Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular is a patient cooling device for respiratory nursing. Background Art

[0002] In respiratory care, when caring for patients with high fever or patients who need mild hypothermia treatment, the patient needs to be cooled down. Continuous high fever can lead to serious complications such as increased cardiac load, increased oxygen consumption, cerebral hypoxia and edema. Therefore, taking effective cooling measures for patients with persistent high fever as soon as possible is of great significance to protecting brain tissue and reducing damage to important organs. The cooling methods mainly include whole body cooling and local cooling.

[0003] General cooling methods include drug cooling and physical cooling. In most cases, physical cooling is considered the preferred method of cooling due to its high safety, wide applicability, and rapid and effective characteristics. Cooling blankets and ice packs are the two most common cooling methods in physical cooling. When using ice packs, it is necessary to avoid direct contact with the skin to avoid frostbite. At the same time, if the ice pack is damaged or leaks, the liquid in it may cause irritation or harm to the human body. The use of cooling blankets only requires medical staff to spread the cooling blanket on the patient and adjust the temperature to an appropriate level. Therefore, cooling blankets are safer overall.

[0004] Since the cooling blanket has a cooling effect through internal circulating water flow, and then heat is exchanged between the circulating water and the human body to achieve the effect of heat dissipation, the patient's fever and sweating will cause water vapor to exist in the heat exchange environment. With the condensation effect of the heat exchange, liquid water will condense and flow on the patient's skin or in the device. The evaporation of liquid water will lower the temperature, making it impossible for the device to accurately measure the patient's current body temperature and control the temperature of the circulating water. The loss of control of the circulating water temperature by the cooling device may cause the patient's body temperature to drop excessively, causing secondary damage. Therefore, it is necessary to propose a patient cooling device for respiratory nursing that can reduce the impact of sweat on temperature detection and control during the cooling process. Summary of the invention

[0005] In order to solve the above problems, the purpose of the present invention is to provide a patient cooling device for respiratory care, which can reduce the influence of liquid water such as sweat on the detection of body temperature and the control of cooling target temperature without reducing the cooling effect through a water-absorbing layer.

[0006] In order to achieve the above-mentioned purpose, the technical scheme of the present invention is as follows: A patient cooling device for respiratory care, comprising a control unit and a cooling unit, wherein an intelligent system is arranged in the control unit, and the intelligent system is electrically connected to the cooling unit, the cooling unit comprising a pad for the patient to lie on, elastic insulation blocks for covering and fitting the patient's skin are fixedly connected on both sides along the length direction, a strap assembly is arranged above the insulation block, a cooling assembly for heat exchange with the patient's skin is sleeved on the outer wall of the insulation block, a support shell is sleeved on the outside of the cooling assembly, a 'U'-shaped water-absorbing layer is arranged above the pad, the bottom of the water-absorbing layer is fitted with the top of the pad, the outer walls of the water-absorbing layer on both sides are respectively fitted with the outer walls of the support shells on both sides, and the water-absorbing layer is composed of a water-absorbing outer shell and a water-absorbing filler.

[0007] The principle of the basic solution is: to connect the insulation blocks on both sides through the pad, to isolate the heat exchange on both sides of the insulation blocks through the insulation blocks, to adapt the device to patients of different body shapes through the strap assembly, to cool the patients through the cooling assembly, and to absorb liquid water produced by sweating, heat exchange and condensation during the cooling process through the water absorption layer.

[0008] The beneficial effects of the basic solution are: 1. Since the insulation layer has insulation capabilities and is a porous material with a soft texture, the insulation block has elastic plasticity, so that the insulation block can be bent to fit the patient's skin, increasing the heat exchange and cooling effect of the cooling component located inside the insulation block.

[0009] 2. Since the water-absorbing filler can absorb and combine the liquid water in the cooling process, the probability of the water-absorbing layer being squeezed by the patient's body movement and the leakage of liquid water affecting the cooling effect is reduced, thereby improving the practicality of the device.

[0010] 3. Since the water-absorbing layer will expand and change its volume after absorbing water, after the patient's fixing strap assembly fits the skin, the expanded water-absorbing layer will exert outward pressure on the supporting shell, causing the cooling assembly inside the supporting shell to be squeezed and deformed, thereby accelerating the heat exchange inside the insulation block. Compared with conventional cooling blankets, it can not only reduce the influence of liquid water such as sweat on the cooling effect, but also improve the cooling efficiency of the device through the expansion caused by liquid water.

