Description

Technical Field

[0001] This invention relates to the field of medical auxiliary devices, specifically to a burn medicated bath device. Background Technology

[0002] Burns are tissue damage caused by high temperatures, chemicals, or electric shocks. The severity of burns can be classified into four degrees based on local changes: First degree, congestion due to vascular paralysis; Second degree, formation of burn blisters filled with serum; Third degree, tissue necrosis; Fourth degree, tissue carbonization. After a burn, the skin, the body's natural barrier against microbial invasion, is destroyed, and the necrotic skin tissue becomes an excellent "culture medium" for microbial growth and reproduction. Therefore, burn wounds are highly susceptible to infection. Thus, burn patients need to pay close attention to skin cleaning and disinfection during treatment.

[0003] Traditional cleaning and disinfection methods involve wiping the affected area with medical cotton balls soaked in disinfectant or directly pouring disinfectant onto the area. However, these methods are time-consuming when the burn area is large. Furthermore, when the affected area has not fully scabbed over and pain persists, direct contact with medical cotton balls or similar materials will undoubtedly increase the patient's pain. Current research indicates that medicated baths are an important means of promoting healing and preventing infection in patients with wound infections, those for whom routine dressing changes cannot remove wound secretions, those with residual wounds in the later stages of burns, those before skin grafting, and those undergoing functional exercises after wound healing. Medicated baths also allow medication to quickly cover all wound surfaces, thereby relieving pain and reducing scarring.

[0004] When performing a medicated bath, a container is needed to dissolve the medicine in water to form a medicated solution, and then the affected area is immersed in the medicated solution. However, ordinary containers cannot maintain the appropriate temperature of the medicated solution for a long time. When some medicines cannot dissolve in water and form precipitates in the medicated solution, ordinary solutions cannot prevent these medicines from precipitating, resulting in a large difference in the concentration of medicines in different parts of the container.

[0005] Later, although a wearable portable burn rinsing and soaking device appeared, such as the one disclosed in patent application number CN201921328428.3, this soaking device consists of a cylindrical elastic body; elastic sealing rings at both ends of the elastic body; an inflation and deflation structure on the elastic body to inflate or deflate it; and a cleaning structure to deliver or discharge cleaning liquid within the elastic body. While the delivery and discharge of the liquid allows for the introduction of a hotter liquid after the initial cooling and new, unprecipitated liquid after sedimentation, in actual use, the flow rate of the liquid in contact with the wound can be too fast, rinsing the wound and causing pain. Furthermore, during soaking, residual tissue or scabs may fall off, and if not removed promptly, these can easily breed bacteria, increasing the risk of secondary infection. Summary of the Invention

[0006] The present invention aims to provide a burn medicated bath device to reduce the scouring of the wound by water flow, thereby reducing the pain of the wound during the medicated bath; at the same time, it removes sloughed tissue during the medicated bath, reducing the risk of secondary infection.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a burn medicated bath device, comprising a soaking tub, the soaking tub including an inner tub and an outer tub, the inner tub being located inside the outer tub, and the top of the inner tub being lower than the top of the outer tub, the outer diameter of the inner tub being smaller than the inner diameter of the outer tub, forming a heat-insulating space between the inner tub and the outer tub; the bottom of the inner tub is provided with several drain holes, the drain holes being connected to drain pipes; the drain pipes are connected to a filtration and disinfection unit, the filtration and disinfection unit including a filter box and a heating box, the filter box being provided with a filter screen, the side wall of the filter box being provided with an inlet and an outlet, the inlet and outlet being located on opposite sides of the filter screen, the drain pipe being connected to the inlet; the outlet being connected to the heating box, the heating box being provided with a heating element; the heating box being connected to an air inlet and an exhaust pipe, the exhaust pipe being connected to the heat-insulating space.

[0008] The beneficial effects of this plan are:

[0009] 1. The heating element in this solution can heat the medicinal liquid, and then the heated medicinal liquid is introduced into the heat preservation space. Since the heat preservation space is located outside the inner barrel, the heat in the heated medicinal liquid in the heat preservation space can be transferred to the inner barrel, thus slowing down the cooling rate of the medicinal liquid in the inner barrel.

