Description

A traditional Chinese medicine fumigation device for the care of pressure ulcers in critically ill bedridden patients. Technical Field

[0001] This invention relates to the field of pressure ulcer care equipment application technology, specifically a traditional Chinese medicine fumigation device for pressure ulcer care of critically ill bedridden patients. Background Technology

[0002] Pressure ulcers (also known as bedsores) are a common complication of severely bedridden patients. Because patients maintain a fixed position for a long time, the local skin tissue is subjected to pressure, ischemia, and hypoxia, which can easily lead to ulceration and infection. This not only increases the patient's pain but also prolongs the recovery period and may even cause serious complications such as sepsis. Therefore, in order to reduce the harm of pressure ulcers to bedridden patients, it is usually necessary to use traditional Chinese medicine fumigation equipment for daily care of the pressure ulcer site.

[0003] However, existing herbal fumigation equipment for pressure ulcer care in critically ill bedridden patients still has significant shortcomings. Most of these devices are fixed structures, large in size, and difficult to move, making them unsuitable for bedside care scenarios. They lack precise position adjustment functions, preventing targeted fumigation of the pressure ulcer area. Furthermore, the heating and mixing of the herbal solution in these devices is uneven, leading to unstable steam efficacy and potential issues such as localized burns or insufficient efficacy. Additionally, existing herbal fumigation equipment requires regular patient repositioning, which is often difficult for critically ill patients to do, and frequent repositioning increases the physical burden on caregivers and may affect the stability of the patient's condition. Summary of the Invention

[0004] The purpose of this invention is to address the problems of existing traditional Chinese medicine fumigation devices for the care of pressure ulcers in critically ill bedridden patients, which are mostly fixed structures, large in size, inconvenient to move, difficult to adapt to bedside care scenarios, lack precise position adjustment functions, and cannot perform targeted fumigation on the pressure ulcer area; furthermore, the heating and mixing uniformity of the traditional Chinese medicine solution in existing devices is poor, resulting in unstable steam efficacy and easy problems such as local burns or insufficient efficacy; secondly, existing devices require regular assistance in turning the patient, but critically ill patients cannot cooperate, and frequent turning increases the physical burden on caregivers and may affect the stability of the patient's condition. Therefore, this invention proposes a traditional Chinese medicine fumigation device for the care of pressure ulcers in critically ill bedridden patients.

[0005] The objective of this invention can be achieved through the following technical solution: a traditional Chinese medicine fumigation device for the care of pressure ulcers in critically ill bedridden patients, comprising a movable base, a storage mechanism, a conduit, a steam mechanism, an adjustment mechanism, a shifting mechanism, and a height adjustment mechanism. The storage mechanism is located in the middle of the movable base and has a material tank on it. The bottom of one end of the steam mechanism has an atomizing nozzle. The adjustment mechanism is located at the top of the movable base and has a sliding seat at its top. The shifting mechanism is located on one side of the sliding seat. The height adjustment mechanism is located on the side of the shifting mechanism away from the adjustment mechanism and has a sliding plate at its bottom. The steam mechanism is located on one side of the sliding plate.

[0006] Preferably, the storage mechanism is provided with a support frame at the bottom, which is welded to the movable base. The movable base is provided with casters at the four corners of the bottom. The material bucket is located in the middle of the support frame. A material inlet is provided on one side of the top of the material bucket, and a drain outlet is provided at the bottom of the material bucket. One end of the conduit is connected to the drain outlet.

[0007] Preferably, a mixing unit is provided in the middle of the material barrel, a first motor is installed on the top of the mixing unit, a rotating rod is movably connected to the bottom of the first motor through a rotating shaft, a heating block is provided at the bottom of the rotating rod, and several impellers are welded axially at equal intervals on the heating block.

[0008] Preferably, a second motor is installed at one end of the steam mechanism, and a water pump is movably connected to one end of the second motor via a rotating shaft. One end of the conduit is connected to the water pump, and the atomizing nozzle is installed at the bottom of the water pump.

[0009] Preferably, the adjustment mechanism has a base plate at the bottom, a push-pull unit at one end of the top of the base plate, a support plate at the bottom of the push-pull unit, a third motor installed on one side of the top of the support plate, a turntable movably connected to one end of the third motor via a rotating shaft, the turntable having a cylindrical structure, a connecting plate connected to one side of the turntable via a rotating shaft, a guide rod hinged to one end of the connecting plate, a support block welded to the top of the support plate, a sliding hole adapted to the guide rod being opened in the middle of the support block, and one end of the guide rod being welded to the slide block.