[0011] Furthermore, the cooling component includes a water pipe and a water pump. The water pipe is connected end to end and is wrapped around the outer walls on both sides of the insulation block. A number of cooling plates are provided on the wall of the water pipe on the side of the insulation block away from the pad. The water pump is connected to the water pipe.

[0012] The beneficial effect of the basic scheme is: by setting water to circulate in the water pipe, the circulating water can exchange heat with the skin on the inner side of the insulation block to cool the human body, and exchange heat with the air on the outer side of the insulation block to cool the water flow. At the same time, a number of refrigeration plates are set to cool the water flow, and the coordinated cooling improves the cooling efficiency of the device.

[0013] Furthermore, the support shells are all made of silicone material, and a pipe groove for fixing the water pipe is opened on one side of the support shell close to the insulation block.

[0014] The beneficial effect of the basic solution is: because when the water pipe is deformed and bent due to excessive pressure, it will cause the water pipe to be blocked and the device will not be able to achieve the cooling effect. Through the characteristics of the silicone material of the support shell, it can offset part of the pressure when the water pipe is squeezed, rather than squeezing and blocking the water pipe, so that the pressure can achieve a beneficial effect on the cooling process and improve the practicability of the device.

[0015] Furthermore, a temperature sensor is fixedly connected to one side of the support shell close to the width direction of the pad.

[0016] The beneficial effect of the basic solution is: since the rise in human body temperature can be most accurately detected by detecting oral temperature and axillary temperature, by setting the temperature sensor on one side of the support shell, when the patient is cooled down, this position just corresponds to the patient's armpit, thereby improving the accuracy of temperature detection during the process and facilitating the doctor's judgment on the cooling effect of the patient.

[0017] Furthermore, the water pipe is composed of a first water pipe group, a second water pipe group and a plurality of connecting pipes, and the first water pipe group and the second water pipe group are symmetrically arranged on both sides of the insulation block;

[0018] The first water pipe group is fixedly connected with the second water pipe group through a connecting pipe. The first water pipe group and the second water pipe group both include a number of corresponding straight pipes and branch pipes. The straight pipes are interconnected to form a broken line shape. The branch pipes are all curved pipes. Adjacent branch pipes are connected with the corresponding straight pipes in an up-and-down staggered manner.

[0019] The beneficial effects of the basic scheme are: 1. When water flows through the first water pipe group, the design of straight pipes and curved pipes can accelerate the water flow, thereby achieving fast and efficient heat exchange cooling and improving the practicality of the device.

[0020] 2. When the water flow located on the outer wall of the insulation block passes through the second water pipe group in the opposite direction of the relative flow direction, water reflux occurs, causing a flow blocking effect, hindering the overall forward flow of the water, slowing down the flow rate of the water through the outer wall of the insulation block, improving the control of the water flow temperature, and improving the cooling effect of the refrigeration plate on the water flow.

[0021] Furthermore, the water pump is fixedly connected to the side wall of the support shell close to the temperature sensor, the water pump input end is detachably connected to the straight pipe located closest to the outer wall of the insulation block, and the water pump output end is detachably connected to the straight pipe located closest to the inner wall of the insulation block.

[0022] The beneficial effect of the basic solution is: through the restriction of water flow direction by the water pump and the design of the curved pipe, the water flows faster on the inner wall of the insulation block and slower on the outer wall of the insulation block, that is, the water exchanges heat with the skin to lower the body temperature quickly while the water exchanges heat with the outside air to lower the water temperature slowly.

[0023] Furthermore, a plurality of refrigeration fins are fixedly connected to the junction of the straight pipe and the branch pipe at equal intervals.

[0024] The beneficial effect of the basic solution is: because the outer wall of the insulation block is designed with a bend to slow down the water flow, all water flows through the intersection of the bends. By designing the refrigeration plate at the intersection of adjacent bends, the efficiency of heat exchange between the refrigeration plate and the water flow to reduce the water temperature can be improved.

[0025] Furthermore, the strap assembly includes a strap, which is made of elastic material and is provided with a rope buckle for adjusting the length of the strap.

[0026] The beneficial effect of the basic solution is that because different patients have different body shapes, the thermal insulation block can fit different patients through the cooperation of the straps and the cord buckles, thereby improving the practicality of the device.

[0027] Furthermore, the control unit includes a shell, and a side wall of one side of the shell is fixedly connected with a heating button, a cooling button and a display screen for displaying the patient's body temperature and the target temperature. The display screen is electrically connected to a control board, and the heating button and the cooling button are both electrically connected to the control board.

