Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to an operating table capable of preventing pressure injuries. Background Art

[0002] Pressure injury (PI) is a global health problem, especially more common in patients who are bedridden for a long time, undergo long-term surgery, are wheelchair-bound, and the elderly. This injury may not only cause local damage to the skin and subcutaneous tissue, but may also be accompanied by pain. In severe cases, it may cause a series of complications, such as secondary infection, osteomyelitis, and sepsis, which seriously affect the patient's health and quality of life. With the improvement of medical level and the enhancement of patient safety awareness, the requirements for patient comfort and safety during surgery are also getting higher and higher. The traditional operating table design has certain limitations in providing patient position support and comfort, especially in preventing pressure injuries.

[0003] Traditional operating tables have many shortcomings in preventing pressure injuries. For example, patients maintain the same posture for a long time during surgery, which may cause local tissue compression and increase the risk of pressure injuries. Traditional operating tables pay relatively little attention to patient positioning and comfort, which may cause patients to feel uncomfortable during surgery. In order to reduce the risk of pressure injuries, nurses need to take additional preventive measures, such as regularly changing the patient's position and using special cushions, which increases workload and complexity.

[0004] After searching, the Chinese patent with the announcement number CN221206016U discloses a split air cushion operating bed, including an operating bed body, a bed frame, a head support, a leg support, a tube support and a bracket. The operating bed body is fixedly connected to the bed frame, a head support is arranged at one end of the operating bed body, and a leg support is arranged at the other end. The head support and the leg support are separately connected to the operating bed body, and brackets are arranged at the four corners of the operating bed body. The bracket is fixedly connected to the operating bed body, and the tube support is separately connected to the operating bed body through the bracket. The operating bed body, the head support and the leg support include a plurality of vertical air bags. By setting the vertical air bags, the operating bed can be effectively inflated and deflated according to demand. In a long operation, intermittent inflation or deflation can be performed as needed to relieve the pressure on different parts; however, since the application cannot detect the blood oxygen saturation of the patient's body, it is impossible to timely judge whether the patient has pressure injury. At the same time, the application does not take into account the influence of temperature on the body's blood oxygen saturation, so there are problems of inconvenience in use and weak functionality. Summary of the invention

[0005] In view of the above-mentioned problems, the present invention aims to provide an operating bed that prevents pressure injuries. By designing a blood oxygen monitoring component, the blood oxygen saturation of the patient during surgery is monitored by multiple near-infrared spectrometer probes. By designing an air cushion component, when it is monitored that the blood oxygen saturation of parts of the patient's body is reduced, the air cushions in different parts are inflated to lift the body as a whole or partially, so that the patient's blood oxygen saturation is restored and pressure injuries are prevented. By designing a temperature control component, the temperature of the patient's body parts is adjusted through the temperature control layer. The bed has the advantages of simple structure, easy use, high comfort and comprehensive functions.

[0006] The main ideas of the technical solutions adopted in the present invention are: designing a blood oxygen monitoring component to monitor the patient's blood oxygen saturation during surgery through multiple near-infrared spectrometer probes evenly distributed on the air cushion; designing an air cushion component to inflate the air cushions in different parts to lift the patient's body as a whole or partially to restore the patient's blood oxygen saturation and prevent pressure injuries; designing a temperature control component to adjust the temperature of various parts of the patient's body through the temperature control layer in the air cushion.

[0007] In order to achieve the above object, the technical solution adopted by the present invention is as follows: A pressure injury prevention operating table comprises a base and a hydraulic support, wherein a bed support structure is rotatably provided on the hydraulic support, an air cushion assembly for preventing pressure injuries of patients is provided on the bed support structure, a blood oxygen monitoring assembly is provided on the air cushion assembly, and a temperature control assembly is also provided in the air cushion assembly.

