Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to an infusion device for field use in high-altitude cold regions. Background Art

[0002] The altitude in high-altitude cold regions is above 3500 meters, with a cold climate. The lowest temperature in winter reaches below -40°C, and the night temperature in summer is also around -6°C.

[0003] As a commonly used clinical treatment method, infusion therapy has the advantages of quick effect, simple operation, and good life support effect in emergency situations. In field rescue and wartime rescue in high-altitude cold regions, special attention should be paid to infusion therapy. In the extreme environment of high-altitude cold regions, when facing the wounded, it is not possible to directly infuse overly cold liquid, which is likely to take away the little remaining body temperature of the wounded. Infusing low-temperature liquid causes strong pain and may even trigger arrhythmia in the wounded, endangering the life safety of the wounded. And it takes a long time and is very inconvenient to warm up the stored infusion bag after taking it out. Summary of the Invention

[0066] See Figures 1 to 10This embodiment provides an infusion device for outdoor use in plateau cold regions, including a storage cylinder 10, a first partition 20 and a heating mechanism 30.

[0067] One end of the storage cylinder 10 is closed, and the other end of the storage cylinder 10 is open.

[0068] The first partition 20 is arranged in the storage tube 10, and a constant temperature chamber 11 that can be opened and closed is formed between the first partition 20 and the closed end of the storage tube 10. The specific first partition 20 divides the internal space of the erected storage tube 10 in half. Compared with the low temperature in the cold plateau area, the temperature in the constant temperature chamber 11 is suitable for storing infusion bags (for example, the temperature in the cold plateau area is -40°C, and the infusion bag is easy to freeze at this temperature. The temperature in the constant temperature chamber 11 can be adjusted to preserve the infusion bag). A window 16 is provided on the side wall of the storage tube 10, and a closed cover is connected to the window 16. The closed cover can be threaded to close the window 16, so that the constant temperature chamber 11 can be opened and closed. A heating bag (not shown) or a heating pad (not shown) and other structures are arranged on the inner wall of the constant temperature chamber 11, which can heat the infusion bag placed in the constant temperature chamber 11. In order to make the heating temperature suitable, a temperature sensor can be placed in the constant temperature chamber 11, and the temperature sensor is connected to a PLC controller. According to the data from the temperature sensor, a PLC controller is used to control structures such as a heating bag or a heating pad to keep the infusion bag warm.

[0069] The heating mechanism 30 is located outside the open end of the storage tube 10 and can slide close to or away from the storage tube 10 to heat the infusion bag. The infusion bag taken out from the constant temperature chamber 11 is placed in the heating mechanism 30 for heating so that the temperature of the liquid in the infusion bag is suitable before it is injected into the human body.

[0070] When the closed end of the storage tube 10 is placed on the ground, the temperature-raising mechanism 30 is raised when it is away from the storage tube 10 so that the liquid in the infusion bag therein can be transported to the human body via the infusion device. Infusion requires a certain height. Ordinary infusion is achieved by an infusion stand. In field rescue or wartime rescue, the infusion stand is inconvenient to carry. After the storage tube 10 is placed vertically, the temperature-raising mechanism 30 is raised, and the infusion stand is carried, so that the height of the infusion bag therein is increased, and the liquid in the infusion bag can flow out normally and be infused into the wounded body. The temperature-raising mechanism 30 can always have an infusion bag. When not in use, the temperature-raising mechanism 30 does not heat up the infusion bag, so that the temperature of the infusion bag is the same as that of the infusion bag in the constant temperature chamber 11. When in use, the temperature-raising mechanism 30 heats up the infusion bag therein.

[0071] In this embodiment, the infusion bag is stored in the constant temperature chamber 11, heated by the heating mechanism 30 and then infused into the wounded. There is no need to prepare an additional infusion bag heating device, which makes the operation more convenient. The storage cylinder 10 can store the infusion bag and the infusion set. The storage cylinder 10 and the heating mechanism 30 form an infusion stand. The whole structure is compact, with a high degree of integration, easy to carry and use.

[0072] In one embodiment, a second storage chamber 12 is formed between the partition plate and the open end of the storage cylinder 10. The heating mechanism 30 can seal the open end of the storage cylinder 10.

[0073] In this embodiment, the infusion bag is placed in the constant temperature chamber 11, and the infusion set can be placed in the second storage chamber 12. The purpose of separating the two is that the infusion set has no temperature requirement. After separation, the overall volume of the constant temperature chamber 11 is reduced, thus reducing energy consumption and extending the field preservation time.

