Description

Technical Field

[0001] This invention relates to the field of medical device technology, and more particularly to a cardiovascular angiography care device. Background Technology

[0002] Cardiovascular angiography is a technique that uses contrast agents to visualize the cardiovascular system. This radiographic technique is used in cardiac catheterization to identify any heart chamber, major blood vessel, or coronary artery. It involves rapidly injecting a contrast agent containing organic compounds, transparent under X-ray irradiation, into the bloodstream, allowing the heart and major blood vessel cavities to be visualized under X-ray. Simultaneously, rapid radiography, video recording, or other methods can be used to capture the visualization process. The results show the flow sequence of the contrast agent-containing blood and the filling status of the heart and major blood vessels, thus revealing physiological and anatomical changes in the heart and major blood vessels. It is a valuable method for diagnosing cardiovascular diseases. It utilizes a cardiac catheter to directly and rapidly inject the contrast agent into selected heart chambers or major blood vessels, quickly achieving maximum concentration and obtaining excellent visualization, clearly showing lesions in that area. It has become one of the commonly used diagnostic methods for cardiovascular diseases, especially essential for the preoperative diagnosis of complex cardiovascular malformations or coronary artery bypass grafting.

[0003] Postoperative care after cardiovascular angiography includes wound hemostasis, vital sign monitoring, and contrast agent excretion. Wound hemostasis is generally achieved through pressure hemostasis. Existing technologies disclose a number of pressure hemostasis devices that can precisely adjust the pressure position and pressure force, thereby ensuring stable and safe hemostasis at the wound site. Vital signs monitoring, including heart rate, blood pressure, and respiration, will be conducted using the hospital's existing equipment. Contrast agent excretion is mainly through the kidneys, and can be achieved through hydration and diuresis via drinking water or injections.

[0004] At present, there is no dedicated cardiovascular angiography care device. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a cardiovascular angiography nursing device that facilitates postoperative care throughout the entire process.

[0006] The present invention is achieved through the following technical solution: a cardiovascular angiography nursing device, including a nursing bed, the nursing bed including a bed frame, a mobile platform for carrying patients provided above the bed frame, a positioning device one provided between the bed frame and the mobile platform, a multi-functional platform connected to the bed frame, a positioning device two provided between the multi-functional platform and the bed frame, the multi-functional platform including a pressure hemostasis device support base, a drinking water constant temperature chamber, an injection constant temperature chamber, a low temperature constant temperature chamber, and a urine collection chamber.

[0007] Furthermore, the mobile platform includes a rigid frame, with a handle at one end of the rigid frame, and a support platform connected to the rigid frame at the upper end of the bed frame. The support platform includes multiple support beams at the upper end of the bed frame, and the upper surface of the support beams is an upward-facing arc surface.

[0008] Furthermore, the positioning device includes a connecting frame disposed on one side of the bed frame. The connecting frame is disposed along the length direction of the bed frame. Multiple positioning holes are distributed on the connecting frame along the length direction. Multiple positioning holes are disposed on the moving platform corresponding to the positioning holes. The positioning holes are positioned by positioning pins.

[0009] Furthermore, the multifunctional platform includes a housing, in which the drinking water constant temperature chamber, injection constant temperature chamber, low temperature constant temperature chamber, and urination chamber are disposed. The support base for the pressure hemostasis device is disposed above the housing. The second positioning device includes a connecting plate disposed on the side of the support base for the pressure hemostasis device. The connecting plate is provided with a third positioning hole that mates with the first positioning hole. The first positioning hole and the third positioning hole are positioned by a second positioning pin.

[0010] Furthermore, the temperature of the drinking water constant temperature chamber is controlled at 40-45℃, the temperature of the injection constant temperature chamber is controlled at 25-30℃, and the temperature of the low temperature constant temperature chamber is controlled at 5-10℃.

[0011] Furthermore, the drinking water constant temperature chamber is connected to a temperature control device one, the injection constant temperature chamber is connected to a temperature control device two, and the low temperature constant temperature chamber is connected to a temperature control device three. The temperature control device one, temperature control device two, and temperature control device three all include a heat insulation layer.

