Portable physiological parameter remote measuring device with sampling and medicine perfusion functions

Abstract

The invention discloses a portable physiological parameter remote measuring device with sampling and medicine perfusion functions. The device comprises a flow passage body, a wireless sensor unit, an inlet end conduit and an outlet end conduit, wherein the flow passage body is of a flow structure and is provided with inlet and outlet end mounting holes and a fluid cavity on the middle part of the body; the wireless sensor unit is arranged in the body for detecting a state of fluid entering the fluid cavity and is wirelessly communicated with exterior; one end of the inlet end conduit is communicated with a fluid source of a remote measuring object, and the other end of the inlet end conduit is connected with the inlet end mounting hole in a matching manner; and one end of the outlet end conduit is connected with the outlet end mounting hole in a matching manner, and the other end of the outlet end conduit is connected with a three-way valve. The invention also discloses other structural forms of the device. According to the device, bubbles can be effectively prevented from being detained in the device, the stability for fluid state transfer and the pressure measuring precision are guaranteed; and in addition, the device can also realize functions such as sampling and medicine perfusion, and has the advantages of small size, light weight, wide application range and the like.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, and more specifically relates to a portable physiological parameter telemetry device with both sampling and drug perfusion functions, which can successfully realize the cardiovascular pressure, blood flow, blood oxygen saturation, etc. of human or animals. At the same time as the wireless telemetry of physiological parameters, other functions such as sampling and drug perfusion can also be realized through the adjustment of components. Background technique [0002] In the process of disease diagnosis and treatment, it is often necessary to measure multiple physiological parameters of the human body, so as to provide important reference data for disease diagnosis and treatment according to the variation state of physiological parameters. Taking blood pressure parameters as an example, blood pressure is not only an important vital sign, but also the most commonly used indicator for judgin...

Problems solved by technology

The advantage of this implantable telemetry device is that it can monitor the 24-hour blood pressure, heart rate and daily cycle changes of freely moving objects in real time, but there are still the following defects or deficiencies: first, for mice less than 17 grams , such telemetry devices are still too large and heavy (even the smallest DIS telemetry blood pressure transmitter, PA-C-10 implant, still weighs 1.4 grams and has a total volume of 1.1 ml), which affects the The diet and physical activity of the implanted mice will reduce the weight and blood pressure of the mice, which will affect the animal experiments related to blood pressure (such as the observation of blood pressure in animal models of hypertension and cardiovascular disease), especially after implantation. The first two weeks; second, the most accurate models of this type of telemetry device were not able to accurately measure left ventricular systolic capacity (LVdP / dt max and LVdP / dt min ), limited applicability; third, this implantable telemetry device is a non-flow hemodynamic telemetry delivery system, so blood sample collection and drug perfusion experiments are impossible; fourth, its replacement battery is expensive, ( Such as the A-C-10 implant, it costs 420 euros to replace a new battery, and the continuous service life of the battery is 45 days), and DSI company must be responsible for the replacement, and there are corresponding shortcomings such as high cost and inconvenient operation. At present, there are only a few researches in China. Personnel can use this blood pressure telemetry system; Fifth, the pressure sensor of the diaphragm of this implantable telemetry device is very fragile. In addition, during the long-term continuous recording of blood pressure, once the pressure transmission medium at the end of the catheter is replaced by blood, blood clots or air bubbles may be formed, thereby weakening or disappearing the blood pressure signal
