Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to an internal medicine nursing IV drip stand. Background Technology

[0002] Internal medicine is a specialty of clinical medicine, serving as the foundation for almost all other clinical medical fields, and is often referred to as the "mother of medicine." Internal medicine encompasses the definition, etiology, pathogenesis, epidemiology, natural history, symptoms, signs, laboratory diagnosis, imaging examinations, differential diagnosis, diagnosis, treatment, and prognosis of diseases. Many internal medicine patients require intravenous infusions for treatment. To avoid backflow of blood and ensure proper flow of the medication, the IV bag is usually hung relatively high, creating a height difference between the bag and the patient's arm.

[0003] In existing IV stand technology, the hooks on the top are relatively high, which means that medical staff may not be able to reach them or may only be able to reach them when hanging IV bottles. This has significant limitations and does not allow for flexible adjustment of the hook height. Utility Model Content

Detailed Implementation

[0031] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0032] like Figures 1-5As shown in the figure, the utility model provides an intravenous drip stand for internal medicine nursing, which includes a counterweight base 1, a vertical pipe 2, at least one hanging ear rod 6 for hanging an infusion bottle, a lifting mechanism and a heating component 11; the vertical pipe 2 is vertically installed on the counterweight base 1;

[0033] The lifting mechanism includes a threaded rod 8, a lifting block 9, a sliding block 5 and a motor 7. Two fixing plates 201 are sequentially arranged inside the vertical pipe 2 along its height direction. The threaded rod 8 is rotatably installed between the two fixing plates 201. The output end of the motor 7 is connected to the top end of the threaded rod 8. The lifting block 9 is arranged inside the vertical pipe 2 and is threadedly connected to the threaded rod 8;

[0034] The sliding block 5 is sleeved outside the vertical pipe 2 and can slide along the vertical pipe 2. A strip-shaped hole is opened on the side surface of the vertical pipe 2. One end of the lifting block 9 passes through the strip-shaped hole and is connected to the inner wall of the sliding block 5;

[0035] The hanging ear rod 6 is installed on the sliding block 5;

[0036] The heating component 11 is installed on the vertical pipe 2 and is used to heat the infusion tube to raise the temperature of the liquid medicine in the infusion tube.

[0037] In this embodiment, medical staff or family members control the motor 7 to work according to the actual situation. The motor 7 drives the threaded rod 8 to rotate. Since the lifting block 9 is threadedly connected to the threaded rod 8 and the lifting block 9 is limited inside the vertical pipe 2, the lifting block 9 rises and falls inside the vertical pipe 2. Also, one end of the lifting block 9 passes through the strip-shaped hole and is connected to the inner wall of the sliding block 5, and the hanging ear rod 6 is installed on the sliding block 5, so that the sliding block 5 and the hanging ear rod 6 can be driven to do lifting motion, playing a role in adjusting the height of the hanging ear rod 6.

[0038] Compared with the traditional drip stand, this intravenous drip stand for internal medicine nursing has the following effects:

[0039] The height of the hanging ear rod 6 can be flexibly adjusted, so as to facilitate people of different heights to hang the infusion bottle. Moreover, with the motor 7 as the power source, there is no need to manually adjust the height of the hanging ear rod 6, which saves time and effort. In addition, in a cold environment, the heating component 11 can heat the infusion tube to raise the temperature of the liquid medicine in the infusion tube, ensuring the comfort of the patient.

[0040] As a preferred embodiment, as Figure 2 and Figure 3 shown, the lifting block 9 includes a first block body and a second block body which are connected. The first block body and the second block body are perpendicular to each other, and the first block body and the second block body form a "convex" shape. A threaded hole matching the threaded rod 8 is opened on the first block body, and the two end faces of the first block body are respectively in contact with the opposite inner wall surfaces of the vertical pipe 2. A strip-shaped hole in the shape of a long strip is opened on the side surface of the vertical pipe 2, and the length direction of the strip-shaped hole is the same as the height direction of the vertical pipe 2. The second block body passes through the strip-shaped hole and is connected to the inner wall of the sliding block 5.

[0041] Furthermore, the sliding block 5 is disc-shaped, and its top surface has a hole that passes through the sliding block 5. This hole is adapted to the riser 2. Multiple hanging rods 6 are provided, and multiple hanging rods 6 are evenly installed on the side of the sliding block 5 around the axis of the sliding block 5.

