DETAILED DESCRIPTION

(15) Various embodiments of the invention are discussed in detail below. While specific embodiments are discussed, specific terminology is employed for the sake of clarity. However, the invention is not intended to be limited to the specific terminology so selected and it should be understood that this is done for illustration purposes only. A person of ordinary skill in the art will recognize that other components and configurations can be used without parting from the spirit and scope of the invention. Each specific element includes all technical equivalents that operate in a similar manner to accomplish a similar purpose.

(16) FIG. 1 shows one embodiment of the abdominal massage apparatus on a patient 1 proposed in this invention. According to this embodiment, the apparatus consists of a single support plate 30 (which can be of any nature and more or less rigid) with which there are associated four adjacent and aligned massaging heads 56 (configured two by two), each integrated in a massage unit 10, and the massaging heads 56 are applied (when performing an abdominal massage) such that they are adjacent to each of the ascending section 21 and descending section 23 of the colon 20 of the patient 1.

(17) For performing the mentioned massage, each massaging head 56 applies a localized force or axial movement generating a pressure in a perpendicular, or normal, direction on the abdomen of the patient 1. Said massaging heads 56 can be driven by means of at least one fluid dynamic drive 81, for example, a pump, a piston or a pressurized fluid receptacle (see FIG. 4).

(18) The operation of the massaging heads 56 is controlled by control means 68 (FIG. 2) which allow regulating by means of different control buttons/elements 69 the time and/or the speed of activation of each massaging head 56, and/or the pressure that they apply on the patient 1, and/or the time during which they apply the mentioned pressure, etc.

(19) According to the embodiment of FIG. 1, the mentioned control means 68 control the massaging heads 56 (and as a result the massage units 10) by means of tubes/conduits 64 (for example, made of silicone or polyurethane) through which a fluid (aqueous fluid, air or another gas) passes, thereby allowing the operation of the massaging heads 56 for performing the abdominal massage. The mentioned tubes/conduits as seen in FIG. 1 are connected at one of their ends to the abdominal massage apparatus itself and include at the other end connectors 65 (male) that can be connected to the mentioned control means 68 (by means of respective female connectors 66). Alternatively, not illustrated in this case, the control means can be integrated in the abdominal massage apparatus itself. In this case, the control means comprise a control panel with control buttons integrated in the apparatus itself.

(20) FIG. 3 shows another embodiment of the abdominal massage apparatus proposed in this invention. According to this embodiment, the apparatus consists of two support plates 30, each having associated therewith two adjacent and aligned massaging heads 56, each integrated in a massage unit 10, and the massaging heads are applied (when performing the abdominal massage) such that they are adjacent to each of the ascending section 21 and descending section 23 of the colon 20 of the patient 1.

(21) In the embodiments shown in FIGS. 1 and 3, the massage units 10 integrating the massaging heads 56 are fixed with respect to the support plate or plates 30, i.e., they do no move, nevertheless, these massage units 10 can be driven individually and alternately in a synchronized manner as a result of the mentioned control means 68. The support plate or plates 30 are also attached to a belt 78, the latter comprising at least one band or tightening straps 79 going around the waist of the patient 1 when performing the abdominal massage (which straps can be fastened in the front like in FIG. 1 or in the back like in FIG. 3, particularly in the event that they incorporate massaging heads 56 envisaged for being adjacent to a transverse section of the colon 20 of the patient 1) and they allow correctly positioning the massaging heads 56 such that they are adjacent to the mentioned sections of the colon 20 of the patient 1.

(22) The massaging head 56 preferably comprises a flexible casing which is inflated or deflated by pumping of the mentioned fluid (aqueous fluid, air or another gas) until providing said force/pressure of controlled magnitude in a given time period. In a preferred embodiment, the flexible casing is formed by the association of several chambers which are superposed on, connected to and communicated with a central portion, forming a structure in the form of bellows. According to this preferred embodiment, said chambers can have an oblong shape (see FIG. 5 and embodiment of FIG. 3) or a cylindrical shape (embodiment of FIG. 1) and are oriented transverse to the course of the section of the colon 20 on which they are applied adjacent thereon.

