The traditional dipping therapy is to set a special dipping treatment room, when a patient needs to be immersed, the patient can not conveniently use the dipping equipment of the special treatment room because the burn patient generally has serious illness state and even can not move. At present, most of dipping systems adopted in hospitals generally comprise a special dipping room, a special dipping bathtub and a special lifting and carrying device, wherein a stretcher bed matched with the dipping bathtub is arranged in the dipping bathtub, the stretcher bed is detached after each patient uses the dipping bath, and then the dipping bath is immersed in a disinfection pond for disinfection treatment, so that the problem of cross infection caused by different patients is avoided, and disinfectant in the disinfection pond is replaced after each disinfection, so that the replacement of the disinfectant is more in the whole dipping bath treatment process, and the treatment cost is relatively increased. The stretcher is fixed and integrally arranged, so that when the stretcher is detached from the immersed bathtub and put into a matched disinfection tank, the length of the disinfection tank is as long as that of the stretcher, the volume of the whole disinfection tank is very large, and the quantity of disinfection liquid used in each disinfection operation is almost the same as the inner volume of the immersed bathtub, so that the usage amount is very large.

The existing burn dipping treatment equipment is large in design, complex in structure and high in manufacturing cost, is limited by the structure of the inside of the pipeline, is very difficult to clean and disinfect each time, and is quite high in cost, so that clinical application of most basic medical units is limited.

However, during operation, the patient still has to be transferred from the patient bed to the bathing bed unit, with great inconvenience for the patient who cannot be moved. Patent document with publication number of CN207745327U discloses a medical burn wound debridement bathtub, including the dipping bath cylinder body and set up the leak protection dish in dipping bath body bottom, dipping bath cylinder body and leak protection dish are split type setting, the interior bottom surface of dipping bath cylinder body is along length direction slope setting, the dipping bath cylinder body comprises first cylinder body and second cylinder body, first cylinder body and second cylinder body are along the relative setting of length direction of dipping bath cylinder body, first cylinder body and second cylinder body peg graft, the junction of first cylinder body and second cylinder body is provided with the sealing strip, the outlet has been seted up to the side bottom of first cylinder body and second cylinder body, outlet department is provided with the sealing plug, the outlet can dismantle and be connected with the drain pipe, the outer bottom surface of first cylinder body passes through inclined plane transitional coupling with the lateral surface along length direction. The anti-leakage plate is made of aluminum alloy, so that a burn patient is easy to contact with the hard anti-leakage plate in the process of transferring the burn patient to the anti-leakage plate, the wound surface is damaged, and certain inconvenience is caused to the patient. The bath liquid of the dipping bath cannot flow circularly, and the curative effect of the medicated bath is affected to a certain extent.

At present, most burn patients cannot benefit from advanced therapy in time, and the functions of the existing dipping bath treatment equipment are simplified, so that the pain of the patients is increased and the medical resources are seriously wasted. Therefore, there is a need in the art to design a device that facilitates clinical bathing of large area burn patients.

Description of the embodiments

In the later stage of large-area burn, the residual wound surface often has a plurality of drug-resistant bacteria field planting, and the skin which is just healed has poorer anti-infection capability, is easy to secondarily infect and is easy to repeatedly burst, so that the residual wound surface brings great difficulty to clinical treatment, directly leads to prolonged hospitalization time of patients and increases treatment cost. The current research shows that 60% of wound surfaces are difficult to heal and are related to bacterial biological membranes, and bacteria can resist the actions of various antibacterial drugs through the membrane-like structure. The bathing therapy is to scrub and remove bacterial biomembrane such as wound surface dander, residual medicine, secretion and the like through the surface, thereby reducing the number of colonial planting on the wound surface and further controlling local infection. Meanwhile, the bathing promotes local blood circulation through warm water, promotes toxin excretion and inflammation elimination, creates a clean and moist microenvironment, promotes cell and epithelial growth, and promotes healing of residual wound surfaces. In addition, the dipping bath can also lead the active movement of the patient to save labor, increase the movement range of each joint and be beneficial to functional exercise and rehabilitation.

