In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.
[0033] In addition, the term "same" does not mean that the parts must be absolutely the same, but slight differences are allowed. The term "vertical" only means that the positional relationship between the parts is more vertical than "parallel", and does not mean that the structure must be completely vertical, but can be slightly tilted.
[0034] See also Figure 1-9 The utility model provides a technical solution: a blood extraction and pulse compression device, comprising a base 2 and a pulse compression belt 1 arranged on the base 2, both ends of the base 2 are provided with side panels 3 extending upward, the pulse compression belt 1 is suspended between the two side panels 3, the pulse compression belt 1 is an annular structure with an opening at the bottom, and the two ends of the opening extend to both sides and are respectively connected to the two side panels 3.
[0035] The base 2 is placed on an operating platform such as a blood sampling window as a mounting structure, and the side panels 3 arranged at both ends of the base 2 serve as the mounting base of the compression cuff 1. The compression cuff 1 can be made of a solid rubber strip or a hollow rubber tube in an inflated state, so as to facilitate its maintaining a ring shape above the base 2 and to enable it to have a certain supporting effect. The ring structure can maintain a suspended state with a certain movable distance from the base 2. The two ends of the compression cuff 1 are respectively connected to the two side panels 3, and the middle part is wound into an upwardly protruding ring, which is used to tie the arm of the person whose blood is being drawn. During operation, the person whose blood is being drawn can The arm is inserted into the annular structure and then pressed down. Since the two ends of the compression cuff 1 are connected to the two side plates 3, when it moves downward under pressure, the distance between it and the side plates 3 increases, and the compression cuff 1 will be stretched, causing the annular structure to contract, thereby binding and pressuring the arm of the person whose blood is being drawn. When the binding state needs to be released, the person whose arm is being drawn only needs to lift up, and the compression cuff 1 will be reset by its own elastic contraction. There is no need for the nurse to manually bind and unbind, which reduces the nurse's workload.
