RU2392008C2 - Suction intensity regulating device in blood-collecting units within surgical operation - Google Patents

Abstract

FIELD: medicine.

SUBSTANCE: invention belongs to medical equipment, notably to devices and units used within surgical operation for collection of effused blood and its return into patient's blood-stream. Suction intensity regulating device in blood-collecting units within surgical operation includes T-tube inserted in vacuum line from vacuum pump to blood-collecting container, and suction unit controlling pipe, one end of which is connected to T-tube nozzle and another end - to suction unit tip. On the handle of suction unit tip is mounted the pipe with inner diametre no less than 2.5 mm. Bottom side of pipe, adjacent to surface of suction unit tip, has beveled cut: another side of this pipe is connected to suction unit controlling pipe.

EFFECT: invention aimed to design simplification and operation convenience enhancement.

Description

FIELD OF THE INVENTION

The invention relates to transfusiology, in particular to devices and installations used during an operation to collect spilled blood in order to return it to a patient.

State of the art

Known installation for collecting poured during the operation of the blood, consisting of a vessel for collecting blood having at least two nozzles. One fitting has a tube connected to the handle of the suction tip, and the other fitting is connected to a vacuum source by a tube. By creating a vacuum in the vessel, blood enters the vessel. Regulation of blood suction is carried out by the presence on the handle of the suction tip of the hole in communication with the blood flow channel. The surgeon provides a partial or complete overlap of the hole with a finger, thereby regulating the intensity of the suction. The disadvantage of these installations is the passage of suction air through the vessel, regardless of the regulation provided by the finger of the surgeon, and this, in turn, due to the presence of oxygen in the air, causes hemolysis of blood already collected in the vessel.

A device is known according to the application 2004122657/14 (024415), in which the suction intensity is controlled using a tee connected to the vacuum supply line, a tube controlling the suction brought to the control handle connected to the handle of the suction tip. In this case, the control handle has a lever interacting with the end of the control tube by clamping it. The disadvantage of this design is the complexity of control, including a movable lever with a spring, as well as the inconvenience associated with the need for a finger to exert force to overcome the force of the spring. The invention is aimed at simplifying the design and improving ease of use.

SUMMARY OF THE INVENTION

A device for controlling the intensity of the suction consists of a control tube, which is connected at one end to a tee included in the vacuum supply line, and the other is connected to the handle of the suction tip.

According to the invention, a tube with an internal diameter of at least 2.5 mm is located on the handle of the suction tip along its length. At one end, the tube is connected to the suction control tube, and the other end has a slice made obliquely from its lower end adjacent to the surface of the tip handle by suction.

Options of additional execution are possible:

- the tube is located in a groove running along the handle of the suction tip;

- the suction control tube and the tube located on the handle of the suction tip represent a single unit;

- the handle of the suction tip is hollow and has an end open on one side, and on the upper part there is a convex ledge with a hole, and the tube partially lies on the surface of the handle, and partially inside it.

Description of drawings

The invention and the possibility of achieving a technical result is illustrated by the drawings, in which Fig. 1 shows a general view of the installation including the device, Fig. 2 shows the handle of the suction tip with a tube on its surface, Fig. 3 shows an option when the tube is located in the groove , Fig. 4 is an embodiment of the integral embodiment of the tube on the handle of the tip by suction, while the handle has a step with an opening for outputting the tube.

An example of a specific implementation of the invention

Installation including a device. It consists of a vessel 1, fittings 2 and 3, a vacuum source 4, a tube 5, a tee 6, a suction control tube 7, a blood supply tube 8 into a vessel 1, a suction tip handle 9, a suction tip 10. Tubes 11 of the groove 12.

Device operation

When you turn on the source of vacuum 4, the vacuum through the tube 5 through the tee 6 and the nozzle 2 is formed in the vessel 1, so that the blood through the tip 10, through the tube 8 through the nozzle 3 enters the vessel. The surgeon partially or completely closes the hole in the tube 11 with his finger, so that air enters the gap formed by the finger and the edges of the hole. The smaller the gap, the smaller the suction of air, the higher the vacuum in the vessel 1. Thus, the surgeon can control the intensity of the suction, without causing hemolysis of the blood entering the vessel 1.
