Description

Technical Field

[0001] This invention relates to the field of infusion device technology, and more particularly to an infusion device for a hyperbaric oxygen chamber. Background Technology

[0002] Hyperbaric oxygen therapy involves placing patients in a hyperbaric oxygen chamber for pressurization and oxygen inhalation to treat diseases. Intravenous infusion care within the chamber is receiving increasing attention because the environment inside the chamber differs greatly from normal pressure. During the pressurization phase, gas expansion can easily occur in the infusion bottle and drip chamber, posing a risk of air embolism. Currently, the mainstream clinical approach is to use an infusion bottle with an open infusion method. A long venting needle connects the gas inside the bottle with that inside the chamber to balance the pressure and prevent the infusion bottle from exploding. At the same time, the liquid level and drip rate of the Murphy drip chamber are manually adjusted to suit different treatment stages.

[0003] Existing high-pressure infusion equipment suffers from insufficient reliability in pressure balance. Because long needles need to be inserted to the bottom of the infusion bottle for effective pressure adjustment, pressure balance often fails due to the inability to insert the needle to the bottom. It is difficult to adapt to the dynamic pressure inside the chamber and poses high safety risks. Open-type infusion requires frequent replacement of long venting needles, which can easily allow air to enter the tubing and cause embolism. Furthermore, the flow rate is difficult to control, and it is difficult to accurately control the flow rate when changing needles. The lack of automatic pressure compensation protection functions for the chamber environment poses safety hazards. Summary of the Invention

[0027] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0028] Example 1, referring to Figure 1 - Figure 2 The first embodiment of the present invention provides an infusion device for a hyperbaric oxygen chamber. The device includes: a fixing frame 1 for supporting the overall equipment, a medicine bag 2 for storing medicine, an infusion unit 3 for conveying medicine, and a pressure regulating unit 4 for adjusting the air pressure; the fixing frame 1 is provided with a medicine bag 2, the infusion unit 3 is slidably disposed through the medicine bag 2, and the pressure regulating unit 4 is slidably installed through the medicine bag 2 and slidably mounted on the medicine bag 2, and the pressure regulating unit 4 is slidably connected to the fixing frame 1.

[0029] The medicine bag 2 includes a guide tube 31 that runs through and slides on the medicine bag 2 for initial delivery of the medicine; a tie tube 32 fixedly installed on the guide tube 31 for connecting the medicine bag 2; a dripping device 33 fixedly installed at the bottom of the tie tube 32 for buffering the medicine; a stop clamp 34 fixedly installed on the outer wall of the guide tube 31 for stopping the medicine; a protective assembly 35 fixedly installed on the guide tube 31 for filtering and separating the medicine; a delivery part 36 fixedly installed on the protective assembly 35 for venting gas; an infusion tube 37 fixedly installed on the protective assembly 35 for complete delivery of the medicine; and a needle 38 fixedly installed at the other end of the infusion tube 37 for connecting to the patient's blood vessel.

[0030] Furthermore, the pressure regulating unit 4 includes a PCL connecting pipe 41 that passes through and slides on the medicine bag 2 for connecting the medicine bag 2; a control valve 43 that is fixedly installed on the PCL connecting pipe 41 for controlling the opening and closing of the PCL connecting pipe 41; a pressure gauge 44 that is fixedly installed on the PCL connecting pipe 41 for observing the air pressure; an airbag assembly 45 that is fixedly installed on the PCL connecting pipe 41 for controlling the pressure of the medicine bag 2; and a fixing buckle 42 that slides on the PCL connecting pipe 41, and the fixing buckle 42 is fixedly connected to the fixing frame 1 for connecting and fixing the PCL connecting pipe 41.

[0031] During use, when administering intravenous fluids to a patient inside the hyperbaric oxygen chamber, the PCL connecting tube 41 is inserted into the medicine bag 2. The medicine bag 2 is then placed inside the hyperbaric oxygen chamber. Because the air pressure inside the medicine bag 2 differs from the air pressure inside the chamber, the medicine bag 2 initially deforms due to the pressure difference. Simultaneously, by opening the control valve 43 and the airbag assembly 45, the air pressure inside the medicine bag 2 is brought into contact with and exchanged with the air pressure inside the hyperbaric oxygen chamber, ensuring that the air pressure inside the medicine bag 2 matches that inside the chamber, preventing the medicine bag 2 from rupturing due to pressure deformation. Then, the ligating tube 32 is inserted into the medicine bag 2, and simultaneously... The pressure inside the medicine bag 2 is changed by controlling the airbag assembly 45, causing the medicine in the medicine bag 2 to fall into the dripping device 33 through the ligature 32 and guide tube 31. The medicine then enters the protective assembly 35, which separates the medicine, allowing the gas in the medicine to be discharged through the delivery section 36. The purified medicine then enters the infusion tube 37 through the separation of the protective assembly 35, reaching the needle 38. The infusion is then started by inserting the needle 38 into the patient's blood vessel. The infusion rate can be controlled by squeezing the airbag assembly 45, effectively improving the safety, stability, and convenience of hyperbaric oxygen chamber infusion.

[0032] Example 2, refer to Figure 1 - Figure 7 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the airbag assembly 45 includes a mounting member 451 fixedly mounted on the PCL connecting pipe 41 for connecting the PCL connecting pipe 41, a squeezing member 452 fixedly mounted on the mounting member 451 for squeezing and buffering, and an airbag 453 fixedly mounted on the inner wall of the squeezing member 452. The airbag 453 penetrates and is connected to the mounting member 451 to pressurize the air.

[0033] Compared to Embodiment 1, further, a discharge valve 454 is installed through and fixedly mounted on the bottom of the extrusion member 452, and the discharge valve 454 is connected through and connected to the airbag 453 to release air pressure.

