In summary, the application includes the following beneficial effects:

1. The utility model uses a sampling port on the upper end of the drainage bottle, which can facilitate sampling and keep the sample out of contact with the air, so as to ensure the sterility of the sample and the accuracy of the sampling test result.

2. By setting the sampling device, the utility model can directly sample the effusion in the drainage bottle through the sampling tube without affecting the use of the drainage bottle, reducing the risk of pollution, and at the same time it is convenient to take samples in real time, ensuring that patients can be kept informed at any time Health status.

3. The utility model is equipped with a sealing cover for sealing the sampling port, ensuring that the drainage bottle is in a closed environment during normal use, and preventing gas from entering the sampling bottle and contaminating the drainage liquid.

4. The utility model adopts a one-way valve structure in the sampling channel to ensure that when the sampling port of the drainage bottle is in an open state, air will not enter the sampling bottle from the sampling port and pollute the drainage liquid.

Detailed ways

The present application will be described in further detail below in conjunction with accompanying drawings 1-5.

The embodiment of the present application discloses a drainage bottle 1 that can be sampled, including the drainage bottle 1 itself, and a sampling port 2 is provided through the upper end cover of the drainage bottle 1 itself, so that sampling can be performed without affecting the normal drainage of the drainage bottle 1, A sampling device 3 is detachably installed at the sampling port 2. The sampling device 3 includes a connecting end 4 and a sampling tube 5 communicated with each other. The connecting end 4 is provided with a screw thread 8 on the outer wall fitted with the sampling port 2. It is connected with the sampling port 2 through the thread 8, which is suitable for the clinical use of the drainage bottle 1. For severe patients who need real-time sampling, the sampling device 3 can be installed on the sampling port 2 to facilitate sampling. For some mild patients, real-time sampling may not be required. When sampling or sampling is not required, the sampling device 3 can be removed and used as a normal drainage bottle 1 .

The connecting end 4 of the sampling device 3 and the sampling tube 5 are connected to each other. In order to facilitate production, the sampling tube 5 and the connecting end 4 can be integrally formed or split into a plug-in structure. The opening is used for inserting the sampler 10, and the sampler 10 can adopt an extractable device similar to a syringe, and the drainage fluid in the suction bottle can be extracted through the sampler 10 as a sample.

The sampling tube 5 is installed through the connection end 4 and the sampling port 2. It is completely accommodated inside the drainage bottle 1, and its end away from the connection end 4 extends to the bottom of the drainage bottle 1, no matter how much fluid in the drainage bottle 1 is. It is ensured that the sampler 10 is capable of sampling, and the sampling is liquid accumulation at the bottom of the drainage bottle 1 , which does not affect the normal drainage work of the drainage bottle 1 .

Preferably in the utility model, the inner diameter of the sampling tube 5 is 0.7mm-1.5mm, the inner diameter of the sampling tube 5 of the smallest specification can be used, and the length of the sampling tube 5 can be adapted to meet the requirement that it can reach the bottom of the drainage bottle 1, while ensuring that the sampler 10 Extract the effusion within the minimum extraction stroke.

In order to ensure the airtightness of the drainage bottle 1, a sealing cover 6 is provided at the sampling port 2, and its sampling port 2 is in a sealed state all the time when sampling is not needed. Preferably, the aperture of the opening provided by the connection end 4 of the sampling device 3 is the same The caliber of the sampling port 2 is the same. After the sampling device 3 is installed on the sampling port 2, its sealing cover 6 can be adapted to seal the sampling opening, so as to further ensure the airtightness of the drainage bottle 1 without affecting its normal operation.

A connecting rib 7 is connected between the sealing cover 6 and the sampling port 2, and the sampling port 2 extends upwards along the upper end cover of the drainage bottle 1 itself to form a first-order installation platform. One end of the connecting rib 7 is fixed on the installation platform, and the other end is fixed on the On the sealing cover 6, a conjoined structure is adopted between the sealing cover 6 and the sampling port 2 to ensure that after opening, the sealing cover 6 can be directly hung on the sampling port 2, and the sealing cover 6 does not need to be held by hand or placed separately, which can avoid misplacement Cause sealing cap 6 to lose, and its sealing cap 6 can adopt push-type structure or screw thread 8 connection structure and sampling port 2 or opening sealing fit, also can adopt existing flip-top bottle cap.

In order to ensure that after the sealing cover 6 is opened, air will not enter the drainage bottle 1 from the sampling opening to cause pollution during the sampling process. There are several valves 9, and several valves 9 are evenly distributed on both sides of the passage, and several valves 9 are arranged along the flow direction of the sampling liquid, so that the passage of the connection end 4 is in an open state along the flow direction of the sampling liquid, otherwise it is in a closed state , can play a role of one-way blocking air circulation, and ensure the aseptic state in the drainage bottle 1 .

The structure of the valve 9 is similar to the structure of an arterial valve. When the effusion is drawn into the syringe along the sampling tube 5, the valve 9 in the channel of the connecting end 4 at this time is in an upward position as a whole and is squeezed and opened. If it is reversed When air is fed into the drainage bottle 1 from the outside, due to the orientation of the valve 9 opening, the air will extrude the valve 9 to make its two sides interfere with each other, so that the valve 9 opening is in a closed state, and air cannot enter the drainage bottle 1.

All of the above are preferred embodiments of the present application, and are not intended to limit the protection scope of the application. Therefore, all equivalent changes made according to the structure, shape and principle of the application should be covered by the protection scope of the application. Inside.
