Description

Technical Field

[0001] The utility model belongs to the technical field of drainage bottles, and in particular relates to an anti-overflow negative pressure drainage bottle for smoking liquid absorption. Background Art

[0002] In clinical practice, negative pressure drains, also known as suction bottles, are generally used in operating rooms and wards. They are mainly used to absorb liquids and smoke during surgery, as well as discharge sputum, medical drainage, dirty blood and secretions in wards and other scenes. Negative pressure drains use the principle of vacuum to generate negative pressure in the human body's cavity, thereby guiding the liquid in the cavity and playing its role in drainage and purification.

[0003] The negative pressure aspirator is mainly composed of a hose and a liquid collection bottle. There are two hose connection ports on the liquid collection bottle, one of which is connected to the working chamber and the other is connected to the negative pressure terminal. When it is connected to the negative pressure terminal, negative air pressure will be generated in the liquid collection bottle, and this negative pressure will guide sputum, secretions or dirty blood, etc., through the drainage of another hose, into the liquid collection bottle.

[0004] However, the existing liquid collecting bottle still has the following problems during the drainage process:

[0005] The existing drainage bottle can only guide the liquid in the cavity, but the smoke removal effect is very poor. The smoke quickly gathers in the drainage bottle and cannot dissipate after it is full, resulting in increased pressure in the bottle. The liquid and smoke cannot be sucked away any more, and the drainage bottle can only be replaced. However, as a consumable, the drainage bottle is difficult to replace frequently. Therefore, the diffuse smoke affects the surgical process, is detrimental to the operating room environment, and poses a threat to the health of personnel in the operating room.

DETAILED DESCRIPTION

[0034] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention. Embodiment 1:

[0035] Refer to the attached Figure 1-5 , an anti-overflow negative pressure drainage bottle for smoking liquid absorption, comprising a drainage bottle body 1, an upper end of the drainage bottle body 1 is provided with an external thread, and a rubber ring 3 is embedded in the end surface at the edge;

[0036] Also includes:

[0037] The filter cover 2 has an inner wall at the bottom thereof provided with an inner thread matched with the outer thread of the upper port of the drainage bottle body 1. After being tightened, the rubber ring 3 can seal and prevent the leakage of smoke.

[0038] A plurality of vertical partition plates 5 are bonded or integrally formed inside the filter cover 2 to divide the space into equal parts;

[0039] A drainage tube 4 is arranged at the center of the partition plate 5, which plays a supporting role on the one hand, and drains the fluid on the other hand.

[0040] The gap between the partition plates 5 is provided with a filter assembly;

[0041] The filter components include:

[0042] The non-woven fabric layer 6 is a multi-layer non-woven fabric layer 6 bonded to the bottom layer of each partition plate 5. The non-woven fabric layer 6 can absorb the smoke in the gas and filter the dust particles with relatively large diameters. On the other hand, it can also play a role of wrapping and supporting, and can carry the activated carbon on the upper layer.

[0043] Activated carbon layer 7, the activated carbon layer 7 is arranged in the space formed by the non-woven fabric layer 6 and the partition plate 5, and the activated carbon can well absorb particles and gases with smaller particle sizes in the flue gas;

[0044] The negative pressure pipe 11 and the upper end of the partition plate 5 are bonded with a sealing plate 8 , and the function of the sealing plate 8 is to completely encapsulate the activated carbon in the gap of the partition plate 5 .

[0045] The upper end surface of the sealing plate 8 is provided with a short tube 9 corresponding to each area of ​​the partition plate 5, that is, each space isolated by the partition plate 5 is provided with a short tube 9 on the upper end surface of the corresponding sealing plate 8. In order to avoid the activated carbon from being sucked into the negative pressure condition, a filter can be set in the short tube 9 to prevent the activated carbon from being sucked into the negative pressure pipeline. The short tube 9 is connected to the negative pressure pipe 11 through the conduit 10.

[0046] The upper layer of the sealing plate 8 is the upper end surface of the filter cover 2, and the upper ends of the negative pressure tube 11 and the drainage tube 4 are protrudingly arranged to facilitate the connection between the negative pressure terminal and the cavity tube.

[0047] Usage and principle:

[0048] When in use, the filter cap 2 is connected to the drainage bottle body 1, the negative pressure tube 11 is connected to the negative pressure terminal to provide a negative pressure environment, the drainage tube 4 is connected to the cavity tube, and the tissue fluid and smoke in the inner cavity are attracted, and then the tissue fluid and smoke enter the drainage bottle body 1, and the smoke is filtered by the non-woven fabric layer 6 and the activated carbon layer 7 in turn, and finally the clean gas passes through the short tube 9, the catheter 10 and the negative pressure tube 11, thereby achieving the effect of drainage and filtration.

[0049] Embodiment: 2:

[0050] Based on Example 1, Figure 6-7 , this embodiment is provided with an anti-overflow component;

[0051] A thick tube 401 is formed at the lower end of the drainage tube 4 . The diameter of the thick tube 401 is larger than the normal diameter of the drainage tube 4 . The anti-overflow component is arranged in the thick tube 401 .

[0052] The anti-overflow kit includes:

[0053] The overflow plate 402 is bonded to the upper part of the thick tube 401 and has a through hole 408 in the center. The diameter of the through hole 408 is slightly smaller than the diameter of the drainage tube 4, so that the drainage can be smooth.

[0054] A limit block 403 is fixedly arranged in the middle of the thick tube 401. A sliding hole 405 is provided in the center of the limit block 403. Four drainage holes 404 are provided on the periphery of the sliding hole 405. The arrangement of the drainage holes 404 can ensure the smooth suction of the drainage fluid.

[0055] The hollow valve body 406 is similar to the "I"-shaped structure, and is made of lightweight plastic. The hollow airbag 407 is inside, so that the hollow valve body 406 is arranged in the sliding hole 405. The diameter of the upper end surface is larger than the diameter of the through hole 408, and the through hole 408 can be completely blocked. The diameter of the lower end is also larger than the diameter of the through hole 408, and it can have greater buoyancy, so that its upper end surface can completely block the through hole 408.

[0056] Usage and principle:

[0057] When in use, the drainage fluid enters the drainage bottle body 1 from the through hole 408 and the drainage hole 404. When the drainage fluid is about to reach the rated scale, the buoyancy of the liquid surface lifts the hollow valve body 406, thereby completely blocking the through hole 408 to achieve closure and avoid backflow of the drainage fluid.

[0058] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
