Description

Technical Field

[0001] The present invention belongs to the technical field of medical auxiliary equipment, and in particular relates to a medical defecation auxiliary device for critically ill patients. Background Art

[0002] In medical scenarios, defecation is extremely critical for critically ill patients, especially those with acute myocardial infarction. During the treatment of acute myocardial infarction patients, the heart is in an extremely fragile state. During the defecation process, if the patient needs to exert force to assist defecation, this behavior will significantly increase the burden on the heart. Because when defecation is forced, the abdominal pressure of the human body will increase rapidly, which will lead to an increase in blood pressure, and the heart needs to bear greater pressure to maintain blood circulation. This process will cause a sharp increase in myocardial oxygen consumption, which can easily lead to the deterioration of the condition and greatly increase the risk of inducing serious complications such as acute heart failure and heart rupture, posing a great threat to the life safety of patients. There are serious hidden dangers in safety.

[0003] Under the existing technology, the defecation problem of critically ill patients is usually handled by lifting the patients and sending them to a special toilet device, and then sending the patients back to the bed after defecation. However, the patients themselves are seriously ill and weak, and can hardly support their bodies by themselves. In this case, it is undoubtedly an extremely difficult task for nursing staff to carry patients. Nursing staff often consumes a lot of physical strength. More importantly, due to the different weights of different patients, it is difficult for nursing staff to achieve perfect and smooth operation during the carrying process. Patients will inevitably unconsciously support their bodies with force during this process. Even extremely slight force may cause serious consequences for patients with myocardial infarction, further affecting the safety of the patient's defecation process, and affecting the convenience and efficiency of the patient's defecation care.

[0004] In addition, in order to alleviate the patient's difficulty in defecation, enema is sometimes used to assist defecation. However, if enema is used too frequently, it will also bring many adverse effects. Enemas mainly stimulate the intestinal wall to induce defecation reflex. Long-term and frequent use will gradually reduce the sensitivity of the intestine to this stimulation, leading to further weakening of the intestinal autonomous peristalsis function. This will not only increase the patient's dependence on enema, but may also cause intestinal mucosal damage and increase the risk of intestinal infection. From the perspective of rehabilitation care, impaired intestinal function will prolong the patient's recovery period and increase the difficulty of the nursing staff's work.

[0005] Therefore, a medical defecation assisting device for critically ill patients is proposed to solve the above-mentioned problems. Summary of the invention

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

[0020] 1. Through the provision of a movable hollow base, a critically ill patient shifting mechanism, an auxiliary support assembly and a lifting mechanism, when medical staff need to assist critically ill patients in defecation, the medical staff first moves the defecation assisting device to the side of the bed of the critically ill patient through the movable hollow base, then the medical staff turns the critically ill patient to a side-lying state, and then controls the lifting mechanism through the control panel and the PLC controller to adjust the critically ill patient shifting mechanism to the same height as the bed surface of the bed, and then the L-shaped waist board slides to the bed surface of the critically ill patient's bed, and the medical staff adjusts the critically ill patient in a side-lying state to a flat state, so that the critically ill patient is transferred to the critically ill patient shifting machine The control panel then controls the retraction of the moving end of the first electric push rod through the PLC controller. The first electric push rod adjusts the critically ill patient to a sitting position through the connecting strip and the supporting cloth cover, which can help defecation in the sitting state, and the discharged feces are collected by the collecting mechanism to avoid feces spilling and polluting the environment. This mechanism enables the auxiliary defecation device to have the function of convenient shifting of critically ill patients, without the need for medical staff to assist critically ill patients, and at the same time, there is no need to transfer the patient to the toilet device, which saves time and effort. During the whole process, the critically ill patient does not need to exert any effort by himself, thereby ensuring the safety of defecation for the critically ill patient, and at the same time improving the convenience and efficiency of defecation care for the critically ill patient.

[0021] 2. Through the auxiliary defecation mechanism and conveying components, when the critically ill patient is adjusted to a sitting position, the medical staff can control the operation panel and PLC controller to enable the auxiliary defecation mechanism and conveying components to spray 39℃-43℃ warm water to the perianal area of ​​the critically ill patient. The water flow at the appropriate temperature stimulates the perianal nerves, promotes intestinal peristalsis, helps critically ill patients relax the perianal sphincter, relieves defecation difficulties caused by long-term bed rest and diseases, facilitates the smooth discharge of feces, and relieves the patient's abdominal distension and discomfort. This process is natural and gentle, without the need for a cork opening. Suppositories can not only avoid destroying the normal physiological environment of the anus and rectum, but also avoid weakening the defecation reflex of critically ill patients and over-reliance on suppositories for defecation. In addition, the jet of warm water can effectively remove fecal residues and secretions in the anus, keep the area clean and hygienic, and reduce the risk of bacterial growth. This mechanism enables the auxiliary defecation device to gently assist defecation and automatically clean the anus. Critically ill patients do not need the help of suppositories for defecation, thereby avoiding the dependence of critically ill patients on suppositories when defecating, and can improve the effect and convenience of defecation care for critically ill patients.

