Definitions

  • the device consists of two main elements, one of which generates the suction pressure and a plurality of specialized suction heads, which solely attach to the suction generating device depending on the skin condition and serve to remove tallow-like material or bacterial pus from the pores with the aid of suction pressure.
  • Physicians warn from pressing blackheads or infected pimples using the fingers, since the tallow material or bacterial pus will be pressed further against the pore cells and thus will contribute to a severe infection possibly resulting in scarring. They recommend treatment by a skin care professional, who generally open the pore using a sterile needle, empty the content using pressure from the rim and finally treat the pimple with an antibiotic cream.
  • the tool is designed to remove non-infected pimples and blackheads.
  • the device is placed with a ring like structure around the blackhead and pressed against the skin while the device is turned around a small angle.
  • the necessary pressure is generated in the open center, which expels the blackhead.
  • This procedure is sometimes also applied during a professional skin cleaning treatment, however it has the disadvantage that the pressure is significantly elevated inside the pimple during the treatment thus again posing the danger of an infection.
  • Another disadvantage is that the extractor only works when the skin has a firm support, e.g. over bone or muscle tissue.
  • An electrically powered skin cleaning device, called the “Panasonic Pore Cleaner” works exclusively by suction pressure. This device allows cleaning the pores of so called “oily skin", however is not suited to treat clogged pores or inflamed pimples.
  • a similar solution to the one proposed is protected by the patent GB2216805A.
  • a syringe like system comprising a ring like contact area and a piston, which has a needle like pin attached is first pressed against the skin and used to pry open a pimple. After this, the piston is manually retracted to crate a suction pressure above the pimple.
  • This device has many disadvantages. The opening of the pimple and the following application of suction happen without visual control, the separation of the device from the skin happens with a partial vacuum still applied, the application requires two hands, one of which not only has to hold the device steadily against he skin and at the same time provides the counterbalance for the piston force, the pus from the pimple contaminates the device and the needle is a permanently attached.
  • Fig.l A suggestion for a hand held vacuum device is depicted in Fig.l.
  • the device comprises an element (1), of which one end has a large diameter borehole to form a hollow cylinder and the other end has two smaller holes, one of which providing a guide for the piston shaft (2) and the other (8) to enable the suction head to communicate pressure with the suction generating device.
  • the suction heads Fig. 2,3 and 4 attach to the conical suction port (7).
  • a suction pressure arises in the suction heads when the user presses the piston comprising a shaft (2), spring support (3), membrane seal (4) and push button (5) such that the tension spring (6) expands.
  • the suction pressure is a result of the volumetric change on the suction side of the membrane seal (4) when the piston is pressed.
  • the device is handled by griping the element (1) with the hand such that the index finger has a hold against the suction port (7) opposite from the pushbutton (5). Now the thumb presses against the pushbutton and moves the piston in the earlier described way, simultaneously generating the suction pressure and tensioning the spring.
  • the spring When the pressure on the pushbutton is reduced, the spring will retract and move the piston to the original position, reducing the suction pressure to the original level of the surroundings. This allows handling the device using a single hand, hardly possible when one has to pull on the piston. Additionally, the separation of the suction heads and the suction device allows a flexible positioning of the suction head with respect to the skin, and furthermore prevents contamination of the suction device which contributes largely to a hygienic system. The separation in two parts also ensures the ambidextrous usability of the device.
  • the suction heads Figs. 2, 3 and 4 all have the same fundamental features.
  • a straight or angled pipe ((24), (34), (44)), having a conical connector ((27), (37), (47)), used to attach the suction heads to the suction device.
  • the conical connector is advantageous since.it ensures an airtight seal independent on the orientation of the suction head.
  • the conduit ((28), (38), (48)) provides means for communicating the pressure between the vacuum generating device and the suction head. The end of the conduit closer to the suction head provides space for a filter ((29), (39),
  • suction heads comprise a suction chamber, which has an opening to contact the skin along a ring like surface ((23), (33), (43)).
