Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to a portable intelligent drainage device. Background Technology

[0002] Under normal circumstances, the human body contains a small amount of fluid in the pleural and abdominal cavities, which lubricate the organs within. If, under pathological conditions, the amount of fluid in these cavities increases beyond the normal physiological range, it becomes a symptom, such as pleural effusion or ascites. Surgical drainage is used to drain fluid accumulated in body cavities, joints, or tissues, including both infectious and non-infectious fluids. Drainage can reduce pressure, relieve pain, decrease the possibility of infection, and promote wound healing. Negative pressure drainage devices are designed to effectively drain accumulating fluid. Their negative pressure system ensures more thorough drainage and significantly promotes postoperative wound healing. Negative pressure drainage devices are also widely used to rescue patients with various respiratory difficulties and inability to cough effectively due to airway obstruction by vomit or secretions. Thoracic surgery departments, in particular, require various drainage devices, including: chest drainage tubes: used to remove pleural effusion or gas to reduce pleural pressure and relieve respiratory distress; pneumothorax drainage tubes: used to remove air from the pleural cavity to reduce pleural pressure and relieve respiratory distress. Empyema drainage tube: Used to drain pus from the pleural cavity to reduce intrathoracic pressure and relieve infection symptoms. Pericardial puncture drainage tube: Used to drain fluid from the pericardial cavity to reduce cardiac pressure and relieve cardiac symptoms. Hepatosplenic puncture drainage tube: Used to drain fluid from the abdominal cavity to reduce abdominal pressure and relieve abdominal symptoms. Gallbladder puncture drainage tube: Used to drain bile from the gallbladder to reduce gallbladder pressure and relieve biliary symptoms. Renal puncture drainage tube: Used to drain urine from the kidneys to reduce renal pressure and relieve urinary tract symptoms.

[0003] Traditional drainage methods involve using a negative pressure generator to create negative pressure inside the water storage bottle, and then using a suction head connected to the other end of the bottle to draw the accumulated liquid into the bottle. However, if the bottle is full, the liquid will flow directly into the negative pressure generator through the pipe, damaging the device and potentially causing further waste. Additionally, medical staff need to be distracted during surgery to monitor the liquid level in the bottle, which is detrimental to their medical procedures. Summary of the Invention

[0004] This application provides a portable intelligent drainage device to address the problem that the inventors recognize that traditional drainage methods involve creating negative pressure inside a water storage bottle using a negative pressure generator, with a suction head connected to the other end of the bottle drawing the accumulated liquid into the bottle.

[0040] Please see Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 7 , Figure 8 , Figure 12 and Figure 14In one or more embodiments, a portable intelligent drainage device is provided, including a housing 100. A negative pressure drainage device 101 is disposed inside the housing 100. The input end of the negative pressure drainage device 101 is connected to an inlet pipe 102, and the other end of the inlet pipe 102 is connected to a branch pipe 103. The other end of the branch pipe 103 extends to the outside of the housing 100. The output end of the negative pressure drainage device 101 is connected to an outlet pipe 104, and the other end of the outlet pipe 104 is connected to an adjusting housing 200. The adjusting housing 200 has a liquid storage chamber 201, an outlet hole 202, a groove 203, and a drainage channel inside. The fixed groove 204, the liquid storage chamber 201, and the outflow hole 202 are all connected to the groove 203. An outflow pipe 205 is provided on the surface of the adjusting housing 200, and the inner cavity of the outflow pipe 205 is connected to the outflow hole 202. A return spring 206 is provided inside the fixed groove 204, and a connecting rod 207 is provided on the surface of the return spring 206. The other end of the connecting rod 207 extends to the outside of the fixed groove 204 and is connected to a locking plate 208. An electromagnet 209 is provided inside the adjusting housing 200, and the locking plate 208 is made of magnetic material. A storage cavity 105 is opened inside the housing 100. The storage cavity 105 is equipped with a placement plate 106. The other end of the outflow pipe 205 extends into the storage cavity 105 and is located above the placement plate 106. There are multiple outflow pipes 205. The number of reset springs 206, electromagnets 209, connecting rods 207, and clamping plates 208 is the same as the number of outflow pipes 205. A limiting shell 107 is provided at the top of the inner wall of the storage cavity 105. A constant force spring 108 is provided inside the limiting shell 107. The top of the constant force spring 108 is connected to the top of the inner wall of the storage cavity 105, and the bottom of the constant force spring 108 is... A fixing rod 109 is provided, the bottom of which extends to the outside of the limiting housing 107 and is connected to a sealing cap 110. The other end of the outflow pipe 205 is connected to the sealing cap 110. The outflow pipe 205 is located inside the storage cavity 105 and adopts a corrugated pipe structure. A placement slot is provided on the top of the placement plate 106, and a storage bottle 300 is placed in the placement slot. A liquid level sensor 126 is provided inside the sealing cap 110. A drainage pipe is placed inside the placement shell 151. The drainage pipe can be sleeved on the surface of the branch pipe 103. An indicator light 131 is provided on the front of the housing 100.

