Description

Technical Field

[0001] This invention relates to the field of medical devices, and more particularly to an adjustable height infusion bottle holder. Background Technology

[0002] Traditional infusion bottle holders are fixed, making them inconvenient for medical staff to move and unsuitable for timely allocation of hospital resources. Furthermore, the height of the infusion bottle holder is fixed, and different medications require different infusion rates. Generally, the flow rate can only be controlled by a regulating valve on the infusion tubing, thus controlling the infusion rate. However, due to the limited infusion rate, the infusion time is usually long. Patients experience significant discomfort from prolonged sitting or lying down during the infusion process, requiring them to adjust from a sitting or lying position to a standing position. During this adjustment, the relative position of the infusion site and the IV bag shortens, the infusion pressure decreases, and the infusion rate slows down. This reduces the concentration of the medication in the patient's body per unit time, affecting the full efficacy of the medication. If further adjustments are made at this time... The flow rate adjustment valve needs to be readjusted every time the patient sits down again, which is not only time-consuming and laborious, but also has low adjustment accuracy. Existing technology (CN205667662U) is an infusion bottle holder that can rotate a handle, which moves the connecting sleeve along the length of the support rod through a transmission component to adjust the position of the hook, that is, to adjust the infusion bottle to a suitable position. This solves the problem that the infusion bottle is too high and it is difficult to adjust the position of the infusion bottle when the patient needs to adjust his position or sitting posture, making it inconvenient to use. However, when adjusting the position of the infusion bottle, the center of gravity of the holder is also raised. If the holder needs to be moved at this time, it is very easy for the holder to tip over, which may lead to damage to the infusion bottle or leakage of medicine. Summary of the Invention

[0003] To overcome the shortcomings of existing infusion bottle holders, such as increased center of gravity when adjusting height, easy tipping during movement, and inability to automatically maintain a stable infusion rate according to changes in patient position, thus affecting safety and efficacy, this invention provides an adjustable height infusion bottle holder.

[0004] The technical implementation of this invention is as follows: an adjustable height infusion bottle holder, comprising a base and several supports fixed on the base; each support is fixedly connected to a movable wheel; a storage battery is installed inside the base; an electric push rod is mounted on the base; a cross-shaped bracket is fixedly connected to the telescopic part of the electric push rod; several hooks are provided on the cross-shaped bracket; a sleeve is fixedly connected to the fixing part of the electric push rod; the lower part of the sleeve is fixedly connected to the base; several sliders are slidably connected to the sleeve; an elastic plate is fixedly connected to each slider; each elastic plate is fixedly connected to a support; a first spring is fixedly connected to each slider; all the first springs are fixedly connected to the sleeve.

[0005] Optionally, the chassis is provided with a counterweight.

[0006] Optionally, the movable wheel is covered with a silicone layer.

[0007] Optionally, the hook end of the cross-shaped bracket is provided with a rubber sleeve.

[0008] Optionally, the electric push rod fixing part is fixedly connected to a heating sleeve; the heating sleeve is located above the sleeve; a plurality of heating wires arranged in a ring array are installed inside the heating sleeve; a plurality of first limiting strips are fixedly connected to the outside of the heating sleeve; each of the first limiting strips has a through groove, and the through groove on the side away from the heating sleeve has an opening.

[0009] Optionally, a pressure sensor is provided inside the heating jacket.

[0010] Optionally, the first limiting strip is made of a thermally conductive material.

[0011] Optionally, the heating jacket is detachably connected to a plurality of protective plates; each protective plate is located between two adjacent first limiting strips.

[0012] Optionally, the protective sheet is made of sponge material.

[0013] Optionally, the electric push rod fixing part is slidably connected to a collar; the collar is located above the heating sleeve; a plurality of second springs are fixedly connected to the lower part of the collar; all the second springs are fixedly connected to the heating sleeve; a plurality of second limiting strips are fixedly connected to the side of the collar; each second limiting strip has a through groove, and the through groove on the side away from the heating sleeve has an opening; the electric push rod fixing part is slidably connected to a limiting ring; the limiting ring is located above the collar; the collar is in contact with the limiting ring.

