Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, and in particular to an infusion fixation device for pre-hospital emergency treatment. Background Art

[0002] In pre-hospital emergency scenarios such as ambulance transfer and field rescue, infusion therapy is crucial to maintaining the patient's vital signs; however, traditional infusion fixation devices are difficult to meet safety requirements in complex environments due to design limitations.

[0003] Currently, most commonly used infusion fixation devices use a single clamping method, mainly composed of hard plastic or metal clips, and rely on the friction between the clip and the infusion bottle to achieve fixation. During ambulance transportation, the vehicle frequently encounters speed bumps, potholes, and emergency braking. The continuous high-intensity bumps and vibrations will continuously weaken the friction, causing the clip to loosen and fall off, which in turn causes the infusion bottle to swing and become unstable. This may cause the infusion treatment to be interrupted, seriously affecting the patient's treatment.

[0004] In field rescue scenarios, the complexity of the environment further exacerbates the problem. The rugged mountain roads of mountain rescue and the dense vegetation of jungle rescue make it extremely easy for infusion tubes, which lack effective collection and fixation designs, to become entangled in branches and vines, or be pulled unconsciously by personnel. This unintended pulling can cause leakage and air to enter the system, or even damage blood vessels at the puncture site, leading to serious complications.

[0005] In addition, when emergency treatment is carried out in cold environments, such as in the wild in winter or in polar regions, traditional infusion devices do not have a liquid heating function. Injecting cold liquid into the patient's body at low temperatures will stimulate vasoconstriction, causing chills, vasospasm, and even affect heart function, increasing the risk of treatment. At the same time, low temperatures will also increase the viscosity of the liquid and slow the flow rate, affecting the treatment effect.

[0006] In summary, the existing infusion fixation devices for pre-hospital emergency care have technical defects such as a single fixation method, lack of effective storage for infusion tubes, and inability to cope with low temperatures. They are difficult to meet the clinical needs of pre-hospital emergency care, and there is an urgent need to develop new devices to solve the above problems. Summary of the Invention

[0033] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0034] The embodiment of the present invention discloses an infusion fixation device for pre-hospital emergency treatment.

[0035] Reference Figure 1-7 , a pre-hospital emergency infusion fixing device, comprising a fixing frame 1, a control panel 3 fixed on the surface of the fixing frame 1, a storage frame 2 fixed inside the fixing frame 1, and a locking assembly provided inside the fixing frame 1;

[0036] The inner wall of the storage frame 2 is fixedly connected to the placement frame 4 through a connecting block 13, and the inner wall of the placement frame 4 is fixedly connected to the elastic ring 6 through a number of elastic connecting belts 5. An elastic wrapping belt 7 is fixedly installed on the surface of the elastic ring 6, and an outer wrapping belt 8 is fixed on the surface of the elastic wrapping belt 7, and a limited fixing rope 9 is slidingly set inside the outer wrapping belt 8. One end of the limited fixing rope 9 is fixedly connected to the surface of the fixed frame 1, and the other end slides through the fixed frame 1 and is connected to the locking assembly; the injection bottle body is placed in the placement frame 4 so that the bottle mouth falls into the elastic ring 6, and then the locking assembly is started by operating the control panel 3. The locking assembly pulls the limited fixing rope 9 to tighten, driving the elastic wrapping belt 7 and the elastic ring 6 to shrink synchronously, wrapping and fixing the injection bottle body from multiple dimensions, and the elastic connecting belt 5 can provide a buffering and shock-absorbing effect in a bumpy environment, and cooperates with the tightening effect of the locking assembly to ensure that the bottle body remains stable in complex first aid scenarios, effectively avoiding the risk of shaking, displacement or falling off.

[0037] The locking assembly includes a motor A10. The output shaft of the motor A10 rotates through the fixed frame 1 and is fixedly connected to the transmission gear 11. The transmission gear 11 is rotatably mounted in the groove 101 of the fixed frame 1. The inner walls of the groove 101 at both ends are rotatably mounted with rotating shaft wheels 12. One end of the surface of the rotating shaft wheel 12 is fixedly connected to the limit fixing rope 9. The rotating shaft wheel 12 is meshed with the transmission gear 11.

[0038] An instruction is sent to the motor A10 through the control panel 3, and the output shaft of the motor A10 starts to rotate, driving the transmission gear 11 to rotate in the groove 101. Due to the meshing transmission relationship between the transmission gear 11 and the rotating shaft wheel 12, the rotating shaft wheel 12 rotates synchronously, gradually tightening the limiting fixing rope 9 wrapped around its surface, achieving stable pulling of the limiting fixing rope 9, and then driving the outer wrapping belt 8 and the elastic ring 6 to contract, completing the tightening operation of the injection bottle body.

[0039] Both ends of the placement frame 4 are respectively provided with sieve plates 14 , and a heater 15 is fixedly mounted on the surface of the sieve plate 14 , the output end of the heater 15 is connected to a heat pipe 16 , and a temperature sensor is provided in the placement frame 4 .

[0040] The heater 15, the temperature sensor and the control panel 3 are electrically connected. The temperature data collected by the temperature sensing device can be fed back to the control panel 3, thereby realizing temperature control of the heater 15 and ensuring that the stability of the liquid in the infusion bottle can be improved within a certain temperature range.

[0041] The fixed frame 1 is fixedly connected to the support frame 20 through the support rod 22. The support frame 20 is fixedly installed on the upper surface of the clamping slot frame 17. Threaded holes are respectively provided at both ends of the bottom of the clamping slot frame 17, and the threaded holes are threadedly connected to the threaded rod 19. The top of the threaded rod 19 is rotatably installed with a rubber pad 18. The clamping slot frame 17 can be flexibly mounted on various tubular or plate-like structures such as the patient's bedside guardrail, the side of the ambulance stretcher, etc.

