The invention will be further explained with reference to the drawings:

fig. 1 is a schematic structural diagram of the present invention.

Fig. 2 is a schematic diagram of the circuit connection structure of the present invention.

Fig. 3 is a rear view of the present invention.

In the figure: the anti-theft lock comprises a shell 1, a fixing rod 2, a spring 3, a conducting rod 4, a hook 5, a single-pole multi-throw switch 6, an indicator light 7, a buzzer 8, a hanging ring 9, a battery box 10, a charging interface 11 and an anti-theft lock 12.

Detailed Description

As shown in fig. 1 to 3, a gravity type automatic transfusion alarm comprises a housing 1, wherein a fixed rod 2 is fixedly connected inside the housing 1, a conductive rod 4 is suspended on the fixed rod 2 through a spring 3, and a hook 5 is fixedly connected below the conductive rod 4;

the inside warning circuit that is equipped with of shell 1, warning circuit include power module, and power module is connected with warning module, and warning module is connected with single-pole multi-throw switch 6, and the warning circuit branch road of co-altitude not is connected respectively to single-pole multi-throw switch 6's different contacts, and the warning circuit branch road connects back to power module through conducting rod 4.

Referring to fig. 1 and 2, a single-pole double-throw switch is selected as an example, the specifications of common infusion bottles are 500ml and 250ml, which respectively correspond to 1 gear and 2 gears of the single-pole double-throw switch, when the 500ml infusion bottle is adopted, the switch is shifted to 1 gear, the total weight of the drug bottle can be gradually reduced along with the gradual entry of the drug liquid into the body of a patient, when the drug liquid is about to be infused, a conducting rod connected with a spring is raised to the same height of a warning circuit branch corresponding to the 1 gear, the whole warning circuit with the 1 gear is switched on, and a warning module sends out an alarm to remind the patient that medical staff is called to change the drug or pull out the needle. When a 250ml infusion bottle is adopted, the switch is switched to the 2-gear, and at the moment, the 1-gear warning circuit branch is disconnected at the position of the single-pole double-throw switch, so that when the conducting rod rises to the same height of the 1-gear corresponding warning circuit branch, the whole circuit cannot be connected. When the conducting rod rises to the same height of the corresponding warning circuit branch of the 2 grades, the warning module gives an alarm. When the alarm is turned off, the switch is only required to be shifted to the 0 gear, and the operation is simple and convenient.

In a preferred scheme, the warning module is an indicator light 7, and the indicator light is arranged on the shell 1.

In practice, the warning module is not limited to the indicator light and the buzzer, but there are many other alternatives such as a music player set in advance, etc. Various warning devices may also be used in combination, e.g. with both devices

In a preferred scheme, a hanging ring 9 is arranged above the shell 1. The rings facilitate the alarm to be hung on a transfusion frame, so that the alarm can work normally.

In a preferred scheme, the power supply module is arranged in a battery box 10, and the battery box 10 is arranged on the shell 1.

In a preferred scheme, the power module is a rechargeable battery, and a charging interface 11 is arranged on the battery box 10.

In a preferred scheme, the power supply module is a dry battery.

The rechargeable battery can be used repeatedly, has little influence on the environment, but needs to be charged frequently; the dry battery does not need to be charged, can be used for a long time when being installed, but needs to be replaced when being used up. When in use, a more suitable power supply module is selected according to the actual situation.

In a preferred scheme, an anti-theft lock 12 is further connected to the shell 1. The alarm can be locked on the infusion support by the anti-theft lock.

In a preferred scheme, the conductive rod 4 is a copper rod with the diameter of 1 cm. The copper has good conductivity, and the alarm can continuously give an alarm within a period of time due to the arrangement of a certain thickness, so that the effect of finding a copper rod with the diameter of 1cm is better in practical use.
