Abstract
The invention relates to an infusion set capable of filtering air, which comprises a bottle cork puncture outfit, a dropping funnel, a liquid flow regulator, a liquor filter and a vein needle which are connected in series through infusion catheters, wherein the infusion catheter below the dropping funnel is connected with an air filter. The air filter is composed of an upper shell, a lower shell and a hydrophilic filter membrane, and the hydrophilic filter membrane is sandwiched between the upper shell and the lower shell. The hydrophilic filter membrane immersed by water is non-watertight and airtight, thereby performing the function of air filtration. The air filter provided by the invention is positioned in front of the liquor filter, and thus, can remove bubbles before the liquor enters the liquor filter, thereby preventing the bubbles from entering the vessels of the patient; and therefore, the infusion is safer. Meanwhile, the invention reduces the work intensity of nursing personnel, is more convenient for operation, saves time and labor, and enhances the work efficiency. Thus, the invention provides an ideal infusion set capable of filtering air.
Description
Technical field
The invention belongs to medical mechanical domain, a kind of specifically gas transfusion device of filtering.
Background technology
We know; Disposable infusion set is the medical apparatus and instruments of using always; Comprise bottle plug puncture unit, dropping funnel, fluid flow regulator, liquid medicine filter, intravenous needle as the one of which, they be chained together that liquid medicine filter generally is made up of upper and lower casing and microporous filter membrane purifying layer by transfusion catheter; The microporous filter membrane purifying layer is clipped between the infundibulate upper and lower casing, and medicinal liquid is filtered, purifies.Owing to dosing in the infusion process and other reason; Deposit minute bubbles through regular meeting's collection in various degree in the medicinal liquid, beat even filter is carried out bullet, bubble also is difficult for emptying; The part bubble can get in the patient vessel along with medicinal liquid; This has not only influenced patient's physiological health, has also influenced mental health, makes the patient produce psychological doubt and fear to a certain extent.Therefore, medical personnel will in time drive the bubble in the medicinal liquid out of, to guarantee transfusion safety.And present liquid medicine filter is not easy to carry out aforesaid operations.
Summary of the invention
Technical problem to be solved by this invention is the deficiency that overcomes above-mentioned prior art; Provide a kind of rational in infrastructure, easy for operation, can effectively the bubble in the medicinal liquid be filtered out; Eliminate the phenomenon of air admission patient's blood vessel, make the more safe and reliable gas the filtered transfusion device of transfusion.
The technical scheme that the present invention solves the problems of the technologies described above employing is: a kind of gas transfusion device of filtering; Include bottle plug puncture unit, dropping funnel, flow regulator, liquid medicine filter, intravenous needle; By transfusion catheter they are chained together, it is characterized in that: connect an air filter on the transfusion catheter of said dropping funnel below.
Said air filter is made up of upper shell, lower house and hydrophylic filter membranes, and hydrophylic filter membranes is clipped between upper shell, the lower house.After hydrophylic filter membranes is soaked in water, permeable airtight, can play airfiltering effect like this.
The present invention is owing to be connected an air filter between dropping funnel and flow regulator; It is positioned at before the liquid medicine filter, and against existing technologies, the present invention can be with the bubble emptying before medicinal liquid gets into liquid medicine filter; Avoid bubble to get in the patient vessel, make transfusion safer; Alleviated nursing staff's working strength simultaneously, more convenient operation, time saving and energy saving, improved work efficiency.It is a kind of ideal gas transfusion device of filtering.
Description of drawings
Below in conjunction with accompanying drawing the present invention is described further.
Fig. 1 is a structural representation of the present invention.
Label among the figure is: 1. bottle plug puncture unit, 2. transfusion catheter, 3. dropping funnel, 4. air filter, 5. flow regulator, 6. liquid medicine filter, 7. intravenous needle.
The specific embodiment
As can be seen from Figure 1, a kind of gas transfusion device of filtering is provided with bottle plug puncture unit 1, dropping funnel 3, flow regulator 5, liquid medicine filter 6, intravenous needle 7, by transfusion catheter 2 they is chained together.Bottle plug puncture unit 1 is provided with air induction conduit.The concrete composition structure of dropping funnel 3, flow regulator 5, liquid medicine filter 6, intravenous needle 7 and they belong to prior art with being connected of transfusion catheter 2.During use, bottle plug puncture unit 1 is inserted in the infusion bottle, the air in the emptying transfusion device pipeline advances intravenous needle 7 punctures in patient's the vein again, opens flow regulator 5 and just can carry out venous transfusion.
Characteristics of the present invention are: connect an air filter 4 on the transfusion catheter 2 of said dropping funnel 2 belows.Said air filter 4 is made up of upper shell, lower house and hydrophylic filter membranes, and hydrophylic filter membranes is clipped between upper shell, the lower house.Can be directly fixed between upper shell, lower house and the hydrophylic filter membranes through the ultrasonic heat blow.Upper shell, lower house are respectively equipped with feed pathway and liquid outlet channel.Because used filter medium is a hydrophylic filter membranes, and is after hydrophylic filter membranes is soaked in water, permeable airtight.Can play airfiltering effect like this.
Air filter of the present invention is positioned at before the liquid medicine filter, can avoid bubble to get in the patient vessel with the bubble emptying before medicinal liquid gets into liquid medicine filter, makes transfusion safer; Alleviated nursing staff's working strength simultaneously, more convenient operation, time saving and energy saving, improved work efficiency.It is a kind of ideal gas transfusion device of filtering.
Claims (2)
1. can filter the gas transfusion device for one kind, include bottle plug puncture unit, dropping funnel, fluid flow regulator, liquid medicine filter, intravenous needle, they are chained together, it is characterized in that: connect an air filter on the transfusion catheter of said dropping funnel below by transfusion catheter.
2. the gas transfusion device of filtering according to claim 1 is characterized in that said air filter is made up of upper shell, lower house and hydrophylic filter membranes, and hydrophylic filter membranes is clipped between upper shell, the lower house.
