Description

Technical Field

[0001] The invention relates to the field of medical auxiliary equipment, and in particular to a burn medicinal bath device. Background Art

[0002] Burns are tissue damage caused by high temperature, chemicals, shock, etc. The degree of burns can be divided into four degrees according to local changes: the first degree, congestion due to vascular paralysis; the second degree, the formation of burn blisters filled with serum; the third degree, tissue necrosis; the fourth degree, tissue carbonization. After a burn, the skin, which serves as the body's natural shield against microbial invasion, is destroyed, and the necrotic skin tissue is a good "culture medium" for the growth and reproduction of microorganisms. Therefore, the burn wound is very susceptible to infection. Therefore, burn patients also need to pay attention to cleaning and disinfecting the skin during treatment.

[0003] The traditional cleaning and disinfection method is to wipe the affected area with medical cotton balls dipped in disinfectant or directly pour disinfectant on the affected area for cleaning. However, when the burn area is large, the above operation takes too long; and when the affected area has not yet completely scabbed and is still painful, direct contact with materials such as medical cotton balls will undoubtedly increase the patient's pain. Current studies have shown that medicated bathing is one of the important means to promote healing and prevent infection for patients with wound infection, wound secretions that cannot be cleared by conventional dressing changes, residual wounds in the late stage of burns, before wound skin grafting, and functional exercises after wound healing. At the same time, medicated bathing can also allow the drug to quickly cover all wounds, thereby relieving pain and reducing scar formation.

[0004] When taking a medicinal bath, a container is needed to dissolve the medicine in water to form a medicinal solution, and then the affected area is immersed in the medicinal solution. However, ordinary containers cannot keep the medicinal solution at a suitable temperature for a long time. When some drugs are insoluble in water and form precipitates in the medicinal solution, ordinary solutions cannot avoid the precipitation of these drugs, resulting in large differences in drug concentrations in different parts of the container.

[0005] Although a wearable portable burn irrigation and soaking device disclosed in the patent application number CN201921328428.3 has appeared, this soaking device is provided by setting a cylindrical elastic body; elastic sealing rings are provided at both ends of the elastic body; an inflation and exhaust structure is provided on the elastic body, and the elastic body is inflated or exhausted by the inflation and exhaust structure to expand or contract the elastic body; a cleaning structure is provided on the elastic body, and the cleaning liquid is transported or discharged from the elastic body by the cleaning structure. Although the method of transporting and discharging the liquid medicine can allow the temperature of the liquid medicine to be lowered and a new unprecipitated liquid medicine to be introduced after the drug is precipitated, in actual use, the flow rate of the liquid medicine in contact with the wound surface is too fast, thereby flushing the wound surface and causing pain on the wound surface; and during the soaking process, the residual tissue or scab on the wound surface may fall off, and if the shed tissue is not removed in time, it is easy to breed bacteria, increasing the risk of secondary infection. Summary of the invention

[0006] The present invention is intended to provide a burn medicinal bath device to reduce the scouring of the wound surface by water flow, thereby reducing the pain of the wound surface during the medicinal bath; at the same time, the detached tissue is removed during the medicinal bath to reduce the risk of secondary infection.

[0007] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a burn medicinal bath device, including a soaking barrel, the soaking barrel includes an inner barrel and an outer barrel, the inner barrel is arranged on the inner side of the outer barrel, and the top of the inner barrel is lower than the top of the outer barrel, the outer diameter of the inner barrel is smaller than the inner diameter of the outer barrel, and a heat preservation space is formed between the inner barrel and the outer barrel; a plurality of drainage holes are arranged at the bottom of the inner barrel, and the drainage holes are connected with drainage pipes; the drainage pipe is connected with a filtering and disinfecting unit, and the filtering and disinfecting unit includes a filtering box and a heating box, a filter screen is arranged in the filtering box, and a water inlet and a water outlet are arranged on the side wall of the filtering box, and the water inlet and the water outlet are respectively located on both sides of the filter screen, and the drainage pipe is connected with the water inlet; the water outlet is connected with the heating box, and a heating element is arranged in the heating box; the heating box is connected with an air inlet and an exhaust pipe, and the exhaust pipe is connected with the heat preservation space.

