Description
Technical field
The invention belongs to field of medical technology, relate to a kind of transfusion bag, particularly a kind of filtering type transfusion bag.
Background technology
Transfusion is required for adding one or more medicines in transfusion bag each time in the treatment, but the particulate matters such as the bacterial virus in rubber stopper chip, medicine crystallite, dust that process formed that make up a prescription in the production of infusion solutions and Clinical practice cannot be avoided. Up to now, in the process of making up a prescription, to transfusion bag (or infusion bottle) interior dosing, dosing is directly thrust simply by syringe needle, microgranule together enters in transfusion bag in company with medicine and pollutes, therefore when transfusion, these microgranules enter human body in company with medicinal liquid, can bring many untoward reaction to patient, it is therefore necessary to remove these impurity.
In order to solve the problems referred to above, Chinese patent discloses a kind of single use bag transfusion system [application number: 200420080679.1; Notification number: CN2735993Y], it is provided with the transfusion bag indicating volume scale, transfusion bag lower end is connected with dropping funnel, liquid medicine filter and intravenous needle in turn by downcomer, equipped with actuator on the downcomer between dropping funnel and liquid medicine filter, equipped with actuator on the upper conduit of transfusion bag upper end. The granule foreign material that this single use bag transfusion system is blended in medicinal liquid by arranging liquid medicine filter to guarantee when transfusion are filtered, improve safety during transfusion.
But, liquid medicine filter is arranged at the transfusion bag lower end conduit for infusing by above-mentioned single use bag transfusion system, and conduit is also associated with dropping funnel and actuator etc., thus make the profile of whole transfusion device compares unsightly, structure is also more complicated, and conduit is all directly exposed to outer, it is easily caused supravasal liquid medicine filter before transfusion, just has occurred and that breakage, and whether medical personnel also cannot detect liquid medicine filter when to patient infusion and can normally use, especially the bag that infusion solutions have to be imported when being and infuse bag transfusion system of inconvenience could be infused, therefore practicality is not high.
Summary of the invention
It is an object of the invention to the problems referred to above existed for existing technology, it is proposed that a kind of practicality height, the filtering type transfusion bag that can effectively medicinal liquid be filtered.
The purpose of the present invention can be realized by following technical proposal: a kind of filtering type transfusion bag, including the bag for containing medicinal liquid, it is characterized in that, described bag has tubular connection seat, it is axially arranged with filter membrane and filter membrane along it in described connection seat and is divided into, by connecting seat, two cavitys that left and right is adjacent: dosing chamber and transfusing chamber, above-mentioned dosing chamber communicates with bag, and described transfusing chamber communicates with the external world and is provided with the plug being sealed against in the port of transfusing chamber.
Under unused state, the exit in transfusing chamber and dosing chamber is sealed by plug, and such medicinal liquid will not be leaked out by the outlet of transfusing chamber. When needs are infused, firmly the syringe needle of tube for transfusion is inserted in transfusing chamber through plug, owing to filter membrane is between dosing chamber and transfusing chamber, therefore when medicinal liquid can be filtered when entering into transfusing chamber from dosing chamber, this makes it possible to be filtered out by the particulate matter in medicinal liquid well. Certainly, except filtering type transfusion bag, it is also possible to the connecting base structure with filter membrane is applied on infusion bottle and forms filtering type infusion bottle.
In above-mentioned filtering type transfusion bag, described connects connecting portion and the tubular pedestal that seat includes matching with bag port, and above-mentioned plug is connected in pedestal port.
In above-mentioned filtering type transfusion bag, there is in described pedestal tubular buckling piece one and buckling piece two, described dosing chamber is positioned at buckling piece one, described transfusing chamber is positioned at buckling piece two, above-mentioned buckling piece one and buckling piece two match with pedestal inner chamber after fastening and buckling piece one and buckling piece two sidepiece communicate, and above-mentioned filter membrane edge is pressed between buckling piece one and buckling piece two.
When assembling, filter membrane is placed between buckling piece one and buckling piece two, then passes through and buckling piece one and buckling piece two are fastened mutually and makes filter membrane be fixed.
In above-mentioned filtering type transfusion bag, the fastening place of described buckling piece one sidepiece has recessed positioning recess one, the fastening place of described buckling piece two sidepiece has recessed positioning recess two, after buckling piece one and buckling piece two fasten, between filter membrane and positioning recess one and between filter membrane and positioning recess two, it is respectively provided with the cavity entered for medicinal liquid.
In above-mentioned filtering type transfusion bag, described buckling piece one has recessed fastening recess close to positioning recess one place, described buckling piece two has protrusion and with fasten the fastening plush copper that recess matches, above-mentioned filter membrane edge is pressed on fastening recess and fastens between plush copper. By fastening recess and what fasten plush copper cooperates so that buckling piece one and buckling piece two can snap together mutually.
In above-mentioned filtering type transfusion bag, described pedestal is cylindrically.
In above-mentioned filtering type transfusion bag, described buckling piece one sidepiece has the through hole one run through, and described buckling piece two sidepiece has the through hole two run through.
Buckling piece one and buckling piece two can facilitate the turnover of medicinal liquid after fastening by the through hole two of the through hole one of buckling piece one sidepiece and buckling piece two sidepiece.
In above-mentioned filtering type transfusion bag, described through hole one is positioned at positioning recess one place, and described through hole two is positioned at positioning recess two place.
After fastening with buckling piece two due to buckling piece one, filter membrane is positioned between positioning recess one and positioning recess two, and because through hole one is positioned at positioning recess one place and through hole two is positioned at positioning recess place, when such medicinal liquid passes in and out between through hole one and through hole two, it becomes possible to filtered membrane filtration.
In above-mentioned filtering type transfusion bag, one end of described buckling piece one communicates with above-mentioned bag, and one end of described buckling piece two is closed, and the other end of described buckling piece one and buckling piece two is all sealed by above-mentioned plug.
In above-mentioned filtering type transfusion bag, described pedestal port is fixed with bottle cap, and described bottle cap cylindrically and within it has the gear edge protruded ringwise, and above-mentioned plug is pressed between gear edge and pedestal port. Gear inside bottle cap is along being fixed between bottle cap and pedestal by plug, accordingly even when when the syringe needle of tube for transfusion is through plug, the port of pedestal can be sealed up all the time by plug without generation transposition.
Compared with prior art, this filtering type transfusion bag connects seat by connecting one on bag, filter membrane is arranged in connection seat, the structure not only making transfusion bag overall is simpler, and profile is also more attractive in appearance, filter membrane is hidden in connection seat well, and such filter membrane will not be damaged again, can functioning well as filtration in use, safety is higher.
