Description

Technical Field

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

[0002] Thoracic surgery is a discipline that mainly diagnoses and treats chest diseases. In thoracic surgery, diseases such as lung cancer and mediastinal tumors often require surgical treatment. Lung cancer surgery is used to remove lung tumor tissue, and mediastinal tumor surgery is to remove abnormal tumors in the mediastinum. These operations require careful care after surgery, and drainage tubes need to be arranged on the surgical incisions for chest effusion and air accumulation to facilitate the patient's postoperative recovery. In addition, auxiliary equipment is also needed during the surgical care of thoracic surgery patients. For example, the patent authorization announcement number is CN215458456U, which discloses a thoracic surgery nursing aid.

[0003] At present, after the incision of thoracic surgery is sutured, the tension of the tissues on both sides of the incision increases due to factors such as local tissue edema and muscle contraction, which in turn causes the tissues to stretch outward. This not only makes the patient feel a tearing discomfort in the surgical incision, but also may cause a small amount of body fluid to leak out. The leaked body fluid will make the surgical incision too moist, interfering with the normal environment of the incision healing and delaying the healing process. At the same time, the moist environment provides a breeding ground for microorganisms, which can easily cause infection, resulting in symptoms such as redness, swelling, suppuration, fever, and pain in the surgical incision. This will not only affect the safety and efficiency of surgical incision recovery;

[0004] In addition, thoracic surgery patients need to stay in bed for a long time to recuperate after surgery, but long-term bed rest can easily lead to venous thrombosis, muscle atrophy, slow blood circulation and decreased cardiopulmonary function, which increases the probability of complications in thoracic surgery patients after surgery and also affects the patient's recovery effect.

[0017] On the surface of the convex base on the same side of the connecting plate, two extension blocks are fixedly connected. Threaded holes are formed in the upper surfaces of the extension blocks, and the inner walls of the threaded holes are threadedly connected with positioning bolts.

[0018] Compared with the existing technology, the advantages of a thoracic surgery nursing assistor are as follows:

[0019] 1. Through the set surgical incision crack prevention mechanism, when a thoracic surgery patient needs care after chest surgery, first arrange the two convex bases on both sides of the bed, then adjust the positions of the two convex bases through the universal wheels so that the U-shaped plate is placed horizontally above the bed, then cover the surgical incision crack prevention mechanism at the thoracic surgery chest surgical incision, and use tape to stick the two soft sheets close to the patient's chest skin, and then use two adjusting bolts to bring the two soft sheets closer to each other. When the soft sheets are close to each other, the tissues on both sides of the surgical incision will be pushed closer to each other, which can avoid the increase of tension of the tissues on both sides of the surgical incision due to local tissue edema and muscle contraction, thereby not only avoiding the patient from feeling the discomfort of tearing of the surgical incision, but also trying to avoid the situation where the tissues on both sides of the surgical incision produce fluid exudation due to increased tension.

[0020] 2. Through the air supply mechanism, air insulation mechanism and disposable air tube, the PLC controller controls the air supply mechanism, and the air supply mechanism delivers sterile dry air to the air insulation mechanism. At the same time, the electric heating tube is controlled by the PLC controller to start heating. The electric heating tube increases the temperature of the sterile dry air in the insulation tube. The temperature is consistent with the normal body temperature of the patient, avoiding excessive temperature causing chest skin burns in thoracic surgery patients. In addition, air that meets body temperature can increase cell activity at the surgical incision and accelerate healing. The heated sterile dry air is delivered to the surgical incision inside the elastic rubber sleeve through the disposable air tube, always keeping the surgical incision dry, and accelerating the recovery of the patient's surgical incision. Therefore, after the sterile dry air that meets the human body temperature is delivered to the chest surgical incision of the thoracic surgery patient, it can keep the surgical incision warm, promote local blood circulation, and facilitate wound healing. In addition, the dry and sterile air can prevent the surgical incision from being too moist due to exudate, reduce the growth of microorganisms, reduce the risk of infection, and avoid symptoms such as redness, swelling, suppuration, fever, and pain at the surgical incision. This mechanism enables the thoracic surgery nursing aid to not only have the function of assisting the gathering and anti-cracking of the tissues on both sides of the thoracic surgery incision, avoiding the discomfort caused by the increased tension of the tissues on both sides of the surgical incision, but also has the ability to monitor the safety of surgical incision rehabilitation, creating good conditions for patient rehabilitation and improving the efficiency and safety of patient rehabilitation.

