Description

Technical Field

[0001] The invention belongs to the technical field of medical drainage instruments, and in particular relates to a cardiovascular care drainage device. Background Art

[0002] In cardiovascular care, postoperative wound treatment is a key link. Since cardiovascular surgery is complex and traumatic, it is easy to produce a lot of blood and exudate. In order to quickly heal the postoperative wound, the blood and exudate produced in the wound need to be drained out in time. The doctor can judge the condition of the patient's wound through the drained fluid, which is beneficial for treatment.

[0003] At present, commonly used postoperative wound drainage devices generally include a drainage bottle, a drainage hose, a connector, a negative pressure mechanism, etc., and a certain degree of negative pressure is generated in the drainage bottle by the negative pressure mechanism. By using the negative pressure, the accumulated fluid in the wound can be introduced into the drainage bottle through the drainage hose, such as a drainage nursing device for elderly cardiovascular medicine disclosed in patent publication number CN213723947U;

[0004] The patient's postoperative wound will not only produce oozing blood, but also pus and other fluid accumulation. The amount of pus is usually small, and during drainage, it is usually discharged directly into the drainage bottle and mixed with blood. This will cause the pus and other fluid accumulation to be covered by the blood. On the one hand, it will cause the amount of blood drained from the drainage bottle to be falsely high, affecting the medical staff's judgment on the blood exudation of the wound. On the other hand, it may cause medical staff to be unable to promptly discover the occurrence of pus and other fluid accumulation in the wound, which is not conducive to timely treatment of the patient's wound and results in poor use effect.

[0015] 1.

[0017] 3.

Secondly, through the counting alarm component, based on the amount of blood and pus discharged, after the amount of exudate in the drainage bottle reaches the maximum value, an automatic alarm can be set to remind medical staff to transfer out the exudate in the drainage bottle in time. At the same time, through the cooperation of the grooves, arc-shaped thermal insulation blocks, thermistors and the second electromagnetic switch, when the patient continuously exudes a large amount of blood or pus, an alarm can be set in time to remind medical staff to check the patient's wound.

[0030] A purification component 19 is installed at the air outlet end of the negative pressure mechanism 18, a mounting groove 20 is opened on the side wall of the mounting hanging plate 1, and a controller 21 is fixedly installed inside the mounting groove 20, the purification component 19 includes an exhaust pipe 191 fixedly installed on the outer wall of the hollow plate 181, and the exhaust pipe 191 is connected to the air outlet 186, a steel mesh 192 is fixedly installed at a position above the air outlet 186 inside the exhaust pipe 191, and the position of the exhaust pipe 191 above the steel mesh 192 is filled with an adsorption filler 193, a vent cover 194 is threadedly connected to the tube mouth of the exhaust pipe 191, and a plurality of vent holes 195 are opened on the end face of the vent cover 194, and the adsorption filler 193 is selected from activated carbon fillers.

After the current value reaches the preset value, the blood counter 235 and the pus counter 236 will output an electrical signal to the controller 21. This is an existing mature technology, so it will not be elaborated here.

[0033] A groove 24 is provided on the side wall of the hemispherical block 234, and an arc-shaped heat-conducting insulating block 25 is fixedly encapsulated in the notch of the groove 24.

The second electromagnetic switch 27 is electrically connected to the buzzer 237 through the controller 21. When the temperature at the thermistor 26 increases, its own resistance will decrease.

[0034] The operating principle of the present invention is now described as follows: hang the mounting plate 1 on the guardrail of the bed and lock it with bolts (a plurality of hooks are provided on the mounting plate 1, and the hooks can be hung on the guardrail wall of the bed, and the hooks and the guardrail are locked together with the bolts on the hooks). Then, the drainage coupling tube 16 is connected and fixed with the drainage head (the drainage head is inserted into the postoperative wound of the patient), and then, the mounting cover 6 is screwed onto the drainage bottle 2, and the liquid inlet pipe 13 on the mounting cover 6 is connected and connected with the drainage hard pipe 14, and then, the cable connector on the mounting cover 6 is plugged into the controller 21 (the cable connector on the mounting cover 6 is used for the controller 21 to supply power to various electrical components on the mounting cover 6, such as the normally closed solenoid valve 11 , light bar 123, etc.), then connect the controller 21 to the external power supply circuit, and start the controller 21. After the controller 21 is started, the medical staff twists the screw 223 to move the piston 222 and the screw 223 up to a suitable height. Since the piston 222 is pulled up, the space for accommodating air inside the hollow plate 181 increases. At this time, part of the air in the drainage bottle 2 will enter the hollow plate 181 through the suction hole 182 and the suction one-way valve 183, so an initial negative pressure state will be formed in the drainage bottle 2. Under the action of negative pressure, if the patient's wound oozes blood or pus and other effusions, these liquids will enter the inside of the circular sleeve 121 through the drainage head, the drainage joint tube 16, the drainage hose 15, the drainage hard tube 14 and the liquid inlet tube 13;

