RU2415682C1 - Draining device for pleural cavity - Google Patents

Abstract

FIELD: medicine.

SUBSTANCE: invention relates to medical equipment and can be applied at cavity operations. Draining device for pleural cavity contains draining tube and external fixer to chest wall, made in form of plate with opening. Draining tube is made with extension on the end. In tube wall made are longitudinal canals, their free butts are open on extended tube end. Peripheral end of draining tube is connected with transitional bush, provided with ring-shaped canal, which is connected with force branch pipe, through which washing liquid gets into longitudinal canals. Output branch pipe of bush is connected with tube which removes, washing liquid together with pleural liquid out of central canal.

EFFECT: expansion of functional possibilities due to additional introduction of pleural cavity washing simultaneously with drainage; increase of washing quality as a result of absence of limits on washing time and volume of introduced liquid.

Description

The invention relates to medicine and can be used to improve the quality of treatment during abdominal operations.

A device that implements a method of valvular drainage (V. I. Struchkov. "Purulent surgery". M: "Medicine". 1967. S.262-263), including drainage operations with subsequent fixation of the drainage tube to the chest wall, donning on the peripheral the end of a valve valve tube made from the finger of a rubber glove, lowering it into a bottle of antiseptic liquid.

The disadvantages of this device are the limited functionality associated with the need to wear a container to collect pleural fluid and the inability to visually monitor the condition of the pleural cavity.

The prototype of the invention is a device that implements a method of drainage of the pleural cavity, containing a trocar, a tubular follower, a drainage tube with a corrugation, and the corrugation is equipped with an external clamp made in the form of a plate with a hole (patent RU No. 2270039, 2006). The disadvantages of the known device are the limited functionality and inconvenience of its operation, associated with the need to carry the patient capacity for the removed fluid.

The objective of the invention is to develop a device to improve the convenience of its operation, to simplify the method of rehabilitation and increase its effectiveness.

The technical result is the expansion of the functionality of the device, improving the quality of washing.

The specified technical result is achieved by the fact that in the drainage device for the pleural cavity containing the drainage tube, an external fixator to the chest wall, made in the form of a plate with a hole, according to the invention, the drainage tube is made with an extension of the central end, longitudinal channels are made in the tube wall, free ends which are open at the expanded end of the tube, the peripheral end of the drainage tube is connected to the adapter sleeve provided with an annular channel connected to the discharge pipe, black of that washing liquid enters the longitudinal passages, the sleeve and the outlet conduit connected to the discharge tube of the outlet channel central washing liquid together with the pleural fluid.

The drawing shows a diagram of the proposed device.

A tube 2 is inserted into the opening of the chest wall 1. The end of the tube 2 has an extension 3. In the walls of the tube 2 there are longitudinal capillary channels 4. A gauze napkin 5 and a disk 6 are used to secure the tube. An adapter sleeve 7 is put on the free end of the tube 2, in which an annular channel 8 is made. The sleeve 7 is equipped with an outlet pipe 9 connected to the outlet pipe 10. The pipe 11 is connected to the annular channel 8. The discharge pipe 12 is put on the pipe 11.

The device operates as follows.

Through the hole in the chest wall 1, the end of the drainage tube 2 with extension 3 is folded into the pleural cavity. Inside the pleural cavity, the expanded end 3 is released and straightened under the action of the elasticity of the material of the tube 2. On the outside of the chest wall 1, a gauze napkin 5 and a fixing disc 6 are put on the tube 2. Fluid for washing the pleural cavity is pumped through the tube 12. The fluid through the channel of the pipe 11 and the annular channel 8 of the sleeve 7 enters the longitudinal channels 4 of the tube 2, and then through the open ends of the channels 4 in the expanded part 3 of the tube 2 is injected into the pleural cavity. In the process of washing the pleural cavity, the washing fluid together with the pleural fluid enters the central wide channel of the tube 2 and is discharged by the tube 10 through the central hole of the sleeve 7 and the pipe 9. The washing process of the pleural cavity is not limited in time and volume of the washing fluid. After the washing procedure, the tube 12 is removed from the pipe 11 and a plug is put on it. In the period between flushing, the device acts as a normal drainage.

Compared with known devices of a similar purpose, the proposed technical solution has the following advantages:

- expanded functionality due to the additional introduction of washing the pleural cavity simultaneously with drainage;

- improved flushing quality due to the absence of restrictions on the flushing time and the volume of injected liquid;

- the introduction of washing does not interfere with the implementation of the main - drainage - function of the device.

In general, the proposed device, having a fairly simple design and ease of maintenance, can improve the quality of sanitation of the pleural cavity and reduce the recovery time of the patient.

Claims (1)

A draining device for the pleural cavity, containing a drainage tube, an external fixator to the chest wall, made in the form of a plate with an opening, characterized in that the drainage tube is made with an extension of the end, longitudinal channels are made in the wall of the tube, the free ends of which are open at the expanded end of the tube, the peripheral end of the drainage tube is connected to the adapter sleeve provided with an annular channel connected to the discharge pipe, through which the washing liquid enters the longitudinal channels, and the output a new sleeve of the sleeve is connected to a bypass tube, which drains the washing fluid from the central channel together with the pleural fluid.
