Description

Technical Field

[0001] The present invention belongs to the technical field of thoracic surgery nursing equipment, and in particular relates to a bed fixing device for thoracic surgery nursing. Background Art

[0002] Thoracic surgery is mainly a surgery to treat organs in the chest cavity. After thoracic surgery, patients often need to lie in bed for a long time to recover. During this period, when caring for thoracic surgery patients, it is often necessary to fix the patient's chest surgical incision site to limit the range of movement of the patient's chest cavity and avoid secondary damage to the suture site of the patient's chest surgical incision. For example, the authorization announcement number CN217938574U discloses a bed fixing device for thoracic surgery nursing.

[0003] When in use, the above-mentioned thoracic surgery nursing bed fixing device restricts the thoracic surgery patient's range of movement by limiting the thoracic surgery patient, thereby preventing the thoracic surgery patient from having an excessive range of movement and causing secondary damage to the chest surgical incision. However, this fixing method has significant disadvantages. As the fixation time continues, the thoracic surgery patient's body will inevitably become stiff. When the human body maintains the same posture for a long time, the muscles and joints will become tense due to lack of movement. At this time, the patient instinctively needs to adjust the body posture to relieve discomfort. However, due to the restrictions of the bed fixing device, the patient is unable to change posture freely, and the physical discomfort cannot be effectively relieved, which can easily lead to discomfort and irritability. This negative impact is extremely detrimental to the patient's nursing effect, and may interfere with the patient's endocrine system and nervous system, affect the body's self-repair ability, slow down the healing speed of the wound, and even cause long-term adverse effects on the patient's psychological state.

[0004] In addition, current thoracic surgery patients face hidden dangers in the management of medical equipment when receiving postoperative care in the hospital bed. Patients usually need to connect to multiple medical monitoring devices, such as electrocardiogram monitors, blood oxygen saturation monitors, etc., and also use infusion catheters for auxiliary treatment. The wires of these infusion catheters and medical monitoring equipment are connected to the patient's body at one end and connected to different devices next to the bed at the other end. In the actual nursing process, the middle part of the infusion catheter and the wire are often draped on the bed at random, lacking effective fixing measures, resulting in easy shaking. Moreover, since the catheter and wire themselves have a certain weight, when they are in a suspended state for a long time, a pulling force will be generated on both ends. This may not only cause the infusion catheter and the wire of the medical monitoring device to accidentally fall off the patient's body, interrupting the medical monitoring data and preventing the auxiliary treatment from proceeding normally, seriously affecting the reliability of nursing, but worse, once this happens, it is very likely to cause a medical accident, seriously threatening the safety of thoracic surgery patients during bedside care.

[0017] Compared with the existing technology, the advantages of a thoracic surgery nursing bed fixing device are:

[0018] 1. By providing the supporting plate, chest postoperative incision restraint mechanism, second skin-friendly soft sheet, and suction pump, when a thoracic surgery patient lies on the main body of the hospital bed for nursing after surgery, the distance between the curved cover and the curved strip is first adjusted according to the size of the patient's chest surgical incision and limited. Then, the first skin-friendly soft sheet and the second skin-friendly soft sheet are placed on the skin on both sides of the patient's surgical incision and fixed with strong medical tape. Then, air is injected into the hollow block through the suction pump. The air pushes the connecting block to move. The connecting block, through the pulling action of the connecting rope, brings the curved strip and the curved cover closer to each other, and brings the skin between the curved cover and the curved strip closer to each other. This can avoid pain, discomfort, and secondary injury caused by large movements and pulling of the patient's chest postoperative incision. In addition, this fixing method does not restrict the patient's freedom in bed, allowing the patient to easily adjust their posture and relieve the stiffness and discomfort caused by lying in bed for a long time, as well as avoiding the patient's impatience during recovery in bed. This can not only improve the fixing effect of the device, but also improve the comfort and effectiveness of the patient's recovery, protecting the patient's physical and mental health.