[0035] The accumulated liquid entering the circular sleeve 121 will fall onto the conical disc 174 under the action of the guide ring 175. Under the gravity of the accumulated liquid, the conical disc 174 will move down a certain distance. The more the accumulated liquid, the greater the downward pressure on the conical disc 174. Therefore, the greater the distance the conical disc 174 moves down, the more the conical disc 174 moves down. When the conical disc 174 moves down, the conductive sleeve 177 will be driven to move down synchronously through the insulating rod 173, so that the conductive sleeve 177 contacts the conductive ring 178. When the conductive ring 178 contacts the conductive sleeve 177, the connection circuit of the conductive ring 178, the conductive sleeve 177 and the drive motor 188 is closed. 178 and the driving motor 188 are connected, and at this time, the length of the conductive sleeve 177 connected to the connecting loop of the conductive ring 178 and the driving motor 188 is the longest. Therefore, when the conductive ring 178 just contacts the conductive sleeve 177, the resistance of the connecting loop of the conductive ring 178, the conductive sleeve 177 and the driving motor 188 is the largest. At this time, the output power of the driving motor 188 is the smallest, so the driving motor 188 drives the impeller 185 to rotate slowly. If the amount of effusion generated in the patient's wound is large, at this time, the downward pressure on the conical disk 174 is large, so the downward movement distance of the conductive sleeve 177 will also become larger, so the conductive sleeve 177 is connected to the conductive ring 178 and the driving motor 188. The length of the connection loop of the driving motor 188 becomes shorter, so the current passing into the driving motor 188 becomes larger. At this time, the output power of the driving motor 188 becomes larger, so the rotation speed of the impeller 185 becomes faster. When the impeller 185 rotates, under the action of the impeller 185, the air near one end of the suction hole 182 is sucked by the impeller 185 and discharged through the outlet hole 186. Since the air at the suction hole 182 is discharged, the air in the drainage bottle 2 will be supplemented into the hollow plate 181 through the suction hole 182. Since the accumulated liquid enters the drainage bottle 2, it will fill the space in the drainage bottle 2. , so the negative pressure will gradually disappear. Therefore, when the effusion enters the drainage bottle 2, part of the air in the drainage bottle 2 can be extracted through the rotation of the impeller 185, so that the drainage bottle 2 always maintains a negative pressure state, and the rotation speed of the impeller 185 changes synchronously with the amount of effusion discharged (the more effusion is discharged, the faster the impeller 185 rotates), so as to avoid the negative pressure in the drainage bottle 2 being offset too quickly when the amount of effusion is large, resulting in a slowdown in the discharge speed of the effusion, and to avoid the negative pressure in the drainage bottle 2 being too large when the amount of effusion is small, resulting in the wound healing being affected by the external air pressure;

[0036] The accumulated fluid after passing through the conical disk 174 will pass through the two transparent plates 125. After the controller 21 is started, it will start the light bar 123 and the photodiode assembly 124 at the same time. The light emitted by the light bar 123 will pass through the accumulated fluid and irradiate the transparent plate 125 on one side of the photodiode assembly 124. The light will be irradiated to the photodiode assembly 124 after being filtered by the filter 126. If the accumulated fluid flowing through the two transparent plates 125 is blood, the color of the light after passing through the blood will be red, and the filter 126 only allows red light to pass. Therefore, when the accumulated fluid is blood, more red light can pass through the filter 126. At this time, the light irradiated to the photodiode assembly 124 is red. The light intensity at the photodiode component 124 is strong (higher than 1 Lux), so more photons will hit the PN junction of the photodiode component 124, exciting more electron-hole pairs, thereby increasing the intensity of the electrical signal generated by the photodiode component 124. At this time, the controller 21 amplifies the electrical signal intensity in proportion and passes it into the first electromagnetic switch 127. If the effusion is blood, the electrical signal intensity is large enough, so the current passing into the first electromagnetic switch 127 is large enough. At this time, the electromagnetic component inside the first electromagnetic switch 127 will generate sufficient magnetic attraction to attract its own moving contact, so the controller 21 will receive the first electromagnetic switch. When the closed electrical signal of the switch 127 is received, the controller 21 controls the normally closed electromagnetic valve 11 inside the blood discharge groove 8 to be energized and opened, and the blood flowing through the circular sleeve 121 will enter the circular groove 7, and flow into the blood area 4 through the blood discharge groove 8 and the drainage pipe 10 on the same side for storage. If the effusion drawn out is pus, etc., when the light of the light bar 123 passes through the pus, its light will present a color that is obviously different from red light (for example, yellow). Therefore, when the effusion is pus, since the light passing through the pus is not red light, most of this light will be blocked by the filter 126. Therefore, the light intensity that can irradiate the photodiode component 124 is small. (less than 1 Lux), at this time, the current passing into the first electromagnetic switch 127 is insufficient, so the moving contact of the first electromagnetic switch 127 will not be magnetically closed, so the controller 21 cannot receive the closing electrical signal of the first electromagnetic switch 127. At this time, the controller 21 will control the normally closed electromagnetic valve 11 on the side of the blood discharge groove 8 to be powered off, and control the normally closed electromagnetic valve 11 on the side of the pus discharge groove 9 to be powered on. Therefore, when the discharged effusion is not blood, the effusion will enter the pus area 5 through the pus discharge groove 9 and the drainage pipe 10 on the same side for storage, so that the blood can be stored separately from other effusions to avoid affecting the observation of the discharged effusion by medical staff;

