Description

Technical Field

[0001] The present invention relates to the field of medical devices, and more particularly to a thoracic pressure measurement and drainage device. Background Art

[0002] Closed chest drainage is to place one end of the drainage tube into the chest cavity and connect the other end to a water-seal bottle at a lower position to discharge gas or collect fluid in the chest cavity, so that the lung tissue can reopen and restore function. As a treatment method, it is widely used in the drainage of hemothorax, pneumothorax, empyema and after thoracotomy. The chest pressure measurement and drainage device plays a very important role in the treatment of the disease.

[0003] During use, the existing chest drainage device can only simply drain the chest fluid and cannot monitor the intrathoracic pressure. If the patient has lung leakage after surgery due to factors such as intraoperative suturing technology and poor lung quality, the drainage device cannot drain the gas in the first time, causing the patient to develop subcutaneous emphysema and swelling all over the body. In addition, if the patient coughs violently after surgery, the chest pressure may increase, causing the alveoli to rupture and form pneumothorax, resulting in sudden chest tightness and difficulty breathing.

[0016] Compared with the prior art, the technical solution provided by the present invention has at least the following beneficial effects:

[0017] In the above scheme, a vacuum pump and a pressure sensor are provided. When it is necessary to drain the pleural fluid in the thoracic cavity, the second connecting tube is connected to the first connecting tube through the connecting assembly. Subsequently, the drainage tube is placed in the thoracic cavity. The pleural fluid in the thoracic cavity enters the first hollow tube and the L-shaped tube through the drainage tube and the second hollow tube. The pleural fluid flows into the vacuum pump through the L-shaped tube. The pleural fluid flows into the liquid inlet tube through the second connecting tube and the first connecting tube, and enters the drainage bottle through the liquid inlet tube for storage. When the pleural fluid passes between the second hollow tube and the first hollow tube, the pressure in the thoracic cavity can be monitored by the pressure sensor. When the thoracic cavity pressure is higher than a certain value, the vacuum pump will automatically increase the negative pressure suction, so that the liquid or gas that cannot be released in the thoracic cavity is guided to the drainage bottle through the drainage tube, thereby reducing the occurrence of subcutaneous emphysema and pneumothorax in patients and enhancing the comfort of patients.

[0018] By providing the first filter screen, when impurities in the pleural effusion need to be filtered, the pleural effusion enters the L-shaped tube through the drainage tube, the second hollow tube and the first hollow tube, and the first filter screen in the L-shaped tube can filter the impurities in the pleural effusion, and the filtered impurities slide into the storage box through the sewage outlet for storage, and then, the restrictions on the first baffle plate and the second baffle plate are released, and the knob is turned, and the knob drives the connecting rod, the round block, the first gear and the first baffle plate to rotate, and when the first baffle plate is rotated to a horizontal state, the first baffle plate seals the L-shaped tube, and the first gear can drive the rack plate to move while rotating, and the rack plate drives the second The gear and the rotating rod rotate, and the rotating rod drives the second baffle to rotate to a horizontal state, so that the first U-shaped tube can be opened. After the first baffle and the second baffle are adjusted, the handle is released, and the first spring rebounds, so that the plug is inserted into the slot, restricting the first baffle and the second baffle. When the pleural effusion enters the L-shaped tube, the pleural effusion flows into the first U-shaped tube, and is filtered through the second filter net. The pleural effusion can be discharged into the lower end of the L-shaped tube through the lower end of the first U-shaped tube. When the pleural effusion flows out of the first U-shaped tube, it will be accompanied by gas discharge, and the discharged gas can clean the impurities on the first filter net.

[0019] By providing a liquid bag and a sliding rod, when it is necessary to observe the blockage of the first filter screen, the pleural fluid enters into the L-shaped tube, and the liquid bag can be squeezed by the gravity of the pleural fluid, so that the second spring is compressed. While the second spring is compressed, it can drive the circular plate to move downward, and the circular plate can drive the connecting rod to move downward, and the connecting rod drives the sliding rod downward, and the third spring is compressed. The more the sliding rod descends, the less serious the blockage of the first filter screen is, and the less the sliding rod descends, the more serious the blockage of the first filter screen is.