[0012] Furthermore, the temperature control device one also includes a refrigerant coil one, the temperature control device two also includes a refrigerant coil two, and the temperature control device three also includes a refrigerant coil three. The refrigerant coil one, refrigerant coil two, and refrigerant coil three are connected to the compressor, the refrigerant tank, and the expansion valve. The refrigerant coil one, refrigerant coil two, and refrigerant coil three are connected to the compressor, the refrigerant tank, and the expansion valve through pipelines to form an air conditioning system.

[0013] Furthermore, the urination chamber is connected to an exhaust port, and a filter is installed at the exhaust port.

[0014] Furthermore, both the bed frame and the multi-functional platform are equipped with brake wheels.

[0015] Furthermore, it also includes a local cooling system, which includes a gas source connected to a heat-conducting pipe I that works with a low-temperature constant temperature chamber and a heat-conducting pipe II that works with an injection constant temperature chamber. The heat-conducting pipe I is connected to a main valve through a valve I, and the heat-conducting pipe II is connected to the main valve through a valve II. The main valve is connected to a nozzle, which acts on the wound.

[0016] The beneficial effects of this invention are as follows: 1. After the surgery, the patient is transferred to the nursing device for postoperative care. The mobile platform is placed on the operating table for the surgery. After the surgery, the patient is transferred to the nursing device via the mobile platform. The mobile platform is rigid, which can avoid changing the patient's position during the transfer, thereby avoiding postoperative bleeding. After being moved to the bed frame, the mobile platform is supported by the support platform. Since the upper end of the support beam is an upward arc surface, the friction between the support platform and the mobile platform is small, which facilitates the lateral adjustment of the position of the mobile platform. After the position is adjusted, the mobile platform is fixed to the bed frame by the positioning device for easy positioning. 2. The support base of the compression hemostasis device is supported by the box and positioned with the bed frame, thereby stabilizing the compression hemostasis device and eliminating the need for multiple patient transfers. After compression hemostasis is completed, the support base and the compression hemostasis device are removed. 3. The nursing bed is universal and can be used for different patients and surgeries. It can avoid changing the patient's position during the transfer. The items in the multi-functional platform are prepared separately according to the patient's condition, so as to facilitate use. Since the nursing bed is not equipped with guardrails, it should be moved slowly during use to avoid shaking the patient and the risk of tipping over. 4. By adjusting the air volume at valve one and valve two, the temperature of the air supplied to the main valve can be controlled. The temperature is controlled at 15-18℃. The main valve is connected to a nozzle. The air velocity is controlled by the main valve. The nozzle is a flexible hose. The outlet end of the nozzle is fixed to the human body with medical tape, so that the nozzle acts on the wound and slowly delivers low-temperature air to the vicinity of the wound to avoid local overheating.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1 like Figure 1-7As shown, a cardiovascular angiography nursing device includes a nursing bed, which includes a bed frame 1. A mobile platform for carrying the patient is detachably installed on the bed frame 1. A positioning device is located between the bed frame 1 and the mobile platform. In this embodiment, a brake wheel 7 is installed at the lower end of the bed frame 1. The mobile platform includes a rigid frame 2, with a handle 3 installed at the end of the rigid frame 2. The rigid frame 2 is made of carbon fiber material and is designed to withstand a load of 200 kg without deformation. A mattress is placed on the rigid frame 2. A support platform connected to the rigid frame 2 is installed at the upper end of the bed frame 1. The support platform includes multiple parallel transverse support beams 8 set at the upper end of the bed frame 1. The upper surface of the support beams 8 is an upward-facing arc surface. Specifically, the support beams 8 are made of steel pipes. The lower end of the support beams 8 is fixed to the bed frame 1 by bolts 17. The cardiovascular angiography surgery is performed on the operating table, and the patient is given general anesthesia. After the surgery, the patient is transferred to the nursing device for postoperative care. The mobile platform is placed on the operating table, and the patient is taken to the mobile platform after the surgery. The patient is transferred to the nursing device. The moving platform is rigid, which can prevent changes in the patient's position during the transfer, thereby avoiding postoperative bleeding. After being moved to the bed frame, the moving platform is supported by the support platform. Since the upper end face of the support beam 8 is an upward arc surface, the friction between the support platform and the moving platform is small, which facilitates the lateral adjustment of the moving platform's position. After the position is adjusted, the moving platform is fixed to the bed frame 1 by the positioning device 1. For easy positioning, the positioning device 1 includes a connecting frame 4 fixed to one side of the bed frame 1. The connecting frame 4 is fixed along the length direction of the bed frame 1. Multiple positioning holes 1 are distributed along the length direction on the connecting frame 4. Multiple positioning holes 2 are corresponding to the positioning holes 1 on the moving platform. The positioning holes 1 and positioning holes 2 are positioned by positioning pins 1 5. In this embodiment, the connecting frame 4 is a side-standing long strip plate, and the distance between two adjacent positioning holes is 30-40cm. During the test, it was found that stable fixation can be achieved with only 3-4 positioning pins 1 5, which is convenient for operation.