[0034] During use, when administering intravenous fluids to a patient inside the hyperbaric oxygen chamber, the medicine bag 2 is taken in from the outside. Because the air pressure inside the medicine bag 2 differs from the air pressure inside the hyperbaric oxygen chamber, the medicine bag 2 begins to deform. Simultaneously, by opening the control valve 43 and the discharge valve 454, the air pressure inside the medicine bag 2 exchanges with the air pressure inside the hyperbaric oxygen chamber, thus aligning the air pressure inside the medicine bag 2 with the external air pressure. Then, by squeezing the compression member 452, gas is delivered through the air bladder 453 inside the compression member 452, via PC. L-connector 41 delivers gas into the medicine bag 2, squeezing the liquid medicine inside and causing it to move towards the infusion unit 3 for intravenous infusion treatment. By squeezing the squeeze element 452 and the air bag 453 and closing the discharge valve 454, the air pressure inside the medicine bag 2 can be controlled in real time, thus controlling the delivery speed of the liquid medicine. The pressure gauge 44 can also monitor the air pressure inside the medicine bag 2 in real time, overcoming the shortcomings of traditional equipment in accurately controlling the flow rate and adapting to the needs of different treatment stages.

[0035] The remaining structure is the same as that in Example 1.

[0036] Example 3, referring to Figure 1 - Figure 8 This is the third embodiment of the present invention, which differs from the second embodiment in that: the protective component 35 includes a connector 352 fixedly installed on the guide tube 31 for connecting with the guide tube 31, a protective component 351 fixedly installed on the outer wall of the connector 352 for sealing the whole, a partition plate 354 fixedly installed on the inner wall of the protective component 351 for separation, an absorbent cloth 357 fixedly installed on the inner wall of the protective component 351 for preliminary filtration, and a filter cloth 358 fixedly installed on the inner wall of the protective component 351 for secondary filtration.

[0037] Compared to Embodiment 2, further, a separating rod 355 is fixedly installed on the separating plate 354 to guide the flow of the liquid medicine, and the separating rod 355 is fixedly connected to the protective member 351. A guide plate 356 is fixedly installed on the outer wall of the separating plate 354 to guide the dripping liquid medicine, and the guide plate 356 is fixedly connected to the protective member 351. A conical filter tube 353 is fixedly installed at the bottom of the connecting member 352, and the conical filter tube 353 is fixedly connected to the protective member 351 to perform preliminary separation of the liquid medicine.

[0038] Furthermore, the adjustment unit 359 includes a semi-circular plate 3591 fixedly installed on the inner wall of the protective member 351 for intercepting the liquid medicine, a movable member 3592 slidably installed inside the semi-circular plate 3591 for intercepting and adjusting the liquid medicine, a connecting airbag 3593 fixedly installed on the outer wall of the movable member 3592 for driving the semi-circular plate 3591, and a toothed plate 3595 fixedly installed on the top of the movable member 3592 for separating and conveying the liquid medicine.

[0039] Furthermore, the interior of the semi-circular plate 3591 is provided with a moving groove 3594, and the moving groove 3594 is slidably connected to the connecting airbag 3593 for guiding the movement of the connecting airbag 3593.

[0040] Furthermore, the conveying unit 36 ​​includes a connecting ring 361 fixedly installed on the inner wall of the protective component 351 for fixing; a first ventilated plate 362 fixedly installed on the inner wall of the connecting ring 361 for initial interception of the liquid medicine; a second ventilated plate 363 fixedly installed on the inner wall of the connecting ring 361 for secondary interception of the liquid medicine; a filter plate 364 fixedly installed on the inner wall of the connecting ring 361 for filtering the gas; and a dustproof plate 365 fixedly installed on the inner wall of the connecting ring 361 for preventing external dust and dirt from entering.

[0041] During use, when administering intravenous infusion to a patient in a hyperbaric oxygen chamber, the air pressure inside the medicine bag 2 is adjusted by the airbag assembly 45. This allows the medication inside the medicine bag 2 to flow through the guide tube 31 into the conical filter tube 353 inside the protective component 351. The conical filter tube 353 intercepts and separates the incoming medication, allowing it to flow through both sides of the conical filter tube 353 into the guide plate 356. Guided by the guide plate 356, the medication falls to the bottom of the protective component 351. As more medication falls, it overflows the separator rod 355 inside the protective component 351, causing the gas in the subsequent dripping medication to rise due to the separation of the liquid itself. The liquid begins to pass through the separator 355 into the interior of the adsorption cloth 357 and the filter cloth 358, and accumulates again at the semi-circular plate 3591. This isolates all the gas inside the liquid entering later at the upper part of the separator 354, completing the separation of the gas inside the liquid. As more and more liquid accumulates at the semi-circular plate 3591, it begins to spread over the toothed plate 3595 and falls into the infusion tube 37. It is then delivered to the patient through the infusion tube 37. Under the action of the liquid, the connecting airbag 3593 can slide in the moving groove 3594 with the moving part 3592 and the toothed plate 3595, thereby adjusting the separation speed and dripping speed of the liquid.

[0042] The separated gas is adsorbed by the air vents 362 and 363 inside the connecting ring 361, which condenses the moisture in the liquid medicine in the gas. This allows the gas to pass through while the liquid is adsorbed and condensed. The condensed liquid medicine falls back into the protective component 351, avoiding waste of the liquid medicine. Then the gas is discharged through the filter plate 364 and the dustproof plate 365, thus avoiding the risk of air embolism at the source and ensuring the treatment safety of critically ill or immunocompromised patients in the cabin.

[0043] The remaining structure is the same as that in Example 2.

[0044] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
