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] The present invention will be further described below with specific embodiments in conjunction with the drawings, see Figure 1-Figure 2 ;

[0019] This embodiment provides a gravity type infusion alarm including a fixed pulley 1, a rope or ribbon 2, a housing 3, a weight 4, an alarm trigger 5 and a limit device 6. Wherein, the alarm trigger 5 may be a switch element for controlling the sounding device and / or the display device to make corresponding prompts. When the weight 4 touches the alarm trigger 5, the sounding device and / or the display device make corresponding prompts. In this way, the medical staff is 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 housing 3 within.

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, and specifically relates to a gravity type infusion alarm. Background technique [0002] In the medical field, many diseases need to be treated by infusion. During the infusion process, always pay attention to the amount of liquid left in the infusion bottle or infusion bag. However, it is inevitable that during the infusion process, carelessness or falling asleep will inevitably lead to failure to find that the infusion bottle or infusion bag has been infused in time. [0003] Currently, there is an infusion alarm, which can promptly prompt that the liquid medicine in the infusion bottle or the infusion bag is about to be infused. For example, a Chinese invention patent with publication number CN201930314U and publication date on August 17, 2011 discloses an automatic infusion alarm. The automatic infusion alarm has a tripod, each of the three vertices of the tripod is provided with a pulley...
