Abstract
Description
Technical Field
[0001] The utility model relates to the field of medical infusion, in particular to a wireless infusion metering and monitoring device. Background Art
[0002] Intravenous infusion is a common medical treatment method. During infusion, patients, family members or medical staff are often required to monitor the infusion status in real time. At the same time, nurses need to use their rich clinical treatment experience to adjust the flow rate of intravenous infusion to ensure that the patient has normal infusion and no discomfort. However, if the patient falls into a coma during the infusion process and the accompanying family members and medical staff fail to discover it in time, it is easy to cause abnormal infusion conditions, infusion flow rates exceeding the standard, blood reflux through the infusion tube, etc. In more serious cases, a serious medical accident will occur.
[0003] Most of the existing infusion monitoring devices need to be connected to a power cord for power supply and are bulky. It is often necessary to provide an additional bracket to fix the infusion monitoring device in order to realize the infusion monitoring function. The existing devices only provide a display screen on the outer shell of the device to display the recorded data and cannot realize wireless data transmission. In addition, although the capacitive infusion monitoring device is relatively small, it can only identify whether there is liquid passing through the sensing area and cannot accurately measure the volume of the infused liquid; the weighing infusion monitoring device has the problem of poor stability during the weighing and measuring process, which easily leads to errors in the transmission process. These infusion monitoring devices have the disadvantages of being large in size, susceptible to interference, low in precision, difficult to calibrate, complicated to operate, and unable to transmit data wirelessly in real time.
[0004] Therefore, the present application proposes a wireless infusion metering and detection device that will effectively improve medical efficiency, solve various shortcomings of the current existing technology, and realize real-time monitoring and accurate metering of infusion liquids.

[0029] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0030] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0031] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the utility model. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.
[0032] Unless otherwise specifically stated, the relative arrangement of the parts and steps described in these embodiments, numerical expressions and numerical values do not limit the scope of the utility model. At the same time, it should be clear that, for ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The technology, methods and equipment known to ordinary technicians in the relevant field may not be discussed in detail, but in appropriate cases, the technology, methods and equipment should be regarded as a part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.
[0033] In the description of the present utility model, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present utility model and simplifying the description. Unless otherwise stated, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present utility model: the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.
[0034] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below their position devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.
[0035] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the utility model.

The sensor 8 is located on both sides of the upper end of the Murphy's dropper 7; the sensor 8 monitors whether there is a drop of liquid falling in its sensing area, and when the liquid passes through the sensing area of the sensor 8, a sensing signal change will be generated and transmitted to the control chip.
[0037] An observation window 5 is provided on the back of the first housing 1, and a data copy port 6 is provided at the lower corner of the inner side of the first housing 1. The device user can observe the flow rate in the Murphy's dropper 7 through the observation window 5.
