detailed description

Referring to Figure 1, a hematoma remover includes an aspirator 1 and a dual container balanced lavage device coupled to the aspirator. The above suction device includes a high pressure chamber and a low pressure chamber. The above-mentioned double-container balanced lavage device comprises a liquid inlet pipe 2, a liquid outlet pipe 3, a first pump 4, a second pump 5, a first container 6 and a second container 7. The first container is connected to the high pressure chamber of the suction device through the liquid inlet pipe and the first pump, and the low pressure chamber of the suction device is connected to the second container through the liquid outlet pipe and the second pump. The first container is equipped with a measuring sensor No. 1, and the second container is equipped with a second measuring sensor 9; each measuring sensor can be equipped with a sensor capable of measuring the weight or volume of the working fluid in the container. The first pump and the second pump are provided with a central controller 10 capable of controlling the operating state of each pump, and the first measuring sensor and the second measuring sensor are connected to the central controller.

In the above manner, a pressure sensor 11 may be disposed on the liquid inlet pipe between the first pump and the high pressure chamber of the suction device, and the outlet pipe between the low pressure chamber of the suction device and the second pump is provided with two No. Pressure sensor 12; -, No. 2 pressure sensor is connected to the above central controller. Used for dynamic monitoring of working fluids.

The working principle and manner of the present invention can be roughly as follows:

When the hematoma remover is started, the central controller first obtains the initial measurement values of the working fluids in the first and second containers through the first and second measuring sensors, respectively, and sets them to a0 and b0, respectively, and controls the first pump and the second. The pump starts to run; then the central controller obtains the measured values of the working fluids in the first and second containers through the first and second measuring sensors in real time, and sets them as al and bl respectively, and compares them with the corresponding initial measured values. The values are set to Δ ₃ and A b, respectively, SP : Δ a = al - a0, A b = b l - b0. In order to ensure that the amount of working fluid discharged from the aspirator into the hemorrhage per unit time is the same, the above 3 and 1) should be equal in theory (same), in actual operation, the difference between the two is controlled within the set range. can. The central controller adjusts the pumping capacity (working efficiency) of the No. 1 pump and the No. 2 pump per unit time by comparing the sum value. If the difference between the two is within the set range, continue the working efficiency of the current two pumps (station); if A a is greater than A b and the difference is outside the set range, then control the No. 1 pump (station) The working efficiency is lower than that of the second pump (station); vice versa.

Through the above control adjustment, it can be carried out in a sufficiently dense time unit, and the working fluid correction page of the inlet and outlet suction can be realized (Article 91) ISA/CN Approximate equivalent.

In addition, the central controller can control the replacement efficiency of the working fluid in the hematoma cavity by controlling the working efficiency of the No. 1 pump and the No. 2 pump. And by the central controller, by working one of the No. 1 pump and the No. 2 pump, the amount of working fluid in the hematoma cavity can be changed.

The related technical content not mentioned in the above manner can be realized by referring to the prior art.

It should be noted that those skilled in the art can also make one or the other easily changeable manners, such as equivalents, or obvious variations, in the teachings of the present specification. The above variations are all within the scope of the present invention.
