Abstract
The utility model discloses an improved rubber pipette bulb, which comprises a rubber pipette bulb main body, one-way ventilation flaps, an upper port and a lower port. Two one-way ventilation flaps are arranged in the rubber pipette bulb which is provided with the upper port and the lower port, and gas enters the rubber pipette bulb from the lower port through the one-way motion of the flaps and is discharged from the upper port, so that the rubber pipette bulb continuously drives liquid to rise.
Description
Affiliated technical field
The utility model relates to a kind of rubber pipette bulb that two ports are arranged.
Background technology
Present rubber pipette bulb all is by a port input and output gas; In the laboratory, use imbitition with the pipette combination; When liquid does not reach corresponding height and rubber pipette bulb has restored to the original state, need both separation be pushed rubber pipette bulb again with imbitition, cause operational inconvenience.
Summary of the invention
The purpose of the utility model provides and a kind ofly need not to separate with pipette and the rubber pipette bulb of imbitition continuously.
The utility model solves the technical scheme that its technical problem adopted: a kind of Improvement type rubber pipette bulb comprises the rubber pipette bulb main body, unidirectional air ventilation membrane lobe, port, lower port; It is characterized in that: two unidirectional air ventilation membrane lobes are placed in the rubber pipette bulb with two ports up and down, the one-way movement through valve can make gas got into by the lower port of rubber pipette bulb, discharges from the port of rubber pipette bulb.
The beneficial effect of the utility model is when rubber pipette bulb is not drawn the liquid of enough height for the first time, can continue to push imbitition, and need not to separate with pipette again.
Description of drawings
Below in conjunction with accompanying drawing the utility model is done further explain.
Accompanying drawing is the structure principle chart of the utility model.
Drawing explanation: 1. unidirectional air ventilation membrane lobe, 2. unidirectional air ventilation membrane lobe, 3. rubber pipette bulb main body, 4. port, 5. lower port.
The specific embodiment
The Improvement type rubber pipette bulb comprises rubber pipette bulb main body (3), unidirectional air ventilation membrane lobe (1) (2), port (4), lower port (5).
Unidirectional air ventilation membrane lobe (1) is placed in the port (4) of rubber pipette bulb main body (3), unidirectional air ventilation membrane lobe (2) is placed in the lower port (5) of rubber pipette bulb main body (3).During extruding rubber pipette bulb main body (3), unidirectional air ventilation membrane lobe (2) closure, unidirectional air ventilation membrane lobe (1) is opened discharge gas; When unclamping rubber pipette bulb main body (3), unidirectional air ventilation membrane lobe (1) closure, unidirectional air ventilation membrane lobe (2) is opened and is sucked gas to drive the liquid rising in the pipette, and this process repetitive operation just can be drawn enough liquid.
Claims (1)
1. an Improvement type rubber pipette bulb comprises the rubber pipette bulb main body, unidirectional air ventilation membrane lobe, port, lower port; It is characterized in that: two unidirectional air ventilation membrane lobes are placed in the rubber pipette bulb with two ports up and down, the one-way movement through valve can make gas got into by the lower port of rubber pipette bulb, discharges from the port of rubber pipette bulb.
