Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to an infusion alarm. Background Art
[0002] Intravenous infusion is one of the commonly used treatment methods in clinical practice. When a patient receives an infusion in the hospital, he or she usually needs care from a nurse or family member. When the infusion is finished, medical staff need to remove the needle or change the dressing in time to avoid blood backflow in the infusion line or accidentally injecting air into the blood vessel, causing unnecessary harm.
[0003] For example, Chinese patent: Publication No. CN210277891U discloses an infusion alarm. An infusion alarm includes: a box body; a fixing plate, the fixing plate is fixed between the two sides of the inner wall of the box body; a lifting plate, the lifting plate slides between the two sides of the inner wall of the box body; a hanging rod, the surface of the hanging rod is arranged at the bottom of the box body, the top of the hanging rod passes through the top of the box body and the bottom of the fixing plate in sequence and extends to the top of the fixing plate; a hanging ring, the top of the hanging ring is fixed to the bottom of the hanging rod.
[0004] Although the infusion alarm provided by the utility model has an adjustable lifting plate that can adjust the load-bearing and alarm quality of the hanging ring, and is suitable for infusion bottles of different sizes, it is more practical, and the early alarm can remind patients and medical staff to change the infusion or remove the needle in time, avoiding unnecessary harm caused by the medical staff not having enough time to change the infusion and remove the needle when the dose in the infusion bottle is too much, thereby reducing the work pressure of the medical staff and improving the safety and reliability of the alarm. However, the device cannot detect and alarm the bubble situation inside the infusion tube. When bubbles enter the lower infusion tube, if the bubbles cannot be discharged in time, too many bubbles will enter the patient's blood vessels, thereby causing adverse effects on the patient.
[0005] To this end, we proposed an infusion alarm. Utility Model Content

[0018] (III) Beneficial effects
[0019] The beneficial effects of the utility model are:
[0020] 1. Through the measurement components that are set up, use the connecting frame to connect the sensing surface of the pressure sensor to the upper surface of the expansion membrane. When bubbles enter the lower infusion tube, the bubbles flow through the side tube. Due to the influence of density, they will float along the side tube to the inside of the gas collecting tube. Under the action of pressure, the expansion membrane is pushed to expand, so that the sensing surface of the pressure sensor receives the pressure, which is then transmitted to the terminal of the nurse station for alarm, so that the nurse can check the situation in time and prevent bubbles from entering the patient's blood vessels and causing adverse effects on the patient.
[0021] 2. Through the setting of the adjustment component, infrared sensor and infrared receiver, when there is medicine in the medicine bottle, it is hung on the hook, and the spring is pulled down under the action of gravity to make the protective frame separate from the box. At this time, the infrared receiver can normally receive the light waves emitted by the infrared sensor. When the medicine in the medicine bottle is delivered, the spring contracts and drives the protective frame to slide into the box under the action of the limit plate, thereby blocking the light waves emitted by the infrared sensor. At this time, the infrared receiver cannot receive the light waves and alarms, which is convenient for medical staff to change the infusion and remove the needle. BRIEF DESCRIPTION OF THE DRAWINGS

In the actual implementation process, first, the device is hung on the infusion stand as a whole through the connecting ring 8, and then the hanging ring 501 is hung on the hook 204, and the medicine bottle 502 is connected to the protective frame 202. Then, when there is liquid medicine in the medicine bottle 502, the spring 201 is pulled down under the action of gravity, so that the protective frame 202 is separated from the box body 1. At this time, the infrared receiver 4 can normally receive the light waves emitted by the infrared sensor 3. Secondly, when the liquid medicine in the medicine bottle 502 is delivered, the spring 201 contracts, driving the protective frame 202 to slide to the box body under the action of the limit plate 203. 1, thereby blocking the light waves emitted by the infrared sensor 3. At this time, the infrared receiver 4 cannot receive the light waves and gives an alarm. Finally, the connecting frame 704 is used to connect the sensing surface of the pressure sensor 705 with the upper surface of the expansion membrane 703. When the bubble enters the lower infusion tube 603, the bubble flows to the side tube 701. Due to the influence of density, it will float up to the inside of the gas collecting tube 702 along the side tube 701. Under the action of pressure, the expansion membrane 703 is pushed to expand, so that the sensing surface of the pressure sensor 705 receives the pressure, which is then transmitted to the terminal of the nurse station to give an alarm.

In the actual implementation process, when there is liquid medicine in the medicine bottle 502, it is hung on the hook 204, and the spring 201 is pulled down under the action of gravity to make the protective frame 202 separate from the box body 1. At this time, the infrared receiver 4 can normally receive the light waves emitted by the infrared sensor 3. After the liquid medicine in the medicine bottle 502 is transported, the spring 201 contracts, driving the protective frame 202 to slide to the inside of the box body 1 under the action of the limit plate 203, thereby blocking the light waves emitted by the infrared sensor 3. At this time, after the infrared receiver 4 cannot receive the light waves, an alarm is issued, which is convenient for medical staff to replace the infusion and remove the needle.

When bubbles enter the lower infusion tube 603, the bubbles flow to the side tube 701, and under the influence of density, they will float up to the inside of the gas collecting tube 702 along the side tube 701, and push the expansion membrane 703 to expand under the action of pressure, so that the sensing surface of the pressure sensor 705 receives pressure, which is then transmitted to the terminal of the nurse station for alarm, so that the nurse can check the situation in time and prevent the bubbles from entering the patient's blood vessels and causing adverse effects on the patient.