[0008] The bed support structure comprises a head bed support, a back bed support, a buttocks bed support and a leg bed support which are rotatably connected in sequence, the bottom of the buttocks bed support is rotatably connected to a hydraulic support, and leg brackets are rotatably installed on both sides of the buttocks bed support.

[0009] The air cushion assembly comprises a head air cushion, a back air cushion, a buttocks air cushion and a leg air cushion respectively located on the top of the head bed support, the back bed support, the buttocks bed support and the leg bed support; the buttocks air cushion is provided with a buttocks-shaped air bag, and the leg air cushion is provided with an ankle-shaped air bag.

[0010] The air cushion assembly also includes waist fixing air cushions located on both sides of the buttocks bed frame support, and arm air cushions are also arranged on both sides of the back bed frame support.

[0011] The head air cushion, back air cushion, hip air cushion, leg air cushion, waist fixed air cushion and arm air cushion in the air cushion assembly are all provided with inflation ports which can be inflated or deflated by external equipment; the hip contour airbag or ankle contour airbag can be expanded and bulged by inflating the hip air cushion or the leg air cushion.

[0012] The blood oxygen monitoring component includes a plurality of near-infrared spectrometer probes evenly distributed on the back air cushion, the hip air cushion, the leg air cushion, the hip contour airbag and the ankle contour airbag. The blood oxygen monitoring component also includes a near-infrared spectrometer device, which can monitor the blood oxygen saturation of the patient's body through the near-infrared spectrometer probes.

[0013] Based on the above technical solution, further, an air jet structure is provided in the hip shaping air cushion, and the air jet structure includes sliding frames elastically and slidably installed on both sides of the hip shaping air cushion, and the sliding frames are located inside the hip shaping air cushion and are rotatably connected with soft sliders at both ends, and the soft sliders are slidably installed inside the hip shaping air cushion, and a plurality of air jet holes are provided on the surface of the hip shaping air cushion and the soft sliders; when the hip shaping air cushion bulges, the sliding frames on both sides contact with the waist fixed air cushions on both sides and are squeezed, and slide inward through the sliding frames, driving the soft sliders to slide, so that the hip shaping air cushion is connected with the outside world and sprays air to the outside.

[0014] The temperature control component includes a back temperature control layer, a buttocks temperature control layer and a leg temperature control layer fixed in the back air cushion, the buttocks air cushion and the leg air cushion. The back temperature control layer, the buttocks temperature control layer and the leg temperature control layer can be temperature-controlled by external devices respectively, thereby adjusting the temperature of the back air cushion, the buttocks air cushion and the leg air cushion respectively.

[0015] When the blood oxygen monitoring component detects that the blood oxygen saturation of a certain part of the patient's body is lower than the standard value, it can automatically drive the air cushion component to inflate, thereby expanding the hip-shaped airbag or the ankle-shaped airbag to lift most of the patient's body, or drive the temperature control component to provide the patient with a suitable temperature to reduce pressure injuries.

[0016] The back air cushion is also provided with a chest strap for assisting in fixing the patient's chest, and the leg air cushion is also provided with a leg strap for assisting in fixing the patient's legs.

[0017] A method for using an anti-pressure injury operating table comprises the following steps: S1. The patient lies flat on the operating table, and the positions of various parts of the body are adjusted so that the patient's hips and ankles are placed in the hip contour airbags and ankle contour airbags respectively, and the angle of the bed support structure is adjusted. The waist fixing air cushion can be selectively adjusted to fix both sides of the patient's waist, or the chest strap and leg strap can be used to fix the patient's chest and legs; S2. During the operation, the near-infrared spectrometer probes on the back air cushion, hip air cushion, leg air cushion, hip contour airbag and ankle contour airbag are monitored by the near-infrared spectrometer device, so as to monitor the blood oxygen saturation of various parts of the patient's body; S3. When the blood oxygen saturation of a certain part of the patient's body is monitored to be lower than the set standard value, the near-infrared spectrometer device automatically drives the air cushion component to inflate, inflate the hip contour airbag or the ankle contour airbag, and drives the temperature control component to heat the air cushion component to provide a suitable temperature for the patient, thereby assisting the patient's body's blood oxygen saturation to return to the standard value and preventing pressure injuries; S4. When the patient's blood oxygen saturation is lower than the set standard value, you can also choose to place the patient's legs on the leg support to assist in restoring the patient's blood oxygen saturation.

