Description

Technical Field

[0001] This invention belongs to the field of medical assistive device technology, and in particular relates to a defecation assistance device for critically ill patients. Background Technology

[0002] In medical settings, bowel movements are extremely critical for critically ill patients, especially those with acute myocardial infarction. During treatment, the heart of an acute myocardial infarction patient is in a very vulnerable state. If the patient has to exert effort to assist with bowel movements, this behavior will significantly increase the burden on the heart. This is because when straining to defecate, the abdominal pressure of the body will rise rapidly, which will lead to an increase in blood pressure. This will require the heart to bear greater pressure to maintain blood circulation. This process will cause a sharp increase in myocardial oxygen consumption, which can easily lead to a deterioration of the condition and greatly increase the risk of inducing serious complications such as acute heart failure and cardiac rupture. This poses a great threat to the patient's life and has serious safety risks.

[0003] Under current technology, dealing with the defecation problem of critically ill patients usually involves helping the patient up and taking them to a special commode to defecate, and then returning the patient to their bed. However, the patients are often seriously ill and weak, and can hardly support themselves. In this situation, the entire process of moving the patient by nursing staff is undoubtedly an extremely difficult task. Nursing staff often expend a lot of physical strength. More importantly, because different patients have different weights, it is difficult for nursing staff to operate perfectly smoothly during the process. During this process, the patient will inevitably unconsciously exert force to support their body. Even the slightest exertion can have serious consequences for patients with myocardial infarction, further affecting the safety of the patient's defecation process and the convenience and efficiency of defecation care.

[0004] In addition, to alleviate patients' difficulty in defecation, glycerin suppositories are sometimes used to assist in defecation. However, if glycerin suppositories are used too frequently, they can also have many adverse effects. Glycerin suppositories mainly stimulate the intestinal wall to trigger the defecation reflex. Long-term and frequent use will gradually reduce the sensitivity of the intestine to this stimulation, leading to a further weakening of the intestinal peristalsis function. This will not only increase the patient's dependence on glycerin suppositories, but may also cause damage to the intestinal mucosa and increase the risk of intestinal infection. From the perspective of rehabilitation nursing, the damage to intestinal function will prolong the patient's recovery period and increase the difficulty of nursing staff's work.

[0005] Therefore, a defecation assistance device for critically ill patients is proposed to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to address the above-mentioned problems by providing a medical device to assist in defecation for critically ill patients.

[0014] In the aforementioned medical defecation assistance device for critically ill patients, the lifting mechanism includes a self-locking motor fixedly embedded in the bottom end of a movable hollow base. The top end of the self-locking motor is fixedly connected to the bottom end of one of the threaded cylinders. Each of the four threaded cylinders has a sprocket fixedly sleeved at its bottom end. A transmission chain is sleeved on the outer wall of each of the four sprockets. Two U-shaped support bars are movably connected to the bottom end of the transmission chain. The top end of each U-shaped support bar is fixedly connected to the inner wall of the top end of the movable hollow base.

[0015] In the aforementioned medical defecation assistance device for critically ill patients, the defecation assistance mechanism includes a water tank fixedly embedded in the top of a movable hollow base. A miniature air pump is fixedly connected to the upper surface of the water tank. The air outlet of the miniature air pump passes through the inner wall of the top of the water tank and is fixedly connected to a three-way reversing solenoid valve. The horizontal air outlet of the three-way reversing solenoid valve is fixedly connected to a bend pipe. The air outlet of the bend pipe is fixedly connected to a vertical pipe. The bottom end of the vertical pipe is fixedly connected to a normally closed solenoid valve. The top end of the vertical pipe is fixedly connected to a heating cylinder. The outlet nozzle of the heating cylinder passes through the outer wall of the water tank and is fixedly connected to a flexible hose. The top end of the flexible hose is fixedly connected to a conveying component. A temperature sensor is fixedly embedded in the outer wall of the nozzle of the heating cylinder. An electric heating tube is fixedly embedded in the side wall of the heating cylinder. Multiple heating meshes are fixedly sleeved on the outer wall of the heating end of the electric heating tube.