[0037] The air discharged through the air outlet 186 under the rotation of the impeller 185 will enter the exhaust tube 191, and after being adsorbed and purified by the adsorption filler 193, it will be discharged through the vent 195 on the vent cover 194, thereby preventing blood or pus from being directly discharged into the ward along with the volatilization of the air;

[0038] When the driving motor 188 drives the impeller 185 to rotate, it will synchronously drive the rotating disk 231 to rotate, and the rotating disk 231 will drive the extrusion head 232 to rotate. Every time the extrusion head 232 rotates one circle, it will pass through the pressure switch 233 once, and the extrusion head 232 will squeeze the hemispherical block 234. The hemispherical block 234 will close the moving contact of the pressure switch 233 under the action of the extrusion force. When the controller 21 receives the closing electrical signal of the first electromagnetic switch 127, it will connect the connection circuit between the pressure switch 233 and the blood counter 235. When the pressure switch 233 is closed once, the blood counter 235 will receive an electrical signal, and then the blood counter 235 will increase a count. When the controller 21 does not receive the closing electrical signal of the first electromagnetic switch 127, it will connect the connection circuit between the pressure switch 233 and the pus counter 236. Every time the pressure switch 233 is closed, the pus counter 236 will increase a count. The liquid counter 236 will increase a count. As the amount of blood or pus discharged increases, the output power of the drive motor 188 will also increase synchronously. Therefore, the rotation speed of the rotating disk 231 will also increase. At this time, the count of the blood counter 235 or the pus counter 236 will also increase rapidly synchronously. After the count of the blood counter 235 or the pus counter 236 reaches the set value (the set value is set according to the volume of the drainage bottle 2), it means that the amount of blood or pus discharged has reached the set value. At this time, the medical staff should transfer the blood or pus in the drainage bottle 2. After the count of the blood counter 235 and the pus counter 236 reaches the set value, an electrical signal will be output to the controller 21. At this time, the controller 21 will control the buzzer 237 to start sounding an alarm. After the medical staff hears the buzzer 237, they should check whether the accumulated fluid in the drainage bottle 2 needs to be replaced.

[0039] At the same time, when the rotating disk 231 drives the extrusion head 232 to rotate, the extrusion head 232 will intermittently contact and rub with the arc-shaped heat-conducting insulating block 25 on the hemispherical block 234. Under the action of friction, the extrusion head 232 and the arc-shaped heat-conducting insulating block 25 will generate heat. If the amount of effusion generated by the patient is small, the output power of the driving motor 188 is in a relatively low state. At this time, the rotation speed of the rotating disk 231 is low, so the interval time of the contact and friction between the extrusion head 232 and the arc-shaped heat-conducting insulating block 25 is long. Therefore, the heat at the extrusion head 232 and the arc-shaped heat-conducting insulating block 25 can be dissipated in time. On the contrary, if the amount of effusion generated by the patient is large, the output power of the driving motor 188 is in a high state. At this time, the rotation speed of the rotating disk 231 is high, and the interval time of the contact and friction between the extrusion head 232 and the arc-shaped heat-conducting insulating block 25 is short. Therefore, the arc-shaped heat-conducting insulating block 25 will be frequently rubbed by the extrusion head 232, resulting in heat inefficiency. The temperature at the thermistor 26 will rise to a set value (the set value is 40°C, and the temperature range detected by the thermistor 26 is 0°C to 100°C. Within this range, the thermistor 26 will reduce its own resistance as the temperature rises). At this time, the resistance of the connection circuit between the thermistor 26 and the second electromagnetic switch 27 will decrease. Therefore, the current passed into the second electromagnetic switch 27 is large enough. At this time, the moving contact of the second electromagnetic switch 27 will be magnetically closed. When the controller 21 receives the closing electrical signal of the second electromagnetic switch 27, the controller 21 will control the buzzer 237 to sound an alarm. After hearing the buzzer 237 sounding, the medical staff will first check whether the accumulated fluid in the drainage bottle 2 needs to be transferred out. If the accumulated fluid does not need to be transferred out, the medical staff should immediately check the patient's wound, so that when the patient continuously produces a large amount of accumulated fluid, the medical staff can be reminded to check the patient's wound in time.