[0022] 3. Through the electric heating tube, three-way reversing solenoid valve and normally closed solenoid valve, when the critically ill patient finishes defecation, the auxiliary defecation mechanism continues to spray warm water flow to the perianal area of ​​the critically ill patient for 30 seconds for cleaning. After 30 seconds, the auxiliary defecation mechanism sprays 39℃-43℃ air to the perianal area of ​​the critically ill patient for drying, avoiding discomfort and bacterial growth caused by the humid environment of the perianal area. After defecation, the medical staff transfers the critically ill patient who has finished defecation to the bed for rest through the critically ill patient transfer mechanism. The critically ill patient does not need to exert force during the whole defecation process, and will not increase the physical burden. This mechanism enables the defecation auxiliary device to have the function of drying the perianal area, and the critically ill patient does not need to exert excessive force during the defecation process, thereby improving the safety of defecation for the critically ill patient.

This component can support the legs of critically ill patients and ensure the convenience of critically ill patients' displacement.

[0036] A mounting through hole is provided on the lower surface of the mobile hollow base 1, and a lifting mechanism 6 is fixedly embedded in the hole wall of the mounting through hole. The lifting mechanism 6 includes a self-locking motor 61 fixedly embedded in the bottom end of the mobile hollow base 1, and the top of the self-locking motor 61 is fixedly connected to the bottom end of one of the threaded tubes 3.

The bottom end of the transmission chain 63 is movably connected to two U-shaped support bars 64, and the top of the U-shaped support bar 64 is fixedly connected to the inner wall of the top end of the mobile hollow base 1. This mechanism enables the device to have a convenient lifting and adjusting function and makes the device suitable for beds of different heights.

[0037] The inner wall of the mobile hollow base 1 is fixedly connected with a PLC controller 10 and a battery pack 11, the upper surface of the mobile hollow base 1 is provided with a rectangular through hole, and the hole wall of the rectangular through hole is fixedly connected with an auxiliary defecation mechanism 7, the auxiliary defecation mechanism 7 comprises a water tank 71 fixedly embedded in the top of the mobile hollow base 1, the upper surface of the water tank 71 is fixedly connected with a micro air pump 72, the air outlet end of the micro air pump 72 passes through the inner wall of the top end of the water tank 71, and is fixedly connected with a three-way reversing solenoid valve 73, the lateral air outlet end of the three-way reversing solenoid valve 73 is fixedly connected with a bend pipe 74, the air outlet end of the bend pipe 74 is fixedly connected with a vertical pipe 75, the bottom end of the vertical pipe 75 is fixedly connected with a normally closed solenoid valve 76, the top of the vertical pipe 75 is fixedly connected with a heating tube 77, the outlet nozzle of the heating tube 77 passes through the outer wall of the water tank 71, and is fixedly connected with a hose 78, the top of the hose 78 A conveying component 8 is fixedly connected, and the conveying component 8 includes a hollow block 81 fixedly connected to the top of the hose 78, an outer wall of the hollow block 81 is fixedly connected to an arc-shaped hard tube 82, and the top of the arc-shaped hard tube 82 is fixedly connected to a one-way nozzle 83, and the outer wall of the hollow block 81 is fixedly connected to a second electric push rod 84, and the fixed end of the second electric push rod 84 is fixedly connected to the upper surface of the water tank 71, and the outer wall of the pointed end of the heating cylinder 77 is fixedly embedded with a temperature sensor 79, and the side wall of the heating cylinder 77 is fixedly embedded with an electric heating tube 710, and the outer wall of the heating end of the electric heating tube 710 is fixedly sleeved with a plurality of heating meshes 711.

Severe patients do not need to rely on suppositories for defecation, thereby avoiding the dependence of critically ill patients on suppositories when defecating, and can improve the effect and convenience of defecation care for critically ill patients.

[0038] A collecting mechanism 9 is fixedly connected to the upper surface of the mobile hollow base 1, and the collecting mechanism 9 includes a limiting frame 91 fixedly connected to the upper surface of the mobile hollow base 1, and an inner wall of the limiting frame 91 is movably connected to a collecting box 92, and an outer wall of the collecting box 92 is fixedly connected to two symmetrically distributed handles 93. This mechanism can collect feces produced by defecation to prevent feces from spilling, and there is no need to transfer the patient to a toilet for defecation, which saves time and effort and improves the convenience and efficiency of defecation care for critically ill patients.

