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 treats heart disease through surgery, such as heart bypass surgery, congenital heart disease surgery, valve replacement, etc. In order to reduce oxygen consumption and enhance the tolerance of tissue cells of some important organs to hypoxia, it is necessary to lower the body temperature during surgery to reduce the metabolic activity of organs and tissues throughout the body, thereby meeting the need for temporary blocking of blood circulation during heart and large blood vessel surgery, and then rewarming is required after surgery.

[0003] Most of the existing temperature control methods are to cool down the patient naturally after general anesthesia or use an ice pillow to cool the patient's body. This method has a slow cooling speed, and the patient needs a long time for general anesthesia, which is very harmful 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, a quilt is often used, and the air is not circulated. 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 view of the above problems, some solutions are also provided in the prior art. For example, the Chinese invention patent with the announcement number CN112603639B discloses a temperature control device for cardiac surgery nursing. The device can control the pressure in the hot water cylinder and the cold water cylinder by rotating the rotating cylinder through a rotating rod. The lever principle can be used to easily lift the human body above the grid slot. The operation is labor-saving and convenient, and the noise is low. The first outer skin bag, the first inner skin bag, the second outer skin bag and the second inner water bag made of soft materials can be flattened by the human body to increase the contact area, and the cooling and heating speed is fast. The use is comfortable and gentle, will not hurt the patient's skin, has a high sanitation level, and is not easy to be infected. The patient's body temperature can be accurately controlled by adjusting the proportion of the second inner water bag in the second outer skin bag, and the patient's body temperature can be kept within a suitable range during a long operation, and the control is accurate; however, in actual use of the prior art, the user needs to manually add hot water and cold water, and it is difficult to control the temperature by manual addition, which easily makes the temperature control inaccurate, and due to the long operation time, the water temperature will be heat-conducted with the outside world, causing the water temperature to gradually approach the indoor temperature, thereby seriously affecting the temperature control effect.

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

[0019] (1) In this solution, the first water pipe and the second water pipe are arranged to cooperate, and the 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.

[0020] (2) This solution provides a push block, which can drive the filter to shake during the rotation of the scraper, so that the scraper can clean the filter. At the same time, the filter shakes and drives the telescopic tube to extend and retract. The telescopic tube can drive the airflow into the air cavity during the extension and retraction process, thereby accelerating the air flow rate in the air cavity and improving the patient's comfort. At the same time, when the airflow flows to the outside through the air hole, it can also accelerate the exchange of water temperature and the temperature around the patient, so that the temperature around the patient's body can be regulated, further improving the temperature control effect.

[0021] (3) This solution sets an impeller, which drives the impeller to rotate when water flows through it. The rotating impeller can then break up the water flow, thereby evenly mixing the water flow in the insulated box and improving the temperature control effect. In the process of the impeller rotating, 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 from accumulating on the surface of the filter, resulting in the inability of water to pass through the filter normally into the insulated 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, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention 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 body 1, on which a temperature control component 2 is provided;

[0040] The temperature control component 2 is installed on a mattress 201 on the bed body 1, and a temperature control cavity 202 is opened on the mattress 201. A heat preservation box 203 is fixedly installed on the bottom wall of the bed body 1, and the heat preservation 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 heat preservation box 203. A refrigeration pipe 206 electrically connected to the controller 204 is installed in the heat preservation 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 chamber 202 is fixedly installed on the output end of the pump body 207, a second water pipe 209 connected to the temperature control chamber 202 is inserted on the side wall of the incubator 203 away from the pump body 207, and 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 required 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, and then the user can extract 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, and 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 flow flows to the incubator 203 through the first water pipe 208, the water flow 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, and 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, which plays a role in 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 one end of the second water pipe 209 away from the temperature control chamber 202 is connected to the filter chamber 301, a water inlet groove connected to the heat preservation box 203 is opened on the side wall of the filter chamber 301, a filter screen 302 is provided in the filter chamber 301, a vertical rod 303 is fixedly installed on the inner wall of the heat preservation box 203, a rotating rod 304 is rotatably installed on the vertical rod 303, an impeller 305 is fixedly installed on the rotating rod 304, 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 in the filter cavity 301. An exhaust valve 409 is inserted in the filter cavity 301, and 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 flow passes through the second water pipe 209, the water flow will pass through the filter chamber 301 and the water inlet tank into the heat preservation box 203, and the filter screen 302 can filter impurities in the water flow during the process of the water flow passing through the filter chamber 301, thereby preventing a large amount of scale from adhering to the temperature control chamber 202 and affecting the temperature control effect, and the water flow will hit the impeller 305 during the process of passing through the water inlet tank, 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. In the process of rotation of the impeller 305, the scraper 306 is driven to rotate through the rotating rod 304. In the process of rotation of the scraper 306, 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 inability of the water flow to enter the insulation box 203 normally through the filter 302, affecting the temperature control effect, thereby further improving the temperature control effect.