[0041] In this embodiment, the storage bottle 300 is placed in the placement slot beforehand, and then the sealing cap 110 is pulled up to the top of the storage bottle 300. Under the action of the constant force spring 108, the sealing cap 110 can be stably fixed at this position. During this process, the outflow pipe 205 of the bellows structure can achieve a stretching effect. The operation is repeated until the storage bottle 300 is completely placed in the placement slot. When drainage is required, the drainage tube is sleeved on the surface of the branch pipe 103. After the negative pressure drainage device 101 is activated, the drainage fluid flows sequentially through the drainage tube, branch pipe 103, inlet pipe 102, outlet pipe 104, storage chamber 201, outflow hole 202, and outflow pipe 205 into the storage bottle 300. The liquid level of the storage bottle 300 is monitored by the liquid level sensor 126. When the liquid level exceeds the set threshold, the connection between the storage bottle 300 and the liquid level sensor 126 is activated. The electromagnet 209 at the outflow tube 205 causes the clamping plate 208 to block the corresponding groove 203 under the magnetic force of the electromagnet 209, and at the same time closes the corresponding electromagnet 209. Under the action of the corresponding reset spring 206, the clamping plate 208 returns to the initial position, allowing the liquid to flow into the remaining storage bottles 300. When all the liquid level sensors 126 detect the threshold and reach the peak value, the indicator light 131 will light up to alert medical staff. The surface of the clamping plate 208 is arc-shaped, and the arc shape matches the arc shape of the groove 203. Therefore, when the electromagnet 209 is energized, the clamping plate 208 can fit perfectly with the groove 203. The arc-shaped protrusion on the other side can guide the drainage fluid at this time. In conjunction with the bottom protrusion of the adjusting shell 200, the drainage fluid is guided to the correct direction.

[0042] Please see Figure 1 , Figure 2 and Figure 11 In some embodiments, the housing 100 has a storage cavity 111, an outlet cavity 112, and an adjustment cavity 113 sequentially formed inside. The storage cavity 111 and the outlet cavity 112 are connected. A rotating shaft 114 is fixedly connected inside the storage cavity 111. The surface of the rotating shaft 114 abuts against the surface of the branch pipe 103. One end of the branch pipe 103 can extend into the outlet cavity 112. An adjustment motor 115 is provided inside the housing 100. The output end of the adjustment motor 115 extends into the adjustment cavity 113 and is connected to a fixed shaft 116. A rotating rod 117 is movably connected to the inner wall of the adjustment cavity 113. A transmission belt 118 is provided on the surface of both the rotating rod 117 and the fixed shaft 116. A transmission tooth 119 is provided on the surface of the rotating rod 117. An anti-slip pad 120 is provided on the surface of the transmission tooth 119. The surface of the anti-slip pad 120 can abut against the surface of the outlet pipe 205.