[0021] 3. With the provided limb flexion and extension nursing mechanism, when thoracic surgery patients need to regularly perform limb flexion and extension exercises due to long-term bed rest after chest surgery, first move the position of the U-shaped plate through the convex base and universal wheels, and control the position of the limb flexion and extension nursing mechanism to meet the upper limb and lower limb exercises of thoracic surgery patients. Each exercise session lasts for 30 - 40 minutes, thereby reducing the complications and the decline of cardiopulmonary function caused by thoracic surgery. After that, exercise the patient's limbs through the limb flexion and extension nursing mechanism. The flexion and extension of the patient's limbs can promote blood circulation, especially the blood return of the lower limbs, reducing the risk of thrombosis. Secondly, it can improve the blood circulation of the limbs, provide nutrition for tissues, and is beneficial to the healing of surgical incisions. Moreover, from the perspective of overall function, it also helps to indirectly enhance cardiopulmonary function and promote the patient's recovery. It can reduce the probability of postoperative complications in thoracic surgery patients. And through the rotational speed sensor, the rotational speed of the turntable can be detected. Through the control of the PLC controller, it can avoid the situation that the degree of limb flexion and extension exercise is too intense and damages the patient's body, as well as avoid increasing the burden on the patient's cardiopulmonary function. This mechanism enables the thoracic surgery nursing aid to have the function of automatically flexing and extending the patient's limbs, which can not only reduce the probability of postoperative complications in thoracic surgery patients, but also improve the blood circulation of the limbs, provide nutrition for tissues, be beneficial to the healing and recovery of surgical incisions, and can promote the patient's cardiopulmonary function, improving the effect of patient rehabilitation care.

The side end of the heat insulation cylinder 61 is fixedly communicated with the output end of the micro air pump 51. The end of the heat insulation cylinder 61 far from the micro air pump 51 is fixedly embedded with an electric heating tube 62. The heating end of the electric heating tube 62 is fixedly sleeved with a plurality of heat diffusion mesh sheets 63. The air outlet end of the heat insulation cylinder 61 is movably and hermetically sleeved with the air inlet end of a disposable trachea 7. This mechanism can improve the cell activity at the surgical incision and accelerate the healing speed. The air outlet end of the air heat preservation mechanism 6 is movably and hermetically sleeved with a disposable trachea 7.

[0035] The upper surface of the U-shaped plate 3 is fixedly connected to a limb flexion and extension nursing mechanism 9, which includes a connecting frame 91 fixedly connected to the upper surface of the U-shaped plate 3, and the outer walls on both sides of the connecting frame 91 are jointly provided with mounting through holes, and the hole walls of the mounting through holes are installed with Z-shaped rocking arms 92 through rolling bearings, and the rod walls of the Z-shaped rocking arms 92 are fixedly sleeved with a turntable 93, and both ends of the Z-shaped rocking arms 92 are installed with anti-skid plates 94 through rolling bearings, and the top of the connecting frame 91 is fixedly connected to an electric push rod 95, and the moving end of the electric push rod 95 is fixedly connected to a mounting frame 96, and the bottom end of the mounting frame 96 is fixedly sleeved with a damping rubber tube 97, and the outer wall of the middle horizontal part of the Z-shaped rocking arm 92 is fixedly sleeved with a driving sprocket 98, and the bottom end of the connecting frame 91 A fixed frame 99 is fixedly connected, and a speed sensor 910 is fixedly embedded in the inner wall of the fixed frame 99.

The outer wall of the connecting frame 91 is provided with a through hole that matches the rotating end of the speed sensor 910. This mechanism enables the thoracic surgery nursing aid to have the function of automatic flexion and extension exercise of the patient's limbs, which can not only reduce the probability of postoperative complications of thoracic surgery patients, but also improve the blood circulation of the limbs, provide nutrition to tissues, and is beneficial to the healing and rehabilitation of surgical incisions, as well as promote the patient's cardiopulmonary function, thereby improving the effect of patient rehabilitation care.

[0036] The outer walls of the connecting box 12 and the disinfectant tank 14 are jointly provided with a screw hole 1, and the hole wall of the screw hole 1 is threadedly connected to a sealing plug 15, the bottom ends of the disinfectant tank 14 and the connecting box 12 are jointly provided with a screw hole 2, and the hole wall of the screw hole 2 is threadedly and sealingly connected to a waste plug 16, the surface of the convex base 1 on the same side of the connecting plate 41 is fixedly connected with two extension blocks 17, the upper surface of the extension block 17 is provided with a threaded hole, and the hole wall of the threaded hole is threadedly connected to a positioning bolt 18, the extension block 17 can ensure that the positioning bolt 18 can be arranged on the lower side of the bed board of the hospital bed, and can improve the stability of the use of the nursing aid.

[0037] The micro air pump 51, the electric heating tube 62 and the electric push rod 95 are all electrically connected to the output end of the PLC controller 13 through wires, and the temperature and humidity sensor 810 and the speed sensor 910 are electrically connected to the input end of the PLC controller 13 through wires. The above-mentioned electrical connections and power-on equipment are existing technologies and will not be repeated here.

