Description

Technical Field

[0001] The invention belongs to the technical field of medical instruments, and in particular relates to a postoperative hemostasis nursing device for rehabilitation of thoracic surgery. Background Art

[0002] Thoracic surgery involves many vascular-rich organs and tissues in the chest cavity, such as the heart and lungs. The surgery is traumatic, vascular damage is difficult to avoid, and bleeding is easy to occur after the operation. Therefore, special hemostatic care is generally required after thoracic surgery to prevent bleeding from the wound, help the incision heal, and promote patient recovery.

[0003] At present, postoperative hemostasis care for thoracic surgery generally uses a bandage to tie a tourniquet, dressing, etc. to the surgical incision. The bandage can be used to apply a certain pressure to the incision with the tourniquet, etc., and the compression hemostasis method promotes the healing of the incision and reduces the possibility of bleeding from the incision. For example, a postoperative hemostasis care device for thoracic surgery rehabilitation is disclosed in patent announcement number CN211460369U;

[0004] The incision during thoracic surgery is close to the chest cavity. The rise and fall of the chest cavity during breathing will affect the incision. The chest cavity expands during inhalation, and the pressure between the wound and the binding increases accordingly. This will not only aggravate the patient's pain. If the pressure exceeds the tolerance range, it may also cause the wound that has just stopped bleeding to bleed again. This will undoubtedly hinder the healing of the incision, increase the risk of infection, and prolong the recovery period. Summary of the invention

An insulating bracket 183 corresponding to the position of the detection tube 181 is fixedly installed at the top of the plastic cushion block 2, and the humidity-sensitive element 182 is installed at the bottom of the insulating bracket 183. The humidity-sensitive element 182 is electrically connected to the controller 3, and each electric control valve 164 is electrically connected to the controller 3. Within a certain humidity range, the resistance of the humidity-sensitive element 182 decreases as the humidity increases.

[0037] The operating principle of the present invention is described as follows: When performing hemostasis protection on the postoperative incision of a patient, the movable end of the binding strap 10 is passed around the patient's back so that the plastic cushion block 2 is located at the thoracic incision of the patient. Then, the movable end of the binding strap 10 is passed through the adjustment channel 111. Then, the incision of the patient is disinfected and covered with a dressing. Then, the plastic cushion block 2 is placed at the incision so that the gauze pad 4 covers the dressing. Subsequently, the connecting block 8 is abutted against the side wall of the plastic cushion block 2, and the movable end of the binding strap 10 is pulled so that the binding strap 10 exerts an appropriate binding force on the patient, and the plastic cushion block 2 is stably bound to the patient's body. Then, the adjustment bolt 113 is rotated so that the pressing block 112 is stably abutted against the binding strap 10, thereby fixing the binding strap 10 and the connecting block 8. Subsequently, the medical staff sets appropriate pressing force and tension force on the controller 3 according to the patient's body type, incision size, position, etc., and then starts the controller 3;

[0038] After the controller 3 is started, it will immediately control the electromagnetic push rod 122 to work. The electromagnetic push rod 122 will push the pressure regulating piston 123 to move, so as to push the hydraulic oil 127 inside the hollow column 121 through the pressure regulating hose 124, the hollow block 125 and the liquid injection pipe 126 into the pressure cylinder 5. Under the action of the hydraulic oil 127, the moving piston 6 will move in the direction away from the connecting block 8, so as to gradually tighten the pull rope 94, so that the tension detector 92 detects the tension. When the tension value reaches the tightening force preset by the medical staff, the controller 3 controls the electromagnetic push rod 122 to maintain the current energizing current intensity. When the patient breathes, the patient inhales, and his chest will bulge. At this time, due to the body bulge, the tension on the strap 10 increases, so the tension detected by the tension detector 92 will also increase synchronously. After the tension detected by the tension detector 92 increases, the controller 3 will control the current intensity flowing into the electromagnetic push rod 122 to decrease synchronously, so that the regulating piston starts to move back. At this time, under the action of the tension, the moving piston 6 starts to move back, and the excess hydraulic oil 127 will flow back into the hollow column 121. When the moving piston 6 moves back, the pull rope 94 will move outward, so the strap 10 will drive the connecting block 8 to move in the direction away from the plastic cushion block 2, that is, when the patient inhales and the chest bulges, the strap 10 will drive the connecting block 8 to move in the direction away from the plastic cushion block 2. Cooperating with the pull rope 94, the length between the movable end of the strap 10 and the plastic cushion block 2 can be increased. Therefore, the binding force of the strap 10 on the patient is reduced, so as to balance the increase in the pressure between the incision and the plastic cushion block 2 caused by the chest bulge when the patient inhales, ensure that the binding force on the patient's incision remains stable, avoid further increasing the pain of the incision due to excessive binding pressure, and can avoid bleeding from the incision due to excessive pressure. Similarly, when the patient exhales, since the chest bulge disappears, the tension detected by the tension detector 92 decreases, so the controller 3 will control the electromagnetic push rod 122 to perform an extending action again, so that the moving piston 6 moves in the direction away from the connecting block 8 again until the tension detected by the tension detector 92 reaches the set value;

