Definitions

  • the invention relates to a device for producing in particular reproducible medical foam or bubble suspension from a gaseous and a liquid medium.
  • the invention relates to a mixing device for the reproducible preparation and administration of injectables - such as e.g. Sclerosing agents, diagnostics, therapeutics, homeopathic remedies and autologous blood.
  • Sclerotherapy is the planed elimination of intra-, subcutaneous and / or transfascial varices and the sclerotherapy of subfascial vessels in venous malformations by injecting a sclerosing agent.
  • the various sclerosing agents cause damage to the endothelium of the vessels. This is followed by a secondary vascular occlusion and, in the longer term, the transformation of the veins into a connective tissue strand, to sclerosis.
  • the aim of the sclerotherapy is the definitive transformation into a fibrous strand. This can not recanalize and corresponds in its functional result to the surgical procedure for the removal of a varix.
  • the sclerotherapy with foamed sclerosants is becoming increasingly important.
  • the foam stays longer in the vein.
  • surface-active sclerosing agents such as polidocanol
  • polidocanol are usually brought into a foam-like state by reciprocating between two syringes or by shaking and then conventionally injected.
  • a mixing device for producing medical foam or for producing bubbles is known from EP 0 564 505.
  • a mixer with a helical mixing element is an additional element that can be permanently connected to a syringe.
  • the medium passes into the mixer, which contains the gas in a defined volume and type,
  • gas phase and liquid phase along the helical mixing element are mixed. This can produce a therapeutic and / or diagnostic foam.
  • the mixing device described in EP 0 564 505 has the disadvantage that the mixer, which is firmly connected to the syringe, in particular when the solution is moved back and forth, can easily be broken off or tilted due to the long lever. Furthermore, the mixer is a component which, due to the spiral-shaped mixing elements arranged in the mixer, can only be produced as an injection-molded part using elaborate injection molds.
  • a dual chamber syringe connected to a static mixer capable of producing foam is disclosed in US-A-3767085.
  • the object of the invention is to provide a device with which medical foam can be generated from a gaseous and a liquid medium in a simple manner.
  • the device according to the invention has an active substance chamber and a gas chamber. Both chambers are closed with one piston each. Furthermore, the device has a foam generator, which in particular has one or more screens. Both the drug chamber and the gas chamber are connected directly or indirectly to the foam generator. According to the invention, the two pistons are arranged displaceably in the respective chamber. In particular, the two pistons are connected together or connectable during actuation of the device, so that the two pistons are displaced together in each case in one of the two chambers. This results in an increase in the pressure in the chambers and thus conveying or transporting the active substance and the gas in the direction of the foam generator or through the foam generator therethrough.
  • the device according to the invention is thus very easy to handle, as moved by a movement both pistons and thus both media are pressed or transported in the direction of the foam generator.
  • the emerging from the foam generator medical foam then only needs to be collected, but can also be applied directly.
  • a reciprocation of a gas and a liquid or a gas and a detergent between two syringes is not required.
  • the production of a standardized sterile foam is thus considerably easier.
  • the provision of a compressed gas container in the device according to the invention is not required.
  • the two pistons are connected to one another via a connecting element.
  • the connecting element is in this case preferably configured such that one of the two chambers is opened during displacement of the connecting element.
  • the connection of the two pistons takes place only by the actuation of the device.
  • the connecting element is particularly preferred in this case to form the connecting element as a conveying channel, for example as a hollow needle.
  • a driving element which may be formed in particular as a bead or plate. This makes it possible, when moving the connecting element in the direction of one of the two chambers closing the piston after the example piercing or opening of the piston to push it into the corresponding chamber and thus to increase the pressure in the chamber, so that the located in the chamber Preferably, medium flows into the hollow needle and through it to the foam generator.
  • one of the two pistons is in particular firmly connected to the foam generator. Furthermore, one of the two pistons may also be loosely connected to the foam generator.
  • the medium flows through the piston into the foam generator. Furthermore, it is preferred that the medium from the second chamber through this piston flowing.
  • the two media mix in this preferred embodiment, preferably in the foam generator and / or immediately before the foam generator. It is particularly preferred to push the medium from the chamber further away from the generation of foam through a delivery channel provided in the connecting element and at least partially supply it directly to the foam generator. In this embodiment, a mixing of the two media takes place directly in the foam generator. Possibly.
  • This mixing element may be provided in or in front of the foam generator, a mixing element in which a premixing of the two media takes place before they are pressed by the foam generator.
  • This mixing element may, for example, be a type of sponge or a sintered material which simultaneously serves to decelerate the active substance. As a result, the foam generation is improved.
  • foam generator within the syringe, for example in the batch, e.g. also forms the luer lock to provide.
  • a foam outlet opening of the foam generator can be connected to a foam collecting container.
  • the foam collecting container may be a conventional syringe, which may then be connected to the foam outlet opening, for example via a Luer lock.
  • the device according to the invention is suitable because of its simple and inexpensive construction of preferably individually manufacturable simple parts, especially for disposable use. In particular, due to the disposable use, the required sterility can be ensured. Another advantage of the device according to the invention is that the drug and the gas come into contact with each other only immediately before the application.
  • the device according to the invention for the production of medical foam has an active substance chamber 10 and a gas chamber 12.
  • the active substance chamber 10 is designed as a carpule 14 (FIG. 4) and is sealed with a first piston 16, which may be a rubber stopper or the like.
  • the carpule 14 is held in a holder 18, in which the carpule 14 in the direction of an arrow 20 in the holder 18 in the in Figs. 1 - 3 shown position is inserted.
  • the carpule 14 is in this case fixed by latching elements 22 and with respect to the latching elements 22 arranged stops 24 (FIG. 4) in the position.
  • the holder 18, which receives in the cylindrical opening 26, which preferably also circular cylindrical trained carpule 14 is connected to a cylindrical projection 28. Within the cylindrical projection 28, the gas chamber 12 is formed.
  • the gas chamber 12 is also sealed by a second piston 30.
  • the gas chamber can optionally also be designed as a carpule.
  • the likewise cylindrical gas chamber 12 has a larger diameter than the active substance chamber 10.
  • the provision of active ingredient or gas in the two chambers can also be reversed. This is particularly useful for drugs in which only a small amount of gas is required for foaming, ie in the case of active substances which are already readily foamable themselves.
  • the height of the gas chamber 12 and the active substance chamber 10 is substantially the same, wherein preferably the gas chamber 12 is slightly higher in order to be able to completely empty both chambers 10, 12 if the pistons 16, 30 are fully depressed.
  • the piston 30 is designed as a hollow needle connecting element 32 is connected.
  • the piston 30 has a suitable, for example, cylindrical projection 34 (FIG. 4) into which the hollow needle 32 can be inserted and held, for example, by adhesive bonding.
