Description

Automatic interchange self-lock device of infusion bottle

Technical Field

The invention relates to an infusion auxiliary device, in particular to an automatic interchange self-locking device for infusion bottles.

Background

At present, many patients in hospitals need transfusion, some patients need to carry out multi-bottle transfusion due to illness state, under the condition of more patients, the workload of medical staff is greatly increased, and the risk of blood backflow of the patients is increased because the number of the medical staff is less and the bottle replacement transfusion treatment is not carried out in time. Therefore, there is a need to develop an automatic transfusion and fluid-changing device, which can automatically change the transfusion and fluid under the condition that the medical staff fails to change the bottle in time, so as to reduce the risk of blood backflow of the patient. Therefore, researchers do many studies and obtain many satisfactory effects, for example, the current development and application prospects of the full-automatic infusion and liquid-changing device are disclosed in the 5 th volume 17 th volume 5 th volume of 2020 of Chinese medical equipment, wherein the following are pointed out: the combination clinical demand finds that the full-automatic infusion liquid-changing device needs to have the advantages of suspensible, movable, small volume, long standby time, simple operation and the like, and the development is imperative. Researchers develop and complete the full-automatic transfusion liquid changing device according to different design principles, and the device is mainly divided into 4 types according to the principle, and each type has the advantages and the disadvantages and needs to be perfected continuously. The principles, advantages and disadvantages of these four types of devices are specifically as follows:

the first type is a pressure valve controlled by a physical method, the principle is that the pressure difference of liquid is combined with a valve to meet the requirements of liquid changing and stopping, the liquid changing valve has the advantages of automatic liquid changing and simple operation, and has the defects of high requirement on the hanging height of a transfusion bottle and easy mixing of medicines;

the second type is a floating valve controlled by a physical method, the aim of liquid changing and stopping is achieved by a membrane structure, and the floating valve has the advantages of automatic liquid changing, simple operation, higher cost, more complex structure and easiness in mixing liquid medicine;

the third type is a physical and intelligent control centralized air inlet pipe which consists of a sensor, a central controller, a mechanical part and an air inlet part, has compact structure, complete functions and convenient use, needs to customize an infusion apparatus, has higher air tightness requirement, and has no blocking device on a liquid path trunk;

the fourth type is intelligent control-gravity drip, which is composed of a sensor, a central controller and a mechanical part, and has complete functions, simple operation, easy interference of the selected sensor, poor blocking effect and potential safety hazard.

The principle of controlling the pressure valve by the full-automatic transfusion liquid-changing device through a physical method is that the pressure difference generated by the suspension height is utilized to control the valve, so that automatic liquid changing is realized. The principle of controlling the floating valve by a physical method is to utilize a liquid stopping film to realize air permeability and liquid impermeability and to complete liquid change by matching with pressure difference. The two physical liquid changing schemes are easy to cause the danger of medicine mixing, the air emptying is easy to exceed the buffering limit of the Murphy's dropper, the safety accident that air enters the blood vessel of a human body occurs, and the automatic liquid changing is not really realized.

A full-automatic liquid changing device developed according to the principle of physics and intelligent control of a centralized air inlet pipe is characterized in that all liquid hanging bottles are hung sequentially and simultaneously and connected through a liquid conveying pipeline, and an air inlet guide pipe of each bottle of liquid is placed in an air inlet valve controller in a centralized mode and sealed. The device below has a comprehensive sensor that is used for detecting whether have liquid and bubble etc. in the transfer line, with signal transmission to the control core that detects, and control core handles the back and gives the motor, and the motor drives the valve and moves forward and open in proper order, makes the intake pipe admit air in proper order, and the liquid bottle begins the dropping liquid in proper order, reaches the purpose of changing liquid automatically. Compared with the two physical control principles, the device really achieves the aims of automatic liquid changing and accurate control. But the device is limited to be popularized due to the defects of limited moving range, relatively large volume and the like.

The full-automatic transfusion liquid-changing device developed according to the intelligent control-gravity drip type principle is composed of 3 modules of a sensor, a central controller and a mechanical part, a plurality of transfusion bottles are connected through a multi-puncture needle transfusion device, the dripping speed of a Murphy's dropper is detected by utilizing a photoelectric or other detection device, each branch is provided with a switch to control the on-off of a pipeline, when the interval of liquid drops in the Murphy's dropper is large, the pipeline is switched, and the alarm prompt is given after all the pipelines are switched. Compared with the above 3 control principles, the device can avoid the problems of medicine mixing, air mistakenly entering blood vessels and the like, and has the advantages of easiness in suspension, large moving range, light volume, energy conservation, emission reduction and the like.

The full-automatic infusion of fourth type according to intelligent control-formula principle development is dripped to gravity trades liquid device, though the function is complete, easy operation, but the easy quilt of selected sensor is disturbed, blocks that the effect is relatively poor, has the potential safety hazard, the utility model discloses improve to blocking the poor problem of effect. The utility model discloses thereby utilized the spring to reply when gravity alleviates and switched on the electro-magnet, realized the infusion at last and traded the liquid function. The spring return structure is low in cost, reliable in work and extremely low in potential safety hazard. The spring is used for replacing the electronic sensor, so that the reaction speed of the device is improved, and the blocking effect of the device is improved.