[0010] 2. Because the top of the inner tub is lower than the outer tub, when more medication is introduced into the insulated space, the medication will slowly flow from the top of the inner tub along its side wall, raising the temperature of the medication within. Compared to pouring the medication directly into the inner tub, allowing it to flow downwards along the side wall results in a lower flow rate, thus avoiding irritation to the wound and causing pain. Furthermore, the downward-flowing medication adheres to the side wall, further distancing itself from the patient and minimizing irritation to the wound. Secondly, the side wall of the inner tub guides the added medication, promoting its downward flow and raising the temperature in the middle and lower parts of the inner tub.

[0011] 3. During the soaking process, the detached tissue settles at the bottom of the inner tank. In this solution, the settled tissue is discharged simultaneously when the medicine in the inner tank is drained through the drain hole. The medicine is also filtered when it is passed through the filter screen to separate the tissue from the medicine. This prevents the tissue from re-entering the inner tank when the medicine is heated and added back into the inner tank, thus avoiding bacterial growth and reducing the risk of secondary infection.

[0012] 4. When a longer medicated bath is required, the heating element can heat the medicinal solution in the heating chamber to a higher temperature. This higher temperature has a sterilizing effect on the solution, further reducing the risk of secondary infection. Secondly, when the medicinal solution is at a high temperature, sterilized gas is introduced into the heating chamber through the air inlet. The hotter medicinal solution inside the chamber heats the gas, creating warm air. This warm air is then introduced into the heating space to keep the medicinal solution warm. As the heated gas dissipates into the inner tub, the patient remains in a warm environment, further preventing exposed body parts from getting cold during the bath. Furthermore, the gas entering the heating chamber quickly cools the hot medicinal solution to a suitable temperature, making it easy to re-infuse the solution into the insulated space and inner tub for reuse.

[0013] Furthermore, the connection between the exhaust pipe and the insulation space is located at the bottom of the outer casing.

[0014] The beneficial effects of this solution are as follows: the gas entering the heat preservation space through the exhaust pipe forms bubbles in the liquid medicine in the heat preservation space and rises. During this process, the bubbles can stir the liquid medicine in the heat preservation space, promote the mixing of drugs that are easy to precipitate with the liquid medicine, and improve the uniformity of drugs in the liquid medicine in various parts.

[0015] Furthermore, the top of the outer tub is detachably connected to a top cover, which has an opening for the patient's body to protrude.

[0016] The beneficial effect of this solution is that the top cover can slow down the rate of heat loss from the liquid medicine, thereby reducing the cooling rate of the liquid medicine.

[0017] Furthermore, an annular pipe is provided at the bottom of the insulated space, which is connected to the exhaust pipe, and several air holes are provided on the annular pipe along its length.

[0018] The beneficial effects of this scheme are: the gas can be introduced into the bottom of the insulation space more evenly through the ring pipe and several air holes, thereby agitating the liquid medicine in all parts of the insulation space.

[0019] Furthermore, the pores are located at the bottom of the annular tube.

[0020] The beneficial effects of this solution are as follows: When drugs in the heat-insulating space precipitate, they will settle at the bottom of the heat-insulating space. In this solution, the gas is discharged from the vent and directly stirs the liquid around the precipitated drugs, thus improving the effect of preventing drug precipitation.

[0021] Furthermore, a limiting block is provided at the bottom of the insulation space, and a strip groove extending vertically is provided on the limiting block. The annular tube passes through the strip groove and slides in cooperation with the strip groove.

[0022] The beneficial effects of this scheme are as follows: when the gas is discharged from the vent, it forms a downward airflow. The annular tube will move upward under the action of the reaction force. When the airflow decreases, it will return to its original position under the action of gravity. Therefore, the annular tube in this scheme will vibrate at the bottom of the heat preservation space, thereby agitating the surrounding liquid medicine and improving the effect of preventing drug precipitation.

[0023] Furthermore, the top of the insulated space is provided with a sealing plate for sealing the insulated space; the top of the sealing plate is provided with a lower push rod, which penetrates the top cover vertically and is threaded into the top cover; the insulated space is connected to a second air pipe, which is connected to a drain hole.