  • the suction chamber seals towards the surrounding pressure using the mentioned surface.
  • an optical window ((22), (32), (42)). This window allows the user to visually follow the procedure.
  • This window can be designed as a flat or as a thin lens, where the application area would be magnified.
  • the suction head Fig. 2 serves the treatment of closed and/or infected skin pores.
  • a removable or permanently installed needle is attached to the window.
  • the skin will be lifted into the suction chamber by the suction pressure until the closed and/or infected pore becomes perforated by the needle.
  • the pore material will discharge into the low-pressure region of the suction chamber.
  • the permanently installed or replaceable needle has a step designed to limit the maximum penetration depth to the epidermis. Thus the design assures a certain safety towards layperson use.
  • the replaceable needles will come with the system in sterile packaging and will be placed into the fixture for single use application. After the installation, the packaging will be removed such that the needle will remain sterile until the application.
  • this mechanism fails to open the pimple or infected pustule, it must be opened prior to the application using an external sterile needle. This, however, requires a special application procedures and is therefore not part of this invention.
  • a special clamp aids in the removal of the replaceable needle after the application, preventing accidental harm and infection to e.g. fingers.
  • the suction head Fig. 3 is designed for the treatment of open non-infected pores, so called blackheads.
  • the skin side opening (33) is considerably smaller than for the suction head Fig. 2 and the spherical shape of the head allows not only treating more difficult to reach places, but also to generate pressure on the blackhead by pressing the rim against the skin similar to a comedone extractor.
  • the advantage of this invention over the comedone extractor is that the whole procedure happens at a much lower pressure level.
  • the pressure levels between the cell wall and the blackhead material counteract a possible contamination of the skin cells.
  • the skin deforms into the suction chamber in a similar way as described earlier, locally stretching the pore open and supporting the clearing of the blackhead material.
  • the suction head Fig. 4 is designed for general skin cleaning.
  • the skin contact ring (43) has a fairly wide opening and a precisely rounded edge. Moving the suction head over the skin in slow motion, the skin deforms in a similar fashion as previously described due to the suction pressure and the pores stretch open especially in the vicinity of the rim. The local pressure difference close to the rim thus expels the pore content.
  • General area pore deep skin cleaning without contamination of the skin cells thus is possible.
  • the application can be done with or without prior application of skin cleaning lotions.
  • the visual control of the procedure also allows the user to see if there are already encapsulated pores which resist this skin cleaning treatment and which need further attention.
  • every suction head can be removed from the skin by reducing the suction pressure upon releasing the pressure on the piston actuator.
  • relief valves ((25), (35), (45)) will be incorporated for safety reasons. These valves will prevent the suction pressure to fall below a safe value to not destroy the blood capillaries. All parts of the invention can be made for single use and for repeated use.
  • the modular approach also allows producing only the suction heads for single use. Since the suction heads will become contaminated with the pore material during their use, they need to be either discarded after single use or sterilized for repeated use. The materials need to be chosen accordingly.

Abstract

Cette invention concerne un dispositif permettant de retirer une matière de type suif ainsi que du pus infecté des pores de la peau par aspiration. Ce dispositif comprend deux parties : une première partie permanente (1) servant à générer une aspiration, et une seconde partie échangeable, servant de tête de traitement et comprenant une fenêtre optique. Différentes têtes de traitement peuvent être fixées au dispositif (1) à génération d'aspiration en fonction de l'état de la peau à traiter. Les différentes têtes de traitement comportent l'ensemble des éléments fondamentaux suivants : une enveloppe, pourvue d'une ouverture (23, 33, 43) devant être appliquée contre la peau ; un orifice, permettant de fixer le dispositif (1) de génération d'aspiration ; ainsi qu'une fenêtre d'observation optique (22, 32, 42), pouvant être plane ou de la forme d'une lentille. Si une couche de peau obstrue le pore, ce dernier est ouvert au moyen d'une aiguille fixe intégrée vers laquelle la peau est attirée sous l'effet de l'aspiration, et au moyen de laquelle la couche de peau est finalement percée.
