Embodiment 1

[0043] like figure 1 and figure 2 As shown, the present embodiment provides a manual aspirator, comprising:

[0044] A suction tube 1, one end of the suction tube 1 is formed with a suction end for sucking the substance to be sucked;

[0045]Wherein the suction tube 1 can extend into the patient's chest cavity, abdominal cavity, and airway so that its suction end can be close to or directly contact with materials such as sputum, pus, and blood to be sucked out.

[0046] A transfer chamber 2, the transfer chamber 2 is internally formed with an accommodating space for accommodating the substance to be sucked, and the accommodating space communicates with the end opposite to the suction end of the suction tube 1;

[0047] The transfer chamber 2 plays the role of storage and transfer, and is used for temporarily storing liquid and connecting the negative pressure device 5 . Since the transfer chamber 2 is in communication with one end of the suction tube 1, the substance to be...

Embodiment 2

[0065] like Figure 4 As shown, this implementation is further improved on the basis of Embodiment 1. In this embodiment, the manual aspirator includes at least two negative pressure devices 5 that are connected to each other to provide negative pressure for the manual aspirator.

[0066] When the aspirator of the embodiment is in use, the medical staff squeezes one of the negative pressure devices 5 and then releases it, so that the negative pressure device 5 generates a negative pressure environment. During the suction process of the aspirator, due to the air pressure at the suction end, the negative pressure value of the negative pressure device 5 will gradually decrease and tend to zero. At this time, before the negative pressure value of the negative pressure device 5 is reduced to a certain set threshold value, squeeze the remaining certain negative pressure device 5 and release it to replace the previous negative pressure device 5 to provide suction for the suction dev...

Embodiment 3

[0068] like Figure 5 As shown, the manual aspirator in this embodiment also includes a storage chamber 6 connected to the transfer chamber 2 , and the storage chamber 6 is used to receive the aspirated substance sucked into the transfer chamber 2 . Since the absorbed substance entering the transfer chamber 2 through the suction tube 1 exceeds a certain amount, the work of the aspirator will be affected, so it is necessary to transfer the absorbed substance in the transfer chamber 2 from the transfer chamber 2 in time. However, in this embodiment, a storage chamber 6 connected to the transfer chamber 2 is provided to receive the absorbed substance transferred from the transfer chamber 2 . The storage chamber 6 can be connected to the transfer chamber 2 in a detachable manner. When there are too many absorbed substances in the storage chamber 6, the storage chamber 6 is disassembled, and the absorbed substances in the storage chamber 6 are removed before being connected to the ...

Abstract

The invention provides a manual aspirator and a manual sucking method, relates to the technical field of medical apparatus, and is used for performing liquid sucking on a patient. The manual aspiratorcomprises a suction catheter, a transferring chamber and one or more negative pressure devices, wherein each negative pressure device comprises an internal space of which the volume is changeable, and is used for producing positive pressure environment and negative pressure environment, and a first switching device and a second switching device. The manual sucking method comprises the following steps of S1, exerting extruding effect to the negative pressure devices; S2, exhausting gas in the internal space to the outside atmospheric environment; S3, removing the extruding effect exerted on the negative pressure devices; and S4, sucking materials to be sucked into the transferring chamber by the suction catheter through negative pressure. Through the adoption of the manual aspirator and the manual sucking method disclosed by the invention, the problem that in conventional sucking technologies, under the situation that no stable electric power supply exists, operation of sucking cannotbe quickly and effectively performed can be solved.

Description

technical field [0001] The invention belongs to the technical field of medical appliances, in particular to a manual suction device and a manual suction method. Background technique [0002] At present, when medical personnel perform fluid suction operations such as sputum suction, pus suction, and blood suction on the patient's chest cavity, abdominal cavity, and airway, they usually use electric energy to drive a vacuum pump to form a negative pressure to achieve the suction operation. Its shortcoming is: in the process of unexpected power failure, field rescue or transfer of patients, the situation that the power supply cannot be guaranteed often occurs. At this time, the electric-driven equipment cannot perform suction operations such as sputum suction and pus suction for the patient, and the patient cannot receive timely and effective treatment. Contents of the invention [0003] In view of this, the present invention provides a manual suction device to solve the tec...
