Description

Desk-top sphygmomanometer and disinfection system thereof

Technical Field

The invention belongs to the field of medical appliances, and particularly relates to a table sphygmomanometer and a disinfection system thereof.

Background

The systemic arterial blood pressure is called Blood Pressure (BP) for short. Blood pressure is the pressure acting on the wall of a blood vessel when blood flows in the blood vessel, and is the driving force for driving the blood to flow in the blood vessel. The ventricles contract and blood flows from the ventricles into the arteries, at which time the pressure of the blood against the arteries is highest, called the Systolic Blood Pressure (SBP). The ventricles relax, the arterial vessels retract elastically, and blood continues to flow slowly forward, but the blood pressure drops, at which point the pressure is called the Diastolic Blood Pressure (DBP).

Blood pressure of a dialysis patient needs to be measured before and after hemodialysis treatment so that a doctor can accurately evaluate the condition of the patient, and the blood pressure is also an important basis for the doctor to adjust a dialysis prescription and a medication prescription. Because the measuring accuracy of the table type sphygmomanometer is high, the table type sphygmomanometer is mostly used in dialysis rooms of various hospitals at present, a large number of dialysis patients are received and diagnosed in the dialysis rooms every day, each patient needs to measure the blood pressure for at least 2 times, and the use frequency of the sphygmomanometer is very high. The current desktop sphygmomanometer in the market can only wipe and disinfect the outer surface of the desktop sphygmomanometer due to the lining cloth used in the blood pressure collecting cylinder. Although the lining cloth can be disassembled, the disassembly and the assembly are difficult, so that one person can not disinfect one by one, and the lining cloth can only be disassembled, cleaned and disinfected after the treatment is finished every day, thereby increasing the risk of cross infection.
