Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the present invention will be further described in detail with reference to the specific embodiments.

As shown in figure 1, the utility model comprises an infusion device and a drainage device; the device also comprises a pulse device which is connected with the infusion device and generates pulse water flow, wherein a liquid outlet of the infusion device is connected with the pulse device, and a water outlet pipe 42 of the pulse device is connected with the abdominal cavity of the patient; the liquid inlet of the drainage device is connected with the abdominal cavity of the patient.

Specifically, the infusion set comprises a saline bag 1 and a conduit connected to a pulse device, the conduit being provided with a restrictor 2. The drainage device comprises a drainage bottle 8, the top of the drainage bottle 8 is provided with a liquid inlet connected with the abdominal cavity of the patient, and the bottom of the drainage bottle 8 is provided with a liquid outlet connected with a waste liquid bag 10; the drainage bottle also comprises a floating plug 9 which is arranged in the drainage bottle 8 and used for plugging the liquid outlet.

The pulse device comprises a tank body 3, wherein an inverted U-shaped drainage tube 4 is arranged in the tank body 3; one end of the drainage tube is a water inlet tube 41, and the other end of the drainage tube is a water outlet tube 42, one end of the water inlet tube 41 is positioned in the tank body 3, and the other end of the water outlet tube 42 penetrates through the bottom of the tank body 1 and extends out of the tank body 1; the water tank also comprises an exhaust pipe 5, wherein one end of the exhaust pipe 5 penetrates through the bottom of the tank body 3 and extends out of the tank body 3, and the other end of the exhaust pipe is communicated with the middle part of the water inlet pipe 41; the drainage device further comprises an exhaust branch pipe 6, wherein the upper end of the exhaust branch pipe 6 is communicated with the top end of the drainage pipe 4, and the lower end of the exhaust branch pipe is communicated with the middle of the exhaust pipe 5. The top of the tank body 1 is provided with a vent pipe communicated with the atmosphere. And the liquid collecting bag 7 is connected with one end of the exhaust pipe 5 extending out of the tank body 1.

Of course, other types of pulse devices may be used as long as they can generate a pulsed water flow.

When in use, the water outlet pipe 42 of the pulse device enters the abdominal cavity from the head side of the patient, and the liquid inlet of the drainage device is connected with the abdominal cavity from the tail side of the patient. The patient is preferably in a semi-slope lying position.

The saline water bag 1 continuously injects water into the tank body 3, when the liquid level rises to reach the upper end of the exhaust pipe 5, saline water enters the exhaust pipe 5 from the upper end opening of the exhaust pipe 5 and flows out from the lower end opening of the exhaust pipe 5; in the process, the air in the draft tube 4 continuously enters the exhaust pipe 5 from the exhaust branch pipe 6 and is exhausted, so that negative pressure is formed inside the throttle tube 4; when the liquid level reaches the top of the draft tube 4, the brine enters one end of the outlet tube 42 of the draft tube 4. At the moment, the saline water continuously enters the throttling pipe 4 from the tank body 3 under the action of the atmospheric pressure to form a siphon phenomenon, so that the flushing is started. When the liquid level in the tank body 3 is lower than the lower end of the water inlet pipe 41 of the throttle pipe 4, the siphon condition is destroyed, the siphon is stopped, and the next pulse period is entered. It is expected that the rate of refilling the tank 3 with infusion set is much less than the rate of draining the tank 3.

During drainage, the negative pressure in the drainage bottle 8 can suck the liquid in the abdominal cavity of the patient into the drainage bottle 8 together with food residues, pus and the like and collect the liquid through the waste liquid bag 10. When the pipeline is blocked, the liquid level of the drainage bottle 8 is reduced, and the floating plug 9 can plug the outlet of the drainage bottle 8 to avoid the negative pressure environment in the drainage bottle 8 from being damaged by the atmosphere communication.