[0016] In the aforementioned medical defecation assistance device for critically ill patients, the delivery assembly includes a hollow block fixedly connected to the top of a flexible tube, an arc-shaped rigid tube fixedly connected to the outer wall of the hollow block, a one-way nozzle fixedly connected to the top of the arc-shaped rigid tube, and a second electric push rod fixedly connected to the outer wall of the hollow block. The fixed end of the second electric push rod is fixedly connected to the upper surface of a water tank.

[0017] In the aforementioned medical defecation assistance device for critically ill patients, the collection mechanism includes a limiting frame fixedly connected to the upper surface of a movable hollow base, a collection box movably connected to the inner wall of the limiting frame, and two symmetrically distributed handles fixedly connected to the outer wall of the collection box.

[0018] In the aforementioned medical defecation assistance device for critically ill patients, the inner walls of the guide grooves of the two movable guide rails are all-purpose ball bearings that are rolled together, and the tops of the two ball bearings are fixedly connected to the lower surface of the L-shaped waist plate located in the vertical part.

[0019] Compared with existing technologies, the advantages of a medical defecation assistance device for critically ill patients are:

[0020] The system utilizes a movable hollow base, a critical care patient transfer mechanism, auxiliary support components, and a lifting mechanism. When medical staff need to assist a critically ill patient with defecation, they first move the defecation assistance device to the patient's bedside using the movable hollow base. Next, they turn the patient onto their side. Then, using the control panel and PLC controller, they adjust the lifting mechanism to align the critical care patient transfer mechanism with the bed surface. After the L-shaped lumbar support slides onto the bed surface, the medical staff adjust the patient from a side-lying position to a supine position, transferring the patient to the critical care patient transfer mechanism. Afterwards, the control panel controls the retraction of the first electric push rod's moving end via the PLC controller. The first electric push rod, through the connecting strip and support cloth cover, adjusts the critically ill patient into a sitting position. This sitting position facilitates defecation, and the excreted feces are collected by a collection mechanism to prevent leakage and environmental pollution. This mechanism enables the auxiliary defecation device to facilitate the transfer of critically ill patients, eliminating the need for medical staff to laboriously assist them or transfer them to the toilet. This saves time and effort, and the entire process does not require the critically ill patient to exert any effort, ensuring the safety of defecation for critically ill patients while improving the convenience and efficiency of defecation care for critically ill patients.

[0021] Through a specially designed defecation assistance mechanism and delivery component, once the critically ill patient is repositioned, medical staff can control the mechanism and delivery component via a control panel and PLC controller to spray warm water at 39℃-43℃ onto the patient's perianal area. The appropriately warm water stimulates the nerves in the perianal area, promoting intestinal peristalsis, helping the patient relax the anal sphincter, relieving defecation difficulties caused by prolonged bed rest or illness, facilitating smooth bowel movements, and reducing abdominal distension and discomfort. This process is natural and gentle, requiring no enemas. This not only avoids disrupting the normal physiological environment of the perianal and rectal area, but also prevents weakening the defecation reflex of critically ill patients and excessive reliance on glycerin suppositories. In addition, the sprayed warm water effectively removes fecal residue and secretions from the perianal area, maintaining local cleanliness and reducing the risk of bacterial growth. This device gently assists in defecation and automatically cleans the perianal area, eliminating the need for glycerin suppositories for critically ill patients, thus avoiding their dependence on glycerin suppositories and improving the effectiveness and convenience of defecation care for critically ill patients.

[0022] By incorporating an electric heating element, a three-way reversing solenoid valve, and a normally closed solenoid valve, after a critically ill patient finishes defecating, the assistive defecation mechanism sprays warm water onto the patient's anal area for 30 seconds to clean it. After 30 seconds, the assistive defecation mechanism sprays air at 39℃-43℃ onto the anal area to dry it, preventing discomfort and bacterial growth caused by a damp environment. After defecation, medical staff use a patient transfer mechanism to move the patient to a bed to rest. The entire defecation process requires no effort from the critically ill patient and does not increase the burden on their body. This mechanism enables the defecation assistance device to dry the anal area, and the process does not require excessive effort from the critically ill patient, improving the safety of defecation.

