Abstract
Riešenie sa týká ručného hadicového mikrodávkovača s trojdobým nasáváním do výmennej trubičky na dávkovanie kvapalín, například krvi, ejakulátu a podobné, ktorého podstatou je, že pod funkčnou hadicou je kyvné na čapě usporiadaná tlačka, opatřená v spodnej časti kladkou, ktorá je v kinematickom zábere s podávačom ovládaným spúšťou, ktorého trojdobé nasávanie zabezpečuje aretačné zariadenie.The solution relates to a handheld micro-dispenser with three-stroke intake liquid dispensing tubes such as blood, ejaculate, and the like the essence is that under a functional hose is swinging on a pin arranged pin, provided at the bottom of the pulley that is in kinematic shot with the feeder controlled trigger, whose three-stroke suction secures the locking device.
Description
Vynález rieši zariadenie pre dávkovanie tekutin sposobom, ktorý obmedzuje poškodzovanie častíc v tekutinách, například biologických ako sú krv, ejakulát a podobné, a slúži pre účely jednorázových aplikácii.The invention provides a device for dispensing fluids in a manner that limits damage to particles in fluids, such as biologicals, such as blood, ejaculate, and the like, and is for single use purposes.
Doteraz sa pre mikrodávkovanie používajú obvykle zariadenia vybavené piestovými mechanizmami, čo sposobuje poškodzovanie objektov, například v biologických tekutinách a pri aplikácii zostáva zbytok aplikovanej dávky vo vyústění zo zariadenia.Until now, devices equipped with piston mechanisms are usually used for micro-dosing, causing damage to objects, for example in biological fluids, and when applied, the remainder of the applied dose remains in the mouth of the device.
Vyššie uvedené nedostatky sa odstránia tak, že tekutina je aplikovaná zariadením podl'a vynálezu. Jeho princípom je hadicový mikrodávkovač s trojdobým nasáváním do výmennej trubičky, čo zaručuje odstránenie predošlých nedostatkov a tiež sterilitu aplikácie a vhodnú volbu trubičky, podl'a objektu, do ktorého sa aplikácia prevádza.The above drawbacks are overcome by applying the fluid to the device of the invention. Its principle is a tubular micro-dispenser with three-time suction into the replaceable tube, which ensures the elimination of the previous shortcomings and also the sterility of the application and the appropriate choice of the tube according to the object to which the application is transferred.
Na pripojenom výkrese je příklad technického riešenia podlá vynálezu v podielnom řeze. Na výkrese je teleso 1 vo tvare pištole, z ktorého vyúsťuje výměnná trubička 10, prechádzajúca cez utesňovaciu skrutku 21 a v tesniacom krúžku 20 je spojená s hadicou 18, ktorá je uzatvorená zátkou 17. V telese 1 je pevne uložený čap 14, na ňom točné uložená tlačka 3 a čap 15, na ktorom je točné uložená spúšť 2, vybavená podávačomi 4 s nastavovacou skrutkou 6 a aretačnou vložkou 5, o ktorú sa opiera aretačné rameno 7 točné uložené na čapě 16, ktorý je tiež pevne uložený v telese 1.The attached drawing shows an example of a technical solution according to the invention in sectional view. In the drawing, the body 1 is in the form of a pistol, from which the replaceable tube 10 passes through the sealing screw 21 and in the sealing ring 20 is connected to a hose 18, which is closed by a plug 17. a press 3 and a pin 15, on which the trigger 2 is mounted, equipped with a feeder 4 with an adjusting screw 6 and a locking insert 5 on which the locking arm 7 is supported rotatably mounted on the pin 16, which is also fixed in the body 1.
V telese 1 sú aj skrutky 12, 13 uložené skrutkovatelne z vonkajšej časti telesa 1 tak, ako aj ovládatelnost v telese 1 uloženej poistky 8, v ktorej je ukotvená pružina 10 opierajúca sa o teleso 1. Skrutková pružina 9 sa opiera o spúšť a druhým koncom o teleso 1. Pružina 11 je oipretá o teleso 1 a druhým koncom tlačí na aretačné rameno 7.In the body 1, the screws 12, 13 are also screwed down from the outside of the body 1, as well as the controllability in the body 1 of the retained fuse 8, in which the spring 10 is anchored against the body 1. The spring 9 rests on the trigger and the other end The spring 11 is supported by the body 1 and presses against the locking arm 7 with the other end.