[0019] 2. Through the setting of the fixing mechanism, when the patient is lying on the bed for care, it is inevitable to use medical monitoring equipment and infusion catheters for auxiliary treatment. By hanging the wires of the infusion catheter and the medical monitoring equipment in the fixing mechanism to limit the position, the wires and the infusion catheter are prevented from shaking violently and generating pulling force. At the same time, the wires of the infusion catheter and the medical monitoring equipment are prevented from accidentally falling off the patient's body, avoiding the interruption of medical monitoring data and the inability to carry out auxiliary treatment normally, and improving the reliability of patient care and the safety of patients during bed care.

[0020] 3. Through the feedback components and abnormal nursing reminder mechanism, when the patient is in the early stage of recovery on the hospital bed, the medical staff collects the patient's identity information with the help of the ID card reader and quickly transmits it to the wireless Internet of Things gateway. Then, when the chest postoperative incision restraint mechanism works, the feedback component focuses on detecting the humidity and skin temperature of the postoperative incision, and the detected data is sent to the PLC controller in the form of an electrical signal. The PLC controller controls the feedback component to detect once every 10 minutes, and uses the digital filtering algorithm to filter and denoise the data, and converts the original data through the preset formula. If the micro temperature sensor detects that the temperature of the patient's chest postoperative incision exceeds the body temperature threshold of 37.3 preset by the PLC controller, the PLC controller generates a corresponding postoperative incision fever reminder message. If the micro humidity sensor detects that the humidity of the patient's chest postoperative incision exceeds the humidity threshold preset by the PLC controller When on duty, the PLC controller generates corresponding reminder information of large amounts of body fluid exudation from the postoperative incision, and the PLC controller also controls the alarm to sound an alarm prompt. After that, the PLC controller sends the received data to the hospital cloud server through the wireless Internet of Things gateway. Then the treatment service system connected to the hospital cloud server promptly sends the patient's reminder information to the personal work computer of the doctor on duty. The doctor on duty can discover the patient's reminder information at the first time and run to the patient for emergency treatment in time, further improving the efficiency of handling abnormal patient care situations. This mechanism enables the bed fixing device to have the function of timely reminder of abnormal chest postoperative incision care. It can not only remind nurses or accompanying personnel in time at the nursing site, but also actively remind the doctor on duty to deal with abnormal situations in time to avoid medical accidents, thereby improving the reliability and safety of patients' postoperative care.

[0032] The upper surface of the supporting plate 10 is fixedly connected with an air pump 12 and an air intake cover 13. The air pump 12 is located inside the air intake cover 13. The air intake hole of the air intake cover 13 is provided with a connecting thread. The inner wall of the air intake hole of the air intake cover 13 is threaded and sealed with an air filter tank 19.

This mechanism can effectively fix the skin tissue next to the patient's chest surgical incision without restricting the patient's freedom. The patient can freely adjust his body posture in the bed to relieve the body stiffness caused by long-term use of the same posture, improve the patient's comfort in bed care, and prevent the patient from being affected by emotional impatience and affecting his physical health.

[0033] The outer sides of the three connecting ropes 710 are fixedly connected with a connecting strip 17, which can facilitate the simultaneous adjustment of the three connecting ropes 710. The bottom end of the arc strip 713 is fixedly connected with a second skin-friendly soft sheet 18. The second skin-friendly soft sheet 18 and the first skin-friendly soft sheet 74 are both made of inelastic soft materials, which can expand the contact area between the chest postoperative incision restraint mechanism 7 and the patient's chest skin, thereby improving the stability of the chest postoperative incision restraint mechanism 7.

This component can timely understand whether the patient's postoperative incision site is hot and a large amount of body fluid is leaking, thereby ensuring the safety of thoracic surgery patient care.

[0034] The inner wall of the air intake hood 13 is fixedly connected with a PLC controller 16 and a nursing abnormality reminder mechanism 8. The nursing abnormality reminder mechanism 8 includes a wireless Internet of Things gateway 81 and an ID card reader 82 fixedly connected to the inner wall of the air intake hood 13. The upper surface of the air intake hood 13 is fixedly connected with an alarm 83.

