Abstract

An integrated dual-cavity liquid pusher and its application method, which features that the position of a three-way valve is changed to fulfil the procedure from preparing liquid to push it, are disclosed. Its advantages are convenient operation and no pollution.

Description

The using method of integrated two-chamber liquid extruding device

Technical field

The present invention relates to a kind of using method of utensil, more particularly, the present invention relates to a kind of using method of liquid extruding device.

Background technology

Existing liquid extruding device is the duplex syringe, and the using method of this duplex syringe is, needs before this with two other tool syringes two kinds of solution are prepared, and the syringe that uses in the solution reuse process for preparation after the preparation injects the duplex syringe respectively.The such shortcoming of duplex syringe on using method is: 1, how operating procedure is and numerous and diverse, and clinical use is very inconvenient, increased the possibility of maloperation simultaneously; 2, the operating time long, need in advance above preparation half an hour; Easily pollute when 3, operating.

Summary of the invention

The present invention has overcome the deficiency on the existing duplex syringe using method, provides a kind of operating procedure in use few, be difficult for to produce maloperation, pollution-free, the operating time short, the using method of convenient and safe integrated two-chamber liquid extruding device.

The present invention realizes by following proposal, and the three-way valve 3 of integrated two-chamber liquid extruding device from home position Fig. 3, is rotated into Fig. 4 position; Lysate in the syringe 1 or diluent are pushed in the container 4 that content is housed; Shake integrated two-chamber liquid extruding device, fully the content in dissolving or the cut-back tank; In the solution suction syringe 1 after dissolving in container 4 or the dilution; 3 one-tenth user mode Fig. 5 of swivel tee valve position; Solution or diluent are released;

Compare with the using method of existing duplex syringe, the invention has the beneficial effects as follows: it does not make various steps such as lysate, content, syringe, course of dissolution, powder charge process organically combine when no longer being to use duplex syringe method, makes operation from dilution or be dissolved into and push away each step of liquid and all separate respectively and carry out.The present invention realizes corresponding step by the diverse location of regulating spool.The lysate owing to when producing or use, in two syringes, packed into, having packed in two containers needs dilution or dissolved content, according to the diverse location of operation sequence conversion spool, the present invention just can realize from dilution or be dissolved into the overall process that pushes away liquid during use.

Description of drawings

Fig. 2 is plain triple valve valve core structure figure;

Fig. 3 is integrated two-chamber liquid extruding device original state, and be step 1 this moment, and spool position as shown in the figure;

Fig. 4 is an integrated two-chamber liquid extruding device step 2 when using, and is the dosing state, and spool position as shown in the figure;

Fig. 5 is an integrated two-chamber liquid extruding device step 3 when using, and is user mode, and spool position as shown in the figure;

The specific embodiment

Below in conjunction with accompanying drawing the present invention is described in further detail: among the described embodiment of Fig. 1, integrated two-chamber liquid extruding device is by syringe 1 and fixed support 2 that two syringes are coupled together, one end has the container 4 of removable seal member, support 5 is fixing with container 4 with two syringes 1, and two isolating three-way valve 3 constitute, wherein first port of three-way valve links to each other with a syringe conehead, and second port links to each other with a container, and the 3rd port links to each other with ejecting device.

During use with the spool of three-way valve from home position Fig. 3, be rotated into dosing state diagram 4 positions, at this moment syringe communicates with container but does not communicate with shower nozzle, lysate in the syringe is pushed in the container, after content or lysate fully dissolved in container or dilute, solution or diluent suction syringe, rotary spool became user mode Fig. 5 position, this position makes syringe communicate with shower nozzle but does not communicate with container, and solution or diluent release are got final product.

Claims

1, the using method of integrated two-chamber liquid extruding device is characterized in that:

1.1 three-way valve (3) from the home position (Fig. 3), is rotated into (Fig. 4) position;

1.2 lysate in the syringe (1) or diluent are pushed in the container (4) that content is housed;

1.3 shake integrated two-chamber liquid extruding device, fully the content in dissolving or the cut-back tank (4);

1.4 in the solution suction syringe (1) in container (4);

1.5 swivel tee valve (3) becomes user mode (Fig. 5) position;

1.6 solution or diluent are released.
