Description
JERINGA MEZCLADORA MIXING SYRINGE
D E S C R I P C I Ó N OBJETO DE LA INVENCIÓN D E S C R I P C I O N OBJECT OF THE INVENTION
La presente invención pertenece al campo de los dispositivos para la introd ucción de agentes en el cuerpo vía su bcutánea , intravenosa o intramuscular, y más concretamente a jeringas. The present invention pertains to the field of devices for the introduction of agents into the body via its bcutaneous, intravenous or intramuscular, and more specifically syringes.
El objeto principal de la presente invención es una jeringa que asegura unas mayores condiciones higiénicas y sanitarias durante su manipulación, evitando todo posible contagio y transmisión de contaminantes en la parte interior del tubo, al no haber contacto exterior ninguno con el émbolo. The main object of the present invention is a syringe that ensures greater hygienic and sanitary conditions during handling, avoiding any possible contagion and transmission of contaminants in the inner part of the tube, since there is no external contact with the piston.
ANTECEDENTES DE LA INVENCIÓN BACKGROUND OF THE INVENTION
En la actualidad existe en el mercado una gran variedad de jeringas o jeringuillas según el sector y aplicación para los que se empleen, no obstante su manejo es común y similar en todos los campos. At present there is a wide variety of syringes or syringes on the market depending on the sector and application for which they are used, however their handling is common and similar in all fields.
Las jeringas tradicionales requieren por parte del usuario de una mayor o menor habilidad dependiendo del trabajo en el que vayan a utilizarse, puesto que el empleo de una jeringa para absorber una cantidad de medicamento, suero, etc., que no necesita ser mezclado no queda contaminado, sí aquel que requiere disolución para ser introducido al paciente, ya sea por vena, arteria, sonda vesical u otra vía aséptica. Traditional syringes require a greater or lesser skill on the part of the user depending on the work in which they are to be used, since the use of a syringe to absorb a quantity of medication, serum, etc., which does not need to be mixed does not remain contaminated, yes the one that requires dissolution to be introduced to the patient, either by vein, artery, bladder catheter or other aseptic route.
El problema técnico que aquí se plantea es que cuando el personal médico y sanitario emplea jeringas para realizar mezclas de medicamentos u otras soluciones, el émbolo que hay localizado en su parte central es irremediablemente contaminado al entrar en contacto con los dedos de las manos
del enfermero, a través de los cuales puede contagiarse de microorganismos. De esta manera, al extraer la mezcla final de medicamento con la jeringa, dicha mezcla es contaminada por la pared interior del tubo de la jeringa, que ha sido contaminada anteriormente por el émbolo al extraer el disolvente y éste luego introducirlo en la sustancia a disolver. The technical problem that arises here is that when medical and healthcare personnel use syringes to make mixtures of medications or other solutions, the piston that is located in its central part is hopelessly contaminated when it comes into contact with the fingers of the nurse, through which he can get microorganisms. Thus, when the final drug mixture is extracted with the syringe, said mixture is contaminated by the inner wall of the syringe tube, which has previously been contaminated by the plunger when the solvent is removed and then introduced into the substance to be dissolved. .
Las repercusiones negativas que esto puede tener sobre la salud y seguridad de los pacientes son muy importantes, ya que aumenta la posibilidad de producir flebitis, infecciones nosocomiales y, en caso de tratarse de pacientes inmunodeprimidos, también septicemias con probabilidad de muerte. The negative repercussions that this can have on the health and safety of patients are very important, since it increases the possibility of producing phlebitis, nosocomial infections and, in the case of immunosuppressed patients, also septicemias with probability of death.