[0024] The beneficial effects of this solution are as follows: After the insulation space is sealed by the sealing plate, the liquid and gas in the insulation space will not be able to enter the inner bucket from the top. Therefore, when heating is introduced into the insulation space, the heating will gather below the sealing plate and finally enter the inner bucket from the bottom through the second air pipe and the drain hole. On the one hand, this can help the sediment stuck in the drain hole to come out, and on the other hand, it can directly promote the flow of the medicine in the inner bucket, thereby improving the mixing efficiency of the medicine and the sediment in the inner bucket. This solution is suitable for patients whose wounds no longer cause pain due to slight water flow.

[0025] Furthermore, an annular outer baffle is fixed to the inner wall of the outer tub, and an annular inner baffle is fixed to the outer wall of the inner tub. The tops of the outer baffle and the inner baffle are at the same height and can simultaneously abut against the bottom of the sealing plate.

[0026] The beneficial effects of this solution are as follows: the sealing plate can quickly seal the insulated space by abutting against the inner and outer baffles, and the contact area between the inner and outer baffles and the sealing plate is larger, resulting in a better sealing effect. When it is necessary to add the medicine from the insulated space to the inner bucket, the medicine and medicine in the inner bucket must pass over the inner baffle to enter the inner bucket from the top. When there are still tissues or relatively large Chinese medicinal materials remaining in the medicine, the larger objects are more difficult to pass over the inner baffle because they are blocked. Therefore, this solution can also prevent residual tissues and Chinese medicinal materials from entering the inner bucket, avoid the growth of bacteria from residual tissues causing secondary infection, and prevent large pieces of Chinese medicinal materials from entering the inner bucket and scraping against the wound, causing pain or secondary damage to the wound.

[0027] Furthermore, the exhaust pipe includes a first pipe body and a second pipe body. The first pipe body connects the heating box to the water outlet, and the second pipe body connects the cavity of the filter box near the water inlet to the insulation space.

[0028] The beneficial effects of this solution are as follows: the gas first passes through the filter box before entering the insulated space. The direction of the gas passing through the filter holes is opposite to the flow direction of the medicine liquid discharged from the inner tank when the filter screen filters it. The gas can dislodge any medicine or tissue stuck in the filter holes, thus restoring the filtering effect of the filter screen. Secondly, when the use is finished or the temperature of the medicine in the insulated space is low, the filter box and filter screen can be heated by a relatively warmer heater to prevent bacterial growth and further reduce the risk of secondary infection.

[0029] Furthermore, the filter screen is detachably connected to the filter box, and the filter box is equipped with a closable cleaning port.

[0030] The benefits of this solution are: after filtration is complete, the filter screen can be removed from the cleaning port for timely cleaning, further preventing the growth of bacteria. Attached Figure Description

[0039] Example

[0040] The implementation examples are basically as follows Figures 1 to 6 As shown, a burn medicated bath device includes a soaking tub and a filtration and disinfection unit. In actual implementation, the shape and size of the inner tub 5 and the outer tub 2 are determined according to the area to be medicated: the inner tub 5 of the soaking tub used for leg medicated baths can be circular, and its height is lower than that of the soaking tub used for whole-body medicated baths. This embodiment uses the soaking tub used for whole-body medicated baths as an example for illustration:

[0041] The soaking tub includes an inner tub 5 and an outer tub 2. Specifically, the side walls of the inner tub 5 and the outer tub 2 are detachably connected to the base 1, and the inner tub 5 and the outer tub 2 share a base 1. The inner tub 5 is located inside the outer tub 2, and the bottom of the side walls of the inner tub 5 and the outer tub 2 are attached to the base 1 and fixed with bolts. A sealing ring is snapped into the bottom of the side wall to seal between the side wall and the base 1.

[0042] The inner tub 5 has a protrusion 11 on its inner side for the patient to maintain a sitting position. The side wall of the protrusion 11 is an inclined surface 12. Both the inclined surface 12 and the base 1 have several drainage holes 13. The base 1 has an inner cavity, and the drainage holes 13 communicate with the inner cavity. The inner cavity is connected to a drain pipe 52 via a three-way valve. The filtration and disinfection unit includes a filter box 7 and a heating box 9. A filter screen 8 is vertically installed inside the filter box 7. A support block is welded to the inner wall of the filter box 7. The filter screen 8 is snapped into the filter box 7 and abuts against the support block. The top of the filter box 7 has a cleaning port for removing the filter screen 8, and a cleaning port cover is threaded onto the top of the filter box 7 to seal the cleaning port. The upper and lower parts of the filter box 7 have water inlets and outlets, respectively. The end of the drain pipe 52 away from the inner tub 5 is connected to the water inlet.

