube 1 while extending toward the center, and may be linearly or curvilinearly extending obliquely.
In the sputum suction tube provided by the invention, when the sputum suction tube is used, the connecting end 12 of the main body tube 1 far away from the absorption ball 2 is connected with the negative pressure suction device, one end of the sputum suction tube with the absorption ball 2 stretches into the air tube 3, as shown in fig. 4 and 5, one side of the absorption ball 2 with the absorption hole 21 is adjusted to correspond to one side of any air tube wall 31 with the sputum 4, as the absorption ball 2 protrudes out of the main body tube 1, a cavity is formed between the obliquely extending outer wall surface of the absorption ball 2 with the absorption hole 21 and the air tube wall 31, one end of the sputum 4 is positioned in the cavity, so that after the negative pressure suction device connected with the main body tube 1 is started, one end of the sputum 4 can be lifted under the action of the suction flow of the absorption hole 21 (as shown in fig. 6), then the gap 5 between the sputum 4 and the air tube wall 31 can enter the air 6, and the sputum 4 can gradually leave the air tube wall 31 and enter the absorption hole 21 (as shown in fig. 7).
Compared with the mode of pulling out the sputum perpendicular to the tracheal wall in the prior art, the sputum suction tube provided by the invention can adsorb the sputum without larger suction force due to the adoption of the mode of gradually separating the sputum from the tracheal wall after lifting one end, thereby avoiding the risk of damaging and bleeding the tracheal wall due to larger suction force and improving the sputum suction efficiency.
The following describes the technical scheme of the invention in detail according to a preferred embodiment of the invention with reference to the accompanying drawings.
In a preferred embodiment of the present invention, as shown in fig. 1 and 2, an outer wall surface inclined toward the center direction of the main body tube 1 is formed on the side of the absorption ball 2 facing the main body tube 1, and as shown in fig. 3, a first outer wall surface 23 inclined is formed in a substantially tapered shape (may be an arc-shaped surface), and the absorption hole 21 is located on the first outer wall surface 23.
One side of the absorbing ball 2, which is far away from the main body tube 1, is formed into a conical structure, so that the absorbing ball 2 can easily enter into a trachea with any sputum, and the problem that the sputum suction tube in the prior art is difficult to insert is solved.
In the solution provided in the present invention, the absorption holes 21 are not limited to be provided on the first outer wall surface 23 of the absorption ball 2 facing the main body tube 1, but may be provided on the outer wall surface of the absorption ball 2 facing away from the main body tube 1, for example, the second outer wall surface 24 shown in fig. 3.
It will be appreciated by those skilled in the art that the structure of the absorbent ball 2 is not limited to the one provided in the present embodiment, and other structures that protrude from the main body tube 1 and have rounded outer surfaces may be used. For example, the absorption ball 2 may be provided in a substantially spherical structure, and the absorption hole 21 may be provided on an arc-shaped outer wall surface of the absorption ball 2 on a side facing the main body tube 1 or on an arc-shaped outer wall surface on a side facing away from the main body tube 1.
Preferably, an angle between the axis of the absorption hole 21 and the axis of the end of the main body tube 1 near the absorption ball 2 is 20 ° to 80 °. This angular arrangement allows the absorption hole 21 to better lift the sputum from one end of the sputum, i.e. to facilitate a reduction in the suction force required to absorb the sputum.
In this embodiment, as shown in fig. 3, the angle between the axis of the absorption hole 21 and the axis of the end of the main body tube 1 near the absorption ball 2 is 60 °.
Preferably, the diameter of the absorption holes 21 is smaller than the diameter of the inner pipe 11 of the main body pipe 1, more preferably 1.5 to 5mm.
In the present embodiment, an internal cavity 22 is formed inside the absorption ball 2, and the internal cavity 22 communicates with the absorption hole 21 and the internal pipe 11 of the main body pipe 1, so that the sputum adsorbed by the absorption hole 21 first enters the internal cavity 22, and is then sucked away from the internal cavity 22 along the internal pipe 11 of the main body pipe 1.
Preferably, to allow the absorbent ball 2 to easily extend into the trachea, the tapered end 25 of the absorbent ball 2 may be formed to be solid as shown in fig. 3 to increase the stiffness of the end of the absorbent ball 2 so as to facilitate the absorbent ball 2 not collapsing by the gas or other material in the trachea when extending into the trachea.
