After rotating the external container clockwise to the specified position, the bulges on both sides of the blocking structure are respectively inserted into the inlet and the outlet, and the blocking structure is locked and connected with the container cover.

[0088] After rotating the container counterclockwise, the through hole I is connected to the outlet, the container cover cooperates with and is locked to the groove structure, the through hole II is connected to the inlet, negative pressure is applied to the through hole I, and negative pressure is generated in the container and the through hole II, so that the specimen collected in the through hole II is input into the container body; after rotating the container clockwise, the container cover is disengaged from the groove structure, and at the same time, the sealing structure is cooperated with and locked to the boss 221, and after the inlet and the outlet are sealed, the container moves outward to disengage from the transfer device, thereby completing the closed collection of the specimen.

[0098] The operation process of this embodiment is as follows:

[0099] (1) Sputum collection process:

[0100] Connect the transfer sealing device and the system to the negative pressure suction device, turn on the negative pressure, and send the suction tube body along the endotracheal tube to the patient's bronchial position; by pushing the sliding cover 12, close the pressure relief hole 111, and start sputum collection. At this time, the entire system has only one channel at the far end of the tube body connected to the outside world, and sputum is sucked through this channel. The sputum in the patient's lungs or airways is sucked into the sputum collection bottle by the negative pressure. When the sputum collection is completed, in order to prevent cross contamination, the sputum collection bottle and the suction device are separated by displacement or twisting between the components. That is, by twisting the sputum collection bottle 2 by 90°, the sputum collection bottle 2 and the adapter 1 are separated. During this process, the blocking member 3 automatically cooperates with the boss 221 of the bottle cap 22, and the blocking member 3 covers the outer side of the boss 221 to close the air inlet 222 and the exhaust 223 on both sides of the boss 221. The specimen in the sputum collection bottle 2 is isolated from the environment, and the specimen in the sputum collection bottle 2 is sealed. The sputum collection bottle 2 with the collected specimen is transferred to the detection room. When the specimen is to be tested, the bottle body 21 and the bottle cap 22 can be separated from each other by relative rotation to take out the specimen.

[0101] (2) Alveolar lavage process:

[0102] Connect the syringe tip filled with saline to the positive pressure connector 112 at the rear of the connector body 11, and turn on the switch 113 so that the proximal through hole of the adapter 1 is closed, and the positive pressure connector 112 is connected to the inner cavity of the tube body II. Inject the saline in the syringe into the positive pressure connector 112, and the saline is injected into the patient's lungs along the inner cavity of the tube body II. Turn on the switch 113 again to open the inner cavity of the proximal through hole of the adapter 1, and the positive pressure connector 112 is isolated from the inner cavity of the tube body II. Insert the pagoda-shaped head at the distal end of the adapter 1 into the negative pressure aspirator, and start the normal aspiration process to suck out all the saline injected into the patient's lungs, and at the same time drive the aspiration of viscous sputum in the lungs.

[0103] Example 3

[0104] like Figure 3 As shown, the difference from the embodiment 2 is that the other end of the tube body Ⅰ5 in this embodiment is connected to a semi-closed joint. The semi-closed joint includes a joint Ⅰ61 and a protective sleeve buckle 62. The proximal outer wall of the joint Ⅰ61 is provided with a buckle 616. One side of the protective sleeve buckle 62 is matched with the buckle 616, and the other side is connected to the tube body protective sleeve 4 provided on the outer surface of the tube body Ⅰ5.

[0105] like Figure 7-14 As shown. The connector I 61 includes a distal structure and a connector body 611, and the distal structure and the connector body 611 are sealed. In addition, the connection between the connector body 11 and the tube body protective sleeve 4 disposed outside the tube body I 5 can be hot melt connection, adhesive connection, or welding connection in addition to using the protective sleeve buckle 2.

[0106] The distal structure is a double-layer structure, which consists of a distal inner conical tube 614 placed in the inner layer and a distal outer shell 615 placed in the outer layer. There is a gap between the outer wall of the distal inner conical tube 614 and the inner wall of the distal outer shell 615; the inner wall of the distal outer shell 615 can be connected to the endotracheal tube connector 63 or the multi-purpose connector of the ventilator, and the outer wall of the distal outer shell 615 is the hand-holding part; the outer shape of the distal inner conical tube 614 is a truncated cone structure, and its outer wall is connected to multiple models of endotracheal tube bodies 64. The interior of the distal inner conical tube 614 is provided with an inner cavity, which is the channel of the tube body Ⅰ5.

