Description

Technical Field

[0001] The present invention relates to the technical field of medical nursing protective gear, and in particular to a nursing protective gear for resisting cold stimulation after chemotherapy in oncology and a use method thereof. Background Art

[0002] In the field of oncology, chemotherapy is a widely used treatment method. While it is effective against tumor cells, it often brings many adverse reactions to patients. Among them, the neurotoxic side effects caused by some chemotherapy drugs are more prominent, which makes the patient's body sensitive to cold stimulation significantly enhanced. In order to prevent patients from getting cold, anti-cold stimulation nursing protective gear is usually used. For example, an anti-cold stimulation protective gear after tumor chemotherapy disclosed in application number CN202323289159.3 is to prevent patients from getting cold; Among them, chest protection is also a key point. The reason is that if the patient's chest is exposed to cold stimulation, the vasoconstriction reaction will intensify, which will not only cause the patient's chest skin surface temperature to drop rapidly, but will also further aggravate the tingling, numbness, soreness and other discomforts caused by abnormal nerve conduction, seriously affecting the patient's daily activities and rest quality, and may even interfere with the patient's breathing movements, causing great physical and mental pain and life troubles to the patient.

[0003] The existing chest protection usually uses quilts, blankets and other warming items to keep the patient's chest warm, or uses heat patches and hot water bags to keep the chest warm. However, when the patient stands up, turns over, or moves, these cannot be applied to the chest and cannot continuously and effectively provide a stable warm environment for the chest, which greatly reduces the cold stimulation protection effect. In addition, these are passive warming only when the patient has already felt cold, and cannot automatically warm the chest after the patient's chest skin temperature drops. Therefore, when the body has already felt cold, the body is already in an uncomfortable state, and the cold may cause tingling, numbness and other sensations. Even if the patient is kept warm afterwards, these uncomfortable symptoms will not disappear immediately, which will continue to affect the patient's comfort. Summary of the invention

[0012] Preferably, a method for using an anti-cold stimulation nursing protective gear after chemotherapy in oncology comprises the following steps: S1. Stick the anti-cold shell on the chest, then wrap the first connecting belt and the second connecting belt around the back, and then stick the anti-cold shell on the patient's chest through a fixing mechanism; S2. When the patient's chest temperature drops, the patient's chest is massaged through the adaptive anti-cold mechanism, and heat is transferred to the chest; S3. When the patient's temperature drops or rises, the degree of fit between the anti-cold shell and the chest is adaptively adjusted through the fixing mechanism.

[0013] Compared with the known prior art, the technical solution provided by the present invention has the following beneficial effects: 1. A detection groove is set on the outer wall where the anti-cold shell contacts the chest, and a thermistor is fixed inside. When the patient's skin temperature drops, the resistance value of the thermistor decreases, which will increase the current passed into the temperature conducting frame. The temperature conducting frame is made of solid conductive polymer. After power is turned on, the thermal conductivity is enhanced. The greater the current, the better the thermal conductivity. The temperature conducting frame is immersed in paraffin and can transfer the heat of the paraffin. At the same time, the PLC controller will control the first micro electric telescopic rod and the second micro electric telescopic rod to start, push the upper and lower sliding shells forward, make the gear mesh with the tooth plate, and drive the temperature conducting roller to fit the patient's chest through the graphene cloth. The second micro electric telescopic rod pushes the sliding block to move, so that the heat conducting roller rotates, massages the patient's chest, promotes blood circulation, and transfers heat to the patient's chest while massaging, so as to achieve the effect of automatic warming, and can take corresponding measures immediately after the patient's skin cools down.

[0014] 2. After the anti-cold shell is attached to the chest, the first connecting belt and the second connecting belt are wrapped around the back, and the fixing block is inserted into the fixing shell. The PLC controller controls the second electromagnetic plate and the first electromagnetic plate to be energized. The second electromagnetic plate adsorbs the permanent magnetic plate, and the first electromagnetic plate adsorbs the second electromagnetic plate. By controlling the current passed into the second electromagnetic plate, the first connecting belt and the second connecting belt can be tightened, so that the anti-cold shell is tightly and appropriately attached to the patient's chest without falling off or being too tight. When the thermistor detects that the patient's skin temperature has dropped, its resistance value decreases, which will increase the current passed into the first electromagnetic plate, and further tighten the first connecting belt and the second connecting belt in a small range, further ensuring that the anti-cold shell will not fall off, thereby always keeping it in the chest position to play a warming role.

