Adjustable recliner or bed

The application relates to reclining chairs or beds that are made of pivoting parts and have a motorized adjustment drive and prevent the user from injury caused by incorrect adjustments by limiting the pivoting movement of the parts of the recliners or beds, and by placing the small-volume adjusting device underneath the recliner or the bed, and by essentially ensuring that the distance between the motors remains unchanged during the adjustment of the recliner or the bed, so that the contour of the adjusting device, even after an adjustment, is essentially the same as the contour of the seating surface of the recliner or bed. The abstract of the disclosure is submitted herewith as required by 37 C.F.R. §1.72(b). As stated in 37 C.F.R. §1.72(b): “A brief abstract of the technical disclosure in the specification must commence on a separate sheet, preferably following the claims, under the heading “Abstract of the Disclosure.” The purpose of the abstract is to enable the Patent and Trademark Office and the public generally to determine quickly from a cursory inspection the nature and gist of the technical disclosure. The abstract shall not be used for interpreting the scope of the claims.” Therefore, any statements made relating to the abstract are not intended to limit the claims in any manner and should not be interpreted as limiting the claims in any manner.

Safe venous blood sampling system with self-locking device

A safe venous blood sampling system with a self-locking device consists of a safe blood sampling needle, a needle holder and a vacuum blood sampling tube jointly. An inner hole of a conical head at the front end of an outer barrel is communicated with an inner cavity of the outer barrel. Three outwards unfolding ribs are arranged on the lower section of the safe venous blood sampling system, the largest diameters of the three outwards unfolding ribs are equal to or smaller than the inner diameter of the outer barrel, pitches among the three outwards unfolding ribs are larger than the width of two inserts, one of theribs is shortened, the bottom of the rib can be supported and locked by the bottom edge of a window on the front side wall of the outer barrel, a spring is compressed in the inner hole of the conical head, and the outer side of the window of the outer barrel is covered by a key contact plate. After blood is sampled, a triggering key is pressed down, the rib is not locked by the bottom edge of the window again, a needle seat is released, the spring resets, a needle tube is driven to retract into the inner cavity of the outer barrel, and a needle tip automatically deviates and is prevented from being exposed again. The inserts which are inclined inwards and forwards are arranged on the side wall of the front section of the outer barrel, an annular bump is disposed on the front section of an end cap of the blood sampling tube, a plurality of arc-shaped bumps are arranged at the lower end of the end cap of the blood sampling tube, the annular bump can be in embedded locking by the insert, the arc-shaped bumps rotatably support to release embedded locking of the insert, the blood sampling tube can be conveniently locked and released, so that blood sampling is safer and reliable, after being used once, the safe venous blood sampling system is destructed, and the needle tip retracts automatically, so that medical staff is protected against needling injury.

GIS loop resistance testing device and method without removing grounding rows

PendingCN108594019AEliminates the risk of electrical injury from inductionSimplify the operation processResistance/reactance/impedenceElectric injuryElectricity
The invention relates to the technical field of a GIS switch loop resistance testing device and particularly relates to a GIS loop resistance testing device and method without removing grounding rows.The testing device comprises a loop resistance tester and a Hall element used for testing a shunt value of a parallel branch, wherein the loop resistance tester is connected between the first grounding row and the second grounding row, the Hall element is arranged on the parallel branch, and an output end of the Hall element is connected with an input end of the loop resistance tester. The testing device is advantaged in that when an actual value of the GIS loop resistance is measured, removing the grounding rows on both sides is not needed, the inductive electric injury risk caused by disassembling the grounding rows can be eliminated, the operational flow of the GIS loop resistance test is simplified, work efficiency of the field can be improved, moreover, the Hall element is utilized to test the shunt value of the parallel branch instead of removing the grounding rows to eliminate shunt influence of the parallel branch, raw materials are readily available, the device is simple, andrelatively good practicality is realized.