The traditional dipping bath therapy is to immerse a patient into a bathtub containing liquid medicine by lifting a stretcher through a lifting appliance, control a dipping bath treatment room, prevent the time of the first dipping bath from exceeding 30 minutes, and then properly prolong the dipping bath time according to the illness state of the patient. The long-time dipping bath can submerge the liquid medicine in the burn and scald area, so that the epidermal cells are soaked in the liquid medicine to be beneficial to recovery, but because a large number of skin cells and capillaries of a burn and scald patient are damaged, the oxygen supply of the skin cells still having activity is insufficient, the skin cells also depend on contact air to assist respiration (the horny layer of the skin is the most important way for absorbing gas by the skin, the physical property of the horny layer is quite stable, a complete semi-permeable membrane is formed on the surface of the skin, the gas is combined with water molecules under certain conditions and enters the cells through the cell membranes, whether the living or dead keratinocytes have semi-permeability, the permeability rate of substances in unit time and unit area is in proportion to the concentration of the substances in the low concentration, and the skin cells soaked in the liquid medicine for a long time cannot be contacted with air, so that the skin cells cannot directly breathe outside, and the oxygen supply of the capillaries are not sufficient, and the normal oxygen supply of the soaked burn and scald area cells is affected.

In view of this problem, several devices capable of repeatedly immersing damaged skin are provided below with reference to the accompanying drawings, each of which may be provided with a timing immersion manner (full immersion, half immersion, and flushing only), an immersion frequency and a period of time, etc. are controlled according to the lying time.

Example 1: a bathing equipment for burn and scald rehabilitation provides self-help and automatic nursing functions based on image processing technology. The structure of the device can be seen from fig. 1, in which a flat net support body capable of bearing the weight of a patient and comprising meshes is transversely arranged in the middle part of the bathtub 1, specifically, inner support walls 9 protruding outwards are respectively arranged below the inner peripheral side walls of the bathtub 1, a transverse support 2 is fixedly arranged above the inner support walls 9, and a flat net layer 3 is fixedly arranged above the transverse support 2, as shown in fig. 2.

A middle partition plate 12 is arranged in the longitudinal direction in the middle of the medicine liquid chamber 4 below the flat net support body, and the middle partition plate 12 divides the medicine liquid chamber 4 into a left medicine chamber 10 and a right medicine chamber 11 as shown in fig. 3. The liquid pushing plates 5 are respectively transversely arranged in the left and right medicine chambers, and the liquid pushing plates in the left and right medicine chambers are respectively controlled to synchronously reciprocate.

As can be seen in fig. 3, guide wheels 8 are installed near the four vertex angle positions of the liquid medicine chamber respectively through vertical wheel shafts 7, so that two groups of four wheel shafts and four guide wheels are formed, the four guide wheels 8 of the same group are sleeved with annular steel wire ropes 6, the two groups of annular steel wire ropes 6 are distributed and are intersected with the liquid pushing plate 5 to be fixed together, the guide wheels 8 or the annular steel wire ropes 6 in the two groups of guide wheels are driven by a power mechanism to rotate reciprocally, wherein the guide wheels 8 or the annular steel wire ropes 6 are driven by the power mechanism (for example, one guide wheel is driven by a motor to rotate, or the annular steel wire ropes are driven by an electric push rod to reciprocate), and thus the liquid pushing plate in the left and right medicine chamber is driven to reciprocate.

Therefore, when the left liquid pushing plate and the right liquid pushing plate reciprocate respectively, the pushed liquid medicine is made to rush out from the lower direction of the flat net support body and to fluctuate from left to right and from right to left above the flat net support body. As shown in fig. 4, the left (upper) liquid pushing plate moves forward, the right (lower) liquid pushing plate moves backward, so that the liquid medicine in the left liquid medicine chamber is pushed forward and pushed to the upper side of the flat screen layer, the liquid medicine behind the left liquid medicine chamber is reduced, and likewise, the liquid medicine in the right liquid medicine chamber is pushed backward and pushed to the upper side of the flat screen layer, the liquid medicine in front of the right liquid medicine chamber is reduced. Thus, the liquid medicine flowing out from the front of the left liquid medicine chamber flows to the front of the right liquid medicine chamber through the flat net layer, and the liquid medicine flowing out from the rear of the right liquid medicine chamber flows to the rear of the left liquid medicine chamber. The process of turning the front liquid medicine from left to right and the back liquid medicine from right to left realizes the function of flushing the liquid medicine by left and right fluctuation.

The liquid pushing plates in the left and right medicine chambers are respectively controlled to reciprocate simultaneously, namely, the liquid pushing plates in the left and right medicine chambers simultaneously move forwards and backwards simultaneously, so that the pushed liquid medicine is flushed upwards from the lower part of the flat net support body and fluctuates forwards and backwards and forwards from the upper part of the flat net support body.

