AI Technical Summary
In the existing infusion system, patients need to observe the fluid level by themselves, which is prone to distracting, resulting in failure to notify the nurse in time after the infusion is completed, causing the risk of missed injections.
Design an infusion plate with an alarm device, using a mechanical structure of springs and conductive contacts. When the liquid in the infusion bottle is reduced to a set amount, the spring shrinks and triggers the conductive contacts, forming an electrical circuit, and the alarm light and alarm emit an alarm to remind the patient or nurse.
The automatic alarm function is realized, reducing the risk of patients observing the fluid level by themselves, ensuring that the nurse can be notified in a timely manner after the infusion is completed, and avoiding missed accidents.

[0001] The utility model relates to an infusion plate with an alarm device. [Background technology]
[0002] Infusion therapy is a commonly used treatment method in clinical practice. Currently, the infusion bottle is hung on the infusion stand, and then connected to the infusion tube for infusion. At the same time, the infusion sheet is clipped on the infusion board and hung on the infusion stand. At present, most patients need to observe the liquid level by themselves and notify the nurse when the infusion is completed. However, people are often distracted, and it is common that the infusion is completed but the nurse is not notified before the needle is removed.

[0021] The utility model is further described below in conjunction with the accompanying drawings:
[0022] like Figures 1 to 6 As shown, an infusion board with an alarm device includes an infusion board body 1, on which a spring cavity 10, an electric control box 2 with a built-in power supply battery and an alarm light 3 electrically connected to the power supply battery are provided. A spring 4 is provided in the spring cavity 10, one end of the spring 4 is fixed in the spring cavity 10 and electrically connected to the alarm light 3, and the other end of the spring 4 is provided with a first hook 41 extending out of the spring cavity 10 and used to hang an infusion bottle. A conductive contact 5 protruding toward one side of the spring 4 is provided on the inner side wall of the spring cavity 10, and a control switch 6 for controlling the conductive connection between the power supply battery and the conductive contact 5 is provided on the electric control box 2. A conductive part 42 that moves with the expansion and contraction of the spring and can be connected to the conductive contact 5 is provided on the spring 4. When the control switch 6 is turned on and the liquid in the infusion bottle is reduced to a set amount, the spring 4 contracts to make the conductive part 42 conductively connected to the conductive contact 5, thereby forming an electrical circuit to energize the alarm light 3. Since the commonly used dissolving agent in the current infusion is physiological sodium chloride solution, and then the drug for treating the disease is added to the sodium chloride liquid, the density of each bottle of injection is close to the density of the physiological sodium chloride solution, and the weight of the injection per unit volume can be basically determined. Moreover, when a spring with a known elastic coefficient is selected to hang the infusion bottle, the elastic force of the spring is equal to the gravity of the infusion bottle, and the relationship between the deformation of the spring and the volume of the injection can be determined. According to this relationship, the position of the conductive contact 5 corresponding to the conductive part 42 when the liquid is reduced to a set amount can be determined experimentally. The utility model adds a simple device on the infusion board. When the infusion is about to reach a predetermined amount, due to the reduction in the weight of the infusion bottle, the conductive part 42 on the spring 4 inside the device triggers the conductive contact 5 pre-set on the inner wall of the spring cavity 10, resulting in power-on, causing the alarm light 3 to flash, reminding the patient to pay attention to turning off the infusion device or notifying the nurse.
[0023] Further, a plurality of conductive contacts 5 are provided and are arranged on the inner side wall of the spring cavity 10 at intervals along the extension direction of the spring 4. A plurality of control switches 6 are provided corresponding to the conductive contacts 5 one by one, and the plurality of control switches 6 are connected in parallel. Specifically, the control switch has various modes of 0ml, 50ml, 100ml, 250ml and 500ml to select. When the main switch 13 is turned on and the control switch 6 corresponding to the set mode is selected, when the infusion is reduced to a corresponding volume, the conductive part 42 contacts the corresponding conductive contact 5 for conduction, thereby forming an electrical circuit to energize the alarm light 3, and the alarm light 3 flashes.
[0024] Furthermore, at least the front side of the infusion board body 1 is a light-transmitting surface, and a non-ultraviolet LED white light lamp 7 is provided inside the infusion board body 1, which is electrically connected to the power supply battery and can emit white light through the light-transmitting surface to illuminate the infusion bottle. When the main switch 13 is turned on, the non-ultraviolet LED white light lamp 7 will light up, so that the non-ultraviolet LED white light source forms a bright background through the white plastic plate, so that the nurse can clearly observe the liquid properties of the infusion bottle, avoid infusing the liquid containing impurities or crystals to the patient, avoid medical disputes, and clearly observe the liquid plane of the infusion bottle, and the white background light can be used as a night light, which provides convenience for night infusion without affecting the patient's rest.
[0025] Furthermore, an alarm 8 is provided on the infusion board body 1, which can emit an alarm sound when the alarm light 3 is powered on. When the alarm light 3 is on, the alarm 8 emits an alarm sound and reminds at the same time.
[0026] Specifically, the infusion plate body 1 includes a light-transmitting bottom plate 11 and a light-transmitting panel 12 that cooperates with the light-transmitting bottom plate 11 and encloses a cavity. The electric control box 2, the alarm light 3 and the alarm 8 are arranged in the cavity. The spring cavity 10 is arranged on the outside of the light-transmitting panel 12. A spring cavity cover is provided on the spring cavity 10. The spring cavity cover cooperates with the spring cavity wall to clamp one end of the spring 4.
[0027] In order to facilitate hanging of the device, a second hook 9 for hanging on an infusion stand is provided at the upper end of the infusion board body 1 .
