SU108312A1 - Universal device for indirect blood and blood replacement fluids transfusions - Google Patents

Description

The subject of the invention is a universal apparatus for the indirect transfusion of blood and blood-displacing liquids with irrigation devices mounted on a sliding stand and ampoules connected through piping systems with OR cannulas for intravenous or intra-arterial infusion.

The known blood transfusion apparatus is designed to perform one OR several similar functions, for example, only intravenous or intraarterial blood and blood-substituting fluids, drip transfusion, and the like; thus, the simultaneous or sequential carrying out of the various manipulations mentioned is possible ONLY provided that several different devices are used.

The proposed apparatus allows it to be used in all cases of indirect blood transfusion and blood, their fluids and is essentially universal.

The device is made with devices mounted on its tripod.

For intravenous and intraarterial injections of blood and blood mixture, Ayush, their fluids, as well as for measuring the internal pressure of the patient in the process of blood transfusion, connected with independent air ducting systems, allow these devices to be used both separately and simultaneously.

The drawing shows a diagram of a universal device.

A sliding tripod / mounted devices I FOR intravenous blood and blood mixture, oral l: fluid and device P for intra-arterial blood, connected to an independent air duct w, they systems P1 and IV.

The IV device for intravenous infusion consists of one constant irrigator 2 (a glass jar with a tube) and two standard ampoules 3 connected with canned blood OR blood-substituting liquids connected during operation. These containers are connected by rubber tubes 4 with clips 5 and 5 to a glass mixer 7 fitted with

8, with a glass cannula 9 or injection needle. For measuring pressure, there is a JO gauge connected to mixer 7 through a tube // using a tee 12 and a rubber tube / 5 with a mora clamp.

The device II for intra-arterial pumping blood contains a blood ampoule M, to which a glass tank J6 with a hole 17 for air passage, connected by a rubber tube 18 with a glass cannula 19 or a needle, is connected through a rubber tube J5.

Ampoule 14 can be connected to an air-conducting system III, in which a rubber band 20 serving as a compressor is pressurized, measured by mymeter 21.

System III includes in series: a glass cotton filter 22, a glass counter filter filled with 70 ° alcohol 23, a glass cotton filter 24, a one-way air valve 25.

The air conduction system IV serves to supply air to the tanks (irrigators) and consists of three disconnected rubber tubes 26, each of which has a glass filter counter 27 and an air spot 28 regulating the air flow.

The device makes it possible to transfuse several solutions of different compositions simultaneously, sequentially or combined, and also to simultaneously perform intravenous and intraarterial blood transfusions to one patient in combination with any solution that varies in practice, R amounts from I to 250 ml per 1 minute, and also measure the patient's vnutrisredy pressure in the process of blood transfusion or blood substitutes.

Subject invention

Universal device for indirect blood transfusion and blood flow, liquid fluids with irrigation devices and ampoules mounted on a sliding stand, connected through piping systems with cannulas or needles for intravenous or intraarterial infusions, and that, in order to obtain the possibility of using the same apparatus in all cases of blood transfusion, it is made with devices for intravenous and multiarterial blood injections and blood dosing; as well as for measuring the intravascular pressure in a patient in the process of transfusion of blood, connected to independent air-conducting systems, allowing them to use these devices both separately and simultaneously.
