Definitions

  • the invention relates in general to a medical device applying repetitive compressions to the body of a human helping him/her to loosen mucus from the lungs and trachea, and improve the blood circulation.
  • the present invention relates to high frequency chest wall oscillation (HFCWO) therapy systems, especially but not limited to HFCWO therapy systems suitable for use in home care as well as in a hospital, or in a healthcare facility.
  • HFCWO high frequency chest wall oscillation
  • Irregularities in the normal mucociliary transport system or hyper secretion of respiratory mucus results in an accumulation of mucus in the lungs causing severe medical complications such as hypoxemia, hypercapnia, chronic bronchitis and pneumonia.
  • Abnormal respiratory mucus clearance is a manifestation of many medical conditions such as pertussis, cystic fibrosis, atelectasis, bronchiectasis, cavitating lung disease, vitamin A deficiency, chronic obstructive pulmonary disease (COPD), asthma, and immotile cilia syndrome. Exposure to cigarette smoke, air pollutants and viral infections also affect mucociliary function negatively. Post surgical patients, paralyzed persons, and newborns with respiratory distress syndrome also exhibit reduced mucociliary transport.
  • Chest physiotherapy is a well-known method for treating patients with one or more of the above health conditions.
  • CPT Chest Physical Therapy

  • the document EP1932501 describes a HFCWO system that comprises an air pulse generator in communication with an inflatable garment.
  • the air pulse generator comprises housing and an air pulse assembly coupled to the housing.
  • the problem with this device is that the whole system is a big and heavy device, difficult for the patient to move around. Furthermore since this device is mainly used in hospitals and healthcare institutions, but also as home care, it would be an advantage to avoid the use of a clumsy, heavy and expensive system.
  • the purpose of the present invention is to propose a device and a method to solve the above problems found with HFCWO systems according to the prior art.
  • the present invention relates to a medical system for high frequency chest wall oscillation (HFCWO) treatments comprising
  • the mentioned medical system is a HFCWO system or device. Since many hospitals have a global air distribution system that provides steady stream air, the system according to the invention can be directly connected to the global air distribution system and thereby avoiding a big and heavy compressor with pulsed air. The invention can also be used with a compressor generating a steady stream of air.
  • the invention may comprise anyone of the following features.
  • the air supply is a pressured air distribution of a building and/or comprises means for storing pressured air under a liquid or gaseous state and/or comprises a compressor provided to deliver a stream of substantially steady air.

