Abstract
The utility model relates to an infusion bottle cap capable of preventing air pollution. The utility model comprises a bottle stopper and a bottle hoop for fixing the bottle stopper. An air guiding pipe and a transfusion pipe are inserted into the bottle stopper. The bottle stopper is divided into a bottle stopper part for inserting the air guiding pipe and a bottle stopper part for inserting the transfusion pipe. The two parts are fixed to an infusion bottle by the bottle hoop. A watertight and gastight flexible bag is fixed to the inner side of the bottle stopper part for inserting the air guiding pipe. An entrance of the air guiding pipe, which is towards the infusion bottle is contained in the bag. The utility model is characterized in that harmful substances in external air is prevented from inputting into a patient body. In addition, the therapy effect of input liquid is not changed. The gastight performance of the bottle stopper is enhanced. The utility model is suitable for medical infusion.
Description
This utility model relates to a kind of infusion set of medical field.
At present, the transfusion device that each hospital extensively adopts, in the process of patient body's angular vein input liquid, along with the liquid of infusion bottle is constantly imported human body, gas pressure reduces gradually in the bottle, therefore, the outer gas of bottle constantly adds in the bottle by existing infusion set, can have enough pressure to enter the vein of human body to guarantee the liquid in the bottle.In this process, outside air will be inevitably mixes with liquid phase existing, that be about to be transfused to human vein in the bottle, is cleaned by liquid, thereby, this harmful substances in air might be detained in the liquid, and then the process by in the patient body, infusing, human vein entered.Existing transfusion device usually adopts and install methods such as filter membrane or filter screen additional in its airway, playing all harmful substances in the filtered air, thereby can not thoroughly eliminate the probability that harmful substance enters venous patient by institute's transfusion in the air.
The purpose of this utility model provides a kind of air pollution Infusion bottle lid that prevents, with ambient atmos with to be about to import the intravital liquid of people thoroughly isolated, thereby when not changing institute's transfusion therapeutic effect, can thoroughly avoid the harmful substance in the outside air to be transfused in the patient body again.
This utility model prevents that the technical scheme of air pollution Infusion bottle lid from being:
Prevent the air pollution Infusion bottle lid, comprise the bottle stopper and the fixing bottle hoop of bottle stopper, can be inserted with airway and tube for transfusion on the bottle stopper, it is characterized in that: bottle stopper is separated into inserts airway bottle stopper part and slotting tube for transfusion bottle stopper part, two parts are fixed on the infusion bottle by the bottle hoop, the bag attachment of a waterproof airtight flexibility is inboard in the bottle stopper part of inserting airway, the inlet of airway in infusion bottle is included in the sack.
It partly is half truncated cone-shaped or truncated cone-shaped that above-mentioned bottle stopper is inserted airway.
The separation rib of separating two parts bottle stopper is arranged on the above-mentioned bottle cap.
The edge of opening of above-mentioned sack is pressed abd fixed between bottle cap and the bottle stopper.
The material of above-mentioned sack is plastic sheeting or rubber film.
Infusion process of the present utility model: liquid in the bottle is because the combined effect of original gas in gravity and the bottle, constantly enter in the human vein by catheter, because liquid level is more and more lower, the volume of original gas constantly increases in the bottle simultaneously, the suffered pressure of the inside of a bottle of sack is reduced gradually, so the outer gas of bottle (1 atmospheric pressure) of constant voltage constantly enters in the sack by airway, the volume of gas in the sack is constantly increased, the pressure of this gas passes to a bottle interior liquid by sack, thereby kept the pressure of the interior liquid of bottle at the tube for transfusion place, this process is retained to bottle interior liquid always and all flows out.
This utility model has improved the transfusion device bottle cap, with ambient atmos with to be about to import the intravital liquid of people thoroughly isolated, thereby when not changing institute's transfusion therapeutic effect, can thoroughly avoid the harmful substance in the outside air to be transfused in the patient body again.In addition, the sack of collecting gas in the bottle is to the bottle stopper opening, and is fixed on the bottle cap, has improved the sealing property of bottle cap effectively.Be applicable to medical transfusion.
Below in conjunction with drawings and Examples this utility model is described in detail:
Fig. 1 adopts the working state schematic representation of transfusion device of the present utility model when beginning to infuse.
Fig. 2 adopts the working state schematic representation of transfusion device of the present utility model in infusion process.
Fig. 3 is the structural representation that this utility model prevents the air pollution Infusion bottle lid.
Fig. 4 is the vertical view of Fig. 3.
As shown in the figure, prevent the air pollution Infusion bottle lid, comprise the bottle stopper 2 and the fixing bottle hoop 4 of bottle stopper, can be inserted with airway 3 and tube for transfusion 5 on the bottle stopper, bottle stopper 2 is separated into inserts airway bottle stopper part and slotting tube for transfusion bottle stopper part, two parts are fixed in by bottle hoop 4 on the bottleneck of infusion bottle 7, and it partly is half truncated cone-shaped or truncated cone-shaped that bottle stopper is inserted airway.The sack 1 of a waterproof airtight flexibility is fixed on the bottle stopper part inboard of inserting airway, the inlet of airway 3 in infusion bottle is included in the sack 1.On the bottle hoop 4 separation rib 6 of separating two parts bottle stopper can be arranged, the edge of opening of sack 1 is pressed abd fixed between bottle hoop 4 and the bottle stopper 2.The material of sack 1 is plastic sheeting or rubber film.
