Description

Portable medical pressure monitoring device

Technical Field

The invention relates to a pressure monitoring device, in particular to a portable medical pressure monitoring device.

Background

The invasive arterial pressure monitoring is to puncture and place a tube in the peripheral artery, and the pressure sensor is connected with the monitor to reflect the blood pressure change condition of each cardiac cycle, so that the systolic pressure, the diastolic pressure and the average arterial pressure can be directly displayed. The invasive arterial pressure monitoring has the advantages of being free from the influence of external factors such as manual pressurization, decompression, loose sleeve belt and the like, being capable of accurately, visually and timely finding out instantaneous arterial blood pressure change and the like, being capable of taking arterial blood for analysis, reducing the trouble of repeated puncture, being capable of relieving the pain of a patient to a certain extent and gaining valuable time for medical operations such as rescue and the like.

Currently, in arterial pressure monitoring, heparin water is required to prevent blood coagulation and the like. Specifically, the artery puncture tube is connected to the heparin water storage bottle through the tube connection pipeline, and in order to ensure the reliability of the connection between the tube connection pipeline and the heparin water storage bottle, a medical adhesive tape is generally wound around the joint portion between the tube connection pipeline and the heparin water storage bottle, so as to avoid the separation between the tube connection pipeline and the heparin water storage bottle during the pressurization process.

As known to those skilled in the art, when a medical adhesive tape or the like is used for winding and fixing, the problems of complex operation, low efficiency and the like exist. In addition, in the arterial pressure monitoring process, operations such as pressurization and the like are required, manual pressurization is mainly adopted at present, and the pressurization frequency and the pressurization effect are difficult to ensure; and when pressure was too big, cause the separation of putting pipe connecting line and heparin water containing bottle easily to can lead to spraying of heparin water, lead to the fact the circumstances such as pollution of arterial pressure monitoring environment from this, the demand of steady monitoring among the unable effective satisfaction arterial pressure monitoring etc.

In many high-risk operations, such as advanced surgery, surgery involving many complications, cardiac surgery, transplantation surgery and orthopedic surgery, arterial blood sampling and testing are very important, and various indexes in a patient body can be accurately analyzed. More importantly, blood needs to be taken for many times in the operation, the operation is complicated, and the pollution to a sampling port is easily caused, so that the blood infection of a patient is caused. Meanwhile, after blood is taken, heparin water is required to be manually used for flushing the artery pressure measuring pipeline, so that the phenomenon that the artery pipe placing pipeline is blocked due to the fact that residual blood is coagulated after the blood is taken from the pipeline is avoided, the heparin water is often used excessively during flushing, and excessive heparin enters the blood, so that a low-coagulation state is possibly caused, and the operation is not facilitated.

Meanwhile, in some outgoing operations, such as obstetric critical operations, emergency department intervention operations and the like, an operation room is often lack of invasive artery monitoring equipment, and for the patients, invasive artery monitoring is very important, and the invasive artery monitoring equipment is lacked to ensure the operation safety.

Meanwhile, when the operation is finished, the patient is often required to be transferred from the operating room to an intensive care unit, and in the way of transfer, the invasive arterial blood pressure of the patient is often required to be monitored.

Moreover, some patients have stable vital signs after the operation, and after returning to the surgical ward, the patients often have serious postoperative complications due to changes of the disease conditions. The patients need to keep invasive arterial pressure for monitoring for 2-3 days after operation, so that arterial blood samples can be conveniently extracted at any time for detection and assay, the disease change of the patients can be found as soon as possible, and the patients can be treated as soon as possible so as to avoid disease deterioration. These patients need to monitor invasive arterial pressure, but the ward lacks an arterial pressure monitoring device, and invasive arterial pressure monitoring cannot be achieved. When the illness condition is worsened for rescue, invasive artery catheterization monitoring is very important, and the effectiveness of rescue can be improved to the greatest extent. Based on this, it is very important to keep having the artery of creating and provide pressure monitoring equipment several days after the operation, but the present situation is, ward lacks the pressure monitoring equipment that creates, and the artery is put the pipe and just is extracted when the operation is ended, and patient uses the monitoring of non-invasive artery pressure after returning the ward, and monitoring effect is poor on the one hand (monitoring time interval is long can not provide real-time supervision like having the artery monitoring of creating), and on the other hand does not have the artery pressure monitoring sleeve area discontinuity high pressure and aerifys the gassing of creating, seriously disturbs patient's postoperative rest, seriously influences patient's postoperative rehabilitation.

In primary hospitals, invasive arterial pressure monitoring is difficult to realize due to lack of equipment, and even if doctors at higher levels consult, invasive arterial pressure monitoring is difficult to provide when needed, so that hidden dangers are buried in operation safety.

Based on the aforesaid is various, clinical urgent need an artery monitoring pipeline, can make things convenient for convenient implementation to have invasive artery monitoring management in the art, and the pipeline that avoids the pressurization to lead to drops, avoids getting blood repeatedly and washes various complications, and is loaded down with trivial details when avoiding patient to transport, also can be provided with invasive artery pressure monitoring and arterial blood sampling chemical examination at the postoperative to reduce the influence of monitoring time measuring to patient's rest.