[0042] To improve the stability of the lifting block 9 during lifting, such as Figure 2 and Figure 3 As shown, at least one limiting rod 10 is fixedly installed between two fixed plates 201. The first block has a hole through which the limiting rod 10 passes, so that the limiting rod 10 and the first block can slide relative to each other.

[0043] In a preferred embodiment, a controller is installed on the riser 2. The controller is signal-connected to the motor 7, and controls the speed and direction of the motor 7 through the controller. The controller generates a PWM signal and controls the voltage and current of the motor 7 by adjusting the duty cycle of the signal (i.e., the proportion of high-level time to total time). The larger the duty cycle, the higher the voltage and current of the motor 7, thereby increasing the speed; conversely, the speed decreases.

[0044] When medical staff or family members adjust the height of the ear hook 6, they control the motor 7 through the controller. The motor 7 drives the threaded rod 8 to rotate, which in turn drives the lifting block 9, the sliding block 5, and the ear hook 6 to move up and down.

[0045] As a preferred embodiment, such as Figure 1 As shown, during intravenous infusion in a cold environment, the low-temperature medication carries away some heat after entering the body through the blood vessels, causing the patient to feel cold. To solve this problem, a heating assembly 11 is installed on the riser 2. The heating assembly 11 is installed on the side of the riser 2 and includes a mounting plate 12, a preheating box 13, a heating wire 16, and a temperature controller 14. The preheating box 13 is fixedly mounted on the mounting plate 12, which is mounted on the side of the riser 2 by bolts 15. Furthermore, as... Figure 4 As shown, a groove 131 is formed on the front side of the preheating box 13. The cross-section of the groove 131 is "Ω" shaped. The function of the groove 131 is to limit the infusion tube, so that the infusion tube contacts the inner wall of the groove 131. Figure 5 As shown, a heating chamber 132 is formed inside the preheating box 13, a temperature controller 14 is installed on the side of the preheating box 13, and a heating wire 16 is installed inside the heating chamber 132 and connected to the temperature controller 14.

[0046] Heating wire 16 raises the temperature inside heating chamber 132, thereby raising the temperature of inner wall of groove 131. Since the infusion tube and inner wall of groove 131 are in contact, the temperature of the medicine flowing through the infusion tube can be raised.

[0047] The thermostat 14 is an automatic control element that undergoes internal physical deformation based on changes in ambient temperature, thereby switching the circuit on or off to control the temperature. In practical applications, the thermostat 14, in conjunction with a solid-state relay, achieves precise temperature control of the heating wire 16. When the ambient temperature exceeds the set upper limit, the thermostat 14 controls the solid-state relay to disconnect the heating device's circuit; when the ambient temperature falls below the set lower limit, the thermostat 14 controls the solid-state relay to connect the heating device's circuit. This method achieves automatic temperature control, ensuring the temperature remains stable within the set range.

[0048] It should be noted that the thickness of the inner wall of the groove 131 is 1mm-2mm. This allows the inner wall of the groove 131 to preheat as the temperature of the heating chamber 132 gradually increases.

[0049] In order to monitor the temperature of the inner wall of the groove 131, such as Figure 5 As shown, a mounting hole is provided on the inner wall of the groove 131, and a temperature sensor 17 is installed in the mounting hole. The temperature sensor 17 is connected to the controller signal and monitors the temperature inside the groove 131 in real time. When the detected temperature reaches the upper limit, the temperature controller 14 controls the solid-state relay to disconnect the heating circuit to avoid overheating and improve safety.

[0050] When using this heating assembly 11, a section of the infusion tubing is inserted into the groove 131, and then the heating wire 16 is heated by the thermostat 14. This allows the medication flowing through the infusion tubing to be heated in cold environments, thereby appropriately increasing the temperature of the medication, improving the patient's comfort during infusion, and avoiding the problem of the patient feeling cold after the low-temperature medication enters the body through the blood vessels.

[0051] As an optional embodiment, such as Figure 1 As shown, a power supply interface 4 and a battery 3 that powers the power supply interface 4 are installed on the riser 2. The battery 3 also powers the motor 7 and the thermostat 14. The power supply interface 4 includes USB-A, USB-C, Lightning, and Micro USB interfaces. This allows the patient to charge their mobile phone using the power supply interface 4 during intravenous infusion.

[0052] Optionally, the bottom of the counterweight base 1 is equipped with multiple casters 101, which are universal casters with brakes. The casters 101 improve the flexibility of this IV stand and enhance its practicality.