The critically ill patient transfer mechanism 4 includes two moving guide rails 41 arranged in parallel. The lower surface of one of the moving guide rails 41 is fixedly connected to the top ends of the two screws 12. The lower surface of another movable guide rail 41 is fixedly connected to the top ends of two other screws 12. Movable grooves 42 are provided on both sides of the two movable guide rails 41, and limit sliders 43 are slidably connected to the groove walls of the movable grooves 42. An L-shaped waist plate 44 is fixedly connected to the top ends of multiple limit sliders 43.

The top ends of the two universal ball bearings 13 are fixedly connected to the lower surface of the vertical part of the L-shaped waist plate 44. An elliptical drain hole 45 is provided in the middle of the horizontal part of the L-shaped waist plate 44, and a through hole is provided in the vertical part of the L-shaped waist plate 44. A rotating rod 46 is mounted on the wall of the through hole via a rolling bearing. A waist support rod 47 and a connecting strip 48 are fixedly sleeved on the wall of the rotating rod 46. A neck rod 49 and a head rod 410 are fixedly connected to the outer wall of the connecting strip 48. A support cloth sleeve 411 is sleeved on the outer walls of the waist support rod 47, neck rod 49, and head rod 410. A first connecting ring 412 and a second connecting ring 413 are fixedly connected to the outer walls of the connecting strip 48 and the L-shaped waist plate 44, respectively. A first electric push rod 414 is movably sleeved on the outer walls of the first connecting ring 412 and the second connecting ring 413. The two ends of the first electric push rod 414 are respectively provided with... A connecting ring 412 and a connecting ring 413 have connecting holes that mate with the outer walls of the two rings. A U-shaped handrail 415 is fixedly connected to the upper surface of the vertical part of the L-shaped waist plate 44. A wireless Internet of Things module 416 and a control panel 417 are fixedly connected to the outer wall of the U-shaped handrail 415. An auxiliary support component 5 is fixedly connected to the surface of the vertical part of the L-shaped waist plate 44. This mechanism enables the auxiliary defecation device to facilitate the transfer of critically ill patients without the need for medical staff to help them. The critically ill patients do not need to exert any effort during the entire process, ensuring the safety of defecation for critically ill patients and improving the convenience and efficiency of defecation care for critically ill patients.

[0035] The auxiliary support component 5 includes a connecting cover 51 that is fixedly connected to the outer wall of the vertical part of the L-shaped waist plate 44. A movable strip 52 is movably connected to the inner wall of the connecting cover 51. A leg bend bar 53 is fixedly connected to the outer wall of one end of the movable strip 52, and a stop block 54 is fixedly connected to the outer wall of the other end of the movable strip 52. This component can support the legs of critically ill patients and ensure the convenience of moving critically ill patients.

[0036] The lower surface of the movable hollow base 1 is provided with an installation through hole, and a lifting mechanism 6 is fixedly embedded in the wall of the installation through hole. The lifting mechanism 6 includes a self-locking motor 61 fixedly embedded in the bottom end of the movable hollow base 1. The top end of the self-locking motor 61 is fixedly connected to the bottom end of one of the threaded cylinders 3. The bottom ends of the four threaded cylinders 3 are all fixedly sleeved with sprockets 62. The outer walls of the four sprockets 62 are all sleeved with a transmission chain 63. The bottom end of the transmission chain 63 is movably connected to two U-shaped support bars 64. The top end of the U-shaped support bars 64 is fixedly connected to the inner wall of the top end of the movable hollow base 1. This mechanism enables the device to have convenient lifting and adjustment functions and makes the device suitable for hospital beds of different heights.