In order to avoid dead angles for accumulating sputum in the inner cavity 22 of the absorption ball 2, the inner wall surface of the inner cavity 22 of the absorption ball 2 is smooth, which is beneficial to gas flow. That is, there is no dead angle or an angle which is unfavorable for the air flow in the inner cavity 22 of the absorption ball 2, so that the air from the inner pipe 11 of the main pipe 1 can more thoroughly suck the sputum inside the absorption ball 2.
In the present embodiment, as shown in fig. 1 and 2, the body tube 1 is further provided with an air hole 13, and the air hole 13 is preferably located in a position of the body tube 1 away from the absorbent ball 2. When the sputum aspirator is in a working state, the air hole 13 can be closed, and the negative pressure suction device can suck the air in the sputum aspirator; when the sputum aspirator is in a non-working state, the air hole 13 can be opened, and negative pressure can not be formed in the sputum aspirator due to the communication function of the air hole 13.
In this embodiment, the central axis of the air hole 13 and the central axis of the absorption hole 21 are preferably located in the same plane, as shown in fig. 2. When the sputum suction tube stretches into the trachea, the opening direction of the absorption hole 21 can be judged through the opening direction of the air hole 13, so that the relative position relation of the direction of the absorption hole 21 and the trachea wall is conveniently adjusted to be oriented to any trachea wall with sputum.
According to another aspect of the present invention, there is also provided a sputum aspirator comprising a negative pressure suction apparatus and a sputum aspirator tube as described above, the negative pressure suction apparatus being connected to an end of the main tube remote from the absorbent ball to suck gas in the main tube.
According to another aspect of the present invention, there is also provided a method for sucking sputum using a sputum suction tube as described above, the method comprising:
Extending one end of the sputum aspirator tube with the absorbing ball 2 into the trachea;
adjusting the absorption ball 2 by rotating and/or lifting the main body tube 1 so that one side of the absorption ball 2 having the absorption hole 21 is close to any tracheal wall having sputum, and the absorption hole 21 is positioned at one end of the sputum;
the gas in the main tube 1 is sucked, and the sputum gradually leaves the tracheal wall from one end and enters the absorption hole 21.
In order to facilitate the adjustment of the direction of the absorption ball 2, the main body pipe 1 is provided with an air hole 13, and the central axis of the air hole 13 and the central axis of the absorption hole 21 are positioned on the same plane;
The step of adjusting the absorbent ball specifically includes: the relative position relationship of the absorption hole direction in the sputum aspiration process and the tracheal wall is adjusted by rotating and/or lifting the main body tube 1 according to the direction of the air hole 13.
The following describes a specific process of sputum aspiration by adopting the technical scheme provided by the invention.
As shown in fig. 4, one end of the sputum suction tube with the absorbing ball 2 extends into the trachea 3, the sputum 4 is positioned on one side of the trachea 3 on the tracheal wall 31, and the sputum suction tube is adjusted so that the absorbing hole 21 on the absorbing ball 2 faces any of the tracheal walls 31 with the sputum 4, and the absorbing hole 21 is positioned at one end of the sputum 4.
As shown in fig. 5, the connecting end 12 of the sputum aspirator remote from the absorber ball 2 is connected with a negative pressure suction device through the air exhaust pipe 7, the negative pressure suction device is started to suck the air in the sputum aspirator, and the sputum 4 on the air pipe wall 31 is lifted up at one end of the sputum 4 close to the absorber hole 21 under the action of the air flow of the absorber hole 21 and moves towards the absorber hole 21. As shown in fig. 6, when one end of the sputum 4 is lifted, the gas 6 enters the gap 5 between the sputum 4 and the tracheal wall 31, and as the sputum 4 gradually leaves the tracheal wall 31, the gas 6 entering the gap 5 increases, and the sputum 4 gradually leaves the tracheal wall 31.
As shown in fig. 7, the sputum 4 leaves the tracheal wall 31 and gradually enters the internal cavity 22 from the absorption hole 21 of the absorption ball 2 under the action of the airflow, then enters the internal pipe 11 of the main body tube 1 from the internal cavity 22, and finally is guided out from the suction tube 7, thus completing sputum suction.
The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Within the scope of the technical idea of the invention, a number of simple variants of the technical solution of the invention are possible, including combinations of individual specific technical features in any suitable way. The various possible combinations of the invention are not described in detail in order to avoid unnecessary repetition. Such simple variations and combinations are likewise to be regarded as being within the scope of the present disclosure.
