Description

Technical Field

[0001] The present invention relates to the field of cardiac surgery nursing, and more particularly to a temperature control device for cardiac surgery nursing. Background Art

[0002] Cardiac surgery is the younger of the two branches of surgery. It mainly uses surgery to treat heart disease, such as heart bypass surgery, congenital heart disease surgery, and valve replacement. In order to reduce oxygen consumption and enhance the tolerance of tissue cells of some important organs to hypoxia, it is necessary to lower body temperature during surgery to reduce the metabolic activity of organs and tissues throughout the body, thereby meeting the need for temporary blockage of blood circulation during cardiac and major vascular surgery, and then rewarming is required after surgery.

[0003] Existing temperature control methods mostly involve cooling the patient naturally after general anesthesia or using an ice pillow to cool the patient's body. This method has a slow cooling speed, requires a long time for the patient to be under general anesthesia, and causes great harm to the patient's body. Long-term use of an ice pillow can easily cause frostbite on the patient's neck, which cannot meet the needs of modern medicine. When warming up after surgery, wrapping the patient in a quilt is often used, and the air is not circulated, and the surgical wound is prone to infection and ulceration. In addition, due to the lack of a body temperature maintenance device during the operation, the patient's body temperature often rises urgently during the operation, resulting in interruption and failure of the operation. Some new temperature control devices use the principle of air conditioning for temperature control, and the temperature control is not accurate.

[0004] In response to the above-mentioned problems, some solutions have been proposed in the prior art. For example, Chinese invention patent publication number CN112603639B discloses a temperature control device for cardiac surgery nursing. The device controls the pressure in the hot and cold water tanks by rotating the rotating drums with a rotating rod. Utilizing the principle of leverage, the human body can be easily lifted above the grid slot, which is labor-saving and convenient to operate with low noise. The first outer bladder, the first inner bladder, the second outer bladder, and the second inner bladder, made of soft materials, can be flattened by the human body to increase the contact area, resulting in rapid cooling and heating speeds, comfortable and gentle use, no harm to the patient's skin, high hygiene level, and low infection resistance. The patient's body temperature can be accurately controlled by adjusting the proportion of the second inner bladder in the second outer bladder. The patient's body temperature can be kept within an appropriate range during long operations with precise control. However, in actual use, the prior art requires the user to manually add hot and cold water. Manual addition makes it difficult to control the temperature, which easily leads to inaccurate temperature control. In addition, due to the long operation time, the water temperature will conduct heat to the outside world, causing the water temperature to gradually approach the room temperature, thereby seriously affecting the temperature control effect.

[0014] Furthermore, a sealing gasket is installed on the collecting tank, the sealing gasket is provided with a cavity, and a second air tube communicating with the elastic airbag is inserted into the cavity.

[0017] Furthermore, a silicone cushion is fixedly mounted on the top wall of the mattress.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] (1) This solution sets up a first water pipe and a second water pipe, and an air pump drives the water flow to circulate through the first water pipe, the temperature control chamber, and the second water pipe insulation box, so that the temperature of the temperature control chamber is always at the set value. At the same time, the setting of the filter can filter impurities in the water flow, thereby preventing impurities from adhering to the temperature control chamber and affecting the temperature control effect, thereby improving the temperature control effect;

[0021] (3) This solution sets an impeller, which drives the impeller to rotate when the water flows through it. The rotating impeller can then break up the water flow, so that the water flow in the insulation box is evenly mixed, thereby improving the temperature control effect. In addition, during the rotation of the impeller, the scraper can be driven to rotate through the rotating rod and the mounting ring, and the stains on the surface of the filter can be cleaned, thereby avoiding a large amount of impurities accumulating on the surface of the filter, resulting in the water flow being unable to pass through the filter normally into the insulation box and affecting the temperature control effect, thereby further improving the temperature control effect.