The camera is arranged outside the bathtub or at the edge of the bathtub, a coordinate system is established for the bathtub through data processing after the camera shoots the bathtub, the camera is used for capturing the position of a patient in the coordinate system and the range of a burn and scald area of the patient in the state before and after lying, and the processor enables the fluctuation process of the liquid medicine to occur in the burn and scald area of the patient through controlling the driving mechanism according to the range of the coordinate system of the burn and scald area.

Based on the above configuration, with the liquid level of the liquid medicine in the bathtub controlled, full immersion, half immersion, and only flushing of various medicated bath modes can be achieved. After the patient enters the bathtub, the patient can help to pad the head, the trunk and the limbs of the patient are completely immersed in water. For patients with burn of head and face, the head and face should be cleaned first, and then the trunk, limbs, etc. should be cleaned. The softened crust or eschar is removed with sterile scissors, but forced removal is avoided. The wave flushing mode is used, so that the problem of skin respiratory resistance caused by the fact that the skin just healed cannot be repeatedly contacted with air due to long-time soaking under the liquid surface can be prevented. The cleaning effect of repeatedly fluctuating the wound surface is beneficial to cleaning and drainage of burn wound surfaces, cleaning necrotic tissues, reducing the content of bacteria and toxins, improving the blood circulation of the whole body and promoting healing of some intractable small wound surfaces.

Example 2: based on the embodiment 1, the fluctuation range of the left and right liquid pushing plates is controlled to be near the corresponding wound surface instead of the full bathtub fluctuation according to the position of the coordinate system where the wound surface of the burn and scald of the patient is captured by the camera. Thus, the effective fluctuation efficiency can be fully applied to the skin near the wound surface, and the fluctuation frequency and effect can be improved. In order to realize the function, the corresponding liquid pushing plate needs to be transferred to a coordinate area close to the wound surface in an automatic control mode, and the liquid pushing plate repeatedly fluctuates in the area.

The control mode of driving the left and right liquid pushing plates to move forwards and backwards simultaneously needs to control the steel wire rope to be fixed or contacted and fixed with the corresponding liquid pushing plates, for example, the two are fixed or unlocked through electromagnetic pliers.

In the embodiment, after the range of the bathtub coordinate system where the wound surface is positioned is determined through the camera and the processing system, the left and right liquid pushing plates are controlled to move to reach the determined range of the coordinate system, and the range is used as a target area for reciprocating wave making movement, so that the wound surface is repeatedly washed by liquid medicine. The image processing is to collect the area, the area and the degree of the burns and scalds of the human body to perform water immersion coverage or local flushing. And has memory function, and the image acquisition and processing can also diagnose the rehabilitation degree and the medicated bath effect.

Example 3: a control mode for driving the left and right liquid pushing plates to move forward and backward simultaneously is shown in fig. 8, wherein a rope passing hole seat 21 is arranged on a plate body of the liquid pushing plate 5, and a locking and releasing mechanism 22 is sleeved in the rope passing hole seat 21. The specific structure of the locking mechanism 22 is shown in fig. 9-12, and it can be seen that the mechanism comprises a closed cylindrical shell, two ends of the inner cavity of the cylindrical shell are provided with conical cavities 23, and fan-cone sliding blocks 24 are sleeved in the conical cavities 23. Specifically, a plurality of radial partition plates 27 are uniformly distributed in the conical cavity 23, a plurality of independent fan cone areas are formed among the radial partition plates 27, and each fan cone sliding block 24 is sleeved in the corresponding fan cone area respectively. An electromagnet 25 is fixed in the middle annular cavity of the inner cavity of the cylindrical shell, and the on-off condition of the electromagnet is controlled by the processor. When the electromagnet is electrified, the fan-cone sliding blocks 24 can be attracted and separated from the conical cavity 23, and in the non-electrified state of the electromagnet, the annular steel wire rope slides in the axial direction in the center of the cylindrical shell to drive the fan-cone sliding blocks 24 to enter the conical cavity 23, so that each fan-cone sliding block 24 radially presses the annular steel wire rope 6 to be locked.

In general, the axial movement of the wire rope can drive each fan-cone slider 24 to move forward, and because of the existence of two symmetrical fan-cone regions, the wire rope can drive one of the fan-cone sliders 24 to move forward or backward (the other fan-cone slider 24 moves out of the conical cavity 23 without any constraint function), and after being pressed by the conical cavity 23, each fan-cone slider 24 presses the wire rope radially inwards. In particular, in the case where the inside of the fan cone slider 24 includes the friction surface 29, as shown in fig. 13. However, in order to ensure that each fan cone slider 24 can enter the corresponding fan cavity position in a natural state, a spring 26 is connected between the fan cone slider 24 and the electromagnet, as shown in fig. 10, a spring seat 28 is provided on the inner side surface of each fan cone slider 24 to be sleeved with the spring 26.

