Description

Technical Field

[0001] The present invention relates to the field of ambulance first aid technology, in particular to an auxiliary device for infusion. Background Art

[0002] In the modern medical emergency system, ambulances play a vital role in the process of transporting and treating patients. In order to maintain the vital signs of critically ill patients, patients are usually required to receive infusions. However, when an ambulance is driving, the external road conditions are complex and changeable, and bumps, sudden acceleration and sudden braking often occur.

[0003] When performing infusion therapy on patients, the stability of the infusion bottle becomes a key issue. Traditional infusion methods face many challenges in such an unstable environment. When an ambulance encounters an emergency and needs to brake suddenly, if the infusion bottle is not effectively fixed, it will shake violently under the action of inertia, which can easily cause the infusion tube to fall off the patient and interrupt the infusion therapy, which may be fatal for patients who urgently need drugs to maintain vital signs. On the other hand, even if the outside of the infusion bottle is fixed, at the moment of emergency braking, due to inertia, the infusion bottle will still move forward, exerting a large pressure on the liquid in the bottle, causing the infusion speed to rise rapidly in a short time. This may not only exceed the safe infusion speed range, increase the patient's heart burden or cause other adverse reactions, but also affect the accurate infusion dose and time of the drug, thereby adversely affecting the maintenance of the vital signs of the emergency patient. Therefore, in order to ensure the safety and effectiveness of patient infusion during the ambulance emergency treatment process, solving the stability of the infusion bottle under complex road conditions and the infusion speed control problem has become an important topic in the current research and development and improvement of ambulance emergency equipment.

[0004] In view of this, we propose an auxiliary device for infusion to improve the deficiencies in the prior art. Summary of the invention

[0005] The object of the present invention is to provide an auxiliary device for infusion to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above object, the present invention provides an auxiliary device for infusion, comprising a fixing seat fixedly connected to the top wall of an ambulance, wherein a suspension assembly is fixedly connected to the top of the fixing seat;

[0007] Among them, the suspension assembly includes a U-shaped suspension bin. The opening of the U-shaped suspension bin is consistent with the moving direction of the auxiliary equipment for infusion. One side of the opening of the U-shaped suspension bin is fixedly connected with a plurality of extension rods. One end of the plurality of extension rods away from the U-shaped suspension bin is fixedly connected with a limiting plate. A buffer assembly is slidably connected to the plurality of extension rods. A lifting assembly is arranged in the suspension assembly. The lifting assembly at least includes a sliding seat slidably connected to the inner bottom wall of the U-shaped suspension bin.

[0008] The installation assembly is used to store the infusion bottle. During the stable driving of the ambulance, one end of the buffer assembly is in contact with the sliding seat. The buffer assembly is used to fix the installation assembly at a higher position. When the ambulance brakes emergently, the buffer assembly can buffer the infusion bottle stored in the installation assembly. The installation assembly without the limit of the buffer assembly drops to a lower position. The installation assembly after the position is lowered is used to reduce the extrusion pressure inside the infusion bottle. After the ambulance completes the emergency braking, the buffer assembly drives the installation assembly to reset.

[0009] As a further improvement of the technical solution, the buffer assembly includes a connecting bolt slidably connected to a plurality of extension rods. A buffer plate is fixedly connected to one side of the plurality of connecting bolts close to each other. A top rod is fixedly connected to the side of the buffer plate close to the U-shaped suspension bin. The buffer assembly further includes a plurality of springs outside the plurality of extension rods. Each spring is located between each connecting bolt and the limiting plate.

[0010] As a further improvement of the technical solution, the lifting assembly further includes a guide rod fixedly connected to the inner wall of the side of the U-shaped suspension bin away from the opening. The guide rod is slidably connected to the sliding seat. A suspension rope is fixedly connected to the bottom of the sliding seat on the side close to the opening of the U-shaped suspension bin.

[0011] As a further improvement of the technical solution, the installation assembly includes a hanging box. An installation seat is arranged in the hanging box. A plurality of placement grooves are opened at the top of the installation seat. Infusion ports are opened at the bottoms of the plurality of placement grooves. A pick-up frame is fixedly connected to the top edge of the hanging box. The pick-up frame is fixedly connected to the suspension rope.

[0012] As a further improvement of the technical solution, the material of the suspension rope is polyurethane elastic fiber.