(23) The inflating/deflating operations can be carried out by the mentioned fluid dynamic drive 81. Furthermore, inflating and deflating of the massaging heads 56 can be controlled, for example, with electrovalves 82 (for example, three-way electrovalves) connected to a programmable central server (not illustrated). Alternatively, inflating of the massaging heads 56 can be controlled, for example, by means of opening the electrovalves 82, allowing the fluid stored in each actuator to come out during the opening thereof, the actual pressure of the abdomen of the patient 1 being what forces the fluid to be discharged outward.

(24) The proposed abdominal massage apparatus can also include a power source, for example, batteries (not illustrated) for operating the different components of the apparatus. Nevertheless, the proposed abdominal massage apparatus can be powered by means of the direct connection thereof to the power supply.

(25) FIG. 6 shows another embodiment of the abdominal massage apparatus proposed in this invention. In this case, the apparatus comprises a support plate 30 on which there is arranged a set of massage units 10 formed by nine massage units (which have been schematically depicted and could be those illustrated in FIGS. 1 and/or 3), integrating the massaging heads 56 in the form of fluid driven actuators which, by means of a pressure of a fluid, inflate and deflate so as to allow performing the abdominal massage. In other words, this embodiment in relation to the embodiment of FIGS. 1 and/or 3 incorporates, in addition to an additional massaging head 56 in the support plate or plates 30 adjacent to the ascending section 21 and descending section 23 of the colon 20 of the patient 1 (i.e., three massaging heads 56 per ascending section 21 and descending section 23 of the colon 20), three other adjacent and aligned massaging heads 56, applied such that they are adjacent to the transverse section 22 of the colon 20 of the patient 1.

(26) In this case, the fluid dynamic drive 81 can collect the fluid from a central reservoir 85 (FIG. 7) and deliver same to a channel which is connected to the massaging heads 56. Two electrovalves 82 regulating the passage of the aqueous or gaseous fluid are arranged between the channel and each massaging head 56.

(27) The mentioned central reservoir 85 is preferably a flexible vessel made of a polymer film that can house the fluid needed so that the fluid driven actuators can operate. The central reservoir 85 can be manufactured with ultrasonically welded PU films.

(28) In addition, to convey the fluid from the central reservoir 85 towards the fluid driven actuators forming the massaging heads 56, i.e., to carry out the pumping system, a system for inflating using pressure by means of a series of membranes is used. Inflation is produced by the action of the fluid forced to perform inflation by means of the pumping system. This pumping system (for example, a hydraulic or pneumatic pump) is what applies pressure and transmits thrust force to said massaging heads 56.

(29) The abdominal massage apparatus proposed in this invention may comprise multiple massaging heads configurations (preferably in the form of fluid driven actuators). For example, according to another embodiment, in this case not illustrated for simplicity of the figures, the proposed abdominal massage apparatus in its simplest configuration comprises only two massaging heads (not limitative as a greater number of massaging heads are also possible) which are positioned on a single section the colon 20 of the patient 1, either the ascending 21, the transverse 22 or the descending 23 section, to perform the abdominal massage to the patient 1.

(30) Besides that, other embodiments (not illustrated either) of the proposed abdominal massage apparatus disclose a 33 configuration (three massaging heads 56 such that they are adjacent to at least two sections of the colon 20, e.g. the ascending section 21 and the descending section 23), a 222 configuration (two massaging heads 56 such that they are adjacent to each of the ascending section 21, transverse section 22 and descending section 23 of the colon 20), a 333 configuration (three massaging heads 56 such that they are adjacent to each of the sections 21, 22, 23 of the colon 20), a 44 configuration, etc. The fluid driven actuators are preferably independent from one another, as illustrated in FIGS. 1, 3 and/or 6, nevertheless, in other alternative embodiments (also not illustrated) these actuators can even form a continuous tubular element with inflating or deflating in sections.