[0014] The present invention has the following advantages: 1. By controlling the extension and retraction of the electric push rod, the infusion pressure of different medicines is automatically controlled, thereby adapting to the infusion speed required by different medicines, so that the efficacy of the medicine can be fully exerted. In addition, a sleeve is set to reinforce and protect the electric push rod, so as to avoid the center of gravity of the cross bracket shift when the number of infusion bottles suspended by the cross bracket is odd. Furthermore, an elastic plate and a first spring are set to ensure the stability of the bracket when the electric push rod is subjected to force on the side, effectively preventing the bracket from easily tipping over when it is pushed to move.

[0015] 2. By setting up a heating sleeve, the infusion tube fixed on the first limiting strip can be heated, thereby heating the flowing medicine, solving the problem that when the temperature of the medicine is low in winter, directly injecting the medicine into the patient's body will cause obvious discomfort.

[0016] 3. By setting a protective sheet made of sponge material on the outside of the heating sleeve, the friction when the patient or medical staff holds the heating sleeve can be increased. The soft touch of the sponge material allows the protective sheet to deform, making it easier for people with different hand sizes to hold the hanger and making it easier to use. The protective sheet will also be heated by the heating sleeve, making it easier for patients or medical staff to hold the hanger and move it in cold winter.

[0017] The present invention also has the following effects: By setting up a movable collar and a second limiting strip, and leaving a portion of the infusion tubing between the second and first limiting strips, when the patient adjusts from a sitting or lying position to a standing position, it not only avoids changes in the relative distance between the infusion site and the infusion bottle body, thus affecting the infusion pressure and altering the infusion effect, but also prevents the infusion tubing from pulling on the infusion needle, causing secondary injury to the patient. Furthermore, the infusion tubing between the second limiting strip and the infusion bottle body is kept taut, effectively reducing the shaking of the infusion bottle body and its impact on the infusion process.

Detailed Implementation

[0020] References to embodiments herein mean that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0021] Example 1: An adjustable height infusion bottle holder, according to... Figures 1-6 As shown, it includes a chassis 1, a bracket 2, and casters 3; five brackets 2 arranged in a circular array are fixed to the side of the chassis 1; each bracket 2 is fixed to a caster 3; each caster 3 is equipped with a brake pedal; It also includes an electric push rod 4, a cross bracket 5, a sleeve 6, a slider 7, an elastic plate 8, and a first spring 9; a battery is installed inside the chassis 1; the electric push rod 4 is mounted on the chassis 1; the telescopic part of the electric push rod 4 is fixedly connected to the cross bracket 5; the cross bracket 5 is provided with four hooks 501 arranged in a ring array; the fixed part of the electric push rod 4 is fixedly connected to the sleeve 6; the lower part of the sleeve 6 is fixedly connected to the chassis 1; five sliders 7 arranged in a ring array are slidably connected to the sleeve 6; each slider 7 is fixedly connected to an elastic plate 8; each elastic plate 8 is fixedly connected to a bracket 2; each slider 7 is fixedly connected to a first spring 9; all the first springs 9 are fixedly connected to the sleeve 6.

[0022] The working steps of the above embodiments are as follows: First, place the hanger on the ground and depress the brake pedals on each of the casters 3 to prevent them from moving. Five ring-shaped support brackets 2 stably support the electric push rod 4, which is powered by a battery inside the chassis 1. Controlling the retraction of the electric push rod 4 lowers the cross-shaped hanger 5, allowing medical personnel to invert the infusion bottle body 111 and hang it on the hook 501. Figure 6 As shown, one end of the infusion tube 222 is then inserted into the lower part of the infusion bottle body 111, and the other end of the infusion tube 222 is connected to the infusion needle. The infusion needle is then inserted into the blood vessel in the patient's hand. The infusion tube 222 near the patient's hand is fixed with tape to prevent the infusion needle from shifting when the patient's hand moves, thus avoiding secondary injury to the patient. Then, depending on the different medications, the extension of the electric push rod 4 is controlled to adjust the injection pressure of different medications, so that the medication can be injected into the patient's body at an appropriate injection speed, and the efficacy of the medication can be fully exerted.

