[0029] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0030] like Figure 1As shown, a disposable sputum culture bottle includes a bottle body 1 and a bottle cap 2 installed at the top opening of the bottle body 1. A suction connecting tube 3 for connecting a suction tube 7 is installed on the bottle cap 2. The lower end of the suction connecting tube 3 extends into the bottle body 1 and is interconnected. A clamping mechanism is installed inside the suction connecting tube 3. The discharge end of the suction tube 7 is inserted into the suction connecting tube 3 and fastened by the clamping mechanism. By installing the clamping mechanism inside the suction connecting tube 3, the discharge ends of suction tubes 7 of different diameters can be clamped and fixed.
[0031] The upper end of the suction connecting tube 3 is located outside the bottle cap 2 and is equipped with a sealing element. The sealing element seals the gap between the upper opening of the suction connecting tube 3 and the outer wall of the suction tube 7, so as to ensure the sealing of negative pressure suction when using suction tubes 7 of different diameters. This makes it suitable for patients of all ages, bringing convenience to actual suctioning operations and has broad market prospects.
[0032] The bottle cap 2 is equipped with a negative pressure connecting pipe 4 for connecting to the negative pressure pipe 6. The inner wall of the upper opening of the negative pressure connecting pipe 4 has an internal thread, and the suction end of the negative pressure pipe 6 has an external thread that engages with the thread of the negative pressure connecting pipe 4, which facilitates actual pipeline connection and sealing.
[0033] Specifically, such as Figure 4 and Figure 5 As shown, the clamping mechanism includes multiple clamping plates 9, which are evenly distributed circumferentially along the inner wall of the suction connecting tube 3 to form a binding ring that matches the discharge end of the suction tube 7. The gap between the clamping plates 9 and the inner wall of the suction connecting tube 3 is adjustable. By adjusting the gap between the clamping plates 9 and the inner wall of the suction connecting tube 3, the inner diameter of the binding ring can be adjusted, thereby facilitating the clamping of suction tubes 7 of different diameters.
[0034] Furthermore, the clamping mechanism also includes springs 10, the number of springs 10 is the same as the number of clamps 9 and they correspond one-to-one. One end of the spring 10 is fixedly connected to the inner wall of the suction connecting tube 3, and the other end of the spring 10 is fixedly connected to the outer side of the corresponding clamp 9. The clamp 9 is connected to the inner wall of the suction connecting tube 3 through the spring 10. By utilizing the elastic deformation of the spring 10, the clamp 9 can be elastically extended and retracted so as to adaptively adjust to suction tubes 7 of different diameters.
[0035] Furthermore, the inner surface of the splint 9 is arc-shaped and fits against the outer wall of the drainage end of the suction tube 7, which can improve the fit between the splint 9 and the outer wall of the suction tube 7, thereby improving the actual clamping stability.
[0036] Furthermore, the upper end of the clamp 9 is designed with a slope, and the bottom end of the slope is set towards the axis of the suction connecting tube 3. When the suction tube 7 is inserted into the suction connecting tube 3, the lower end of the suction tube 7 contacts the slope of the upper end of the clamp 9, thereby squeezing the clamp 9 outward so that the lower end of the suction tube 7 can be inserted between multiple clamps 9, thereby better adaptively clamping suction tubes 7 of different thicknesses.
[0037] Furthermore, the clamp 9 is made of rubber, silicone or plastic, which can increase the friction between the clamp 9 and the outer wall of the suction tube 7, thereby improving the clamping stability of the suction tube 7.
[0038] Specifically, such as Figures 2-4 As shown, the sealing component includes a sealing tube 5 and a sealing ring 8. The sealing tube 5 is installed at the upper end of the suction connecting tube 3 and is located above the bottle cap 2. The lower end of the sealing tube 5 is threadedly connected to the upper end of the suction connecting tube 3 for easy disassembly and replacement. The sealing ring 8 is set in the upper opening of the sealing tube 5, and the outer wall of the sealing ring 8 is fixedly connected to the inner wall of the sealing tube 5. The discharge end of the suction tube 7 passes through the sealing tube 5 and is inserted into the suction connecting tube 3. The outer wall of the suction tube 7 is tightly fitted with the inner wall of the sealing ring 8. The sealing ring 8 is used to seal the tube to ensure the actual negative pressure sealing effect.
[0039] Furthermore, the inner wall of the sealing ring 8 has multiple lips that are spaced apart along the axial direction of the sealing ring 8. Through the multi-lip sealing design of the sealing ring 8, multiple seals can be formed inside the upper end of the sealing tube 5, thereby improving the actual sealing performance.
[0040] Furthermore, such as Figure 2 As shown, the sealing ring 8 has five lips, which are designated as the first lip, second lip, third lip, fourth lip, and fifth lip from top to bottom. The inner diameters of the first lip, second lip, and third lip gradually decrease, while the inner diameters of the third lip, fourth lip, and fifth lip gradually increase, in order to seal suction tubes 7 of different diameters.
[0041] like Figure 4 As shown, when the outer diameter of the suction tube 7 is greater than the inner diameter of the first lip, after the suction tube 7 is inserted into the sealing tube 5, the lower end of the suction tube 7 will press down on the first lip, the second lip, and the third lip, causing the first lip, the second lip, and the third lip to all turn downwards, increasing the contact area between the lip and the suction tube 7, thereby improving the actual sealing effect. Similarly, when the outer diameter of the suction tube 7 is greater than the inner diameter of the fifth lip, the third lip, the fourth lip, and the fifth lip also turn downwards, further improving the sealing effect.
[0042] The technical features of the above embodiments can be combined in any way (as long as there is no contradiction in the combination of these technical features). For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described; these embodiments not explicitly written should also be considered to be within the scope of this specification.
