At the same time, the terms such as "upper", "lower", "left", "right", "middle" and "one" quoted in this specification are only for the convenience of description, and are not used to limit the scope of the implementation of the utility model. The change or adjustment of the relative relationship should also be regarded as the scope of the implementation of the utility model without substantial change of the technical content.

[0031] like Figure 1-2As shown, the embodiment of the utility model provides a connection structure for a sputum suction tube flushing device, including an elastic bottle cap 100, a flushing tube 200 and a connecting tube 300; the elastic bottle cap 100 has a bottom opening, a through hole 110 connected to the bottom opening and an annular groove 120 arranged on the inner wall of the bottom opening, the annular groove 120 is used to be adapted and connected with the annular flange on the bottle mouth of the saline bottle, so that the elastic bottle cap 100 is covered on the saline bottle. Specifically, when a certain pressure is applied, a deformation is formed, and it is easy to connect with the saline bottle after deformation. After the connection is completed, the pressure applied to the elastic bottle cap 100 is removed, and the elastic bottle cap 100 is restored to its original state, ensuring the sealing after the annular flange and the annular groove 120 are connected; and when it needs to be removed, a certain force is also applied to the elastic bottle cap 100 to release the connection between the elastic bottle cap 100 and the saline bottle, which is convenient to use and has strong practicality.

[0032] The flushing tube 200 is arranged at the bottom of the elastic bottle cap 100 and one end is connected to one end of the through hole 110, and the other end is provided with a needle tip for inserting into the saline bottle. Specifically, the bottle mouth of the saline bottle is provided with a rubber plug, and the needle tip passes through the rubber plug and extends into the saline bottle to facilitate extraction. At this time, the diameter of the flushing tube 200 is smaller than the diameter of the saline bottle mouth. Of course, the rubber plug can also be removed and the flushing tube 200 can be directly inserted into the bottle body for extraction. At this time, the diameter of the flushing tube 200 is adapted to the saline bottle mouth;

[0033] The connecting tube 300 is arranged on the top of the elastic bottle cap 100 and one end is connected to the other end of the through hole 110, and the other end is used to connect to the suction tube of the suction device. Specifically, under the negative pressure of the suction device, the physiological saline inside the saline bottle can be sucked into the suction tube through the flushing tube 200, the through hole 110 and the connecting tube 300 in sequence, thereby disinfecting and cleaning the inside of the suction tube.

[0034] In the embodiment of the utility model, when in use, the needle tip on the flushing tube 200 is first pierced through the rubber stopper of the saline bottle so that it is located in the saline bottle, and then the elastic bottle cap 100 is placed on the saline bottle, and pressure is applied so that the top of the bottle body extends into the opening of the elastic bottle cap 100, and finally the annular flange and the annular groove 120 are adapted to be connected, so that the elastic bottle cap 100 and the saline bottle are sealed and connected, and the saline bottle will not leak when it is installed inverted or upright. Subsequently, under the negative pressure of the sputum suction device, the physiological saline inside the saline bottle is sucked into the sputum suction tube through the flushing tube 200, the through hole 110 and the connecting tube 300 in turn, and the inside of the sputum suction tube is disinfected and cleaned.

[0035] like Figure 2As shown, in one embodiment of the utility model, the inner wall of the bottom opening of the elastic bottle cap 100 is provided with an inclined surface 130 located below the annular groove 120 and extending to the periphery of the bottom opening of the elastic bottle cap 100. The setting of the inclined surface 130 enables the opening of the tube cap 500 to form a trumpet shape near the bottom position of the elastic bottle cap 100, which can make it easier to cover the elastic bottle cap 100 on the top of the saline bottle, thereby facilitating the connection between the elastic bottle cap 100 and the saline bottle.

[0036] like Figure 2-4 As shown, in an embodiment of the utility model, the flushing tube 200 includes a first tube body 210, a second tube body 220 and a third tube body 230 which are connected in sequence, the first tube body 210 is connected to one end of the through hole 110, and the two ends of the second tube body 220 are respectively connected to one end of the first tube body 210 away from the through hole 110 and one end of the third tube body 230, and a needle tip is provided at one end of the third tube body 230 away from the second tube body 220. By connecting multiple tube bodies, it can meet the needs of saline bottles with different volumes, thereby improving practicality.

[0037] like Figure 2-4 As shown, in the embodiment of the utility model, the second tube body 220 includes an outer tube 221 sleeved on the first tube body 210, an inner tube 222 with two ends respectively arranged in the outer tube 221 and the third tube body 230, and a valve 223 arranged in the outer tube 221, the valve 223 is made of silicone material and can be recessed toward the direction of the connecting tube 300, and a Poisson's cut is arranged on the valve 223. The valve 223 with the Poisson's cut acts as a one-way valve, and the physiological saline can only flow toward the direction of the connecting tube 300 and cannot flow back. Only under the negative pressure of the sputum suction device, the passage will be opened to allow the physiological saline to flow through, otherwise it is in a closed state, and the gravity of the physiological saline in the flushing tube 200 is not enough to open it, so that when the saline bottle is inverted, the physiological saline can be prevented from flowing out by itself.

[0038] like Figure 1-3 As shown, in one embodiment of the utility model, a base 400 is provided at the connection between the connecting tube 300 and the elastic bottle cap 100, and the base 400 is sleeved on the connecting tube 300 and is threadedly connected with a pipe cap 500, and the pipe cap 500 is sleeved on the outlet end of the connecting tube 300. Specifically, an external thread is provided on the outer wall surface of the base 400, and an internal thread is provided on the inner wall surface of the pipe cap 500, and the internal thread and the external thread are correspondingly engaged. Through the engagement of the internal thread and the external thread, after cleaning, the pipe cap 500 can be conveniently screwed, installed and disassembled at the base 400, thereby preventing external dust and impurities from entering the connecting tube 300 and protecting the connecting tube 300 at the same time.

[0039] like Figure 1-3As shown, in one embodiment of the utility model, a connecting rope 600 is provided on the top of the tube cap 500, and the other end of the connecting rope 600 is connected to a swivel 700 provided on the tube cap 500, and the swivel 700 rotates on the tube cap 500. When cleaning is required, the tube cap 500 is rotated to remove the connecting tube 300, so that the connecting tube 300 is connected to the pipeline of the sputum suction device. At this time, the tube cap 500 is also located on the tube cap 500 under the action of the connecting rope 600. When cleaning is completed, the tube cap 500 is tightened on the connecting tube 300 for easy use.

[0040] like Figure 1 As shown, in one embodiment of the utility model, an operating portion is provided on the tube cap 500, and a plurality of anti-slip patterns and / or anti-slip grooves are provided on the operating portion. With the cooperation of the operating portion and the anti-slip patterns or anti-slip grooves, it is convenient to manually rotate the tube cap 500 to avoid slipping that affects the operation.

[0041] like Figure 2-3 As shown, in one embodiment of the utility model, the inner top wall of the pipe cap 500 is provided with a block 800 which cooperates with the outlet end of the connecting pipe 300 for sealing. After cleaning, the pipe cap 500 is screwed onto the connecting pipe 300, and the block 800 is inserted into the connecting pipe 300 to further ensure the cleanliness of the inside of the connecting pipe 300.

[0042] In one embodiment of the utility model, the elastic bottle cap 100 and the blocking block 800 are both made of silicone material. The silicone material has good toughness and strong recovery ability after deformation. The one-piece molding method is beneficial to ensuring the consistency of product quality and reducing manufacturing costs.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