[0043] In this embodiment, when the adjusting motor 115 is started, it drives the fixed shaft 116 to rotate, and at the same time, the transmission belt 118 drives the rotating rod 117 to rotate, causing the transmission gear 119 to rotate. Thus, when the anti-slip pad 120 contacts the branch pipe 103, the position of the branch pipe 103 can change. When drainage is needed, the branch pipe 103 flows out to the outside of the housing 100, and when it is not in use, the branch pipe 103 can be retracted into the housing 100 to reduce the probability of contamination. The switching between the two modes only requires switching the rotation direction of the motor. There are multiple branch pipes 103. At the same time, the number of adjusting motors 115, fixed shafts 116, rotating shafts 114, rotating rods 117, transmission belts 118, transmission gears 119 and anti-slip pads 120 are matched with the number of branch pipes 103. Thus, when a single branch pipe 103 is blocked, the drainage pipe can be connected to the other branch pipes 103 to ensure the drainage effect.

[0044] Please see Figure 6 In some embodiments, the branch pipe 103 has a first chamber 121 and a second chamber 122 inside, the first chamber 121 and the second chamber 122 are connected, the inner diameter of the first chamber 121 is smaller than the inner diameter of the second chamber 122, a ball stopper 123 is provided in the second chamber 122, the inner diameter of the ball stopper 123 is larger than the inner diameter of the first chamber 121 and smaller than the inner diameter of the second chamber 122, and a mesh plate 124 is provided inside the second chamber 122.

[0045] In this embodiment, during normal drainage, the drainage fluid flows sequentially through the first chamber 121 and the second chamber 122. Under the impact of the drainage fluid, the plug ball 123 will come into contact with the mesh plate 124, allowing the drainage fluid to flow normally. However, if backflow occurs, the impact of the backflowing fluid will cause the plug ball 123 to block the contact point between the first chamber 121 and the second chamber 122, thereby effectively preventing backflow.

[0046] Please see Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 7 , Figure 8 , Figure 11 and Figure 14In some embodiments, a gravity sensor 125 is disposed at the bottom of the placement plate 106 and below the groove 203; a liquid level sensor 126 is disposed inside the sealing cover 110; an electronic scale 127 is disposed at the bottom of the adjusting housing 200; a pressure sensor 128 is disposed on the surface of the outflow pipe 205; a timer 129 and a controller 130 are disposed inside the housing 100; and an indicator light 131 is disposed on the front of the housing 100. The components include the gravity sensor 125, the negative pressure drainer 101, the electromagnet 209, the liquid level sensor 126, and the indicator light 131. Pressure sensor 128, timer 129, electronic scale 127, and regulating motor 115 are all electrically connected to controller 130. Battery 132 is installed inside housing 100. Battery 132 is used to power gravity sensor 125, negative pressure drainer 101, electromagnet 209, liquid level sensor 126, indicator light 131, pressure sensor 128, timer 129, electronic scale 127, regulating motor 115, and controller 130. Charging cable 133 is provided on the left side of housing 100. Charging cable 133 is used to charge battery 132.

[0047] In this embodiment, the weight of the outer casing 200 can be adjusted by weighing with an electronic scale 127. The weight of the drainage fluid stored in the reservoir 201 can be determined by subtracting the initial weight from the weighed weight. Combined with the weight of the drainage fluid in the storage bottle 300 monitored by the gravity sensor 125, the specific weight of the drainage fluid can be determined, which helps medical staff in their medical operations. The pressure sensor 128 can be used to detect the liquid pressure during the drainage process. Under normal conditions, the liquid pressure of the drainage fluid is within a certain range during the drainage process. When the pressure sensor 128 detects a pressure fluctuation below the relative range, it indicates that the branch pipe 103 or the drainage pipe is blocked, and an indicator light will illuminate the blockage. 131 emits light to alert medical staff to change the connection of the drainage tube and branch tube 103. Timer 129 mainly monitors the working time of regulating motor 115. Therefore, the working time of regulating motor 115 is fixed. Combined with the fixed working speed of regulating motor 115, the displacement distance of branch tube 103 is fixed. Battery 132 is used to power gravity sensor 125, negative pressure drainage device 101, electromagnet 209, liquid level sensor 126, indicator light 131, pressure sensor 128, timer 129, electronic scale 127, regulating motor 115 and controller 130. Charging cable 133 can charge battery 132.