[0015] 3. When the temperature conducting rack transfers the heat of the paraffin to the patient's chest, the paraffin temperature drops and it will slowly solidify and expand in volume, squeezing the first elastic airbag, so that the air in the first elastic airbag enters the second elastic airbag through the ventilation tube, and the second elastic airbag expands. An air pressure detector is set in the second elastic airbag. Pre-test shows that the air pressure is proportional to the solidification state of the paraffin. When it is detected that the air pressure is about to reach the solidification state of the paraffin, the PLC controller controls the heating rod to reheat the paraffin to melt it for subsequent use. When the paraffin is melted, the air in the second airbag can flow back into the first elastic airbag, thereby ensuring that the paraffin can continuously and effectively provide heat to the patient.

Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] The present invention will be further described below in conjunction with the embodiments.

[0021] Example: Refer to Figures 1 to 6 , a nursing protective gear for anti-cold stimulation after chemotherapy in oncology, comprising: An anti-cold shell 1, the outer walls on both sides of the anti-cold shell 1 are fixedly connected to the first connecting belt 71 and the second connecting belt 72 respectively, the inner wall of the anti-cold shell 1 is fixedly connected with a baffle 2, the outer wall of the baffle 2 is provided with a connecting groove 3 for moving the temperature conducting frame 62, a paraffin chamber 4 and an operation chamber 5 are formed between the anti-cold shell 1 and the baffle 2, paraffin is poured into the paraffin chamber 4, the heating rod 61 is arranged in the paraffin of the paraffin chamber 4, and an insulation board is arranged on the inner wall of the paraffin chamber 4. When the outside air temperature is lower than its own melting point, the paraffin will slowly release heat and solidify. Therefore, an insulation board is arranged in the paraffin chamber 4. The purpose is to prevent the paraffin from automatically releasing heat when it is not needed, resulting in heat loss.

[0022] The anti-cold shell is attached to the patient's chest by the fixing mechanism 7, referring to Figure 1 , Figure 2 The fixing mechanism 7 includes a first connecting belt 71 and a second connecting belt 72 for binding on both sides and the back of the patient, a fixing block 73 is provided at one end of the first connecting belt 71 and the second connecting belt 72 close to each other, and a fixing shell 74 for fixing the fixing block 73 is provided at one end of the second connecting belt 72 close to the first connecting belt 71; Among them, the fixing mechanism 7 also includes a connecting block 75 fixedly connected to the end of the first connecting belt 71 away from the anti-cold shell 1, the outer wall of the connecting block 75 is fixedly connected to the fixed block 73, the inner wall of the fixed shell 74 is fixedly connected to the first electromagnetic plate 76, the fixed shell 74 is slidably connected to the second electromagnetic plate 77 that is magnetically attracted to the first electromagnetic plate 76, the outer wall of the connecting block 75 close to the fixed shell 74 is fixedly connected to a permanent magnet plate 78 that is magnetically attracted to the second electromagnetic plate 77, a fixing spring 79 is fixedly connected between the second electromagnetic plate 77 and the first electromagnetic plate 76, the outer wall of the fixed block 73 is slidably connected to the inner wall of the fixed shell 74, the PLC controller is electrically connected to the second electromagnetic plate 77, and the thermistor 620 is electrically connected to the first electromagnetic plate 76 to form a fixed loop.