[0013] As a further improvement of the technical solution, a plurality of sliding rods are fixedly connected to the edge of the hanging box. One end of the plurality of sliding rods away from the hanging box is slidably connected to the buffer plate.

[0014] As a further improvement of the technical solution, the material of the installation seat is rubber.

[0033] Embodiment

[0034] Please refer to Figures 1-6 As shown, the purpose of this embodiment is to provide an auxiliary device for infusion, including a fixed seat 10 fixedly connected to the inner top wall of the ambulance, and a suspension assembly 20 fixedly connected to the top of the fixed seat 10;

[0035] Among them, the suspension assembly 20 includes a U-shaped suspension bin 21, the opening of the U-shaped suspension bin 21 is consistent with the moving direction of the auxiliary device for infusion, one side of the opening of the U-shaped suspension bin 21 is fixedly connected with a plurality of extension rods 22, one end of the plurality of extension rods 22 away from the U-shaped suspension bin 21 is fixedly connected with a limiting plate 23, a buffer assembly 30 is slidably connected to the plurality of extension rods 22, a lifting assembly 40 is arranged in the suspension assembly 20, and the lifting assembly 40 at least includes a sliding seat 42 slidably connected to the inner bottom wall of the U-shaped suspension bin 21. The bottom of the buffer assembly 30 and the lifting assembly 40 is fixedly connected with a mounting assembly 50;

[0036] The installation component 50 is used to store the infusion bottle. During the stable driving of the ambulance, one end of the buffer component 30 is in contact with the sliding seat 42. The buffer component 30 is used to fix the installation component 50 at a higher position. When the ambulance brakes suddenly, the buffer component 30 can buffer the infusion bottle stored in the installation component 50. The installation component 50 without the limit of the buffer component 30 drops to a lower position. The installation component 50 after the position is lowered is used to reduce the extrusion pressure inside the infusion bottle. After the ambulance completes the emergency braking, the buffer component 30 drives the installation component 50 to reset automatically.

[0037] During the driving of the ambulance, it will frequently accelerate, decelerate, turn and jolt. If the position of the hanging box 51 is not fixed, the infusion bottle is likely to shake violently or even fall off, resulting in the interruption of infusion, which may have serious consequences for patients in urgent need of drug treatment and even endanger their lives. Therefore, the buffer component 30 is provided to protect the infusion bottle when the ambulance brakes.

[0038] As Figure 3 shown, first, the specific structure of the buffer component 30 is disclosed: The buffer component 30 includes connecting bolts 32 slidably connected to a plurality of extension rods 22. A buffer plate 31 is fixedly connected to one side of the plurality of connecting bolts 32 close to each other. A push rod 33 is fixedly connected to the buffer plate 31 on the side close to the U-shaped suspension bin 21. The buffer component 30 further includes a plurality of springs 34 outside the plurality of extension rods 22. Each spring 34 is located between each connecting bolt 32 and the limiting plate 23.

[0039] Further, when the ambulance brakes suddenly, the installation component 50 will drive the sliding rod 11 to move forward under the action of inertia. The sliding rod 11 then drives the buffer plate 31 to slide along the extension rod 22. During this process, the spring 34 is compressed, and at the same time, the push rod 33 moves forward together with the buffer plate 31. At this time, the push rod 33 removes the limit on the sliding seat 42, and the installation component 50 will drive the suspension rope 43 to move downward under its own gravity. After the vehicle becomes stable, without the original inertia of the installation component 50, the buffer plate 31 resets under the action of the restoring force of the spring 34. The buffer plate 31 then drives the push rod 33 to push the sliding seat 42 back to the original position, and the sliding seat 42 pulls the installation component 50 to the original height through the suspension rope 43.

[0040] Even if the outside of the infusion bottle is fixed, at the moment of emergency braking, due to inertia, the infusion bottle will still move forward, exerting a large pressure on the liquid in the bottle, causing the infusion speed to increase rapidly in a short period of time. This may not only exceed the safe infusion speed range, increase the patient's heart burden or cause other adverse reactions, but also affect the accurate infusion dose and time of the drug. Therefore, a lifting component 40 is provided, whose function is to lower the height of the infusion bottle in the mounting component 50 at the moment of emergency braking of the ambulance, thereby reducing the pressure exerted on the liquid in the bottle at the moment of squeezing of the infusion bottle.