[0074] In one embodiment, a second partition plate 21 is provided in the storage cylinder 10; the second partition plate 21 is arranged along the axial direction of the storage cylinder 10; a third chamber 13 is formed between the second partition plate 21 and the inner wall of the storage cylinder 10.

[0075] The infusion device for use in high-altitude cold regions in the wild further includes a motor 40, a driving rod 41 and a driving column 42.

[0076] The motor 40 is arranged in the third chamber 13 and is close to the closed end of the storage cylinder 10. The driving rod 41 is arranged along the axial direction of the storage cylinder 10, and one end of the driving rod 41 is coaxially connected to the output end of the motor 40. The driving column 42 is slidably arranged along the axial direction of the storage cylinder 10 in the third chamber 13, and a driving hole 421 is formed therein. The driving rod 41 is threadedly connected to the driving hole 421. One end of the driving column 42 away from the motor 40 is connected to the heating mechanism 30. Specifically, grooves are formed on the inner walls on both sides of the third chamber 13, and strip-shaped protrusions are respectively arranged on both sides of the driving column 42. The strip-shaped protrusions are slidably matched with the corresponding grooves, so as to realize the sliding of the driving column 42 in the third chamber 13.

[0077] In this embodiment, the motor 40 drives the driving rod 41 to rotate, so that the driving column 42 slides in the third chamber 13, and further drives the heating mechanism 30 to move away from or close to the storage cylinder 10.

[0078] In one embodiment, an openable and closable ventilation hole 422 is formed on the driving column 42. The ventilation hole 422 is communicated with the driving hole 421.

[0079] The heating mechanism 30 includes a heating housing 31 and a heating assembly 32.

[0080] The heating assembly 32 includes an elastic heating bladder 321, a connecting pipe 322 and a heating component.

[0081] The heating-up housing 31 has an openable and closable fourth chamber 17, and the fourth chamber 17 communicates with the driving hole 421. The elastic heating-up bladder 321 is filled with a heat-conducting liquid. The lower end of the elastic heating-up bladder 321 is concave to accommodate the infusion bag. The upper end of the connecting pipe 322 is connected to the inner wall of the upper end of the heating-up housing 31, and the lower end of the connecting pipe 322 passes through the elastic heating-up bladder 321 and is used to lift the infusion bag. The heating component is used to heat the heat-conducting liquid in the elastic heating-up bladder 321. A temperature sensor is arranged in the elastic heating-up bladder 321. The temperature sensor is externally connected to a PLC controller and is powered by a power supply. The above two work, so as to ensure that the temperature of the heat-conducting liquid in the elastic heating-up bladder 321 is controllable. The heating component adopts the prior art. For example, an electric heating element can be used to heat the heat-conducting liquid in the elastic heating-up bladder 321, and the heat-conducting liquid can be water. The elastic heating-up bladder 321 can be regarded as a housing with an open lower end. The inner part of the wall of the housing is hollow to be filled with the heat-conducting liquid, and the elastic heating-up bladder 321 is elastic.

[0082] In this embodiment, when the casualty loses too much body fluid, such as hemorrhagic shock, etc. It is necessary to quickly transfuse blood or replenish fluids. In order to speed up the blood transfusion or infusion speed, it is necessary to pressurize the infusion bag.

[0083] The infusion bag is placed in the elastic heating-up bladder 321. The infusion set passes through the heating-up housing 31 and is connected to the infusion bag. The infusion bag is hung on the connecting pipe 322. When the heating-up housing moves away from the storage cylinder 10, the ventilation hole 422 opens, and the external air flows into the heating-up housing 31 through the ventilation hole 422 and the driving hole 421. When the heating-up housing 31 descends, the ventilation hole 422 closes. At this time, the driving rod 41 moves in the driving hole 421, so as to squeeze the air in the heating-up housing 31, and then make the elastic heating-up bladder 321 squeeze the infusion bag inward, realizing pressurization of the infusion bag. The driving rod 41 drives the driving column 42 to move to achieve two functions. One is to drive the heating-up housing 31 to rise and fall, so that the infusion bag is at a higher position for easy infusion; the other is that when the driving column 42 retracts into the third chamber 13, the ventilation hole 422 is closed, and the infusion bag can be pressurized.

[0084] In one embodiment, the heating-up housing 31 includes a bottom plate 311 and a top cover 312.

[0085] The bottom plate 311 is connected to the driving column 42. A connecting hole 314 communicating with the driving hole 421 is opened thereon. An installation hole 313 penetrating through is also opened on the bottom plate 311. The lower end of the elastic heating-up bladder 321 is concave and buckled at the orifice of the installation hole 313, so that the elastic heating-up bladder 321 isolates the air in the fourth chamber 17 from the air at the installation hole 313. The top cover 312 covers the bottom plate 311. A fourth chamber 17 is formed between the top cover 312 and the bottom plate 311, and the top cover 312 and the bottom plate 311 are fixedly connected.