[0037] A PLC controller 10 and a battery pack 11 are fixedly connected to the inner wall of the mobile hollow base 1. A rectangular through hole is opened on the upper surface of the mobile hollow base 1, and an auxiliary defecation mechanism 7 is fixedly connected to the wall of the rectangular through hole. The auxiliary defecation mechanism 7 includes a water tank 71 fixedly embedded in the top of the mobile hollow base 1. A micro air pump 72 is fixedly connected to the upper surface of the water tank 71. The air outlet of the micro air pump 72 passes through the inner wall of the top of the water tank 71 and is fixedly connected to a three-way reversing solenoid valve 73. The horizontal air outlet of the three-way reversing solenoid valve 73 is fixedly connected to a bend 74. The air outlet of the bend 74 is fixedly connected to a vertical pipe 75. The bottom end of the vertical pipe 75 is fixedly connected to a normally closed solenoid valve 76. The top end of the vertical pipe 75 is fixedly connected to a heating cylinder 77. The outlet nozzle of the heating cylinder 77 passes through the outer wall of the water tank 71 and is fixedly connected to a flexible hose 78. The top end of the flexible hose 78... A conveying assembly 8 is fixedly connected to the device. The conveying assembly 8 includes a hollow block 81 fixedly connected to the top of a hose 78. An arc-shaped rigid tube 82 is fixedly connected to the outer wall of the hollow block 81. A one-way nozzle 83 is fixedly connected to the top of the arc-shaped rigid tube 82. A second electric push rod 84 is fixedly connected to the outer wall of the hollow block 81. The fixed end of the second electric push rod 84 is fixedly connected to the upper surface of the water tank 71. A temperature sensor 79 is fixedly embedded in the outer wall of the tip of the heating cylinder 77. An electric heating tube 710 is fixedly embedded in the side wall of the heating cylinder 77. Multiple heating meshes 711 are fixedly sleeved on the outer wall of the heating end of the electric heating tube 710. This mechanism enables the auxiliary defecation device to gently assist defecation and automatically clean the perianal area. Critically ill patients do not need to use glycerin suppositories to defecate, thereby avoiding the dependence of critically ill patients on glycerin suppositories during defecation and improving the effectiveness and convenience of defecation care for critically ill patients.

[0038] A collection mechanism 9 is fixedly connected to the upper surface of the movable hollow base 1. The collection mechanism 9 includes a limiting frame 91 fixedly connected to the upper surface of the movable hollow base 1. A collection box 92 is movably connected to the inner wall of the limiting frame 91. Two symmetrically distributed handles 93 are fixedly connected to the outer wall of the collection box 92. This mechanism can collect feces produced during defecation, prevent fecal spillage, and eliminate the need to move the patient to the toilet to defecate, saving time and effort and improving the convenience and efficiency of defecation care for critically ill patients.

[0039] The first electric push rod 414, the self-locking motor 61, the miniature air pump 72, the wireless IoT module 416, the three-way reversing solenoid valve 73, the normally closed solenoid valve 76, the electric heating tube 710, and the second electric push rod 84 are all electrically connected to the output terminal of the PLC controller 10 via wires. The wireless IoT module 416 can collect information on the time taken by critically ill patients at each stage of defecation and upload it to the hospital's server. The hospital's server can then organize and analyze the defecation situation of critically ill patients and provide feedback on the recovery effect of critically ill patients. That is, the faster the patient defecates, the better the recovery effect. This is because after the critically ill patients recover, they can exert force or control themselves during defecation, thus improving the defecation effect. Conversely, the longer the defecation takes, the worse the autonomy of the critically ill patients, and the worse the recovery effect. It also assists doctors in making accurate diagnoses for critically ill patients. The control panel 417 and the temperature sensor 79 are both electrically connected to the input terminal of the PLC controller 10 via wires. The above-mentioned electrical equipment and electrical connections are existing technologies and will not be described in detail here.