[0022] The bed frame 1 is connected to a multi-functional platform 6. A positioning device 2 is installed between the multi-functional platform 6 and the bed frame 1. The multi-functional platform 6 includes a pressure hemostasis device support 9, a drinking water temperature-controlled chamber 12, an injection temperature-controlled chamber 13, a low-temperature temperature-controlled chamber 14, and a urination chamber 16. Specifically, the multi-functional platform 6 includes a housing, with the drinking water temperature-controlled chamber 12, injection temperature-controlled chamber 13, low-temperature temperature-controlled chamber 14, and urination chamber 16 distributed inside the housing. The pressure hemostasis device support 9 is located on top of the housing. A brake wheel 7 is also installed at the lower end of the multi-functional platform 6. After platform 6 moves to the position of the nursing bed, the pressure hemostasis device support 9 is fixed to the bed frame 1 by positioning device two. Positioning device two includes a connecting plate 11 fixed to the side of the pressure hemostasis device support 9. The connecting plate 11 has a positioning hole three that matches the positioning hole one. Positioning hole one and positioning hole three are positioned by positioning pin two, fixing the pressure hemostasis device to the pressure hemostasis device support 9. The pressure hemostasis device support 9 is fixed to the bed frame 1 by positioning pin two. At the same time, the bed frame 1 is fixed to the moving platform. Finally, pressure hemostasis is achieved. The position between the device and the patient is fixed. The working head of the pressure hemostasis device is adjusted so that it cooperates with the wound to stop bleeding. In the prior art, physicians select from existing pressure hemostasis devices according to their needs. When a cantilever pressure hemostasis device is used, such as the "Intelligent Pressure Device for Cardiovascular Angiography" with application number "202111349133.6", a specially designed nursing bed is required to support and position the pressure components and adjustment device. The patient needs to be transferred multiple times, which is not conducive to postoperative care. In this embodiment, the pressure... The pressure hemostasis device support base 9 is supported by the box and positioned with the bed frame 1, thereby stabilizing the pressure hemostasis device and eliminating the need for multiple patient transfers. After pressure hemostasis is completed, the pressure hemostasis device support base 9 and the pressure hemostasis device are removed. To facilitate the positioning between the pressure hemostasis device support base 9 and the box, the lower end of the pressure hemostasis device support base 9 has a groove that matches the box, thereby stabilizing the pressure hemostasis device support base 9 and the pressure hemostasis device as they move with the box. A handle 2 10 is also installed on the side of the pressure hemostasis device support base 9 for easy movement.

[0023] The drinking water constant temperature chamber 12 controls the temperature at 40-45℃. The drinking water constant temperature chamber 12 is located at the top of the box, with an opening at the top for placing a water cup. Since patients need to drink a lot of water after surgery to achieve the effect of diuresis and excretion of contrast agent, it is difficult for a thermos cup to meet the water volume, so the drinking water constant temperature chamber 12 is introduced. The temperature of the injection solution constant temperature chamber 13 is controlled at 25-30℃. The best way for patients to replenish fluids and promote diuresis after surgery is to drink water. However, when patients are unable to move or are not fully awake, they can be given intravenous saline solution to promote diuresis. In some cases, diuretics are added to the saline solution. The saline solution to be injected is stored in the injection solution constant temperature chamber 13. The low-temperature constant temperature chamber 14 controls the temperature at 5-10℃. During the postoperative hemostasis and subsequent monitoring process, it is necessary to monitor the wound condition, such as bleeding and swelling. Local disinfection and cooling treatment is required, and ice packs and medical alcohol are stored in the low-temperature constant temperature chamber 14.

