Description

Aseptic quantitative liquid abandoning device

Technical Field

The utility model relates to the field of medical equipment, especially relate to an aseptic ration abandons liquid ware.

Background

When the medical liquid infusion bottle is clinically used for treating diseases, medical staff often infuse liquid with different volumes to patients, particularly for old or infant patients, the individualized difference of the infused liquid volume is large, and the medical staff needs to discard the liquid from the infusion bottle according to the individualized infused liquid volume before infusing the liquid to the patients.

At present, medical care personnel all adopt general syringe to abandon liquid with the syringe needle, to abandoning liquid volume great time, adopt general syringe to need draw many times, just can reach suitable liquid volume of abandoning. Therefore, the needle of the syringe needs to repeatedly puncture the opening of the infusion bottle for many times, so that the sterility can not be kept, and the repeated puncture of the liquid opening can cause liquid leakage.

It is therefore apparent that the above-mentioned conventional methods for discarding syringe solutions still have the disadvantages and drawbacks, and further improvements are desired. How to create a new sterile quantitative liquid abandoning device, which can realize the repeated extraction after one-time puncture, avoid the problems of liquid leakage and pollution caused by repeatedly puncturing the opening of an infusion bottle, has simple and convenient operation, high efficiency and reduced labor intensity, and becomes the target of great improvement in the industry at present.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to provide a liquid ware is abandoned to aseptic ration, makes it realize once extracting many times after the puncture, avoids puncturing infusion bottle opening part repeatedly and the weeping and the pollution problem that leads to, and is easy and simple to handle, efficient, reduces intensity of labour to overcome the not enough of the liquid method is abandoned to current syringe.

In order to solve the technical problem, the utility model provides a liquid ware is abandoned to aseptic ration, including the syringe, malleation joint and the puncture needle that connect gradually, the malleation connects including taking the joint body that the ration holds the chamber, the one end that connects the body be equipped with the malleation piece that the nipple of syringe is connected, the other end be equipped with the end-to-end connection's of puncture needle internal thread structure, just the periphery that connects the body is equipped with at least one slice handle.

In a further improvement, the quantitative cavities of the connector body have different specifications.

In a further improvement, the specification of the quantitative cavity of the joint body is 1ml, 2ml, 5ml or 10 ml.

In a further improvement, the volume values of different specifications of the quantitative containing cavity of the connector body comprise the internal volume value of the puncture needle matched with the volume value.

In a further improvement, the periphery of the joint body is provided with two oppositely arranged sheet-shaped handles.

After adopting such design, the utility model discloses following advantage has at least:

1. the utility model discloses aseptic quantitative liquid abandoning ware connects through the malleation that sets up the area ration appearance chamber, can easily realize the ration of the inside liquid of malleation joint to through the setting of just casting die, make its cooperation quantitative syringe use, can realize once extracting the quantitative calculation of liquid medicine, can also realize the change of syringe many times, do not influence the puncture needle and the puncture hole of infusion bottle opening part, avoid the infusion bottle weeping and reduce the contaminated risk of liquid medicine.

2. Still through the setting that connects body periphery slice handle, the medical personnel of being convenient for connect the nipple of syringe for the malleation many times and carry out the plug operation, reduce the hand damage to medical personnel, reduce fatigue, lifting efficiency.

3. Still hold the chamber volume value through the ration that will connect the body and set up to the inside volume value that contains rather than the puncture needle head that matches, the liquid measure is abandoned in the accurate calculation of medical personnel of being more convenient for, provides favourable guarantee for the accurate liquid medicine of patient infusion.

Drawings

The foregoing is only an overview of the technical solutions of the present invention, and in order to make the technical means of the present invention more clear, the present invention will be further described in detail with reference to the accompanying drawings and the detailed description.

Fig. 1 is a schematic structural diagram of the aseptic quantitative liquid-discarding device of the present invention.

Detailed Description

Referring to the attached figure 1, the sterile quantitative liquid abandoning device of the utility model comprises an injector 1, a positive pressure joint 2 and a puncture needle head 3 which are connected in sequence.

The positive pressure connector 2 comprises a connector body with a quantitative containing cavity 21, a positive pressure piece 22 connected with a nipple of the injector 1 is arranged at one end of the connector body, and an internal thread structure 23 connected with the tail end of the puncture needle head 3 is arranged at the other end of the connector body. The internal thread structure 23 can ensure the sealing connection between the puncture needle head 3 and the positive pressure joint 2, and the positive pressure piece 22 can ensure the positive pressure sealing of the inner cavity of the positive pressure joint 2.

The dosing cavity 21 of the connector body has different specifications, such as 1ml, 2ml, 5ml or 10 ml. Compared with the existing positive pressure joint, the improved positive pressure joint has the advantages that the volume is greatly increased, the disposable waste liquid volume is enlarged, and the waste liquid extraction times are reduced.

In a preferred embodiment, the volume values of different specifications of the dosing cavity 21 of the connector body comprise the internal volume value of the puncture needle 2 matched with the same. The volume value of the inner part of the puncture needle head 2 is calculated in the liquid-discarding volume, so that the calculation of the liquid-discarding volume is more accurate, the calculation of medical staff is very convenient, the operation simplicity of the medical staff is greatly improved, and the beneficial guarantee is provided for the patient to infuse the accurate liquid medicine. If 50ml of liquid is required to be discarded from a 200ml infusion bottle, when a 5ml positive pressure connector and a 10ml syringe are adopted, the puncture needle 3 is inserted into the infusion bottle only after the puncture needle 3, the positive pressure connector 2 and the syringe 1 are connected, 10ml of liquid is extracted from the syringe 1 for the first four times, and the needle 3 is pulled out after 5ml of liquid is extracted for the fifth time, so that 50ml of liquid can be accurately discarded.

In addition, in this embodiment the periphery that connects the body is equipped with two relative settings slice handle 24, medical personnel of being convenient for grasp when connecting malleation joint 2 and puncture needle 3 or syringe 1, reduce medical personnel hand fatigue and damage, reduce intensity of labour, raise the efficiency.

The aseptic quantitative liquid-discarding device of the utility model can avoid the repeated insertion and extraction of the puncture needle head to the opening of the infusion bottle, avoid the leakage of the infusion bottle and reduce the risk of the contamination of the liquid medicine by adding the positive pressure joint between the puncture needle head and the injector; still hold the chamber volume through the inside that increases the malleation and connect to carry out the ration to it, can not only reduce and abandon liquid extraction number of times, can also easily realize abandoning the accurate calculation of liquid measure, bring very big facility for medical personnel's operation. Still connect the setting of periphery slice handle through the malleation, the operation of being convenient for, and reduce fatigue and the damage to medical personnel's hand, do benefit to the hospital and use widely.