[0107] A through hole communicating with the inner cavity is provided in the middle of the joint body 611 for the tube body I5 to pass through. The tube body I5 passes through the through hole and the inner cavity in sequence and reaches the outside of the inner cavity. Among them, the through hole is a variable diameter structure or a multi-inner diameter structure. The "variable diameter structure" refers to the inner diameter of the proximal end of the through hole and the outer diameter of the tube body Ⅰ5 being close, so that there is no gap between the through hole and the tube body Ⅰ5, ensuring that the negative pressure will not be transmitted to the tube body protective sleeve 5 (if there is negative pressure in the tube body protective sleeve 4, it will be sucked in); the "multi-inner diameter structure" and the variable diameter structure have the same purpose to be achieved. The variable diameter structure is a gradual change, and the multi-inner diameter structure has a step-shaped cross section; the proximal end of the joint body 611 is provided with an inner diameter contraction platform 617 (inner diameter reduction design), and the interior of the inner diameter contraction platform 617 is provided with a through inner hole connected to the through hole, and the inner hole is used for the tube body Ⅰ5 to pass through; the inner wall of the inner hole is fitted and connected with the outer wall of the tube body Ⅰ5, the inner diameter of the inner hole is close to the outer diameter of the tube body Ⅰ5, and the inner diameter of the inner cavity is larger than the outer diameter of the tube body Ⅰ5, ensuring that the negative pressure at the distal end of the tube body Ⅰ5 is not transmitted to the tube body protective sleeve 4.

[0108] The connector body 611 is provided with at least two air exchange holes 613 connected to the outside world in the circumferential direction. The air exchange holes 613 are inclined, and their openings are facing the patient's mouth, that is, the axis of the air exchange hole 613 forms a certain angle with the central axis of the connector body 611, and the angle is less than or equal to 90 degrees, which can prevent droplets; the connector body 611 is provided with a concealed air exchange channel 618 inside, and the two sides of the air exchange channel 618 are respectively connected to the air exchange holes 613 and the through holes. The air exchange channel 618 is used to connect the inner cavity of the connector 6 and the outside world, which can prevent the patient from suffocating during sputum suction. When sputum is suctioned, the tube body Ⅰ5 is under negative pressure, and the air enters the tube body Ⅰ5 through the air exchange holes 613, the air exchange channel 618, the through holes, the inner cavity, the endotracheal tube body 64, and the patient's lungs in turn. The air circulation also drives the suction of sputum in the patient's lungs. The air circulation in the air exchange channel 618 during sputum suction is shown in FIG. Fig.15 .

[0109] The end of the above-mentioned distal outer shell 615 is connected with a protective cover 612, which is used to close the joint 6 after the operation is completed; the protective cover 612 is a concave structure with a groove inside to prevent the inner wall from being contaminated during operation; the internal size of the groove is larger than the outer wall size of the distal outer shell 615 to ensure that the operator is not contaminated when the protective cover 612 is opened and closed; the protective cover 612 and the distal outer shell 615 are integrally formed, or connected by hot melt, or connected by adhesive, or connected by welding, or connected by a lock.

[0110] The integrated, fully enclosed sputum collector is used in conjunction with the semi-enclosed connector to achieve full coordination between the product and the endotracheal tube connector 63 and the endotracheal tube body 64. At the same time, the semi-enclosed connector itself contains a protective cover 612 to prevent sputum from being exposed after the sputum suction process is completed.

The disc is provided with two axial through holes, and the sputum collection bottle cap is also provided with two holes. The holes on the sputum collection bottle cap and the through holes on the disc can be connected and misaligned by rotating the disc. When the two pairs of holes are misaligned, the disc will seal the sputum collection bottle cap. Figure 16-21 shown.

[0113] Example 5

[0114] Different from the fourth embodiment, the blocking structure in the present embodiment is a cylindrical structure, a cylindrical groove is arranged inside, the preset groove 114 arranged inside the groove structure is a cylindrical groove with a certain depth, and the blocking structure is embedded in the preset groove 114. The boss 221 is a cylindrical structure, and its outer surface is provided with an external thread. The boss 221 is inserted into the cylindrical groove of the blocking structure, and the inner surface of the cylindrical groove is provided with an internal thread, which is matched and connected with the external thread of the boss 221 to achieve locking between the blocking structure and the boss 221. Two holes are provided on the side wall of the blocking structure. When the external container is rotated to a specified position, the two holes on the blocking structure are respectively connected with the air inlet 222 and the air outlet 223 on the boss 221 to perform sputum suction. After the sputum suction is completed, the external container is rotated, the blocking structure is locked and connected with the boss 221, and after the inlet and the outlet are sealed, the external container is pulled out at the same time, and the blocking structure moves outward with the external container to detach from the transfer device, thereby completing the closed collection of the specimen.