[0023] The adaptive anti-cold mechanism 6 can immediately protect the patient's chest when the patient's skin cools down. Figures 2 to 5 The adaptive anti-cold mechanism 6 includes paraffin for continuous heat release, a heating rod 61 for heating the paraffin is arranged in the paraffin, a temperature conducting frame 62 made of a solid conductive polymer is immersed in the paraffin, an arc-shaped heat conducting plate 63 is fixedly connected to the other end of the temperature conducting frame 62, and the inner peripheral wall of the arc-shaped heat conducting plate 63 is rotatably contacted with a heat conducting roller 64 for massaging the patient's chest. The thermal conductivity of the solid conductive polymer usually increases after being energized, and the thermal conductivity is relatively poor when not energized, for the following reasons: Unlike metals that rely on free electrons and inorganic non-metals that rely on phonons to conduct heat, ordinary polymers have disordered molecular chains and weak interactions, making it difficult to effectively transfer heat. They have low thermal conductivity and are poor conductors of heat, such as common plastics and rubbers. When solid conductive polymers are not energized, the number of internal carriers is small and the mobility is low, making little contribution to heat transfer. Thermal conduction mainly relies on the movement of molecular chain links and segments, but the transfer effect is poor and the thermal conductivity is poor. After power is applied, the carriers inside the solid conductive polymer move in a directional manner under the action of the electric field to form an electric current. These carriers interact with the polymer molecular chains and lattices during the migration process, transferring heat while transferring charge, thereby enhancing thermal conductivity. When current passes through, part of the electrical energy is converted into thermal energy due to the resistance of the polymer, causing the material temperature to rise. According to the law of heat conduction, the temperature difference inside the material will cause heat to be transferred from the high temperature area to the low temperature area, which is manifested as an increase in thermal conductivity on a macro scale. And because the greater the amount of current flowing through a solid conductive polymer, the better its thermal conductivity. Because when the amount of current flowing through it increases, on the one hand, the speed of directional movement of carriers increases, the frequency of collision with polymer molecular chains and lattices increases, and the efficiency of heat transfer is improved; on the other hand, according to Joule's law, more heat is generated, which increases the temperature difference inside the material, increases the thermal conduction power, and accelerates the thermal conduction rate.

[0024] Among them, the adaptive anti-cold mechanism 6 also includes a fixing frame 65 fixedly connected to the position of the anti-cold shell 1 close to the chest, the inner wall of the fixing frame 65 is fixedly connected to the graphene cloth 66, the outer wall of the fixing frame 65 on the side away from the chest is fixedly connected to the tooth plate 67, the outer wall of the baffle 2 on the side close to the tooth plate 67 is provided with a moving groove 69, the inner wall of the moving groove 69 is slidably connected to a moving block 68, and a connecting spring 610 is fixedly connected between each temperature conducting frame 62 and the moving block 68 close to itself, wherein the graphene cloth 66 has excellent thermal conductivity, it can conduct heat quickly, and can well preserve the heat emitted by the human body, which has a good warming effect, and the graphene cloth 66 has good air permeability, because graphene has a unique two-dimensional structure, it will not block the fiber gaps of the cloth, and in the process of making the cloth, graphene is usually added by combining with fiber materials, and this combination method will not affect the pore structure of the cloth itself, so it will not make the chest stuffy while keeping the patient's chest warm.

[0025] Among them, two groups of first micro-electric telescopic rods 611 symmetrically arranged in upper and lower directions are fixedly connected to the outer wall of one side of the baffle 2 near the tooth plate 67, and the telescopic ends of the two groups of micro-electric telescopic rods are fixedly connected to the sliding shell 613, and the inner wall of the sliding shell 613 is slidably connected to a plurality of sliding blocks 614 arranged equidistantly, and a connecting rod 615 is fixedly connected between every two sliding blocks 614 close to each other, and the inner wall of the sliding shell 613 is fixedly connected to the second micro-electric telescopic rod 612, and the telescopic end of the second micro-electric telescopic rod 612 is fixedly connected to one of the sliding blocks 614 close to itself, and the bottom ends of the plurality of sliding blocks 614 at the top are rotatably connected to the first rotating rod 616, The outer wall of the first rotating rod 616 is fixedly connected with a gear 618, and the gear 618 is magnetically meshed with the tooth plate 67, and the top ends of the multiple sliding blocks 614 below are rotatably connected with the second rotating rod 617, and the first rotating rod 616 and the second rotating rod 617 are fixedly connected to the heat-conducting roller 64; the outer wall of the anti-cold shell 1 that contacts the chest is provided with a detection groove 619, and the inner wall of the detection groove 619 is fixedly connected with a thermistor 620, and the electrical signals of the thermistor 620, the first micro electric telescopic rod 611, and the second micro electric telescopic rod 612 are connected with a PLC controller to form a regulation loop, and the thermistor 620 is electrically connected to the temperature conducting rack 62 to form a temperature conducting loop.

[0026] A first elastic airbag 621 is provided at the inner bottom of the paraffin chamber 4, and the first elastic airbag 621 is immersed in paraffin. A second elastic airbag 622 is provided at the inner top of the paraffin chamber 4, and an air pressure detector is provided in the second elastic airbag 622. Air is infused into the first elastic airbag 621 and the second elastic airbag 622. A ventilation pipe 623 is fixedly connected between the first elastic airbag 621 and the second elastic airbag 622, and a pressure valve is provided in the ventilation pipe 623. The air pressure detector, the heating rod 61 and the PLC controller are electrically connected to form a heating circuit.