[0020] By providing a suction cup, when the stability of the device needs to be improved, the second U-shaped plate is pulled, the second U-shaped plate drives the limit rod, the fourth spring is stretched, and the connecting plate limits the two limit rods. Subsequently, the pulling block is pulled upward, and the pulling block drives the thin rod, so that the thin rod drives the sliding plate to slide in the rectangular shell. While the sliding plate moves upward, the gas in the suction cup can be absorbed by the third connecting tube and the second U-shaped tube, so that the suction cup adsorbs the ground. Subsequently, the second U-shaped plate is released, so that the fourth spring rebounds, and the second U-shaped plate is engaged with the lower end of the pulling block, which limits the sliding plate and makes the suction cup adsorb to the ground, thereby further improving the stability of the device.

[0041] like Figures 1 to 11As shown, an embodiment of the present invention provides a chest pressure measurement and drainage device, including a drainage bottle 101, the top of the drainage bottle 101 is threadedly connected to a sealing cover 102, the top of the sealing cover 102 is fixedly connected to a water inlet 103 and a liquid inlet pipe 104, the liquid inlet pipe 104 runs through the sealing cover 102, the top of the liquid inlet pipe 104 is fixedly connected to a first connecting pipe 105, the top of the first connecting pipe 105 is provided with a second connecting pipe 106, the top of the second connecting pipe 106 is provided with a vacuum pump 107, the vacuum pump 10 An L-shaped tube 108 is provided on one side of 7, the vacuum pump 107 is fixedly connected between the L-shaped tube 108 and the second connecting tube 106, the top of the L-shaped tube 108 is fixedly connected to the first hollow tube 109, the top of the first hollow tube 109 is provided with a second hollow tube 110, a pressure sensor 111 is fixedly connected between the second hollow tube 110 and the first hollow tube 109, the top of the second hollow tube 110 is fixedly connected to a drainage tube 112, and a connecting component is provided between the first connecting tube 105 and the second connecting tube 106.

[0042] When the pleural fluid in the thoracic cavity needs to be drained, the second connecting tube 106 is connected to the first connecting tube 105 through the connecting assembly, and then the drainage tube 112 is placed in the thoracic cavity. The pleural fluid in the thoracic cavity enters the first hollow tube 109 and the L-shaped tube 108 through the drainage tube 112 and the second hollow tube 110, and the pleural fluid flows into the vacuum pump 107 through the L-shaped tube 108, and flows into the liquid inlet tube 104 through the second connecting tube 106 and the first connecting tube 105. The liquid inlet tube 104 enters the drainage bottle 101 for storage. When the pleural fluid passes between the second hollow tube 110 and the first hollow tube 109, the pressure in the thoracic cavity can be monitored by the pressure sensor 111. When the thoracic cavity pressure is higher than a certain value, the vacuum pump 107 will automatically enhance the negative pressure suction, so that the liquid or gas that cannot be released in the thoracic cavity is guided to the drainage bottle 101 through the drainage tube 112, thereby reducing the occurrence of subcutaneous emphysema and pneumothorax in patients and enhancing the comfort of patients.

[0043] like Figure 4 As shown, the inner wall of the L-shaped tube 108 is fixedly connected with a first filter screen 201, and the first filter screen 201 is in an inclined state. One side of the L-shaped tube 108 is fixedly connected with a rectangular frame 202, and a sewage outlet 203 is opened between the rectangular frame 202 and the L-shaped tube 108. The inner wall of the rectangular frame 202 is slidably connected with a storage box 204, and one side of the storage box 204 is fixedly connected with a pull ring.

[0044] When it is necessary to filter impurities in the pleural fluid, the pleural fluid enters the L-shaped tube 108 through the drainage tube 112, the second hollow tube 110 and the first hollow tube 109. The first filter net 201 in the L-shaped tube 108 can filter impurities in the pleural fluid, and the filtered impurities can slide into the storage box 204 through the sewage outlet 203 for storage. When it is necessary to clean the impurities in the storage box 204, pull the pull ring to pull the storage box 204 out of the rectangular frame 202, and clean the impurities in the storage box 204.

