Embodiment 1

[0023] A hematoma remover, comprising a suction device 1, a negative pressure suction device connected to the suction device 1, and a rotating device 6. The negative pressure suction device includes a filter 2, a circulating pump 3 and corresponding connecting pipes, and the suction device 1 is connected to the filter 2. The filter 2 is connected to the circulating pump 3, and the circulating pump 3 is connected to the suction device 1 to form a closed-loop path. The entire closed-loop path is filled with working fluid. Both the circulating pump 3 and the rotating device 6 are controlled by the electrical control unit 5. The suction device 1 includes a rotor 11 and The stator 12 and the stator 12 are fixed. The front end of the rotor 11 protrudes from the front end of the stator 12 and can rotate in the stator 12. The front end of the rotor 11 is provided with a number of spray holes 113, and the corresponding end of the stator 12 is provided with suction holes 121. The end is c...

Embodiment 2

[0033] When there is a hematoma in the bladder of a patient clinically, the hematoma remover of the present invention can also be used to remove hematoma, such as figure 2 As shown, on the basis of the structure of the first embodiment above, an airbag fixing device 9 is fitted on the outer wall of the stator 12. The airbag fixing device 9 includes an airbag 91, an inflation tube 92 and an inflation valve 93. It is not convenient to fix and attract the bladder due to the operation. Therefore, the aspirator is equipped with an airbag fixing device. During the operation, after the aspirator 1 is placed in the bladder, gas or liquid is injected through the inflation valve 93, the airbag 91 is inflated through the inflation pipe 92, and the airbag is used to fix the aspirator The surgical procedure is the same as that of the first embodiment, and will not be repeated. In order to adapt to the internal cavity, the suction device can be made into a flexible structure.

Abstract

The invention provides a hematoma remover, which can solve the problems that in the prior art, the suction efficiency is low, the aseptic process is difficult to realize, the manufacturing process is complex, and the pipe diameter of a suction apparatus is large. The invention adopts the technical scheme that the hematoma remover comprises the suction apparatus, a negative pressure suction device connected with the suction apparatus, and a rotating device, wherein the negative pressure suction device comprises a filter, a circulating pump and corresponding connecting pipelines; a closed-loop channel is formed by the negative pressure suction device and the suction apparatus; the whole closed-loop channel is filled with operating fluid; both the circulating pump and the rotating device are controlled by an electric appliance control unit; the suction apparatus comprises a rotor and a stator; the stator is fixed; the rotor is rotated in the stator; the rear end of the rotor is connected with the rotating device; a screw blade is arranged on the outer wall of the rotor; the filter is communicated with the inner cavity of the stator; and the circulating pump is communicated with the inner cavity of the rotor. By improving the structure of the suction apparatus, the rotor replaces the conventional rotating shaft and is provided with the screw blade, the outer diameter of the suction apparatus is reduced, the suction efficiency is improved, and the structure is simplified.

Description

Technical field [0001] The invention belongs to the field of medical devices, and specifically relates to a hematoma remover for clinical application. Background technique [0002] At present, in the treatment of cerebral hemorrhage, intracranial hematoma crushing and aspiration technology is usually used clinically. This technology uses a suction device to cut and smash the hematoma and suck it out. The aspirator is also connected to a balanced lavage device under continuous negative pressure. After filtration, it is injected into the skull at the same time to keep the volume of the hematoma cavity unchanged and achieve the purpose of removing the hematoma. Otherwise, the intracranial pressure will change, which will easily cause brain tissue damage. [0003] But the hematoma remover usually used clinically, the suction device is a non-concentric double-layer tubular structure, including an outer tube and an inner tube. The outer tube is filled with working fluid, and the front en...