It can not only remind the nurse or accompanying personnel in time at the nursing site, but also actively remind the doctor on duty to deal with abnormal situations in time to avoid medical accidents, thereby improving the reliability and safety of postoperative care for thoracic surgery patients.

[0035] The air intake solenoid valve 61, the normally closed solenoid valve 72, the wireless Internet of Things gateway 81, the three-way reversing solenoid valve 14 and the alarm 83 are all electrically connected to the output end of the PLC controller 16 through a wiring harness, and the micro humidity sensor 93 and the micro temperature sensor 94 are electrically connected to the input end of the PLC controller 16 through a wiring harness. The above-mentioned power-on equipment and electrical connections are existing technologies and will not be repeated here.

[0036] The operating principle of the present invention is described as follows: when a thoracic surgery patient lies on the bed body 1 for nursing after surgery, the position of the movable block 3 is first adjusted by the guide rod 2, and the position of the carrier plate 10 is adjusted by the support rod 4 and the connecting sleeve 5 so that the carrier plate 10 is located at the patient's chest. Finally, the first limiting bolt 20 and the second limiting bolt 21 are used to tighten the carrier plate 10. Then, the distance between the arc cover 73 and the arc bar 713 is adjusted according to the size of the patient's chest surgical incision, and the position of the connecting rope 710 in the arc bar 713 is adjusted at the same time. Then, the extrusion bolt 716 is rotated to squeeze the limiting connecting rope 710 so that the connecting rope 710 and the arc bar 713 are fixed. 13 does not move relative to each other, ensuring that the distance between the arc cover 73 and the arc strip 713 is stable, and then the first skin-friendly soft sheet 74 and the second skin-friendly soft sheet 18 are placed on the skin on both sides of the patient's surgical incision, and the first skin-friendly soft sheet 74 and the second skin-friendly soft sheet 18 are adhered and fixed to the patient's skin with strong medical tape to complete the patient's chest postoperative care and fixation work. At the same time, the gauze used for chest surgical incision care is arranged on the lower side of the connecting rope 710 and the feedback component 9, and the connecting rope 710 and the feedback component 9 are used to limit the gauze. At the same time, the micro moisture sensor 93 of the feedback component 9 detects the moisture of the gauze;

[0037] When the chest postoperative incision restraint mechanism 7 is used, the device starts the air pump 12 and the three-way reversing solenoid valve 14 through the PLC controller 16 and is energized for 3 seconds. During this 3-second period, the air pump 12 delivers the sucked air to the inside of the arc cover 73 through the second conduit 71 through the three-way reversing solenoid valve 14, and then the air enters the inside of the hollow block 75 through the vent hole 717. The air entering the hollow block 75 pushes the connecting block 76 and the rubber ring 77 close to the air outlet one-way valve 79, and the connecting block 76 is connected to the air outlet one-way valve 79. The connecting rope 710 pulls the curved strip 713 and the curved cover 73 closer to each other, and the skin between the curved cover 73 and the curved strip 713 is brought closer to each other, thereby avoiding pain and discomfort caused by pulling on the patient's chest incision after surgery, and improving the nursing effect of the patient's chest incision after surgery. After 3 seconds, the PLC controller 16 controls the three-way reversing solenoid valve 14 to cut off power, and the three-way reversing solenoid valve 14 changes the air guide direction, so that the air in the second conduit 71 can be stably maintained.

