Description

FIELD OF THE INVENTION [001] The present invention relates to nasal aspiration devices for use in infants and children. FUNDAMENTALS OF THE INVENTION [002] A fairly common symptom in babies and children is nasal congestion. Generally, babies and children under 4 years of age are unable to blow their noses on their own, and may experience prolonged pain and discomfort due to secretions accumulating in the nasal tract. [003] The conventional process for treating this condition is done by nasal irrigation, applying nasal saline solution (or another suitable solution) to the baby's nose using a syringe. The saline solution is able to reduce the viscosity of the secretions to facilitate excretion. [004] After nasal irrigation, when the excretion of secretions is still not possible, or is insufficient, the secretions can be aspirated using a nasal aspirator. Nasal aspirators are devices consisting of a hose, a nasal tip to be positioned in the baby's nostril, a reservoir, and a mouthpiece to be placed in the mouth of a user (for example, one of the baby's parents). When positioning the nasal aspirator for use, the user suctions through the mouthpiece to remove nasal secretions from the baby by pressure. [005] Although nasal irrigation and nasal aspiration are indicated for the treatment of the same condition (nasal congestion), each process is dependent on different equipment, requiring users to have both devices at home, increasing the total costs for treatment, as well as increasing the use of raw materials and energy for manufacturing. BRIEF DESCRIPTION OF THE INVENTION [006] In order to overcome the shortcomings of the prior art, an adaptation set was developed to convert a conventional nasal lavage syringe into a nasal aspiration device, as defined in this document. [007] The developed adapter kit allows the nasal irrigation syringe to be reversibly converted into a nasal aspiration device, eliminating the need to purchase two different pieces of equipment. [008] The invention also relates to a convertible syringe comprising said adapter assembly. [009] The invention assembly is capable of being installed on a conventional nasal irrigation syringe by removing the syringe plunger, inserting one end of the connector into the syringe body, and inserting the hose into the other end of the connector. [010] Another relevant feature of the present invention is that it has been developed in such a way as to guarantee the retention of the secretion extracted from the baby's nose, keeping it in the body of the reservoir and preventing its passage into the hose and subsequent contact with the user's mouth. [011] This detail represents an advance, as it achieves the desired result (secretion retention) without the need for filters. This result is achieved exclusively due to the shape of the assembly, whereby the fit and arrangement of the parts cause the secretion to be retained. BRIEF DESCRIPTION OF THE FIGURES [012] Fig. 1 shows a perspective view of the assembly connector according to a preferred embodiment of the invention; [013] Fig. 2 shows a bottom view of the connector shown in Fig. 1; [014] Fig. 3 shows a top view of the connector shown in Fig. 1; [015] Fig. 4 shows the adapter set comprising the connector shown in Fig. 1, installed on the body of a conventional syringe. DETAILED DESCRIPTION OF THE INVENTION [016] The invention will be described in greater detail below, with regard to the attached figures. [017] It will be readily understood by those skilled in the art that various alterations may be made to the described characteristics without departing from the scope of the patent, as defined by the appended claims. [018] In one embodiment of the invention, the adapter assembly (100) comprises a connector (110); a hose (120); and a nozzle (130), and said connector (110) comprises a body (111); a hose fitting portion (112); a syringe fitting portion (113); and a stop surface (114). [019] A user, when using the assembly (100) of the present invention, is able to convert a conventional syringe, preferably a nasal irrigation syringe (200), into a nasal aspirator. To do so, the user removes the plunger from the syringe, and inserts the assembly of the present invention by means of the connector. [020] With the assembly (100) connected to the syringe (200), the user is able to perform the conventional method of using a nasal aspirator, inserting the end of the syringe body (210) into the baby's nostril, while the mouthpiece (130) is placed in the user's mouth to perform the aspiration. [021] During aspiration, the unique shape of the connector allows the maneuver to be performed in complete safety, as it prevents the passage of extracted secretion into the hose, since regardless of the use of a filter, the cavity (116) formed in the inner part of the connector (110) acts as a reservoir in which the aspirated secretions are retained. [022] The syringe body (210) can operate as a reservoir similar to conventional na