Zariadenie sa ovládá tlakom na spúšť 2, ktorá sa vsúva do telesa 1, pričom o podávač 4 opretá tlačka 3 uvolňuje stlačenú hadicu 18, ktorej vnútorný objem sa tým zváčšuje a tak nasáva. Spolu so spúšťou 2 sa posúva aj aretačná vložka 5, o ktorú pružina pritláča aretačné rameno 7, ktoré počas jedného úplného stlačenia spúšte 2 dvakrát zapadá do drážok aretačnej vložky 5, čo sposobí okamžitú změnu potřebného tlaku prsta na spúšť 2 a tak umožňuje trojdobé nasávanie.The device is controlled by pressure on the trigger 2, which is inserted into the body 1, while the presser 3, supported on the feeder 4, releases the compressed hose 18, the inner volume of which thereby increases and so sucks. Along with the trigger 2, the locking insert 5 is also moved by which the spring presses the locking arm 7, which during one complete depression of the trigger 2 fits twice into the grooves of the locking insert 5, causing immediate change of the necessary finger pressure on the trigger 2.
Skrutkou 13 sa nastavuje žiadúci ipohyb tretej doby sania. Keď sa uvolňuje tlak na spúšť 2, táto je vysúvaná skrutkovou pružinou 9, pričom tlačka 3 opretá o podávač 4 stláča hadicu 18, ktorej vnútorný objem sa zmenšuje a prv nasaté médium sa tak vytláča. Nárazom spúšte 2 na nastavenú dorazová skrutku 12 sa pohyb spúšte 2 zastaví. Úplným stlačením spúšte 2 přitom pootočením poistky 8 a opáť uvolněním spúšte 2 sa jeho čelná hrana oprie o poistku 8 skrutková pružina 9 přitlačí čelnú hranu spúšte 2 o poistku 8, čím sa zabráni vysunutiu spúšte 2 z telesa 1.Screw 13 adjusts the desired movement of the third suction time. When the pressure on the trigger 2 is released, it is extended by a helical spring 9, whereby the press 3 leaning against the feeder 4 compresses the hose 18, the inner volume of which is reduced and the first sucked-in medium is displaced. Impact of the trigger 2 on the set stop screw 12 stops the movement of the trigger 2. By fully depressing the trigger 2, by rotating the fuse 8 and again releasing the trigger 2, its front edge abuts against the fuse 8 a screw spring 9 presses the front edge of the trigger 2 against the fuse 8, thereby preventing the trigger 2 from sliding out of the body 1.
Opátovným stlačením spúšte 2 pružina 10 vrátí poistku 8 a umožní vysunutie spúšte 2 z telesa 1. Nastavovacou skrutkou 6 sa mění sklon podávača 4 a tým zdvih tlačkyBy pressing the trigger 2 again, the spring 10 returns the fuse 8 and allows the trigger 2 to be pulled out of the body 1. Adjustment screw 6 alters the inclination of the feeder 4 and thus the stroke of the print.
3. Zariadenie sa s výhodou dá používat pri inseminácii. Funkcia podlá příkladu technického riešenia a příkladu navrhovaného využitia potom spočívá v tom, že tlakom na spúšť 2 v prvej fáze je nasávaný cez aplikačnú trubičku vzduch.3. The device is preferably used for insemination. The function according to the example of the technical solution and the example of the proposed application then consists in that by the pressure on the trigger 2 in the first phase air is sucked through the application tube.
V druhej fáze sa nasáva médium určené pre aplikáciu. V tretej fáze sa opat nasáva vzduch, čím je uzavretý postup nasávania. Uvolněním spúšte 2 tlakom pružiny 9 na hornú časť spúšte 2 dochádza k jeho pohybu do východiskovej polohy a tým aj ku výtlaku. Vzduch v zadnej časti nasávacej trubičky 19 vytlačí posledně zbytky aplikovaného média, ktoré sa spravidla usadzovali na ústí nasávacej trubičky 19.In the second phase, the medium to be applied is aspirated. In the third phase, air is sucked in, which completes the suction process. By releasing the trigger 2 by pressing the spring 9 on the upper part of the trigger 2, it is moved to the starting position and thus also the displacement. The air at the rear of the suction tube 19 expels the remainder of the applied medium, which usually settles on the mouth of the suction tube 19.
