Description

The invention relates to medical equipment, in particular to devices for administering drug solutions to the human body.

The aim of the invention is to increase the convenience of use in the field, the combination of two substances / in different state of aggregation in one tank.

In Fig, 2 shows the proposed device ..

SUMMARY OF THE INVENTION

A dropper bag for disposable solutions consists of a main bag made of a transparent elastic film filled with a solution, in which a second (inner) bag 2 is placed, part of which is screwed in in the form of a duplicate to form a chamber 3. The inner walls are hermetically connected along the fold line with the formation of a seam 8. The free edges of the inner bag 2, together with the free edges of the main bag 1 are connected, covering

an inlet valve 6, through which the remaining part of the bag 2 communicates with a discharge device 5, in which there is an elastic sleeve 9, Air intake is carried out through the suction valve 7, closed by a plug 18. In the bottom | part of the bag 1 there is an opening 11 to which a dropper 12 is connected with a pipe 13, a clip 4 and a pressure reducing valve with a tip 15 for the injection needle. Outside, a tape 17 is attached to the main bag to secure the bag to the patient's arm. The pipe with a clamp, a pressure reducing valve with a tip after sterilization is placed in the bag 16, hermetically closed and fastened to the bottom of the bag 1.

The blowing device 5 serves to pump air into the free part of the bag 2. Has a shell filled with an elastic sleeve (parolon. Elastic rubber) whose cavity through the channel 10 communicates with the inlet valve 6, a fence

air is carried out through a valve 7 which is closed by a plug 18.

Before use, the dropper bag must be turned so that the discharge device 5 is at the bottom, removing the plug 18 from the valve 7 and periodically squeezing the elastic sleeve, we pump air through the valve 6 into the free part of the bag 2, which inflates while the seam 8 is torn, the chamber with a drug substance that enters the solution is mixed with it. When removing the clamps 14 from the pipeline 13, it is necessary to squeeze the air out of bag 1 and, having put the clamp on the pipeline after venipuncture, connect the tip 14 to the needle cannula, the dropper bag is attached to the patient’s hand using tape 17, the clamp is removed and periodically squeezed, the pressure device 5 pumps air into the inner bag 2, which spray fills the cavity of the bag 1 With a solution squeezes
