Definitions

  • the present invention refers to a drainage device, particularly suitable for pulmonary use but also applicable in other body districts, such as, e.g. the cardiac one, and to a related apparatus, preferably with modular components.
  • thoracic drainage or pleural drainage
  • thoracic drainage it is meant the suction of air or liquid infiltrations present in the pleural cavity, i.e. in the space defined between the membrane of said pleura and the pulmonary alveolar parenchyma.
  • drainage has the purpose of bringing pressure values in the intrapleural environment back to physiological conditions, removing air and liquid secretions from the cavity itself.
  • Drainage represents a fundamental surgical procedure, often indispensable for a correct treatment of some pathologies, and in particular pneumothorax, pleural empyema, neoplastic pleural effusion and post-traumatic/post- surgical hemothorax/pneumothorax (e.g . in thoracic, heart or esophageal surgery), and in some types of heart surgery.
  • pneumothorax pleural empyema
  • neoplastic pleural effusion e.g . in thoracic, heart or esophageal surgery
  • post-traumatic/post- surgical hemothorax/pneumothorax e.g . in thoracic, heart or esophageal surgery
  • the technical problem set and solved by the present invention is that of providing a drainage device, particularly suitable for pleural drainage, but also suitable for cardiac drainage, allowing to overcome the drawbacks mentioned above with reference to the known art.
  • the present invention provides some relevant advantages.
  • the main advantage lies in the fact that the device of the invention allows an optimal management of the drainage procedure, allowing a monitoring and a complete control of the latter and concomitantly being extremely versatile and of simple structure.
  • the invention provides a drainage apparatus which lends itself to a modular embodiment, to the advantage of the overall inexpensiveness of the procedure.
  • Other advantages, features and operation steps of the present invention will be made evident in the following detailed description of some embodiments thereof, given by way of example and not for limitative purposes.
  • FIG. 1 showing a block diagram related to a preferred embodiment of the drainage device according to the present invention.
  • a drainage device particularly suitable for pleural drainage but also suitable for cardiac drainage, and obtained according to a preferred embodiment of the invention, is generally denoted by 1 .
  • the device 1 comprises a sealed collecting container 2, sealingly connected or connectible to a tubular drainage member 3.
  • a tubular drainage member 3 has, in use, an end introduced into the pleural cavity, or other intracorporeal space to be drained, of the patient (denoted by way of example with P in Figure 1 ), and the container 2 is just apt to receive the liquid and/or gaseous fluids drained by suction from said space by the tubular member 3 itself.
  • the container 2 is of disposable type and preferably made of plastics, e.g. by molding.
  • the container 2 is of the so-called "three- chamber” type.
  • the container 2 comprises three communicating environments, their arrangement being such that they are filled in sequence by the drained fluid.
  • the container 2 is transparent or has at least one transparent portion.
  • the container 2 has a liquid level sensor 4, apt to detect the level of drained liquid received into the container 2 itself.
  • the level sensor 4 is removably associated with the container 2.
  • the level sensor 4 is suitable for a reading in transparency of the level of liquid, without contacting the latter.
  • the level sensor can be removably held on the outer wall of the container, e.g. in a suitable housing thereof.
  • the three-environment embodiment of the container 2 entails the advantage, with respect to a single environment, of allowing a more accurate reading of the level of liquid.
  • the above-introduced level sensor may be replaced by an equivalent means for detecting the volume of liquid received into the container 2.
  • the drainage device 1 is intended as part of a drainage apparatus, the latter generally denoted by 100, comprising, besides the above-mentioned tubular member 3, also a control unit 5 in communication with the level sensor 4, and suction means 6.
  • the latter is controlled by the control unit 5 and is apt to cause a negative pressure in the container 2, and therefore in the tubular member 3, to obtain the desired removal of fluid from the pleural space or other intracorporeal space.
  • the apparatus 100 also comprises a pressure sensor 7, apt to detect the pressure inside the container 2 and it also in communication with the control unit 5.
  • the pressure sensor 7 is of probe type and therefore comprises a probe member 71 arranged within the container 2 and an actual sensor/transducer member arranged in correspondence of the control unit 5 or in communication with the latter.
  • the apparatus 100 further compri ses a flow sensor 8, it also in communication with the control unit 5 and arranged at a communication line 62 between the container 2 and the suction means 6.
  • the apparatus 100 also comprises ventilation means, in communication with the control unit 5 and apt to cause automatic ventilation of the container 2 in case of an excess of vacuum.
  • ventilation means comprises a ventilation valve 9 arranged in correspondence of the container 2 and an associated pressure sensor (preferably the same sensor 7 introduced above) apt to detect the pressure inside the container 2 itself.
  • the above-introduced suction means 6 is preferably implemented by a portable pump of suitable head.
  • the suction means 6 is preferably associated with adjustment means 1 1 , typically an electrovalve, to vary, in association with the control unit 5, the level of vacuum within a certain hysteresis range.
  • the suction means 6 may provide both an external power-supplying and a power-supplying by portable units, e.g. optionally rechargeable batteries.
  • the apparatus 100 may be equipped with a connection to the vacuum system usually present in hospitals, to be used alternatively to the above-introduced dedicated suction means.
  • means 12 for enabling/preventing fluid communication between the container 2 and the intracorporeal space to be drained typically implemented by a one-way safety valve.
  • This latter means 12 may be in communication with the control unit 5 and controlled thereby, and/or be associated with a vacuum detection sensor.
  • control unit 5 is suitable for managing the drainage procedure and may be implemented by hardware and software means known per se and based on digital technology.
  • the control unit 5 is of course interfaceable with suitable software installable on a PC or palmtop, by USB or wireless connection, or it can be directly incorporated in such systems.
  • control unit 5 also display means, e.g. a display, can be associated in order to immediately read, through said display, the values detected by the above-introduced sensors.
  • display means e.g. a display

