[0022] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] Reference Figure 1 , a double-chamber sputum suction device, comprising a sputum suction tube 1 and a flushing tube 2, wherein:

[0024] The sputum suction tube 1 is connected to a negative pressure suction device on the outside, and is used to be inserted into the patient's trachea to complete the sputum suction operation; the sputum suction tube 1 is vertically arranged as a whole, with a vertical length of 450 mm and a diameter of 4.6 mm;

[0025] Suction holes 101 are provided at the top and both sides of the top of the sputum suction tube 1. Figure 1 As shown in FIG, the number of suction holes 101 is shown to be only three, one at the top and one on each side of the top;

[0026] In actual use, the number of suction holes 101 can be several (not shown in the figure), and multiple suction holes 101 can be opened on both sides of the top of the suction tube 1; when the suction tube 1 is used to suction sputum in the patient's trachea, the suction holes 101 opened at the top and both sides of the top of the suction tube 1 have a larger suction direction and range, and can efficiently suck out the accumulated sputum in the patient's trachea, with high suction efficiency, shortening the required treatment time;

[0027] The flushing pipe 2 can be connected with the expectorant storage device and the flushing liquid storage device. The flushing pipe 2 is shorter than the sputum suction tube 1, with a length of 417 mm. The flushing pipe 2 and the sputum suction tube 1 are integrated to form an outer tube body 100. The top of the flushing pipe 2 and the bottom of the sputum suction hole 101 are provided with a flushing port 201. When the patient's trachea is suctioned, the flushing pipe 2 and the sputum suction tube 1 are integrated together and can be inserted into the trachea together. When the flushing pipe 2 outputs the expectorant / flushing liquid, the sputum suction tube 1 also performs the sputum suction operation. The expectorant and sputum suction treatment operations are performed simultaneously, which simplifies the nursing operation of the nursing staff, improves the sputum suction efficiency, and thus shortens the overall treatment time and reduces the discomfort caused by the treatment.

[0028] In addition, when suctioning and flushing are performed simultaneously, an independent flushing pipe 2 on one side of the outer tube body 100 is injected with expectorant, which can effectively dissolve the accumulated sputum and effectively avoid the patient's sputum splashing, causing pollution to nursing staff and the surrounding environment; and suctioning and flushing at the same time can reduce the incidence of patient aspiration.

[0029] Further, such as Figure 1 As shown, the sputum suction holes 101 at both sides of the top of the sputum suction tube 1 are arranged in an up-and-down staggered manner (there is one sputum suction hole 101 at each side of the top of the sputum suction tube 1);

[0030] The sputum suction hole 101 is located on the same side as the flushing port 201, the sputum suction hole 101 is located 7 mm downward from the top of the sputum suction tube 1, and the sputum suction hole 101 is spaced 18 mm from the flushing port 201;

[0031] The sputum suction hole 101 is located on the opposite side of the flushing port 201 and is located 17 mm downward from the top of the sputum suction tube 1;

[0032] Specifically, through the above-mentioned design, the suction holes 101 at both sides of the top of the suction tube 1 are staggered up and down. The suction holes 101 staggered up and down are convenient for sucking out the accumulated sputum at different positions along the length direction of the trachea, thereby further improving the suction efficiency and shortening the treatment time.

[0033] Further, such as Figure 1 As shown, the outer tube body 100 is made of a transparent material, and dimension marking lines are provided on the outer tube body 100;

[0034] Specifically, the outer tube body 100 is provided with dimension marking lines to observe the scale position of the expectorant or flushing fluid outlet, and the inserted length of the sputum suction tube 1 is adjusted to accurately flush the sputum on the exposed endotracheal tube wall of the patient.

[0035] Further, such as Figure 1 As shown, a connecting valve body 3 is provided at the bottom of the outer tube body 100, and its vertical length is 15 mm. A negative pressure suction connector 4 is provided at the bottom of the connecting valve body 3, and its vertical length is 20 mm. The negative pressure suction connector 4 is connected to the inner cavity of the sputum suction tube 1 through the connecting valve body 3;

[0036] The negative pressure suction connector 4 is used to connect to an external negative pressure suction device, so that negative pressure suction can be generated in the inner cavity of the sputum suction tube 1, and then the sputum suction holes 101 at the top and both sides of the top of the sputum suction tube 1 can suction the sputum accumulated in the patient's trachea;

[0037] The connecting valve body 3 also includes a water pipe 5 located at the bottom of the connecting valve body 3, which is 1500 mm long. The water pipe 5 is connected to the inner cavity of the flushing pipe 2 through the connecting valve body 3; a water supply switch is provided on the water pipe 5, which is a clip 9, and the clip 9 is 15 mm long. An installation joint 6 is provided at one end of the water pipe 5 away from the connecting valve body 3, and its diameter is 8 mm;

[0038] Through the mutual cooperation of the flushing pipe 2, the water-passing pipe 5 and the installation joint 6, the installation joint 6 can be connected with the external expectorant storage device and the flushing liquid storage device, so that the expectorant / flushing liquid can flow along the water-passing pipe 5 to the flushing pipe 2, thereby realizing the supply of the expectorant / flushing liquid to the inside of the flushing pipe 2, and the clamp 9 can realize the opening or closing of the expectorant / flushing liquid supply.

[0039] Further, such as Figure 1 As shown, the connecting valve body 3 is provided with a suction tube negative pressure port 7, which is elliptical in shape and has a long diameter R of 10 mm. The suction tube negative pressure port 7 is connected to the inner cavity of the suction tube 1, and a cover body 701 is provided on the suction tube negative pressure port 7;

[0040] The connecting valve body 3 is provided with an expectorant injection port 8, which is circular in shape and has a diameter r of 7 mm, and is used to directly inject the expectorant into the flushing water pipe 2. The expectorant injection port 8 is connected to the inner cavity of the flushing water pipe 2, and a cover body 801 is provided on the expectorant injection port 8;

[0041] Specifically, during use, when suctioning phlegm first and then flushing the tube: first clamp the clamp 9 on the water pipe 5, then seal the cover body 1 701 and the cover body 2 801 to cover the negative pressure port 7 and the expectorant injection port 8 of the suction tube, so that the flushing pipe 2 stops running, and the suction treatment of the suction tube 1 can be achieved; when flushing the tube, open the clamp 9 to achieve flushing;

[0042] When suctioning phlegm and flushing the tube at the same time: first open the clamp 9 on the water pipe 5, and seal the cover body 1 701 and the cover body 2 801 to cover the suction tube negative pressure port 7 and the expectorant injection port 8 at the same time, the suction tube 1 and the flushing tube 2 can be operated at the same time, and suctioning phlegm and flushing the tube are completed simultaneously;

[0043] First eliminate phlegm and then suction it: first close the clamp 9 on the water pipe 5, inject the expectorant into the expectorant injection port 8, after a suitable time, seal the cover 1 701 and the cover 2 801 to cover the negative pressure port 7 and the expectorant injection port 8 of the suction tube, then open the clamp 9, flush with water to eliminate phlegm, and then suction the phlegm.