[0023] Considering the strict requirements on infusion rate when administering intravenous fluids to patients via the infusion bottle body 111, and the fact that some medications require a slower infusion rate, resulting in a longer infusion time, if an odd number of infusion bottles 111 are suspended from the cross bracket 5, the center of gravity of the cross bracket 5 will shift. Furthermore, as the infusion process continues, the center of gravity of the electric push rod 4 will also shift, causing local shear forces at the connection between the electric push rod 4 and the base 1, which may lead to failure of the connection and a reduction in the lifespan of the bracket. Therefore, a sleeve 6 is installed at the connection between the electric push rod 4 and the base 1 to protect the connection and reduce the shaking of the cross bracket 5 during infusion, preventing the infusion bottles on the cross bracket 5 from shaking and causing the infusion rate to be too fast or too slow, thus affecting the patient's absorption of the medication.

[0024] Considering that intravenous infusion takes a long time, patients may experience discomfort from sitting or lying down for extended periods. Furthermore, if they need to use the restroom during this time, the hanging frame needs to be moved. This is done by sequentially pulling up the brake pedals on each of the moving wheels 3. At this point, the patient or medical staff can push the hanging frame to move. Because the infusion bottle 111 is suspended at a high position, the center of gravity of the hanging frame is raised. Therefore, if the patient or medical staff pushes the frame from a position not aligned with the center of gravity, it is prone to tipping over during movement, potentially causing the infusion bottle 111 to break or leak. Therefore, the base 1 and the five supports 2 are designed with a five-star base configuration. When a patient or medical staff pushes the hanging frame, an additional pushing force is applied to the fixed part of the electric push rod 4. The angle between two adjacent brackets 2 is an acute angle, which can fully distribute the force on the fixed part of the electric push rod 4, ensuring the stability of the hanging frame and preventing it from tipping over. When the electric push rod 4 is pushed, it tilts in the direction of the force, and the elastic plate 8 pushes the slider 7 to move up the sleeve 6, compressing the corresponding first spring 9. Meanwhile, the slider 7 on the other side moves down, stretching the corresponding first spring 9, keeping the electric push rod 4 neutral. This ensures the stability of the hanging frame and effectively prevents it from tipping over when pushed.

[0025] The chassis 1 is equipped with a counterweight to lower the center of gravity of the entire hanger.

[0026] The movable wheel 3 is covered with a silicone layer to absorb shock when the bracket is moved and to increase the grip of the movable wheel 3, ensuring the smooth movement of the bracket.

[0027] The hook 501 of the cross bracket 5 is provided with a rubber sleeve at the end to prevent the end of the hook 501 from scratching the body of the infusion bottle 111.

[0028] It also includes a heating sleeve 10 and a first limiting strip 11; the heating sleeve 10 is fixedly connected to the electric push rod 4 fixing part; the heating sleeve 10 is located above the sleeve 6; a number of heating wires 1001 arranged in a ring array are installed inside the heating sleeve 10; four first limiting strips 11 arranged in a ring array are fixedly connected to the outside of the heating sleeve 10; each first limiting strip 11 has a through groove, and the through groove on the side away from the heating sleeve 10 has an opening.

[0029] A pressure sensor is installed inside the heating jacket 10.

[0030] The first limiting strip 11 is made of thermally conductive material.

[0031] It also includes protective plates 12; four protective plates 12 are detachably connected to the heating jacket 10 in a ring array; each protective plate 12 is located between two adjacent first limiting bars 11.

[0032] Protective sheet 12 is made of sponge material.

[0033] In addition to the above-mentioned technical effects, the present invention also has the following advantages: First, by setting a heating sleeve 10 at the fixed part of the electric push rod 4, after the medical staff inserts one end of the infusion tube 222 into the body of the infusion bottle 111, the middle part of the infusion tube 222 is pressed into the through groove of the first limiting strip 11. Thus, the infusion tube 222 is restricted by the first limiting strip 11, while one end of the infusion tube 222 is still connected to the body of the infusion bottle 111. This reduces the problem of the infusion bottle body 111 shaking and affecting the infusion effect.

[0034] Secondly, by activating the heating wire 1001, heat is transferred through the first limiting bar 11 to heat the infusion tube 222 in the channel. This heats the medicine flowing through the infusion tube 222, solving the problem that the medicine is too cold in winter and direct administration of the medicine into the patient's body would cause significant discomfort.