[0038] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0039] See also Figures 1 to 8 , a temperature control device for cardiac surgery nursing, comprising a bed 1, on which a temperature control component 2 is provided;

[0040] The temperature control component 2 is installed on the mattress 201 on the bed body 1, and a temperature control cavity 202 is opened on the mattress 201. An insulation box 203 is fixedly installed on the bottom wall of the bed body 1, and the insulation box 203 is filled with water. A controller 204 is provided on the side wall of the bed body 1. A heating pipe 205 electrically connected to the controller 204 is installed in the insulation box 203, and a refrigeration pipe 206 electrically connected to the controller 204 is installed in the insulation box 203. A pump body 207 is fixedly installed on the side wall of the incubator 203, and the input end of the pump body 207 is connected to the incubator 203. A first water pipe 208 connected to the temperature control cavity 202 is fixedly installed on the output end of the pump body 207. A second water pipe 209 connected to the temperature control cavity 202 is inserted on the side wall of the incubator 203 away from the pump body 207. A temperature sensor 210 electrically connected to the controller 204 is fixedly installed on the side wall of the incubator 203.

[0041] During use, the user can first set the desired temperature through the controller 204, and let the controller 204 adjust the water temperature in the incubator 203 through the cooling pipe 206 and the heating pipe 205. Then the user can use the pump body 207 to draw water from the incubator 203 and transport the water through the first water pipe 208 to the temperature control chamber 202. Then the patient can lie on the top wall of the mattress 201. At this time, the water in the temperature control chamber 202 can regulate the patient's body temperature. At the same time, after the water flows to the incubator 203 through the first water pipe 208, the water in the temperature control chamber 202 flows back to the incubator 203 through the second water pipe 209. At this time, the temperature sensor 210 will transmit the water temperature in the incubator 203 to the controller 204. Then the controller 204 can adjust the water temperature in the incubator 203 through the cooling pipe 206 and the heating pipe 205, so that the water temperature in the incubator 203 is always maintained at the set temperature, thereby improving the temperature control effect.

[0042] like Figure 2 、 Figure 4 、 Figure 8As shown, a filter chamber 301 is provided on the heat preservation box 203, and the end of the second water pipe 209 away from the temperature control chamber 202 is connected to the filter chamber 301, and a water inlet groove connected to the heat preservation box 203 is provided on the side wall of the filter chamber 301, and a filter screen 302 is provided in the filter chamber 301, and a vertical rod 303 is fixedly installed on the inner wall of the heat preservation box 203, and a rotating rod 304 is rotatably installed on the vertical rod 303, and an impeller 305 is fixedly installed on the rotating rod 304, and a scraper 306 is provided on the rotating rod 304, and a linkage component 4 cooperating with the scraper 306 is provided in the filter chamber 301.

[0043] The linkage assembly 4 includes a push block 401 fixedly mounted on the side wall of the filter chamber 301, and the end of the push block 401 close to the scraper 306 is an inclined surface, a first spring 402 is installed between the filter chamber 301 and the filter screen 302, a mounting ring 403 is rotatably mounted on the side wall of the filter chamber 301, a sliding groove 404 is provided on the rotating rod 304, and the scraper 306 is fixedly mounted on the mounting ring 403.

[0044] An air cavity 405 is provided on the mattress 201, and air holes 406 are evenly provided on the top wall of the air cavity 405. A telescopic tube 407 is installed between the filter cavity 301 and the filter screen 302. An air inlet valve 408 whose input end is connected to the outside is inserted into the filter cavity 301. An exhaust valve 409 is inserted into the filter cavity 301. A first air pipe 410 connected to the air cavity 405 is fixedly installed on the output end of the exhaust valve 409.