[0018] The beneficial effects of the present invention are: 1. An air cushion assembly is designed on the bed support structure, and various air cushions are used to support various parts of the patient's body. The blood oxygen saturation of various parts of the patient's body is monitored by the blood oxygen monitoring assembly. The temperature is adjusted by the hip-shaped airbag or the ankle-shaped airbag in the air cushion assembly and the temperature control layer, so that the patient's blood oxygen saturation is restored to normal, thereby alleviating the patient's pressure injury. The present invention has the advantage of being easy to use.

[0019] 2. The blood oxygen saturation of the patient is monitored by designing a blood oxygen monitoring component. When the blood oxygen saturation of the patient's body is reduced, the air cushion component is automatically inflated, and the patient is lifted as a whole by the hip contour airbag and the ankle contour airbag. The temperature control component is automatically used to heat the patient's body parts to reduce the patient's pressure injury, making the present invention comprehensive in function.

[0020] 3. By designing the air cushion components, especially the hip-shaped airbags and ankle-shaped airbags are designed for the hips and ankles of the human body. Under normal circumstances, the hip-shaped airbags and ankle-shaped airbags are in a concave state, which better fits the human body structure, and can improve the comfort of patients lying on this operating table.

[0021] 4. By designing an air cushion component and a blood oxygen monitoring component on the bed support structure of the operating bed, and designing a temperature control layer in each air cushion, the structure of the present invention is simple and easy to manufacture.

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0025] The inventors' research found that traditional operating beds have many shortcomings in preventing pressure injuries. For example, patients maintain the same posture for a long time during surgery, which may cause local tissue compression and increase the risk of pressure injuries. Traditional operating beds pay relatively little attention to patient positioning and comfort, which may cause patients to feel uncomfortable during surgery. At the same time, in order to reduce the risk of pressure injuries, nurses need to take additional preventive measures, such as regularly changing the patient's position and using special cushions, which increases the workload and complexity.

[0026] Based on the above findings, the present application proposes an anti-pressure injury operating bed, which designs a blood oxygen monitoring component and monitors the patient's blood oxygen saturation during surgery through multiple near-infrared spectrometer probes. It designs an air cushion component and, when it is detected that the blood oxygen saturation of a part of the patient's body decreases, it inflates the air cushions in different parts of the body to lift the body as a whole or partially, thereby restoring the patient's blood oxygen saturation and preventing pressure injuries. It also designs a temperature control component and regulates the temperature of the patient's body parts through the temperature control layer. The bed has the advantages of simple structure, easy use, high comfort and comprehensive functions.

[0027] See also Figure 1-Figure 5 The present application discloses an anti-pressure injury operating table, comprising a base 1 and a hydraulic support 2. Specifically, the structures of the base 1 and the hydraulic support 2 can refer to the existing operating table structure. A plurality of universal wheels 10 are fixed to the bottom of the base 1. The overall height of the hydraulic support 2 can be raised or lowered, thereby lifting or lowering the operating table body part on the top thereof. The hydraulic support 2 is rotatably provided with a bed support structure 3, see Fig.13 The bed support structure 3 includes a head bed support 301, a back bed support 302, a hip bed support 303 and a leg bed support 304 which are rotatably connected in sequence. Specifically, the bottom of the hip bed support 303 is rotatably connected to the top of the hydraulic support 2, so that the operating bed can be adjusted in angle or rotated as a whole through the hydraulic support 2. One end of the hip bed support 303 is rotatably connected to the back bed support 302 through a rotating shaft. One end of the back bed support 302 away from the hip bed support 303 is rotatably connected to the head bed support 301 through a rotating shaft. One end of the hip bed support 303 away from the back bed support 302 is rotatably connected to the two leg bed supports 304 through a rotating shaft. When performing surgery, the posture of the patient can be adjusted by rotating each bed support. The leg supports 305 are rotatably installed on both sides of the hip bed support 303. Specifically, connecting shafts are rotatably installed on both sides of the hip bed support 303 close to the leg bed support 304, and an arc-shaped support plate matching the curve of the human leg is installed on the top of the connecting shaft by means of a ball joint or the like. In some gynecological surgeries or anorectal surgeries with a long operating time, the patient's legs can be placed on the leg supports 305 to facilitate the recovery of the patient's leg blood oxygen saturation.