[0048] It should be noted that the specific models and specifications of the battery 132, charging cable 133, gravity sensor 125, negative pressure drainer 101, electromagnet 209, liquid level sensor 126, indicator light 131, pressure sensor 128, timer 129, electronic scale 127, regulating motor 115, and controller 130 in this disclosure need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail here. Its power supply and its principle are clear to those skilled in the art, and will not be described in detail here. The connection and installation of its various parts and the signal transmission principle are technologies known in this field.

[0049] Please see Figure 1 , Figure 9 and Figure 13 In some embodiments, the housing 100 has a garbage inlet 134 and a garbage storage cavity inside. Rotating rods 135 are movably connected to both sides of the inner wall of the garbage inlet 134. A torsion spring 136 is provided on the surface of the rotating rod 135. A first baffle 137 is provided on the front of the rotating rod 135. A sealing gasket 138 is provided on the front of the first baffle 137. A garbage storage box 139 is placed inside the garbage storage cavity. Bending plates 140 are provided on the front of the housing 100 and on both sides of the garbage storage cavity. A movable rod 141 is movably connected to one side of the bending plate 140. A second baffle 142 is provided on the surface of the movable rod 141. The front of the second baffle 142 can abut against the top of the bending plate 140. A connector 143 is also included. The second baffle 142 and the front of the housing 100 are connected by the connector 143.

[0050] In this embodiment, the second baffle 142 initially abuts against the top of the bent plate 140. At this time, the waste placement box 139 is placed in the waste storage cavity. Then, the second baffle 142 is flipped until it abuts against the front of the housing 100. The connection between the second baffle 142 and the housing 100 is achieved through the connector 143. When throwing the waste, the medical staff can push the first baffle 137 towards the waste inlet 134. At this time, the waste is placed above the waste storage cavity. Under the action of gravity, the waste will fall into the waste placement box 139. Then, the hand is removed from the waste inlet 134 along the original path. Under the action of the torsion spring 136, the first baffle 137 can be restored to the initial position, thereby sealing the waste inlet 134. At the same time, the sealing gasket 138 on the surface of the first baffle 137 can effectively reduce the pollution of the waste placement box 139 to the outside world. The structure of the connector 143 can adopt a detachable structure such as Velcro or buckle.

[0051] Please see Figure 1 , Figure 2 and Figure 3In some embodiments, a sealing door 144 is provided on the front of the housing 100, and an observation window 145 is provided inside the sealing door 144. A sealing gasket 138 is provided on the back of the sealing door 144, and the sealing gasket 138 can be inserted into the storage cavity 105. A connecting strap 146 is provided on the front of the housing 100, and a plug 147 is provided at the other end of the connecting strap 146. The plug 147 can be inserted into the outflow cavity 112. A self-locking universal wheel 148 is provided at the bottom of the housing 100. A handle 149 is provided on the left side of the housing 100. A slot is provided on the surface of the handle 149. The inner diameter of the slot matches the inner diameter of the charging cable 133. Hooks 150 and placement shells 151 are provided on both sides of the housing 100. The hooks 150 are located above the placement shells 151. A drainage tube is placed inside the placement shells 151. The drainage tube can be sleeved on the surface of the branch tube 103.