The liquid pushing plate is meshed with the steel wire rope through the locking and releasing mechanism 22, the liquid pushing plate is released after being driven by the steel wire rope to reach the specified target range, and the two liquid pushing plates are simultaneously meshed and locked after the other liquid pushing plate is also driven to reach the specified target range. The motor is controlled to make the steel wire rope reciprocate, and the reciprocating range is limited by the target range. The fluctuation function of the mode of controlling the liquid pushing plate to reciprocate after reaching the target range also solves the problem of low liquid medicine utilization rate caused by large volume of the traditional hydrotherapy groove.

Example 4: on the basis of the embodiments 1-3, the device which can flexibly change the liquid level of the liquid medicine in the bathtub is provided by further improvement. Therefore, in the medicine dipping treatment process, the liquid level of the medicine liquid can be repeatedly changed to realize the full-dipping, half-dipping and non-dipping states, and the fluctuation function is added, so that the fluctuation control under the three states is realized, and the fluctuation medicine dipping treatment for different wound surfaces in the range and the height is realized.

The above functions of the embodiment are achieved by adopting the structure shown in fig. 6, it can be seen that a buffer chamber 13 is fixed below or on the side of the liquid medicine chamber 4, the head end of the buffer chamber 13 is communicated with the liquid medicine chamber through a liquid inlet 19, the tail end of the buffer chamber 13 is provided with an air inlet and outlet 20, a piston body 15 is sleeved in the buffer chamber 13 in a matched manner, a screw sleeve 16 is fixed in the middle of the piston body 15, a screw rod 14 is installed in the screw sleeve in a matched manner, two ends of the screw rod are installed at the centers of two end walls of the buffer chamber 13 through shaft sleeves 17, and one end of the screw rod 14 is led out of the buffer chamber 13 and then is in transmission connection with a motor 18.

The embodiment is particularly suitable for bathtub-like appliances for medicated bath treatment or nursing of patients with burns and scalds in whole body or large area, and can be laid in a waterless state, drained or fluctuated and washed after slight turning.

Example 5: based on embodiment 3, a control mode of driving the left and right liquid pushing plates to move forward and backward simultaneously is realized by utilizing the structure of embodiment 3, namely, the left and right liquid pushing plates move to the same position (on the same straight line), and when the steel wire rope is controlled to reciprocate, the left and right liquid pushing plates can be driven to move forward and backward simultaneously.

As shown in fig. 7, a pair of guide wheels and three pairs of guide wheels are respectively arranged at the front and rear ends of the left and right medicine chambers, after the annular steel wire ropes 6 are wound around the guide wheels in a reciprocating manner, three steel wire ropes are arranged in one medicine chamber, one steel wire rope is arranged in the other medicine chamber, rope passing hole seats 21 corresponding to the steel wire ropes are respectively arranged on the liquid pushing plates 5 in the medicine chambers, corresponding locking mechanisms 22 are respectively sleeved, and the locking mechanisms are respectively controlled to lock or release the corresponding steel wire ropes. The liquid pushing plates in the left and right medicine chambers are respectively controlled to synchronously reciprocate, so that the pushed liquid medicine flows out from the lower direction of the flat screen support body, and fluctuates from left to right and right to left above the flat screen support body, and the liquid pushing plates in the left and right medicine chambers are respectively controlled to synchronously reciprocate, so that the pushed liquid medicine flows out from the lower direction of the flat screen support body and fluctuates from front to back or from back to front above the flat screen support body. This control drives the left and right pusher plates simultaneously forward and backward, one pusher plate being shown in fig. 8 and the other pusher plate being shown in fig. 17. A rope passing hole seat 21 is arranged on the plate body of each liquid pushing plate, and a locking mechanism 22 is sleeved in the rope passing hole seat 21.

The specific structure of the locking mechanism 22 is shown in fig. 9-12, and it can be seen that the mechanism comprises a closed cylindrical shell, two ends of the inner cavity of the cylindrical shell are provided with conical cavities 23, and fan-cone sliding blocks 24 are sleeved in the conical cavities 23. Specifically, a plurality of radial partition plates 27 are uniformly distributed in the conical cavity 23, a plurality of independent fan cone areas are formed among the radial partition plates 27, and each fan cone sliding block 24 is sleeved in the corresponding fan cone area respectively. An electromagnet 25 is fixed in the middle annular cavity of the inner cavity of the cylindrical shell, and the on-off condition of the electromagnet is controlled by the processor. When the electromagnet is electrified, the fan-cone sliding blocks 24 can be attracted and separated from the conical cavity 23, and in the non-electrified state of the electromagnet, the annular steel wire rope slides in the axial direction in the center of the cylindrical shell to drive the fan-cone sliding blocks 24 to enter the conical cavity 23, so that each fan-cone sliding block 24 radially presses the annular steel wire rope 6 to be locked.