[0040] The operating principle of this invention is described as follows: When medical staff need to assist a critically ill patient with defecation, they first move the defecation assistance device to the patient's bedside using the hollow base 1. Then, they turn the patient into a side-lying position, exposing the patient's back and buttocks, facilitating transfer to the patient transfer mechanism 4. Next, the lifting mechanism 6 is controlled via the control panel 417 and the PLC controller 10 to adjust the patient transfer mechanism 4 to the same height as the bed surface. Specifically, the control panel 417 sends an electrical signal command to the PLC controller 10, which, upon receiving the command, controls the self-locking motor 61. Upon startup, the self-locking motor 61 drives one of the threaded cylinders 3 to rotate. All four threaded cylinders 3 rotate simultaneously in the same direction via the transmission chain 63 and multiple sprockets 62, thereby ensuring that the four screws 12 can rise or fall together, and drive the two moving guide rails 41 to rise or fall together, ensuring that the height of the L-shaped waist board 44 matches the height of the bed surface of the intensive care unit. Then, medical staff push the L-shaped waist board 44 to slide on the moving guide rail 41 via the U-shaped handrail 415, while the limiting slider 43 slides in the moving groove 42. The sliding process of the L-shaped waist board 44 is also assisted by the universal ball bearings 13, which reduce the sliding friction and improve the flexibility of the L-shaped waist board 44.

[0041] After the L-shaped lumbar support 44 slides onto the bed surface of the intensive care unit (ICU) bed, the medical staff adjusts the ICU patient from a side-lying position to a supine position. At this time, the ICU patient's buttocks are positioned at the L-shaped lumbar support 44, while the lumbar support bar 47 supports the ICU patient's lower back. The ICU patient's neck and head are supported by the neck support bar 49 and head support bar 410, respectively. The back support is further assisted by the support cover 411, and the leg support bar 53 of the auxiliary support component 5 supports the ICU patient's lower leg bends. This multi-point support effectively lifts the ICU patient. Next, the medical staff pulls back the ICU patient transfer mechanism 4 using the U-shaped handrail 415, returning the ICU patient transfer mechanism 4 to its initial state. At this point, the medical staff removes the ICU patient's pants, exposing the buttocks for easier defecation. Then, the control panel 417 controls the retraction of the moving end of the first electric push rod 414 via the PLC controller 10. The retraction of the moving end of the first electric push rod 414 is controlled by the first connecting... The connecting ring 412 pulls the connecting bar 48, which is deflected by the rotating rod 46. As the moving end of the first electric push rod 414 retracts, the connecting bar 48 is deflected to a vertical position by the rotating rod 46, allowing the critically ill patient to adjust from a lying position to a sitting position. The critically ill patient defecates through the oval defecation hole 45. In the sitting position, the angle of the critically ill patient's intestines is more conducive to the excretion of feces, and the force of gravity can be used to reduce the effort required for defecation. At the same time, the sitting position can also relax the abdominal muscles, which helps to increase abdominal pressure and promote defecation. The excreted feces are collected through the collection box 92 of the collection mechanism 9 to prevent fecal leakage and environmental pollution. This mechanism enables the auxiliary defecation device to facilitate the transfer of critically ill patients without the need for medical staff to help the critically ill patients or to transfer the patients to the toilet. It saves time and effort. The critically ill patient does not need to exert any effort during the whole process, ensuring the safety of defecation for critically ill patients, while improving the convenience and efficiency of defecation care for critically ill patients.