[0028] The beneficial effect of the basic plan is that because patients themselves experience the cooling effect better than doctors observe when using the device, by setting heating and cooling buttons that patients can press, patients can control the cooling target temperature themselves, reducing the probability of secondary injury to patients due to excessive cooling.

[0029] Furthermore, the intelligent system includes an acquisition module, a processing module, a driving module and a display module;

[0030] The acquisition module is used to collect and record the patient's armpit temperature data in real time to obtain the patient's real-time temperature information;

[0031] The processing module is used to convert the temperature signal into temperature data, transmit it to the display module, compare the initial body temperature of the patient with the current body temperature, comprehensively analyze whether the current device temperature needs to be increased or decreased, and transmit a temperature increase or decrease signal to the drive module;

[0032] A display module, used to receive the signal from the processing module and display the temperature data on a display screen;

[0033] The driving module is used to control the power of the refrigeration plate to control the water temperature of the circulating water after receiving the signal.

[0034] The beneficial effects of the basic solution are: after the patient's temperature data is collected by the acquisition module, the patient's body temperature is analyzed by the processing module, and then the temperature of the refrigeration plate is controlled by the driving module, so that the device can adjust the temperature by itself, thereby protecting patients whose body temperature drops quickly. At the same time, the display of temperature data is helpful for doctors to judge the patient's physical condition. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0040] The following is further described in detail through specific implementation methods:

[0041] Embodiment 1:

[0042] Basically as attached Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown: A patient cooling device for respiratory care includes a control unit and a cooling unit. The control unit is provided with an intelligent system, which is electrically connected to the cooling unit. The cooling unit includes a pad 1 for the patient to lie on, and both sides of the pad 1 along the width direction are fixedly connected by rivets with insulation blocks 2 for covering and fitting the patient's skin. The insulation block 2 is made of elastic organic fiber insulation material, which can achieve heat exchange between the inner and outer walls of the insulation block 2 without affecting each other, and at the same time enable the insulation block 2 to be shaped to fit the skin of patients of different body shapes.

[0043] A strap assembly is provided above the insulation block 2, and a cooling assembly for heat exchange with the patient's skin is provided on the outer wall of the insulation block 2. The cooling assembly includes a water pipe 401 and a water pump 402. The water pipe 401 is connected end to end and is wound around the inner and outer outer walls of the insulation block 2. A plurality of cooling plates 403 are provided on the wall of the water pipe 401 on the side of the insulation block 2 away from the pad 1. The water pump 402 is connected to the water pipe 401. A supporting shell 5 for supporting the cooling assembly is provided outside the water pipe 401. A 'U'-shaped water absorption layer 3 is provided above the pad 1. The bottom of the water absorption layer 3 is in contact with the top of the pad 1, and the outer walls on both sides of the water absorption layer 3 are respectively in contact with the outer walls 5 of the supporting shells on both sides. The 'U'-shaped water absorption layer 3 can absorb liquid water condensed due to heat exchange on both sides of the patient's body and sweat from the back.

[0044] The water-absorbing layer 3 is composed of a water-absorbing shell 801 for penetrating and absorbing water and a water-absorbing filler 302. The water-absorbing filler 302 is a highly water-absorbing resin material. The highly water-absorbing resin is a functional polymer material with extremely high water absorption and excellent water retention. It can reduce the influence of liquid water on temperature and keep the skin surface dry and comfortable. In addition, the highly water-absorbing resin has the property of swelling after absorbing water. The volume of the water-absorbing filler 302 that absorbs liquid water will increase, and the volume of the water-absorbing shell 301 will also increase due to the support force of the water-absorbing filler 302. The supporting shell 5 located on one side of the water-absorbing layer 3 is subjected to the outward pressure from the water-absorbing shell 301, so that the water pipe 401 is subjected to the pressure relieved by the water-absorbing shell 301, which can reduce the volume of the water pipe 401, accelerate the water flow rate in the water pipe 401, increase the rate of cooling heat exchange, and improve the cooling efficiency of the device.

[0045] The specific implementation process is as follows: the patient lies on the backrest 1 in the cooling stage. Since the fever caused by respiratory diseases is a whole-body fever, the patient maintains body temperature mainly by transferring heat to various parts of the body through blood flow. Therefore, covering part of the upper limbs can achieve whole-body cooling of the patient. The insulation block 2 is shaped and fixed to the patient's skin through the strap assembly, and then the device is powered on to start cooling. During the cooling process, the water in the water pipe 401 is pumped by the water pump 402 and circulates in the water pipe 401. The water passes through the outside of the insulation block 2. When the water passes through the water pipe 401 on the outer wall, the water in the water pipe 401 can reach the target cooling temperature after being cooled by a number of refrigeration plates 403. In addition, since the ward will maintain the indoor temperature below 30°C to make other patients comfortable in the hospital, the water in the water pipe 401 can also exchange heat with the outside air, thereby improving the efficiency of lowering the water temperature in the water pipe 401. When the water passes through the water pipe 401 on the inner and outer walls of the insulation block 2, it exchanges heat with the patient's skin. The heat emitted from the skin of the patient with fever is absorbed by the water in the water pipe 401, thereby achieving the effect of cooling the patient's skin.

