Description

Technical Field

[0001] The present invention relates to the technical field of medical instruments, in particular to a sputum suction device. Background Art

[0002] Some patients experience phlegm accumulation in the throat and are unable to cough it up. Artificial suctioning is the only way to avoid dyspnea or shortness of breath and prevent aspiration pneumonia. Elderly individuals with weaker constitutions or critically ill patients often require suctioning. Suctioning involves suctioning secretions from the airways through a suction tube, either oral or nasal, or directly through the incision after a tracheotomy to maintain airway patency and prevent complications such as aspiration pneumonia, atelectasis, and asphyxia. It is suitable for patients who are comatose, have excessive sputum and are at risk of asphyxiation, or require intratracheal medication, contrast agent administration, or sputum dilution. However, sputum is often viscous, making it prone to blockage when suctioned through a suction tube, resulting in incomplete suction. This also creates the risk of sputum reflux, hindering recovery. Summary of the Invention

[0003] In view of the deficiencies in the prior art, the present invention provides a sputum suction device with a simple and reasonable structure, which avoids blockage in the sputum suction tube and is simple in structure and easy to implement.

[0005] The beneficial effect of such a setting is: with such a setting, the magnetic pole of the iron core is changed by the action of the iron core, the circuit board and the winding, and by the change of the direction of the current. Furthermore, a magnetic ring is provided on the inner wall of the sliding sleeve, thereby driving the sliding sleeve in the dispersion chamber to slide back and forth. At the same time, a dispersion groove is provided on the side wall of the sliding sleeve. During the reciprocating motion, the incoming sputum is dispersed to avoid the concentration of the sputum and blockage, thereby avoiding the phenomenon of sputum reflux. The circuit board here can realize magnetization by connecting to the power supply, driving the sliding sleeve to move, and further adopting an electromagnetic drive method. There is no other connection port, thereby avoiding the leakage of sputum, which is more hygienic and safe. At the same time, the structure is simple, which is conducive to implementation, and effectively improves the use effect of the sputum suction device.

[0006] As a further configuration of the present invention, the sliding sleeve is tapered at one end toward the connection port, the tapered tip is toward the connection port, separation grooves are spaced apart on the outer peripheral wall of the tapered tip of the sliding sleeve, and the separation grooves are connected to the dispersion grooves.

[0007] The beneficial effect of this setting is: setting a conical tip can effectively break up the sputum coming out of the connection port, and cooperate with the separation groove to further separate the sputum. At the same time, the separated sputum will further enter the dispersion groove for separation, thereby avoiding the concentration of sputum.

[0008] As a further configuration of the present invention, the iron core is configured to be E-shaped, and the iron core includes a middle column and two side columns arranged on both sides of the middle column, and the winding is wrapped around the middle column.

[0009] The beneficial effect of such a setting is that it is set in an E shape, a magnetic pole is formed at the position of the middle column, and another magnetic pole is formed on the two side columns. The current is alternately transformed, so that the magnetic poles of the middle column and the side column are alternately transformed, thereby driving the sliding sleeve to slide along the columnar protrusion. The setting in the E shape makes the sliding sleeve more stable during the sliding process, reduces the movement amplitude, and improves the stability of the overall structure.

[0010] As a further configuration of the present invention, the suction ports are provided in plurality and are arranged within the range of the projection of the sliding sleeve on the end surface of the base body.

[0011] The beneficial effect of this setting is: this setting ensures that the sputum to be sucked needs to pass through the position of the sliding sleeve, so that the sliding sleeve can better separate and cut the sputum, ensuring that the aggregated sputum can be dispersed to avoid blockage. At the same time, multiple suction ports are set to reduce the possibility of blockage of the suction ports, thereby effectively separating. This structure is simple and easy to implement.

A number of dispersion grooves 41 for dispersing sputum are arranged at intervals on the outer peripheral wall of the sliding sleeve 4, and a suction port 22 is provided on the base 2 at the corresponding position of the accommodating groove, and the sputum suction tube 3 is connected to the base 2 through the suction port 22. The beneficial effect of such a setting is: with such a setting, the magnetic pole of the iron core 5 is changed by changing the direction of the current through the action of the iron core 5, the circuit board 52 and the winding 51. Furthermore, a magnetic ring 43 is provided on the inner wall of the sliding sleeve 4, thereby driving the sliding sleeve 4 in the dispersion chamber to slide back and forth. At the same time, a dispersion groove 41 is provided on the side wall of the sliding sleeve 4. During the reciprocating motion, the incoming sputum is dispersed to avoid the concentration of the sputum and blockage, thereby avoiding the phenomenon of sputum reflux. The circuit board 52 here can realize magnetization by connecting to the power supply, driving the sliding sleeve 4 to move, and further adopting an electromagnetic drive method. There is no other connection port, which avoids the leakage of sputum, is more hygienic and safe, and has a simple structure, which is conducive to implementation, and effectively improves the use effect of the sputum suction device.

[0016] As a further feature of the present invention, the sliding sleeve 4 is tapered at one end facing the connection port, with the tapered tip facing the connection port. Separation grooves 42 are spaced apart on the outer peripheral wall of the tapered tip of the sliding sleeve 4. The separation grooves 42 are connected to the dispersion groove 41.

At the same time, the provision of multiple suction ports 22 reduces the possibility of blockage of the suction ports 22, thereby effectively performing separation. This structure is simple and easy to implement.