[0045] By adopting the above technical solution, since scale will be generated after the water flow is repeatedly heated, if the scale cannot be cleaned in time, a large amount of scale will adhere to the inner wall of the temperature control chamber 202, which will seriously affect the temperature control effect. Then, after the water flows through the second water pipe 209, the water flows through the filter chamber 301 and the water inlet trough into the insulation box 203, and in the process of the water flow passing through the filter chamber 301, the filter 302 can filter the impurities in the water flow, thereby preventing a large amount of scale from adhering to the temperature control chamber 202 and affecting the temperature control effect, and in the process of the water flow passing through the water inlet trough, it will hit the impeller 305 and drive The impeller 305 rotates, and then the rotating impeller 305 can break up the water flow, so that the water flow in the insulation box 203 is evenly mixed, thereby improving the temperature control effect, and in the process of the impeller 305 rotating, the scraper 306 is driven to rotate through the rotating rod 304. In the process of the scraper 306 rotating, the stains on the surface of the filter 302 can be driven to rotate, and the stains are moved to the edge of the filter 302 under the action of centrifugal force, thereby avoiding a large amount of impurities from accumulating on the surface of the filter 302, resulting in the water flow being unable to normally pass through the filter 302 into the insulation box 203, affecting the temperature control effect, and further improving the temperature control effect.

[0046] When the filter 302 is in the state of being moved, the filter 302 is moved and the filter 302 is moved back to the state in which it is moved.

[0047] When the filter screen 302 drives the first spring 402 to expand and contract, the filter screen 302 also drives the telescopic tube 407 to expand and contract synchronously, and the first spring 402 can always be protected during the expansion and contraction of the telescopic tube 407 to prevent the first spring 402 from being corroded. Then, during the expansion of the telescopic tube 407, air is sucked in from the outside through the air inlet valve 408, and during the contraction of the telescopic tube 407, the air flow is driven to flow into the air cavity 405 through the exhaust valve 409 and the first air pipe 410, and then to the outside through the air hole 406 on the air cavity 405. Due to the long operation time, the patient lies on the mattress 201 for a long time, which will cause the patient to fit the mattress 201. Long-term airtightness affects the patient's comfort. By providing the air holes 406, the air permeability of the joint between the patient and the mattress 201 can be improved, and by transmitting air flow into the air cavity 405, the air flow rate in the air cavity 405 can be accelerated, thereby improving the cleaning effect of the filter 302 while improving the patient's comfort. In the process of air flow passing through the air cavity 405 and the air holes 406 to the outside world, the temperature in the temperature control cavity 202 will first be transmitted to the air cavity 405, and then in the process of air flow passing through the air holes 406 on the air cavity 405 to the outside world, the temperature around the patient's body can be regulated, thereby further improving the temperature control effect.

[0048] like Figure 2 、 Figure 3 、 Figure 6As shown, a collecting box 501 is fixedly installed on the bottom wall of the heat preservation box 203, and a collecting groove connected to the filter chamber 301 is opened on the top wall of the collecting box 501. A baffle 502 is hinged in the collecting groove, and a spring 503 is installed between the baffle 502 and the collecting groove. A first magnet 504 is embedded in the baffle 502, and a second magnet 505 is embedded in the scraper 306, and the first magnet 504 and the second magnet 505 repel each other.

[0049] A sewage pipe 601 is inserted into the side wall of the collecting box 501, and a groove is opened on the side wall of the collecting box 501. A push plate 602 is slidably installed in the groove, and a sealing plate 603 fixedly connected to the push plate 602 is slidably installed on the inner wall of the collecting box 501. An elastic airbag 604 is jointly installed between the top wall of the sealing plate 603 and the collecting box 501.

[0050] A sealing gasket 605 is installed on the collecting tank. The sealing gasket 605 defines a cavity 606 . A second air pipe 607 communicating with the elastic airbag 604 is inserted into the cavity 606 .

[0051] By adopting the above technical solution, the second magnet 505 is driven to rotate during the rotation of the scraper 306, and when the second magnet 505 rotates to the lowest point, the distance between the second magnet 505 and the first magnet 504 reaches the minimum. At this time, the repulsive force between the first magnet 504 and the second magnet 505 reaches the maximum. Then, under the action of the repulsive force between the first magnet 504 and the second magnet 505, the first magnet 504 drives the baffle 502 to rotate. At this time, the spring 503 starts to accumulate power. Then, when the baffle 502 is out of contact with the collection tank, the impurities enter the collection box 501 through the collection tank under the action of centrifugal force. Then, when the scraper 306 drives the second magnet 505 away from the first magnet 504, the spring 503 starts to extend and drives the baffle 502 to reset. During the process of the baffle 502 resetting, the collection tank is blocked again, thereby preventing impurities from adhering to the surface of the filter 302 again and affecting the temperature control effect, thereby further improving the temperature control effect.