[0008] The beneficial effects of this program are:

[0009] 1. The heating element in this scheme can heat the medicine liquid, and then pass the heated medicine liquid into the insulation space. Since the insulation space is located outside the inner barrel, the heat in the medicine liquid with increased temperature in the insulation space can be transferred to the inner barrel, slowing down the cooling rate of the medicine liquid in the inner barrel.

[0010] 2. Since the top of the inner barrel is lower than the outer barrel, after more liquid medicine is introduced into the heat preservation space, the liquid medicine will slowly flow into the inner barrel from the top of the inner barrel along the side wall of the inner barrel, increasing the temperature of the liquid medicine in the inner barrel. Compared with directly pouring the liquid medicine into the inner barrel, letting the liquid medicine flow down along the side wall of the inner barrel can make the flow rate of the liquid medicine in the inner barrel lower, thereby avoiding scouring the wound surface and causing pain. In addition, the liquid medicine flowing down is close to the side wall of the inner barrel, further away from the patient, and further avoiding scouring the wound surface. Secondly, the side wall of the inner barrel can guide the added liquid medicine, prompting the liquid medicine to flow further downward along the side wall of the inner barrel, thereby increasing the temperature of the middle and lower parts of the inner barrel.

[0011] 3. During the soaking process, the tissue that falls off is deposited at the bottom of the inner barrel. In this solution, when the medicine liquid in the inner barrel is discharged through the drainage hole, the deposited tissue can be discharged at the same time, and the medicine liquid is filtered when passing through the filter to separate the tissue from the medicine liquid. In this way, when the medicine liquid is heated and re-added to the inner barrel, the tissue is prevented from re-entering the inner barrel, thereby avoiding the growth of bacteria and reducing the risk of secondary infection.

[0012] 4. When a longer medicinal bath is required, the medicinal liquid in the heating box can be heated to a higher temperature through the heating element, and the higher temperature can have a sterilizing effect on the medicinal liquid, thereby further reducing the risk of secondary infection. Secondly, when the temperature of the medicinal liquid is high, when the sterilized gas is introduced into the heating box through the air inlet, the medicinal liquid with a higher temperature in the heating box can heat the gas to form warm air, and the warm air is passed into the heating space to first insulate and heat the medicinal liquid in the heating space, and when the heated gas escapes into the inner barrel, the patient can be in a warm environment, further avoiding the body parts exposed by the medicinal bath from getting cold. Secondly, after the gas enters the heating box, the temperature of the medicinal liquid with a higher temperature in the heating box can be quickly reduced to a suitable temperature, thereby facilitating the re-introduction of the medicinal liquid into the insulation space and the inner barrel for reuse.

[0013] Furthermore, the position where the exhaust pipe is connected to the heat preservation space is located at the lower part of the outer barrel.

[0014] The beneficial effect of this scheme is that the gas entering the insulation space through the exhaust pipe forms bubbles in the medicine liquid in the insulation space and rises. In this process, the bubbles can stir the medicine liquid in the insulation space, promote the mixing of medicines that are easy to precipitate in the medicine liquid with the medicine liquid, and improve the uniformity of medicines in the medicine liquid in various parts.

[0015] Furthermore, a top cover is detachably connected to the top of the outer barrel, and an opening is provided on the top cover for allowing the patient's body to protrude.

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

[0017] Furthermore, an annular tube is provided at the bottom of the heat preservation space, the annular tube is connected with the exhaust pipe, and a plurality of air holes are provided on the annular tube in the extension direction.

[0018] The beneficial effect of this solution is that the gas can be more evenly introduced into the bottom of the heat preservation space through the annular tube and the plurality of air holes, thereby stirring the medicine liquid in various places of the heat preservation space.

[0019] Further, the air hole is located at the bottom of the annular tube.

[0020] The beneficial effect of this solution is that when the medicine in the heat preservation space precipitates, it will settle at the bottom of the heat preservation space. In this solution, the gas is discharged from the pores to directly stir the liquid medicine around the precipitated medicine, so the effect of preventing the medicine from settling is better.

[0021] Furthermore, a limit block is provided at the bottom of the heat preservation space, and a strip groove extending in the vertical direction is provided on the limit block, and the annular tube passes through the strip groove and is slidably matched with the strip groove.

