Description

Technical Field

[0001] The utility model relates to the technical field of chopsticks, in particular to a mainframe and cuff integrated dynamic blood detector. Background Art

[0002] The full name of dynamic blood pressure is non-invasive blood pressure monitoring (ABPM). It is to continuously record the daytime and nighttime blood pressure according to the design mode requirements by wearing a blood pressure recorder, thereby avoiding the objective difference between single blood pressure measurements and the "white coat phenomenon". It helps to screen critical and mild hypertension, help to evaluate the antihypertensive effect of antihypertensive drugs, help to explore the degree of target organ damage and estimate the prognosis, etc. The equipment for measuring dynamic blood pressure is the dynamic blood pressure monitor.

[0003] like Figure 1 As shown, the conventional dynamic blood pressure monitor requires the host 1 to be hung around the waist via a shoulder strap 100 and fixed with a waist belt, the cuff 2 to be tied to the upper arm, and the host 1 and the cuff 2 to be connected with an air tube 200.

[0004] Disadvantages of existing technology:

[0005] 1. The bending of the trachea will affect the measurement and cause blood pressure measurement failure.

[0006] 2. The air release valve of the split-type blood pressure monitor is inside the main unit. Due to the tracheal bend that causes tracheal obstruction, the air release valve cannot deflate the cuff, which may cause a risk of blocking blood flow in the arm and may cause harm to the patient.

[0007] 3. Risk of suffocation due to trachea wrapped around the neck.

[0008] 4. It is inconvenient to wear. The host needs to be worn with a shoulder strap or waist belt, which is cumbersome to operate.

[0009] 5. Due to wearing shoulder straps, waist belts and blood pressure monitor host, patients' movements are restricted and uncomfortable. Utility Model Content

[0031] The working principle of the utility model is as follows: the microprocessor closes two air valves, starts the air pump to inflate, and detects the pressure signals of two sensors while inflating.

While deflation, the signals of two pressure sensors are detected, and the parameters such as systolic pressure, diastolic pressure, mean pressure and pulse rate are calculated through algorithms. After the measurement is completed, the two air valves are opened to deflate at the same time, and the pressure in the cuff is quickly released to 0 mmHg.
