Problems solved by technology

However, the transfusion automatic alarm of this structure, in the process of use, especially when there are more liquid medicines in the infusion bottle or the infusion bag, is subjected to the action of gravity, and the weight is disengaged from the position of the pulley, causing the transfusion automatic alarm to lose weight. unable to work properly
Furthermore, the automatic infusion alarm has three pulleys, and its overall structure is rather bulky, so it is easy to cause interference between two adjacent automatic infusion alarms in an infusion room with dense infusion locations.

Embodiment Construction

[0018] Below in conjunction with accompanying drawing, the present invention will be further described with specific embodiment, see Figure 1-Figure 2 ;

[0019] This embodiment provides a gravity infusion alarm including a fixed pulley 1 , a rope or belt 2 , a housing 3 , a weight 4 , an alarm trigger 5 and a limit device 6 . Wherein, the alarm trigger 5 can be a switch element, which is used to control the sounding device and / or the display device to make a corresponding prompt. When the weight 4 touches the alarm trigger 5, the sounding device and / or the display device make a corresponding prompt. In this way, medical personnel are reminded that the liquid medicine in the infusion bottle or the infusion bag is about to be finished.

[0020] see figure 1 , the housing 3 has a receiving cavity 31 for receiving the fixed pulley 1, the weight 4, the alarm trigger 5 and the limit device 6, and the weight 4, the alarm trigger 5 and the limit device 6 are all installed in the h...

Abstract

The invention discloses a gravity type transfusion alarm device. The device is suitable to be used for transfusion bottles or transfusion bags in different specifications, and the gravity type transfusion alarm device is ensured to operate normally. The gravity type transfusion alarm device comprises a fixed pulley. A rope object or a band object is hung on the fixed pulley. The first end of the rope object or the band object is fixedly provided with a weight. The second end of the rope object or the band object is used for hanging a transfusion bottle or a transfusion bag. The fixed pulley is rotatably fixed in a housing. The housing is also internally fixedly provided with an alarm trigger and a stop block. The weight is between the alarm trigger and the stop block. The alarm trigger is below the weight so the weight can touch the weight. The stop block is above the weight so that the weight can be abutted against the stop block. The distance between the alarm trigger and the stop block is larger than height of the weight. The gravity type transfusion alarm device can prompt in time when liquid amount in the transfusion bottle or the transfusion bag is low.

Description

technical field [0001] The invention belongs to the technical field of infusion alarms, in particular to a gravity type infusion alarm. Background technique [0002] In the medical field, many diseases need to be treated through infusion. During the infusion process, it is necessary to keep an eye on the remaining liquid volume in the infusion bottle or infusion bag. However, in the infusion process, it is inevitable that the drug solution in the infusion bottle or the infusion bag cannot be found in time because of inattentiveness or falling asleep. [0003] At present, there is an infusion alarm, which can prompt in time that the liquid medicine in the infusion bottle or the infusion bag is about to be finished. For example, the Chinese invention patent whose publication number is CN201930314U and whose publication date is August 17, 2011 discloses an automatic infusion alarm. The infusion automatic alarm has a tripod, and a pulley is respectively arranged at the three ...
