Hematoma remover

Abstract

The invention discloses a hematoma remover, which is characterized by comprising an aspirator and a double-container balanced lavaging device, wherein the aspirator comprises a high pressure cavity and a low pressure cavity; the double-container balanced lavaging device comprises a liquid inlet pipeline, a liquid outlet pipeline, a No.1 pump, a No.2 pump, a No.1 container and a No.2 container; the No.1 container is connected to the high pressure cavity of the aspirator through the liquid inlet pipeline and the No.1 pump; the low pressure cavity of the aspirator is connected to the No.2 container through the liquid outlet pipeline and the No.2 pump; the No.1 container is provided with a No.1 metering sensor; the No.2 container is provided with a No.2 metering sensor; the No.1 pump and the No.2 pump are respectively provided with a central controller capable of controlling the running state of the pumps; and the No.1 metering sensor and the No.2 metering sensor are connected to the central controller. The work efficiency of the two pumps is dynamically regulated by the central controller, the requirement of fulfilling surgical tasks such as intracranial hematoma is met, and defects of high operating and maintenance cost and the like of the conventional hematoma remover can be overcome.

Description

technical field [0001] The invention relates to a hematoma evacuator in medical equipment. Background technique [0002] Currently, in the treatment of cerebral hemorrhage, a hematoma evacuator is usually used clinically. The hematoma evacuator includes a suction device and a balance lavage device connected with the suction device. The above-mentioned suction device is a double-chamber suction device, including a high-pressure chamber and a low-pressure chamber; the above-mentioned balanced irrigation device includes a high-pressure pipeline, a low-pressure pipeline, a circulation pump, a filter and an exhaust device, wherein the circulation pump is connected to the high-pressure pipeline through a high-pressure pipeline. The high-pressure chamber of the suction device, the filter exhaust device is connected to the high-pressure or low-pressure pipeline, the low-pressure chamber of the suction device is connected to the circulation pump through the low-pressure pipeline, an...

AI Technical Summary

Problems solved by technology

Although the above-mentioned hematoma evacuator can complete intracranial hematoma and other surgical tasks, it also has deficiencies, which are mainly manifested in: due to the continuous circulation of working fluid, the probability of infection is increased, and the requirements for filters and exhaust devices are relatively high, resulting in The disadvantage is that the operation and maintenance costs are high; it is difficult to find the disadvantages such as active bleeding