The axial movement of the steel wire rope can drive each fan cone sliding block 24 to move forwards, and because of the existence of the left and right symmetrical fan cone areas, the steel wire rope can drive one side of the fan cone sliding blocks 24 to move into the conical cavity 23 no matter moving forwards or backwards, and after being pressed by the conical cavity 23, each fan cone sliding block 24 presses the steel wire rope inwards in the radial direction. The locking and releasing state of the locking and releasing mechanism and the steel wire rope can be controlled by controlling the on-off condition of the corresponding electromagnet, so as to control whether the corresponding liquid pushing plate is fixed with the steel wire rope. The locking mechanism 22 located in the middle in fig. 17 must be fixed to the wire rope, and the locking mechanisms 22 located on both sides may not be fixed to the wire rope, or the locking mechanism 22 may not be installed, or may be fixed to the wire rope. As shown in the arrow directions in fig. 7, when the control makes part of the locking and releasing mechanism 22 fixed with the steel wire rope, the other part of the locking and releasing mechanism 22 is controlled to be separated from the steel wire rope, so that the synchronous forward and synchronous backward movement functions of the liquid pushing plates at two sides are realized.

Example 6: on the basis of the above embodiments, the relationship between the liquid pushing plate and the bathtub can also adopt a structural form as shown in fig. 14-16, roller seats 31 are arranged on the left and right side walls of the liquid pushing plate 5, rollers 32 are mounted on the left and right side walls through pin shafts, meanwhile, guide rails 33 are arranged on the inner wall of the bathtub, and each roller 32 is respectively sleeved in the corresponding guide rail 33.

Example 7: on the basis of the embodiment 3, two guide wheels 8 are further arranged near the four vertex angles of the liquid medicine chamber through two vertical wheel shafts 7 respectively, so that two groups of four wheel shafts and four guide wheels are formed, as shown in fig. 18.

The four guide wheels 8 of the same group are sleeved with annular steel wire ropes 6 in a ring mode, each liquid pushing plate 5 is provided with two rope passing hole seats 21 respectively and is sleeved with corresponding locking and releasing mechanisms 22 respectively, the two groups of annular steel wire ropes 6 penetrate through the centers of the corresponding locking and releasing mechanisms 22 respectively, and the guide wheels 8 or the annular steel wire ropes 6 in the two groups of guide wheels are driven by independent driving mechanisms to rotate in a reciprocating mode respectively.

The embodiment has multiple functions, (1) when one locking and releasing mechanism on the same liquid pushing plate is controlled to fix the steel wire rope, and the other locking and releasing mechanism releases the steel wire rope, the liquid pushing plates in the left and right medicine chambers are respectively controlled to synchronously reciprocate, so that the pushed liquid medicine flows out from the lower part of the flat net support body upwards and fluctuates from left to right and from right to left above the flat net support body. (2) When two locking and releasing mechanisms on the same liquid pushing plate are controlled to fix the steel wire ropes, the liquid pushing plates in the left and right medicine chambers are respectively controlled to reciprocate simultaneously, so that the pushed medicine liquid flows out upwards from the lower part of the flat net support body and fluctuates from front to back and back to front from the upper part of the flat net support body.

Accordingly, any modification, equivalent replacement, improvement, etc. made without departing from the spirit and scope of the present invention should be included in the scope of the present invention. In addition to the two liquid medicine chambers and the corresponding left and right liquid pushing plates described in the above embodiments, there may be cases where there are more than two liquid medicine chambers and a plurality of liquid pushing plates. Or a plurality of parallel liquid pushing plates are arranged in the same liquid medicine chamber, and the plurality of parallel liquid pushing plates synchronously move back and forth or respectively move back and forth. For example, the cushion layer (the back side is supported and the back side is a stop block clamped on the mesh plate) of the liquid medicine can be overturned by taking the stainless steel mesh plate as a main supporting surface and containing a pillow with meshes (or elasticity) and a gasket, and the cushion block can be disassembled, assembled and spliced to form a certain supporting shape).