[0043] The top of the heating chamber 9 is equipped with a liquid inlet and a liquid inlet cover. The liquid inlet cover is threaded into the liquid inlet to seal it. The heating chamber 9 contains a heating element; specifically, in this embodiment, the heating element is a conventional heating rod with a temperature control module. The water outlet is connected to the top of the heating chamber 9 via a three-way valve. The bottom of the heating chamber 9 is also connected to an air inlet; in this embodiment, the air inlet is an air pump, which pumps clean gas into the heating chamber 9.

[0044] The top of the inner tub 5 is lower than that of the outer tub 2. The length and width of the outer side wall of the inner tub 5 are smaller than those of the inner side wall of the outer tub 2, respectively, forming an annular insulation space 23 between the inner tub 5 and the outer tub 2. An annular inner baffle 51 is integrally formed on the top of the inner tub 5, and an annular outer baffle 22 is integrally formed on the inner wall of the outer tub 2. The tops of the outer baffle 22 and the inner baffle 51 are at the same height, and a gap is maintained between the outer baffle 22 and the inner baffle 51 for the medicine to pass through. An annular sealing plate 4 is provided at the top of the insulation space 23. The sealing plate 4 is located above the inner baffle 51 and the outer baffle 22, and a lower push rod 41 is ball-jointed to the top of the sealing plate 4. A top cover 3 is snapped onto the top of the outer tub 2. The top cover 3 is detachably connected to the outer tub 2 by bolts, and the lower push rod 41 penetrates vertically through the top cover 3 and is threaded into the top cover 3. The top cover 3 has an opening 31 facing the protrusion 11, allowing the patient's head, neck and other body parts that do not require medicated bath to protrude.

[0045] The insulated space 23 is connected to a second air pipe 21. The connection position of the second air pipe 21 to the outer barrel 2 is lower than the outer baffle 22. The end of the second air pipe 21 away from the outer barrel 2 is connected to the inner cavity through a three-way valve for introducing warm air into the inner cavity.

[0046] The bottom of the insulation space 23 is provided with an annular tube 6, and multiple limiting blocks 14 are provided along the length of the annular tube 6 inside the insulation space 23. The limiting blocks 14 are provided with vertically oriented strip grooves 15, and the annular tube 6 passes through the strip grooves 15 and can slide up and down along the strip grooves 15. The bottom of the annular tube 6 is provided with several air holes along its length. The annular tube 6 is connected to an exhaust pipe and a return pipe through a three-way valve. The end of the return pipe away from the annular tube 6 is connected to the bottom of the heating box 9. In this embodiment, the exhaust pipe includes a first pipe body 61 and a second pipe body 62. One end of the first pipe body 61 is connected to the top of the heating box 9 through a valve, and the other end is connected to the water outlet through a three-way valve. One end of the second pipe body 62 is connected to the upper part of the filter box 7, and the other end is connected to the annular pipe 6, so that the warm air generated in the heating box 9 can pass through the filter box 7 and the return pipe in sequence, and then enter the heat preservation space 23 through the air hole on the return pipe. In actual implementation, the top of the heating box 9 can also be directly connected to the annular pipe 6 through a pipe, and a valve can be set on the pipe. Opening the valve can directly introduce the warm air into the heat preservation space 23; or only the first pipe body 61 is set between the water outlet and the heating box 9. The filtered medicine in the filter box 7 is introduced into the heating box 9 through the first pipe body 61, and the warm air is guided into the filter box 7, so that the warm air can dry the medicine remaining in the pipe and disinfect the inside of the pipe.

[0047] The specific implementation process is as follows:

[0048] Initially, the outer tub 2 and inner tub 5 are installed after the patient sits on the protrusion 11. When the patient's wound no longer experiences pain due to the water flow, the medication is added directly to the inner tub 5 from above. If the wound is still healing and prone to pain, the medication is first added to the heating chamber 9, and then air is introduced into the heating chamber 9 through the air inlet to increase the pressure inside. Then, the valve between the return pipe and the ring pipe 6 is opened, allowing the medication to enter the insulation space 23 through the return pipe and the ring pipe 6. When the liquid level in the insulation space 23 is higher than the top of the inner tub 5, the medication is gradually introduced into the inner tub 5 from the top, reducing irritation to the patient's wound. After all the medication in the heating chamber 9 has entered the insulation space 23, the valve between the return pipe and the ring pipe 6 is closed, and new medication is added to the heating chamber, repeating the above steps until the medication in the inner tub 5 covers the wound.