[0028] On both sides of the back bed support 302, arm bed supports 306 for placing the patient's arms are also fixed; at the same time, in the bed support structure 3, the overall material of the head bed support 301, the back bed support 302, the hip bed support 303, the leg bed support 304, the leg support 305, and the arm bed support 306 should be made of a metal material with a certain strength to ensure that the bed support structure 3 can provide stable support for the patient's body.

[0029] The bed support structure 3 is provided with an air cushion assembly 4 for preventing the patient from pressure injuries. Figure 6 , Figure 7 , Figure 8 as well as Fig.10 The air cushion assembly 4 includes a head air cushion 401, a back air cushion 402, a hip air cushion 403 and a leg air cushion 404 located on the top of the head bed support 301, the back bed support 302, the hip bed support 303 and the leg bed support 304, see Fig. 9 and Fig.11 The buttocks air cushion 403 is provided with a buttocks-shaped air bag 4031 , and the leg air cushion 404 is provided with an ankle-shaped air bag 4041 .

[0030] The two sides of the buttocks bed support 303 are also provided with waist fixing air cushions 405, see Fig.12 , arm air cushions 406 are also provided on both sides of the back bed support 302, specifically, arm air cushions 406 are provided above the arm bed supports 306 on both sides of the back bed support 302; In the air cushion assembly 4, the overall material of the head air cushion 401, the back air cushion 402, the hip air cushion 403, the leg air cushion 404, the waist fixed air cushion 405 and the arm air cushion 406 can be selected from materials with good elasticity such as leather or rubber, so that the comfort of the patient lying on the operating bed is improved, and the hip shaping airbag 4031 and the ankle shaping airbag 4041 should also have good elasticity. At the same time, since the hip shaping airbag 4031 and the ankle shaping airbag 4041 need to be deformed multiple times during use, the material of the hip shaping airbag 4031 and the ankle shaping airbag 4041 also needs to have good durability or toughness; each air cushion in the air cushion assembly 4 can be installed on the bed support structure 3 by bonding or with the help of connecting parts.

[0031] The head air cushion 401, back air cushion 402, buttocks air cushion 403, leg air cushion 404, waist fixed air cushion 405, and arm air cushion 406 in the air cushion assembly 4 are all provided with an inflation port 7 that can be inflated or deflated by an external device. The buttocks profiling airbag 4031 or the ankle profiling airbag 4041 can be expanded and bulged by inflating the buttocks air cushion 403 or the leg air cushion 404. For some operations that last longer, such as organ transplantation operations or neurosurgery operations, due to the long duration, the patient's body is in contact with the surface of the operating table for a long time, which is prone to pressure sores. At the same time, for some patients who are inconvenient to change beds after the operation, they are in a bedridden recovery state for a long time after the operation. By inflating the buttocks profiling airbag 4031 and the ankle profiling airbag 4041, the lower half of the patient's body can be lifted as a whole, which is convenient for the patient's body. The blood oxygen saturation recovery of the body is restored and the pressure sores on the body are alleviated.