[0046] Embodiment 2:

[0047] As attached Figure 1 and Figure 3 As shown: The difference from the above embodiment is that the support shell 5 is made of silicone material, and a pipe groove for fixing the water pipe 401 is opened on one side of the support shell 5 close to the insulation block 2.

[0048] The specific implementation process is as follows: during the cooling process, the support shell 5 plays a role of fixing and limiting the water pipe 401, reducing the probability of reducing the cooling effect due to the displacement of the water pipe 401. In addition, the support shell 5 will offset part of the pressure applied to the water pipe 401 during the cooling process, reducing the probability of failure of the cooling device due to blockage of the water pipe 401 due to the influence of the extrusion force, thereby improving the practicability of the device.

[0049] Embodiment 3:

[0050] As attached Figure 1 As shown: The difference from the above embodiment is that a temperature sensor 6 is fixedly connected to one side of the support shell 5 close to the pad 1 in the width direction.

[0051] The specific implementation process is as follows: when the patient lies down and uses the device to cool down, the two arms will be located on the two sides of the insulation blocks 2 away from each other, the body will be located above the pad, and the support shell 5 will be located between the arm and the chest. At this time, the position of the patient's armpit is opposite to one side of the support shell 5 in the width direction. The temperature sensor 6 is set at this position so that the temperature sensor 6 is located exactly under the patient's armpit. Measuring the patient's body temperature under the armpit is more accurate, which is beneficial to improving the accuracy of detecting the patient's body temperature during the cooling process.

[0052] Embodiment 4:

[0053] As attached Figure 2 As shown: The difference from the above embodiment is that the water pipe 401 is composed of a first water pipe group, a second water pipe group and a plurality of connecting pipes 413 formed in one piece, and the first water pipe group and the second water pipe group are symmetrically arranged on both sides of the insulation block 2. The symmetrical arrangement of the first water pipe group and the second water pipe group can make the directions of the first water pipe group and the second water pipe group consistent, so that the flow direction of water along the first water pipe group and the second water pipe group is different from the direction of the outer wall and the inner wall of the insulation block 2, which can achieve different flow velocities of water in the water pipe 401 on the inner and outer sides, thereby achieving different effects.

[0054] The first water pipe group is fixedly connected to the second water pipe group through a connecting pipe 413. The first water pipe group and the second water pipe group both include a plurality of corresponding straight pipes 411 and branch pipes 412. The plurality of straight pipes 411 are interconnected to form a broken line shape. The branch pipes 412 are all curved pipes. Adjacent branch pipes 412 are respectively connected to the corresponding straight pipes 411 in an up-and-down staggered manner.

[0055] The water pump 402 is welded to the side wall of the support shell 5 close to the temperature sensor 6. The input end of the water pump 402 is detachably connected to the straight pipe 411 located closest to the outer wall of the insulation block 2, and the output end of the water pump 402 is detachably connected to the straight pipe 411 located closest to the inner wall of the insulation block 2. The water pump 402 limits the flow direction of water in a number of interconnected curved pipes 411, so that the water flow presents a clockwise flow around the insulation block 2.

[0056] The specific implementation process is as follows: during the cooling process, water is divided into several streams through the angles of several straight pipes 411, and the water mainly flows in a 'Z' shape through several straight pipes 411 that are interconnected. When the water flows from the vertical part of the straight pipe 411 to the branch pipe 412 (the first water pipe group), each time the main water flow passes through a straight pipe 411, it will go up or down into the hook part of an adjacent branch pipe 412 and then flow back to the main water flow channel. This backflow will cause a blocking effect on the flow and increase the pressure head, thereby hindering the overall forward flow of the water flow and slowing down the water flow. The flow rate through the outer wall of the insulation block 2 improves the control of the water flow temperature, and reduces the ineffective cooling caused by flowing to the inner wall of the insulation block 2 before the temperature is lowered to the target cooling temperature; and when the water flows in the second water pipe group, the water flow can bypass the bends of all branches 412 and return, so as to pass through the second water pipe group unimpeded. The water flow is accelerated due to the flow pressure, making the forward flow easy and rapid, thereby realizing the rapid heat exchange of the inner wall of the insulation block 2 to cool the patient in the second water pipe group, and improving the cooling efficiency of the cooling device.

