SU278040A1 - CAMERA FOR INDIVIDUAL BAROTHERAPY - Google Patents

Description

The invention relates to medical equipment.

The known chambers for individual baroterans, containing the chamber itself and a source of constant pressure, do not allow the patient to inject medicinal solutions, to infuse or take blood samples during a barotherapy session without depressurization of the chamber.

The proposed chamber differs from the known ones in that its design provides for the introduction of medicinal solutions to the patient, as well as the infusion or sampling of blood without depressurization of the chamber. It is achieved that the chamber contains a dropping system, placed in a sealed cup, communicating with the chamber and a source of new pressure, and a syringe with a syringe, which is under pressure, corresponds to the pressure inside the chamber, and the droplet system and syringe draw a common lead into the chamber, for example, through injection cannula.

In addition, to fill the drip system during a session, the chamber may have a gateway made in the form of a vessel with a lid; which communicates with the chamber and the capacity of the drip system. To adjust the pressure on the syringe stem to the pressure inside the chamber, it is advisable to pull the syringe rod into the stem of the additional syringe, the piston space of which communicates with the chamber.

The drawing in Fig. 1 schematically shows the described camera, a general view. The opa contains an own chamber / drip system, placed in a sealed cup 2, connected by tube 3 and tap 4 to the chamber /, and tap 5 is connected to the atmosphere or another source of pressure. The upper vessel 6 of the drip system is closed in a glass with a basket. 7. The transfusion solution is delivered to the patient by the intermittent vessel 8 through fitting 9, stainless steel tube 10, three-way valve //, non-passable J2, tubing 13 and cannula 14.

The flow rate of the fluid to be poured is controlled by changing the cross section of the elastic pipe 15 with the rod 16.

To fill the drip system during the session, an ally is applied, vypoliyinny in vnde vessel 17 nz stainless steel with a nakndny cap-nut 18. The gateway communicates with the camera 1 with a 19 N crane with the upper vessel 6 - the crane 20.

The difference in pressure in a 2n glass in chamber 1 is recorded by a differential pressure gauge 21. A part of the device, intended for jet transfer of the solution and for taking samples for analysis, includes two syringes 22 and 23, which are contained in RZD. Syringe 23 constantly

fixed in the position shown in the drawing, n is communicated by the tube 24 to the cavity of the chamber /. Its piston is located at the far right. The cannula of the syringe 22 with the drug is connected to the three-way valve 11. The rods of both syringes are interconnected.

During the operation of the drip system, the taps 5 and 2 (9 must be closed and the valve 3 is opened to equalize the pressure in the glass 2 and chamber 1. To fill the upper vessel 6 with a new porn medicinal solution, unscrew the lid 18, pour 17 solution n into the vessel , after screwing the cap, the valve 19 is opened. In this case, the pressure in the gateway becomes equal to the pressure in the chamber. Then, opening the valve 20, it is filled with 6 solution, which passed through the tube 15, intermediate vessel 8, fitting 9, tube 10, crane 11, non-adapter 12, flexible tube 13 and cannula 14, bol is inserted Nomu.

The constant flow rate of the solution poured over to the patient is ensured by the constancy of its level in the intermediate vessel 8. If it is necessary to accelerate the introduction of the patient's medicinal drugs or blood infusion to him, in glass 2 they create an excessive pressure relative to the open mirror. liquids in vessel 6. To do this, connect the gas 2 through a valve 5 with a higher pressure outlet (before this the valve 4 must be closed).

In case of emergency, medication (or blood infusion) is used for the injection of two syringes 22 and 23 on the GUM01CP. This system can also be used to collect venous blood through a catheter inserted into the patient's vein.

Before entering the system, the valve 25 is opened and the cavity under the piston is reported

width 23 with chamber cavity. Then the three-way valve is placed in position, in which the cavity of the node with the piston of the syringe 22 is connected to the drip system, and by moving the syringe rods to the left, the air from the syringe 22 is pushed into the drip system. The same three-way valve 11 connects the cavity of the syringe 22 to the patient's vein (via adapter 12, tube 13 and cannula 14), then the medicine is injected.

The piston of the syringe 23 is retracted to its original position, together with its cavity and atmosphere, using a crane 25.
