Embodiment 1

[0034] like Figure 1-4 As shown, the continuous infusion device of this embodiment includes a bottle stopper puncture part 1 , an automatic channel switching device 2 , a dropping funnel 3 and an infusion needle 4 along the flow path in sequence.

[0035] The cork piercer 1 includes a first cork piercer 11 and a second cork piercer 12, and the channel automatic switching device 2 includes a water outlet pipe 23, a first infusion channel 211 and a second infusion channel 212, so The water outlet pipe 23 communicates with the dropping funnel 3 .

[0036]The tops of the first and second infusion channels 211 and 212 are respectively provided with first and second medical solution inlets 221 and 222 , and the infusion channels communicate with corresponding bottle stopper piercers through corresponding drug solution inlets.

[0037] The first infusion channel 211 and the second infusion channel 212 are connected through a communication isolation component 25 . The communication...

Embodiment 2

[0046] Embodiment 1 has a relatively inconvenient design, that is, it is necessary to install ring magnets one by one after pouring the liquid medicine into the infusion channel, which is troublesome and complicated to operate. In order to overcome this shortcoming, we improve on the basis of embodiment 1.

[0047] like Image 6 and 7 As shown, in the first infusion channel 211 in this embodiment, the setting of the support spring 2111 is cancelled, the ring magnet 27 is fixedly arranged at the bottom of the first infusion channel 211, and the suspension part 28 is fixedly arranged above the float. The suspension part 28 is provided with a suspension rod 281, which is located on the central axis of the first infusion channel 211 and is vertically downward. The bottom of the suspension rod 281 is symmetrically connected to the support rod 282, the bottom of the support rod 282 is connected to the bottom side wall of the suspension rod 281, and the top is a free end. The conn...

Abstract

The invention relates to a magnetic continuous infusion apparatus capable of sequentially switching channels, which sequentially comprises a bottle stopper puncture part, an automatic channel switching device, a drip chamber and an infusion needle along a flow path, a water outlet pipe and a plurality of cylindrical infusion channels are arranged in the automatic channel switching device, and the water outlet pipe is communicated with the drip chamber. According to the continuous infusion apparatus, infusion channels are sequentially switched according to priorities during infusion under the action of buoyancy, gravity and magnetic force. According to the continuous infusion apparatus, the infusion channels can be sequentially switched according to the priorities during infusion, after infusion of the liquid medicine corresponding to the current infusion channel is completed, the acupuncture assembly punctures the isolation film under the action of gravity and magnetic force, infusion of the liquid medicine corresponding to the infusion channel of the next priority is automatically started, the medicine liquid corresponding to the infusion channel with the lowest priority is completely infused. According to one embodiment of the invention, due to the arrangement of the suspension release structure, the isolation film can be prevented from being punctured accidentally in the transportation process under the condition that the function is realized.

Description

technical field [0001] The present invention relates to an intravenous infusion device, more particularly, to a continuous infusion device with acupuncture-type sequentially switching channels. Background technique [0002] The intravenous infusion set is a commonly used device in clinical treatment. The basic structure includes a cork piercer, an air inlet / exhaust device, a drip funnel, a liquid medicine filter, and an infusion needle. Road, the liquid into the patient's vein. In many cases, patients need continuous infusion of multiple medical solutions, which cannot be mixed and must be infused in a certain order. This requires the nursing staff to continuously monitor the infusion progress of the medicinal solution and replace the medicinal solution in time, which is time-consuming and laborious, and may easily lead to medical accidents. [0003] In order to solve this problem, some researchers have developed an intravenous infusion set that can automatically infuse me...