[0052] In this embodiment, the sealing door 144 can shield the storage cavity 105, and the sealing gasket 138 reduces the impact of external factors on the storage cavity 105. The storage cavity 105 can be observed through the observation window 145, and the outflow cavity 112 can be sealed by the plug 147, thereby further reducing the probability of external contamination of the branch tube 103. The self-locking caster wheel 148 facilitates the displacement of the drainage device, and medical staff can push it by holding the handle 149 during displacement. In the idle state, the charging cable 133 can be wound around the slot on the surface of the handle 149 to reduce the probability of adverse effects caused by the random placement of the charging cable 133. The hook 150 facilitates the hanging and placement of the corresponding drainage bag or medical device by medical staff. The placement shell 151 can be used to place the drainage tube or other medical devices that cannot be hung.

[0053] Please see Figure 10 In some embodiments, a pipe fixing clamp is also included, which includes a first semi-ring plate 400 and a second semi-ring plate 401. A magnet 402 is provided inside the first semi-ring plate 400. Both the first semi-ring plate 400 and the second semi-ring plate 401 are made of elastic material.

[0054] In this embodiment, the inner diameter of the first semi-ring plate 400 is larger than the inner diameter of the second semi-ring plate 401. The first semi-ring plate 400 is fixed to the bed handle 149 or clamped to both sides of the bed under elastic action, while the inner diameter of the second semi-ring plate 401 is smaller than the inner diameter of the drainage tube. It can be clamped to the drainage tube under elastic action, thereby fixing the position of the drainage tube. At the same time, the magnetic effect of the magnet 402 can help fix it in the corresponding position.

[0055] Specifically, the working principle of the portable intelligent drainage device provided in this application is as follows:

[0056] The storage bottle 300 is placed in the placement slot beforehand, and then the sealing cap 110 is pulled up to the top of the storage bottle 300. Under the action of the constant force spring 108, the sealing cap 110 can be stably fixed at this position. During this process, the outflow pipe 205 of the bellows structure can achieve a stretching effect. The operation is repeated until the storage bottle 300 is completely placed in the placement slot.

[0057] The starting adjustment motor 115 drives the fixed shaft 116 to rotate, and simultaneously drives the rotating rod 117 to rotate via the transmission belt 118, causing the transmission gear 119 to rotate. This allows the anti-slip pad 120 to contact the branch pipe 103, moving the branch pipe 103 to the outside of the housing 100, thus placing the drainage tube on the surface of the branch pipe 103. After activating the negative pressure drainage device 101, the drainage fluid flows sequentially through the drainage tube, branch pipe 103, inlet pipe 102, outlet pipe 104, storage chamber 201, outlet hole 202, and outlet pipe 205 into the storage bottle 300, where it is monitored by the liquid level sensor 12. 6. Monitor the liquid level of storage bottle 300. When the liquid level exceeds the set threshold, activate the electromagnet 209 at the outflow pipe 205 connected to the storage bottle 300. Under the magnetic force of the electromagnet 209, the clamping plate 208 blocks the corresponding groove 203, and at the same time, close the corresponding electromagnet 209. Under the action of the corresponding reset spring 206, the clamping plate 208 returns to the initial position, allowing the liquid to flow into the other storage bottles 300. When all liquid level sensors 126 detect the threshold and reach the peak value, the indicator light 131 will light up to remind medical staff.

[0058] The weight of the outer casing 200 can be adjusted by weighing with an electronic scale 127. The weight of the drainage fluid stored in the reservoir 201 can be obtained by subtracting the initial weight from the weighed weight. Combined with the weight of the drainage fluid in the storage bottle 300 monitored by the gravity sensor 125, the specific weight of the drainage fluid can be determined, which helps medical staff in medical operations. The pressure sensor 128 can be used to detect the liquid pressure during the drainage process. Under normal conditions, the liquid pressure of the drainage fluid is within a certain range during the drainage process. When the pressure sensor 128 detects a pressure fluctuation below the relative range, it indicates that the branch tube 103 or the drainage tube is blocked. The indicator light 131 illuminates to remind medical staff to replace the drainage tube and the connection of the branch tube 103.
