Description

Whole blood or blood component blood sampling pad of comfortable adjustable length

Technical Field

The utility model belongs to the technical field of auxiliary medical instruments, and particularly relates to a comfortable type whole blood or component blood sampling pad with adjustable length.

Background

The elbow needs to be heightened and straightened during blood sampling, so that the elbow of a common blood sampling device can be heightened by a simple cushion, hands and/or wrists are not supported, the elbow of the arm is generally required to be immobile after a blood sampling needle is fixed in order to avoid the falling of a needle, and the hands and/or wrists are in a suspension state in the whole blood sampling process, so that discomfort is caused. When a person lies on a bed to take blood, the width of the bed is limited, and the hand and/or wrist often droop when the person lies in a lying position to take blood.

The blood sampling pad in the prior art is designed for short-term blood sampling, and the hand and/or the wrist are drooping and have poor comfort and the arm and the hand are easy to move during blood sampling. The blood component is taken separately for 20-70 minutes, the wrist and the hand are not comfortable due to the existing blood taking pad, and a plurality of tubes need to be fixed by adhesive tapes in the process of taking the cell component separately, so that the blood component is very messy and unsafe.

The utility model has the specific technical scheme that the comfortable type whole blood or component blood sampling pad with the adjustable length comprises a preformed sponge pad, a telescopic bottom plate and an elbow pad, and is characterized in that the preformed sponge pad is provided with an upper surface matched with the shape of an arm, the lower surface of the preformed sponge pad is fixed on the telescopic bottom plate, the telescopic bottom plate comprises a sleeve plate and a telescopic tongue plate, the sleeve plate is provided with a cylindrical structure with a rectangular cross section, the telescopic tongue plate can move in the cylindrical structure of the sleeve plate, and the elbow pad is arranged on the upper surface of the preformed sponge pad and is positioned below an elbow during blood sampling.

Further, the pre-formed foam pad has a groove on an upper surface thereof, and a lower portion of the elbow pad is inserted into the groove.

Furthermore, the telescopic base plate further comprises a spring clamp, and the spring clamp is arranged on the side surface of the telescopic base plate.

Furthermore, the telescopic base plate further comprises a plurality of lantern rings which are symmetrically arranged on the side surface of the telescopic base plate.

Furthermore, the telescopic tongue plate fixing device further comprises a butterfly bolt, wherein the butterfly bolt is arranged in a through hole with internal threads on the side surface of the telescopic bottom plate, and the relative positions of the sleeve plate of the telescopic bottom plate and the telescopic tongue plate can be fixed by rotating the butterfly bolt.

Further, the material of the preformed foam pad is memory foam.

The whole blood or component blood sampling pad has the advantages that 1) the whole blood or component blood sampling pad is provided with the preformed spongy cushion matched with the shape of the arm, can support the arm, the wrist and the hand, and solves the problem of hand and/or wrist droop during blood sampling; 2) the preformed spongy cushion is arranged on the telescopic bottom plate and can be matched with the arm lengths of different people; 3) the preformed sponge cushion material is a memory sponge, so that the comfortable sensation is increased, and the arms and the hands are not easy to move; 4) the side surface of the telescopic bottom plate is provided with a spring clamp which can fix the blood sampling pipeline; 5) The side surface of the telescopic bottom plate is provided with a lantern ring which can be provided with a binding band or a plastic hasp and is used for fixing the blood sampling pad on the armrest of the blood sampling chair; 5) the elbow pad with the variable thickness enables the included angle of the arm to be more convenient for puncturing the needle head;

6) the preformed spongy cushion is made of memory sponge, so that the arm is more comfortable during blood collection.

The whole blood or component blood sampling pad can increase the stability of the arm during blood sampling, is not easy to roll, and avoids the displacement of the needle head or the puncture of the blood vessel caused by the movement of the arm. Can also increase the arm comfort of the uncompensated blood donor, thereby improving the blood donor experience.