[0057] Embodiment 5:

[0058] As attached Figure 2 As shown: The difference from the above embodiment is that a plurality of cooling fins 403 are welded at equal intervals at the intersection of the straight tube 411 and the branch tube 412 on the outer side wall of the insulation block 2.

[0059] The specific implementation process is as follows: when the water flow that completes heat exchange with the patient's skin passes through several interconnected straight tubes 411 on the outer side wall of the insulation block 2, it will flow back at the intersection to slow down the flow rate. Therefore, all water flows will pass through the intersection of the straight tube 411 and the branch pipe 412. By setting the cooling plate 403 at the intersection of the straight tube 411 and the branch pipe 412, and respectively setting it at the front, middle and rear of the outer channel of the water flow, the control of the cooling plate 403 on the water flow temperature is improved, and the problem of temperature difficulty in control due to heat exchange between air temperature and water flow is reduced.

[0060] Embodiment 6:

[0061] As attached Figure 1 , Figure 2 and Figure 3As shown: The difference from the above embodiment is that the strap assembly includes a strap 701, the strap 701 is made of elastic material, and a rope buckle 702 for adjusting the length of the strap 701 is provided on the strap 701.

[0062] The specific implementation process is as follows: in the patient cooling preparation stage, the left and right side straps 701 are tightened by the rope buckle 702, and the length of the strap 701 is adjusted by the adjustable function of the rope buckle 702, so that the device can adapt to patients of different body shapes for cooling operations, reducing the probability of a decrease in cooling effect due to the insulation block 2 not fitting the patient.

[0063] Embodiment 7:

[0064] As attached Figure 1 As shown, the difference from the above embodiment is that the control unit includes a shell 801, and a side wall of one side of the shell 801 is fixedly connected with a heating button 803, a cooling button 804 and a display screen 802 for displaying the patient's body temperature and the target temperature, and the input end of the display screen 802 is electrically connected to a control board, and the heating button 803 and the cooling button 804 are both electrically connected to the control board.

[0065] The specific implementation process is as follows: During the cooling process, the temperature sensor 6 will transmit the collected temperature data to the intelligent system, and the intelligent system will transmit the temperature data to the display screen 802 in real time for display. The display screen 802 will also display the patient's target cooling temperature. The doctor can adjust the patient's target cooling temperature by observing the patient's real-time temperature, thereby reducing the probability of secondary injury to the patient due to continuous temperature drop. In addition, the medical staff compares the real-time body temperature with the patient's historical body temperature to analyze the patient's cooling situation, and transmits the signal of needing to increase the temperature to the intelligent system by pressing the heating button 803, and transmits the signal of needing to cool down to the intelligent system by pressing the cooling button 804. The intelligent system controls the refrigeration plate 403 to increase and decrease the temperature, thereby realizing the self-service of the device, making the operation more convenient, and improving the protection of the patient.

[0066] Embodiment 8:

[0067] The difference from the above embodiment is that the intelligent system includes a collection module, a processing module, a driving module and a display module.

[0068] The acquisition module is used to receive the temperature signal acquired by the temperature sensor 6 in real time, and then transmit the temperature signal to the processing module.

[0069] The processing module is used to convert the collected temperature signals into temperature data, transmit multiple real-time temperature data to the display module, and perform temperature data comparison processing at the same time, compare the patient's initial body temperature with the current body temperature, comprehensively analyze the current patient's cooling situation, determine whether the temperature of the cooling plate 403 needs to be increased or decreased, and then transmit the signal that the temperature needs to be increased or decreased to the driving module.

[0070] The display module is used to receive multiple temperature data from the processing module, transmit the received temperature data to the input end of the display screen 802, and present the patient's real-time body temperature through the output end of the display screen 802, so that medical staff can compare and analyze the patient's cooling condition by comparing the real-time temperature data with the historical temperature data to determine whether it is necessary to press the temperature increase button 803 or the temperature decrease button 804.

[0071] The driving module is used to receive signals from the heating button 803, the cooling button 804 and the processing module, control the power of the refrigeration plate 403, and realize temperature control of the water flow in the curved pipe 411. The device has a cooling safety threshold implemented by the processing module, and the medical staff presses the heating button 803 or the cooling button 804 to control the patient's cooling temperature, thereby reducing the probability of harm to the patient due to excessive cooling.