[0035] Third, by setting a protective sheet 12 made of sponge material on the outside of the heating sleeve 10, the friction force when the patient or medical staff holds the heating sleeve 10 can be increased. The soft touch of the sponge material allows the protective sheet 12 to deform, which makes it easier for people with different hand sizes to hold the hanger and facilitates its use.

[0036] Fourth, in conjunction with the heating function of the heating sleeve 10, the protective plate 12 will also be heated by the heating sleeve 10. Therefore, when the patient or medical staff holds the protective plate 12, the protective plate 12 can make the patient or medical staff feel warm. This makes it easier for the patient or medical staff to hold the hanger and move it in the cold winter, avoiding the situation in the existing technology where the hanger does not have a heating function, and the patient or medical staff often have to endure the cold hanger when holding and moving it, which brings great physiological discomfort.

[0037] Example 2: Based on Example 1, according to Figures 1-6 As shown, it also includes a collar 13, a second spring 14, a second limiting strip 15, and a limiting ring 16; the fixing part of the electric push rod 4 is slidably connected to the collar 13; the collar 13 is located above the heating sleeve 10; four second springs 14 arranged in a ring array are fixedly connected to the lower part of the collar 13; all the second springs 14 are fixedly connected to the heating sleeve 10; four second limiting strips 15 arranged in a ring array are fixedly connected to the side of the collar 13; each second limiting strip 15 has a through groove, and the through groove on the side away from the heating sleeve 10 has an opening; the fixing part of the electric push rod 4 is slidably connected to the limiting ring 16; the limiting ring 16 is located above the collar 13; the collar 13 is in contact with the limiting ring 16.

[0038] The working steps of the above embodiments are as follows: Considering the prolonged infusion process, patients are generally in a sitting or lying position. When they need to relieve themselves or stand up to stretch, they need to change from a sitting or lying position to a standing position, and they will also habitually bend their arm while receiving the infusion. This shortens the relative distance between the infusion site and the infusion bottle body 111, resulting in a decrease in the injection pressure of the medication and a slower injection speed. Consequently, the concentration of medication injected into the patient's body per unit time is insufficient to achieve the theoretical therapeutic effect of the medication. Therefore, a movable collar 13 is added. After inserting one end of the infusion tube 222 into the infusion bottle body 111, the infusion tube 222 is pressed into the groove of the second limiting strip 15, and then pressed into the groove of the first limiting strip 11. A 10-20 cm long section of the infusion tube 222 is left between the first limiting strip 11 and the second limiting strip 15. Figure 6As shown, when the patient stands up, the distance between the infusion position and the infusion bottle body 111 is closer. At this time, the electric push rod 4 extends, simultaneously moving the infusion bottle body 111 upward. Simultaneously, the infusion bottle body 111 also moves the connected infusion tube 222 upward. The infusion tube 222, the second limiting strip 15, and the collar 13 also move upward, stretching all the second springs 14. At this time, the 10-20 cm long infusion tube 222 unfolds, preventing the infusion tube 222 from being dragged within the first limiting strip 11, thus preventing the infusion tube 222 from being pulled out. 22. Pulling the IV needle could cause secondary injury to the patient. The patient or medical staff can then move the frame. When the patient is comfortable or wants to sit down to rest, the electric push rod 4 can be retracted again. All the second springs 14 retract, causing the collar 13 and the second limiting strip 15 to reset. The IV tubing 222 between the second limiting strip 15 and the first limiting strip 11 is then retracted. This allows the patient to adjust from a sitting to a standing position without easily pulling the IV needle, avoiding the discomfort caused by prolonged sitting or lying down for IV infusion.

[0039] In addition to the above-mentioned technical effects, the present invention also has the following advantages: During the extension and retraction of the infusion tube 222, the infusion bottle body 111 shakes. The infusion bottle body 111 is connected to the second limiting strip 15 through the infusion tube 222. The infusion tube 222 between the second limiting strip 15 and the infusion bottle body 111 is in a taut state. Finally, the shaking energy of the infusion bottle body 111 is limited by the pulling of the infusion tube 222 and then absorbed by the elastic damping of the second spring 14, effectively reducing the shaking of the infusion bottle body 111 and its impact on the infusion process.
