Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and more specifically, to a novel sputum suction tube. Background Art

[0002] The suction tube is connected to the medical equipment, and then inserted into the patient's throat to suck out the phlegm in the throat, thereby achieving the treatment effect. After the use of the suction tube is finished, saline flushing is required, but the saline output tube is directly in contact with the suction tube for flushing. At this time, the phlegm on the inner wall of the suction tube will cause the saline output tube to be contaminated, which will not be conducive to subsequent use. Utility Model Content

[0003] In order to overcome the deficiencies of the prior art, the utility model provides a novel sputum suction tube, which has the advantage of preventing saline from being contaminated.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a new type of sputum suction tube, comprising a sputum suction tube, the top of which is fixedly connected to a flushing branch tube, the top of which is fixedly connected to a movable cannula, the inner cavity of the movable cannula is movably sleeved with a blocking rod, and the top of the blocking rod is fixedly connected to a pull ring.

[0005] As a preferred technical solution of the utility model, a scale bar is provided on the surface of the sputum suction tube, and a sputum suction nozzle is fixedly connected to the bottom end of the sputum suction tube.

[0006] As a preferred technical solution of the utility model, the sputum suction tube is movably sleeved with a bite ring, and the bite ring is a hollow body.

[0007] As a preferred technical solution of the utility model, a soft cushion is fixedly installed on the surface of the bite ring, and the bite ring is hourglass-shaped.

[0008] As a preferred technical solution of the utility model, the flushing branch tube is arc-shaped, and the flushing branch tube is connected with the inner cavity of the sputum suction tube.

[0009] As a preferred technical solution of the utility model, the sputum suction nozzle is conical, and the scale bar is in contact with the inner wall of the bite ring.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0011] 1. The utility model does not generate suction during use because the flushing branch tube does not generate suction during use. Even if a small amount of sputum enters, it will only affect a small area at the connection between the flushing branch tube and the sputum suction tube, and will not affect the position of the active cannula. After the sputum suction is completed, the blocking rod is pulled out of the inner cavity of the active cannula by pulling the pull ring by hand, and then normal saline is flushed into the inner cavity of the flushing branch tube. The normal saline flows along the flushing branch tube to the inner cavity of the sputum suction tube, thereby flushing the inner cavity of the sputum suction tube, avoiding the direct contact between the sputum suction tube and the output tube of the normal saline, resulting in the sputum in the inner cavity of the sputum suction tube contaminating the normal saline, thereby improving practicality.

[0012] 2. The utility model provides a scale bar on the surface of the suction tube, so that the doctor can observe the depth of the suction tube inserted into the patient's mouth through the scale on the scale bar, and then use the suction nozzle at the bottom of the suction tube to suck out the phlegm in the throat through the suction nozzle.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figures 1 to 5As shown, the utility model provides a novel sputum suction tube, comprising a sputum suction tube 1, a flushing branch tube 2 is fixedly connected to the top of the sputum suction tube 1, a movable cannula 3 is fixedly connected to the top of the flushing branch tube 2, a blocking rod 4 is movably sleeved in the inner cavity of the movable cannula 3, and a pull ring 5 is fixedly connected to the top of the blocking rod 4;

[0021] After the suction is completed, the blocking rod 4 is pulled out of the inner cavity of the movable cannula 3 by pulling the pull ring 5 by hand, and then normal saline is flushed into the inner cavity of the flushing branch tube 2. The normal saline flows along the flushing branch tube 2 to the inner cavity of the suction tube 1, thereby flushing the inner cavity of the suction tube 1, avoiding the suction tube 1 from directly contacting the output tube of the normal saline, resulting in the sputum in the inner cavity of the suction tube 1 contaminating the normal saline, thereby improving practicality.

[0022] The surface of the sputum suction tube 1 is provided with a scale bar 7, and the bottom end of the sputum suction tube 1 is fixedly connected with a sputum suction nozzle 8;

[0023] A scale bar 7 is provided on the surface of the suction tube 1, so that the doctor can observe the depth of the suction tube 1 inserted into the patient's mouth through the scale on the scale bar 7, and then use the suction nozzle 8 at the bottom of the suction tube 1. Since the suction nozzle 8 is in a pointed shape, it can firstly generate suction to suck out the sputum better, and secondly, it can have a small enough volume to better enter the throat, so that the sputum in the throat can be sucked out through the suction nozzle 8.

[0024] The suction tube 1 is movably sleeved with a bite ring 6, which is a hollow body;

[0025] By setting the bite ring 6, the patient can bite the bite ring 6, and the bite ring 6 supports the teeth of the patient's mouth, so that the bite ring 6 is a hard object, which can prevent the patient from biting the suction tube 1 closed, resulting in the situation that the sputum cannot be sucked out.

[0026] Among them, a soft cushion is fixedly installed on the surface of the bite ring 6, and the bite ring 6 is hourglass-shaped;

[0027] The soft pad on the surface of the bite ring 6 allows the patient to bite the bite ring 6 more comfortably, thereby avoiding the bite ring 6 being too hard and causing discomfort in the patient's oral cavity.

[0028] The flushing branch tube 2 is arc-shaped, and the flushing branch tube 2 is connected with the inner cavity of the sputum suction tube 1;

[0029] By making the flushing branch tube 2 into an arc shape, the opening of the flushing branch tube 2 is upward, so that the sputum can flow along the sputum suction tube 1, and then the flushing branch tube 2 is connected with the inner cavity of the sputum suction tube 1, so that the physiological saline in the inner cavity of the flushing branch tube 2 can be flushed into the inner cavity of the sputum suction tube 1, thereby flushing and cleaning the inner cavity of the sputum suction tube 1.

[0030] The suction nozzle 8 is conical, and the scale bar 7 fits the inner wall of the bite ring 6;

[0031] The sputum suction nozzle 8 is conical, so that the sputum suction nozzle 8 can suck out sputum through a smaller suction opening, and then the scale bar 7 fits with the inner wall of the bite ring 6, so that the bite ring 6 can mark the values ​​on the scale bar 7 more intuitively.

[0032] The working principle and use process of the utility model are as follows: the end of the sputum suction tube 1 away from the sputum suction nozzle 8 is connected to the sputum suction device for generating suction force, and then the sputum suction nozzle 8 is moved into the patient's oral cavity, and the position of the bite ring 6 is adjusted so that the patient can bite the bite ring 6, and the insertion depth of the sputum suction tube 1 is observed through the scale bar 7;

[0033] After the suction is completed, the pull ring 5 is pulled out by hand to pull the blocking rod 4 out of the inner cavity of the movable cannula 3, and then the saline output tube is brought into contact with the movable cannula 3, so that the saline can be flushed into the inner cavity of the flushing branch tube 2. At this time, since the flushing branch tube 2 will not generate suction during use, a small amount of sputum that enters in time will only affect a small amount of the connection between the flushing branch tube 2 and the sputum suction tube 1, and will not affect the position of the movable cannula 3. Then the saline is flushed into the inner cavity of the sputum suction tube 1 to flush the inner cavity of the sputum suction tube 1.
