Description

Sterile solvent dissolver

Technical field

The utility model belongs to the technical field of medical instruments and relates to a sterile drug dissolver.

Background technique

Clinically, when the patient is treated with large infusion, the traditional dispensing process is: the medical staff takes out the drug ampule, disinfects the ampoule bottleneck and the large-capacity injection butyl rubber stopper with alcohol, cuts the bottleneck of the ampoule with a grinding wheel, and smashes it by hand. Or directly break the bottleneck, use a syringe to aspirate the drug once and then inject it into a large-capacity injection bottle. The disadvantages of this traditional transfer liquid are: it does not meet the clinical use specifications of the drug; there are many operating procedures, and the probability of error increases; it is easy to cause waste of the liquid or finger injury when opening or breaking the ampoule, and the broken glass may also be for the patient. Brings unnecessary harm; the liquid is in contact with the air, which is likely to cause secondary pollution. For some drugs with strong toxicity, it can have a greater impact on the environment and pose a greater hazard to the health of medical personnel.

At present, there are also some automatic dosing devices, which adopt the whole installation of the vial and the needle sleeve and the medicine bottle sleeve filled with the compressed inert gas. Due to the unreasonable structure of the fixing pin, the demoulding is difficult to produce during production. Production and production costs are high, and the reliability of the product in actual use is poor.

technical problem

The purpose of the utility model is to provide a sterile solvent dissolving device, which solves the problem that the prior art has unreasonable structure due to the fixing manner of the conductive pin, which makes the demoulding difficult in production and production, high in production and production cost, and reliable in actual use. Poor sex.

Technical solution

The technical solution adopted by the utility model is a sterile solvent dissolving device, comprising a casing, one end of the outer casing is connected with the lower seat of the outer casing, and the bottom end of the lower seat of the outer casing is provided with a cover, and the outer casing of the lower casing is connected with a connection. a seat, a spring is mounted between the lower seat of the outer casing and the connecting seat; the shaft of the connecting seat is fixedly mounted with a needle seat, and a double-edged needle tube is installed in the needle seat;

A button is mounted in the through hole at the other end of the outer casing, and a needle of one end of the double-blade needle passes through the button, and a shaft is mounted on the shaft of the button, and the cap is placed on the needle at one end of the double-edged needle through the button.

Beneficial effect

The utility model has the beneficial effects that the powder bottle is filled with a solvent in the clinic, and the dissolved liquid is transferred through a double-edged needle tube by using the pressure in the medicine bottle; the sterile drug dissolver belongs to a one-time use The use of the article is only applicable to clinically sterile dissolved and transferred liquids and should not be used for human injection.

Embodiments of the invention

The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

As shown in FIG. 1 , FIG. 2 and FIG. 3 , the structure of the sterile drug dissolver of the present invention comprises a casing 5 , one end of the casing 5 (the bottom end of the illustration, that is, the lower end of the product where the product is normally placed) and the casing. The lower seat 8 is screwed, and the bottom end of the lower housing 8 is provided with a cover 9 in which the connecting seat 6 is mounted in the annular interlayer, and a spring 7 is mounted between the lower housing 8 and the connecting seat 6; The shaft of the 6 is fixedly mounted with a needle seat 4, and the double seated needle tube 2 is mounted in the needle seat 4;

A button 3 is mounted in the through hole of the other end (the upper end in the drawing) of the outer casing 5, and the needle of one end of the double-edged needle tube 2 passes through the button 3, and the shaft of the button 3 is mounted with a cap 1 which is covered by the cap 1 One end of the double-edged needle 2 of the button 3 is on the needle.

The inner end of the button 3 (the lower end in the drawing) is provided with an outward elastic hook, and the inner surface of the outer casing 5 is provided with a step, and the hook of the button 3 can be hooked on the inner surface step of the outer casing 5, and the button 3 is depressed. The connecting seat 6 and the hub 4 thereof are pushed up, so that the double-edged needle tube 2 in the needle seat 4 is pushed downward, and the hook of the button 3 can be hooked firmly against the step for the mixing operation.

The working principle of the drug dissolver of the utility model is:

The solvent dissolver is used to ingeniously connect a solvent bottle and an injectable powder vial, and the solvent bottle is filled with a gas that meets the requirements of the pharmaceutical and generates the required pressure. When in use, the solvent dissolves the two, and the solvent in the solvent bottle enters the powder injection bottle under pressure. After the powder is fully dissolved, the residual pressure in the bottle is introduced into the large infusion bottle to carry out the aseptic transfer of the liquid.

The method for using the drug dissolver of the present invention is as follows: Referring to FIG. 4 and FIG. 5,

1. Check if the bag is in good condition.

2. Disinfect the injection zone of the solvent bottle and the powder bottle with 75% alcohol.

3. Open the outer package, remove the cover 9, and insert the bottle needle into the lower seat of the dissolver housing.

4. Press the button 3 down, so that the lower end of the double-edged needle tube 2 pierces the powder needle bottle, remove the protective cap 1, invert the solvent bottle, and press it down, so that the upper end of the double-edged needle tube 2 pierces the rubber bottle stopper of the solvent bottle. The liquid in the solvent bottle is completely inserted into the powder bottle through the double-blade needle 2.

5. Press down on the bottom of the solvent bottle. At this time, the double-edged needle tube 2 is withdrawn from the lower powder bottle, and the solvent bottle is removed and discarded.

6. Install the protective cap 1 and shake the powder needle bottle to dissolve the liquid.

7. Unplug the cap 1 and insert the powder bottle with the drug dissolver vertically into the bottle of the large infusion bottle (or soft bag infusion bottle), and press down on the vial to pierce the double-edged needle 2 again. The rubber plug is used to introduce the liquid into a large infusion bottle (or a soft bag infusion bottle).

8. After the transfer is completed, remove the solvent dissolver, put on the protective cap 1, and cover 9 for centralized treatment.
