Description

Device for preparing powder and liquid

Technical Field

The utility model belongs to the technical field of nursing auxiliary instrument, concretely relates to a device that is used for powder and liquid to prepare.

Background

In clinical work, the prepared liquid accounts for a large part of the workload, most of the prepared powder is prepared into the liquid, so that the injector is required to perform plugging and unplugging operations on the medicine bottle stopper for at least 2 times, and the workload is large; the needle stick injury of the nursing personnel is easily caused in the repeated plugging process, and the injury is brought to the nursing personnel; when the syringe is repeatedly inserted and pulled, the content of the syringe needle is easily blocked by particles of a rubber plug in the bottle stopper, so that infusion particles are easily caused, and harm is brought to patients and nursing; the liquid medicine is easy to splash in the process of sucking the liquid medicine, so that the concentration of the liquid medicine does not reach the standard and the curative effect is affected.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a device that is used for powder and liquid to prepare to solve above-mentioned problem.

In order to achieve the above object, the utility model discloses a technical scheme be:

the utility model provides a device for powder and liquid are prepared, includes pipeline I and pipeline II, the both ends of pipeline I and pipeline II set up the syringe needle respectively and are used for being connected with liquid bottle and powder bottle, set up needle tubing I and needle tubing II on pipeline I and the pipeline II respectively, set up the three-way pipe between needle tubing I and the pipeline I respectively and between needle tubing II and the pipeline II, set up the check valve on pipeline I and the pipeline II of three-way pipe both sides respectively.

In order to further realize the utility model, the needle tube I and the needle tube II are respectively arranged at 1/2 positions of the lengths of the pipeline I and the pipeline II.

In order to further realize the utility model discloses, the open direction of check valve all faces the powder bottle on pipeline I, and the open direction of check valve all faces the liquid bottle on pipeline II.

The utility model discloses compare in prior art's beneficial effect do:

the utility model discloses a pipeline I and pipeline II communicate with liquid bottle and powder bottle respectively, suction through needle tubing I makes its and the check valve between the liquid bottle open, inhale liquid in needle tubing I, the propelling movement of rethread needle tubing I is opened its and the check valve between the powder bottle, carry out powder liquid fusion and obtain the liquid medicine in pushing into the powder bottle with liquid, then make its and the check valve between the powder bottle open through II suctions of needle tubing, inhale liquid medicine in needle tubing II, the propelling movement of rethread needle tubing II is opened its and the check valve between the liquid bottle, push into the liquid bottle with the liquid medicine, through the circulation of relapseing a lot of, finally with the powder in the powder bottle and the liquid misce in the liquid bottle.

The utility model discloses can effectively reduce the production of infusion particle, reduce the negative pressure splash, need not to relapse the plug syringe needle on powder bottle and liquid bottle, carry out the fluid mixing, only take out several times through two needle tubes and put and can accomplish the mixed configuration of powder and liquid, reduce nursing staff's intensity of labour, operation simple accurate, save time.

Drawings

Fig. 1 is a schematic structural view of the present invention;

the reference numerals have the following meanings: 1. a pipeline I; 2. a pipeline II; 3. a needle head; 4. a liquid bottle; 5. powder bottles; 6. a needle tube I; 7. a needle tube II; 8. a three-way pipe; 9. a one-way valve; 10. a one-way valve I; 11. a one-way valve II; 12. a one-way valve III; 13. and a one-way valve IV.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and the following detailed description.

As shown in figure 1, a device for preparing powder and liquid comprises a pipeline I1 and a pipeline II 2, wherein two ends of the pipeline I1 and the pipeline II 2 are respectively provided with a needle 3 for being connected with a liquid bottle 4 and a powder bottle 5, the pipeline I1 and the pipeline II 2 are respectively provided with a needle tube I6 and a needle tube II 7, a three-way pipe 8 is respectively arranged between the needle tube I6 and the pipeline I1 and between the needle tube II 7 and the pipeline II 2, and the pipeline I1 and the pipeline II 2 on two sides of the three-way pipe 8 are respectively provided with a one-way valve 9.

And the needle tube I6 and the needle tube II 7 are respectively arranged at 1/2 positions of the lengths of the pipeline I1 and the pipeline II 2.

The opening direction of check valve 9 all faces powder bottle 5 on pipeline I1, and the opening direction of check valve 9 all faces liquid bottle 4 on pipeline II 2.

Before configuration, the needles 3 at the two ends of the pipeline I1 and the pipeline II 2 are respectively inserted into the powder bottle 5 and the liquid bottle 4.

When the configuration operation is carried out, firstly, a piston rod of a needle tube I6 is pulled, so that a one-way valve I10 between the needle tube I6 and a liquid bottle 4 is opened, liquid enters the needle tube I6 through the one-way valve I10, at the moment, a one-way valve II 11 between the needle tube I and a powder bottle 5 is in a closed state, one-way valves 9 on a pipeline II 2 are in a closed state, then the piston rod of the needle tube I6 is pushed, the liquid is pushed out, the one-way valve I10 is closed, the one-way valve II 11 is opened, the liquid enters the powder bottle 5 and is mixed with powder to form mixed liquid medicine, and at the moment, 2 one-; and pulling a piston rod of the needle tube II 7 to open a check valve III 12 between the needle tube II 7 and the powder bottle 5, enabling the mixed liquid medicine to enter the needle tube II 7 through the check valve III 12, enabling the other three check valves 9 to be in a closed state, then pushing the piston rod of the needle tube II 7, pushing out the mixed liquid medicine, closing the check valve III 12, opening a check valve IV 13, enabling the mixed liquid medicine to enter the liquid bottle 4 to be mixed with liquid to form secondary mixed liquid medicine, and enabling the liquid circulation direction to be shown by an arrow in the attached drawing 1. Repeating the above operation for multiple times to complete the uniform mixing of the powder and the liquid, and pulling out the needle 3 after the mixed liquid medicine is pushed into the liquid bottle for the last time and the configuration is finished.