[0052] When the temperature control device is not in use, the user can regularly check the collection box 501. When there are too many stains in the collection box 501, the user can first push the push plate 602 to move upward, and in the process of the push plate 602 moving upward, the sealing plate 603 is driven to move upward. At this time, the elastic airbag 604 is compressed and has a tendency to recover. In the process of the sealing plate 603 moving upward, it gradually loses contact with the drain pipe 601. At this time, the stains in the collection box 501 flow to the outside through the drain pipe 601, thereby avoiding the stains in the collection box 501 from affecting the normal flow of stains in the filter cavity 301 into the collection box 501, resulting in a worse temperature control effect, thereby further improving the temperature control effect.

[0053] In the process of the elastic air bag 604 being compressed, the airflow in the elastic air bag 604 flows to the cavity 606 on the sealing pad 605 through the second air pipe 607, and the sealing pad 605 is inflated, and then the inflated sealing pad 605 can be tightly attached to the baffle 502, thereby improving the sealing performance of the baffle 502 on the collecting groove, preventing the water flow in the incubator 203 from flowing to the outside, causing the water flow in the incubator 203 to be insufficient to affect the temperature control effect, and further improving the temperature control effect.

[0054] Then when the stain cleaning in the collecting box 501 is completed, the elastic air bag 604 is stretched and drives the sealing plate 603 to seal the drain pipe 601 again, and in the process of the elastic air bag 604 being stretched, the elastic air bag 604 inhales air from the cavity 606 through the second air pipe 607, and the sealing pad 605 is retracted, thereby avoiding the influence of the inflated sealing pad 605 on the normal rotation of the baffle 502.

[0055] As shown in Figure 2 The side wall of the incubator 203 is provided with a water adding groove, and a plug plate 7 is detachably installed in the water adding groove.

[0056] By adopting the above technical scheme, when water needs to be added to the incubator 203, the user can first close the controller 204 and remove the plug plate 7, then pour water into the incubator 203, and then seal the water adding groove with the plug plate 7 when the water adding is completed, thereby facilitating water adding.

[0057] As shown in Figure 1 The side wall of the collecting box 501 is provided with an observation port, the observation port is provided with a glass sheet 8 made of transparent material, and the bottom wall of the collecting box 501 is inclined.

[0058] By adopting the above technical scheme, the user can observe the stain storage amount in the collecting box 501 through the glass sheet 8, thereby facilitating the user to clean the collecting box 501 in time, and by making the bottom wall of the collecting box 501 inclined, the stains in the collecting box 501 can flow to the outside through the drain pipe 601.

[0059] As shown in Figure 5 The top wall of the mattress 201 is fixedly provided with a silica gel soft pad 9.

[0060] By adopting the above technical scheme, when the user lies on the mattress 201, the silica gel soft pad 9 will deform and tightly attach to the patient, thereby further improving the comfort of the patient.