[0038] When the patient's movement range is too large due to adjusting the lying posture on the bed, and there is a large pulling effect on the chest surgical incision, in the early stage of pulling, since the first skin-friendly soft sheet 74 and the second skin-friendly soft sheet 18 are on the outside of the chest postoperative incision and will be first affected by the pulling force, the second skin-friendly soft sheet 18 pulls the connecting rope 710 through the arc strip 713 and the extrusion bolt 716. The connecting rope 710 is forced to drive the connecting block 76 away from the air outlet check valve 79 and compress the air in the second conduit 71 and the arc cover 73. However, due to the corresponding compression resistance generated by the air compression, the arc strip 71 can be prevented from The distance between the curved strip 713 and the curved cover 73 is enlarged, and the postoperative incision between the curved strip 713 and the curved cover 73 can be prevented from being pulled and damaged by the patient's large adjustment of body posture, thereby avoiding secondary injury and pain and discomfort to the patient's chest postoperative incision. In addition, this fixing method does not restrict the freedom of the patient in the hospital bed, and the patient can easily adjust his posture and relieve the stiffness and discomfort caused by lying in bed for a long time, and avoid the patient's impatience during recovery in bed. It can not only improve the fixing effect of the device, but also improve the comfort and effect of the patient's recovery, and protect the patient's physical and mental health.

[0039] When the patient is lying on the bed for care, it is inevitable to use medical monitoring equipment and infusion catheters for auxiliary treatment. By hanging the wires of the infusion catheter and the medical monitoring equipment in different C-shaped support tubes 62 and adjusting the positions of the wires and the infusion catheter, when the PLC controller 16 controls the three-way reversing solenoid valve 14 to be energized for 3 seconds, the conduction direction of the three-way reversing solenoid valve 14 changes, and at the same time, the PLC controller 16 also controls multiple air intake solenoid valves 61 to be energized and opened for 3 seconds, and then the air pump 12 injects air into the cavity 11 through the first catheter 15 for 3 seconds, and then the air in the cavity 11 enters the expansion airbag 63 through the opened air intake solenoid valve 61, and the expansion airbag 63 is squeezed and inflated by the air, and the inflated expansion airbag 63 squeezes the wires and the infusion catheter on the C-shaped support tube 62. On the surface of the liquid catheter, at this time, due to the small squeezing force of the expansion airbag 63, it can only play the role of limiting the infusion catheter, and will not crush the infusion catheter to prevent infusion treatment. After 3 seconds, the PLC controller 16 controls the air pump 12 and the air inlet solenoid valve 61 to be powered off. After the power is off, the air inlet solenoid valve 61 will close to ensure that the air volume in the expansion airbag 63 is stable and the expansion airbag 63 will not be deflated. At this time, the fixing mechanism 6 stably suspends the infusion catheter and the wires of the medical monitoring device to avoid the wires and the infusion catheter from shaking significantly and generating pulling force. At the same time, it prevents the wires of the infusion catheter and the medical monitoring device from accidentally falling off the patient's body, avoiding the interruption of medical monitoring data and the inability to carry out auxiliary treatment normally, thereby improving the reliability of patient care and the safety of patients during bed care.

[0040] In addition, during the initial stage of the patient's recovery in the hospital bed, the medical staff places the patient's ID card on the ID card reader 82 to collect the patient's identity information, and the collected information is transmitted to the wireless Internet of Things gateway 81;

[0041] Then, when the chest postoperative incision restraint mechanism 7 is working, the micro humidity sensor 93 and micro temperature sensor 94 in the feedback component 9 will monitor the patient's postoperative incision exudate and fever. The micro temperature sensor 94 will detect the temperature of the patient's skin at the postoperative incision and send the temperature value in the form of an electrical signal to the PLC controller 16. At the same time, the micro humidity sensor 93 will detect the humidity of the outside of the patient's postoperative incision care gauze and send the humidity value in the form of an electrical signal to the PLC controller 16.