(31) FIGS. 9, 10 and 11 show other possible embodiments of the abdominal massage apparatus proposed in this invention, showing the position of the support plate 30 facing the abdomen of the patient 1 in its working position. In this particular case, the examples illustrated in FIGS. 9 and 11 consist of a single massage unit 10, whereas the example of FIG. 10 comprises three massage units 10. In the three embodiments, said massage units 10 are associated with guide means 70 which allow guided movement of said massage units 10 along a path coinciding with the ascending section, transverse section and descending section of the colon of the patient 1 to whom the mentioned support plate 30 has been fixed, said movement being driven by translational means 50.

(32) By way of non-limiting example, the guide means 70 can consist of a C-shaped channel (see FIG. 12), or of one or two guide profiles 71 in the form of rails (see FIG. 13) on which the massage units 10 are anchored and slide. Said massage units 10 will preferably have bearings or wheels allowing them to slide on said guide means 70, and they will preferably have a coupling configuration preventing said massage unit 10 from separating from said guide means 70, without hindering the relative sliding thereof.

(33) The movement of the massage unit 10 along the guide means 70 will be driven by translational means 50, which, by way of example, can consist of an electric motor 51 connected by means of gears 52 to a rack arranged along the guide means 70 (FIG. 12), or to a belt 58 (FIG. 13), or to a threaded shaft arranged along the guide means 70 (not shown), or to a combination of the former or other known translation methods. It will be obvious to a person skilled in the art that many other embodiments are possible. The mentioned translational means 50 can be controlled and/or regulated by means of the mentioned control means, or other complementary means, in a manner coordinated with the control and/or regulation of the massaging heads 56.

(34) Therefore, the abdominal massage apparatus of FIGS. 9, 10 and 11 mainly comprises: a support plate 30 with which there is associated at least one massage unit 10; guide means 70, associated with said support plate 30, sized so that said at least one massage unit 10 is arranged superposed on the ascending section 21, transverse section 22 and descending section 23 of the colon 20 of the patient 1, for an abdominal massage; means 60 for moving said at least one massage unit 10 along said guide means 70 such that said massage unit 10 is arranged facing a treatment area including an abdominal wall of a patient 1; adjustable securing means 40 for adjustably securing the mentioned support plate 30 that go around the torso of the patient 1, positioning and maintaining the support plate 30 in said treatment area; a massaging head 56 integrated in said massage unit 10 for applying a pressure of controlled magnitude; and control means for controlling said movement of the massage unit 10 and said pressure of controlled magnitude.

(35) In this case, the massaging head 56 is driven by means of a mechanical drive (FIGS. 12 and 13), so according to a preferred embodiment, the massaging head 56 consists of a threaded or toothed vertical shaft connected to a motor which makes the vertical shaft move up and down. The simplest solution consists of using a threaded rod 80 as a shaft, whereas the motor makes the rod turn in order to move the pressure element up and down (in a non-limiting manner). For performing the movement with controlled pressure, the mechanical drive preferably has its own motor 54 integrated in the massage unit 10, such that it moves with the assembly.

(36) The device shown in FIG. 9 consists of inverted U-shaped guide means 70 made up of a single guide reproducing the path of the colon.

(37) In contrast, the example of FIG. 10 shows three independent straight sections which together form the guide means 70, one massage unit 10 being linked to each of said straight sections. In other words, a single massage unit 10 travels along each of the sections 21, 22, 23 of the colon 20 of the patient 1.

(38) In the third embodiment shown in FIG. 11, the parallel vertical guides G1 and G2 arranged at opposite ends of the support plate 30 serve as a vertical guide for a transverse guide Gt bearing a massage unit 10. The transverse guide Gt can move vertically along the vertical guides G1 and G2, and the massage unit 10 can move transversely along the transverse guide Gt. The assembly of vertical guides G1 and G2 and transverse guide Gt forms the guide means 70 and they allow the massage unit 10 to move following the path of the colon 20 of the patient 1.

(39) The translational movement and motion of the massage unit 10 is produced by the translational means 50, which can consist, for example, of a rack-type system or a toothed rail (FIG. 12) arranged along the guide means 70 and on which gears 52 driven by means of a motor 51 engage. In another alternative embodiment shown in FIG. 13, a belt 58, which can be a cogged belt, runs parallel to the guide means 70, the massage unit 10 being attached to said belt 58, which is driven by means of a motor (not shown) fixed to the support plate 30, causing the dragging of the massage unit 10. In another alternative embodiment, the belt 58 is fixed by its ends and the drive motor is mounted on the massage unit 10.

