Description

Technical Field

[0001] The invention relates to the field of medical devices, and in particular to an infusion stand capable of heating liquid in an infusion bottle and a use method thereof. Background Art

[0002] In the cold seasons of autumn and winter, when hospitals infuse patients with infusions, the liquid in the infusion bottle is often relatively cold, which will cause some adverse reactions to the patient when it is injected into the patient's body. Since the temperature of the liquid in the infusion bottle is relatively low, it may cause the patient's body temperature to drop and blood vessels to contract when entering the human body, and the person being infused will feel uncomfortable. This situation is more obvious for the elderly and children. When infusion is needed in cold weather, many people will choose to use products such as warm baby or hot water bag to heat the liquid during infusion. Although it can increase the temperature of the liquid injected into the human body to a certain extent, it cannot achieve constant temperature infusion, and there are safety hazards such as insignificant effect and uncontrollable temperature. There are even cases of burns caused by sticking a warm baby on the arm. The cost of using a warm baby to heat the liquid is also high, and it is often in short supply. The liquid entering the patient's body is still cold, which cannot fundamentally solve the problem of the patient's discomfort during infusion. Due to the above problems, it is very necessary to preheat the liquid medicine to a temperature close to the human body and keep it in a warm environment for infusion, which is more practical for the elderly and children. Summary of the invention

[0003] The purpose of the present invention is to provide an infusion stand which can heat an infusion bottle at a constant temperature, and can heat the liquid to be infused into the body at a constant temperature when the weather is cold. The infusion stand can also be easily moved, thereby reducing the discomfort of patients receiving infusion in cold weather.

[0004] In order to solve the above technical problems, the present invention provides a constant temperature heating infusion stand, which features include: a rectangular outer shell on the upper part of the infusion stand, a force-bearing device for supporting the infusion bottle and the entire device, a heating device capable of heating the liquid medicine in the infusion bottle, a temperature sensor installed to monitor the actual temperature of the infusion liquid to ensure safety during infusion, a power supply device for the infusion stand system to supply power to the entire device for normal operation, a pressure sensor device used to solve the bottle change infusion and needle removal prompts during infusion, and a central processing unit device.

[0005] Furthermore, in order to realize that the heating device can smoothly heat the liquid medicine in the infusion bottle, its heating function is managed by a control system. The control system processes information through the main control chip, which receives feedback information from the temperature sensor and uses built-in algorithms and logic to adjust and control the temperature. A resistance wire is installed in the rectangular shell on the upper part of the infusion stand. This heating device is a resistance wire that heats the air to maintain a constant temperature in the shell space, thereby maintaining a constant temperature for the liquid in the infusion bottle. The heating device can reduce the discomfort of the patient during infusion.

[0006] Furthermore, in order to solve the safety problem of the device heating temperature, a temperature sensing device uses a temperature sensor to monitor the actual temperature of the infusion liquid. It can sense the temperature of the liquid and feed the information back to the control system. To ensure safety during infusion, we have safety control measures. By setting the temperature at 37 degrees, when the liquid temperature is heated to about 37 degrees, the heating device will stop working and maintain the temperature, so that the liquid entering the body is no longer cold, close to human body temperature, reducing the patient's discomfort. 37° constant temperature continuous output, the temperature will not fluctuate, and the power will be automatically cut off at high temperature. While enjoying comfortable infusion, you can also rest assured about safety issues.

[0007] Furthermore, in order to remind medical staff to perform infusion or remove needles in time, we install a pressure sensor device on the hook installed inside the circular shell to detect the approximate remaining amount of liquid in the bottle. When the remaining amount of liquid in the bottle is small, the pressure sensor will transmit a signal to the main control chip. At this time, the buzzer starts working and sounds an alarm to remind medical staff to change bottles for infusion or remove needles.

[0008] Furthermore, all sensors transmit data to the central processing system module, and the central processor analyzes the data transmitted by the sensors to issue operating instructions to various parts of the infusion stand, so as to achieve the purpose of constant temperature heating of the infusion stand. The power supply device supplies power to the central processing system module to realize the normal operation of the system. In order to facilitate the movement of the infusion stand, wheels are installed at the bottom so that nurses or patients can move it conveniently.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] When the temperature is low, the cold liquid may make the patient's already weak body even colder, forcing the patient to endure low-temperature infusion, increasing the patient's pain and annoyance. In addition, solid particles in the low-temperature liquid medicine are easy to precipitate in a low-temperature environment. When the solid particles reach a certain content, it is easy to cause vascular embolism. Our project can reduce this discomfort.

[0011] When the liquid is heated during infusion, the warm liquid will reduce the cold stimulation of the liquid on the human body and blood vessels, avoiding a series of infusion reactions such as body temperature drop or no rise, local pain and numbness, cramps, etc. During the infusion process, appropriate heating can ensure that the liquid medicine is fully dissolved and accelerated absorption, and can also improve the patient's mental state during the infusion process.

[0012] Experiments have shown that moderately warming the liquid has no adverse effect on the body temperature of fever patients. Infusing warmed liquid to patients can relieve upper respiratory symptoms such as nasal congestion and runny nose, increase comfort, and meet the requirements of humanized services. Cold temperatures cause patients to experience headaches or dizziness during infusion. For the elderly and those with poor physical fitness, infusion is extremely uncomfortable and painful. The temperature difference between the liquid medicine and the body temperature is more than ten degrees. It must be very uncomfortable to directly infuse into the body. If the cold liquid medicine enters our body for a long time, it will cause great harm to our body. Our project can effectively reduce the harm of low-temperature liquid infusion to the human body.