[0039] The first electric push rod 414, the self-locking motor 61, the micro air pump 72, the wireless Internet of Things 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 end of the PLC controller 10 through wires. The wireless Internet of Things module 416 can collect the time information of each stage of defecation of critically ill patients and upload it to the hospital's server, and organize and analyze the defecation of critically ill patients in the hospital's server, and feedback the rehabilitation effect of critically ill patients, that is, the faster the patient defecates, the better the rehabilitation effect. This is because after the critically ill patients recover, the critically ill patients themselves can use force or control when defecating, thereby improving the effect of defecation. On the contrary, the longer the defecation time is, the poorer the autonomy of the critically ill patients is, and the poorer the rehabilitation effect of the critically ill patients is, and it assists doctors in making accurate diagnoses for critically ill patients. The control panel 417 and the temperature sensor 79 are all electrically connected to the input end of the PLC controller 10 through wires. The above-mentioned power-on equipment and electrical connections are existing technologies and will not be repeated here.

[0040] The operating principle of the present invention is described as follows: when the medical staff needs to assist the critically ill patient in defecation, the medical staff first moves the defecation assisting device to the side of the bed of the critically ill patient by moving the hollow base 1, and then the medical staff turns the critically ill patient to a side-lying state so that the back and buttocks of the critically ill patient are exposed, and the critically ill patient is conveniently transferred to the critically ill patient shifting mechanism 4, and then the lifting mechanism 6 is controlled by the control panel 417 and the PLC controller 10 to adjust the critically ill patient shifting mechanism 4 to the same height as the bed surface of the bed. Specifically, the control panel 417 sends an electrical signal instruction to the PLC controller 10, and the PLC controller 10 controls the self-locking motor 61 after receiving the electrical signal instruction. After starting, the self-locking motor 61 drives one of the threaded cylinders 3 to rotate, and the four threaded cylinders 3 rotate simultaneously in the same direction through the transmission chain 63 and the plurality of sprockets 62, thereby ensuring that the four screws 12 can rise or fall together, and drive the two movable guide rails 41 to rise or fall together, and ensure that the height of the L-shaped waist board 44 matches the height of the bed surface of the critically ill patient bed, and then the medical staff pushes the L-shaped waist board 44 to slide on the movable guide rail 41 through the U-shaped handrail 415, and the limit slider 43 slides in the movable groove 42, and the sliding process of the L-shaped waist board 44 is also assisted by the universal ball 13, which uses the universal ball 13 to reduce the sliding friction and improve the sliding flexibility of the L-shaped waist board 44;

[0041] After the L-shaped lumbar board 44 slides to the bed surface of the critically ill patient's bed, the medical staff adjusts the critically ill patient who is lying on his side to a lying flat state. At this time, the critically ill patient's buttocks are located at the L-shaped lumbar board 44, and the critically ill patient's waist is supported by the lumbar support rod 47, and the critically ill patient's neck and head are supported by the neck rod 49 and the head rod 410 respectively, and the back support is assisted by the support cloth cover 411. At the same time, the leg bend rod 53 of the auxiliary support assembly 5 supports the critically ill patient's calf bend. The critically ill patient can be effectively lifted through multi-point support. Then the medical staff pulls back the critically ill patient's shifting mechanism 4 through the U-shaped armrest 415, so that the critically ill patient's shifting mechanism 4 returns to the initial state. At this time, the medical staff takes off the critically ill patient's pants, so that the critically ill patient's buttocks are exposed to facilitate defecation. Then the control panel 417 controls the moving end of the first electric push rod 414 to retract through the PLC controller 10. The moving end of the first electric push rod 414 retracts through the first connecting rod 10. The connecting ring 412 pulls the connecting strip 48, and the connecting strip 48 is deflected by the rotating rod 46. As the moving end of the first electric push rod 414 completes the contraction, the connecting strip 48 is deflected to a vertical state by the rotating rod 46, and the critically ill patient is adjusted from a lying position to a sitting position. The critically ill patient defecates through the elliptical defecation hole 45. When in a sitting position, the angle of the human intestine of the critically ill patient is more conducive to the discharge of feces, and the force of defecation can be reduced with the help of gravity. At the same time, the sitting position can also relax the abdominal muscles, which helps to increase abdominal pressure and promote defecation. The discharged feces are collected by the collection box 92 of the collection mechanism 9 to avoid feces leakage and pollution of the environment. The mechanism enables the auxiliary defecation device to have the function of convenient displacement of critically ill patients, without the need for medical staff to laboriously support the critically ill patients, and at the same time, there is no need to transfer the patients to the toilet equipment, which saves time and effort. During the whole process, the critically ill patients do not need to exert their own strength, which ensures the safety of defecation for the critically ill patients, and at the same time improves the convenience and efficiency of defecation care for the critically ill patients.

