Description

AUXILIARY DEVICE FOR THE HANDLING OF CARPULE TYPE SYRINGES DURING THE DENTAL ANESTHESIA PROCEDURE DESCRIPTION OBJECT OF THE INVENTION The present invention relates to an auxiliary device for the handling of Carpule syringes during the dental anesthesia procedure, in which the accidents are very common, especially after anesthetizing the patient and replacing the plug in the needle, before, during the procedure with the patient and at the end of it for its disposal. Sharps injuries are a frequent cause of infection transmission. 50% of the workers involved with the use of needles in patients remember at least one such injury in the previous year. Pitting occurs mainly due to improper handling of such objects after use as when the needles are recapped. This is a very dangerous event considered a very high labor risk that can spread serious infections such as hepatitis B or HIV. There is currently no device that allows the dentist to manipulate the Carpule syringe and its corresponding needle with one hand to eliminate the occupational risk of a picket with it.

BACKGROUND Currently, there is no device or instrument that allows the dentist during the procedure of anesthesia in their patients, manipulate the carpule syringe and its corresponding needle with one hand to eliminate the occupational risk of a picket with it. Occupational injuries caused by pickets with a patient's needle continue to be a significant and constant cause of exposure to serious and fatal illnesses in healthcare workers. In the case of dentistry, there is currently no device for the removal and repositioning of earplugs for syringe needles prior Carpule, during and after the procedure of infiltration of anesthesia to patients, which allows placing the anesthetic without risk of puncture and that protects the hands of the professional prior to the infiltration in the patient and later to replace the plug without danger of having an accident and acquire some contagion. Therefore, health workers who use needles or may be exposed to them are more prone to the risk of puncture injuries. These types of injuries can cause serious or fatal infections of pathogens contained in the blood such as the hepatitis B virus, hepatitis C or the human immunodeficiency virus (HIV;). '[' Piras diseases transmitted by needle sticks include syphilis, malaria and herpes. : In the present there are devices such as US6719736B2, WO2006 / 008086A1, US5336200A, among others which were created for the same need but both hands must be used during the anesthesia procedure and patient management, which unlike the device presented It has the following characteristics: s a fixed device that allows to use only one hand in the different stages of the anesthesia procedure, when placing the carpule syringe, when removing the cap to anesthetize the patient, when placing the cap after anesthetizing the patient, in case of needing to reinforce the procedure of anesthesia in the patient when removing and / or replacing the cap on the needle, at the end of the anesthesia procedure and placing the cap for the last time and discarding the needle in the container of the device, which facilitates its collection for elimination as RPBI (Biological Infectious Dangerous Residue). At the same time, the possibility of a needle picketing and a contagion of diseases transmitted by the use of blood by using only one hand and allowing the practitioner to have the other hand free to manage the tissues of the adult patient and the tissue management and behavior of the pediatric patient. One of the important recommendations is to avoid recapping needles, which in dentistry is not always possible since it is required to re-anesthetize the patient very often, using the same anesthesia cartridge and the same needle during the procedure and this It increases the risk of the accident, therefore the device that is presented allows to remove, and / or reposition the plug in the needle as many times as necessary eliminating the risk that this implies.

So also not only the dentist is at risk in every patient who anesthetizes, because if by accident, the dentist is punctured and did not change the needle, upon re-infiltrating his patient, he would also be exposed to have some contagion. This device is designed to eliminate the possibility of contagion for the patient because its ergonomic design gives the professional freedom of movement during the surgical procedure and facilitates the disinfection of it.

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an auxiliary device for the handling of Carpule-type syringes during the dental anesthesia procedure as seen in Figure 1, which comprises a rectangular plate (1), a support arm (2), a mechanism for fastening (3), an ejection mechanism (4), a container (5) and a cover (6).

Figure 2 shows a rectangular plate (1) in the lower part of the device, which is attached to the cover (6) and on the side that are joined has a groove (7) and a countersink (8), which is preferably of metal or some plastic polymer with enough weight to prevent the movement of the device.

Figure 3 shows a metallic support arm (2), which holds the syringe for; anesthesia and that is attached at one end to the cover (6) by means of a cylindrical piece :: (9) which can be a metal bar or a screw, etc. Also in the lower part of the arm has a pair of perpendicular plates (10) that join by means of a bar or screw: (11) etc., which joins another cylindrical or cubic bar (12) that supports the support arm by a slot in the cover (32) on which it rests.

Figure 4 (a, b, c and d) shows a clamping mechanism (3) with metal bristles in conical shape interlocked with each other (13) and covered on the outside by a spring (14) attached to the cover by the end of larger diameter that allows to return to the position initial and in the inner part presents at least two and up to eight structures found cubic (15) that prevent rotation and favor the clamping of the needle cap.

Figure 5 (a, b, c, d, e and f) shows an ejection mechanism (4) with a circular rotating metal plate (16) attached to the cover (6) through a screw (17) at the center and having a metallic button (18) that is activated when rotating it and locating it in the groove of the holder (19) which at the same time rotates a stop piece (20) in a perpendicular manner which stops the needle when placing the syringe and prevent its expulsion, in such a way that when pressing the metallic button (18) the needle contained in the container (5) is ejected. In addition, the metal button (18) in its internal part contains a cylindrical bar (21) with a groove (22) in its diameter to half its length and two metal springs (23) placed on the sides of the cylindrical bar (21). ).; Figure 6 (a, b and c) shows the metallic container (5) characterized by one; rectangular base (24) and four walls or faces which are perpendicular to the base, rectangular side and front (25), the rear is concave (26) on the inside. At the base, on its external part, it presents a half sphere (27) preferably in: the central part.

Figure 7 shows a cover (6) preferably made of metal, with an iplana front face (28) with a slight inclination and the convex rest (29). On the front face (28) has a circular slot for the clamping mechanism (30) located preferably from the center upwards centered and slightly towards the top, another slot for the torillilló (31) of the ejection mechanism plate ( 4) slightly, above the first and smallest. It also has a curved slot (33) through which the stop piece (20) of the plate that prevents ejection of the needle is moved. Also below the slot for the mechanism fastening (30) has a vertical groove (32) of the same size as the bar that holds the arm. In the rear part, the space for the container (5) is located, which must be wide enough to allow the functioning of the clamping mechanism (3).

Figure 8 shows the procedure of use with the device in inactive form, the needle and its anesthesia cap are placed within the holding mechanism (3) of the device, introducing it by the active side (the one used in the patient) without remove the colored cap (figure 8a).

Then the cap is removed from the inactive side and the Carpule type syringe is placed or inserted, which previously had the anesthesia cartridge in place, turning clockwise (clockwise) and activating the device arm to hold the syringe (Figures 8b, 8c and 8d).
