Abstract
Podstatou riešenia je pružná válcová plocha ukončená kolmým čelom, na ktorej vytvořený zářez leží v rovině rovnobežnej s myšlenou osou tejto valcovej ploohy. Velkost vytvořeného úseku na valcovej ploché a na kolmom čele je rovnaký ako vnútorný priemer valcovej plochy. Riešenie je možné využit pri meraní tepenného tlaku krvi nepriamou metódou s deformačným alebo kvapalinovým tlakomerom.The essence of the solution is a flexible cylindrical surface terminated by a perpendicular face, on which the formed notch lies in a plane parallel to the imaginary axis of this cylindrical surface. The size of the formed section on the cylindrical surface and on the perpendicular face is the same as the internal diameter of the cylindrical surface. The solution can be used in measuring arterial blood pressure by an indirect method with a deformation or liquid pressure gauge.
Description
Riešenie sa týká výtlačného pružného ventila například z gumy k prístrojom na meranie tepenného tlaku krvinepriamou metodou s použitím deformačného tlakoměre.The solution relates to a pressure elastic valve, for example of rubber, to devices for measuring arterial pressure by a blood pressure method using a strain gauge.
Doposial známe konštrukčné riešenia prístrojov pre meranie tepenného tlaku krvi nepriamou metodou využívajú ventily s pohyblivým dielom, alebo výtlačné gumové ventily rotačného tvaru, na ktorých je vpichom ostria nástroja do ich valcovej časti vytvořený zářez róznych tvarov, ktorého stopy neležia na priamke.So far, known designs of devices for measuring arterial blood pressure by indirect method utilize movable part valves, or rotary-shaped discharge rubber valves, on which a cutting edge of the tool is formed into the cylindrical portion of the tool, the traces of which do not lie on a straight line.
Nevýhodou známých riešení je technologicky náročná výroba ako aj možnost vzniku vydrolenín v zárezovej ploché.The disadvantage of the known solutions is the technologically demanding production as well as the possibility of scaling in the notch flat.
Uvedené nevýhody odstraňuje výtlačný pružný ventil na meranie tepenného tlaku krvi vytvořený z valcovej plochy opatrenej zárezom. Podstata riešenia spočívá v tom, že rovina zářezu na valcovej ploché ukončenej kolmým čelom je rovnoběžná s myšlenou osou valcovej plochy. Velkost takto vytvořeného úseku na valcovej ploché a na kolmom čele je rovnaká ako vnútorný priemer valcovej plochy. Výtlačným pružným ventilom sa zvýši spolahlivost pri opakovanom použití. Zářez so stopou v tvare priamky je snadno vyrobitelný, pričom sa pri jeho výrobě úplné vylúči možnosť vytvorenia vydrolenín, ktoré sú zdrojom netěsnosti. Stopa zářezu přetínájúca valcovú plochu a kolmé čelo je dokonale těsné i pri zvýšenom protitlaku. Příklad prevedenia výtlačného pružného ventila znázorňuje připojený výkres.The above drawbacks are eliminated by a pressure elastic valve for measuring arterial blood pressure formed from a cylindrical surface provided with a notch. The essence of the solution is that the plane of the notch on the cylindrical flat terminated by the perpendicular face is parallel to the imaginary axis of the cylindrical surface. The size of the thus formed section on the cylindrical flat and perpendicular face is the same as the inner diameter of the cylindrical surface. The pressure relief valve increases the reliability of reuse. The straight-line notch is easy to manufacture, and the possibility of producing shavings that are a source of leakage is completely eliminated. The notch track overlapping the cylindrical surface and the perpendicular face is perfectly tight even with increased back pressure. An example of an embodiment of a discharge spring valve is shown in the accompanying drawing.
Obr. 1 je bokorys výtlačného pružného ventila.FIG. 1 is a side elevational view of a displacement resilient valve.
Obr. 2 znázorňuje výtlačný pružný ventil v náryse. V přístroji je výtlačný pružný ventil osadený do otvoru zosilnenou válcovou plochou 5 s presahom, čím sa dosiahne dokonalá těsnost. Zářez 2 na valcovej ploché 2 a kolmom čele 2 j® vedený tak, že priamka 4 stopy zářezu 3 dělí na polovicu uhol zvieraný válcovou plochou 2 a kolmým čelom 2. Velkost úseku A vytvořeného na valcovej ploché 2 a na kolmom čele 2 je rovnaký ako vnútorný priemer valcovej B.FIG. 2 shows a pressure relief valve in a front view. In the apparatus, the discharge elastic valve is fitted into the opening with a thickened cylindrical surface 5 with an overlap, thereby providing a perfect seal. The notch 2 on the cylindrical flat 2 and the perpendicular face 2j® is guided so that the line 4 of the trench line 3 divides in half the angle formed by the cylindrical surface 2 and the perpendicular face 2. The size of the section A formed on the cylindrical flat 2 and on the perpendicular face 2 is the same as cylindrical inner diameter B.
Vzduch vytlačovaný nafukovacím balónikom prúdi cez narezanú valcovú plochu 2 a koiné čelo 2 v smere od zosilnenej valcovej plochy 5. Po skončení vytláčania sa tieto časti ventila v dósledku pružnosti materiálu vrátia do póvodnej polohy a zabránia tak spatnému prúdeniu stlačeného vzduchu. Výtlačný pružný ventil je možné využit u prístrojov na meranie tepenného tlaku krvi nepriamou metodou ako s deformačným tak i kvapalinovým tlakomerom.The air displaced by the inflatable balloon flows through the cut cylindrical surface 2 and the coil face 2 in a direction away from the thickened cylindrical surface 5. Upon completion of extrusion, these valve portions return to the downstream position due to the elasticity of the material to prevent poor flow of compressed air. The displacement elastic valve can be used in devices for measuring arterial blood pressure by an indirect method with both a deformation and a liquid pressure gauge.