[0010] Preferably, the top two sides of the base plate near the support plate are bolted to the first slide rails, and the two first slide rails are fitted with first sliders, the tops of the two first sliders being welded to the bottom of the slide block.

[0011] Preferably, a first electric cylinder is provided at one end of the shifting mechanism, a first push rod is connected to the other end of the first electric cylinder, and a push plate is welded to one end of the first push rod.

[0012] Preferably, a stop is provided on one side of the height adjustment mechanism, a second electric cylinder is bolted to the top of the stop, a second push rod is connected to the bottom of the second electric cylinder, the second push rod is bolted to the slide plate, a second slide rail is bolted to the side of the stop near the slide plate, a second slider is connected to the second slide rail, and the slide plate is bolted to the second slider.

[0013] Preferably, the method of using the fumigation equipment specifically includes the following steps:

[0014] Step 1: Move the device to the side of the bedridden patient using the movable base. The first electric cylinder on the displacement mechanism drives the first push rod to move, and the second electric cylinder on the height adjustment mechanism drives the second push rod to move up and down. Adjust the left and right position and height of the steam mechanism to bring the atomizing nozzle close to the patient's pressure ulcer.

[0015] Step 2: Turn on the first motor on the mixing unit. The first motor drives the heating block at the bottom of the rotating rod to rotate, so that several impellers heat and stir the Chinese medicine liquid in the material tank. In conjunction with turning on the water pump of the steam mechanism, the Chinese medicine liquid sprayed from the atomizing nozzle is used to fumigate and care for the patient's pressure sore.

[0016] Step 3: Turn on the third motor on the push-pull unit. The third motor drives the connecting plate on the turntable to move, and the slide at one end of the guide rod moves left and right, causing the atomizing nozzle to move back and forth. In conjunction with turning on the second motor, the second motor drives the atomizing nozzle at the bottom of the water pump to rotate, so as to repeatedly fumigate and care for different locations of the patient's pressure ulcers.

[0017] The beneficial effects of this invention are:

[0018] 1. The heating and stirring unit of the storage mechanism processes the Chinese medicine liquid into a uniformly warm liquid. The impeller rotates at high speed with the rotating rod to achieve uniform mixing and heating of the liquid, avoiding local overheating and uneven efficacy. This realizes the integrated "heating + stirring" design of the Chinese medicine liquid, which does not require additional equipment and simplifies the Chinese medicine pretreatment process. The liquid is then transported to the water pump of the steam mechanism through a conduit, and then converted into steam through an atomizing nozzle. The three work together to realize the automated process of "Chinese medicine pretreatment → liquid delivery → steam generation", which does not require frequent manual operation, reduces the physical exertion of nursing staff, improves nursing efficiency, and ensures stable steam efficacy.

[0019] 2. The horizontal adjustment mechanism adjusts the horizontal position of the steam mechanism, the vertical adjustment mechanism adjusts its height, and the overall adjustment mechanism drives the reciprocating movement. The three mechanisms work together to achieve precise positioning and uniform sweeping of the steam mechanism in "three-dimensional space". This can adapt to different pressure ulcer sites of patients (such as large pressure ulcers on the back and local pressure ulcers on the buttocks) and avoid concentrated steam stimulation of the wound, thus improving nursing safety. At the same time, the sliding block of the adjustment mechanism is linked with the electric cylinder assembly of the horizontal and vertical adjustment mechanisms to ensure the stability of movement in all dimensions, avoid equipment shaking that causes the steam nozzle to deviate, and further improve the accuracy of fumigation.

[0020] 3. The mobile base supports all mechanisms for material storage, adjustment, and relocation. Combined with casters, it enables flexible movement of the entire device, allowing for quick connection to critically ill patients in different beds. Furthermore, the stable structure of the mobile base provides support for the linkage of various mechanisms, ensuring that there is no risk of tipping over during movement and adjustment. It balances "flexibility" and "stability." Through the cooperation between various mechanisms, patients do not need to get up, making it suitable for the nursing scenarios of critically ill bedridden patients and reducing the pain caused by changes in body position.