[0045] like Figure 4 As shown, the inner wall of the L-shaped tube 108 is rotatably connected to the first baffle 205, one side of the L-shaped tube 108 is fixedly connected to the first U-shaped tube 206, the inner wall of the first U-shaped tube 206 is fixedly connected to the second filter screen 207, and the inner wall of the first U-shaped tube 206 is rotatably connected to the second baffle 208.

[0046] When the first filter 201 needs to be cleaned, the first baffle 205 and the second baffle 208 are rotated to a horizontal state. When the first baffle 205 is rotated to a horizontal state, the L-shaped tube 108 can be sealed. When the second baffle 208 is rotated to a horizontal state, the first U-shaped tube 206 can be opened. When the pleural fluid enters the L-shaped tube 108, the pleural fluid can flow into the first U-shaped tube 206 under the sealing effect of the first baffle 205 on the L-shaped tube 108, and the pleural fluid is filtered through the second filter 207. The pleural fluid is discharged into the lower end of the L-shaped tube 108 through the lower end of the first U-shaped tube 206. When the pleural fluid flows out of the first U-shaped tube 206, it will be discharged with gas, and the discharged gas can clean the impurities on the first filter 201.

[0047] like Figure 5 As shown, the front end of the first baffle 205 is fixedly connected to a connecting rod 209, and the connecting rod 209 rotates and passes through the front end of the L-shaped tube 108. The front end of the connecting rod 209 is fixedly connected to a knob 210, and the outer surface of the connecting rod 209 is fixedly connected to a first gear 211. The front end of the second baffle 208 is fixedly connected to a rotating rod 212, and the rotating rod 212 rotates and passes through the front end of the first U-shaped tube 206. The outer surface of the rotating rod 212 is fixedly connected to a second gear 213. The front end of the L-shaped tube 108 is fixedly connected to an L-shaped plate 214, and one end of the rotating rod 212 is rotatably connected to the L-shaped plate 214. The front end of the L-shaped tube 108 is fixedly connected to a first U-shaped plate 215, and the inner wall of the first U-shaped plate 215 is slidably connected to a rack plate 216, and the rack plate 216 is meshed with the first gear 211 and the second gear 213.

[0048] When the first baffle 205 and the second baffle 208 need to be rotated, the knob 210 is turned, and the knob 210 drives the connecting rod 209, the first gear 211 and the first baffle 205 to rotate. When the first baffle 205 is rotated to a horizontal state, the first baffle 205 seals the L-shaped tube 108. The first gear 211 can drive the rack plate 216 to move while rotating. The rack plate 216 drives the second gear 213 and the rotating rod 212 to rotate. The rotating rod 212 drives the second baffle 208 to rotate to a horizontal state, so as to facilitate the outflow of pleural fluid through the first U-shaped tube 206.

[0049] like Figure 5 and Figure 6 As shown, the front end of the L-shaped tube 108 is fixedly connected to a fixing plate 217, one side of the fixing plate 217 is fixedly connected to a rectangular sleeve 218, the inner wall of the rectangular sleeve 218 is slidably connected to a rectangular plate 219, a first spring 220 is fixedly connected between the inner wall of the rectangular sleeve 218 and the rectangular plate 219, the front end of the rectangular plate 219 is fixedly connected to a handle 221, the handle 221 slides through the front end of the rectangular sleeve 218, one side of the rectangular plate 219 is fixedly connected to an insert block 222, the outer surface of the connecting rod 209 is fixedly connected to a round block 223, and the round block 223 is provided with a plurality of slots 224 that cooperate with the insert block 222.