[0061] Instructions for use: When in use, the user can first set the desired temperature through the controller 204, and make the controller 204 adjust the water temperature in the incubator 203 through the cooling pipe 206 and the heating pipe 205. Then the user can draw the water flow in the incubator 203 through the pump body 207, and transport the water flow to the temperature control chamber 202 through the first water pipe 208. Then the patient can lie on the top wall of the mattress 201. At this time, the water flow in the temperature control chamber 202 can regulate the patient's body temperature. At the same time, after the water flows to the incubator 203 through the first water pipe 208, the water in the temperature control chamber 202 is cooled. The water flows back into the insulation box 203 through the second water pipe 209. At this time, the temperature sensor 210 will transmit the water temperature in the insulation box 203 to the controller 204, and then the controller 204 can adjust the water temperature in the insulation box 203 through the cooling pipe 206 and the heating pipe 205, so that the water temperature in the insulation box 203 is always maintained at the set temperature; in the process of the water flowing through the water inlet trough, it will hit the impeller 305 and drive the impeller 305 to rotate, and then the rotating impeller 305 can break up the water flow, so that the water flow in the insulation box 203 is evenly mixed, thereby improving the temperature control effect, and During the rotation of the impeller 305, the scraper 306 is driven to rotate through the rotating rod 304. During the rotation of the scraper 306, the dirt on the surface of the filter 302 can be driven to rotate, and the dirt is moved to the edge of the filter 302 under the action of centrifugal force, thereby preventing a large amount of impurities from accumulating on the surface of the filter 302; during the rotation of the rotating rod 304, the scraper 306 is driven to rotate through the sliding groove 404 and the mounting ring 403, and then during the rotation of the scraper 306, it gradually contacts the inclined surface of the push block 401, and then the inclined surface of the push plate 602 applies a thrust to the scraper 306, and then under the action of the thrust, the scraper The mounting ring 403 is driven by the support 406 to slide along the sliding groove 404. During the sliding process of the mounting ring 403 along the sliding groove 404, the filter 302 is driven to move and squeeze the first spring 402. Then, when the push block 401 is out of contact with the scraper 306, the first spring 402 stretches and passes through the filter 302 and the mounting ring 403 to drive the scraper 306 to reset. That is, during the rotation of the scraper 306, the filter 302 is driven to shake. During the shaking process of the filter 302, impurities on the surface of the filter 302 are loosened, thereby facilitating the scraper 306 to clean the impurities on the surface of the filter 302.When the filter screen 302 drives the first spring 402 to expand and contract, the filter screen 302 also drives the telescopic tube 407 to expand and contract synchronously, and the first spring 402 can always be protected during the expansion and contraction of the telescopic tube 407 to prevent the first spring 402 from being corroded. Then, during the expansion of the telescopic tube 407, air is sucked from the outside through the air inlet valve 408, and during the contraction of the telescopic tube 407, the air flow is driven to flow through the exhaust valve 409 and the first air pipe 410 into the air cavity 405, and then to the outside through the air hole 406 on the air cavity 405. The air holes 406 can improve the air permeability of the joint between the patient and the mattress 201, and the air flow rate in the air cavity 405 can be accelerated by transmitting air into the air cavity 405, thereby improving the cleaning effect of the filter 302 and improving the comfort of the patient. In the process of the air flow passing through the air cavity 405 and the air holes 406 to the outside, the temperature in the temperature control cavity 202 will first be transferred to the air cavity 405, and then the air will pass through the air holes 406 on the air cavity 405. 406 flows to the outside world, the temperature around the patient's body can be regulated; during the rotation of the scraper 306, the second magnet 505 is driven to rotate, and when the second magnet 505 rotates to the lowest point, the distance between the second magnet 505 and the first magnet 504 reaches the minimum, and at this time the repulsive force between the first magnet 504 and the second magnet 505 reaches the maximum, and then under the action of the repulsive force between the first magnet 504 and the second magnet 505, the first magnet 504 drives the baffle 502 to rotate, and at this time the spring 503 starts to accumulate power, and then when the baffle 502 is out of contact with the collection tank Finally, the impurities enter the collection box 501 through the collection groove under the action of centrifugal force. When the temperature control device is not in use, the user can regularly check the collection box 501. If there is too much dirt in the collection box 501, the user can first push the push plate 602 upward. As the push plate 602 moves upward, it drives the sealing plate 603 upward. At this time, the elastic airbag 604 is compressed and has a tendency to recover. As the sealing plate 603 moves upward, it gradually loses contact with the drainage pipe 601. At this time, the dirt in the collection box 501 flows to the outside through the drainage pipe 601.