[0024] The drinking water constant temperature chamber 12 is connected to temperature control device one; the injection constant temperature chamber 13 is connected to temperature control device two; and the low-temperature constant temperature chamber 14 is connected to temperature control device three. Temperature control devices one, two, and three all include an insulation layer 19. Temperature control device one also includes a refrigerant coil one; temperature control device two also includes a refrigerant coil two; and temperature control device three also includes a refrigerant coil three 20. Refrigerant coil one, refrigerant coil two, and refrigerant coil three 20 are connected to a compressor, a refrigerant storage tank, and an expansion valve. These connections, along with the refrigerant coil three 20, form an air conditioning system. The refrigerant storage tank stores refrigerant. The refrigerant storage tank is connected to refrigerant coil 20 via throttle valve 3 and expansion valve 20. Refrigerant coil 20 serves as the evaporator of the air conditioning system. The compressor is connected to refrigerant coil 1 via throttle valve 1 and refrigerant coil 2 via throttle valve 2. Refrigerant coil 1 and refrigerant coil 2 serve as the condenser of the air conditioning system. The flow rate is controlled by throttle valve 1, throttle valve 2 and throttle valve 3, thereby controlling the temperature. The housing itself is made of sheet metal, which forms a support layer. A heat insulation layer 19 made of foam board is installed inside the support layer 18. The refrigerant coil is installed inside the heat insulation layer 19. A heat-conducting layer 21, made of stainless steel, is installed inside the refrigerant coil. The heat-conducting layer 21 forms the inner liner, where corresponding items are placed.

[0025] The enclosure is also equipped with a battery compartment 15, which contains a battery that drives the compressor and supplies power to the pressure hemostasis device.

[0026] The urination chamber 16 is connected to an exhaust port, and a filter 22 is installed at the exhaust port to prevent odor from escaping. Since a large amount of water and urine needs to be replenished and drained after surgery, the urination chamber 16 is a disposable chamber that can be pulled out. The urination chamber 16 is connected to a handle 23 and a hose 24. A quick connector 25 is installed at the end of the hose 24 to connect to the patient's urination tube. After use, the urination chamber 16 is centrally destroyed, and the chamber is cleaned, disinfected, and reused.

[0027] Clinically, it has been found that wounds located near the femoral or brachial artery close to the torso are often obscured by pressure-based hemostasis devices, resulting in higher temperatures. Therefore, a local cooling system is introduced. This system includes an air source; in this embodiment, the air source is a gas cylinder installed inside the enclosure, storing sterilized air. The air source is connected to a heat-conducting pipe 26 that mates with the low-temperature constant-temperature chamber and a heat-conducting pipe 2 that mates with the injection solution constant-temperature chamber. Heat-conducting pipe 26 is a metal tube and is attached to a refrigerant coil 3, thus outputting cold air. Heat-conducting pipe 2 is also a metal tube and is attached to a refrigerant coil 2, thus delivering... Hot air is emitted. Heat pipe 1 (26) is connected to the main valve through valve 1, and heat pipe 2 is connected to the main valve through valve 2. The air volume is adjusted by valve 1 and valve 2 to control the temperature of the air delivered to the main valve, which is controlled at 15-18℃. The main valve is connected to a nozzle, and the air velocity is controlled by the main valve. The nozzle is a flexible hose, and the outlet end of the nozzle is fixed to the human body with medical tape, so that the nozzle acts on the wound and slowly delivers low-temperature air to the vicinity of the wound to avoid local overheating. Since the required air flow is small, a detachable small gas canister is used.

[0028] The cardiovascular angiography nursing device provided in this embodiment has a universal nursing bed that can be used for different patients and surgeries, avoiding changes in the patient's position during transfer. The items in the multi-functional platform 6 are prepared separately according to the patient's condition, making it convenient to use. Since the nursing bed is not equipped with guardrails, it should be moved slowly during use to avoid shaking the patient and the risk of tipping over.

[0029] It is worth noting that the cardiovascular angiography nursing device provided in this embodiment is particularly suitable for centralized temporary care after cardiovascular angiography surgery, under the supervision of a physician.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
