Abstract
The device for reminding the seepage of the medicine in the venous transfusion comprises a pressure detection mechanism and a reminding mechanism, wherein the pressure detection mechanism is arranged in a push injection force transmission link of a transfusion device, and when the medicine seepage and push injection force in the transfusion process changes, the reminding mechanism gives out a sound for reminding. The pressure detection mechanism is arranged in a pushing injection force transmission link of the infusion apparatus (pump), and when the medicine seeps out of the pushing injection force and changes, the reminding mechanism sends out sound to remind medical staff. The device has the functions of timing patrol and real-time reminding of drug exudation, and reduces the injury and pain of patients caused by careless omission. The nursing quality is improved, the infusion treatment effect is improved, and doctor-patient disputes and medical accidents are reduced.
Description
Technical Field
The utility model relates to a medical facility, in particular to a reminding device for medicine exudation in intravenous infusion.
Background
An intravenous infusion set (pump) is an infusion device which utilizes an electric appliance to control mechanical driving force to inject liquid into human veins, and the device has small volume and light weight, so the intravenous infusion set (pump) is widely applied. However, during the intravenous infusion, the phenomenon that liquid seeps into the extravascular tissue space often occurs. All infusion sets (pumps) in the prior industry have no functions of liquid extravasation alarming, reminding and the like.
If extravasation of fluid is not detected in time, the drug can cause local damage to the human body, such as cytotoxic drugs, vasoactive drugs, and the like. In addition, after the amount of extravasation reaches a certain level, blood vessels under the skin are compressed by the extravasation, resulting in skin necrosis and even more, tissue necrosis.
The occurrence of the above situation not only reduces the therapeutic effect of the drug, but also brings harm and pain to the patient, especially in the treatment of neonates. The device for reminding the exudation of the intravenous infusion medicines accords with the technical operating specifications of intravenous therapy nursing, provides timing patrol reminding and medicine exudation reminding, and can freely record reminding sound, so that nursing staff can work in a warm environment instead of working in fear in alarm sound of tension and urge all the time, and accidents are better reduced.
Disclosure of Invention
In order to solve the defects of the prior art of the infusion apparatus (pump) in the industry, the utility model aims to provide a method for automatically reminding nursing staff when the problems of medicine seepage, medicine extravasation and medicine extravasation occur by monitoring the infusion injection pressure in real time when the infusion apparatus (pump) is used, so that the physical and mental injuries and medical and patient correction (accidents) caused by the medicine seepage to a patient can be greatly reduced.
In order to achieve the purpose, the technology of the utility model provides the following technical scheme: comprises a pressure detection mechanism and a reminding mechanism. The infusion thrust pressure detection mechanism is arranged in a force transmission link from a power motor of an infusion apparatus (pump) to an infusion empty needle to monitor the current infusion pressure (the pressure detection precision is 1N +/-0.1N), and the infusion pressure information is transmitted to the reminding mechanism to be processed and judge whether extravasation or other infusion problems exist to call and remind medical care personnel.
According to the technical scheme, the pressure detection mechanism detects that the current push pressure is transmitted to the reminding mechanism for processing and operation, and data interaction, processing, application and the like are carried out on the information through the interface and the hospital medical care system.

Detailed Description
In fig. 4, the resistive strain semiconductor 12 is mounted on the deformation substrate 11, and the deformation substrate 11 is mounted in the pressure detection mechanism 1.
In fig. 2, a state display and operation screen 21, a custom sounding reminder module 22 and a wired or wireless data interface 23 are installed in the reminder mechanism box 2 in fig. 3.
The utility model discloses a reminding device for medicine exudation in intravenous infusion, which comprises a pressure detection mechanism 1 and a reminding mechanism 2 in a graph 2, wherein the reminding mechanism 2 is mounted on an infusion apparatus 11 (pump) or integrated in the infusion apparatus, and the pressure detection mechanism 1 is arranged in an injection force transmission link of the infusion apparatus 11 (pump).
In fig. 4, the resistance-type strain semiconductor 12 attached to the infusion apparatus 11 (pump) is deformed when receiving the force of pushing the empty needle, and at the same time, the resistance-type strain semiconductor 12 transmits the pressure information to the single chip microcomputer core control system 3 in the reminding mechanism 2 for processing and sending out corresponding operation.
The principle of the resistive strain semiconductor 12 in fig. 4 is as shown in fig. 6, and referring to fig. 5, the structure thereof includes a film base layer 15, a metal resistive strain sensitive sheet 14, and a film lamination layer 13.
Referring to fig. 2 and 3, the reminding mechanism 2 includes a custom sounding reminding module 22, a status display and operation screen 21, and a wired or wireless interface 23.
When the single chip microcomputer core control system 3 in the reminding mechanism 2 receives the pressure information transmitted to the single chip microcomputer core control system 3 by the resistance type strain semiconductor 12 in the pressure detection mechanism 1 for operation processing, the accurate judgment information is transmitted to the state display and operation screen display 21 and the user-defined sounding reminding module 22 for sending personalized reminding so as to achieve the purpose of routing inspection by the nursing staff, and meanwhile, the information is transmitted out through the wired or wireless data interface 23 for other information systems.
The resistive strain semiconductor 12 recognizes the injection force with a pressure accuracy of 1N ± 0.1N.
