[0020] like Figures 2 to 4 As shown, the nursing suction tube described in the present invention includes a suction tube body 1 and a negative pressure regulating component 2, the negative pressure regulating component 2 includes a negative pressure regulating tube 21 and a sliding sleeve 22, one end of the negative pressure regulating tube 21 is fixedly provided with a negative pressure joint 217, the other end of the negative pressure regulating tube 21 is connected to one end of the suction tube body 1, the negative pressure regulating tube 21 is provided with a cavity 211 running through both ends thereof, the outer circumferential surface of the negative pressure regulating tube 21 is provided with a negative pressure regulating port 212, the sliding sleeve 22 is adapted to the negative pressure regulating tube 21, the sliding sleeve 22 is sleeved on the outside of the negative pressure regulating tube 21 and can slide back and forth between a first position sealing the negative pressure regulating port 212 and a second position not sealing the negative pressure regulating port 212, the outside of the negative pressure regulating tube 21 is provided with a front limiting portion 213 and a rear limiting portion 214 for limiting the forward and backward sliding of the sliding sleeve 22.

[0021] Through the setting of the sliding sleeve 22, during the suction operation, the operator can slide the sliding sleeve 22 so that the sliding sleeve 22 covers or does not cover the negative pressure regulating port 212 to open or block the negative pressure regulating port 212, so that the suction end of the suction tube body 1 has no negative pressure effect or has a negative pressure effect. In this way, sputum will not be contaminated by the operator's hands, which is more conducive to hygiene during the suction operation; through the setting of the front limiting part 213 and the rear limiting part 214, the sliding sleeve 22 can be effectively prevented from being separated from the negative pressure regulating tube 21; in addition, the negative pressure connector 217 is used to be plugged into the negative pressure tube of the suction device, and the negative pressure connector 217 is tower-shaped.

[0022] In addition, the negative pressure regulating tube 21 also includes a compression spring 23, which is sleeved on the outside of the negative pressure regulating tube 21 and located between the rear limit portion 214 and the sliding sleeve 22. The compression spring 23 is used to always apply an elastic force toward the front limit portion 213 to the sliding sleeve 22 and enable the sliding sleeve 22 to keep sealing the negative pressure regulating port 212.

[0023] In addition, an annular shielding plate 221 for shielding the compression spring 23 is fixedly provided at one end of the sliding sleeve 22 to prevent the compression spring 23 from being directly exposed to the outside.

[0024] Preferably, the rear limiting portion 214 is an annular protrusion, which is fixed on the outer circumference of the negative pressure regulating tube 21. The front limiting portion 213 is an elastic retaining ring, and an annular groove is provided on the outer circumference of the negative pressure regulating tube 21. The elastic retaining ring is clamped in the annular groove, thereby facilitating the assembly of the sliding sleeve 22 and the compression spring 23 on the negative pressure regulating tube 21.

[0025] In addition, annular sealing grooves are provided on the outer peripheral surface of the negative pressure regulating tube 21 on both the front and rear sides of the negative pressure regulating port 212, and an O-ring 24 is provided in the annular sealing groove, which is conducive to improving the sealing performance of the sliding sleeve 22 when sealing the negative pressure regulating port 212.

[0026] Preferably, the negative pressure regulating port 212 is in the shape of a long hole.

[0027] In addition, a plurality of anti-skid grooves 222 are evenly distributed on the outer circumference of the sliding sleeve 22, thereby making the outer circumference of the sliding sleeve 22 have a better anti-skid effect, so as to push the sliding sleeve 22 to slide more smoothly.

[0028] The sputum suction tube also includes a sputum suction connector 3, which is tower-shaped. One end of the sputum suction tube body 1 is fixedly provided with the sputum suction connector 3, and one end of the negative pressure regulating tube 21 extends outward and forms a plug-in portion 215. The sputum suction connector 3 can be detachably plugged into the plug-in portion 215. In this way, a detachable connection between the sputum suction tube body 1 and the negative pressure regulating component 2 can be achieved. After suctioning once, it is only necessary to remove the sputum suction tube body 1 together with the sputum suction connector 3 and replace them, and the negative pressure regulating component 2 can also be reused. In addition, an elastic pad 216 is fixedly provided on the inner surface of the plug-in portion 215, and the elastic pad 216 can be made of rubber or silicone material. Therefore, when the sputum suction connector 3 is inserted into the plug-in portion 215, the elastic pad 216 can be squeezed, thereby further improving the stability of the plug-in between the two.

[0029] When performing sputum suction, take the insertion of the suction tube into the patient's mouth as an example:

[0030] After the phlegm suction is completed, normal saline can be sucked again, and the phlegm suction tube body 1 can be rinsed and discarded.

[0031] The above are only some specific implementation methods of the present invention, but the design concept of the present invention is not limited to this. Any non-substantial changes to the present invention using this concept shall be deemed as an infringement of the protection scope of the present invention.