(40) The inclusion of several conducting guides 57 for carrying data and electricity to the massage unit 10 is also envisaged.

(41) For the correct operation of the abdominal massage apparatus in any of the described embodiments, the apparatus will have data storage and processing units that provide flexibility for reproducing several types of massages, i.e. different massage sequence patterns. The massage patterns are codified as a combination of force evolution during time, actuator unit activation sequence and duration and frequency of actuation for each actuator. The combination of these parameters allows to perform the mentioned types of massage such as: a pressure wave translating along the trajectory of the colon 20, a pressure turbulence pattern, a pressure gradient along the ascending 21 and descending 23 sections of the colon 20 with its maximum in the transverse section 22 of the colon or a pressure decreasing gradient along the trajectory of the colon 20 among other possible patterns. The different types of massages to be given to the patient 1 can be stored in an internal memory of the control means 68 (or alternatively in a memory external thereto, for example, stored in the Cloud) and be loaded by means of applying control software including a series of code instructions for performing the abdominal massage.

(42) The abdominal massage apparatus is able to reproduce manual massages given by professionals for treating the symptoms of constipation. The apparatus can store different types of massages from among which the patient 1 or another user may select the massage he/she wishes to receive, for example, by means of the mentioned control buttons 69 of the control means 68. Alternatively, the massage may be selected by means of using an independent smart computing device such as a smartphone, a tablet or a computer connected to the abdominal massage apparatus. In yet another alternative, the massage may be selected by means of a control panel integrated in the apparatus itself.

(43) Massages can be loaded into the apparatus by the patient 1 him/herself or by a medical professional responsible for supervising the procedure through the control means (in any one of the alternatives thereof) or alternatively by means of using a smart computing device. The different types of massages are preferably stored in file format. To prepare these files, data from manual massages performed by healthcare professionals can be captured. The data obtained from massages is subsequently analyzed and processed for optimal storage and use by the software application of the apparatus.

(44) The generated files contain the information needed for the apparatus to reliably reproduce the manual massage. Some of the stored parameters are: pressure applied over time in different areas of sections 21, 22, 23 where the massage will be given, location and movement of pressure/pressures over time, etc.

(45) The massage will be adjustable, offering different options for regulating duration, speed/frequency and intensity/magnitude. Intensity/magnitude of the massage is understood as the range of controlled pressures applied, which can comprise pressures ranging from 0.01 to 1 kg/cm2 and at most limited to 4 kg/cm2. Typical frequency of operation is planned to be between 0.1-0.9 cycles per second, not limitative, as broader range of frequencies, e.g. 0.05-50 cycles per second, in order to enable variable treatment patterns during the treatment session may equally be delivered.

(46) Furthermore, and for the purpose of preventing injury to the patient 1, the apparatus can have pressure sensors (for example, force-sensing resistorFSR-, pressure cells or piezoelectric sensors) monitoring at all times the pressure applied on the patient 1. The information picked up by the pressure sensors can be used to regulate the intensity of the massage together with the parameters entered by the patient 1 or another user. If the pressure sensors report a value exceeding the safety limits allowed by the apparatus, said apparatus can emit, in one embodiment, an alarm sound. Likewise, if the pressure limit is exceeded for a time period of more than 5 seconds, the apparatus stops the massage and returns to a rest state.

(47) The apparatus can capture and store data from massage sessions performed and store it in the data unit of the control means 68 or alternatively of a smart computing device. The apparatus can even send the captured and stored data to an external device or server through cable communication or by means of a wireless connection. Preferably, the information captured by the apparatus is: an identifier of the massage performed, the patient receiving the massage, duration of the session, a 3D map of pressures applied during the massage, mean pressure of the areas of maximum pressure and times of operation of the apparatus, among others. This information will allow a healthcare professional to monitor the progress and compliance of the patient 1 with the prescribed treatment, and even to make necessary adjustments to said treatment depending on the information received. Professionals may furthermore remotely configure the apparatus for the comfort of the patient 1 and agility of the follow-up process.