[0042] After the critically ill patient's sitting position is adjusted, medical staff first control the electric heating element 710 to preheat for 30 seconds via the control panel 417 and PLC controller 10. The electric heating element 710 increases the temperature inside the heating cylinder 77. Then, the control panel 417 and PLC controller 10 control the micro air pump 72 and normally closed solenoid valve 76 to start. The micro air pump 72 draws air and releases it through the bottom air outlet of the unenergized three-way reversing solenoid valve 73. The air increases the air pressure inside the water tank 71. Then, the water in the water tank 71 flows through the energized normally closed solenoid valve 76 and vertical... The straight pipe 75 inputs water into the heating cylinder 77, using the temperature inside the heating cylinder 77 to raise the water temperature. Temperature sensor 79 monitors the water temperature discharged from the heating cylinder 77, ensuring it is between 39℃ and 43℃. If temperature sensor 79 detects that the water temperature discharged from the heating cylinder 77 does not meet the preset temperature threshold of 39℃-43℃ for the PLC controller 10, the PLC controller 10 automatically adjusts the heating power of the electric heating element 710 to achieve automatic water temperature control. Afterwards, the warm water discharged from the heating cylinder 77 passes through the flexible hose 78, hollow block 81, and arc-shaped rigid pipe 82. The one-way nozzle 83 sprays water, and simultaneously, the PLC controller 10 controls the second electric push rod 84. The moving end of the second electric push rod 84 pushes the hollow block 81 and the arc-shaped rigid tube 82 to adjust their positions, so that the water flow from the arc-shaped rigid tube 82 and the one-way nozzle 83 can be sprayed towards the perianal area of ​​the critically ill patient. Furthermore, the control panel 417 and the PLC controller 10 can control the air injection speed of the micro air pump 72, and adjust the air injection speed to control the impact force of the water flow from the one-way nozzle 83, preventing the impact force of the water flow from the one-way nozzle 83 from being too large. In cases of discomfort, spraying warm water at 39℃-43℃ onto the perianal area of ​​critically ill patients can stimulate the nerves in the perianal area with water of a suitable temperature, which can promote intestinal peristalsis, help critically ill patients relax the perianal sphincter, relieve defecation difficulties caused by prolonged bed rest and illness, facilitate the smooth expulsion of feces, and reduce abdominal distension and discomfort. This process is natural and gentle, and does not require the use of glycerin suppositories. This not only avoids disrupting the normal physiological environment of the perianal rectum, but also avoids weakening the defecation reflex of critically ill patients and excessive reliance on glycerin suppositories for defecation.

[0043] In addition, the stimulation of the sprayed warm water can dilate local blood vessels in the perianal area, promote blood circulation, and help alleviate poor blood circulation in the perianal area caused by prolonged bed rest. It also plays a certain role in preventing perianal diseases such as hemorrhoids. At the same time, it is beneficial to the physical recovery of critically ill patients. It can also effectively remove fecal residue and secretions in the perianal area, keep the area clean and hygienic, reduce the risk of bacterial growth, and prevent complications such as perianal skin infection and pressure sores. This device has the functions of gently assisting defecation and automatically cleaning the perianal area. Critically ill patients do not need to use glycerin suppositories to defecate, thus avoiding their dependence on glycerin suppositories and improving the effectiveness and convenience of defecation care for critically ill patients.

[0044] After the critically ill patient finishes defecating, the auxiliary defecation mechanism 7 continues to spray warm water around the patient's anus for 30 seconds to cleanse the area and ensure hygiene. After 30 seconds, the PLC controller 10 not only controls the normally closed solenoid valve 76 to close, but also controls the three-way reversing solenoid valve 73 to be energized for 2 minutes. At this time, the airflow from the micro air pump 72 enters the bend pipe 74 through the energized three-way reversing solenoid valve 73, and then enters the heating cylinder 77 through the vertical pipe 75. The initial airflow causes the residual water in the heating cylinder 77, hose 78, hollow block 81, and arc-shaped rigid pipe 82 to be sprayed out. After the residual water is sprayed out, the air... The air is heated through the electric heating tube 710 to a temperature range of 39℃-43℃. Then, the warm air is blown onto the perianal area of ​​the critically ill patient to dry it, avoiding discomfort and bacterial growth caused by a damp environment. After 2 minutes, the PLC controller 10 controls the micro air pump 72 to shut off. Then, medical staff use the critically ill patient transfer mechanism 4 to transfer the critically ill patient who has finished defecating to the bed to rest. The entire defecation process does not require the critically ill patient to exert any effort and will not increase the burden on the body. This mechanism enables the defecation assistance device to have the function of perianal drying, and the critically ill patient does not need to exert excessive effort during the defecation process, thus improving the safety of defecation for critically ill patients.

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.
