Problems solved by technology

[0004] Although the above-mentioned invention can realize the automatic sealing of the infusion pipeline, when the infusion starts, the pressure in the infusion tube below the buoyant body is greatly reduced because the buoyancy of the floating body hinders the downward flow of the medicinal liquid when the infusion is started. During the pipeline, the amount of liquid medicine remaining in the infusion tube is very small, which also causes the pressure in the infusion tube to drop greatly. It will often flow back into the infusion tube, or even back into the medicine bottle, causing blood coagulation in the infusion tube or medicine bottle, which may endanger the life of the patient
At the same time, its structure is more complicated, and its production cost is also higher.

Embodiment 1

[0019] Such as Figure 1 to Figure 5 , a disposable self-closing safety infusion set of the present invention, comprising a bottle insertion needle 1, an infusion hose 2, a drip tube 3, and an infusion needle 6 connected sequentially, wherein a vent tube 8 is connected below the bottle insertion needle 1, A medicine feeding tube 7 is connected above the drip tube 3, and a flow regulator 5 for controlling the liquid flow is placed outside the infusion hose, and at least There is a safety self-closing component 4 , and the safety self-closing component 4 includes an airtight membrane body 41 , a guiding liquid 42 and a containing liquid 43 . The liquid container 43 is a component that holds the liquid medicine, and can have different shapes, not limited to a cylindrical shape, as long as it can hold the liquid medicine; the liquid container 43 is provided with at least one liquid medicine outlet 431, In this embodiment, the liquid medicine outlet 431 is disposed at the bottom o...

Embodiment 2

[0023] The structure of this embodiment is basically the same as that of the above embodiment, the only difference is that the liquid container 43 and the dropper 3 in this embodiment are separated, and the same structure will not be described in detail. Such as Figure 7 As shown, after the container liquid 43 of the safety self-closing assembly 4 is set separately from the drip tube 3, the infusion hose 2 can be used to connect therebetween. Using this embodiment can also effectively achieve the purpose of safe transfusion.

Embodiment 3

[0025] The structure of this embodiment is basically the same as that of the above embodiment, the only difference is that the material composition of different parts of the airtight film body 41 in this embodiment is different, but at least the opening on the side of the airtight guide liquid is made of elastic material, Its identical structure will not be described in detail. Such as Figure 8 As shown, the airtight membrane body 41 of the safety self-closing assembly 4 can be set to be made of elastic material only at the sealing place of the opening 421 on the side of the guide liquid 42, while other parts can be made of hard materials or directly connected with the guide liquid. The liquid is integrally formed, but it is necessary to ensure that the medicinal liquid in the liquid 43 can open the airtight membrane 41 with its own gravity, so that the medicinal liquid can flow into the infusion hose 2 from the opening 421 on the side of the liquid guide. Using this embodim...

Abstract

The invention relates to a disposable self-closed safety infusion device and belongs to the field of medical devices. The disposable self-closed safety infusion device comprises a bottle inserting needle, a drop tube, an infusion hose, an infusion needle, a dosing tube and a breather tube, wherein the outside of the infusion hose is sleeved with a flow rate regulator for controlling the flow rate of liquid; one or more self-closed safety components are arranged in the drop tube and / or between the infusion hose and the drop tube. The disposable self-closed safety infusion device has the benefits that when the infusion is about to an end, the self-closed safety component can automatically close an infusion pipeline to prevent air from entering a patient body; the pressure in the infusion pipeline cannot be reduced, and blood in an artery and a vein cannot flow back into the infusion pipeline and / or an infusion bottle, so that the propose of safe infusion is really achieved; meanwhile, the disposable self-closed safety infusion device is simple in structure and is convenient and simple to operate.

Description

technical field [0001] The invention relates to an infusion device for intravenous and arterial infusion for patients in the medical field, in particular to a disposable safety infusion device which can automatically seal the infusion pipeline. Background technique [0002] At present, all medical units use disposable infusion sets when infusing patients, which is convenient and can effectively prevent the mutual transmission of diseases. However, this disposable infusion set has its disadvantages. When the liquid medicine delivery is about to be completed, the infusion line cannot be automatically closed so that the pressure of the infusion tube is lower than the pressure in the blood vessel, causing the patient's blood to pour into the infusion tube to cause coagulation. When the medical staff is not careful, a large amount of air may be injected into the patient's body, causing blood clots or air embolism in the patient, which is life-threatening. [0003] At present the...