[0086] The heating component 32 further includes a sealing plate 323, a connecting rod 324, a hook 325 and a baffle 326.

[0087] A relief hole is formed in the sealing plate 323, and the sealing plate 323 can seal the port of the mounting hole 313 away from the top cover 312. One end of the connecting rod 324 passes through the relief hole and the mounting hole 313 in sequence and is threadedly connected to the inner wall of the connecting pipe 322. The hook 325 is arranged at one end of the connecting rod 324 close to the connecting pipe 322, and the hook 325 is used for hooking the infusion bag. The baffle 326 is connected to the connecting rod 324, and the baffle 326 abuts against one end of the sealing plate 323 away from the bottom plate 311. An external connection hole 327 through which the end of the infusion bag can extend is formed in the sealing plate 323.

[0088] In this embodiment, after the connecting rod 324 is rotated, the baffle 326 and the sealing plate 323 on the connecting rod 324 are removed together, and the infusion bag hooked on the hook 325 at the upper end of the connecting rod 324 can also be removed. The infusion set is communicated with the infusion bag by piercing the part of the infusion bag extending out of the external connection hole 327.

[0089] In one embodiment, a third partition plate 22 is connected to the bottom plate 311. The third partition plate 22 divides the fourth chamber 17 into two chambers, and both chambers are communicated with the connection hole 314.

[0090] Two mounting holes 313 are formed in the bottom plate 311; the two mounting holes 313 are respectively located on both sides of the third partition plate 22. Two sets of heating components 32 are provided and are arranged corresponding to the two mounting holes 313.

[0091] In this embodiment, when the wounded need to have pressure infusion, it means the situation is relatively urgent. The two sets of heating components 32 can heat the two infusion bags simultaneously. When one infusion bag is infused completely, the infusion set can be connected to another infusion bag for infusion.

[0092] In addition, when one infusion bag is under pressure, the other infusion bag is also wrapped by the elastic heating bladder 321 at the same time. And because the air pressure in the heating housing 31 increases at this time, the elastic heating bladder 321 fits more closely with the infusion bag, so that the heat transfer is more sufficient, the heating efficiency of the infusion bag is higher, which is beneficial to the treatment of critically wounded patients.

[0093] In one embodiment, the outer end of the vent hole 422 has a gradually decreasing diameter and is inclined downward; a plug pin 50 is slidably arranged on the driving column 42; one end of the plug pin 50 has a gradually decreasing size and can be inserted into the small end of the vent hole 422 to block the vent hole 422; the plug pin 50 is inclined. Specifically, vent holes 422 and placement holes are respectively formed on both sides of the driving hole 421. The vent hole 422 and the mounting hole 313 are coaxial. The large-diameter end of the plug pin 50 is located in the placement hole, and the small-diameter end of the plug pin 50 is located in the vent hole 422. The plug pin 50 can slide obliquely in the placement hole and the vent hole 422.

[0094] The heating mechanism 30 further includes a magnetic block 33 suspended below the bottom plate 311. The magnetic block 33 can be clamped on the driving column 42. The magnetic block 33 can magnetically attract the plug pin 50. When it is necessary for the small-diameter end of the plug pin 50 to be far away from the small-diameter end of the vent hole 422, the magnetic block 33 can be clamped on one side of the large-diameter end of the plug pin 50 to magnetically attract the plug pin 50, so that the plug pin 50 slides towards the placement hole, thereby allowing air to flow from the vent hole 422 into the driving hole 421.

[0095] In one embodiment, a plurality of threaded holes 14 are formed in the closed end of the storage cylinder 10. The infusion device for use in the high-altitude cold region in the wild further includes a plurality of support rods 60; the ends of the support rods 60 can be threadedly connected to the threaded holes 14. Specifically, a plurality of support rod placement holes 15 along the axial direction of the storage cylinder 10 are further formed on the storage cylinder 10, and the support rod placement holes 15 are used for storing the support rods 60.

[0096] In this embodiment, the storage cylinder 10 together with the heating mechanism 30 is integrally in the shape of a capsule for easy carrying. When placed, after the support rod 60 is connected to the threaded hole 14 of the storage cylinder 10, the lower end of the support rod 60 can be inserted into the ground to fix the storage cylinder 10.

However, it can be understood that the embodiments of the present invention can be practiced without these specific details.