[0039] After the controller 3 is started, the controller 3 also controls the peristaltic pump 153 to work. The peristaltic pump 153 pumps out the disinfected alcohol in the liquid storage chamber 151 and transports the disinfected alcohol to the compression groove 13 through the infusion tube 154 and the liquid inlet flexible hose 155. As the disinfected alcohol in the compression groove 13 increases, the hydraulic pressure in the compression groove 13 becomes higher. At this time, the elastic sealing membrane 14 begins to expand under the action of the hydraulic pressure, so as to cooperate with the gauze pad 4 to apply pressure to the patient's incision (this pressure directly acts on the incision from the vertical direction to ensure the compression hemostasis effect on the incision). After the hydraulic detection probe 159 detects that the hydraulic pressure reaches the hydraulic value preset by the medical staff, the hydraulic detection probe 159 feeds back an electrical signal to the controller 3. At this time, the controller 3 controls the pressure regulating valve 158 to be energized and opened, so that the excess disinfected alcohol entering the compression groove 13 flows back to the liquid storage chamber 151 through the return flexible hose 156 and the return rigid tube 157. Secondly, the controller 3 also controls the semiconductor cooler 171 and the cooling fan 172 to work. When the semiconductor cooler 171 works, it can refrigerate the disinfected alcohol in the liquid storage chamber 151 (the refrigeration temperature is 15°C ± 3°C) and transfer the heat from the refrigeration end to the heating end. Under the action of the cooling fan 172, the air flow in the installation cavity 152 is discharged through the heat dissipation holes 173. When the air flow passes through the semiconductor cooler 171, it can transfer the heat at its hot end to ensure the continuous refrigeration effect of the semiconductor cooler 171. By reducing the temperature of the disinfected alcohol, the temperature at the incision can be reduced. Through the way of cold compress and compression, the healing of the incision can be promoted, the bleeding at the incision can be reduced, and the bacteria growth at the incision can be reduced to a certain extent, improving the protection effect on the incision. The controller 3 controls the semiconductor cooler 171 to work once every 1 hour, and the single working time is 15 minutes to avoid the long-term low temperature affecting blood circulation;

[0040] After the controller 3 is started, the controller 3 will connect the connection circuit with the humidity-sensitive element 182. Since there is no disinfection alcohol on the gauze pad 4 initially, the humidity at the humidity-sensitive element 182 is relatively low. At this time, the resistance of the humidity-sensitive element 182 is relatively large. Therefore, the measurement circuit of the controller 3 measures that the electrical signal intensity of the connection circuit with the humidity-sensitive element 182 is relatively low. At this time, the controller 3 will control each electromagnetic control valve 164 to be energized and opened. At this time, part of the disinfection alcohol in the pressing groove 13 will flow into the frame groove 162 of the plastic frame 161 through the shunt pipe 163, and then the disinfection alcohol is adsorbed by the gauze pad 4, so that the gauze pad 4 can adsorb the disinfection alcohol. After the gauze pad 4 adsorbs the disinfection alcohol, it can perform antibacterial disinfection around the incision. As the disinfection alcohol is discharged through the shunt pipe 163, part of the disinfection alcohol begins to volatilize under the action of its own volatile characteristics, and carries moisture away through the detection pipe 181. The humidity-sensitive element 182 in the detection pipe 181 will detect an increase in the humidity in the air (the ethanol in the disinfection alcohol is generally 75%, and the water solution is 25%. When ethanol volatilizes, it will carry moisture and escape). At this time, the resistance of the humidity-sensitive element 182 decreases due to the increase in humidity. When the humidity is higher than 65%, the measurement circuit of the controller 3 detects that the electrical signal of the connection circuit with the humidity-sensitive element 182 is higher than 10 mA. Therefore, at this time, the controller 3 will control each electromagnetic control valve 164 to be de-energized and closed. Since the gauze pad 4 adsorbs the disinfection alcohol, the humidity at the humidity-sensitive element 182 will be temporarily higher than 65% under the action of the disinfection alcohol volatilizing in the gauze pad 4. As the disinfection alcohol in the gauze pad 4 becomes less and less, the humidity at the humidity-sensitive element 182 will decrease again. When the humidity is lower than 65%, the controller 3 will control the electromagnetic control valve 164 to open again to replenish the disinfection alcohol for the gauze pad 4 to ensure that the gauze pad 4 maintains a continuous antibacterial disinfection effect around the incision.
