A heat-insulating sponge is fixedly connected to the inner wall of the cylindrical outer shell, and a sleeve fixing component is fixedly connected to the outer wall of the circular main rod. This blood transfusion and infusion device with good heat preservation effect differs from traditional blood transfusion and infusion devices. Through the use of a heat preservation structure, this device can effectively reduce the rate of temperature drop of the fluid during blood transfusion and infusion, maintain the stability of the fluid temperature, thereby improving patient comfort. Furthermore, the convenient installation structure brings convenience to medical staff and improves the safety of blood transfusion and infusion. Therefore, it has significant practical value and promotional significance.

[0005] The aforementioned patent achieves the function of keeping the medicine liquid warm through the setting of the heat preservation structure, which improves the comfort of infusion in winter. However, the device needs to be moved to adjust the position of the infusion, and the amount of medicine left in the bottle needs to be checked at any time during the infusion to facilitate needle removal, which makes the work of medical staff cumbersome. Therefore, it is of great significance to set up an infusion device that can monitor the liquid volume and adjust the position of the infusion bottle. Utility Model Content

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, 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.

[0026] Example

[0027] like Figures 1-4 As shown, a multifunctional infusion device includes a U-shaped slide rail 100, which is horizontally arranged. Both ends of the U-shaped slide rail 100 are fixed to the wall above the head of the hospital bed. A sliding component 300 is slidably installed on the U-shaped slide rail 100. A telescopic rod 400 is installed at the lower end of the sliding component 300. An infusion box 200 is fixedly connected to the bottom of the telescopic rod 400.

[0028] The infusion box 200 includes a barrel 210. A groove 240 is provided on the lower inner wall of the barrel 210 to engage with the mouth of the infusion bottle. A spiral heating tube 250 is installed on the inner wall of the barrel 210. Multiple sensors 260 are installed in the groove 240. The spiral heating tube 250 and the multiple sensors 260 are all electrically connected to the controller.

[0029] The infusion box 200 is connected to the telescopic rod 400 so that it is hung on the sliding member 300. Through the sliding cooperation between the sliding member 300 and the U-shaped slide rail 100, the position of the infusion box 200 under the U-shaped slide rail 100 can be adjusted to facilitate the operation of medical staff.

[0030] When intravenous infusion is required, the infusion bottle is inverted inside the container 210, and the bottle opening is aligned with the groove 240 for fastening. First, the infusion needle on the infusion tubing is inserted into the bottle opening, and then the infusion outlet needle of the infusion tubing is connected to the patient to begin infusion. At this time, the sensor probe is in contact with the bottom of the infusion bottle for easy measurement. If the temperature of the infusion solution is felt to be low during infusion, the spiral heating tube 250 can be driven by the controller to heat it to a suitable temperature to reduce patient discomfort.

[0031] In this embodiment, the plurality of sensors 260 include temperature sensors and liquid level sensors.

[0032] Specifically, the liquid level sensor is a capacitive liquid level sensor, and the temperature sensor is a resistive temperature sensor. The temperature sensor monitors the temperature of the medication solution, and the temperature data is transmitted to the controller. Based on the temperature data, the controller can determine whether the medication solution needs to be heated. When heating is required, it drives the spiral heating tube 250 to heat the solution until the appropriate temperature is reached, thus reducing patient discomfort. The liquid level sensor monitors the flow rate. When the medication infusion is about to be completed, the liquid level sensor will promptly sound an alarm to notify medical staff to remove the needle or replace the empty infusion bottle with the next bottle of medication, reducing the workload of staff.

[0033] It should be noted that the controller is a PLC controller, which can adjust parameters and has a display screen to show various data such as drug temperature and fluid flow. The controller is installed on the side of the bed for easy operation by doctors.

[0034] In this embodiment, the bottom of the U-shaped slide rail 100 is provided with a first groove 110, and a rack 120 is provided on one side wall of the U-shaped slide rail 100 located in the first groove 110. The top of the U-shaped slide rail 100 is provided with a second groove 130, and a sliding groove 140 is connected between the first groove 110 and the second groove 130. A motor 310 is fixedly installed on the top of the sliding member 300, and a telescopic rod 400 is fixedly installed on the bottom of the sliding member 300. The motor 310 is electrically connected to the controller, and the output shaft of the motor 310 passes downward through the sliding groove 140 and is fixedly connected to a gear 320. The gear 320 is located in the first groove 110, and the gear 320 meshes with the rack 120.

[0035] Driven by the motor 310, the sliding member 300 engages with the gear 320 and the rack 120, causing the sliding member 300 to slide on the U-shaped slide rail 100. The rotation of the motor 310 is controlled by the controller, reducing the inconvenience of movement for medical staff. It should be noted that the motor 310 can rotate in both forward and reverse directions, and the sliding member 300 is relatively narrow, allowing it to pass smoothly through the curved area of ​​the U-shaped slide rail 100.

[0036] In this embodiment, the upper end of the outer wall of the barrel 210 is also provided with a plurality of mounting ear plates 220. The plurality of mounting ear plates 220 are evenly distributed on the barrel 210 and located at the same height. A pull strip 230 is fixed on the mounting ear plate 220. The ends of the plurality of pull strips 230 away from the mounting ear plate 220 are all fixedly connected to the bottom of the telescopic rod 400.

[0037] In this embodiment, the telescopic rod 400 is an electric telescopic rod, and the telescopic rod 400 is electrically connected to the controller.

[0038] The telescopic pole 400 is an electric telescopic pole, and its height can be adjusted via a controller, making it convenient for medical staff to put in and take out infusion bottles.

[0039] In this embodiment, the controller is electrically connected to an alarm.

[0040] In this embodiment, the barrel 210 is a visible transparent barrel.

[0041] The transparent container allows doctors to see the remaining liquid level and also view the name of the fluid entered on the infusion bottle, making it convenient for doctors to check.

[0042] The working principle of this multifunctional infusion device is as follows:

[0043] When intravenous infusion is needed, the drive motor 310 causes the gear 320 to mesh with the rack 120, driving the sliding member 300 to slide on the U-shaped slide rail 100. The rotation of the motor 310 is controlled by the controller and adjusted to a suitable position. The telescopic rod 400 is then driven to adjust the height of the infusion box 200. After adjusting to a suitable height, the infusion bottle is first placed upside down in the container 210, with the bottle mouth aligned with the groove 240 and fastened. Then, the infusion tube needle is aligned with the bottom of the groove 240 and inserted into the bottle mouth. At this point, the infusion bottle is in contact with the groove 240 and the sensor 260. Finally, the needle of the infusion tube is connected to the patient, and intravenous infusion can begin.

[0044] During the infusion process, a temperature sensor monitors the temperature of the medication solution, and the temperature data is transmitted to the controller. The controller compares the set temperature with the measured temperature data to determine whether the medication solution needs to be heated. When heating is required, the spiral heating tube 250 is driven to heat the solution until the appropriate temperature is reached, and then the process is repeated to maintain the temperature and reduce patient discomfort. A level sensor monitors the flow rate. When the medication infusion is about to be completed, the level sensor will determine the flow rate based on the difference and promptly notify medical staff via an alarm to remove the needle or replace the empty infusion bottle with the next bottle of medication, reducing the workload of medical staff.

[0045] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