[0046] The scraper 306 is driven to rotate through the slide groove 404 and the mounting ring 403 during the rotation of the rotating rod 304, and then gradually contacts the inclined surface of the pushing block 401 during the rotation of the scraper 306, and then the inclined surface of the pushing plate 602 applies a thrust to the scraper 306, and then the scraper 306 drives the mounting ring 403 to slide along the slide groove 404 under the action of the thrust, and the filter 302 is driven to move and squeeze the first spring 402 during the sliding of the mounting ring 403 along the slide groove 404, and then when the pushing block 401 is out of contact with the scraper 306, the first spring 402 stretches and drives the scraper 306 to reset through the filter 302 and the mounting ring 403, that is, the filter 302 can be driven to shake during the rotation of the scraper 306, and the impurities on the surface of the filter 302 can be loosened during the shaking of the filter 302, so that it is convenient for the scraper 306 to clean the impurities on the surface of the filter 302, thereby improving the cleaning effect of the filter 302.

[0047] When the filter screen 302 drives the first spring 402 to expand and contract, the filter screen 302 also drives the expansion tube 407 to expand and contract synchronously, and the first spring 402 can be always protected during the expansion and contraction of the expansion tube 407 to prevent the first spring 402 from being corroded, and then the expansion tube 407 is stretched to inhale air from the outside through the air inlet valve 408, and the expansion tube 407 is contracted to drive the air flow through the exhaust valve 409 and the first air pipe 410 to flow into the air cavity 405, and then flow 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 opening the air hole 406, the air permeability of the joint between the patient and the mattress 201 can be improved, and by conveying air flow in 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 and improving the patient's comfort. In the process of the air flow passing through the air cavity 405 and the air hole 406 to the outside, the temperature in the temperature control cavity 202 will be first transmitted to the air cavity 405, and then in the process of the air flow passing through the air hole 406 on the air cavity 405 to the outside, 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, 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, a spring 503 is installed between the baffle 502 and the collecting groove, a first magnet 504 is embedded in the baffle 502, 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, a groove is opened on the side wall of the collecting box 501, a push plate 602 is slidably installed in the groove, a sealing plate 603 fixedly connected to the push plate 602 is slidably installed on the inner wall of the collecting box 501, and 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 is provided with 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 which 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, at which time the spring 503 begins to accumulate force, and then when the baffle 502 is out of contact with the collecting tank, the impurities enter the collecting box 501 through the collecting tank under the action of centrifugal force, and then when the scraper 306 drives the second magnet 505 away from the first magnet 504, the spring 503 begins to stretch and drives the baffle 502 to reset, and the collecting tank is blocked again during the resetting of the baffle 502, thereby preventing impurities from adhering to the surface of the filter screen 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 drive the sealing plate 603 to move upward during the upward movement of the push plate 602. At this time, the elastic airbag 604 is compressed and has a tendency to recover. During the upward movement of the sealing plate 603, 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 the stains in the filter chamber 301 into the collection box 501, resulting in a poor temperature control effect, thereby further improving the temperature control effect.

