Description
Technical Field
The invention belongs to the technical field of medical auxiliary instruments, and particularly relates to an infusion auxiliary device for an infusion bag and a construction method of a temperature and pressure control model.
Background
At present, a disposable infusion set and an infusion bag are adopted for clinical intravenous infusion, but in clinic, when a special critical patient is frequently rescued or treated, the infusion speed is required to be increased, and when a liquid regulating valve is opened to the maximum, the flow rate of the infusion valve cannot meet the requirements, so that great inconvenience is brought to rescue and treatment work, and meanwhile, for the patient (shock patient, aged and weak patient, patient with more blood loss, etc.) with special condition and/or the process of injecting the liquid medicine with lower temperature in the infusion bag into the vein of the patient at lower ambient temperature, the patient can be caused to have the symptoms of losing temperature (hypothermia), and a certain danger is generated for life safety of the patient.
In order to solve the above problems, the methods/apparatuses currently used are as follows:
(1) The warm water bath is used for preheating the infusion bag to be used so as to improve the infusion temperature of the infusion bag, and a special person squeezes the infusion bag so as to accelerate the infusion rate of the infusion bag.
(2) Referring to the chinese patent CN112245710a in the prior art, a disposable infusion bag with an interlayer is used, and the interlayer of the disposable infusion bag is rapidly inflated and expanded by the gas generated by the reaction of the chemical agents, so as to pressurize the liquid medicine in the infusion bag, thereby accelerating the infusion rate.
(3) Referring to the Chinese patent CN105411846A in the prior art, an electric heating layer is wound around the periphery of the infusion bag, so that the liquid medicine in the infusion bag is heated.
(4) Referring to the chinese patent CN112089925B in the prior art, an automatic blocking heating and pressurizing infusion device is used, the temperature is controlled by wrapping a heater and a temperature sensor in the middle section of the infusion tube, and the pressure of the infusion bag wrapped inside the pressurizing bag is increased by pressurizing the pressurizing bag, so that the flow rate of the infusion bag is increased.
However, the method/device for accelerating the infusion rate and increasing the infusion temperature of the infusion bag in the prior art has the following problems:
(1) The method of heating and squeezing the infusion bag by the warm water bath is time-consuming and labor-consuming, the preheated infusion bag is gradually cooled as time passes, the risk of causing the symptoms of losing temperature of patients in infusion still exists, and the method of squeezing the infusion bag cannot be well and accurately matched with the infusion rate.
(2) The Chinese patent CN112245710A is a disposable pressurized transfusion bag which can not be repeatedly used, wastes resources and is not environment-friendly, the pressurizing mode (the pressurizing mode is that the interlayer of the transfusion bag is rapidly inflated and expanded through the gas generated by the chemical agent reaction so as to pressurize the liquid medicine in the transfusion bag) is too rapid, the pressurizing amplitude in the pressurizing process is uncontrollable, meanwhile, the continuous pressurized transfusion can not be realized for a long time, meanwhile, the pressure increase of the device and the transfusion rate enhancement degree of the transfusion bag can not be visually displayed, the pressurizing amplitude is a fixed value because the gas generated by the chemical agent reaction is a fixed quantity, the pressurizing amplitude is only suitable for specific transfusion scenes, the pressurizing amplitude of the transfusion bag can not be changed according to the actual physical condition and emergency degree of a patient, the accelerated transfusion rate of the transfusion bag can not be regulated, and the device has no heating function.
(3) The Chinese patent CN105411846A provides a heatable infusion bag which is a disposable product, is discarded after the infusion is finished, has serious resource waste and loss, can only regulate and control heating power, but cannot intuitively observe the actual heating temperature corresponding to the infusion bag, so that the regulated and controlled heating power cannot be matched with the heating temperature correspondingly, the heating temperature of the infusion bag is difficult to accurately regulate and control, and meanwhile, the infusion bag has no pressurizing function.
(4) The Chinese patent CN112089925B controls the temperature by wrapping the heater and the temperature sensor in the middle section of the infusion tube, when the infusion rate is too fast, the heater wrapped in the middle section of the infusion tube often cannot heat the liquid medicine in the infusion tube efficiently, so that the actual infusion temperature is a certain gap from the expected infusion temperature, and because the heater is wrapped in the middle section of the infusion tube (cannot be wrapped at the tail end of the infusion tube, so that the injection of the vein end of a patient is influenced), the middle section of the infusion tube still has a certain distance from the vein end of the patient, the distance still causes temperature loss, and meanwhile, the device cannot set the accurate infusion temperature and the accurate infusion rate, and cannot be related and matched (when the infusion rates are different, the temperature loss in the infusion tube is different).