Detailed Implementation

[0031] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please refer to Figures 1-8. A traditional Chinese medicine fumigation device for pressure ulcer care in critically ill bedridden patients includes a movable base 1, a storage mechanism 2, a conduit 3, a steam mechanism 4, an adjustment mechanism 5, a shifting mechanism 6, and a height adjustment mechanism 7. The storage mechanism 2 is located in the middle of the movable base 1 and has a material tank 202. The bottom of one end of the steam mechanism 4 is equipped with an atomizing nozzle 403. The adjustment mechanism 5 is located on the top of the movable base 1 and has a slide 505 on its top. The shifting mechanism 6 is located on one side of the slide 505. The height adjustment mechanism 7 is located on the side of the shifting mechanism 6 away from the adjustment mechanism 5 and has a sliding plate 704 at its bottom. The steam mechanism 4 is located on one side of the sliding plate 704.

[0033] An infrared sensor (model: ACS724LLCTR-05AB-T, manufacturer: Shenzhen Rongshengtai Technology Co., Ltd.) is installed on one side of the sliding plate 704, and a PLC controller (model: SP-PDG, manufacturer: Wenzhou Hannai Enterprise Management Co., Ltd.) is installed at the bottom of the mobile base 1. The infrared sensor acquires the location of the pressure ulcers of the bedridden patient and transmits the acquired information to the PLC controller. The PLC controller controls the various mechanisms to work together to realize the automated traditional Chinese medicine fumigation process for the pressure ulcers of the bedridden patient, reduce human intervention, and thus improve the efficiency of traditional Chinese medicine fumigation for the pressure ulcers of the patient.

[0034] In one optional embodiment of the present invention, a support frame 201 is provided at the bottom of the storage mechanism 2. The support frame 201 is welded to the movable base 1. The movable base 1 is provided with casters at all four corners of its bottom. The casters enable the equipment to move flexibly and can be easily pushed to the bedside of critically ill patients, adapting to different ward and bed layouts and reducing the burden of carrying by nursing staff. The feed tank 202 is located in the middle of the support frame 201. The feed tank 202 can store a sufficient amount of traditional Chinese medicine liquid. A feed inlet 203 is provided on one side of the top of the feed tank 202, and a drain outlet 204 is provided at the bottom of the feed tank 202. One end of the conduit 3 is connected to the drain outlet 204. The feed inlet 203 facilitates the addition of medicinal materials and liquid, and the drain outlet 204 facilitates cleaning after use, reducing the frequency of consumable replacement.

[0035] In one optional embodiment of the present invention, a mixing unit 205 is provided in the middle of the material tank 202. A first motor 2051 is installed on the top of the mixing unit 205. A rotating rod 2052 is movably connected to the bottom of the first motor 2051 through a rotating shaft. A heating block 2053 is provided at the bottom of the rotating rod 2052. The heating block 2053 can heat the medicinal liquid at a constant temperature to ensure the stable steam temperature required for fumigation. Several impellers 2054 are welded axially at equal intervals on the heating block 2053. The impellers 2054 rotate at high speed with the rotating rod 2052 to achieve uniform mixing and heating of the medicinal liquid, avoiding local overheating of the medicinal liquid and uneven efficacy.

[0036] In one optional embodiment of the present invention, a second motor 401 is installed at one end of the steam mechanism 4, and a water pump 402 is movably connected to one end of the second motor 401 via a rotating shaft. One end of the conduit 3 is connected to the water pump 402, and an atomizing nozzle 403 is installed at the bottom of the water pump 402. The water pump 402 draws the medicine liquid from the storage mechanism 2 through the conduit 3, and the atomizing nozzle 403 converts the medicine liquid into fine steam, which not only improves the skin's absorption efficiency of the Chinese medicine ingredients, but also avoids direct contact of the liquid with the pressure ulcer wound, thus preventing irritation and infection. At the same time, the second motor 401 drives the atomizing nozzle 403 to rotate, which is beneficial for the atomizing nozzle 403 to perform Chinese medicine fumigation on the more sensitive areas of the pressure ulcer.