  • the outer part is provided with one or more holes to create air passages.
  • the valve comprises at least an input hole connected to the air system and at least an output hole connected to the wearable body.
  • the system is provided so that in a first position the inner part blocks at least one of an input hole, thereby preventing passage of air between the input and output hole; a second position, where the inner part lets the input and output hole unblocked, allowing air passage between them.
  • the outer part has a substantially cylindrical body and the inner part, which may be a piston configured to move inside said cylindrical body, said piston being connected to a motor.
  • the inner part can move with a translational movement and/or a rotational movement.
  • the motor may be a 12V DC motor or alternatively the motor can be replaced by a magnetic system, which will reduce the wear and tear and noise.
  • the valve is further configured to control the amount of pressured air let through to the wearable body by movements of the piston.
  • the valve is further configured to release the pressured air from the wearable body to the outside of said system by movements of the piston.
  • the valve is also configured to alternate between letting pressured air pass through the valve to the wearable body and releasing the pressured air from the wearable body to the outside of said system.
  • the partially resilient body adapted to be worn by a human patient can be but is not limited to, a vest or a jacket. It has at least two compartments configured to be independently filled with pressured air. Each of the compartments comprises a valve for controlling the frequency of the pressured air in that compartment. In another embodiment, each valve controlling the frequency of the pressured air in a compartment can be comprised within the jacket but located outside of said compartment. In a third embodiment, the same valve can be located outside the jacket.
  • Two distinct compartments can for example be the front side of the jacket and the back of the jacket.
  • the valve controls the volume of the pressured air in the corresponding compartment.
  • one valve can control the volume of the pressured air in more than one compartment at the time.
  • valves controlling the body compartments also referred to as local valves
  • the valve is configured to alternate between letting pressured air pass through the valve to a first compartment of the wearable body, letting pressured air pass through the valve to a second compartment of the wearable body and releasing the pressured air from the wearable body to the outside of said system.
  • the system further comprises a user interface allowing a user of the system to control the movements and frequency of the inner part in relation to the outer part.
  • a user interface allowing a user of the system to control the movements and frequency of the inner part in relation to the outer part.
  • the wearable body is a wearable device on the upper body of a human.
  • the wearable device is a vest or a jacket, and the system is a High Frequency Wall Chest Oscillation (HFWCO) therapy.
  • HFWCO High Frequency Wall Chest Oscillation
  • the invention further relates to a method of generating air pressure in a body, said body being at least partially resilient, comprising sending pressured air from an air supply into at least part of said partially resilient body Characterized in that
  • Figure 1 shows an air supply connected to a valve according to the invention.
  • the air supply could for example be a compressor providing compressed air.
  • the compressed air is continuously provided in a steady stream meaning with a constant flow and volume of air.
  • the valve connects the air supply to the jacket.
  • the valve is driven by a motor connected to a power supply.
  • the valve could also be driven by a magnetic system as described earlier.
  • the valve has several options for controlling the compressed air pushed into it. In the main two, the compressed air is either blocked by a closed valve stopping the flow into the jacket, or let through by an open valve, which will inflate the jacket connected thereto. Further options will be revealed to the reader later in this document.
  • the jacket in figure 1 is either fully made of a material that is flexible, or of a combination of resilient parts and rigid parts.
  • the jacket could for example have a rigid material for the exterior part of the jacket and a flexible material for the interior part. This last embodiment is preferred to orientate the press movements, resulting from inflating the jacket, towards the body of the patient who wears it.
  • Figure 2a and 2b shows the valve according to the invention in further details.
  • FIG 2a we see a drawing of the valve cylinder 1.
  • the cylinder 1 is hollow configured to receive a piston 5.
  • the piston is configured to perform a sliding movement along the longitudinal axis of the valve cylinder 1.
  • the cylinder 1 further comprises one or more holes 4 of equal or different sizes.
  • the holes 4 are preferably aligned in two rows, each row having the same number of holes and are substantially facing each other.
  • the cylinder 1 is preferably made of stainless steel or aluminum.
  • Figure 2b reveals the piston 5 configured to make translational movements along the shared longitudinal axis of the cylinder 1 and the piston 5.
  • the piston 5 is driven by a motor, an opening at one extremity is provided with internal threads to fasten the piston 5 to the mechanical countershaft of the motor (not shown in the figures).
  • the piston 5 is driven by other means that does not require a motor, and the piston 5 therefore has no opening in its extremity.
  • the piston 5 is preferably made of PEEK (Polyether ether ketone). PEEK is a material that enables a continuous lubrication while sliding inside the cylinder 1 to give the minimum level of friction.
  • the piston 5 could be described as having a body 6, a neck 7 and a head 8.
  • the body 6 and the head 8 of the piston 5 have the same diameter while the neck 7 has a diameter that is inferior to the diameter of the body 6 and head 8.
  • the piston 5 is preferably machined from one piece, what is also referred to as a mono-bloc.
  • piston neck 7 can also be provided longitudinally in relation to the piston as a piston groove or recess. In that case, the piston rotates clockwise and anticlockwise instead of up and down.
  • Figures 3a and 3b show the assembled valve 10 comprising the valve cylinder 1 and the piston 5.
  • a jacket 2 is connected to a first row of holes 4 provided in the valve cylinder 1.
  • the second row of holes 4 is mainly connected to the compressed air supply 3, however with one hole reserved for an outlet connected to the exterior when releasing the compressed air from the jacket 2.
  • the jacket 2 With the piston 5 moving forth and back between the two positions shown in figure 3a and 3b , the jacket 2 will be alternately inflated and deflated with a frequency depending on the motor connected to the piston 5 or the alternative driving mechanism used to activate the piston 5, for example a woofer.
  • This frequency can be set by the operator of the system as shown in figure 4 .
  • Figure 4 represents a generic flow chart of the system according to the invention.
  • one valve 10 can be replaced by several valves working cooperatively in series.
  • the valves can be identical but can also be different, for example, they could have a different number and different size of holes 4.
  • the pistons 5 can move synchronously or independent of each other.
  • the pistons 5 however move according to a predefined structure set by the operator of the system using the control panel.
  • one predefined program may consist of moving one or more pistons 5 randomly for a certain amount of time.
  • a main valve 10 is connected to several local valves as shown.
  • the main valve 10 being physically similar to the local valves, distribute the compressed air flowing in from the air supply 3, to these local valves either sequentially one by one or sequentially by groups.
  • the outlet of the main valve 10 connected to the outside as seen in figure 5 might not be used. Alternatively, it might be used as a main outlet connecting several local outlets from local valves.
  • each local valve can be connected to a specific compartment of the jacket 2, independent of and isolated from other compartments.
  • the jacket 2 has two compartments: one front compartment and one back compartment.
  • a separate valve 10 for each compartment it is possible to inflate the front of the jacket 2 independently of the back and vice versa. They could be inflated sequentially to create alternating but cooperative compressions. It also becomes possible to inflate only one compartment while keeping the other inactive. This allows a more controllable and focused treatment using the jacket 2.
  • compartments a jacket 2 there is no limit to the number of compartments a jacket 2 might possess. In fact, the more compartments a jacket 2 has, the more personalized and customizable the treatment will be.
  • each valve can be connected to a number of jacket compartments only limited by the number of holes 4 provided in the valve.
  • valves of the system as inlet valves, meaning that the valves control the air let in to the jacket.
  • the invention can be realized by controlling the pulsations with identical exit valves. This is done by letting a steady stream of pressured air into the vest and creating the pulses by decreasing the pressure when the valve is aligned to the outside and increasing the pressure when that outlet valve is closed and the internal vest pressure goes up again.
