Description

A drug-injectable infusion set

technical field

The utility model relates to a medical infusion device, in particular to a drug-injectable infusion set.

Background technique

The infusion set is a necessary medical material for clinical infusion. It is widely used in clinical practice and has a wide variety. Screw-in pinless connection, etc. Nowadays, with the diversification of intravenous treatment methods, Murphy's dropper injection is a commonly used method of administration in clinic. The rubber cap on the Murphy dropper of the clinically used infusion set cannot be opened. If you need to inject medicine from the Murphy dropper, you usually use a syringe to draw the medicine directly, then sterilize the Murphy dropper and insert the needle tip into the rubber. Slowly injecting medicine into the plug is not only inconvenient to operate but also likely to cause needle-stick injury during clinical use, which leads to the danger of occupational exposure and may also cause infusion reactions due to irregular disinfection. According to the requirements of the 2011 INS Guidelines and the 2014 Intravenous Therapy Nursing Technical Operation Specification, it is imperative to implement needle-free infusion and avoid needle-stick injuries among medical staff.

Utility model content

The purpose of the utility model is to solve the problems existing in the prior art, and to provide a new drug-injectable infusion set with simple structure, convenient use, non-pollution, and practicality.

The purpose of this utility model is achieved through the following technical solutions:

An injectable infusion set, comprising a Murphy-type dropper; above the Murphy-type dropper, a dosing tube matching the syringe mastoid is arranged; there is a layer of filter membrane inside the dosing tube, and a dosing tube outside the dosing tube External thread; the dosing tube is closed by a twistable cap with internal thread. The filter membrane in the dosing tube can effectively prevent the liquid medicine injected into the Murphy dropper from being polluted, and the twistable cap is easy to open and securely close the Murphy dropper.

The material of the injectable infusion set is preferably non-PVC or TPE material.

Preferably, the dosing tube is 10mm high, the filter membrane is 2mm below the dosing tube, the inner diameter above the filter membrane is 5mm, the inner diameter below the filter membrane is slightly less than 5mm (to fix the filter membrane), and the outer diameter is 7mm; The cap is 7mm high, with an inner diameter of 7mm and an outer diameter of 9mm.

The utility model is suitable for various types of syringes, has tight connection, is simple and convenient to use, and reduces the occurrence probability of needle stick injuries. Unscrew the cap when dosing, inject the syringe with the mastoid and the dosing tube, and tighten the cap after the injection is completed. After the drug is injected, the number of drops is still adjusted by the regulator.

The utility model is for one-time use, can be replaced once within 24 hours, and can be injected multiple times within 24 hours.

The beneficial effects of the utility model are:

(1) The utility model is simple and practical, convenient for medical staff to operate, and reduces the hazards of needle stick injuries and occupational exposure.

(2) The utility model can inject medicine multiple times within 24 hours, and after injecting the medicine, still adjust the number of drops through the regulator.

(3) The utility model is closely connected with the syringe mastoid, and the injected medicinal solution is filtered through the filter membrane, which can effectively prevent pollution.

(4) The utility model has a simple structure and low price, and can be widely used in clinical practice. Due to the large market demand, it is possible to replace traditional devices, so it has great market prospects.