[0042] After the critically ill patient is adjusted to a sitting position, the medical staff first controls the electric heating tube 710 to preheat for 30 seconds through the control panel 417 and the PLC controller 10, and the electric heating tube 710 increases the temperature in the heating tube 77. Then the control panel 417 and the PLC controller 10 control the micro air pump 72 and the normally closed solenoid valve 76 to start. The micro air pump 72 draws air and sprays it through the bottom air outlet of the unpowered three-way reversing solenoid valve 73. The air increases the air pressure in the water tank 71, and then the water in the water tank 71 passes through the normally closed solenoid valve 76 and the vertical valve 73 opened by power. The straight pipe 75 is input into the heating cylinder 77, and the temperature of the water is increased by the temperature in the heating cylinder 77. The temperature sensor 79 monitors the temperature of the water discharged from the heating cylinder 77 to be between 39°C and 43°C. If the temperature sensor 79 detects that the water temperature sprayed from the heating cylinder 77 does not meet the temperature threshold of 39°C to 43°C preset by the PLC controller 10, the PLC controller 10 automatically adjusts the heating power of the electric heating pipe 710 to realize automatic water temperature control. Then, the warm water discharged from the heating cylinder 77 is discharged through the hose 78, the hollow block 81, the arc-shaped hard pipe 82 and the The one-way nozzle 83 sprays out, and at the same time, the PLC controller 10 also 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 hard tube 82 to adjust the position, so that the water flow sprayed by the arc-shaped hard tube 82 and the one-way nozzle 83 can be sprayed toward the anus of the critically ill patient. In addition, the injection speed of the micro air pump 72 can be controlled through the control panel 417 and the PLC controller 10, and the impact force of the water flow sprayed out of the one-way nozzle 83 can be controlled by adjusting the injection speed, so as to avoid the one-way nozzle 83 spraying water The impact force is too large and In order to avoid discomfort, warm water of 39-43℃ is sprayed on the perianal area of ​​critically ill patients. The water flow with suitable temperature stimulates the perianal nerves, promotes intestinal peristalsis, helps critically ill patients relax the perianal sphincter, relieves defecation difficulties caused by long-term bed rest and illness, facilitates the smooth discharge of feces, and relieves abdominal distension and discomfort. This process is natural and gentle, without the help of enema, which can not only avoid destroying the normal physiological environment of the perianal area and rectum, but also avoid weakening the defecation reflex of critically ill patients and over-reliance on enema for defecation.

[0043] In addition, the stimulation of the jet of warm water can dilate the local blood vessels around the anus, promote blood circulation, help alleviate the poor blood circulation around the anus caused by long-term bed rest, and also have a certain effect on preventing anal diseases such as hemorrhoids. At the same time, it is beneficial to the physical recovery of critically ill patients, and can effectively remove fecal residues and secretions in the anus, keep the local area clean and hygienic, reduce the risk of bacterial growth, and prevent complications such as anal skin infection and pressure sores. This mechanism enables the auxiliary defecation device to gently assist defecation and automatically clean the anus. Critically ill patients do not need to use suppositories to defecate, thereby avoiding the dependence of critically ill patients on suppositories when defecating, and can improve the effect and convenience of defecation care for critically ill patients.

[0044] When the critically ill patient has finished defecating, the auxiliary defecation mechanism 7 continues to spray warm water flow to the anus of the critically ill patient for 30 seconds for cleaning, so as to ensure the hygiene and cleanliness of the body of the critically ill patient after defecation. After 30 seconds, the PLC controller 10 not only controls the normally closed solenoid valve 76 to shut down, but also controls the three-way reversing solenoid valve 73 to be energized for 2 minutes. At this time, the airflow ejected by the micro air pump 72 enters the bent pipe 74 through the three-way reversing solenoid valve 73 that is energized and reversing, and then enters the heating cylinder 77 through the vertical pipe 75. The initial airflow causes the residual water in the heating cylinder 77, the hose 78, the hollow block 81 and the arc-shaped hard tube 82 to be sprayed out. After the residual water is sprayed out, the air The air flows through the electric heating tube 710 for heating and is also heated to the range of 39°C-43°C. The warm air is then blown toward the perianal area of ​​the critically ill patient for drying, thereby avoiding discomfort and bacterial growth caused by the humid environment around the perianal area. After 2 minutes, the PLC controller 10 controls the micro air pump 72 to cut off the power and close. Then the medical staff transfers the critically ill patient who has completed defecation to the bed for rest through the critically ill patient shifting mechanism 4. The critically ill patient does not need to exert any force during the entire defecation process and does not increase the burden on the body. The mechanism enables the defecation assist device to have the function of drying the perianal area, and the critically ill patient does not need to exert excessive force during defecation, thereby improving the safety of defecation for the critically ill patient.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