[0032] See also Fig.14 In another embodiment of the present invention, an air jet structure 40311 can also be provided in the buttocks contoured air cushion 4031. Specifically, sliding frames 40312 are slidably installed on both sides of the buttocks contoured air cushion 4031. At the same time, a return spring 40315 is fixed at the connection between the inside of the buttocks contoured air cushion 4031 and the sliding frame 40312. The shape of the sliding frame 40312 is close to a three-way structure. The two ends of the buttocks contoured air cushion 4031 are rotatably connected with two soft sliders 40313 through a rotating shaft 40317. The soft The slider 40313 is slidably arranged in a slide rail 40316 provided on the inner side of the buttocks contouring air cushion 4031. A plurality of air jet holes 40314 are provided on the surface of the buttocks contouring air cushion 4031 and the soft slider 40313. It is worth mentioning that the slide frame 40312, the soft slider 40313, the return spring 40315, the slide rail 40316 and the rotating shaft 40317 are all made of soft materials, and can fit the inner surface of the buttocks contouring air cushion 4031 when it is not inflated, and will not affect the patient's use experience. When the buttocks contoured air cushion 4031 is inflated, the sliding frames 40312 on both sides swell up along with the buttocks contoured air cushion 4031 and contact the waist fixed air cushion 405 located on both sides of the buttocks bed frame support 303. The sliding frames 40312 are squeezed and slide toward the inside of the buttocks contoured air cushion 4031, and pull the soft slider 40313 to slide along the rotating shaft 40316. When the air jet hole 40314 on the soft slider 40313 is connected with the air jet hole 40314 located on the buttocks contoured air cushion 4031, air can be blown to the outside through the air jet hole 40314, thereby accelerating the air flow rate on the patient's back and legs, so as to alleviate the problem of bedsores or pressure sores on the back and legs of patients who have been bedridden for a long time. It should be noted that this part of the structure can be used when the patient is in the stage of bedridden recovery after surgery, so that the overall functionality and flexibility of the present invention are improved.

[0033] The air cushion component 4 is provided with a blood oxygen monitoring component 5, and the blood oxygen monitoring component 5 includes a plurality of near-infrared spectrometer probes 501 evenly distributed on the back air cushion 402, the buttocks air cushion 403, the leg air cushion 404, the buttocks contoured airbag 4031 and the ankle contoured airbag 4041. The blood oxygen monitoring component 5 also includes a near-infrared spectrometer device 502, and the near-infrared spectrometer device 502 can monitor the blood oxygen saturation of the patient's body through the near-infrared spectrometer probe 501; it should be noted that the near-infrared spectrometer probe 501 and the near-infrared spectrometer device 502 are both common near-infrared spectrometer products on the market, and their models are not described in detail in this article. In actual application, you can choose an existing product that can achieve the purpose of the present invention.

[0034] The air cushion component 4 is also provided with a temperature control component 6, which includes a back temperature control layer 601, a buttocks temperature control layer 602 and a leg temperature control layer 603 fixed in the back air cushion 402, the buttocks air cushion 403 and the leg air cushion 404. The back temperature control layer 601, the buttocks temperature control layer 602 and the leg temperature control layer 603 can be temperature-controlled by external devices, so as to adjust the temperature of the back air cushion 402, the buttocks air cushion 403 and the leg air cushion 404 respectively. When the patient undergoes some long-term surgery, the decrease in the patient's body temperature will also This causes the body's blood oxygen saturation to decrease, which can easily lead to problems such as pressure sores, slow metabolism or decreased coagulation ability. Heating the patient's body through the temperature control component 6 is helpful in assisting the patient's body temperature recovery, thereby alleviating various problems that occur in the patient's body. In some implementation schemes, the temperature control component 6 can also be connected to the infrared spectrometer device 502, so that when the infrared spectrometer device 502 detects that the patient's blood oxygen saturation is reduced, it automatically starts the temperature control component 6 to heat each air cushion in the air cushion component 4, thereby facilitating the patient's blood oxygen saturation recovery.

