Description

Technical Field

[0001] The utility model belongs to the technical field of suction devices, and particularly relates to an electric negative pressure suction device. Background Art

[0002] In medical research or clinical trials, a suction device is often used to suck out bleeding, exudate, pus and the contents of thoracic organs during surgery. The principle is to make the suction head in a negative pressure state, so that the atmospheric pressure will squeeze the substances outside the suction head towards the suction head, thus completing the "suction" effect.

[0003] The existing electric negative pressure suction device usually sucks the extracted pus into a liquid storage bottle. However, when the liquid level inside the liquid storage bottle is too high, it is difficult to quickly remind medical staff, resulting in the liquid inside the liquid storage bottle being prone to leakage, which is likely to contaminate the device body and is not conducive to the normal use of the device. In addition, the existing device is difficult to limit liquid storage bottles of different specifications, resulting in the liquid storage bottle being easily detached from the device when the device is moved on a bumpy road section, which is likely to cause the liquid storage bottle to be damaged and is not convenient for protecting the liquid storage bottle.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] (1) By setting the liquid level alarm component in the utility model, when the liquid level in the liquid storage bottle is too high, the liquid will enter the inside of the connecting cylinder through the liquid inlet. Then, as the liquid level rises, the floating block moves upward inside the connecting cylinder, causing the floating block to drive the rod to move upward, so that one end of the rod touches the switch, and the alarm sounds through the switch to give an alarm. This realizes timely reminding of medical staff when the liquid level in the liquid storage bottle is too high, greatly reduces the probability of liquid leakage inside the liquid storage bottle, and further prevents pollution to the device body, which is beneficial to the normal use of the device.

[0013] (2) By setting the protection component in the utility model, when it is necessary to limit the liquid storage bottle, pull the connecting plate outward, so that the connecting plate drives the slider to move to one side of the sliding groove, causing the spring to be compressed inside the sliding groove. Then, place the liquid storage bottle on the placement groove, make one side of the liquid storage bottle contact the fixing block, and release the connecting plate. The connecting plate moves toward one side of the liquid storage bottle under the elastic force of the spring, so that the connecting plate and the fixing block clamp the liquid storage bottle, thus realizing the limitation of the liquid storage bottle, preventing the liquid storage bottle from easily falling off the device when the device moves on a bumpy road, and further preventing the liquid storage bottle from being damaged, which is convenient for protecting the liquid storage bottle.