[0042] And the PLC controller 16 controls the feedback component 9 to detect the temperature and humidity of the patient's postoperative incision every 10 minutes. The PLC controller 16 will process the data received from the micro temperature sensor 94 and the micro humidity sensor 93, such as using a digital filtering algorithm to filter and denoise the data to remove external environmental interference signals and improve the accuracy of the data, and convert the collected raw data into actual physical values ​​through a preset conversion formula. After that, the PLC controller 16 transmits the received data information to the wireless Internet of Things gateway 81, wherein the wireless Internet of Things gateway 81 establishes a connection with the PLC controller 16 on the one hand, and obtains the data at the PLC controller 16 through communication interfaces such as serial ports and Ethernet ports. On the other hand, the wireless Internet of Things gateway 81 receives the patient identity information from the ID card reader 82, and integrates the two types of data, associates the corresponding patient identity information for each physiological data, and then converts the integrated data into a protocol and encrypts the data, and then sends the data to the hospital's cloud server through a wireless network. After receiving the data from the wireless Internet of Things gateway 81, the cloud server further processes and analyzes the data, such as backing up the data in real time to prevent data loss, and stores the data in a database. An index is established according to the patient's identity information, such as the ID number, to ensure that the data corresponds accurately, facilitate subsequent queries and statistical analysis, and classify and organize the data.

[0043] If the micro temperature sensor 94 detects that the temperature at the patient's chest postoperative incision exceeds the body temperature threshold of 37.3 degrees Celsius preset by the PLC controller 16, the PLC controller 16 generates a corresponding postoperative incision fever reminder message. If the micro humidity sensor 93 detects that the humidity at the patient's chest postoperative incision exceeds the humidity threshold preset by the PLC controller 16, the PLC controller 16 generates a corresponding postoperative incision large amount of body fluid exudation reminder message. The PLC controller 16 also controls the alarm 83 to sound an alarm prompt, reminding the accompanying personnel or nurses in the ward to call the doctor in time to deal with the abnormal situation. If a large amount of exudate is not handled in time, it is easy to cause postoperative incision infection, and if fever is not handled in time, it will increase the patient's metabolic burden and even cause septic shock, seriously endangering the patient's life safety.

[0044] At the same time, after receiving the reminder information from the PLC controller 16, the wireless Internet of Things gateway 81 promptly uploads the reminder information to the hospital's cloud server. Then, the treatment service system connected to the cloud server in the hospital promptly sends the patient's reminder information to the personal work computer of the doctor on duty. The doctor on duty can immediately find the patient's reminder information and rush to the patient for emergency treatment, further improving the efficiency of handling abnormal patient care situations.

[0045] Moreover, the collaborative work of the hospital's cloud server and treatment service system is an existing technology. Specifically, the wireless Internet of Things gateway 81 sends the integrated encrypted data to the cloud server. After receiving the data, the cloud server classifies and stores the data in the corresponding database table according to the established data storage rules. These data include patient identity information, temperature and humidity data of the postoperative incision. At the same time, the hospital's treatment service system and the cloud server are connected through a specific application program interface (API). This API is a set of predefined functions and protocols used to standardize data interaction between the two systems. It is an existing technology and will not be described in detail here. With the help of the API, the treatment service system actively initiates data requests to the cloud server at set time intervals (such as every 1 minute. In the request, the treatment service system will clearly specify the type of data to be obtained. For example, this request only obtains data related to reminder information. The cloud server receives the request Afterwards, the corresponding data is extracted from the database according to the request content, packaged in the format specified by the API, and then returned to the treatment service system. The data screening module in the cloud server monitors in real time and finds data that meets the reminder information conditions (such as the temperature detected by the micro temperature sensor 94 exceeds 37.3 degrees Celsius or the humidity detected by the micro humidity sensor 93 exceeds the threshold, and the PLC controller 16 generates a reminder information for uploading), marks and adds key information. After the treatment service system obtains the data, it classifies it according to the patient's identity, filters it according to the timestamp and integrity, and pushes the complete and latest reminder information to the personal work computer of the doctor on duty. This mechanism enables the bed fixing device to have the function of timely reminding the patient's chest postoperative incision care abnormalities. It can not only remind nurses or accompanying personnel in time at the nursing site, but also actively remind the doctor on duty to deal with abnormal situations in time to avoid medical accidents and improve the reliability and safety of postoperative care for thoracic surgery patients.
