This device can be automatic continuous clear away the waste liquid in the test tube, improves experimental efficiency greatly.
Description
Technical Field
The utility model relates to medical examination equipment, in particular to a device capable of continuously absorbing liquid.
Background
At present, in a plurality of medical tests and gene detection, waste liquid in a batch of small-sized pointed-bottom test tubes needs to be removed. At present, two modes are generally adopted in a laboratory, firstly, an experimenter directly holds test tubes and pours waste liquid into a waste liquid pool one by one, and the other method is to use a manual liquid-moving gun to suck the waste liquid in the test tubes and then discharge the waste liquid into the waste liquid pool, and the operation is carried out in a reciprocating mode. Therefore, the existing waste liquid discharge mode wastes time and labor, the labor intensity of operators is increased, and the experiment efficiency is greatly reduced.
Disclosure of Invention
Aiming at the defects in the prior art, the utility model provides a continuous liquid suction device which can automatically and continuously remove waste liquid in a test tube.
In order to realize the purpose, the adopted technical scheme is as follows:
the utility model provides a continuous imbibition device, includes the pump body and imbibition rifle, the imbibition rifle is including the rifle body that is used for gripping, the front end of the rifle body is equipped with the rifle mouth, and the rear end of the rifle body is equipped with the joint, the rifle mouth passes through the inside vertical passageway that link up of the rifle body and connects the intercommunication, the import of the pump body passes through the joint connection of pipeline and rifle body rear end, the export installation drain pipe of the pump body.
Furthermore, the side of the gun body is provided with a button switch for controlling the pump body to start and stop and a knob switch for controlling the flow rate of the pump body.
Furthermore, a filter device is arranged on a drain pipe at the outlet of the pump body.
Further, the pump body is a liquid-gas dual-purpose pump.
Furthermore, a gun head retreating sleeve is arranged on the gun body, the gun head retreating sleeve can move up and down along the gun body, a return spring is arranged between the gun body and the gun head retreating sleeve, and a pressing part is formed at the rear end of the gun head retreating sleeve.
When the device is used, the gun head can be arranged on the gun nozzle, and the drain pipe is placed into the waste liquid pool. The experimenter holds the gun body with one hand and presses the button switch, and the pump body starts to work. Stretch into the rifle head in the upper waste liquid of target test tube, the waste liquid on test tube upper strata is absorb by the pump body, enters into the internal portion of rifle through rifle head and rifle mouth in proper order, then discharges by its rear end through the passageway of the internal portion of rifle, enters into the pump body through the pipeline. The waste liquid filters the back through the filter equipment of drain pipe and discharges into the waste liquid pond, and experiment operating personnel can carry out the waste liquid operation of arranging of next test tube at once. Therefore, compared with the conventional mode of sucking and discharging or manually pouring liquid, the device realizes the continuous and automatic waste liquid sucking function, greatly improves the experimental efficiency and reduces the labor intensity of operators.
Drawings
In order to more clearly illustrate the detailed description of the utility model or the technical solutions in the prior art, the drawings that are needed in the detailed description of the utility model or the prior art will be briefly described below. Throughout the drawings, like elements or portions are generally identified by like reference numerals. In the drawings, elements or portions are not necessarily drawn to scale.
FIG. 1 is a schematic diagram of the structure of the device;
fig. 2 is a structural view of the liquid suction gun of the utility model.
Detailed Description
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby.
The continuous pipetting device shown in fig. 1 and 2 comprises a pump body 1 and a pipetting gun 2. The pump body 1 adopts a miniature small-size liquid-gas dual-purpose pump, has the functions of a liquid pump and a vacuum pump, and ensures the stability of liquid suction.
The liquid suction gun 2 comprises a gun body 3 used for holding, a gun nozzle 4 is arranged at the front end of the gun body, and a gun head can be installed at the front end of the gun nozzle 4.
The rear end of the gun body 3 is provided with a joint 5, the gun nozzle 4 is communicated with the joint 5 through a channel which is vertically communicated with the inside of the gun body, an inlet of the pump body 1 is connected with the joint at the rear end of the gun body through a pipeline, a water outlet pipe is installed at an outlet of the pump body 1, and a filtering device 6 is installed on the water outlet pipe at the outlet of the pump body.
The side of the gun body 3 is provided with a button switch 7 for controlling the pump body to start and stop and a knob switch 8 for controlling the flow rate of the pump body. In this embodiment, the button switch 7 and the knob switch 8 are designed as an integral body, the button switch is a middle circular button, and a circular ring rotatable around the circular button constitutes the knob switch. Therefore, the starting, the stopping and the flow rate control of the pump body can be conveniently finished by an operator with one hand.
The gun body 3 is provided with a gun head retreating sleeve 9, the gun head retreating sleeve 9 can move up and down along the gun body, a return spring is arranged between the gun body and the gun head retreating sleeve, and a pressing part 10 is formed at the rear end of the gun head retreating sleeve 9. When the gun head is used, an operator holds the gun body, presses the pressing part at the rear end of the gun head retreating sleeve with a thumb to drive the gun head retreating sleeve to move downwards, and the front end of the gun head retreating sleeve pushes the gun head on the gun nozzle away.
Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; these modifications and substitutions do not cause the essence of the corresponding technical solution to depart from the scope of the technical solution of the embodiments of the present invention, and are intended to be covered by the claims and the specification of the present invention.
