Problems solved by technology

However, the existing automatic liquid change system is not only complicated in structure, but also the automatic liquid change system is integrated with the infusion set, and the infusion set is usually a disposable infusion set. The system is all scrapped, which not only greatly increases the use cost of the infusion set, but also wastes resources

Embodiment 1

[0057] like figure 1 As shown, an automatic fluid exchange system is provided in this embodiment, including a controller 111, an infusion control unit 108, and a liquid detection unit 112. The controller 111 is connected to the infusion control unit 108 and the liquid detection unit 112 respectively, wherein,

[0058] The infusion control unit 108 is detachably arranged on the infusion set, and the infusion control unit 108 is used for connecting or disconnecting the puncture tube 101-2 in any puncture module 101 in the infusion set under the control of the controller 111; Whether the liquid medicine in the infusion bottle can fall and enter the human body;

[0059] The liquid detection unit 112 is detachably arranged on the pipeline 103 above the drip pot 102 in the infusion set, the liquid detection unit 112 is used to detect whether there is liquid in the pipeline 103, and sends a signal to the controller 111;

[0060] The controller 111 is used to receive the signal sent ...

Embodiment 2

[0083] The main difference between this embodiment 2 and the above-mentioned embodiment 1 is that in this embodiment, the automatic fluid exchange system is set on a commonly used double-headed infusion set.

[0084] like Figure 15 As shown, there are only two through holes 109-4 in the infusion control unit 108 in this automatic liquid exchange system, and there are only two infusion control mechanisms 110 corresponding to the through holes 109-4. The infusion process is the same as that in Embodiment 1. Similarly, when the liquid sensor 114 detects that the liquid medicine in the first medicine bottle 100-4 has been delivered, it will automatically switch to the medicine liquid in the second medicine bottle 100-5, thereby realizing the automatic replacement of the double-headed infusion set. Liquid and continuous infusion process.

[0085] It can be understood that for a double-head infusion set, only two through holes 109-4 and two corresponding infusion control mechanism...

Embodiment 3

[0087] In this embodiment, the infusion set also includes a liquid distribution bag 107. At this time, when the automatic liquid exchange system is installed on the infusion set, the liquid detection unit 112 needs to be arranged between the liquid separation bag 107 and the drip pot 102. On pipeline 103, such as Figure 16 shown.

[0088] In a further optimization scheme, the liquid detection unit 112 is arranged at a position close to the liquid distribution bag 107, so that when the liquid in the liquid distribution bag 107 has just been transfused, the liquid detection unit 112 can detect the signal immediately, even if the controller 111 Making timely and accurate follow-up control can prevent more air from entering the drip pot 102, causing the liquid level in the drip pot 102 to drop, which may affect the effect of the drip pot 102 on isolating air from entering the human body.

Abstract

The invention relates to an automatic liquid replacing system. The system comprises a controller, an infusion control unit and a liquid detection unit; the controller is connected to the infusion control unit and the liquid detection unit separately, wherein the infusion control unit is detachably arranged on an infusion apparatus and used for connecting or disconnecting a puncture pipe in a random puncture module in the infusion apparatus; the liquid detection unit is detachably arranged on a pipeline above a drip bulb in the infusion apparatus and used for detecting whether or not liquid exists in the pipeline and sending signals to the controller; the controller is used for receiving the signals sent by the liquid detection unit and controlling the infusion control unit to make puncturepipes in all puncture modules in the infusion apparatus connected or disconnected. The automatic liquid replacing system has the advantages of being simple in structure, low in cost, capable of recycled and the like, and can achieve automatic liquid replacing and continuous infusion processes of the infusion apparatus.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to an automatic liquid changing system. Background technique [0002] Infusion sets are commonly used medical devices for intravenous injection. Commonly used disposable infusion sets are usually divided into single-head infusion sets and double-head infusion sets. Among them, the basic structure of single-head infusion sets and double-head infusion sets The same, all consist of puncture module, drip pot, pipeline, flow regulator, liquid medicine filter and conical joint, wherein the puncture module includes puncture protection sleeve, puncture device, air filter, liquid stop clip and puncture tube; The single-head infusion set only contains one set of puncture modules, and the double-head infusion set contains two sets of puncture modules; in addition, some single-head infusion sets or double-head infusion sets also include a liquid distribution bag, which is usually set ...
