In the infusion device with the heat preservation and air leakage prevention effects, the buoyancy plug is in a spherical structure in an inflated state and is in a cylindrical structure in a shriveled state, and the buoyancy plug is connected with the cylinder structure in a compressed state.
Compared with the prior art, the invention has the advantages that:
1. according to the invention, the hollow buoyancy plug is arranged in the hanging pipe, so that the problem of thrombus caused by inputting air into veins can be solved, before infusion, the interior of the buoyancy plug is in a shriveled state, and the gas in the buoyancy plug is less, so that iron powder in the heating layer is attracted by the magnet ring, is positioned at the bottom of the exhaust funnel and is in an initial state;
2. after the hanging tube is connected with an infusion bottle, liquid medicine enters the exhaust funnel under the action of gravity, and air is input into the buoyancy plug through the air cylinder, so that on one hand, a cavity in the buoyancy plug is filled with air to expand outwards, a cylindrical structure is changed into an inflated spherical structure from an initial state, on the other hand, relative density is reduced after the volume of the buoyancy plug is increased, and the density of the buoyancy plug is smaller than that of the liquid medicine and is subjected to buoyancy;
3. in the inflation process, the volume of the cavity is increased, so that the inner wall of the buoyancy plug of the rubber structure is thinned, the airflow channel is gradually extruded, the airflow channel which is originally connected with the air inlet in a sealing way is separated from the air inlet, and the buoyancy plug is finally separated from the air cylinder and floats on the surface of the liquid medicine under the buoyancy action of the liquid medicine;
4. meanwhile, the air input into the cavity and the iron powder generate oxidation-reduction reaction and slowly release heat, so that the heating effect of the buoyancy plug is realized, the liquid medicine is continuously kept warm after the buoyancy plug is heated, the liquid medicine input into a human body is prevented from being too cold to cause discomfort to a certain extent, and meanwhile, the iron powder is less in quantity and cannot generate larger heat to cause danger;
5. buoyancy stopper after the inflation is in the ball-type state, and when using, the infusion bottle gets into the aiutage and gets into with the liquid drop form, then the liquid drop all can have a pushing down effect to the buoyancy stopper that is located the liquid medicine top when getting into the aiutage, can make the inside vibration that produces a small range of buoyancy stopper like this, thereby make the iron powder vibrate, improve the area of contact with the input air, and improve the reaction degree of iron powder, also make the buoyancy stopper maintain a heating state all the time, and after the infusion is accomplished, the cavity bottom can have the iron powder that the part does not react all the time, can make the buoyancy stopper when being located the aiutage bottom like this, the iron powder is automatic to be attracted by the magnet ring, improve the sealed effect of buoyancy stopper.

Detailed Description
The following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.
Examples
Referring to fig. 1-2, an infusion apparatus with heat preservation and air leakage prevention effects comprises an infusion bottle 1 and a hanging tube 4, wherein one end of the hanging tube 4 is fixedly connected with a sealing plug with a cone structure, the other end of the hanging tube 4 is connected with a needle tube, one part of the hanging tube 4 is provided with an exhaust funnel 3, the bottom of the exhaust funnel 3 is connected with a buoyancy plug 5, a cavity is formed inside the buoyancy plug 5, the bottom of the buoyancy plug 5 is provided with an air inlet hole, the air inlet hole is connected with an air cylinder 7 in a sealing manner, the air cylinder 7 consists of a cylinder body, a valve rod and an exhaust port, the exhaust port part of the air cylinder 7 is connected with the air inlet hole in a sealing manner, the cylinder body of the air cylinder 7 penetrates through the bottom of the exhaust funnel 3 in a sealing manner, the valve rod and a push plate part are positioned outside the exhaust funnel 3;
the zone of heating 9 comprises ventilated membrane and the iron powder of placing on the ventilated membrane, and keep relative vacuum under shrivelled state, and the iron powder has the effect of slow oxidation in the air, and exothermic effect, the inlet port sealing connection on the buoyancy stopper 5 has the check valve, buoyancy stopper 5 adopts rubber materials to constitute, have deformation space, make self volume can expand under the gas filled state, the one end that the inlet port is located buoyancy stopper 5 is equipped with airflow channel 8 and airflow channel 8's the other end is located the right side wall of cavity, buoyancy stopper 5 is in the ball-type structure under the gas filled state and is in the cylinder type structure under the shrivelled state, make after aerifing, relative density reduces after self volume expansion in the aspect of buoyancy stopper 5, can float on the liquid medicine surface, on the other hand, ball-type buoyancy stopper 5 more easily produces the vibration in-process that the liquid droplet fell.
When the invention is used, in an initial state, only the heating layer 9 is arranged in the cavity, and a relative vacuum state is kept, at the moment, the magnet ring 6 attracts iron powder, so that the buoyancy plug 5 is fixed at the bottom of the exhaust funnel 3, after the infusion bottle 1 is connected with the hanging tube 4, the buoyancy plug 5 is inflated through the air cylinder 7, so that the buoyancy plug 5 expands, the density of the buoyancy plug 5 gradually decreases, and finally the buoyancy plug can float on liquid medicine and overcome the attraction of the magnet ring 6 to the iron powder, and simultaneously the iron powder and the air entering the cavity release heat after undergoing an oxidation reduction reaction, so that the effect of continuously heating the liquid medicine is achieved, and in the reaction, as liquid drops continuously drop on the buoyancy plug 5, the vibration of one buoyancy period always exists in the cavity of the buoyancy plug 5, so that the reaction area of the iron powder and the air is increased in the vibration.
When the invention is used, after the hanging tube 4 is connected with the infusion bottle 1, the liquid medicine enters the exhaust funnel 3 under the action of gravity, and then air is input into the buoyancy plug 5 through the air cylinder 7, on one hand, the cavity in the buoyancy plug 5 is filled with air so as to expand outwards, so that the cylindrical structure is changed into the inflated spherical structure from the initial state, on the other hand, the relative density is reduced after the volume is increased, so that the density of the air flow is smaller than that of the liquid medicine, the air flow channel is gradually closed in the process that the inner wall of the buoyancy plug 5 is extruded, an internal closed structure is formed, and the air in the cavity gradually reacts with iron powder in the heating layer to generate heat and is transferred into the liquid medicine, so that the effects of heat preservation and proper heating are achieved;
after the liquid medicine in the infusion bottle 1 is used up, if a patient does not find the liquid medicine, the liquid level of the hanging tube 4 continuously descends to enable the buoyancy plug 5 to be finally positioned at the bottom of the exhaust funnel 3, the unreacted iron powder at the bottom of the cavity of the buoyancy plug 5 is attracted by the magnet ring 6 to seal the part, below the air cylinder 7, of the hanging tube 4, the liquid level cannot continuously descend, the problem that the blood flows out of the needle tube under the action of the blood pressure after the liquid medicine is completely input and the blood coagulation is caused under the condition that the blood cannot flow back for a long time is solved, and the danger caused by the fact that the air is directly.
Although the terms of the infusion bottle 1, the connection plug 2, the exhaust funnel 3, the hanging tube 4, the buoyancy plug 5, the magnet ring 6, the air cylinder 7, the air flow passage 8, the heating layer 9, etc. are used more extensively herein, the possibility of using other terms is not excluded. These terms are used merely to more conveniently describe and explain the nature of the present invention; they are to be construed as being without limitation to any additional limitations that may be imposed by the spirit of the present invention.
