Description

Anti-drop transfusion system of integrated function of admitting air

Technical Field

The utility model relates to the technical field of medical equipment, concretely relates to integrated anti-drop transfusion system who admits air function.

Background

Intravenous injection therapy is to drip medicine into blood vessels of human body through an infusion apparatus in an intravenous infusion mode, and is one of the most widely used clinical treatment modes at present. However, in the using process, the infusion apparatus is easy to fall off due to being pulled by external force, and the infusion apparatus is polluted, and if the patient is self-treated or not treated in time, the injection infection of the patient is easily caused.

The reason why the infusion apparatus is easy to fall off by external force is mainly as follows: the structure of the transfusion device mainly comprises a steel needle inserted into a medicine bottle, a drip cup for checking the dripping speed and buffering, a simple speed regulator, a simple filter, a transfusion needle inserted into a blood vessel for transfusion and a hose communicated with all the components. The using mode is as follows: when using the transfusion system to infuse, the height that medicine bag or medicine bottle hung is higher than human head usually, and medicine bag or medicine bottle have the plug that supplies the steel needle to pierce medicine bag or medicine bottle, through hose and each part, utilize difference in height and air pressure to make the liquid medicine circulate to inserting vascular transfusion needle, and then imports human blood vessel with the liquid medicine. Influenced by the structure, the using mode, the application frequency, the service life and the like of the infusion apparatus, in the using process, the steel needle is not fixed by other fixing modes after being inserted into the rubber plug of the medicine bag or the medicine bottle, the medicine bag is only fixed by the friction force between the steel needle and the rubber plug, the medicine bag is higher than the head of a human body, inconvenience is caused in visual line observation, the hose of the infusion apparatus is often pulled by a patient to observe the infusion progress of the medicine bag, and the infusion apparatus is easily pulled by external force to fall off.

When the infusion apparatus is pulled by external force, the steel needle inserted into the medicine bottle is separated, usually falls onto the ground or a patient bed, part of patients pick up the falling steel needle, the infusion is closed through a dropping speed regulator or a clip, and then a nurse is called to replace the infusion apparatus; even some patients will insert the steel needle back into the vial themselves. However, in the process of stopping the dripping speed regulator or the clamp, the liquid in the infusion apparatus still continues to drip downwards, and the steel needle is provided with the liquid inlet, so that the liquid medicine flows out from the infusion apparatus through the steel needle and the liquid inlet. Thus, this results in: (1) when the steel needle inserted into the medicine bottle falls on the ground, if the transfusion device is not turned off in time or the patient inserts the medicine bottle, the liquid medicine in the transfusion device is polluted by the falling steel needle and the falling steel needle exposed outside, and the polluted liquid medicine enters the human body again, so that the patient is infected, the pain of the patient caused by diseases is increased, and the burden of medical care is increased; (2) when a patient infuses expensive medicines such as targeted medicines, the infusion apparatus needs to be replaced due to falling and pollution of the infusion apparatus, so that the original liquid medicine in the infusion apparatus can be abandoned and wasted, resource waste is caused, and quantitative injection monitoring of the targeted medicines is not facilitated, so that treatment of the patient is influenced; (3) when the medicine such as chemotherapy medicine is infused, the high-toxicity medicine such as chemotherapy medicine is easy to overflow to the ground or the sickbed of a patient from the steel needle, thereby polluting the surrounding environment and damaging the skin of the patient.

The existing intravenous infusion apparatus with anti-drop protection is mainly characterized in that the bottom of the bottle stopper puncture needle is connected with a fixing clamp which is C-shaped and is bent upwards, and the top of the fixing clamp is provided with a U-shaped groove, fixing hasps are installed at two ends of the U-shaped groove, and an infusion bottle can be clamped through the fixing clamp and the fixing hasps in the use process of the infusion bottle, so that the anti-drop effect is achieved. However, the patient often involves bags and bottles with various shapes and specifications during transfusion, the shape and specification of the bottle stopper opening are different, and various scenes such as changing liquid medicine and getting to a toilet of the patient are involved, so that the scheme has the problem of insufficient adaptability.

Therefore, there is a need for a design that can increase the anti-drop function, and at the same time, maintain the features of simple structure, convenient use, easy mass production, and relatively low price, and has a wide adaptability, and can be applied to infusion bags or infusion bottles of different specifications, and many application scenarios.
