Title: Inrichting voor het reinigen van een stoma in een menselijk of dierlijk lichaam.
Inventor: PETER JACOBUS MARIE COX
IPC: A61H35/00
Filed: 2016-04-04
Granted: 2016-09-05
Abstract: De uitvinding heeft betrekking op een inrichting voor het reinigen van een stoma in een menselijk of dierlijk lichaam. Bij een aspect van de uitvinding is de inlaatopening voorzien van een uitstroomvlak voorzien van meerdere openingen, waarbij de openingen in een concentrische ring langs de buitenomtrek van het uitstroomvlak zijn aangebracht. Zodoende wordt het spoelwater niet rechtstreeks op de stoma-wond gericht, maar direct ernaast op de concentrisch om de stoma-wond omliggende huid. Dit heeft als voordeel dat enerzijds de vervuilde huid direct gereinigd wordt. Daarenboven heeft deze uitvoeringsvorm van de inlaatopening als voordeel dat de omliggende huid rondom de stoma-wond door de waterstralen wordt gemasseerd, hetgeen de doorbloeding van de huid bevorderd en het risico op afsterven of irritaties van de huid aanzienlijk verminderd. Ook hierdoor wordt het comfort voor de stoma-patiënt aanzienlijk verbeterd.

Title: Four-chamber film feedback type sliding block of hydrostatic guide rail
Inventor: WEN ZHAN
IPC: B23Q1/01
Filed: 2022-04-24
Granted: 2023-03-22
Abstract: Disclosed is a four-chamber film feedback type sliding block of a hydrostatic guide rail, which comprises a sliding block body; film feedback devices are fixedly installed at the left end and the right end of the sliding block body respectively by fixing bolts, and an oil inlet is formed in the upper end of the sliding block body. The sliding block is a modular component used for forming a hydrostatic guide rail, and the film feedback devices that are equivalent to flow controllers can be used for adjusting the flow of hydraulic oil in four oil chambers; the pressure change of the hydraulic oil can also be detected by oil pressure detection sensors, so that the error condition in installation of the sliding block is observed, and targeted error adjustment is carried out, so as to greatly improve the assembly accuracy of the guide rail and ensure that the completely installed hydrostatic guide rail has the same oil film stiffness and property at all positions; and in addition, since the positions of the flow controllers formed by utilizing elastic film sheets are very close to the positions of a front side oil chamber, a rear side oil chamber, a lifting oil chamber and a maintaining oil chamber, an oil path can also be effectively shortened, and the dynamic stiffness is ensured.