[0035] When the blood oxygen monitoring component 6 detects that the blood oxygen saturation of a certain part of the patient's body is lower than the standard value, it can automatically drive the air cushion component 4 to inflate, so that the hip-shaped airbag 4031 or the ankle-shaped airbag 4041 expands, thereby lifting most of the patient's body, or drive the temperature control component 5 to provide the patient with a suitable temperature to reduce pressure injuries.

[0036] The back air cushion 402 is also provided with a chest strap 8 for assisting in fixing the patient's chest, and the leg air cushion 404 is also provided with a leg strap 9 for assisting in fixing the patient's legs. The chest strap 8 and the leg strap 9 can use cloth or leather straps with Velcro or buckle structures.

[0037] A method for using an anti-pressure injury operating table comprises the following steps: S1. The patient lies flat on the operating table, and the positions of various parts of the body are adjusted so that the patient's buttocks and ankles are placed in the buttocks contour airbag 4031 and the ankle contour airbag 4041 respectively, and the angle of the bed support structure 3 is adjusted. The waist fixing air cushion 405 can be selectively adjusted to fix both sides of the patient's waist, or the chest strap 8 and the leg strap 9 can be used to fix the patient's chest and legs; S2. During the operation, the near-infrared spectrometer device 502 is used to monitor the near-infrared spectrometer probe 501 on the back air cushion 402, the buttocks air cushion 403, the leg air cushion 404, the buttocks profiling airbag 4031 and the ankle profiling airbag 4041, so as to monitor the blood oxygen saturation of various parts of the patient's body; S3. When the blood oxygen saturation of a certain part of the patient's body is monitored to be lower than the set standard value, the near-infrared spectrometer device 502 automatically drives the air cushion component 4 to inflate, and inflate the hip contour airbag 4031 or the ankle contour airbag 4041, and drives the temperature control component 6 to heat the air cushion component 4 to provide a suitable temperature for the patient, thereby assisting the patient's body's blood oxygen saturation to recover to the standard value and preventing pressure injuries; S4. When the patient's blood oxygen saturation is lower than the set standard value, the patient's legs can be placed on the leg support 305 to assist in restoring the patient's blood oxygen saturation.

[0038] Clinical application examples The patient lies flat on the bed and adjusts the positions of various parts of the body so that the body is evenly covered with the infrared spectrometer probe 501 on the back air cushion 402, the hip air cushion 403, and the leg air cushion 404, and the patient's hips and ankles are placed inside the hip contour airbag 4031 and the ankle contour airbag 4041. At this time, the medical staff can adjust the overall height of the bed support structure 3 or the rotation angle of each support according to the actual environment of the operation, and choose whether to use the waist fixing air cushion 405, the chest strap 8 or the leg strap 9 to fix the patient's body; During the operation, the patient's blood oxygen saturation data monitored by the near-infrared spectrometer probe 501 is obtained through the near-infrared spectrometer device 502 to monitor the patient's body's blood oxygen saturation in real time; When the patient is in a long-term operation state or a long-term bed rest and recovery state, the near-infrared spectrometer device 502 detects that the blood oxygen saturation of a certain part of the patient's body is lower than the standard value, and drives the air cushion in the air cushion component 4 corresponding to the patient's body to be inflated, and synchronously inflates the hip air cushion 403 and the leg air cushion 404, so that the hip profiling airbag 4031 and the ankle profiling airbag 4041 are inflated and expanded to lift most of the patient's body, and the jet structure 40311 on the hip profiling airbag 4031 is used to perform jet ventilation on the surface of the operating table located at the patient's back and legs; at the same time, the temperature control layer in the temperature control component 6 corresponding to the patient's body is driven to heat, and the blood oxygen saturation of the patient's body is assisted to recover by appropriately raising the temperature in combination with the lifting effect of the air cushion component 4; Optionally, the medical staff may also lift the patient's legs and place them on the leg support 305 to facilitate the recovery of the patient's blood oxygen saturation.