[0022] The beneficial effect of this scheme is that when the gas is discharged from the pores, a downward airflow is formed, and the annular tube will move upward under the action of the reaction force. When the airflow decreases, it will return to its original position downward under the action of gravity. Therefore, the annular tube in this scheme will vibrate at the bottom of the insulation space, thereby stirring the surrounding medicine liquid, which is more effective in preventing the medicine from settling.

[0023] Furthermore, a sealing plate for sealing the insulation space is provided on the top of the insulation space; a lower push rod is provided on the top of the sealing plate, the lower push rod vertically penetrates the top cover and cooperates with the top cover thread; the insulation space is connected to a second air pipe, and the second air pipe is connected to the drainage hole.

[0024] The beneficial effect of this solution is that after the heat preservation space is sealed by the sealing plate, the liquid and gas in the heat preservation space will not be able to enter the inner barrel from the top of the inner barrel. Therefore, when warm air is introduced into the heat preservation space, the warm air gathers under the sealing plate and finally enters the inner barrel from the bottom of the inner barrel through the second air pipe and the drainage hole. On the one hand, it can promote the sediment stuck in the drainage hole to escape, and on the other hand, it can also directly promote the flow of the medicine liquid in the inner barrel, thereby improving the mixing efficiency of the medicine liquid and the precipitated medicine in the inner barrel. It is suitable for patients whose wound surface is no longer painful due to slight water flow.

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

[0026] The beneficial effects of this solution are as follows: the sealing plate can quickly seal the heat preservation space by abutting against the inner baffle and the outer baffle, and the contact area between the inner baffle and the outer baffle and the sealing plate is larger, and the sealing effect is better. When the liquid medicine in the heat preservation space needs to be added to the inner barrel, the medicine and liquid medicine in the inner barrel need to pass over the inner baffle to enter the inner barrel from the top of the inner barrel. When there are still tissues or relatively larger Chinese medicinal materials in the liquid medicine, it is more difficult for larger objects to pass over the inner baffle because they are blocked by the inner baffle. Therefore, this solution can also prevent residual tissues and Chinese medicinal materials from entering the inner barrel, prevent residual tissues from breeding bacteria and causing secondary infection, and prevent large pieces of Chinese medicinal materials from entering the inner barrel and rubbing against the wound surface to cause pain or secondary damage to the wound surface.

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

[0028] The beneficial effects of this solution are: the gas first passes through the filter box and then enters the heat preservation space. The direction of the gas passing through the filter holes is opposite to the flow direction of the liquid medicine discharged from the inner barrel when the filter screen filters the liquid medicine. The gas can cause the medicine or tissue stuck in the filter holes to fall off, so that the filter screen can restore the filtering effect. Secondly, when the use is over or the temperature of the medicine in the heat preservation space is low, the filter box and filter screen can be heated by relatively higher temperature heating to prevent bacteria from growing and further reduce the risk of secondary infection.

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

[0030] The beneficial effect of this solution is that after the filtration is completed, the filter screen can be removed and taken out from the cleaning port, and the filter screen can be cleaned in time to further avoid the breeding of bacteria. BRIEF DESCRIPTION OF THE DRAWINGS

In actual implementation, the shapes and sizes of the inner barrel 5 and the outer barrel 2 are determined according to the part to be bathed: the inner barrel 5 of the soaking barrel for bathing the legs can be round and lower in height than the soaking barrel for soaking the whole body. This embodiment is described by taking the soaking barrel for soaking the whole body as an example:

[0041] The soaking barrel includes an inner barrel 5 and an outer barrel 2. Specifically, the side walls and base 1 of the inner barrel 5 and the outer barrel 2 of the present invention are detachably connected, and the inner barrel 5 and the outer barrel 2 share a base 1. The inner barrel 5 is located on the inner side of the outer barrel 2, and the bottoms of the side walls of the inner barrel 5 and the outer barrel 2 are both in contact with the base 1 and fixed by bolts. A sealing ring is clamped at the bottom of the side wall for sealing between the side wall and the base 1.