[0037] In an optional embodiment of the present invention, the adjusting mechanism 5 has a base plate 501 at its bottom, a push-pull unit 502 at one top end of the base plate 501, a support plate 5021 at the bottom of the push-pull unit 502, a third motor 5022 mounted on one side of the top of the support plate 5021, a turntable 5023 movably connected to one end of the third motor 5022 via a rotating shaft, the turntable 5023 having a cylindrical structure, a connecting plate 5024 connected to one side of the turntable 5023 via a rotating shaft, a guide rod 5025 hinged to one end of the connecting plate 5024, and a support block 5026 welded to the top of the support plate 5021. The third motor 5022 drives the guide rod 5025 to slide back and forth, causing the slide block 505 and the upper mechanism to move at a uniform speed, achieving a "sweeping" effect of steam on the pressure ulcer area. Even steaming is provided to avoid excessive local steam accumulation that could burn the skin. The support block 5026 has a sliding hole in the middle that matches the guide rod 5025. One end of the guide rod 5025 is welded to the slide block 505.

[0038] In one optional embodiment of the present invention, the top two sides of the base plate 501 near the support plate 5021 are bolted together with first slide rails 503. Each of the two first slide rails 503 is connected with a first slider 504. The top of each of the two first sliders 504 is welded to the bottom of the slide block 505, and slides with the slide block 505 to reduce frictional resistance, ensure smooth and uninterrupted movement, and improve the accuracy of the fumigation position.

[0039] In one optional embodiment of the present invention, a first electric cylinder 601 is provided at one end of the displacement mechanism 6. The first electric cylinder 601 is connected to an external power source. A first push rod 602 is connected to one end of the first electric cylinder 601. A push plate 603 is welded to one end of the first push rod 602. The push plate 603 is welded to the baffle 701. The push plate 603 is moved by the extension and retraction of the first electric cylinder 601, which can adjust the position of the height adjustment mechanism 7 and the steam mechanism 4 laterally to adapt to the pressure ulcer areas of patients of different body types (such as the back, buttocks, and other different parts), thus expanding the applicability of the equipment.

[0040] In one optional embodiment of the present invention, a baffle 701 is provided on one side of the height adjustment mechanism 7. A second electric cylinder 702 is bolted to the top of the baffle 701, and a second push rod 703 is connected to the bottom of the second electric cylinder 702. The second push rod 703 is bolted to the slide plate 704. The height of the slide plate 704 can be precisely adjusted by extending and retracting the second electric cylinder 702 to adapt to different bed heights / patient positions (such as semi-recumbent and supine positions), ensuring the optimal distance between the atomizing nozzle 403 and the pressure ulcer area. A second slide rail 705 is bolted to the side of the baffle 701 near the slide plate 704, and a second slider 706 is connected to the second slide rail 705. The slide plate 704 is bolted to the second slider 706, and the height adjustment is improved by raising and lowering the slide plate 704, thus preventing the steam mechanism 4 from shaking and affecting the fumigation effect.

[0041] In use, firstly, the device is moved to the side of the bedridden patient by moving the base 1. The first electric cylinder 601 on the shifting mechanism 6 drives the first push rod 602 to move, and the second electric cylinder 702 on the height adjustment mechanism 7 drives the second push rod 703 to move up and down, adjusting the left and right position and height of the steam mechanism 4, and bringing the atomizing nozzle 403 close to the patient's pressure ulcer, so as to achieve precise positioning and uniform sweeping of the steam mechanism 4 in "three-dimensional space" and adapt to the pressure ulcer sites of different patients.

[0042] Then, the first motor 2051 on the mixing unit 205 is turned on. The first motor 2051 drives the heating block 2053 at the bottom of the rotating rod 2052 to rotate, so that several impellers 2054 heat and stir the Chinese medicine liquid in the material tank 202 to ensure the stability of the steam efficacy. In conjunction with turning on the water pump 402 on the steam mechanism 4, the Chinese medicine liquid sprayed by the atomizing nozzle 403 is used to fumigate and care for the patient's pressure sore.

[0043] Finally, the third motor 5022 on the push-pull unit 502 is activated. The third motor 5022 drives the connecting plate 5024 on the turntable 5023 to move, and the slide 505 at one end of the guide rod 5025 moves left and right, causing the atomizing nozzle 403 to reciprocate left and right. In conjunction with activating the second motor 401, the second motor 401 drives the atomizing nozzle 403 at the bottom of the water pump 402 to rotate, so as to repeatedly fumigate and care for different locations of the patient's pressure ulcers, avoiding concentrated steam stimulation of the wound and improving the safety of care.

[0044] The preferred embodiments of the present invention disclosed above are merely illustrative of the invention. These preferred embodiments do not exhaustively describe all details, nor do they limit the invention to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of the invention, thereby enabling those skilled in the art to better understand and utilize the invention.