[0042] A pipeline collecting assembly 21 is fixedly provided on one side of the support frame 20 , and a transparent frame 35 is fixedly provided on the outer side of the pipeline collecting assembly 21 .

[0043] The pipeline collection assembly 21 includes a guide frame 23 and a motor B24. The guide frame 23 and the motor B24 are fixedly mounted on the surface of the support frame 20. The output shaft of the motor B24 is fixedly connected to the bidirectional screw 25. The surface of the bidirectional screw 25 is threaded with a threaded sleeve 26. The surface of the threaded sleeve 26 is fixedly connected to the slide rod 28 through an L-shaped connecting plate 27. The outer sliding sleeve of the slide rod 28 is provided with a sliding sleeve 30. The surface of the sliding sleeve 30 is fixedly mounted with a slider 34. The top of the slider 34 is slidably spliced with the bottom slide groove of the guide frame 23.

[0044] A spring frame 29 is provided on the outer side of the slide rod 28. One end of the spring frame 29 is fixedly connected to the L-shaped connecting plate 27, and the other end is fixedly connected to the slide sleeve 30.

[0045] The bottom end of the sliding sleeve 30 is fixedly connected to the fixing sleeve 32 through an L-shaped connecting rod 31. The fixing sleeve 32 is made of silicone and is used for fixing the infusion catheter.

[0046] In the present invention, when in use, according to the actual first aid scenario, a suitable installation location is selected, such as the side of an ambulance stretcher, a patient bedside guardrail, etc.; the clip slot frame 17 is aligned with the target installation position, and the threaded rod 19 is rotated to make the rubber pad 18 fit tightly against the installation surface. The clip slot frame 17 is firmly fixed to the installation position through the threaded connection between the threaded rod 19 and the threaded hole, thereby completing the preliminary installation of the device.

[0047] First, pull open the elastic ring 6 and place the injection bottle body in the placement frame 4, ensuring that the bottle mouth falls into the elastic ring 6 accurately. After the preliminary fixation by the elastic ring 6 is completed, the operator starts the locking assembly through the control panel 3. The control panel 3 sends a command to the motor A10, and the output shaft of the motor A10 starts to rotate, driving the transmission gear 11 to rotate in the groove 101. Due to the meshing transmission relationship between the transmission gear 11 and the rotating shaft wheel 12, the rotating shaft wheel 12 rotates synchronously therewith, gradually tightening the limiting fixing rope 9 wrapped around its surface. During the tightening of the limiting fixing rope 9, the outer wrapping belt 8, the elastic wrapping belt 7 and the elastic ring 6 are pulled to shrink synchronously, so that the injection bottle body is wrapped and fixed. It is worth mentioning that in order to improve the fixation, it is not necessary to put the outer wrapping belt 8 on the bottle mouth, the middle section of the infusion bottle is also fine; the elastic connecting belt 5 provides a buffer during the fixation process to ensure that the infusion bottle is stably fixed in a complex environment;

[0048] Infusion tube arrangement

[0049] The infusion catheter is passed through the fixing sleeve 32 of the pipeline collection component 21. According to the length and position requirements of the infusion tube, the motor B24 is started through the control panel 3. When the motor B24 is started, its output shaft drives the bidirectional screw 25 to rotate, and the threaded sleeve 26 makes a linear motion on the screw, and drives the slide rod 28 to move synchronously through the L-shaped connecting plate 27. The sliding sleeve 30 on the outside of the slide rod 28 slides smoothly along the bottom groove of the guide frame 23 to ensure that the movement trajectory of the fixing sleeve 32 is controllable. This structural design enables the fixing sleeve 32 to flexibly adjust its position according to the actual length requirements of the infusion tube, and fix the infusion tube in an orderly manner in the transparent frame 35, effectively preventing the infusion tube from contacting external obstacles or being touched by people. Accidental pulling of the limbs of the staff; in particular, the spring frame 29 is sleeved on the outside of the slide bar 28, and its two ends are fixedly connected to the L-shaped connecting plate 27 and the sliding sleeve 30 respectively; when the infusion tube is pulled by external force, the spring frame 29 absorbs and disperses the impact force through elastic deformation, so that the clamping sleeve 32 can maintain the fixation of the infusion tube while allowing elastic displacement within a certain range; this elastic buffering mechanism can not only prevent the infusion tube from breaking due to rigid fixation, but also avoid damage to the blood vessels at the puncture site due to excessive pulling, significantly reducing the incidence of complications such as leakage and hematoma; in complex scenarios such as bumpy ambulances and field rescue, this design can effectively protect the integrity of the infusion pipeline system and ensure the safety and reliability of the treatment process;

[0050] Temperature regulation

[0051] When performing infusion in a cold environment, the temperature sensing device monitors the temperature data in the placement frame 4 in real time and feeds the data back to the control panel 3; the control panel 3 automatically controls the working state of the heater 15 according to the preset temperature range; the heat generated by the heater 15 is evenly conducted to the placement frame 4 through the heat pipe 16, warming the infusion bottle body, so that the infusion liquid is kept within the appropriate temperature range, ensuring a safe and comfortable infusion process.

[0052] It should be understood that the embodiments of the present application are not limited to the precise structures described above and shown in the drawings, and various modifications and changes can be made without departing from the scope thereof. The scope of the embodiments of the present application is limited only by the appended claims.

[0053] The above-described embodiments merely represent several implementation methods of the embodiments of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that a person skilled in the art may make various modifications and improvements without departing from the concept of the embodiments of the present application, and these modifications and improvements fall within the scope of protection of the embodiments of the present application.
