For example, "front" information may also be referred to as "rear" information, and "rear" information may also be referred to as "front" information without departing from the scope of the present invention.

As shown in Figure 1, the utility model provides a double negative pressure drainage device, which includes a drainage bottle 1, a drainage tube 2, a pressurized syringe 3 and a collecting bottle 6. Specifically, the drainage bottle 1 is made of a flexible material, and its bottle body is provided with a first interface, a second interface and a third interface connected to the outside world. The first interface of the drainage bottle 1 is fixedly connected to the drainage tube 2, and the other end of the drainage tube 2 is inserted into the patient's body to guide the body fluid produced by the patient into the drainage bottle 1; further, the second interface of the drainage bottle 1 is fixedly connected with the pressurized syringe 3, and when the pressurized syringe 3 is in the initial state, its rubber plug is pushed into the syringe tube body, that is, the medical staff can extract the air in the drainage bottle 1 by pulling the rubber plug to further reduce the pressure in the drainage bottle 1 and enhance the negative pressure effect; further, the third interface of the drainage bottle 1 is connected to the collecting bottle 6, and the drainage fluid that reaches the drainage bottle 1 through the drainage tube 2 can continue to reach the collecting bottle 6 through the third interface, so as to realize the storage of the drainage fluid and avoid the accumulation of liquid in the drainage bottle 1 affecting the drainage effect.

Based on the above structure, when in use, the medical staff closes the third interface and squeezes the drainage bottle 1. The drainage bottle 1 made of flexible material is deformed due to squeezing, and the gas in the drainage bottle 1 is discharged through the first interface. A first negative pressure is formed in the drainage bottle 1. Then, the rubber plug of the pressurized syringe 3 is operated to move outward to extract the air in the drainage bottle 1 to form a second negative pressure. After ensuring the negative pressure in the bottle, the first interface is opened, and the drainage fluid in the drainage tube 2 flows into the drainage bottle 1 under the action of negative pressure. The drainage fluid entering the drainage bottle 1 continues to flow and reaches the collecting bottle 6 through the third interface to achieve effective collection and storage. In this way, the present application forms multiple negative pressures by setting a pressurized syringe 3 to squeeze the drainage bottle 1, which greatly increases the negative pressure suction effect of the drainage bottle 1, avoids the operation of repeatedly squeezing the drainage bottle 1, and improves the drainage effect; the present application connects a collecting bottle 6 to the drainage bottle 1 to collect the drainage fluid in the drainage bottle 1. The volume of the collecting bottle 6 is much larger than the volume of the drainage bottle 1, which avoids repeated discharge caused by the accumulation of drainage fluid in the drainage bottle 1, and ensures the continuous drainage.

Optionally, in some embodiments of the present application, the dual negative pressure drainage device includes a barometer, which is provided on the drainage bottle 1 and connected to the internal space of the drainage bottle 1. Based on the above structure, the present application monitors the pressure condition in the drainage bottle 1 in real time by setting a barometer, and medical staff can clarify subsequent operations according to the pressure condition. Furthermore, the barometer of the present application is provided with an alarm device. When the pressure in the drainage bottle 1 reaches a predetermined value, the alarm device will automatically issue a warning to remind medical staff to discharge the drainage fluid in the drainage bottle 1 in time, thereby ensuring the normal drainage.

Furthermore, in some embodiments of the present application, the drainage bottle 1 is provided with a fourth interface, and the fourth interface is provided with a flushing knob 4. Based on the above structure, when the drainage is completed, the medical staff can unscrew the flushing knob 4 on the fourth interface and inject a cleaning liquid into the drainage bottle 1 through the fourth interface. The cleaning liquid enters the drainage bottle 1 through the fourth interface to clean the drainage bottle 1 and finally flows out through the third interface. The setting of the fourth interface and the flushing knob 4 simplifies the cleaning steps and realizes the rapid cleaning of the drainage bottle 1. When the cleaning is completed, the flushing knob 4 on the fourth interface is tightened again to ensure the overall sealing of the drainage bottle 1.

Optionally, in some embodiments of the present application, a first scale is provided on the pressurized syringe 3. Based on the above structure, medical staff can determine the specific suction volume according to the first scale on the pressurized syringe 3 to enhance the negative pressure enhanced drainage effect.

Similar to the first scale, in some embodiments of the present application, a second scale is provided on the collecting bottle 6. Different from the first scale, the second scale on the collecting bottle 6 is used to display the storage status of the drainage fluid in the bottle, and the medical staff can directly read the drainage volume of the patient in one day through the second scale, which is convenient for the medical staff to monitor the patient's condition.

Furthermore, the drainage bottle 1 of the present application is connected to the collecting bottle 6 via a transfer tube 7, and a valve 8 is provided on the transfer tube 7 to control the connection between the drainage bottle 1 and the collecting bottle 6 to achieve controlled discharge of the drainage fluid.

Furthermore, in some embodiments of the present application, a bottle cap 9 is screwed on the top of the collection bottle 6, and the transfer tube 7 passes through the bottle cap 9 to reach the collection bottle 6. Based on the above structure, the present application sets a detachable bottle cap 9 to seal the collection bottle 6. After the drainage is completed, the bottle cap 9 can be unscrewed and the drainage liquid in the collection bottle 6 can be poured out, thereby realizing the recycling of the collection bottle 6.

In summary, the utility model provides a double negative pressure drainage device, which includes a drainage bottle 1, a drainage tube 2, a pressurized syringe 3 and a collecting bottle 6. The drainage bottle 1 is made of a flexible material, the drainage tube 2 and the collecting bottle 6 are connected to the drainage bottle 1, and the pressurized syringe 3 is connected to the drainage bottle 1 to draw out the air in the drainage bottle 1. In this way, the present application forms multiple negative pressures by setting the pressurized syringe 3 to cooperate with squeezing the drainage bottle 1, which greatly increases the negative pressure suction effect of the drainage bottle 1, avoids the operation of repeatedly squeezing the drainage bottle 1, and improves the drainage effect; the present application connects the collecting bottle 6 to the drainage bottle 1 to collect the drainage fluid in the drainage bottle 1, and the volume of the collecting bottle 6 is much larger than the volume of the drainage bottle 1, which avoids repeated discharge caused by the accumulation of drainage fluid in the drainage bottle 1, and ensures the continuous drainage.

The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
