The device has simpler structure, and can realize switching between continuous liquid pumping and injection only by switching the two three-way valves in use, one user can easily complete the whole operation, and thereby the device is quite convenient in use.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, specifically, relates to a kind of continuous pump, belongs to field of medical technology.
Background technology
In clinical position, its treatment of abscess that thoracic cavity, abdominal cavity, pelvic cavity, part parenchymal viscera such as liver exist often needs tapping, flushing and injects some medicines; Often to carry out conduit experiment or cystography when suspecting rupture of bladder; Suspect that pyloric obstruction often will carry out the experiment of saline load.Clinical manipulation like that is very common in clinical position.Above clinical manipulation all needs to inject continuously to extract out or extract out continuously to diseased region to reinject tens or the hundreds of milliliters of liquid without exception.
In these operations, be very loaded down with trivial details with ordinary syringe and the operation of unidirectional puncture needle.Collecting or injecting flowing fluid ratio more after a little while, use ordinary syringe once to finish, but at the flowing fluid ratio of collecting, injecting more for a long time, often need separate syringe and be connected with the glue silicone tube, and the syringe needle that the other end connected of glue silicone tube is to be inserted on the patient's body always, so very inconvenient.Use the unidirectional puncture needle can only unidirectional continuous extraction or inject liquid, so just need two unidirectional puncture needles just can finish, and complicated operation, in case cooperate not in place between the personnel that undergo surgery, ambient atmos never presss from both sides in the glue silicone tube that closes and enters the thoracic cavity, will cause foreign body or cross infection, cause malpractice.
The utility model content
Problem to be solved in the utility model is at above problem, and a kind of continuous pump simple in structure, easy to use is provided.
For overcoming the above problems, the technical scheme that this utility model adopted is: a kind of continuous pump, it is characterized in that: described pump comprises the conduit and the syringe connection tube of connection, connection place of conduit and syringe connection tube is communicated with pipette, be communicated with drainage tube on the syringe connection tube, be communicated with bypass pipe between drainage tube and the conduit, described pump is provided with control device.
As further improvement in the technical proposal:
Described control device comprises first three-way valve that is arranged on pipette, conduit and syringe connection tube connection place, and this first three-way valve is communicated with syringe connection tube selectively or syringe connection tube is communicated with conduit with pipette.
Be provided with first check valve in the syringe connection tube between described first three-way valve and the drainage tube, the import of this first check valve is communicated with the outlet of first three-way valve.
Described control device comprises second three-way valve that is arranged on drainage tube and bypass pipe connection place, and this second three-way valve is communicated with syringe connection tube selectively or syringe connection tube is communicated with bypass pipe with drainage tube.
Be provided with second check valve in the drainage tube of described second three-way valve and syringe connection tube, the outlet of this second check valve is communicated with the import of second three-way valve.
Described conduit is communicated with puncture needle.
Described syringe connection tube is communicated with syringe.
Described pipette is communicated with injection bottle.
Described drainage tube is communicated with liquid-collecting bottle.
This utility model adopts technique scheme, have the following advantages: use two three-way valve and two check valves that conduit, syringe connection tube, pipette and drainage tube are communicated with, relatively simple for structure, during use, only two three-way valve of needs conversion just can be realized the conversion between continuous drawing liquid and the injecting fluid, a people just can easily finish whole operation, and is very easy to use.
The utility model is described in further detail below in conjunction with drawings and Examples.