[0038] The operating principle of the present invention is described as follows: when a thoracic surgery patient needs care after a thoracic surgery, firstly, two convex bases 1 are arranged on both sides of the hospital bed, then the positions of the two convex bases 1 are adjusted by the universal wheel 2, and then the positioning bolt 18 is rotated so that the top of the positioning bolt 18 is pressed and contacted with the bed board of the hospital bed, and the positioning effect is achieved, so that the U-shaped plate 3 is horizontally placed above the hospital bed, and then the elastic rubber sleeve 81 is covered on the thoracic surgery thoracic surgery incision, and the two soft thin sheets 83 are closely attached to the patient's chest skin, and then the soft thin sheets 83 are fixedly attached to the patient's chest skin by tape, and the temperature and humidity sensor 810 is inserted into the sealing rubber ring 89, and the detection end of the temperature and humidity sensor 810 is ensured to be closely attached to the gauze located on the outside of the thoracic surgery patient's chest surgery incision, the temperature and humidity sensor 810 can monitor in real time whether the gauze outside the surgical incision is wet due to body fluids, and the drainage tube at the surgical incision also passes through the exhaust sleeve 88, and the exhaust sleeve 88 can support and prevent extrusion protection for the drainage tube, so as to ensure that the drainage tube can be used normally and reliably;

[0039] After the soft sheet 83 is fixed, the two adjusting bolts 85 are rotated synchronously, and the adjusting bolts 85 move upwards and drive the two connecting rods 87 to deflect through the rotating bearing 86. The two connecting rods 87 pull the two side sheets 82 and the soft sheet 83 closer to each other. When the soft sheets 83 are closer to each other, the tissues on both sides of the surgical incision are pushed closer to each other, which can avoid the situation where the tension of the tissues on both sides of the surgical incision increases due to local tissue edema and muscle contraction, thereby not only avoiding the patient from feeling the discomfort of the surgical incision being torn, but also avoiding the situation where the tissues on both sides of the surgical incision exudate due to the increased tension.

[0040] Meanwhile, the PLC controller 13 also controls the air supply mechanism 5 and the air insulation mechanism 6 to work. Specifically, the PLC controller 13 controls the micro air pump 51 to work. The micro air pump 51 sucks the sterile air at the top of the disinfectant solution tank 14 through the hose 52 and the moisture removal cylinder 54, making the disinfectant solution tank 14 in a low-pressure environment. And the low-pressure disinfectant solution tank 14 sucks the outside air to supplement through the L-shaped air inlet pipe 58. After the outside air passes through the L-shaped air inlet pipe 58, it will enter the disinfectant solution layer 59 for disinfection treatment and generate sterile air. Moreover, the disinfectant solution layer 59 can also perform dust reduction and purification treatment on the air. Then, after the sterile air enters the moisture removal cylinder 54, it will be dehumidified by the breathable membrane cover 57. Finally, the clean and dry air passes through the breathable membrane cover 57, the conical ceramic breathable cover 56, the hose 52 and the micro air pump 51 and enters the heat insulation cylinder 61. At this time, the electric heating tube 62 is controlled by the PLC controller 13 to start heating. The electric heating tube 62 improves the efficiency of increasing the temperature of the sterile and dry air in the heat insulation cylinder 61 through the heat diffusion mesh 63. The heated sterile and dry air is transported to the surgical incision inside the elastic rubber sleeve 81 through the disposable trachea 7. And the heating power of the electric heating tube 62 is controlled by the PLC controller 13 and the temperature and humidity sensor 810. The temperature and humidity sensor 810 detects the temperature of the sterile and dry air input inside the elastic rubber sleeve 81, and the detected temperature value is sent to the PLC controller 13 in the form of an electric signal. If the temperature value detected by the temperature and humidity sensor 810 exceeds the preset threshold range of 37 - 38 degrees Celsius of the PLC controller 13, the PLC controller 13 timely controls the heating power of the electric heating tube 62 to ensure that the temperature of the sterile and dry air in the heat insulation cylinder 61 is similar to the human body temperature, avoiding the situation of scalding the chest skin of the thoracic surgery patients caused by too high temperature. If the gauze wrapped around the surgical incision is wet due to excessive body fluid, that is, when the humidity value of the gauze detected by the temperature and humidity sensor 810 exceeds the warning humidity preset by the PLC controller 13, the PLC controller 13 timely controls the air extraction power of the micro air pump 51 to increase, and accelerates the evaporation of the exuded body fluid by transporting more sterile and dry air to the surgical incision. Finally, the air is discharged through the exhaust sleeve 88, always keeping the surgical incision dry and accelerating the recovery speed of the patient's surgical incision. Therefore, after the sterile and dry air that conforms to the human body temperature is transported to the thoracic surgery patient's chest surgical incision, it can keep the surgical incision warm, promote local blood circulation, and be beneficial to wound healing. Moreover, the dry and sterile air can avoid the surgical incision from being too wet due to exudate, reduce the growth of microorganisms, reduce the infection risk, and avoid symptoms such as swelling, suppuration, fever, and pain at the surgical incision. This mechanism enables the thoracic surgery nursing assistant to not only have the function of assisting in gathering and preventing the splitting of the tissues on both sides of the thoracic surgery incision, avoiding the discomfort caused by the increased tension of the tissues on both sides of the surgical incision, but also have the ability to safely monitor the recovery of the surgical incision, and keep the surgical incision warm by transporting sterile and dry air that conforms to the human body temperature, and promote local blood circulation, which is beneficial to wound healing. Moreover, the dry and sterile air can avoid the surgical incision from being too wet due to exudate,Reduce microbial growth, lower the risk of infection, create good conditions for the patient's recovery, and improve the efficiency and safety of the patient's recovery;