[0042] A boss 11 is provided on the inner side of the inner barrel 5 for the patient to maintain a sitting position. The side wall of the boss 11 is an inclined surface 12. A plurality of drainage holes 13 are provided on the inclined surface 12 and the base 1. An inner cavity is provided in the base 1. The drainage holes 13 are connected to the inner cavity. The inner cavity is connected to a drainage pipe 52 through 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 provided in the filter box 7. A support block is welded to the inner wall of the filter box 7. The filter screen 8 is engaged with the filter box 7 and abuts against the support block. A cleaning port is provided at the top of the filter box 7 for taking out the filter screen 8. A cleaning port cover is threadedly connected to the top of the filter box 7 to close the cleaning port. A water inlet and a water outlet are provided at the upper and lower parts of the filter box 7, respectively. The end of the drainage pipe 52 away from the inner barrel 5 is connected to the water inlet.

[0043] The top of the heating box 9 is provided with a liquid filling port and a liquid filling port cover, and the liquid filling port cover is matched with the liquid filling port thread to close the liquid filling port. A heating element is provided in the heating box 9. Specifically, the heating element in this embodiment adopts an existing heating rod with a temperature control module, and the water outlet is connected to the top of the heating box 9 through a three-way valve. The bottom of the heating box 9 is also connected to an air inlet. The air inlet in this embodiment adopts an air pump, and clean gas can be pumped into the heating box 9 through the air pump.

[0044] The top of the inner barrel 5 is lower than the outer barrel 2, and the length and width of the outer wall of the inner barrel 5 are respectively smaller than the length and width of the inner wall of the outer barrel 2, so that an annular heat preservation space 23 is formed between the inner barrel 5 and the outer barrel 2. The top of the inner barrel 5 is integrally formed with an annular inner baffle 51, and the inner wall of the outer barrel 2 is integrally formed with an annular outer baffle 22. The tops of the outer baffle 22 and the inner baffle 51 are of the same height, and a gap for the passage of the liquid medicine is reserved between the outer baffle 22 and the inner baffle 51. The upper part of the heat preservation space 23 is provided with an annular sealing plate 4, which is located above the inner baffle 51 and the outer baffle 22, and the top of the sealing plate 4 is ball-hinged with a lower push rod 41. The top of the outer barrel 2 is clamped with a top cover 3, and the top cover 3 is detachably connected to the outer barrel 2 by bolts at the same time. The lower push rod 41 vertically penetrates the top cover 3 and is threadedly matched with the top cover 3. The top cover 3 is provided with an opening 31 facing the boss 11, through which the patient's head, neck and other body parts that do not need to be bathed in medicine can be exposed.

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

[0046] An annular tube 6 is provided at the bottom of the heat preservation space 23, and a plurality of stoppers 14 are provided in the heat preservation space 23 along the length direction of the annular tube 6. A strip groove 15 is vertically provided on the stoppers 14. The annular tube 6 passes through the strip groove 15 and can slide up and down along the strip groove 15. A plurality of air holes are provided at the bottom of the annular tube 6 along the length direction. 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. The exhaust pipe in this embodiment includes a first tube body 61 and a second tube body 62. One end of the first tube 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 tube 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 formed in the heating box 9 can pass through the filter box 7 and the return pipe in sequence, and then enter the insulation space 23 from the air holes 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 pipeline, and a valve is set on the pipeline. The warm air can be directly passed into the insulation space 23 by opening the valve; or only the first tube body 61 is set between the water outlet and the heating box 9, and the filtered liquid medicine in the filter box 7 is introduced into the heating box 9 through the first tube body 61, and the warm air is guided into the filter box 7, so that the warm air can dry the residual liquid medicine in the pipeline and disinfect the inside of the pipeline.

[0047] The specific implementation process is as follows:

[0048] Initially, the outer barrel 2 and the inner barrel 5 are installed after the patient sits on the boss 11. When the patient's wound surface no longer causes pain due to the flushing of the water flow, the liquid medicine is directly added to the inner barrel 5 from above. When the patient's wound surface has not yet healed and is still prone to pain, the liquid medicine is first added to the heating box 9, and then the heating box 9 is ventilated through the air inlet to increase the pressure in the heating box 9. Then, the valve between the return pipe and the annular pipe 6 is opened to allow the liquid medicine to enter the heat preservation space 23 through the return pipe and the annular pipe 6. Then, when the liquid level in the heat preservation space 23 is higher than the top of the inner barrel 5, the liquid medicine gradually and slowly enters the inner barrel 5 from the top of the inner barrel 5 to reduce the stimulation to the patient's wound surface. When all the liquid medicine in the heating box 9 enters the heat preservation space 23, the valve between the return pipe and the annular pipe 6 is closed, and then new liquid medicine is added to the heating element and the above steps are repeated until the liquid medicine in the inner barrel 5 covers the wound surface.