I n fact, as mentioned hereto, according to a preferred embodiment the control unit 5 allows to select a hysteresis range of the suction means 6 (i.e., a variation range of the admissible vacuum level), which in particular can be set a priori or variable directly by the end operator. Such a selective setting allows also compensation, to the ends of the control of the procedure, for pressure variations related to respiratory acts of the individual patient.

  • control unit 5 by its own data processing means, is capable of monitoring and assessing the air leaks drained by the intracorporeal space, leaks that are preferably calculated by difference between the total volume detected by the flow sensor 1 1 and the volume of liquid as associated to the detection of the level sensor 4.
  • a difference greater than a certain predetermined threshold is an index of non-negligible air leaks, and therefore of the need to continue the drainage treatment.
  • the control unit 5 is capable of measuring and monitoring the level of pleural pressure as represented by the pressure into the container 2 detected by the pressure sensor 7, and of measuring and monitoring liquid pleural effusions by using the level sensor 4.
  • all sensors introduced hereto have at least one sensor portion not into contact with biological fluids and therefore reusable, both to reduce the costs of use and to have high-precision sensors available that may be equ ipped with self-controlling systems, not manageable in disposable systems.
  • the apparatus described lends itself to the use of sensors of commercial provenance, with no need of ad hoc design.
  • all sensors introduced hereto, and particularly the level sensor 4 are of electronic type. It will be understood that the device and the apparatus of the invention anyhow lend themselves also to the use of sensors, both disposable and non-disposable ones, according to the specific needs.
  • the above-described apparatus also comprises alarm means (e.g. of acoustic and/or visual type), activating when the values measured by one or more of the above-introduced sensors are out of a preset range (corresponding to values acceptable for the medical course).
  • alarm means e.g. of acoustic and/or visual type
  • the drainage device 1 formed by the container 2 and the level sensor 4 may be used separately, as part of known drainage systems (in this case also without level sensor 4), or associated with the sole suction means 6 and/or the control unit 5.