[0027] The working principle of the present invention is as follows: First, attach the anti-cold shell 1 to the chest, wind the first connecting belt 71 and the second connecting belt 72 around the back, insert the fixing block 73 into the fixing shell 74, and control the second electromagnetic plate 77 and the first electromagnetic plate 76 to be energized through the PLC controller, so that the permanent magnetic plate 78 is adsorbed by the second electromagnetic plate 77, and the first electromagnetic plate 76 is adsorbed by the second electromagnetic plate 77, and the current passed into the second electromagnetic plate 77 is controlled by the PLC controller to tighten the first connecting belt 71 and the second connecting belt 72, so that the anti-cold shell 1 is attached to the patient's chest and cannot fall off or be too tight; The temperature of the patient's chest is monitored in real time by the thermistor 620. When the patient's skin temperature decreases, the resistance value of the thermistor 620 decreases, thereby increasing the current passed into the first electromagnetic plate 76, and further tightening the first connecting belt 71 and the second connecting belt 72 in a small range. The purpose is to prevent the anti-cold shell 1 from being in close contact with the chest, and then prevent the graphene cloth from being in contact with the chest, so that the heat preservation effect cannot be achieved (the graphene cloth has a heat preservation effect, the prior art), and the patient's chest can be further kept warm by the anti-cold shell 1; The first micro electric telescopic rod 611 and the second micro electric telescopic rod 612 are started by the PLC controller, and then the upper and lower sliding shells 613 are pushed forward by the first micro electric telescopic rod 611 (the moving distance is the position where the gear 618 and the tooth plate 67 are meshed after pre-testing), so that the gear 618 is meshed with the tooth plate 67, and at the same time, the heat-conducting roller 64 is fitted with the patient's chest through the graphene cloth 66. After the gear 618 is meshed with the tooth plate 67, one of the sliding blocks 614 is pushed forward by the second micro electric telescopic rod 612, and the connecting rod 615 is driven to move synchronously by one of the sliding blocks 614, so that all the sliding blocks 614 are moved synchronously, and then the first connecting rod 615, the second connecting rod 615, and the heat-conducting roller 64 are driven to move synchronously, and the heat-conducting roller 64 is rotated by the meshing of the gear 618 and the tooth plate 67, so as to massage the patient's chest, promote blood circulation through massage, and warm the patient's chest.

[0028] At the same time, the resistance value of thermistor 620 decreases, which will increase the current passed into the temperature conducting frame 62. When current is passed into the temperature conducting frame 62, the thermal conductivity of the temperature conducting frame 62 will gradually increase. The greater the current passed, the better the thermal conductivity (the reason is specifically explained in the above introduction to solid conductive polymers). Therefore, the heat of the paraffin is transferred to the heat conducting roller 64 through the temperature conducting frame 62. While the heat conducting roller 64 massages the patient, the heat is transferred to the patient's chest, further warming the patient's chest, thereby achieving an anti-cold effect.

[0029] As the temperature conducting rack 62 transfers the heat of the paraffin to the patient's chest, the temperature of the paraffin will slowly drop, so the paraffin will slowly squeeze the first elastic airbag 621. The reason is that the volume of the paraffin slowly expands during the solidification process. This is because the distance between the molecules of the paraffin is relatively small when it is in a liquid state, and the intermolecular force is mainly the van der Waals force. The molecules can move relatively freely. When the paraffin solidifies, the molecules gradually form a relatively regular but loose structure, and the average distance between the molecules becomes larger, resulting in volume expansion. Therefore, the first elastic airbag 621 in the paraffin will be gradually squeezed by the paraffin that expands in volume during the solidification process, so that the air in the first elastic airbag 621 passes through the ventilation. Tube 623 enters the second elastic airbag 622, thereby expanding the second elastic airbag 622, and then the air pressure in the second elastic airbag 622 is detected by an air pressure detector (the air pressure is proportional to the solidification state of the paraffin after pre-testing), wherein the air pressure detector is sufficient to accurately detect the air pressure. When it is detected that the air pressure is about to reach the solidification state of the paraffin, the heating plate is immediately controlled by the PLC controller to reheat the paraffin to melt it for subsequent use. After the paraffin melts, the gas in the second elastic airbag 622 will return to the first elastic airbag 621. Because the first elastic airbag 621 is not squeezed by external force, the air in the second airbag can return to the first elastic airbag 621.
