Embodiment 1

[0020] Embodiment 1, basically as attached figure 1 , figure 2 Shown: a multifunctional device for venous blood collection, including an arm bracket and a blood collection tube bracket, the arm bracket and the blood collection tube bracket are vertically distributed and detachably connected. The blood collection tube holder includes a blood collection tube holder 16 and a base 13, the blood collection tube holder 16 is laterally slidably connected to the base 13, and the base 13 is provided with a transmission mechanism for driving the blood collection tube holder 16 to translate laterally on the base 13, and for driving The jacking mechanism for the vertical translation of the blood collection tube on the blood collection tube rack 16 . The blood collection tube holder 16 is in the shape of a rectangular block, and the blood collection tube holder 16 is provided with eight slots 15 arranged side by side with upper openings. Evenly distributed along the length direction of ...

Embodiment 2

[0026] Embodiment 2, the difference between this embodiment and embodiment 1 is that an ultraviolet lamp is arranged in the isolation cover 2, combined with image 3 Shown, be provided with power supply 28 in the groove, be provided with switch 29 in the air box 25, columnar airbag 27 inner tops are provided with switch switch knife 30, ultraviolet light, power supply 28, switch 29, switch switch knife 30 are connected in series. When not drawing blood like this, there is no inflation in the columnar airbag 27, and the collapse of the columnar airbag 27 allows the switch knife 30 to close the switch 29, so that the ultraviolet lamp can be energized, and then the ultraviolet lamp carries out ultraviolet disinfection and sterilization to the inside of the isolation cover 2.

[0027] The specific implementation process is as follows: when not drawing blood, the air release valve 11 and the pressure relief valve 10 are all closed, the columnar air bag 27 collapses and shrinks, and ...

Abstract

The invention discloses a multifunctional device for venous blood collection in the field of blood pumping devices, which includes an arm bracket and a blood collection tube bracket, which are vertically distributed and detachably connected; The frame and the base, the blood collection tube frame is horizontally slidably connected to the base, and the base is provided with a transmission mechanism for driving the blood collection tube to translate laterally on the base, and a jacking mechanism for driving the blood collection tube to translate vertically on the blood collection tube frame , the arm bracket includes a supporting board, the supporting board is connected with a holding air bag, and the holding air bag, the transmission mechanism and the jacking mechanism are sequentially connected; the supporting board is also connected with a cuff. The invention can improve the problem that in the existing blood drawing operation process, each tool is operated in a decentralized manner, and the inter-correlation weakly affects the efficiency.

Description

technical field [0001] The invention relates to the field of blood drawing devices, in particular to a multifunctional device for taking blood from a vein. Background technique [0002] Blood test is one of the most common and effective testing methods in the process of medical diagnosis and treatment. By collecting blood samples and detecting and analyzing various indicators, the health status of the human body can be accurately judged. In the routine blood collection process, the patient exposes one arm to the elbow, and uses a cuff to tie the upper side of the elbow to slow down the blood backflow of the distal antecubital vein. It is prominent and easy to insert the needle, and the vein is punctured with a special syringe. The medical staff takes the vacuum blood collection tube and connects it with the needle. The negative pressure in the vacuum blood collection tube sucks the blood in the vein into the blood collection tube. This method of blood collection has some di...
