Abstract
Description
Technical Field
[0001] This utility model belongs to the field of monitoring and alarm technology, specifically an infusion monitoring and alarm device. Background Technology
[0002] In medical practice, intravenous infusion is a common and important treatment method, widely used in the treatment of various diseases. However, the infusion process requires strict monitoring to prevent unexpected situations such as the infusion running out or the infusion tubing becoming blocked. These unexpected situations may not only lead to treatment interruption but also cause unnecessary pain and harm to the patient.
[0003] A search revealed that in a utility model publication with publication number CN216934288U, an infusion monitoring and alarm device is disclosed. This device includes a housing, a spring clip on the top surface of the housing, an infusion tube held within the inner wall of the spring clip, a motor fixedly mounted on the back of the housing, a threaded column fixedly connected to the motor's output end, a cavity inside the left side wall of the housing, and the surface of the threaded column rotatably connected to the inner wall of the cavity via a bearing, a threaded sleeve threadedly connected to the surface of the threaded column, a connecting rod fixedly connected to the right side of the threaded sleeve, a clamping block fixedly connected to the surface of the connecting rod, a sliding groove on the inner wall of the housing, and a flow sensor located on the left side of the inner wall of the housing.
[0004] The aforementioned infusion monitoring and alarm device effectively reminds patients and medical staff to pay attention to the infusion volume in a timely manner, facilitating precise control of the infusion flow rate and reducing the burden on medical staff and patients, making the entire infusion process easier and more convenient. However, some problems still exist in its practical use:
[0005] The aforementioned infusion monitoring and alarm device is installed by clamping the infusion tubing with a spring clip. However, the weight of the device itself can easily cause the infusion tubing to detach from the infusion bottle. Furthermore, when the device is connected to the infusion tubing via the spring clip, the device itself is not in close contact with the infusion tubing when the alarm is not triggered, which can easily lead to detection errors and false alarms.
[0006] Therefore, an infusion monitoring and alarm device is proposed to address the above problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0028] Specific implementation examples are given below.
[0029] Please see Figures 1-5 This utility model provides a technical solution: an infusion monitoring and alarm device, including a first device body 1, a second device body 2 movably connected to the rear of the outer surface of the first device body 1, and the second device body 2 has the same structure as the first device body 1. A connector 3 is fixedly connected to the upper part of the first device body 1, and irregularly shaped clamping grooves 4 are opened in the middle of the right side of the first device body 1 and the middle of the left side of the second device body 2. The two irregularly shaped clamping grooves 4 are mirror images of each other. Charging holes 5 are opened at the bottom of the first device body 1 and the bottom of the second device body 2. Three equally spaced levers 6 are fixedly connected to the front of the outer surface of the first device body 1 and the front of the outer surface of the second device body 2. A set of magnetic blocks 7 are fixedly connected to the front of the right side of the first device body 1 and the front of the left side of the second device body 2, and the two sets of magnetic blocks 7 are magnetically connected to each other.
[0030] Furthermore, such as Figures 1-5 As shown, the connector 3 includes a fixing base 31, which is fixedly connected to the upper end face of the first device body 1. A fixing rod 32 is fixedly connected to the upper part of the fixing base 31, and a retaining ring 33 is fixedly connected to the upper part of the fixing rod 32. The retaining ring 33 is located on the upper part of the irregular clamping groove 4. An infrared sensor module 101 and a central control board 102 are provided on the upper side inside the second device body 2. The monitoring end of the infrared sensor module 101 is flush with the inner surface of the irregular clamping groove 4. A buzzer 104 and two control buttons 103 are provided on the upper part of the second device body 2. The buzzer 104 and the two control buttons 103 do not contact the connector 3. A flashing light 105 is fixedly connected to the upper part of the outer surface of the second device body 2.
[0031] The above solution involves fixing a connector 3 to the upper part of the main body 1 of the first device. When the device is in use, the connector 3 can be engaged with the neck of the infusion bottle to prevent the weight of the device itself from causing the infusion tube to fall off the infusion bottle, thereby improving the safety of the device during use.
[0032] Furthermore, such as Figure 1 , Figure 2 and Figure 5As shown, a heating module 111 and a battery 113 are provided on the lower side of the inner side of the main body 2 of the second device. A heating wire 112 is fixedly connected to the lower side of the heating module 111, and the outer surface of the heating wire 112 is in contact with the inner surface of the irregular clamping groove 4. Multiple heat dissipation holes 114 are provided on the lower part of the outer surface of the main body 2 of the second device. The battery 113 is located on the side close to the multiple heat dissipation holes 114 and is electrically connected to the charging hole 5.
[0033] The above solution involves installing heating components on the lower side of the interior of both main bodies of the device. When the device is used in cold weather, the heating module 111 can be controlled by the control button 103 to work, so that the heating wire 112 can emit heat to heat the infusion solution in the infusion tube inside the irregular clamping groove 4, thereby improving the patient's comfort during infusion.
[0034] Working principle: First, connect the connector 3 in the device to the neck of the infusion bottle. Then, unfold the two main body of the device and screw the infusion tubing coil into the irregular clamping groove 4 in one of the main body of the device. Then, close the two main body of the device and start the device by pressing the control button 103. During use, the infrared sensor module 101 will monitor the flow of the medicine inside the infusion tubing in real time. When it detects that there is no flow of medicine inside the infusion tubing for a certain period of time, the infrared sensor module 101 will send a signal to the central control board 102. 2. Simultaneously control the buzzer 104 and flashing light 105 to alert staff and patients. When the device is used in cold weather, the heating module 111 can be controlled by the control button 103 to heat the heating wire 112 to heat the infusion solution in the infusion tube inside the irregular clamping groove 4, which can improve the patient's comfort during infusion. At the same time, multiple heat dissipation holes 114 are provided on the outside of the main body of the device and are connected to the internal storage battery 113 to dissipate heat from the storage battery 113 and prevent the heating wire 112 from affecting the storage battery 113 when it is working.
