Description

Technical Field

[0001] This utility model relates to the field of medical devices, specifically an aspirator. Background Technology

[0002] During surgery or wound treatment, patients produce a mixture of bodily fluids, including blood, other bodily fluids, and bacteria. Medical staff need to aspirate this pus, often using a suction device to remove it and prevent interference with surgery or other nursing procedures. A suction device disclosed in application CN202322234761.0 describes a device comprising a sleeve, a piston slidably mounted inside the sleeve, a threaded sleeve fixedly mounted on the piston, a reciprocating lifting component mounted on the threaded sleeve, and a driving component mounted between one side of the reciprocating lifting component and the sleeve. The driving component drives the reciprocating lifting component to move, causing the piston to slide back and forth along the axial direction of the sleeve. It also includes a gear assembly mounted on... On the threaded sleeve, the gear assembly and the drive component are connected by a transmission component. The transmission component drives the gear assembly to rotate, causing the threaded sleeve to rotate. After one reciprocating lifting and lowering motion, the initial position of the piston changes. The reciprocating lifting and lowering component changes the initial height of the piston after one complete suction and discharge process, and the height difference of the piston rises decreases, so that the amount of pus suctioned by the device decreases sequentially, avoiding the device from accidentally aspirating the patient's normal bodily fluids. However, the above description still has the following defects in actual use: the suction device lacks the function of changing its own suction force, making it difficult to use during surgery or nursing. At the same time, it is not convenient to adjust the suction force of the tube cavity. Therefore, a more practical suction device needs to be designed. Utility Model Content

When aspirating liquid, the elastic frames 24 are released. During the process of the airbag 22 returning to its original shape, liquid is aspirated in conjunction with the suction tube 1, connecting tube 12, and suction bend 15. At the same time, the first control valve 17 is opened, and the liquid is temporarily transported into the storage cylinder 18 through the connecting tube 16. The suction device is stored in a timely manner to facilitate its own suction setting. The limiting sleeve 34 on one side of the fixing ring 33 is moved.
