Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, in particular to an electric suction aid for biomedicine. Background Art

[0002] Biomedicine refers to the use of biotechnology to develop and produce drugs for the prevention, diagnosis and treatment of human diseases; currently, medical staff use electric suction machines to absorb biomedicine. The electric suction machine is a handheld medical device for transferring large volumes of liquids in medical laboratories. The electric suction machine mainly achieves the absorption of biomedicine by pressing the suction button to drive the motor to move the piston, and the discharge button to drive the motor to move the piston to discharge the biomedicine.

[0003] After searching, a patent document with patent announcement number CN215940016U discloses a telescopic electric suction aid, including a handle, a threaded connector and a mounting part. The top of the handle is equipped with a suction aid body, the bottom of the handle is equipped with a threaded connector, the outer side of the threaded connector is equipped with a mounting part through a thread, and the bottom of the handle is movably equipped with a first telescopic plate, the outer side of the first telescopic plate is provided with a telescopic groove, and the telescopic groove is engaged with the inner wall of the handle, and the two sides of the handle are symmetrically provided with mounting grooves. The first telescopic plate is symmetrically installed at the bottom of the handle, and the first telescopic plate can be pulled out downward when in use, and the suction aid can be fixed by a fixed suction cup. At the same time, a telescopic device is installed inside the mounting groove, and a fixed plate is installed at the bottom of the telescopic device. The telescopic device is fixed by the suction cup at the bottom of the fixed plate, so that the suction aid body is more stable.

[0004] However, it still has the following disadvantages in actual use:

[0005] 1. The existing telescopic electric suction assisting device has a single structure during use, which makes it inconvenient for medical staff to carry the pipette with the existing telescopic electric suction assisting device. Instead, the device is carried through an external storage box, which requires medical staff to carry the existing telescopic electric suction assisting device and the pipette separately with both hands, making it inconvenient for medical staff to carry other related medical equipment at the same time;

[0006] 2. During use, the existing telescopic electric suction assist device uses the provided sleeve plate, the second telescopic plate and the fixed plate to assist in supporting the handle standing on the tabletop, thereby further improving the stability of the existing telescopic electric suction assist device standing on the tabletop, thereby better aspirating biomedicine. However, it is inconvenient to limit the position of the folded sleeve plate, the second telescopic plate and the fixed plate, which may cause the sleeve plate, the second telescopic plate and the fixed plate to be accidentally unfolded, and may even affect the medical staff's control of the existing telescopic electric suction assist device to aspirate biomedicine.

[0007] To this end, we provide a biomedical electric suction aid to solve the above-mentioned problems. Utility Model Content