[0041] Figure 4 The figure shows the working state when the lifting assembly 40 and the connecting bolt 32 cooperate with each other. The specific structure of the lifting assembly 40 is disclosed below. The lifting assembly 40 also includes a guide rod 41 fixedly connected to the inner wall of the U-shaped hanging bin 21 away from the opening. The guide rod 41 is slidably connected to a slide seat 42. The bottom of the slide seat 42 is fixedly connected to a suspension rope 43 on the side close to the opening of the U-shaped hanging bin 21.

[0042] Furthermore, the material of the hanging rope 43 is polyurethane elastic fiber; after the top rod 33 removes the limit on the slide seat 42, the installation component 50 will drive the hanging rope 43 to move downward under the action of its own gravity. The inertia of the infusion bottle after the height is lowered becomes smaller, and the forward impact force generated during emergency braking is relatively weak. The infusion bottle and the infusion tube are relatively more stable and not easy to fall off or shift; at the same time, the fluctuation of the liquid pressure in the bottle is relatively small, and the infusion speed is also relatively small. The impact can reduce the risk to the patient caused by the sudden change of the infusion speed to a certain extent.

[0043] In the case of bumps and shakes during the driving of the ambulance, prevent the infusion bottles from colliding with each other and being damaged or falling over, and ensure that each infusion bottle can maintain a relatively stable position. If an infusion bottle breaks or other unexpected situations occur, if it is not prevented, the drug solution will leak to other infusion bottles, causing cross contamination and drug mixing;

[0044] like Figure 5 As shown, the mounting assembly 50 includes a hanging box 51, a mounting seat 52 is provided inside the hanging box 51, a plurality of placement grooves 53 are provided on the top of the mounting seat 52, an infusion port 54 is provided on the bottom of the plurality of placement grooves 53, and a cantilever frame 55 is fixedly connected to the top of the edge of the hanging box 51, and the cantilever frame 55 is fixedly connected to the suspension rope 43.

[0045] The improvement lies in that the mounting seat 52 is made of rubber. On the one hand, the mounting seat 52 made of rubber can absorb and disperse impact forces from different directions, reduce the impact of external vibrations on the infusion bottle, and further ensure the safety of infusion. On the other hand, rubber, due to its strong elasticity and durability, can withstand the impact caused by multiple sudden brakes and the like, and maintain a good buffering effect for a long time.

[0046] In order to enable the hanging box 51 to travel a longer distance during the braking process of the ambulance, thereby enhancing the buffering effect, a pair of sliding rods 11 for guiding the up-and-down movement of the hanging box 51 are provided.

[0047] Figure 5 It shows the working state when the hanging box 51 is pulled up and down by the suspension rope 43 under the guidance of the sliding rods 11. A number of sliding rods 11 are fixedly connected to the edge of the hanging box 51, and one end of each of the number of sliding rods 11 away from the hanging box 51 is slidably connected to the buffer plate 31.

[0048] The improvement lies in that when the ambulance brakes, on the one hand, the hanging box 51 will be driven by the sliding rods 11 and move horizontally along with the buffer plate 31; on the other hand, after the sliding seat 42 loses the limit of the ejector rod 33, the hanging box 51 will move downward by pulling the suspension rope 43 under the action of the gravity of the infusion bottle. In the case of the same braking distance, the infusion bottle that moves in both the horizontal and vertical directions passes a longer distance, thus having a better buffering effect on the infusion bottle.

[0049] In summary, the working principle of this solution is as follows: First, place the infusion bottle in the mounting seat 52. During the smooth driving of the ambulance, one end of the ejector rod 33 is in contact with the sliding seat 42, thereby fixing the infusion bottle at a higher position. When the ambulance brakes suddenly, the hanging box 51 will, under the action of inertia, drive the sliding rods 11 to move forward, and the sliding rods 11 will drive the buffer plate 31 to slide along the extension rod 22. During this process, the spring 34 is compressed, and at the same time, the ejector rod 33 moves forward together with the buffer plate 31. At this time, the ejector rod 33 removes the limit on the sliding seat 42, and the hanging box 51 will drive the suspension rope 43 to move downward under its own gravity. After the vehicle becomes stable, losing the original inertial effect of the hanging box 51, the buffer plate 31 will reset under the restoring force of the spring 34, and the buffer plate 31 will drive the ejector rod 33 to push the sliding seat 42 back to its original position, and the sliding seat 42 will pull the infusion bottle in the hanging box 51 to the original height through the suspension rope 43.

Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present invention and are not used to limit the present invention.
