Description

Medical desk type blood sampling and pulse pressing device

Technical Field

The utility model relates to a medical desk-top blood sampling vein pressing device, in particular to a medical desk-top blood sampling vein pressing device of a serum sample collection window in the medical and health field.

Background

In the medical and health field, in the process of treating patients, the superficial veins of the elbow body of a human body are usually selected for collecting serum samples, the pulse-pressing hemostasis method is a tourniquet bundling method, and the adopted tourniquets are rubber tubes or flat sheet bands made of natural rubber. In medical institutions in various regions in China, on one hand, the tourniquet has the phenomena of repeated use, cross use, random storage, no disinfection or incomplete disinfection and the like in the use process, and the common problem of serious pollution of the tourniquet generally exists; on the other hand, when the tourniquet is used, medical staff need to tie up the tourniquet at the proper position of the upper arm of a patient, the blood serum sample is collected, the tourniquet needs to be untied by the medical staff and placed at a medical waste recycling position for uniform treatment, and therefore the work efficiency is problematic, and the labor intensity of the medical staff is also imaginable after one day. Certainly, the pulse-pressing hemostasis method is suitable for clinical ward, outdoor mobile temporary treatment places and the like, but in the era of rapid development of scientific and technological medical services, at present various advanced medical instruments and equipment such as CT and the like are widely put into use, a fixed serum specimen acquisition window facing to a large number of patients in medical institutions is still operated by using the tourniquet bundling technology, the contrast that the high-tech diagnosis and treatment technology is not suitable for the traditional lagging technology is generated in a real time, and the realization of the synchronous development of the modern medical diagnosis and treatment services and the window image construction of the medical institutions are influenced to a certain extent.

SUMMERY OF THE UTILITY MODEL

In order to avoid the problem that traditional rubber tourniquet used repeatedly, alternately used, pollutes and exceeds standard that the use exists, alleviate medical personnel intensity of labour, improve work efficiency, the utility model provides a medical desk-top blood sampling tourniquet. The medical table type blood sampling and pulse pressing device comprises an upper opening and closing body and an upper opening and closing body driving system; the device comprises a lower fixing body, a slider screw driving system, a pressure sensor, a disposable sterilizing paper tape and a sterilizing paper tape traction and shearing system. When the pulse pressing device works, after the arm of a patient is placed at a designated position, medical staff only need to touch the pulse pressing button, and the device automatically enters a closing and pulse pressing sliding block contracting and stops a keeping procedure. At the moment, the medical staff performs blood sampling operation, the serum sample is collected, the medical staff only needs to touch the release button, and the equipment automatically enters the release pulse pressing sliding block and the opening procedure. When the arm of the patient is removed, the medical staff touches the paper changing button, and the equipment enters a sterilizing paper tape changing and automatic cutting program. At this point, the procedure for one cycle is complete and patient alternation can proceed to the next cycle. Medical personnel can finish all the work contents of pulse pressing only by touching related buttons for three times in the whole process, the labor intensity is greatly reduced, and the problems of cross use, repeated use and tourniquet pollution of the traditional rubber tourniquet are avoided because the sterilization paper tape is replaced in each procedure.

The beneficial effects of the utility model are that the automation, intellectuality, aseptic technique and the purpose that alleviates medical personnel intensity of labour of pressing the arteries and veins in the blood sampling have just been realized.
