Example Embodiment

[0022] Example 1, the external signal plug is connected as Figure 4 The signal receiving circuit in the single-channel wired alarm device shown:

[0023] When the external signal plug is connected to a single-channel wired control alarm device composed of a signal receiving circuit, a signal amplifying circuit and a loudspeaker alarm circuit, an automatic alarm for a single bed can be realized. The process is: during the infusion process, the ring-shaped conductive electrodes 10 at the upper and lower ends of the liquid level controller 3 are conducted through the liquid medicine, and when the liquid medicine in the upper infusion tube 2 is lower than the liquid level controller 3 When the upper ring-shaped conductive electrode 10 is open, the two electrodes are disconnected, and the external alarm device receives a signal to alarm, and informs the attendant to ask the medical staff to come for treatment. This alarm mode is suitable for infusion patients accompanied by personnel....

Example Embodiment

[0024] Embodiment 2, the external signal plug is connected as Figure 5 The transmitter in the multi-channel wireless control alarm device shown:

[0025] When the external signal plug is connected to a transmitter composed of a signal receiving circuit, a signal amplifying circuit and a frequency-selective transmitting circuit, the self-alarm for multiple beds can be realized. The process is: during the infusion process, the ring-shaped conductive electrodes 10 at the upper and lower ends of the liquid level controller 3 are conducted through the liquid medicine, and when the liquid medicine in the upper infusion tube 2 is lower than the liquid level controller 3 When the upper ring-shaped conductive electrode 10 is open, the two electrodes are disconnected, the external transmitter receives the signal, and selects the frequency to transmit, and the transmitted signal is received by the signal receiving circuit, the signal amplifying circuit and the speaker alarm circuit set in th...

Abstract

The invention discloses a transfusion system with alarming function. The production method comprises: arranging a sealed small ball whose diameter is bigger than the lower outlet of Murphy burette inside the Murphy burette of former transfusion system, while the lower part of said transfusion system has a liquid level controller which via the plug is connected to the signal receiving circuit of wire single-channel control alarm device or wireless multi-path control alarm device; or the production method comprises: arranging a safe control pipe on the lower transfusion pipe of former transfusion system while a sealed small ball whose diameter is bigger than the lower outlet of safe control pipe arranged in said control pipe, and said lower part of transfusion pipe has a level liquid controller which via the plug is connected to the signal receiving circuit of wire single-channel control alarm device or wireless multi-path control alarm device. Compared to present technique, said invention can support enough time to the medical staff and the transfusion safe of sicker.

Description

technical field [0001] The invention relates to a medical device, more specifically, the invention relates to an infusion set which can alarm. Background technique [0002] As everyone knows, when using an existing infusion set to infuse a patient, it is often necessary for the escort or the patient to pay attention to whether the medicinal solution in the infusion tube is dripped out. Otherwise, in case the liquid medicine in the upper part of the Murphy dropper drips out, the air will follow the liquid medicine in the lower part of the Murphy dropper into the infusion tube, and even enter the patient's body. Like this, not only can bring misery to the patient, and will continue to infuse, also must exhaust air again, or change new transfusion tube etc., thereby cause some troubles of medical care work. For special patients who are not suitable for escorts such as infectious diseases, it increases the tension of patients and the workload of ...
