It has characteristics such as flexibility, strength and corrosion resistance, and disposable or reusable types can be selected according to different needs. The Chinese utility model patent with the application number 202321781015.7 discloses a double-layer sputum suction tube, which includes an inner tube, an outer tube, a connecting tube and a switch assembly. The outer tube is sleeved outside the inner tube, the connecting tube is communicated with one end of the outer tube, a first through hole is opened on the outer side wall of the connecting tube, and the switch assembly is installed in the first through hole. A sieve hole area is provided at one end of the outer tube far from the connecting tube, and a plurality of second through holes are opened at one end of the inner tube far from the connecting tube.
[0003] For the above double-layer sputum suction tube, the double-layer sputum suction tube is connected to a negative pressure suction device through the connecting tube. Medical staff place the inner tube and the outer tube into the patient's tracheal catheter or oral cavity, close the switch assembly to close the first through hole, and the second through hole generates negative pressure to suck sputum and other liquids. However, it is found that there are defects in the use process: when the front end is inserted into the oral cavity, it is easy to cause trauma to the inner wall of the patient's airway, and when sucking, the front end directly touches the inner wall of the airway, and it is also easy to cause suction injury. Summary of the Utility Model
[0004] Aiming at the deficiencies of the prior art, the utility model provides a novel double-layer sputum suction tube, which can solve the problems that the front end of the conventional sputum suction tube is easy to cause trauma to the inner wall of the patient's airway when inserted, and the front end directly touches the inner wall of the airway during suction, and it is easy to cause suction injury.
[0005] To achieve the above purpose, the utility model provides the following technical solution: A novel double-layer sputum suction tube, including a first tube body on the outside, and a first arc-shaped bending part bent inward is fixedly arranged on the front end face of the first tube body;

[0028] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the utility model.
[0029] Embodiment 1, as Figures 1 to 3As shown in the figure, a new type of double-layer sputum suction tube includes a first tube body 1 on the outside. The front end face of the first tube body 1 is fixedly provided with a first arc-shaped bending part 12 that bends inward. A second tube body 2 is inserted into the first tube body 1. The front end face of the second tube body 2 is fixedly provided with a second arc-shaped bending part 22 that bends inward. A silica gel cover 11 is fixedly bonded to the lower port of the first tube body 1. A circular through hole 111 that is in frictional extrusion fit with the second tube body 2 is provided at the central position of the silica gel cover 11. A collar 23 is sleeved on the rear side of the front end part of the second tube body 2 in a damped manner. A smooth sphere 24 is fixedly provided on one side of the collar 23. A connector 21 is provided at the rear end part of the second tube body 2. The rotation of the second tube body 2 can drive the rotation of the sphere 24. The function of the damping is to slidably adjust the front and rear positions of the collar 23, thereby facilitating the adjustment of the length of the front end part of the second tube body 2 extending out of the first tube body 1.
[0030] The second arc-shaped bending part 22 at the front end part of the second tube body 2 is inclined to one side and abuts against the inner side of the first arc-shaped bending part 12.
[0031] The inner surface of the first tube body 1 has a smooth structure that cooperates with the sphere 24 to facilitate the rotation of the second tube body 2.
[0032] Arc-shaped handles 13 are also fixedly provided on both sides of the rear end part of the first tube body 1, which is convenient for the staff to grip and also helps to limit the position of the first tube body 1.
[0033] The length of the second tube body 2 is greater than the length of the first tube body 1.
[0034] During use, the first arc-shaped bending part 12 makes the front end part of the first tube body 1 relatively smooth, which can effectively protect the inner wall of the airway during insertion. The rear end part of the second tube body 2 is connected to a negative pressure device through the connector 21, which can play a role in sucking sputum at the front end part. The second arc-shaped bending part 22 at the front end part also plays a protective role. And the second arc-shaped bending part 22 abuts against the first arc-shaped bending part 12, which can prevent the second tube body 2 from extending out of the first tube body 1, thereby effectively avoiding the problem of damage to the inner wall of the airway caused by suction. The front opening of the second tube body 2 is completely open, which is suitable for the situation where there is a lot of sputum. The sphere 24 can keep the front end part of the second tube body 2 tilted to one side to prevent it from slipping out from the front end. Rotate the second tube body 2 at the rear end part to adjust the suction position at the front end. The circular through hole 111 facilitates the rotation of the second tube body 2 and also plays a sealing role.
[0035] Embodiment 2, as Figure 4 、 Figure 5 As shown in the figure, an elastic mesh cover 3 is detachably provided at the front end part of the second tube body 2.
[0036] The elastic mesh cover 3 includes a cylindrical silica gel sleeve 31 with an elastic rear opening. The front end of the silica gel sleeve 31 is in a spherical structure, and a number of mesh holes 32 are embedded in the spherical structure. A silica gel ring 33 is fixedly provided on the rear end face of the silica gel sleeve 31. A circular limiting protrusion 25 that cooperates with the silica gel ring 33 is fixedly provided on the rear side of the front end of the second tube body 2 (when the silica gel sleeve 31 is sleeved, the silica gel ring 33 is sleeved under the limiting protrusion 25).
[0037] During use, for the case of less sputum, the second tube body 2 can be first pulled out a part from the front port of the first tube body 1, then the elastic mesh cover 3 is sleeved on the top (front end) of the second tube body 2, and then the whole pipeline is inserted into the airway. Then, the elastic mesh cover 3 exposed at the front end can aspirate a small amount of sputum through the mesh holes 32, and the detachable structure is convenient for cleaning and replacement.