[0041] When thoracic surgery patients need to regularly perform flexion and extension exercises of their limbs during long-term bed rest after chest surgery, first move the position of the U-shaped plate 3 through the convex base 1 and the universal wheels 2, and control the position of the limb flexion and extension nursing mechanism 9 to meet the upper limb exercise or lower limb exercise of thoracic surgery patients. Each exercise time is maintained for 30-40 minutes, so as to reduce the complications and the decline of cardiopulmonary function caused by thoracic surgery. And after the position of the convex base 1 is adjusted each time, the medical staff rotates the positioning bolt 18, and the positioning bolt 18 squeezes the bed board of the hospital bed to achieve the purpose of positioning. Moreover, the height of the U-shaped plate 3 is adjusted through the slider 10 and the sliding hole 11, so that the upper limb or lower limb of the patient can be comfortably placed on the two anti-slip plates 94. After the height of the U-shaped plate 3 is adjusted, then rotate the limit bolt 42, and the limit bolt 42 squeezes the surface of the convex base 1 to achieve the purpose of positioning the height of the U-shaped plate 3. Then, the limb flexion and extension nursing mechanism 9 is used to exercise the limbs of the patient. During the specific exercise process, the two upper limbs or lower limbs of the patient are respectively placed on the two anti-slip plates 94, and a limit semi-circular ring can also be installed on the anti-slip plate 94 to ensure the stability of the contact with the upper limb or lower limb of the patient. Then, the upper limb or lower limb of the patient drives the turntable 93 to rotate through the Z-shaped rocker 92. When the turntable 93 rotates, it contacts the damping rubber cylinder 97, and the frictional resistance of the contact can ensure the effect of the patient's limb exercise. The flexion and extension of the patient's limbs can promote blood circulation, especially the blood return of the lower limbs, reduce the risk of thrombosis. Secondly, it can improve the blood circulation of the limbs, provide nutrition for the tissues, and is beneficial to the healing of the surgical incision. And from the perspective of the overall function, it also helps to indirectly enhance the cardiopulmonary function and promote the recovery of the patient, and can reduce the probability of postoperative complications of thoracic surgery patients. When the Z-shaped rocker 92 rotates, it also makes the driven sprocket 911 rotate through the driving sprocket 98 and the transmission chain 912. The driven sprocket 911 drives the rotating end of the rotational speed sensor 910 to rotate, and can detect the rotational speed of the turntable 93. Moreover, the rotational speed sensor 910 can send the rotational speed of the turntable 93 to the PLC controller 13 in the form of an electrical signal. If the rotational speed of the turntable 93 exceeds the warning threshold of the PLC controller 13, the PLC controller 13 timely controls the mobile end of the electric push rod 95 to move downward, and the greater the rotational speed value detected by the rotational speed sensor 910, the greater the downward movement distance of the mobile end of the electric push rod 95, and the two are proportional. The downward movement of the mobile end of the electric push rod 95 will increase the friction between the damping rubber cylinder 97 and the turntable 93, thereby reducing the rotational speed of the turntable 93, avoiding the situation that the degree of limb flexion and extension exercise is too intense and damaging the patient's body, and avoiding increasing the burden on the patient's cardiopulmonary function. This mechanism enables the thoracic surgery nursing aid to have the function of automatically flexing and extending the limbs of the patient, which can not only reduce the probability of postoperative complications of thoracic surgery patients, but also improve the blood circulation of the limbs, provide nutrition for the tissues, be beneficial to the healing and recovery of the surgical incision, and can promote the cardiopulmonary function of the patient and improve the effect of patient rehabilitation nursing.