[0050] When it is necessary to restrict the first baffle 205 and the second baffle 208, pull the handle 221, the handle 221 drives the rectangular plate 219 to slide in the rectangular sleeve 218, the rectangular plate 219 drives the insert block 222 to slide, and the first spring 220 is compressed. Then, turn the knob 210 to adjust the first baffle 205 and the second baffle 208 to the appropriate position, release the handle 221, the first spring 220 rebounds, so that the rectangular plate 219 drives the insert block 222 to be inserted into the slot 224 on the round block 223, thereby restricting the first baffle 205 and the second baffle 208.

[0051] like Figure 7 and Figure 8 As shown, the connecting assembly includes a T-shaped slider 225, which is fixedly connected to the bottom end of the second connecting tube 106. The top of the first connecting tube 105 is symmetrically provided with a rectangular groove 226 and a T-shaped groove 227. The rectangular groove 226 is connected to the T-shaped groove 227. The T-shaped slider 225 is slidably connected in the T-shaped groove 227. Two rubber blocks 228 are fixedly connected to the inner wall of the T-shaped groove 227.

[0052] When the first connecting tube 105 and the second connecting tube 106 need to be connected, the two T-shaped sliders 225 at the lower end of the second connecting tube 106 are respectively inserted into the rectangular grooves 226 on the first connecting tube 105. Then, the second connecting tube 106 is rotated so that the T-shaped slider 225 rotates into the T-shaped slide groove 227. The T-shaped slider 225 is rotated to the end of the T-shaped slide groove 227. When the T-shaped slider 225 contacts the rubber block 228, the T-shaped slider 225 squeezes the rubber block 228 to compress the rubber block 228. When the T-shaped slider 225 leaves the rubber block 228, the rubber block 228 rebounds to restrict the T-shaped slider 225, thereby connecting the first connecting tube 105 and the second connecting tube 106.

[0053] like Fig. 9 As shown, the inner bottom wall of the L-shaped tube 108 is fixedly connected with a liquid capsule 229, and a circular plate 230 is slidably connected inside the liquid capsule 229. Two second springs 231 are fixedly connected between the inner wall of the liquid capsule 229 and the circular plate 230. The bottom end of the circular plate 230 is fixedly connected with a connecting rod 232, and the connecting rod 232 slides through the lower end of the L-shaped tube 108.

[0054] By providing the liquid bag 229 and the second spring 231, when the pleural fluid enters into the L-shaped tube 108 and there is a lot of pleural fluid, the liquid bag 229 can be squeezed to compress the second spring 231. When the second spring 231 is compressed, the circular plate 230 can be driven to move downward, and the circular plate 230 can drive the connecting rod 232 downward, so as to facilitate the observation of the condition of the pleural fluid.

[0055] like Fig. 9 As shown, the bottom end of the L-shaped tube 108 is fixedly connected to a hollow column 233, the inner wall of the hollow column 233 is slidably connected to a sliding rod 234, the top of the sliding rod 234 is fixedly connected to the connecting rod 232, and a third spring 235 is fixedly connected between the inner wall of the hollow column 233 and the sliding rod 234, and the third spring 235 is sleeved on the outer side of the connecting rod 232.

[0056] When it is necessary to remind the cleaning of the first filter screen 201, when the pleural fluid enters the L-shaped tube 108, the liquid capsule 229 can be squeezed to compress the second spring 231. While the second spring 231 is compressed, the circular plate 230 can be driven to move downward. The circular plate 230 can drive the connecting rod 232 to move downward. The connecting rod 232 drives the sliding bar 234 downward. The third spring 235 is compressed. The more the sliding bar 234 descends, the less serious the blockage of the first filter screen 201 is, and the less the sliding bar 234 descends, the more serious the blockage of the first filter screen 201 is.