[0049] During the soaking process, the top cover 3 is installed to slow down the rate of heat loss from the medicinal solution, thereby reducing the cooling rate of the solution. When the temperature of the medicinal solution decreases, the valves between the inner cavity and the filter box 7, and between the filter box 7 and the heating box 9, are opened. The medicinal solution at the bottom of the inner barrel 5, carrying precipitated drugs and sloughed tissue, enters the filter box 7 and is filtered by the filter screen 8. The filtered medicinal solution enters the heating box 9, and the heating element is activated to heat the medicinal solution. After reaching the preset temperature, the heating element stops working. Repeating the above steps allows the heated medicinal solution to be introduced into the heat preservation space 23, promoting the mixing of drugs and liquid in the solution. At the same time, the heated medicinal solution enters the inner barrel 5 from the top, raising the temperature of the medicinal solution in the inner barrel 5.

[0050] When the ambient temperature is low, a certain amount of medicine is retained in the heating chamber 9. Then, the preset temperature of the heating element is increased to heat the medicine to a higher temperature. At the same time, the air intake is activated to introduce sterilized gas into the heating chamber 9. After entering the heating chamber 9, the gas is heated by the medicine to form warm air. Then, the valve on the exhaust pipe is opened to allow the warm air to enter the insulation space 23 through the annular pipe 6, maintaining the temperature of the medicine in the insulation space 23, thereby indirectly slowing down the cooling rate of the medicine in the inner barrel 5. Meanwhile, because the density of gas is less than that of liquid, the warm air in the insulation space 23 rises along the medicine and finally flows to the upper space of the inner barrel 5 and the outer barrel 2, so that the part of the patient's body above the medicine is also surrounded by warm air, preventing the patient from catching a cold due to hypothermia.

[0051] When using Chinese medicinal materials that require prolonged high-temperature soaking to fully exert their medicinal effects, the medicinal materials are directly added to the heating chamber 9. By increasing the preset temperature of the heating element, the medicinal liquid in the heating chamber 9 is kept at a relatively higher temperature, which fully extracts the effective substances in the Chinese medicinal materials. The medicinal liquid is then added to the inner barrel 5 through the above steps.

[0052] When the patient's wound is pain-free, the sealing plate 4 can be pressed against the outer baffle 22 and inner baffle 51 using the lower push rod 41 to seal the heat-insulating space 23. Then, the valve on the second air pipe 21 can be opened to allow warm air to enter the inner cavity through the second air pipe 21. The warm air enters the inner tank 5 directly through the drain hole 13, improving the mixing efficiency of the medicine and the liquid in the inner tank 5 while preventing the drain hole 13 from being blocked. During prolonged soaking, the temperature inside the hot water tank can also be increased to sterilize the medicine in the hot water tank. When it is necessary to use a medicine with a relatively higher temperature in the hot water tank to increase the water temperature in the inner tank 5, the air intake device should be activated first to quickly lower the temperature of the medicine to a usable level by venting air into the hot water tank. During this process, if the temperature of the generated warm air is too high, the liquid inlet should be opened to release the excessively hot warm air generated earlier to the outside.

[0053] Throughout the soaking process, the heating air in this system, after being drawn from the heating box 9, does not directly enter the inner tank 5 for use. Instead, it is cooled by the medicinal liquid in the insulation space 23 before entering the space above the inner tank 5 or entering the medicinal liquid in the inner tank 5 through the second air pipe 21. Therefore, when the heating air is close to the patient, the temperature has already been reduced to a suitable level, preventing secondary burns. In actual implementation, temperature sensors can also be installed on the second air pipe 21 and the second pipe body 62 to detect the temperature of the heating air. When the temperature of the heating air is too high, closing the valves on the second air pipe 21 and the second pipe body 62 or opening the liquid inlet can prevent the high-temperature heating air from approaching the patient, ensuring high safety in use.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solutions of the present invention, and these should also be considered within the scope of protection of the present invention.
