Description

DESCRIPTION

Pleural fluid drainage system

Technical sector

This invention belongs to the surgical medical equipment sector within devices for draining pleural fluid.

The main objective is safety and asepsis during the therapeutic thoracentesis procedure or pleural fluid drainage, adapting to the different calibers of pleural catheters for discontinuous drainage. It provides a complete and immobile seal of the connections between the pleural catheter and the vacuum bottle and allows control of the drainage flow, this being essential to avoid complications, in a safe and comfortable way for the medical professional.

Background of the invention

It is a system designed to carry out a therapeutic thoracentesis, a procedure indicated according to medical criteria after a medical examination and diagnostic tests such as: chest X-ray, chest ultrasound, ... where the existence of a pleural effusion is verified. Depending on its size and diagnostic orientation, a diagnostic and/or therapeutic thoracentesis will be performed.

Until now, a pleuro-puncture set is needed to perform the procedure, there are catheters of different calibers: 8-12-14-16-20Fr, which up to 14 Fr are connected to a three-way stopcock which can be connected by a 60 cc luer-lock syringe on one side and a drainage bag on the other, having to perform the extraction manually with the syringe and each time it is filled, the stopcock must be turned to deposit the pleural fluid in the collection bag. There are sets with the complete equipment (catheter, syringe, drainage bag). These techniques can be performed on an outpatient basis or with the patient admitted to the hospital.

An example of this type of set is the Turkel®8Fr/Ch commercial system.

Pleural catheters that have a caliber of 16.0 Fr or greater do not have a luer-lock connection in their distal part, they end in a conical shape so they cannot be manually drained as in the previous example and a secure connection for aspiration or intrapleural treatment.

An example of a catheter is Thal-Quick (this kit does not contain a manual drainage set).

Explanation of the invention

This document describes an improvement in the current systems for performing a therapeutic thoracentesis and, if necessary, being able to administer intrapleural treatments. Until now, therapeutic thoracocentesis or discontinuous pleural drainage has been performed manually with equipment consisting of a syringe and a collection bag that can be connected to catheters of different calibers (up to 14Fr). This utility model offers a system in which pleural fluid drainage can be performed in contrast to manual suction with a vacuum bottle,

being able to safely regulate the outflow of pleural fluid, and what is more important is that all the connections of the different parts of the system are sealed avoiding disconnections that can cause leaks or air entry into the pleural cavity. In addition to being able to administer intrapleural treatments according to medical indication. This system with the different components it consists of can be adapted to all calibers of pleural catheters with their respective connections.

The drainage system product of the invention comprises:

Drainage line (transparent, flexible, kink-resistant, disposable, non-pyrogenic tube), with luer-lock connectors at both ends and regulator roler placed on the drainage line for flow control, an adapter with two ends, a proximal one at conical shape and a distal valve with two outlets with a female luer-lock connection and a vacuum bottle. This line is prepared to connect at one end to a catheter or a three-way stopcock and at the other end to a vacuum bottle for drainage of pleural fluid with aspiration.

The main advantages of this invention are summarized as follows:

• Luer-lock connectors at both ends of the drainage line provide safety by preventing disconnection of the different parts of the system, it remains immovable at both ends (catheter and vacuum bottle), thus preventing air from entering the pleural cavity and possible complications.

• The roler located in the drainage line safely regulates the aspiration of pleural fluid, avoiding rapid re-expansion of the lung.

• The conical-shaped adapter at one end and the stopcock at the other end makes it possible to use larger caliber pleural catheters to perform therapeutic thoracentesis and administration of intrapleural treatment according to medical indication.

• As it is a transparent tube, it allows you to see the appearance of the pleural fluid (serous, haematic, • purulent...)

• Allows the pleural fluid sample to be collected from the vacuum bottle or from the stopcock.

• Provides security by preventing disconnections.

• When performing pleural fluid drainage, a system is needed that safely and sterilely connects the catheter or three-way stopcock and the vacuum bottle. The roler safely regulates the aspiration, controls and prevents rapid drainage. It avoids manipulations and adapts to different pleural catheters.

• The vacuum bottle can be changed safely by closing the regulating roller, thus preventing the entry of air into the pleural space and/or the exit of pleural fluid.

Preferred embodiment of the invention

An example of the different components of the pleural fluid drainage system is described below with reference to the attached figures. This utility model is adaptable to the different calibers of existing pleural catheters.

Following the drawings, Fig. 1 shows a drainage line, which is a flexible tube (1c), characterized by presenting at its two distal ends (1a) a male luer-lock connector that allows safe and immovable connection between the pleural catheter and the vacuum bottle, likewise contains a regulating roler (1b) that allows control of the drainage flow of the pleural fluid, thus avoiding a too rapid re-expansion of the lung and the complications that may derive from it.

Fig 2 shows an adapter which at its proximal end has a conical shape (2a), a flexible tube (2b) and at the distal end a stopcock composed of two outlets with a female luer-lock connection (2b) and a rotating key (2c) that allows the flow to be closed in each of its directions as required. This will be used when necessary in larger caliber catheters which do not have a female luer-lock connection at their distal end and cannot be connected to a vacuum system. The stopcock will also allow intrapleural treatment to be administered if necessary.

Fig 3 shows a vacuum bottle that includes a female luer-lock connection (3a) in its upper part that connects with the drainage line at its distal end (1a), allowing an immovable and secure connection, a clamp for opening (3b) to suction, the collection container (3c) with a capacity of 1000 cc and a vacuum loss indicator (3d).