[0049] During the soaking process, the top cover 3 is installed to slow down the speed of heat dissipation in the medicine liquid, thereby reducing the speed of cooling the medicine liquid. When the temperature of the medicine liquid 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, and the medicine liquid at the bottom of the inner barrel 5 enters the filter box 7 with the precipitated medicine and detached tissue and is filtered by the filter 8. The filtered medicine liquid enters the heating box 9, and the heating element is started to heat the medicine liquid. After reaching the preset temperature, the heating element stops working, and the above steps are repeated to pass the medicine liquid with increased temperature into the heat preservation space 23, so that the medicine in the medicine liquid is mixed with the liquid, and at the same time, the medicine liquid with increased temperature enters the inner barrel 5 from the top of the inner barrel 5, thereby increasing the temperature of the medicine liquid in the inner barrel 5.

[0050] When the ambient temperature is low, a certain amount of liquid medicine is retained in the heating box 9, and then the preset temperature of the heating element is increased to heat the liquid medicine to a higher temperature. At the same time, the air inlet is started to introduce sterilized gas into the heating box 9 through the air inlet. After the gas enters the heating box 9, it is heated by the liquid 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 from the annular pipe 6 first, and maintain the temperature of the liquid medicine in the insulation space 23, thereby indirectly slowing down the cooling rate of the liquid medicine in the inner barrel 5; at the same time, because the density of the gas is less than that of the liquid, the warm air in the insulation space 23 rises along the liquid medicine, and finally flows to the upper space of the inner barrel 5 and the outer barrel 2, so that the patient's body parts above the liquid medicine are also in an environment surrounded by warm air, thereby preventing the patient from catching a cold due to low body temperature.

[0051] When using Chinese medicinal materials that require long-term high-temperature immersion to fully exert their medicinal effects, the Chinese medicinal materials are directly added to the heating box 9. By increasing the preset temperature of the heating element, the medicinal liquid in the heating box 9 is kept at a relatively higher temperature to fully extract the effective substances in the Chinese medicinal materials, and the medicinal liquid is continued to be added to the inner barrel 5 through the above steps.

[0052] When the patient does not feel pain on the wound, the sealing plate 4 can be pressed against the outer baffle 22 and the inner baffle 51 by the lower push rod 41 to seal the heat preservation space 23, and then the valve on the second air pipe 21 can be opened to pass the warm air into the inner cavity through the second air pipe 21. The warm air directly enters the inner barrel 5 through the drainage hole 13, which improves the mixing efficiency of the liquid medicine and the medicine in the inner barrel 5 and prevents the drainage hole 13 from being blocked. When soaking for a long time, the temperature in the hot water tank can also be increased to sterilize the liquid medicine in the hot water tank. When it is necessary to use the relatively higher temperature liquid medicine in the hot water tank to increase the water temperature in the inner barrel 5, the air intake part is first started to quickly reduce the temperature of the liquid medicine to a usable level by ventilating the hot water tank. In this process, if the temperature of the generated warm air is too high, the liquid filling port is opened to discharge the excessively high temperature warm air generated in the early stage to the outside.

[0053] During the entire soaking process, the warm air in this scheme will not directly enter the inner barrel 5 for use after being guided out from the heating box 9, but will be cooled by the liquid medicine in the heat preservation space 23 before entering the space above the inner barrel 5 or entering the liquid medicine in the inner barrel 5 through the second air pipe 21. Therefore, when the warm air approaches the patient, the temperature has been reduced to an appropriate level, and secondary burns will not occur. In actual implementation, a temperature sensor can also be provided on the second air pipe 21 and the second tube body 62 to detect the temperature of the warm air. When the warm air temperature is too high, closing the valves on the second air pipe 21 and the second tube body 62 or opening the liquid filling port can prevent the high-temperature warm air from approaching the patient, and the use is highly safe.

[0054] The above is only an embodiment of the present invention, and the common knowledge such as the known specific technical solutions and / or characteristics in the solution is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the present invention, several modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