[0057] like Fig.10As shown, the bottom end of the drainage bottle 101 is fixedly connected to a bottom plate 236, one side of the bottom plate 236 is fixedly connected to a connecting plate 237, one side of the connecting plate 237 is fixedly connected to a rectangular shell 238, the inner wall of the rectangular shell 238 is slidably connected to a sliding plate 239, the top of the sliding plate 239 is fixedly connected to a thin rod 240, the thin rod 240 slides through the upper end of the rectangular shell 238, the top of the thin rod 240 is fixedly connected to a pull block 241, one side of the rectangular shell 238 is fixedly connected to a third connecting tube 242, the middle part of the bottom plate 236 is fixedly connected to a second U-shaped tube 243, one side of the second U-shaped tube 243 is fixedly connected to the third connecting tube 242, the bottom end of the bottom plate 236 is fixedly connected to four suction cups 244, and the four suction cups 244 are all fixedly connected to the second U-shaped tube 243.

[0058] When the stability of the device needs to be improved, the pull block 241 is pulled upward, and the pull block 241 drives the thin rod 240, so that the thin rod 240 drives the sliding plate 239 to slide in the rectangular shell 238. When the sliding plate 239 moves upward, the gas in the suction cup 244 can be absorbed through the third connecting tube 242 and the second U-shaped tube 243, so that the suction cup 244 adsorbs the ground, thereby further improving the stability of the device.

[0059] like Fig.11 As shown, the top of the rectangular shell 238 is fixedly connected to a limiting plate 245, and two limiting rods 246 are slidably connected to the limiting plate 245. The two limiting rods 246 both slide through the limiting plate 245, and one side of the two limiting rods 246 is fixedly connected to the same connecting plate 247, and the other side of the two limiting rods 246 is fixedly connected to the same second U-shaped plate 248, and two fourth springs 249 are fixedly connected between the second U-shaped plate 248 and the limiting plate 245, and the two fourth springs 249 are both sleeved on the outside of the two limiting rods 246.

[0060] When it is necessary to limit the sliding plate 239, pull the second U-shaped plate 248, the second U-shaped plate 248 drives the limiting rod 246, the fourth spring 249 is stretched, and the connecting plate 247 limits the two limiting rods 246. Then, pull the pull block 241 upward, the pull block 241 drives the thin rod 240, so that the thin rod 240 drives the sliding plate 239 to slide in the rectangular shell 238. While the sliding plate 239 moves upward, the gas in the suction cup 244 can be absorbed through the third connecting tube 242 and the second U-shaped tube 243, so that the suction cup 244 adsorbs the ground. Then, release the second U-shaped plate 248, so that the fourth spring 249 rebounds, and the second U-shaped plate 248 is engaged with the lower end of the pull block 241 to limit the sliding plate 239.

[0061] The working process provided by the present invention is as follows:

[0062] When the present invention is in use, the device is placed on the ground, the second U-shaped plate 248 is pulled, the second U-shaped plate 248 drives the limiting rod 246, the fourth spring 249 is stretched, and the connecting plate 247 limits the two limiting rods 246. Subsequently, the pull block 241 is pulled upward, the pull block 241 drives the thin rod 240, so that the thin rod 240 drives the sliding plate 239 to slide in the rectangular shell 238. While the sliding plate 239 moves upward, the gas in the suction cup 244 can be absorbed by the third connecting tube 242 and the second U-shaped tube 243, so that the suction cup 244 adsorbs the ground. Subsequently, the second U-shaped plate 248 is released, so that the fourth spring 249 rebounds, and the second U-shaped plate 248 is engaged with the lower end of the pull block 241, limiting the sliding plate 239. Then, the two T-shaped sliders 225 at the lower end of the second connecting tube 106 are respectively inserted into the rectangular groove 226 on the first connecting tube 105. Then, the second connecting tube 106 is rotated so that the T-shaped slider 225 rotates into the T-shaped slot 227. The T-shaped slider 225 is rotated to the end of the T-shaped slot 227. When the T-shaped slider 225 contacts the rubber block 228, the T-shaped slider 225 squeezes the rubber block 228, so that the rubber block 228 is compressed. When the T-shaped slider 225 leaves the rubber block 228, the rubber block 228 rebounds to restrict the T-shaped slider 225, and the first connecting tube 105 and the second connecting tube 106 are connected. After the connection is completed, the drainage tube 112 is placed in the chest cavity, and the pleural fluid in the chest cavity is drained through the drainage tube 112. 2 and the second hollow tube 110 enter the first hollow tube 109 and the L-shaped tube 108, the pleural fluid flows into the vacuum pump 107 through the L-shaped tube 108, the pleural fluid flows into the liquid inlet tube 104 through the second connecting tube 106 and the first connecting tube 105, and enters the drainage bottle 101 through the liquid inlet tube 104 for storage. When the pleural fluid passes between the second hollow tube 110 and the first hollow tube 109, the pressure in the thoracic cavity can be monitored by the pressure sensor 111. When the thoracic cavity pressure is higher than a certain value, the vacuum pump 107 will automatically strengthen the negative pressure suction, so that the liquid or gas that cannot be released in the thoracic cavity is guided to the drainage bottle 101 through the drainage tube 112, thereby reducing the occurrence of subcutaneous emphysema and pneumothorax in patients, enhancing the comfort of patients, and when it is necessary to remove impurities in the pleural fluid, the vacuum pump 107 will automatically increase the negative pressure suction, so that the liquid or gas that cannot be released in the thoracic cavity is guided to the drainage bottle 101 through the drainage tube 112, thereby reducing the occurrence of subcutaneous emphysema and pneumothorax in patients, enhancing the comfort of patients, and when it is necessary to remove impurities in the thoracic ... When filtering the pleural effusion, when the pleural effusion enters the L-shaped tube 108 through the drainage tube 112, the second hollow tube 110 and the first hollow tube 109, the first filter screen 201 in the L-shaped tube 108 can filter the impurities in the pleural effusion, and the filtered impurities can slide into the storage box 204 through the sewage outlet 203 for storage. When the first filter screen 201 needs to be cleaned, the handle 221 is pulled, and the handle 221 drives the rectangular plate 219 to slide in the rectangular sleeve 218, and the rectangular plate 219 drives the insert block 222 to slide, and the first spring 220 is compressed. Then, the knob 210 is turned, and the knob 210 drives the connecting rod 209, the round block 223, the first gear 211 and the first baffle 205 to rotate. When the first baffle 205 is rotated to a horizontal state,The first baffle 205 seals the L-shaped tube 108, and the first gear 211 rotates while driving the rack plate 216 to move. The rack plate 216 drives the second gear 213 and the rotating rod 212 to rotate, and the rotating rod 212 drives the second baffle 208 to rotate to a horizontal state, so that the first U-shaped tube 206 can be opened. After the first baffle 205 and the second baffle 208 are adjusted, the handle 221 is released, and the first spring 220 rebounds, so that the rectangular plate 2 The insert block 222 is driven by the insert block 19 to be inserted into the slot 224 on the round block 223 to restrict the first baffle 205 and the second baffle 208. When the pleural fluid enters the L-shaped tube 108, the pleural fluid flows into the first U-shaped tube 206 under the sealing effect of the first baffle 205 on the L-shaped tube 108, and is filtered by the second filter screen 207. The pleural fluid can be discharged from the lower end of the first U-shaped tube 206 to the lower end of the L-shaped tube 108. When the liquid flows out of the L-shaped tube 206, it will be accompanied by gas discharge. The discharged gas can clean the impurities on the first filter 201. The cleaned impurities can slide into the storage box 204 through the sewage outlet 203. Then, the pull ring is pulled to pull the storage box 204 out of the rectangular frame 202 to clean the impurities in the storage box 204. When it is necessary to observe the blockage of the first filter 201, when the pleural fluid enters the L-shaped tube 108, the liquid capsule 229 can be squeezed by the gravity of the pleural fluid, so that the second spring 231 is compressed. When the second spring 231 is compressed, the circular plate 230 can be driven to move downward. The circular plate 230 can drive the connecting rod 232 to move downward. The connecting rod 232 drives the sliding rod 234 downward. The third spring 235 is compressed. The more the sliding rod 234 descends, the less serious the blockage of the first filter 201 is. The less the sliding rod 234 descends, the more serious the blockage of the first filter 201 is.