[0053] During the compression of the elastic airbag 604, the airflow in the elastic airbag 604 flows into the cavity 606 on the sealing gasket 605 through the second air pipe 607, causing the sealing gasket 605 to expand. The expanded sealing gasket 605 can then fit tightly with the baffle 502, thereby improving the sealing performance of the baffle 502 to the collection tank, preventing the water in the insulation box 203 from flowing to the outside, resulting in too little water in the insulation box 203 affecting the temperature control effect, thereby further improving the temperature control effect.

[0054] Then, when the stains in the collection box 501 are cleaned, the elastic airbag 604 stretches and drives the sealing plate 603 to seal the sewage pipe 601 again. During the stretching process of the elastic airbag 604, the elastic airbag 604 absorbs air from the cavity 606 through the second air pipe 607, and causes the sealing gasket 605 to shrink and reset, thereby preventing the expanded sealing gasket 605 from affecting the normal rotation of the baffle 502.

[0055] like Figure 2 As shown, a water adding groove is provided on the side wall of the heat preservation box 203, and a plug plate 7 is detachably installed in the water adding groove.

[0056] By adopting the above technical solution, when water needs to be added to the insulation box 203, the user can first turn off the controller 204 and remove the plug plate 7, and then pour the water into the insulation box 203. When the water is added, the water adding tank is sealed again by the plug plate 7, which makes it easier to add water.

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

[0058] By adopting the above technical solution, the user can observe the amount of stains stored in the collection box 501 through the glass sheet 8, so that the user can clean the collection box 501 in time, and by making the bottom wall of the collection box 501 an inclined surface, the stains in the collection box 501 can flow to the outside through the sewage pipe 601.

[0059] like Figure 5 As shown, a silicone cushion 9 is fixedly mounted on the top wall of the mattress 201 .

[0060] By adopting the above technical solution, when the user lies on the mattress 201, the silicone cushion 9 will be deformed and fit tightly to the patient, thereby further improving the patient's comfort.

[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 temperature in the temperature control chamber 202 The water flows back into the insulated box 203 through the second water pipe 209. At this time, the temperature sensor 210 transmits the water temperature in the insulated box 203 to the controller 204, and then the controller 204 can adjust the water temperature in the insulated box 203 through the refrigeration pipe 206 and the heating pipe 205, so that the water temperature in the insulated box 203 is always maintained at the set temperature; when the water flows through the water inlet tank, 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 insulated 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 slide 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 first spring 402 is pressed against the first spring 402 and the second spring 403 is pressed against the first spring 402. ...When the filter screen 302 drives the first spring 402 to expand and contract, the filter screen 302 also drives the expansion tube 407 to expand and contract synchronously, and the first spring 402 can be protected all the time during the expansion and contraction of the expansion tube 407 to prevent the first spring 402 from being corroded, and then the expansion tube 407 is stretched and air is sucked from the outside through the air inlet valve 408, and the expansion tube 407 is contracted and drives the air flow to flow into the air cavity 405 through the exhaust valve 409 and the first air pipe 410, and then flows to the outside through the air hole 406 on the air cavity 405. The air hole 406 is provided on the mattress 201, which will cause the patient and the mattress 201 to be airtight for a long time, affecting the patient's comfort. By opening the air hole 406, the air permeability of the patient and the mattress 201 can be improved, and by transmitting airflow in 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 and improving the patient's comfort. In the process of the air flow passing through the air cavity 405 and the air hole 406 to the outside, the temperature in the temperature control cavity 202 will be first transmitted to the air cavity 405, and then the air will pass through the air cavity 405. The air hole 406 is used to transfer the air to the air cavity 405. 406 flows to the outside, 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, 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, at this time the spring 503 starts to accumulate power, and then when the baffle 502 is out of contact with the collecting tank Afterwards, the impurities enter the collection box 501 through the collection slot under the action of centrifugal force; when the temperature control device is not used, 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 the sealing plate 603 moves upward during the upward movement of the push plate 602. At this time, the elastic airbag 604 is compressed and has a tendency to recover. During the upward movement of the sealing plate 603, it gradually breaks away from the sewage pipe 601. At this time, the stains in the collection box 501 flow to the outside through the sewage pipe 601. ;
